Q
453. A 40-year-old man develops depressed mood, anhedonia, initial and terminal insomnia, loss of appetite, signifi cant weight loss, and sexual dysfunction. The clinical features of the patient’s psychiatric illness suggest dysfunction of the
A. Frontal lobes
B. Pituitary
C. Hippocampus
D. Hypothalamus
E. Corpus Callosum
A
  1. Answer: D
    Explanation:
    D. Clinical studies of patients with major depressive
    disorders indicate that an intrinsic regulatory defect
    involving the hypothalamus underlies the disorder. It also
    involves the monoamine pathways.
    The hypothalamic modulation of neuroendocrine activity
    has been implicated, as have been the neurotransmitter
    systems of serotonin and norepinephrine, in major
    depression. The evidence suggests a major role for the
    heritability of such neurochemical disorders.
    A, B, C & E. The frontal lobes, the pituitary, the
    hippocampus, and the corpus callosum are related to the
    emotions, memory, and neural communications.
    However, they do not play a major role in the depressive
    disorders as does the hypothalamus.

Q
  1. A young man with ankylosing spondylitis complains of
    neck, occipital, and shoulder pain. He denies any history
    of recent trauma or febrile illness. The most likely cause
    of his pain is:
    A. Compression fracture of C2
    B. Cervical osteomyelitis
    C. Atlantoaxial subluxation
    D. Epidural hematoma
    E. Cervical disc herniation C4/5
A
  1. Answer: C
    Explanation:
    Patients with ankylosing spondylitis may have erosion of
    the odontoid or destruction of the transverse ligament,
    which may allow C1 subluxation on C2.
    Patients will complain of neck, occipital, and shoulder
    pain. The subluxation is usually mild in these patients.
    Plain radiographs and MRI should be obtained to confi rm
    the diagnosis.
    Treatment is symptomatic.

when herpes zoster involves the:
A. Gasserian ganglion
B. Sphenopalatine ganglion
C. Ciliary ganglion
D. Geniculate ganglion
E. Trigeminal nerve
A
  1. Answer: D

Q
  1. A female patient presents with gluteal and leg pain. The pain is exacerbated when the patient lies down on the
    affected side or with crossed legs. Physical examination
    revealed local trochanteric tenderness with iliotibial
    band tightness and tenderness. The most likely diagnosis
    is:
    A. Piriformis syndrome
    B. Trochanteric bursitis
    C. Lumbar radiculopathy
    D. Sacroiliitis.
    E. Osteoarthritis of hip
A
  1. Answer: B
    Explanation:
    Trochanteric bursitis or gluteal fasciitis may be seen in
    approximately 25% of the patients with back pain
    predominantly in women.
    Etiology is typically unknown. However, one may fi nd leg
    length difference, abnormal gait, muscle tightness,
    osteoarthritis of the hip or spine, and occasional trauma.
    Signs and symptoms:
    Gluteal and leg pain, 64%
    Pain lying on affected side or with crossed legs, 50%
    Local trochanteric tenderness, frequently with iliotibial
    band tightness and tenderness
    Differential diagnosis of trochanteric bursitis includes
    osteoarthritis of hip, lumbar radiculopathy, and septic
    bursitis.

Q
  1. A young female patient presents with buttock and leg
    pain. She also reported occasional low back pain and
    severe dyspareunia. Physical examination showed pain
    on resisted external rotation and abduction of hip. The
    likely diagnosis in this patient is:
    A. Severe osteoarthritis of hip
    B. Piriformis syndrome
    C. Lumbar disc herniation
    D. Trochanteric bursitis
    E. Sacroiliac joint arthritis
A
  1. Answer: B
    Explanation:
    B. The description above indicates piriformis syndrome:
    Piriformis muscle originates medially from the inner
    surface of the sacrum and exits the pelvis through the
    greater sciatic foramen and attaches to the greater
    trochanter of the femur.
    The innervation is from the fi rst and second sacral nerves
    (S1 and S2).
    Buttock and nerve pain or pseudosciatica resulting from
    compression or infl ammation of sciatic nerve as it courses
    under or through piriformis muscle in buttock is the
    mechanism.
    There is no particular group at risk.
    Minor trauma to piriformis may result in muscle
    contraction or infl ammation.
    Pseudosciatica or buttock and leg pain is the most
    common symptom.
    Low back pain is seen in 50% of the patients.
    Dyspareunia is seen in 23%.
    Piriformis muscle tenderness may be found transrectally
    or transgluteally.
    There is pain on resisted external rotation and abduction of hip.
    There is also pain on internal rotation of hip.
    The piriformis should be assessed above and below 90° of
    hip fl exion.
    Reproduction of symptoms in combination with forceful
    internal rotation of the fl exed thigh is referred to as
    Freiberg’s sign.
    If you add adduction, it is called Bonnet’s sign.
    The pace maneuver also assesses weakness and pain with
    resisted abduction and external rotation of the thigh. This
    is done with the patient in the seated position.
    Tenderness may present throughout the length of the
    piriformis
    Differential diagnosis includes lumbar radiculopathy and
    sacroiliitis.

Q
464. The usual site of herniation of a cervical intervertebral
disk is:
A. Posterior
B. Lateral
C. Postero lateral
D. Anterior
E. Antero lateral
A
  1. Answer: C
    Explanation:
    The uncinate processes are bony protrusions located
    laterally from the C3 to C7 vertebrae. They prevent the
    disc form herniating laterally. The posterior longitudinal
    ligament is the thickest in the cervical region. It is 4 to 5
    time thicker than in the thoracic or lumbar region. The
    nucleus pulposus in the cervical disc is present at birth but
    by the age of 40 years it practically disappears. The adult
    disc is desiccated and ligamentous. It is mainly composed
    of fi brocartilage and hyaline cartilage. After the age of 40, a
    herniated cervical disc is never seen because there is no
    nucleus pulposus. The most common cervical herniated
    nucleus pulposus (HNP) occurs between the C6 to C7
    (50%) and followed by the C5 to C6 (30%)

Q
  1. Which of the following statements is true?
    A. Pneumothorax is a common complication of thoracic
    epidural.
    B. Thoracic facet pathology can refer pain to the scapular
    region
    C. The intercostal nerve innervates only the scapular
    region
    D. Noncardiac chest pain is purely psychogenic
    E. There is no risk of pneumothorax with a simple trigger
    point injection
A
  1. Answer: B
    Explanation:
    Pneumothorax is a risk from rib blocks and trigger point
    injections. The thoracic facets refer to the scapular region,
    but the intercostal nerve can refer into the anterior chest.
    There are multiple causes of noncardiac chest pain.

470. A 65-year old man with a history of chronic back pain has been a patient for 5 years, receiving 3-4 months relief from epidural steroid injections before pain increases to the level where repeat injection is required. Following 6 weeks after epidural, he presents to the clinic with the complaint of a recent increase in his pain. The pain is constant and is exacerbated by movement. NSAIDS, bedrest, and narcotics failed to help. There was no history of fever. The L4 and L5 vertebrae were tender to palpation. There was also paraspinal muscle spasm. No motor or sensory defi cits were present. The most likely diagnosis entertained in this patient: A. Vertebral osteomyelitis B. Spinal stenosis C. Herniated disc D. Paget’s disease E. Epidural abscess
470. Answer: A Explanation: The symptoms described in the question are consistent with the diagnosis of vertebral osteomyelitis. Clinical features include persistent, localized pain with heat, swelling, tenderness, and erythema over the involved bone. Fever may be low-grade or absent. Diagnosis can be made by history, physical examination, radiographic studies of the spine, bone scan, blood cultures, erythrocyte sedimentation rate, complete blood count, needle aspiration of the intervertebral disc space, or biopsy of infected bone. Staphylococcus aureus is the most common causative organism, but gram-negative bacteria can also cause osteomyelitis (most common in a urinary tract infection) (Bonica, pp 393-394).
26
471.Which of the following statements best described Conversion Disorder? A. Involves one or more symptoms or defi cits affecting voluntary motor or sensory function that suggest a neurological or other general medical condition. B. Psychological factors are not judged to be associated with the symptom or defi cit because the initiation or exacerbation of the symptom or defi cit follows confl icts with healthcare professionals. C. Patients intentionally produce or feign symptoms and defi cits to call attention to themselves. D. Symptoms or defi cit can after appropriate investigation be fully explained by a culturally sanctioned behavior or experience. E. It generally develops in late life.

473. A 41-year-old man presents with spastic legs, bilateral extensor plantar refl exes, hyperrefl exia and loss of sensation (position sense and vibration) of the lower extremities. Choose correct diagnosis: A. Upper motor neuron disease B. Lower motor neuron disease C. Myelopathy D. Radiculopathy E. Broca’s aphasia
473. Answer: C Explanation: A. Upper motor neuron (UMN) disease (above the level of the corticospinal synapses in the gray matter) is characterized by spastic paralysis, hyperrefl exia, and a positive Babinski refl ex (everything is up in UMN disease). B. Lower motor neuron (LMN) disease (below the level of synapse) is characterized by fl accid paralysis, signifi cant atrophy, fasciculations, hyporefl exia, and a fl exor (normal) Babinski refl ex (everything is down in LMN disease). C. Myelopathy causes severe sensory loss 0 posterior column sensation (position sense and vibration), spasticity, hyperrefl exia, and positive Babinski refl exes. D. A radiculopathy occurs with root compression from a protruded disk that causes sensory loss, weakness, and hyporefl exia in the distribution of the nerve root. E. Broca’s aphasia (left inferior frontal gyrus) is a nonfl uent expressive aphasia (Broca’s should remind you of broken speech); Wernicke’s aphasia (left posteriorsuperior temporal gyri) is a receptive aphasia because patients lack auditory comprehension (Wernicke’s should remind you of wordy speech that makes no sense).

``` 476. A patient with hallux valgus develops lateral displacement of the extensor and fl exor hallucis longus tendons. CHOOSE CORRECT DIAGNOSIS: A. Hammer toe B. March fracture C. Genu valgum D. Genu varum E. Bunion ```
476. Answer: E 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.

478. A 20-year-old college student develops left shoulder pain after jumping into a lake from a swinging rope. She presents holding her arm beside her body (adducted) and avoiding any shoulder movement. On examination, the rounded contour of the shoulder is lost and the head of the humerus is felt under the coracoid process. Which of the following is the most likely diagnosis? A. Inferior glenohumeral dislocation B. Rupture of the long head of the biceps C. Posterior glenohumeral dislocation D. Anterior glenohumeral dislocation E. Fracture of clavicle
478. Answer: D Explanation: (Seidel, 5/e, p 720.) Glenohumeral dislocations may be anterior, posterior, or inferior depending on the position of the head of the humerus in relation to the glenoid. The most common dislocation is anterior (>90%)and is due to forceful abduction, external rotation, or extension. There is typically fl attening of the deltoid and loss of the greater tuberosity, causing a squared-off appearance of the shoulder. The patient is usually in severe pain and holds the arm in slight abduction and external rotation. Posterior dislocations are typically seen following a seizure. Possible complications of shoulder dislocation include damage to the axillary artery, axillary nerve (deltoid paralysis), and brachial plexus. First-time dislocation requires orthopedic management (surgery or therapeutic exercise), since 80% of patients will have a recurrence. Rupture of the long head of the biceps causes a bulge in the lower half of the arm and pain on elbow flexion.

``` 479. A young, high school girl develops a painful vesicular rash around her left eye. This is followed by blurry vision that occurs only when both eyes are open. She is diagnosed with vericella zoster ophthalmicus. Which ocular motor nerve is most likely to be affected? A. Superior division of the third. B. Inferior division of the third. C. Fourth (trochlear) D. Sixth (abducens) E. Long ciliary ```
479. Answer: C Explanation: Varicella Zoster, or herpes zoster, spreads to the face along the trigeminal nerve. The fourth nerve is presumably involved because it shares its nerve sheath with the ophthalmic division of the trigeminal nerve. The third and sixth nerves may also be involved with varicella zoster, but this occurs much less frequently than involvement of the fourth nerve. Source: Anschel 2004

Atypical neuralgia C. Trigeminal Neuralgia D. Temporomandibular joint disorder E. Atypical facial pain
480. Answer: C Explanation: Trigeminal neuralgia (Tic Douloureux) is pain restricted to the distribution of the trigeminal nerve.It can be present in any of the three divisions - frontal (V1), maxillary or the mandibular. The commonest to be affected are the maxillary (V2) and the mandibular (V3). The peak incidence is mostly between the ages of 50 years and 70 years. The pain is intermittent with pain free intervals. It is described as a sharp, electric, stabbing, shooting pain. The triggers are chewing, swallowing, talking and exposure to cold. Trigeminal neuralgia is mostly unilateral. Atypical neuralgias are almost always constant with very rare pain free intervals. This is an important distinguishing symptom with trigeminal neuralgia. The pain burning in character and not sharp. It is not triggered by non-noxious stimulus. It tends to affect young adults. Source: Chopra P, 2004

481. A 43-year old male house painter reports shoulder pain of 2 weeks duration after a half a can of paint fell onto his right shoulder. He feels stiff and weak when attempting to elevate his right arm overhead. When attempting to elevate the shoulder, he does so with an overexaggerated right shoulder shrug up to 40° and suddenly fl ops down to his side. The most likely diagnosis is: A. Rotator cuff tear B. Cervical spondylosis C. Suprascapular neuropathy D. Brachial neuritis E. Bicipital tendonitis
481. Answer: A Explanation: Rotator cuff disorders encompasses four stages with Stage I with edema and hemorrhage, Stage II with tendonitis, Stage III with partial thickness tear, and Stage IV with full thickness tear of the rotator cuff. With partial thickness tear, there is history of tendonitis and patient can begin abduction but experiences pain or a painful arc during the attempt. Active abduction becomes more comfortable afterinjection of a local anesthetic and this feature helps differentiate tendonitis or a partial tear from a complete tear of the rotator cuff. Since the patient with a large tear does not regain strength after the subacromial space is anesthetized. Full thickness tear of the rotator cuff occurs, as the fi nal stage of the degenerative process in which the provoked tendon succumbs to something as trivial as opening up a stuck window or more seriously after sustaining a fall on the shoulder or on an outstretched abducted arm. A complete tear may also occur after greater humeral tuberosity fracture scar or from shoulder dislocations. Differential diagnosis includes bursitis, cervical spondylosis, suprascapular neuropathy, and brachial neuritis, etc. Source: Saidoff DC, McDonough AL. Critical Pathways in Therapeutic Intervention.

