APRI may be used as a simple and readily available tool for assessing liver fibrosis without additional risks in patients with BA during postoperative follow-up care.

The present study is the largest to show the high incidence and characteristics of cholangitis after KPE in patients with biliary atresia. Enterococcus is a common pathogen of cholangitis after KPE and should be considered when choosing empiric antimicrobial therapy.

The Leech score and the Bristol stool form scale may be simple and useful diagnostic tools for pediatricians to access childhood fecal loading in outpatient clinics along with a thorough clinical history.

Currently, there are a few reports on viral coinfection that causes an acute watery diarrhea in Korean children. So, to evaluate the features of coinfectious viral agents in children with acute watery diarrhea, we enrolled 155 children with acute watery diarrhea from July 2005 to June 2006. Fecal samples were collected and evaluated for various viral infections such as rotavirus, norovirus, adenovirus and astrovirus. The mean (+/-standard deviation) age of the children was 2.71+/-2.37 yr. The de

The prevalence of metabolic syndrome is increasing worldwide in adolescents. Metabolic syndrome is a systemic disease that is likely to be associated with other diseases. Studies have shown a relationship between muscle strength, muscle quality, and metabolic syndrome. Handgrip strength is known as a simple tool to measure muscle strength. Therefore, we aimed to investigate the relationship between handgrip strength and metabolic syndrome and each metabolic syndrome features in adolescents. Data

Logistic regression revealed a significant increase in the incidence of nodular gastritis with gastritis score (p=0.008), but not an association with sex, age, or H. pylori density. Gastritis score was the only significant factor influencing the occurrence of nodular gastritis. Intestinal metaplasia, which was originally thought to be a pre-malignant lesion, occurred in 2.7% of the patients with H. pylori infection.

The LSM value of 3 months after Kasai HPE can be a useful predictor of LRE development.

Biliary atresia (BA) results in severe bile blockage and is caused by the absence of extrahepatic ducts. Even after successful hepatic portoenterostomy, a considerable number of patients are likely to show progressive deterioration in liver function. Recent studies show that mutations in protein-coding mitochondrial DNA (mtDNA) genes and/or mitochondrial genes in nuclear DNA (nDNA) are associated with hepatocellular dysfunction. This observation led us to investigate whether hepatic dysfunctions

Chronic liver disease including non-alcoholic fatty liver disease and alcohol-related liver disease is one of the most common diseases worldwide. The gut-liver axis plays an important role in the pathogenesis of liver disease. Small intestinal bacterial overgrowth, dysbiosis, leaky bowel, bacterial translocation, and imbalanced metabolites are related to the progression of chronic liver disease. Recently, novel therapeutic approaches for microbiota modulation such as personalized diet, probiotic

We recommend that the S1 probe is more appropriate for use in small children, especially those with a thorax perimeter of < 45 cm. If no S probe is available, the M probe may be acceptable in children whose thorax perimeter is > 45 cm.

Nonalcoholic steatohepatitis (NASH) is associated with imbalance of gut microbiome, indicating participation of gut environment in hepatic health status. Therefore, modulating gut environment via fecal microbiota transplantation (FMT) is a promising therapeutic procedure for NASH patients. However, the effect and mechanism of the FMT remains largely unknown. Here, we investigated the gut-liver axis to understand the FMT-mediated hepatic improvement in NASH. Feces from specific pathogen free mice

Lamivudine therapy had a significant effect on HBeAg seroconversion and HBV-DNA disappearance, and ALT normalization for Korean children with chronic hepatitis B.

Hereditary spherocytosis (HS), a common form of inherited hemolytic anemia, is a heterogeneous group of disorders with regard to clinical severity, protein defects, and mode of inheritance. Causal mutations in at least five genes have been reported so far. Because multiple genes have been associated with HS, clinical genetic testing that relies on direct sequencing will be a challenge. In this study, we used whole exome sequencing to identify a novel nonsense mutation in ANK1 (p.Q1772X, NM_02047

Hepatic fat quantification MR can be a non-invasive, quantitative and useful tool for monitoring treatment effects in pediatric NASH.
