Q

What is the approximate percentage of HEAD TRAUMA results in mortality?

What types of damage do we see and what general Sx may appear?

A

~ 50% with severe injury (more deaths & disability than other neuro cause in >50 yo)
- Damage to nerve tissue, blood vessels and meninges can result in neural disruption,
ischemia, hemorrhage and edema

Q

Closed head injuries (emergency or urgency)

A

Eg. acceleration-deceleration injury (whiplash)- local injury and opposite side of skull
“contra-coup injury”
- severity based on:
i) loss of consciousness or not
ii) presence or absence of neurologic signs

Q

Physical Exam for Head Pain.

A
  • Observation: ex. cranial size → hormonal issues
  • Vitals: height and weight every time (weight: chronic disease, particular with wasting; kids, elderly; height: kids, elderly)
  • Palpation of head and scalp: lesions, masses, tenderness; On infants, examine fontanelles
  • Full exam of Ears, Eyes, Nose, Sinus, Throat, Neck
  • Appropriate neurological exams (CN, peripheral, orientation, cognitive) *Review of cranial nerves 1-12

Q

What is a secondary injury?

A

after primary injury: further brain swelling and can lead to secondary brainstem damage and death—from hypotension, hypoxia, infection, hematoma

50
Q

What is a headache?
How common is it?
Where does the pain come from?

A

head or neck pain; may be a disorder in its own right or caused by underlying medical condition

Common! 5 -10% US population seek medical help for headache, 20% kids have significant HA

Brain tissue itself does not have sensory nerves, so headache pain comes from outside the brain (meninges, scalp, blood vessels and muscles)

51
Q

What classifications are used to explain HAs?

A
  1. Primary or secondary

2. Vascular or nonvascular

52
Q

What is a primary HA? Examples?

A

not caused by underlying medical diagnosis
90% of all HAs

Examples: migraine (with or without aura) – primary and vascular; tension-type (episodic or chronic) – primary and non-vascular; cluster

53
Q

What is a secondary HA? Examples/Causes?

A

caused by/accompany underlying medical condition

  • Head and neck trauma – eg. post-concussion syndrome
  • Cranial or cervical vascular disorders – eg. temporal arteritis, hematoma, hemorrhage
  • Nonvascular intracranial disorders - either high CSF pressure (e.g., secondary to tumors) or low CSF pressure; benign intracranial hypertension
  • Infection – eg meningitis or systemic infection
  • Disorders of the cranium, neck, eyes, ears, nose, sinuses, teeth, mouth, etc
  • Disorders of homeostasis - diving, high altitude, hypoxia, hypertension, hypothyroidism, fasting, heat stroke, “sphenopalantine ganglioneuralgia”
  • Substance use or its withdrawal – i. Acute substance use (e.g., nitric oxide, alcohol, food additives, cocaine, cannabis, histamine). ii. Medication overuse headache (e.g., from triptans, analgesics, opioids, combinations). iii Substance withdrawal headaches (e.g., from caffeine, opioids)
  • Psychiatric conditions – eg depression, anxiety disorders, somatization disorders
  • Cranial neuralgia - both trigeminal and glossopharyngeal neuralgias
  • Iatrogenic: lumbar puncture, manipulation, physiotherapy
54
Q

Name of a brain freeze?

A

“Sphenopalantine ganglioneuralgia”

55
Q

What defines a Vascular headache? Examples?

What is the quality of pain?

A

various triggers lead to rapid changes in artery size; from spasm/ constriction. Other arteries in the brain and scalp then dilate, and throbbing pain is perceived in the head

  • Examples: migraine with or without aura, cluster, fever, hypertension, exertion, hangover
  • quality of pain: throbbing or pounding, sharp)
56
Q

What is the quality of pain for a Non-vascular headache? Examples?

A

quality of pain: steady, constant, dull

- Examples: tension-type, TMJ, brain tumor, sinus or dental infection, inner or middle ear

57
Q

RED FLAGS on HA History

A
  • Onset after age 50: temporal arteritis, intercranial mass
  • Incr. frequency and severity: subdural hematoma, mass, medication overuse
  • Sudden onset of headache: subarachnoid hemorrhage, vascular malformation, mass
  • Pain moves to lower neck and thoracic spine: meningial irritation
  • First or worst headache: intercranial hemorrhage, CNS infection
  • History of head trauma: intracranial hemorrhage, subdural hematoma, epidural hematoma
  • History of HIV or cancer: meningitis, brain abscess, metastasis, opportunistic infx
  • Any change in mental status, personality, level of consciousness
58
Q

D. Physical examination for headache

A

vital signs (BP, temp)
head and neck – carotid and temporal artery pulsations
cervical ROM
tenderness of muscles of head and neck
palpate cranium, jaw, neck, sinus
perform oral and ear exam
neurological exam (cranial nerves, motor/sensory, reflexes, coordination)
HEENT exam (opthalmascopic/fundoscopic exam extremely important, to check for papilledema)

59
Q

Red Flags on PE for HA

A
  • Fever: intercranial, systemic or local infection
  • Neck stiffness/rigidity: meningitis
  • Papilledema: meningitis, mass, pseudotumor cerebri, increased intracranial pressure
  • Focal neurological signs
  • Signs of systemic illness or infection: meningitis, encephalitis, lyme dz, systemic infx,
  • collagen vascular disease
60
Q

Describe a Migraine HA.

A

Often familial. Recurrent attacks, variable in intensity, frequency, duration. Usually unilateral and associated with anorexia, nausea and vomiting. Photophobia Aura may or may not occur

61
Q

What are the classifications of Migraine HAs?

