From Jan. 1984 to Dec. 1993, 46 patients with malignant germ cell tumor of ovary were identified in tumor registry of Seoul National University Hospital. The clinicopathologic features of these patients were reviewed. The mean age of patient was 21.6 years (range 1-54), and common presenting symptoms were abdominal mass (19/46), abdominal pain (9/46), abdominal distension (7/46), and epigastric discomfort (2/46) in order. Dysgerminoma was the most common histologic type (19/46, 41.3%), followed by endodermal sinus tumor (13/46, 28.2%), mixed germ cell tumor (6/46, 13/0%), embryonal carcinoma(5/46, 10.8%), immature teratoma(2/46, 4.3%), and chorio- carcinoma (1/46, 2.1%). Among 6 mixed germ cell tumors, dysgerminoma mixed with endodermal sinus tumor component was the most frequent combination. Fifty percent of patients were with FIGO stage I, and 26% with stage III. Overall two year disease free survival was 89.1%. Patients with dysgerminoma showed more favorable 2 year disease free survival (100%) than endodermal sinus tumor or mixed germ cell tumor (84.6%, 66.6% respectively). Patients age, disease stage, histologic type and future child-bearings should be considered in the management of malignant ovarian germ cell tumor. Multicenter prospective randomized studies are needed to identify the more rational treatment strateges of these rare malignant tumors.

PURPOSE: The purpose of this study was to evaluate the effect of abutment material on screw-loosening before and after cyclic loading. Among the different materials of abutments, zirconia and metal abutment were used. MATERIAL AND METHODS:: Two types of implant systems: external butt joint (US II, Osstem Implant, Korea) and internal conical joint (GS II, Osstem Implant, Korea) were used. In each type, specimens were divided into two different kinds of abutments: zirconia and metal (n = 5). The implant was rigidly held in a special holding to device ensure fixation. Abutment was connected to 30 Ncm with digital torque gauge, and was retightened in 30 Ncm after 10 minutes. The initial removal torque values were measured. The same specimens were tightened in 30 Ncm again and held in the cycling loading simulator (Instron, USA) according to ISO/FPIS 1480. Cycling loading tests were performed at loads 10 to 250 N, for 1 million cycles, at 14 Hz, (by subjecting sinusoidal wave from 10 to 250 N at a frequency of 14 Hz for 1 million cycles,) and then postload removal torque values were evaluated. RESULTS: 1. In all samples, the removal values of abutment screw were lower than tightening torque values (30 Ncm), but the phenomenon of the screw loosening was not observed. 2. In both of the implant systems, initial and postload removal torque of zirconia abutment were significantly higher than those of metal abutment (P < .05). 3. In both of the implant systems, the difference in removal torque ratio between zirconia abutment and metal abutment was not significant (P > .05). 4. In metal abutments, the removal torque ratio of GS II system (internal conical joint system) was lower than that of US II system (external butt joint system) (P < .05). 5. In zirconia abutments, the difference in removal torque ratio between the two implant systems was not significant (P > .05). CONCLUSION: Zirconia abutment had a good screw joint stability in the condition of one million cycling loading.

PURPOSE: A feasible palliative care model for advance cancer patients is needed in Korea with its rapidly aging population and corresponding increase in cancer prevalence. This study describes the process involved in the development of a community-based palliative care (CBPC) model implemented originally in a Busan pilot project. MATERIALS AND METHODS: The model development included steps I and II of the pilot project, identification of the service types, a survey exploring the community demand for palliative care, construction of an operational infrastructure, and the establishment of a service delivery system. Public health centers (including Busan regional cancer centers, palliative care centers, and social welfare centers) served as the regional hubs in the development of a palliative care model. RESULTS: The palliative care project included the provision of palliative care, establishment of a support system for the operations, improvement of personnel capacity, development of an educational and promotional program, and the establishment of an assessment system to improve quality. The operational infrastructure included a service management team, provision teams, and a support team. The Busan Metropolitan City CBPC model was based on the principles of palliative care as well as the characteristics of public health centers that implemented the community health projects. CONCLUSION: The potential use of the Busan CBPC model in Korea should be explored further through service evaluations.

