Seven Cases of Respiratory Symptoms Caused by Acute Ozone Exposure from an Electronics Company: Yong Jun Kwon, Kuck Hyun Woo, Jin Seok Kim, Seong Yong Yoon, In Ung Song, Jay Young Yu, Seong Yong Cho; Korean Journal of Occupational and Environmental Medicine 2012;24(4):449-459. Published online December 31, 2012; DOI: https://doi.org/10.35371/kjoem.2012.24.4.449

BACKGROUND
Ozone is a colorless, pungent, and highly reactive gas. It can cause headaches, burning eyes, irritation to the respiratory passages, and dyspnea. This article describes cases of respiratory difficulty associated with acute ozone exposure from an electronics company that manufactures touchscreen.
CASE
REPORT: Seven young female workers visited the Department of Occupational and Environmental Medicine, complaining of cough, dyspnea, and chest discomfort that started within two days at work processing a touchscreen with ozone (0.103 ppm ozone detected in the their workplace). Other; symptoms observed included rhinorrhea, headaches, and dizziness. There was a temporary improvement in symptoms upon taking a day off, but their symptoms deteriorated upon continuing work again-suggesting the ozone exposure in their work environment was responsible for their symptoms. The results of pulmonary function and blood laboratory tests were normal; however, laryngoscopy and nasal endoscopy identified three cases of inflammation on laryngeal, intranasal, or vocal cord regions.
CONCLUSIONS
Based on the levels of ozone detected in the workplace and clinical symptoms presented, we conclude that the respiratory symptoms in these cases were caused by excessive ozone exposures.

Published online June 30, 2012; DOI: https://doi.org/10.35371/kjoem.2012.24.2.133

Abstract PDF

OBJECTIVES
The purpose of this study was to develop a program applying participatory action-oriented training (PAOT) methods for the management of cardiovascular disease risk factors and to assess its effectiveness in the workplace.
METHODS
The cardiovascular disease risk factors of 817 workers in the workplace were assessed, and periodic health examination was conducted. Sixty-four workers (7.8%) were selected as a moderate-risk group and high risk group, and performed the participatory approach program for cardiovascular disease preventive management.
RESULTS
The sixty-four workers who participated in the participatory approach program made a total of 246 action plans, 3.8 action plans per person and 115 action plans were achieved after three months, so that 46.7% of action plans have been achieved. In the intervention group that participated in the program, the rate of smoking decreased from 36.2% to 8.6% and systolic and diastolic blood pressure significantly decreased from 140.0+/-9.4 mmHg to 134.2+/-12.3 mmHg and from 92.6+/-7.1 mmHg to 80.0+/-9.8 mmHg respectfully. In addition, risk factor score also decreased by 0.3, whereas the control group who did not participate in the program also showed a significant reduction in the mean systolic and diastolic blood pressure. Regular exercise increased from 8.5% to 16.0%.
CONCLUSIONS
To improve the effectiveness of the participatory approach program for the management of cardiovascular disease risk factors, the need to continues implementing programs and analysis of the long-term effects are required.

The Association between Trans, Trans-Muconic Acid as a Biomarker for Benzene Exposure and the Platelet Count: Young Sun Min, Kuck Hyun Woo, Jin Seok Kim, Jay Young Yoo, Kwan Lee, Hyun Sul Lim, Heon Kim; Korean Journal of Occupational and Environmental Medicine 2010;22(2):95-101. Published online June 30, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.2.95

