The Prevalence of Asbestos Exposure-induced Pleural Thickening on Chest Radiograph in Repairing Shipyard Workers: Byeong Jin Ye, Jung Il Kim, Hyun Jae Lee, Ki Nam Kim, Ki Nam Lee, Kap Yeol Jung, Joon Youn Kim, Sung Ho Yun; Korean Journal of Occupational and Environmental Medicine 2008;20(1):9-14. Published online March 31, 2008; DOI: https://doi.org/10.35371/kjoem.2008.20.1.9

OBJECTIVES
This study evaluated the prevalence of asbestos exposure-induced pleural thickening on chest radiograph in repairing shipyard workers.
METHODS
A total of 2,114 incumbent and retired workers in a shipyard underwent chest radiograph, questionnaire study, interview, and physical exam from 2005 to 2007. Finally, 1,702 workers were selected and classified into two groups according to asbestos exposure: exposure and non-exposure groups. The characteristics in the exposure group were investigated.
RESULTS
The prevalence of pleural thickening on chest radiograph was 5.2 % and 3.1 % in the exposure and non-exposure groups, respectively (p<0.05). In those aged 50 years or above, the prevalence was 17.6 % and 8.7 % in the exposure and non-exposure groups, respectively (p<0.05). The prevalence was 16.5 % and 30.2 % and the odds ratio was 2.34 (95% CI; 1.15-4.77) and 2.95 (95%CI; 1.08-8.07) in the workers with an exposure duration of 20-29 years and more than 30 years, respectively. The prevalence was higher when considering tuberculosis history.
CONCLUSIONS
The prevalence was increased with increasing exposure duration was more than 20 years. The authors therefore suggest that this group should be followed up periodically by special program and that a longitudinal study with repairing shipyard workers as the cohort should be undertaken.

Mercury Concentrations of Maternal and Umbilical Cord Blood in Korean Pregnant Women: Preliminary Study: Kyung Eun Lee, Young Seoub Hong, Dae Seon Kim, Myoung Seok Han, Byeng Chul Yu, Young Wook Kim, Mee Sook Roh, Hyun Jae Lee, Jae Won Lee, Jong Young Kwak, Joon Youn Kim; Korean Journal of Occupational and Environmental Medicine 2007;19(4):268-275. Published online December 31, 2007; DOI: https://doi.org/10.35371/kjoem.2007.19.4.268

Abstract PDF

OBJECTIVES
To evaluate the level of maternal and prenatal mercury exposure and to analyze the related factors.
METHODS
Fifty-nine pregnant women were recruited into this study after obtaining informed consent. Samples were collected at delivery from normal pregnant women who were living in the city of Busan, Korea. Mercury concentrations in maternal and umbilical cord blood samples were measured using a gold-amalgam collection method. The total and methyl mercury levels of 36 of the 59 pregnant women were analyzed after randomization, and the results were compared.
RESULTS
The mean total mercury concentration was 3.16+/-1.21 ppb and 5.43+/-2.22 ppb in maternal and cord blood, respectively. The average, maternal blood mercury level was lower than the prescribed toxic limit for human (WHO, 5 ppb), whereas the cord blood mercury was higher. The mercury exposure level exceeded the WHO recommendation in 5 (8.47%) cases of maternal blood and 29 of (49.15%) cord blood. There was a significant correlation between maternal and cord blood mercury concentrations. Total mercury and methyl mercury concentrations of the 36 random pregnant women were 3.06+/-1.17 ppb, and 2.60+/-1.11 ppb in maternal blood, and 5.20+/-2.36 ppb, and 4.70+/-1.97 ppb in cord blood, respectively. Methyl mercury accounted for 85.0% of the total mercury in maternal blood and 90.4% in cord blood. There was a significant correlation between total and methyl mercury concentrations.
CONCLUSIONS
The study results suggest that mercury concentrations of cord blood may be regarded as indicative of high prenatal mercury exposure. Therefore, further studies are necessary to explain the cause of high mercury concentrations in cord blood, and to examine its relationship with various health indices.

Usefulness of High Resolution Computed Tomography (HRCT) in the Diagnosis of Asbestos-Related Lung Diseases: Hyun Jae Lee, Ji Eun Son, Young Seoub Hong, Young Ill Lee, Byung Jin Yeah, Chang Hun You, Kap Yeol Jung, Sang Hoon Kim, Hyoung June Im, Eun Chul Jang, Jung Man Kim, Joon Youn Kim; Korean Journal of Occupational and Environmental Medicine 2006;18(2):112-122. Published online June 30, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.2.112

