Occupational diseases due to cooling fluids.

Contact dermatitis to cutting fluids is a very frequent cause of occupational skin disease, with different mechanisms for those caused by irritation or allergies. The different allergens in question are many and complex. Different batteries of patch tests are available but the interpretation of the relevance of positive tests is not simple. The aim of this work is to make clearer the investigative methods and the interpretation of the relevance of the results of patch tests, for more effective prevention.
