This study examined the impact of childhood physical abuse on the self-concept of older adolescents and assessed perceptions of parental relationships as a mediator for consequences of abuse. Sixty-college undergraduates (aged 18-23 yrs.) completed this study. (1) The Self-Description Questionnaires, a multidimensional measure of self-concept, (2) the parent scales of the inventory parent and Peer Attachment, a measure of perceived parental support, and (3) the Assessing Environments, a retrospective report of family environment and parenting practices. Analyses, controlling for SES and education, showed that a history of physical abuse was a strong predictive of adolescence current self-concept. Further analyses would lend support to a mediation model, suggesting that physical abuse had a negative impact on self-concept through its negative effect on parent-child relationships.

Gastroesophageal reflux (GER) defined as passage of gastric contents into the esophagus without symptoms is a common physiologic gastrointestinal problem in infants, children and even in adults. But gastroesophageal reflux disease (GERD) defined as symptoms or complications of GER is a disease entity to find out the reason and treat. After the era of 1970 we have been studying about GERD with the development of diagnostic and therapeutic methods. I already introduced the nature and the fundamental knowledge of GERD in the opening symposium of KSPGHAN in 1998. Now, I will introduce the guidelines for evaluation and treatment of GERD which was recommended by the North American Society for Pediatric Gastroenterology and Nutrition and American Pediatric Association which was published in 2001. And I will introduce progressing subjects and the forecoming issues to be solved in near future. Those are as followings. Does GERD cause otolaryngologic symptoms such as chronic sinusitis and chronic otitis? Is GERD inherited? Can we find out the child who will become GERD in adult life and the way to reduce the incidence of Barrett's esophagus and esophageal cancer? Is long term PPI therapy safe in children?

Helicobacter pylori plays an important role in the pathogenesis of chronic gastritis, peptic ulcer disease, gastric cancer, and gastric mucosa-associated lymphoid tissue lymphoma. In Korea, the guidelines for the diagnosis and treatment of H. pylori infection in adults were revised in 2013. The European Helicobacter and Microbiota Study Group and Consensus panel released the fifth edition of the Maastricht Consensus Report for the management of H. pylori infection in 2015, and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition and the North American Society of Paediatric Gastroenterology, Hepatology and Nutrition released the updated joint guidelines for children and adolescents in 2016. Considering these recommendations and recent progress in our research and that of other research teams, this study aimed to discuss the diagnostic strategies for H. pylori infection in children and adolescents.

The purpose of this study was to determine composition of food groups appropriate for the evaluation of the quality of total diet or food guide, using the data from the 1998 National Health and Nutrition Survey. Twenty-four-hour-dietary recalls of total 1,110 Korean adolescents aged 13 - 19 years (male 543, female 567) were analyzed for food group consumed (Dietary Diversity Score, DDS), intake patterns of food group, mean index of nutritional quality (mINQ) and nutrient adequacy ratio (NAR). Considering Korean food pattern different from the Americans, this study is to check if Korean 5 food groups with both of oil & sugar group and vegetable & fruit group, and a minimum amount of 30 g in grain group and 15 g in meat group modified from Kant's minimum amount, 15 g in grain and 30 g in meat, could also be appropriate for the diet evaluation of Korean adolescents. Combination of food group and minimum food intake per each food group used in the first trial were categorized into 6 kinds of types: 1) American 5 food groups with Kant's minimum amount as control or 2) American 5 food groups with modified Kant's minimum amount 3) Korean 5 food groups excluded by sugar with the modified amount 4) Korean 5 food groups with modified amount 5) American food groups added oil group with the modified amount 6) American food groups added oil & sugar group with the modified amount. In case of oil group or oil and sugar group, 5 g was quoted for the minimum amount. Correlation between DDS and indices of other diet quality in each type of food group composition were analyzed and the best food group composition was traced by comparing the correlation coefficients of DDS and mINQ or MARs at ${\alpha}\;<\;0.01$. There was no meaningful difference in weight length index of the subjects of eating or not-eating oil or oil & sugar, while the values of mINQ showed higher in the subjects eating oil but no difference in the subjects eating oil & sugar, compared to the group not-eating, respectively. In comparison of type 1 and type 2, correlation between DDS and indices of other diet quality showed higher in type 1 using Kant's amount. And comparing the type of a combined group of fruit & vegetable (type 3 and 4) and the type of separated group of fruit and vegetable (type 5 and 6). six groups of separated vegetable and fruit showed the higher correlation of DDSs and indices of diet quality. In case of being classified into six groups with oil, DDS showed correlation of r = 0.293 with INQ. While, being classified into six groups with oil & sugar instead of oil only, DDS showed correlation of r = 0.249 with INQ. Accordingly the type 5 with oil is regarded as the better food group type than the type 6 with oil & sugar. Since better result was shown in the composition of six groups with Kant's minimum amount, the comparative analysis on both of type1 with oil and oil & sugar was finally performed. Then oil added type 1 showed higher correlation of DDS and indices of diet quality. These result indicated that it would be more appropriate to use six food groups with separate vegetable and fruit including oil group (oil-added type 1) rather than oil & sugar group for evaluation of dietary quality of Korean adolescents using DDS.

