Purpose: The importance of the neurodevelopmental outcomes of very-low-birth-weight (VLBW) infants has been emphasized as their mortality rate has markedly improved. This study aimed to assess the validity of the Korean Developmental Screening Test (K-DST), a developmental screening tool approved by the Korean Society of Pediatrics, for the timely diagnosis of neurodevelopmental delay in VLBW infants. Methods: Subjects included VLBW infants enrolled in the Korean Neonatal Network database between January 2012 and December 2014. The collected data were analyzed for sensitivity, specificity, positive predictive value, and negative predictive value (NPV) in the K-DST compared to those in the Bayley Scales of Infant Development-II for VLBW infants. Results: A total of 173 patients were enrolled. Their mean gestational age and mean birth weight were $27.5{\pm}2.8weeks$ and $980.5{\pm}272.1g$, respectively. The frequency of failed psychomotor developmental index (PDI) <85 was similar to that in at least one domain of K-DST <1 standard deviation. Failure in more than one K-DST domain compared with a mental developmental index (MDI) <85 showed a sensitivity and NPV of 73.2% and 75.0%, respectively. Failure in more than one K-DST domain compared with PDI <85 showed a sensitivity and NPV of 60.3% and 71.6%, respectively. Each K-DST domain had a stronger correlation with predicting a failing MDI <85 than a failing PDI <85 (P<0.05). Conclusion: K-DST could be a useful screening tool for predicting mental developmental delay in VLBW infants and referring them for neurodevelopmental assessments.

Post-hemorrhagic hydrocephalus (PHH) in preterm infant is common, life-threatening and the main cause of bad developmental outcomes. Ventriculoperitoneal (VP) shunt is used as the ultimate treatment for PHH. Low birth weight and low gestational age are the combination of worse prognostic factors while the single most important prognostic factor of VP shunting is age. Aggressive and early intervention have better effect in intraventricular hemorrhage and intracranial pressures control. It reduces infection rate and brain damage resulted in delayed shunt insertion. It is extremely important to let PHH infants get older and gain weight to have internal organs to be matured before undergoing VP shunt. As premature infants undergo shunt after further growth, shunt-related complications would be reduced. So temporary surgical intervention is critical for PHH infants to have them enough time until permanently shunted.

A study for the supplementary diet of the infants and young children of the farming area in Korea has been made. The number of infants and children was 344 aged from 3 months to 2 years and 7 months: the area studied represented one of the stabilized farming areas in this country. 95.6 per cent of the infants were breastfeeding babies, who could not supply any milk products or appropriate supplementary diets. For the improvement of nutritional states of the babies, regional childcare guidance was more urgently needed than social economical problems of this area.

Background: Most developmental screening tools in Korea are adopted from foreign tests. To ensure efficient screening of infants and children in Korea, a nationwide screening tool with high reliability and validity is needed. Purpose: This study aimed to independently develop, standardize, and validate the Korean Developmental Screening Test for Infants and Children (K-DST) for screening infants and children for neurodevelopmental disorders in Korea. Methods: The standardization and validation conducted in 2012-2014 of 3,284 subjects (4-71 months of age) resulted in the first edition of the K-DST. The restandardization and revalidation performed in 2015-2016 of 3.06 million attendees of the National Health Screening Program for Infants and Children resulted in the revised K-DST. We analyzed inter-item consistency and test-retest reliability for the reliability analysis. Regarding the validation of K-DST, we examined the construct validity, sensitivity and specificity, receiver operating characteristic curve analysis, and a criterion-related validity analysis. Results: We ultimately selected 8 questions in 6 developmental domains. For most age groups and each domain, internal consistency was 0.73-0.93 and test-retest reliability was 0.77-0.88. The revised K-DST had high discriminatory ability with a sensitivity of 0.833 and specificity of 0.979. The test supported construct validity by distinguishing between normal and neurodevelopmentally delayed groups. The language and cognition domain of the revised K-DST was highly correlated with the K-Bayley Scales of Infant Development-II's Mental Age Quotient (r=0.766, 0.739), while the gross and fine motor domains were highly correlated with Motor Age Quotient (r=0.695, 0.668), respectively. The Verbal Intelligence Quotient of Korean Wechsler Preschool and Primary Scales of Intelligence was highly correlated with the K-DST cognition and language domains (r=0.701, 0.770), as was the performance intelligence quotient with the fine motor domain (r=0.700). Conclusion: The K-DST is reliable and valid, suggesting its good potential as an effective screening tool for infants and children with neurodevelopmental disorders in Korea.

