Q
  1. Proposed mechanisms of action for spinal cord
    stimulation include all of the following except:
    A. Segmental antidromic inhibition of A-beta afferents
    B. Blocking of transmission in the spinothalamic tract
    C. Supraspinal pain inhibition
    D. Activation of central inhibition of sympathetic efferent
    neurons
    E. Antidromic activation of C nociceptive afferents
A
  1. Answer: E
    Explanation:
    Reference:
    Krames, Interventional Pain Management,Second Edition;
    Chapter 53 Mechanisms of Action of Spinal Cord
    Stimulation
    A. Segmental activation of large A-beta fi bers within the
    dorsal columns which antidromically inhibit reception of
    small fi ber nociceptive information at the substantia
    gelatinosa of the dorsal horn.
    This was Melzack and Wall’s original hypothesis and is
    consistent with a classic “gate control” theory of spinal
    cord stimulation.
    B. Segmental blockade of neurotransmission in the
    spinothalamic tract.
    This theory is supported by studies that show there is
    inhibition of pain transmission locally within the cord
    during spinal cord stimulation.
    C. Spinal cord stimulation produces changes in
    supraspinal neurons that either modulate supraspinal
    pain transmission or trigger supraspinal descending
    inhibition of the dorsal horn.
    D. Activation of central inhibition of sympathetic efferent
    neurons could affect pain processing. The consistent effect
    of vasodilation supports a sympathetic inhibition effect of
    spinal cord stimulation.
    E. Release of putative neurotransmitters and/or
    neuromodulators. This theory is based on the observation
    that pain relief often outlasts the duration of stimulation
    for minutes, hours and sometimes days.

Q
740. For brachial plexus avulsion pain, the long-term outcomes
of DREZ lesioning are approximately:
A. 60-65%
B. 10-15%
C. 1-2%
D. 40-50%
E. 15-25%
A
  1. Answer: A
    Explanation:
    (Raj, Practical Mgmt of Pain, 3rd Ed., page 802)
    Long term relief of brachial plexus avulsion pain with
    DREZ lesioning is 60-65% at 3-7 years. Phantom and
    stump pain success is about 50-60%. Spinal cord injury
    pain is usually not responsive, except for end zone pain
    (segmental) occurring just below the level of injury. 70-
    75% of patients report successful relief with end zone pain.

    A. Microvascular decompression
    B. Subtemporal sensory rhizotomy
    C. Selective trigeminal rhizotomy
    D. Open trigeminal (nucleus caudalis) tractotomy
    E. Stereotactic trigeminal tractotomy
A
  1. Answer: A
    Explanation:
    (Raj, Pain Review 2nd Ed., page 311, Raj, Practical Pain
    Mgmt, 3rd Ed. Page
    798, Bonica 3rd ed. Page 2042-2043)
    Microvascular decompression, initially developed by
    Janetta, is a non-destructive and potentially curative
    operation for trigeminal neuralgia. A pulsating aberrant
    vessel loop, e.g., superior cerebellar artery (V3),
    trigeminal vein (V2), or anterior inferior cerebellar artery
    (V1), is felt to be the cause. An interposition felt of Tefl on
    or polyvinyl sponge is placed between the vessel loop and
    the trigeminal nerve. Recall, V1+V2+V3 –> TG –>
    Trigeminal Nerve –> Brainstem. Although, complications
    such as cerebellar or brainstem strokes, CSF leaks,
    meningitis…complication rates are

Q
743. Dextrose is added to lidocaine, during a spinal anesthetic.
Which position would most likely result in anesthesia of
the sacral dermatomes?
A. Prone
B. Side-lying
C. Jack Knife
D. Sitting upright
E. Trendelenburg
A
  1. Answer: D
    Explanation:
    (Raj, Practical Management of Pain, 3rd Ed., page 632,
    635)
    Baricity of a local anesthetic is described as the density of a
    local anesthetic solution divided by the density of CSF. The
    density of CSF is 1.001 to 1.005 at 37°C. Local anesthetic
    solutions are characterized relative to CSF as hyperbaric,
    hypobaric, or isobaric. Understanding this density
    relationship allows the anesthesiologist to take advantage
    of the characteristics of the local anesthetic or the position
    of the patient to direct local anesthetic toward the
    dermatomes to be anesthetized. A hyperbaric solution has
    a higher specifi c gravity than CSF, so that it moves to lowlying
    parts of the subarachnoid.
    Although prone may result in blockade of the sacral
    dermatomes, the sitting position would do this most
    effectively, by having the bulk of the local anesthetic dose
    go towards the sacral nerve roots.

relief of trigeminal neuralgia is:
A. Glycerol rhizolysis
B. Balloon-catheter decompression
C. Microvascular decompression
D. Radiofrequency thermocoagulation
E. Radiosurgery
A
  1. Answer: D
    Explanation:
    (Raj, Pain Review 2nd Ed, page 311)
    Radiofrequency thermocoagulation of the trigeminal
    ganglion is the most widely practiced percutaneous
    intervention. MVD and radiosurgery are not percutaneous
    methods.

Q
745. What percentage of patients is affl icted by
glossopharyngeal neuralgia compared to trigeminal
neuralgia?
A. 0.1-0.5%
B. 1-2%
C. 10-15%
D. 30-40%
E. 10-20%
A
  1. Answer: B
    Explanation:
    (Raj, Pain Review 2nd Ed., page 312)
    Glossopharyngeal neuralgia affl icts 1-1.3% as many
    individuals as trigeminal neuralgia. The lancinating,
    paroxysmal qualities are similar but the pain is located at
    the base of the tongue, throat, and deep in the ear. Triggers
    include chewing and swallowing. GPN may rarely be
    associated with syncope or bradycardia.

772. Which statement regarding occipital nerve stimulation is true: A. The electrode is placed transversely in the subcutaneous tissue plane overlying C1-2. B. The technique is contra-indicated in patients who have undergone posterior cervical spine surgery. C. Paresthesias are typically felt in the ipsilateral occiput and down the ipsilateral arm D. Bilateral occipital leads are contraindicated E. A stimulation trial is not necessary prior to implant
772. Answer: A Explanation: With occipital nerve stimulation, the lead is placed transversely in the subcutaneous tissue plane overlying C1-2, Unilateral or bilateral leads can be placed depending on the patients’ pain pattern. Paresthesias are typically felt in the occiput and sometimes in the posterior neck and shoulder but do not radiate down the arm.The technique is extraspinal so it can be used in patients’ who have undergone previous posterior cervical spine surgery. As with all neurostimulation, a successful trial of stimulation is a necessary prerequisite for implant.

778. Answer: E Explanation: (Raj, Pain Review 2nd Ed., pages 309-311) Cingulotomy, anterior capsulotomy (anterior limb of internal capsule), leucotomy (pre-frontal lobotomy), and hypothalamotomy have been used for intractable cancer pain in multiple sites and for psychiatric disorders, such as obsessive compulsive disorders. Hypothalamotomy, in fact, may be benefi cial if there is a strong emotional component to the pain. Subtemporal sensory rhizotomy was the main operation performed for trigeminal neuralgia before the 1950s’. Unfortunately, recurrence rates ranged from 5-20% and there was a high incidence of complications: anesthesia dolorosa, dyesthesias, keratitis. Source: Schultz D, Board Review 2004

781. In which of the following types of patients would you expect the best results following a surgical sympathectomy? A. Failure of response to sympathetic blocks B. Raynaud’s syndrome C. Diabetic peripheral neuropathy D. Phantom limb pain E. Spinal cord injury end zone pain
781. Answer: B Explanation: (Raj, Practical Management of Pain, page 803; Raj, Pain Review 2nd Ed. Page 314). All surgical sympathectomy should be prognosticated by a series of sympathetic blocks which unequivocally give a positive response. That being said, all of the above disorders may have a sympathetically maintained component. However, a painful vasospastic disorder such asRaynaud’s or complex regional pain syndrome would do the best. Central and chronic peripheral pain syndromes are less predictable.

It can be identifi ed, by using the inferior poles of the scapulae as landmarks C. It can be helpful in performing cervical epidural anesthesia D. It is an imaginary line connecting the C7 and L5 spinous processes E. It represents needle trajectory during the performance of a spinal anesthetic
782. Answer: A Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed., page 634) Spinal anesthesia is usually instituted with a needle inserted at an easily palpable interspace below L2. Depending on the patient’s individual anatomical features, the second, third, or fourth lumbar interspace may be selected. After the most prominent point of the iliac crests is located, an imaginary line is drawn between them (Tuffi er’s line), which usually crosses the L4 spinous process or the L4-L5 interspace.

Answer: C Explanation: Reference: Bedder, Interventional Pain Management, Second Edition; Chapter 55 Implantation Techniques for Spinal Cord Stimulation Successful SCS implant requires a comfortable paresthesia sensation that overlaps the area of pain. This should be demonstrated in a trial of stimulation with the selected device prior to a decision to implant. The patient should have reasonably intact cognition because spinal cord stimulation requires the patient to turn on and off the device, keep track of the external programmer and be able to manage a certain amount of technology. Many patients with successfully implanted stimulators have paresthesia sensation in areas outside the pain target region. This is not necessarily a problem. Pain relief at low amplitudes is desirable but not required since an RF system with an external battery source can be used in these cases. Source: Schultz D, Board Review 2004

785. Which of the following regarding pontine spinothalamic tractotomy is true? A. A more caudal level of analgesia may be obtained compared to a high cervical cordotomy B. There is minimal risk of obstructive sleep apnea compared to high cervical cordotomy C. Pancoast tumor-related pain is not an indication D. One theoretical advantage over mesencephalotomy is that the neospinothalamic and paleospinothalamic fi bers are in closer proximity E. Oculomotor disturbances are common
785. Answer: D Explanation: (Raj, Pain Review 2nd Ed., pages 310; Bonica 3rd Ed., pages 2048-9 & 2052-4; Raj, Practical Mgmt of Pain 3rd Ed., pg 795) Pontine spinothalamic tractotomy produces a more rostral level of analgesia compared to a high cervical cordotomy. Hence, it was introduced for neck and shoulder pain. C1-2 cordotomy at was among the most useful procedures for unilateral cancer pain below the C5 dermatome. Both pontine spinothalamic tractotomy and high cervical cordotomy carry a similar risk of paralyzing the automatic phase of respiration and thus, causing sleep apnea. Neck and shoulder pain due to cancer, e.g., Pancoast tumor, are indications for pontine spinothalamic tractotomy. The neospinothalamic (spatial and temporal aspects of painful stimuli and more laterally located) and paleospinothalamic (affective and motivational aspects of painful stimuli and more medially located)are closer together at the pontine as compared to the midbrain (mesencephalotomy) level. Oculomotor complications are common at the midbrain level due to the proximity of the oculomotor nucleus and medial longitudinal fasciculus. However, mesencephalectomy does not carry a risk of sleep apnea. Source: Schultz D, Board Review 2004

804. The true statements about electromyography and nerve conduction velocity: A. Electromyographic changes occur within 24 h of neural injury B. Testing of neural conduction velocity is more sensitive than electromyography in the early stages of neural injury C. Increased motor potential in muscle groups occurs with neural injury D. Increased neural conduction velocity occurs with neural injury E. Changes in neural conduction velocity take weeks to become apparent after neural injury
804. Answer: B Explanation: Reference: Tollison, p 326. If neural injury is suspected, electromyography and testing of neural conduction velocity can provide information as to the extent and location of injury. With neural injury, a decrease in motor potential in muscle groups and slowed conduction velocities occur. Neural conduction velocities are decreased quickly after neural injury. Electromyographic changes may take weeks to occur. Therefore, testing of neural conduction velocity is more sensitive than electromyography in the early stages of neural injury.

Low distress over an extended period of time C. A diagnosis of major depression D. Increased anxiety and depression from bereavement E. Recently diagnosed cancer
806. Answer: C Explanation: (Baum, pp 194-198.) ·In studying peripheral blood lymphocytes (PBLs) from patients with a major depression,it was found that they had poorer DNA repair (PBLs exposed to radiation damage) than lymphocytes obtained from nondepressed or low-distressed persons. When patients with a diagnosis of major depression were divided into low and highdistress subgroups, the PBLs from the high-distress subgroup had poorer DNA repair than the PBLs from the low-distress subgroup. ·While acute stress is immunosuppressive, chronic stress over time is associated with adaptation and can even enhance immunity. ·It is hypothesized that the impact of psychosocial stress (distress) on DNA repair could increase cancer risk. While the impact of psychosocial stress and DNA repair on the initiation of cancer has not been demonstrated, stressinduced suppression of the immune system, and enhancement of the immune system, has been shown to affect the growth and progression of neoplasms. ·The increased anxiety and depression from bereavement does produce suppressed lymphocyte proliferative response to mitogen stimulation 2 to 6 weeks after the death of a spouse.

807. A 67-year-old man with lung cancer presents with metacarpophalangeal joint pain. On physical examination, there is pain on moving his fi ngers and a spongy sensation when palpating the proximal aspects of the fi ngernails. CHOOSE ACCURATE DIAGNOSIS: A. Refl ex sympathetic dystrophy B. Ankylosing spondylitis C. Reiter syndrome D. Hypertrophic osteoarthropathy E. Charcot joint
807. Answer: D Explanation: (Goldman, 21/e, p 1558.) Hypertrophic osteoarthropathy is nail clubbing accompanied by a symmetrical polyarthritis involving the large joints and occasionally the metacarpophalangeal joints. Hypertrophic osteoarthropathy may be seen secondary to malignancy, endocarditis, vasculitis, and other pulmonary and cardiac diseases. Ankylosing spondylitis (AS) is a chronic and progressive infl ammatory disease, seen mostly in men in their thirties, that most commonly affects the spinal, sacroiliac, and hip joints. It may go undiagnosed for many years, and bilateral hip pain due to sacroiliac involvement may be clinically undetectable. It is strongly associated with HLA-B27. Examination of the spine usually reveals limitation in movement; patients in advanced stages may have a characteristic bent-over posture. Patients with AS may present with an acute nongranulomatous uveitis and limited chest expansion due to involvement of the costovertebral joints. The Schober test is positive in AS (with the patient erect, marks are made 5 cm below and 10 cm above the lumbosacral junction between the posterior superior iliac spines; the patient bends, marks are measured, and if the distance between the two marks increases by less than 4 cm there is spinal immobility). The pathogenesis of refl ex sympathetic dystrophy is unknown. The presentation may be seen after peripheral limb injury; early symptoms include pain in the limb and edema. This disorder may lead to contractures. Charcot joint is a complication of peripheral neuropathy seen in diabetic patients. Repetitive minor trauma to the foot causes deformities, which may lead to skin breakdown, erythema, edema, and callus formation.

809. A 42-year-old woman (5 ft, 3in., 170 lb) complains of sudden onset of severe pain in the right upper abdomen “under the ribs” accompanied by sweating, nausea, and a feeling of imminent collapse. The pain lasts for about two hours and then persists as a dull ache. When seen several hours later, she has normal bowel sounds, is tender throughout the abdomen, especially in the right upper quadrant, and is faintly icteric. She has noticed her urine is darker than usual but has not passed stool recently. She recalls occasional episodes of “indigestion” referred to the right upper abdomen and radiating to the shoulder. This has occurred especially after eating fried foods or after eating a meal following a long period of fasting. She has no fever but is anxious and tachycardic.The tests available are a blood count and blood chemistry including liver enzymes, alkaline phosphatase, and bilirubin. She has a WBC of 10,000. Her cellular hepatic enzymes are: AST/SGOT = 52 (2-33) and ALT/SGPT = 70 (4 to 44), alkaline phosphatase = 300 (17 to 91), bilirubin = 6.3 (0.2 to 1.0).The most probable diagnosis is A. Hepatitis A B. Intercostal neuritis C. Carcinoma of the head of the pancreas D. Gallstone obstructing common bile duct E. Biliary cirrhosis
809. Answer: D Explanation: (Braunwald, 15/e, pp 255-259, 1785. Kumar, 6/e, pp 550- 552. Junqueira, 9/e, pp 318-319. Guyton, l0/e, pp 800-801.) The most probable diagnosis is gallstones. The pattern of elevated liver enzymes, alkaline phosphatase, and bilirubin are consistent with obstructive jaundice (see table below). The presence of pain (in the right upper quadrant radiating to the shoulder) after eating a meal consisting of fried foods makes gallstones the most probable diagnosis. Similar pain often occurs in these patients when they have not eaten for long periods of time and then have a large meal. The pain is caused by the obstruction of the cystic duct or common bile duct that produces increased lumenal pressure within the bile vessels, which cannot be compensated for by cholecytokinin-induced contractions. The pain lasts for about one to four hours as a steady, aching feeling. Source: Klein RM and McKenzie JC 2002.

831. A 41-year-old man was recently in a motor vehicle accident (MVA) where he was the driver. He states he was wearing his seat belt at the time of the accident. A day after the accident, he developed neck pain that has now continued for 10 days. He notices crunching on extension and lateral bending of the neck. On physical examination, the patient has no neurologic defi cits. His neck has no areas of tenderness and there are no areas of spasm. He has normal lateral bend, extension, and fl exion of the neck. Which of the following is the most likely diagnosis? A. Ankylosing spondylitis B. Osteoarthritis C. Reiter syndrome D. Whiplash E. Wry neck
831. Answer: D Explanation: (Tierney, 42/e, p 792.) The most likely diagnosis in this patient is whiplash or cervical musculoligamental sprain or strain. Whiplashassociated disorders begin after a symptom-free period following a hyperextension or hyperfl exion injury, usually in an MVA. It is vital to perform a complete neurologic examination to exclude other causes of neck pain. Ankylosing spondylitis is a chronic and progressive infl ammatory disease that most commonly affects spinal, sacroiliac, and hip joints. Osteoarthritis most often affects the weight-bearing joints. Reiter syndrome usually causes an arthritis of the hips, and there is often a history of urethritis, conjunctivitis, and foot involvement.

833. A 29-year old female with upper extremity complex regional pain syndrome undergoes a stellate ganglion block in your offi ce pain clinic. She is otherwise healthy with normal body habitus and normal airway. She has been NPO for 12 hours. 20cc of 0.25% bupivacaine is injected incrementally over one minute with no other medication administered. 5 minutes after injection the patient complains of generalized weakness which progresses to complete unresponsiveness, apnea and hypotension over the ensuing several minutes. Eight minutes after injection, the patient continues to be completely unresponsive and apneic with a systolic blood pressure of 50. ECG monitor shows sinus bradycardia. The patient has no IV. Your fi rst action should be: A. Start an IV B. Use an ambu bag to ventilate the patient C. Intubate the patient D. Administer subcutaneous epinephrine E. Begin CPR
833. Answer: B Explanation: In resuscitation scenarios, always remember the ABCs: airway breathing circulation Immediate control of the airway is the most important and pressing concern in any arrest situation. This patient is completely apneic therefore airway management takes precedence over circulatory compromise. Since the patient has a normal airway and has been NPO, there is no immediate need to intubate if the airway can be maintained easily with a mask and ambu bag. The patient will likely regain the ability to ventilate on her own in a relatively short period of time (1-2 hours).Intubation in this patient would introduce a number of additional concerns including the potential for airway damage, the potential for bronchospasm, and issues related to timing of extubation. Intravenous access and epinephrine are circulation interventions. Starting an intravenous line is important but only after the airway is secure. Epinephrine is an extremely potent sympathomimetic and should be used very cautiously. It has the potential to cause severe hypertension and tachycardia in a patient who is not in full cardiac arrest (when the patient is in full cardiac arrest, epinephrine is indicated per ACLS guidelines). This patient is hypotensive and bradycardic secondary to sympathetic blockade. Intravenous volume perhaps with the edition of a milder vasopressor such as ephedrine is a better choice than epinephrine. Source: Schultz D, Board Review 2004

838. Answer: C Explanation: Aortic dissection is an acute abdominal emergency and best imaged with CT due to the speed of examination and ability to characterize the type of dissection without delay. MRI and ultrasound may provide appropriate imaging of an aortic dissection in the non acute setting. Angiography is reserved for cases with clinical questions not answered by the initial imaging modality and for cases where further intervention is planned such as fenestration of a dissection of placement of a stent graft for aortic aneurysm Source: Bieneman B, Board Review 2005

