Commotio cordis is caused by the blunt impact of a hard object directly over the heart occurring during a specific window of ventricular repolarization leading to immediate collapse, ventricular fibrillation, and cardiac arrest. This episode focuses on risk factors and management of this rare but catastrophic injury.

Mycoplasma pneumoniae – PEM Currents: The Pediatric Emergency Medicine Podcast

In this episode we dive into the resurgence of Mycoplasma pneumoniae—an atypical bacterial cause of community-acquired pneumonia that’s making waves in pediatric emergency medicine. We’ll cover its clinical presentation, epidemiology, diagnostic approach, and management, including why standard beta-lactam antibiotics won’t work. Plus, we’ll discuss whether M. pneumoniae even needs to be treated in the first place! Learning Objectives […]
