The following case was presented at the Eastern Allergy Conference May 2005 to each of four small group sessions in an attempt to incorporate problem-based learning (PBL) into the curriculum of the conference for the first time in its 18-year history. Before this, the format had always been non-stop lectures for four days. The attempt to use PBL in breakout sessions was due to the well-documented improved learning experience with PBL demonstrated by multiple studies in the literature of PBL for CME. This PBL case on an adult who presents with a "chronic cough" was linked to a series of three didactic lectures to reinforce the differential diagnoses in this patient. The three lectures followed the PBL breakout sessions (during the morning of the conference) and were entitled Laryngeal Pharyngeal Reflux (LPR), Chronic Sinusitis: A Surgical Perspective and Chronic Cough. Although the best learning scenario for this case occurs when there is interaction with one's peers, review of this case and answering the questions that were posed by the facilitators can still provide a great learning experience.
