1.Therapeutic Iron and Zinc Supplementation in Children.
Pediatric Gastroenterology, Hepatology & Nutrition 2012;15(Suppl 1):S7-S16
Iron and zinc are essential nutrients for growth and development in children. Iron deficient anemia is the most widespread and common nutritional disorder. A deficiency of iron results in fatigue, poor work performance, decreased immunity and possible irreversible effects on the early cognitive development. Oral administration of ferrous salts (most often ferrous sulfate) provides inexpensive and effective therapy. On the other hand, because of low nutritional requirements and plentiful supply, deficiencies of zinc are rare. Children may have apparently asymptomatic deficiencies of zinc, but still benefit from supplementation. Zinc is a crucial micronutrient because it affects various immune mechanisms and modulates host resistance to several pathogens. Zinc supplementation of at-risk children reduces the incidence and severity of diarrhea, pneumonia, and possibly common cold. Early identification of risk factors and nutritional intervention with sufficient iron and zinc supply is much more important than therapeutic supplementation.

Our objective was to determine the risk factors associated with the development of functional constipation (FC) in young children attending daycare centers. A cross-sectional survey using a questionnaire based on the Rome III criteria was conducted in children aged 25 to 84 months from 3 randomly selected daycare centers in January 2016. The items in a questionnaire were statistically compared in the constipated and non-constipated groups. A total of 212 children were included and FC was found in 8.5%. Multivariate logistic regression analyses revealed that maternal history of constipation (odds ratio [OR] = 4.1, 95% Confidence Interval [CI] 1.2-13.9), history of painful defecation before age 1 (OR = 10.4, 95% CI 1.1-101.3), history of painful defecation during toilet training (OR = 28.9, 95% CI 1.9-423.8), no or difficult defecation at a daycare center (OR = 5,804.6, 95% CI 134.4-250,718.4), no meat consumption (OR = 10.1, 95% CI 1.2-88.1), and 500 mL or less of water intake per day (OR = 9.9, 95% CI 0.9-99.5) were powerful predictors of FC in young children (P < 0.05). Additionally, the constipated group was significantly associated with 2 hours or less of outdoor play activities per day, entry into daycare centers before 24 months age, 6 hours or more of attendance at a daycare center per day, breastfeeding for less than 6 months, 3 meals or less per day, and 3 or fewer servings of fruits and vegetables per day (P < 0.05). The findings of this study can guide parents, daycare teachers, and clinicians in prevention, early recognition and early intervention for the risk factors associated with FC in young children.

4.Hepatitis A.
Korean Journal of Pediatric Gastroenterology and Nutrition 2010;13(Suppl 1):S70-S77
Hepatitis A characteristically is an acute, self-limited illness associated with fever, malaise, jaundice, anorexia, and nausea. The development in the socio-economic status and public health of Korea over the last 30 years have been accompanied by a shift in age-specific rates of hepatitis A. This lowered endemicity has caused an upward shift in the average age of infection, resulting in a larger number of individuals at risk of clinically significant hepatitis A infection. Vaccination is the most effective means of preventing hepatitis A virus transmission among persons at risk for infection.

Korean Journal of Pediatrics 2016;59(3):126-131
PURPOSE: To evaluate the diagnostic value of the Vesikari Scoring System (VSS) as an early predictor of pathogens in children with acute gastroenteritis (AG). METHODS: In this retrospective study, the VSS score, absolute neutrophil count (ANC), and C-reactive protein (CRP) levels were analyzed in 107 hospitalized children with AG, aged 6 months to 17 years. Patients were divided into nonspecific, viral, and bacterial groups according to the pathogens detected using a multiplex polymerase chain reaction (PCR) test. RESULTS: Patients in the bacterial group had significantly higher CRP values and VSS scores compared to those in the viral group and significantly higher VSS scores compared to those in the nonspecific group (P<0.05). Patients in the viral group had significantly higher VSS scores than those in the nonspecific group (P<0.05). Logistic regression analysis revealed that VSS was the most effective diagnostic tool for predicting the type of pathogen (P<0.05). The area under the receiver operating characteristics curve of VSS was significantly greater than that for ANC and CRP (P<0.05). At a cutoff point of 10 in the VSS, an acceptable diagnostic accuracy could be achieved for distinguishing between bacterial and viral pathogens in AG. CONCLUSION: VSS can be considered a useful and reliable infectious marker for pediatric gastroenteritis. VSS may be a good early predictor of the type of pathogen, enabling development of a treatment plan before results from a stool culture or PCR test are available.

