Review Case Reports
Necrotizing sarcoid granulomatosis with an uncommon manifestation: clinicopathological features and review of literature.
We report a rare case of an incidental diagnosis of necrotizing sarcoid granulomatosis (NSG) in a 60-y-old non-smoking male. The patient was admitted to the hospital for sudden back pain. Chest x-ray revealed areas of parenchymal consolidation and high-resolution computed tomography demonstrated a pulmonary nodular pattern with no lymph node enlargement. ⋯ The diagnosis of NSG was made by histopathological examination of a surgical lung biopsy and by excluding other causes of granulomatous disease. In paucisymptomatic/asymptomatic patients, as in our case, therapy is not necessary, with a good prognosis and complete recovery. NSG is a rare systemic disease similar to sarcoidosis and Wegener's granulomatosis with a benign clinical course and should always be considered for patients with nodular pulmonary lesions even with subclinical or uncommon features.

Accumulation of secretions may suddenly occlude an endotracheal tube (ETT), requiring immediate medical attention. The endOclear catheter (Endoclear LLC, Petoskey, Michigan) is a novel device designed to clear mucus and debris from an ETT and restore luminal patency. ⋯ The respiratory conditions rapidly improved, and all 3 patients tolerated the ETT-cleaning maneuver. These results show that such a device is safe and easy to use during an emergency airway situation for efficient and rapid removal of secretions from obstructed ETTs by respiratory therapists.

The clinical implications of fractional exhaled nitric oxide (F(ENO)) measurements in childhood asthma are unclear. We aimed to evaluate the relationship between the level of exhaled nitric oxide and pre-bronchodilator FEV1 and the change in FEV1 after bronchodilator in children with asthma. ⋯ Our results suggest a need to measure F(ENO) before as well as after spirometry. Consequently, in children with asthma with bronchial obstruction, we suggest assessing F(ENO) after short-acting β2 agonists as well. (ClinicalTrials.gov registration NCT00815984.).

Normal values of the 6-min walk distance (6MWD) for children have not been well demonstrated. This limits the interpretation of the 6MWD in children. ⋯ The 6MWD does not increase in a straight linear fashion from the age of 12 until adulthood. Correlation of the 6MWD with anthropometric features is very weak, so in evaluating the 6MWD, the standard curves should be used.

Daytime mouthpiece ventilation is a useful adjunct to nocturnal noninvasive ventilation (NIV) in patients with neuromuscular disease. The aims of the study were to analyze the practice of mouthpiece ventilation and to evaluate the performance of ventilators for mouthpiece ventilation. ⋯ Subjects are satisfied with mouthpiece ventilation. Alarms are common with home ventilators, although less common in those with mouthpiece ventilation software. Improvements in home ventilators are needed to facilitate the expansion of mouthpiece ventilation.
