Eosinophilic Esophagitis in the Setting of Prior Caustic Ingestion.

A seven-year-old male presented with complaints of food refusal, dysphagia, and odynophagia for three weeks. He also had a history of caustic ingestion six months prior to the presentation. Diagnostic esophagogastroduodenoscopy (EGD) revealed post-burn esophageal stricture, and biopsy confirmed eosinophilic esophagitis (EoE).

Improving performance on night shift: a study of resident sleep strategies.

Study Objectives: To identify sleep strategies of internal medicine residents transitioning to night shift and report their effect on performance.

Methods: Residents logged hours of sleep and work starting 3 days prior to the first night shift and continuing through the next 8 days. Cohorts were defined by sleep logs and compared separately by transition strategy, total hours of sleep, amount of sleep occurring at work, weekend sleep schedule, and residency training year.

Septic arthritis of the hip and knee treated surgically in pediatric patients: Analysis of the Kids' Inpatient Database.

Sonic Hedgehog Signaling Regulates Myofibroblast Function during Alveolar Septum Formation in Murine Postnatal Lung.

Sonic Hedgehog (Shh) signaling regulates mesenchymal proliferation and differentiation during embryonic lung development. In the adult lung, Shh signaling maintains mesenchymal quiescence and is dysregulated in diseases such as idiopathic pulmonary fibrosis and chronic obstructive pulmonary disease. Our previous data implicated a role for Shh in postnatal lung development.
