Jeopardy!!! Flashcards
Result of Weber’s and Rinee’s test in case of conductive hearing loss
Bone conduction greater than air conduction
Webers test would lateralize TO affected side
Perceived as louder in side with conductive hearing loss
Chronic alcoholic findings on exam:
- Both eyes medially deviated in primary position with horizontal nystagmus, inability to move eyes AT ALL when tracking a target except for convergence
- Positive Romberg and unsteady gait
- lack of orientation
Wernicke encephalopathy
Tx: thiamine
Presence of this psychiatric disorder in a 12 year old boy markedly increases his vulnerability for substance abuse
Conduct disorder
This psychiatric disorder is characterized by chronic low level depression with a bout of major depression
Double depression
Initiation of pharmacotherapy with an SSRI in a pt with Bipolar disorder I is likely to result in this condition
Manic episode
be careful when starting antidepressants
Pt can look laterally, but eyes cannot look medially w/o convergence
MLF lesion
(ie: left MLF lesion if left eye cannot follow medially)
- III nerve is in tact, communication btwn VI nerve complex is not in tact
Lesion location with several weeks of numbness in the absence of pain on butt and under dorsal thighs
- loss of bowel, bladder, and sexual fxn over same period of time
conus medularis syndrome
cauda equina: pain is an early feature, bowel, bladder, sexual fxn is lost at a LATER point in time
ocular findings in a right fourth nerve palsy
when you look down and in: eyes go in and up. Pt will often times tilt their head away from side of the lesion.
(SO normally depresses the eye when it faces medially and intorts the eyes when it faces laterally)
Blocker of opioid receptor in the nucleus accumbens, in combo with psychotherapy has modest success in the tx of alcoholism
naltrexone
orally and shot in the butt every month
this general anesthetic is associated with higher incidence of malignant hyperthermia that can be managed with this blocker of a ryanodine sensitive calcium channel
Halothane
tx with dantrolene
route of administration of most rapid onset of CNS action
inhalation
pathogenesis and four most locations for spontaneous hypertensive intracerebral hemorrhage
PONS
Cerebellum
Caudate
Lenticulate striate vessels (small ones that come off of large ones) that are affected
Chronic HTN: deposition of collagen in the vessels, weakening the walls (charcot buchard aneurysms)
position of eye in primary gaze, and other findings in a case of a complete third nerve palsy
ptosis
dilated pupil (mydriasis)
opthalmoparesis
down and out
Appendymoma
4th ventricle
pediatric/young adult
rosettes
(FYI: homer rosette: medulloblastoma)
CN affected in pt with R tongue deviation
where do we find nucleus
umn or lmn lesion?
R hypoglossal n. lesion
nucleus is right in the mid line
LMN lesion (not a cortico contralateral lesion bc of atrophy + fasciculation )
action of typical anti-psychotic agents on this brain pathway is responsible for their side effect of hyperprolactinemia
tuberoinfundibular pathway
not mesolimbic, mesocortical, nigrostriatal
most common type of anxiety disorder with prevalence of 13.5%
social anxiety
afferent pupillary defect
swinging flashlight test
affected eye will dilate (less light is being recieved by affected eye)
afffected nerve root and the forament through which it exits the spinal canal, in the case of a pt with radiculopathy causing numbness over the anterior and medial leg, weakness of quads, and diminished patellar reflex on affected side
L4 nerve root
exits spinal canal btwn L3,L4?
You would perform these tests to evaluate the fxnal pathways associated with 5th CN
Corneal blink reflex (V1)
Jaw jerk reflex / m. of mastication
Pain + temp + vibration sensation
(not really proprioception)
anencephaly: failure of this event occuring
failure of closing of rostral neuropore during 3rd week when neural tube closes
LMN lesion
flaccid paresis (not spastic) fasciculation muscle weakness atrophy hypotonia hyporeflexia
drug of abuse eliminated by zero order kinetics
ethanol
likely dx of a pt who presents with progressive weakness in all 4 extremities over months, with diffuse hyperreflexia, atrophy, and fasciculations
ALS
upper and LMN lesion
