Aerobic exercise and snoring in overweight children: a randomized controlled trial.

Objective: To determine whether regular aerobic exercise improves symptoms of sleep-disordered breathing in overweight children, as has been shown in adults.

Research Methods And Procedures: Healthy but overweight (BMI > or =85th percentile) 7- to 11-year-old children were recruited from public schools for a randomized controlled trial of exercise effects on diabetes risk. One hundred children (53% black, 41% male) were randomly assigned to a control group (n = 27), a low-dose exercise group (n = 36), or a high-dose exercise group (n = 37).

Acute onset of Wegener's granulomatosis and diffuse alveolar hemorrhage treated successfully by extracorporeal membrane oxygenation.

Wegener's granulomatosis is a necrotizing granulomatous vasculitis involving the upper airway, lungs, and kidneys. Diffuse alveolar hemorrhage is a rare and life-threatening presentation of Wegener's granulomatosis. We report on a previously healthy 13-yr-old boy who presented with fulminant pulmonary hemorrhage leading to acute respiratory distress syndrome and was found to have Wegener's granulomatosis.