846. The following statements regarding TENS are true except: A. It has been used very successfully in the treatment of acute pain. B. It works by stimulating A-beta fi bers which in turn close the dorsal horn “gate” to nociceptive input. C. TENS has been shown to increase blood fl ow in the stimulated region D. The effects of TENS occur only during the stimulation period E. Conventional TENS uses a nearly continuous high frequency stimulation (60-100 Hz) and a relatively low intensity current (10-30 milliamps)
846. Answer: D Explanation: Reference: Bonica’s Management of Pain, Third Edition, Chapter 98, Transcutaneous Electrical Nerve Stimulation TENS works by stimulating A-beta fi bers which in turn close the dorsal horn “gate” to nociceptive input. It has been shown in many well-controlled studies to be highly effective for acute pain. The results of TENS for chronic pain have been less impressive although there is data to suggest that TENS is helpful for well selected patients with chronic pain. Conventional TENS uses a nearly continuous high frequency stimulation (60-100 Hz) and a relatively low intensity current (10-30 milliamps). The effects of TENS have been shown to increase blood fl ow in the stimulated area with pain relief sometimes outlasting the period of stimulation by hours to days.

``` 847. Which of the following is most appropriate for a patient with end-stage rectal cancer? A. Lissauer tractotomy B. Cingulotomy C. Hypophysectomy D. Commisural myelotomy E. Percutaneous C1-2 cordotomy ```
847. Answer: D Explanation: (Raj 2nd Ed., page 313) Midline or commissural myelotomy sections those midline fi bers just dorsal to the central canal of the spinal cord. The original intent was to lesion crossing spinothalamic neurons, which would eliminate pain, but preserve sensory function. However, pain relief extended caudally, without demonstrable caudal analgesia. This lead several investigators to postulate several alternate pain pathways. A multisynaptic short tract afferent pathway or an anterior tract located in between the posterior columns were proposed. The latter mediate pelvic and epigastric visceral pain. Nonetheless, myelotomy is indicated for bilateral pelvic and perineal pain of malignant origin. Unilateral percutaneous cordotomy is among the most useful procedures for unilateral cancer pain below C5. It targets the spinothalamic tract. Radiofrequency energy is used. Electrical stimulation (sensory to obtain a feeling of warmth or coolness on the contralateral side and motor to obtain ipsilateral cervical muscles; ipsilateral contraction of muscles below the neck implies the probe is in the corticospinal tract) is used to identify the lesion target Lissauer tractotomy is the goal of the dorsal root entry zone (DREZ) procedure…but all dorsal horn lamina (I-V) may be affected. The DREZ lesion is classically indicated for central nervous system damage related pain: brachial plexus avulsion, stump pain, spinal cord injury pain. Hypophysectomy is recommended in the treatment of metastatic prostate and breast cancer, irrespective of the hormonal responsiveness of the tumors. The analgesic mechanism is unknown, but limbic system or psychological effects are unlikely to be the reasons for pain relief. Cingulotomy, anterior capsulotomy (anterior limb of internal capsule), leucotomy (pre-frontal lobotomy), and hypothalamotomy have been used for intractable cancer pain in multiple sites and for psychiatric disorders, such as obsessive compulsive disorders.

848. Deep brain stimulation to treat primarily nociceptive pain would most likely target the: A. Periaqueductal grey B. Ventroposterolateral or Ventroposteromedial thalamus C. Caudalis subnucleus D. Nucleus gracilis E. Reticular formation
848. Answer: A Explanation: (Raj, Pain Review 2nd Ed., pages 311; Bonica 3rd Ed., pages 122, 130-2, & 153-4, ; Raj, Practical Mgmt of Pain 3rd Ed., pg 795) The periaqueductal and periventricular grey are located in the midbrain. The PAG and PVG can be excited by endogenous opioids or electrical stimulation to initiate descending antinociception. The VPM and VPL located in the thalamus are useful for deafferentation or neuropathic pain. The caudalis subnucleus, also known as the trigeminal spinal nucleus, is thought to be integral for a variety of head pain syndromes. The reticular formation may be responsible for some of the affective and motivational responses to pain and the regulation of spinal motor, respiratory, and autonomic functions: arousal and escape. Pos-synaptic touch and proprioception fi bers (dorsal column) project to the dorsal column nuclei: cuneatus and gracilis: lumbar and thoracic fi bers to the gracilis and cervical to the cuneatus.

849. All of the following are typically associated with the technical aspects of epidural anesthesia, except: A. Paramedian B. Bromage grip C. Hanging drop D. Taylor approach E. Sacral hiatus.
849. Answer: D Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed, pages 641-6, 634) A. Midline and paramedian approaches to the epidural space have been described. B. The Bromage grip is a useful technique for slow, controlled advancement of an epidural needle towards the ligamentum fl avum. The needle is fi rmly gripped between the thumb and index fi nger of the nondominant hand. The dorsum of the wrist is placed against the patient’s back. The needle is advanced by extension of the wrist while the dominant hand provides intermittent or constant pressure on the plunger, depending on whether one uses the loss-of-resistance technique to air or to saline solution, respectively. C. The negative pressure often found within the epidural space is the basis for the hanging-drop technique. This hanging-drop sign of Gutierrez is used to identify the epidural space and is usually applied for cervical epidural blockade in the seated patients. A winged needle is usually used and is advanced with both hands, as with the intermittent technique. A drop of fl uid is placed at the end of the needle once it is anchored in the interspinous ligament. Because of the persistent subatmospheric pressure within the epidural space, penetration of the ligamentum fl avum and entrance of the epidural space cause the drop to be sucked into the hub of the epidural needle. Injection of air or fl uid without resistance confi rms the position in the epidural space. D. The Taylor is used to identify the subarachnoid space by way of the L5 interspace, which is the largest interspace in the vertebral column. To enter this space, the operator introduces the spinal needle through the skin wheal approximately 1cm medial and 1cm inferior to the posterior superior iliac spine. The spinal needle is directed medial and cephalad to enter the subarachnoid space at the midline at the L5-S1 interspace. E. Identifi cation of the sacral hiatus is important for caudal epidural procedures. The sacral hiatus is formed secondary to nonfusion of the fi fth sacral vertebral arch. The hiatus is covered by the sacrococcygeal membrane and bordered by two cornua (large bony processes on each side of the hiatus). The sacral hiatus is most easily identifi ed with the patient lying in the prone or lateral position. Firm pressure is used to identify the coccyx with the nondominant index fi nger.The fi rst pair of bony protuberances in moving cephalad are the two cornua, surrounding the sacral hiatus.

853. Answer: B Explanation: Local spine tenderness elicited when palpating directly over the vertebral body is highly suggestive of vertebral body neoplasm or infection.

859. Answer: E Explanation: Blood level can be obtained for all antidepressant drugs. But not all of them have shown a correlation between the therapeutic effect and the blood level. Plasma level measurements of imipramine, desmethylimipramine, and nortriptyline are unequivocally clinically useful in certain situations. For imipramine, the percentage of favorable responses correlates with plasma levels in a linear manner between 200 and 250 ng/mL, but some patients may respond at a lower level. At levels that exceed 250 ng/mL, there is no improved favorable response, and side effects increase. Source: Laxmaiah Manchikanti, MD

860. Some physiological consequences of epidural blockade may include: A. increased peristalsis B. interference with satiety C. impaired respiratory function, by modifying respiratory drive, reducing diaphragmatic contractility, permitting increased airway hyperactivity, and impairing V/Q mismatch D. hypertension E. degree of sympathetic blockade that correlates with the degree of sensory blockade
860. Answer: A Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed, pages 639-41) A. The gastrointestinal tract is innervated by both the sympathetic and parasympathetic systems.Visceral afferent parasympathetic fi bers transmit sensations of satiety, distention, and nausea (but not pain). Parasympathetic efferent outfl ow increases tonic contraction, sphincter tone, peristalsis, and secretions. Pain is mediated via sympathetic afferents, whereas sympathetic efferent fi bers inhibit peristalsis and gastric secretions, constrict vasculature, and increase sphincter tone. Sympathetic denervation of the gastrointestinal tract by neuroaxial blockade conceivably may lead to generalized contraction of the bowel secondary to unopposed parasympathetic efferent outfl ow. The degree to which the bowel is affected after neural blockade depends on the extent of the blockade. C. It is conceivable that a high thoracic or cervical block may impair respiratory function by affecting sensory function (modifying respiratory drive), motor function (decreasing abdominal muscles, intercostal muscles, and diaphragmatic strength), and sympathetic function (unopposed cholinergic tone can lead to hyperreactive airways). Sympathetic block may diminish pulmonary blood fl ow and ventilation-perfusion ( V/Q ) mismatch. All of these changes have the potential to lead to airway closure, atelectasis, decreased blood fl ow, and diminished functional reserve capacity (FRC), causing (V/Q) mismatch and hypoxemia. Experimental evidence, however, does not support this scheme. D. The principal cardiovascular consequences of extensive epidural blockade are hypotension and bradycardia. E.The extent of sympathetic blockade, however, correlates very poorly with the sensory level. The amount of sympathetic denervation and sensory blockade might be larger than the classically taught two levels. It has been demonstrated that the sympathetic block could extend six or more spinal segments above the level of sensory blockade. Source: Shah RV, Board Review 2005

Epidural hematoma C. Anterior spinal artery syndrome D. Arachnoiditis E. Meralgia paresthetica
869. Answer: A Explanation: A.Epidural abscess is an exceedingly rare complication of spinal and epidural anesthesia. * Symptoms from an epidural abscess may not become apparent until several days after placement of the block. * The usual symptoms include severe back pain, sensory disturbances, and motor weakness. * Patients with epidural abscesses will complain of radicular pain approximately 3 days after development of the back pain. B. In an epidural hematoma severe back pain is the key feature. C. Anterior spinal artery syndrome is characterized predominantly by motor weakness or paralysis of the lower extremities. D. Arachnoiditis starts as a minimal cellular infl ammatory response. *It may follow trauma, surgery, tumors, infections, hemorrhage orsome intrathecal compound administration * Onset of symptoms varies from hours to months, resulting in delay in diagnosis * Symptoms include: - Radicular pain - Perineal sensory loss - Lower extremity paresis or paralysis * Diagnosis can be made by CT, MRI or myelography E. Meralgia paresthetica is related to entrapment of the lateral femoral cutaneous nerve as it courses below the inguinal ligament and is associated with burning pain over the lateral aspect of the thigh. It is not a complication of epidural anesthesia.

He takes 25 mg of hydrochlorothiazide daily for blood pressure control but otherwise is in good health. On physical examination, the patient is afebrile but his great toe is warm, swollen, erythematous, and exquisitely tender to palpation. He has several subcutaneous nodules in his pinna. The following is the most likely diagnosis: A. Calcium pyrophosphate dihydrate deposition disease B. Calcium oxalate deposition disease C. Monosodium urate deposition disease D. Calcium phosphate deposition disease E. Osteoarthritis of the great toe
870. Answer: C Explanation: (Tierney, 42/e, pp 786-790.) Tophaceous gout is characterized by the fi nding in synovial fl uid of monosodium urate crystals that are needle-shaped and strongly negative birefringent (bright yellow when parallel to the axis). Gouty attacks may be precipitated by trauma, medications that inhibit tubular secretion of uric acid (aspirin, hydrochlorothiazide), surgery, stress, alcohol, or a high-protein diet. The patient may have an accumulation of tophi in and around the joints and earlobe. Radiographs may show “rat bite” erosions. Pseudogout is due to calcium pyrophosphate dihydrate (CPPD) deposition disease; the crystals here are rhomboid-shaped and weakly positive birefringent (blue when parallel to the axis). Calcium oxalate deposition disease is usually seen in patients with end-stage renal disease; calcium phosphate deposition disease causes calcifi c tendinitis or Milwaukee shoulder.

It begins to develop in late adolescence
873. Answer: C Explanation: (Kaplan, pp 206-223.) Freud maintained that the superego begins to develop around the age of 5 or 6 as part of the resolution of the Oedipus complex.At the end of the phallic stage of psychosexual development (which lasts from around 211> to 6 years of age), children must abandon the sexual and aggressive impulses that were directed toward their parents to avoid the parents’ strong disapproval. In abandoning these impulses, children identify with their parents. Part of this identifi cation involves the internalization of parental standards of morality; this internalization marks the beginning of the superego. Source: Ebert 2004

``` 875. Which of the following negative emotional states or conditions most commonly precedes relapse in the treatment of addictive behaviors? A. Stress B. Depression C. Anxiety D. Anger E. Frustration ```
875. Answer: C Explanation: (Taylor, pp 108-114.) Negative emotional states of anxiety, depression, anger, frustration, and stress are related to relapse in the treatment of addictive behaviors involved in such disorders as alcoholism, smoking, obesity, and drug addiction. Most patients (about 70%) have negative affects preceding the relapse. The most common negative affect or mood state is anxiety related to the need for the addicting substance to relieve the anxiety. This is followed by anger, frustration, and depression. Furthermore, patients are at increased risk for relapse if they smoke, drink, eat, and so on in an attempt to reduce negative affect.

876. A 40-year-old man is asked to be evaluated by the company physician because he failed a mandatory random drug screen. The history indicates a pattern of substance abuse. The psycosocial factor most likely to be found in this person is A. Delusions of grandeur B. Depression mood C. Rationalization D. Denial E. Antisocial behavior
876. Answer: D Explanation: (Sierles, pp 295-296. Ebert pp 233-259.) Even though there is no single personality type associated with substance abuse, denial is the major psychosocial factor in these persons. Denial can also complicate the treatment, even though the substance abuser may admit to the addiction. Substance abusers do frequently display delusions of grandeur, are often in a depressed mood, frequently display antisocial behavior, and often rationalize their behavior or situation, but denying the seriousness of their drinking or drug problem and its effect on their life or loved ones is the most common psychosocial factor seen. Denial is a form of self-deception that permeates their psychological and social behavior. A physician must be constantly aware of the infl uence of denial on the patient’s self-reported history and the effect of denial on prognosis. Source: Ebert 2004

880. In a patient with spinal stenosis at L5/S1 levels with history of low back and lower extremity pain, the likely electrodiagnostic fi ndings are as follows: A. Reduced amplitude of H-have response B. Increased amplitude of the somatosensory evoked response C. Normal F-wave response D. Reduced conduction velocity of the genitofemoral nerve E. Fibrillation in tibialis anterior
880. Answer: A Explanation: Slowing of nerve conduction velocity occurs through the region of neurologic impairment. Needle EMG may not show evidence of membrane instability. Motor unit action potentials may have increased amplitude and duration because of collateral innervation, which occurs over time. Somatosensory evoked potentials will be abnormal to varying degrees in the dermatomes of the affected nerve roots. Both F- and H-wave late responses will be abnormal. Fibrillation or sharp waves in tibialis anterior are seen with involvement of L4 nerve root.

888. In traditional psychoanalysts, transference is the process wherein: A. Psychic energy, or libido, is transferred from the id to the ego and superego B. A patient invests the analyst with attitudes and feelings derived from vital earlier associations C. Certain psychological symptoms seemingly defer to new symptoms that frequently are more accessible to analysis D. Early object choices are gradually decathected E. Latent dream content is transformed into manifest content
888. Answer: B Explanation: (Kaplan, pp 885-888.) In traditional psychoanalytic treatment, analysts purposely reveal very little about themselves to their patients. That is intended to help promote transference-to create an ambiance that facilitates a patient’s ability to transfer his or her past emotional attachments to the psychoanalyst. The analyst becomes a substitute for the parental fi gure. In positive transference, the patient becomes attached to the analyst to obtain love and emotional satisfaction, where as in negative transference the analyst is seen as an unfair, unloving, and rejecting parental fi gure. Interpretations of transference may help the patient see the positive or negative feelings as a refl ection of previous of emotional entanglements Source: Ebert 2004

889. The therapeutic action of b-adrenergic receptor blockers such as propranolol in angina pectoris is believed to be primarily the result of A. Reduced production of catecholamines B. Dilation of the coronary vasculature C. Decreased requirement for myocardial oxygen D. Increased peripheral resistance E. Increased sensitivity to catecholamines
889. Answer: C Explanation: Beta-adrenergic receptor blockers cause a slowing of heart rate, lower blood pressure, and lessened cardiac contractility without reducing cardiac output. There is also a buffering action against adrenergic stimulation of the cardiac autoregulatory mechanism. These hemodynamic actions decrease the requirement of the heart for oxygen.

895. A patient has had an implanted intrathecal infusion pump for post-laminectomy syndrome for the past 3 years. He has had relatively good pain control with a combination infusion of morphine, bupivacaine, and baclofen. You are asked to evaluate him in the emergency room for increasing low back pain associated with new onset of right leg pain and right leg weakness. Physical examination reveals positive right straight leg raising with loss of right Achilles refl ex. Plain x-ray has identifi ed the titanium catheter tip marker at the T8 level in the ventral intrathecal space. The following statement is false: A. Most patients who are diagnosed with catheter tip granuloma present with gradual loss of pain control associated with gradual onset of lower extremity neurological defi cits evolving over weeks and months. B. When catheter tip granuloma is diagnosed, surgical removal of the catheter and pump is the treatment of choice. C. MRI with and without gadolinium enhancement is the imaging study of choice to assess catheter tip granuloma. D. Baclofen when used alone in the pump for spasticity management has not been implicated in catheter tip granuloma. E. Right lumbar radiculopathy is a much likelier diagnosis than catheter tip granuloma in this patient
895. Answer: B Explanation: Reference: Management of Intrathecal Catheter-Tip Infl ammatory Masses: A Consensus Statement Hassenbusch et. Al. Pain Medicine 2002 Infl ammatory mass formation at the tip of an implanted intrathecal catheter is a rare but potentially devastating complication of intrathecal drug infusion. Hassenbush et. Al. reviewed published and unpublished case reports and their own experiences to recommend methods to diagnose and treat catheter-tip infl ammatory masses in the above article. After comprehensive review, the Hassenbush consensus panel concluded that: Fluctuations in patients’ subjective symptoms and underlying pain levels are common after the implantation of drug delivery systems, but the occurrence of new or extraordinary complaints that require unexpected analgesic dose changes should alert physicians to consider a catheter-tip mass among other possibilities in the differential diagnosis. Gradual, insidious neurological deterioration weeks or months after the appearance of subjective symptoms was the most common clinical course for catheter tip granulomas before the onset of myelopathy or cauda equina syndrome in cases reported to date. Physicians should have a low threshold for performing an imaging study to confi rm or rule out the presence of a catheter-tip mass in patients with suspicious symptoms or physical fi ndings. Unless medically contraindicated, MRI with and without intravenous gadolinium contrast enhancement is the imaging procedure of choice. CT myelogram is an acceptable alternative and is equally sensitive and reliable. Catheter-tip masses are visualized best on intravenous contrast-enhanced T2-weighted images. The mass appears as an enhancing lesion having the tip of the drug administration catheter embedded within it. Not all patients with catheter tip granuloma require catheter and pump removal. When catheter tip granuloma is diagnosed, optimal management should take into account the patient’s clinical condition, the wishes of the patient and the available options for chronic pain management. Mildly symptomatic patients with small masses that are diagnosed during investigation of diminished analgesic effi cacy or other subjective complaints have been managed safely and successfully without open surgical decompression or removal of the mass. These masses did not signifi cantly compress neural structures, nor compromise neurological function, and were treated with prompt discontinuation of intrathecal drug administration. Shrinkage or disappearance of the mass was documented on follow-up imaging studies after an interval of 2-5 months. Consequently, catheter-tip infl ammatory masses that are detected early in the clinical course can be treated safely and effectively by maneuvers directed at modifying rather than removing the drug infusion system. If the decision is made to leave the infusion system in place, the responsible physician eventually must decide whether to continue intrathecal therapy and whether to change the dose, concentration, or the drug(s) being infused. Alternatives to complete removal of the catheter and pump include ceasing or changing drug infusion and: 1.Repositioning of the catheter at a different spinal level. 2.Placing a new catheter to replace the existing catheter. 3.Allowing the catheter and pump to remain dormant for a period of time. In contrast, patients presenting with paraplegia or progressive myelopathy or with apparently fi xed neurological defi cits of short duration may require emergent operative intervention because of concern that delayed treatment could foreclose the possibility of neurological recovery. Surgical intervention to remove the mass and/or de-compress the spinal canal has restored neurological function or prevented further neurological deterioration in several reported cases. The extent of resection was limited in some cases owing to adhesions to the spinal cord or nerve roots or because of the ventral location of a mass beneath the thoracic spinal cord. Because the masses were not neoplastic, in several cases the postoperative residual mass gradually shrank or disappeared over time. Source: Schultz D, Board Review 2004

897. A 60-year-old man was involved in a motor vehicle accident and suffered multiple long bone fractures and a severe injury to the pelvis. Two days following admission to the hospital, he develops fever, tachypnea, and tachycardia. The rest of his physical examination reveals chest, neck, and conjunctival petechiae. Respiratory exam reveals scattered crackles bilaterally but no wheezes. Pulse oximetry reveals a hemoglobin saturation of 80% on room air. Which of the following is the most likely diagnosis? A. Pneumothorax B. Pneumonia C. Exacerbation of chronic obstructive pulmonary disease (COPD) D. Anemia from traumatic blood loss E. Fat embolism syndrome
897. Answer: E Explanation: (Goldman, 21/e, p 448.) The signs and symptoms of fat embolism syndrome are those of adult respiratory distress syndrome (ARDS) in association with musculoskeletal trauma. It usually occurs 2 to 4 days after the injury. The predominant feature is respiratory failure. Petechiae are found in 50 to 60% of patients, generally on the anterior chest and neck, axillae, and conjunctiva.Although fractures of the pelvis may cause life-threatening blood loss and subsequent hypovolemic shock, the patient will probably have other symptoms, such as oliguria, hypotension, pale conjunctiva, clouded sensorium, and cool extremities.

898. Following cholecystectomy, a patient is receiving bupivacaine by intrapleural infusion at 8mL/hr. The patient is noted to have a Horner’s syndrome and inadequate pain relief. The next step in managing this patient is to : A. Increase the rate of bupivacaine infusion B. Remove and reinsert the catheter C. Obtain neurology consultation D. Obtain an MRI of the head E. Perform a chest radiograph
898. Answer: B Explanation: Assuming that you wish to continue the postoperative intrapleural infusion, the catheter should be removed and replaced. A Horner’s syndrome is a recognized side effect of interpleural infusions. Poor pain relief means that the catheter not covering the area of the incision. The Horner’s syndrome means that the infusion is not intravascular

The following is the most likely diagnosis: A. Rheumatoid arthritis B. Progressive systemic sclerosis C. Dermatomyositis D. Ulcerative colitis E. Sarcoidosis
905. Answer: B Explanation: (Tierney, 42/e, pp 813-814.) The patient presents with symptoms suggestive of scleoderma or progressive systemic sclerosis (PSS). This disease, when diffuse, involves the skin, joints, lungs, heart, and gastrointestinal system. Limited systemic sclerosis (lSSc) was formerly known as the CREST syndrome (Calcinosis cutis, Raynaud’s phenomenon, Esophageal dysfunction, Sclerodactyly, and Telangiectasia). Raynaud’s phenomenon may be associated with tobacco use, medication use (ß-adrenergic blockers), or diseases such as systemic lupus erythematosus, rheumatoid arthritis, carpal tunnel syndrome, or thromboangiitis obliterans. Dermatomyositis is a systemic disease characterized by a violaceous rash of the eyelids and periorbital areas (heliotrope) and fl at, violaceous papules over the knuckles (Gottron sign). The rash seen in ulcerative colitis is pyoderma gangrenosum. These painful ulcers are large and irregular and drain purulent, hemorrhagic exudates. Sarcoidosis is a systemic disease with skin manifestations, bilateral hilar adenopathy, and pulmonary disease. Patients with sarcoidosis may present with erythema nodosum, which typically takes the form of multiple fi rm, red, painful plaques that are bilateral and most frequently distributed on the legs. Musculoskeletal fi ndings in sarcoidosis include arthritis and tenosynovitis

907. A 30-year-old obese woman presents with a 2-month history of a nonthrobbing headache that is constant and dull in nature. The headache is worsened with bending over or sneezing and on awakening in the morning. The patient also complains of blurred vision and occasional diplopia. Funduscopic examination reveals blurring of the optic discs bilaterally and no other neurologic defi cit. Which of the following is the most likely diagnosis? A. Infratentorial brain tumor B. Pseudo tumor cerebri C. Supratentorial brain tumor D. Pituitary adenoma E. Metastatic brain tumor
907. Answer: B Explanation: (Tierney, 421e, p 974.) Patients with pseudotumor cerebri (benign intracranial hypertension) present with headache and papilledema. They are often obese women in their childbearing years. Other possible causes include hypervitaminosis A and the use of oral contraceptives or antibiotics (tetracycline). Lumbar puncture will reveal an elevated opening pressure. Treatment includes weight reduction and repeated lumbar punctures to reduce intracranial pressure. A complication of pseudo tumor cerebri is blindness; patients with visual changes may require emergency optic nerve sheath decompression.Pituitary adenomas are benign tumors that may cause a bitemporal hemianopsia and endocrine disturbances, such as hyperprolactinemia (galactorrhea), acromegaly or gigantism, and Cushing’s disease. A ruptured berry aneurysm causes a subarachnoid hemorrhage (SAH). Patients present with the acute onset of severe headache, photophobia,and neck stiffness.Adults commonly have supratentorial primary brain tumors (astrocytoma including glioblastoma multiforme is the most common), while children have infra tentorial primary brain tumors (medulloblastoma is the most common). Overall, metastatic brain tumors are more common than primary brain tumors. The most common metastatic brain tumors come from the Lung, Breast, Skin, Kidney, or GI tract (mnemonic: Lots of Bad Stuff KillsGlia). The headache of tumor is often continuous; exacerbated by coughing, sneezing, movement, or the Valsalva maneuver; and worse in the morning.

``` 909. A long-distance runner develops foot pain with exercise. CHOOSE CORRECT DIAGNOSIS: A. Hammer toe B. March fracture C. Genu valgum D. Genu varum E. Bunion ```
909. Answer: B Explanation: (Seidel, 5/e, p 732.) Improper footwear results in lateral deviations of the great toe, extensor, and fl exor hallucis longus tendons (bunion formation). Hammer toe often affects the second toe. The metatarsophalangeal joint is dorsifl exed and the proximal interphalangeal joint displays plantar fl exion. A stress fracture of a metatarsal is called a march fracture. Stress fractures result in bone resorption followed by insuffi cient remodeling due to continued activity Stress fractures occur in the tibia as well as the metatarsal; examination typically reveals point tenderness and swelling. In genu varum (bowleg), the lateral femoral condyles are widely separated when the feet are placed together in the extended position. In genu recurvatum, the knee hyperextends, and in genu impressum, there is fl attening and bending of the knee to one side with displacement of the patella. Pes planus is a fl attened longitudinal arch of the foot, often called fl at foot. Morton’s neuroma causes pain in the forefoot that radiates to one or two toes with tenderness between the two metatarsals. The pain may be further aggravated by squeezing the metatarsals together.

``` 911. An aphasia is most likely to be associated with a lesion of A. The hippocampus B. The temporal lobe C. The parietal lobe D. The limbic system E. The reticular activating system ```
911. Answer: B Explanation: (Guyton, pp 669-671.) Aphasia is a language disorder in which a person is unable to properly express or understand certain aspects of written or spoken language. It is caused by lesions to the language centers of the brain, which, for the majority of persons, are located within the left hemisphere in the portions of the temporal and frontal lobes known as Wernicke’s and Broca’s areas, respectively. Language disorders caused by memory loss, which could be the result of a hippocampal lesion, are not classifi ed as aphasias.

