Detection of viruses in young children with fever without an apparent source.

Objective: Fever without an apparent source is common in young children. Currently in the United States, serious bacterial infection is unusual. Our objective was to determine specific viruses that might be responsible.

Evaluation of the precision of emergency department diagnoses in young children with fever.

OBJECTIVE. To characterize causes of fever in children presenting to a pediatric emergency department (ED). METHODS.

The presentation of appendicitis in preadolescent children.

Purpose: We describe the clinical presentation of appendicitis in preadolescent children and differences in symptoms among age-stratified subgroups.

Methods: This is a retrospective analysis of a prospectively collected de-identified data set of patients 3 years or older and patients younger than 12 years presenting to a pediatric emergency department during a 21-month period with symptoms suspicious for appendicitis. The rates of appendicitis, perforation, negative appendectomy, as well as sensitivities, specificities, and positive likelihood ratios for historical and clinical variables associated with appendicitis were calculated for the entire cohort and for 3 age-stratified subgroups.
