Standings as the sun rises on day #2

As we head into Day 2 of the Pediatric Emergency Medicine Twitter Trivia Contest we have a tight race at the top. Remember, that even though only the first person to answer gets the point - I'll do my best to respond to every post and give feedback on the answer. My primary aim is that you learn stuff. Basically, on day 1 I was impressed by your collective smarts!
