This study was conducted from November 1, 2017 to November 30, 2017 in 268 women in late postmenopausal period in D and S shipyards located in G city. The subjects were divided into two groups according to the risk factors of cerebrovascular disease according to the presence or absence of risk factors of cerebrovascular disease. The subjects were divided into two groups according to their general characteristics, cerebrovascular disease prevention knowledge, attitude and health behavior. The variables that had statistically significant difference in health group and risk group were age (F=92.239, p<.001), cohabitation type ($x^2=20.056$, p<.001), income level ($x^2=39.023$, p<.001), the number of working hours per week (F=32.217, p<.001), the number of working years (F=12.310, p=.001), family history of cardiovascular disease ($x^2=233.442$, p<.001), subjective health status($x^2=19.058$, p=.001). There was a significant difference between the two groups in the degree of knowledge related to prevention of cardiovascular disease (F=2.679, p=.008) and health behavior fulfillment (F=4.339, p<.001). (r=.348, p<.001), the risk group had a higher knowledge (r=.279, p=.002), and the other group Attitude (r=.194, p=.030) showed a statistically significant correlation. Based on this, it is necessary to develop and apply an intervention program considering the characteristics of vulnerable group of cerebrovascular disease.

Objective : Accumulating evidence suggests a greater number of subcortical hyperintensities in the brain of patients with bipolar disorder. We studied the Clinical correlates of subcortical hyperintensities on magnetic resonance imaging in patients with Bipolar Disorder : Methods : Magnetic resonance images of the brain were obtained for 32 patients with bipolar disorder. The presence and location of hyperintensities were assessed. We compared clinical variables between patients with subcortical hyperintensities and patients without them. Results : Seven patients(21.8%) had subcortical hyperintensities, but among 8 patients who were 40 years or older, 5 patients(62%) had them. Age and age at onset of patients with subcortical hyperintensities were significantly older than patients without them. Psychotic symptoms were more frequent in patients with hyperintensities. Patients without hyperintensities had more familial loadings. Conclusion : Given the limitations of the study, our results should be seen as preliminary. This study, however, provides preliminary evidence supporting the notion that the onset, clinical feature and course of some bipolar disorders of late onset may be determined by underlying subcortical abnormalities, with such abnormalities being the consequence of factors related to aging or neurodegeneration(such as impaired cerebral circulation) rather than genetic factors which predispose to early-onset bipolar disorders.

Purpose: To evaluate treatment outcomes of malignant melanoma and to analyze the factors that contributes to outcomes. Materials and Methods: We reviewed the 51 cases of malignant melanoma from March, 1997 to March, 2004 and were followed up more than 5 years. Average age was 49.4. We compared 5-year survival rate for each age, gender, site of occurrence, depth of tumor, metastasis of regional lymph node and immuno-chemo therapy. Results: 5-year survival rate was 88.5% for the age group below 65, 88.0% for the age group 65 and above, 62.5% for male and 100% for female. 5-year survival rate for the site of occurrence showed 100% in upper extremities, and 80.0% in lower extremities and 100% in other sites. 5-year survival rate was 100% for the stage below Clark stage III and 79.3% for the stage above IV. In surgical resection, 5-year survival rate was 66.7% for lymph node metastasis group and 94.9% for non-lymph node metastasis group. Conclusion: The prognostic factors of malignant melanoma were gender, tumor site, depth of tumor (Clark's stage) and metastasis of regional lymph node. But, there was no relation between the age and the survival rate in our study.

Purpose : We hypothesized that the mannose binding lectin gene (MBL2), a key molecule of innate immunity may contribute to the development of Kawasaki disease (KD) in early childhood. This study was performed to investigate the polymorphisms of MBL2 and the risk of developing KD in Korean children. Methods : The study subjects were 112 children with KD who were admitted to the Seoul National University Bundang Hospital between October 2003 and March 2005. The control subjects consisted of 224 anonymous, healthy Korean blood donors. Extracted genomic DNA was amplified for codon 54 of MBL2 exon 1 and alleles (a and b) were assigned via sequencing analysis. The frequency of the alleles of the MBL2 exon 1 was compared between the case and control groups. Results : The median age of patients was 27 months (range, 3 months-7 years), 45.5% were <24 months of age and 54.5% were ${\geq}2$ years. The genotype distribution reached Hardy-Weinberg equilibrium in both cases and control subjects. In the cases with KD, the genotypic frequencies of codon 54 polymorphisms were 67.9% for aa, 29.5% for ab, and 2.6% for bb. There were no significant differences in the overall distribution of the polymorphisms between the cases and the control subjects. In addition, the genotype distribution was not different according to age. Conclusions : Our findings indicate that the codon 54 polymorphism of the MBL2 gene is not likely to contribute to the risk of developing KD in Korean children. Further studies on the development of coronary artery lesions with regard to MBL2 genotypes are warranted.

