Objective : The heart diseases are known as a major cause of sudden death, as well as a cause of poor life-quality of school-age children. But there have been few mass screening of heart diseases in these children in Korea. This study was done to estimate the prevalence of heart diseases of these population. Methods : We screened all elementary students(grade 1) in 12 cities and 16 counties(Gun) in Kyonggi province from 1992 to 1955. The first screening was done by auscultation of doctors and simultaneously by checking using 'auto-interpreter of EKG-cardiac sound' (Fukuda Densi ECP 50A). We conducted luther examinations to whom classified as being abnormal condition in first screening, by using EKG, chest x-ray, doppler echocardiograpy(if needed). Results : The total number of examined students was 161,308(92% of the population), the male were 83,238 and female were 78,070. The congenital heart diseases(CHD) patients were 290(18 per 10,000) - male 155(18.6 per 10,000) and female 135(17.3 per 10,000). The most frequent disease was ventricula septal defect(VSD, 45.5%), Atrial septal defect(ASD, 14.8%), Tetralogy of Follot(TOF, 11.7%), and Patent Dutus Arteriosis(PDA, 7.6%) in order. In female, the order was VSD(48.1%), ASD(13.3%), TOF(11.1%), and PDA(10.4%). The total number of EKG abnormality were 433(62.7 per 10,000) among 69,056 screened children in 1995. The complete right bundle branch block(CRBBB) and paroxymal ventricular contraction(PVC) were frequent(26.6%, 26.3% in each), and incomplete right bunddle branch block(IRBBB, 14.6%), paroxymal atrial contraction(PAC, 6.7%), abnormal Q(5.8%), Wolf-Pakinson-White syndrom (5.5%) in order. In female, the most frequent abnormality was PVC(29.8%), and CRBBB(19.9%) in order. Conclusion : We could present the stable prevalence of the rare heart disease. The prevalence of congenital heart diseases was 18.0 per 10,000 and of EKG abnormality was 62.7 per 10,000 among school children.

Obesity is correlated with diabetes mellitus, hyperlipidemia, hypertension, cardiovascular, renal, neurologic, psychological and many other disease. Owing to the elevated income and behavioral changes, the prevalence of obesity has remarkably increased in Korea also. Considering the trend of the epidemic, we can easily expect the excessive spendings for the treatment of the obesity-related diseases in near future. In order to check the prevalence of obesity and serum lipid levels of Korean employees, we analyzed the medical check-up sample data of 10,332 adults who took physical check-ups at an institute in 2006. Through the logistic regression analysis we found the prevalence rate of total risk group showing ${\geq}23.0Kg/m^2$ was 57.4% and uric acid was found to be a definitive factor in the prevalence of obesity. Among the adults who eat more meat, drink more and smoke more smoking, the values of BMI, uric acid, cholesterol, HDL- and LDL-cholesterol and TG were significantly higher than rest of the examinees. And the average BMIs were significantly higher among those who have risk factors of liver disease, hypertension, cardiovascular and heart disease, and diabetes mellitus.

Background: Budgerigar fledgling disease polyomavirus (BFDV) is the pathogen that causes budgerigar fledgling disease in psittacine species. The clinical signs of PBFV infection include ascites, hepatitis, and crop stasis. BFDV is associated with a high mortality rate in nestling birds. In contrast, adult birds only have mild symptoms such as feather dystrophy. Objectives: This study aimed to determine the prevalence, genetic characteristics, and phylogenetic analysis of BFDV in pet parrots in Korea. Methods: Fecal and tissue samples were collected from 217 pet parrots from 10 veterinary hospitals including Chungbuk National University Veterinary Hospital. The molecular screening was performed using polymerase chain reaction (PCR) analysis of the small t/large T antigen gene segment. Full-length genome sequencing with the Sanger and phylogenetic analysis were performed on BFDV-positive samples. Results: The PCR results based on the small t/large T antigen gene marker indicated that BFDV DNA was present in 10 out of 217 screened samples. A whole-genome sequence was obtained from six strains and phylogenetic analysis revealed no significant relationship existed between the species and geographical locations amongst them. Conclusions: The prevalence of BFDV infection in South Korea is not high when compared to the prevalence of BFDV in other parts of the world, however, it has been reported sporadically in various species and geographic locations. The whole-genome analysis revealed 0.2%-0.3% variation in intragenomic homogeneity among the six strains analyzed. Korean strains are separately on the phylogenetic tree from their counterparts from China and Japan which might reflect the substantial genetic variation.

