[Specific bronchostimulation tests in occupational medicine].

A review of the literature about specific bronchial provocation tests in occupational asthma was made. The Authors focus on some problems related to the methods of exposure; furthermore, in separate chapters the bissynosis and the relationship between specific and aspecific hyperresponsivity are dealt with. The Authors conclude that it is necessary a standardization of the methods for the reproducibility of the tests, and, as in aspecific hyperresponsivity, so also the specific responsivity may be quantified in dose-response curves.
