Quick Review: Septic Arthritis

00:01 Alright so let's do a quick quiz to try and highlight some of the information we've discussed.

00:05 What I'm gonna do is present four very tight little vignettes and see if you can come up with a diagnosis just from these limited information.

00:12 First one.

00:13 Headache, fever, recent camping trip and that rash.

00:21 Okay, hopefully you recognized that rash as erythema chronicum migrans.

00:26 This is a classic picture for Acute Lyme.

00:29 Moving on to the second case: A 29 year-old woman who's experiencing migratory polyarthralgias and you see some vesicles and pustules on her palms.

00:42 Great, this is a classic illness script for gonococcal infection, so called Disseminated Gonococcal Infection.

00:49 Okay, let's move on to the third one: A 25 year-old man with a recent diarrheal illness and what looks like either conjunctivitis or potentially even scleritis.

01:02 Okay, that kind of constellation of antecedent diarrheal illness or antecedent genitourinary infection, along with scleritis and presumably some joint disease, should make you think about Reactive Arthritis And the last case: An obese older man with a history of CKD shows you this painful thumb.

01:27 Okay, so that is a classic picture of Chronic Tophaceous Gout.

01:32 Those tophi in the DIP are essentially pure uric acid crystals with some inflammatory debris as well.

01:40 This is somebody who clearly has chronic gout.

01:43 And I think that's all for today.
