Headache, Back and Neck Pain Flashcards
(100 cards)
1
Q
HEADACHE
A
• Most common reasons to seek medical attention
• Globally responsible for more disability than other
neurologic problem
• Can be primary or secondary
2
Q
PRIMARY - headache
A
o Caused by overactivity of or problems with
pain-sensitive structures in your head
(Mayo Clinic)
o Isn’t a symptom of any underlying disease
o often results in considerable disability and
a decrease in patient’s quality of life
3
Q
SECONDARY - headaches
A
o a symptom of a disease that can activate the pain-sensitive nerves of the head o mild secondary headaches are seen in association with upper respiratory tract infections
4
Q
Stimulus (peripheral nociceptors)
A
Tissue injury, visceral distention, etc.
o Damaged or inappropriate activation of
PNS or CNS
5
Q
Cranial structures that are pain-producing:
A
o Scalp o Middle meningeal artery o Dural sinuses o Falx cerebri o Proximal segments of large pial arteries
6
Q
KEY STRUCTURES INVOLVED IN PRIMARY HEADACHE
A
• Large intracranial vessels and dura mater
• Peripheral terminals of the trigeminal nerve that
innervate these structures
• Caudal portion of the trigeminal nucleus, which
extends into the dorsal horns of the upper cervical
spinal cord and receives input from the 1st and
2nd cervical nerve roots (trigeminocervical
complex)
• Rostral pain processing region
• Pain modulatory system in the brain that receives
input from trigeminal nociceptor
7
Q
ACUTE NEW ONSET HEADACHE
A
• Potentially serious cause is considerably greater
than recurrent headache
• Signs and symptoms pertain to potentially serious
etiology, wherein there is presence of worrisome
symptoms (being sudden & severe)
• Need prompt evaluation and management
• Complete neurologic examination (1st step)
• Dx/Labs: CT, MRI, lumbar puncture (LP)
• Serious causes include:
o Meningitis
o Subarachnoid hemorrhage
o Epidural or subdural hematoma
o Glaucoma
o Tumor
o Purulent sinusitis
8
Q
FINDINGS OF POTENTIALLY SERIOUS OR WORRISOME
HEADACHES
A
• Worst headache ever • First severe headache • Subacute worsening over days or weeks • Abnormal neurologic examination • Fever or unexplained systemic signs • Vomiting preceding headache • Pain induced by bending, lifting, coughing • Pain that awakens patients or is present upon awakening • Known systemic illness • Onset after age 55 • Pain associated with local tenderness
9
Q
GENERAL EVALUATION OF ACUTE HEADACHE
A
• Investigation of cardiovascular and renal status
o Blood pressure monitoring and urine
examination
• Fundoscopy (presence of papilledema suggests
increased intracranial pressure), intraocular
pressure measurement, and refraction
• Cranial arteries by palpation
• Cervical spine by the effect of passive movement of
the head and by imaging
• Psychological state (comorbidity rather than cause)
o There is a relationship between head pain
and depression.
10
Q
SECONDARY HEADACHE
A
63% - systemic infection (most common) o 4% - head injury o 1% - vascular disorders o <1% - subarachnoid hemorrhage o 0.1% - brain tumor
11
Q
MENINGITIS
A
• Acute (<5 min.), severe (>5 min.) headache
• Fever and stiff neck (suggestive symptoms)
• Accentuation of pain with eye movement
• Pounding headache, photophobia, nausea and
vomiting (easily mistaken for migrain)
• Dx test: LP is mandatory
• Treatment: antibiotics
12
Q
INTRACRANIAL HEMORRHAGE
A
• Acute and severe
• Stiff neck WITHOUT fever
• Secondary to ruptured aneurysm, AV
malformations, or intraparenchymal hemorrhage
• Dx: CT scan and LP may be used for diagnosis
o head CT is normal, if hemorrhage is small
or below the foramen magnum, you can
do a lumbar tap
13
Q
LUMBAR PUNCTURE CONTRAINDICATIONS
A
Increased intracranial pressure is a relative LP
contraindication
• Absolute contraindications
o The presence of infected skin over the needle
entry site and the presence of unequal pressures
between the supratentorial and infratentorial
compartments
14
Q
Characteristic findings on CT of
the brain of LP
A
• Midline shift • Loss of suprachiasmatic and basilar cisterns • Posterior fossa mass • Loss of superior cerebellar cistern • Loss of quadrigeminal plate cistern
15
Q
BRAIN TUMOR
A
• Chief complaint in 30% of patients: HEADACHE
• Intermittent, deep, dull aching pain of moderate
intensity
• Aggravated by exertion or change in position maybe
associated with nausea/vomiting (more in migraine)
• In 10% of cases, headache disturbs sleep
• Vomiting precedes headache by weeks (posterior
fossa brain tumors)
• History of amenorrhea or galactorrhea (prolactinsecreting pituitary adenoma or the polycystic ovary
syndrome)
• Headache arising from a known malignancy (cerebral
metastases or carcinomatous meningitis, or both)
• HA appearing abruptly after bending, lifting or
coughing may indicate presence of posterior fossa
mass, a Chiari malformation, or low CSF volume
16
Q
TEMPORAL ARTERITIS (Giant Cell)
A
• aka Horton’s or giant cell arteritis; Inflammatory
disorder of arteries; Extracranial carotid circulation
• Commonly seen in females age 50 and older
o average age of onset is 70 years, and
women account for 65% of cases
• If left untreated, may lead to blindness due to the
development of ischemic optic neuropathy
• Presents with headache, PMR (polymyalgia
rheumatica), jaw claudication, fever, weight loss
and tenderness with scalp
17
Q
TEMPORAL ARTERITIS (Giant Cell) headache
A
Head pain may be unilateral or bilateral, temporally
located in 50% of cases. Associated with malaise
and muscle aches
• Pain usually appears gradually over few hours
before peak, occasionally explosive and seldom
throbbing
• Almost invariably described as dull and boring and
usually worse at night and often aggravated by
exposure to cold
• Head pain is superficial, external to the skull, rather
than originating deep within the cranium
• Marked degree of scalp tenderness
o brushing of hair or resting the head on a
pillow may be impossible
• Reddened, tender nodules or red streaking of the
skin overlying the temporal arteries, less common
tenderness on occipital arteries
18
Q
TEMPORAL ARTERITIS (Giant Cell) headache Diagnosis
A
Dx: Elevated ESR