482. Following a radical mastectomy, the patient is found to have winging of the scapula when the fl exed arm is pressed against a fi xed object. This indicates injury to which of the following nerves? A. Axillary B. Long thoracic C. Lower subscapular D. Supraclavicular E. Thoracodorsal
482. Answer: B Explanation: A. The axillary nerve, deep in the brachial portion of the axilla, innervates the deltoid muscle. B. The serratus anterior muscle (protractor and stabilizer of the scapula) is innervated by the long thoracic nerve (of Bell), which arises from roots C5 to C7 of the brachial plexus. During modifi ed radical mastectomy, this nerve is usually spared to maintain shoulder function. However, its location places it in jeopardy during the lymphatic resection. C. The lower subscapular nerve innervates the teres major muscle and a portion of the subscapularis muscle. D. The supraclavicular nerves are sensory branches of the cervical plexus. E. The thoracodorsal nerve, which arises from the posterior cord of the brachial plexus, innervates the latissimus dorsi. Source: Klein RM and McKenzie JC 2002.

483. A middle-aged man presents with complaints of right elbow pain. He is an avid golf player. He does not play tennis. He tried high doses of Aspirin and Tylenol without any signifi cant relief. Physical examination showed resisted wrist extension with elbow extended and radial deviation, forced passive wrist fl exion and ulnar deviation, and forearm pronation with elbow extension reproduced the pain in the vicinity of lateral epicondyle. The appropriate diagnosis in this patient is: A. Radiohumeral joint infl ammation B. Radial tunnel syndrome C. Posterior interosseous nerve entrapment D. Lateral epicondylitis E. Medical epicondylitis
483. Answer: D Explanation: A. Radial humeral joint infl ammation and swelling may occur from rheumatoid arthritis, gout, or infectious arthritis, especially in the last if there has been a history of injections to this area, such as repeated steroid injections for recalcitrant tennis elbow. Swelling, if present, will occur between the lateral epicondyle and the olecranon process below. B. Radial tunnel syndrome may occur concomitantly with lateral epicondylitis and is a common cause of treatment resistant cases. It should be considered suspect when tennis elbow fails to respond to conservative treatment including injections. C. Involvement of the deep radial nerve is also known as posterior interosseous nerve entrapment. This may be confi rmed by a tension-test. The symptoms of entrapment of posterior interosseous nerve are similar to the radial tunnel syndrome in which pain is over the proximal dorsal forearm, with maximal tenderness at the site of radial tunnel, that is 4 cm distal to the lateral epicondyle over the posterior interosseous nerve. D. Lateral epicondylitis, or tennis elbow, is the most common affl iction. E. Medical epicondylitis or pain elicited on resisted wrist fl exion and pronation, as well as extremes of the passive wrist extension with the forearm supination and elbow extension and ulnar deviation eliciting the pain at the medial epicondyle.

484. An elderly woman presents with recent onset of swelling of the right arm, neck and face. Her right jugular vein is visibly engorged and her right brachial pulse is diminished. On the basis of these signs, her chest x-rays might show A. A left cervical rib B. A mass in the upper lobe of the right lung C. Aneurysm of the aortic arch D. Right pneumothorax E. Thoracic duct blockage in the posterior mediastinum
484. Answer: B Explanation: (April, 3/e, p 265.) A Pancoast tumor in the apex of the right lung may compress the right brachiocephalic vein with resultant venous engorgement of the right arm and right side of the face and neck. In addition, there may be compression of the brachial artery, the sympathetic chain, and recurrent laryngeal nerve with attendant defi cits. An aneurysm of the aortic arch could reduce pulse pressures as the great vessels are occluded, but it could not explain the venous congestion. Source: Klein RM and McKenzie JC 2002.

485. A woman presents with complaints of left shoulder and arm pain approximately 2 years after undergoing radiation therapy for breast cancer. Physical examination reveals lymphedema of the left axilla and pressure over the left supraclavicular area precipitating a sharp pain that radiates down her left arm. The likely diagnoses is: A. Thromboangiitis obliterans B. Refl ex sympathetic dystrophy C. Tumor metastasis D. Radiation-induced plexopathy E. Cervical radiculopathy
485. Answer: D Explanation: Radiation-induced fi brosis of the connective tissue surrounding the brachial plexus can cause compression and ischemic neuropathy. Symptoms have developed 6 months to 20 years after radiation therapy. The patient complains of deafferentation-type pain. It is characterized as progressively increasing, diffuse, and burning. Other symptoms and signs may include numbness, paresthesias, dysesthesias, and C5/6 motor weakness. There are signifi cant differences in symptoms in patients with metastatic plexopathy versus radiation plexopathy. Most patients with metastatic plexopathy develop sensory changes in C8/T1 distribution versus C5/6 in radiation plexopathy. Patients with metastatic plexopathy also have a much higher incidence of Horner’s syndrome, lymphedema, and swelling of the painful limb, and development of epidural deposits. Source: Bonica

486. A 20-year-old woman presents complaining of proximal forearm pain exacerbated by extension of the wrist against resistance with the elbow extended, She denies trauma but is an avid racquetball player. Which of the following is the most likely diagnosis? A. Lateral epicondylar tendinitis B. Medial epicondylar tendinitis C. Olecranon bursitis D. Biceps tendinitis E. Long thoracic nerve early paralysis
486. Answer: A Explanation: (Goldman, 21/e, pp 1559-1560.) Tennis elbow or lateral epicondylar tendinitis is most commonly characterized by tenderness of the common extensor muscles at their origin (the lateral epicondyle of the humerus). Passive fl exion of the fi ngers and wrist and having the patient extend the wrist against resistance causes pain. Golfer’s elbow or medial epicondylar tendinitis is a similar disorder of the common fl exor muscle group at its origin, the medial epicondyle of the humerus. Olecranon bursitis is an infl ammation of the bursa over the olecranon process caused by acute or chronic trauma (student’s elbow) or secondary to gout, rheumatoid arthritis, or infection. Clinically, there is swelling or pain on palpation of the posterior elbow. Paralysis of the serratus anterior muscle (innervated by the long thoracic nerve) causes the scapula to protrude posteriorly from the posterior thoracic wall when the patient is asked to push against a wall (winged scapula).

487. A 50-year old woman with systemic lupus erythematosus complains of fever, headache, and vomiting associated with a depressed level of consciousness over the last 24 h. She recently had begun taking ibuprofen as treatment for diffuse joint pain. CSF examination revealed neutrophilia and normal glucose. The most likely diagnosis is: A. Bacterial meningitis B. Drug-induced meningitis C. Fungal meningitis D. Viral meningitis E. Encephalitis
487. Answer: B Explanation: B. Drug-induced aseptic meningitis may be due to a hypersensitivity reaction to drugs such as ibuprofen, sulindac, tolmetin, trimethoprim-sulfamethoxazole, azathioprine, penicillin, isoniazid, phenazopyridine, and sulfonamides. Facial swelling, urticaria, pruritus, and conjunctivitis may also occur along with the fever, headache, vomiting, and depressed level of consciousness. Symptoms usually resolve rapidly after the causative drug is eliminated. CSF studies show predominance of neutrophils and low or normal glucose. Patients with lupus, Sjögren’s syndrome, or mixed connective tissue disease have the greatest risk of developing drug-induced meningitis. The incidence is higher in women. Source: Kahn CH, DeSio JM.

Organic and functional C. Genetic and familial D. Neuropathologic and sociopathologic E. Psychoanalytic and dynamic ```
488. Answer: B Explanation: The relationship between social and biologic processes has historically been regarded by psychiatry and medicine as organic and functional. Organic mental illnesses have included the dementias and the toxic psychoses. The functional mental illnesses have included the various depressive syndromes, the schizophrenias, and the neuroses. The Psychoanalytic (dynamic) approaches and an understanding of conditioning (learning) played important roles in the evolution and development of an integrated biobehavioral understanding of human behavior and human biology.

493. A 40-year-old male presents with anterior shoulder pain. Physical examination shows full range of motion with painful arc present on elevation and depression at approximately 50° on both the upswing and the downswing. There is no muscle wasting. There is no cuff wasting and the patient admits to a history of cuff impingement and suspected tear of his right shoulder of several years’ duration that was operated a year before. There is tenderness noted in the shoulder, shoulder abduction, and glenohumeral rotation are painful. The likely diagnosis is: A. Bicipital tendonitis B. Anterior shoulder instability C. The coracoid impingement syndrome D. Subdeltoid bursitis E. Glenohumeral joint arthritis
493. Answer: A Explanation: The biceps, a long fusiform muscle that arises by two heads, has no direct connection with the humerus as it originates above the shoulder and inserts below the elbow joint. The long head of the biceps arises from the supraglenoid tubercle and arches obliquely over the top of the humeral head within the capsule of the shoulder joint. The biceps tendon is intraarticular but extrasynovial. The short head of the biceps arises within the coracobrachialis from the scapulas coracoid process and runs down the medial side of the long head of the biceps. The two belles join as a common distal tendon shortly the elbow joint as fl attened tendon, only to separate into two distal insertions. The most common cause (95% to 98%) of bicipital tendonitis actually results as a secondary involvement of the biceps after primary impingement or tearing of the rotator cuff. Proximal biceps tendonitis is evidenced by proximal anterior shoulder pain and possibly a painful arc during shoulder fl exion and extension while the biceps is tensed and by tenderness in the bicipital groove on palpation. Pain may radiate to the muscle belly or proximally, like pain from cuff impingement, radiate to the deltoid insertion. However, there is no radiation into the neck or distally beyond the biceps muscle belly. Pain is less intense during rest and worse with use. Nighttime exacerbation is common.

501. A 47-year-old man fell on his outstretched right hand while rollerblading. Several days later, he develops right wrist pain that is constant and progressive. Pain is in the area of the anatomical snuffbox and is worse with wrist flexion, extension, and ulnar deviation. The anatomical snuffbox is tender to palpation but there is no swelling. Finkelstein test is negative. Which of the following is the most likely diagnosis? A. Cervical radiculopathy B. Scaphoid fracture C. Compartment syndrome D. de Quervain’s disease E. Boxer’s fracture
501. Answer: B Explanation: A. Cervical (C6-C8) radiculopathy causes pain, numbness, and tingling from the neck to the hand. B. Scaphoid fractures occur as a result of a fall on an outstretched hand. These fractures heal poorly due to a poor blood supply in this area. Radiographs done early may be negative, but later radiographs may show evidence of healing (callus fracture). C. Compartment syndrome is a surgical emergency and is due to a tight cast or swelling causing compression of the blood vessels and nerves in the forearm. D. de Quervain’s disease or tenosynovitis of the tendon sheath of the extensor pollicis brevis and abductor pollicis longus causes swelling and tenderness of the anatomic snuffbox. This disorder is usually found in middle-aged women who perform repetitive activity. The Finkelstein test is positive (patient makes a fi st around his or her own thumb; pain is produced with adduction toward the ulnar side) in de Quervain’s disease. E. A boxer’s fracture causes fl attening or loss of the fi fth knuckle prominence due to displacement of the metacarpal toward the palm.

