Investigation of Occupational Dermatological Problem with Additives in Polypropylene Manufacturing Process: Seung Ho Jeon, Kyong Min Lee, Kan Woo Yoon, Do Myung Paek, Jong Yeop Yoo, Hee Chul Eun; Korean Journal of Occupational and Environmental Medicine 2003;15(3):252-260.

Abstract PDF: OBJECTIVES
To investigate the causative agents for the dermatological problems associated with the polypropylene manufacturing process.
METHODS
The study subjects consisted of 44 male workers involved in the polypropylene manufacturing process. Twenty-seven of them had been exposed to additives, and the remaining 17 had not. Among the 27 exposed, 10 had been exposed previously, and 17 are currently being exposed through their duties. Patch test were performed with three different concentrations, 0.1%, 1% and 10% of 10 different additives that was diluted with Vaseline.
RESULTS
18 subjects (41%) had positive reactions to the patch tests. Exposed group had a higher reaction rate (51.9%) than the control group (23.5%). When the positive reactions were further classified, 7, 6 and 5 were compatible with probably irritant, probably allergic, and multiple hypersensitivity reactions respectively. The most frequent reactions were from Ultranox-626 followed by Millad 3988, Armoslip-E and Songstab Sc-100.
CONCLUSIONS
When considering the significantly higher probability of an allergic reaction rate among the currently exposed group compared to non- or previously-exposed groups, the nature of dermatological problems in a polypropylene plant is probably allergic. Ultranox-626, Millad3988, Armoslip-E and Songstab Sc-100 were the main causatives agents found in the process.

Occupational Contact Dermatitis in Patch Test Clinics of General Hospitals: Hee Chul Eun, Bong Koo Lee, Kea Jeung Kim, Hyung Jai Kang; Korean Journal of Occupational and Environmental Medicine 1989;1(2):160-167. Published online November 30, 1989; DOI: https://doi.org/10.35371/kjoem.1989.1.2.160

Abstract PDF

Occupational allergic contact dermatitis cases who had visited the patch test clinics of Seoul National University Hospital(1984-1988) and Koryo General Hospital(1982-1988) were analyzed in this study. Patch test was performed with either Hollister-Stier standard battery or European standard battery in addition to the patients own materials and other commercially available antigens. Patch test was peformed according to the recommendation of International Contact Dermatitis Research Group. The result is summarized as follows. 1. Out of 946 cases 65 (6.9%) were suspected as having occupational dermatoses clinically and 35 (3.7%) were diagnosed as occupational allergic contact dermtitis after patch test. 2. Sixteen (45.7%) out of the 35 patients were male and 19 (54.3%) were female. Twenty one (60.0%) patients were in the age of 20 to 40 years. 3. The occupational distribution of 35 patients were medical personnels (8), cement workers (7), industrial workers (5), hair dressers (5), farmers (3), merchants (3), cooks (2) and painters (2). 4. Potassium dichromate, nickel sulfate and rubber chemicals were the most common occupational allergens. We also reviewed the Korean literatures related to the occupational dermatoses.
