PURPOSE: The purpose of this study is to determine factors affecting happiness of adolescents who attended community child centers. METHODS: We surveyed 154 adolescents attending a community child center in P City with a structured self-report questionnaire from October 3 to October 15, 2016. Data was analyzed by SPSS 18.0 descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients and stepwise multiple regression. RESULTS: The mean scores of family strength, friend support, teacher support, and happiness were 3.8±0.84, 3.8±0.98, 3.7±0.84 and 3.7±0.63. There were significant differences in happiness according to the subjects' number of close friends and duration of their stay at the community child center. There were a significant positive correlations among family strength, friend support, teacher support, and happiness. The most significant factors affecting happiness included friend support (β=.40) and peaceable family strength (β=.35). These variables explained 44% of the total variance in happiness. CONCLUSION: It is desirable to prepare and support measures to increase friends' support and family strength in order to improve happiness of adolescents attending community child centers. The findings suggest that it is necessary to develop nursing intervention programs to promote friend support and family strength.

Behcet disease is a chronic systemic inflammatory disease involving mucous membranes, skin, eyes, gastrointestinal tract, joints, vessels, and neurologic systems. The disease usually manifests in early adulthood. Childhood onset is rare. We experienced a case of Behcet disease in a 11-year-old boy. He suffered from recurrent arthritis of the left knee joint which was managed under the impression of septic arthritis since he was seven years old. Behcet disease should be considered in case of recurrent arthritis mimicing septic arthritis in children.

OBJECTIVE: To evaluate the incidence, combined anomaly, and prognosis of prenatally diagnosed Single Umbilical Artery (SUA) by ultrasound. METHODS: From January 2001 to December 2005, a single umbilical artery (SUA) was observed in 41 cases out of 22,868 deliveries. Among 41 cases, 39 cases were examined by targeted imaging to rule out fetal anomalies in the mid trimester (intrauterine pregnancy 16-27 weeks). The remaining two cases were detected in the third trimester, which were transferred from a local clinic, and were examined by routine sonogram. Pregnancy and perinatal outcome data were retrieved by review of the medical records. RESULTS: The incidence of SUA in our population was 0.18%. Of 41 fetuses with SUA, 8 cases presented congenital malformations (19.5%) such as acrania (n=1), Tetralogy of Fallot (n=1), renal anomalies (unilateral renal agenesis n=2, pyelectasis n=1), esophageal atresia (EA) with tracheoesophageal fistula (TEF)(n=1), omphalocele with choroid plexus cyst (CPC)(n=1), and congenital diaphragmatic hernia with hypoplastic left heart syndrome (n=1). Of 33 fetuses with isolated SUA, 3 (9.1%) demonstrated growth restriction. Karyotype analysis was performed in three cases. Two were normal and omphalocele with CPC was Trisomy 18. CONCLUSION: During the prenatal period, the fetus with SUA by ultrasound examination must be carefully monitored with targeted prenatal ultrasound because of its frequent association with fetal congenital anomalies (19.5%). Isolated SUA without associated anomaly dose not affect the outcome of the pregnancy.

Lymphangiomatosis is a condition of lymphatic tissue malformation with multiple or diffuse involvement of soft tissues, visceral organs. Congenital abnormalities of the lymphatic system are very rare, and reports of congenital lymphangiomatosis are even fewer. We experienced a case of congenital lymphangiomatosis detected as edema of the right limb by prenatal ultrasonography and then diagnosed by magnetic resonance imaging. We describe this case with a brief review of the literature.