914. The most important role of the gamma motoneurons is to A. Stimulate skeletal muscle fi bers to contract B. Maintain afferent activity during contraction of muscle C. Generate activity in Ib afferent fi bers D. Detect the length of resting skeletal muscle E. Prevent muscles from producing too much force
914. Answer: B Explanation: (Berne, 3/e, pp 117-118.) The gamma motoneurons innervate the intrafusal fi bers of the muscle spindles. When a skeletal muscle contracts, the intrafusal muscle fi ber becomes slack and the Ia afferents stop fi ring. By stimulating the intrafusal muscle fi bers during a contraction,the gamma motoneurons prevent the intrafusal muscle fi bers from becoming slack and thus maintain fi ring during the contraction

916. A Middle aged woman presents with a one year history of pain and morning stiffness accompanied by swelling of her wrists and the proximal interphalangeal joints of both hands. She also has knee pain and swelling of knee joints. Physical examination reveals synovial tenderness and swelling of her knees, wrists, and proximal interphalangeal joints. She has subcutaneous nodules in the extensor area of her right forearm.The right knee has a positive bulge sign consistent with an effusion. The most likely diagnosis is: A. Osteoarthritis B. Rheumatoid arthritis C. Septic arthritis D. Chondrocalcinosis E. Scleroderma
916. Answer: B Explanation: (Tierney, 42/e, pp 829-831.) C. A septic joint will usually produce systemic symptoms such as fever. A. Osteoarthritis produces a short period of morning stiffness and often affects the distal interphalangeal joints. D. Chondrocalcinosis is a radiologic fi nding (destructive arthropathy) associated with pseudogout or CPPD crystals. B.

``` 917. All of the following psychiatric disorders are diagnosed more often in women than in men. The most frequently diagnosed disorder in women is A. Depression B. Obsessive-compulsive disorders C. Anxiety disorders D. Bulimia E. Anorexia nervosa ```
917. Answer: A Explanation: (Fauci, pp 21-24.) The most frequently diagnosed psychological disorders in women are depression, anxiety disorders, bulimia, and anorexia nervosa. Obsessivecompulsive disorders are almost equally distributed between adult men and women(prevalence about 2%), but with a slightly higher prevalence among boys than girls. Psychological disorders may have a higher prevalence in women because men are more reluctant to consult a physician for emotional problems. Another explanation is that physicians may be more apt to diagnose vague mood and anxiety complaints as psychological if there is no obvious organic basis. Source: Ebert 2004

918. A 31-year-old man complains of daily throbbing headaches for the last 2 weeks. He has approximately eight episodes per day, each lasting 20 min. The headaches are localized to the left periorbital area and are accompanied by tearing of the left eye, left ptosis, rhinorrhea, and left facial redness. The patient remembers having a similar problem 2 years ago that lasted for 3 weeks. He did not seek medical help at that time. The patient feels that the headaches are often precipitated by drinking a glass of wine. Which of the following is the most likely diagnosis? A. Migraine headache B. Cluster headache C. Tension headache D. Trigeminal neuralgia E. Sinusitis
918. Answer: B Explanation: (Tierney, 42/e, pp 948-949.) Cluster headaches are often referred to as “suicide headaches” because of the severity of the symptoms. These recurring headaches are accompanied by facial fl ushing, nasal stuffi ness, tearing, and a partial Horner syndrome (there is no anhidrosis). They are more common in men (the usual age is 20 to 50)than women and are exacerbated by alcohol use.Migraine headaches do not have this timing or duration. Tension headaches are bilateral,non throbbing, and symmetric. They are usually located in the frontal or occipital areas of the skull and are thought to be related to muscle contraction. They are often described as being viselike. The headache of sinusitis is not abrupt in onset or cessation, and patients often have tenderness with percussion of the sinuses. Trigeminal neuralgia (tic douloureux) is a paroxysmal severe facial pain over the distribution of the trigeminal nerve. Women are affected more than men, and patients are usually over the age of 40. The pain of trigeminal neuralgia can be triggered by simply touching the skin near the nostril.

920. Migraine symptoms are most likely due to: A. Vasoconstriction. B. Epileptiform discharges. C. Cerebral edema. D. Decreased cerebral metabolism due to spreading cortical depression. E. Vasodilatation
920. Answer: D Explanation: Studies of migraine have focused on vascular factors indicating that vasoconstrictive drugs reduce the amplitude of pulsation in the superfi cial temporal artery but that this does not always reduce headache.It is believed that extracranial vasodilatation is the cause of headache and intracranial vasoconstriction is the cause of neurological symptoms. Currently, the concept that “spreading cortical depression,” which is a primary neural (not vascular) event, is the major migraine mechanism. This cortical depression leads to hypometabolic state and hypoperfusion. The role of unstable serotonergic neurotransmission in this cortical depression in migraine is being explored.

921. A 35-year old man presented with constant low back pain that radiated to the left or right upper buttock region with occasional radiation to the thigh and calf posteriorly with tingling sensation in the left heel. The symptoms started approximately a year ago when he lifted a heavy box which caused the gradual onset of low back pain at the time with increasing intensity in a week. His motor examination was grossly within normal limits. However, he had a positive left straight leg raising at 50°. There was decreased sensation to pin prick on the lateral side of the foot on the left side. The following MRI shows: A. L4/5 disc herniation B. L5/S1 disc herniation C. Large osteophyte pressing on L5 nerve root D. Large osteophyte pressing on L4 nerve root E. Facet joint arthritis causing spinal stenosis
921. Answer: B Explanation: Axial T2-weighted MRI scan at the lumbosacral level. The arrow shows the degree of disc protrusion and the effect that it is having on the pain sensitive anterior part of the dural tube (D) and, to some extent, on the S1 nerve roots (small white arrows).

922. Sumatriptan succinate is effective for the treatment of acute migraine headaches by acting as A. An antagonist at BETA1 – and BETA2 – adrenergic receptors B. A selective antagonist at histamine (H1) receptors C. An inhibitor of prostacyclin synthase D. An agonist at nicotinic receptors E. A selective agonist at 5-hydroxytryptamine 1D (5-HT1D) receptors
922. Answer: E Explanation: Sumatriptan is closely related to serotonin (5-HT) in structure, and it is believed that the drug is effective in the treatment of acute migraine headaches by virtue of its selective agonistic activity at 5-HT1D receptors. These receptors, present on cerebral and meningeal arteries, mediate vasoconstriction induced by 5-HT. In addition, 5- HT1D receptors are found on presynaptic nerve terminals and function to inhibit the release of neuropeptides and other neurotransmitters.It has been suggested that the pain of migraine headaches is caused by vasodilation of intracranial blood vessels and stimulation of trigeminovascular axons, which cause pain and release vasoactive neuropeptides to produce neurogenic infl ammation and edema. Sumatriptan acts to reduce vasodilation and the release of neurotransmitters and, therefore, reduces the pain that is associated with migraine headaches. Oher antimigraine drugs (e.g.,ergotamine and dihydroergotamine) also exhibit high affi nities for the 5- HT1D-receptor site Source: Katzung, pp 280-281.

926. A middle aged woman complains of abdominal pain that began at age 8. Multiple medical and surgical evaluations have been completely within normal limits. The patient states that she has “always been sickly” and that her mother “had the same problem.” There is no history of childhood trauma or abuse. She has been unable to work for the last 4 years. Which of the following psychological diagnoses best describes her condition? A. Somatization disorder B. Conversion disorder C. Hypochondriasis D. Major depression E. Generalized anxiety disorder
926. Answer: A Explanation: A. The patient has a somatization disorder (also called hysteria or Briquet’s syndrome). * Patients often present with a long history of physical complaints before 30 years of age. - Many have undergone comprehensive medical evaluations and surgical interventions without diagnosis of any signifi cant disease process. - They also have impaired social development because of their perceived illness. - Occupational development is also affected. - Many do not work or work at jobs limited by their perceived pain. B. In conversion disorder, there is loss of a physical function that is temporarily related to a psychosocial stressor. * Sexual dysfunction, pain, blindness, and paralysis have been described as manifestations of the psychological confl ict experienced by patients with conversion disorder. C. Hypochondriasis is the excessive preoccupation with disease and with one’s health. Hypochondriacs believe that a disease process exists despite medical evaluation and reassurance over long periods of time. * Patients must pay obsessive attention to perceived pain symptoms without signifi cant fear or depression. - They complain to family and physicians and are not reassured by normal medical examinations and test results. D. Major depression is symptomatically different from somatization disorder. E. Generalized anxiety disorder is symptomatically different from somatization disorder.

927. The daughter of a 65-year-old man describes her father as having changed from an active, vivacious, caring person to one who occasionally has trouble learning new facts, has very little motivation to do any activity, and rarely expresses feelings or emotions for his grandchildren whom he has adored. The area of the brain most apt to be involved in this type of behavior change is the A. Hypothalamus B. Reticular activating system C. Heteromodal association areas D. Limbic system E. Unimodal association areas
927. Answer: D Explanation: (Carlson, pp 91-94.) · The limbic system includes regions of the limbic cortex, as well as a group of interconnected structures that surround the core of the forebrain. · The limbic system forms a circuit whose primary function was formerly regarded as modulating motivation and emotional responses. · Studies have discribed that the hippocampal formation and the limbic cortex that surround it are involved in learning and memory, rather than emotional behavior. However, the remaining sections of the limbic system are responsible for emotions, feelings, moods, and motivation. Thus, limbic system is the site primarily responsible for his learning diffi culty, lack of motivation, and emotional feelings. Source: Ebert 2004

``` 929. A celiac plexus block is not indicated for: A. Pancreatic cancer B. Chronic pancreatitits C. Sigmoid colon diverticulitis D. Hepatic metastases E. Chronic cholecystitis ```
929. Answer: C Explanation: (Raj, Pain Review 2nd ed.) The classic indication for celiac plexus block and neurolysis is pancreatic cancer. The liver and gallbladder are also indicated. The sigmoid colon is innervated by the lumbar sympathetic chain Sympathetic innervation to the gut distal to the mid-transverse colon is supplied by the lumbar sympathetics. Note that the celiac plexus contains both parasympathetic and sympathetic fi bers. However, preganglionic sympathetics coalesce to form the greater splanchnic (T5-T9) and lesser splanchnic (T10-T11) nerves. These do not synapse in the sympathetic chain but synapse in the celiac, aortico-renal, and superior mesenteric ganglia. Source: Shah RV, Board Review 2003

938. A 22-year-old woman presents with the chief complaint of diplopia for several weeks. She admits to occasional vertigo and ataxia. Six months ago, she had urinary incontinence for 1 month. Examination of the eyes reveals nystagmus, and funduscopic exam reveals swelling of the optic nerve (papillitis). The patient has increased muscle tone of the lower extremities and is hyperrefl exic. She has bilateral extensor plantar refl exes and loss of position sense. Which of the following is the most likely diagnosis? A. Multiple sclerosis B. Friedreich’s ataxia C. Acute transverse myelitis D. Brown-Sequard syndrome E. Syringomyelia
938. Answer: A Explanation: A. The patient most likely has multiple sclerosis, a demyelinating disease characterized by visual impairment, an afferent pupillary defect (Marcus Gunn pupil),diplopia, nystagmus, limb weakness, spasticity, hyperrefl exia, extensor plantar refl exes, vertigo, ataxia, dysarthria, scanning speech, emotional lability, and bladder dysfunction. Patients with optic neuritis are at risk for developing blindness. B. Friedreich’s ataxia is an autosomal recessive disease in which young patients present with pes cavus foot deformity, spasticity, arefl exia, ataxia, and cardiomyopathy. C. Patients with acute transverse myelitis initially present with back pain followed by weakness and loss of sensation below the level of the pain. Often, there may be bladder and bowel incontinence. Transverse myelitis may be seen after vaccination or infections. D. Brown-Sequard syndrome (cord hemisection) is characterized by contralateral loss of pain and temperature and ipsilateral spasticity, weakness, hyperreflexia, extensor plantar reflex, and loss of proprioception (vibration and position sense).

Loss of medial rotation of the tibia
939. Answer: D Explanation: Compression of the common peroneal nerve would affect all muscles innervated by this nerve, including tibialis anterior, peroneus longus, and extensor digitorum longus. Loss of dorsifl exion and eversion is usually complete. The extensors of the knee joint (quadriceps femoris) are supplied by the femoral nerve, whereas the fl exors of the knee joint (the hamstrings and gracilis) are supplied by the tibial nerve and obturator nerve, respectively. The gastrocnemius and soleus muscles are the principal plantar flexors of the foot and are innervated by the tibial nerve. The popliteus is the prime medial rotator of the tibia and is also innervated by the tibial nerve. Source: Klein RM and McKenzie JC 2002.

``` 941. Increased activity of the sympathetic nervous system causes A. Penile erection B. Pupillary constriction C. Accommodation for near vision D. Bronchiolar dilation E. Gallbladder emptying ```
941. Answer: D Explanation: (Rhoades, pp 118-120.) Activation of the sympathetic nervous system produces relaxation of the smooth muscles surrounding the bronchioles, leading to bronchiolar dilation. The parasympathetic nerves are responsible for penile erection, pupillary constriction, contraction of the ciliary muscle during accommodation for near vision, and gallbladder emptying. Sympathetic stimulation causes ejaculation and pupillary dilation but does not affect the activity of the ciliary muscle or the gallbladder.

942. A 51-year-old alcoholic presents to the emergency room with horizontal nystagmus, ataxic gait, and confusion. Which of the following is the most likely diagnosis? A. Wernicke syndrome B. Niacin deficiency C. Korsakoff syndrome D. Kliiver-Bucy syndrome E. Delirium tremens
942. Answer: A Explanation: (Tierney, 42/e, p 985.) The triad of nystagmus and paralysis of eye muscles,ataxia, and confusion is associated with Wernicke syndrome. Korsakoff syndrome consists of confabulation, confusion, and recent memory loss.These disorders are often found in thiamine (B1) defi cient malnourished alcoholics and are secondary to lesions in the mamillary bodies. Niacin defi ciency (pellagra or vitamin B3 defi ciency) causes the triad of D’s (Dementia, Dermatitis, and Diarrhea). Kluver- Bucy syndrome is due to lesions in the amygdala; patients present with hypersexuality, compulsive attention to detail, docile behavior, and an inability to recognize objects visually (agnosia). Delirium tremens is seen 48 to 96 h following abstinence from alcohol; patients present with insomnia, confusion, tremors, delusions, visual hallucinations, and hyperactivity of the autonomic nervous system (i.e., sweating, tachycardia, fever,and dilated pupils).

943. The condition in which the covering of the spinal cord, along with enclosed neural tissue, forms a saclike projection through a dorsal defect in the vertebral column is termed A. Rachischisis B. Anencephaly C. Meningocele D. Meningomyelocele E. Hydrocephaly
943. Answer: D Explanation: In the family of conditions known as spina bifi da,failure of the dural portions of the developing vertebrae may expose a portion of the spinal cord and its covering. This usually occurs near the caudal end of the neural tube.If there is no projection of the spinal cord or its covering through the bony defect, the condition is generally hidden (spina bifi da occulta). However, it is termed spina bifi da cystica when spinal material traverses the defect. A. Rachischisis is an extreme example of spina bifi da cystica in which the neural folds underlying the vertebral defect fail to fuse, leaving an exposed neural plate. B.Anencephaly occurs when the cranial neural tube fails to fuse, thus resulting in lack of formation of forebrain structures and a portion of the enclosing cranium. C. In a meningocele, this is a saclike projection formed only by the meninges. D. If the projection contains neural material, it is a meningomyelocele. E. Hydrocephaly results from blockage of the narrow passageways between the ventricles or between the ventricles and the subarachnoid space. Resultant swelling of the ventricles compresses the brain against the cranial vault and may cause serious mental defi cits.

949. A 25-year-old woman is involved in a motor vehicle accident. Among her injuries is a lumbar vertebral body fracture. Which of the following most likely contributed to this injury? A. Flexion B. Extension C. Torsion D. Spondylolisthesis E. Subluxation
949. Answer: A Explanation: the person is upright. Fracture of a lumbar vertebral body may be seen in vehicular accidents when the victim is restrained during a high-speed impact by a seat belt without a shoulder harness. The rapid and extreme forward fl exion of the lumbar spine may produce a variety of spinal injuries, ranging from fractures to dislocations. Fractures suffered during falls in which the person is upright, such as may occur when someone jumps off a building, are usually compression fractures of the vertebral body. Fracture of the vertebral body will usually produce pain coincidental with the injury. Patients with fractures of the vertebral body that occur without trauma or with inconsequential trauma must be investigated for malignant processes, such as metastatic carcinoma, multiple myeloma, and unsuspected osteomyelitis.

950. The carpal bone that is most likely to dislocate anteriorly and cause a form of carpal tunnel syndrome is the A. Capitate B. Hamate C. Lunate D. Navicular E. Scaphoid
950. Answer: C Explanation: A. The capitate is frequently fractured but does not tend to dislocate into the carpal arch. B. The hamate provides an anchor for the transverse carpal ligament and is, therefore, located lateral to the carpal tunnel. C. The lunate bone tends to dislocate anteriorly into the transverse carpal arch, thereby entrapping the tendons of the extrinsic digital fl exors and compressing the median nerve. D, E. The navicular (scaphoid) bone has a tendency to fracture but does not dislocate into the carpal tunnel.

954. In Hirschsprung’s disease, neural crest cells fail to migrate to, or invade, the wall of the lower colon, resulting in a loss of peristalsis in that region and often fatal obstruction. Preganglionic neurons, which would innervate the absent intramural ganglia, originate in A. The nucleus ambiguus B. Cervical intermediolateral cell column C. Sacral levels two to four of the spinal cord D. The motor nucleus of the vagus nerve E. The ventral horn at spinal levels T12, L1, L2
954. Answer: C Explanation: A. The nucleus ambiguus is the source of preganglionic parasympathetic neurons that innervate the heart via the vagus nerve and cardiac plexus. B. Neurons arising in the cervical intermediolateral cell column are sympathetic preganglionics. C. Preganglionic parasympathetic neurons to the lower colon arise from the spinal cord at sacral levels two to four and reach the wall of the colon via pelvic splanchnic nerves. D. Preganglionic parasympathetic neurons arising from the motor nucleus of the vagus innervate the upper GI tract. E. Neurons arising from the ventral horn are primary somatic motor neurons to skeletal muscle.

955. A 32-year-old man was admitted for neurologic evaluation of a gun-shot wound received fi ve days previously A 9-mm bullet had passed through both the medial and lateral heads of the gastrocnemius muscle. The bullet had not struck bone or signifi cant arteries. Neurologic examination revealed losses of dorsifl exion and eversion of the left foot. The patient could not feel pinprick or touch on the dorsum of the left foot or anterolateral surface of the left leg. Which nerve was most likely involved in the injury? A. Sciatic nerve B. Femoral nerve C. Sural nerve D. Common peroneal nerve E. Tibial nerve
955. Answer: D Explanation: A. The sciatic nerve generally divides into the tibial and common peroneal nerves superior to the popliteal fossa. Damage to it might result in defi cits in both plantar fl exion and dorsifl exion. B. The femoral nerve innervates the quadriceps muscles of the anterior thigh. Damage to it would impair fl exion of the thigh at the hip. C. The common peroneal nerve innervates all muscles in the anterior and lateral compartments of the leg. The common peroneal nerve provides sensory innervation to the dorsum of the foot and the anterolateral surface of the legs via the superfi cial and sural/lateral sural cutaneous nerves, respectively. D. The common peroneal nerve is the lateral terminal branch of the sciatic nerve. After arising near the apex of the popliteal fossa, it descends on the popliteus muscle and winds superficially around the fibular neck. It is extremely vulnerable in this position and is the most often injured nerve in the lower extremity. E. The tibial nerve innervates plantar flexors of the posterior compartment.

``` 956. A tumor in the infratemporal fossa may gain entrance to the orbit through which of the following? A. The optic foramen B. The ethmoidal sinuses C. The pterygoid canal D. The inferior orbital fi ssure E. The superior orbital fi ssure ```
956. Answer: D Explanation: A, E. The optic foramen and superior orbital fi ssure open into the middle cranial fossa and transmit the optic nerve and the oculomotor, trochlear, and abducens nerves, respectively. B. The ethmoidal sinuses are mucosa-lined cavities within the ethmoid and adjacent bones. They drain into the nasal cavity. C. The pterygoid canal connects the middle cranial fossa with the pterygopalatine fossa and transmits the vidian nerve. D. The infratemporal fossa communicates directly with the orbit via the inferior orbital fi ssure and the pterygopalatine fossa. The fi ssure normally transmits branches of the maxillary nerve and branches of the infraorbital vessels.

957. Which statement regarding cervical nerve roots is true: A. The C7 spinal nerve exits through the C7-T1 foramen B. The C2 spinal nerve exits through the C1-2 neuroforamen. C. Sensory innervation to the occiput is supplied primarily by branches from C1 D. The greater occipital nerve originates from the ventral root of C2 E. The C6 and C7 spinal nerves are most commonly involved in cervical radiculopathy
957. Answer: E Explanation: References: 2.Gray’s Anatomy, Thirteenth American Edition. Page 960. 3.The Anatomic Relation Among the Nerve Roots, Intervertebral Foramina, and Intervertebral Discs of the Cervical Spine 4.Tanaka, The Anatomic Relation Among the Nerve Roots, Intervertebral Foramina, and Intervertebral Discs of the Cervical Spine SPINE 2000;25:286-291 5.Mercer, The Ligaments and Anulus Fibrosus of Human Adult Cervical Intervertebral Discs, SPINE 1999;24:619 There are 7 cervical spinal levels and 8 cervical spinal nerves. The fi rst two cervical nerves (C1 and C2) exit the spinal canal posterior to the atlanto-occipital and atlantoaxial joints respectively. These two nerves do not exit via a foramen. The fi rst cervical foramen is C2-3 which transmits the C3 nerve. From C2-3 to C7-T1, the spinal nerve exiting the foramen is named by the last number of the level (i.e. C3 exits the C2-3 foramen, C4 exits the C3-4 foramen and C7 exits the C6-7 foramen). The C8 nerve exits the C7-T1 foramen. Below T1, the numbering convention reverses and the exiting nerve is named for the fi rst number of the level (i.e. T2 exits the T2-3 foramen and L4 exits the L4-5 foramen). The greater occipital nerve is the medial branch of the dorsal primary ramus of C2. It supplies most of the sensory innervation to the occiput. The C1 spinal nerve is primarily motor. Degenerative changes of the intervertebral discs and nerve root impingement in the intervertebral foramen occur most commonly at the C5–C6 and C6–C7 levels. Kelsey et al investigated the epidemiology of prolapsed cervical discs in an attempt to provide descriptive statistics on this disorder and to identify possible risk factors. Most patients (75%) had prolapsed discs at either the C5–C6 or C6–C7 level. Likewise, according to Murphey et al, the frequency of cervical radiculopathy was 26% for C6, 61% for C7, and 8% for C8. The incidence of nerve root compression is high for C6 and C7. Cadaveric dissection data from Tanaka et. Al. predicts a higher incidence of radiculopathy for the C5, C6 and C7 nerve roots. The C5 nerve roots were found to exit over the middle aspect of the intervertebral disc,whereas the C6 and C7 nerve roots were found to traverse the proximal part of the disc. The C8 nerve roots had little overlap with the C7–T1 disc in the intervertebral foramen. The C6 and C7 rootlets passed two disc levels in the dural sac. Also, a high incidence of the intradural connections between the dorsal rootlets of C5, C6, and C7 segments was found. Source: Schultz D, Board Review 2004

959. Intervertebral disks have a tendency to herniate into the intervertebral foramen because the A. Annulus fi brosus is attenuated in the posterolateral regions B. Interspinous ligament reinforces the disks anteriorly and anterolaterally C. Ligamentum fl avum reinforces the intervertebral disks posteriorly D. Lumbar intervertebral disks are thicker posteriorly than anteriorly E. Posterior longitudinal ligament is stronger and more complete posteriorly than posterolaterally
959. Answer: E Explanation: (Moore, Anatomy, 4/e, pp 451-453.) Intervertebral disks are strongly reinforced ventrally and laterally by the anterior longitudinal ligaments. The posterior longitudinal ligament, although it is denticulate and attenuated laterally, reinforces the posterior aspect of the intervertebral disk. Because the posterolateral region of the disk is supported least by ligamentous structures, a nucleus pulposus that is herniated through the annulus fibrosus of the intervertebral disk will take the line of least resistance and move posterolaterally into the intervertebral foramen.In so doing, the herniation is apt to impinge on a spinal nerve of the next lower vertebral level.

