Gorham syndrome (massive osteolysis) is a very rare tumour-like lesion characterized by progressive osteolysis. The diagnosis must be confirmed by the microscopic finding of intramedullary angioma-like vascular structures. We report a case of a 15-year-old boy with a pathological fracture in his left humerus. Imaging modalities such as magnetic resonance(More)
A case of primary diffuse tracheobronchial amyloidosis in a 45-year-old woman is reported. Because of tracheal stenosis immediately beneath the vocal cords, due to amyloid deposits, she was treated with Nd-YAG laser irradiation. Immediately after treatment, symptoms such as cough, wheezing, and shortness of breath on exertion improved. Bronchoscopic Nd-YAG(More)
A 59-year-old male was admitted to our hospital in Jan. 1991 with complaints of general malaise and palpitation. Laboratory findings on admission showed anemia, thrombocytopenia and leukopenia consisted of 2.0% myeloblasts with Auerbodies. The bone marrow study showed granuloid hyperplasia with 45.5% myeloblasts. The diagnosis of acute myeloblastic leukemia(More)
CT findings following pneumonectomy were studied in 28 cases with lung cancer. A total of 53 CT images were evaluated in 13 right pneumonectomy cases and 15 left pneumonectomy patients. The postpneumonectomy pleural space (PS), thoracic space of the operated site (TS) and the thoracic space of the non-operated site (CTS) were measured at 3 slice levels of(More)
A 34-year-old woman was admitted to our hospital because of exertional dyspnea and ascites. Chest roentgenogram showed hyperinflation of the lung and diffuse reticular shadows. Abdominal CT showed retroperitoneal tumors. Ascites was considered to be chylous. These findings strongly suggested the diagnosis of pulmonary lymphangiomyomatosis. Under lumbar(More)
A 47-year-old woman was admitted for examination of massive right pleural effusion on chest radiography, together with chief complaints of dry cough and body weight loss. Exudative effusion was aspirated by thoracentesis, revealing many lymphocytes and a high level of adenosine deaminase. Thoracoscopy with local anesthesia was performed. Elevated white(More)
A retrospective follow-up study was conducted on patients with subacutely progressive interstitial pneumonia who underwent surgical biopsy. Pathologically, they were subclassified into subacute interstitial pneumonia (SIP) and SIP + F, which consisted of an SIP lesion and a focal usual interstitial pneumonia. The SIP group consisted of 35 cases and the SIP(More)
In this study, we empirically examine the effectiveness of regulatory actions on wastewater treatment plants in Illinois with careful attention to endogeneity issues that might have caused biased estimates in previous studies. We show that Pooled OLS and Fixed Effect models, which are the dominant estimation strategies in the literature, underestimate the(More)
