Ingestion of foreign bodies and caustic substances in children: a narrative review on clinical evaluation and management update

Maria Rogalidou

Clin Exp Pediatr. 2026;69(1):11-21. Published online December 10, 2025

Foreign body and caustic substance ingestion in children aged 1–5 years can feature to severe and, sometimes life-threatening complications. High-risk items include batteries, magnets, and corrosive chemicals. Severity depends on object type, location, and ingestion timing. Prompt diagnosis and early endoscopic intervention are crucial. Individualized management, high clinical suspicion, and parental education are essential to improving outcomes and preventing immediate and long-term complications affecting a child’s quality of life.

Exploring nutritional screening tools for hospitalized children: a narrative review

Pankaj Soni, Amit Agrawal, Gaurav Jadon

Clin Exp Pediatr. 2025;68(12):963-970. Published online October 22, 2025

Malnutrition is frequently identified in hospitalized children, and the use of nutritional screening tools is crucial for assessing their nutritional status during their hospital admission and stay. Common tools include the Pediatric Yorkhill Malnutrition Score, Screening Tool for Assessment of Malnutrition in Pediatrics, and Screening Tool for Risk of Nutritional Status and Growth. However, these tools have varying sensitivities and specificities, and none is recommended for all hospitalized children.

Associations of routine breakfast and napping habits with early adiposity rebound by age 3 years: a population-based cohort study in Japan

Toshifumi Yodoshi

In a population‑based cohort of 74,466 children, 25% experienced early adiposity rebound (AR) by age 3. Daily breakfast and routine napping at 1.5 years were independently associated with lower odds of AR, while obesity at 1.5 years was a strong predictor. These modifiable routines could help delay AR and enable early identification during routine child health checks.

Bridging the gap: autism spectrum disorder in children in the United States and worldwide: a narrative review

Sandhya J. Kadam, Malika Goel

Clin Exp Pediatr. 2025;68(11):852-857. Published online October 2, 2025

The prevalence of autism is increasing worldwide. The United States has the highest numbers, likely due to the availability of better treatment options. However, global disparities exist, especially in low-resource settings in which stigma, underdiagnosis, and limited services hinder care. A coordinated international approach emphasizing early screening, inclusive policies, and culturally sensitive support systems can bridge this gap and improve the outcomes for children with autism and their families worldwide.

Eosinophilic gastrointestinal disorders (EGIDs) often coexist with functional gastrointestinal disorders (FGIDs) and other IgE or non-IgE mediated GI diseases. Diagnosing EGIDs requires a high index of suspicion and a comprehensive approach to differentiate them from conditions like inflammatory bowel disease. Tests such as fecal calprotectin and biopsies aid in severe cases. Maintaining a food diary helps identify triggers for long-term elimination.
