This week I hope to debunk one of rheumatology's "paradoxes." We love to talk about these and subject our fellows to memorizing them for the boards. We often use them to guide clinical practice, but I suspect that many "paradoxes" are actually the result of shoddy epidemiology. Todays' paper from JAMA dermatology covers one that I have heard frequently, which is that steroids cause psoriasis flares. I hope you enjoy!
