Ingestion of foreign bodies (FBs) is a common phenomenon among young children. Plain radiography is the first step diagnostic modality to detect the radio-opaque FBs. And computed tomography has been recommended by several guidelines as useful modalities for diagnosing ingested FBs. However, there is a risk of radiation exposure, making it burdensome to use in asymptomatic patients. Ultrasound (US) is not a commonly used technique for diagnosing ingested foreign bodies. However, US can provide real-time imaging with good resolutions without radiation exposure in pediatric patients. Herein, we report two pediatric cases of metallic foreign body ingestion that were successfully diagnosed using US for localizing foreign bodies. This study indicates that US may be used as an alternative method for detecting the localization of metallic foreign bodies in the gastrointestinal tract without exposure of radiation, particularly in pediatric patients.

Objectives: This study was conducted to investigate the boron concentrations in 30 slime products and estimate children's dermal exposure to boron. Methods: Thirty slime products from online and offline stores were purchased for boron analysis. The boron content of each slime sample was analyzed using ICP-OES. A nationwide survey was performed to determine use patterns of slimes by a home-visit survey of 10,000 children divided into three age groups: 0-2, 3-6, and 7-12 years. The dermal exposure to boron was calculated using an exposure algorithm for child slime users. Results: The proportion of the child population using slime was 45.8%, and the mean use frequency was $2.5{\pm}3.8$ per week (range: 0.08-35). Mean time spent playing with slime was $19.6{\pm}11.3min$ (range: 1-100). Twenty-five of the thirty slimes contained a boron concentration exceeding the EU limit for toys made with sticky material of 300 mg/kg. Dermal exposure ranged from $0.0008-13.78{\mu}g/kg/day$ with the maximum weight fractions of boron in the 30 products. The dermal exposure estimate was the highest in 7-12 years old group. Conclusion: Slime use among Korean children may cause high exposure to boron. Regulation is needed to minimize boron exposure from slime products.

목적: 본 연구는 30일 이상 90일 미만의 발열이 있는 영아에서 경험적 항생제 사용에 미치는 요소를 조사하였다. 방법: 2010년 1월부터 2016년 12월까지 부산대학교 어린이병원에 발열이 있는 이전에 건강했던 영아를 대상으로 임상양상, 검사소견, 항생제 사용에 대해 의무기록을 후향적으로 분석하였다. 호흡기 바이러스는 다중 역전사 중합 연쇄반응검사로 검출하여 1-3일 후 보고되었고, enterovirus는 중합 연쇄반응검사로 검출하여 수시간 만에 보고되었다. 결과: 366명의 대상자 중 129명은 경험적 항생제를 사용하였고 237명은 경험적 항생제를 사용하지 않았다. 입원 전 발열기간이 긴 경우와 호흡기 증상이 있을 때, 아파보일 때, CRP 상승 시 경험적 항생제 사용이 많았다. 경험적 항생제를 사용하지 않은 환자의 재입원율이 낮았다. Enterovirus polymerase chain reaction (PCR)이 검출된 대부분의 환자는 경험적 항생제를 사용하지 않았다. Respiratory virus multiplex reverse transcriptase (RT)-PCR 결과는 경험적 항생제 사용에 차이를 보이지 않았다. 결론: 본 연구에서 respiratory virus multiplex RT-PCR은 항생제 처방에 영향을 주지 않았고 enterovirus PCR은 항생제 처방에 영향을 주었다. Respiratory virus multiplex RT-PCR 결과가 신속하게 보고된다면 항생제 사용에 영향을 줄 것이다.

Purpose: Pediatric Crohn's disease (CD) is directly related to growth and has a high probability of requiring surgical intervention(s); therefore, more active treatment for CD is required for children. This study investigated the impact of biologics on growth and disease course associated with surgery. Methods: This was a retrospective cohort study involving patients diagnosed with CD at the Seoul National University Children's Hospital (Seoul, Korea) between January 2006 and October 2017. The aim was to determine the characteristics of pediatric patients with CD and whether biologics affected growth and the surgical disease course. Results: Among patients who underwent surgery for CD, the mean number of operations per patient was 1.89. The mean time from initial diagnosis to surgery was 19.3 months. The most common procedure was fistulectomy (34%), followed by incision and drainage (25%). In all patients, the use of biologics increased the height (p=0.002) and body mass index (BMI) (p=0.005). Among patients who underwent surgery, height (p=0.004) and BMI (p=0.048) were increased in the group using biologics. Patients who used biologics exhibited a low operation rate only within 2 years after diagnosis, with no differences thereafter (p=0.027). Conclusion: Although biologics could not mitigate the operation rate in pediatric patients who underwent surgery for CD, biological therapy delayed disease progression within 2 years of disease onset. Additionally, biologics conferred growth and BMI benefits in this window period. Therefore, it may be helpful to use biologics for optimal growth in pediatric patients with a high probability of undergoing future surgery.