Purpose : To identify the necessity of more reasonable diagnostic criteria and the possibility of early prediction of coronary involvement in the higher risk group, we investigated and compared clinical and laboratory findings in the acute phase and coronary involvements in those younger (n=17) and older(n=53) than one year of age in Kawasaki disease(KD). Methods : Retrospective chart reviews were performed on 70 patients with KD who were admitted to the Chung-Ang University Hospital from April 1997 to May 2001. Results : Male were significantly higher in the younger age group(M : F ratio 3.3 : 1 vs. 1.0 : 1, P=0.004). Fever durations before intravenous immunoglobulin(IVIG) and echocardiography were significantly shorter in the younger group($4.6{\pm}1.3$ vs. $6.2{\pm}2.5$, P=0.004 vs. 0.01, respectively). Cases meeting typical diagnostic criteria were significantly less in the younger group(P=0.006). In the laboratory findings, serum albumin, BUN and $K^+$ levels in the acute febrile phase were significantly higher in the younger group(P=0.002, 0.006, <0.001, respectively) and incidences of coronary artery dilatation in the acute phase were significantly higher in the younger group(P=0.01). Conclusion : Although less met the typical diagnostic criteria of KD, infants younger than one year of age are more susceptible to coronary artery change in the acute febrile phase. Therefore, KD should be entertained as a diagnostic possibility in young infants with prolonged fever without distinct fever focus, and echocardiography should be considered as part of the evaluation of these patients, and then early diagnosis and prompt IVIG should be conducted.

Purpose : Juvenile rheumatoid arthritis(JRA) is one of the most common rheumatic diseases of childhood and is an important cause of short- and long-term disability. The purpose of this study was to determine the disease course and outcome in childhood patients with JRA. Methods : Fifty nine patients with JRA who were diagnosed and treated in the Department of Pediatrics, Asan Medical Center from August 1990 to November 2004 were enrolled in this study. Sex, age, type, affected joints, extra-articular manifestations, laboratory and radiologic findings, treatments, and outcomes of JRA patients were reviewed retrospectively. Results : Among JRA patients, 32.2 percent had pauciarticular type, 30.5 percent had polyarticular type and 37.3 percent had systemic type. The ratio of boys to girls was 1.7 : 1 and the mean age at onset was $9.3{\pm}3.7$(1.3-15.9) years. The most commonly affected joints were knee, ankle and wrist. The extra-articular manifestations observed were fever, rash, myalgia and lymph node enlargement, etc. The main laboratory findings observed were leukocytosis, anemia, thrombocytosis, elevated ESR, and elevated CRP. Rheumatoid factor and antinuclear antibody(ANA) were positive in 5.3 percent and 18.0 percent. Nonsteroid anti-inflammatory drugs(NSAID) were used most frequently and methotrexate with or without steroids was added in 27.1 percent of patients unresponsive to NSAID. 88.1 percent of patients were cured without functional disability and only one patient was in functional status IV. One patient, who had pulmonary involvement, died. Conclusion : Our results showed an even distribution in type of onset, male predominance, older age of onset, low incidence of iridocyclitis, and low positivity of ANA in JRA patients; this differs from occidental data. This study may suggest regional differences and variability in disease groups of JRA among different racies, but further multi-center trials and large scale epidemiological studies are needed to confirm our conclusion.