Predicting the outcome of less severe psychological problems C. Evaluating the effi cacy of various drug treatments D. Assessing the potential etiology of abnormal behaviors E. Defi ning by empirical criteria a wide variety of psychiatric disorders
961. Answer: E Explanation: (Baum, pp 264-271.) The DSM-IV is a multiaxial classifi cation and categorization manual for a wide variety of psychological disorders. One of its newer contributions is that each individual is scored according to broad categories and axes so that an individual may be classifi ed as having several disorders rather than being forced into a single category or disorder. The various categories of axes are Axis I: Primary psychiatric disorders (including physical and sexual abuse, medication-induced disorders, noncompliance) Axis II: Personality disorders and mental retardation (can also be used for maladaptive personality and defense mechanisms) Axis III: General medical conditions (general physical health important to the total diagnostic picture) Axis IV: Psychosocial and environmental problems (family, personal, or situational problems that might affect the diagnosis, treatment, or program) Axis V: Global assessment of functioning (a scale of the level of functioning at the time of evaluation and at other time periods) Source: Ebert 2004

964. Among combat veterans, the greatest risk for posttraumatic stress disorder is among those who A. Were violent prior to service B. Have a prior history of depression C. Have coexisting sociopathy D. Participated in violence towards noncombatants E. Have a history of substance abuse
964. Answer: D Explanation: (Sierles, pp 264-266. Ebert, pp 341-350.) Posttraumatic stress disorder (PTSD) is a cluster of symptoms that can occur in a person after exposure to a severely stressful event (e.g., rape, combat, natural disaster). There are three categories of symptoms: reexperiencing the event (e.g., nightmares, daydreams, obsessions, fl ashbacks), withdrawal (e.g., avoiding movies about war and rape and feeling detached from others who have not experienced the event), and hyperarousal (e.g., insomnia, irritability, hypervigilance, severe anxiety). Most patients with PTSD recover, especially those with good premorbid functioning and support. The greatest risk for PTSD among combat veterans is among those who killed noncombatants, participated in atrocities, or were wounded. Another factor associated with increased risk for PTSD is violence or behavioral problems, sociopathy, or psychiatric disorders prior to the trauma. Substance abuse, including alcoholism, is also relevant. It is estimated thats many as 480,000 American veterans of the war in Vietnam have PTSD. Source: Ebert 2004

``` 966. A 36-year-old man presents with left hand weakness and atrophy of the first dorsal interosseous muscle. This may indicate damage to spinal roots A. C5 and C6 B. C6 and C7 C. C7 and C8 D. C8 and T1 E. T1 and T2 ```
966. Answer: D Explanation: The fi rst dorsal interosseous muscle is innervated by the ulnar nerve. The fi bers of the ulnar nerve reaching this muscle originate a the C8 and T1 roots. If the ulnar nerve itself is the neural element injured, it is usually because of damage at the elbow, where the ulnar nerve runs superfi cially in the groove over the ulnar condyle. All the interosseous muscles of the hand are supplied by the ulnar nerve: complete transection of that nerve will produce interosseous wasting and impaired fi nger adduction and abduction. Although the lumbrical muscles are situated alongside the interosseous muscles of the hand, only two lumbricals – those on the ulnar metacarpals – are innervated by the ulnar nerve. The other two lumbricals are innervated by the median nerve. All four lumbricals insert on the extensor sheaths of the fi ngers and participate in extension of the digits. Source: Anschel 2004

967. A 49-year-old woman is brought to the emergency room after suddenly losing consciousness. Her husband states that the patient was in good health until 2 h ago, when she suddenly complained of a severe headache. After one episode of vomiting, the patient lost consciousness. The husband states that there were no seizure-like movements and no incontinence. The patient did not take any medications, smoke, drink, or use illicit drugs. On physical examination, the patient has a regular heart rate of l00/min, respiratory rate of 16/min, and blood pressure of 120/80 mmHg, and is afebrile. Heart and lung examinations are normal. On neurologic exam, the patient responds only to painful stimuli and her deep tendon refl exes are bilaterally equal. She has bilateral fl exor plantar responses. She has neck stiffness and attempts to resist forward fl exion. Which of the following is the most likely diagnosis? A. Carotid artery thrombosis B. Embolic infarction of the brain C. Frontal lobe hemorrhage D. Subarachnoid hemorrhage E. Complicated migraine
967. Answer: D Explanation: (Tierney, 42/e, pp 961-967.) There are three types of stroke: subarachnoid hemorrhage, cerebral infarction, and intracerebral hemorrhage. This patient presented after complaining of a severe headache. She has neck stiffness and no focal defi cit on neurologic exam. The loss of consciousness requires bihemispheral dysfunction, and this along with the abrupt history is most consistent with a subarachnoid hemorrhage (SAH). Common causes of SAH include ruptured aneurysm (i.e., berry) and arteriovenous malformation (AVM). Intracerebral hemorrhage (ICH) rarely produces coma (must be signifi cantly large to do so), and patients do not complain of headache (does not involve the meninges). Patients with ICH have focal defi cits that appear abruptly slowly progress over hours. An embolic stroke can involve any carotid artery but must be bilateral to cause loss of consciousness. Patients have a history of atrial fi brillation or cardiac problems.

969. A 62-year-old man walks with his feet widely spaced; steps occur with each foot lifted abruptly and too high and brought down in a stamping manner. Choose correct description of gait: A. Ataxic gait B. Parkinsonian gait C. Spastic hemiplegic gait D. Steppage gait E. Scissor gait
969. Answer: A Explanation: (Seidel, Sle, pp 791-792.) A. Ataxic gait is often characterized by clumsiness; when steps are taken, the advancing foot is lifted high. The foot is then brought down in a slapping or stamping manner. Spastic hemiplegic gait is the result of spasticity of the involved limb. The limb is moved forward by abduction and circumduction. B. Parkinsonian gait is noted for the forward stoop of the head and shoulders, with arms slightly abducted and forearms partially fl exed; there is decreased arm swing as the feet shuffl e. Steppage gait occurs with footdrop (paralysis of the peroneal nerve); the affected foot is raised higher than normal to prevent dragging of the toe. Bilateral footdrop results in a gait resembling that of a high-stepping horse. C. Spastic diplegia gait or scissor gait occurs with extrapyramidal disorders. The patient uses short steps and drags the foot; the legs are extended and stiff and cross on each other.

970. A 35-year-old woman with Complex Regional Pain Syndrome I of the right upper extremity, develops miosis, ptosis and enophthalmos after undergoing a stellate ganglion block. She does not notice a signifi cant pain relief. No signifi cant rise in skin temperature changes was recorded to the right upper extremity. What is the most likely cause? A. Inadequate concentration of the local anesthetic B. Intravascular injection C. Subarachnoid block D. Anomalous Kuntz nerves E. Brachial plexus block
970. Answer: D Explanation: The sympathetic supply to the upper extremity is through the grey rami communicantes of C7, C8 and T1 with occasional contributions from C5 and C6. This innervation is through the stellate ganglion. Blocking the Stellate ganglion would effectively cause a sympathetic denervation of the upper extremity. In some cases the upper extremity maybe supplied by the T2 and T3 grey rami communicantes. These fi bers do not pass through the stellate ganglion. These are Kuntz’s fi bers and have been implicated in inadequate relief of sympathetically maintained pain despite a good stellate ganglion block. These fi bers can be blocked by a posterior approach. Successful block of the sympathetic fi bers to the head is indicated by the appearance of Horner’s syndrome. Successful block of the sympathetic block of the upper extremity is indicated by a rise in skin temperature, engorgement of veins on the back of the hand, loss of skin conductance response and a negative sweat test.

``` 971. A 35-year-old woman falls 12 ft off a ladder and fractures her c-spine, causing damage at the C4 level. She is initially a flaccid quadriplegic with arefl exia. This arefl exia and flaccidity usually evolve into hyperrefl exia and spasticity within A. 2 to 4 months B. 1 to 2 months C. 3 days to 3 weeks D. 1 to 3 h E. 5 to 25 min ```
971. Answer: C Explanation: Spinal shock is a transient phenomenon that occurs with damage to fi bers from upper motor neurons.The spasticity that usually develops within a few days of the spinal cord injury is presumed to represent exaggeration of the normal stretch refl exes in the limbs disconnected from upper motor neuron control. The evolution from spinal shock to spasticity is much more typical of spinal cord injuries than it is of cerebrocortical injuries, but even with cerebrocortical injuries there is usually an interval of hors to days during which limbs that eventually become hyperrefl exic and spastic are hyprorefl exic and fl accid.

972. A 29-year old female with upper extremity complex regional pain syndrome undergoes a stellate ganglion block in your offi ce pain clinic. She is otherwise healthy with normal body habitus and normal airway. She has been NPO for 12 hours. 20cc of 0.25% bupivacaine is injected incrementally over one minute with no other medication administered. 5 minutes after injection the patient complains of generalized weakness which progresses to complete unresponsiveness, apnea and hypotension over the ensuing several minutes.The following is the most likely diagnosis: A. Overdose of bupivacaine B. Total spinal anesthesia C. Spinal cord infarction D. Anaphylactic shock E. Vertebral artery injection
972. Answer: B Explanation: Reference: Gilbert, Complications and Controversies in Regional Anesthesia, in ASA Refresher Course, Chapter 6, Volume 3, ASA 2003 Neural Blockade, Cousins and Bridenbaugh, Second Edition, Chapter 22 Complications of Local Anesthetic Neural Blockade, pp. 695-718. Total spinal anesthesia refers to the condition in which an overdose of intrathecal local anesthetic is administered, resulting in blockade of the entire intraspinal neuraxis. Patients with total spinal will manifest a complete and total, albeit temporary, paralysis. Manifestations include: Blockade of C3, C4 and C5 nerve roots (C3, 4 and 5 keep the diaphragm alive) as well as all thoracic spinal nerves resulting in diaphragm and chest wall paralysis with apnea. Blockade of sympathetic fi bers with hypotension secondary to vasodilation and bradycardia. Complete muscle paralysis with loss of all voluntary movement including speech an eye opening. Unless hypotension is severe, the patient may remain awake and aware but completely unable to respond. Total spinal is the most likely diagnosis here because of the signifi cant risk of dural root sleeve injection with stellate ganglion block and the delayed and gradual onset of the event, taking several minutes to develop. The other choices can be eliminated as follows: Overdose of bupivacaine: 20 cc of 0.25% bupivacaine contains 50 mg of bupivacaine (one can easily calculate the mg/ml from the milliliters and percent of any local anesthetic. Simply multiply the percent (0.25) by 10. This will give the number of mg per milliliter (2.5). Multiply this number by the volume of 20ml to arrive at 50 mg). The following are recommended maximum single doses for common local anesthetics: lidocaine: 300 mg without epinephrine, 500 mg with epinephrine bupivacaine: 175 mg to 225 mg Although there are case reports of cardiac toxicity with direct intravascular injection of as little as 50 mg of bupivacaine, direct intravascular injection would have resulted in immediate, not delayed effects. Soft tissue infi ltration overdose of bupivacaine would require a dose in the range of 175 mg. Spinal cord infarction would be exceedingly unlikely from an injection of plain local anesthetic and the time course would be quicker. Vertebral artery injection would cause immediate seizures. Anaphylactic shock is a possibility but unlikely with the use of an amide local anesthetic. Source: Schultz D, Board Review 2004

973. A 36-year old felt a sharp pain in the neck, radiating to the dorsal aspect of the forearm when he was lifting a large box. He started experiencing numbness of the thumb and index fi nger, with decreased ability to perform biceps fl exion. On examination, a diminished biceps refl ex was found. What is the most likely cause of the patient’s problems? A. Fractured C5 vertebra B. C5/6 disc protrusion C. Facet syndrome at C5/6 D. Compression of the C5 nerve root by an osteophyte E. C4/5 disc protrusion
973. Answer: B Explanation: The patient has evidence of C6 root compression, most likely due to C5/6 disc protrusion. Pain in the neck, shoulder, medial scapula, anterior chest, lateral aspect of the upper arm, and dorsal aspect of the forearm associated with biceps and extensor carpi radialis weakness is frequently present.The patient may complain of numbness of the thumb and index fi nger.

You decide to switch antidepressant therapy to phenelzine and instruct her to wait one week after stopping fl uoxetine to start taking the new pills. She begins therapy immediately with phenyline without discontinuing fl uoxetine. Two days later, she is brought to the ED with unstable vital signs, muscle rigidity, myoclonus, and hyperthermia. What caused these fi ndings? A. Increased serotonin (5-HT) in synapses B. Increased norepinephrine in synapses C. Increased acetylcholine in synapses D. Increased dopamine in synapses E. decreased norepinephrine in synapses
975. Answer: A Explanation: Reference: Hardman, p 444. This patient has the serotonin syndrome. Serotonin is already present in increased amounts in synapses because of blockade of its reuptake by the SSRIs. The amount of serotonin that is present further increased when breakdown by MAO is inhibited. The serotonin syndrome can be life threatening. Source: Stern - 2004

A C7 nerve root lesion will also produce symptoms (pain and paresthesias) in the index and middle fi ngers as well as a diminished or absent triceps refl ex. Absence of a brachioradialis refl ex is an indication of a C6 nerve root lesion (Raj, pp 272-273). Source: Kahn CH, DeSio JM. PreTest Self Assessment and Review. Pain Management.

``` 977. If nystagmus is a prominent symptom of a cerebellar lesion, the lesion is within A. The dentate nucleus B. The fl occulonodular lobe C. The lateral cerebellum D. The cerebrocerebellar cortex E. The superior cerebellar peduncle ```
977. Answer: B Explanation: (Guyton, p 655.) The fl occulonodular lobe is known as the archeocerebellum because it is, phylogenetically, the oldest portion of the cerebellum. It is connected to the vestibular nuclei and participates in the control of eye movements. Lesions to the fl occulonodular lobe will cause nystagmus. Lesions to the other regions of the cortex, the deep nuclei of the spinocerebellar tracts, cause a variety of abnormalities in motor coordination referred to as ataxia.

978. A patient presents with onset of upper extremity pain. The physical examination revealed weakness of elbow extension and loss of sensation of the middle fi nger. The correct diagnosis in this patient is: A. C4 nerve root involvement B. C5 nerve root involvement C. C6 nerve root involvement D. C7 nerve root involvement E. C8 nerve root involvement
978. Answer: D Explanation: The C7 (radial nerve) supplies the triceps, which is the primary elbow extensor while the triceps, wrist fl exors, and fi nger extensors are partially innervated by the C8, they are predominantly C7 muscles. C7 supplies sensation to the middle fi nger. Since the middle fi nger sensation is also occasionally supplied by C6 and C8, there is no conclusive way to test the C7 sensation. Source: Hoppenfeld S.

987. The following is characteristic of trigeminal neuralgia: A. Usually due to multiple sclerosis B. Episodes may be aborted by certain antiepileptic or antispasticity medications. C. Sensory loss is detected on the face. D. Weak masseter muscle function. E. Bursts of pain last 30-60 min.
987. Answer: B Explanation: Trigeminal neuralgia develops due to demyelination of the trigeminal nerve (sensory portion). This could be due to MS plaque, neoplasm in the cerebello-pontine angle, or vascular lesion compressing the trigeminal nerve. In most cases of trigeminal neuralgia, no etiology is found and neurological examination is normal. Bursts of “electrical shock” pain usually last less than 30 sec and are confi nedto one division of the trigeminal nerve (mandibular is most common). Prior to diagnosis being established, dental origin for pain is considered, and many patients undergo unnecessary tooth extractions. Treatment includes carbamazepine, phenytoin, or baclofen. Surgical rhizotomy may be needed if medical therapy is not effective. There is a theory that the pain is due to compression of the trigeminal nerve by abnormal blood vessels, and if this is the case, microvascular decompression would be warranted.

989. Answer: E Explanation: The term thunderclap headache implies the headache is sudden and severe. This pattern should alert the physician to the possibility of SAH. Although LP with CSF exam is the most defi nitive diagnostic study for SAH, CT was done and showed fi ndings characteristic of ruptured middle cerebral artery aneurysm. Since 20% of aneurysms are multiple, a four-vessel angiogram is needed to study the entire cerebral circulation; whereas a left carotid angiogram would likely show the causal aneurysm only and not screen for the possibility of multiple aneurysms.

991. Answer: E Explanation: All listed agents are effective in treating migraine. Isometheptene in combination with acetaminophen and dichloralphenazone (Midrin) as well as caffeine are effective, possibly due to vasoconstrictive effect, despite the debate as to whether vascular factors are primary or secondary. These medications also affect serotonin receptors. Ergotamine is most effective when used parenterally and is less orally.

992. Answer: D Explanation: In cluster, patients awaken with severe short-lived headache. This is associated with autonomic dysfunction and Horner syndrome. The presence of headache with diplopia should suggest ruptured carotid aneurysm with oculomotor nerve dysfunction (ptosis, pupillary dilation, and extraocular muscle dysfunction).

995. A 30-year-old man develops “the fi rst and worst headache of his life” after 5 min of weight lifting. The headache is throbbing in quality. It causes him to stop lifting. The headache disappears in 10 min. When he goes to the emergency department (ED), he is asymptomatic and the exam is entirely normal. What is the most likely diagnosis? A. Subarachnoid hemorrhage. B. Bacterial meningitis. C. Benign exertional headache. D. Intracranial hypertension. E. Hypertensive encephalopathy.
995. Answer: C Explanation: Sudden “thunderclap” headache suggests subarachnoid hemorrhage (SAH). Because the headache lasts only 10 min and then resolves, this suggests effort migraine, especially since the patient has no meningeal sings. It would be unlikely for pain of SAH to resolve rapidly. Lack of fever excludes meningitis; normal blood pressure excludes hypertensive encephalopathy; lack of papilledema excludes intracranial hypertension. (Lancet 2, pp. 1247- 1248, 1998).

997. An 18-year-old gymnast heard a popping sound in her left knee while practicing for the Olympic Games. Her knee immediately became swollen and painful. On physical examination, it is obvious that the left knee has an effusion. The anterior drawer test and Lachman test are positive. McMurray test is negative. Which of the following is the most likely diagnosis? A. Anterior crudate ligament tear B. Posterior crudate ligament tear C. Torn medial meniscus D. Torn lateral meniscus E. Popliteal cyst
997. Answer: A Explanation: (Seidel, 5/e, pp 737-738.) The anterior and posterior cruciate ligaments are intraarticular ligaments and contribute to the stability of the knee. The most likely diagnosis in this gymnast is tear of the anterior cruciate ligament (ACL). Both the Lachman test (the patient is placed in the supine position with the knee fl exed at 15° while the examiner stabilizes the distal thigh with one hand and grasps the patient’s leg distal to the tibiofemoral joint with the other hand; the test is positive if the examiner is able to move the tibia anteriorly) and the anterior drawer test (the foot is immobilized while the hip and knee are fl exed, then the tibia is moved anterior relative to the femur; a positive test occurs with forward displacement of the tibia of more than 0.5 cm) are positive in this kind of injury. The Lachman test is more sensitive than the drawer test. Aspirated joint fl uid is usually bloody in ACL injuries. An MRI is helpful in diagnosing this injury. A posterior cruciate ligament (PCL) tear would have a positive posterior drawer test whereby posterior displacement of the tibia is elicited on physical examination. A tom medial meniscus often causes the patient to complain of knee catching, locking, and clicking. The McMurray test (with the patient supine, fl ex the knee and hold the foot in one hand; rotate the leg and slowly extend the knee while palpating the posteromedial margins of the joint for a palpable click as the femur passes over the tom meniscus) is positive for a tom medial meniscus. A tom lateral meniscus is tested by palpating the posterolateral margin of the knee joint with the leg in full internal rotation as the knee is extended. Medial meniscus tears are more common than lateral meniscus tears and are usually due to twisting injuries. Unlike the immediate swelling seen with tears of vascular structures such as the ACL, the relatively avascular meniscus (cartilage) causes more gradual swelling.

998. If the recurrent laryngeal nerve were transected bilaterally, the vocal cords would A. Be paralyzed in the open position B. Be paralyzed in the closed position C. Be paralyzed in the intermediate position D. Not be affected unless the superior laryngeal nerve were also injured E. Appear exactly the same as if an intubating dose of succinylcholine were given
998. Answer: B Explanation: The recurrent laryngeal nerve innervates all the muscles of the larynx except the cricothyroid muscle, which tenses the vocal cords and is innervated by the external branch of the superior laryngeal nerve. Bilateral transections of the recurrent laryngeal nerve would produce tense (because the superior laryngeal nerve remains intact) closed (because the muscle that opens the cords have been denervated) vocal cords. What is actually seen are fl accid closed cords. The cricothyroid muscle is evidently unable to tense the vocal cords without resistance from the other muscle in the larynx.

999. Answer: A Explanation: (Guyton, pp 655-656.) Ataxia, dysmetria, and an intention tremor all are classic fi ndings in a patient with a lesion involving the cerebellum. Affected persons also exhibit adiadochokinesia, which is a loss of ability to accomplish a swift succession of oscillatory movements, such as external and internal rotation of the foot. These symptoms all result from destruction of the normal feedback mechanisms that are coordinated in the cerebellum

``` 1000. Which of the following types of interventional procedures is associated with the greatest serum concentration of lidocaine? A. Intercostal B. Caudal C. Epidural D. Brachial plexus E. Femoral nerve block ```
1000. Answer: A Explanation: The site of injection of the local anesthetic is one of the most important factors infl uencing systemic local anesthetic absorption and toxicity. The degree of absorption from the site of injection depends on the blood supply to that site. Areas that have the greatest blood supply have the greatest systemic absorption. The greatest plasma concentration of local anesthetic occurs after an intercostal block, followed by caudal, epidural, brachial plexus, and femoral nerve block.

The L5/S1 intervertebral disc was very then and there were anterior osteophytes adjacent to on the L5 and S1 bodies. Clinically, grade I spondylolisthesis of L5 on S1 may be causing entrapment of L5 nerve root with probable L5/S1 disc bulge and protrusion. However, to rule out further abnormalities with disc herniation, patient should undergo either a CT scan or MRI. Source: Giles LGF. 50 Challenging Spinal Pain Syndrome Cases.

Malignant hyperthermia (hyperpyrexia), a syndrome that is associated with the use of a general anesthetic (e.g.,halothane) in conjunction with a skeletal muscle relaxant, is characterized by tachycardia, hyperventilation, arrhythmias, fever, muscular fasciculation, and rigidity. It is caused by a sudden increase in the availability of calcium (Ca) ions in the myoplasma of muscle. Dantrolene, which interferes with release Ca ions from the sarcoplasmic reticulum, is indicated in treatment of the disorder. The fi rst three agents are centrally acting skeletal muscle relaxants that are not useful in the treatment of malignant hyperthermia. Source: Stern - 2004

1011.The most common surgical option for trigeminal neuralgia is: A. Stereotactic radiosurgery B. Gangliolysis C. Microvascular decompression of the trigeminal nerve D. Peripheral neurectomy E. Intracranial Trigeminal Neurectony
1011. Answer: C Explanation: The artery causing compression over the trigeminal nerve as it leaves the Pons is repositioned. If it’s a vein, it is coagulated. This surgery has an 85% success rate over 5 years. The surgical approach is by a suboccipital craniectomy. Stereotactic radiosurgery is performed using a gamma knife or a linear accelerator. A radiosurgical lesion is placed in the trigeminal root. The short term results are good. Gangliolysis is performed by positioning a percutaneous needle through the foramen ovale and into the rootlets behind the gasserian ganglion. The lesion is made either by radiofrequency destruction of the posterior roots, infl ation of a balloon in the Meckel’s cave or injection of glycerol into the cistern of the trigeminal ganglion. This procedure is indicated in debilitated patients who cannot tolerate major surgical procedures. Peripheral neurectomy is performed by repeat avulsions of the peripheral branches of the trigeminal nerve. This is sometime performed if patients fail treatment with Gangliolysis.

The sensory examination showed hypoesthesia in the lateral forearm. What is the most likely involvement of disc herniation and nerve root in this patient? A. C6/7 disc herniation with C7 nerve root involvement B. C7/T1 disc herniation with C8 nerve root involvement C. T1/T2 disc herniation with T1 nerve root involvement D. C4/5 disc herniation with C5 nerve root involvement E. C5/6 disc herniation with C6 nerve root involvement
1023. Answer: E Explanation: Wrist extensors are supplied by C6 and partially by C7. The biceps has both C5 and C6 innervation. Under the radial extensors, extensor carpi radialis, longus and brevis, is supplied by radial nerve C6 in contrast to ulnar extensors supplied by extensor carpi ulnaris and C7 innervation. C6 supplies sensation to the lateral forearm, the thumb,the index fi nger, and one half of the middle fi nger. To remember the C6 sensory distribution more easily, form the number 6 with your thumb, index, and middle fi ngers by pinching your thumb and index fi nger together while extending your middle fi nger.

