Flashcards in Set 5 Deck (58)
hypopigmented spots, axillary freckles, skin nodules, lisch nodules
NF 1 or 2
heart sound in MI
4th heart sound = atrial gallop (diastolic dysfxn and stiff LV)
IV atropine (muscarinic antagonist --> decreases vagal influence on SA node) then transcutaneous pacing
amylase in left-sided pleural effusion (3)
esophageal rupture, pancreatitis (or ruptured pseudocyst), or cancer
Tx prinzmetals angina
CCBs and/or nitrates
infant with central vs. peripheral cyanosis
central = hypoxemia in arteries suggesting CHD (ex perioral cyanosis but warm extremities)
peripheral = low cardiac output causing low blood flow/ excessive vasoconstriction --> normal PaO2, cold, cyanotic distal extremities
macrocytic anemia, leukopenia, thrombocytopenia and decreased segmentation of PMNs
Deficiency seen in carcinoid syndrome
Niacin (its precursor, tryptophan, gets all used up to make serotonin)
MRI shows butterfly appearance with central necrosis
MRI shows heterogenous, serpiginous contrast enhancement
high grade astrocytoma
SLE patient taking hydroxychloroquine, what test does she need to have?
eye exams q6mo looking for retinopathy and/or corneal damage
akathisia vs. dystonia vs. tics vs. myoclonus vs. chorea
- akathisia - restlessness
- dystonia - sustained muscle contraction - twisting, repetitive movements, or abn postures. focal or diffuse. ex. torticollis
- athetosis - slow, writhing movements. ex. huntington's. rett's syndrome.
- tics - repetitive movements or vocalizations. ex. tourette's
- myclonus - jerking movements
- chorea - brief, irreg, flowing movements
What is a sestamibi scan for?
direct treatment in patients with hyperPTH either sx or asx with Ca>11, GFR<60 +/- osteoporosis
Esophageal tests algorithim for ordering if broad ddx
Barium esophagram then EGD then esophageal motility
Esophageal varices vs Mallory-Weiss Tears?
varices = VEINS (2/2 portal HTN)
MWT = ARTERIES (2/2 mucosal tears from heaving)
HIV drug causing hypersensitivity syndrome
Eggshell calcification of hepatic cyst? Tx?
hydatid cyst = Echinococcus (via dog exposure)
Tx = Careful surgical drainage w/ albendazole
At what cutoff is it ok to give bicarb for metabolic acidosis?
pH <7.2, ie severe
Proximal muscle weakness + elevated CK? Tx?
Tx HIGH dose steroids (vs PMR)
CI of triptans (3)
uncontrolled HTN, CAD, Pregnancy
HIV drug causing hematuria w/ crystal-induced nephropathy
Indinavir (Protease Inhibitor)
Calcium levels in alkalosis, why?
decreased due to higher affinity of albumin for calcium
abnormality in coagulation profile in lupus
prolonged PTT 2/2 anticardiolipin Ab
Lip telangiectasias, epistaxis and polycythemia with normal WBC and plts
Hereditary telangiectasia aka Osler-Weber-Rendu
= AVMs occur primarily in mucus membranes, skin and GI tract but also liver, lung and brain
Liver mass histology with atypically enlarged hepatocytes containing glycogen and lipid deposits
heberden nodes and bouchard nodes
OA = osteophyte formation in DIP and PIP respectively
Tx cerebral hemorrhage while on warfarin
d/c warfarin, ASA and other anticoagulants
