A Case of Primary Osteoarthritis of Both Elbow Joints in a Worker Using Sledge-hammers: Kyeong Yeon Kim, Kyung Han Kim, Jung Wan Koo, Yong Kyu Kim; Korean Journal of Occupational and Environmental Medicine 2010;22(1):77-84. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.77

Abstract PDF: BACKGROUND
The incidence of primary osteoarthritis of elbow is very low in individuals without work-related risk factors, and primary osteoarthritis of the elbow is rarely symptomatic. Because it is difficult to prove these conditions are work-related, the patients with work-related elbow osteoarthritis don't tend to be compensated in Korea.
CASE
REPORT: The patient was a 51-year old male, with an occupational history as a sledgehammer user for 23 years. He has been complaining of pain for 3 years. Physical examination of the elbow showed painful end-range motion and the radiographs showed osteophytes and, loose bodies, but relatively-preserved joint spaces, which were typical characteristic of primary osteoarthritis.
CONCLUSION
The authors report on a case of primary osteoarthritis of both elbows that was associated with repetitive high shear force due to long-term use of the sledgehammer.

A Case Study on the Effect of Chelation Therapy with Dimercaptosuccinic Acid (DMSA) for Lead Poisoning in an Adult: Yong Jin Lee; Korean Journal of Occupational and Environmental Medicine 2010;22(1):69-76. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.69

OBJECTIVES
We wanted to investigate the efficacy of dimercaptosuccinic acid (DMSA) for the treatment of lead poisoning in an adult.
METHODS
The chelation therapy was applied using oral DMSA after measuring the blood lead and performing, renal function tests, liver tests and a physical examination. This therapy with oral DMSA 30 mg/kg/day was administered three times a day for 5 days to an adult patient with a pre-chelation blood lead concentration of 75 microgram/dL. Testing was performed by assessing the daily blood lead level, the blood ZPP, the urine ALA, the symptoms and side effects were assessed by conducting a physical examination.
RESULTS
DMSA therapy given for the duration of 5 days reduced the blood lead concentration from 75 microgram/dL to 21.8 microgram/dL. The blood ZPP concentration fell from 366 microgram/dL to 300 microgram/dL. The urine ALA concentration fell from 9.71 mg/L to 0.38 mg/L. In addition, the symptoms of headache, dizziness and abdominal pain that were induced by lead were improved after 2 days of chelation therapy. The vomiting did not improve after 5 days of chelation therapy, but this resolved 14 days following cessation of therapy. No adverse effects of DMSA therapy were seen.
CONCLUSIONS
Oral chelation therapy with DMSA 30 mg/kg/day is possible without being admitted to a hospital and it is generally effective, safe, and relatively inexpensive. DMSA provides a positive effect on adult patients who have lead poisoning.

A Case of Bronchiolitis Obliterans after Exposure to Nitrogen Dioxide: Su Yeon Cheon, Yu Jin Kim, Sun Young Kyung, Sang Pyo Lee, Jeong Woong Park, Sung Hwan Jeong; Korean Journal of Occupational and Environmental Medicine 2010;22(1):64-68. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.64

Abstract PDF

INTRODUCTION: Irritant gases and aerosols are capable of inducing acute, irritant lung injury. Lung injury caused by the inhaling nitrogen dioxide (NO2) has been known as silo-filler's disease in western countries. In Korea, acute pulmonary edema after NO2 inhalation in an industrial environment has been reported. We report here on a case of bronchiolitis obliterans after inhalation of NO2.
CASE
REPORT: A 54-year-old male was admitted to the hospital with dyspnea and fever. Three weeks perviously, he was diagnosed with acute pulmonary edema after occupational exposure of NO2 and he was treated with corticosteroid for 2 weeks. After cessation of the corticosteroid, he developed dyspnea and fever. High resolution computed tomography (HRCT) showed ill-defined centrilobular nodules and patterns of mosaic perfusion; this all suggested air-trapping due to bronchiolitis obliterans. We diagnosed the patient as having bronchiolitis obliterans after acute pulmonary edema due to NO2 inhalation. The corticosteroid treatment was restarted and continued for 8 weeks.
CONCLUSION
NO2 induced lung injuries have variable clinical features. Close observation is needed for 6 to 8 weeks because recurrence with bronchiolitis obliterans may be seen several weeks later.