associated with other symptoms of neurologic
dysfunction
23
Q
Episodic headache
A
associated with sensitivity to
light, sound, or movement
• Usually accompanied with nausea and vomiting
• Most common headache-related disability in the
world, afflicts 15% of women and 6% of men over a
year
• Have triggers prior to the onset of an attack
• Stimulus could be environmental or sensory
• Sensitivity is amplified in female during menses
24
Q
Triggers for Migrane
A
o Glare, bright lights, sounds, or other afferent stimulation o Hunger o Excess stress o Physical exertion o Stormy weather or barometric pressure changes o Hormonal fluctuations during menses o Lack of or excess sleep o Alcohol or other chemical stimulation
25
PATHOGENESIS of Migrane
```
o Activation of vasoactive neuropeptides
§ Calcitonin gene related peptide
o 5-hydroxytryptamine (5-HT) or serotonin
§ Methysergide can stimulate 5-
HT1B/1D
o Dopamine
o Dopamine receptor hypersensitivity
§ as demonstrated by the induction
of yawning, nausea, vomiting,
hypotension, and other symptoms
of a migraine attack by
dopaminergic agonists at doses
that do not affect non-migraineurs
```
26
Familial Hemiplegic Migraine (FHM)
```
Mutation of voltage-gated calcium channel
CACNA1A gene (FHM1)
o Na+K+ATPase ATP1A2 gene (FHM2) - 20%
of FHM cases
o Neuronal voltage-gated sodium channel
SCN1A
```
27
Associated symptoms of migraine
```
o Nausea
o Photophobia
o Lightheadedness
o Scalp tenderness
o Vomiting
o Visual disturbance
§ Photophobia
§ Fortification spectra
o Paresthesia
o Vertigo
o Alteration of consciousness
§ Syncope
§ Seizure
§ Confusional state
o Diarrhea
```
28
Diagnostic Criteria for Migraine
```
o Repeated attack of headache lasting 4-72h
in patient with normal PE, no other
reasonable cause for the headache and
o At least 2 of the following
§ Unilateral pain
§ Throbbing pain
§ Aggravation by movement
§ Moderate or severe intensity
o Plus at least 1 of the following features
§ Nausea/vomiting
§ Photophobia/phonophobia
o A high index of suspicion is required to
diagnose migraine
§ The migraine aura, consisting of
visual disturbances with flashing
lights or zigzag lines moving across
the visual field or of other neurologic
symptoms (20-25% of patients)
§ Headache diary
• Helpful in making the
diagnosis
• Helpful in assessing
disability and the
frequency of treatment
for acute attacks
```
29
Migraine must be differentiated from
| tension-type headache
§ Migraine headache is headache
with associated features
§ Whereas tension-type headache
that is featureless
30
One third of patient referred for vertigo or
| dizziness have a
primary diagnosis of
migraine known as acephalgic migraine
wherein there is typical aura but without
headache.
31
non-pharma Management/ Treatment of migrane
```
§ Avoidance of triggers
§ Regulated lifestyle
• Healthy diet
• Exercise
• Regular sleep patterns
• Avoid excess caffeine
and alcohol
• Avoid acute changes in
stress levels
```
32
PHARMACOLOGICAL migrane
```
§ NSAID’s
§ 5-HT1 agonist
§ Ergotamine and dihydroxyergotamine
• These are non-selective
receptor agonist
• Comes in oral, nasal,
and IV preparation
• Can induce nausea
• Dosage is 2 mg
§ Triptans (e.g. sumatriptan,
zolmitriptan, almotriptan etc)
• Selective 5-HT1B/1D
agonist
• Not effective in migraine
with aura
• Contraindicate in patient
with cardiovascular and
cerebrovascular disease
§ Dopamine antagonist
• Oral metoclopramide
10mg
• Parenteral (e.g.
chlorpromazine,
prchlorperazine, and
metoclopramide)
• It enhances gastric
absorption
• It decreases nausea
vomiting
• Restores normal gastric
motility
§ Others
• Narcotics
• B-blockers (propranolol
and timolol)
• Topiramate
• Sodium valproate or
gabapentin
• Methysergide
o Migraine can be modified and controlled
but cannot be eradicated
o Migraine is commonly not associated
with serious or life-threatening illness
```
33
Preventive Treatments in Migraine
The probability of success with any one of the
antimigraine drugs is only 50-75%
§ Many patients are managed adequately with
low-dose amitriptyline, propranolol, topiramate,
gabapentin, or valproate but if it fails or lead to
unacceptable side effects, second-line agents
such as methysergide or phenelzine can be
used.
§ Once effective stabilization is achieved, the
drug is continued for 5-6 months and then
slowly tapered to assess the continued need
34
TENSION TYPE HEADACHE
• Chronic head type pain syndrome
• Bilateral tight band-like discomfort
• Episodic or chronic (>15 days per month)

