Case Reports[Large-cell carcinoma presenting as diffuse thickening of the pleura and resembling malignant mesothelioma].
A 65-year-old man had a right-sided pleural effusion. A thoracic CT scan revealed diffuse pleural thickening resembling malignant mesothelioma. ⋯ Hyalinized fibrous tissue with malignant cell infiltration was seen in the thickened pleural tissue and metastatic pleuritis was diagnosed. Large-cell carcinoma of the lung should be considered in the differential diagnosis of pleural thickening.

Case Reports[Central sleep apnea syndrome successfully treated with nasal bi-level positive airway pressure and sleep position adjustment].
A 55-year-old obese man was admitted to our hospital because of a severe morning headache. He snored and had recurrent episodes of sleep apnea that began 10 years earlier and had since become much worse. An overnight polysomnographic recording confirmed that he had sleep apnea syndrome, predominantly of the central type. ⋯ He was treated with sleep position adjustment and nasal bi-level positive airway pressure, inspiratory positive airway pressure at 5 cmH2O and expiratory positive airway pressure at 2 cmH2O. His snoring, headache, and oxygen desaturation resolved. This case suggests that airway collapse may cause central apnea, and that nasal continuous positive airway pressure, and nasal bi-level positive airway pressure and adjustment of sleep position can be effective in some patients with central-type sleep apnea syndrome.

Case Reports[Three cases of malignant lymphoma that developed from the chest wall].
Chronic tuberculous pyothrax and the development of non-Hodgkin's lymphoma (NHL) on the chest wall are believed to be closely related. We encountered three patients with NHL involving the chest wall in whom the tumor may have had a different origin Patient 1: A 65-year-old man with a history of pulmonary tuberculosis and right-sided pyothrax at the age of 28 years was found to have a tumor on the right sided of the chest wall, and NHL was diagnosed. ⋯ In patients 1 and 2, the Epstein-Barr virus was found in tissue specimens by in situ hybridization. These findings suggest that chronic tuberculous pyothrax and the development of NHL on the chest wall were not closely related in these patients, and that the Epstein-Barr virus may play an important role in the development of NHL on the chest wall after tuberculous pyothrax.

[Effect of smoking on the decline in forced expiratory volume in one second].
We used multiple regression analysis to study the effects of smoking cessation on the decline in forced expiratory volume in one second (FEV1). We studied 429 healthy men for about 3 years. ⋯ Having stopped smoking was associated with a slower decline in FEV1. The rate of decline in MMF was associated with the rate of decline in FEV1, which suggests that the rate of decline in FEV1 was greater in those subjects with small airways disease.

Case Reports[Alveolar hemorrhage and glomerulonephritis in two patients with anti-neutrophil cytoplasmic antibodies].
A 55-year-old woman and a 56-year-old woman were admitted to the hospital because of dyspnea on exertion and bloody sputum. Chest roentgenography and computed tomography showed bilateral infiltrative shadows. Examination of bronchoalveolar lavage fluid and of specimens obtained by transbronchial lung biopsy revealed alveolar hemorrhage and hemosiderin-laden macrophages. ⋯ Test for anti-neutrophil cytoplasmic antibody (ANCA) were positive; alveolar hemorrhage and glomerulonephritis accompanied by ANCA-related vasculitis was diagnosed. The patients' condition improved with administration of prednisolone and cyclophosphamide. Measurement of ANCA was useful for monitoring the activity of the disease.
