The expression of the glucocorticoid receptor (GR) in untreated or in steroid-dependent asthmatic patients is poorly understood. We therefore studied GR mRNA and protein levels in bronchial biopsies obtained from seven untreated asthmatic patients, seven control volunteers, and seven patients with chronic bronchitis. We also studied in bronchial epithelial cells obtained by brushing from 13 unt...

The role of fiberoptic bronchoscopy for rapid diagnosis of pulmonary tuberculosis was examined among 74 patients who were suspected of having the disease but had negative sputum smear for acid fast bacilli. Bronchial brushing and washing were routinely performed in all subjects and bronchial biopsy was performed on abnormal mucosa in 7 of them. The diagnosis of pulmonary tuberculosis was confir...

A 69 yr old female was hospitalized for further examination of abnormal shadows on chest radiographs. She had a history of tuberculous pleurisy, rheumatoid arthritis and gold-induced interstitial pneumonia. On admission she still suffered from rheumatoid arthritis. A chest computed tomography scan on admission showed clusters of small nodules in subpleural regions of both lungs combined with br...

Patients with cancer frequently develop pneumonitis for which no cause is documented ante mortem. Noninvasive diagnostic techniques, such as sputum induction, are generally inadequate, especially in myelosuppressed patients. To avoid pulmonary contamination with organisms colonizing the oronasopharynx and to obtain uncontaminated speciemens, 38 patients underwent bronchial brushing utilizing a ...

Obliterative bronchiolitis is commonly interpreted as chronic rejection and involves the bronchial and bronchiolar epithelium. Upregulation of major histocompatibility complex (MHC) II on bronchial epithelial cells (BEC) had been hypothesised to be an important trigger of a bronchus directed rejection response. More recently, the additional expression of the costimulatory molecules B7-1 (CD80) ...

Autoinfective strongyloidiasis is often fatal in immunosuppressed patients or in immunocomprised hosts. An interesting case of Strongyloides stercolaris hyperinfection was seen in an immunocompetent patient. This report describes a case of fatal strogyloidiasis in a 79 year old man, who had suffered gastrointestinal discomfort for years, and who presented because of respiratory illness. A chest...

OBJECTIVE To present a case of endobronchial metastasis from a seminoma mimicking a primary pulmonary mass on X-ray radiograph. CLINICAL PRESENTATION AND INTERVENTION A 27-year-old man presented with a 1-month history of hemoptysis. Thorax computerized tomography of the patient obtained at the level of the main right bronchi demonstrated a mass with a size of 7 x 6 cm and a peripheral lobulat...

OBJECTIVE The early diagnosis of chronic organ rejection after lung transplantation (LTx) is currently hampered by the lack of reliable diagnostic markers. The present study aims to establish the procedure of gene expression profiling in bronchial epithelial cells for the identification of candidate genes that might prove useful in the early diagnosis. METHODS Twenty-three patients who underw...