503. A 36-year-old executive of a Wall Street fi nancial company presents with headaches for many years. The headaches are episodic. Usually on the left side, they may occur in the maxillary, frontal or temporal region. Each attack lasts for approximately 2 hours. He describes the pain like a knife being driven through the head. It often wakes him up in the morning. The headache attacks some several times a day. This may continue for a week at a time. When he has an attack he is restless and unable to fi nd a comfortable position. What is the diagnosis? A. Tension type headache B. Hypertensive headache C. Subdural hematoma D. Cluster headaches E. Intractable Migraine with Aura
503. Answer: D Explanation: A. Tension type headaches are constricting B. Hypertensive headaches are associated with nausea, vomiting, seizures and confusion. - There is a sudden rate of increase of blood pressure. - The headache is sudden, severe and unrelenting. - Fundoscopic examination often reveals severe hypertensive vascular changes. C. Subdural hematomas are commonly secondary to a trauma or anticoagulation therapy. - There is tearing of the bridging veins. - The headaches are chronic, mild to moderate in severity. - Neurological changes are usually subtle. D. Cluster headaches are unilateral, temporal, frontal or temporal. Cluster headaches are 6 times more common in men. - The usually start between the 3rd and 4th decade of life. - These are short lasting attacks that come together over a period of time. - They may have several attacks in a day and this may continue for several weeks or months. The headaches are very severe and sharp, often associated with lacrimation and conjunctival injection. - In contrast to migraines, these patients tend to restless and pace up and down. Abortive management of an acute cluster headache includes: oxygen by face mask, ergotamine (nasal) or sumatriptan. - Preventive treatment is recommended because of the severity of the attacks. A short course of steroids, lithium verapamil and/or valproic acid can be used. E. Intractable migraine with aura is associated with one or more fully reversible symptoms. Source: Chopra P, 2004

507. A middle aged woman in late 50’s presents with a one year history of weakness and diffi culty with walking, with no signifi cant pain. Exam fi ndings include weak, wasted muscles with spasticity, fasciculations, extensor plantar responses, and hyperrefl exia. Most likely diagnosis is: A. Dorsal spinal root disease B. Ventral spinal root disease C. Arcuate fasciculus damage D. Motor neuron disease E. Purkinje cell damage
507. Answer: D Explanation: Motor neuron disease in the anterior horns of the spinal cord and damage to the corticospinal tracts or motor neurons contributing axons to the corticospinal tracts would account for these neurologic signs. Damage to the dorsal spinal root would be expected to produce sensory, rather than motor, defi cits and would produce arefl exia, rather than hyperrefl exia, at the level of the injury. Damage to the ventral spinal roots would produce weakness and wasting, but no spasticity or hyperrefl exia would develop. Purkinje cell damage would be expected to produce ataxia without substantial weakness. The accurate fasciculus connects elements of the cerebral cortex not involved in the regulation of strength or motor tone. Source: Anschel 2004

509. Answer: A Explanation: A. Upper motor neuron (UMN) disease (above the level of the corticospinal synapses in the gray matter) is characterized by spastic paralysis, hyperrefl exia, and a positive Babinski refl ex (everything is up in UMN disease). B. Lower motor neuron (LMN) disease (below the level of synapse) is characterized by fl accid paralysis, signifi cant atrophy, fasciculations, hyporefl exia, and a fl exor (normal) Babinski refl ex (everything is down in LMN disease). C. Myelopathy causes severe sensory loss 0 posterior column sensation (position sense and vibration), spasticity, hyperrefl exia, and positive Babinski refl exes. D. A radiculopathy occurs with root compression from a protruded disk that causes sensory loss, weakness, and hyporefl exia in the distribution of the nerve root. E. Broca’s aphasia (left inferior frontal gyrus) is a nonfl uent expressive aphasia (Broca’s should remind you of broken speech); Wernicke’s aphasia (left posteriorsuperior temporal gyri) is a receptive aphasia because patients lack auditory comprehension (Wernicke’s should remind you of wordy speech that makes no sense).

511. The treatment of epicondylitis includes the following: A. Absolute rest with no activity B. Ice massage for 20 minutes, three times a day in the acute stage and the use of heat during acute or subacute stages C. Weekly steroid injections D. Stretching regimen to gain length in the extensor supinator muscle mass E. Strengthening with gradual concentric, as well as eccentric exercises
511. Answer: E Explanation: A. Selecting rest preferably will avoid stressful activity until the pain has subsided. However, pain free movements are encouraged. Excessive activity or early return to activity may direct excessive stress to healing scar tissue. Activities that involve strong, repetitive grasping, such as hammering or tennis playing, should be restricted until there is minimal pain on resisted isometric wrist extension and little or no pain when the tendon is passively stretched. In the acute stage, the total rest may be achieved by immobilization of the wrist, hand, and fi ngers in a resting splint. However, the splint may be removed several times a day, so that the patient can gently and slowly actively move the wrist into fl exion, the forearm into pronation, and the elbow into extension to maintain the muscle and tendon extensibility. B. Ice massage for 20 minutes is recommended. Elevation and compression are not necessary because appreciable swelling does not occur. C. Steroid injections are recommended if all other modalities of treatments fail. However, these are administered with the intent of providing pain relief only to allow progressional rehabilitation effort. Thus, some believe that healing may occur through rehabilitation but not from steroid injection. However, there is no evidence to prove or disprove this assumption. D & E. Strengthening and stretching regimen is recommended. Other treatment modalities include: - High-voltage galvanic stimulation - Gradual return to activity - Anti-infl ammatory medications - Local anti-infl ammatory treatment - Iontophoresis or phonophoresis with hydrocortisone cream and dy lidocaine or dexamethasone injection may also be helpful.

513. A 52-year-old nurse has a history of low back pain for 2 months. She states the pain started after she lifted a heavy patient at work. It is a nagging pain that worsens with bed rest. She has tried nonsteroidal antiInfl ammatory agents without any relief and has continued to work. She has a past medical history signifi cant for breast cancer 8 years ago and, except for a recent 10-lb weight loss, has been well since her lumpectomy. Her neurologic exam and straight-leg raising test are normal. The rest of her physical examination is unremarkable. Which of the following is the most likely diagnosis? A. Lumbosacral strain B. Metastatic breast cancer C. Disk herniation of L5-S1 D. Spondylolysis E. Spondylolisthesis
513. Answer: B Explanation: Lower back pain is a very common complaint. The differential diagnosis includes soft tissue problems (muscles and ligaments), disk problems (prolapse), facet problems (degenerative joint disease), spinal canal disease (spinal stenosis), and vertebral body diseases (osteoporosis causing a compression fracture, infection, metastatic disease, spondylolisthesis). A. A lumbosacral strain is an injury to a ligament or muscle; it may mimic disk disease, but the neurologic exam and straight-leg raising test generally remain normal. B. Even though radiologic studies are needed to make a defi nitive diagnosis, the leading diagnosis with her history of breast cancer and weight loss is metastatic disease to the lumbosacral area. Pain made worse by lying down or at night may be a sign of malignancy or infection. C.

514. Renal changes in the kidney in a patient with diabetes mellitus of 30 years duration may result in which of the following: A. Decreased permeability to plasma proteins B. Enhanced selectivity of the fi ltration barrier C. Hyperalbuminemia D. A generalized increase in osmotic pressure E. Compensatory secretion of aldosterone
514. Answer: E Explanation: (Kumar, 6/e, pp 446, 570. McKenzie and Klein, p 341. Junqueira, 9/e, p 362.) In patients who have suffered from diabetes mellitus for many years there is compensatory release of aldosterone. The initial change is the thickening of the glomerular basement membrane. The separation of laminae rarae and densa is obliterated, which results in a loss of selectivity of the fi ltration barrier. This causes the loss of protein from the blood to the urine (proteinuria). The liver adjusts to the proteinuria by producing more proteins (e.g., albumin). After continued proteinuria, the liver is unable to produce suffi cient protein, which results in hypoalbuminemia. This leads to an overall decrease in osmotic pressure. The result is edema as fl uid leaves the vasculature to enter the tissues. The movement of fl uid from the vasculature to the tissues results in reduced plasma volume and decreased glomerular fi ltration rate (GFR). The overall effect is further edema because of compensatory release of aldosterone coupled with reduced GFR and the already existing edema. These renal changes are known as nephrotic syndrome. The foot processes are affected in many diseases, such as diabetes mellitus, that lead to nephrotic syndrome. Loss of anionic charge and fusion of the foot processes result in the obliteration of the fi ltration slits. Source: Klein RM and McKenzie JC 2002.

518. A 70-year old man complains of severe back pain in the region of L3/4, with gradual worsening of the back pain with radiation into the lower extremity up to the knee joint. This patient received interlaminar epidural steroid injection for spinal stenosis at L3/4. The most likely diagnosis in this patient is: A. Epidural abscess B. Anterior spinal artery syndrome C. Discitis D. Cauda equina syndrome E. Epidural hematoma
518. Answer: A Explanation: A. Epidural abscess is an extremely rare complication following epidural steroid injections. However, symptoms from an epidural abscess may not become apparent for several days after injection has been administered. The symptoms of epidural abscess include severe back pain, sensory disturbances, and motor weakness.Infections occur in 1% to 2% of spinal injections and range from minor to severe conditions such as meningitis, epidural abscess, and osteomyelitis. One case of discitis following caudal epidural steroid injection also has been reported. Severe infections are rare and occur between 1 and 1,000 and 1 in 10,000 spinal injections. Poor sterile technique is the most common cause of infection. Staphylococcus aureus is the most common infectious organism and is contracted from skin structures. Epidural abscess presents with severe back pain, fever, and chills with a leukocytosis developing on the third or fourth day following the injection. Patients with diabetes or other immunocompromising conditions are more susceptible to infection. Epidural abscess requires emergent surgical drainage to avoid neural damage or other complications. B. Anterior spinal artery syndrome due to damage to the anterior spinal artery or the feeding artery, the artery of Adamkiewicz, leads to ischemia in the thoracolumbar region of the spinal cord. This syndrome is characterized predominantly by motor weakness or paralysis of the lower extremities. C. Discitis from epidural steroid injections is extremely uncommon. However, there has been a case report of this following a caudal epidural steroid injection. Usually, discitis from lumbar discography involves a gramnegative arrow, is self-limited, and resolves with early recognition and administration of appropriate antibiotics. Symptoms are related to back pain and leukocytosis. The most common organisms infecting the lumbar disc or staphylococcus aureus and staphylococcus epidermatitis. Discitis usually presents as an increase in spine pain 5 to 14 days following discography. Acutely, no change in the patient’s neurological status should be evident. An elevated sedimentation rate will be seen within the fi rst week to 10 days. Magnetic resonance imaging is now considered the gold standard in the detection of discitis, which was found to be superior to bone scan with 92% sensitivity, 97% specifi city, and a 95% overall accuracy. D. Cauda equina syndrome may be seen with trauma, lumbar disc herniation, compression of tumors, or in ankylosing spondylitis. The only absolute surgical indication for lumbar disc herniation is the cauda equina syndrome. This syndrome is characterized by bilateral lower extremity weakness and pain, saddle anesthesia, urinary retention, and diminished rectal tone. E. Signifi cant epidural bleeding may cause the development of an epidural hematoma. Clinically signifi cant epidural hematomas are rare and have a reported incidence of less than 1 in 4,000 to 1 in 10,000 lumbar epidural steroid injections. however, they may lead to irreversible neurologic compromise if not surgically decompressed within 24 hours. Retroperitoneal hematomas which may occur following spinal injections if the large vessels are inadvertently penetrated, usually are self-limited but may cause acute hypolemma or anemia. Epidural hematoma as an acute onset of symptomatology with rapidly progressing neurological dysfunction. An immediate physical examination followed by a CT or MRI scan is essential for patients thought to have an epidural hematoma, because early surgical intervention can limit or even prevent permanent neurological damage.

519. An 18 year old girl presents with frequent headaches, each lasting for several days. She has to take time off from school. She describes them as throbbing, localized to the temporal region. They are associated with nausea and vomiting, sensitivity to sound and light. A recent MRI was normal. A diagnostic lumbar puncture done was normal. The most probable cause of her headaches is: A. Migraine without aura B. Post dural puncture headache C. Tension type headache D. Temporal arteritis E. Trigeminal Neuralgia
519. Answer: A Explanation: According to the International Headache Society, headaches are classifi ed into primary and secondary headache disorders. The primary headache disorders consist of: 1.Migraine with aura 2.Migraine without aura 3.Tension type headache - chronic and episodic 4.Cluster headache - chronic and episodic Primary headaches such as migraine with or without aura, tension-type, and cluster headache constitute about 90% of all headaches Migraine as defi ned by the International Headache Society is – Idiopathic, recurring headache disorder manifesting in attacks lasting 4 to 72 hours. A. Diagnostic Criteria for Migraine With and Without Aura Migraine Without Aura i. At least fi ve attacks fulfi lling II-IV. ii. Headache attacks lasting 4-72 h (untreated or unsuccessfully treated). iii. Headache has at least two of the following characteristics: 1.Unilateral location. 2.Pulsating quality. 3.Moderate or severe intensity (inhibits or prohibits daily activities). 4.Aggravation by walking stairs or similar routine physical activity. iv. During headache at least one of the following: 1.Nausea and/or vomiting. 2.Photophobia and phonophobia. v. At least one of the following: 1.History & physical and neurologic examinations do not suggest headaches secondary to organic or systemic metabolic disease). 2.History and/or physical and/or neurologic examinations do suggest such disorder, but it is ruled out by appropriate investigations. 3.Such disorder is present, but migraine attacks do not occur for the fi rst time in close temporal relation to the disorder. Migraine With Aura i. At least two attacks fulfi lling ii. ii. At least three of the following four characteristics: 1.One or more fully reversible aura symptoms indicating focal cerebral cortical and/or brain stem dysfunction. 2.At least one aura symptom develops gradually over more than four minutes or two or more symptoms occur in succession. 3.No aura symptom lasts more than 60 minutes. If more than one aura symptom is present, accepted duration is proportionally increased. 4.Headache follows aura with a free interval of less than 60 minutes. (It may also begin before or simultaneously with the aura). C. At least one of the following: 1.History & physical and neurologic examinations do not suggest headaches secondary to organic or systemic metabolic disease. 2.History and/or physical and/or neurologic examinations do suggest such disorder, but it is ruled out by appropriate investigations. Such disorder is present, but migraine attacks do not occur for the fi rst time in close temporal relation to the disorder. B. Post dural puncture headaches develop after a dural puncture such as a spinal tap. The pain is usually frontal and occipital. It becomes worse in the upright position and is relieved signifi cantly with lying supine. Some patients develop sixth cranial nerve palsy because of the long intracranial course of the sixth cranial nerve. C. The differentiation between tension-type headache (TTH) and migraine without aura more diffi cult. Very often both headaches coexist. Tension-type headaches are tightening or pressing in character. They are mild to moderate in intensity and are bilateral. Tension-type headache are seldom associated with nausea and in most patients Tension-type headaches are not greatly exacerbated by physical activity. D. Giant cell (temporal) arteritis affects the extracranial vessels of the head and arms. There is tenderness over the scalp. The temporal or occipital arteries are enlarged and tender. They may have visual symptoms including amaurosis fugax, diplopia and blindness. Most patients also have symptoms of intermittent claudication with chewing. A temporal artery biopsy is diagnostic. E. Trigeminal neuralgia presents with typical lancinating, sharp, electric like, stabbing pain. Ref: Drugs for Pain Source: Chopra P, 2004