1024. Answer: E Explanation: Intermittent Horner syndrome is most likely to occur with cluster, due to distention of the internal carotid artery wall as the sympathetic fi bers travel within the carotid artery.Horner syndrome is partial, with ptosis and miosis but no anhidrosis.Other autonomic signs are present (perspiration, tachycardia, bradycardia, lacrimation), which suggests autonomic instability.

``` 1025. Spasticity can be caused by sectioning A. The corticospinal fi bers B. The vestibulospinal fi bers C. The afferent fi bers D. The corticoreticular fi bers E. The reticulospinal fi bers ```
1025. Answer: D Explanation: (Guyton, pp 639-640.) Spasticity results from over activity of the alpha motoneurons innervating the skeletal musculature. Under normal circumstances, these alpha motoneurons are tonically stimulated by reticulospinal and vestibulospinal fi bers originating in the brainstem. These brainstem fi bers are normally inhibited by fi bers originating in the cortex. Cutting the cortical fi bers releases the brainstem fi bers from inhibition and results in spasticity Cutting the fi bers from the reticular formation, vestibular nuclei, or the Ia afferents will reduce the spasticity.

1026. A patient presents with pain and paresthesia in the left leg. The distribution of the pain-running down the medial aspect of the leg and the medial side of the foot and including the great toe-is suggestive of a herniated intervertebral disk. The most likely location of herniation is: A. L3-L 4 intervertebral disk B. L4-L5 intervertebral disk C. L5-S1 intervertebral disk D. S1-S2 intervertebral disk E. Insuffi cient data to determine
1026. Answer: A Explanation: (April, 3/e, pp 133, 140.) The deep incisure in the inferior border of the pedicle ensures that the spinal nerve associated with that vertebra will exit through the intervertebral foramen well above the intervertebral disk so that it will not be affected by a herniation at that level. However, a posterolateral herniation (the usual direction) will impinge on the next lower nerve as it courses toward its associated intervertebral foramen. In this case, pain was distributed along the medial side of the leg and foot as far as the great toe-the distribution of the saphenous branch of the femoral nerve (L4). Herniation of the third lumbar intervertebral disk between vertebral bodies L3-L4 would affect nerve L4. Source: Klein RM and McKenzie JC 2002.

1027. A middle aged man is administered morphine via patient-controlled analgesia (PCA) pump after a left total hip arthroplasty. The pump is programmed to deliver a maximum dose of 2 mg every 15 minutes (lockout time) as needed for patient comfort. The total maximum dose that can be delivered in 4 hours is 30 mg. On the fi rst day the patient receives 15 doses every 4 hours by pressing the delivery button every 15 to 18 minutes. How should his pain control be further managed? A. Discontinue the PCA pump and administer intramuscular morphine B. Increase the lockout time from 15 to 25 minutes C. Change the analgesic from morphine to fentanyl D. Increase the dose to 3mg every 15 minutes as needed up to a total maximum dose of 40 mg every 4 hours E. Make no changes
1027. Answer: D Explanation: Frequent dosing by a patient receiving postoperative analgesia through a PCA pump suggests the need to increase the magnitude of the dose. A patient also should be given a suffi cient loading dose of narcotic before initiative therapy with a PCA pump.

1030. Answer: D Explanation: The transverse (palmar) carpal ligament bounds the carpal tunnel, at its volar surface. This ligament is attached to the tubercle of the scaphoid and trapezium on the radial side and the hamate on the ulnar side. This canal transmits the median nerve, but not its palmar branch. Additionally, the canal transmits the fl exor digitorum superfi cialis x4, fl exor digitorum profundus x4, and fl exor policis longus.

1035. A 31-year-old man develops left ankle pain after stepping off a curb. He treated the injury with ice overnight but the next day cannot walk due to the pain. On examination of the ankle, you notice that it is swollen and ecchymotic. The anterior and lateral aspects of the ankle are tender to palpation. Inversion of the ankle is painful. Which of the following is the most likely diagnosis? A. Ankle sprain B. Rupture of the Achilles tendon C. Metatarsal stress fracture D. Plantar fasciitis E. Tarsal tunnel syndrome
1035. Answer: A Explanation: (Tierney, 42/e, pp 801-802.) Ligament injuries of the ankle are common and may occur in sports requiring jumping and running. These injuries occur when the foot twists as it lands on the ground and can even be a consequence of walking on uneven ground. The medial ligament is typically injured with eversion and the lateral ligament (the ligament most commonly affected by injuries) with inversion. The lateral ligament is composed of three parts: the anterior talofi bular ligament, the calcaneofi bular ligament, and the posterior talofi bular ligament. The injured ligament is tender to palpation, ecchymotic, and swollen. Metatarsal stress fractures (march fractures) occur after long periods of running or walking; pain is typically in the middle of the forefoot. Rupture of the Achilles tendon may occur with running and jumping. It causes a palpable defect, swelling, and tenderness over the tendon. The Thompson test is positive (patient lies with knee fl exed to 90° and the examiner squeezes the calf muscle; if the Achilles tendon is ruptured, the foot will not move, but if the tendon is intact, the foot will plantarfl ex). Plantar fasciitis causes pain over the medial aspect of the plantar fascia. It usually starts slowly and is of long duration. The windlass test is positive (pain increases with ankle and great toe dorsifl exion). Tarsal tunnel syndrome occurs with entrapment of the posterior tibial nerve. The patient complains of burning and numbness that extends from the sole of the foot and toes to the medial malleolus.

``` 1037. What is the neurotransmitter involved in migraine ? A. Dopamine B. Acetylcholine C. Serotonin D. GABA E. Norepinephrine ```
1037. Answer: C Explanation: It is believed that there is unstable serotonin neurotransmission in migraine, with increased raphe neuronal fi ring rates. During acute migraine attack, platelet serotonin levels fall and urinary serotonin increases. Serotonin transmission abnormalities in the gastrointestinal system explain prominent GI symptoms, and affective-mood disturbances are also due to unstable CNS serotonin changes.

1041. A young woman has a diagnosis of irritable bowel syndrome. She has a constitutional predisposition to respond physiologically to a situation in a particular way, has inadequate homeostatic restraints, and develops symptoms when exposed to activating situations. This etiological sequence in a psychophysiologic disorder follows the A. Specifi c-attitudes theory B. Diathesis-stress model C. Weak organ/system theory D. Individual response stereotypes E. Specifi c-response pattern model
1041. Answer: B Explanation: (Baum, pp 211-220.) · Psychophysiologic disorders were formerly referred to as psychosomatic illnesses. They are characterized by physical symptoms from organs of the body that have become dysfunctional through an interaction between psychological, biologic (including genetic), and sociocultural factors. · The most common psychophysiologic disorders are hypertension, bronchial asthma, dysmenorrhea, headache, neurodermatitis, peptic ulcer, irritable bowel syndrome, rheumatic arthritis, and ulcerative colitis. Diabetes, along with many other diseases, has a strong psychological component, but is not considered to be a psychophysiologic disorder. Source: Ebert 2004

1042. Which of the following approaches provides the most consistent blockade of the brachial plexus? A. Interscalene B. Supraclavicular C. Infraclavicular D. Axillary E. Suprascapular
1042. Answer: B Explanation: (Raj, Pain Medicine Review, pages 236-238) A. The interscalene targets the roots and may miss C8 and even, C7. B. The upper, middle, and lower trunks of the brachial plexus are predictably pass over the fi rst rib, between the insertion of the anterior and middle scalene muscles onthe fi rst rib. This is the most compact area of the brachial plexus and hence, the supraclavicular approach is the most effi cient way to block the brachial plexus. C. The infraclavicular approach may block the plexus at the level of the musculocutaneous and axillary nerves high in the axilla: anesthesia is obtained from the shoulder to the hand. However, since the block is at the level of the formation of the musculocutaneous and axillary, typically inferior and lateral to the coracoid process, more cephalad and proximal neural branches may be missed. Since the brachial plexus is less compact at this level and since a neural stimulator is required, less consistent blockade may occur. D. The axillary approach is indicated for surgery of the forearm and hand. It primarily targets the radial, median, and ulnar nerves, but not the axilla nor musculocutaneous nerves. It does not reliably provide analgesia for procedures above the elbow. E. The suprascapular nerve block relieves afferent pain from the shoulder joint and causes motor blockade of the supra- and infraspinatus muscles. There is no suprscapular approach for brachial plexus blocks. Source: Shah RV, Board Review 2003

``` 1045. Extensive cord infarction caused by foraminal injection would most likely result from injection of particulate steroid directly into which of the following arteries: A. Posterior radicular artery B. Anterior radicular artery C. Anterior segmental medullary artery D. Anterior spinal artery E. Posterior spinal artery ```
1045. Answer: C Explanation: Reference: Gray’s Anatomy, Thirteenth American Edition. Pages 964-971. Data from cases of extensive cord infarction after transforaminal injection of particulate steroid suggest that large portions of the cervical spinal cord can be infarcted by intra-arterial injection of particulate steroid into the anterior segmental medullary artery. The anterior segmental medullary arteries course through various neural foramina to connect to the anterior spinal artery which in turn delivers blood to the cord parenchyma. Injection of particulate steroid into this artery can disrupt spinal cord blood fl ow by occluding end-arterioles with microcrystal particles. These particles may exceed 20 microns in diameter and, with intravascular coalescence and/or precipitation, much larger particles may be formed. The anterior and posterior radicular arteries supply blood to the anterior and posterior spinal nerve roots at every spinal level bilaterally. These arteries do not supply blood to large portions of the spinal cord parenchyma. The anterior and posterior spinal arteries are deep within the central spinal canal and are not directly accessible by intraforaminal injection. Source: Schultz D, Board Review 2004

``` 1046. A person with which of the following mental disorders is most apt to seek medical help? A. Major depressive disorder B. Bipolar depressive disorder C. Dysthymic disorder D. Anxiety disorder E. Obsessive-compulsive disorder ```
1046. Answer: D Explanation: (Fauci, pp 2486-2490.) Anxiety symptoms are very common in both medically ill patients and those otherwise well. Five to 20% of inpatients have anxiety symptoms and 5 to 20% of general medical outpatients suffer from anxiety states. Patients with anxiety disorders are more likely to seek help from general physicians and to use emergency room services than are patients with other types of mental disorders. Furthermore, it has been documented that over the past 15 years, antianxiety medications have been the most frequently prescribed medication in the U.S. Also, primary physicians write over 80% of these prescriptions. In terms of other mental disorders, over 5% of the U.S. population suffers from mood disorders-including major depressive, bipolar, and dysthymic-yet they are less apt to seek medical help. Panic disorders occur in 1 to 2% of the population and 29% of these persons seek help from emergency room services. Obsessive-compulsive disorder usually begins in adolescence or young adulthood, but is not often recognized by general physicians. Help may not be sought because of the private nature of the disorder

1047. Patients who have somatization disorder are diagnosed on the basis of their A. Having unexplained symptoms that persist after treatment B. Experiencing symptoms in multiple organ systems C. Having a history of past and present illnesses that have not responded to self-treatment D. Having a specifi c number of medically unexplained symptoms E. Demonstrating positive test results for several chronic illnesses at the same time
1047. Answer: D Explanation: (Sierles, pp 266-269. Ebert, pp 366-377.) Between 0.5 and 3% of the population experience many vague and fl uctuating symptoms in multiple organsystems over time. They are explored with medical tests and treated, but are never cured. The unexplained symptoms can start in childhood, are usually diagnosed by 25 years of age, and can continue many years undiagnosed. The Diagnostic and Statistical Manual of Mental Disorders, 4/e (DSM-IV) lists many relevant symptoms from multiple organ and psychological systems. A diagnosis of somatization disorder (SD) can be made if a patient experiences the following medically unexplained symptoms: 4 pain symptoms, 2 gastrointestinal symptoms, 1 sexual symptom, 1 psychoneurologic symptom, and/or if the physical complaints and social or occupational impairments are in excess of the expected. This “lumping” of so many related and unrelated symptoms into one disorder has resulted in some disagreement among clinicians who argue that it is label-oriented and does not contribute to an understanding of causality or treatment. Nevertheless, it is a serious disorder that should receive more recognition and research. The symptoms have to concern the patient enough to take prescribed medication, to change behavior (e.g., to miss work), or to consult a physician. Episodes of symptoms, sometimes intense, typically last 6 to 9 months, with less intense, but continuing symptoms for 9 to 12 months. Generally, SD is a lifelong condition, and patients with SD consider themselves to be sick. Eighty-six percent report that their symptoms are so disabling that their work is limited. Seventy-fi ve percent are not employed full-time, as compared with 33% of patients with other psychiatric diagnosis. When compared with the general population, they are more likely to visit doctors, be hospitalized, and receive unnecessary surgery. Eighty to 90% report past depression, 27% have hysterectomies for non-cancerrelated causes, 17 to 25% have irritable bowel syndrome, and 12% experience chronic pain. SD patients are also at increased risk for panic disorder, phobias, general anxiety disorder, obsessive-compulsive disorder, and alcoholism; 47% have coexisting personality disorders (avoidant, paranoid, and histrionic). Female-tomale ratios between 2: 1 and 20: 1 have been reported. There is often an inability to identify and articulate their emotions, they have diffi culty habituating to stimuli, and they receive positive reinforcement from medical attention.No treatment cures SD,but patients can be taught about SD and taught a relaxation procedure. Patients should establish regular doctor visits (versus responding to symptoms). Physicians should direct I conversation to the patients personal life and a healthy lifestyle, while deemphasizing symptoms and praising tolerance for symptoms. Source: Ebert 2004

1048. A 55-year old male presents himself with sudden pain and loss of function of the right shoulder fi ve days ago. Symptoms started after intense activity. The patient was holding the shoulder away from the body in 30° to 40° adduction. The pain was presented anteriorly. There was no history of recent injury. Aspirin helped his pain temporarily. X-were normal. The most likely diagnosis is: A. Subacromial bursitis B. Subcoracoid bursitis C. Calcifi c tendonitis D. Acromioclavicular joint arthritis E. Branchial neuritis
1048. Answer: A Explanation: Subacromial bursitis may occur as a primary disorder after a blow to the shoulder, but if, it most frequently occurs secondary to degenerative lesions of the rotator cuff and is part of the continuum of the many rotator cuff disorders. It may be viewed as a separate yet related pathologic condition to calcifi c tendonitis. Most of the body’s bursae exists in or around the shoulder complex, and they are listed up to 12. The most commonly present bursae locations include the subacromial and subdeltoid. The subdeltoid and subacromial bursae are really one but are separately named according to their adjacent anatomic structures. Bursitis will have a swift onset of extremely severe shoulder pain with dramatic tenderness localized to the insertion of the deltoid at the upper middle third of the anterolateral proximal arm. This is in contrast to more diffuse involvement found with impingement of the supraspinatus or biceps tendon or pain found adjacent to the coracoid process at the medial aspect of the shoulder in subcoracoid bursitis. The patient maintains the shoulder in an adducted position,which keeps the painful lesion away from the acromial undersurface. Elevation is hindered, abduction more so than forward fl exion, and a painful arc between 50° and 130° is present whether the movement is active or passive. On palpation, the physician will fi nd exquisite local tenderness over the subacromial bursae, which may feel thickened as compared to the contralateral shoulder. Tenderness may also extend as far down as the bicipital groove. Tests for supraspinatus tendonitis and impingement will be positive in this condition. Source: Saidoff DC, McDonough AL.

1050. Examination of a patient’s visual fi elds reveals complete blindness in the left eye. Ophthalmoscopic examination is normal. Which of the following lesions is most likely causing this abnormality? A. A lesion between the optic chiasm and the lateral geniculate body B. A lesion between the retina and the optic chiasm C. A lesion between the lateral geniculate body and the visual cortex D. A lesion at the medial longitudinal fasciculus E. A lesion of one occipital lobe
1050. Answer: B Explanation: (Seidel, 5/e, p 311.) When defects are detected in only one eye, the lesion must be anterior to the optic chiasm. Lesions at the optic chiasm produce a bitemporal hemianopsia because this is where the nasal retinal fi bers decussate. The medial longitudinal fasciculus (MLF) is involved with extraocular muscle contraction; a lesion to the MLF bilaterally will not allow either eye to look medially. Lesions between the geniculate body and the visual conex produce a contralateral upper homonymous quadrantanopsia. A lesion in the visual cortex (occipital lobe) produces similar defects in each eye. Bilateral lesions of the occipital lobes result in complete loss of vision, but pupillary refl exes (fi bers end in the midbrain) and extraocular muscle movements remain intact.

She has pain free intervals between attacks. She is unable to put on any makeup because the slightest touch of a brush sets of her pain. All of the following would be an appropriate initial medication EXCEPT: A. Baclofen B. Carbamazepine C. Lamotrigine D. Carisoprodol E. Lidocaine 5% patch
1051. Answer: D Explanation: The treatment of trigeminal neuralgia fi rst pharmacological and if this fails then surgical options are explored. Pharmacological management consists of carbamazepine, phenytoin, gabapentin, lamotrigine, baclofen.Carbamazepine is the initial drug of choice and is generally started as a single dose of 100mg daily. It is then increased every 2 or 3 days by 100mg until good relief is obtained. A common dose is at least 200mg per day.The common side effects of carbamazepine are agranulocytosis, dizziness and sedation. Carisoprodol is a muscle relaxant and has no role in the management of trigeminal neuralgia. The pathology of trigeminal neuralgia is usually at the ganglion and no benefi t is obtained using local anesthetics. Source: Chopra P, 2004

1053. The following is characteristic of migraine with aura: A. Fortifi cation spectra. B. Headache preceding motor weakness. C. Headache preceding aphasia. D. Amaurosis fugax and scintillating scotoma. E. Headache precipitated by emotional stress.
1053. Answer: A Explanation: Fortifi cation spectra are the most characteristic visual disturbance of migraine. These consist of C-shaped serrated zig-zag arcs followed by scotoma (area of blindness). Visual disturbance recedes before headache develops. When headache precedes neurological disturbance, consider nonmigraine disorders. Amaurosis fugax is visual loss in one eye only and suggests severe carotid stenosis. Emotional stress may precipitate migraine. Migraine usually develops not at peak stress but during a period of relaxation (“let-down”). This is contrasted with tension headache, which correlates directly with severity of emotional stress.

1060. Answer: A Explanation: Immediately following spinal cord injury, there is electrical-chemical change which enhances inhibitory neurotransmission such that all refl exes are absent. Later, refl exes become hyperrefl exive. In adults, spine or brain traumatic injuries do not cause blood loss. With traumatic spinal cord injury, autonomic function occurs immediately, and these patients require catheterization. Source: Neurology for the Psychiatry specialty Board Review By Leon A.

