Introduction: Ectodermal dysplasias (EDs) are a large group of rare and complex genetic disorders, affecting the development of two or more ectodermal structures. Hypohidrotic ED (HED) is the most frequent ED's phenotype and is characterized by hypodontia, hypotrichosis, and hypo/anhidrosis, leading to heat intolerance and hyperthermia.
Case Presentation: We report a case of a 2-year-old girl with hair and teeth abnormalities associated with severe digestive symptoms responsible for failure to thrive. Genetic analysis by mass sequencing in parallel on a 4,867-gene panel was performed in duo (index case and her mother). The girl showed the presence of a new de novo c.100dupG variant in responsible for HED associated with a diagnosis of food protein-induced enterocolitis syndrome (FPIES).
Conclusion: We describe a patient with HED and a new variant associated with a diagnosis of FPIES, both implicating increased intestinal permeability. The inclusion of FPIES as a possible digestive symptom of HED can be suggested, although it may occur only in a context of atopy.

Background: Management of patients with food allergies is complex, especially in cases of patients with multiple and potentially severe food allergies. Although international guidelines exist for food allergy management, the role of the allergist in the decision-making process is key.
Objective: Our aim was to investigate the management patterns and educational needs of practicing allergists treating patients with food allergies.

Background: Reintroduction of offending food in pediatric patients affected by Food Protein-Induced Enterocolitis Syndrome (FPIES) is carried out in hospitals with Oral Food Challenge (OFC), which leads to long waiting time and increases the societal burden of medical cost and human resources.
Objective: The aim of the study is to assess severity trend of acute FPIES adverse reactions over time in the same patient for possible outpatient or home reintroduction of offending food.
Methods: All children (<18 years-old) with a diagnosis of acute FPIES referred to 2 Italian pediatric allergy clinics were retrospectively enrolled.

Food protein-induced enterocolitis syndrome (FPIES) is a non-immunoglobulin E (IgE)-mediated food allergy. IgE sensitization to the causative food is often not observed, and the rate of sensitization to other common foods is not exceptionally high. This report discusses the case of a boy being followed up for FPIES due to egg yolk, who developed a buckwheat allergy during the disease.

: Food protein-induced allergic proctocolitis (FPIAP) is a non-IgE-mediated food allergy, usually presenting as bloody stools in breastfed, well-appearing, and regularly growing infants. The aim of our study was to describe the clinical features of Italian infants affected by FPIAP and their management and natural history in a real-life setting. : A retrospective, observational study was performed at two tertiary pediatric hospitals (Florence and Trieste), including FPIAP-diagnosed infants between 2012 and 2022.
