Club cell secretory protein (CCSP) is a protective biomarker associated with annual decline in lung function. COPD progression results from an imbalance between injury and repair initially triggered by cigarette smoking. ⋯ In vitro, rhCCSP exogenous supplementation can reverse CSE-induced IL-8 release in biopsy specimens from patients with COPD, indicating a potential use of this strategy in vivo.

Technique for repair of fractures and separations involving the cartilaginous portions of the anterior chest wall.
Internal fixation of the ribs has been shown in numerous studies to decrease complications following traumatic rib fractures. Anterior injuries to the chest wall causing cartilaginous fractures, although rare, can cause significant disability and can lead to a variety of complications and, therefore, pose a unique clinical problem. ⋯ All patients had excellent clinical outcomes and reported improvement in symptoms, with no associated complications. Patients who have injuries to the anterior portions of the chest wall should be considered for internal fixation of the chest wall when the injuries are severe and can lead to clinical disability.

Inflammation may contribute to the pathobiology of pulmonary arterial hypertension (PAH). Deciphering the PAH fingerprint on the inflammation orchestrated by dendritic cells (DCs) and T cells, key driver and effector cells, respectively, of the immune system, may allow the identification of immunopathologic approaches to PAH management. ⋯ We have highlighted T helper 17 cell immune polarization in patients with PAH, as has been previously demonstrated in other chronic inflammatory and autoimmune conditions.

Case Reports
29-year-old man presenting with progressive dyspnea, oculocutaneous albinism, and epistaxis.
A 29-year-old man with a history of oculocutaneous albinism presented to the ED complaining of progressive dyspnea on exertion. One month prior to admission, the patient had begun to experience worsening dyspnea provoked by routine household activities. Additionally, he had developed a nonproductive cough, exacerbated by cold weather. ⋯ A review of systems was significant for a history of epistaxis and frequent bruising. Born in Honduras, he had immigrated to the United States approximately 10 years prior to his presentation to our facility. Furthermore, there was no family history of albinism, bleeding disorders, or pulmonary disease.

Comparative Study Observational Study
Comparison of a self-inflating bulb syringe and a colorimetric carbon dioxide indicator with capnography and radiography to detect the misdirection of naso-orogastric tubes into the airway of critically ill adult patients.
The objective of this study was to develop a mechanism of discovering misdirection into the airway of naso/orogastric (NG) tubes before they reach their full depth of placement in adults. ⋯ The SIBS and the colorimetric CO2 detector are very good at detecting NG tube malpositioning into the airway, although the colorimetric device is slightly more sensitive and specific. Neither method adds substantial time or difficulty to the insertion process. The colorimetric device is substantially more expensive. The decision as to which method to use may be based on local institutional factors, such as expense.
