Nontyphoidal Salmonella is a type of well-known foodborne pathogen that causes gastroenteritis, bacteremia, and subsequent focal infection. Moreover, colonic ulcers, caused by nontyphoidal Salmonella infection, are considered uncommon in children. We report on the case of a 32-month-old healthy female with diffuse left-side colonic ulcers that presented with copious hematochezia, caused by a Salmonella enteritidis infection.

Small bowel obstruction due to congenital band is not only rare in children, but also difficult to diagnose, because common symptoms such as vomiting and abdominal pain are observed in patients. In order to prevent a fatal result, an anomalous congenital band should be considered in the discriminative diagnosis of intestinal obstruction in children who have no previous experience of operation or intraperitoneal inflammation. This report presents a 4-year-old boy who was admitted with abdominal pain and nonbilious vomiting for a day. The initial suspicion was for acute gastroenteritis. However, after further investigation and performance of surgery, the intestinal obstruction associated with a congenital band was confirmed. No recurrence was observed during the 8-month follow-up period. Thus early confirmation based on radiologic study is a crucial factor for the diagnosis of small bowel obstruction caused by a congenital band.

Collagenous gastritis (CG) is a rare disorder that is characterized by the presence of a thick subepithelial collagen band with multiple infiltrated inflammatory cells of the gastric mucosa. CG is divided into two major subsets: first, in children and young adults presenting with severe anemia and abdominal colic pain (pediatric-type CG); and second, in adult patients with chronic watery diarrhea associated with collagenous colitis (adult-type CG). We report two cases of pediatric-type CG, each presenting with refractory anemia and chronic diarrhea.

PURPOSE: Recently, public interest in obesity and earlier pubertal development has been increasing. The purpose of this study was to analyze the relationship between obesity and pubertal development in girls. METHODS: A total of 158 girls presenting with earlier pubertal development from July 2008 to June 2010 were included in the study. Their mean age was 8.27+/-1.3 years and the mean bone age advancement was 1.86+/-0.3 years. RESULTS: Based on weight-for-height percentiles, their obesity rate was 9.2% and overweight rate was 15.8%. However, for body mass index (BMI), the result was a bit different; with an obesity rate of 13.2% and overweight rate of 24.3%. About 40% of the girls had a family history of early maturation. Among them, 25.7% had a maternal history, 4.6% paternal and 7.2% both. However, 60% of them had no family history. We then classified these girls into families with one son and one daughter, and those with two daughters. In one-son/one-daughter families, 69.3% were the first children and 30.7% were second. In two-daughter families, 65.3% were the first and 34.7% were second. We found that 67.5% had a history of taking herbal medicine. CONCLUSION: The obesity and overweight rates in girls with earlier pubertal development were higher than those of normal girls, but with a small discrepancy between weight-for-height percentile and BMI-based results. Furthermore, taking herbal medicine seems to be a potential factor for earlier pubertal development in Korea.

PURPOSE: The aim of this study was to compare serum leptin, neuropeptide Y (NPY), and islet amyloid polypeptide (amylin) levels in obese and normal weight children, and to investigate their correlations with anthropometric parameters and metabolic bio-marker levels. METHODS: Body mass index (BMI), waist and hip circumference, blood pressure (systolic/diastolic), lipid profile, fasting glucose, and serum insulin, leptin, NPY, and amylin levels were measured in 56 children (24 obese children and 32 non-obese controls). Homeostatic model assessment-insulin resistance (HOMA-IR) values were calculated and the relationships between anthropometric variables, metabolic biomarkers, and diet-regulating factors (leptin, NPY, and amylin levels) were examined. RESULTS: BMI, hip circumference, waist circumference, and systolic and diastolic pressure were significantly higher in the obese group than in the non-obese group (p<0.0001). Total cholesterol, triglyceride, low-density lipoprotein-cholesterol, glucose, and insulin levels were also significantly higher in the obese group (p<0.05). On the other hand, high-density lipoprotein-cholesterol levels were higher in the non-obese group , but this was not significant. Serum leptin, NPY, and amylin levels were significantly higher in the obese group (p<0.05). Furthermore, in the obese group, leptin levels were found to be significantly correlated with BMI (r=0.379, p=0.043), and NPY levels (r=0.377, p=0.044), and amylin levels were found to be significantly correlated with insulin levels (r=0.400, p=0.048), and HOMA-IR (r=0.459, p=0.028). CONCLUSION: Metabolic risk factor alterations are present in obese children, and these children show abnormalities in the diet regulatory system caused by leptin, NPY, and amylin resistance. Of particular note, amylin was found to be positively correlated with insulin resistance.

