Occupational asthma due to isocyanates.
162 subjects who had been exposed to isocyanates, who had developed symptoms during the exposure period, or in the evening or night and, therefore, had a history compatible with isocyanate-induced asthma, were studied with inhalation challenge testing to isocyanates (toluene diisocyanate and methylene diphenyl diisocyanate) and methacholine, because they were suspected of having occupational as...
متن کاملOccupational asthma caused by isocyanates: patterns of asthmatic reactions to increasing day-to-day doses.
Inhalation challenges to isocyanates are conducted in specialized centers to confirm occupational asthma. The pattern of asthmatic reactions due to consecutively increasing daily doses of isocyanates is unknown. We conducted a study involving 24 subjects who had undergone specific inhalation challenges to isocyanates (toluene diisocyanate [TDI], n = 8; hexamethylene diisocyanate [HDI], n = 10; ...

متن کاملOccupational asthma caused by natural rubber latex.
IgE-mediated sensitization in protein allergens of natural rubber latex (NRL) can induce immediate hypersensitivity reactions ranging from mild urticaria in life threatening anaphylaxis after cutaneous, mucosal or visceral exposure. Elutable allergens from NRL gloves absorb to the cornstarch powder particles, become airborne, and have the potential to cause respiratory reactions. Recent studies...
متن کاملOccupational asthma caused by heated triglycidyl isocyanurate.
Six workers exposed as bystanders to heated triglycidyl isocyanurate (TGIC) developed occupational asthma confirmed by serial peak expiratory flow measurement and Oasys analysis. Specific inhalation challenge testing resulted in late or dual asthmatic reactions to heated TGIC in four of four tested and was negative in three control asthmatics. One worker tested only with unheated TGIC had a neg...