520. A 67-year old white male presents with back pain, stiffness located in thoracolumbar region with history of dysphagia. Radiographic evidence showed fl owing anterior calcifi cation, along four contiguous vertebrae. The remaining evaluation was normal. The most likely diagnosis is: A. Lumbar facet joint pain B. Lumbar disc herniation C. Diffuse idiopathic skeletal hyperostosis D. Osteoporotic fracture E. Spondylolisthesis
520. Answer: C Explanation: Diffuse idiopathic skeletal hyperostosis, also called DISH, or Forester’s disease is probably a variant of osteoarthritis characterized by exuberant ossifi cation of spinal ligaments. Epidemiology - More common with increase in age - Observed in 10% of spine fi lms in elderly - It is twice as common in men as women - It is more common in Caucasians than African- Americans Etiology: - Unknown, not associated with B27; may be increased in diabetics Signs and Symptoms - Back stiffness in 80% - Back pain in 50% to 60% - Pain is typically thoracolumbar - Dysphagia as a result of large cervical osteophytes in approximately 20% Diagnosis - Flowing anterior calcifi cation along four contiguous vertebrae - Preservation of disc height - No sacroiliac involvement Treatment - Active exercise program to optimize range of motion - Non-steroidal anti-infl ammatory agents - Rarely surgical removal of osteophytes - Role of interventional techniques is not known

523. A previously healthy 36-year old woman presents with a complaint of generalized muscular pain with aching in the left buttock for 1 week, 4 weeks after left transforaminal epidural injection at L5. The pain travels down the back of her leg to the heel and lateral side of her foot to the small toe. She has also noted a progressive numbness in her legs and arms, which has worsened over the week. On examination, walking was very diffi cult and her legs buckled when she stood up. The most likely diagnosis is: A. Postherpetic neuralgia B. Brain tumor C. Hysterical reaction D. Guillain-Barré syndrome E. Epidural abscess
523. Answer: D Explanation: The patient has symptoms consistent with Guillain-Barré acute infl ammatory demyelinating polyneuropathy. Pain is a common early symptom of the disease. The patient may complain of muscular or radicular pain or both, followed by sensorimotor dysfunction. The pain may be severe but usually resolves as the symptoms improve. Presentation of epidural abscess with back pain is 1-2 weeks after injections. Source: Kahn CH, DeSio JM. PreTest Self Assessment and Review. Pain Management. New York, McGraw-Hill, Inc., 1996.

525. A 65 year old man presents with symptoms of pain in the cervical region. He also complains of radiation of his pain along the lateral part of his right forearm He has an MRI of the cervical region with evidence of a herniated disc between the fi fth and the sixth cervical vertebra. The nerve root that is most likely compressed is: A. Fourth cervical nerve root B. Fifth cervical nerve root C. Sixth cervical nerve root D. Seventh cervical nerve root E. Eight cervical nerve root
525. Answer: C Explanation: Disc herniations in the cervical region are relatively less common than the lumbar region. In the cervical region the C5 and C6 and C7 intervertebral disc are most susceptible to herniation. The C6 and C7 intervertebral disk herniation is the most common cervical disk herniations. In the cervical region each spinal nerve emerges above the corresponding vertebra. An intervertebral disc protrusion between C5 and C6 will compress the sixth cervical spinal nerve. There are seven cervical vertebra and eight cervical spinal nerves. These patients characteristically present with pain in the lower part of the posterior cervical region, shoulder and in the dermatomal distribution of the affected nerve root. Source: Chopra P. 2004

``` 526. A pituitary adenoma is likely to result in A. Cushing’s syndrome B. Defi ciency in T3 and T4 C. Diabetes insipidus D. Osteoporosis E. Stunted growth or dwarfi sm ```
526. Answer: A Explanation: (Junqueira, 9/e, pp 380-383, 394, 402-405.) Pituitary adenomas are anterior pituitary specifi c. A corticotrophadenoma would cause increased levels of ACTH and stimulate excessive production of corticosteroids from the adrenal cortex (Cushing’s syndrome). LH and FSHproducing gonadotrophs occur but tend to result in hypogonadism. Somatotropic tumors produce GH and cause giantism. Prolactinomas are the most common form of pituitary adenoma resulting in infertility, galactorrhea (excessive production of milk), and amenorrhea. Diabetes insipidus is caused by absence of vasopressin [arginine vasopressin (AVP)], leading to excretion of a large quantity of dilute fl uid (hypotonic polyuria). Overproduction of parathyroid hormone (PTH) leads to osteoporotic changes, but PTH is not regulated by the anterior pituitary. Source: Klein RM and McKenzie JC 2002.

``` 529. The most common presenting symptom of rheumatoid arthritis is: A. Pain in the small joints of the hand B. Neck pain C. Knee pain D. Low back pain E. Shoulder pain ```
529. Answer: B Explanation: Neck pain is the most common presenting symptom of rheumatoid arthritis (RA). Approximately 50% of the head’s rotation is at the atlanto-axial joint, the rest is at the sub axial cervical spine. The atlanto-axial joint complex is made up of three articulations.The axis articulates with the atlas at the two facet joints laterally and another joint posterior to the odontoid process. A bursa separates the transverse band of the cruciate ligament from the dens. Rheumatoid arthritis affects all three joints. The articulations formed by the uncinate processes also known as the joint of Luschka, are not true joints and do not have synovial membrane. Hence, they are not subject to the same changes as seen in RA. Rheumatoid arthritis is an infl ammatory polyarthritis that typically affects young to middle-aged women. They present with a joint pain and stiffness in the hands. They have a history for morning stiffness. Almost 80% of these patients have a positive rheumatoid factor. Source: Chopra P. 2004

530. A young patient presents with a 6-month history of an aching right arm, which is exacerbated by carrying heavy objects or by raising his arms over his head. No neurologic defi cits were found. There was obliteration of the radial pulse with arm extension and abduction. The most likely diagnosis is: A. Herniated nucleus pulposus B. Brachial plexitis C. Pancoast’s tumor D. Thoracic outlet syndrome E. Neurofi broma of the brachial plexus
530. Answer: D Explanation: Thoracic outlet syndrome may be due to a cervical rib, abnormal fi rst thoracic rib, hypertrophy of the scalenus anterior, abnormal insertion of the scalenus medius, bands in Sibson’s fascia, or costoclavicular abnormalities. There is usually involvement of the subclavian vessels and brachial plexus (most commonly C8-T1). The degree of vascular and neurologic dysfunction is variable. Patients may complain of radicular pain or a poorly localized, deep, aching pain under the arm. Cold weather, lifting heavy objects, working with arms over the head, and repetitive movement may worsen symptoms. Pain may occur for years before any neurologic symptoms or signs develop. Diagnosis is made by physical examination and radiologic studies of the neck and chest. Treatment is conservative if there is no signifi cant vascular or neurologic compromise. (Bonica).

534. A 26-year-old woman presents with the chief complaint of weakness that worsens throughout the day. She especially notices weakness and feeling tired when chewing food. The patient states that she feels strong on arising in the morning but the weakness develops over the course of the day. She also complains of her eyelids drooping and occasional diplopia. Neurologic examination reveals ptosis after 1 min of sustained upward gaze. Which of the following is the most likely diagnosis? A. Lambert-Eaton syndrome B. Botulism C. Myasthenia gravis D. Multiple sclerosis E. Friedreich’s ataxia
534. Answer: C Explanation: A. Lambert-Eaton myasthenic syndrome (LEMS) is a progressive generalized weakness that improves with exercise and is associated with small cell carcinoma of the lung. Ocular bulbar muscles are spared, but patients often have autonomic dysfunction. B. Botulism causes rapid progressive paralysis of the bulbar (dilated pupils) and extraocular muscles and eventually causes skeletal and respiratory muscle weakness. The disorder is caused by ingestion of the exotoxin produced by Clostridium botulinum, which blocks acetylcholine release from nerve terminals. C. Myasthenia gravis is fatigable weakness that primarily affects the respiratory, bulbar, and ocular muscles. The etiology of the disorder is autoimmune, causing destruction of the acetylcholine receptors in the affected muscles. Thymic abnormalities often accompany the disorder, and the Tensilon test (injection of edrophonium, which is an acetylcholinesterase inhibitor) often results in improvement of symptoms.

Pain is increased with walking. She reported that leaning on a shopping cart and using it as support for ambulation was very helpful. The most likely diagnosis is: A. Herniated nucleus pulposus B. Lumbar plexopathy C. Spinal stenosis D. Arachnoiditis E. Severe spondylolisthesis
535. Answer: C Explanation: The patient has lumbar spinal stenosis involving the L5 and S1 nerve roots most prominently. Spinal stenosis is a slowly progressive disease and therefore allows for neural adaptation over time. Shopping cart syndrome is a hallmark of spinal stenosis.

536. An obese woman presents with complaints of anterior knee pain after running. She reported a grinding sensation in her knee, with stiffness and pain in the morning hours that occur following the activity for sitting several hours each day. However, she reported feeling better after she started running or walking. She occasionally experiences a giving away sensation during descent, as if she cannot rely on the affl icted leg. Kneeling is extremely uncomfortable. There is no history of trauma to her knee or back. Family history shows osteoarthritis of both knees and hips in her mother and father. Physical and neurological examination is normal. She had no problems with the other knee except for some grinding sensation. The most likely diagnosis: A. Plica syndrome B. Fat pad infl ammation C. Patellofemoral osteoarthritis D. Retropatellar pain syndrome E. Chondromalacia of the patella
536. Answer: E Explanation: A. Plica syndrome is synovial or embryologic remnants presenting as folds of tissue adjacent to the patella. They are a rare source of pain and dysfunction at the knee and may present a challenge to differentiating from chondromalacia. Synovial plica may prove symptomatic and manifest as knee stiffness following sitting with the knee bent for any length of time. Stiffness may be experienced when attempting to get up out of this position.The key, however, to differentiating from plica and chondromalacia derived pain is by historically determining when the patient experiences pain. Pain during activity is generally seen with patellar tracking of abnormalities such as chondromalacia or patellar instability, whereas pain after activity is typical of infl ammatory disorders such as synovial plica irritation. B. Fat pad infl ammation or fi brosis, is a relatively common problem contributing to inferior knee pain in patients’ who have had previous knee surgery or in those who play sports or engaging vocations that directly traumatize this area. Pain is located immediately adjacent to the patellar ligament and stems from the richly innervated fad pad. If fi brosis is extensive, as it may be following several knee surgeries or severe trauma to this site, the retropatellar tendon bursae, as well as the infrapatellar tendon will eventually scar down to the proximal tibia. C. Patellofemoral osteoarthritis represents the end sequelae of chondromalacia and presents with symptoms similar to chondromalacia. However, the articular surface involvement is more advanced with subchondral bone exposure and often has a poorer prognosis. Unlike chondromalacia, radiographs of patellofemoral osteoarthritis show narrowing of the joint space, sclerosis and spurring. These patellofemoral osteophytes typically form on the marginal areas of the femur and may be palpated during the physical examination and viewed on infrapatellar radiographs. These osteophytes may result in catching and popping sensations from synovial catching, entrapment, and irritation from these bone spurs. Patellofemoral arthritis may show a relatively short onset following traumatic injury or may have a more insidious onset in patients with long-standing patellofemoral complaints. The latter typically occurs in patients who endure abnormal forces to the knee, such as maybe incurred from rough sports or heavy work, over many years. D. Retropatellar pain, pre-parapatellar pain, and patellofemoral stress syndrome all describe an overuse injury characterized by peripatellar pain following acutely or slowly from repetitive knee fl exion-extension activities such as jumping, running or kicking. This type of patellar disorder differs from chondromalacia in that arthroscopy evaluation of the retropatellar surface does not reveal the typical fi brillated cartilage surfaces associated with chondromalacia or degenerative changes following an acute blow to the patella. E. Chondromalacia of the patella is commonly encountered in joggers and long-distance runners and has subsequently been called “runners knee.” Nevertheless, the increasing interest in sports among the general population, patellofemoral pain has been identifi ed as the primary complaint of knee pain. Adolescent females are often susceptible to developing chondromalacia as well as patellofemoral instability. Chondromalacia is literally a pathologic description that means softening of the articular cartilage located along the underside of the patella and is commonly the diagnosis given to patients with anterior knee pain. Chondromalacia is a degenerative process believed to result from excessive loading of articular cartilage lining the patellar facets. Articular cartilage is loaded by compressive forces that may be exceeded resulting in decreased diffusion of nutrients and eventual malacia of the involved facet. Classic physical symptoms of chondromalacia include retropatellar pain, recurrent effusion, retropatellar crepitation, patellofemoral grinding during the knee fl exion or extension, and tenderness upon palpation of the patellar facets.