The natural resources of Jeju are recognized as the new regional image of that clean island. Reflecting these trends, this study is initiated to develop a textile design with the motive of persimmon, a natural resource of Jeju, and to apply it to infant's and children's clothes. Its purpose is to highlight the image of persimmon, a traditional dye, as a regional signature for Jeju. Product development procedure included, understanding the use of persimmon for fashion products, analyzing Infants' and Children's designer collections over the last three seasons (focused on 2014S/S, 2015S/S, and 2016S/S), and surveying the Children's Clothes market for persimmon dyeing in Jeju. The conclusion was that, the natural resources of Jeju are highly valuable, and should be applied to textile design and apparel products for children. Utilizing Jeju persimmon was actively studied, but, the market for the Jeju persimmon natural - dyeing products is extremely limited. Moreover, the apparel products for infants and children represent old-fashioned styles, despite their higher prices. Therefore, using the formative characteristics of persimmon for each theme was suggested for development of patterns for textile design. Pattern designs were expressed using textured textile screen-printing, embroidery and $appliqu{\acute{e}}$ for infants' and children's clothes. In this study, a total of 10 items were prepared as apparel products for infants and children. All items were designed considering mix-and-match, potential, with each other or with regular mass-market products. These results are expected to contribute to highlighting the unique image of Jeju and to help promote fashion culture products.

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?

In infants and small children, ultrasound (US) guidance provides ample anatomical information to perform neuraxial blocks. We can measure the distance from the skin to the epidural space in the US image and can refer to it during needle insertion. We may also visualize the needle or a catheter during real-time US-guided epidural catheterization. In cases where direct needle or catheter visualization is difficult, US allows predicting successful puncture and catheterization using surrogate markers, such as dura mater displacement, epidural space widening due to drug injection, or mass movement of the drug within the caudal space. Although many experienced anesthesiologists still prefer to use conventional techniques, prospective randomized controlled trials using US guidance are providing increasing evidence of its advantages. The use of US-guided regional block will gradually become widespread in infants and children.

The clinical characteristics of fistula-in-ano in infants are different from those of older children, and its treatment remains controversial. We suggest that fistula-in-ano in infants has a congenital etiology. To verify this hypothesis and to settle the controversies regarding fistula-in ano in infants, a retrospective analysis of 29 patients less than 2 years of age with anal fistulae treated between 1994 and 2009 at Samsung Changwon Hospital were reviewed retrospectively. Twenty two patients were male and mean age at diagnosis was $7.2{\pm}5.2$ months. Eleven out of 22 cases had previous surgical drainage for perianal abscess. 18 patients had fistulotomy (81.8 %) and four had fistulectomy (18.2 %). Cryptotomies with fistulectomy were performed in 10 patients (45.5 %) who had involved crypt. There was one recurrence. These results suggest that fistula-in-ano in young children less than two years of age is different from those in older children or adults. Fistulotomy is suggested to be the recommended treatment of choice. A future study involving non-operative management would be required to explore all treatment options.

Background: Major questions remain regarding the agestratified trends of allergic diseases and asthma in Korea. Purpose: To identify the estimated recent prevalence and 10-year trends in asthma, allergic rhinitis, and atopic dermatitis among the Korean population from 2008 to 2017. Methods: This nationwide cross-sectional survey (Korean National Health and Nutrition Examination Survey) over 10 years (2008-2017) examined representative samples of the Korean population (n=85,006) including 2,131 infants, 4,352 preschool children, 12,919 school-age children, 44,200 adults, and 21,404 elderly adults. Results: In the 2016 to 2017 population, the estimated prevalence of asthma was 0.9% in infants, 2.3% in preschool children, 4.1% in school-age children, 2.3% in adults, and 4.1% in the elderly. The estimated prevalence of allergic rhinitis was 9.0%, 20.2%, 27.6%, 17.1%, and 6.9%, respectively. The estimated prevalence of atopic dermatitis was 5.9%, 11.3%, 14.6%, 3.9%, and 1.6%, respectively. Ten-year trends revealed a significant decrease in asthma prevalence in infants, preschool children, and the elderly. and in atopic dermatitis prevalence in infants and preschool children (P<0.05 for all trends). Furthermore, 10-year trends demonstrated a significant increase in allergic rhinitis prevalence in school-age children, adults, and the elderly, and in atopic dermatitis prevalence in school-age children and the elderly (P<0.05 for all trends). Conclusion: These results improve our understanding of the age-stratified epidemiology of allergic diseases in Korea and suggest the need for the development of tailored and precise strategies to prevent allergic diseases in different age groups.
