Respiratory symptoms and airflow limitation in asphalt workers

Respiratory symptoms and airflow limitation in asphalt workers.

BACKGROUND Asphalt workers are exposed to bitumen fume and vapour, and to exhaust from engines and passing traffic. AIMS To assess the occurrence of respiratory symptoms and signs of airflow limitations in a group of asphalt workers. METHODS All 64 asphalt workers and a reference group of 195 outdoor construction workers from the same company participated in a cross-sectional study. Spirome...

Airflow limitation and changes in pulmonary function among bleachery workers.

This study investigated whether chronic airflow limitation and rapid decline in pulmonary function were associated with peak exposures to ozone and other irritant gases in pulp mills. Bleachery workers potentially exposed to irritant gassings (n = 178) from three Swedish pulp mills, and a comparison group of workers not exposed to irritant gassings (n = 54) from two paper mills, were studied. B...

Controlled trial of respiratory muscle training in chronic airflow limitation.

BACKGROUND Whether respiratory muscle training is of benefit to patients with chronic airflow limitation is controversial. The objective of the study was to determine the effect of resistance breathing training on physiological and functional measures in patients with chronic airflow obstruction. METHODS The design was a randomised, double blind, controlled trial with a six month follow up. E...

Reversible airflow limitation in adults with respiratory infection.

The aim of the study was to determine the occurrence of airflow limitation and the frequency of significant reversibility in respiratory infections in adults without known asthma or chronic obstructive pulmonary disease (COPD). We also wanted to study the association between airflow limitation and aetiological agents diagnosed by serological analyses. Spirometry was performed in 574 adult gener...