538. A 33-year-old graduate student complains of low back pain after carrying heavy suitcases on a recent vacation in Europe. Because of his pain, he went to a neurologist in London who recommended bed rest and nonsteroidal anti-infl ammatory agents. After 10 days, the back pain resolved, but the patient comes to see you because of new weakness of his right anterior tibialis. The rest of the physical examination is normal. Which of the following is the most likely diagnosis? A. Nerve root impingement B. Tibial stress fracture C. Anterior compartment syndrome D. Gastrocnemius muscle tear E. Popliteal cyst
538. Answer: A Explanation: A. Lumbar disk herniation may occur after lifting heavy objects. A short period of rest (“unloading the spine”) and nonsteroidal anti-infl ammatory agents may help. If a patient develops signifi cant neurologic defi cit after the initial pain has resolved, the diagnosis is most likely nerve root impingement. B. Tibial stress fractures (shin splints) may occur due to weight-bearing exercises or training errors. These injuries cause anterior tibial pain after exercise but not weakness. C. Anterior compartment syndrome occurring after weight-bearing exercise may cause a neuropraxia of the peroneal nerve, leading to footdrop. D. A gastrocnemius muscle tear usually occurs suddenly after rapid dorsifl exion of the ankle and causes severe midcalf pain. In a few days, the calf characteristically develops a bluish discoloration. E. A popliteal cyst (Baker’s cyst) causes calf pain, swelling, and knee effusion. It is often a complication of rheumatoid arthritis and represents a diverticulum of the synovial sac that protrudes through the posterior joint capsule of the knee. (Source: Goldman, 21/e, p 2187.)

546. Which of the following is true about spinal stenosis A. Spinal stenosis can only be diagnosed if a patient has neurogenic claudication B. Spondylolysis of the pars interarticularis is the most common etiology of spinal stenosis C. Classically, patients develop pain after walking and must stop and stand, in order to obtain pain relief D. Patients typically have relief of symptoms when walking downhill E. Urinary dysfunction is common among patients with spinal stenosis
546. Answer: E Explanation: A subset of patients with spinal stenosis have neurogenic claudication, but most patients present with aching low back and thigh pain. Degenerative arthritic changes of the L4-5 facet joints and spondylosis of the L4-5 disc are the most common etiologies of spinal stenosis. Spondylolisthesis is also associate with these changes. Classically, patients must sit or stoop forward in order to obtain pain relief. Patients with vascular claudication have to stop walking and just stand in order to get relief. Patients have an exacerbation of symptoms when walking downhill, due to relative spine extension. Patients with spinal stenosis frequently have urinary dysfunction, as evidenced by urodynamic abnormalities (Inui Y. Spine 2004; 29(8): 869-873) Source: Shah RV, Board Review 2004

547. A 12-year old boy complains of neck and jaw pain. He underwent tonsillectomy 6 months ago. The pain is exacerbated by swallowing, talking, or turning his head. There was no evidence of infection. The most likely cause of his persistent pain is A. Riedel’s struma B. Eagle’s syndrome C. Ludwig’s angina D. Post traumatic stress disorder E. Infection of tonsillar bed
547. Answer: B Explanation: Eagle’s syndrome, also known as stylohyoid syndrome, occurs after tonsillectomy, rarely. This is secondary to fi brosis developing around an elongated styloid process, impinging on the carotid sheath. It causes pain in the upper neck, jaw, face, ears, sternocleidomastoid, or temporal region. Pain may be exacerbated by swallowing, talking, or turning the head. Surgical removal of the styloid may be necessary Source: Kahn CH, DeSio JM. PreTest Self Assessment and Review. Pain Management. New York, McGraw-Hill, Inc., 1996.

``` 550. A 62-year-old woman complains of limb discomfort and trouble getting off the toilet. She is unable to climb stairs and has noticed a rash on her face about her eyes. On examination, she is found to have weakness about the hip and shoulder girdle. Not only does she have a purplishred discoloration of the skin about the eyes, but she also has erythematous discoloration over the fi nger joints and purplish nodules over the elbows and knees. The most likely diagnosis is: A. Systemic lupus erythematosus B. Psoriasis C. Myasthenia gravis D. Dermatomyositis E. Rheumatoid arthritis ```
550. Answer: D Explanation: This woman presents with proximal muscle weakness and pain and a heliotrope rash about her eyes. The term heliotrope refers to the liliac color of the periorbital rash characteristic of dermatomyositis. This rash surrounds both eyes and may extend onto the malar eminences, the eyelids, the bridge of the nose, and the forehead. It is usually associated with an erythematous rash across the knuckles and at the base of the nails and may be associated with fl at-topped purplish nodules over the elbows and knees. Men with dermatomyositis are at higher than normal risk of having underlying malignancies. Psoriatic arthritis may be associated with reddish discoloration of the knuckles and muscle weakness, but the heliotrope rash would not be expected with this muscle weakness, but the heliotrope rash would not be expected with this disorder. The age of onset for a psoriatic myopathy is also atypical. Similarly, the patient’s rashes are not suggestive of lupus erythematosus, although a myopathy may occur with this connective tissue disease as well. Source: Anschel 2004

554. A 52-year-old man presents with locked-in syndrome. On neurologic examination, the patient is quadriplegic with sensory loss and cranial nerve involvement. He is able to respond to questions using his eyes. Choose appropriate diagnosis: A. Basilar artery stroke B. Middle cerebral stroke C. Anterior cerebral stroke D. Transient ischemic attack E. Posterior cerebral stroke
554. Answer: A Explanation: (Tierney, 42/e, pp 962-963.) Basilar artery stroke causes quadriplegia, sensory loss, and cranial nerve involvement; patients may present with coma or locked-in syndrome. Wallenberg syndrome or lateral medullary syndrome causes an ipsilateral weakness of the palate and vocal cords,ipsilateral ataxia, ipsilateral Horner syndrome, and ipsilateral loss of facial pain and temperature but contralateral loss of body pain and temperature sensation. There is no limb weakness in Wallenberg syndrome. Anterior cerebral stroke causes unilateral leg weakness and sensory loss. Posterior cerebral artery stroke causes an occipital stroke and a homonymous hemianopsia. Middle cerebral artery stroke causes hemiplegia or hemiparesis greater in the arm than the leg, aphasia, unilateral sensory loss, and eyes that deviate to the side of the hemispheric lesion. Patients with lacunar infarcts may present with different syndromes, such as dysarthria and mild hemiparesis (clumsy-hand dysarthria). Lacunar infarcts represent small artery occlusions; hypertension and diabetes are risk factors for these infarcts. Patients in a vegetative state from diffuse cortical damage have spontaneous eye opening and movement without evidence of awareness.

557. A 41-year-old construction worker complains of the sudden onset of severe back pain after lifting some heavy equipment. He describes the pain as being in his right lower back and radiating down the posterior aspect of his right buttock to the knee area. He has no bladder or bowel dysfunction. The pain has improved with bed rest. On physical examination, the patient has tenderness in his lumbar area with palpation. The straight-leg maneuver with the right leg increases the back pain at 80°. The straight-leg maneuver with the left leg also causes thigh pain. Sensation, strength, and refl exes are normal. Which of the following is the most likely diagnosis? A. Nerve root compression B. Paravertebral abscess C. Lumbosacral strain D. Osteoporosis compression fracture E. Paget’s disease
557. Answer: C Explanation: (Tierney, 42/e, pp 793-795.) Since the patient has no neurologic compromise, the most likely diagnosis is back strain. Strain is common in people in their forties. It is exacerbated by activity and improves with rest. A straightleg maneuver is positive for nerve root compression from disk herniation when pain is produced at less than 70° of elevation. Crossover pain (straight-leg maneuver of nonpainful leg worsens pain of involved leg) is also a strong indicator of nerve root compression, but only if pain is produced below the knee. Paravertebral abscess usually presents with fever and tenderness with percussion of the affected back area. Risk factors for osteoporosis include female gender, menopause, lack of activity, slim body habitus, older age, inadequate calcium intake, medications such as corticosteroids, and racial-ethnic background (Asian and northern European descent). Paget’s disease (osteitis deformans) is a slowly progressing disease of bone that may be asymptomatic or may cause bone pain, deformities (such as a large skull or leg bowing), hearing loss, and fractures. It begins in middle-aged men and is thought to be due to an inborn error of metabolism causing the formation of poorly organized bone.

``` 559. A 61-year-old man presents with fl accid paralysis, atrophy, fasciculaions, and hyperrefl exia. Choose correct diagnosis: A. Upper motor neuron disease B. Lower motor neuron disease C. Myelopathy D. Radiculopathy E. Broca’s aphasia ```
559. Answer: B Explanation: (Seidel, 5/e, p 798.) Upper motor neuron (UMN) disease (above the level of the corticospinal synapses in the gray matter) is characterized by spastic paralysis, hyperrefl exia, and a positive Babinski refl ex (everything is up in UMN disease). Lower motor neuron (LMN) disease (below the level of synapse) is characterized by fl accid paralysis, signifi cant atrophy, fasciculations, hyporefl exia, and a fl exor (normal) Babinski refl ex (everything is down in LMN disease). A radiculopathy occurs with root compression from a protruded disk that causes sensory loss, weakness, and hyporefl exia in the distribution of the nerve root. Myelopathy causes severe sensory loss 0 posterior column sensation (position sense and vibration), spasticity, hyperrefl exia, and positive Babinski refl exes. Broca’s aphasia (left inferior frontal gyrus) is a nonfl uent expressive aphasia (Broca’s should remind you of broken speech); Wernicke’s aphasia (left posterior-superior temporal gyri) is a receptive aphasia because patients lack auditory comprehension (Wernicke’s should remind you of wordy speech that makes no sense).

560. A 30-year-old woman with a history of diabetes mellitus presents with a 3-week history of hand numbness that often awakens her from sleep. The symptoms resolve after she shakes her hands for a few minutes. On physical examination, there is no sensory or motor defi cit of her hands but there is a positive Tinel sign. Which of the following is the most likely diagnosis? A. Thoracic outlet syndrome B. Carpal tunnel syndrome C. Dupuytren’s contracture D. Mallet fi nger E. Ganglion
560. Answer: B Explanation: (Seidel, 5/e, p 735.) Carpal tunnel syndrome (CTS) is the most likely diagnosis. It is due to median nerve compression by the transverse carpal ligament. Risk factors for this disorder include diabetes mellitus, pregnancy, hypothyroidism, rheumatoid arthritis, repetitive activity, and acromegaly. The Tinel sign (paresthesias or pain reproduced with percussion of the volar surface of the wrist) and Phalen sign (symptoms are reproduced by holding the wrist in passive fl exion for 1 min)may be positive. Patients may complain of pain in the forearm, the thenar eminence, and the fi rst three digits. Thoracic outlet syndrome usually causes medial arm pain and paresthesia when using the arms. The presence of a cervical rib is a risk factor for this disorder. Dupuytren’s contracture is a fi brotic process of the palmar fascia that causes fi xed fl exion of the ring fi nger. Mallet fi nger is a fl exion deformity of the distal interphalangeal joint and is generally the result of traumatic rupture of the extensor tendon of the distal phalanx. A ganglion is a painless, fi rm cystic mass arising from any joint or tendon sheath. A trigger fi nger may be seen in patients with rheumatoid arthritis. It occurs when an enlarged fl exor tendon sheath passes through the pulleys of the digits, causing locking or catching.

``` 561. A 20-year-old man presents with complaints of pain in the left hip and left proximal femur. The pain has been present for approximately 3 weeks and is increasing in severity. It is worse at night and is relieved by aspirin. There is no history of trauma or previous hip or leg problems. Which of the following is the most likely diagnosis? A. Osteosarcoma B. Paget’s disease C. Osteoid osteoma D. Chondrosarcoma E. Muscle strain ```
561. Answer: C Explanation: (Tierney, 42/e, p 835.) C. A history of pain that increases in severity, worsens at night, and is relieved by aspirin suggests the diagnosis of osteoid osteoma. This benign tumor is more common in males than females,and patients present between20 and 30 years of age. The proximal femur is the most common site for this tumor. Other benign tumors of bone include giant cell tumor (osteoclastoma), osteochondroma, chondroblastoma, and osteoblastoma. A & D. The most common malignant tumors of bone include osteosarcoma (45%), chondrosarcoma (25%), Ewing’s sarcoma (15%), and malignant fi brous histiocytoma. Osteosarcomas commonly involve the distal femur. Chondrosarcomas are seen in older patients (40 to 50 years old). Osteosarcomas may be seen later in life as a complication of Paget’s disease.

562. Duchenne muscular dystrophy is a sex-linked disorder involving the gene responsible for the synthesis of A. Glucose-6-phosphatase B. Hexosaminidase B C. Myosin D. Dystrophin E. Actin
562. Answer: D Explanation: Duchenne dystrophy has been incontrovertibly linked to the gene, located on the X chromosome, that makes dystrophin. The more profound the disturbance of this gene, the earlier the disease becomes symptomatic. The gene for dystrophin has single or multiple deletions in affected children. Women who are probable carriers of the defective gene can be checked for heterozygosity and given genetic counseling. Chorionic villus biopsy at 8 to 9 weeks can determine if a fetus that is at risk for the deletion actually carries it. Source: Anschel 2004

563. The commonest cause of Trigeminal neuralgia symptoms is: A. Infected tooth B. Multiple sclerosis C. Temporomandibular joint disorder D. Compression by the superior cerebellar artery. E. Post Therpetic Neuralgia
563. Answer: D Explanation: The most common cause of trigeminal neuralgia is mechanical compression of the trigeminal nerve as it leaves the pons and traverses the subarachnoid space towards Meckel’s cave. The cross compression is usually by the superior cerebellar artery and may occasionally be by the posterior inferior cerebellar artery, anterior inferior or the vertebral artery. The region of pain in the face corresponds with the region of compression of the trigeminal nerve by the artery. Compression of the rostral and anterior portion of the nerve by the superior cerebellar artery causes pain in the maxillary (V2) and mandibular divisions (V3). Pain in the frontal (V1) division is due to compression of the trigeminal nerve root in its caudal and posterior portions by the anterior inferior cerebellar artery. Multiple sclerosis is not a common cause of trigeminal neuralgia. Dental abscess, infection and temporomandibular joint dysfunction has not been proven to be a cause of trigeminal neuralgia.