This study examined the effects of paternal smoking on the developmental levels of children younger than 3 years of age. For this purpose, the paper made use of data from the Panel Study on Korean Children which has been released in 3 waves - 2008, 2009, and 2010. The main findings are as follows. First, the smoking characteristics of parents (e.g., the amount of smoking in the morning, the time starting the first cigarette of the day) rather than the duration of smoking or whether the father smoked or not revealed significant relationships with developmental levels. Second, children whose fathers preferred smoking in the morning exhibited lower activity levels or more areas with developmental delays than did their counterparts. Third, children whose fathers smoked more than 11 cigarettes a day were more likely to show problematic developmental levels, especially among those whose fathers responded so only for 1 year out of 3 years. Based on these findings, this study suggests that future research may be conducted, relating to the mechanisms through which morning smoking affects children and possible interventions for such morning smokers.

Objective: The purpose of this study was to investigate grandmothers' verbal and nonverbal behaviors during young grandchildren-grandmother picture book reading. Methods: Participants were fifty-two children aged 22-42 months and their grandmothers. The researcher visited participating children's homes or child care centers and videotaped grandchildren-grandmother book reading activities. Each grandmother read two picture books for each observation. Grandmother surveys were administered after the reading activities. Parent surveys were completed by parents and were returned to the researcher. Results: First, grandmothers began reading picture books to grandchildren when children were 6 to 11-months-old or 12 to 17-months-old. They spent 5 to 10 minutes or 10 to 15 minutes at a time reading books. Second, grandmothers' most frequent verbal behavior during young grandchildren-grandmother picture book reading was 'explaining,' followed by 'questioning,' and 'providing feedback,' in that order. Grandmothers' MLU-eojeol during grandchildren-grandmother reading was 2.56. Their most frequently used nonverbal behavior was 'pointing,' followed by 'gestures.' Lastly, there was a significant difference in grandmothers' verbal and nonverbal behaviors during grandchildren-grandmother reading, depending on the grandmothers' characteristics. Conclusion/Implications: Grandmothers use various verbal and nonverbal behaviors during grandchildren-grandmother picture book reading activities, and there are significant differences in grandmothers' verbal and nonverbal behaviors with grandchildren based on grandmothers' characteristics.

After the WHO Growth Standards (WHOGS) was published in 2006, many countries in the world endorsed and adopted the new growth references as a standard measure for the growth of infants and young children. Certainly, the WHOGS has an impact on the global policy about obesity and underweight in children. Such WHOGS innovation has influenced many regional health authorities and academies, which have managed their own growth charts for a long time, in changing their strategies to develop and use regional growth charts. In Korea, along with the tradition to create a national growth chart every decade, we now face a new era of advancing with the WHOGS.

Objectives : The purpose of this study was to examine the use of dentifrice for children, the state of dentifrice for children on the market and the relationship between the bore of dentifrice and the amount of dentifrice used in an effort to provide parents, main consumers of dentifrice for children, with the right information on dentifrice. Methods : Data on the use of children's dentifrice were gathered by investigating parents in Seoul and Gyeonggi Province in July and August, 2009. The selected parents had children aged one to five in Western age. Results : 1. As to the purchase of dentifrice for children, the largest group (75.9%) were aware of the name of the toothbrush used by their children, and the greatest group (97.3%) bought the toothbrush on behalf of them. Advertising was the most dominant source of information on the choice of dentifrice (51.8%), and non-professionals were the most common providers of information on that (55.9%). 2. The amount of dentifrice used at a time was a mean of $0.467{\pm}0.270g$. There was a wide disparity in that aspect from a low of 0.100 to 1.900g. As to the influence of the size of the bore of dentifrice, the greatest amount of dentifrice was used ($0.670{\pm}0.306g$) when the bore of dentifrice was 9 mm in size, and the bore size 9 mm was significantly different from the size 3 mm and 6 mm in that aspect (p<0.001). 3. There was one kind of imported dentifrice for children on the market. Concerning the fluoride ingredient of dentifrice, the biggest number of dentifrice contained MFP only. As to the size of the bore of dentifrice, there was a difference of 3 to 9 mm. Most of dentifrice for children included the pictures of particular characters. Conclusions : The above-mentioned findings illustrated that there is a serious concern for the intake of fluoride among infants and preschoolers, it's needed to pay careful attention to the use of dentifrice. Dentifrice for children should be manufactured in consideration of the relationship between the size of the bore and the amount of dentifrice used.