A
  • Migraine without aura
  • Migraine with aura
  • Subtypes of Migraine with Aura
62
Q

Impact of Migraine HAs

A

Patient: decreased energy and vitality; decreased social functioning
- 50% of pts miss at least 2 workdays/mo; avg at least 6 days of impaired ability/mo; 43% reduction in performance effectiveness

Family: negative impact on family and partner, eg missed activities

63
Q

Theories/Pathophysiology of Migraine HAs

A

neurovascular, vasoactive neuropeptides (substance P), cortical spreading depression, role of serotonin? genetics? Combination

Poly-factoral means multiple vectors of treatment approaches!

64
Q

Diagnosis of Migraines

A

Mainly through the Medical History—get clear picture and chronology of symptoms –> HA DIARY
Record: Date(s) of attack, what time the attack began, what time the attack ended, any warning signs?, previous few days (activity, triggers), medications/dose taken, symptoms including aura, if present

65
Q

Screening Test for Migraine

A

Self administered 3 question test has >90% accuracy at detecting migraine.

  1. Has a headache limited your activities for a day or more in the last 3 months?
  2. Are you nauseated or sick to your stomach when you have a headache?
  3. Does light bother you when you have a headache?
66
Q

Other Work-up possible: (only to exclude secondary causes)

A 
EEG	
CT and/or MRI
EMG
TMJ radiography
Cervical spine films
CMP
Psychometric testing
67
Q

Diagnostic Criteria for Migraine without Aura (previously termed “common migraine”)

A

at least 5 attacks with the following:
•HA lasting 4-72 hr. (untreated or unsuccessfully treated)
•At least 2 of the following characteristics:
- unilateral location
- pulsating quality
- moderate to severe pain
- worse with routine activity
•During headache at least one of the following occurs:
- nausea and/or vomiting
- photophobia and phonophobia
•History, physical exam, and neuro exam show no evidence of organic dz.

68
Q

Diagnostic Criteria for Migraine with Aura (previously termed “classic migraine”)

A 
at least two attacks of:
Aura includes at least 1 of the following (reversible sx)
•visual - scintillating scotoma (area of loss of vision, irregular luminous patch)
   - photopsia (flashing lights)
•sensory –paresthesia on face
   - numbness
   - unilateral weakness
   - olfactory hallucinations
•dysphasic- speech disturbance (aphasia)

Aura develops over 5-20 min, usu lasting < 60 min.
HA follows during or after aura, lasts 4-72 hr

History, physical exam, and neuro exam show no evidence of organic dz.

May also be prodromal symptoms occurring hours/day before migraine: hyperactivity, lethargy, depression, cravings, frequent yawning
Headache has similar features to above migraine, starting during the aura or w/in 60 min

69
Q

TENSION-TYPE HEADACHE (TTH) Classifications

A
  • Infrequent episodic TTH—headache episodes less than one day a month (30-80% of pop)
  • Frequent episodic TTH—headache episodes 1-14 days a month
  • Chronic TTH—headaches 15 or more days a month (3% of pop)
70
Q

TTH Pathophysiology

A
  • multifactorial
    Heightened sensitivity of pain pathways in CNS and peripheral nervous system.
    Sensitization of dorsal horn neurons due to increases nociceptive imputs from pericranial myofascial tissue. Innocuous stimuli misinterpreted as pain.
    Nitric oxide and genetics may play a role.

73
Q

What is a CLUSTER HEADACHE?

A

neurovascular headache with severe pain attacks which recur daily for prolonged periods

74
Q

Pathophysiology of Cluster HA: Proposed Mechanisms

A

not well understood, some proposed mechanisms include:

a. Hemodynamic: Vascular dilatation may play a role
b. Trigeminal nerve: may be responsible for neuronal discharge causing cluster headaches. Substance P neurons carry sensory and motor impulses in the maxillary and ophthalmic divisions of the nerve.
c. Autonomic nervous system: Sympathetic (e.g., Horner syndrome, forehead sweating) and parasympathetic (e.g., lacrimation, rhinorrhea, nasal congestion) effects occur.
d. Circadian rhythm: often recur at the same time every day, suggesting that the hypothalamus, which controls circadian rhythms, may be the site of activation.
e. Mast cells: Increased numbers of mast cells have been found (inconsistently) in the skin of painful areas of some patients (quercitin is good for this)

75
Q

Diagnostic criteria for Cluster HA from ICHD-2

A

Episodic cluster headache:
- at least 2 cluster periods lasting 7 days to 1 year
- separated by pain-free periods lasting ≥ 1 month

76
Q

Cluster Headache characteristics:

A

• Onset: sudden - peaks in 10-15 minutes; typically awakens a person from sleep 1 to 2 hours after going to bed. “alarm clock headaches” often awaken the person at the same time at night. These nocturnal attacks can be more severe than the daytime attacks.

Q

Acute suppurative rhinosinusitis , S&S and PE

A

Signs & Sxs: >1 week, but < 3 weeks
duration (most improve within 7-10 days so the complaint of persistent or worsening symptoms may indicate a developing bacterial sinusitis.)
nasal congestion, purulent drainage, and facial pain with headache
pain is often exacerbated by leaning forward or any head movement
may have dental pain or altered smell
Kids: may complain of a daytime cough and persistent nasal discharge

Symptoms by involved sinus:

DDX infected tooth
ii. Frontal: tenderness over forehead area, swelling of eyelids, frontal h/a
iii. Ethmoid: pain more medial to eye, feels deep in head or eye, splitting h/a on one side, swelling of eyelids
iv. Sphenoid: pain behind eye or in occiput or vertex, deeper pain, not local tenderness

PE: purulent secretions in the middle meatus (highly predictive of maxillary sinusitis) fever is rare unless bacterial cause. (usu no fever if viral), facial tenderness to palpation or percussion, complete opacification of sinus on transillumination—sinus not patent
partial opacification is a nonspecific finding, and it is not as reliable.
