UW mix 2 Flashcards
(271 cards)
Acute headache, nausea, blurry vision, sluggish and dilated pupil, and conjunctival injection
Acute angle closure glaucoma! Emergency, can cause permanent optic nerve damage in hours
Triggers for acute angle closure glaucoma?
Decongestants, antiemetics, anticholinergics (including trihexyphenyl used for the tremor in parkinson’s)
Parkinson’s treatments
Levodopa (DA precursor), pramipexole (DA agonist), and entacapone (increases DA stimulation), and selegiline (MAOI b)
7 year old girl, precocious puberty, ovarian mass -
Granulosa cell tumor - malignant, estrogen - secreting tumor.
Rule of 2’s
For Meckel’s diverticulum - 2% prevalence, 2% symptomatic at age 2, 2:1 male to female ratio, within 2 feet of the ileocecal valve
How to diagnose Meckel’s
Technicium 99 scan - with patient with painless hematochezia
Fancy names for disturbances in cerebellar lesions
Dysdiadochokinesia - difficulty w/ rapid alternating movements
Dysmetria - past-pointing on finger-to-nose testing
Limb ataxia
Intention tremor
Dextromethorphan - uses, mechanism, SEs
Cough suppressant, NMDA antagonist, can cause dissociation
Ptosis, down and out gaze, diplopia, and normal pupillary response? Cause? Common etiology? What if had no pupillary dilation to light?
Ischemic oculomotor (CNIII) nerve palsy, usually from diabetes causing ischemic neuropathy - If also pupillary response gone - involves inner and outer (parasympathetic) fibers of CNIII nerve - would be lacunar infarct
Poison Ivy - what type of hypersensitivity reaction?
Type IV (IVy!) - delayed, T-cell mediated response. Requires previous exposure. Like contact dermatitis.
Name 4 types of hypersensitivities?
Type I: immediate, IgE mediated
Type II: cytotoxic, IgG and IgM
Type III: immune complex deposition (PSGN, SLE)
Type IV: delayed, T cell mediated
DeQuervain tenosynovitis - classic population and findings
New mothers that hold babies with thumbs up. Pain at radial/dorsal base of thumb
Pure motor hemiparesis, sudden onset - most likely?
Lacunar stroke - no cortical signs (aphasia, agnosia, ataxia, etc). Maybe in BG or internal capsule
internal carotid artery problem like dissection - sx
maybe neck pain, thunderclap headache, sx of ischemic stroke (hemiparesis, facial droop, aphasia).
Can be from orofacial trauma)
When to not use amitriptyline?
Patients >65 due to anticholinergic effects; also pt with pre-existing cardiac disease due to conduction abnormalities exacerbated
Erythema nodosum - what to look for?
Could be idiopathic. BUT always check for systemic things - TB, sarcoid, strep, coccidiodomycosis, IBD and Behcet
Wallenberg syndrome - site of infarct; artery involved; symptoms
Infarct - lateral medullary infarct
Artery - occlusion of posterior inferior cerebellar or vertebral artery
Symptoms - loss of pain and temp ipsilateral face and contralateral body; ipsi bulbar weakness, vestibulocerebellar impairment (vertigo, nystagmus), and Horner’s syndrome.
Motor - normal
First versus second line in BPH
1: alpha 1 blockers (terazosin, tamsulosin) - rapid response, relax bladder neck and prostate smooth muscle
2: 5 alpha reductase inhibitors - take 6-12 mo to work, inhibit conversion of T to dihydroT, reduces prostate size
Hard signs of vascular trauma; what to do about it
Signs: observed pulsatile bleeding, expanding hematoma, or signs of distal ischemia (cold limb, no pulses)
Do: urgent exploration (dont’ wait for imaging)
Main substrates for gluconeogenesis
alanine, lactate - these get converted to pyruvate
also glutamine and glycerol-3-phosphate involved
Fatigue, constipation, nephrolithiasis — think of?
Hypercalcemia - suggestive of hyperparathyroidism. Can also have pseudogout with CPPD - calcium pyrophoshate crystals. Rhomboids, positively birefringent. On joint x ray can see chondrocalcinosis in joint spaces.
hypoplastic fingers and nails + cleft lip + concern for bleeding at birth
Fetal hydantoin syndrome. Pregnant women on phenytoin. In final trimester, get vitamin K to prevent neonatal bleeding, since phenytoin increases rate of fetal vit K degradation
morning vomiting, nocturnal headaches - concern for?
Intracranial pathology
poor feeding, irritability, head circumference %ile increasing, decreased activity, vomiting
Hydrocephalus - see tense and bulging fontanelle, prominent scalp veins, wide sutures