Korean Journal of Pediatric Gastroenterology and Nutrition 2008;11(2):150-159
PURPOSE: To assess the relationship between lifestyle and metabolic syndrome in obese children and adolescents. METHODS: We retrospectively reviewed the medical records and laboratory results of 109 subjects (7~15 years of age) who visited our pediatric obesity clinic between January 2004 and December 2007. They completed the parent- and self-report questionnaire developed by the Committee on Nutrition of the Korean Pediatric Society to assess lifestyle. The metabolic syndrome was defined as having 3 or more of the following metabolic risk factors: obesity, hypertension, serum triglycerides > or =110 mg/dL, HDL-cholesterol < or =40 mg/dL, fasting glucose > or =110 mg/dL, and insulin > or =20 micronIU/mL. RESULTS: All subjects had at least 1 risk factor (obesity). Sixty-three percent of subjects had 2 or more risk factors, 32% of subjects had 3 or more risk factors, and 10% had 4 or more metabolic risk factors. Hypertriglyceridemia (36%), hypertension (32%), hyperinsulinemia (24%), and HDL-hypocholesterolemia (20%) were observed. Fasting blood glucose levels were normal in all subjects. Hypertension was significantly associated with an unbalanced diet and hyperinsulinemia was significantly associated with parental obesity (p<0.05). Those who ate after 8 PM were at a risk of hypertension (odds ratio, 2.5; 95% CI, 1.0~6.1). Those who did not have a preference for exercise were at a risk of hyperinsulinemia (odds ratio, 10.4; 95% CI, 2~54.1). Those who watched TV for > or =3 hours/day were at a risk of metabolic syndrome (odds ratio, 4.8; 95% CI, 1.2~18.8). CONCLUSION: Lifestyle, such as eating late, no preference for exercise, and TV watching > or =3 hours/day, were related to metabolic syndrome in obese children and adolescents.

Allergy, Asthma & Respiratory Disease 2020;8(4):237-240
Eosinophilic gastroenteritis (EGE) is known to have a low incidence among the pediatric population, but it can result in serious complications, such as gastric outlet obstruction. In previously published EGE cases with the obstruction in adults, surgeries were often performed. In this report, we present a 14-year-old girl who came to our facility with severe abdominal pain and vomiting. On the initial abdominal physical examination, diffuse tenderness and severe epigastric pain were noted. Computed tomography scan of the abdomen showed the findings of superior mesenteric artery (SMA) syndrome. However, she had no history of recent weight loss, and the medical history was inconsistent with SMA syndrome. We planned upper gastrointestinal series with barium, and then verified gastric outlet obstruction. We performed esophagogastroduodenoscopy and obtained a final diagnosis of EGE through mucosal biopsy specimen. Corticosteroids and anti-inflammatory medications were administered. Dietary modification and education were done as well. The symptoms resolved, and the follow-up esophagogastroduodenoscopy and ultrasonography showed improvements in the obstruction. Our case emphasizes that gastric outlet obstruction due to EGE must be carefully differentiated from SMA syndrome because of their similarities in clinical features and radiologic images. In doing so, we can avoid surgical intervention and perform medical/dietary treatment for gastric outlet obstruction.

A group of patients with Kawasaki disease (KD) initially present with cervical lymphadenitis or deep neck infection. These unusual KD presentations lead to unnecessary antibiotic therapy or surgical intervention, thereby delaying intravenous immunoglobulin treatment and increasing the risk of coronary artery damage. We present four KD patients whose initial presentations mimicked a retropharyngeal abscess. Nonsuppurative cervical lymphadenitis or suspected neck abscess unresponsive to intravenous antibiotics could signal the possibility of KD.

Pediatric Gastroenterology, Hepatology & Nutrition 2021;24(3):279-287
Purpose:
The clinical implications of bowel wall thickening (BWT) on abdominal computed tomography (CT) among children are unknown. We aimed to suggest a new method for measuring BWT and determining its clinical significance in children.
Methods:
We retrospectively analyzed 423 patients with acute abdomen who underwent abdominal CT; 262 were classified into the BWT group. For this group, the pediatric radiologist described the maximal bowel wall thickness (MT), normal bowel wall thickness (mm) (NT), and their ratios for each segment of the bowel wall.
Results:
In the thickened bowel walls, the thickness differed significantly between the small bowel (6.83±2.14 mm; mean±standard deviation) and the colon (8.56±3.46 mm; p<0.001). The ratios of MT to NT in the small bowel (6.09±3.17) and the colon (7.58±3.70) were also significantly different (p<0.001). In the BWT group, 35 of 53 patients had positive fecal polymerase chain reaction results; 6 patients infected with viruses predominantly had BWT in the small intestine, while the terminal ileum and the colon were predominantly affected in 29 patients with bacterial infections. In the initially undiagnosed 158 patients with BWT, the symptoms improved spontaneously without progression to chronic gastrointestinal disease.
Conclusion
This study provides a clinical reference value for BWT in the small intestine and colon using a new method in children. The BWT on abdominal CT in children might indicate nonspecific findings that can be observed and followed up without additional evaluation, unlike in adults.
