When to suspect HIT

When platelet counts fall > 50% from baseline 5-4 days after starting heparin

10

Gold standard to dx HIT

Serotonin release assay

11

Why a high level of false negatives in serologic testing for primary syphillis

Many patients have yet to form antibodies

12

Odd place cholecystitis hurts

Right shoulder

13

What is osteomalacia due to? What does it lead to

Due to defective mineralization of the organic bone matrix MC due to severe bit D def, leading to decreased intestinal Ca and PO4 absortion with resultant secondary Hyper-PTH

14
