Nontraumatic disruption of the fibrocartilaginous trachea is rare, and the appropriate management of this condition is not well-characterized. ⋯ Nontraumatic disruption of the fibrocartilaginous trachea occurs most commonly as a consequence of external beam RT. It can also occur as a complication of cervical and superior mediastinal operations or from A fumigatus-induced ulcerative tracheobronchitis post-lung transplantation. Although surgical treatment has been generally recommended for patients with this condition, patients with contained disruptions without evidence of pneumomediastinum may be managed nonoperatively.

Patients with obstructive sleep apnea (OSA) have a very high incidence of gastroesophageal reflux (GER). Previous studies have shown that the use of continuous positive airway pressure (CPAP) reduces the frequency of reflux events, but these studies only assessed the effect of a single night of treatment. The aim of this study was to assess the effect of 1 week of CPAP treatment on reflux in patients with OSA and GER. ⋯ In OSA patients with significant heartburn complaints, CPAP would appear to be an efficacious approach to the treatment of both disorders.

Obstructive sleep apnea syndrome (OSAS) is a known risk factor for hypertension in adults. This relationship is less clear in childhood OSAS. ⋯ The current study shows that increased DI contributed to the elevation of sleep DBP elevation.

Does quality of life of COPD patients as measured by the generic EuroQol five-dimension questionnaire differentiate between COPD severity stages?
To assess the discriminative properties of the EuroQol five-dimension questionnaire (EQ-5D) with respect to COPD severity according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria in a large multinational study. ⋯ Increasing severity of COPD was associated with a significant decline in EQ-5D VAS scores and utility scores. These results demonstrate that a generic instrument can assess COPD impact on quality of life and that the scores discriminate between patient groups of known severity. These utility scores will be useful in cost-effectiveness assessments.
