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
AbstractAbstract PDF
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.

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
AbstractAbstract 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.

Imaging Findings among Retired Workers Who Were Long-term Exposed to Asbestos : Lung and Pleural Diseases Prevalence on Chest Radiograph and HRCT
Ki Nam Kim, Jung Il Kim, Ki Nam Lee, Kap Yeol Jung, Joon Youn Kim
Korean Journal of Occupational and Environmental Medicine 2006;18(2):87-93.   Published online June 30, 2006
DOI: https://doi.org/10.35371/kjoem.2006.18.2.87
AbstractAbstract PDF
PURPOSE
To determine imaging findings among retired workers who were long-term exposed to asbestos. Lung and pleural diseases prevalence were studied on chest radiograph and HRCT. MATERIALS AND METHODS: Eighteen workers who were long-term exposedto asbestos occupationally in shipyards were examined by chest radiographs (PA and lateral view) and HRCT (high-resolution computed tomography).
RESULTS
In 12 of 18 subjects (66.7%), asbestos-related pleural abnormalities were evident in diaphragmatic, lateral chest wall and costophrenic angle of the pleura on chest radiographs. The thickness of pleural plaques at the lateral chest wall varied. Diffuse pleural thickening was evident in 2 workers. Parenchymal abnormalities were not found on chest radiographs. On HRCT, pleural thickening wasobserved in 16 of 18 subjects (88.9%), in the areas of juxtavertebral, diaphragmatic, anterior, lateral, mediastinal and fissural pleura. Curvilinear subpleural lines representing early parenchymal asbestosis were found in the lower posterior lung in three of 18 subjects (16.7%).
CONCLUSIONS
In long term asbestos-exposed workers, the asbestos-related pleural disease was 66.7% on chest radiographs and 88.9% on HRCT. The authors suggest that this group should be followed up periodically

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
AbstractAbstract 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.

AbstractAbstract 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
AbstractAbstract 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
AbstractAbstract 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.

AbstractAbstract PDF
OBJECTIVE: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases METHODS: 11 hospitals participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted.
RESULTS
Between Apri1 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. Most of the HAVS cases came from shipbuilding, and 172 of them (92.7 %) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9 %). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6 %) and 4 (12.1 %) cases of occupational asthma, the agents included isocyanate and welding fume, respectively. 64.7 % of the cases of occupational skin diseases were contact dermatitis, and organic solvents and welding fume were the main agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10 (58.8 %) of the cases were diagnosed as squamous cell carcinoma and 5 (29.4 %) as adenoma.
CONCLUSION
This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

Effects of Health on Shift-Work: General and Psychological health, Sleep, Stress, Quality of life
Yoon Gyu Kim, Dong Young Yoon, Jung Il Kim, Chang Ho Chae, Young Seoub Hong, Chang Guk Yang, Jung Man Kim, Kap Yeol Jung, Joon Youn Kim
Korean Journal of Occupational and Environmental Medicine 2002;14(3):247-256.   Published online September 30, 2002
DOI: https://doi.org/10.35371/kjoem.2002.14.3.247
AbstractAbstract PDF
OBJECTIVES
This study was performed to investigate the effects of shift-work, in terms of general health concepts, insomnia, stress, quality of life and psychological health, at several manufacturing plants.
METHODS
Questionnaires were distributed to 850 shift-workers (study group), and to 550 non-shift workers (as a control group). The questionnaires included questions on ; general health concepts, insomnia, stress, quality of life and psychological health. 455 shift-workers and 372 non-shift workers completed the questionnaires, and the factors influencing the health status and quality of life in workers estimated by multiple iogistic regression analysis.
RESULTS
From the general health questionnaires, the mental health and health perception were significantly different between the shift and non-shift workers, with the better being former than the latter (p<0.05). Shift-workers complained of more insomnia when adjusted for age, working period, education and job satisfaction. Greater job satisfaction, was coupled with less complaints of insomnia (p<0.05). There were 200(43.96 %) shift workers classified as insomniac, whereas with the non-shift workers this figure was 84 (25.15 %), showing a significant difference between the two groups (p<0.05). Shift-workers were more stressed than the non-shift workers in their daily lives, which also showed significant difference (p<0.05). Less job satisfaction, was coupled with more complaints of stress (p<0.05). The quality of life of the shift-workers was lower than that of the nonshift workers (p<0.05). With the shift-workers complaining of more anxiety than the nonshift workers (p<0.05).
CONCLUSIONS
Our results suggest that shift-workers suffer from physical and psychological distresses, sleep problems and stress than non-shift workers. Furthermore, it is presumed that these factors might negatively affect the quality of life of shift-workers. Accordingly, interventional methods for shift-worker's health and quality of life as a result of adverse effects of shift-work are needed.

