@OhioStateIMRes I'm back on Twitter for a bit to get some intel for tomorrow's lecture on aggressive lymphomas - let me know what you want to learn about!
#askrenal elderly lady admitted with Na 120 (135 3 days ago). Chronically poor po intake with nausea/vomiting, diarrhea 4 times daily. Sosm 243, Uosm 397, spec grav 1.013, UNa 45, SCr 0.72. Seems like straightforward hypovolemic hyponatremia, but why high UNa? No diuretics...
@GharibSary Seems like more of the latter today... N some response but minimal (124), uosm remains high. TSH and cortisol normal. Looking more like SIADH
