Dermatological alterations in women working on dairy farm: a case study

The content of latex gloves therefore may cause different types of reaction to the employee using them, such as contact dermatitis caused by irritation, allergic dermatitis of contact due to the chemicals and contact urticaria (FERNANDEZ et al, 2009). Thus, despite latex gloves are an individual protective device at the workplace, they may cause changes in the dermatological integrity (OLIVEIRA & ALCHORNE, 2011), and, therefore deserve attention from the workers, managers and health professionals.…”

“…A wet working environment contributes to the iniciation of the disease. 6,7 The following aspects are important to make a precise diagnosisof OCD: 1) case history of occupational exposure to irritative or allergenic agents identified in the working environment; 2) concurrence of the beginning of the disease with the period of occupational exposure; 3) correlation among location of the lesions and contact areas with the main suspect agents; 4) improvement of the dermatosis with removal from the working environment and worsening with return to work and 5) a positive contact test also relevant with the case history and clinical condition of the patient. 3,7,8 The objectives of this work were: 1) to verify the frequency of OCD in patients examined in an ambulatory of skin allergies; 2) to evaluate the profile of patients according to age, sex, race, atopic antecedents, professional activity, evolution time and location of the dermatosis; 3) to verify the different types of contact dermatitis diagnosed; 4) to demonstrate which are the main sensitizing substances and 5) to compare the frequencies of the main sensitizers with the results obtained from patients treated in the same period of time, without suffering from OCD.…”