Abstract PDF: OBJECTIVE: Recent researches suggest that trans,trans-muconic acid (t,t-MA) would be an adequate metabolic biomarker for low-level benzene exposure. Few study have investigated the association between the t,t-MA and platelet count, and this is the primary aim of this study.
METHODS
From May 2004 to June 2004, 326 chemical factory workers took part in a questionnaire survey and they underwent urinary t,t-MA and CBC assessment. The questionnaire covered general aspects of health and the occupational and smoking histories. Statistical analyses of outcomes were performed using SPSS 14.0 for Windows.
RESULTS
The subjects' urinary t,t-MA concentration (geometric mean and geometric standard deviation) was 0.28 mg/g creatinine (2.62). No significant differences between different occupations among the chemical workers were found. The urinary t,t-MA concentrations in the smokers and non-smokers were 0.32 mg/g creatinine (2.44) and 0.25 mg/g creatinine (2.77) respectively, and the difference was statistically significant (p<0.05). There was no significant difference in the platelet count based on occupation and the smoking history. There was significant correlation between log(platelet) and log(t,t-MA)(r=-0.116 p=0.039). The regression equation log(platelet) = -0.002xAge + [-0.029xlog(t,t-MA)] + 2.436, R2=0.032, was calculated from linear regression analysis with log(platelet) as the dependent variable. Cross-tabulation between 2 subgroups that were divided by the 90-percentile level of the t,t-MA (0.819 mg/g creatinine), and 2 subgroups that were divided by the 10-percentile level of the platelet count (175,000) was conducted. Higher distribution in subgroup with platelet count below 175,000 was demonstrated in the subgroup with a urinary t,t-MA above the 90-percentile, with an odds ratio of 3.01.
CONCLUSIONS
The study may be limited by not taking into account factors such as smoking quantity and sorbic acid, which may confound urinary the t,t-MA concentration as well as medication and infection that may affect the platelet count. Yet it is meaningful that the correlation between the urinary t,t-MA concentration and the platelet count was found through linear regression analysis and the chi-square test, and further, this outcome may be used as a basis for a study to establish the acceptable limit of urinary t,t-MA in Korea.

A Case of Peripheral Polyneuropathy Induced by Occupational 2,5-hexanedione Exposure: Seong Yong Cho, Yong Seok Jang, Eun Kyung Choi, Jin Seok Kim, Jay Young Yu, Kuck Hyun Woo, Tae Seong Choi; Korean Journal of Occupational and Environmental Medicine 2007;19(1):73-80. Published online March 31, 2007; DOI: https://doi.org/10.35371/kjoem.2007.19.1.73

Abstract PDF

OBJECTIVES
This study is a case report of 2,5-hexanedione induced occupational peripheral polyneuropathy. We also investigated the peripheral nerve function of all workers who had been exposed to 2,5-hexanedione in the same process.
METHODS
In June, 2006, a 2,5-hexanedione exposed worker complained of both hand numbness. He received neurologic, radiologic, laboratorial and electrophysiologic evaluation, including measurements of workplace environment. Five months after cessation of exposure to 2,5-hexanedione, a follow-up electrophysiologic examination was done. We evaluated the peripheral nerve function of 2,5-hexanedione exposed workers by comparing 13 male 2,5-hexanedione exposed workers who were in same company with the patient and 5 male workers who had not been exposed to 2,5-hexanedione.
RESULTS
Under electrophysiologic examination, there were abnormalities in sensory and motor nerve velocity, terminal latency, and F-latency of both median nerve and ulnar nerve. After 5 months, the patient symptoms and the results of follow-up electrophysiologic examinations were improved. Comparing the 2,5-hexanedione exposed group with the unexposed group, the sensory nerve velocity of the median and ulnar nerves in the exposed group was decreased. The motor nerve velocity of the peroneal nerve, and sensory nerve velocity of the median and sural nerves were decreased. Terminal latency of median, ulnar, peroneal, and tibial nerves in the exposed group were increased compared with the unexposed group(<0.05).
CONCLUSIONS
2.5-hexandione can induce peripheral polyneuropathy in male workers.

