Greatest risk factor for prematurity
EEG of complex partial seizures
Normal or brief discharges
What is pseudomotor cerebri
idiopathic intracranial hypertension
A/R disorder due to cystathionine synthase deficiency results in error in methionine metabolism
What are some of the pathognomoic feature/events in homocystinuria?
Intellectual disability and cerebrovascular accidents/thromobosis
Tx for homocytinuria
vit supplementation, antiplatelet or anticoagulation to prevent thromboembolic events
Loss of consciousness is seen with what kidn of partial seizures
Complex partial and partial seizure with secondary generalization
Infant botulism is caused by? Where can it come from?
Clostridium botulinum spores. Honey and also spores from environmental dust/soil.
What is the presentation of infant botulisnism?
Descending flaccid paralysis, autonomic symptoms like constipation, drooling, bulbar palsies (ptosis, sluggish pupillary responses, poor suck/gag reflex)
What is the treatment for infant botulism
Human derived botulism immune globin
Epidural hematoma clinical ppt
Lucid interval and then rapid deterioriation
CT appearance of epidural hematoma
Biconvex mass on CT scan
tx for epidural hematoma
If patients show deteriorating neurological status or increasing ICP = emergent craniotomy
Ascending polyneuropathy after recent GI infection?
Underlying pathology of guillan barree involves what ?
Peripheral motor nerves
Final stage of guillan barre?
Flaccid paralysis, absent deep tendon reflexes and nerve conduction abnormalities
What does CSF in guillan barre show?
Elevated protein levels and normal cell count
Illnesses that involve anterior horn cells?
spinal muscular atrophy (flaccid paralysis in infancy), poliomyelitis, and ALS
What is the best means of monitoring respiratory function in patients with Guillan barre
Serial measurements of forced vital capacity
What are important predisposing risk factors for brain abscesses
otitis media, mastoiditis, frontal or ethmoid sinusitis, dental infection, bacteremia from other sites of infection, congenital heart disease
Classic triad of brain abscesses
Fever, headaches (nocturnal or morning), focal neurological changes. Seizures present in 25% of cases.
What is polycythemia
Increased concentration of hemoglobin
Infantile spasms can develop into
West syndrome (infantile spasms, psychomotor developmental arrest, hyperarrythmia) or lennox gastuaut
Typical EEG for infantile spasms
Hypsarrythmia (high voltage slow waves, spikes and polyspikes, background disorganization)
Infantile spasm onset
Tx for infantile spasms
Vigabatrin, ACTH, benzodiazepines
1) multipe seizure types 2) diffuse cognitive dysfunction 3) slow generalized spike and slow wave EEG
Tx for lennox-gaustaut
Valproic acid, benzoes, ketogenic diet; however, response often poor
