Background: Eosinophilic esophagitis (EoE) afflicts both children and adults. It has been debated whether pediatric EoE and adult EoE represent different disease entities. The objectives of this study were to determine whether the blood eosinophil molecular pattern of children with EoE is (i) distinct from that of healthy children; and (ii) different from that of adults with EoE.
Methods: Blood eosinophils from children and adults with EoE, and healthy controls, were analyzed with flow cytometry regarding levels of CD23, CD44, CD54, CRTH2, FOXP3, and galectin-10. Eosinophil FOXP3 and galectin-10 mRNA levels were determined by qPCR. The data were analyzed using a multivariate method of pattern recognition.
Results: An eosinophil molecular pattern capable of distinguishing children with EoE from control children was identified. A smaller fraction of eosinophils from children with EoE expressed CD44 and a larger fraction expressed CRTH2 than the controls. Eosinophils from children with EoE also had higher levels of galectin-10 mRNA and lower levels of FOXP3 mRNA. The eosinophils from children with EoE had lower levels of surface CD54 and of FOXP3 mRNA compared with the eosinophils from the adult patients. A key finding was the detection in healthy individuals of age-related differences in the levels of several eosinophil markers.
Conclusions: Children with EoE can be distinguished from healthy children based on the molecular patterns of their blood eosinophils. Age-related physiologic differences in eosinophil molecular patterns may partly explain the different blood eosinophil phenotypes in children vs adults with EoE.

Objectives: The literature shows connections between maternal depression, children's executive function (EF), and emotional overeating (EOE). This study examined the interplay between maternal postpartum depression, EF, and EOE. We hypothesized that higher levels of postpartum depression would lead to lower inhibition and emotional control and higher levels of EOE.

Purpose: Eosinophilic esophagitis (EoE) is the most well-known eosinophilic gastrointestinal disorder (EGID) characterized by the presence of a high number eosinophils within the esophageal epithelium and the clinical signs. Biopsies of patients with suspected EoE may not show a high number of eosinophils, however the presence of granules may help with the diagnosis. This study aims to evaluate the presence of cell-free eosinophil granules in the esophageal tissue of patients with suspected and confirmed EoE to accelerate the diagnosis and treatment of patients with low eosinophil count.

Background: Eosinophilic esophagitis (EoE) has been described as a chronic allergen/immune-mediated disease characterized by symptoms of esophageal dysfunction and eosinophilic infiltration of the mucosa.
Summary: Over the past decades, EoE has been increasingly recognized in various geographical areas with a high socioeconomic development (mostly industrialized countries) and has evolved from an unknown to a clinically distinct disease with increasing prevalence and incidence. An average age at diagnosis between 30 and 50 years and a male predominance have been consistently observed.

Purpose: Eosinophilic esophagitis (EoE), a chronic immune-mediated progressive disease, causes dysphagia, food impaction, abdominal pain, vomiting, and heartburn. EoE requires long-term monitoring and can affect quality of life owing to its symptoms and associated emotional and social burden. This study aimed to understand patients' experiences with EoE.

Purpose: To study the treatment and outcomes of children with retinoblastoma (RB) with extraocular tumor extension (RB-EOE) and compare them with RB without extraocular tumor extension (RB-w/o-EOE).
Design: Multicenter intercontinental collaborative prospective study from 2017 to 2020. RB-EOE cases included those with overt orbital tumor extension in treatment-naive patients.
