The purpose of this study was to identify the factors associated with skipping breakfast of Korean children by analyzing the 24-hour recall intake data from the 2001 National Health and Nutrition Survey. The sample of this study consisted of 1,600 children aged 7 to 18 years. About 17% of the children skipped breakfast, consuming no food or beverage at all. About 30% of children reporting breakfast skipping in a self-administered survey were shown to have eaten some foods as a result of analysis of the 24-hour recall data. Students having eaten breakfast consumed 21% of Estimated Energy Requirement at breakfast. The multivariate logistic regression analyses showed that age was associated with skipping breakfast both in elementary and middle/high school students; older students were more likely to skip breakfast. Elementary school students from low-income families were more likely to skip breakfast than those from upper-high income families. Intervention programs are needed to prevent children from skipping breakfast by targeting older students. For elementary school students, such programs should be first developed for those from lowincome families.

This study was conducted in order to investigate the association between picky eating behaviors of preschool children and growth outcomes. In this study, picky eating behaviors were defined as containing four constructs of 'eating a small amount (ES),' 'neophoic behavior (NB),' 'refusal of specific food groups (RF),' and 'preference for specific food-preparation methods (PP).' A 7-point scale was used for the multi-item questionnaire, which consisted of 21 items (three items for ES, two items for NB, nine items for RF, and seven items for PP), in order to evaluate picky eating behaviors of children. Subjects were recruited among visitors at a medical clinic in Seoul. A total of 150 self-administered survey responses from parents of preschool children were analyzed in order to investigate the association between picky eating behaviors of preschool children and growth outcomes. Height for age (HFA) and weight for height (WFH) z-scores were used for assessment of preschool children's growth. The prevalence of ES, NB, RF, and PP was 44%, 57%, 73%, and 53%, respectively. Children with ES had lower HFA (p < 0.05) and WFH (p < 0.0001) than those without ES, while children with NB, RF, or PP had HFA and WFH were similar to their counterparts. The mean HFA z-score of children with ES was less than 0 (p < 0.05) and the mean WFH z-scores of children with ES, NB, RF, or PP were less than 0 (p < 0.05). According to the study results, related growth outcome differed depending on constructs of picky eating behaviors. In particular, picky eating of ES showed a risk of faltering height growth in preschool children. Further comprehensive studies on the reason for ES and intervention approach is warranted.

Solid pseudopapillary tumors of the pancreas (SPTPs) are rare tumors with limited malignant potential; they are mainly diagnosed in young women. Complete surgical resection of the tumor is usually possible and patients have an excellent prognosis. However, local invasion and distant metastases have been reported in about 10-20% of patients with SPTPs; these patients require supplementary management for long-term survival. Here, we report a pediatric patient with inoperable SPTP unresponsive to neoadjuvant chemotherapy using cisplatin, ifosfamide, and etoposide which had spread to other organs. Subtotal resection of the primary tumor, radiofrequency ablation, radiotherapy, and adjuvant chemotherapy using gemcitabine were done to control this progressive SPTP.

Purpose: The objective of this study was to analyze the results of several noninvasive prenatal tests (NIPTs) from a single center and confirm their efficacy and reliability. In addition, we aimed to confirm the changes in the number of invasive tests performed after introducing NIPT. Materials and Methods: NIPT data from a large single center from March 2014 to November 2018 were analyzed. Karyotyping was confirmed based on chorionic villus sampling, amniocentesis, or postnatal cord/peripheral blood sampling. Data on maternal age, gestational age, fetal fraction, and ultrasonographic results were analyzed. As the secondary outcome, the number of amniocentesis cases before and after the introduction of NIPT was compared. Results: Overall, 1,591 single pregnancy cases that underwent NIPT were enrolled. The mean maternal age was 36.05 (22-45) years. The average gestational age and fetal fraction were 12+1 (9+3 to 27+1) weeks and 10.95% (3.6% to 31.3%), respectively. A total of 1,544 cases (97.0%) were reported to have negative NIPT results and 40 (2.5%) had positive NIPT results. The sensitivity and specificity of the overall abnormalities in NIPT were 96.29% and 99.36%, respectively. The positive predictive value (PPV) and negative predictive value were 72.22% and 99.93% respectively. The mean number of amniocentesis cases were 21.7 per month (21.7±3.9), which significantly decreased from 31.5 per month (31.5±4.8) before conducting NIPT as a screening test. Conclusion NIPT is currently a useful, powerful, and safe screening test. In particular, trisomy 21 is highly specific due to its high PPV. NIPT can reduce the potential risks of procedure-related miscarriages during invasive testing.

Uterine arteriovenous vascular malformation (UAVM) is a disease that causes excessive bleeding. The symptoms do not subside without proper treatment and this can lead to life-threatening situations. The correct diagnosis of UAVM can be complicated if the patient's uterus did not completely discharge everything during abortion (in broader terms, retaining remnants of the products of conception). In this case, Doppler ultrasonography and computed tomography angiography with 3-dimensional rendering were used to analyze the cause of bleeding and provide proper treatment of this patient. Then, uterine artery embolization, dilatation, and curettage were performed safely and successfully. The patient no longer had symptoms of vaginal spotting during the planned follow up care. UAVM is uncommon; however, if reproductive-age women show repeated abnormal vaginal bleeding after dilatation and curettage, a diagnosis of UAVM must be considered based on the medical history and examination.