Published online September 30, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.3.246

Abstract PDF

OBJECTIVES
The main goal of this study was to find the incidence of the dimethylacetamide (DMAc) induced toxic liver injury among workers who were exposed to DMAc for about 5 years in a synthetic fiber factory.
METHODS
In our investigation, total 1,021 workers had been exposed to DMAc from 1st February, 2000 to 30th June, 2004. Among them, 24 workers who had initial abnormal hepatic enzyme level or was viral hepatitis B carrier were excluded. Finally, 997 DMAc exposed workers were followed up for their incidence of toxic liver injury. To find out DMAc induced toxic liver injury case, we carried out regular examinations including liver enzyme tests such as AST and ALT.
RESULTS
We followed up 997 workers and among them 72 cases coincided with our case definition. Incidence density method was 6.05 per 100 person-year. and, a cumulative incidence by life table method was 0.0965 within a year. The incidence of the DMAc-induced toxic liver injury peaked at 4 to 5 in weeks after employment. There was no toxic liver injury case within second week after exposure to DMAc. Five new cases developed in 2th to 3th week, 25 cases in 4th to 5th week, 14 cases in 6th to 7th week, 12 cases in 8th to 9th week, 5 cases in 10th to 11th week, 4 cases in 12th to 13th week, 4 cases in 14th to 15th week, 1 case in 16th to 17th week, 1 case in 30th to 31th week, and there was one case in 48th to 49th week.
CONCLUSIONS
The incidence rate of toxic liver injury was considerably high during the 1st year after a worker is placed. So it is needed to take careful monitoring of hepatic enzyme level for newly exposed worker.

A Case of Toxic Hepatitis in a Worker Exposed to a Cleansing Agent Mainly Composed of Methylene Chloride: Bong Goo Ha, Jin Seok Kim, Jay Young Yu, Kuck Hyun Woo, Jung Oh Ham, Seong Yong Yoon, Yong Seok Jang, Sang Je Jung; Korean Journal of Occupational and Environmental Medicine 2004;16(2):210-219. Published online June 30, 2004; DOI: https://doi.org/10.35371/kjoem.2004.16.2.210

Abstract PDF

OBJECTIVES
To report a case of toxic hepatitis in a worker exposed to a cleansing agent mainly composed of methylene chloride.
METHODS
A 27-year-old female worker who had worked in an inspection and packing position of semiconductor parts in a factory using methylene chloride as a metal cleansing solvent was hospitalized due to fever, chill and generalized aches. We evaluated her with blood tests, abdominal ultrasonographic scan and abdominal CT scan and also took her occupational history.
RESULTS
The patient showed acute hepatitis in blood and radiologic tests after admission. The serologic tests for viral hepatitis A, B, C and autoimmune hepatitis were negative. She had no history of significant alcohol use, recent medication or drug allergy. After admission, her symptoms were improved and liver enzyme levels(AST and ALT) were markedly reduced. She returned to her workplace after discharge. Thereafter, however, her previous symptoms were recurred and she was hospitalized again 2 days after returning to her workplace. After this second admission, she showed acute hepatitis in blood tests and her symptoms were improved and liver enzyme levels were markedly reduced with the same pattern as those of the first admission. On the 11th day of the second admission, liver enzyme levels were normalized and she was discharged from hospital.
CONCLUSIONS
We presume that this patient`s liver injury was related to the methylene chloride presence at her workplace due to her clinical symptoms, blood tests, radiologic tests and occupational history.

Incidence and related factors of fatty liver among male workers: Jin Seok Kim, Jong Young Lee, Kuck Hyun Woo, Jay Young Ryu; Korean Journal of Occupational and Environmental Medicine 2003;15(3):310-322. Published online September 30, 2003; DOI: https://doi.org/10.35371/kjoem.2003.15.3.310

