Treatment targeting pediatric inflammatory bowel disease-associated anemia: experience from a single tertiary center
Ana SC Fernandes, Sara Azevedo, Ana Rita Martins, Ana Isabel Lopes
Background: Iron deficiency (ID) and iron deficiency anemia (IDA) are common complications of pediatric inflammatory bowel disease (IBD). Owing to questions regarding optimal iron formulation, dosage, route of administration, and safety, these complications are frequently overlooked and undertreated, negatively impacting patient development and quality of life.
Purpose: To assess the safety and efficacy of iron sucrose (IS) and ferric carboxymaltose (FCM)...

Effect of postoperative enteral protein supplementation on nitrogen balance in critically ill children
Irene Yuniar, Kadek Apik Lestari, Antonius Hocky Pudjiadi, Fatima Safira Alatas, Yoga Devaera
Background: Critically ill children are at risk of postoperative malnutrition. Thus, optimal nutritional therapy is essential for preventing morbidity development and reducing mortality rates among this population. An adequate protein intake increases anabolism. However, data on the effect of enteral protein supplementation on nitrogen balance and intestinal fatty acid–binding protein (I-FABP) levels in postoperative critically ill children remain limited.
Purpose: This...

Global burden of asthma among children and adolescents with projections to 2050: a comprehensive review and forecasted modeling study
Tae Hyeon Kim, Hyunjee Kim, Jiyeon Oh, Soeun Kim, Michael Miligkos, Dong Keon Yon, Nikolaos G Papadopoulos
Clin Exp Pediatr. 2025;68(5):329-343.   Published online April 22, 2025
Pediatric asthma can persist to adulthood and must be effectively managed. This review examined the prevalence of asthma among individuals younger than 20 years and revealed a decline from 1990 to 2021, higher rates in males, and a peak in children aged 5–9 years. Despite a projected continued decrease in prevalence by 2050, asthma will remain a significant health concern for children and adolescents.

Yeon Woong Chung
Myopia, among the most common vision disorders worldwide, is projected to affect approximately 50% of the world's population by 2050. Its prevalence is particularly high in East Asia, posing a considerable public health challenge. In particular, high myopia, defined as ≤6.0 diopters, significantly increases an individual's lifetime risk of vision-threatening complications. Moreover, recent studies revealed that non-ophthalmological factors such as...

NLRP3 inflammasome: A key player in neonatal brain injury
Cagla Kiser, Ilkcan Ercan, Defne Engur, Sermin Genc
Among neonates, hypoxic-ischemic encephalopathy is the most significant cause of mortality and hypoxia-ischemia is among the leading causes of brain damage. The microglia are primary mediators of neuroinflammation. NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome activation is the first line of defense in the central nervous system. Numerous studies have shown that the NLRP3 inflammasome is activated and...

Impact of hematopoietic stem cell transplantation on growth outcomes in mucopolysaccharidosis: a systematic review
Farzaneh Abbasi, Asal Khalili Dehkordi, Reihaneh Mohsenipour
Clin Exp Pediatr. 2025;68(6):417-427.   Published online March 11, 2025
Hematopoietic stem cell transplantation (HSCT) enhances the growth outcomes of pediatric patients with mucopolysaccharidosis, with early intervention leading to improved height, weight, and body mass index. However, achieving a standard adult height remains uncommon among these patients, even in cases of early HSCT. Growth hormone therapy provides short-term benefits but does not address long-term height deficits. Pubertal development is generally normal; however, precocious puberty and pubertal arrest may occur.

Upasana Ghosh, Ankit Agrawal, Umesh Shukla, Vikas Jain, Deeksha Bhalla
Clin Exp Pediatr. 2025;68(5):395-397.   Published online March 11, 2025
· Chronic abdominal pain caused by a gastric trichobezoar is extremely rare among children.
· An indentable epigastric mass is characteristic and upper gastrointestinal endoscopy is diagnostic of a gastric trichobezoar.
· Symptomatic large trichobezoars usually require surgery.
· Neuropsychiatric disorders are often associated with gastric trichobezoar, making a psychiatric evaluation of paramount importance.