Intussusception is a frequent cause of bowel obstruction in the first five years of life and it is one of the most common surgical emergencies in infancy and early childhood. The age of five months child was administered in Department of Pediatrics of Chunchon Sacred Heart Hospital. His main symptoms were vomiting and high fever for three days. Abdominal sonography, air reduction and abdominal computerized tomography (CT) were performed and the conclusion of these study was intussusception due to cyst mass lesion; duplication cyst, mesenteric cyst or Meckel's diverticulum. He was transferred for operation. We had performed laparotomy for reduction of the intussusception. Operative findings revealed ileocolic type of intussusception due to cystic tumor on ileocecal valve that was invaginated into the cecum, and hyperplasia of the Peyer's patch were seen. But we failed manual reduction because of the tumor in the ileocecal area. So we had performed partial resection of the ileocecum. Diverticulum of the ileum was confirmed by pathologic examination. We experienced unusual cause of the intussusception. So we report this case with a review of the literatures.

Kallmann's syndrome is defined as the combination of hypogonadotropic hypogonadism and anosmia/hyposmia. The syndrome is a result of defect in the embryonic migratory pathway of gonadotropin-releasing hormone, which synthesizes neurons and olfactory axons. The hypogonadotropic hypogonadism results due to absence of or incomplete pubertal development and may be associated with anosmia, hyposmia, midline defect(color blindness, cleft-lip, cleft-palate, unilateral renal agenesis, sensorineural deafness), cryptorchidism and skeletal anomaly. Till date in Korea, few cases of Kallmann's syndrome have been reported but there are no available reports on cases of Kallmann's syndrome with unilateral renal aplasia and diabetes mellitus. We handled a case of Kallmann's syndrome associated with unilateral renal agenesis and diabetes mellitus. In the current work, we present a peculiar case as afore mentioned with the review of related literature.

Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by inappropriate myocardial hypertrophy that occurred in the absence of an obvious cause for the hypertrophy and dynamic left ventricular outflow tract obstruction, caused by asymmetrical septal hypertrophy and systolic anterior motion of the anterior mitral leaflet. The pathophysiological abnormality in HOCM is diastolic dysfunction, abnormal stiffness of the left ventricle with resultant impaired ventricular filling and impaired vasodilator reserve (perhaps related to the thickened and narrowed small intramural coronary arteries found in HOCM). During the early course of this progressive disease, treatment consists of negative inotropic drugs. Surgery has been the only therapeutic option in patients with hypertrophic cardiomyopathy who are resistant to drug treatment and sequential pacemaker therapy. We describe a novel catheter-based technique that may replace surgical myocardial reduction. The technique is interventional infarction of a portion of the interventricular septum by the infusion of alcohol into a selectively catheterized septal artery.

BACKGROUND: Density patterns on mammography have been related to the risk factors for breast cancer in the western countries. High mammographic density appears to confer a 4-fold risk of breast cancer. While the proportion of high-density mammography is higher in Korean women than in Caucasian women, the incidence of breast cancer in Korean women is considerably lower. Therefore, we examined if the mammographic breast density pattern correlates with the risk factors for breast cancer in Korean women. METHODS: In a cross-sectional design, we recruited 1,758 pre- and post-menopause women without prior history of breast cancer and breast surgery who underwent screening mammogram and completed a self-administered questionnaire in 6 general hospitals. On the basis of ACR BI RADS breast composition, four density patterns were classified in caudocranial and mediolateral mammography by a designated radiologist in each hospital. Multiple linear logistic regression was used for statistical analyses. RESULTS: Inter-rater reliability between the initial report and the report made by another blinded radiologist was high (Pearson's co-efficient=0.81). Overall, the age, body mass index, family history of breast cancer, and duration of hormone replacement therapy correlated with the mammographic density patterns. In pre-menopausal women, the high body mass index and parity (=2) were associated with low mammographic density. In post- menopausal women, older age, high body mass index, negative family history of breast cancer, and duration of hormone replacement therapy were associated with low mammographic density. CONCLUSION: Our data showed that the mammographic breast density patterns correlated with risk factors for breast cancer in Korean women. While the proportion of high-density mammography is higher in Korean women, the incidence of breast cancer is lower than in the western population. This maybe dependent on other unknown factors.
