why does ammonia cause encephalopathy?
it causes an increase in GABA inhibitory transmission
precipitating factors for hepatic encephalopathy
GI bleed, hypovolemia, metabolic acidosis, hyperkalemia, hypoxia, sedative use, infection, hepatic vascular occlusion
how does lactulose work?
it acidifies colonic contents, which converts absorbable ammonia into ammonium, which is not-absorbable (creates an ionic trap)
what are treatment options for hepatic encephalopathy if lactulose doesn't work?
sodium benzoate, ornithine aspartate, reduce protein intake (don't stop it though!)

si/sx of atrial myxoma
looks like mitral stenosis without opening snap, exertional dyspnea, fatigue weight loss
drug of choice for increasing HDL
fibrates, not nicotinic acid because of side effects

tumors most often assoc with tumor lysis syndrome
Burkitt's, the leukemias
what do you do if you suspect SBP?
diagnostic pericentesis
bacterial species assoc with struvite stones
