Congenital heart disease and heterotaxy: upper gastrointestinal fluoroscopy can be misleading and surgery in an asymptomatic patient is not beneficial.

Purpose: Heterotaxy syndrome is associated with intestinal abnormalities. We sought to define the gastrointestinal anatomy and determine both the risk of volvulus and benefit of screening upper gastrointestinal fluoroscopy (UGI) in these patients.

Methods: Medical records from 2003 until 2011 at Children's Hospital Los Angeles were reviewed in patients with heterotaxy for cardiovascular diagnosis, gastrointestinal symptoms, imaging and surgical arrangement of viscera, perioperative morbidities, and overall mortality.

Intraoperative hypercyanosis in a patient with pulmonary artery band: case report and review of the literature.

A case of intraoperative cyanosis in a patient with a common atrioventricular canal palliated with a pulmonary artery (PA) band is presented. The patient's physiology was consistent with cyanosis due to inadequate pulmonary blood flow, and responded quickly to typical interventions used for a hypercyanotic episode in a patient with unrepaired Tetralogy of Fallot. Differences and similarities in the physiology of PA banding compared with Tetralogy of Fallot are presented, including a rationale for treatment options for hemodynamic decompensation occurring in the setting of anesthesia and surgery.

Validation of nutrient intake using an FFQ and repeated 24 h recalls in black and white subjects of the Adventist Health Study-2 (AHS-2).

Objective: To validate a 204-item quantitative FFQ for measurement of nutrient intake in the Adventist Health Study-2 (AHS-2).

Design: Calibration study participants were randomly selected from the AHS-2 cohort by church, and then subject-within-church. Each participant provided two sets of three weighted 24 h dietary recalls and a 204-item FFQ.
