The epidemiology of chronic obstructive pulmonary disease (COPD) has been dominated by one hypothesis stating that cigarette smoking and chronic bronchitis were the key to pathogenesis and another that asthma, chronic bronchitis, and even emphysema are related to different expressions of a primary airway abnormality. The first hypothesis was rejected in the late 1960s based on a longitudinal st...
An epidemiological study was performed with a self administered questionnaire in a representative sample of 1685 Danish farmers. The purpose of the study was to assess the prevalence of self reported asthma, wheezing during work, and symptoms of chronic bronchitis and to evaluate possible risk factors for the development of these symptoms. A response rate of 73.3% was obtained. The prevalence o...
Increasing evidence suggests that vitamin D benefits both innate and adaptive immunity, thereby eliciting an anti-inflammatory effect and reducing the risk of infectious disease. The present study examined the association between serum 25-hydroxyvitamin D (25(OH)D) levels and the risk of chronic bronchitis among US adults. We analysed data from 6872 US adults aged ≥ 20 years who participated in...
INDICATIONS Tulobuterol is indicated for prophylaxis and control of bronchospasm in bronchial asthma, chronic bronchitis, asthmatic bronchitis, pulmonary emphysema, bronchiectasis, tracheobronchitis with emphysema and other bronchospastic disorders and conditions characterized by bronchoconstriction. Because oral tulobuterol is long acting, it is ideally suited for routine maintenance therapy i...
The ventricular weights in 43 patients with interstitial pulmonary fibrosis were retrospectively compared with those in 172 patients with emphysema and chronic bronchitis. The mean right ventricular weight of patients with interstitial pulmonary fibrosis and those with emphysema and chronic bronchitis was 85.5 g (SD 23.2) and 88.8 g (34.3), respectively. Thirty five patients (81%) with intersti...
Materials and methods A retrospective case-control study was performed. Industry workers from an oil refinery were monitored for a 6yrs period. The air levels of aliphatic and aromatic hydrocarbons were monitored. During this period, all workers received regular clinical examinations, which included evaluation for smoking status, occupational exposure to hydrocarbons (aliphatic and aromatic), a...
CHEST / 89 / 3 / MARCH, 1986 321 Oxidant Damage by Leukocytes T he pathogenesis of chronic bronchitis remains poorly understood. Particularly significant is our lack of understanding of why only a minority of patients with “simple” chronic bronchitis progress to the advanced form of the disease with chronic airflow obstruction. Much of our knowledge of this disease is derived from morphologic s...
Bronchograms were made in eight men, chosen on clinical grounds as representative of three grades of severity in a series of 67 male bronchitis studied prospectively over a period of 10 years, with the object of ascertaining the anatomical condition at the end of this period. In the stationary group the bronchograms showed only a mild mucous reaction, and peripheral filling was generally good. ...
A 58-year-old nonsmoker female was referred for evaluation of chronic cough of 13 months duration. After an initial work-up, the patient was diagnosed to have chronic cough due to eosinophilic bronchitis. The diagnostic work-up for eosinophilic bronchitis and bronchial biopsy is discussed. Eosinophilic bronchitis is differentiated from asthma. In addition, the patient developed dyspnea, flushin...
Pulmonary arterial hypertension represents an important parameter for the assessment of the severity of chronic bronchitis. The measurement of the pulmonary arterial pressure, however, requires invasive techniques of limited routine use because of costs and associated risks. The aim of this study is to evaluate whether the 81mKr right ventricular ejection fraction and parameters derived from eq...