hemicrania, and SUNCT (short lasting unicranial
neuralgiform headache attacks with conjunctival
injection & tearing)

41
Secondary PH
```
Lesions in the sella turcica
§ Av malformations
§ Cavernous sinus meningioma
§ Epirermoid tumors
o Require high doses of indomethacin
(indomethacin reduce CSF)
o Bilateral PH should suspect a raised CSF
pressure
o MRI is indicated to exclude a pituitary lesion
```
42
SUNCT/SUNA

described as stabbing or throbbing in quality
43
Diagnostics of SUNA
```
At least 20 attacks per day
o Duration of 5 to 240 seconds per episode

(short acting unilateral neuralgiform
headache attacks with cranial
autonomic symptoms)
```
44
Pain
o Single stab
o Group of stabs
o Prolonged attack with no refractory or
pain free period (saw-tooth phenomenon)
o Characteristics that leads to a suspected
diagnosis of are the cutaneous triggers of
attacks, a lack of refractory period to
triggering between attacks and nonresponsive to indomethacin
45
Secondary (symptomatic) SUNCT
o Seen with posterior fossa or pituitary
| lesions
46
Treatmen of SUNCT
```
Acute pain
§ Intravenous lidocaine
• This can arrest symptoms but not
useful because of short duration
§ Preventive therapy
• Lamotrigine 200-400 mg/d
• Topiramate and gabapentin
• Greater occipital nerve injection
• Occipital nerve stimulation
```
47

syndromes (chronic TTH, headache secondary to
trauma, inflammation, infection, medication
overuse, and other causes)
• May be primary or secondary
48
Management of CDH
```
o Tapering doses of analgesics
o Use of NSAIDs
o Use of preventive medications
(Preventives generally do not work in the
presence of analgesic overuse)
§ most common cause of
unresponsiveness to treatments
is the use of a preventive when
analgesics continue to be used
regularly
```
49
Management for in-patients
```
Rapid removal of analgesics
o Anti-emetics, fluids

or pelvic, but is accompanied by back pain
and usually unaffected by posture.
o Back pain only.
72
PAIN OF SPINE ORIGIN
```
In the back or referred
to the buttocks or legs.
o Diseases affecting the upper lumbar spine
tend to refer pain to the lumbar region,
groin or anterior thighs.
o Diseases affecting the lower lumbar spine
tend to produce pain referred to the
buttocks, posterior thighs, or rarely the
calves or the feet. It can explain pain
syndromes that cross multiple
dermatomes without evidence of nerve or
nerve root injury.
```
73
RADICULAR PAIN-
sharp and radiate from the
low back to a leg within the territory of a nerve
root. Coughing,sneezing, or voluntary contraction
of abdominal muscles may elicit radiating pain.
Pain may increase in postures that stretch the
nerve root.
74

cause of neck, shoulder, arm, or hand pain or
tingling
• Commonly associated with neck pain, stiffness,
pain limited range of motion
• Commonly affected are C7 and C6

```
96
Other causes
Rheumatoid arthritis • Ankylosing spondylitis o C1-C2 subluxation • Thoracic outlet obstruction o Comprises the first rib, subclavian artery
and vein, brachial plexus, clavicle, and the

intrinsic hand muscles and
diminished sensation at the
palmar aspect of the fifth digit
o Treatment: surgical resection
```
98
Arterial TOS
o Compression of the subclavian artery by a
cervical rib
o Poststenotic dilatation and thrombus
formation
o BP is reduced in the affected limb o Signs of emboli may be present o No neurologic signs o Ultrasound confirms diagnosis o Tx: Thrombolysis or anticoagulant or
surgical resection
99
Venous TOS
o Subclavian vein thrombosis o Swelling of the arm and pain o Dx: Venography
