Occupational dermatoses in oil refining

Prikazani su rezultati istraživanja o djelovanju nafte i njenih derivata na kožu 736 radnika u rafineriji nafte i 335 radnika u jednom transportnom poduzeću. Znatan broj utvrđenih profesionalnih dermatoza karakterističan je za djelovanje naftnih produkata, a jedan dio je rezultat djelovanja raznih kemikalija koje se upotrebljavaju u toku prerade nafte. Promjene u smislu profesionalnih dermatoza nađene su kod 31,1% radnika u rafineriji nafte i kod 15,8% radnika u kontrolnoj grupi. Najčešći nalaz bile su akneiformne promjene, kao i grupa banalnih promjena (atrofije, fisure, ulceracije itd.). Učešće alergijskih profesionalnih dermatoza u ukupnom broju profesionalnih kožnih promjena bilo je vrlo malo. Testiranjem statističke značajnosti razlika, utvrđen je značajno veći broj profesionalnih dermatoza kod radnika u rafineriji nafte nego u kontrolnoj grupi, a to pokazuje da su nafta i njeni derivati jedan od glavnih uzroka za tako veliki broj profesionalnih dermatoza kod radnika koji rade na preradi nafte.The results are presented of the investigations into the effect of oil and its products on the skin of 736 workers in an oil refinery and 335 workers in a transport enterprise. A considerable number of evidenced occupational dermatoses proved characteristic of the effect of oil products on the skin while a minor part proved to have resulted from the effect of various chemicals used in oil refining processes. Changes characteristic of occupational dermatoses were observed in 31.1 percent of oil refining workers and in 15.8 percent of the control group. The most frequent findings were acneiform changes, as well as such common changes as atrophies, fissures, ulcerations, etc. The occurrence of allergic occupational dermatoses in relation to the total number of occupational skin\u27 changes was insignificant. The difference between a considerably higher number of occupational dermatoses in oil refining workers and the number of occupational dermatoses in the control group has proved statistically significant. This indicates that this comparatively high occurrence of occupational dermatoses in oil refining workers is for the most part due to the effect of oil and its products