Abstract PDF

OBJECTIVE: This study was conducted to investigate the incidence rate of fatty liver and it's related factors based on a three year follow up of multiphasic health screening participants.
METHODS
671 male workers who had participated in both initial and second multiphasic health screening were selected. Initial screening was performed during the year of 1996 to 1997 and second screening was performed during the year of 1999 to 2000. Among them, four hundred and thirty workers who didn't initially have a fatty liver were selected as the final study subjects. They were classified into 2 categories according to the initial and second hepatic ultrasonographic findings; stationary normal(307, 71.4%), and fatty liver incident(123, 28.6%). The incidence rate was calculated using the incidence density method.
RESULTS
The incidence rate of fatty liver among the male workers was 9.73 per 100 person-years. The white collar workers had a higher incidence rate(10.66) than the blue collar workers(8.14). The incidence density ratio of alcohol drinking to fatty liver incidence was 1.41, and the incidence density ratio of low vegetable diet was 1.63. The incidence density ratio of obesity was 1.78 for the 100-109% obesity index group, 2.83 for the 110-119% obesity index group, 4.25 for the >or=120% obesity index group over <100%. Smoking, regular exercise, salty food preference, and taking food supplement had no significant effect on the incidence of fatty liver. The fatty liver incident group had higher initial blood pressure, GPT, gamma GTP, fasting blood sugar, HbA1c, uric acid, total cholesterol and triglyceride levels than the stationary normal group. However, there were no differences in the GOT, HDL-cholesterol or LDL-cholesterol levels. In the multiple logistic regression analysis, obesity index and serum triglyceride were found to be major factors in the incidence of fatty liver after controlling age, alcohol drinking, vegetable diet, daily coffee intake, blood pressure, HbA1c, total cholesterol, and uric acid levels.
CONCLUSION
The incidence rate of fatty liver among the male workers was 9.73 per 100 person-years. The lifestyles which gave rise to an increasing incidence of fatty liver were those involving excessive alcohol drinking, obesity, and low vegetable diet. Moreover, many cardiovascular disorder related health indices such as blood pressure, and the blood sugar, blood lipid and uric acid levels, were related to the incidence of fatty liver.

Surveillance of Work-related Diseases in Kumi: Seong Ah Kim, Jin Seok Kim, Hae Ree Jeon, Sang Jae Jung, Sang Woo Kim, Chae Yong Lee, Jung O Ham, Jay Young Yoo, Tae Sung Choi, Ha Bong Goo, Min Hwan Cho, Kuck Hyun Woo; Korean Journal of Occupational and Environmental Medicine 2003;15(1):95-110. Published online March 31, 2003; DOI: https://doi.org/10.35371/kjoem.2003.15.1.95

Abstract PDF

OBJECTIVES
Area-based occupational disease surveillance in Kumi (KODS) was used to collect data on occupational diseases. The data was used to estimate the magnitude of the diseases, to analyze for their characteristics, and to find links for their intervention and prevention.
METHODS
Since January 2001, occupational physicians and nurses in Occupational Health Service (OHS)have reported six major occupational diseases; occupational musculoskeletal disorders of the upper extremities(MSDUE), occupational dermatoses, toxic hepatitis, occupational asthma (OA), hand-arm vibration syndrome(HAVS), and occupational cancer. For the respective diseases, a reporting sheet and operational diagnostic criteria were developed by the KODS. An analysis of the KODS data, collected over a certain period, was compared with data from the Korea Labor Workers Corporation (KLWC) and the Specific Health Examination (SHE), and the incidence rates of the diseases estimated.
RESULTS
Between Jan 2001 and Apr 2002, 287 cases of the six major occupational disease were reported. Of these, there were 132 (46.0%), 100 (34.8%), 34 (11.8%), 16 (5.6%), and 5 (1.7%), cases of MSDUE, occupational dermatoses, toxic hepatitis, OA, and HAVS, respectively. But, there were no cases of occupational cancer. 33 (11.5%) of the incidence were reported via the OHS, 206 (71.7%) from health checkups, and the other 48(16.8%) from other routes. The synthetic fibers and electronic components manufacturing industries accounted for the greatest number of reported cases. With respect to occupation, the greatest numbers of incidence were reported from the elementary occupations, textile workers, assemblers, and cooks and food services worker, in that order. Of the MSDUE cases, carpal tunnel syndrome and epicondylitis were the two most common diseases. Most of the occupational dermatoses were due to contact dermatitis, with organic solvents (59%), nickel (6%), and epoxy resin (5%) accounting for the majority of these cases. All cases of toxic hepatitis were induced by dimethylformamide or dimethylacetamide, which were reported by a unique monitoring system. During same period, there were no cases claimed by workers to the KLWC, and only three cases from SHE, were identified. Using data from workers' number and surveillance, the annual incidences of MSDUE, dermatoses, hepatitis, OA, and HAVS, per 100,000 workers were 63.6, 48.2, 17.9, 7.7, and 2.4, respectively.
CONCLUSIONS
These results show that an area-based surveillance system can be very effective for the collection of data on work-related diseases, at least in Kumi.

