Community-Acquired Pneumonia Diagnosis Following Emergency Department Visits for Respiratory Illness.

Community-acquired pneumonia (CAP) is often considered for children presenting to the emergency department (ED) with respiratory symptoms. It is unclear how often children are diagnosed with CAP following an ED visit for respiratory illness. We performed a retrospective case-control study to evaluate 7-day CAP diagnosis among children 3 months to 18 years discharged from the ED with respiratory illness from 2011 to 2021 and who receive care at 4 hospital-affiliated primary care clinics.

Diagnosis and Management of Pneumonia in Infants Less Than 90 Days of Age.

Background: Current guidelines and recent studies on pediatric pneumonia pertain to children older than 3 months of age. Little information exists regarding the diagnostic evaluation, management, and outcomes of infants less than 90 days with pneumonia.

Methods: We compared infants <90 days of age diagnosed with pneumonia across 38 US children's hospitals from 2016 to 2021 to children 90 days to 5 years of age.

Autoantibody cluster analysis in juvenile lupus nephritis.

Objective: Demographics, clinical features, and biomarkers do not consistently anticipate risk of end-stage renal disease (ESRD) in juvenile lupus nephritis (LN). Here, the existence of autoantibody clusters predictive of ESRD was explored in a cohort of biopsy-proven juvenile LN.

Methods: A retrospective chart review was performed of patients with juvenile systemic lupus erythematosus (jSLE) and biopsy-confirmed LN.
