Gastrointestinal involvement in IgA vasculitis: a single-center 11-year study on a cohort of 118 children.

Introduction And Objectives: Immunoglobulin A vasculitis (IgAV), the most common childhood vasculitis, is associated with gastrointestinal (GI) involvement in 50-75% of cases. The aim of this study was to describe the characteristics of GI involvement in a cohort of hospitalized children with IgAV.

Methods: We retrospectively evaluated patients hospitalized for IgAV at Meyer Children's University Hospital, from January 2010 to December 2020.

Laryngeal microsurgery under general anesthesia using small-bore endotracheal tubes: blood gas analysis.

This study reports variations observed under general anesthesia through small-bore endotracheal tubes in PO2, PCO2, HCO3, percentage saturation of O2, and pH levels in 39 patients who underwent laryngeal microsurgery lasting from 10 to 100 minutes. The tendency to an increase in PCO2 levels reached statistical significance only at the 100th minute but did not constitute a risk for patients as values remained within the limits of "permitted hypercapnia." PO2, percentage saturation of oxygen, and HCO3 levels did not vary significantly.
