I did. I couldn't recall anything that was handled that got a Derm out of bed. I was trying to think of something that only a Derm would handle - there has to be something- and was coming up blank. I was waiting for you to refresh me.
I got called for things like Stevens-Johnson syndrome, toxic epidermal necrolysis, some incredibly severe allergic reactions to all sorts of things but honestly, most of the midnight calls from the ER were for me to come see a patient and insure the doctors and nurses that what they were looking at was not contagious (that is was a allergic drug rash instead of scabies for example) as they were just afraid to catch something. Having trained as both an internist and a psychiatrist first, often times the emergency was something i had the advantage of an overall perspective. As the years went by, I spent most of my career as a skin cancer reconstructive surgeon and although most of the conditions I dealt with were serious, there really was virtually no emergent nature to any of them. A delay of a few hours certainly did not make a difference in the overall mortality or morbidity.
Honestly miss those years greatly but fully understand that the practice of medicine has now changed so much that much of the decision making would be removed from me and replaced by the insurance companies and the government.
