Evolution of occupational asthma: Does cessation of exposure really improve prognosis?
2014, Respiratory MedicineCitation Excerpt :In the present study we did not find a relation between any of the variables (once again including the type of agent or the avoidance or continuation of exposure) and a deterioration or improvement in FEV1. Chang Yeung et al. [32], studying 185 workers exposed to plicatic acid, found higher values for those who terminated exposure. Paradoxically, Moscato et al. [4] studying 25 patients exposed indistinctly to HMW or LMW agents found better values for subjects who remained exposed.
Occupational asthma: Review of assessment, treatment, and compensation
2011, ChestCitation Excerpt :Most data regarding occupational asthma have come as a result of studies focused on a specific industry or manufacturing process. For example, as many as 11% of spray painters exposed to diisocyanate-based paints have bronchial hyperreactivity,13 and roughly 5% of workers in the lumber industry exposed to western red cedar dust developed asthma.14 As many as 2.5% of all workers exposed to natural rubber latex15 and up to 20% of bakers or warehouse workers exposed to flour16 have been reported to have occupational asthma; farmers, painters, and cleaners have been reported to have the greatest risk for developing occupational asthma.17