Objective：The enlargement of the lateral ventricle is well established finding in adult-onset schizophrenia, but in the patients with early-onset psychotic disorder(EOPD) is still controversal. To identify structural abnormalities of the lateral ventricle in patients with EOPD and difference of the brain developmental course in EOPD group, planimetrical assessment of the lateral ventricle was conducted by means of retrospective quantitative neuroimaging. Methods：The brain MR images of 14 patients with EOPD(mean age $14.0{\pm}2.1$ years) who met the DSM-III-R diagnostic criteria for schizophrenia and bipolar disorder and 24 control subjects with simple headache(mean age $10.0{\pm}2.1$ years) were collected. Single best view for the lateral ventricle, one axial slice was selected for analysis. MR images were redigitalized with flatbed scanner and data were analyzed with NIH IMAGE software. Results：In the patients with EOPD, there were significant correlations between aging and lateral ventricular sizes and between aging and ventricular brain ratio(VBR). The statistical significance of normal asymmetry of the lateral ventricle was not observed for the EOPD group. The EOPD group had larger lateral ventricular sizes and VBR than control group, but these results were not statistically significant. Conclusion：These findings suggest that the brain abnormalities in patients with EOPD progress from the earlier course of the disorders and the course of brain development in EOPD group is different from control group.

Purpose : The aim of this study was to determine whether differences exist in the presentation, clinical course, and outcome of Graves' disease between prepubertal children and adolescents. Methods : A retrospective chart review of 14 prepubertal(PREPUB, $7.2{\pm}0.9yr) and 38 pubertal (PUB, $12.4{\pm}1.5yr$) children with Graves' disease between January 1989 and November 1995 at St. Mary's Hospital and Kangnam St. Mary's Hospital was undertaken. Results : There were no significant differences in $T_3$, $T_4$, TSH between two the groups at diagnosis. The PUB group had significantly higher titers of antimicrosomal antibody(positive dilution factor $11,727.3{\pm}22,888.4$) than did the PREPUB group($2,111.5{\pm}2,285.0$, P<0.001). The PREPUB group had significantly higher titers of TSH-binding inhibitory immunoglobulin(TBII, $62.5{\pm}39.6$) than did the PUB group($44.9{\pm}10.4$, P<0.05) before treatment started. The duration(months) of medical therapy before thyroid function tests were normalized was longer in the PREPUB group than in the PUB group($T_3:6.8{\pm}5.0$ vs. $5.4{\pm}13.2$, $T_4:2.3{\pm}1.9$ vs. $2.1{\pm}2.2$, $TBII:26.7{\pm}24.0$ vs. $20.8{\pm}12.1$), especially that of TSH was significantly longer in the PREPUB group($14.6{\pm}11.0$ vs. $6.8{\pm}7.8$, P< 0.05). Total length of medical therapy was significantly longer in the PREPUB group than the PUB group($52.3{\pm}19.3$ vs. $37.9{\pm}16.3months$, P<0.01). During three years of antithyroid drug therapy, in the PREPUB group, the remission rate was lower and the relapse rate was higher than in the PUB group. Total length of treatment correlated negatively with chronological age(P=0.03). Conclusion : Prepubertal children require longer medical therapy to achieve a remission than do pubertal children. But there is an obvious need for more studies because of the small number of patients and the short duration of the follow-up.

Purpose : It is known that 3-50 percent of type 1 diabetes mellitus(T1DM) patients develop autoimmune thyroid disease. We analyzed the clinical characteristics of autoimmune thyroid disease(AITD) developed in patients with T1DM in Korean. Methods : The medical records of 139 patients, who were followed up in Department of Pediatrics, Seoul National University Children's Hospital from Jan. 1981 to Jul. 2004, were analyzed retrospectively. Results : Forty-four males and 95 females were enrolled. At least one of the autoantibodies for thyroid was positive in 54 cases. The detection rate for AITD was not correlated with sex ratio, control of T1DM, body mass index, age at diagnosis of T1DM, and familial history of thyroid disease, between two groups. In the male group, AITD was more frequently found at a younger age than in the female group. The frequency of AITD was significantly higher in the goiter group without sex differences. In the thyroid disease group, 40 patients(74.0 percent) were euthyroid, seven patients(12.9 percent) were hypothyroid, and seven patients(12.9 percent) were hyperthyroid. Conclusion : We should monitor thyroid function and autoantibodies routinely in T1DM patients who develop goiters, or young boys with T1DM.