Calcium intake has been insufficient in all age groups in previous Korean national surveys. This study was conducted to investigate calcium intake in Korean and American populations at different ages. We analyzed two national survey data: the 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES) and the 2007~2008 National Health and Nutrition Examination Survey (NHANES). Statistically, survey procedures were applied using the weight, cluster, and strata variables. The mean calcium intake of Koreans at ages of 1~2 y, 3~5 y, 6~11 y, 12~18 y, 19~64 y, and 65+y was lower than American populations at those ages. The sufficient proportions based on Korean Estimated Average Requirement (EAR) of 1~2 y, 3~5 y, 6~11 y, 12~18 y, 19~64 y, and 65+y in Koreans were 45.5%, 33.1%, 24.3%, 16.6%, 32.7%, and 19.0%. While the sufficient rates based on American EAR of 1~3 y, 4~8 y, 9~13 y, 14~18 y, 19~30 y, 31~50 y, 51~70 y, and 71+y in US population were 88.5%, 54.4%, 35.2%, 35.8%, 55.3%, 55.2%, 40.6%, and 24.5%. Overall, the major foods contributing to calcium intakes in Koreans were milk, baechukimchi, and anchovies, whereas, milk products, pasta, or bread were major contributions to calcium in American populations. The calcium supplement intakes in the American population were 5.5 mg (1~2 y), 15.5 mg (3~5 y), 13.9 mg (6~11 y), 35.7 mg (12~18 y), 150.3 mg (19~64 y) and 334.4 mg (${\geq}65$ y). These results suggest that Korean adolescents and older adults are the most insufficient in dietary calcium intakes among Koreans. In order to accurately estimate calcium intakes in Korean populations, calcium supplements and calcium-fortified foods should be considered.

Purpose: The purpose of this study is to understand a variety of intervention studies to prevent smoking by adolescents in U.S. and find out implications for Korea. Methods: This study reviewed articles found in the internet and analysed the data of US DHHS and CDC. Results: The School Health Policies and Programs Study (SHPPS) is a national survey periodically conducted to assess school health policies and programs of U.S. The main components of SHPPS are health education and physical education, health services, mental health and social services, school policies, and school environments. The CDC guidelines for school health programs to prevent tobacco use and addiction are composed of policy, instruction, curriculum, training, family involvement, tobacco-use cessation efforts, and evaluation. School-based interventions to prevent smoking can be classified into the categories of information-giving curricula, social competence curricula, social influence approaches, combined methods draw on social competence and social influence approaches and multi-modal programmes and Youth Empowerment study. The key programs for adolescent smoking prevention are ALERT Project, HSPP, TNT Project, MPP, NC YES. Conclusions: As smoking is often the first step of unhealthy behaviour such as alcohol drinking, illegal drugs, and violence, smoking prevention programmes for adolescents in U.S. have been comprehensive school-based health programs. In smoking prevention programs for adolescents, CDC plays a critical role by supporting survey, research, policy, and funds. The effectiveness of the programs was high when it was based on school and involved parents, community, and mass media. As the effect of each programme is not expected to last for a long time, consistent repetition of these interventions is essential. Current smoking prevention programs for adolescents are exploring the empowerment approach focused on the active involvement of participants rather than traditional approaches using order and discipline.

