1.The percentage of Dematology Affedtion caused by Carreas in some Factories and Enterprices in Ha Noi
Journal of Practical Medicine 2004;484(8):23-27
From January 1999 to December 1999, after the dematology check on 4372 patients in 4 factories and enterprices in Ha Noi: the Hanoi Paint Factory, the Sao Vang Rubber Factory, Van Dien Battery Factory and Hanoi Weaving Factory showed that: The percentage of dematology associated with ocupation was 11.39%, the highest percentage is in the Hanoi Paint Factory: 20.39%, the lowest is in the Sao Vang Rubber Factory 4.99%. The most common regions are open regions (on the face: 19.77 - 45.33%); on the limbs: 16.00% - 36.97%; on the hands: 18.49% - 27.76%. The most common work experience: from 11 to 25 years, 98% of the patients have allergy.

OBJECTIVES: We tried to establish a Regional Occupational Surveillance System (ROSS) for estimating the prevalence and monitoring the trend of occupational dermatitis among 718 manufacturing workers exposed to organic solvents and nonmetallic chemicals in small and medium sized businesses of 1,2 industrial complex area of taejon City. METHODS: Through the report from the nurses of Group Occupational Health Management System, we made a case referral and immediate health examination system with occupational medical clinics. We also performed a survey for detecting occupational dermatitis by a self-administered questionnaire. Case must meet 3 criteria; 1) He/She must have one or more significant cutaneous signs and symptoms. 2) The symptom should be changed by the work condition or caused by risk chemicals. 3) Dermatitis should be diagnosed by a doctor. Results Among the 131 workers(17. 7 %) with significant symptoms screened by the questionnaire, 4 workers(0. 6 %) met the case definition criteria. And among the 45 workers (6. 3 9o) referred to the immediate diagnosed system, 14 workers (l. 9 %) were Strongly suspected to have occupational dermatitis. CONCLUSIONS: These prevalence rates were quite underestimated because of deficient recognition of the disease severity among the workers, reversibility of the target diseases, and life-threathening mood due to nationwide economic crisis and the socioeconomic withdrawal of each business. Ultimately, harmonized activities of government, industry, labor unions, volunteer organization and academy relating to occupational health in a community should be encouraged to do creative, consistent efforts for evolution and development of this first trial of ROSS.

Produced in large-scale since the 1950s, epoxy resins have been used diversely, and new uses are continuing to be found and developed so that the accompanying risks of dermatitis have been spread to new industries such as construction and road building. Epoxy resin, irritants and allergens, cause both direct and airborne contact dermatitis, and occupational dermatitis, This was observed shortly after they were introduced. We report a case of airborne allergic contact dermatitis by an epoxy resin in an antiskid-surfacing worker. A 46-year-old Korean male presented with symmetrical eczematous lesions on exposed areas. A Patch test revealed positive reactions to epoxy resin 1% and their own material, and the symptoms cleared when he changed work environments.

7.Two Cases of Cement Burn.

Annals of Dermatology 2000;12(3):197-198
Wet cement can cause caustic ulcers due to its alkalinity. Besides caustic ulcers frequently called cement burn, allergic and irritant contact dermatitides are common in cement workers. Alkalinity of calcium hydroxide in wet cement combined with the effect of pressure and occlusion against skin may result in cement burn. We report two cases of cement burn due to their occupational exposures.

8.Wet-work Exposure: A Main Risk Factor for Occupational Hand Dermatitis.
Safety and Health at Work 2014;5(4):175-180
Wet-work can be defined as activities where workers have to immerse their hands in liquids for >2 hours per shift, or wear waterproof (occlusive) gloves for a corresponding amount of time, or wash their hands >20 times per shift. This review considers the recent literature on wet-work exposure, and examines wet-work as a main risk factor for developing irritant contact dermatitis of the hands. The aim of this paper is to provide a detailed description of wet-work exposure among specific occupational groups who extensively deal with water and other liquids in their occupations. Furthermore, it highlights the extent and importance of the subsequent adverse health effects caused by exposure to wet-work.

OBJECTIVES: This study investigated occupational contact dermatitis in a tire factory, prompted by a long history of complaints of skin ailments by the factory workers. METHODS: Participants (n=160) completed a questionnaire concerning job characteristics and skin symptoms, and received a medical examination. Fifty-four workers with suspected work-related contact dermatitis were chosen for a patch test of contact-related dermatitis. RESULTS: The most frequent positive reactions of patch test were produced by diphenylguanidine, formaldehyde and cobalt. Twenty-one of the 54 individuals (38.9%) were judged to have work-related skin disease. CONCLUSIONS: Exposure to natural and synthetic rubbers and additive materials pose a risk of contact dermatitis in a tire manufacturing environment. Improved sanitary work practices and public health awareness measures are suggested.

Cement is increasingly used in the construction industry. Cement handling has been found to be responsible for many cases of occupational dermatitis, but cement burns have rarely been reported. Alkalinity of wet cement, abrasion by sand particulates, and prolonged contact, due to wet clothes, are relevant factors for cement burns. Although cement burns can result in full thickness burn and severe sequelae, the prevalence and severity are underestimated, due to the unawareness of patients and physicians. Herein, we report two cases of cement burns in construction workers, who had contacted with wet cement on lower extremities from their occupational exposures.
