Purpose: Neurocardiogenic syncope (NCS) is the most frequent cause of fainting during adolescence. Inappropriate cardiovascular autonomic control may be responsible for this clinical event. The head-up tilt test has been considered a diagnostic standard, but it is cumbersome and has a high false-positive rate. We performed a study to evaluate whether P-wave dispersion (PWD) could be a useful electrocardiographic parameter of cardiac autonomic dysfunction in children with NCS. Methods: Fifty-four patients with NCS (28 boys and 26 girls; mean age, $12.3{\pm}1.4$ years) and 55 age- and sex-matched healthy controls were enrolled. PWD was obtained as the difference between maximum and minimum durations of the P wave on standard 12-lead electrocardiography in all patients and controls Results: The value of PWD was significantly higher in the syncope group than in the control group ($69.7{\pm}19.6$ msec vs. $45.5{\pm}17.1$ msec, respectively; P<0.001). The minimum duration of P wave was shorter in the syncope group than in the control group ($43.8{\pm}16.8$ msec vs. $53.5{\pm}10.7$ msec, respectively; P<0.001). Left atrial volume was not different between the groups on transthoracic echocardiography. Conclusion: PWD on echocardiography could be used as a clinical parameter in patients with NCS.

Objectives : The somatization is various physical symptoms that have no pathologic manifestation. It is very common to Korean children and adolescents as well as adults, because cultural background and immature verbal expression. DSM-Ⅳ(Diagnostic and Statistical Manual of Mental Disorders Fourth Edition) presented diagnostic criteria for Somatization disorder by grouping some symptoms out of somatization. This report is on a case of somatization disorder patient. The patient is 13-year-old female. She has been suffered from various physical symptoms those are coincided with diagnostic criteria for Somatization disorder by DSM-Ⅳ. Methods : The authors treated her by acupuncture and 3 kinds of herb medicine-Bunsimgium, Hyungbangdojuksan, Yangguksanwhatang. Results : Bunsimgium was showed a little improvement but could not solved chief complaint. Hyungbangdojuksan was not given a help. After her taking Yangguksanwhatang, most symptoms were subsided. Conclusions : A patient with the somatization disorder was improved by herbal medication and acupuncture. But the Somatization disorder repeats to take a good turn and a bad turn and continues for long time, so we need to follow up her condition.

Purpose: There is little known about teachers' self-efficacy in health teachers even though over 75% of Korean health teachers have offered school health education. The purpose of this study was to examine factors related to teachers' self-efficacy in Korean health teachers. Methods: Data were collected from school nurses from 474 schools such as 236 elementary schools, 140 middle schools and 98 high schools in Seoul with the stratified random sampling method. The associations among school characteristics, health teachers' characteristics, and teachers' self-efficacy were examined by ANOVA (Anlaysis of variable). To identify the possible predictors of teachers' self-efficacy, ANCOVA (Analysis of covariance) was performed. Results: Two factors, school stage (elementary, middle or high schools) and types of school (public or private school), were significantly related to teachers' self-efficacy. Teachers' self-efficacy of health teachers in elementary schools was significantly higher than that in middle and high schools. Health teachers in private school had significantly higher teaching self-efficacy than ones in public school. Conclusion: Given the fact that health teachers in elementary and private school had higher teachers' self-efficacy, an intervention to strengthen teachers' self-efficacy of health teachers in middle and high schools as well as ones in public school is required to help children and adolescents learn good health behaviors.

