Bronchiolitis 2021-2022 epidemic: multicentric analysis of the characteristics and treatment approach in 214 children from different areas in Italy.

Bronchiolitis causes a remarkable number of hospitalizations; its epidemiology follows that of respiratory syncytial virus (RSV), its main pathogen. The aim of this study was to evaluate the presenting features, treatment approach, and impact of medical therapy in four pediatric hospitals in Italy. Data on infants < 24 months of age hospitalized with bronchiolitis in the 2021-2022 season were collected.

New Insights on Early Patterns of Respiratory Disease among Extremely Low Gestational Age Newborns.

Background: The analysis of early patterns of lung disease among preterm infants may help to identify predictors of pulmonary deterioration.

Objectives: To analyze FIO2 requirement in the first 14 days of life among preterm infants and to find predictors of bronchopulmonary dysplasia (BPD).

Methods: Retrospective cohort study.