Abstract PDF

OBJECTIVES
This study was carried out to improve the medical surveillance program of workers exposed to asbestos by examining the usefulness of High Resolution Computed Tomography (HRCT) in the diagnosis of asbestos-related lung disease.
METHODS
The study subjects comprised 162 workers in a ship-repairing yard, 68 of whom had been directly exposed to asbestos and 94 indirectly exposed. The 'Occupational Safety & Health Administration (OSHA) asbestos standard, medical surveillance program' and HRCT were conducted to analyze the aspects of the asbestos-related lung disease. The OSHA asbestos standard, medical surveillance program consists of simple chest x-ray, spirometry and medical questionnaire.
RESULTS
Seventeen (10.5%) of the 162 subjects, 10 (14.7%) directly exposed and 7 (7.4%) indirectly exposed, revealed asbestos-related lung disease on HRCT. The sensitivity and specificity of simple chest x-ray for asbestos-related lung disease were 70.6% and 98.6%, and the positive and negative predictive values were 85.7% and 96.6% respectively, as compared with HRCT. HRCT was an effective diagnostic tool especially to detect early asbestos-related lung disease. The study results indicated a relative significant association between the results of spirometry and HRCT. The variables significantly associated with asbestos-related lung disease on HRCT were work duration, smoking history (pack-years), past history of respiratory disease, cough and dyspnea.
CONCLUSIONS
In the diagnosis of asbestos-related lung disease, HRCT should be considered not only for workers with positive findings on simple chest x-ray, but also workers with specific findings on spirometry, occupational history, smoking history, and past history of respiratory disease, or with respiratory symptoms such as cough and dyspnea.

Published online March 31, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.1.53

Abstract PDF

OBJECTIVES
The objectives of this study were to estimate the proportion of occupational lung cancer in the Busan area.
METHODS
Occupational physicians of four university hospitals operating an occupational disease surveillance system in the Busan area actively interviewed all of the newly diagnosed, lung cancer cases about their characteristics and occupational histories through a survey questionnaire and chart review. To evaluate and agree on the work-relativity, the cases were presented in periodic meetings.
RESULTS
A total of 301 lung cancer cases were interviewed, of which 50 (16.6%, all male, 27 probable and 23 possible) were related to occupational exposure. The exposure materials were asbestos, Cr, PAH etc. Pathologic findings included squamous cell carcinoma, adenocarcinoma and small cell carcinoma.
CONCLUSIONS
The proportion of occupational lung cancer cases above the probable level was 9% and above the possible level was 17%. To develop the public health policy and to prevent further cancer death, the meaningful data from occupational cancer surveillance systems should be collected continuously for ongoing monitoring.

Factors Affecting Fatigue and Stress in Male Manufacturing Workers: Jin Wook Kang, Young Seoub Hong, Hyun Jae Lee, Byung Jin Yeah, Jung Il Kim, Jung Man Kim, Kap Yeol Jung, Joon Youn Kim; Korean Journal of Occupational and Environmental Medicine 2005;17(2):129-137. Published online June 30, 2005; DOI: https://doi.org/10.35371/kjoem.2005.17.2.129

Abstract PDF

OBJECTIVES
The aims of this study were to investigate the factors affecting the fatigue and stress in male manufacturing workers.
METHODS
A questionnaire investigating general characteristics, lifestyle factors, job characteristics, fatigue and stress was distributed to 896 subjects. From 851 respondents, 11 responses with insufficient data were excluded. The data were analyzed to investigate the factors affecting personal fatigue and stress.
RESULTS
Among the general characteristics, both fatigue and stress in the older group were significantly lower than in the younger group (p<0.05). Fatigue in the group with higher education was significantly higher than in the group with only high school education (p<0.05). The group who lived alone had significantly more stress (p<0.05). Among lifestyle factors, people who exercised regularly had significantly lower fatigue and stress than those who did not (p<0.05). Fatigue was negatively correlated with decision latitude, supervisor support, and coworker support. Stress was positively correlated with job demand and negatively correlated with decision latitude, supervisor support, and coworker support. Fatigue and stress were positively correlated with each other. Multiple linear regression analysis showed that among job characteristic factors, coworker support affected fatigue while job demand and supervisor support affected stress.
CONCLUSIONS
Fatigue and stress were positively correlated, but the job characteristics that affected each were different. This suggests that for effective management of fatigue and stress, the details of job characteristics need to be considered individually for the intervention and prevention of fatigue and stress.

A Case of Lung Cancer Caused by Long-Term Asbestos Exposure: Dong Young Yoon, Jin Wook Kang, Hyun Jae Lee, Jung Il Kim, Ji Eun Son, Kap Yeol Jung, Joon Youn Kim, Mee Sook Roh; Korean Journal of Occupational and Environmental Medicine 2004;16(4):499-507. Published online December 31, 2004; DOI: https://doi.org/10.35371/kjoem.2004.16.4.499

Abstract PDF

OBJECTIVES
To report a case of lung cancer caused by long-term asbestos exposure in a shipyard.
METHODS
We evaluated chest X-ray, pulmonary function test, and chest CT and analyzed asbestos concentration in the lung tissue and bulk sample from the workplace. We also performed a workplace survey.
RESULTS
The patient had worked at the shipyard for 31 years. The biopsy samples were processed to determine the asbestos content in the lung tissue and bulk sample using a transmission electron microscope (TEM) equipped with an energy dispersive X-ray analyzer (EDX). The TEM-EDX analysis revealed many asbestos fibers, the majority of which were amosite. In addition, the concentration asbestos fibers in the workplace exceeded the occupational exposure limits of asbestos.
CONCLUSIONS
Our findings strongly suggest that this patient's lung cancer was related to the long-term asbestos exposure.
