We had another exemplary installment of Grand Rounds this week that started with Attending Case Followup with Drs. Lang, Baez, and Paulsen. Then we had some top-notch review of core curriculum with Dr. Winslow and the Alvarado Score for appendicitis, Drs. Meigh and Klaszky on food impactions and esophageal foreign bodies, and Drs. Comiskey and Nagle on D-dimer. Finally, Dr. Nagle gave us an overview of the foundations of evidence-based medicine with his R4 capstone.
