BOHRF Original Authors' Main Conclusions
The original authors' main conclusions are taken from Abstract, Results and
Discussion. They are decided upon by the authors of the BOHRF occupational
asthma guidelines and form part of the guidelines.
Peak expiratory flow rate (PEFR) was recorded in workers with respiratory symptoms who were exposed to isocyanate fumes at work. Each worker was also admitted for bronchial provocation testing to toluene di-isocyanate (TDI) or diphenylmethane di-isocyanate (MDI) fumes or both. A final assessment of work-related asthma made from subsequent work exposure was compared with the results of bronchial provocation testing and a subjective assessment of peak flow records. Both techniques were specific and sensitive. Recovery from work-induced asthma was shown to be slow - up to seventy days. Several workers developed a pattern resembling fixed airways obstruction.
