In recent decades, dental erosion has received a considerable amount of attention with a steady increase of the prevalence. However, the awareness of this matter in our society, including dentistry is still lacking. Dental erosion is an irreversible loss of dental hard tissue leading to a complex condition. To prevent detrimental effects, it is important to detect conditions as early as possible and inhibit progression. In children and adolescents, early intervention is more important than in adults. As dental erosion is a multifactorial condition, dentists need to fully understand the phenomena and do systematic oral examination with thorough history taking for early diagnosis. When the main etiological factor is detected, it is necessary to make an effort to eliminate it and stop progression of the lesions with preventive measures. Restorative treatment should not be started unless substance loss reaches a certain level. Once the decision is made for treatment, care must be taken to choose the least invasive method.
Purpose: Childhood obesity can be complicated by hypertension, hyperlipidemia, non-alcoholic fatty liver disease, and diabetes mellitus. The aim of this study was to evaluate the prevalence of obesity and metabolic complications of children and adolescents based on the degree of obesity. Methods: We analyzed the records of 8,880 students who received student health examinations between May 2006 and October 2008 at the Eulji General Hospital. The prevalence of obesity was evaluated by the body mass index and obesity index. A total of 1,076 obese students had blood tests. We analyzed aspartate aminotransferase (AST), alanine aminotransferase (ALT), fasting glucose, total cholesterol, and blood pressure according to the degree of obesity. Results: According to the body mass index, the overall prevalence of obesity was 7.2% (7.8% of male and 6.5% of female students). Based on the obesity index, 12.3% of students (mild: 6.3%, moderate: 5.0%, and severe: 1.0%) were obese. The prevalence of hypercholesterolemia, ALT elevation, and hypertension were increased as a function of the degree of obesity (p<0.05), but hyperglycemia showed no significant differences (p=0.298). The overall prevalence of ALT elevation was 17.7% (mild obese group, 10.4%; moderate obese group, 20.5%; and severe obese group, 46.8%). The prevalence of hypercholesterolemia, hypertension, and hyperglycemia were significantly higher in the elevated ALT group (24.7%, 42.6%, and 5.2%, respectively) compared to the normal ALT group (11.1%, 29.8%, and 2.0%, respectively; p<0.05). Conclusion: Hypercholesterolemia, liver function test abnormalities, and hypertension were associated with the degree of obesity. We should focus our attention on managing obese children and adolescents to prevent metabolic complications.
To examine the cause of acute diarrheal disease in children and adolescents, 521 fecal samples underwent multiple-PCR for a period of two years, between March 2015 and February 20178, in the Jeju region of Korea. Based on the analysis of 179 positive samples, 102 samples were male (56.98%) and 77 were female (43.02%), and highest positive rates were shown in the age group of 3~4 years (51.96%) and 5~6 years (12.29%). When 209 cases (40.12%), including double infection were analyzed, there were 88 cases (16.89%) of norovirus-GII infection, 26 cases (4.99%) of Campylobacter spp. infection, 18 cases (3.45%) of rotavirus infection, 18 cases (3.45%) of Clostridium difficile Toxin B infection, 17 cases (3.26%) of adenovirus infection, 16 cases (3.07%) of Clostridium perfringens infection, 11 cases (2.11%) of astrovirus infection, 5 cases (0.96%) of Salmonella spp. infection, 3 cases (0.58%) of norovirus-GI, Yersinia spp. and Aeromonas spp. infections, and 1 case (0.19%) of verocytotoxin-producing E. coli infection. Based on a seasonal separation of early childhood, norovirus-GI and norovirus-GII mainly prevailed during the winter, when the temperature is low. Typical enteritis with an increased prevalence of rotavirus during the spring. Astrovirus prevailed between the months of April and October, when norovirus-GI, norovirus-GII, and rotavirus did not prevail. With increasing age, acute diarrheal disease was not only induced by a virus, but also by bacteria. Although a test for virus is an effective method when trying to identify the cause during early childhood by multiplex-PCR, it would be desirable to undergo tests for both virus and bacteria concurrently as age increases.

