A Statistical observations were done on 587 pediatric patients who were diagnosed as having congenital heart disease by cardiac catheterization angiography and operation at Dong San Hospital Keimyung University, during the period of January 1982 to june 1987. The results were as follows 1) Out of 587 patients, 317 cases were male and 276 cases were female. There were female preponderance in atrial septal defect and patent ductus arteriosus, whille in male tetralogy of Fallot, pulmonary stenosis, and ventricular septal defect. 2) The incidence of congenital heart disease were as folliws;ventricular septal defect 35.7% tetralogy of Fallot 17.5%, patient ductus arteriousus 13.9%, arterial septal defect 7.5% and pulmonary stenosis 2.9%. 3) Most of the patients were visited hospital for the first time between the age of 2 and 10 years. 4) Assosiated anomalies of major congenital heart disease were as follows:the most commonly associated anomaly in ventricular septal defect were pulmonary stenosis and patent ductus arteriosus. Pulmonary stenosis was frequently associated with atrial septal defect. Right sided aortic arch and pentalogy were assosiated with tetralogy of Fallot. The mitral regurgitation was associated with patent ductus arteriosus mostly. 5) The overall surgical mortality was 6.8%. The mortality was high in tetralogy of Fallot(16.1%), transposition of great vessels(28.5%).

BACKGROUND AND PURPOSE: Wandering is one of the most common behavioral and psychological symptoms of dementia, and associated with some of the adverse outcomes in dementia, such as getting lost or even death. The etiology of wandering is not yet clearly known. As depression and wandering are both very common among the patients with dementia, this study examined the relationship between the depression and wandering among the community dwelling patients with dementia. METHODS: Fifty community dwelling patients diagnosed with dementia were included in this study if they had primary family caregiver, older than age 18 in Seoul, South Korea. The Geriatric Depression Scale, Korean Version (GDS-K), Korean Version of the Mini-Mental State Examination (K-MMSE) and Korean Version of Revised Algase Wandering Scale-Community Version (K-RAWS-CV) were used to measure the severity of depression, cognitive function and wandering. RESULTS: Thirty percents of the patients showed wandering. Mean score of GDS-K was significantly higher in wanderers than non-wanderers. Severity of depression was significantly correlated with the total score of K-RAWS-CV and subscales of persistent walking, repetitive walking, eloping behavior, and mealtime impulsivity in whole sample. K-MMSE score also was related to wandering behavior. The prevalence odds ratio for wandering in depressed patients compared with undepressed group was 8.386 (95% confidence interval: 1.978-35.561). CONCLUSIONS: This study implicates that not only cognitive impairment but also psychosocial aspects should be considered in wandering patients with dementia and suggests assessing the depression in patients would be helpful in identifying the causes of wandering.

PURPOSE: Increase in the use of diagnostic imaging or occupational exposure to radiation have brought upon concerns on the safety and biological effects of low- or moderate-dose radiation. However, limited information is available on the effects of low or moderate dose radiation on human health. METHODS: Using C57BL/6 mice, we aimed to evaluate the biological effects of low- and moderate-dose radiation on the immune system. X-rays was chosen as a radiation source and we analyzed complete blood counts, various lymphocyte subsets and various cytokine levels after single fraction x-ray exposure (0.1 Gy, 1 Gy). RESULTS: No significant changes in the immunologic parameter of C57BL/6 mice were observed after radiation, except LIX (a cytokine equivalent to human CXCL5), that showed higher level after 0.1 Gy radiation compared to the control. CONCLUSION: We observed that a single fraction of low or moderate dose of X-ray radiation does not cause significant changes in the immune system of C57BL/6 mice. Further studies are necessary to elucidate the mechanism underlying our results.

