Over the past 10 years, continuous positive airway pressure (CPAP) has revolutionized the prognosis and management of bronchiolitis patients hospitalized in pediatric intensive care units (PICUs). High-flow nasal cannula (HFNC) is emerging as an alternative to CPAP. Despite encouraging results of several clinical and physiological studies, HFNC use remains controversial and its indications heterogeneous. To better define the place of HFNC in severe bronchiolitis respiratory support, we investigated the different ventilation assistance techniques used for severe bronchiolitis over 3 days at the peak of a bronchiolitis epidemic in December 2015. We conducted an observational cross-sectional study in 27 French university hospital PICUs. Fifty-nine patients were included. The results show that HFNC already accounts for nearly half of the respiratory support techniques used for severe bronchiolitis in French PICUs with no significant difference between the CPAP group and the HFNC group of patients.

Background: Myanmar is one of the countries in Southeast Asia where serious dengue outbreaks occur and Yangon is among the regions with the highest number of cases in the country. Many infections including dengue are common in Yangon during the rainy season, and co-infections may also occur. Adults are more likely than children to experience co-infections of dengue and other diseases.

Objective: The management of a child presenting with a critical medical or surgical condition is a scarce event in the pediatric emergency department (PED). In this one year retrospective study, we have tried to better characterize the profile and care pathway of children who had been transferred to the neonatal or pediatric intensive care or critical care units (PICCU) after a visit to the PED, or died in PED.
Methods: Retrospective study of children who has been transferred to PICCU from the two PED of Marseille's University Hospital from the 1 of January 2022 until the 31 of December 2022.
Rationale: Airflow obstruction refractory to β2 adrenergic receptor (β2AR) agonists is an important clinical feature of infant respiratory syncytial virus (RSV) bronchiolitis, with limited treatment options. This resistance is often linked to poor drug delivery and potential viral infection of airway smooth muscle cells (ASMCs). Whether RSV inflammation causes β2AR desensitization in infant ASMCs is unknown.

Heterotaxy syndrome is characterized by abnormal left-right arrangement of thoracoabdominal organs and is frequently associated with complex cardiac anomalies. However, cases with predominant extracardiac manifestations are increasingly recognized. This report describes a 20-year-old female of North African descent with consanguineous parentage, who presented with chronic cough and exertional dyspnea persisting over several years.

Background: Bronchiolitis is the most common cause of lower respiratory tract infection (LRTI) in the first year of life. We analyzed the association between complete blood count (CBC), c-reactive protein (CRP), and novel inflammatory indexes (NLR, PLR, MLR, ELR, LMR, NPR, LPR, LNR, PNR, SII, SIRI) in predicting bronchiolitis severity at hospital admission.
Methods: We retrospectively collected data from 95 infants hospitalized for bronchiolitis in a third-level hospital during three epidemic seasons.