A Case of Silicosis and Pneumothorax in a Workplace Producing Dental Porcerlain: Youngjoong Kang, Won Jun Choi, Sang Yun Lee, Jong Wan Yun, Hyung Sik Kim, Jong Uk Won, Sang Hwan Han; Korean Journal of Occupational and Environmental Medicine 2010;22(1):58-63. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.58

Abstract PDF: BACKGROUND
Silicosis is more likely to occur in people working in the mining industry. However, workers suffering from silicosis have recently been reported frequently in other areas. We present a case of silicosis occuring in a 43-year-old man who had worked for 20 years in a workplace producing dental porcelain.
CASE
The man was admitted to the emergency room with acute chest pain caused by pneumothorax. Chest X-ray indicated numerous small opacities spread over the whole lung field and a large opacity in the right middle lung field. According to ILO classification, the shape of the small opacities was t/s, the profusion rate was 2/3 and the large opacity was classified into the B category. Following this diagnosis of silicosis, the patient's medical history and work exposure history were examined. According to his medical history, he had undergone closed thoracostomy in 2006 because he had suffered pneumothorax twice (in 2005 and 2006) and his smoking history was 7 pack years. In particular, he had been exposed to silica dust for 20 years in his workplace.
CONCLUSION
Despite the absence of any specific risk factor that caused pneumothorax, the patient suffered this condition three times. All clinical results and the progress of his physical symptoms, including radiologic findings from chest X-ray and computed tomography, clearly supported the diagnosis of silicosis. Except for exposure to silica dust in the workplace, no other risk factors causing silicosis were found. Therefore, he was finally diagnosed as having silicosis caused by exposure to silica dust in the workplace and followed by pneumothorax.

Analysis of the Influence of Job Stress and Psychosocial Factors on Self Perceived Fatigue in White Collar Male Workers Using the Structural Equation Model: Seung Pil Park, Dong Bae Lee, In Sun Kwon, Young Chae Cho; Korean Journal of Occupational and Environmental Medicine 2010;22(1):48-57. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.48

Abstract PDF

OBJECTIVES
This study was performed to determine the self-perceived fatigue and its association with job stress and psychosocial factors among white collar male workers.
METHODS
The self-administered questionnaires were given to 872 workers employed in 42 work places located in Daejeon City and Chungnam Province during the period from February 1st to April 30th, 2009. The questionnaire surveys included socio-demographic characteristics, job-related characteristics, health-related behaviors, a Job Content Questionnaire (JCQ), psychosocial factors (type A behavior pattern, locus of control, self-esteem) and the Multidimensional Fatigue Scale (MFS).
RESULTS
Concerning the correlation of self-perceived fatigue with various factors, while the level of self-perceived fatigue was positively correlated with the job demands, a type A behavior pattern and self-esteem, it was negatively correlated with job autonomy and supervisor support. With the analysis of the covariance structure, JCQ (job demand, job autonomy, supervisor support and coworker support) had more of an influence on the level of self-perceived fatigue than the psychosocial factors (type A behavior pattern, locus of control, self-esteem). The inter-relational effects were that the higher the JCQ and psychosocial factors, the higher the level of self-perceived fatigue.
CONCLUSIONS
The study results indicated that the level of self-perceived fatigue was more influenced by the JCQ than the psychosocial factors. Thus, an effective strategy for fatigue reduction among workers requires additional programs that will focus on innovated job specifications and managed psychosocial factors.