1061. Choose the accurate statement about Visual Analogue Scale. A. A Visual Analogue Scale consists of a list of adjectives describing different levels of pain intensity. B. A Visual AnalogueScale consists of a line, usually 10 cm long, whose ends are labeled as the extremes of pain (no pain to pain as bad as it could be). C. A Visual Analogue Scale involves asking patients to rate their pain from 0 to 10 on an 11 point scale. D. A Visual Analogue Scale employs pain intensity measure which is determined by photographs or line drawings that illustrate facial expressions of persons. E. A Visual Analogue Scale consists of pain intensity which describes from faint to very intense.
1061. Answer: B Explanation: A. A verbal rating scale consists of a list of adjectives describing different levels of pain intensity. An adequate VRS of pain intensity should include adjectives that refl ect the extremes of this dimension from no pain to extremely intense pain and suffi cient additional adjectives to capture the graduations of pain intensity that may be experienced. B. A Visual Analogue Pain Scale consist of a line, usually 10 cm long, whose ends are labeled as the extremes of pain (e.g., “no pain” to “pain as bad as it could be”). A VAS may have specifi c points along the line that are labeled with intensity-denoting adjectives or numbers. Such a scale is called a graphic rating scale. Patients are asked to indicate which point along the line best represents their pain intensity. The distance from the no pain end to the mark made by the patient is that patient’s pain intensity score. C. A numeric rating scale involves asking patients to rate their pain from 0 to 10 (11 point scale), from 0 to 20 (21 point scale), or from 0 to 100 (101 point scale), with the understanding that the 0 represents 1 end of the pain intensity continuum with no pain while 10, 20, or 100 represents the other extreme of pain intensity. Verbal rating scales do not require paper and pencil. The patient is simply asked to verbally state his or her pain intensity on a 0 to 10 or one of the other scales. Nonetheless, a number of paper and pencil numeric rating scales exist. The validity of numeric pain rating scales has been well documented. They demonstrate positive and signifi cant correlations with other measures of pain intensity. D. Picture or face scales employ photographs or line drawings that illustrate facial expressions of persons experiencing different levels of pain severity. The patients are asked to indicate which one of the illustrations best represents their pain experience. Each face has a number representing the rank order of pain illustrated, and the number associated with the picture chosen by the patient represents that individual’s pain intensity score. E. Descriptor Differential Scale of pain intensity consists of a list of adjectives describing different levels of pain intensity. Patients are asked to rate the intensity of their pain as being more or less than each word on the list. If their experienced pain is greater than that described by the word, they place a check mark on the right of the word in proportion to how much greater their pain is. The DDS-1 has many strengths because it is a multiple-item measure, it is possible to assess the internal consistency of the scale, and this consistency appears to be very high. Descriptor Differential Scale of pain intensity DDS-1 consists of the words faint, moderate, barely strong, intense, weak, strong, very mild, extremely intense, very weak, slightly intense, very intense, and mild.

``` 1073. Injection of local anesthetic into the interspace between the 3rd and 4th toes may provide relief of which condition A. Morton’s neuroma B. Metarsalgia C. Plantar Fasciitis D. Painful heel spur E. Tarsal Tunnel Sundrome ```
1073. Answer: A Explanation: ( Raj, {Practical Mgmt of Pain, 3rd Ed., page 355-6, 371) A. Morton’s neuroma is the most common form of interdigital neuritis. It typically occurs between the third and fourth toes and rarely between the second and third toes. Pain can be produced between the metatarsal heads, which differentiates this condition from metatarsalgia, in which pain is elicited with pressure against the plantar foot under the metatarsal heads. B. Pain along the plantar surface of the metatarsal heads causes weight-bearing discomfort with each step and can be replicated with manual compression. About 80% of the weight is borne by the fi rst metatarsal head, but in pronation, weight is shifted over the second and third toes and painful repetitive trauma can accumulate. Pain is typically increased in combined pronation and eversion, and this gait C. Plantar fasciitis is commonly found in those who must stand on hard fl oors for long periods of time and is an infl ammation of tendon and fascia and as they insert into the calcaneal periosteum.Bone growth in the direction of pull is frequently found as a calcaneal spur. The examiner can elicit pain with plantar compression over the anterior calcaneus, but pain may radiate along the plantar fascia. D. Painful heel syndrome is often diagnosed in morbidly overweight people or those who stand or walk excessively.Degeneration of the normal heel compression allows injury to weight-bearing surfaces of the calcaneus. Frequently, symptoms are increased in the morning or after a prolonged rest. Examination fi ndings are similar to those in plantar fasciitis, but pain tends to be posterior and localized to the plantar calcaneus. E. The posterior tibial nerve is derived from L4 through S3 roots and may be compressed in the tarsal tunnel.Nerve conduction studies show prolongation of the distal motor and sensory latency of the tibial nerve.There may be EMG changes in the appropriate foot muscles. This syndrome is relatively uncommon. Source: Shah RV, Board Review 2004

1074. Answer: B Explanation:Reference: Hardman, p 444. This patient ate tyramine-rich foods while taking an MAOIand went into hypertensive crisis. Tyramine causes release of stored catecholamines from presynaptic terminals, which can cause hypertension, headache, tachycardia, cardiac arrhymias, nausea, and stroke. In patients who do not take MAOIs,tyramine is inactivated in the gut by MAO, and patients taking MAOIs must be warned about the dangers of eating tyramine-rich foods. Source: Stern - 2004

1075. Which of the following is the most important disadvantage of interscalene brachial plexus block compared with other approaches? A. Frequent sparing of the musculocutaneous nerve B. High incidence of pneumothorax C. Not suitable for operations on the shoulder D. Large volumes of local anesthetics required E. Frequent sparing of the ulnar nerve
1075. Answer: E Explanation: The major disadvantage of the interscalene block for hand and forearm surgery is that blockade of the inferior trunk (C8-T1) is often incomplete. Supplementation of the ulnar nerve is often required. The risk of pneumothorax is quite low, but blockade of the ipsilateral phrenic nerve occurs in up to 100% of blocks. This can cause respiratory compromise in patients with signifi cant lung disease.

1077. The following statement is false regarding local anesthetic toxicity: A. Hyperventilation of a patient with a suspected overdose of local anesthetic will make seizures less likely. B. Lidocaine overdose causes seizures before cardiac depression. C. Toxic dose for direct intravascular injection of lidocaine is 300mg without epinephrine and 500mg when epinephrine is added. D. Intravenous benzodiazepines are recommended to treat local anesthetic-induced seizures E. Cardiac arrest from bupivacaine overdose is exceedingly diffi cult to treat and prolonged resuscitation with large doses of epinephrine may be required.
1077. Answer: C Explanation: References: Neural Blockade, Cousins and Bridenbaugh, Second Edition, Chapter 22 Complications of Local Anesthetic Neural Blockade, pp. 695-718. Waldman, Interventional Pain Management, Second Edition; Chapter 16 Local Anesthetics in Clinical Practice, pp. 214-218 Elevation of pCO2 and acidosis tend to increase the toxic effects of local anesthetics by the following mechanisms: Elevated pCO2 causes cerebral vasodilation, delivering more local anesthetic to the brain Decrease in intracellular pH will convert more local anesthetic from the inactive base form to the cationic form which is active on the nerve membranes. Hypercarbia and acidosis decrease protein binding of local anesthetics increasing the portion of free drug available Conversely, decreases in pCO2 and elevations in pH tend to elevate the seizure threshold for local anesthetics by the same mechanisms. Lidocaine will almost invariable cause CNS effects prior to causing cardiac toxicity. First the patient may complain of dizziness, tinnitus and diffi culty focusing eyes. Increasing toxicity causes muscle twitching and tremors involving the face and distal extremities which progresses to grand mal seizures. Cardiac arrythmias occur late and only with massive overdose. The maximum dose for lidocaine soft tissue infi ltration is 300mg without epinephrine and 500mg when epinephrine is added. This does not imply that 300mg can be given directly IV as a bolus dose. The toxic dose for direct intravenous injection of any local anesthetic is much lower than the toxic dose for tissue infi ltration. For instance, the tissue infi ltration maximum dose for bupivacaine is approximately 200mg whereas doses as small as 50mg have caused cardiac toxicity when administered directly IV. Bupivacaine has a much higher potential to cause lifethreatening cardiac arrhythmias than lidocaine. Whereas lidocaine is a fast-in/fast-out calcium channel blocker that reaches steady state block in one to two heartbeats. In contrast, bupivacaine is a fast-in/slow-out blocker manifesting a blocking action that increases with successive beats and with faster rates creating the potential for malignant re-entrant cardiac arrhythmias. Resuscitation from bupivacaine cardiac toxicity is diffi cult and may require prolonged efforts with high doses of epinephrine. There is no specifi c antidote or reversal agent for bupivacaine overdose. Benzodiazepenes increase the seizure threshold in the brain and are the treatment of choice for local anesthetic induced seizures. Source: Schultz D, Board Review 2004

1081. Answer: D Explanation: (Carlson, pp 259-267.) · The human research on sleep has demonstrated that after a few days of sleep deprivation people report perceptual distortions or, in a few cases, even hallucinations. These studies have documented statements such as “the fl oor seems wavy” or “steam seems to be rising from the fl oor,” indicating that sleep deprivation affects cerebral functioning. · Sleepiness can occur even without any activity and sleep deprivation does not appear to interfere with the ability to perform physical exercise. Likewise, there is no evidence of a physiologic stress response to sleep deprivation, indicated by little change in blood levels of cortisol and epinephrine.Sleep does appear to be necessary for the brain to function normally. · After a period of sleep deprivation a rebound phenomenon does occur.

1084. Answer: C Explanation: (Raj, Practical Mgmt of Pain 3rd Ed. Page 802, Raj, Pain Medicine Review, 2nd Ed., page 314) This is not a benign procedure. Make sure you understand the difference between this procedure, dorsal rhizotomy, and dorsal ganglionectomy. In this procedure, one is targeting a mixed nerve. Spinal nerve more accurately more describes the entity referred to as a selective nerve root. The term, ‘selective nerve root’ should not be used since it lacks anatomic precision. Nonetheless, it may still be used in the exam. Hence, lesioning the spinal nerve can cause motor and sensory dysfunction. It should be used to treat pain related to spasticity due to central nervous system damage. It should be avoided in non-cancer conditions. Sciatic nerve transaction may lead to deafferentation pain and central sensitization. Denervation of those spinal nerves supplying the sciatic nerve may worsen this pain condition. Additionally, sciatic nerve transaction will not cause spasticity. Source: Schultz D, Board Review 2004

1086. Which of the following is among the most useful procedures for the relief of unilateral cancer pain below the C5 dermatome? A. Midline myelotomy B. Lissauer tractotomy C. Percutaneous C1-2 radiofrequency unilateral cordotomy D. Post central gyrectomy E. Bilateral high cervical cordotomy performed at the same time
1086. Answer: C Explanation: (Raj, Pain Review, 2nd Ed., page 313) Lissauer tractotomy is the goal of the dorsal root entry zone (DREZ) procedure…but all dorsal horn lamina (I-V) may be affected. The DREZ lesion is classically indicated for central nervous system damage related pain: brachial plexus avulsion, stump pain, spinal cord injury pain. Midline or commissural myelotomy sections those midline fi bers just dorsal to the central canal of the spinal cord. The original intent was to lesion crossing spinothalamic neurons, which would eliminate pain, but preserve sensory function. However, pain relief extended caudally, without demonstrable caudal analgesia. This lead several investigators to postulate several alternate pain pathways. A multisynaptic short tract afferent pathway or an anterior tract located in between the posterior columns were proposed. The latter mediate pelvic and epigastric visceral pain. Nonetheless, myelotomy is indicated for bilateral pelvic and perineal pain of malignant origin. Post-central gyrectomy is not a primary neurosurgical procedure for pain relief and is used for central pain syndromes: thalamic or phantom pain. The post-central gyrus is the principal cortical area for the integration of sensory information. Bilateral high cervical cordotomy may be responsible for Ondine’s curse (sleep induced apnea) and is contraindicated unless performed in a staged fashion. Unilateral percutaneous cordotomy is among the most useful procedures for unilateral cancer pain below C5. It targets the spinothalamic tract. Radiofrequency energy is used. Electrical stimulation (sensory to obtain a feeling of warmth or coolness on the contralateral side and motor to obtain ipsilateral cervical muscles; ipsilateral contraction of muscles below the neck implies the probe is in the corticospinal tract) is used to identify the lesion target Source: Schultz D, Board Review 2004

1097. Answer: C Explanation: A. Ataxic gait is often characterized by clumsiness; when steps are taken, the advancing foot is lifted high.The foot is then brought down in a slapping or stamping manner. B. Parkinsonian gait is noted for the forward stoop of the head and shoulders, with arms slightly abducted and forearms partially fl exed; there is decreased arm swing as the feet shuffle. C. Spastic hemiplegic gait is the result of spasticity of the involved limb. The limb is moved forward by abduction and circumduction. D. Steppage gait occurs with footdrop (paralysis of the peroneal nerve); the affected foot is raised higher than normal to prevent dragging of the toe. Bilateral footdrop results in a gait resembling that of a high-stepping horse. E. Spastic diplegia gait or scissor gait occurs with extrapyramidal disorders. The patient uses short steps and drags the foot; the legs are extended and stiff and cross on each other. Source: Seidel, Sle, pp 791-792.

1102. A 45-year old, slim, heavy smoker, presents with low back pain that radiates into right buttock and to the leg slightly below the knee. The pain started somewhat suddenly for this episode but he suffered with chronic pain on and off for 20 years. Most recently, the pain was associated after driving continuously for 8 hours in a pickup truck. The physical examination was grossly normal except for tenderness in the lumbar spine and exacerbation of pain with hyperextension. Patient brought plain x-ray picture fi lms with him and refuses to undergo any further investigations. Based on the plain x-ray films shown below (pg.180), your radiologic diagnosis is as follows: A. Grade I spondylolisthesis and spondylolysis of L5 on S1 B. Grade I spondylolisthesis of L5 on S1 with bilateral pars defects C. Grade II spondylolysis of L5 on S1 D. Grade III spondylolisthesis of L5 on S1 with bilateral pars defects E. Extensive facet joint arthritis with spinal stenosis
1102. Answer: E Explanation: (Tierney, 42/e, pp 797-798.) The patient most likely has carpal tunnel syndrome (CTS), which is compression of the median nerve by the transverse volar ligament of the wrist. Patients complain of pain and paresthesias of the ‘hand and weakness and atrophy of the thenar muscles. The Tinel sign (tapping the median nerve at the wrist) and Phalen sign (forced wrist fl exion) intensify the symptoms. Risk factors for CTS include pregnancy, diabetes mellitus, hypothyroidism, rheumatoid arthritis, amyloid infi ltration as seen in patients with multiple myeloma, acromegaly, and repetitive trauma. Ulnar nerve paralysis causes a claw hand deformity Radial nerve palsy causes wristdrop. Erb- Duchenne palsy (C5-C6) causes weakness of the shoulder and elbow and results in the waiter’s tip position (arm dangles at the side with palm in a backward position with fi ngers fl exed). Klumpke-Dejerine palsy (C8-Tl) is a triad of claw hand deformity, absent triceps refl ex, and Horner syndrome. Patients with cervical radiculopathy (C6 or C7 root) complain of neck pain that radiates to the arm (radicular pain), dermatomal sensory loss, and decreased refl exes.

Left L3/4 disc herniation with pressure on L4 nerve root E. Left L4/5 disc herniation with pressure on L5 nerve root
1105. Answer: E Explanation: (Raj, Pain Medicine Review, 2nd Ed., page 236-238) An interscalene block is performed with the patient supine and their head rotated away from the operator. The C6 level is palpated by identifying the cricoid cartilage. The non-dominant hand’s index fi nger is used to gently palpate the posterior border of the sternocleidomastoid muscle. The fi nger is moved further posteriorly to identify the groove between the anterior and middle scalenii. The patient may be asked to deep breathly to accentuate this groove. The ext. jugular vein may run across this location. A 22g needle is advanced medial, posterior, and slightly caudad (perpendicular to skin). Paresthesias should be elicited in the shoulder, or hand is obtained. 40-50 cc of local may be instilled incrementally. The block is performed at the level of the cervical roots and is most likely to miss the C8 spinal nerve. Thus, one may get incomplete analgesia of the ulnar aspect of the hand. All the others are covered by the C5, C6 areas primarily. Source: Shah RV, Board Review 2003

1109. A 42 year-old man develops excruciating pain extending from his buttocks to the dorsum of his foot. Which of the following would confi rm the presence of a disc protrusion? 1. The Lasegue’s sign 2. Thomas test 3. Milgram Test 4. Fabere Test
1109. Answer: B (1 & 3) Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed., page 350 and 358) 1. Straight Leg Raising Test: Lasègue’s Sign: This maneuver can test for sciatic irritation (pain radiating to the ankle of the tested leg),but sciatic nerve irritation must be differentiated from hamstring tightness (pain descending the posterior thigh only). The patient lies supine, with the examiner stabilizing the heel in one palm and helping to maintain knee extension with the other. Elevation is performed to 70 to 90 degrees at the hip, and radiating pain to the ankle confi rms the test. 2. Thomas Test.The Thomas test evaluates fl exion contracture of the hip. The patient lies supine with the pelvis level, allowing a T to form between the vertebral spine and the pelvic brim. The hip is passively fl exed with the examiner’s other hand beneath the small of the back, feeling the point where the lumbar curve is lost. The thigh is then placed against the abdominal wall. The other leg is fl exed in similar fashion and allowed to descend to the examination table. If compensation is attempted by arching 3. MILGRAM TEST: The patient lies supine and attempts to hold the heels about 2 inches off the table for 30 seconds. Intrathecal pressure is elevated, and if a mass lesion or herniated disk is present, the patient lowers the affected side to the table. 4. Fabere (Flexion-Abduction-External Rotation [- Extension]) Test: This maneuver tests for sacroiliac or hip pathology. The patient is supine with the knee and hip fl exed and the heel on the opposite knee, allowing the femur to lower to the examination table. This position results in hip abduction and external rotation. Groin pain suggests hip pathology, and sacroiliac pain suggests a problem with this joint Source: Shah RV, Board Review 2004

1112. Which statements are false regarding spinal injection and bleeding complications: 1. Aspirin and other NSAIDS, in and of themselves, do not signifi cantly increase the risk of epidural hematoma and need not be discontinued prior to spinal injection. 2. Spinal injection may be safely performed on a patient who has been off Coumadin for 4 days and has an INR of 1.4 3. Cox 2 inhibitors such as Celebrex and Vioxx do not inhibit platelets and do not affect coagulation. 4. Bleeding time predicts hemostatic compromise in patients taking anti-platelet drugs.
1112. Answer: D (4 Only) Explanation: Reference: Horlocker, et. Al. Regional Anesthesia in the Anticoagulated Patient: Defi ning the Risks (The Second ASRA Consensus Conference on Neuraxial Anesthesia and Anticoagulation) At the 1998 Consensus Conference on Neuraxial Anesthesia and Anticoagulation, it was concluded that NSAIDs, in and of themselves, did not appear to present signifi cant risk to patients for developing spinal-epidural hematomas. There is no recommendation to discontinue aspirin or other NSAIDS prior to spinal injection in the ASRA guidelines. Normal clotting requires 40% or greater clotting factor activity. An INR value of 1.5 indicates approximately 40% activity of clotting factors and essentially normal ability to clot. This value has been derived from studies correlating hemostasis with clotting factor activity levels. INR below 1.5 is considered safe for spinal injection. Cyclooxygenase (COX) exists in 2 forms. COX-1 regulates constitutive mechanisms, while COX-2 mediates pain and infl ammation. NSAIDs inhibit platelet COX 1 and COX 2 and prevent the synthesis of thromboxane A2. NSAIDS inhibit platelet function. Celecoxib (Celebrex) and Rofecoxib (Vioxx) are anti-infl ammatory agents that primarily inhibit COX-2,an inducible enzyme which is not expressed in platelets. Therefore COX 2 inhibitors do not cause platelet dysfunction. Platelets from patients who have been taking COX 2 inhibitors have normal platelet adherence to subendothelium and normal primary hemostatic plug formation. After single and multidosing regimens, there have not been fi ndings of signifi cant disruption of platelet aggregation, nor is there a history of undesirable bleeding events. It has been suggested that the Ivy bleeding time is the most reliable predictor of abnormal bleeding in patients receiving antiplatelet drugs. However, there is no evidence to suggest that a bleeding time can predict hemostatic compromise and this test is not recommended to determine safety of spinal injection in the setting of platelet inhibition.

1116. A 70 year old woman with spinal stenosis and lumbar radiculopathy is hospitalized for TIA episodes. She is placed on intravenous low molecular weight heparin (LMWH) because she is at high risk for stroke. You are asked by the neurologist to perform a lumbar epidural injection prior to hospital discharge to treat her radiculopathy. The patient stops heparin and clotting returns to normal as measured by pre-procedure aPTT. You then perform an atraumatic L3-4 epidural steroid injection. She is re-heparinized 2 hours after injection. 24 hours later she begins complaining of increased back pain and increasing numbness and weakness in her lower extremities. You are concerned about spinal hematoma. The following statement(s) are true: 1. Epidural hematoma is unlikely because 24 hours have passed since injection. 2. Surgical decompression of spinal hematoma has good outcome if performed within 24 hours of onset of symptoms. 3. Severe back pain is the most common presenting complaint of patients with epidural hematoma. 4. The best test to order fi rst is an emergency MRI scan of the spine.
1116. Answer: D (4 Only) Explanation: Reference: Horlocker, et. Al. Regional Anesthesia in the Anticoagulated Patient: Defi ning the Risks (The Second ASRA Consensus Conference on Neuraxial Anesthesia and Anticoagulation) Spinal hematoma, defi ned as symptomatic bleeding within the spinal neuraxis, is a rare and potentially catastrophic complication of spinal or epidural anesthesia. The actual incidence of neurologic dysfunction resulting from hemorrhagic complications associated with central neural block is unknown. In an extensive review of the literature, Tryba identifi ed 13 cases of spinal hematoma following 850,000 epidural anesthetics and 7 cases among 650,000 spinal techniques. Based on these observations, the calculated incidence is approximated to be less than 1 in 150,000 epidurals and less than 1 in 220,000 spinal anesthetics. Hemorrhage into the spinal canal most commonly occurs in the epidural space, most likely because of the prominent epidural venous plexus. Between 1993 and 1998, there were 45 cases of spinal hematoma associated with LMWH, 40 of which involved a neuraxial anesthetic.Severe radicular back pain was not the presenting symptom; most patients complained of new onset numbness, weakness, or bowel and bladder dysfunction. Neurologic compromise presented as progression of sensory or motor block (68% of patients) or bowel/bladder dysfunction. Approximately half of patients reported neurological defi cits 12 hours or more following spinal procedure. Median time interval between initiation of LMWH therapy and neurologic dysfunction was 3 days, while median time to onset of symptoms and laminectomy was over 24 hours. Only 38% of patients had partial or good neurological recovery and spinal cord ischemia tended to be reversible in patients who underwent laminectomy within 8 hours of onset of neurological dysfunction. Early diagnosis by MRI scanning is therefore of paramount importance. Source: Schultz D, Board Review 2004

1122. Answer: A (1,2, & 3) Explanation: (Shah, et. al. Recurrence and spread of CRPS, accepted to American Journal of Orthopedics) Complex regional pain syndrome (CRPS) describes a constellation of sensory, motor, autonomic, and trophic disturbances, with spontaneous pain and hyperalgesia being the most persistent signs (Birklein). The term, ‘CRPS’, was introduced by a consensus group in 1996, to describe a variety of painful conditions that follow injury (Stanton-Hicks). They are characterized by spontaneous pain or hyperalgesia, a distal regional predominance, variable progression over time, impairment of motor function, and a magnitude and duration exceeding the expected clinical course of the inciting event; temperature, skin color, edematous, and sudomotor abnormality are or have been present (Stanton-Hicks 1998). The two subtypes include all the foregoing features but either exclude (CRPS I) or include (CRPS II) a peripheral nerve injury (Stanton-Hicks).

1128. Answer: C (2 & 4) Explanation: Short-term immobilization of the neck maybe appropriate to provide relief. However, prolonged immobilization leads to weakening of the cervical spine musculature. Nonsteroidal anti-infl ammatory medications provide analgesia and reduce infl ammation may be benefi cial in the shortterm. Benzodiazepines are not analgesics despite their purported effi cacy in reducing muscle spasm. Rather, biofeedback and psychological counseling may be more appropriate. Other less addicting and sedating ‘muscle relaxants’ maybe more appropriate, e.g., baclofen or tizanidine. Cervical medial branch neurotomy in those selected with placebo controlled diagnostic blocks may benefi t patients with whiplash. Source: Shah RV: 2003 (Bonica, 3rd Ed., page 1010)

1129. Which of the following percutaneous procedures compares favorably to re-operation in the management of failed back surgery syndrome? 1. Spinal cord stimulation 2. Peripheral nerve stimulation 3. Radiofrequency denervation of the lumbar facet joints 4. Translaminar epidural steroid injections
1129. Answer: B (1 & 3) Explanation: The term failed back surgery syndrome refers to persistent or recurrent chronic pain after one or more surgical procedures on the lumbosacral spine. Management is mired in controversy. However, radiofrequency denervation of the lumbar facets compares favorably to re-operation in long-term followup. Spinal cord stimulation also compares favorably to reoperation. Although SCS is best described for radicular pain, it may also be useful for axial pain. Peripheral nerve stimulators are usually reserved for patients with a well defi ned single peripheral nerve injury and complex regional pain syndrome. Placement must be proximal to the injured nerve. In radiculopathy, this would require placement in a retrograde approach parallel to the descending root, i.e., in the lateral recess and out towards the foramen. This technique, although described, is not widely practiced. Translaminar epidural steroids have been mired in controversy in patients without previous back operations. Only a few studies have demonstrated short term benefi t in failed back surgery syndrome and they too, probably won’t escape the attack of the evidence-based axe.

CSF passes from the lateral to the 3rd ventricle via the foramen of Lushcka 3. CSF is formed by arachnoid villi 4. The total volume of CSF is 150 ml., of which 25-30 cc are in the spinal subarachnoid space
1131. Answer: D (4 only) Explanation: (Raj, Practical Management of Pain, 3rd Ed., page 632) Cerebrospinal fl uid (CSF) is a clear, colorless ultrafi ltrate of blood formed by the choroid plexuses in the ventricles of the brain. CSF passes through the interventricular foramen of Monro into the third ventricle, then through the cerebral aqueduct to the fourth ventricle. It exits the fourth ventricle by way of the lateral and median foramina of Luschka and Magendie to reach the subarachnoid space. CSF is then absorbed by arachnoid villi that project from the subarachnoid space. The total volume of CSF is about 150ml, with about 25 to 35ml contained within the spinal subarachnoid space.

1135. Factitious disorder is differentiated from malingering by which of the following characteristics? 1. The production of physical signs is under voluntary control 2. The presence of a serious organic disorder as a comorbid factor 3. The primary motivation of the patient is to assume the sick role. 4. The absence of secondary gain
1135. Answer: D Explanation: 1.In factitious disorder, the patient intentionally produces physical or psychological signs or symptoms that are under voluntary control and are not explained by any other underlying physical or mental disorder. 2.There is no serious organic disorder. 3.The primary motivation of the behavior is to assume the sick role. In factitious disorder however, there is no secondary gain such as economic benefi t or avoidance of legal responsibilities. In malingering, the patient has an obvious recognizable secondary gain in producing their signs and symptoms such as avoiding work or prosecution, or obtaining fi nancial gain. 4.Absence of secondary gain is the main feature that differentiates factitious disorder from malingering.

1140. Effects of spinal cord stimulation on circulation include: 1. Increase in capillary density within stimulated region 2. Increase in red cell volume within microcirculation at stimulation target 3. Increase in number of capillaries perfused within stimulated region 4. Decrease in diastolic blood pressure
1140. Answer: A ( 1, 2, & 3) Explanation: Spinal cord stimulation causes vasodilation in the stimulated region. This effect is the result of microvascular changes occurring at the capillary level most likely as a result of central inhibition of sympathetic neurons. Spinal cord stimulation does not cause macrocirculatory changes and blood pressure and pulse remain unchanged.

1146. A 70 year old woman with spinal stenosis and lumbar radiculopathy is hospitalized for TIA episodes. She is placed on intravenous low molecular weight heparin (LMWH) because she is at high risk for stroke. You are asked by the neurologist to perform a lumbar epidural injection prior to hospital discharge to treat her radiculopathy. Which of the following statements regarding heparin and spinal injection are true? 1. LMWH should be stopped for a minimum of 24 hours prior to spinal injection 2. Low dose, subcutaneous heparin (5000 units every 12 hours) creates minimal increased risk for spinal hematoma with spinal injection 3. There is a higher incidence of spinal hematoma associated with LMWH than with unfractionated (standard) heparin 4. An epidural catheter may be safely removed in a fully heparinized patient
1146. Answer: A ( 1, 2, & 3) Explanation: Reference: Horlocker, et. Al. Regional Anesthesia in the Anticoagulated Patient: Defi ning the Risks (The Second ASRA Consensus Conference on Neuraxial Anesthesia and Anticoagulation) When heparin is administered in the setting of spinal injection, there is increased risk for spinal bleeding in certain situations. The concurrent use of medications such as oral anticoagulants antiplatelet medications that affect other components of the clotting mechanism may increase the risk of bleeding complications for patients receiving standard heparin. Guidelines for spinal injection in the patient receiving standard, unfractionated heparin were established over 2 decades ago and are well outlined in the ASRA article listed above. Placement of a needle into the spinal canal and withdrawing a catheter from the spinal canal are both possible causes for epidural hematoma in the heparinized patient and recommendations for performing either spinal injection or catheter removal are similar. The following table illustrates the relative risk of spinal injection in various scenarios involving heparin: During SC heparin (mini-dose) prophylaxis, there is no contraindication to the use of neuraxial techniques. The risk of neuraxial bleeding may be reduced by delay of the heparin injection until after the block and may be increased in debilitated patients after prolonged therapy. Because heparin-induced thrombocytopenia may occur during heparin administration, patients receiving subcutaneous heparin for greater than 4 days should have a platelet count assessed prior to neuraxial block and prior to catheter removal. With unfractionated heparin, administration should be delayed for 1 hour after needle or catheter placement. In patients receiving heparin pre-procedure, spinal injection and/or catheter removal shouldbe performed after heparin cessation only after clotting status has returned to normal as determined by activated partial thromboplastin time (aPTT). Typically spinal injection should be delayed for at least 4 hours after the last heparin dose and indwelling neuraxial catheters should be removed 2 to 4 hours after the last heparin dose. Re-heparinization after spinal intervention should be delayed for 1 hour or longer. The biochemical and pharmacologic properties of LMWH differ from those of unfractionated heparin and patients receiving LMWH heparin are considered to be higher risk for spinal hematoma. During the fi rst 5 years of LMWH use in the United States, some 60 epidural hematomas were reported, prompting a “black box” warning label by the FDA.The most relevant differences with LMWH are its’ pro-longed half-life, its’ irreversibility with protamine and the lack of monitoring of the anticoagulant response with standard lab testing. Prolonged LMWH therapy may be associated with an accumulation of anti-Xa activity and fi brinolysis. Patients on preoperative lower dose LMWH for thromboprophylaxis can be assumed to have altered coagulation. In these patients, needle placement should occur at least 10 to 12 hours after the last LMWH dose. Patients receiving higher doses of LMWH for anticoagulation, such as enoxaparin 1 mg/kg every 12 hours, enoxaparin 1.5 mg/kg daily, dalteparin 120 U/kg every 12 hours, dalteparin 200 U/kg daily, or tinzaparin 175 U/kg daily will require delays of at least 24 hours to assure normal hemostasis at the time of needle insertion.

1147. A patient undergoes a left stellate ganglion block without fl uoroscopic guidance. One week later the patient develops intermittent fever and increasingly severe posterior neck pain. The following statements are true: 1. The patient should be treated with a 10 day course of oral antibiotics. 2. Discitis is more likely after a left-sided vs. a right sided stellate block. 3. Symptoms are most likely unrelated to the stellate ganglion block. 4. The most appropriate immediate work up includes ESR, C-reactive protein and cervical MRI scan.
1147. Answer: C (2 & 4) Explanation: Reference: Pyogenic cervical epidural abscess and discitis following stellate ganglion block Vadodaria B.S., Bridgens J. and Richmond M. Anaesthesia 2001 56:9 (871-873) Disc space infection (commonly called discitis) is a rare but potentially catastrophic complication of injection into the spinal region. Any time a needle enters an intervertebral disc there is a potential for this complication. Epidural abscess and/or vertebral body osteomyelitis are common consequences of untreated disc space infection. Symptoms may include increasingly severe neck pain worse with movement, fevers and general malaise. Rapid diagnosis and aggressive treatment are of vital importance to prevent severe neurological consequences and life-threatening infection. The most important early diagnostic maneuvers include laboratory analysis with ESR and C-reactive protein and emergent MRI scan. ESR is a somewhat nonspecifi c test and Creactive protein is more specifi c and sensitive for discitis. The MRI may be relatively normal early on in the course of discitis and repeat MRI scans may be used to reevaluate and track progression or regression of disc space infection. MRI is also important to rule out epidural abscess which may require surgical intervention. Irradication of disc space infection in the relatively avascular disc is diffi cult and treatment typically includes intravenous antibiotics for a period of many weeks. Discitis is most commonly associated with discography but can occur after stellate ganglion block since the needle is in close proximity to the disc and disc penetration can occur. In the cervical region, the esophagus is a left-sided structure and any needle traversing the esophagus and entering a cervical disc has the potential to cause disc space infection. For this reason, cervical discography is always performed from the right side. Left-sided stellate ganglion block therefore has an inherently higher risk of discitis.

1148. A 50-year old typist complains of numbness of 6 weeks in duration in her entire right hand that is relieved by placing her hand under cold running water. Numbness and tingling are prominent to the index fi nger when driving her car or typing. She had entered menopause fi ve years previously. She is also a non-insulin dependent diabetic for approximately 10 years. There was no evidence of diabetic neuropathy. The true statements regarding this patient’s condition include: 1. She suffers with carpal tunnel syndrome 2. Nerve conduction studies showed a prolong residual latency and normal conduction velocity in the forearm 3. Treatment includes non-steroidal anti-infl ammatory agents, a cock-up volar splint with wrist is loose-packed position (10° to 30° dorsifl exion) to be worn during day and night and tendon-gliding exercises. 4. Her diagnosis is C6 radiculopathy caused by cervical spondylosis.
1148. Answer: A (1,2, & 3) Explanation: Carpal tunnel syndrome is one of the most common, best defi ned, and most carefully studied entrapment neuropathies. It affects middle-aged females between 40 and 60 years of age, that is menopausal women, a characteristic suggestive of a hormonal aberration as a causative development of this disorder. The most common cause of carpal tunnel syndrome is an idiopathic non-specifi c fl exor tenosynovitis that may simply arise from chronic repetitive occupational stress, both in males and females. Carpal tunnel syndrome may occur acutely after lunate bone dislocation or from a Colles’ fracture and requires immediate medical attention as to prevent acute nerve ischemia. * Carpal tunnel syndrome may be subdivided into one of the four categories. - An increase in volume or tunnel content secondary to non-specifi c tenosynovitis of the fl exor tendons within the carpal tunnel - Thickening or fi brosis of the transverse carpal ligament - Alteration of the osseous modus of the carpus caused by fractures, dislocations or arthritic joint changes - Tumor or systemic disease * The median nerve has both sensory and motorbranches. During median nerve compression at the carpal tunnel sensory, abnormalities usually occur fi rst only to progress to motor involvement as the pathology evolves. * Clinical fi ndings are proportional to the degree of nerve damage, which in turn is related to the severity of compression and not to the duration of compression. * The differential diagnosis includes C6 radiculopathy with refl ex changes and EMG studies showing denervation out of the median nerve territory and sensory loss of the 6th cervical dermatome. * Other diagnosis include: - Pronator syndrome referring to compression of the median nerve by pronator muscle as it passes through the heads of that muscle and to a lesser extent,by fi brous bands near the origin of deep fl exor muscles known as the lacertus fi brosis and fl exor digitorum superfi cialis arcade, and even less commonly by the ligament of Struthers, an analomous structure found in about 1% of the population. Pronator syndrome may also be expressed with expressed with median nerve paresthesias mimicking those of CTS, it differs in several aspects. Night pain, symptoms brought on by wrist movement, intrinsic weakness of opponents and abduction movements, as well as positive Phalen and Tinel wrist signs are not common to this condition. - Other conditions include anterior interosseous syndrome. - Carpal tunnel is diagnosed with positive Phalen’s test or Tinel’s sign where the median nerve is easily depolarized when mechanically stimulated by direct tapping over the palmaris longus tendon over the fl exor retinaculum. However, positive fi ndings occur only in approximately 45% of all cases. Source: Saidoff DC, McDonough AL. Critical Pathways in Therapeutic Intervention. Extremities and Spine. St. Louis,Inc., 2002

1179. Which of the following reduce the rate of post-dural puncture headache, actually or theoretically? 1. using a Whitacre needle instead of a Quincke-Babcock 2. using a 25 gauge needle instead of a 24 gauge 3. advancing a Quincke-Babcock needle parallel to the dura instead of perpendicular 4. using a 6 inch needle instead of a 4 inch needle
1179. Answer: A (1,2, & 3) Explanation: (Raj, Practical Management of Pain, 3rd Ed., page 633) Needle length, as well as needle tip shape, may affect the length of time you have to wait before recognizing thatyou are subarachnoid, i.e., it takes longer for CSF to drip out of a longer, as compared to shorter needle.Spinal needles vary with regard to length, inside and outside diameters, as well as the shape of their tip. The latter affects the size and shape of the hole made in the dura as well as the speedwith which CSF appears in the hub after dural puncture. The incidence of postdural puncture headache appears to be directly related to the size of needle used and the orientation of the needle in performing spinal anesthesia. A spinal needle oriented parallel to the dura separates the fi bers rather than cutting them, as a perpendicularly oriented needle does, and produces a smaller defect in the dura. All spinal needles come with a removable stylet, which must be close-fi tting to prevent coring of the skin and the resultant obstruction of the needle and contamination of spinal space with epidermal tissue and skin bacteria. Several spinal needle types and sizes are commercially available, although only two different needle tip points are available. The tip points can have either a beveled cutting point or a noncutting, rounded pencil point. The commonly used spinal needle with a cutting point is the Quincke-Babcock, which has a short bevel with cutting edges and a rounded heel. The cutting-point spinal needles appear to be associated with a high incidence of postspinal headache even when smaller needles are used. Spinal needles with a noncutting, rounded, pencil tip seem to cause less trauma to the dura mater and appear to be associated with a lower incidence of postspinal headache when larger-caliber needles are used. The Greene, Sprotte, Whitacre, and Huber needles have a noncutting, rounded, pencil tip. The Sprotte and Whitacre needles have completely rounded non-cutting bevels with solid tips, and the opening on their side approximately 2 mm proximal to the tip. These are currently the most widely used needles for spinal anesthesia as a result of their association with a reduced incidence of postdural puncture headache. Note: the Greene, Sprotte, Whitacre, and Huber needles do not have to be advanced parallel to the dura, since they are ‘pencil point’ needles. Source: Shah RV, Board Review 2005

1181. Which of the following statements is true regarding peripheral nerve stimulation: 1. Positive response to TENS is a reliable predictor for positive response to peripheral nerve stimulation 2. Pain relieving effects are caused by local anesthetic-like blockade of neural conduction within the peripheral nerve. 3. Pain due to nerve root injury often responds well to PNS 4. The best indication is pain in the distribution of a single traumatized peripheral nerve
1181. Answer: D (4 Only) Explanation: Reference: Heavner, Interventional Pain Management, Second Edition; Chapter 57 Peripheral Nerve Stimulation: Current Concepts The pain relieving effects of PNS are similar to those of SCS and are thought to be mediated by stimulation of Abeta fi bers within the peripheral nerve with subsequent activation of local inhibitory circuits within the dorsal horn. Peripheral nerve stimulation is best used to treat pain caused by trauma to a single peripheral nerve although two peripheral nerves within the same region can successfully be treated with a single stimulation system (2 leads and 1 pulse generator or receiver). Pain due to nerve root injury or to spinal mechanisms usually does not respond to PNS. Patients who have a positive response to TENS may be somewhat more likely to respond to PNS although TENS response is not a reliable predictor of PNS effect and a negative response to TENS does not mean that PNS should not be tried.

Gamma knife stereotactic radiotherapy of the hypothalamus is administered percutaneously 3. The analgesic mechanism is thought to be due to interruption of limbic pathways 4. One of the best described indications is diffuse pain due to bone metastases from breast or prostate carcinoma
1183. Answer: D (4 Only) Explanation: (Raj, Pain Review 2nd Ed., page 309) Percutaneous stereotactic instillation of alcohol is the best described technique. Other percutaneous methods for hypophysectomy include the use of radiofrequency thermocoagulation, cryotherapy, or radioactive seeds. Gamma knife radiotherapy is a noninvasive method for creating hypophyseal lesions. The analgesic mechanism is unknown, but limbic system or psychological effects are unlikely to be the reasons for pain relief. Hypophysectomy is recommended in the treatment of metastatic prostate and breast cancer, irrespective of the hormonal responsiveness of the tumors. Source: Schultz D, Board Review 2004

1189. A patient presents with an acute onset of upper extremity pain with numbness in the little fi nger. Physical examination showed weakness with fi nger fl exors. Most likely, diagnosis in this patient is: 1. C5 nerve root involvement 2. C6 nerve root involvement 3. C7 nerve root involvement 4. C8 nerve root involvement
1189. Answer: D (4 Only) Explanation: Flexor digitorum superfi cialis is supplied by a median nerve, C8. Similarly, fl exor digitorum profundus are also supplied by medial and ulnar nerves, C8. Lumbricals are supplied by median and ulnar nerve, C8 and T1.The fl exor digitorum profundus, which fl exes the distal interphalangeal joint, and the lumbricals,which fl ex the metacarpal phalangeal joint, usually receive innervation from the ulnar nerve on the ulnar side of the hand and from the median nerve on the radial side. If there is any injury to the C8 nerve root, the entire fl exor digitorum profundus becomes weak, with secondary weakness in all fi nger fl exors. If, however, there is a peripheral injury to the ulnar nerve, weakness will exist only in the ring and little fi ngers. The fl exor digitorum superfi cialis, which fl exes the proximal interphalangeal joint, has only median nerve innervation, and is affected by root injury to C8 and peripheral nerve injuries to the median nerve. C8 supplies sensation to the ring and little fi ngers of the hand and the distal half of the forearm. The ulnar side of the little fi nger is the purest area for sensation of the ulnar nerve, which is predominantly C8, and is most effi cient location for testing. Source: Hoppenfeld S.

1190. Subdural blockade is typically characterized by: 1. immediate onset of sensory and motor block 2. motor paralysis and sensory preservation 3. upper motor neuron signs 4. occurrence following the injection of a small volume of local anesthetic
1190. Answer: D (4 only) Explanation: (Raj, Practical Mgmt of Pain, 3rd Edition, page 648) The subdural space is a potential space between dura and arachnoid mater. Injection of drugs into this space can cause extensive and erratic spread. The onset of a block after a subdural injection characteristically is slower (5 to 10 minutes) than after an intrathecal block (3 to 5 minutes) but signifi cantly faster than an epidural injection (10 to 20 minutes). Moreover, a profound patchy sensory block with mild motor block may develop. Diagnosis can often be made by subsequent injection of a radiopaque dye in case an epidural catheter was threaded into the subdural space. A small volume of dye (e.g., 5 ml) shows an extensive spread of a very thin fi lm of the dye that is confined within the subdural space. The incidence of subdural injections is between 0.3% and 1%. Motor paralysis and sensory preservation is typically due to anterior spinal artery syndrome, whereas motor preservation and sensory loss is associated with subdural blockade.

1191. Loss of resistance to air or saline describes a method to access the epidural space. What are the characteristics of the ligamentous structure that offers ‘resistance’? 1. A ligament that is weaker than the supraspinous ligament 2. A ligament that is composed of 20% elastin 3. A ligament that spans from the anterior surface of the caudad lamina to the posterior surface of the cephalad lamina 4. A ligament that is referred to as the yellow ligament
1191. Answer: D (4 only) Explanation: (Raj, Practical Management of Pain, 3rd Ed., page 638) The ligamentum fl avum, which consists of more than 80% elastin, is the toughest of the three ligaments. It usually is easy to identify by its increased resistance to advancement of the epidural needle and ability to inject air or saline solution. It spans from the anterior surface of the cephalad lamina of an adjacent pair of vertebrae to the posterior aspect of the lower lamina. The ligamenta fl ava arise embryonically from two separate laminae. They fuse to a variable degree in the midline. Sometimes the fusion is incomplete, which may unintentionally lead to a dural puncture. The right and left halves meet at an angle of less than 90 degrees. The lateral edges wrap anteriorly around the facet joints. Source: Shah RV, Board Review 2005

