the broader category of chronic obstructive pulmonary disease (COPD), which is characterized by a chronic, predominantly irreversible reduction in maximal airflow velocity. Chronic bronchitis, emphysema, asthma, and to a lesser extent bronchiectasis comprise the majority of COPD (Figure 1). Chronic bronchitis is a disease process identified clinically as the presence of a productive cough on mo...

BACKGROUND & OBJECTIVES Exposure to air pollution due to combustion of biomass fuels remains one of the significant risk factors for chronic respiratory diseases such as chronic bronchitis. There is a need to identify the minimum threshold level of biomass index that is significantly associated with chronic bronchitis. This study was undertaken to identify a threshold for biomass exposure index...

1. Airways resistance and lung volume were measured in twenty-five patients with chronic bronchitis and fifteen patients without chest disease before and after the inhalation of isoprenaline. Similar measurements were made on fourteen of these patients with chronic bronchitis and twelve other patients without chest disease before and after the intravenous injection of atropine sulphate. 2. Ther...

Chronic bronchitis is responsible for a greater annual mortality in Great Britain than any other single respiratory disease, and its incidence is far higher in this country than anywhere else in the world (Oswald, 1958), yet relatively few comprehensive studies of the pathogenesis of the condition have been published. Considerable attention has been paid recently to the factor of infection in c...

BACKGROUND AND PURPOSE Acute and several chronic infectious diseases increase the risk of stroke. We tested the hypothesis that chronic bronchitis and frequent flu-like illnesses are independently associated with the risk of stroke or transient ischemic attack (TIA). METHODS We assessed symptoms of chronic bronchitis, frequency of flu-like illnesses, and behavior during acute febrile infectio...

BACKGROUND Eosinophilic inflammation of the airway is usually associated with airway hyper-responsiveness in bronchial asthma. However, there is a small group of patients which has the eosinophilic inflammation in the bronchial tree with normal spirometry and no evidence of airway hyper-responsiveness, which was named eosinophilic bronchitis. The objectives of this study are 1) to investigate t...
