CHAP syndorme consists of choreoathetosis, orofacial dyskinesia, affective change, hypotonia, and pseudobulbar signs. CHAP syndrome was firstly des- cribed with onset 1 to 7 days after induced profound hypothermia and complete circulatory arrest for con- genital heart lesion repair. Since then, only a few cases have been reported until now. Case We report a patient who demonstrated all of the elements of the CHAP syndrome in severe cachexic state. Brain SPECT(99mTC-ECD) shows decreased perfusion in left fronto-parieto-temporal lobe. Comments The pathogenesis of CHAP syndrome is obscure. However our case led us to suggest that more essential component pre- disposing to the CHAP syndrome is hypoxia rather than hypothermia. Furthermore, it seems to be related with circulatory insufficiency in extrapyramidal nervous systems.

INTRODUCTION: The objective of the present study was to investigate the independent effects of major depressive disorder (MDD) and insomnia on somatization, respectively. METHODS: A total of 181 participants (73 males and 108 females ; mean age 41.59+/-8.92) without serious medical problem were recruited from a community and a psychiatric clinic in Republic of Korea. Subjects were divided into 4 groups based on the Structured Clinical Interview for DSM-IV axis I disorder (SCID-IV) and sleep questionnaire : 1) normal controls (n=127), 2) primary insomnia (n=11), 3) MDD without insomnia (n=14), and 4) MDD with insomnia (n=29). All participants were requested to complete the somatization subscores of the Symptom Checklist-90-Revised (SCL-90-R). RESULTS: There were significant between-group differences in somatization score (F=25.30, p<0.001). Subjects with both MDD and insomnia showed higher somatization score compared to normal control (p<0.001), subjects with primary insomnia (p=0.01), or MDD subjects without insomnia (p<0.001). Subjects with primary insomnia had higher somatization score than normal controls (p<0.01), while there was no significant difference between MDD subjects without insomnia and normal controls. In multiple regression, presence of insomnia predicted higher somatization score (beta=0.44, p<0.001), while there was only non-significant association between MDD and somatization (beta=0.14, p=0.08). CONCLUSION: In the current study, insomnia was associated with somatization independently from major depression. Subjects with primary insomnia showed higher somatization. Within MDD patients, presence of insomnia was related to higher somatization. Our finding suggests that insomnia may partly mediate the relationship between depression and somatization.

OBJECTIVES: The purpose of this study was firstly to introduce a Participatory Action-Oriented Training (PAOT) program for the prevention of work-related musculoskeletal diseases (WRMSDs) in Small and Medium sized Enterprises in the Gumi Industrial Zone, and secondly to assess its effect. METHODS: Two PAOT workshops to prevent WRMSDs were conducted with 39 volunteer participants from 10 companies selected (on a first-come, first-served basis) among 200 small- or medium-sized enterprises in Gumi. These companies had been provided with mandatory occupational health management agency services for Small and Medium sized Enterprises by an occupational medicine clinic. Each workshop consisted of 6 technical sessions and one closing ceremony. At the 1st session, the principles of each action checklist item were explained and an on-site checklist exercise was carried out. The 2nd to 5th sessions presented good example pictures on 4 subjects: material storage and handling, working environment, work organization and work-related welfare. Group discussions were carried out by the participants. In the final 6th session on the implementation of improvement, each participant was asked to present 6 action plans, 3 short-term and 3 long-term, for their own workplace improvement. RESULTS: Overall, the participants worked out 47 real action plans, 27 short-term and 20 long-term, for improvement of their own workplaces. Three to 6 months after the workshops, through in-person visits to each company, it was confirmed that more than half of these 47 plans had been completed; 25 plans (53.2%) had been completed as planned, 8 (17.0%) were in processing, and 14 (29.8%) had not yet been put into practice. CONCLUSIONS: The study findings confirmed that the PAOT program holds strong potential as an intervention method to prevent WRMSDs in Small and Medium sized Enterprises, although the final results have not been fully assessed yet.

OBJECTIVES: This study aimed to analyze the relationship between clinical status and work characteristics of firefighters and other public officers who engaged on collection duties in the site of the hydrogen fluoride spill that occurred on September 27, 2012, in Gumi City, South Korea. METHODS: We investigated the clinical status, personal history, and work characteristics of the study subjects and performed physical examination and several clinical examinations, including chest radiography, echocardiography, pulmonary function test, and blood testing in 348 firefighters, police officers, volunteer firefighters, and special warfare reserved force who worked at the hydrogen fluoride spill area. RESULTS: The subjects who worked near the accident site more frequently experienced eye symptoms (p = 0.026), cough (p = 0.017), and headache (p = 0.003) than the subjects who worked farther from the accident site. The longer the working hours at the accident area, the more frequently the subjects experienced pulmonary (p = 0.027), sputum (p = 0.043), and vomiting symptoms (p = 0.003). The subjects who did not wear respiratory protective devices more frequently experienced dyspnea than those who wore respiratory protective devices (p = 0.013). In the pulmonary function test, the subjects who worked near the accident site had a higher decease in forced vital capacity than the subjects who worked farther from the site (p = 0.019); however, no statistical association was found between serum calcium/phosphate level, echocardiography result, chest radiographic result, and probation work characteristics. CONCLUSIONS: The subjects who worked near the site of the hydrogen fluoride spill, worked for an extended period, or worked without wearing respiratory protective devices more frequently experienced upper/lower respiratory, gastrointestinal, and neurological symptoms. Further follow-up examination is needed for the workers who were exposed to hydrogen fluoride during their collection duties in the chemical plant in Gumi City.

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.

Pneumoconiosis is one of the most important occupational disease in Korea. In Pusan, most of pneumoconiosis is welders' pneumoconiosis developed in shipyard. With clinical (including interview with every patients) and radiological (chest radiographs) methods, author purposed to know the factors related to development of pneumoconiosis in shipyard welders and to apply the results to the concept for health care (management) of shipyard welders. The prevalence rate of welders' pneumoconiosis was calculated by the means of reading of chest radiographs of 547 shipyard welders. The prevalence rate of welders' pneumoconiosis (including suspected pneumoconiosis, category 0/1) was 7.9%. It was lower than that (8.9%) in same area studied in 1989. Prevalence rate increased as total welding duration increased and the welding work began early. It was higher in welders who did not use antidust mask. Probability of the occurance of welder's pneumoconiosis was related with the time that the welder began welding work. Sixteen cases among the 37 who were diagnosed as pneumoconiosis returned normal in the follow-up chest radiographs. There was no case aggrevated. The pertinent management for the personnels and their working environment contributed to the decrease of incidence of the welders' pneumoconiosis and the improvement of the disease. To prevent the occurance of the pneumoconiosis in shipyard welders, it seems to be necessary for the company to be supervised under the any legislation and to educate the welder to use the protective apparatus. It is suggested that considerate and continuous observation under the adequate management is preferable to the immediate conversion of the working department for the pneumoconiotic welders.

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.

Primary malignant melanoma of the esophagus is a rare, but aggressive tumor with a fatal prognosis. Hematogenous and lymphatic metastasis are common. The tumor has multiple black and pigmented lesions. Resection of the tumor with an anastomotic procedure is the treatment of choice. Despite this operation, the prognosis is quite poor with the mean life expectancy being less than 1 year. We describe here a case of a 54-year-old man with esophageal malignant melanoma, and we also include a review of the relevant literature.
