Twenty-one cases of nasal airway obstruction were analyzed using computed tomography (CT) at the Children's Hospital in Boston between 1980 and 1984. Seven of these patients had stenosis of the entire nasal passage, two had stenosis of the anterior nasal cavity, and 12 had atresia of the posterior choanae. The spectrum of these abnormalities and the optimum technique for CT scanning are discussed.

Objective: High-flow nasal cannula (HFNC) is generally considered to have fewer enteral feeding problems than nasal continuous positive airway pressure (NCPAP) or nasal intermittent positive-pressure ventilation (NIPPV). However, the effects of HFNC on the feeding outcomes in preterm infants are still controversial. The aim of this study was to assess the effect of HFNC on postnatal growth and feeding.

Background: Determining why some upper respiratory illnesses provoke asthma exacerbations remains an unmet need.
Objective: To identify transcriptome-wide gene expression changes associated with colds that progress to exacerbation.
Methods: 208 urban children (6-17 years) with exacerbation-prone asthma were prospectively monitored for up to two cold illnesses.

Background: Noninvasive mechanical ventilation (NIMV), when in synchronized intermittent mandatory ventilation, continuous positive airway pressure, or patient-triggered ventilation modes, is known to be a cause of facial, nasal, head, and skin pressure injuries in preterm infants.
Objective: The objective of this study is to examine the efficacy of using a checklist with preterm infants under nasal NIMV in preventing facial, nasal, and head pressure injuries.
Method: The study was conducted quasi-experimentally on preterm infants under NIMV.

Background And Objective: Septoplasty and turbinate reduction surgery (STR) is hypothesized to affect pulmonary function by modifying airway dynamics. This study investigates the impact of STR-mediated improvements in nasal patency on pulmonary function tests (PFTs).
Methods: In a prospective analysis, 37 adult patients undergoing STR were enrolled.
Airway pressures generated by high flow nasal cannula in patients with acute hypoxemic respiratory failure: a computational study.

Introduction And Objectives: High flow nasal cannula (HFNC) therapy is an increasingly popular mode of non-invasive respiratory support for the treatment of patients with acute hypoxemic respiratory failure (AHRF). Previous experimental studies in healthy subjects have established that HFNC generates flow-dependent positive airway pressures, but no data is available on the levels of mean airway pressure (mP) or positive end-expiratory pressure (PEEP) generated by HFNC therapy in AHRF patients. We aimed to estimate the airway pressures generated by HFNC at different flow rates in patients with AHRF, whose functional lung volume may be significantly reduced compared to healthy subjects due to alveolar consolidation and/or collapse.
