Dr. Andy Pollak, chief of orthopedics for the University of Maryland Medical System, led a team of doctors in Haiti immediately following the 2010 earthquake. Pollak has since made several trips there, most recently to train Haitian doctors in trauma care. He joins us, along with Kim Pozniak, a communications officer for the Baltimore-based Catholic Relief Services, who will talk about the ongoing uprisings and violence in the Central African Republic.
