Pneumomediastinum After COVID-19.

A preadolescent female presented to the emergency department with an acute asthma exacerbation. Chest radiograph and computed tomography scan showed extensive pneumomediastinum with a small pneumopericardium without a distinct source for this air leak. The patient was admitted for noninvasive monitoring, analgesia, and high concentration oxygen.

Proximal Tubule Dysfunction Secondary to Salicylate Intoxication.

Aspirin overdose is still a common cause of presentation to the emergency department and is commonly seen in the setting of one-time, accidental or intentional ingestion of large amounts of salicylate-containing compounds, though can occur with long-term ingestion of super-therapeutic doses of medications. Salicylate toxicity has a predictable progression from early respiratory alkalosis to late metabolic acidosis. We present the case of a 14-year-old girl who intentionally ingested a handful of Aspirin and despite appropriate therapy, developed transient proximal tubule dysfunction.

Newborn With Vaginal Cyst.

A full-term newborn female was born with a 0.5 × 0.5 cm golden-colored fluid filled sac at the posterior aspect of the vaginal introitus.

Leg pain in an infant.

Nonaccidental trauma can be difficult to differentiate from osteogenesis imperfecta (OI), especially in the face of multiple fractures. When nonaccidental trauma is being considered, medical causes of injury must be ruled out. In this report, we discuss the case of an 11-month-old female infant who presented with a transverse femur fracture and was also found to have a healing transverse humeral fracture and rib fractures.
