Pediatric Appendicitis: Association of Chief Complaint With Missed Appendicitis.

Objectives: We evaluated the association between the emergency department (ED) triage chief complaint and rate of missed appendicitis in children.

Methods: We performed a retrospective chart review of patients who presented to a pediatric ED and were diagnosed with appendicitis over 5 years (July 1, 2009 to June 30, 2014). We reviewed the medical record for any additional ED visits in the 7 days preceding the diagnosis of appendicitis.

Identification of Pediatric Patients With Celiac Disease Based on Serology and a Classification and Regression Tree Analysis.

Background & Aims: Celiac disease is detected using serology and endoscopy analyses. We used multiple statistical analyses of a geographically isolated population in the United States to determine whether a single serum screening can identify individuals with celiac disease.

Methods: We performed a retrospective study of 3555 pediatric patients (18 years old or younger) in the intermountain West region of the United States from January 1, 2008, through September 30, 2013.
