Flashcards in Shit - Derm/Rheum UWorld Deck (14):
1

LEMS vs MG

LEMS has proximal weakness (stairs and up form chairs), hypo or a-relfexia, autonomics (dry mouth, impotence).

Both can have ocular involvement (diplopia)

2

flattened deltoid: nerve, injury, sensory and motor loss

Axillary (C5-C6)
Anterior dislocation of humerus (and and ext. rotated i.e. throwing a ball)
Sensory = lat. arm
Motor = deltoid and teres minor

3

Painful red joint with WBCs; cell count differential

20 000 = gonococcal arthritis

4

Causes of gout

Thiazides, fatty meals, alcohol, Leish-Nyhan, PRPP excess, cell turnover, von Gierke disease

5

Causes of pseudogout

hemochromatosis, hyperparathyroidism, OA

6

Gout vs pseudogout

gout = monosodium urate.
pseudogout = calcium pyrophosphate

7

Terbinafine use and mechanism

dermatophytes, especially onychomycosis; block squalene epoxidase

8

Lower trunk of brachial plexus injury: name, nerves, s/s

Klumpe's palsy.
C8 + T1 .: median and ulnar
All intrinsic hand muscles, total claw hand, sensory of medial forearm

9

how to injure radial nerve:

midshaft humerus fracture, crutches, armpit chair

10

increase supraspinatus pain with what arm movement

abduction

11

caudal regression syndrome

via poorly controlled maternal diabetes. Genesis of sacral and lumbar spine, flaccid leg paralysis, dorsiflexed feet, urinary incontinents

12

pre-patellar brusitis via

kneeling

13

male-pattern baldness (androgenic alopecia) inheritence

polygenic with variable penetrance, with androgen-R on the X-chromosome

14

isotrenitoin =

acutane: interacts with RAR so teratogenic