BACKGROUND AND OBJECTIVES: The therapeutic duration of variant angina is controversial. This study sought to determine the remission rates for coronary artery spasms, the factors associated with remission and the changes in spasm sites. SUBJECTS AND METHODS: Fifty-eight patients were enrolled in the study. Initial, and follow-up, coronary angiographies (CAG), with ergonovine stimulation tests, were performed. Paired CAG were performed at a mean interval of 27+/-17 months. Medication was stopped 3 days prior to the follow-up CAG, and the occurrence of chest pain during these 3 days was studied. Coronary spasms were confirmed by follow-up CAG. Any changes, and the diameters, of spasm sites were analyzed on each paired CAG. RESULTS: The remission rate of coronary spasms was 24% (14 patients), when the smoking group (49 patients) stopped smoking (31 patients), the remission rate was 29% (9 patients). In the current smoking group (18 patients), the remission rate was 6% (1 patient, p=0.05). 31 patients had chest pains after stopping medication prior to their follow-up CAG. Of those patients, 1 patient had a remission (3%). Among another 27 patients with no chest pain, 13 patients had a remission (48%, p<0.001). In 28 out of 44 patients (64%, non-remission), fluctuations in spastic locations were observed at the follow-up CAG. The interval changes in the diameter of the spasm sites were not significant. CONCLUSION: The non-chest pain group showed higher remission rates, but lack of chest pain did not identify the loss of coronary spasm. Atherosclerosis at spasm sites did not progress, as confirmed by the paired CAG in our study.

Five patients with favorable outcomes after a shunt operation in normal pressure hydrocephalus were analyzed with the aim of identifying consistent findings in a lumbar puncture (LP) test. The cases commonly showed improvement in at least one cognition and two gait LP parameters. We suggest that when judging the effects of LP on a shunt operation, the gait parameters need to be tailored to the gait status and the analyzed LP parameters should be evaluated at least twice at different times.

To examine the influence of the duration of menopause on bone loss, 60 healthy women, aged 34~74 years in 1995 were studied. After exclusion of past or present hormonal replacement therapy or past history of chronic disease, 60 women formed the final study population. Bone masses were measured at 3 sited of femur(femoral neck, Wards triangle and trochanter) and in the L2~L4 lumbar spine by Dual energy X-ray bone densitometry(DEXA). Correlation analysis and multiple linear regression analysis were used to analyze the relationships of gynecological variables(age, body mass index:BMI), and years since menopause(YSM) with bone mineral density(BMD) of lumbar spin and the three different sites of femur. The coefficients of correlation(r) of the bone mineral density(%) at the lumbar spine and the three different sites of femur with YSM were ranged -0.37~-0.48(p < 0.01). Only YSM was independently related to BMD(%) data at all sites, except Wards triangle by multiple linear regression analysis(p < 0.01). In conclusion, the menopause and the duration of menopause have a great effect on bone mineral loss.

PURPOSE: Fine needle aspiration (FNA) is a useful preoperative diagnostic tool for thyroid nodule because of the high sensitivity and specificity. The aim of this study is to determine the necessity of intraoperative frozen section (IOFS) after fine needle aspiration. METHODS: Data of 534 patients with a single thyroid nodule who underwent thyroidectomy from June 2006 to August 2013 were reviewed retrospectively. FNA was performed preoperatively in all patients and IOFS was performed selectively according to the intraoperative findings and FNA results. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of FNA and IOFS for malignant nodules were analyzed. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FNA for malignant nodules were 100%, 95.5%, 99.8%, 100%, and 99.8%, respectively. All nodules diagnosed as benign by FNA were reaffirmed as benign nodules by permanent sections. When the result of FNA was suspicious for malignancy, specific features of preoperative ultrasound, including hypoechoic, size<10 mm showed high positive predictive value and accuracy (98%, 86.9%, and 100%, 78.7% respectively). CONCLUSION: Performance of IOFS was not necessary when the result of FNA was consistent with malignancy or benign. However when the result of FNA was non-diagnostic or atypia, IOFS should be performed for more accurate detection of malignancy. When the result of FNA is suspicious for malignancy, IOFS is restrictively useful for excluding benign nodules using the features of ultrasound. In addition, IOFS is not useful in finding malignant thyroid nodules when the result of FNA is follicular neoplasm.
