OBJECTIVE Community-acquired pneumonia (CAP) remains a major cause of death. No studies have reported the use of rapid influenza diagnostic tests (RIDT) for the etiological diagnosis, and the factors contributing to severity and mortality have not yet been fully investigated. The aim of this study was to review the etiologies of CAP using RIDT and to(More)
A 54-year-old woman was admitted for cough, sputum, and an abnormal chest X-ray shadow. Bronchoscopy showed mucoid impaction of the bronchi (MIB). Histopathologic evidence of mucous plugs was consistent with one component of allergic bronchopulmonary mycosis. Schizophyllum commune (S. commune) was identified. Two attempts at removal of the mucous plugs were(More)
AIMS The aim was to clarify the pleuropulmonary pathological findings of vascular Ehlers-Danlos syndrome (vEDS). METHODS AND RESULTS Nine patients with confirmed vEDS by means of cell culture and/or molecular biological studies who had undergone surgical lung biopsy (SLB), lobectomy or autopsy were studied. Six patients were male and three were female(More)
A 17-year-old-man developed left-sided pneumothorax in 1995. Chest computed tomography (CT) showed a thick-walled cavity in the left lower lobe. Video-assisted thoracic surgery was performed, and pathologic findings of the resected lung showed a cavity, organizing hematoma, and a fibrous nodule. Fragility of connective tissue was suspected, and biochemical(More)
A 57-year old man with desquamative interstitial pneumonia (DIP) showed a marked increase in eosinophils in the bronchoalveolar lavage (BAL) fluid. The patient was referred to our hospital for abnormal shadows on his chest X-ray with no symptoms in May 2007. Computed tomography (CT) showed patchy, peripheral predominate ground-glass opacity. The BAL fluid(More)
A 43-year-old man with chronic renal failure who had been treated by continuous ambulatory peritoneal dialysis (CAPD) was admitted to our hospital because of dry cough. Blood gas analysis showed hypoxemia and metabolic alkalosis. Laboratory data showed elevated levels of phosphorus, BNP, and KL-6. Lung function tests showed restrictive ventilatory failure(More)
A 37-year-old man was admitted with complaints of continuous cough and sputum production for 1 month. Computed tomography (CT) of the chest revealed a solitary mass with a cavity in the apex of the left lung and bilateral ground-glass opacities (GGO). Thereafter, the patient complained of fever, and an increase in the mass shadow size and expansion of the(More)
A 20-year-old man was referred to our hospital due to hemoptysis. Chest CT showed a ground-glass opacity, suggesting pulmonary bleeding; however, a diagnosis was not obtained. At a follow-up examination after 2 months, Chest CT showed improvement of the ground-glass opacity, however a cavitary nodule had newly appeared. Four months later, another new nodule(More)
A 73-year-old woman presented to our hospital with scleritis, cough, and hemoptysis. Chest computed tomography showed a mass lesion, multiple ground-glass opacities, and nodules. Bronchoscopy showed a skip lesion of mucosal erosion with white necrotic substance; however, a biopsy specimen of the erosion yielded no characteristic findings. Transbronchial(More)