Aluminum Clearance by Hemodialysis in Chronic Renal Failure
Joon Youn Kim, Ki Hyun Kim, Won Suk An, Tae Won Jang, In Sik Kim, Young Seoub Hong, Jung Il Kim
Korean Journal of Occupational and Environmental Medicine 2002;14(1):78-84.   Published online March 31, 2002
DOI: https://doi.org/10.35371/kjoem.2002.14.1.78
AbstractAbstract PDF
OBJECTIVES
This study was carried out to investigate aluminum levels in blood and the factors affecting aluminum concentration; we also presented findings on aluminum clearance during hemodialysis in chronic renal failure patients.
METHODS
We selected 56 patients with case of chronic renal failure and 144 healthy examinees as a control group. We analysed aluminum concentrations in their blood, water and dialysis fluid.
RESULTS
The blood aluminum concentration in the 56 patients was 2.38+/-0.27 microgram/ dL , about 4 times higher than that of the control group (p < 0.01). Blood aluminum concentrations were not affected by factors such as creatinine, BUN, hemodialysis duration, iron, and drinking water. After hemodialysis, blood aluminum level were decreased by about 15% and the aluminum concentration in the dialysis fluid was increased.
CONCLUSIONS
Blood aluminum levels were significantly high in the chronic renal failure patients; and hemodialysis helped the patients to excrete aluminum. Authors suggest that a purified dialysis fluid containing a lower aluminum concentration would facilitate aluminum excretion in hemodialysis patients.

The Relationship between Cold-Exposure and Hypertension
Tae Won Jang, Yoon Gyu Kim, Dong Young Yoon, Chang Hee Lee, Young Seoub Hong, Hae Rim Shin, Kab Yeul Jung, Joon Youn Kim
Korean Journal of Occupational and Environmental Medicine 2001;13(4):376-384.   Published online December 31, 2001
DOI: https://doi.org/10.35371/kjoem.2001.13.4.376
AbstractAbstract PDF
OBJECTIVES
This study was carried out to suggest preventive methods for hypertension in cold-exposed workers.
METHODS
In 11 refrigeration industries, 68 workers working in refrigerated areas more than one time per day were selected as the exposed group, and 68 workers not exposed to cold were selected as the control group. We interviewed the subjects with a questionnaire covering occupational history, and conducted clinical and laboratory tests including measurements of blood pressure and core temperature.
RESULTS
The systolic blood pressure in the exposed group(130.0+/-13.3 mmHg) was significantly higher than that recorded in the control group(118.3+/-12.1 mmHg), as was the diastolic blood pressure in the exposed group(82.7+/-8.5 mmHg) versus the control group(77.4 +/-8.7 mmHg). The core temperature in the exposed group(36.1+/-0 . 7degrees C) was significantly lower than that experienced in the control group(36.4+/-0 . 5degrees C). In logistic regression analysis, age, cold exposure severity and milk intake were significant variables, with odds ratios of 5.204(95 % CI 1.440~18.812), 2.674(95 % CI 1.080~6.618), and 0.364(95 % CI 0.141~0.942), respectively.
CONCLUSIONS
Our study suggests that cold-exposed workers have higher a higher risk of hypertension, and that their core temperature is lower. Risk factors affecting hypertension of cold-exposed workers include age, cold exposure severity and milk intake. For the prevention of hypertension, cold-exposed workers should minimize cold-exposure time as much as possible.