Avulsion injuries result from the application of a tensile force to a musculoskeletal unit or ligament. Although injuries tend to occur more commonly in skeletally immature populations due to the weakness of their apophysis, adults may also be subject to avulsion fractures, particularly those with osteoporotic bones. The most common sites of avulsion injuries in adolescents and children are apophyses of the pelvis and knee. In adults, avulsion injuries commonly occur within the tendon due to underlying degeneration or tendinosis. However, any location can be involved in avulsion injuries. Radiography is the first imaging modality to diagnose avulsion injury, although advanced imaging modalities are occasionally required to identify subtle lesions or to fully delineate the extent of the injury. Ultrasonography has a high spatial resolution with a dynamic assessment potential and allows the comparison of a bone avulsion with the opposite side. Computed tomography is more sensitive for depicting a tiny osseous fragment located adjacent to the expected attachment site of a ligament, tendon, or capsule. Moreover, magnetic resonance imaging is the best imaging modality for the evaluation of soft tissue abnormalities, especially the affected muscles, tendons, and ligaments. Acute avulsion injuries usually manifest as avulsed bone fragments. In contrast, chronic injuries can easily mimic other disease processes, such as infections or neoplasms. Therefore, recognizing the vulnerable sites and characteristic imaging features of avulsion fractures would be helpful in ensuring accurate diagnosis and appropriate patient management. To this end, familiarity with musculoskeletal anatomy and mechanism of injury is necessary.

In the past, hepatitis B virus (HBV) infection was endemic in the general Korean population. The association of HBV infection with the occurrence of liver cancer has been well demonstrated in several epidemiologic studies. While the mortality rates of liver cancer in Korea have decreased steadily over the last decade, the presence of hepatitis B surface antigen (HBsAg) in mothers remains high at 3-4%, and 25.5% of these HBsAg positive mothers are positive for hepatitis B e antigen (HBeAg). HBV infection caused almost a quarter of hepatocellular carcinoma (HCC) cases and one-third of deaths from HCC. These aspects of HBV infection prompted the Korean government to create a vaccination program against HBV in the early 1980s. In 1995, the Communicable Disease Prevention Act (CDPA) was reformed, and the government increased the number of HBV vaccines in the National Immunization Program (NIP), driving the vaccination rate up to 95%. In 2000, the National Health Insurance Act (NHIA) was enacted, which provided increased resources for the prevention of perinatal HBV infection. Then in 2002, the Korean government, in conjunction with the Korean Medical Association (KMA), launched an HBV perinatal transmission prevention program. The prevalence of HBsAg in children had been high (4-5%) in the early 1980s, but had dropped to below 1% in 1995, and finally reached 0.2% in 2006 after the NIP had been implemented. After the success of the NIP, Korea finally obtained its first certification of achievement from the Western Pacific Regional Office of the World Health Organization (WPRO-WHO) for reaching its goal for HBV control. An age-period-cohort analysis showed a significant reduction in the liver cancer mortality rate in children and adolescents after the NIP had been implemented. In addition to its vaccination efforts, Korea launched the National Cancer Screening Program (NCSP) for 5 leading sites of cancer, including the liver, in 1999. As a consequence of this program, the 5-year liver cancer survival rate increased from 13.2% (1996-2000) to 23.3% (2003-2008). The development of both the primary and secondary prevention for liver cancer including HBV immunization and cancer screening has been of critical importance.

The rhabdomyosarcoma (RMS) is the most common type of soft tissue tumor in children and adolescents; yet only a few screens for oncogenic mutations have been conducted for RMS. To identify novel mutations and potential therapeutic targets, we conducted a high-throughput Sequenom mass spectrometry-based analysis of 238 known mutations in 19 oncogenes in 17 primary formalin-fixed paraffin-embedded RMS tissue samples and two RMS cell lines. Mutations were detected in 31.6% (6 of 19) of the RMS specimens. Specifically, mutations in the NRAS gene were found in 27.3% (3 of 11) of embryonal RMS cases, while mutations in NRAS, HRAS, and PIK3CA genes were identified in 37.5% (3 of 8) of alveolar RMS (ARMS) cases; moreover, PIK3CA mutations were found in 25% (2 of 8) of ARMS specimens. The results demonstrate that tumor profiling in archival tissue samples is a useful tool for identifying diagnostic markers and potential therapeutic targets and suggests that these HRAS/ PIK3CA mutations play a critical role in the genesis of RMS.
