Occupational asthma and rhinitis due to Western red cedar (Thuja plicata), with special reference to bronchial reactivity.
Gandevia, B., and Milne, J. (1970). Brit. J. industr. Med., 27, 235-244. Occupational asthma and rhinitis due to Western red cedar (Thuja plicata), with special reference to bronchial reactivity. With the increasing use of Western, or Canadian, red cedar (Thuja plicata) in the timber industry, a distinctive respiratory syndrome of rhinitis and asthma has been observed with increasing frequency ...
متن کاملDistribution of DRB1 and DQB1 HLA class II alleles in occupational asthma due to western red cedar.
Occupational asthma caused by western red cedar is a common problem in sawmill industries. The objective of this study was to examine a possible association of human leukocyte antigen (HLA) class II genetic markers with susceptibility or resistance to western red cedar induced asthma. The distribution of DRB1 and DQB1 HLA class II alleles and DRB1-DQB1 haplotypes was studied in 56 Caucasian pat...
متن کاملLung function decline in asthma.
P rogressive decline in lung function in asthma has been well recognised but not fully explained. For example, in a Danish population study (the Copenhagen City Heart Study), three measurements of forced expiratory volume in one second (FEV1) were made over 15 yrs in 17,506 subjects, including 1,095 with asthma [1]. Asthmatics showed a decline in FEV1 of 38 mL?yr compared with 22 mL?yr in norma...
متن کاملAssociation of occupational pesticide exposure with accelerated longitudinal decline in lung function.
Cross-sectional studies have shown that occupational exposure to vapors, gases, dusts, and fumes (VGDF) and pesticides is associated with a lower level of lung function. These associations seem to be stronger in ever smokers. In the current study, we aimed to assess whether occupational exposure to VGDF and pesticides is associated with longitudinal decline in lung function. We used 12,772 obse...
متن کاملLung function decline in bronchial asthma.
STUDY OBJECTIVE We evaluated the longitudinal changes in lung function and the factors associated with FEV(1) changes over time in a sample of asthmatic subjects. SETTING FEV(1) measures were recorded every 3 months over a 5-year follow-up period. To compare all subjects independently of body size, FEV(1) values were normalized for the subject's height at the third power. We evaluated the pos...
