Epidemiological Characteristics of Pathogens in Bronchoalveolar Lavage Fluid in Children With Lower Respiratory Tract Infections: A Retrospective Analysis.

Background: The COVID-19 pandemic has significantly altered the etiological spectrum and epidemiological characteristics of pediatric respiratory diseases, and a profound understanding of these changes is crucial for guiding clinical treatment. The purpose of this study is to analyze the etiological patterns and epidemiological features of pathogens in bronchoalveolar lavage fluid (BALF) from children with pediatric lower respiratory tract infections (LRTIs) after the COVID-19 pandemic, with the aim of providing effective therapeutic evidence for clinical practice.

Methods: This study enrolled pediatric patients diagnosed with LRTIs who were treated and underwent BALF pathogen detection at our hospital from June 1, 2023, to June 1, 2024.

Early predictors of delayed radiographic resolution of lobar pneumonia caused by Mycoplasma pneumoniae in children: a retrospective study in China.

Background: Lobar pneumonia caused by Mycoplasma pneumoniae is a relatively difficult-to-treat pneumonia in children. The time of radiographic resolution after treatment is variable, a long recovery time can result in several negative effects, and it has attracted our attention. Therefore, exploring factors associated with delayed radiographic resolution will help to identify these children at an early stage and prepare for early intervention.