The study find out developmental factors of the liver diseases in 29,531 subject of the healthy adults who diagnosed by using ultrasound at healthcare centers located at 6 cities around the nation. The results are as follows. Based on the result of the study, the liver diseases diagnosed by using ultrasound revealed to show 43.1％ of prevalence, and the occurrence was significantly higher in male(23.3％) than in female (19.8％)(p<0.001). The disease revealed to show highest prevalence rate in regionally, Dae-jeon was found to record the highest prevalence by showing 49.6％ (p<0.001). The order of liver disease prevalence was the highest in Dae-jeon(49.6%),which was followed by Seoul(48.2%), Busan(42.9%), Incheon(36.2%), Daegu(36.2%), Kangju(32.1%)(p<0.001). The order of hepatic disease prevalence was the highest in fatty liver (69.7％), which was followed by intrahepatic cysts (13.2％), intrahepatic calcification (9.6％), intrahepatic hemangioma (4.5％), intrahepatic tumor (1.4％), diffuse liver disease (1.0％),and liver cirrhosis (0.5％) (p<0.001). The liver disease revealed to show highest prevalence rate in 40s and regionally, disease was found to record the highest prevalence from 30s to 50s (p<0.001). The distribution of the liver diseases by sex revealed to show the higher occurrence of the fatty liver and the diffuse liver diseases in male, but the intrahepatic cysts, intrahepatic calcification and intrahepatic tumors were highly distributed in female. In the regional evaluation, the fatty liver was most often found in Busan, and intrahepatic cysts, intrahepatic hemangioma, intrahepatic calcification and intrahepatic tumors were highly found in Dae-jeon and Seoul revealed to show higher occurrence of diffuse liver disease than other regions (p<0.001). The multiple regression analysis for the related factors which affect the prevalence of the liver diseases resulted to show the higher prevalence by age. sex,

This study was conducted to identify relationships between lung function disorders and Metabolic Syndrome(MetS) that have common comorbidities such as Cardio Vascular Diseases(CVD). According to the hypothesis that there may be a significant relationship between them, analyses were conducted to identify the proper management point for those diseases. Overall, 53,829 data were taken from KNHANES 2008-2013. Included data were PFT(Pulmonary Function Test) done and age over 40. All the 14 confounders applied, only 8,137 cases (M:3,951, F:4,186) were left. Low pulmonary function was divided into two categories, obstructive and restrictive patterns, based on the Global Initiative for Chronic Obstructive Lung Disease(GOLD) criteria, while MetS was defined based on the revised NCEP-ATPIII criteria. The relationships between those diseases were analyzed using logistic regression analysis. In addition, for the prevalence rate, cross-tab analysis were conducted. There were no significant relationships observed between obstructive lung disease and MetS, but a restrictive pattern had a meaningful relationship with MetS. Specifically, MetS showed a higher prevalence rate for both obstructive and restrictive pattern patients than the control group. Restrictive pattern patients showed a higher prevalence rate to MetS than obstructive patients. Overall, restrictive lung patterns showed a meaningful association with MetS, but not with obstructive patterns. Additionally, the prevalence rate of MetS among restrictive patients was higher than among obstructive patients.

Purpose : The aim of this study was to determine the epidemiology of Kawasaki disease in the Kyung Nam area and to evaluate whether the results of this epidemiological study could support infectious etiology. Methods : We sent a questionnaire to three training hospitals in the Kyung Nam area and retrospectively reviewed their medical records of Kawasaki disease from Jun. 1995 to Dec. 1999. Results : The total number of patients was 717 cases, with little differences of annual prevalence during the five years. In all cases, the monthly prevalence of Kawasaki disease was high in Apr. and Jul. At the eastern of Kyung Nam, the monthly prevalence was high in Apr. and Jul. in 1995 and 1996, Jul. in 1997, Apr. in 1998 and Apr. and Jul. in 1999. In the central area of Kyung Nam, the monthly prevalence was high in Apr. in 1995 and 1996, Apr. and Jul. in 1997 and Jul. in 1998 and 1999. In the western Kyung Nam, the monthly prevalence was high in Nov. in 1995, Aug. in 1996, Oct. in 1997, Dec. in 1998 and Nov. in 1999. Conclusion : In the eastern and central areas of Kyung Nam, the monthly prevalence of Kawasaki disease was similarly high in Apr. and Jul. However, in the western district, the prevalence was high in late fall and winter. We could not prove the hypothesis that Kawasaki disease occurred with the spread of single infectious agent, but the a nnually similar prevalence in eastern and central Kyung Nam supported the infection theory for the etiology of the disease.

Purpose: The purpose of this study was to investigate disease prevalence, parent's educational needs, and disease management according to severity of respiratory infections in early childhood. Methods: Participants for this study were 173 mothers whose child was admitted to I university hospital in Seoul and whose child was an infant or toddler. Data were collected from December, 17, 2014 to February, 15, 2015 using self-report structured questionnaires. Data were analyzed using IBM/SPSS 21.0 program. Results: There were significant differences in the severity of respiratory infection according to neonatal admission due to dyspnea, feeding type, atopic dermatitis in the infant or allergic disease in father and siblings. Parent's educational needs for the severe respiratory infection group were higher than for the non-severe group. Parent's disease management for the severe respiratory infection group was lower than the non-severe group. Conclusion: As important care factors in neonatal admissions include dyspnea, cow milk feeding, eczema, family history of allergies, parent's educational needs and disease management, they should be considered when caring for young children with respiratory infections and their parents.
