Lesson of the month: Rowing-induced laryngeal obstruction: a novel cause of exertional dyspnoea: characterised by direct laryngoscopy.

Exercise-induced laryngeal obstruction (EILO) is a key differential diagnosis for unexplained dyspnoea in athletes. The gold standard means for diagnosis of EILO is direct laryngoscopy, performed continuously, while an athlete undertakes the specific sport that precipitates their symptoms. This report provides the first descriptions of rowing-associated EILO in two competitive rowers presenting with unexplained dyspnoea and cough. The report describes the methodology and safety of the use of continuous laryngoscopy in the context of maximal rowing ergometry and the use of this technique as a therapeutic tool to provide biofeedback.
