The Authors have carried out an epidemiological longitudinal study on a group of 134 patients affected with occupational allergic contact dermatitis. The workers in question were grouped into production categories according to the classification criteria proposed by the Regione Emilia-Romagna for epidemiological studies. This subdivision has underlined the existence of similar conditions in the various groups as regards age, time of onset and legal-medical measures. After the first observation, made in a previous 5-years period, the patients were put through a follow-up which included a patch test and the evaluation of a series of parameters which were inserted in a questionnaire in order to examine their allergological-clinical situation after a period of time. The patch tests reconfirmed the previous positivity in 70.8% of the workers, while in 22.5% the positivity had increased. Finding an improvement in the result of the tests in 6.7% of the cases in a fact that, even though limited, is rather rare in Literature. Of course, several cases of polysensitization and crossed sensitization were found. The other parameters evaluated in this study (age, period of latency for the onset of the pathology, individual preventive means used, legal-medical measures) showed variable results in the single categories.