Job Stress as a Risk Factor for Occupational Injuries Among Employees of Small and Medium-sized Companies: Dal Young Jung, Jong Uk Won, Shin Goo Park, Sei Jin Chang, Hwan Cheol Kim; Korean Journal of Occupational and Environmental Medicine 2010;22(1):37-47. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.37

Abstract PDF

OBJECTIVES
This study was conducted to investigate the association between job stress and occupational injury among Korean employees.
METHODS
The data was obtained from a work-stress survey that was administered to employees of small and medium-sized companies in Incheon, Korea. A four-month prospective follow-up study was conducted (the baseline study was conducted from September 2006 to October 2006, and the follow-up study was done from March 2007 to April 2007). A total of 1,241 participants (774 males and 467 females) were included in the analysis. A structured self-reported questionnaire was used to assess each respondent's sociodemographics, work related factors, job stress, and occupational injury. Job stress was measured using 24 items (7 sub-scales) of the Short Form of the Korean Occupational Stress Scale (KOSS-SF). Occupational injuries were assessed by self-report during the follow-up period. We estimated the relation of job stress to occupational injury using logistic regression analyses.
RESULTS
A total of 199 employees (16.0%) had suffered at least one occupational injury during the previous 4-months. After adjustment for confounding variables, the logistic regression analyses indicated that the groups with high stress as related to 'Job demand' (OR=2.23, 95% CI=1.61-3.08), 'Organizational system' (OR=1.63, 95% CI=1.19-2.23), 'Lack of reward' (OR=1.42, 95% CI=1.03-1.95) and 'Occupational climate' (OR=1.55, 95% CI=1.13-2.13) were more likely to experience occupational injury than the other groups.
CONCLUSIONS
Our results tend to suggest that job stress is associated with occupational injury. The importance of job stress should be acknowledged and stress management programs need to be started to minimize the occupational injury caused by job stress.

Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.29

Abstract PDF

OBJECTIVE: The aims of this study were to evaluate the level of job stress in subway workers and to determine the main factors that aggravated their PTSD(Post-Traumatic Stress Disorder) symptom, which were due to having fallen under a train, and to verify the effectiveness of the intervention program.
METHODS
The questionnaires utilized in the survey were composed of the Korean Occupational Stress Scale (the short form, 24 items), the depression scale, the coping scale II, the PTSD scale and the life style, health status and occupational properties. The intervention program for PTSD symptoms was executed for 18 subway operators who had experienced deadly accidents in their service from June 2004 to May 2006. The intervention programs included exercise, meditation and deep breathing for 8 weeks and a written message was sent twice per week.
RESULTS
Compared with pre-intervention, the post-intervention group showed significantly lower scores for the KOSS, depressive symptom and the PTSD.
CONCLUSION
This study showed the intervention program was effective to lower the job stress, the PTSD symptoms and depressive symptoms, and to improve the coping skills. It was suggested that the mental health promotion program should be implemented for subway workers to prevent occupational mental diseases.

The Impact of Weight Changes on Metabolic Syndrome over a Time period of 8 years in Korean Male Workers: Tae Heum Chung, Moon Chan Kim, Ji Ho Lee, Chung Hun Choi, Chang Sup Kim; Korean Journal of Occupational and Environmental Medicine 2010;22(1):20-28. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.20

Abstract PDF

OBJECTIVES
Cardiovascular diseases are common causes of diseases and death for workers. With the increasing prevalence of obesity, the social costs for obesity related diseases are a growing burden in Korea. We aimed to investigate the impact of weight change on metabolic syndrome and its components in Korean male workers.
METHODS
We analyzed the data from 2,785 male workers obtained during health checkups in 2000 and in 2008. The subjects were classified into 5 groups as Loss (< or = -3.0 kg), Stable (-2.9 to 2.9 kg), Mild gain (3.0 to 5.9 kg), Moderate gain (6.0 to 8.9 kg), and Severe gain (> or = 9.0 kg) group according to the amount of weight change between the 2 health checkups. The mean values of metabolic syndrome components were compared across the 5 weight change groups by ANCOVA. After classifying subjects into 2 groups according to the normality of their body weight at baseline, the odds ratios for metabolic syndrome and its components each weight-change group were computed by multiple logistic regression analyses, using the Stable group as the reference.
RESULTS
There was a strong linear relationship between weight gain and a worsening of the components of metabolic syndrome in 2008 (p<0.001). In normal body weight group, the odds ratios for metabolic syndrome significantly increased in the Mild, Moderate, and Severe gain groups (OR 1.83, 2.82, and 7.56, respectively), and increased with weight gain (p<0.001). In subjects who were obese, the odds ratios for metabolic syndrome significantly increased if their amount of weight gain placed them in the Mild or Moderate gain groups(OR 1.75 and 3.97), increased with the increase of weight gain (p<0.001), and decreased in the Loss group(OR 0.51, 95%CI 0.30 to 0.85).
CONCLUSIONS
Weight gain in male workers was positively associated with metabolic syndrome through worsening of metabolic syndrome components. On the other hand, weight loss in obese male workers had a protective effect against metabolic syndrome through the improvement of the components of metabolic syndrome.

