Chest x-ray (CXR) is widely used for diagnosing and screening pulmonary tuberculosis (PTB), yet its validity is debatable and its costs are relatively high. This study aimed to determine the validity of CXR screening in detecting radiological findings compatible with active PTB or with old healed tuberculosis (OHTB). ⋯ CXR is a valid and cost-saving tool for screening active PTB in immigrants originating in high-burden countries, and is beneficial in detecting OHTB in immigrants who are at a higher risk for developing active PTB.

We report an 18-year-old ice skater with acute lymphoblast leukemia. She developed Staphylococcus epidermidis bacteremia, severe sepsis, septic shock, and ARDS following chemotherapy-induced severe bone marrow failure. She was successfully treated with extraordinary life support measures, which included extracorporeal membrane oxygenation, double lumen lung ventilation for management of hemoptysis, and lung assist membrane ventilation. After 57 days of ICU treatment and a year of rehabilitation, the patient has fully regained her functional status, is now finishing high school, and is ice skating again.

Oxygen therapy is an important therapeutic resource for patients with hypoxemia. When changing oxygen flow meters, we have observed that sometimes, even with the same oxygen flow setting as before, a different S(pO(2)) is obtained. ⋯ The flow meters tested showed good precision and poor accuracy.

Previous research reporting factors influencing aerosol delivery in intubated patients has been largely focused on the endotracheal tube (ETT) during mechanical ventilation, with little comparative analysis of effect of types of artificial airways and their interfaces on aerosol delivery during spontaneous breathing. The purpose of this study was to compare aerosol delivery via tracheostomy tube (TT) and ETT, using interfaces such as T-piece, tracheostomy collar, and manual resuscitation bag. ⋯ In this adult model of spontaneous ventilation, aerosol therapy through ETT was less efficient than TT, while the manual resuscitation bag was more efficient than T-piece or tracheostomy collar.

Co-existence of catamenial pneumothorax and hemoptysis is rare. We present a case of catamenial pneumothorax due to bilateral pulmonary endometriosis in a 45-year-old woman. The patient presented with a 3-year history of intermittent productive cough with blood-tinged sputum, chronic anemia, loss of appetite, and general weakness associated with menstruation. ⋯ CT-guided biopsy revealed chronic inflammation of those pulmonary nodules, and laboratory studies disclosed elevated serum levels of carbohydrate antigen 19-9 (CA 19-9) and CA 125. Thoracoscopic wedge resection of the pulmonary nodules was performed, and histopathological examination of the resected nodules revealed endometriosis. At one-year follow-up there was no evidence of recurrence of gastrointestinal bleeding or pneumothorax.
