Changes in Etiology of Invasive Bacterial Infections in Infants Under 3 Months of Age in Korea, 2006-2020.

Objectives: Invasive bacterial infection (IBI) causes a significant burden in infants. In this study, we analyzed changes in epidemiology of IBI among infants in Korea.

Methods: A retrospective multicenter-based surveillance for IBIs in infants <3 months of age was performed during 2006-2020.

Plasma midkine concentrations in healthy children, children with increased and decreased adiposity, and children with short stature.

Background: Midkine (MDK), one of the heparin-binding growth factors, is highly expressed in multiple organs during embryogenesis. Plasma concentrations have been reported to be elevated in patients with a variety of malignancies, in adults with obesity, and in children with short stature, diabetes, and obesity. However, the concentrations in healthy children and their relationships to age, nutrition, and linear growth have not been well studied.

[Disturbed maturation of oligodendrocyte progenitors in lipopolysaccharide-induced hypomyelination in cultured forebrain slices of neonatal rats].

Introduction: This study was performed to determine whether the disturbed maturation of oligodendrocyte (OL) progenitors might be related to lipopolysaccharide (LPS)-induced hypomyelination.

Material And Methods: We created organotypic cultures of forebrain slices from neonatal rats and explored the morphological changes of glial cells expressing tumour necrosis factor  (TNF-) following LPS exposure.

Results: We observed marked activation of glial fibrillary acidic protein-positive astrocytes and OX42-positive microglia co-labelled with TNF- four days following LPS exposure.

Etiology of Invasive Bacterial Infections in Immunocompetent Children in Korea (2006-2010): a Retrospective Multicenter Study.

Background: Invasive bacterial infections in apparently immunocompetent children were retrospectively analyzed to figure causative bacterial organisms in Korea.

Methods: A total of 947 cases from 25 university hospitals were identified from 2006 to 2010 as a continuance of a previous 10-year period study from 1996 to 2005.

Results: Escherichia coli (41.

[Peutz-Jeghers Syndrome with Adenomatous Change in a Fifteen-month-old Boy].

Peutz-Jeghers syndrome (PJS) is a very rare genetic disorder. PJS carries a high risk of developing gastrointestinal (GI) cancer or non-GI cancer with advancing years. However, major symptoms of PJS in childhood are obstruction, intussusception, and bleeding from hamartomatous intestinal polyps which in majority of cases are not related to cancer.

The status of dietary supplements intake in korean preschool children: data from the Korea national health and nutrition examination survey 2010-2012.

Purpose: The use of dietary supplements (DS) has increased in most nations. We investigated the amount of DS intake in the Korean population by analyzing a national survey, to support the preparation of a national institutional strategy regarding DS intake and marketing.

Methods: The data of the fifth Korea National Health and Nutrition Examination Survey (a year between 2010 and 2012) were investigated, analyzing the rate of DS intake, and the characteristics of the intake group and non-intake group in Korean preschool children.

Respiratory effects of the hebei spirit oil spill on children in taean, Korea.

Purpose: The oil spill from the Heibei Spirit in December 2007 contaminated the Yellow Coast of South Korea. We evaluated the respiratory effects of that spill on children who lived along the Yellow Coast.

Methods: Of 662 children living in the area exposed to the oil spill, 436 (65.

How to do in persistent diarrhea of children?: concepts and treatments of chronic diarrhea.

Chronic diarrhea is defined as passing watery stools that lasts for more than 2 weeks. Persistent diarrhea belongs to chronic diarrhea and is a chronic episode of diarrhea of infectious etiology. The etiology of chronic diarrhea is varied.

[The seroprevalence rate, vaccination rate and seroconversion rate of hepatitis A in central region of Korea].

Background/aims: Acute hepatitis A (HAV) is markedly increasing recently on. Some patients with acute hepatitis A show severe clinical course. The seroprevalence rate of IgG anti-HAV has been changing with the regions and the times.

Novel influenza A (H1N1) virus infection in children: chest radiographic and CT evaluation.

Objective: The purpose of this study was to evaluate the chest radiographic and CT findings of novel influenza A (H1N1) virus infection in children, the population that is more vulnerable to respiratory infection than adults.

Materials And Methods: The study population comprised 410 children who were diagnosed with an H1N1 infection from August 24, 2009 to November 11, 2009 and underwent chest radiography at Dankook University Hospital in Korea. Six of these patients also underwent chest CT.

Congenital intrahepatic portosystemic venous shunt and liver mass in a child patient: successful endovascular treatment with an amplatzer vascular plug (AVP).

A congenital intrahepatic portosystemic shunt is a rare anomaly; but, the number of diagnosed cases has increased with advanced imaging tools. Symptomatic portosystemic shunts, especially those that include hyperammonemia, should be treated; and various endovascular treatment methods other than surgery have been reported. Hepatic masses with either an intra- or extrahepatic shunt also have been reported, and the mass is another reason for treatment.

Rare association of tracheal diverticulum with pulmonary artery sling and aberrant right subclavian artery.

Tracheal diverticulum is a rarely encountered entity characterized by single or multiple invaginations of the tracheal wall. Two types of tracheal diverticula exist: congenital and acquired. We report a case of a pulmonary artery sling with an aberrant right subclavian artery associated with tracheal diverticulum.
