two to nine hours and reached maximum intensities after between six and 20 hours of the start of exposure. In one subject with farmer's lung, symptoms began after about one hour, while in two avian reactors the onset of symptoms was delayed for 12-18 hours after the start of exposure. With both ...

Comments for the paper: "Rat-specific IgG and IgG4 antibodies associated with inhibition of IgE–allergen complex binding in laboratory animal workers", 2014, Occup Environ Med

Comments for the paper: "A cluster of lung injury cases associated with home humidifier use: an epidemiological investigation", 2014, Thorax
An outbreak os rapidly progressive respiratory disease in children and adults has been caused by biocides/detergents used in home humidifiers. Most were attributed to polyhexamethyleneguanidine. Removal of the detergent/biocide from humidifiers stopped the outbreak. Prgnant women were particular ...

Comments for the paper: "Occupational irritants and asthma: an Estonian cross-sectional study of 34 000 adults.", 2014, Eur Respir J
This is a difficult study to interpret aas the prevalance of asthma is probably underestimated and the exposures not related to the date of onset of the asthma. Never-the-less exposure to low level occupational irritants such as combustion products and environmental tobacco smoke had a higher po ...

Comments for the paper: "Work-exacerbated asthma in a workers’ compensation population", 2014, Occup Med (Oxford)
Work-exacerbated asthma as defined required pre-existing asthma in nearly all, no evidence of sensitasion, generally a history of worsening asthma with work exposure, and if specific challenges were done they had to be negative. Symptoms had to persist for >4 weeks. All had to have asthma confir ...
