Endoscopy in Infants With Gastrointestinal Bleeding Has Limited Diagnostic or Therapeutic Benefit.

Objectives: Pediatric gastroenterologists are often consulted to perform diagnostic and therapeutic endoscopy in infants with gastrointestinal bleeding (GIB). The value of endoscopy and risk of complications in this population are not well characterized. We aimed to describe findings and outcomes of infants with GIB who undergo endoscopy.

Exercise heart rates in patients with hypertrophic cardiomyopathy.

The exercise heart rate (HR) profile and its relation to cardiac function and arrhythmias were investigated in patients with hypertrophic cardiomyopathy (HC). Chronotropic response (CR) and heart rate recovery (HRR) were computed during and after treadmill exercise testing in 273 patients with HC and 95 age-matched healthy controls. Patients with HC had higher prevalence of chronotropic incompetence and lower HRR1-5min compared with controls.
