Bronchodilator response to albuterol nebulized with hypertonic saline in asthmatic children.

Introduction: Asthma is distinguished by bronchial obstruction reversible by bronchodilators. The first-line treatment for asthmatic exacerbations is the use of inhaled beta-agonists, by pressurized metered-dose inhalers or nebulized with normal saline solution (NSS). There are no reports of nebulized beta agonists' efficacy in asthmatic children when administered with hypertonic saline solution (HSS).

Pediatric multisystem SARS COV2 with versus without cardiac involvement: a multicenter study from Latin America.

Latin America (LATAM) children offer special insight into Severe Acute Respiratory Syndrome Coronavirus 2 (SARS COV2) due to high-risk race/ethnicity, variability in medical resources, diverse socioeconomic background, and numerous involved organ systems. This multinational study of LATAM youth examined the distinguishing features of acute or late multisystem SARS COV2 with versus without cardiac involvement. A consecutive sample of youth 0-18 years old (N = 98;50% male) presenting with multisystem SARS COV2 to 32 centers in 10 Latin American countries participating in a pediatric cardiac multi-imaging society were grouped as with versus without cardiac involvement, defined as abnormal echocardiographic findings or arrhythmia.

Risk factors associated with pulmonary exacerbations in pediatric patients with cystic fibrosis.

Introduction: Cystic fibrosis patients develop pulmonary exacerbations (PEs) that require intravenous treatment. The objective of this study was to determine the risk factors associated with PEs and establish the percentage of patients who failed to recover their lung function.

Population And Methods: Observational, retrospective, cohort study.
