Yu Kyung Cho, Jin Lee, Chang Nyol Paik
Clin Exp Pediatr. 2023;66(9):377-383.   Published online August 21, 2023
· Pediatric small intestinal bacterial overgrowth (SIBO) manifestations range from nonspecific abdominal symptoms to malabsorption or malnutrition.
· SIBO is prevalent in children and adolescents with functional abdominal pain disorders.
· Predisposing factors include disturbed intestinal motility, altered anatomy, and/or abnormal body defense systems against intestinal bacteria.
· Breath tests are safe and noninvasive.
· Treatment principles include managing predisposing conditions, nutritional support, symptom control, and antibiotics.

Clin Exp Pediatr. 2013;56(10):424-430.   Published online October 31, 2013

Exhaled nitric oxide (NO) has been extensively investigated as a noninvasive marker of airway inflammation in asthma. The increased NO expression induced by inflammatory mediators in airways can be monitored easily in exhaled air from asthmatic children. Based on the relationship between the increased NO expression and eosinophilic airway inflammation, fractional exhaled nitric oxide (FeNO) measurements become an important adjunct...

Helicobacter pylori reinfection rate by a 13C-urea breath test and endoscopic biopsy tests in Korean children
Jeong Ok Shim, Jeong Kee Seo
Clin Exp Pediatr. 2006;49(3):268-272.   Published online March 15, 2006
Purpose : The reinfection rate of H. pylori reported before 13C-urea breath test(13C-UBT) era was higher than that of the post 13C-UBT era. Children are usually reluctant to receive invasive endoscopic evaluation for the reinfection of H. pylori, particularly when they are asymptomatic. The aim of the study is to discover the reinfection rate by different diagnostic tests, and to...
