RATIONALE The prognostic factors of Mycobacterium avium complex lung disease (MAC-LD) are not clearly defined. OBJECTIVES To assess the prognostic factors of all-cause and MAC-specific mortality in patients with MAC-LD, especially in accordance with radiographic features, first-line treatment, and host predisposition. METHODS Medical records of 634(More)
BACKGROUND AND OBJECTIVE In this study the prevalence, lung function and prognosis of IPF combined with emphysema were evaluated. METHODS Consecutive patients with usual interstitial pneumonia (UIP) on high-resolution computed tomography (HRCT), with or without emphysema, were assessed retrospectively. The area of fibrosis in the base of the lungs was(More)
BACKGROUND Anaerobes are the first and Streptococcus species the second most common cause of community-acquired lung abscess (CALA) in the West. The etiologic pathogens of this disease have changed in Taiwan, with Klebsiella pneumoniae being reported as the most common cause of CALA. OBJECTIVE To determine the etiologies of community-acquired lung(More)
BACKGROUND Increasing evidence indicates that antineutrophil cytoplasmic antibody (ANCA)-positive conversion occurs in patients initially diagnosed with idiopathic pulmonary fibrosis (IPF) and as a result, some of these patients develop microscopic polyangiitis (MPA). However, the incidence density of these patients is not well known. OBJECTIVES 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)
A 53-year-old man who had been suffering from asthma presented to our hospital because of abnormal shadows detected on a chest X-ray film during a routine medical examination. A biopsy specimen of a mucus plug obtained by bronchoscopy showed fungal hyphae, eosinophils, and Charcot-Leyden crystals, with evidence of lung tissue eosinophilia. Schizophyllum(More)
BACKGROUND COPD is defined by airflow limitation that is not fully reversible and is associated with relevant risk factors. The diagnosis requires that other causes of chronic airflow limitation (CAL) be excluded. We assessed the diagnostic utility of high resolution thoracic CT (HRCT) and bronchodilator reversibility to assist in making a diagnosis of(More)
OBJECTIVE Chronic Chlamydia pneumoniae infection has been identified serologically in patients with COPD. The aim of this study was to examine whether the severity of emphysema is related to elevated antibody titres against C. pneumoniae. METHODOLOGY We measured antibody titres against C. pneumoniae using ELISA, and assessed the severity of emphysema by(More)
BACKGROUND The purpose of this study was to examine changes in the airway lumen and parenchyma in relation to lung function in patients with chronic obstructive pulmonary disease (COPD) compared with controls. METHODS We studied 70 patients with COPD and 15 normal subjects. Using reconstructed computed tomography (CT) images, we traced the bronchial trees(More)
BACKGROUND AND OBJECTIVE In some patients, desquamative interstitial pneumonia may progress to lung fibrosis. The aim of this study was to assess the long-term radiological follow-up results in patients with desquamative interstitial pneumonia. METHODS Among 75 patients suspected of having desquamative interstitial pneumonia, 31 who fulfilled the criteria(More)