Health Effect Assessment on Volunteers Involved in the Cleanup Operation Following the Hebei Spirit Oil Spill Along the Taean Coast, Korea: Chul Ho Lee, Kyung Hwa Park, Min Jung Lee, Wook Hee Choi, Heon Kim, Choong Hee Park, Dae Seon Kim, Seung Do Yu; Korean Journal of Occupational and Environmental Medicine 2010;22(1):11-19. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.11

Abstract PDF

OBJECTIVE: The objetive of this study is to assess the level of oxidative stress by the exposure to volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) in volunteers who cleaned up the crude oil spilled from the Hebei Spirit on the Coast of Taean County, Korea.
METHODS
The study subjects were 46 volunteers and 37 controls from the National Institute of Environmental Research. A self-administered questionnaire was used for volunteers to examine their working environment and health effects. Urinary concentrations of hippuric acid, 1-hydroxypyrene, and 2-naphthol were measured as exposure markers for VOCs and PAHs, and urinary thiobarbituric acid reactive substances (TBARS) and 8-hydroxydeoxyguanosine (8-OHdG) levels were measured as oxidative stress markers.
RESULTS
Sixty-four percent of the respondents presented a variety of symptoms, including sore eyes and throat, nausea, dizziness, headache, low back pain, and leg pain after participating in the cleanup operation. Urinary 2-naphthol and TBARS concentrations appeared higher in the volunteers. Univariate and multivariate analyses showed that urinary TBARS and 8-OHdG levels were positively correlated with urinary 2-naphthol and 1-hydroxypyrene concentrations respectively, especially among the volunteers.
CONCLUSIONS
The result implies that participating in cleanup work of oil spills may have a possibility to induce oxidative damage by exposure to PAHs in crude oil.

Blood and Urinary Cadmium Concentration of Residents around Abandoned Metal Mines in Busan and Gyeongsangnam-do: Hyo Jun Kim, Byoung Gwon Kim, Dae Seon Kim, Jeong Wook Seo, Byeng Chul Yu, Young Wook Kim, Young Seoub Hong; Korean Journal of Occupational and Environmental Medicine 2010;22(1):1-10. Published online March 31, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.1.1

Abstract PDF

OBJECTIVES
To evaluate the blood and urinary cadmium concentration levels of around abandoned metal mines in comparison with a control group.
METHODS
Blood and urinary cadmium concentration levels were analyzed through investigations of the dietary habits and dietary water of subjects living near abandoned metal mines (exposure group) (n=190) in comparison with those living in designated control areas (control group) (n=256).
RESULTS
The blood cadmium (1.93 microgram/l) and urinary cadmium (2.41 microgram/g cr) concentrations of the exposure group were significantly higher than those of the control group (blood cadmium: 1.19 microgram/l, urinary cadmium: 1.94 microgram/g cr). Both concentrations were significantly higher in vegetarians in both groups.
CONCLUSIONS
The exposure group had higher blood and urinary cadmium concentrations than the control group. We attributed the elevated blood and urine cadmium levels in the abandoned mine residents to the influence of the abandoned mine sites.
