Case Reports
Necrotizing Tracheitis secondary to Corynebacterium species presenting with Central Airway Obstruction.
Pseudomembranous necrotizing tracheitis is a rare cause of life-threatening central airway obstruction. Patients present with hoarseness, cough, dyspnea, wheezing, stridor, and occasionally with respiratory failure. ⋯ For patients with signs and symptoms of airway obstruction, a therapeutic rigid bronchoscopy with mechanical debridement is recommended. We present a rare case of necrotizing tracheitis secondary to Corynebacterium species, which caused life-threatening airway obstruction in an adult.

Randomized Controlled Trial Comparative Study
Heated humidification improves clinical outcomes compared to a heat-and-moisture exchanger in children with tracheostomies.
The upper airway humidifies and warms inspired gases before they reach the trachea, a process bypassed by the insertion of a tracheostomy, necessitating humidification of inspired gases. The optimal method of humidification is not known. ⋯ Over 20 hours use, HH, compared to HME, improved work of breathing. Over a longer 10 week treatment period HH resulted in decreased adverse clinical events.

Comparative Study
Effect of High Flow Nasal Cannula on Thoraco-abdominal Synchrony in Adult Critically Ill Patients.
High-flow nasal cannula (HFNC) creates positive oropharyngeal airway pressure and improves oxygenation. It remains unclear, however, whether HFNC improves thoraco-abdominal synchrony in patients with mild to moderate respiratory failure. Using respiratory inductive plethysmography, we investigated the effects of HFNC on thoraco-abdominal synchrony. ⋯ HFNC improved thoraco-abdominal synchrony in adult subjects with mild to moderate respiratory failure.

There are few studies using animal models in chest physical therapy. However, there are no models to assess these effects in newborns. This study aimed to develop a model of obstructive atelectasis induced by artificial mucus injection in the lungs of newborn piglets, for the study of neonatal physiotherapy. ⋯ Our model of atelectasis in newborn piglets is both feasible and appropriate to evaluate the impact of physical therapies on atelectasis in newborns.
