The clinical symptom complex characterized by syncopal attacks and sudden death in patients with electrocardiographic anomalies, especially a prolonged Q-T interval is known as the Romano-Ward syndrome. When a similar symptom complex is accompanied by congenital deafness, it is called Jervell and Lange-Nieisen syndrome. This study was undertaken to investigate the investigate the incidence of the latter syndrome in the Seoul area. A total of 1,013 children with congenital deafness who attend schools for the deaf were studied by analyzing their electrocardiograms. A corrected Q-T interval of> or =0.44 seconds was defined as a prolonged Q-T interval. The overall incidence of long Q-T syndrome observed in the deaf in the Seoul area was 0.49% as compared to 0.25% reported from elsewhere in the world. The mean age of patients with long Q-T syndrome was 11.3+/-5.9 years and the first syncopal attacks was 4.6+/-1.1 per patient. A valsalva maneuver and exercise tests in the test group were associated with significant changes in T wave configuration and prolonged Q-T intervals while similar changes were not observed in the control group. A larger survey is needed to derive more statistically significant conclusions.

PURPOSE: Infrared thermometers are increasingly used as a convenient, non-invasive assessment method for febrile children. However, the diagnostic accuracy of the infrared thermometer for children has been questioned, particularly in relation to sensitivity and specificity. The aim of this study was to evaluate diagnostic accuracy of infrared thermometers in febrile children. METHODS: Articles published between 1966 and 2012 from periodicals indexed in the Ovid Medline, Embase, CINAHL, Cochrane, KoreaMed, NDSL, KERIS and other databases were selected, using the following keywords: 'infrared thermometer'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4. RESULTS: Nineteen diagnostic studies with high methodological quality, involving 4,304 children, were included. The results of meta-analysis showed that the pooled sensitivity, specificity and AUC (Area Under the Curve) of infrared tympanic thermometers in children over 1 year were 0.80 (95% CI 0.78, 0.81), 0.94 (95% CI 0.93, 0.95) and 0.95 respectively. However the diagnostic accuracy of infrared tympanic thermometers in children with hyperthermia was low. CONCLUSION: The diagnostic accuracy of infrared tympanic thermometer was similar to axillary and rectal thermometers indicating a need for further research to substantiate these findings in children with hyperthermia.

BACKGROUND: This study was carried out to examine the trends of government-supported health promotion research projects conducted in Korea over the past 12 years. METHODS: Research type, area of interest, organization, and expense of 726 research projects conducted from 1998 to 2009 were examined and the health promotion content analyzed. RESULTS: In Korea, 361 health policy researches (HPR) and 365 general health researches (GHR) were supported by the government during the defined time period. A total of 60.5 health promotion research were conducted annually with a total amount of 27.1 billion won provided (2.26 billion won per year). With the average research project lasting 8.5 months, HPR (7.7 months) projects were completed sooner than GHR (9.2 months). Those who majored in preventive medicine completed 177 research (24.4%), the most number of research projects, followed by public health (22.5%), and family medicine (15.6%). There were 641 health promotion research projects done mostly on policies, legal systems, and grasping current conditions, and only 85 (11.7%) clinical test research on the development or effects of health promotion programs. CONCLUSIONS: HPR have been increasing annually. However, our study could not be certain of how close the studies were to the government's health promotion policies. Furthermore, the main health promotion area, 'healthy living', was not researched as often as should be. Additionally, to improve applicability of the research projects, interdisciplinary cooperation should be promoted.

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.

Primary chondrosarcoma of the extraskeletal soft tissue is extremely rare. Extraskeletal chondrosarcoma was first described as entity in 1953 by Stout and Verner, who were able to collect a series of seven cases. Because of the rarity of this lesion in extremities, neither the clinical course nor the preferred method of treatment has been clearly established. Authors report a case of extraskeletal chondrosarcoma which occurred on the right forearm of a thirty-nine-year-old man. The lesion was completely excised with free resection margins. There was no recurrence or metastasis for four years follow up.

PURPOSE: This study investigated evidence for the use of relaxation therapies as interventions to decrease irritable bowel syndrome (IBS) symptoms and severity as well as reduce anxiety and improve quality of life in IBS patients. METHODS: A search of electronic bibliographic databases (e.g., Medline Ovid, Embase, KoreaMed, and National Discovery for Science Leaders) was conducted to identify randomized controlled trials that included relaxation exercise programs for adults (>18 years old) with IBS. Of the 486 publications identified, 8 studies met inclusion and exclusion criteria, and all studies were used in the meta-analysis. We used Cochrane's risk of bias to assess study quality. RESULTS: The results showed that IBS symptoms decreased significantly, 6.19 (95% confidence interval [2.74, 14.02]) and there was no heterogeneity. Symptom severity and anxiety decreased by 0.38 (95% confidence interval [-1.41, 0.65]) and -0.08 (95% confidence interval [-0.38, 0.23]) due to relaxation therapies, but theses scores were not statistically significant. CONCLUSION: This review revealed positive effects of relaxation therapy on IBS symptoms in adult patients with IBS. However, these results should be interpreted with caution due to the small number of studies examined and the associated methodological problems. Further studies are needed to ascertain the longterm effects of relaxation therapy and the underlying psychosocial mechanisms leading to anxiety reduction and improved quality of life.

PURPOSE: The purpose of this study was to determine whether upright position is effective in labor through systematic review in randomized controlled trials. METHODS: We established the PICO (Patient-Intervention-Comparator-Outcome) strategy, and reviewed 282 literatures from national and international electronic databases, and finally selected 9 references based on inclusion and exclusion criteria. We evaluated the quality of references and carried out a meta-analysis. RESULTS: The maternal outcomes showed that the duration of their second-stage labor was 2.29 minutes shorter than that of the women in the recumbent position, and were less likely to have episiotomy. The other outcomes, including the mode of delivery, blood loss, hemoglobin level, use of oxytocin, use of analgesics, and perineal laceration, did not differ between the groups. The fetal heart rate abnormality occurred less than in the control group. The Apgar scores of the groups did not differ. CONCLUSION: There is evidence that an upright position in the second stage of labor reduces the duration of the second stage of labor, the incidence of episiotomy, and an abnormal fetal heart rate.
