A Study on Correlation between Job Stress and Metabolic Syndrome of Male Employees of Electronic Goods Manufacturer / 한국직업건강간호학회지

PURPOSE: The aim of this study was to investigate the association between job stress and metabolic syndrome among male workers. METHODS: A total of 396 male workers employed in an electronic company, located in 'P' city, Gyeonggi Province, who had taken medical examination at the 'D' hospital, volunteered in this study. All the data used in this study were obtained from 'D' hospital after getting consent and permission from the workers. General and occupational characteristics, medical history, and health-related behaviors of the subjects were obtained by self-administered questionnaire. RESULTS: The highest occupational stress by sub-sector was reported in the order of insufficient job control, organizational system, lack of reward, job demand, job insecurity, physical environment, job culture, and relationship conflict. The prevalence rate of metabolic syndrome of the participants was 19.9%. The results of the multiple logistic regression analysis on metabolic syndrome of the subjects indicated that the syndrome was significantly higher among those with family history, smoking habit and ex-smoking, working duration of 3 years and over, and with higher total score of occupational stress. It was significantly more prevalent, when the degree of stress was high in the sub-sectors of occupational stress; job autonomy, job insecurity, lack of reward, and job culture. CONCLUSION: In conclusion, it is necessary to implement a plan to efficiently manage the job stress of these male workers, as the probability of metabolic syndrome increased with the increase of occupational stress. Furthermore, considering the highest occupational stress was found to be job autonomy among its sub-sectors, it is necessary to prepare various measures to enhance the autonomy of such employees.

The Effect of Unilateral Lateral Rectus Recession for the Treatment of Moderate-Angle Exotropia

PURPOSE: To evaluate the surgical results and the amount of correction per millimeter after unilateral lateral rectus recession for moderate-angle exotropia in a pediatric population. METHODS: This study included 30 subjects who underwent 9-mm unilateral lateral rectus recession for basic type intermittent exotropia with deviation of 23 to 28 prism diopters (PD) and were followed-up for 6 months or more after surgery. RESULTS: Seventeen subjects were male and 13 were female. The mean age of subjects was 9.7 years. Defining satisfactory postoperative ocular alignment as 8PD or less, 25 of 30 subjects (83.3%) were satisfactorily aligned at 2 months postoperatively. The success rates at 4, and 6 months postoperatively were 76.7% respectively. No overcorrected subjects were found after 2 months postoperatively. A postoperative limitation of abduction was not found in all subjects after 2 months postoperatively. The average amount of correction per millimeter of recession at 2, 4, and 6 months was 2.83+/-0.26PD, 2.75+/-0.37PD, and 2.72+/-0.44PD respectively (range, 1.56 to 3.18PD). There was no statistically significant difference in the amount of correction per millimeter throughout the follow-up period (ANOVA, p=0.05). CONCLUSIONS: Unilateral lateral rectus recession appears to be an effective surgical procedure for the treatment of moderate-angle exotropia. However to reduce the rate of undercorrection, which is one of disadvantages of this procedure, proper patient selection is required.

A Case of Primary Central Nervous System Lymphoma with Ocular Involvement

PURPOSE: To report one case of primary central nervous system lymphoma with ocular involvement confirmed by pars plana vitrectomy. METHODS: A 52-year-old healthy man visited our hospital complaining of progressive dysarthria, memory impairment, and chronic headache. Brain CT scans and MRI scans revealed a brain tumor in the left basal ganglia and the frontal lobe. Stereotactic biopsy of the tumor showed a large diffuse B-cell type malignant lymphoma. Three months later, he presented with decreased vision and sensation of floaters in the right eye. Funduscopic examination of the right eye revealed a vitreous opacity peripherally. He underwent pars plana vitrectomy and vitreous biopsy to rule out ocular involvement of lymphoma. Smears from the cytospin of the specimen prepared from vitrectomy in the right eye showed a greater number of large, pleomorphic lymphoid cells. Flow cytometric immunophenotyping showed a clonal population of CD 20 which was conclusive for infiltration with B-cell lymphoma. RESULTS: The patient underwent treatment with radiotherapy to the brain and the right eye in combination with systemic and intrathecal chemotherapy. After five cycles of chemotherapy and radiotherapy, the brain mass disappeared, the neurological symptoms were improved, and the visual acuity of the right eye increased.