Background and Objectives Respiratory scoring guidelines for children and adults have been used for evaluating adolescents both in the 2007 and 2012 American Academy of Sleep Medicine (AASM) scoring manuals. We compared the scoring methods of polysomnography used in these scoring manuals, where pediatric and adult scoring rules were adopted for the diagnosis of sleep apnea in adolescents. Subjects and Method 106 Korean subjects aged between 13 and 18 years were enrolled. All subjects underwent overnight polysomnography in a sleep laboratory. Data were scored according to both pediatric and adult guidelines in the 2007 and 2012 AASM scoring manuals. Results Both pediatric and adult apnea hypopnea index (AHI) using the 2012 method were significantly higher than those using the 2007 method. The difference in AHI compared between pediatric and adult scores with the 2012 AASM scoring system was markedly decreased from that with the 2007 method. There was a significant discordance in sleep apnea diagnosis between pediatric and adult scoring rules in the 2012 method. Conclusion Both pediatric and adult rules were used for the diagnosis of adolescent sleep apnea in the 2012 method. However, there was significant discordance in the diagnosis between pediatric and adult scoring guidelines in the 2012 AASM manual, probably due to different cut-off values of AHI for the diagnosis of sleep apnea in pediatric (${\geq}1$) and adult (${\geq}5$) patients. Further studies are needed to determine a more reasonable cut-off value for the diagnosis of sleep apnea in adolescents.

Purpose: The aim of this study is to evaluate the effectiveness of surgical treatment in adolescent patients suffering from navicular stress fracture. Materials and Methods: A total of 11 adolescent patients aged 14 to 19, who underwent an operation for navicular stress fracture between 2005 and 2008 were recruited. Clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and visual analogue scale (VAS) score. Results: The mean VAS score before the operation was 7.7. A score of 2.9 was confirmed at final follow up after the operation. The mean final follow-up period was 22.1 months. There was a statistically significant improvement in the VAS score between before and after the operation (p=0.01), and similarly, the AOFAS score also showed an improvement, from 46.5 to 80.7 (p=0.01). The pain that remained after the operation, according to the VAS score, was severe in three patients (27.3%), tolerable in seven patients (63.6%), and free of pain in one patient (9.1%). Conclusion: In navicular stress fracture in adolescents, careful selection of patients who could benefit from surgical treatment is recommended.

페닐케톤뇨증(PKU)은 전세계적으로 가장 잘 알려지고 중요한 유전성 대사질환이다. 1950년대 이후 단백제한을 이용한 식사치료를 처음으로 시도하여 성과가 있었던 질환이며 1960년대 이후 신생아선별검사를 통해 조기진단과 조기치료가 가능하게 된 최초의 유전성대사질환이기 때문이다. 단백제한 식사치료의 효과가 좋지만 학동기, 사춘기 이후 성인시기까지 유지하는 것의 어려움이 있고 이시기에 조절이 잘 되지 않았을 경우 경련, 여러가지 정신과적인 문제들, 삶의 질의 감소 등이 문제가 되어서 오랜 기간 치료를 위한 여러 방법들이 제시되었다. 더해서 2014년 미국의학유전학회(American Medical College of Medical Genetics and Genomics, ACMG)에서 전 연령에서 혈중 페닐알라닌 수치를 120-360 umol/L로 제시를 한 이후 더욱 치료의 중요성이 올라갔다. 2000년대 페닐알라닌수산화 효소(phenylalanine hydroxylase, PAH)의 조효소인 tetrahydrobiopterin (BH4)가 치료 승인되어서 약물반응을 보이는 환자에서 치료가 시작되었으며 4세미만에서도 허가가 되어서 이른 시기부터 약물치료를 병행하여 효과를 보게 되었다. 높은 혈중 페닐알라닌수치가 혈액-뇌 장벽(Blood-brain barrier, BBB)을 통하여 뇌로 넘어가서 회백질의 변성을 나타내게 되는 문제를 막기 위해 거대중성아미노산(LNAA)를 이용한 치료가 시도되고 있다. 오랫동안 연구되었던 페닐알라닌을 trans-cinnamic acid와 암모니아로 변화를 시키는 phenylalanine ammonialyase (PAL)을 이용한 효소치료는 최근 약제로 개발되어서 2018년 이후 성인환자를 대상으로 치료가 시작되었고 잘 조절되지 않는 환자들에게 효과를 보이고 있다. PAL을 경구용으로 개발하는 것이 빠르게 진행 중이며 유전자치료에 대한 연구들도 활발하게 진행이 되고 있어 다양한 치료들이 앞으로 기대된다.