``` 564. An 35-year-old man presents with a history of low back pain that awakens him from sleep. He also complains of morning stiffness and decreased mobility. The pain does not improve with activity. Schober test is positive. What is the accurate diagnosis? A. Refl ex sympathetic dystrophy B. Ankylosing spondylitis C. Reiter syndrome D. Hypertrophic osteoarthropathy E. Charcot joint ```
564. Answer: B Explanation: 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. Source: Goldman

She also complains of slight grinding or crunching sensation when actively elevating her right shoulder. She admits that her left shoulder bothers her as well, though not as much as right shoulder. There is no history of injury. Physical examination shows no muscle wasting. There was pinpoint tenderness slightly inferior to the anterior border of the acromion while the shoulder is passively extended. She had a presence of painful resisted external rotation and abduction, as well as during passive internal rotation while the shoulder is elevated to 80°. The most likely diagnosis is: A. Impingement of supraspinatus tendon B. Rotator cuff syndrome C. Bicipital tendonitis D. Cervical spondylosis E. Acromioclavicular joint arthritis
567. Answer: A Explanation: The term impingement syndrome was popularized by Charles Neer in 1972 as such. Neer Test for positive impingement sign was popularized by Neer and Walsh which reproduces pain in concomitant fascial grimace when the arm is forcefully fl exed forward by the examiner, jamming the greater tuberosity against the anteroinferior acromial surface. The injection of 10 mL of lidocaine in to the subacromial space, followed by pain relief, helps confi rm the diagnosis and rules out other causes of shoulder pain such as acromioclavicular joint sprain and adhesiocapsulitis which are not relieved by injection.

568. A 14-year-old boy presents with a history of intermittent facial grimacing, twitching, and eye blinking since childhood. The movements are repetitive and often move from one part of the face to another. On physical examination, cranial nerve, sensory, and cerebellar examinations are normal. Motor examination reveals frequent and quick repetitive eye blinking, nasal twitching, and facial grimacing accompanied by an occasional snort or grunt. Which of the following is the most likely diagnosis? A. Tardive dyskinesia B. Tourette syndrome C. Asterixis D. Sydenham’s chorea E. Huntington’s chorea
568. Answer: B Explanation: (Tierney, 42/e, pp 979-982.) Tourette syndrome is a disorder of repetitive progressive multiple tics involving the face, head, and shoulders and is often accompanied by vocal tics (i.e., grunts, snorts, involuntary swearing, or coprolalia). Huntington’s disease is an autosomal dominant disorder characterized by abrupt, involuntary, nonrepetitive, jerky movements (chorea) and dementia. Patients with tardive dyskinesia have developed purposeless movements, such as mouth smacking tongue protrusion, after use of a dopamine-blocking neuroleptic drug. Asterixis is seen in patients with hepatic encephalopathy (liver nap) renal failure and is characterized by frequent inability to sustain wrist extension (bye-bye gesture). Wilson’s disease (hepatolenticular degeneration) is an autosomal recessive disorder of copper metabolism characterized by choreoathetosis, ataxia, cirrhosis, and corneal deposits called Kayser-Fleischer rings. A low serum ceruloplasmin or a high urinary copper level is found in Wilson’s disease. Sydenham’s chorea is seen rheumatic fever.

Which of the following is the most likely diagnosis? A. Arterial insuffi ciency B. Pelvic fracture C. Aortic insuffi ciency D. Aortic dissection E. Compartment syndrome
571. Answer: E Explanation: (Tintinalli, 5/e, pp 1838-1841.) The patient most likely has compartment syndrome from elevated pressure in a confi ned space compromising nerve, soft tissue, and muscle perfusion. Etiologies include burn injuries, crush injuries, and fractures. Compartment syndrome is often referred to as the disorder of Six P’s (Pain, Pallor, Paralysis, Paresthesias, Poikilothermia, and Pulselessness). Immediate fasciotomy and restoration of tissue perfusion is the treatment for compartment syndrome.

582. A middle aged, mildly obese woman presents complaining of bilateral medial right knee pain that occurs with prolonged standing. The pain does not occur with sitting or climbing stairs but seems to be worse with other activity and at the end of the day. The patient denies morning stiffness. Examination of the knees reveals no deformity, but there are small effusions. Some mild pain and crepitus are produced with palpation of the medial aspect of the knees. The most likely diagnosis is: A. Rheumatoid arthritis B. Gouty arthritis C. Chondromalacia patellae D. Osteoarthritis E. Psoriatic arthritis
582. Answer: D Explanation: Osteoarthritis most often affects the weight-bearing joints and is associated with obesity or other forms of mechanical stress. It has no systemic manifestations. It is more common in women, and onset is usually after the age of 50. Pain often occurs on exertion and is relieved with rest, after which the joint may become stiff. Distal interphalangeal joints may be involved, with the production of Heberden nodes. Bouchard nodes are often found at the proximal interphalangeal joint. Crepitus (the sensation of bone rubbing against bone) is often felt on examination of the involved joint. Rheumatoid arthritis is a systemic disease of women under the age of 40. joint involvement is usually symmetric, involving the proximal interphalangeal and metacarpophalangeal joints. Ninetyfi ve percent of gouty arthritis occurs in men and often involves the great toe. Chondromalacia patellae or chondromalacia means softening of the cartilage. Patients present with anterior knee pain and tenderness over the undersurface of the patella. Pain is worse when sitting for long periods of time or when climbing stairs. Psoriatic arthritis is an asymmetric oligoarthritis that involves the knees, ankles, shoulders,or digits of the hands and feet and occurs in 50% of patients with psoriasis. Source: Tierney

585. Which of the following is true of trigeminal neuralgia? A. Like post-herpetic neuralgia, the V1 distribution is the most affected B. Like temporal arteritis, patients typically develop jaw claudication with chewing C. The pain is paroxysmal, shooting and electrical in nature and lasts 10 to 30 minutes at a stretch D. Pain typically lingers between episodes E. Facial muscles innervated by cranial nerve 7 may contract during episodes
585. Answer: E Explanation: (Raj, Pain Review, 2nd Ed., pages 28-39) Trigeminal neuralgia represents painful ectopic or ephaptic fi ring of trigeminal neurons: the ‘kindling’ phenomenon occurs when abnormal impulses in damaged trigeminal neurons are ‘driven’ into a sensory seizure activity by the afferent barrage from trigger zones. Several mechanisms have been proposed. The most common is an abnormal blood vessel, such as the superior cerebellar artery and anterior inferior cerebellar artery. Other mechanisms include demyelinating plaques that affect the caudalis nucleus or direct tumor infi ltration of the rootlets (acoustic neuromas,aneurysms, angiomas,cholesteatomas) A. Unlike PHN, V2 and V3 are the most commonly affected. B. Unlike temporal arteritis, the pain is not gradual and progressive with eating. C. Chewing rather induces paroxysmal, lancinating, electrical shocks that last from seconds to a few minutes (usually less than 2 minutes). D. Patients are usually pain free between episodes. E. Facial muscles may contract during episodes… voluntarily. Patients grimace the face in order to immobilize any trigger zones: tic doloreux. Note hemifacial spasm involves compression or ephaptic discharges of the facial nucleus which can lead to involuntary pain contractions of facial muscles on one side. This is unlike the ‘voluntary’ grimacing of facial muscles with trigeminal neuralgia. Source: Shah RV, Board Review 2005

``` 592.The most common cause of mononeuropathy multiplex is A. Diabetes mellitus B. Temporal arteritis C. Sarcoidosis D. Systemic lupus erythematosus E. Periarteritis nodosa ```
592. Answer: A Explanation: A. Diabetes mellitus is the most common cause of mononeuropathy multiplex. In this disorder, individual nerves are transiently disabled. The neuropathy usually develops over the course of minutes to days, and the recovery of function may require weeks to months. B. Various rheumatoid disease and sarcoidosis produce similar clinical pictures, but temporal arteritis does not typically lead to this type of neuropathy. A vascular lesion is believed to be the most common basis for this type of neuropathy. If the giant cell arteritis seen with temporal arteritis does cause a neuropathy, it is an optic neuropathy with resultant blindness. Unlike the peripheral nerve injuries that develop with mononeuropathy multiplex, this ischemic optic neuropathy of temporal arteritis produces irreversible injury to the affected cranial nerve. The patient who loses vision as part of temporal arteritis does not recover it.

595. Acute pain is never well tolerated, but in which of the following would you expect the patient to have the greatest tolerance? A. Early in the course of the cancer B. Late in the course of the cancer C. After a bone biopsy D. Mucositis following radiation therapy E. Abdominal distention and cramps following chemotherapy
595. Answer: A Explanation: Patients may tolerate high levels of pain early in the course of the illness because of the expectation that anti-cancer therapy may relieve their symptoms.Late in the course they may have increase anxiety, apprehension, and fear. Diagnostic procedures tend to be frequent in these patients. Since patients may be wary of the results and since bone biopsies are frequently painful, this may not be well tolerated. Mucositis is diffi cult to treat and will be unpleasant. Abdominal distention and cramps, along with nausea following chemotherapy would also be poorly tolerated Source: Shah RV, Board Review 2005

596. A patient with inoperable pancreatic cancer has severe abdominal pain. A celiac plexus block failed to provide any relief. Over a period of one month, the patient has required higher and higher doses of fentanyl to150 mcg/hour (two 75 mcg/hr patches). You decide to proceed with an intrathecal trial of morphine in anticipation of placing a permanent intrathecal pump. How much would you trial with? A. 15 milligrams B. 15 micrograms C. 30 milligrams D. 30 micrograms E. 500 micrograms
596. Answer: E Explanation: Typically the conversion ratios for different routes are as follows: Oral to intravenous = 3:1 Intravenous to epidural = 10:1 Epidural to intrathecal = 10:1 Also, although debatable, fentanyl to morphine the conversion ratio is 1:100. Thus, an appropriate trial would start with 0.5 mg or 500 micrograms. The issue of management is controversial, since most patients with inoperable pancreatic cancer are not expected to live more than 4-6 months. Intrathecal pumps typically are cost-effective when the life expectancy is greater than 4-6 months. If less than that then consider a tunneled epidural catheter. Source: Shah RV, Board Review 2005

598. A 17 -year-old football player with his foot planted is tackled from the side, causing a forced valgus bending of the knee. On physical examination, there is tenderness over the medial femoral condyle. McMurray test is negative for any palpable clicks. Which of the following is the most likely diagnosis? A. Tear of the lateral meniscus B. Rupture of the lateral collateral ligament C. Rupture of the medial collateral ligament D. Dislocation of the patella E. Subluxation of the patella
598. Answer: C Explanation: (Seidel, 5/e, pp 737-738.) The lateral and medial collateral ligaments are on either side of the knee. Forced valgus bending of the knee may rupture the medial collateral ligament (MCL), also called the tibial collateral ligament. This is the most frequently injured ligament of the knee. Patients present with pain over the medial aspect of the knee. Injuries to the MCL may in turn tear the medial meniscus since the MCL is attached to the medial meniscus. Patients with medial mensical tears may complain of locking of the knee in fl exion with activity while walking. Injuries of the lateral (fi bular) collateral ligament cause tenderness over the lateral knee with palpation, but these injuries are not common. Dislocation or subluxation of the patella is due to a great force. Locking is common and the patella is usually displaced laterally. Subluxation reduces by itself, while dislocation requires reduction.

601. When taking the history of a new headache patient, which of the following would not raise your suspicion of a serious pathologic etiology? A. Headache that is always in one spot B. Relief of headache with sleep C. Double vision with lateral gaze D. Headache that worsens when lifting a heavy object E. The worst headache ever
601. Answer: B Explanation: (Raj, Pain Review, 2nd Ed., page 25, Table 5-1) Several factors in a targeted headache history should raise concern: New headache of recent onset (‘the fi rst’) New headache of unusual severity Headache associated with systemic illness Headache that peaks rapidly Headache associated with exertion Focal headache Sudden change in a previously stable headache pattern Headache associated with a Valsalva maneuver Nocturnal headache In this case, a headache that is in one spot may be associated with malignancy or other intracranial pathology. Double vision with lateral gaze implies a neurological abnormality, such as increased intracranial pressure. Headache that worsens with heavy lifting implies increased pain with transient increases in ICP (Valsalva). The worst headache ever may signal a catastrophe such as an aneurysm rupture or meningitis. Relief of headache with sleep is often associated with a benign process. Source: Shah RV, Board Review 2005

``` 604. Pain referred to the right side of the neck and extending laterally from the right clavicle to the tip of the right shoulder is most likely to involve the A. Cervical cardiac accelerator nerves B. Posterior vegal trunk C. Right intercostal nerves D. Right phrenic nerve E. Right recurrent laryngeal nerve ```
604. Answer: D Explanation: (April, 3/e, p 260.) The phrenic nerve, which arises from cervical nerves C3 through C5, mediates sensation from the diaphragmatic pleura and peritoneum, as well as from the pericardium; in addition, it carries motor fi bers to the diaphragm. Therefore, pain from the diaphragmatic pleura or peritoneum, as well as from the parietal pericardium, may be referred to dermatomes between C3 and C5, inclusive. These dermatomes correspond to the clavicular region and the anterior and lateral neck, as well as to the anterior, lateral, and posterior aspects of the shoulder.

