The physiological and clinical effects of noninvasive ventilation (NIV) on acute postoperative respiratory failure are relatively unknown. The aim of this study was to determine the prediction factors for failure in the use of NIV with a helmet in this context. ⋯ NIV using a helmet could provide an effective alternative to conventional ventilation in selected patients with postoperative ARF.

A negative sputum smear from a patient with history, physical examination, and chest x-ray findings suggestive of tuberculosis (TB) presents a diagnostic dilemma. We investigated the possible factors associated with a misdiagnosis and inappropriate treatment of TB among such patients. ⋯ An incorrect diagnosis of TB despite a negative sputum smear result is more likely to be made for patients positive for nontuberculous mycobacteria culture and less likely for patients with positive M. tuberculosis culture.

Case Reports Comparative Study
Use of an endoscopy face mask in patients with gastric distention undergoing noninvasive ventilation for acute respiratory failure: a comparative case study report.
We describe the use of an endoscopy face mask with a perforated membrane, which allows a nasogastric tube for continuous noninvasive ventilation in acute hypercapnic respiratory failure, in 2 patients who developed gastric distention. This interface was able to avoid most nonintentional leaks through the mask, as compared with a conventional approach, improving ventilation efficiency. To our knowledge, this is the first case report of an endoscopy face mask used in noninvasive ventilation for this specific side effect.

Case Reports
An in-patient model for positive airway pressure desensitization: a report of 2 pediatric cases.
Application of positive airway pressure is frequently indicated in pediatric patients with a diagnosis of obstructive sleep apnea. Adherence to equipment use is often less than optimal and can be more challenging when working with children with special needs. An in-patient protocol was designed utilizing various techniques and strategies from the medical adherence literature and applied to 2 cases. ⋯ This paper outlines this protocol using 2 case studies. Both patients successfully used their equipment for greater than 4 hours at night by the end of their hospital stay of 4 days and maintained or advanced these gains at follow-up. These 2 cases suggest that more research should be conducted to further evaluate the effectiveness of similar programs.

The functional role of the human diffuse panbronchiolitis critical region 1 (DPCR1) gene, located in the major histocompatibility complex class I, has not been widely investigated. However, this gene is a well known genetic marker for diffuse panbronchiolitis, a disease affecting human respiratory bronchioles. In this study we explored the association between polymorphisms in DPCR1 and aspirin-exacerbated respiratory disease (AERD), an asthma phenotype. ⋯ Our results show that polymorphisms in DPCR1 are not associated with the risk of AERD.
