Changes in frequency of benign convulsions with mild gastroenteritis and their viral causes before and during the COVID-19 pandemic: a single-center study   (2,536 times)
Hyejin Na, Sanghoon Lee, Seo Hee Kim, Young Ok Kim
Clin Exp Pediatr. 2024;67(4):213-220.   Published online March 19, 2024
Question: Did coronavirus disease 2019 (COVID-19) affect the frequency, seasonal variation, or virus type of benign convulsions with mild gastroenteritis (CwG)?
Findings: We compared 41 cases of CwG before and during the COVID-19 pandemic. After March 2020, frequency did not change significantly (18 patients vs. 23 patients), seasonal variation was lost, and number of cases of enteric adenovirus-associated CwG increased (1 cases vs. 7 cases).
Meaning: The COVID-19 pandemic affected CwG.

Incidence, causative organisms, and risk factors of bloodstream infections in pediatric liver transplant patients: a systematic review   (2,529 times)
Mohamad Shieb, Rand Hasanain, Zara Arshad, Faisal A. Nawaz, Rahul Kashyap, Eric J. Stern
Clin Exp Pediatr. 2024;67(9):427-434.   Published online April 5, 2024
The overall incidence of bloodstream infections was 23.5%. Gram-negative organisms occur at a much higher rate in pediatric liver transplant recipients then that the general pediatric population. However, when comparing pediatric and adult liver transplant recipients Gram-positive organisms occur with a much higher rate in the pediatric population highlighting the importance of early and broad spectrum antimicrobial coverage when bloodstream infections are suspected.

Hee-Jeong Kang
Clin Exp Pediatr. 2024;67(6):294-295.   Published online May 21, 2024
· Plagiocephaly is characterized by the asymmetrical shape of a baby’s head.
· Since positional plagiocephaly is associated with developmental delay and further musculoskeletal problems, early detection allows for timely intervention and prevents worsening of the condition.
· Pediatricians can educate parents about proper head positioning and encourage supervised tummy time during awake hours.

Construction and validation of predictive models for intravenous immunoglobulin–resistant Kawasaki disease using an interpretable machine learning approach   (2,448 times)
Linfan Deng, Jian Zhao, Ting Wang, Bin Liu, Jun Jiang, Peng Jia, Dong Liu, Gang Li
Clin Exp Pediatr. 2024;67(8):405-414.   Published online July 23, 2024
Question: Is there a reliable model to predict intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD)?
Finding: We constructed 5 machine learning models to predict IVIG-resistant KD. Extreme gradient boosting (XGBoost) model was superior to logistic, support vector machine, light gradient boosting machine and multiple layers perception models. The SHAP (SHapley Additive exPlanations) value interpreted the contribution of each feature in XGBoost model.
Meaning: XGBoost model showed the excellent performance to predict IVIG-resistant KD with explainable and visualizable machine learning algorithm.

Evaluation of Bak and Bcl-Xl gene expression among pediatric patients with acute primary immune thrombocytopenia   (2,448 times)
Amira Zaki Badawy, Samia Hassan Kandel, Iman Aly Ahmedy, Mahmoud Ahmed Elhawy, Sally Mohamed El-Hefnawy, Dina Fouad Sief El-Nasr Zidan, Hanan Hassan El-sheity
Clin Exp Pediatr. 2025;68(11):901-908.   Published online August 6, 2025
The B-cell lymphoma protein 2 family proteins Bak and Bcl- Xl, important markers of apoptosis, may contribute to primary immune thrombocytopenia (ITP). Thus, their expression may serve as biomarkers for the diagnosis and monitoring of pediatric ITP. Targeting these pathways may improve platelet survival, particularly in treatment-resistant cases. Personalized treatments based on apoptotic profiles can optimize therapy and reduce the unnecessary use of immunosuppressive drugs.

Mara O. Zuiderwijk, Sophie Groene, Enrico Lopriore, Vincent Bekker, Michiel H.D. Schoenaker
Clin Exp Pediatr. 2026;69(7):572-581.   Published online May 12, 2026
Question: As small for gestational age (SGA) neonates are more susceptible to infections, we hypothesized that their complete blood count and leukocyte differentiation might be affected.
Finding: The counts of multiple blood cells of extreme SGA neonates were affected as illustrated by multivariate analyses, which showed significant decreases in neutrophil, monocyte, lymphocyte, and thrombocyte counts.
Meaning: The mechanisms underlying this phenomenon and its clinical effects require further elucidation.

Clin Exp Pediatr. 2026;69(3):274-281.   Published online January 20, 2026
Question: Can the revised Japanese classification predict severe bronchopulmonary dysplasia (BPD) early in preterm infants?
Finding: Small for gestational age and bubbly/cystic chest radiographic patterns were independently associated with severe BPD, and subtypes I and III showed particularly strong associations.
Meaning: This classification may facilitate early risk stratification and guide timely supportive strategies to prevent progression to severe BPD.

Ga Won Jeon
Clin Exp Pediatr. 2025;68(7):486-488.   Published online April 16, 2025
Intermittent sigh breaths during high-frequency oscillatory ventilation can improve ventilation and oxygenation by enhancing lung recruitment. Although research on this approach in newborn infants is limited, some published studies suggest that sigh breaths are generally applied at a rate of 2–3 breaths/min with an inspiratory time of 0.5–1 second and pressure of current mean airway pressure + 5 cmH2O (maximum, 30 cmH2O).

Linking pediatric obesity to youth-onset type 2 diabetes: integrated longitudinal and cross-sectional evidence from population-based studies worldwide   (2,303 times)
Ashraf T. Soliman, Fawzia Alyafei, Nada Alaaraj, Noor Hamed, Shayma Mohamed, Ahmed Elawwa
Clin Exp Pediatr. 2026;69(8):622-635.   Published online July 20, 2026
Pediatric obesity and youth-onset type 2 diabetes have increased simultaneously across 6 continents over the last 25 years. Approximately 75% of affected youths are obese at diagnosis, beta-cell declines occur rapidly, and microvascular complications occur early. Glucagon-like peptide-1 receptor agonists and bariatric surgery achieve meaningful weight loss and glycemic improvement; however, the primary prevention of childhood obesity remains the most powerful strategy for arresting this epidemic.
