What is the causal agent of seborrheic dermatitis? What are 2 associations?
Pityrosporum ovale; HIV (screen) and Parkinson dz
What is the most common cause of febrile neutropenia?

What 2 markers are fairly specific for Hairy Cell Leukemia?

What is the cause of angina whether due to anemia, AS, or angina?
Mismatch of O2 supply and demand
What is Hungry Bone Syndrome?
Occurs when a pt with primary hyperparathyroidism with preoperative bone dz gets parathyroidectomy; the bones then suck up all the Ca and there is no PTH to increase it so they get a symptomatic HYPOcalcemia
What is the way to localize the bad parathyroid gland prior to parathyroidectomy for primary hyperparathyroidism?
Sestamibi scan

TMP-SMX; if spreads to brain add carbapenems
What is the use of a 24 hour free urinary cortisol to diagnose adrenal insufficiency?
USELESS, though the cortisol may be low it is not used for this. You use this when looking for cushings (hypercortisolism) as an initial screening test
Why would laying a pt with R lower lobe PNA on his right side cause a drop on SaO2?
More flow goes to the lung in the dependent position but if there is consolidation it wont get oxygenated so this can lead to drops in O2 sat
What should you think if a young person with nephrotic syndrome had crushing substernal chest pain?
MI; Nephrotic syndrome causes accelerated atherosclerosis because it causes the liver to overproduce lipids, it also overproduces fibrinogen leading to hypercoagulability
What should you suspect in a pt with DOE and achalasia-like sx?
