Kids scare me

Sick kids, that is. I did my medical school pediatrics rotation in 1992, and have almost exclusively treated adults since then. I had to see a young kid in the ER this weekend, and for reasons that are somewhat complex, I am the "most responsible physician" - I avoid that status in general, let along when I am dealing with someone outside my usual patient group. I am worried; this kid is sick, but has the potential to get much sicker. It's funny how some patients get under your skin, while others make little impression on you.
