This weeks Grand Rounds was started off with our guest lecturer, Dr. Esther Choo, who gave a compelling talk regarding gender disparities in medicine and the effects of gender bias in our profession and every day practice.  This was followed by Dr. Owens and Ventura giving their evidence based approach to the management of A-Fib, as well as previewing their upcoming algorithm for Tamingthesru.com.  Our pediatric EM colleague Dr. Valentino then walked us through current recommendations on the approach to the febrile infant.  In the last hour, Dr. Iparraguirre gave us a lecture on the approach to rashes in the ED.  The conference then concluded with an R4 clinical soap box lecture by Dr. Dang on the history of cannabis and medical marijuana, as well as the research behind its current use.
