BACKGROUND Little is known about the effect of exposure to cooking oil fumes (COFs) on the development of non-malignant respiratory diseases in nonsmoking women. This study investigated the relationship between exposure to COFs and chronic bronchitis in female Taiwanese non-smokers. METHODS Searching the 1999 claims and registration records maintained by Taiwan's National Health Insurance Pro...

Airway inflammation during infection is associated with increased transudation of serum proteins and increased production of protein by the airway epithelium. We therefore, assessed whether Haemophilus influenzae infections in patients with chronic bronchitis are associated with increased levels of transferrin and lactoferrin in the sputum compared to uninfected patients. Sputum sol phase and s...

A survey for the prevalence of chronic bronchitis in an industrial population in North India is reported. The prevalence of chronic bronchitis is 12.5 percent in 473 subjects between the ages of 17 and 64 years. The prevalence rate of chronic bronchitis is comparable to that observed in areas of low community air pollution in Europe and North America. There is no age-related rise in the frequen...

BACKGROUND Several studies have indicated that one of the most potent mediators involved in pulmonary vascular remodeling is vascular endothelial growth factor (VEGF). This study was designed to determine whether airway VEGF level reflects pulmonary vascular remodeling in patients with bronchitis-type of COPD. METHODS VEGF levels in induced sputum were examined in 23 control subjects (12 non-...

The present study investigated the relationship between socioeconomic status, using measures of occupational class and education level, and the prevalence and incidence of asthma (with and without atopy) and chronic bronchitis using data from the European Community Respiratory Health Survey (ECRHS). Asthma and chronic bronchitis were studied prospectively within the ECRHS (n = 9,023). Incidence...

Infectious bronchitis is an acute viral disease with high contagious and mortality among chicks. The aim of this study was to survey of relation between ascites syndrome incidence and infectious bronchitis in broiler chickens by ELISA method in Iran. Eight Ross strain broiler farm affected by infectious bronchitis were selected in this study. Blood samples were gathered early stages of disease ...

Waterpipe smoking and its association with chronic bronchitis has not been assessed in Lebanon. This case-control study in Beirut in 2009/2010 evaluated this relationship: 274 cases of chronic bronchitis and 559 controls without the condition aged > or = 40 years were enrolled. Data were collected by questionnaire on: sociodemographic characteristics, respiratory symptoms, smoking (waterpipe an...

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 Cigarette smoking cannot fully explain the epidemiologic characteristics of chronic obstructive pulmonary disease (COPD) in women, particularly for those who rarely smoke, but COPD risk is not less than men. The aim of our study is to investigate the relationship between second-hand smoke (SHS) exposure and chronic bronchitis in Taiwanese women. METHODS We used Taiwan's National He...

1. Measurements of airways resistance and lung volume were made in sixteen patients with chronic bronchitis and ten patients without chest disease before and after intravenous propranolol administration. 2. The airways resistance of the patients with chronic bronchitis increased significantly after propranolol administration but in the control subjects there was no significant increase. 3. In t...
