Effect Assessment of Worksite-based, Post-examination, Health Care Management System: Kang Jin Lee, Young Hee Choi, Cha Jae Oh, Hoo Rak Lee, Hyoung June Im, Moon Young Hwang, Byung Mann Cho, Ji Ho Lee; Korean Journal of Occupational and Environmental Medicine 2006;18(1):1-14. Published online March 31, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.1.1

OBJECTIVES
This study was conducted to develop a worksite-based, post-examination, health care management system for continuous and systematic management of workers with hypertension, diabetes mellitus, hyperlipidemia, and abnormal LFT detected by periodic health examination and to assess the effectiveness such a system as an intervention study.
METHODS
Study subjects were selected from workers with hypertension, diabetes mellitus, hyperlipidemia, and abnormal LFT according to the selection criteria. The intervention group, but not the control group, received medical treatment of disease, follow up examination, and health education which consisted of information about the disease and the importance of life-style modification through periodic interview using the resources of occupational health service center in the worksite. To assess the effectiveness of this system, we compared follow up examination data from the intervention group with periodic examination data from the worksite control group.
RESULTS
In the intervention group a significant reduction trend was recorded for systolic and diastolic blood pressure, fasting blood sugar, postprandial 2 hour glucose, total cholesterol, triglyceride, LDL-cholesterol, AST, ALT, and gamma-GTP, and a rising trend for HDL-cholesterol. Significant group differences ware recorded for fasting blood sugar, postprandial 2 hour glucose, total cholesterol, AST, and ALT.
CONCLUSIONS
The worksite-based, post-examination, health care management system was effective for the continuous and systematic management of workers who had abnormal findings detected by periodic health examination.

Evaluation of Ototoxicity by Mixed Organic Solvents Using the Upper Limit of Hearing: Ji Ho Lee, Cheol In Yoo, Choong Ryeol Lee, Hun Lee, Young Hee Choi, Nam Jung Kim, Yangho Kim; Korean Journal of Occupational and Environmental Medicine 2004;16(4):391-400. Published online December 31, 2004; DOI: https://doi.org/10.35371/kjoem.2004.16.4.391

Abstract PDF: OBJECTIVES
This study evaluated the ototoxicity by mixed organic solvents on workers'hearing using the upper limit of hearing(ULH).
METHODS
Seven hundred ninety-seven male workers in the ship building industry who were evaluated by interview with an upper limit of hearing from August 2000 to July 2002 were enrolled in the study. The subjects were divided into 3 groups according to exposure profile and job: officers, field supporters, and painters. To assess the ototoxicity of mixed organic solvent exposure on hearing, with regard to confounders, the general liner model was used.
RESULTS
After controlling for the possible confounders, such as age, career, noise exposure level, tinnitus, alcohol intake, and smoking, the estimated mean for ULH of the painter group was higher than that of the officer and the field supporter groups. These differences of mean ULH were at the borderline of statistically significance(p=0.069).
CONCLUSIONS
The results of this study suggest that a relatively lower level of mixed organic solvent chronically affected the hearing organ or auditory pathway. ULH seems to be a useful method for early detection of the ototoxicity of organic solvents.

Epidemiologic Characteristics of Hand-Arm Vibration Syndrome through Occupational Disease Surveillance System in Busan, Ulsan, Kyungnam Province: Young hee Choi, Cheol In Yoo, Ji Ho Lee, Choong Ryeol Lee, Hun Lee, Young Wook Kim, Chang Ho Chae, Sang Baek Koh, Euna Kim, Lu Jin Lee, Yang ho Kim; Korean Journal of Occupational and Environmental Medicine 2003;15(3):261-268. Published online September 30, 2003; DOI: https://doi.org/10.35371/kjoem.2003.15.3.261

Abstract PDF: OBJECTIVES
The objectives of this study were to estimate the epidemiologic characteristics of hand-arm vibration syndrome (HAVS) due to occupational exposure of hand transmitted vibration and to identify the occupations and industries where such exposures arises, and the main sources of exposure.
METHODS
In April 2001 the Busan, Ulsan, and Kyung-Nam Province occupational disease surveillance system was established to measure the incidence and prevalence of work-related HAVS and other occupational diseases in these Korean provinces. Occupational physicians of nine hospitals in Busan, Ulsan, and Kyung-nam Province were involved in this project between April 2001 and November 2002. Physicians collected information through questionnaires and interviews. Information gathered included age, occupation, types of vibration tools used and presence of subjective symptoms such as vibration-induced white finger (VWF), numbness and tingling.
RESULTS
A total 192 cases were reported with 188 males and 4 females. The shipbuilding industry was the most common type of industry and grinders were the most common source of exposure. Symptoms of neurological disorder were more common than those of vascular disorder.
CONCLUSIONS
The authors concluded that exposure to hand transmitted vibration is common and that HAVS is one of the most common occupational diseases in Korea. However, the range and extent of hand transmitted vibration and the overall prevalence of HAVS in Korea is still unknown. More extensive research on this syndrome in order to priorite necessary preventive measures is required.

Evaluation of Finger Skin Temperature by Cold Provocation Test for Diagnosis of Hand-Arm Vibration Syndrome: Cheol In Yoo, Ji Ho Lee, Choong Ryeol Lee, Hun Lee, Young Hee Choi, Yang Ho Kim; Korean Journal of Occupational and Environmental Medicine 2002;14(2):124-133. Published online June 30, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.2.124

Abstract PDF

OBJECTIVES
Various objective tests have been widely used worldwide for diagnosing the hand-arm vibration syndrome. Among these, the cold provocation test has been frequently used to confirm the presence of Raynaud's phenomenon. This study was carried out in order to evaluate finger skin temperature by cold provocation test(10 degrees C for 10 minute) for the diagnosis of hand-arm vibration syndrome METHODS: Fifty-eight workers who had been exposed to local vibration were examined. Information concerning age, occupation, types of vibration tools used, presence of subjective symptoms such as vibration induced white finger(VWF), and numbness and tingling were collected. The subjects were classified into three groups according to their symptoms(Vascular, Neural, and No symptom group). In order to examine the applicability of the cold provocation test using water at 10 degrees C for 10 minute, we compared finger skin temperature between the groups.
RESULTS
The mean value of the finger skin temperature at 5 minutes and 10 minutes after cold provocation as well as the recovery rate in the vascular group were significantly lower than that seen in the other groups.
CONCLUSIONS
The evaluation of finger skin temperature by cold provocation test is very useful method for the diagnosis of hand-arm vibration syndrome. The test results will assist in confirming the diagnosis of the hand-arm vibration syndrome.
