Although Helicobacter pylori infection rate in children is unclear due to diversity and limitation of diagnostic tests unlike in adults, investigation the childhood prevalence is important for predicting H. pylori-related diseases in the future. H. pylori infection occurred in early childhood, and declined during 30 years in our study. Change in risk factors of H. pylori transmission and consensus for eradication therapy in children might further reduce the infection rate. |

Question: What is the normal renal size of Thai children and is the renal nomogram comparable to those of Western and Chinese cohorts? Finding: The renal length of Thai children was moderately correlated with that of Western children, while the age-specific renal volume was significantly smaller than that of Chinese children. Meaning: Renal size in children can vary among regions and sociodemographic backgrounds; hence, a local reference standard is needed. |
Question: How to manage the newborn born to the coronavirus disease 2019 (COVID-19) pregnant? Finding: Medical staff managed the delivery and neonatal care of a COVID-19 pregnant patient was based on the “Guidelines for COVID-19 response.” Meaning: We desire that our management will help treat for subsequent patients and there should be updated continuously the prevention and control consensus strategies for newborn COVID-19. |

Although the precise pathogenesis of inflammatory bowel disease (IBD) is unclear, dietary factors seem to play a significant role. Dietary modifications including enteral nutrition and the Crohn disease exclusion, specific carbohydrate, and anti-inflammatory diets show a potential ability to downregulate gut inflammation. These nutritional interventions have various degree of efficacies with limited side effects profile for treating pediatric IBD, but data from randomized prospective studies are lacking, and further studies are warranted. |
A new coronavirus disease 2019 (COVID-19) has been spreading globally since December 2019. Children with a Kawasaki disease (KD)-like illness related with COVID-19 have been reported in Europe and the United States. They presented with symptoms of KD with or without cardiac abnormalities or shock, showing manifestations of hyperactive proinflammatory cytokine reactions like KD. Such cases may provide the opportunity for us to learn more about the etiology and pathogenesis of KD. |

Macrolides are the first line treatment in atypical pneumonia caused by M. pneumoniae, C. pneumoniae, and L. pneumophila. Macrolide-resistant mycoplasma pneumonia (MRMP) is emerging worldwide, especially in East Asia. Immune modulators such as corticosteroids or second line antibiotics are treatment options for MRMP. Pediatricians should be careful with empirical therapy of macrolides in children with mild to moderate community-acquired pneumonia not to increase the risk of MRMP. |

Question: Hospitalization in neonatal intensive care unit (NICU) is associated with life-threatening hazards. What factors associated with neonatal length of stay (LOS) in the NICU? Finding: Breastfeeding, phototherapy, acute renal failure (ARF), mechanical ventilation, and central venous catheter (CVC) access were identified as factors associated with NICU length of stay. Meaning: Protective effects of breastfeeding and CVC access, whereas increase effects of phototherapy, ARF, and mechanical ventilation in LOS can be supporting evidence to establish effective interventions to reduce length of NICU stay. |
