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

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.

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.

Survey on the Prevalence of Carpal Tunnel Syndrome in Simple Repetitive Workers Who Use Upper Extremities: Ji Eun Son, Tae Woon Jang, Yoon Kou Kim, Young Seoub Hong, Kap Yeol Jung, Dong Ill Kim, Kang Jin Lee, Nam Jin Ha, Sang Boum Kim, Joon Youn Kim; 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

Abstract 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

Two Cases of Neuropathy by Methyl Bromide Intoxication during Fumigation: Tae Hyuk Park, Jung Il Kim, Ji Eun Son, Jong Kuk Kim, Hyung Soo Kim, Kap Yeol Jung, Joon Youn Kim; 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

Abstract 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.
