A 39-year-old man, who had been working in an aluminum processing industry for 18 years, visited our hospital for right chest pain on March 2, 2007. A relapse of right pneumothorax was found, and he was hospitalized. As the pneumothorax did not improve with conservative treatment, video-assisted thoracoscopic biopsy and suturing of the right upper lobe were(More)
A 90-year old man was admitted to a hospital because of consciousness loss with hyponatremia. Although his symptom promptly improved with Na supply, his chest X-ray film showed pulmonary infiltration and direct microscopy of sputum smear was positive for acid-fast bacilli, then he was referred our hospital and was admitted. We made a clinical diagnosis of(More)
Recently, great attention has been drawn to IgG4-related diseases such as autoimmune pancreatitis (AIP) sclerosing sialadenitis, retroperitoneum fibrosis, sclerosing cholangitis. IgG4-related diseases are characterized by high serum IgG4 concentrations, sclerosing inflammation with numerous IgG4-positive plasma cells, and steroid sensitivity irrespective of(More)
PURPOSE To retrospectively analyze radiologic findings of immunoglobulin G4 (IgG4)-related lung disease as correlated with pathologic specimens. MATERIALS AND METHODS This study was approved by the institutional review board, and all patients had consented to the use of their medical records for the purpose of research. This study included 13 patients(More)
We report a successful case of living-donor lobar lung transplantation (LDLLT) for therapy-resistant broncho-bronchiolitis obliterans (BBO) after allogeneic hematopoietic stem cell transplantation (HSCT). Bronchiolitis obliterans (BO) is one of the late-onset noninfectious pulmonary complications that occur after allogeneic HSCT and is usually resistant to(More)
BACKGROUND The role of angiotensin II type 2 receptor (AT2) in pulmonary fibrosis is unknown. To evaluate the influence of angiotensin II type 1 receptor (AT1) and AT2 antagonists in a mouse model of bleomycin (BLM)-induced pulmonary fibrosis. METHODS We examined effects of the AT1 antagonist (AT1A) olmesartan medoxomil (olmesartan) and the AT2 antagonist(More)
The development of bleomycin-induced lung injury, a model of pulmonary fibrosis, results from inflammatory cell infiltration, a process highly regulated by the expression of multiple adhesion molecules. At present, the identity and role of the adhesion molecules involved in the fibrotic process are unknown. Therefore, bleomycin-induced pulmonary fibrosis(More)
Pulmonary blood flow is reflected in dynamic chest radiographs as changes in X-ray translucency, i.e., pixel values. Thus, decreased blood flow should be observed as a reduction of the variation of X-ray translucency. We performed the present study to investigate the feasibility of pulmonary blood flow evaluation with a dynamic flat-panel detector (FPD).(More)
OBJECTIVES Dynamic flat panel detectors (FPD) permit acquisition of distortion-free radiographs with a large field of view and high image quality. The present study was performed to evaluate pulmonary function using breathing chest radiography with a dynamic FPD. We report primary results of a clinical study and computer algorithm for quantifying and(More)
We describe a 73-year-old woman with systemic sclerosis (SSc)-polymyositis (PM) overlap syndrome, primarily SSc followed by PM. She had suffered from SSc and had interstitial pneumonia (IP), which was stable. Eight years after the initial diagnosis of SSc, proximal muscle weakness, myalgia, and dyspnea on effort developed. A chest computed tomography (CT)(More)
