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.

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%).

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.

PURPOSE: Serum alkaline phosphatase (sALP) levels show great variation with age and sex in children and adolescents. We aimed to study pediatric age- and sex-specific reference ranges for sALP and how the pattern changed according to age . METHODS: Cross-sectional results from 1366 healthy Korean children and adolescents (10-19.9 years) from the Korean National Health and Nutrition Examination Survey were analyzed. We constructed age- and sex-specific reference data for sALP with a Hitachi Automatic Analyzer 7600 using Pureauto S ALP. We assessed its peak both in relation to age. RESULTS: Reference values for sALP according to age were constructed. Peak sALP levels were found at 12-13 years in boys (P < 0.001). Total sALP levels decreased to the adult level at the age of 17 in boys and 15 in girls, respectively. CONCLUSION: This study provides reference values for sALP by age for Korean children and adolescents. This normative data that includes upper and lower limits will provide a basis from which to better evaluate sALP levels, especially for bone disorders such as rickets and vitamin D deficiency. However, caution should be made in interpreting sALP levels because different buffers might lead to different values in the same serum.

PURPOSE: Accurate diagnosis of acute pyelonephritis(APN) using clinical and laboratory parameters is often difficult in children. Clinical and experimental studies have demonstrated that renal scarring can be prevented or diminished by early diagnosis and aggressive treatment of acute pyelonephritis. dimercaptosuccinic acid(DMSA) renal scan has been reported to be useful in children for confirmation of the diagnosis of acute pyelonephritis. An analysis was undertaken to correlate the clinical and laboratory manifestations of APN with the results of the DMSA renal scan in different age groups. METHODS: We determined the sensitivity of DMSA renal scan in febrile urinary tract infections(UTI) in two groups according to age:group I in less than 2 years; group II in older than 2 years. During the period March 2001 through September 2002, 67 children presented with febrile UTIs. All patients had DMSA renal scan done in the acute period, 55 had voiding cystourethrography(VCUG) and 66 had renal ultrasonogram(RUS) done. RESULTS: There were no significant difference between the two groups in DMSA renal scan (P>0.05). But, in group I sensitivity of DMSA renal scan was 47%; in group II sensitivity of DMSA renal scan was 70%. The grade of reflux correlated with a positive DMSA renal scan. Vesicoureteral reflux did not correlate with age. RUS did not correlate with a positive DMSA renal scan in any age group. Abnormality of RUS did not correlate with age. CONCLUSION: At present, we believe that DMSA renal scan is the prevailing method in differention of the APN. In addition, it is not invasive and less costly. Even though there is no statistical difference in the sensitivity of DMSA renal scan between young and older children, we can observe that in the younger group, the sensitivity of DMSA renal scan seemed to be lower(47%).
