Patients with kyphoscoliosis and severe respiratory impairment frequently experience reduction in exercise tolerance, limitation in daily life activities, and deterioration in health-related quality of life (HRQOL). Noninvasive ventilation (NIV) as an add-on treatment to long-term oxygen therapy (LTOT) was shown to improve symptoms and HRQOL in these patients. Pulmonary rehabilitation can increase exercise capacity and HRQOL in patients with COPD, but its role in patients with restrictive thoracic disease, such as kyphoscoliosis, is uncertain. The aim of this study was to analyze the effects of combining pulmonary rehabilitation with LTOT and NIV treatments on arterial blood gases and the 6-min walk test (6MWT) in a homogeneous group of subjects with kyphoscoliosis. ⋯ A combined intervention including a tailored pulmonary rehabilitation program together with LTOT and NIV seems to be of short-term benefit in subjects with kyphoscoliosis and severe respiratory impairment.

The effect of pulmonary rehabilitation (PR) on the EuroQol Group's 5-dimension questionnaire (EQ-5D) in COPD has been poorly investigated. In addition, conflicting results were reported about the visual analog scale component of EQ-5D (EQ-VAS). The purpose of this study was to evaluate the responsiveness of EQ-VAS to PR and its relationship with clinical and functional parameters in subjects with COPD, as well as to define the minimal clinically important difference (MCID) estimate for the EQ-VAS after PR. ⋯ Our study shows that, in in-patients with stable moderate-to-severe COPD, EQ-VAS is a valid and reliable tool to assess the responsiveness to PR, with an estimated MCID of 8 points. The EQ-VAS can be a practical alternative to more time-consuming measures of health-related quality of life.

Case Reports
Exogenous Lipoid Pneumonia Successfully Treated With Bronchoscopic Segmental Lavage Therapy.
A 65-y-old Japanese man was referred to the respiratory medicine department because of abnormal radiologic findings. High-resolution chest computed tomography scans revealed a geographic distribution of ground-glass opacities and associated thickening of the interlobular septa (crazy-paving patterns) in both lower lobes. He had a habit of drinking 400-500 mL of milk and 400-800 mL of canned coffee with milk every day. ⋯ After the treatment, the radiologic findings improved in both lungs. The patient has not experienced a recurrence of lipoid pneumonia in 2 y to date. In conclusion, a case of exogenous lipoid pneumonia was successfully treated with bronchoscopic segmental lavage therapy.

The role of inflammation and immunity in COPD treatment is increasingly being recognized. The relationship between anti-inflammation/immunoregulation and emphysema in COPD lungs remains to be elucidated. The aim of this study was to investigate the effects of azithromycin (Azm) on the development of emphysema in smoking-induced COPD in rats. ⋯ Azm attenuates pulmonary emphysema by partly reversing the decrease in the numbers of inflammatory cells (neutrophil and macrophage) and VEGF secretion and VEGFR2 protein expression in smoking-induced COPD in rats.