Ocular, Respiratory and Skin Symptoms Among Solderers Employed in Printed Circuit Board Assembly Units: Jay Young Yu, Kuck Hyeun Woo, Jin Seok Kim, Jung Oh Ham, Tae Sung Choi, Bong Goo Ha, Sang Je Jung, Shin Goo Park, Il Ryong Kim; Korean Journal of Occupational and Environmental Medicine 2001;13(4):423-435. Published online December 31, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.4.423

Abstract PDF

OBJECTIVES
This study was conducted to evaluate the prevalence of ocular, respiratory and skin symptoms among solderers and to investigate the relationship between symptom prevalence and exposure intensity.
METHODS
We analyzed 126 eligible participants out of a population of 146 male solderers who completed the symptom questionnaires. Fourteen symptoms including 'itchy and red eyes', 'itchy or prickly nose', 'sneezing', 'rhinorrhea', 'blocked nose', 'pricklythroat', 'foreign body sensation in throat', 'sudden bouts of coughing', 'exertional breathlessness ', 'wheezing', 'sputum production', 'itchy face or hands', 'acneiform eruptions on the face'and 'red spots on the face or hands'were contained. Blood lead levels of all the 126 participants were tested and the participants'own assessments of the health risk of soldering were collected.
RESULTS
Of the 14 investigated symptoms, 'sudden bouts of coughing'was significantly more prevalent in solderers who worked 4 hours or more a day than those who worked less than 4 hours a day, as for the other symptoms, there were no significant differences in the preva1ences related to daily soldering hours. 2.8% of the solderers considered the risk of flux exposure to be serious. The mean blood lead level was 6.05 microgram/dL (maximum 15.50 microgram /dL).
CONCLUSIONS
Soldering may increase the risk of respiratory symptoms. Further investigations on the hazards of soldering processes are warranted and solderers should be educated on these hazards.

Toxic Hepatitis Induced by Occupational Dimethylacetamide Exposure: Tae Sung Choi, Kuck Hyeun Woo, Jin Seok Kim, Wan Seup Park, Jung Ho Ham, Sang Je Jung, Jae Young Yu; Korean Journal of Occupational and Environmental Medicine 2001;13(2):164-170. Published online June 30, 2001; DOI: https://doi.org/10.35371/kjoem.2001.13.2.164

