A 62-year-old man had felt cold-like symptoms for 2 months. He visited a clinic for a health check in late July 1998 and chest X-ray film showed an infiltrative shadow in the left middle and lower lung fields. Next day he had a fever of 38.3 degrees C and felt breathless. Six days thereafter he had a cough, thick head and felt fatigue. Chest X-ray films(More)
OBJECTIVES To clarify clinico-pathological features of tuberculosis found at autopsy. METHODS This study investigates 18 (3.7%) of active pulmonary tuberculosis out of 489 autopsy in Tachikawa Sougo Hospital during the period from 1992 to 2005. RESULTS There were 11 men and 7 women, with a median age of 69.5 years. Tubercle bacilli were proved from(More)
Expiratory flow limitation (EFL) during tidal breathing is common in patients with severe COPD, and a major determinant of dynamic hyperinflation and exercise limitation. The negative expiratory pressure (NEP) technique has been the gold standard to detect EFL, while the forced oscillation technique (FOT) has also been reported to detect it. However, the(More)
Since the landmark study of the natural history of chronic obstructive pulmonary disease (COPD) by FLETCHER and PETO [1], lung function decline has been an issue of great concern and an important therapeutic target. The annual decline in forced expiratory volume in 1 s (FEV1) is generally used as a marker of disease progression. A review of large(More)
The usefulness of the forced oscillation technique (FOT) for predicting the treatment outcomes in untreated asthmatic patients is unknown. We investigated whether FOT could predict an improvement in FEV1 following treatment. FOT, spirometry, and fractional exhaled nitric oxide were performed in 31 outpatients before and after undergoing a minimum of two(More)
