Adenovirus Infection and Rhabdomyolysis as a Cause of Acute Liver Failure in a Healthy Collegiate Football Athlete: A Case Report and Proposed Return to Play Protocol for Rhabdomyolysis.

Adenovirus is a common cause of upper respiratory and gastrointestinal tract infections. Though cases of significant organ failure and death have been reported in young children and immunocompromised individuals, adenovirus infections in healthy individuals are typically self-limiting without significant morbidity or mortality. Exertional rhabdomyolysis is a pathologic condition resulting from repetitive, excessive, or prolonged exercise, often in a hot environment, leading to acute muscle injury, renal injury and, rarely, death.

Detection of concussion using cranial accelerometry.

Objective: To determine whether skull motion produced by pulsatile cerebral blood flow, as measured by cranial accelerometry, is altered during concussion.

Design: In phase 1, to identify a specific pattern indicative of concussion, cranial accelerometry of subjects who sustained a concussion underwent analysis of waveforms, which was compared with accelerometry from subjects without a concussion (baseline). In phase 2, this concussion pattern was tested against prospectively acquired, blinded data.

The ethics of health care reform: impact on emergency medicine.

The recent enactment of the Patient Protection and Affordable Care Act (ACA) of 2010, and the ongoing debate over reform of the U.S. health care system, raise numerous important ethical issues.