Abstract PDF

Dimethylacetamide is widely used in the production of plastics, resins, synthetic fibers, and gums and in purification and crystallization processes. Inhalation of the vapor or skin absorption of the liquid of dimethylacetamide(DMAC) can cause liver damage. Toxic hepatitis possibly attributable to DMAC exposure occurred in seven works among 178 employees who had worked on a new spandex-fiber production line. A large amount of DMAC is used as a spinning solvent for synthetic fibers in the factory. The patients were aged 23-47 years old and composed of five males and two females. They were involved in the process of polymerization(1 patient), spinning(1), take-up(4) and packaging(1). The mean duration of exposure was 10 weeks. They experienced fatigue, dizziness and jaundice. The patients showed elavated total bilirubin, alanine aminotransferase(ALT), and aspartate aminotransferase(AST) levels. The serologic test for viral hepatitis A, B and C were negative, as were the abdominal ultrasonographic scans. Based on the presumptive diagnosis of DMAC-induced toxic hepatitis, they were removed from the workplaces. One or two months after removal from the work, the transaminase levels returned to normal. The patients had no history of significant alcohol use, blood transfusion, recent medication, and drug abuse. As a result, authors could not find any attributable cause of toxic hepatitis but the toxicity by DMAC exposure.

Abstract PDF: OBJECTIVE: This study was carried out to determine the effects of occupational pesticides exposure on the level of serum Luteinizing Hormone(LH), Follicle Stimulating Hormone(FSH), testosterone in male workers.
METHODS
Twenty-two male workers exposed to pesticides were compared with twenty-eight male workers at same factory who were not exposed to pesticides. The selected variables for studying reproductive hormones were LH, FSH and testosterone. As part of the baseline health status, subjects were asked medical history.
RESULTS
There were no statistically significant differences on the level of LH, FSH, testosterone between the exposed and non-exposed group. Also the level of sex hormones were not significant difference with each department in exposed group. And the level of LH, FSH positively correlated with age.
CONCLUSIONS
These results indicate that there are no alterations in LH, FSH, testosterone at workers exposed to pesticides. But our findings are highly preliminary because of a small sample size. Thus it calls for furthur investigation of the hormonal effects at workers exposed to pesticides.

Abstract PDF

OBJECTIVES
The purpose of the study was to assess the risk factors assumed to be related to the high frequency hearing loss in the noise-exposed male workers.
METHODS
712 occupationally noise-exposed male workers were included in this cross sectional study. The subjects filled out a questionnaire on the history of noise exposure, hearing protection, otologic diseases, tobacco smoking, and were tested on height, weight, hematocrit, serum total cholesterol level, fasting plasma glucose level and arterial blood pressure level. Pure tone audiometry and otoscopy were conducted and the subjects were allocated into two groups according to whether they had 4000 Hi hearing loss or not.
RESULTS
The multiple logistic regression analysis showed that military noise exposure, poor wearing status of the hearing protection devices, increased age, long noise exposure duration, mean arterial pressure less than 80mmHg, high fasting plasma sugar are the factors significantly related to high frequency hearing loss (P<0.05). On the contrary, there was no significant relationship between noise intensity, body mass index, serum total cholesterol level, smoking and high frequency hearing loss. Low hematocrit was shown to be a significant factor with a p-value less than 0.1.
CONCLUSIONS
High frequency hearing loss in the noise-exposed male workers is related to military noise exposure, use of hearing protection devices, age, noise exposure length, fasting glucose level and mean arterial pressure, in this order. Appropriate use of the hearing protection devices has a great impact on the prevention of the noise-induced hearing loss.

Two Cases of Convulsion Associated With Caprolactam: Kuck Hyeun Woo, Sang Je Jung, Wan Seup Park, Hea Ryeon Shin, Jin Seok Kim, Sang Woo Kim; Korean Journal of Occupational and Environmental Medicine 1998;10(1):116-120.

Abstract PDF: Two young men were seen with nausea, vomiting, dermatitis, seizure after two-four days of occupational exposure to caprolactam, a nylon fiber precursor. There were no significant results in laboratory test, brain CT, EEG except leukocytosis, hyperglycemia. Caprolactam has been shown to induce convulsive disorder in experimental animal studios and Tuma et al (1981) described that one worker acutely exposed to caprolactam developed generalized tonic-clonic seizure with leukocytosis. The coincidence of typical skin lesion with otherwise unexplained generalized tonic-clonic seizure in those young man strongly suggests that caprolactam was causal agent.
