Morphofunctional changes following adenotonsillectomy of obstructive sleep apnea children: a case series analysis.

Objective: To perform a case series analysis of the changes in the pulmonary artery systolic pressure (PASP), nasal inspiratory flow (NIF), upper airway volume, obstructive apnea/hypopnea index (OAHI), and the maxillomandibular three-dimensional (3D) morphology after adenotonsillectomy (T&A) of obstructive sleep apnea children (OSA).

Materials And Methods: Retrospective assessment of files from 1002 children screened between 2012 and 2020 in a hospital-based mouth-breather referral center. From this universe, 15 obstructive sleep apnea children (7 females; 8 males), ages 4.

Pulmonary hypertension evaluation by Doppler echocardiogram in children and adolescents with mouth breathing syndrome.

Introduction: Adenotonsillar hyperplasia (ATH) and allergic rhinitis (AR) are the most common causes of upper airway obstruction in children. Such diseases, by affecting the upper airways, can cause chronic alveolar hypoventilation, pulmonary vasoconstriction and pulmonary hypertension, which in some cases, are irreversible.

Objective: This cross-sectional study aimed to evaluate the prevalence of pulmonary hypertension in two groups of mouth-breathing (MB) 2-12 years old children with ATH and isolated allergic rhinitis, through Doppler echocardiography.

Impact of an asthma management program on hospitalizations and emergency department visits.

Objectives: To assess the frequency of hospitalizations and emergency department visits of children and adolescents before and after the enrollment in an asthma program.

Methods: Medical records of 608 asthmatics younger than 15 years were assessed retrospectively. The frequency of hospitalizations and emergency department visits caused by exacerbations were evaluated before and after enrollment in an asthma program.