OBJECTIVES: The purpose of this study was to determine the current status of presenteeism and absenteeism among railroad workers as well as to investigate whether or not job stress level and psychosocial well-being status are associated with presenteeism and absenteeism. METHODS: As the cross-sectional design, a self-reported questionnaire using the Korean Occupational Stress Scale(KOSS), Psychosocial Well-being Index(PWI), and Work Productivity and Impairment-General Health(WPAI-GH) was administered to railroad workers. Univariate and multivariate logistic regressions were used to analyze the association between job stress, psychosocial well-being status and presenteeism, absenteeism in 1,099 subjects. RESULTS: Among the study subjects, 52.0% and 22.0% experiened presenteeism and absenteeism, respectively. Job stress level in railroad workers was higher than that in general workers. Multivariate logistic regression with presenteeism as the dependent variable showed an elevated odds ratio of 3.56(95% CI 1.48-8.54) in the highest job stress group, and an odds ratio of 3.20(95% CI 1.94-5.26) in the high-risk psychosocial stress group. There was no significant association between job stress level and absenteeism, whereas weak association between psychosocial stress and absenteeism was found. CONCLUSIONS: Since railroad workers have a high level of job stress and elevated experience of presenteeism, a management strategy is required to control presenteeism and absenteeism in order to promote railroad workers' health and safety.

BACKGROUND: The recent studies shows that LV relaxation abnormalities are the important factors of heart failure in elders. To determine the association between LV diastolic functions and heart failure, we assessed LV diastolic functions in elderly patients with pulmonary congestion and in asymptomatic elders by using pulsed doppler echocardiography. METHODS: In order to assess LV diastolic function, we performed pulsed doppler echocardiography to elderly patients with pulmonary congestion and asymptomatic elders from Mar.2001 to Sep.2001. The following parameters were used as indices of LV diastolic function; Mitral E wave(E), Mitral A wave(A), Deceleration time(DT), Isovolumic relaxation time(IVRT), Systolic pulmonary venous flow(PVs), Diastolic pulmonary venous flow(PVd). RESULTS: In elderly patients groups, there was significant increase in deceleration time compared with asymptomatic elders(255.83+/-54.41 vs 210.80+/-48.53, p<0.05). There was significant increase in isovolumic relaxation time in elderly patient group compared with asymptomatic elders(123.06+/-25.07 vs 98.78+/-15.12, p<0.01). Although there was no significant difference, decreased E/A ratio and increased PVs/PVd were noted in both groups. CONCLUSIONS: The results shows that the impairments of LV diastolic function were noted in both groups. Especially DT and JVRT were significant increase in elderly patient group with pulmonary congestion. Therefore these parameters, such as DT, IVRT, can be helpful as predictive indices of diastolic heart failure in elders.

Coronary artery disease(CAD), such as atherosclerosis, myocardial infarction and sudden death has been considered the major cause of death for decades and their incidence and prevalence are still increasing. Numerous studies have been done on the risk factor analysis of CAD. But, they were usually based on the clinical and epidemiologic studies of the living patients. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in autopsy cases from Korean men. The author analysed 81 cases of heart who underwent legal autopsy from Aug. to Dec. 1998. The author measured percent stenosis of coronary artery, site of stenosis, perimeter of aorta, heart weight, body weight, and height and checked the past history including smoking, drinking and age. The results were as follows: 1) Coronary artery stenosis had a positive correlation with age, perimeter of aorta and smoking, but had no correlation with body weight, height, body mass index, heart weight, and drinking. 2) According to the logistic regression analysis, smoking amount and age were significantly associated with coronary artery stenosis. In conclusion, smoking was the most significant independent variable for coronary artery stenosis of some Korean men.

Immunoglobulin deficiency with increased IgM, as defined by World Health Organization classification of primary immunodeficiency, is characterized by normal or increased concentrations of serum IgM and, in some cases, IgD, but decreased or absent IgG, IgA, and IgE. Patients with these disorders have a high incidence of recurrent pyogenic infections, including otitis media, pneumonia, and septisemia. We recently experienced a case of immunoglobulin deficiency with increased IgM in a 25-year old man. He had been suffered from recurrent pyogenic infections-pneumonia, otitis media-since about 6 months of his age. He was admitted due to pneumonia, and Haemophilus influenza was isolated from the sputum culture. Also chest X-ray showed bronchiectasis. His serum immunoglobulin levels revealed increased concentration of IgM and decreased IgG and IgA. He was successfully treated with antibiotics, and now he is being followed-up. So we present this case with the review of literature.
