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)
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)
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)
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)
BACKGROUND Late asthmatic response is observed following antigen challenge in actively, but not passively, sensitized guinea pigs. Although cough reflex sensitivity is increased after antigen challenge in actively sensitized guinea pigs, it is unknown whether the antigen-induced increase in cough reflex sensitivity develops in passively sensitized animals.(More)
BACKGROUND It has been reported that nasal allergy influences the lower airway inflammation and functions. We elucidated whether nasal allergy would contribute to lower airway inflammation and functions. METHODS 266 subjects aged 21-39 years were interviewed with special emphasis on history of asthma and nasal allergies (perennial allergic rhinitis (PAR)(More)
OBJECTIVE To investigate the distribution of anti-aminoacyl-tRNA synthetase (anti-ARS) antibodies among patients with autoimmune diseases, and to analyze the clinical features of patients with dermatomyositis (DM) with anti-ARS antibodies. METHODS Serum samples from 315 patients with autoimmune diseases or related disorders who had visited Kanazawa(More)
Primary malignant tumors of the pulmonary arteries occur infrequently. The clinical presentation and diagnostic imaging features of the tumor are usually nonspecific and correct diagnosis is often delayed. In this report, we present a case of pulmonary artery sarcoma. MRI and PET-CT were found to be useful for differentiating the tumor from a(More)
RATIONALE We hypothesized that cough stress of the airway wall results in a self-perpetuating cough-reflex cycle in which antigen-induced increase in cough-reflex sensitivity results in pathologic cough, and the cough in turn further amplifies cough-reflex sensitivity. OBJECTIVES To examine cough-reflex sensitivity in an experimental animal model. (More)
BACKGROUND The clinical features of pneumocystis pneumonia (PCP) differ according to the predisposing factors responsible for immunosuppression. Although PCP in patients with acquired immunodeficiency syndrome (AIDS) has been extensively described, its characteristics in non-AIDS patients, such as those with malignancies, are not thoroughly documented.
