Breastfeeding and it's tolerance are the positive indicators for preterm babies. Placing the preterm infant in the right lateral or prone position after feed had lesser gastric residual volume compared to placing them in left lateral or supine positions. The post-feed position is a vital element in enhancing feeding tolerance, mechanical functions of the gastrointestinal tract and the overall development of preterm infants.

Allergy

Recent topics on gastrointestinal allergic disorders

Yoshiyuki Yamada

Clin Exp Pediatr. 2023;66(6):240-249. Published online January 9, 2023

Gastrointestinal (GI) allergies are divided into immunoglobulin E (IgE)-mediated, non-IgE-mediated, and mixed types. In addition to non-IgE-mediated, overlapping eosinophilic GI disorders (EGIDs) have increased in Japan. EGIDs, a mixed-type allergy category, include eosinophilic esophagitis (EoE) and non-EoE EGIDs. The number of EoE cases has increased in Western countries, followed by Asian countries. Recent GI allergies may also be associated with type 2 inflammation.

Update on eosinophilic gastrointestinal disease beyond eosinophilic esophagitis in children

Hye Ran Yang

Clin Exp Pediatr. 2023;66(6):233-239. Published online January 3, 2023

· Eosinophilic gastrointestinal disease (EGID) is uncommon, with a prevalence of 1–30/100,000 in the general population; however, it is increasing worldwide.
· The diagnosis of EGID is based on histopathological findings of endoscopic mucosal biopsy in which tissue eosinophils are counted in each gastrointestinal tract segment of patients with chronic or recurrent gastrointestinal symptoms.
· Individualized treatment strategies, including adequate dietary and pharmacological therapy, may help improve outcomes of children with EGID.

COVID-19 in immunocompromised children and adolescents

Byung Ok Kwak, Byung Wook Eun

Clin Exp Pediatr. 2023;66(5):182-189. Published online April 18, 2023

Most immunocompromised children and adolescents are not at increased risk of developing severe coronavirus disease 2019 (COVID-19). COVID-19 outcomes for low- or medium-risk immunocompromised children are favorable, while more serious illness reportedly occurs in high-risk immunocompromised children by underlying disease, its treatments, and other factors. Therefore, the early detection and timely management of severe COVID-19 and treatment of underlying disease are important. Hospitalization and COVID-19 vaccination should be carefully considered.

Question: What is the spatial distribution and determinants of coronavirus disease 2019 (COVID-19) infection among students in Korea?
Finding: The community population was closely associated with the risk of COVID-19, and the number of students per school class were inversely associated with COVID-19 rates in students.
Meaning: Our finding suggests that controlling the community-level burden of COVID-19 can help prevent sudden acute respiratory syndrome coronavirus 2 infection in school-aged children.