``` 1197. Cervical traction would be useful in which of the following conditions 1. Arnold-chiari malformation 2. cervical myelopathy 3. rheumatoid arthritis 4. cervical disc herniation ```
1197. Answer: D (4 only) Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed., page 540) TRACTION In the therapy of traction, the soft tissues of the body (cervical or lumbar spine) are stretched by a pulling (traction) force. This force can be applied either manually or mechanically. Factors that determine the amount of separation (and thus pain reduction) include the position of the spine, the angle of pull, and the amount of force applied.Traction, when applied properly, may prevent adhesion formation, subdue painful muscle spasm, relieve pain, maintain anatomic alignment, and prevent or correct a deformity. Contraindications to the use of these techniques include acute trauma, infl ammation, hypermobility, increasing pain, and any spinal condition in which movement is to be avoided.

1211. Answer: B (1 & 3) Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed., page 536-538) All of the above are forms of therapeutic exercise. Therapeutic exercise may be broken down into Range of Motion, Resistive, Endurance Activities, Desensitization, Breathing Exercises, Relaxation, Coordination Training, and Proprioceptive Neuromuscular Facilitation. The goals of therapeutic exercise include: Strengthening the muscles. Improving fl exibility of muscles and tendons. Increasing endurance. Reinstating the normal pattern of motion to the affected muscles and to the body in general. 1. Isometric Resistive Exercise Isometric exercise is a static form of motion performed by contraction against an immovable object. 2. Active Assisted Range-of-Motion Exercises Active assisted movement is movement through a ROM by means of a muscular contraction supplemented by an external force either manually or mechanically 3. Isokinetic Resistive Exercise Isokinetic exercise is a form of dynamic motion in which the velocity of muscle shortening or lengthening and thus the velocity of the body part is controlled by a rate-limiting device 4. Proprioceptive Neuromuscular Facilitation In general, proprioceptive neuromuscular facilitation (PNF) is used to promote or hasten the response of the neuromuscular mechanism of the proprioceptors.

1213. Transcutaneous electrical stimulation: 1. Is based on the gate control theory of pain 2. Mechanistically activates large diameter afferent fi bers, in order to suppress afferent small fi ber input into the spinal cord 3. High intensity, low frequency stimulation is thought to work via a naloxone reversible mechanism 4. Low frequency, high pulse duration cause strong muscle contractions
1213. Answer: E (All) Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed., pages 534-535) 1.The gate control theory explains the mechanisms of pain relief associated with TENS treatment for many conditions. 2. Simply stated, this theory proposed the existence of a gating mechanism in the dorsal horns of the spinal cord, where there is an interaction between the small-diameter, unmyelinated C fi bers, which mediate the transmission of pain, and the larger-diameter, myelinated A fi bers, which mediate sensation of light touch and pressure. 3. High-intensity, low-frequency stimulation (frequently referred to as “acupuncture-like TENS”) also appears to offer pain relief, the effects of which can be reversed with naloxone, an opiate antagonis 4. Central to the discussion of the rationale of TENS therapy are its various stimulation parameters. Lowfrequency and high-pulse [width] energy cause strong, rhythmic muscle contractions.

1224. What are the advantages of performing a stellate ganglion block at C7 compared to C6? 1. Easier to identify anatomic landmarks by palpation 2. Increased risk of recurrent laryngeal nerve palsy 3. Decreased risk of pneumothorax 4. Reduced volume of local anesthetic is needed
1224. Answer: D (4 Only) Explanation: (Raj, Pain Review 2nd Ed.) Since the stellate ganglion is located at C7-T1, a C7 approach requires less volume. The risk of recurrent laryngeal nerve palsy is less at C7. There is an increased risk of pneumothorax due to the dome of the lung. The landmarks at C6 are easier to identify by palpation. The C6 transverse process is easier to identify than C7; the C6 transverse process, specifi cally the tubercle, is known as Chassaignac’s tubercle. There is an increased risk of pneumothorax at C7 as is the case for a supraclavicular approach to the brachial plexus. Source: Shah RV, Board Review 2003

1225. Each of the following items describes pain in the abdominal viscera: 1. Pain is transmitted via the vagus nerve 2. The nerve fi bers are type C versus A-delta 3. Pain is in a dermatomal distribution 4. Pain is characterized by a dull aching or burning sensation
1225. Answer: C (2 & 4) Explanation: 1, 2. Virtually all pain arising in the thoracic or abdominal viscera is transmitted via the sympathetic nervous system in unmyelinated type C fi bers. 3. Visceral pain is caused by any stimulus that excites nociceptive nerve endings in diffuse areas. Distention of a hollow viscus causes a greater sensation of pain than does the highly localized damage produced by transecting the gut. 4. Visceral pain is dull, aching, burning, and non-specifi c.

``` 1233. Potential complications associated with an ophthalmic nerve block include: 1. Orbital Perforation 2. Bradycardia 3. Ptosis 4. Miosis ```
1233. Answer: A (1, 2, & 3 ) Explanation: (Raj, Pain Review 2nd Ed.,) The opthalmic nerve block or the retrobulbar block is indicated for intraocular surgery and rarely, refractory eye pain. The goal of the technique is to block the ophthalmic branch of V1, the oculomotor nerve, abducens nerve, and trochlear nerve. The ciliary ganglion (located in the intracone area) will also be blocked. If this latter parasympathetic output is blocked, then one will see papillary dilatation (mydriasis) and not contraction (miosis). Cardiac arrhythmias have been reported with this block including the oculo-bradycardic refl ex. Globe perforation is possible with needle entry. Lid ptosis occurs since the oculomotor nerve supplies the superior levator palpebra. Recall that the sympathetics supply the superior tarsal muscle (elevates the eyelid) and may be spared…nonetheless, the block of the oculomotor will cause ptosis Source: Shah RV, Board Review 2003

1234. Which of the following is true about performing a ‘carpal tunnel’ injection? 1. It is indicated for analgesia of the 5th digit 2. The target nerve lies medial to the palmaris longus tendon 3. The injection is superfi cial to the fl exor retinaculum 4. The target nerve lies medial the fl exor carpi radialis tendon
1234. Answer: D (4 Only) Explanation: (Raj, Pain Review 2nd Ed.) The median nerve is the target in carpal tunnel injections and is the compressed nerve in carpal tunnel syndrome. However, the nerve (with the hands in supinated anatomic position) is located LATERAL to the palmaris longus and MEDIAL to the fl exor carpi radialis. It is not indicated for analgesia of the 5th digit. The median nerve that traverses the carpal tunnel provides sensory innervation to the radial 3 ½ digits on the palmar side, but distally on the radial side. The palmar branch of the median nerve does not go through the carpal tunnel and innervates the radial palm. The roof of the carpal tunnel is formed by the fl exor retinaculum; hence the injection should be deep and not superfi cial to this structure. Source: Shah RV, Board Review 2003

1235. Answer: A (1, 2, & 3) Explanation: In clinical practice, thermography is useful only as a means to measure skin temperature over a wide body area. 1. Thermography can also document locations of myofascial trigger points. 2. It has also been used to evaluate the degree of sympathetic blockade after stellate ganglion, lumbar sympathetic, or epidural blocks. 3.

1243. Each of the following is associated with an increased incidence of headache after spinal anesthesia: 1. Young age 2. Female gender 3. Pregnancy 4. Large needle size
1243. Answer: E (All) Explanation: Other factors that affect the incidence of spinal headache include the number of dural punctures and the position of the needle bevel. The incidence of spinal headache increases as the number of dural punctures increases. The incidence of headache has been shown to be less when the dural fi bers are split longitudinally rather than when they are cut while the needle is held in a transverse direction. The timing of ambulation relative to dural puncture has not been shown to affect the incidence of postspinal headache.

1249. With seizures following lidocaine injection, hyperventilation with 100% O2 is recommonded. The rationale for this therapy is to 1. Decrease delivery of lidocaine to the brain 2. Prevent hypoxia 3. Hyperpolarize the nerve membranes 4. Convert of lidocaine to the protonated (ionized) form
1249. Answer: A (1, 2, & 3) Explanation: 1. Hyperventilation causes cerebral vasoconstriction and decreased delivery of local anesthetic to the brain. 2. Administration of 100% O2, during a seizure helps to prevent hypoxia in a patient who otherwise might not be breathing. 3. Hyperventilation includes hypokalemia and respiratory alkalosis, both of which result in hyperpolarization of nerve membranes and elevation of the seizure threshold. 4. Hyperventilation also raises the patient’s pH (respiratory alkalosis) and converts lidocaine into the nonionized (nonprotonated) from, which crosses the membrane easily. This has no beneficial effect.

Use of large-bore needles and glucose-containing local anesthetics also can raise the risk of spinal headache. Spinal headaches result from leakage of CSF through the dural sheath. The headache is typically frontal or occipital in location and is worsened by sitting or standing up. 4. There is some evidence that the incidence of spinal headache is less after a dural puncture made through the paramedian approach. Source: Hall and Chantigan

``` 1256. A patient on tramadol (Ultram) and sertraline (Zoloft) develops confusion. Your diagnosis is: 1. Drug abuse 2. Drug withdrawal 3. Cardiac side effects 4. Serotonin syndrome ```
1256. Answer: D (4 Only) Explanation: Serotonin syndrome is a toxic hyperserotonergic state that develops soon after initiation or dosage increments of the offending agent. Patients may differ in their susceptibility to the development of serotonin syndrome. The (+) enantiomer of tramadol inhibits serotonin uptake. Tramadol is metabolized to an active metabolite, M1, by the CYP2D6 enzyme. If this metabolite has less serotonergic activity than tramadol, inhibition of CYP2D6 by sertraline may cause increased levels of serotonin in the synaptic cleft.