Background and Objectives: Surgery for bilateral chronic otitis media (COM) is usually performed sequentially, not simultaneously. The main reason is to prevent iatrogenic bilateral conductive hearing loss during recovery period. However, with asymmetric hearing loss, the difference in patient inconvenience between sequential and simultaneous surgery may be the same. This study evaluates the efficacy of simultaneous COM surgery in patients with asymmetric hearing.Subjects Materials and Method From 2012 to 2018, 9 patients underwent simultaneous bilateral COM surgery. The period of patients’ hospital stay, the success rate of tympanoplasty, tolerability for operation, and hearing thresholds were analyzed statistically. Results: For the 8 same-day surgery patients, the mean hospital period was 4.4±0.7 days, which was much shorter than that of sequential surgery (8 days). Tympanoplasty was successful in all patients without complications. In the better side, the preoperative/postoperative mean air conduction thresholds (AC) were 62.97±12.89 dB/47.81±19.07 dB (p=0.017), the bone conduction thresholds (BC) were 46.72±10.31 dB/37.66±16.99 dB (p=0.161) and the air-bone gaps (ABG) were 16.25±8.81 dB/10.16±7.78 dB (p=0.176). In the worse side, the preoperative/ postoperative mean AC were 86.56±18.22 dB/72.18±29.43 dB (p=0.035), BC were 53.28± 11.10 dB/48.13±18.41 dB (p=0.173), and ABG were 33.28±11.22 dB/24.06±14.80 dB (p=0.500). In both ear, the postoperative AC and BC were better than or equivocal to those of the preoperative value, and the result was similar with each of the unilateral ear audiological results. Conclusion Despite the fact that there is no complete consensus to date, simultaneous bilateral COM surgery can be an option when patients have asymmetric hearing loss. Simultaneous bilateral COM surgery could save time, cost, and lead to similar results with sequential surgery, so it could be a considerable surgical option for patients with bilateral COM.

Purpose: The aim of this study was to evaluate the physiological and behavioral effects of auditory stimulation with their own parent’s voice on heart rate and sleep states of very-low-birth-weight infants (VLBWIs) in neonatal intensive care unit. Methods: The data of 28 VLBWIs at the Ewha Womans University Mokdong Hospital between October 2016 and May 2017 was analyzed. They were exposed to sounds similar to those of mothers’ heartbeat they had heard in the uterus and their own parent’s voice. Heart rate was assessed as the physiological responses and sleep state of infants as behavioral response. The sleep states were categorized into six states. The music intervention program was provided twice a week. Results: Twenty-eight babies with an average gestational age of 28 weeks (average birth weight of 1.09 kg) had undergone the sessions (average of 16 times) average of 16 times. During the initial period, there were no meaningful differences of the heart rates measured by the physiological functions before and after the sessions. However, as we move to the adaptive phase, the average heart rate was 156.96±12.22, and the pre-discharge was 149.11±12.01, which indicates meaningful differences (P<0.05). Infants’ behavioral function was statistically insignificant. Conclusion The music intervention techniques in the neonatal intensive care unit environment in Korea have provided positive influence to VLBWIs' physiological reactions. We were not able to come up with the relevant indicators during this phase of the study but we do plan to announce the future study results after indexing the observation results.

Objective: : The goal of this study was to analyze the clinical outcomes of endoscopic third ventriculostomy (ETV) and endoscopic septostomy when shunt malfunction occurs in a patient who has previously undergone placement of a ventriculoperitoneal shunt. Methods: : From 2001 to 2020 at Seoul National University Children's Hospital, patients who underwent ETV or endoscopic septostomy for shunt malfunction were retrospectively analyzed. Initial diagnosis (etiology of hydrocephalus), age at first shunt insertion, age at endoscopic procedure, magnetic resonance or computed tomography image, subsequent shunting data, and follow-up period were included. Results: : Thirty-six patients were included in this retrospective study. Twenty-nine patients, 18 males and 11 females, with shunt malfunction underwent ETV. At the time of shunting, the age ranged from 1 day to 15.4 years (mean, 2.4 years). The mean age at the time of ETV was 13.1 years (range, 0.7 to 29.6 years). Nineteen patients remained shunt revision free. The 5-year shunt revisionfree survival rate was 69% (95% confidence interval [CI], 0.54–0.88). Seven patients, three males and four females, with shunt malfunction underwent endoscopic septostomy. At the time of shunting, the age ranged from 0.2 to 12 years (mean, 3.9 years). The mean age at the time of endoscopic septostomy was 11.9 years (range, 0.5 to 29.5 years). Four patients remained free of shunt revision or addition. The 5-year shunt revision-free survival rate was 57% (95% CI, 0.3–1.0). There were no complications associated with the endoscopic procedures. Conclusion : The results of our study demonstrate that ETV or endoscopic septostomy can be effective and safe in patients with shunt malfunction.

PURPOSE: Given that the indicators related to chronic diseases are important to evaluating goals of the national health policy, the aim of this study was to develop dietary behavior items available in the Korea National Health and Nutrition Examination Survey. METHODS: The dietary behavior items were developed based on the literature reviews, need assessment of the field, expert focus-group interviews, and expert advisory meeting. Questions for each dietary behavior item were developed by reflecting on environmental, personal, and behavior factors of the ecological frame and then revised through expert focus-group interview and expert advisory meeting. The understanding and reliability of the developed questionnaire were assessed by cognitive interview and test-retest reliability. RESULTS: The developed items were sodium and salt intake, added and simple sugar intake, enough time to consume a meal for all ages, caffeine drinks and fresh/healthy food intake for children and adolescents, and limited dietary intake, fresh/healthy food intake for seniors. In most questions except some questions on sodium and salt intake, subjects understood over 70% and consistency of responses based on the kappa values was acceptable. CONCLUSION: Developed dietary behavior items are expected to be useful for evidence-based nutrition policy, interventions and research targeting dietary patterns through investigating and monitoring dietary behavior patterns.
