2

Tricuspid valve atresia presentation/findings

-cyanotic heart disease w/hypoplastic R ventricle
-EKG: left axis deviation, peaked p waves
-CXR: decreased pulmonary markings

3

Total anamolous pulmonary venous return presentation/findinsgs

-all 4 pulm. veins fail to connect to L. atrium
-R atrial enlargement
-ECG: R ventricular hypertrophy, R axis deviation
-CXR: increased pulm. markings

4

Management of hyperCa

-severe ==> IV hydration + calcitonin, avoid loop diuretics if possible; long term = bisphosphonates
-moderate/mild ==> avoid thiazides/Li/volume depletion

5

Dx of HIT

-serotonin release assay
-start tx before confirmatory tests (stop hep & start thrombin inhibitor)

6

Tx of frostbite

-rapid re-warming with warm water
-do not debride immediately; re-eval after re-warming

7

HIV-assoc. kidney disease

FSGS

8

Tx in PAD

-PAD = type of ASCVD ==>
-ASA + statin

9

CMV colitis ==> ?

bloody diarrhea @ HIV pt. w/CD4

10

Evaluation of diarrhea @ HIV patient

1. stool test for ova/parasites
