Background: Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy characterized by gastrointestinal symptom onset within 1–4 hours from trigger food ingestion. In the literature, some authors have previously described the possibility that a patient with FPIES may develop an IgE-mediated allergy to the same trigger food, especially cow's milk (CM). Case Presentation: We reported five cases of CM-FPIES converting to IgE-mediated CM allergy presented at our tertiary pediatric Allergy Unit and performed a review of the literature, aiming to characterize the clinical features of patients who are at risk of developing such conversion. Conclusions: This phenomenon raises the question of whether IgE-mediated and non-IgE-mediated allergies represent a spectrum of the same disease and highlights the need for further investigation to understand the pathophysiological mechanisms of this process.

This article discusses cross-sensitization between sesame and other seeds in children with food allergies. Sesame allergy is becoming more prevalent due to its increased presence in our diets. The study found a high rate of cross-sensitization among sesame and other seeds, such as flax, sunflower, and pumpkin seeds. The severity of sesame allergy in children was confirmed, and the role of sesame 11S and 7S globulins in cross-sensitization was highlighted. Further studies are needed to explore the clinical relevance of cross-reactivity among seeds. [Extracted from the article]

This article discusses the impact of educational interventions on the management of anaphylaxis in a pediatric emergency department (PED). The study found that educational interventions were associated with higher rates of epinephrine administration and improved adherence to guidelines. Additionally, these interventions correlated with a higher percentage of children being invited to follow-up visits. However, the study also noted that the administration rate of epinephrine during the post-implementation period was still below optimal standards. The article suggests that further medical educational and training programs should be recommended to address this issue. [Extracted from the article]

Objectives: We aimed to analyze the episodes of esophageal food bolus impaction (EFI) occurred over a time of 15 years in children admitted to a large pediatric emergency department (PED), documenting their clinical presentation, underlying pathology, management, biopsy rate, and follow-up visits. Additionally, to combine our institutional experience with the existing literature, a comprehensive review was conducted., Methods: We reviewed the medical records of all children presenting to our PED with EFI from 2010 to 2024. The comprehensive review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement for systematic reviews. Electronic databases including PubMed/Medline and EMBASE were screened. The data obtained was synthesized to map out the actual status and current literature on pediatric EFI., Results: We identified 54 cases of EFI. Overall, 22 patients (41%) had underlying pathology. Previous episodes were reported in 14 cases (26%). Urgent endoscopy was performed in 31 cases (57%). The presence of underlying pathology was associated with the need for endoscopic removal (p = 0.013), as well as the history of previous episodes (p = 0.016). Biopsies were performed in 14 cases (26%). Pediatric gastroenterologists showed a higher rate of performed biopsies compared to surgeons, as well as higher rate of follow-up visits. An underlying disease was found during later clinical follow-up in 5 out of 54 cases of EFI (9%). A comprehensive review of 16 studies revealed high rates of underlying pathology and low rates of biopsies and follow-up visits among children with EFI., Conclusion: Increased vigilance in identifying underlying pathologies in children with EFI is crucial. The importance of performing biopsies, regardless of prior anatomical conditions, and the need for ongoing follow-up to ensure timely and accurate diagnoses should be addressed through shared protocols., (© 2024 European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition.)