607. Answer: A Explanation: The World Health Organization recommends a 3 step ladder for cancer pain management: Step 1: Non-opioid analgesics (Aspirin, NSAIDS, acetaminophen) +/-Adjuvants (medications used in pain management whose primary indication is for another disorder) Step 2: Weak opioids analgesics (Codeine, Hydrocodone, Oxycodone) +/-Non-opioid analgesics Adjuvants Step 3: ‘Strong’ opioids analgesics (Morphine, Hydromorphone, Oxycodone, Fentanyl patch) +/- A. Nalbuphine is a mixed opioids agonist and antagonist that has a limited role in cancer pain for two reasons: ceiling analgesic effect and possible induction of opioids withdrawal in opioids tolerant patients. B. Choline magnesium trisalicylate is a non-acetylated salicylate that has a minimal effect on platelet function and lower rates of GI upset compared to acetylated salicylates C. Hydromorphone is a strong opioid agonist. D. Amitriptyline is a tricyclic antidepressant and adjuvant analgesic that has effi cacy in several neuropathic pain syndromes. E.

608. After biopsy resection of a lymph node in her neck, a 23-year-old woman notices instability of her shoulder. Neurologic examination reveals winging of the scapula on the side of the surgery. During surgery, she probably suffered damage to the A. Deltoid muscle B. Long thoracic nerve C. Serratus anterior muscle D. Suprascapular nerve E. Axillary nerve
608. Answer: B Explanation: Winging of the scapula most often occurs with weakness of the serratus anterior muscle. This is innervated by the long thoracic nerve, whose course starts high enough and runs superfi cially enough to allow injury to the nerve with deep dissection into the root of the neck. The long thoracic nerve is derived from C5, C6, and C7. Winging is elicited by having the patient push against a wall with the hands at shoulder level. With this maneuver, the scapula with the weak serratus anterior will be pulled away from the back and vertical margin of the scapula will stick out from the back. Injuries to the long thoracic nerve are usually unilateral and are often due to trauma or surgical manipulation. Source: Anschel 2004

609. A 45-year-old swimmer presents with a sore right shoulder for nearl 12 months. He was taking nonsteroidal anti-infl ammatory agents throughout this period with minimal relief. Over the last several days, he has developed pain with elevation of his arm above the horizontal and has some loss of passive motion in external rotation and with abduction. The pain is relieved after you inject 2 mL of lidocaine into the subacromial space. Which of the following is the most likely diagnosis? A. Fracture of the surgical neck of the humerus B. Bicipital tendinitis due to snapping C. Cervical radiculopathy due to a herniated disk D. Calcifi c tendinitis E. Frozen shoulder due to a rotator cuff injury
609. Answer: E Explanation: A. Fracture of the surgical head of the humerus is usually seen in the elderly after a fall. Swelling and ecchymosis are visible. B. Bicipital tendinitis may be seen with overuse and trauma, but pain is typically felt over the anterior aspect of the shoulder and palpation of the biceps tendon in the bicipital groove elicits tenderness. Pain produced on supination of the forearm against resistance (Yergason sign) confi rms bicipital tendinitis. Lidocaine injection into the synovial sheath of the long head of the biceps relieves pain. C. Cervical radiculopathy typically results in decreased sensation, strength, and refl exes all matching to one root level of the upper extremity. D. Calcifi c tendinitis is due to calcium deposits in the subacromial region and is especially common in the supraspinatus tendon near its insertion. E. Passive range of motion (ROM) tests are performed by the examiner, while active ROM tests are performed by the patient. Passive ROM tests need not be done if active ROM tests are performed adequately. The loss of passive range of motion indicates a stiffening shoulder (frozen shoulder or adhesive capsulitis). The most likely etiology in this patient would be impingement of the rotator cuff causing infl ammation, degeneration, and possibly a tear. The rotator cuff, which is formed by the SITS tendons of the Supraspinatus, Infraspinatus, Teres minor, and Subscapularis muscles, stabilizes the glenohumeral joint and prevents upward movement of the head of the humerus. Injuries may occur from overhead activities including freestyle and butterfl y-style swimming The drop arm sign may be positive in rotator cuff tear (abduct the arm to 180° and ask patient to bring it down slowly; at 90° the arm will drop quickly due to weakness). An injection of lidocaine often relieves the infl ammation inthe subacromial space in patients with rotator cuff tendinitis and alleviates the symptoms. Source: Goldman

625. The activities exacerbating pain the most in an elderly patient with severe spinal stenosis include: 1. Walking uphill 2. Riding a bicycle 3. Bending forward 4. Walking downhill
625. Answer: D (4 Only) Explanation: Pain from spinal stenosis is caused by narrowing of the spinal canal due to degenerative changes in the joints and discs. This often results in multidermatomal leg pain in one or both legs, buttocks, and low back. Movements that open the spinal canal, such as leaning forward (walking uphill, riding a bicycle), will often decrease the pain. Movements that decrease the size of the spinal canal, such as walking downhill, will increase the pain. Source: Kahn CH, DeSio JM. PreTest Self Assessment and Review. Pain Management.

628. A young man presents with morning back pain and stiffness and tenderess over the sacroiliac joints. The patient denies any previous history of eye or genitourinary problems. On physical examination, there is a diastolic rumbling murmur. The most likely diagnosis in this patient is: 1. Rheumatoid arthritis 2. Sjogren syndrome 3. Reiter syndrome 4. Ankylosing spondylitis
628. Answer: D (4 Only) Explanation: (Tierney, 42/e, pp 825-826.) Ankylosing spondylitis (Marie-Strumpell arthritis) is a chronic and progressive, infl ammatory disease that most commonly affects the spinal, sacroiliac, and hip joints. All patients have symptomatic sacroiliitis. Other symptoms ml, include uveitis and aortitis.Men in the third decade of life are most frequently affected, and there is a strong association with HLA-B27 (900 in white patients. Patients with advanced disease present with a bent over posture. A positive Schober test indicates diminished anterior fl exion of the lumbar spine. Involvement of the costoveretebral joints limits chest expansion and eye involvement may cause an iritis. Patients with Reiter syndrome may present with a history of conjunctivitis, urethritis, arthritis, and enthesopathy (Achilles tendinitis). Aortitis in ankylosing spondylitis may cause aortic insuffi ciency. The AI manifests itself early in the course of the spinal disease and may lead to congestive heart failure.

Resistance of the visual system to involvement 3. Severity of symptoms 4. Duration of the aura and the sequence of neurologic defi cits and headache
648. Answer: D (4 Only) Explanation: 1. As with classic migraine, with basilar migraine women are more susceptible than men. 2. Disturbances of vision are common, the aura usually resolve within 10 to 30 min, and the headache invariably follows, rather than precedes, the neurologic defi cits. 3. The visual change may evolve to complete blindness. 4. The character and severity of neurologic defl ects associated with basilar migraine are distinct. Irritability may develop into frank psychosis. Rather than a mild hemiparesis, the patient may have a transient quadriplegia. Stupor, syncope, and even coma may appear and persist for hours. Source: Anschel 2004

649. A young female in her early 20’s presents with history of facial pain for one week on right side. She describes it as an intense shooting pain that comes and goes. Most likely underlying problem of this patient is: 1. Tolosa-Hunt syndrome 2. Migraine 3. Anterior communicating artery aneurysm 4. Multiple sclerosis
649. Answer: D (4 Only) Explanation: 1. The Tolosa-Hunt syndrome is a presumably infl ammatory disorder that produces ophthalmoplegia associated with headache and loss of sensation over the forehead. - Papillary function is usually spared, and the site of pathology is believed to be in the superior orbital fi ssure or the cavernous sinus. - It is usually not associated with trigeminal neuralgia. 2. Migraine has typical pattern of headaches with or without aura. 3. Anterior communicating artery aneurysm produces symptoms inconsistent with this description. 4. Multiple sclerosis is often associated with trigeminal neuralgia, which is then termed symptomatic trigeminal neuralgia because it occurs ass a symptom of another illness. Other causes of symptomatic trigeminal neuralgia include basilar artery aneurysms, acoustic schwannomas, and posterior fossa meningiomas, all of which may cause injury to the fi fth cranial nerve by compression.

651. A 35-year-old man injured his thoracic spine in a motor vehicle accident 2 years ago. Initially he had a bilateral spastic paraparesis and urinary urgency, but this has improved. He still has pain and thermal sensation loss on part of his left body and proprioception loss in his right foot. There is still a paralysis of the right lower extremity as well. True Statements about his status include: 1. This patient has Brown Sequard (hemisection) syndrome. 2. In this patient, the pain and temperature abnormalities start at one or two segments below the lesion. 3. The posterior column neurons decussate at the medulla. 4. The lateral corticospinal tract decussates at the junction of the midbrain and the medulla
651. Answer: A (1, 2, & 3) Explanation: 1. Hemisection of the spinal cord results in a contralateral loss of the pain and thermal sensation due to spinothalamic damage, and ipsilateral loss of proprioception due to posterior column damage. There is also an ipsilateral motor paralysis due to destruction of the corticospinal and rubrospinaltracts as well as motor neurons. Complete transection of the spinal cord would cause a bilateral spastic paralysis, and there would be no conscious appreciation of any cutaneous or deep sensation in the area below the transection. Posterior column syndrome would result in a bilateral loss of proprioception below the lesion, with relative preservation of pain and temperature sensation. Syringomyelic syndrome results from a lesion of the central gray matter. Pain and temperature fi bers that cross at the anterior commissure are affected, which may result in bilateral loss of these sensations over several dermatomes. However, tactile sensation is spared. The most common cause of this type of syndrome is syringomyelia. Trauma, hemorrhage, or tumors are other possible etiologies. If the lesion becomes large enough, then other spinal cord systems affected as well. Tabetic syndrome results from damage to proprioceptive and other dorsal root fi bers. It is classically caused by syphilis. Symptoms include paresthesias, pain, and abnormalities of gait. Vibration sense is most affected. 2. The spinothalamic system is responsible for pain and temperature sensation.It enters the spinal cord through the dorsal root ganglion. The second-order neurons then ascend one or two levels as they cross in the anterior gray commissure. Thus a lesion of the right spinothalamic tract at the T8 spinal cord level would result in a contralateral loss of pain and temperature on the left body beginning at approximately T9-10 dermatome. 3. After the primary sensory fi ber enters the spinal cord, the ascending branch enters the dorsal columns and travels to the medulla. The fi bers from the legs and trunk level medially in the fasciculus gracilis, while those from the arm and neck travel laterally in the fasciculus cuneatus. These fi rst-order neurons synapse in the medulla, and then the second-order neurons decussate as the internal arcuate fi bers and ascend in the medial lemniscus. The secondorder fi bers synapse in the ventroposterolateral nucleus of the thalamus, which then synapses on the somatosensory cortex. 4. The lateral corticospinal tract originates primarily in the precentral gyrus (primary motor cortex). These axons then travel in the posterior limb of the internal capsule, and then the middle section of the cerebral peduncle. They enter the basal pons and continue as the pyramids in the medulla. At the decussation of the pyramids, the lateral corticospinal tract crosses and then continues down the spinal cord. Source: Anschel 2004

652. Answer: C (2 & 4) Explanation: 1. The cortex and marrow do not receive nociceptive fi bers. 2. Bone is innervated by A-delta and C fi bers that form a plexus around the periosteum and invest the cancellous bone. 3. Bone is said to have the lowest pain threshold of the deep somatic structures. 4. Bone is innervated by A-delta and C fi bers that form a plexus around the periosteum and invest the cancellous bone.