Korean Journal of Occupational and Environmental Medicine 2001;13(3):209-219.   Published online September 30, 2001
DOI: https://doi.org/10.35371/kjoem.2001.13.3.209
AbstractAbstract PDF
OBJECTIVES
This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method.
METHODS
Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS.
RESULTS
18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms(complaint of upper extremities, Visual Analogue Scale >or= 4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group ( p<0.05). The prevalence of symptoms and signs were higher in short term worke r s (<7 years), but the prevalence of CTS was higher in long term workers(>or=7 years).
CONCLUSIONS
The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996

Korean Journal of Occupational and Environmental Medicine 2000;12(4):547-553.   Published online December 31, 2000
DOI: https://doi.org/10.35371/kjoem.2000.12.4.547
AbstractAbstract PDF
OBJECTIVES
To report two cases of neuropathy due to methyl bromide intoxication.
METHODS
Workers, engaged in the fumigating process, complained fatigue, general weakness, ataxia, and hypersomnia. We evaluated them with blood tests, neurophysiologic studies and MRI and investigated their occupational history.
RESULTS
Increased signal intensities were found in the medulla oblongata and paraver mian of cerebellum in MRI and after 11 days, high signal intensities were reduced in the following MRI. In the other case, polyneuropathy and rlght lower brainstem lesion were observed In the NCV and BAEP studies.
CONCLUSIONS
We confirmed that worker's symptoms were related to methyl bromide exposure in the fumigation. It is necessary that we should evaluate present condition of fumigating process and prepare appropriate methods to protect workers engaged in the fumigation.

Jung Il Kim, Tae Hyuk Park, Kap Yeol Jung, Hai Rim Shin, Joon Youn Kim
Korean Journal of Occupational and Environmental Medicine 1999;11(4):516-526.   Published online December 31, 1999
DOI: https://doi.org/10.35371/kjoem.1999.11.4.516
AbstractAbstract PDF
OBJECTIVES
Urinary hippuric acid levels have been usually determined to ' evaluate workers exposed to toluene. Food and drink intake could affect urinary hippuric acid excretion and this study was carried out to investigate what kinds of food and drink would affect urinary hippuric acid excretion.
METHODS
The subjects were 136 medical school students. Authors measured urinary hippuric acid levels three times from 10 a. m. to noon; before, one hour after and two hours after food or drink-intake, and they were asked not to eat from the previous night (9 p. m) of testing. We selected six diets (bread and coffee, brown sauce noodle, Korean style meal, noodle, pork'galbi and rice and soybean stew and rice), six fruits (apple, grape, orange, pear, persimmon and plum) and five beverages (Alps-D(R), Demisoda(R), Orange juice(R), Pear juice(R) and Pocari sweat(R)). Analysis of urinary hippuric acid was performed by high performance liquid chromatography.
RESULTS
Intake of popular Korean diets, fruits and some drinks didn' t affect urinary hippuric acid excretion. But intake of sodium benzoate-contained Alps-D(R) increased urinary hippuric acid excretion.
CONCLUSIONS
For the health examination on workers exposed to toluene, the history of diet and fruit intake can be negligible, but that of beverage intake should be included.

Study on Clinical Significance of High Signal Intensity by Brain Magnetic Resonance Imaging in Mild Steel/Arc Welders (Clinical Significance of High Signal Intensity by Brain MRI in Welders)
Young Seoub Hong, Jung Il Kim, Kap Yeol Jung, Joon Youn Kim
Korean Journal of Occupational and Environmental Medicine 1999;11(3):415-429.   Published online September 30, 1999
DOI: https://doi.org/10.35371/kjoem.1999.11.3.415
AbstractAbstract PDF
OBJECTIVES
This study was carried out to evaluate manganese exposure marker and the clinical significance of high signal intensity observed on brain magnetic resonance imaging(MRI) in mild steel/arc welders.
METHODS
Brain MRI, blood and urinary manganese concentration measurements, physical and neurologic examinations, questionnaire and biochemistry were performed on 53 mild steel/arc welders(exposed group) and 112 non-manganese handling productive workers(control group). We calculated the pallidal index, the ratio of signal intensity of globus pallidus to subcortical frontal white-matter on sagittal 71-weighted MRI. And we studied the relationships between the pallidal index and other measurements.
RESULTS
In 35(66.3%) exposed workers, high signal intensity were observed on the globus pallidus. Blood and urinary manganese levels were higher in exported group than control group. Pallidal index were significantly correlated with working duration, blood manganese level, urinary manganese level and positive rates of clinical symptoms and signs.
CONCLUSIONS
The results of this study suggests that high signal intensity finding on brain MRI may be considered as useful tool for the evaluation of workers who have manganese exposure.