She recalls a worsening of her gastrointestinal symptoms a few days before the joint symptoms developed. Radiographs of the knee and ankle demonstrate soft tissue swelling and small effusions but no bone destruction. The true statements include: 1. The patient is HLA- B27 positive 2. The patient is experiencing the most common extraintestinal manifestation of infl ammatory bowel disease 3. Controlling the intestinal symptoms will eliminate the knee and ankle arthritis 4. The patient will go on to develop bone erosion and destruction of the knee and ankle
1259. Answer: B (1 & 3) Explanation: (Tierney, 42/e, pp 825-829) · HLA-B27 diseases are easy to remember with the mnemonic PAIR (Psoriasis, Ankylosing spondylitis, Infl ammatory bowel disease, and Reiter syndrome). These are called the seronegative spodylarthropathies. Reiter syndrome preceded by a bacterial infection (Yersinia, Salmonella, or gonococcus) has a high association with a positive HLA-B27. Ankylosing spondylitis has a 90% association with HLA-B27; overall, Reiter syndrome and infl ammatory bowel disease (IBD) have an 80% HLA-B27 association. Patients with IBD (Crohn’s disease and ulcerative colitis) may dev op a nonerosive oligoarthritis of the large peripheral joints that is usually eliminated after controlling the gastrointestinal symptoms. Arthritis is the second most common extraintestinal manifestation in patients the IBD (anemia is the most common extraintestinal manifestation). NSAIDs must be used with caution in patients with IBD.

1260. Answer: C (2 & 4) Explanation: Blockade of the accessory nerve (CN XI) is useful for trapezius muscle block as an adjunct to interscalene nerve blocks of the brachial plexus for surgery on the shoulder. The accessory nerve traverses the posterior triangle of the neck in a very superfi cial location. It emerges from the body of the sternocleidomastoid muscle at the junction of the superior and middle third of the posterior border of the muscle and therefore is frequently unintentionally blocked when a superfi cial cervical plexus block is performed.

1263. Post lumbar puncture headaches 1. Usually occur immediately following dural puncture 2. Are relieved 8 to 12 hours after an epidural blood patch is performed 3. Occur more frequently in nonpregnant compared with pregnant patients 4. Can be associated with neurologic defi cits
1263. Answer: D (4 Only) Explanation: Postspinal headaches are characterized by frontal or occipital pain, which worsens with sitting and improves with reclining. The etiology of postspinal headaches is unclear; however, they are believed to be caused by a reduction in CSF pressure and resulting tension on meningeal vessels and nerves (which result from leakage of CSF through the needle hole in the dura mater). 1. Usually occurs 24-48 hrs after lumbar puncture. 2. Conservative therapy for a postspinal headache include bed rest, analgesics, and oral and intravenous hydration. If conservative therapy is not successful after 24 to 48 hours, it is recommended that an epidural “blood patch” with 10 to 20 mL of the patient’s blood be performed. An epidural “blood patch” provides prompt relief of the postspinal headache. 3. Factors associated with an increased incidence of postspinal headaches include pregnancy, size and type of needle used to perform the block, age of the patient, the number of dural punctures. 4. Postspinal headaches may be associated with neurologic symptoms such as diplopia, tinnitus, and reduced hearing acuity. Source: Hall and Chantigan

1277. The true statements concerning neurolytic nerve blocks include. 1. There is little difference in the effi cacy between alcohol and phenol 2. Destruction of peripheral nerves can be followed by a denervation hypersensitivity that is worse than the original pain 3. Neurolytic blocks should be reserved for patients with short life expectancies 4. Neurolytic blockade with phenol is permanent
1277. Answer: A (1, 2, & 3) Explanation: Alcohol and phenol are similar in their ability to cause nonselective damage to neural tissues. Neural tissue will regenerate; therefore, neurolytic blocks are never “permanent” and neurolysis can lead to a denervation hypersensitivity, which can be extremely painful.

``` 1278. A nerve is undergoing Wallerian degeneration, but has preservation of the epineurium. This nerve injury could be classified as: 1. Seddon’s axonotmesis 2. Sunderland class 1 3. Sunderland class 4 4. Sunderland class 5 ```
1278. Answer: B (1 & 3) Explanation: Wallerian degeneration occurs following axonal loss hence, Sunderland class 1 (conduction block) is false. Sunderlan class 5 implies complete nerve transection, which is false. Other truisms would be Sunderland class 2,3,4—the epineurium is intact in all of these. Seddon’s axonotmesis would be true, because Wallerian degeneration would occur and the epineurium, endoneurium, and perineurium are intact. Source: Shah RV, Board Review 2004

1283. A 36-year old white male presents to your clinic with complaints of neck and upper extremity pain. on examination, shoulder abduction was relatively weak compared to the normal side. There was also weakness of elbow fl exion. An MRI of the neck will likely confi rm the presence of a disc protrusion at _____ level and involvement of ______ nerve root. 1. Disc protrusion at C4/5 2. Disc protrusion at C5/6 3. Neurological level C5 4. Neurological level C6
1283. Answer: B (1 & 3) Explanation: The deltoid and the biceps are the two most easily tested muscles with C5 innervation. The deltoid is almost a pure C5 muscle; the biceps is innervated by both C5 and C6, and evaluation of its C5 innervation may be slightly burred by this overlap. The deltoid is by axillary nerve or C5. It is a 3-part muscle. The anterior deltoid fl exors, the middle deltoid abducts, and the posterior deltoid extends the shoulder; of the three motions, the deltoid acts most powerfully on abduction. Since the deltoid does not work alone in any motion, it may be diffi cult to isolate it for evaluation. Therefore, note its relative strength in abduction, its strongest plane of motion. Primary shoulder abductors: 1. Deltoid (middle portion) C5, C6 axillary nerve 2. Supraspinatus C5, C6 suprascapular nerve Secondary shoulder abductors: 1. Deltoid (anterior and posterior portions) 2. Serratus (anterior) Biceps C5, C6, musculoskeletal nerve. The biceps is a fl exor of the shoulder and elbow and supinator of the forearm. To determine the neurologic integrity of C5, biceps should be tested only for elbow fl exion. Since the brachialis muscle, the other main fl exor of the elbow, is also innervated by C5, testing fl exion of the elbow should give a reasonable indication of C5 integrity. Source: Hoppenfeld S.

1287. Which of the following can be used to perform the sweating test, a special test of the function of the autonomic nervous system? 1. Cobalt blue papers 2. Iodine in oil and starch powder 3. Ferric chloride and tannic acid 4. Pilocarpine hydrochloride
1287. Answer: E (All) Explanation: Observation and physical examination of the patient provide substantial information about the function of the autonomic nervous system. Evaluation of endocrine status, body temperature, vital signs, skin and mucous membranes, perspiration, hair and nail growth, salivation, lacrimation, and extremities, as well as documentation of autonomic refl exes involving the cranial nerves should be performed prior to special tests of autonomic function. 1. Several tests exist to supplement the information obtained on examination of the patient. The sweating test will reveal areas of autonomic dysfunction. Cobalt blue papers will turn pink when exposed to moisture and will remain blue in areas of anhidrosis. 2. Iodine in oil will turn bluish black in the presence of starch and moisture. 3. Ferric chloride turns black in the presence of tannic acid and moisture. 4. Sweating can be elicited by application of external heat, ingestion of hot fl uids and aspirin, emotional stimuli, intellectual strain, painful cutaneous sensation, or subcutaneous injection of 5 mg of pilocarpine hydrochloride. Other tests of autonomic function include assessment of the pilomotor response, vasomotor response, refl ex erythema, histamine fl are, skin temperature, skin resistance, capillary microscopy, and plethysmography.

1290. An elderly man has had many years of deteriorating kidney function due to diabetes. Dialysis was begun because of electrolyte abnormalities, approximately ten years ago. True statements about his pain problems include: 1. The most common neurologic complication of chronic renal failure is Seizures and Delirium. 2. The most common neurologic complication of chronic renal failure is Peripheral neuropathy. 3. His symptoms of restless legs syndrome may be controlled with either Haloperidol or Nifedipine 4. The most reliable treatment for the peripheral neuropathy of chronic renal failure is Renal transplant.
1290. Answer: C (2 & 4) Explanation: 1, 2. The type of peripheral neuropathy most commonly developing with chronic renal failure is a symmetric, distal mixed sensorimotor neuropathy. The legs are generally affected fi rst and most severely. Men are more commonly affected than women. Most of the peripheral neuropathies in patients with chronic renal failure involve axonal degeneration. 3. The restless legs syndrome (Ekbom syndrome) is characterized by a feeling of discomfort in the legs that is relieved by movement.The sensation is felt deep within the limb, and is variably describes as pulling, stretching, or cramping. Restless legs syndrome occurs primarily at night, shortly after the patient lies down. It differs from akathisia, which is a restlessness that occurs during the daytime. It may be associated with peripheral neuropathy and anemia and is seen in patients with chronic renal disease, diabetes mellitus, and many other medical conditions. Exercise before going to bed may alleviate much of the discomfort. Agents that may be effective in alleviating symptoms include Clonazepam, gabapentin, Ldopa, and opiates. Neuroleptics, calcium channel blockers, and caffeine may worsen symptoms. 4. The neuropathy usually improves with dialysis or transplant. B vitamins are generally replaced when patients receive dialysis. Thiamine is water-soluble and so is easily lost during dialysis, but even replacing thiamine is not nearly as effective in retarding or reversing the neuropathy of chronic renal failure as is renal transplantation. There are presumed to be neurotoxins in the blood of patients with uremia that are not removed by routine dialysis Source: Anschel 2004

1292. Indications for prophylactic treatment in migraine are: 1. Upcoming job interview 2. Five migraine attacks a month 3. Tension type headache 4. Headaches associated with nausea
1292. Answer: C (2 & 4) Explanation: When deciding on the treatment of migraine, one must take into consideration the frequency and severity of the headaches. Prophylactic therapy is recommended if the headaches are more than 3 in a month, or are incapacitating requiring the patient to be hospitalized or miss work or the response to abortive medications is not satisfactory. A fi ne balance must be maintained between overmedicating and limiting acute attacks. It is not worthwhile to take prophylactic medication to prevent an occasional migraine once in two months. The aim of prophylactic therapy is to reduce the frequency and severity of the headaches by at least 50%. The best therapy for acute attacks is to use an abortive as in an upcoming job interview. Prophylactic therapy is not effective in tension type headaches. Migraines with prolonged aura can lead to permanent neurologic sequelae, in such cases prophylactic therapy maybe indicated.

1294. The true statements regarding the N-methyl-D-aspartate (NMDA) receptor include the following 1. Glutamate and aspartate act at the NMDA receptor 2. NMDA may be involved in injury-induced wind-up 3. Wind-up is prevented by NMDA antagonists 4. Ketamine is an NMDA receptor agonist
1294. Answer: A (1, 2, & 3 ) Explanation: NMDA receptors are involved in the activation of nociceptive neurons. The action of excitatory amino acids such as glutamateand aspartate at the NMDA receptor in the dorsal horn is enhanced by the neuropeptides substance P, calcitonin gene-related peptide (CGRP), and dynorphins. The corelease of excitatory amino acids and neuropeptides strengthens the synaptic connections in the dorsal horn andmay increase the development of dorsal-horn hyperxcitability (cord wind-up). There is an expansion of the receptive fi elds of the wide dynamic range (WDR) neurons. Wind-up is prevented by NMDA receptor antagonists. Both Mk-801 and ketamine are NMDA receptor antagonists.

1297.A young female presents with a severe left-sided throbbing headache associated with nausea, vomiting, and photophobia. She has tried taking ibuprofen without relief. On further questioning, she relates that she has been having similar headaches three to four months: 1. Appropriate therapy for this patient’s present headache includes Ergotamine tartrate. 2. Appropriate therapy for the present headache includes Amitriptyline hydrochloride 3. Appropriate long-term management includes a prescription for daily use of Amitriptyline hydrochloride. 4. Appropriate long-term management includes prescription for daily use of Sumatriptan and metoclopramide.
1297. Answer: B (1 & 3) Explanation: 1. This patient has migraine without aura. Of the agents listed, only Ergotamine tartrate is generally considered of use to abort a headache. 2. Verapamil and amitriptyline hydrochloride may be used as prophylactic (preventive) therapy. 3. Several medications are effective as prophylactic agents in the treatment of migraine. These include amitriptyline hydrochloride, propranalol, verapamil, and valproate. Most experts recommend initiating prophylactic therapy only when headaches occur at least one to two times per month. 4. Metoclopramide hydrochloride, sumatriptan, and Ergotamine tartrate are appropriately used to treat an acute attack of migraine, and should not be prescribed on a daily basis. Daily use of these medications can establish a rebound syndrome that results in a daily headache. Oral contraceptives may be associated with either an increase or decrease in the frequency of migraines, but are not generally used as a treatment for migraine. Some experts recommend not prescribing OCPs for patients with migraine for fear of increasing the risk of a stroke, although OCPs are probably safe to use in most patients with common migraine.

1299. The benefi cial effects of epidural administration of steroids have been attributed to of the following: 1. Inhibit phospholipase A2 2. Improve microcirculation around the nerve root 3. Block conduction of nociceptive C nerve fi bers 4. NMDA antagonist
1299. Answer: A (1, 2, & 3) Explanation: Administration of epidural steroids by interlaminar or transforaminal approach is one of the commonest approaches to treating spinal pain and radicular pain. Steroids decrease infl ammation by inhibiting phospholipase A2, thus inhibiting the formation of arachidonic acid, prostaglandins and leukotrienes. Steroids reduce infl ammatory edema around the infl amed nerve root and improve microcirculation. They block the conduction of nociceptive c fi bers. By restricting the formation of prostaglandins they may decrease sensitization of the dorsal-horn neurons. Source: Chopra P, 2004

1302. Answer: C (2 & 4) Explanation: Lateral epicondylitis, or tennis elbow, commonly involves the origin of extensor-supinator muscle mass in the: Extensor carpi radialis brevis Extensor digitorum communis Extensor carpi radialis longus Extensor carpi ulnaris Supinator The extensor carpi radialis is most commonly involved. Probably the position of wrist fl exion, elbow extension, and forearm pronation stretch the tendon over the prominence of the radial head.The most common cause of lateral epicondylitis is cumulative trauma. Provocative testing involves elbow in extension. Further, in lateral tennis elbow, pain is reproduced when one asks the patient to make a fi st and extend the wrist. Sudden, severe pain is elicited at the lateral epicondyle when the examiner forcefully extends the patient’s wrist. Source: Saidoff DC, McDonough AL. Critical Pathways in Therapeutic Intervention.

1313. Answer: C (2 & 4) Explanation: Waddell’s signs were developed to suggest a possible non-organic etiology of back pain as opposed to suggesting malingering. These tests and the clinician’s clinical impression may suggest a slower than expected recovery. The Waddell’s signs include (SONDSup, mnemonic): Simulation Load the spine with the weight of your hand on top of the patients head to reproduce low back pain Simulation of twisting the trunk when rotating the shoulders and hips in unison to reproduce the back pain Non-anatomic distribution of pain Aberrant pain drawing give away’ weakness, i.e., inconsistent effort during ange of motion Distraction Sitting knee extension to test sciatic tension while distracting the patient with a knee, foot, or peripheral pedal pulse examination If negative, then the supine straight leg maneuver should be negative Superfi cial or subcutaneous tenderness, not deep muscle tenderness 1. Evoked back pain with deep palpation of the lumber paraspinals is not a Waddell’s sign 2.

``` 1321. Which of the following tests are used to evaluate the meniscal injuries? 1. McMurray’s Test 2. Patellar Grind Test 3. Apley’s Compression Test 4. Lachman’s Maneuver ```
1321. Answer: B (1 & 3) Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed.) Special Tests 1. McMurray Test This maneuver was developed to assess for posterior meniscal tears and provides an excellent clinical evaluation. The patient lies prone. The examiner fl exes the symptomatic knee and rotates the tibia on the femur in external and internal rotation. Valgus stress is added with the leg in external rotation, and the knee is then slowly extended. An audible or palpable click suggests a meniscal tear. 2. Patellar Femoral Grinding Test Chondromalacia patellae is a common problem in degenerative knees, and there are common complaints of increasing pain on arising from a chair or climbing stairs. Exacerbation of symptoms can be elicited by compressing the patella into the femoral groove. With the knee extended, pressure is placed over the patella, which is guided along the groove. Crepitance should also be palpated with fl exion and extension of the knee while the examiner’s hand is over the patella. 3. Apley’s Compression or Grinding Test: A confi rmatory test for meniscal tears can be accomplished by compressing the meniscus. The patient lies prone and the affected knee is fl exed to 90 degrees. The examiner applies downward pressure against the heel as he or she rotates the tibia against the femur. Pain suggests a meniscal tear and correlates medially or laterally with the location of injury. 4. Drawer Signs These tests were designed to examine injury or disruption of the cruciate ligaments. The patient may be sitting or lying prone with the knee fl exed at 90 degrees and the foot fi xed in place (the examiner may sit on the foot). The tibia is then drawn toward the examiner; if the tibia slides beneath the femur, it is a positive anterior drawer sign and identifi es a torn anterior cruciate ligament (ACL). If sliding occurs beneath the femur when the tibia is pushed away from the examiner, it is a positive posterior drawer sign and identifi es a torn posterior cruciate ligament (PCL).

1330. Shoulder impingement should be suspected in a patient 1. that demonstrates a positive drop arm test 2. that demonstrates a ‘Popeye’ deformity 3. if the Yergason’s test is positive 4. has pain with abduction
1330. Answer: D (4 Only) Explanation: (Raj, Practical Mgmt of Pain 3rd Ed., page 347-9) 1. A drop arm test is consistent with a complete rotator cuff tear. A complete rotator cuff tear does not allow the arm to remain abducted, but partial tears can also be assessed by this test. The patient abducts the arm to 90 degrees and is asked to lower it slowly after the examiner taps the extended forearm. Complete tears in the supraspinatus tendon cause the arm to fall immediately to the side, and partial tears prevent full strength or range. 2. A ‘popeye’ deformity signifi es a tear of the long head of the biceps tendon Impingement is most pronounced with forward fl exion and thumbs down or abduction.Mechanical entrapmentof the rotator cuff occurs at the space between the humeral head and coracoacromial arch narrows. 3. The Yergason Test for Biceps Tendon Stability—while, the patient is sitting or standing, the examined elbow is fl exed at the waist and a fi st is made with the hand. The examiner has one hand on the patient’s elbow and the other on the distal forearm. The patient resists shoulder external rotation (examiner pulls outward on distal forearm) and pulls downward at the elbow. If the long biceps tendon pops out of its groove, pain arises near the anterior lateral humeral head. 4. Shoulder impingement produces pain with abduction. Source: Shah RV, Board Review 2004

1331. Positive Waddell’s signs are indicative of: 1. The effects of psychosocial factors 2. A poor response to surgical intervention 3. Need for a comprehensive evaluation of pain 4. Lack of response to treatment
1331. Answer: A (1, 2, & 3) Explanation: The 4 fi ndings include superfi cial, nonanatomic tenderness; a positive simulation response; a discrepancy between results of examination of the same body part in two different positions; and non-physiologic regional disturbances of sensation, pain or weakness. 1. Positive Waddell’s signs greatly increase the likelihood that psychosocial factors are playing a major role in the patient’s complaints. 2. Patients with two or more positive test results may not respond favorably to surgery. 3. Positive Waddell’s signs are indicative of the need for a comprehensive evaluation. 4. Patients with positive Waddell’s signs may not respond well.

1332. Which is true? 1. Axial loading of the neck may be helpful in the evaluation of chronic low back pain 2. The Adson test is used to evaluate thoracic outlet syndrome 3. Resistance to passive neck fl exion with the hands behind the head, so that the chin cannot touch the chest is a sign that is used to evaluate meningeal irritation 4. Increased neck pain with side bending is pathognomic for cervical facet pain
1332. Answer: A (1,2, & 3) Explanation: (Raj, Practical Mgmt of Pain, 3rd Ed., page 357, 358) 1. Axial loading of the neck is used in evaluating Waddell’s signs (simulation testing). Waddell’s tests were developed to evaluate functional overlay in low back paincomplaints. Each of the following fi ndings is considered positive if present; a total of three positive fi ndings is considered signifi cant, strongly suggesting positive non-physiologic signs. 2. The Adson test is used for subclavian artery compression. The patient’s radial pulse is continually taken at the wrist while the arm is abducted, extended, and externally rotated.The patient then takes a deep breath and turns the chin toward the tested arm. The examiner palpates a drop in pulse pressure or loss of pulse, suggesting compression of the artery. 3. Kernig test. The patient lies supine with hands behind the head and is asked to fl ex the chin to the chest wall. Nerve root, meningeal, or dural infl ammation results in a shooting pain in the spinal canal or legs. Tenderness: poorly localized and does not follow dermatomal or documented referral patterns. Light touch over the low back causing widespread discomfort or deep touch spreading through the thoracic spine or to the sacrum or hips. Simulation testing: should not be uncomfortable or cause discomfort in distant sites. Axial loading of the skull causing lumbar pain or shoulder rotation causing lumbar pain. Distraction testing: inconsistent fi ndings with the same test performed in formal fashion and when attention is distracted. Sitting straight leg raising without discomfort compared with lying straight leg raising causing radiating pain from buttock to foot. Regional disturbance: nonanatomical findings on sensory and motor testing. Give-way motor testing (total release of motor activity without warning) or unexplained weakness. Glove and stocking dysesthesias rather than expected dermatomal pattern. Overreaction: inappropriate facial or verbal expressions, withdrawal of limbs from touch, or posture contortions. Flopping on the fl oor with twisting of the spine, limiting hypersensitivity to joint examination, and cries of pain or fear on superfi cial examination. 4. Cervical facet joint pain is diagnosed with a certain degree of certainty, utilizing controlled diagnostic blocks - but not by physical examination. Source: Shah RV, Board Review 2004

1333. Which of the following observations, after nerve injury, is correctly paired with the appropriate nerve? 1. Inability to fl ex the forearm --- radial nerve 2. Numbness in the index fi nger---median nerve 3. Inability to extend the forearm---musculocutaneous nerve 4. Numbness in the little fi nger---ulnar nerve
1333. Answer: C (2 & 4) Explanation: To check the setup of a brachial plexus block, one can perform the four P’s (push, pull, pinch, pinch). Have the patient push or extend the forearm (triceps muscle is innervated by the radial nerve), pull or fl ex the forearm (biceps muscle is innervated by the musculocutaneous nerve), pinch the index or second fi nger (median nerve), pinch the little fi nger (ulnar nerve).

1335. A patient presents with pain in the upper extremity following injury to the forearm. Examination showed weakness in the ring and little fi ngers with numbness in the little fi nger. The most likely diagnosis is: 1. C7/T1 disc herniation 2. T1/T2 disc herniation 3. Median nerve injury 4. Ulnar nerve injury
1335. Answer: D (4 Only) Explanation: A peripheral nerve injury to the ulnar nerve causes weakness only in the ring and little fi ngers. However, a central lesion or disc herniation will cause weakness in all fi ngers. The fl exor digitorum superfi cialis, which fl exes the proximal interphalangeal joint, has only median nerve innervation, and is affected by root injury to C8 and peripheral injuries to the median nerve, but not peripheral injury to ulnar nerve Source: Hoppenfeld S.

1340. Tadpole lesions 1. Refers to the nerve swelling proximal to the area of the entrapped nerve 2. Refers to delamination of myelin and resultant accumulation in the internodes 3. Refers to appearance of ovoids, as the distal segment of the axon breaks down following axonal injury 4. Are early harbingers of the process of demyelination and remyelination that occur with conduction block
1340. Answer: C (2 & 4) Explanation: Tadpole lesions occur as a consequence of myelin delamination and accumulation into the paranodal bulbous aspects of the internode. They are early signs of demyelination and remyelination, which occur as a consequence of chronic entrapment and ischemia. The myelin is of irregular thickness in the entire region of the entrapment: thinner near the area of entrapment and thicker away from the middle. These are polarized, such that it looks as if a tadpole is swimming away from the region of the entrapment. During Wallerian degeneration, the axons in the distal segment breakdown and begin to look like ovoids. Nerve swelling proximal to the entrapped nerve can be visibly seen during surgery and it represents fi brosis, increased connective tissue, and endoneurial swelling Source: Shah RV, Board Review 2004
