Flashcards in 5/15 Deck (55)
1

Test for acromegaly after IGF-1

GH measurement after oral glucose load (if pos will se paradoxical increase in GH levels)

2

Further eval of unstable pt's after BAT w/ negative DPL should look for what

Possible pelvic fracture w/ retroperitoneal hemorrhage

3

When does selective survival bias occur

In case control studies when cases are selected from the entire disease population instead of just those that are newly diagnosed

4

3 agents that shift K intracellularly

1. Insulin and glucose
2. Sodium bicarb
3. Beta-2 agonists

5

MC pediatric tumor

Benign astrocytomas (for both infra and supratentorial)

6

Development of AV blok in a patient with infective endocarditis should raise suspicion for what

Pervivalvular abscess extending into the adjacent cardiac conduction tissues

7

Typical presenting symptom of a choleseatoma

New onset hearing loss or chronic ear drainage despite therapy

8

Otoscope of cholesteatoma

Granulation tissue and skin debris within retraction pockets of TM

9

DiGeorge CATCH

Conotruncal cardiac defects
Abnormal facies
Thyimic aplasia
Cleft Palate
Hypocalcemia

10

Two tests for when Digeorge is suspected

Serum calcium levels and echocardiography

11

Complication of Mono

Autoimmune hemolytic anemia and thrombocytopenia due to cross reactivity of EBV induced Ab against RBCs and platelets

12

Legionella PNA tx

Quinolone or macrolide

13

Murmur heard after aortic dissection

Aortic regurg - early diastolic crescendo/decrescendo

14

C. diff risk drugs besides Ab

PPIs and H2 blockers

15

Anti HbE seen in what phase of Hep B

Recovery phase

16

Extra pulmonary sarcoid big 3

Arthritis
Uveitis
Erythema Nodosum

17

What is elevated in alcoholic hepatitis besides AST/ALT

GGT and ferritin (ferritin is an acute phase reactant)

18

Benign murmur features

Grade I or II, early or mid systolic, and decreases with standing

19

Suspect what in a young female w/ bilateral TN

MS

20

Anticoagulation good for pt's w/ renal dz

Unfractionated heparin (reduced renal clearances makes direct Xa inhibitors stronger) then warfarin

21

Dendritic ulcer in eye

Herpex simplex keratitis

22

Why no try to convert breech presentation prior to 37 weeks

Majority self correct by then

23

Ovarian tumor that can produce estrogen

Granulosa cell tumors

24

What is Leriche syndrome

Arterial occlusion at the bifurcation of the aorta into the common iliac arteries
*impotence almost always present*

25

Best test for virilizing neoplasm? interpretation?

Serum testosterone and DHEAS levels
Inc T w/ normal -----DHEAS indicate ovarian source
-Inc. DHEAS w/ normal T indicates adrenal source

26

4 big complications in DES daughters

1. Clear cell adenocarcinoma of vagina and cervix
2. Structural anomalies of repro tract
3. Pregnancy problems
4. Infertility

27

Why is right sided ovarian torsion more common than left

Longer length or uretero-ovarian ligament and left rectosigmoid colon occupies the space around the left ovary

28

What should be suspected in pt's who have combo of hemolytic anemia, cytopenias, and hyper coagulable state

Paroxysmal nocturnal hemoglobinuria

29

2 GI complications of HSP

GI hemorrhage or intussusception (small bowel or ileo-ileo)

30

Adult women w/ rubella get what

Arthritis than can last up to a month after resolution of other symptoms

31

Why steatorrhea in ZE syndrome

Inactivation of pancreatic enzymes

32

SAIDH tx

Fluid restriction ( hypertonic saline for severe symptomatic or resistant hyponatremia)

33

Acid base status in Fe overdose

Anion gap metabolic acidosis

34

WAS gene defect

X-linked recessive WAS (impaired cytoskeleton changes in leukocytes and platelets)

35

Hallmark brain damage of prolonged seizures

Cortical laminar necrosis

36

MCC when brain abscess results from sinusits

S viridians

37

3 causes of ARDs

1. Impaired gas exchange
2. Decreased lung compliance (stiff lungs)
3. Increased pulmonary arterial pressure (pulmonary HTN)

38

All pt's w/ hx of rheumatic fever should be on what

Penicillin ppx until 21 years old

39

40

What causes cirrhotic ascites

Increased hydrostatic pressure within hepatic capillary beds

41

Depressed phase of bipolar drug

2nd gen antipsychotics

42

Why oligohydramnios in late term

Aging placenta may have decreased fetal perfusion, resulting in decreased renal perfusion and decreased urinary output from the fetus

43
