Drs. Winslow and Habib started the Grand Rounds off with a case-based discussion on the Centor Criteria and testing for strep pharyngitis. Drs. Walsh and Sabedra led an interesting discussion about a case of TTP. In his R4 Case Follow Up lecture, Dr. Nagle presented about DKA and family presence during resuscitation. Dr. Hogan, one of the EMS Fellows, gave a great presentation about the current controversies in cardiac arrest management. Finally, the week wrapped up with some great simulation and cases from our PEM fellows about post T&A bleeds, PTA, and acute chest syndrome.
