Disease was classified classification, compared published data EUROKIDS study.A total 255 included. The median 14.7 (range,...
Hepatocyte apoptosis and inflammation play important roles in cholestatic liver diseases. Bee venom-derived secretory phospholipase A2 (bvPLA2) has been shown to ameliorate various inflammatory However, whether bvPLA2 a therapeutic effect against disease not evaluated. Therefore, we investigated the effects of on injury fibrosis murine model 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet feeding. The administration ameliorated damage, cholestasis, DDC diet-fed mice, as assessed by...
The aim of the study was to identify factors related recurrence intussusception in pediatric patients.The medical charts patients diagnosed with and treated at Dongsan Medical Center, between March 2015 June 2017, were retrospectively reviewed. Univariate multivariate analyses performed.Among 137 patients, 23 (16.8%) had a recurrent 8 these (6%) more than 2 episodes recurrence. age diagnosis significantly different non-recurrence group (p=0.026), >1 year time associated greater rate...
We investigated fecal calprotectin (FC) levels in preterm infants with and without feeding intolerance (FI), compared the FC according to type of feeding.The medical records 67 premature were reviewed retrospectively. The fully enteral-fed classified into two groups; FI group (29 infants) control (31 infants). Seven necrotizing enterocolitis, sepsis, perinatal asphyxia excluded. If breast milk (BM) or formula (PF) could not be tolerated by FI, amino acid-based (AAF) was tried temporarily....
Background: This study aimed to investigate the awareness and application of ROME IV criteria for functional constipation (FC) in real-world practices assessed differences between pediatric gastroenterologists (PGs) general pediatricians.Methods: A total 239 (47.8%) out 500 nationwide pediatricians answered a questionnaire diagnosis management FC; 60 were PGs (75% Korea).Results: 16.6% aware exact criteria.Perianal examination digital rectal practiced less, with higher tendency among (P <...
The effects of probiotics in children vary based on diseases and probiotic strains. We aim to investigate the effectiveness Saccharomyces boulardii lactulose for treating childhood functional constipation.This open-label randomized controlled trial was conducted at 10 university hospitals Korea. Children who were diagnosed with constipation allocated 3 groups (lactulose monotherapy, combination therapy, S. monotherapy). primary outcome treatment success rate that accordingly defined as ≥...
Favourable clinical data were published on the efficacy of CT-P13, first biosimilar infliximab (IFX), in pediatric inflammatory bowel disease (IBD); however, few studies have compared effect endoscopic healing (EH) and drug retention rate between IFX originator CT-P13. Therefore, we aimed to compare EH Children with Crohn's (CD) ulcerative colitis (UC)/IBD-unclassified (IBD-U) at 22 medical centers enrolled, a retrospective review conducted 1-year last follow-up. Clinical remission,...
Few studies on gastric tube interposition for esophageal reconstruction in children have assessed the long-term outcomes and quality of life (QoL). The aim this study is to evaluate QoL after a by reviewing our experiences with reconstruction.Twenty-six patients were included who underwent from 1996 2011 at institution. We reviewed medical records conducted telephone surveys, prospectively performed esophagography, endoscopy, 24-hour pH monitoring, manometry. median follow-up period 12...
Pathologic aerophagia (PA) may lead to bowel perforation or volvulus in mentally retarded patients. The authors investigated the effects of clonazepam on management PA children with severe profound mental retardation (MR).This study was undertaken as a retrospective case analysis 21 patients MR who were followed for over 12 months and diagnosed having PA. Patients assigned two groups, that is, randomized open-labeled, treatment group reassurance group. following recorded analyzed; age,...
We investigated whether the severity of anxiety among children undergoing endoscopy could affect sedation. prospectively recruited patients under 18 years age who were scheduled to undergo esophagogastroduodenoscopy (EGD). Baseline was evaluated using Spence Children's Anxiety Scale (SCAS). Our analysis considered type and dose sedative drugs, degree sedation, complications associated with sedation according scale score. The mean total SCAS T-scores each subscale score significantly higher...
Glycogen storage disease (GSD) IV is a rare autosomal recessive inherited disorder caused by mutations in the gene coding for glycogen branching enzyme leading to progressive liver disease. GSD associated with GBE1, which encodes enzyme. We report case of homozygous GBE1 (c.791G>A (p.Gly264Glu), was successfully treated transplantation.
Sedative upper endoscopy is similar in pediatrics and adults, but it characteristically more likely to lead respiratory failure. Although recommended guidelines for pediatric procedural sedation are available within South Korea internationally, Korean endoscopists use different drugs, either alone or combination, practice. Efforts being made minimize the risk of while avoiding challenges. The purpose this study was collect analyze data on methods used by help physicians perform sedative...
