BACKGROUND Endobronchial tuberculosis (EBTB) is a serious form of pulmonary tuberculosis. In EBTB, mycobacterium tuberculosis involves trachea, large airways and bronchial trees Combustion of biomass fuels causes anthracotic bronchitis that is characterized by black pigmentation in bronchial tissue. The majority of anthracotic bronchitis are in aged patients, particularly rural women, that use ...

The relation of chronic bronchitis and respiratory dysfunction to age, tobacco smoking, and occupational exposure to surface and underground mining operations were examined in a cross sectional survey of 1363 men employed in the Kalgoorlie mining industry in 1985. Overall, the prevalence of chronic bronchitis was 14%. Eleven per cent of the workers had obstructive lung disorder (FEV1/FVC less t...

Airway eosinophilia and cough may be associated with asthma and with non-asthmatic eosinophilic bronchitis. Whether cough variant asthma and eosinophilic bronchitis are distinct entities or a pathophysiological spectrum needs further examination.

We discuss Bayesian estimation of a logistic regression model with an unknown threshold limiting value (TLV). In these models it is assumed that there is no effect of a covariate on the response under a certain unknown TLV. The estimation of these models in a Bayesian context by Markov chain Monte Carlo (MCMC) methods is considered with focus on the TLV. We extend the model by accounting for me...

Current guidelines recommend severity of chronic obstructive pulmonary disease be graded by using forced expiratory volume in 1 s (FEV1). But this measurement is biased by thoracic gas compression depending on lung volume and airflow resistance. The aim of this study was to test the hypothesis that the effect of thoracic gas compression on FEV1 is greater in emphysema than chronic bronchitis be...

BACKGROUND in order to describe the prevalence and prognostic implications of chronic bronchitis in individuals 65 years or older we analysed data from The Copenhagen City Heart Study. METHODS the population was studied in 1976-1978 resurveyed in 1981-1983 and 1991-1994 and followed with regard to survival for up to 12 years. Approximately 3,700 elderly participants with a mean age of 76 year...

Acute bronchitis is a predominantly viral illness and, according to clinical practice guidelines, should not be treated with antibiotics. Despite clear guidelines, acute bronchitis continues to be the most common acute respiratory illness for which antibiotics are incorrectly prescribed. Although the national benchmark for antibiotic prescribing for adults with acute bronchitis is 0%, a prelimi...

INTRODUCTION Although several clinical prediction rules exist for lower respiratory tract infection (LRTI), few are for acute bronchitis (acute bronchitis) and most have not been validated in high human immunodeficiency virus (HIV) prevalence settings. METHODS An Acute Bronchitis Severity Score (ABSS) was developed and validated during a randomized trial of antibiotic treatment for acute bron...