Korean Journal of Occupational and Environmental Medicine 1998;10(2):290-298.   Published online May 31, 1998
DOI: https://doi.org/10.35371/kjoem.1998.10.2.290
AbstractAbstract PDF
We experienced three cases of high signal intensity observed by Brain Magnetic Resonance Imaging in CO2 arc welders of steel-frame manufacturing industry. Case 1 was a 35 years old man who has been an CO2 arc welder for 10 years, admitted a sudden onset of tonic clonic seizure. He complained fever, chilling and myalgia since 3 days before admission. On admission, in the test of manganese exposure indices, manganese concentrations of blood, urine and scalp hair were 5.17 microgram/dL, 22.00 microgram/l and 31.25 ppm respectively. Case 2 was a 35 years old man who has been an CO2 arc welder for 20 years. On admission, He complained fatigue, numbness and weakness of extremities, and decrease of libido. In the test of manganese exposure indices, manganese concentrations of blood, urine and scalp hair were 6.34 microgram/dL, 14.62 microgram/l and 57.87 ppm respectively. In neurologic examination, Palmo-mentis reflex and Myerson sign were observed. Case 3 was a 33 years old man who has been an CO2 arc welder for 16 years. On admission, He complainer loss of appetite, numbness of extremities, fatigue and decrease of attention. In the test of manganese exposure indices, manganese concentrations of blood, urine and scalp hair were 5.14 microgram/dL, 13.79 microgram/l and 50.08 ppm respectively. In neurologic examination, Myerson sign was observed. In brain magnetic resonance imaging, T1WI showed symmetrical high signal intensity in basal ganglia and midbrain of three cases. Authors argued that they were developed by manganese exposure, and we considered that follow up study would be necessary.

Sang Ju Lee, Young Seoub Hong, Sung Ryul Kim, Dong Il Kim, Joon Youn Kim, Kap Yeol Jung
Korean Journal of Occupational and Environmental Medicine 1996;8(2):340-349.   Published online September 30, 1996
DOI: https://doi.org/10.35371/kjoem.1996.8.2.340
AbstractAbstract PDF
A range of indicators is available to assess renal dysfunction in lead exposure. This study was undertaken to find out which indicators were most valuable as markers of renal dysfunction. We selected 75 male workers from the secondary lead smelter, plastic stabilizer and radiator manufacturing industries (the "exposed" group) and 64 male office workers (the "control" group). Blood lead; blood zinc protoporphyrin; urine lead; urine coproporphyrin; delta-aminolevulinic acid dehydratase activity; and urine delta-aminolevulinic acid were chosen as indicators of lead exposure. Blood urea nitrogen; serum creatinine; serum uric acid; urine N-acetyl-beta-D-glucosaminidase; urine albumin; urine alpha1-microglobu-lin; and urine beta2-microglobulin were used as indicators of renal dysfunction. Urine alpha1-microglobulin level was significantly associated with, the lead exposure level. Blood urea nitrogen, urine N-acetyl-beta-D-glucosaminidase and urine alpha1-microglobulin levels were highly correlated with indicators of lead exposure. Urine alpha1-microglobulin had the highest correlation with other indicators of renal function. In addition, the proportion of subjects with high urine alpha1-microglobulin levels showed a gradient with lead exposure. Conclusively, Blood urea nitrogen, urine N-acetyl-beta-D-glucosaminidase and urine alpha1-microglobulin are useful indicators, but urine alpha1-microglobulin is ; the early 'and the most valuable indicator of renal dysfunction related to lead exposure.
