That is true. And after realizing it'll be a topic for residents/attendings ala a grand rounds topic, that makes much more sense. I was thinking more like a student presentation for students with an attending or two critiquing.
I remember as a student having to present at grand rounds, and was thinking it would be horrible. After all, they are smart doctors and I'm a dumb little nitwit. But, looking at the literature isn't as scary as it sounds. Especially if you look at journal articles, it'd be a great help. In my case though, I did stick with a basic topic but used like one or two interesting tidbits 😛
The best of both worlds would be to do a quick presentation on an interesting case, and present a topic based on the case that would draw interest. With southernIM's suggestion, if there was an interesting rectal CA case, a quick presentation with a topic on new therapies for it could cover a lot of bases.
