One day in EMG clinic, we had a patient with wrist pain and intermittent wrist swelling. His workup for rheumatological disease was negative and his EMG only showed mild carpal tunnel.
Attending: "So do you think he has RS3PE?"
Me: [thinking: "Am I supposed to know what that is??"] "Uhhh...."
Attending: "That's Remitting Seronegative Symmetrical Synovitis with Pitting Edema."
Attending: [points to bulletin board, where article is pinned up] "We saw a really interesting case of it last week. I'll bet that's what he has. Was his sed rate elevated?"
Attending: "Maybe that's because he got prednisone."
Me: "It was normal before the prednisone."
Attending: "Well, it could still be RS3PE! We should put that diagnosis in our report!"
Me: [thinking] "Just because you have an article about something on the wall, that doesn't mean every patient has it."
I guess the diagnosis is possible. I love the fact that instead of calling it RSSSPE, they call it RS3PE.