PURPOSE: To compare the abilities of radionuclide salivagrams (RS) and videofluoroscopic swallow studies (VFSS) to diagnose aspiration in children with aspiration pneumonia. METHODS: The records of children who were referred to the Asan Medical Center between April, 2006 and April, 2012 and who underwent both VFSS and RS to evaluate their recurrent aspiration pneumonia were reviewed (n=67). The aspiration positivity rates of the two tests were determined. The agreement between the tests was assessed by using the kappa statistic. RESULTS: VFSS was more frequently positive (n=26, 39%) than RS (n=23, 34%) (p=0.68). In the 11 children who repeat two test, Repeated examination increased positive rate in each tests (n=11), repeated RS (54%, p=1) is more frequent positive than repeated VFSS (46%, p=0.37). If a cumulative positive test had been defined as at least one positive result, the positive rate of two test was 56% (p<0.05). There was a fair agreement between RS and VFSS (kappa=0.26). CONCLUSION: The RS and VFSS positivity rates in children with aspiration pneumonia were similar but there was fair agreement between the two tests. This result suggests that these investigations to demonstrate aspiration are not interchangeable but complementary.

During the past decades, advancement in pubertal maturation in children has been noticed worldwide. Growing evidence indicates that increasing prevalence of obesity in children is a major factor for the secular trend of earlier puberty. In girls, several epidemiologic studies suggest that earlier pubertal onset and earlier menarche might be caused by obesity. On the other hand, in boys, few research reported an association between obesity and pubertal development, and the results are inconsistent; Some studies found a link between obesity and delayed puberty, but others reported a causal relationship between obesity and early puberty. To date, mechanisms linking childhood obesity and earlier puberty remain unclear. In this review, we presented the potential impact of obesity on puberty-related hormones and summarized human studies on potential relationship of childhood adiposity and pubertal development.

Nutrients are defined as not only having nutritive values of participating in the metabolism and building the structures of cells but also being safe for human body. Nutrients are divided into two types, macronutrient and micronutrient, according to the proportion of the human body. Commonly, micronutrients include trace elements (trace mineral) and vitamins (complex organic molecules). It is difficult to demonstrate micronutrient deficiency because the symptoms are varied and laboratory analyses are limited. Since parenteral nutrition became an established therapy, micronutrient deficiency syndromes are being identified more frequently and emphasize the importance of a complete nutritional support. In this article, we review various specific trace element deficiency states such as zinc, copper, and selenium and briefly discuss the use of dietary supplements.

The clinical importance of vitamin D has been recently highlighted, due to non-skeletal effects of vitamin D and the fact that vitamin D receptors are observed in many kinds of cells. Vitamin D deficiency or insufficiency results in the development of gastrointestinal diseases, including obesity, hepatitis B, chronic hepatitis C, and inflammatory bowel disease in children. The prevalence of vitamin D insufficiency in 188 Korean adolescents, aged 12-13 years, was 98.9% for boys and 100% for girls. This article reviews recent publications, regarding vitamin D deficiency and childhood gastrointestinal diseases, and introduces new treatment and prevention guidelines for vitamin D deficiency.

Pediatric intestinal failure occurs secondary to short bowel syndrome, motility disorders, or malabsorption. The establishment of an intestinal rehabilitation program and the introduction of innovative surgical and medical treatments, such as the serial transverse enteroplasty procedure and omega-3-containing lipid emulsions, have been major advances in the treatment of intestinal failure. Intestinal transplantation is now established as a therapeutic modality in selected children with irreversible intestinal failure. The improved short to intermediate term survival of intestinal transplant recipients in the last decade can be attributed to immunosuppression with a lymphocyte-depleting agent, control of acute cellular rejection, and comprehensive infection control with careful monitoring of viral pathogens including cytomegalovirus and Epstein-Barr virus.