Objectives : The aim of the study was to investigate the prevalence by gender and to evaluate associations of depression, anxiety and sleep disturbances in a large sample of adolescents from the general population. Methods : 1422 subjects, aged 14 years students were recruited in the seven middle-school of the local community. The self-report questionnaire(Children's Depression Inventory : CDI, Beck Anxiety Inventory : BAI and Pittsburgh Sleep Quality Index : PSQI) was used for screening depression, anxiety and sleep disturbances in adolescent. CDI, BAI, and PSQI score was categorized into the following quartiles : $\leq$21, 22-25, 26-28, and $\geq$29 ; $\leq$21, 22-26, 27-31, and $\geq$32 ; $\geq$5, <5. The cut-off score is that CDI is 22, BAI is 22 and PSQI is 5. The result was analyzed using the independent t-test, the chi-square test and logistic regression analyses. Results : The mean CDI score($12.52{\pm}8.32$ vs. $10.39{\pm}7.52$ ; p=0.003), BAI($7.77{\pm}7.93$ vs. $9.84{\pm}9.04$ ; p<0.001) and PSQI($4.57{\pm}2.67$ vs. $3.64{\pm}2.30$ ; p=0.013) of girls were significantly higher than for boys. But, boys in the fourth quartile of CDI(CDI$\geq$29) and BAI(BAI$\geq$32) were at significantly elevated risk for sleep disturbances more than for girls after adjustment for sex, history of psychiatric treatment(CDI odd ratio, 14.66 ; 95% CI, 4.17-51.53, BAI odd ratio, 32.99 ; 95% CI, 4.26-255.39). Conclusion : The results suggest that high CDI, BAI score appears to increase the risk for developing sleep disturbances in boys more than girls.

Myoepithelioma is a rare disease in the salivary gland. Myoepithelioma is more common in adults than in children or adolescents. An 8-years-old female patient visited our clinic with a chief complaint of a painless swelling on the palate. Conservative treatment that preserves the overlaying palatal mucosa while surgically excising the tumor was carried out under general anesthesia, because the patient was young and the size of the tumor was relatively large. The surgical wound healed well and there had not been any sign of recurrence during the regular follow-up period of 40 months. Minimally invasive surgical treatment which preserves peripheral palatal tissue can be useful in a pediatric myoepithelioma.
Purpose : To assess the prevalence and characteristics of headache comorbidity with epilepsy in children and adolescents in a specialty epilepsy clinic. Methods : Two hundred twenty nine consecutive patients attending the Chosun University Hospital Pediatric Epilepsy Clinic (mean age $10.0{\pm}4.1\;years$, range 4-17, M:F ratio 1.1:1.0) were interviewed with a standardized headache questionnaire. Headache was classified according to the International Classification of Headache Disorders, 2nd Edition and epilepsy was classified according to the International League Against Epilepsy. Disability was assessed using pediatric migraine disability assessment (PedMIDAS). Results : Of the 229 epilepsy patients, 86 (37.6%) had co-morbid headache. Of the headache patients, 64 (74.4%) had migraine (65.6%- migraine without aura, 20.3% - migraine with aura, 14.1% - probable migraine). The mean headache frequency was $7.2{\pm}8.4$ per month, mean duration was $2.2{\pm}4.0$ hours, mean severity was $5.2{\pm}2.2$ out of 10, and mean PedMIDAS score was $13.0{\pm}35.4$. The proportion of females was not higher in epilepsy with headache patients (48.8%) compared to epilepsy patients alone (48.0%). In the patients with migraine, 48.4% had complex partial seizures, 17.2% had simple partial seizures, and 34.4% had generalized seizures (P=0.368). A postictal association of migraine was reported in 18.8% with 17.2% reporting a preictal headache, and 7.8% reporting an ictal headache. Conclusion : The prevalence of headache in pediatric epilepsy is higher than that in general pediatric population, suggesting a co-morbidity of headache in epilepsy patients with migraine being the most frequent headache disorder. Altered cerebral excitability resulting in an increased occurrence of spreading depression may explain the headache comorbidity with epilepsy. Further studies are needed to assess the etiology of this co-morbidity as well as assess the frequency, duration, severity and disability response to antiepileptic drugs.
Purpose: The purpose of this study was to evaluate the food insecurity status and dietary behavior and examine the association between the food insecurity status and consumption of processed beverage for secondary school students in Vientiane, capital city of Lao PDR. Methods: The study subjects are 714 students (boys = 307 and girls = 407) in four secondary schools (Chao_Anouvong, Phiavat, Saysetha, and Chansavang) of Vientiane, Lao PDR. Data on study subject's demographic characteristics, dietary behavior, food insecurity, and Mini Dietary Assessment (MDA) index were collected. A "Self-Administered Food Security Survey Module for Children Aged 12 Years and Older" developed by the United States Department of Agriculture (USDA) was used for the food insecurity assessment. Results: As a result, 72.7% of the subjects were in a state of food insecurity, and food security was associated with higher socioeconomic status (higher life satisfaction, higher parent's education attainment, higher item ownership, fewer number of siblings, and having more lunches at the school restaurant than at home). Compared to the food insecurity group, the frequency of breakfast, self-rated diet, and the total score of MDA index were higher in the food security group. On the other hand, multiple logistic regression analysis showed that 'food security' was also associated with a higher consumption of processed beverages (OR 1.544; 95% CI 1.078-2.213; p = 0.018). Conclusion: Improving the quality of the diet is essential for adolescents in both the food insecurity and food security groups in Lao PDR. Therefore, it is necessary to provide well organized nutrition education and establish adequate nutrition policy for adolescents in Lao PDR.