669. Answer: D (4 only) Explanation: Hemophilia A and B are X-linked (hence, affecting almost exclusively males), congenital bleeding disorders. Type A is associated with low factor VIII levels. Type B is associated with low or defi cient factor IX levels. Hemophiliacs can develop hemorrhages that develop hours or days after a trauma.Hemorrhage can occur in any organ, but commonly affl ict weight bearing joints, soft tissues, or muscles. Recurrent hemarthroses lead to chronic joint arthritis or ankylosis. This can occur in type A or B. Primary therapy consists of factor replacement. Desmopressin can be used in Hemophilia A. to boost factor VIII levels. Other pain therapy includes acetaminophen and opioids. Opioids should not be given subcutaneously or intramuscularly. Avoid NSAIDs due to their anti-platelet effects. Non-invasive strategies such as biofeedback and TENS should be explored. Source: Shah RV, Board Review 2005

689. Answer: E (All) Explanation: Acute polio starts with a non-specifi c viral syndrome, during which time the virus replicates in the nasopharynx and gut. A viremia develops and gives rise to sore throat, headache, nausea, vomiting, and abdominal pain lasting a few days. Patients may have signs that mimic meningitis. Only 1-2% of cases develop a partial or complete paralytic illness due to viral infection of the anterior horn cells. Up to 50% of the anterior horn cells infected with the virus undergo cell death, whereas the remainder are dysfunctional. Some patients recover, but may develop symptoms later. This condition is thought to be post-polio syndrome. The above criteria of post-polio syndrome were developed at the NIH and should be met before a patient is classifi ed as having post-polio syndrome. Source: Shah RV, Board Review 2004

691. Glossopharyngeal neuralgia 1. may be associated with bradycardia 2. is associated with lancinating pain at the base of the tongue, posterior pharynx, and tongue 3. microvascular decompression may be successful in some cases 4. is an exclusively idiopathic neuropathic pain condition
691. Answer: A (1,2, & 3) Explanation: (Shah, Pain Practice 2003; 3(3): 232-237) Glossopharyngeal neuralgia may be idiopathic or secondary to injury.It is associated with lancinating pain at the base of the tongue, tonsillar fossae, posterior pharynx, and ear. Microvascular decompression is the most successful surgical procedure for the idiopathic variety, as compared to other surgical techniques: neurectomy. Since the vagus nerve is intimately related to the glossopharyngeal nerve, this syndrome may be associated with bradycardia and hypotension. In fact, during radiofrequency procedures,bradycardia is a potential hazard Source: Shah RV, Board Review 2004

692. True statements regarding sickle cell disease include: 1. Valine is substituted for glutamic acid in the sixth acid of the beta chain of hemoglobin 2. With proper treatment, patients with homozygous sickle cell disease have a normal life expectancy 3. Homozygous patients have all HbS, with a variable amount of HbF (fetal globulin) 4. Splenectomy and hematinics have been shown to be effective in prolonging life expectancy and decreasing frequency of crises in patients with severe sickle cell disease
692. Answer: B (1 & 3) Explanation: Sickle cell disease is a chronic hemolytic anemia. It occurs primarily in the black population because of genetic transmission of a molecular lesion of hemoglobin. - 0.15% of black children are homozygous for this trait and manifest symptoms of sickle cell disease. - Diagnosis of the disease is made by history, physical examination, and blood electrophoresis. 1. Valine is substituted for glutamic acid at the sixth position in the beta chain of hemoglobin. - The sickle hemoglobin is fragile and thereby less able to withstand the trauma of circulation, infection, and dehydration. 2. Patients with sickle cell disease suffer from recurrent, painful vaso-occlusive attacks, which may result in progressive infarction of the liver, spleen, gallbladder, and lungs. - Complications associated with these crises lead to shorter life expectancy. 3. Homozygotes have almost all HbS with a variable amount of HbF (fetal hemoglobin). They have no HbA. - Heterozygotes, patients with sickle cell trait, have more HbA than HbS, and as such will not experience hemolysis, painful crises, and thrombotic complications associated with sickle cell disease. 4. Therapy consists of symptomatic treatment. Splenectomy and hematinics are not helpful.

693. A woman in her sixties complains of recent onset of unilateral temporal headaches. She has muscle and joint aches without neck stiffness. She also complains of loss of appetite, low-grade fever, and visual disturbances. The most likely diagnosis is: 1. Migraine headaches 2. Subarachnoid hemorrhage 3. Venous thrombosis 4. Giant cell arteritis
693. Answer: D (4 Only) Explanation: The Diagnosis is Giant cell arteritis The prevalence of giant cell arteritis (temporal arteritis) increases after age 50 and occurs twice as often in women. Patients complain of temporal headache of a constant, boring quality, which may be relieved with aspirin. They may also have symmetric arthralgias and myalgias, general malaise, anorexia, low-grade fever, claudication of jaw muscles, and visual loss due to ischemia of the optic nerve and retina. Facial and temporal artery pulsations may be absent. Blindness and stroke have occurred. Patients with giant cell arteritis also have an increased ESR. The diagnosis is confi rmed by temporal artery biopsy. Treatment is with corticosteroids. In the presence of intolerable side effects, azathioprine has been used with some success. Patients should be on the lowest dose of medication that will suppress the ESR, which should be checked regularly. Rise in the ESR may indicate potential relapse. Source: Kahn CH, DeSio JM.

703.What are the true statements regarding carpal tunnel syndrome? 1. In Phalen’s test or Tinel’s sign, the median nerve is easily depolarized when mechanically stimulated by direct tapping over the palmaris longus tendon over the fl exor retinaculum. 2. Positive fi ndings are present in over 90% of all cases. 3. Intercarpal pressure is greatest at 90° wrist fl exion superimposed on ulnar deviation. 4. Pronator syndrome presents with identical symptoms as carpal tunnel syndrome with similar fi ndings on the nerve conduction studies.
703. Answer: B (1 & 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 carpaltunnel 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 motor branches. 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. 1. 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. 2. Positive fi ndings occur only in approximately 45% of all cases. 3. Intercarpal pressure is greatest at 90° wrist fl exion superimposed on ulnar deviation. 4. 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.

714. Which of the following distinguishes Raynaud’s disease from Raynaud’s phenomenon? 1. Raynaud’s disease is a progressive disorder that leads to irreversible digital gangrene requiring amputation 2. Both manifest symptomatology whereby the digits become white, blue, and then red-in this order 3. Only Raynaud’s phenomenon responds to a sympathetic block 4. Raynaud’s disease is a primary idiopathic disorder which can present bilaterally, whereas Raynaud’s phenomenon is typically secondary to an underlying disease process and unilateral
714. Answer: C (2 & 4) Explanation: (Raj, Pain Review 2nd Ed., page 30) Raynaud’s disease is a relatively common clinical problem characterized by vasospasm of the microcirculation of the fi ngers and is not due to any other pathologic process. Raynaud’s phenomenon is usually secondary to an underlying disease process, but the symptomatology is similar. Raynaud’s phenomenon is typically unilateral and the disease is typically bilateral. Both processes are reversible when a sympathetic block is used or if patients avoid the triggering stimulus, e.g., keeping the hands warm. Although skin necrosis may develop, patients don’t typically develop digital gangrene. The color changes may be found in both conditions: white-vasospasm, bluecyanosis, red-reperfusion and vasodilatation. Source: Shah RV, Board Review 2005

715. Neuralgic pain differs from nociceptive pain in that it usually 1. has a delayed onset after a causative event 2. less responsive to opioid administration 3. has a dysesthetic component to it 4. can be treated by proximal surgical interruption
715. Answer: A (1, 2, & 3 ) Explanation: Neural (neurogenic) pain differs from nociceptive pain in several ways. Typically, its onset is delayed after a causative event and it is often causalgic or dysesthetic in nature. Neurogenic pain may respond to intravenous administration of barbiturate-like drugs but less response to opiates. It is usually temporarily relieved by proximal local anesthetic blockade but not permanently relieved by surgical interruption at the same site. Source: Kahn and Desio

721. True statements with regards to spinal stenosis causing low back and lower extremity pain include the following: 1. Pathophysiology includes narrowing of the spinal canal with disc, osseous thickening of bone, facet joints, or spondylolisthesis 2. Narrowing of the spinal canal with thickening of the ligamentum fl avum, association with DISH or Paget’s disease 3. Venous congestion of the roots of the cauda equina 4. Clinical defi nition of neurogenic claudication includes pain relieved by standing or walking
721. Answer: A (1, 2, & 3) Explanation: Spinal stenosis: narrowing of the spinal canal. Neurogenic claudication: radiating pain or paresthesia into buttocks and lower extremities. Pain exacerbated by standing or walking Pain relieved by lumbar fl exion Radiologic evidence of spinal stenosis Central stenosis defi ned by sagittal diameter of less than 11 mm Lateral recess stenosis-lateral to the central canal with a depth of less than 3 mm Pathophysiology: narrowing of the spinal canal Speculation of venous congestion of the roots of the cauda equina History: Slowly progressive increase in back and unilateral and bilateral legs. Symptoms are relieved by lumbar fl exion and/or sitting. Increase in symptoms walking downhill due to increased lumbar extension. Shopping cart syndrome Important to differentiate from peripheral vascular disease by the need to have sit or bend forward to relieve symptoms or the ability to tolerate cycling with neurogenic claudication. Physical Examination Diffi cult to stand upright and knees are bent slightly forward. Loss of lumbar lordosis Neurological examination may be normal but ankle jerks may be absent Straight leg raising is often normal.

722. Which of the following regarding phantom limb pain are true? 1. Pain increases with time after amputation. 2. The incidence of phantom pain is less than 10%. 3. Pain is more common with distal amputations 4. Phantom pain is not infl uenced by age or gender
722. Answer: D (4 Only) Explanation: Phantom limb pain is a term used to describe painful sensations that are perceived to originate in the amputated portion of the extremity. In addition, patients may have localized pain following the amputation that originates from the stump itself. 1. Phantom limb pain has been reported to occur as early as 1 week after amputation. Generally, the incidence decreases with time. However, 60% of the amputees may experience pain 6 months after amputation. In the fi rst month following amputation, 85% to 97% of patients experience phantom limb pain. One year after amputation, approximately 60% of patients continue to have phantom limb pain. Even though, phantom limb pain may begin months to years after amputation, pain starting more than 1 year following amputation occurs in less than 10% of the patients. 2.The incidence of phantom limb pain is higher than 10%. Early literature reports the incidence of phantom limb pain in amputees to be less than 10%. However, it is now believed that this fi gure is artifi cially low because of the reluctance of patients to report phantom limb pain. Large studies have shown the incidence of phantom limb pain to be 72% to 85%. 3. The incidence of phantom limb pain increases with more proximal amputations. For example, it was reported that phantom pain existed in 68% after hemipelvectomy, 40% after hip disarticulation, 19% after above knee amputation, and 0% with below knee amputation. 4. Phantom limb pain is not infl uenced by age or gender. There is no genetic predisposition toward phantom limb pain, and there is no evidence that learned behavior infl uences the incidence of it. Some studies suggest that it may be less prevalent in the diabetic population. Further, a predisposition to phantom limb pain has been shown in patients of lower socioeconomic class and in those with postoperative wound complications or frozen joints.

724. The true statements regarding endometriosis are as follows: 1. Is commonly felt in the hypogastric region 2. May be resolved with NSAIDs 3. May result from a direct action on nerve endings 4. May mimic acute appendicitis
724. Answer: E (All) Explanation: Endometriosis can cause pain and tenderness by direct action on nerve endings or by interfering with the function of involved or adjacent organs. The pain is characteristically worse a few days before menstruation rather than during the early period of fl ow. Hypogastric midcycle pain (mittelschmerz) in patients with endometriosis can be severe for a few hours to days and canmimic the pain of acute appendicitis.

730. Which of the following are true about tension-type headache? 1. They are always bilateral 2. They typically occur from 11pm to 3 am 3. There is a male predominance 4. Patients typically have a band-like tightness around the scalp
730. Answer: D (4 only) Explanation: (Raj, Pain Review, 2nd Ed., page 27) The typical patient profi le of tension-type headache: - Usually bilateral, but can be unilateral - Possible bandlike, non-pulsatile ache or tightness in the frontal, temporal, and occipital region - Often has neck etiology…hence the associated term cervicogenic headache - Evolves over a period of hours to days and lingers; hence unlike a migraine-which by defi nition is an intermittent headache-tension headaches tend to be present all the time until the exacerbating factors are removed. Exacerbating factors include physical and psychological stress. TMJ and cervical spine disorders can also trigger a headache - No aura - Sleep disturbance is usually present - Female predominance - No hereditary pattern Source: Shah RV, Board Review 2005

734. Causes of scrotal pain include: 1. Testicular cancer 2. Epididymo-orchitis 3. Testicular torsion 4. Paraphimosis
734. Answer: A (1, 2, & 3) Explanation: Scrotal pain or pain in the inguinal area is often associated with pathology of the testicle or epididymis. A careful history and physical examination should be performed to rule out acute conditions such as testicular torsion, infection of the epididymis or testicle, and fracture of a portion of the testicle after trauma. Testicular cancer is most common in men 20 to 40 years of age. Urinalysis will provide information regarding infl ammatory or infectious causes of pain. If examination of the testicle reveals that it is elevated in the scrotum close to the external inguinal ring, torsion exists and may be a surgical emergency. If a portion of the testicle has been fractured in a traumatic event, the painful necrotic portion of the testicle may requirer excision and anastomosis of the tunica albuginea to preserve function of the remaining portion of the testicle. Early testicular cancer is usually nonpainful, but it is frequently associated with epididymitis. After appropriate treatment of the infection/infl ammation, ultrasound and possibly a testicular biopsy should be performed to rule out testicular cancer. Paraphimosis is a condition in which the retracted foreskin forms a constricting band at the base of the glams. This may be associated with penile pain. Source: Kahn CH, DeSio JM.
