Abstract
PDF - OBJECTIVES
This study was carried out to estimate the magnitude of skin disease related to occupation and to find out the characteristics of it. METHODS: We collected and analyzed the cases of occupational skin disease reported by surveillance system composed of doctors and nurses in 150 enterprises with dispensary or attached hospital and physicians in 92 specific health examination institutes and 150 dermatologists from May to November, 1998. RESULTS: Among members of surveillance system, 66 enterprises and 47 specific health examination institutes and 55 dermatologists reported 571 cases of occupational skin disease in 512 workers. Excepting 81 cases reported by dermatologists, We analyzed 490 cases reported by enterprises and specific health examination institutes. Among 490 cases, contact dermatitis was most common(368 cases, 75.1%) and the second was hyper or hypopigmentation(36 cases, 7.3%). When we analyzed the characteristics of workers with occupational contact dermatitis, male workers were 281(79.2%) and female were 74(20.8%). 165 workers(64.5%) had chronic skin disease with repeated cure and relapse. 245 workers(72.5%) answered positively that their coworkers had similar skin disease. 27 workers(8.7%) experienced absence due to contact dermatitis related to occupation. To analyze the type of industries of workers with occupational contact dermatitis, automobile and trailer manufacturing industry was most common(105 cases, 29.6%) and the second was manufacturing industry for image, sound and communication equipment(55 cases, 15.5%). Organic solvent(183 cases, 46.7%) was the most common treating material of workers with contact dermatitis and the second was various kinds of chemicals(59cases, 15.1%). CONCLUSIONS: This is the first study using nationwide surveillance system to collect data of occupational skin disease. We found that many workers had skin disease related to occupation and characteristics of occupational skin disease were chronic and clustering. Therefore, we had to establish counterplan to manage occupational skin disease and to operate surveillance system to identify trends of occupational skin disease, continuously. -

- Painting is risky work to occupational skin disease. This research was carried out to investigate the prevalence of occupational skin disease in painting department of a shipyard company in June 1996. Dermatological examination, self-administered questionnaire survey, compositional analysis of solvents used in painting and cleaning were conducted. Exposed group(n=379) was selected randomly in painting department and control group(n=151) was selected in those who had not exposed to paints or solvents. Exposed group was divided into two groups by substance to contact ; painters contact to paints and organic solvents and workers contact to cleaners mainly composed of organic solvents. The prevalence of contact dermatitis(11.9%) is significantly elevated compared with control group(2.6%), and age adjusted odds ratio(OR) is 4.95 (95% confidence interval[CI]: 1.75-14.03). The prevalence of Tinea pedis, the most common skin disease, in exposure group is 48.0%, and its age-adjusted odds ratio(OR) is significantly elevated compared with control group (OR:3.17, 95% CI:2.06-4.88). Pompholyx is also significantly elevated in prevalence(11.9%) and age-adjusted OR(OR:6.69, 95% CI:2.05-21.87). There were no difference in the prevalence of contact dermatitis, Tinea pedis, and pompholyx by use of protector, work type, and duration of employment in painting department. In exposure group, 71.1% suffer from contact dermatitis improved in vacation or holiday and 68.9% of them had lesion in exposed area, it suggest that contact dermatitis in exposed group is related to their work. In conclusion, workers in painting department have high risks of contact dermatitis, Tinea pedis, and pompholyx. A health policy should be provided to prevent skin disease among painting department.

Abstract

- In an epidemiological study of metal workers exposed to metalworking fluids(MWF), the prevalence time of evoultion, seasonal occurrence and clinical type of contact dermatitis were investigated. Composinal analyses of MWF with HPLC, dermatological examination and two consecutive questionnaire surveys were conducted. Study population was divided into two groups ; workers contact to cutting oil and workers contact to rust preventive oil. In the analysis of MWF, aliphatic hydrocarbons, having 12-20 carbons, was most common composition(49.04%) of cutting oil otherwise, major contents (90.99%) of the rust preventives oil were aliphatic hydrocarbons composed of 6-9 carbons. The frequency (point prevalence) of contact dermatitis(CD) was 7(12.7 per 100 subjects) in the dermatological examination of 55 workers. As the result of second survey for contact dermatitis, cumulative prevalence of oil working full-time and recent 1 year prevalence in two groups were 28.0, 16.7 and 15.1, 12.5 per 100 subjects. There were no difference in the prevalence of CD by oil, age, oil contact duration. Summer is the most common evolution season in workers exposed to cuttiogs, but not in workers exposed to rust preventive oil. Major clinical type of CD was erythematous papules in both groups. It presents the importance of preventive measures that 51.1% suffer from contact dermatitis had medical care at their own expense, and 47.1% of them felt serious about their contact dermatitis. From the fact that 68.6% think cotton gloves protective apparatus, we emphasize the need for health education.

- We investigated the 1,004 workers who worked in a automobile factory to study the epidemiologic characterist of dermatoses due to cutting oils. Among the workers, 667(66.4%) answered the questionnaire. They are belong to 5 departments of the factory-the Engine-Work(86), Power train Assembly(17). We measured the oil mist concentration in air of the departments and examined the workers who had dermatologic symptoms. The results were follows; 1) Oil mist concentration; Of all measured points(52), 9 points(17.2%) exceeded 5mg/m3-the time-weighed PEL- and one department had a upper confidence limit(95%) higher than 5mg/m3. 2) Dermatologists examined 213 workers. 172 of them complained any skin symptoms at that time-itching(32.5%), papule(21.6%), scale(15.7%), vesicle(12.5%) in order. The abnormal skin site found by dermatologist were palm(29.3%), finger & nail(24.6%), forearm(16.2%), back of hand(8.4%) in order. 3) As the result of physical examination, we found that 160 workers had skin diseases. Contact dermatitis was the most common; 69 workers had contact dermatitis alone(43.1%), 11 had contact dermatitis with acne(6.9%), 10 had contact dermatitis with folliculitis(6.3%), 1 had contact dermatitis with acne & folliculitis, and 1 had contact dermatitis with abnormal pigmentation. Others were folliculitis(9 workers, 5.6%), acne(8, 5.0%), folliculitis & acne(2, 1.2%), keratosis(1, 0.6%), abnormal pigmentation(1, 0.6%), and non-specific hand eczema(47, 29.3%). 4) The prevalence of any skin diseases was 34.0 per 100 in cutting oil users, and 13.3 per 100 in non-users. Especially, the prevalence of contact dermatitis was 23.0 per 100 in cutting oil users and 4.3 per 100 in non-users. 5) We tried patch test(standard series, oil series, organic solvents) on 49 patients to differentiate allergic contact dermatitis from irritant contact dermatitis and found 20 were positive. 6) In a multivariate analysis(independent=age, tenure, kinds of cutting oil), the risk of skin diseases was higher in the water-based cutting oil user and both oil user than non-user or neat oil user(odds ratio were 2.16 and 2.78, respectively). And the risk of contact dermatitis was much higher at the same groups(odds ratio were 5.16 and 6.82, respectively).