This study investigated the descriptive statistics and correlation among self-identity, school violence experience, and family social capital of adolescents and examined influence of school violence experience on self-identity and moderating effect of family social capital on the relationship between school violence experience and self-identity. Data used for analysis was from 7th grade students in The Korean Children and Youth Panel Survey in 2012. Analyses were performed using the IBM SPSS program for demographic analysis, pearson correlation, and stepwise regression analyses. Results of the study were as follows: First, the average was slightly higher for self-identity, parents' affectionate attention, and awareness of their child's friends; the average was lower for misconduct experience and victimization experience; second, there was a weak negative correlation between self-identity and bully victimization; there was a positive correlation between self-identity and family social capital (parents' affectionate attention and awareness of their child's friends). Third, to investigate the effect of school violence experience (bullying and bully victimization) on self-identity, stepwise regression analysis results were as follows: Bullying had a statistically positive influence on self-identity and bully victimization had a statistically negative influence on self-identity; both parents' affectionate attention and awareness of their child's friends had a statistically positive influence on self-identity; fourth, parents' affectionate attention had a statistically negative moderating effect on the self-identity; therefore, it signifies that the relationship between bully victimization and self-identity appears differently depending on the parents' affectionate attention, which means that the parents' affectionate attention had a negative effect on the self-identity of the adolescents who were victimized by school violence.
Purpose : This study investigated the clinical significance of AN in children and adolescents with obesity induced metabolic complications. Methods : Forty-nine patients who had obesity induced metabolic complications were participated in this cross-sectional study. Obesity induced metabolic complications are as follows: hypertension, dyslipidemia, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), nonalcoholic steatohepatitis (NASH), homeostasis model assessment of insulin resistance (HOMA-IR)>3.16. Clinical characteristics, such as, age, percentage-weight-for-height (PWH), pubertal status, blood pressure (BP), fasting plasma insulin level, fasting and post-oral glucose tolerance test 2-hour glucose levels, liver function test, lipid profile, HOMA-IR were compared according to the presence of AN. Results : Sixty-five percent of patients had AN, 57.1% NASH, 57.1% dyslipidemia, 55.1% hypertension, 46.9% IFG, 24.5% HOMA-IR>3.16 and 16.2% IGT. The patients who were moderately to severely obese with AN had higher incidence of IGT and HOMA-IR>3.16. The patients with AN had significantly higher diastolic BP ($79.4{\pm}6.9$ vs $75.4{\pm}5.6mmHg$), fasting levels of plasma insulin ($10.6{\pm}6.0$ vs $6.2{\pm}5.4{\mu}IU/mL$), HOMA-IR index ($2.6{\pm}1.4$ vs $1.4{\pm}1.3$) and PWH ($42.4{\pm}13.0$ vs $34.3{\pm}1.8%$). The increasing tendency for the presence of AN was significantly related to the cumulative number of obesity induced metabolic complications. Binary logistic regression analysis revealed that the presence of AN was significantly associated with fasting plasma insulin level, PWH and IFG. Conclusion : AN could be useful as a clinical surrogate of obesity induced metabolic complications.

Objectives : This study was done to figure out the incidence of Korean adolescents with gender identity problem and homosexual tendency. Self esteem and sexual liberality were also checked to evaluate the relation with these problems. Method : Subjects were 1,748 adolescents (359 middle school boys, 452 middle school girls, 483 high school boys, and 454 high school girls). DSM-IV-TR gender identity disorder criteria, Kinsey's sexual orientation scale, Hudson's short form sexual liberality scale, and Halter's Self-perception profile for children were applied to them. Result : 1) $15\%$ of the middle school boys, $16.7\%$ of the high school boys, $39.4\%$ of the middle school girls, and $40.5\%$ high school girls showed gender identity problem. Incidence of mild problem was more frequent in girls, however severe problem that suggested gender identity disorder was more frequent in boys, especially in high school boys. 2) Gender identity problem group showed lower self esteem than no problem group, especially in the middle school boys (p=0.033) and high school girls (p=0.020). 3) $17\%$ of the middle school boys, $5.4\%$ of the high school boys, $17.7\%$ of the middle school girls, and $12\%$ of the high school girls showed homosexual tendency. The order of more vivid homosexual orientation incidence was as follows ; $3.3\%$ in the middle school girls, $3.1\%$ in the middle school boys, $2.1\%$ in the high school girls, and $1.7\%$ in the high school boys. 4) There was no difference in the score of sexual liberality according to homosexual tendency. In high school girl, self esteem score was lower in homosexual tendency group than that of heterosexual group (p=0.039). 5) Gender identity problem group showed higher incidence of homosexual tendency than that of gender identity formation group (p=0.001). 6) The incidence of sexual identity problem was not changed by age, but homosexual tendency was decreased with age, especially in boys. Conclusion : Adolescents with gender identity problem or homosexual tendency showed low self esteem. Therefore, more attention on systemic evaluation for early detection in school based mental health and psychiatric management for them are needed.
