Metabolomic comparison of postprandial distress syndrome patients with and without duodenal eosinophilia.

Objective: In functional dyspepsia patients, duodenal mucosal eosinophilia has been associated with early satiety but is not present in all patients suggesting varied pathways to symptom generation. The objective of the current study was to explore metabolic differences comparing those with duodenal mucosal eosinophilia to those without eosinophilia.

Methods: This study was conducted utilizing an existing biorepository.

Presence of Increased Mast Cells in Infants and Children with Volume and Variety Limited Intake.

Background: Reports indicate patients with feeding difficulties demonstrate signs of inflammation on biopsies, notably eosinophilia, but it is unknown whether mast cell density contributes to variety or volume limitation symptoms. The aim of our study was to evaluate eosinophil and mast cell density of EGD biopsies in pediatric patients with symptoms of decreased volume or variety of ingested foods.

Methods: We conducted a single-center, retrospective chart review of EMRs for all new feeding clinic patients between 0 and 17 years of age.

Colonic mucosal eosinophilia in children without inflammatory bowel disease.

Children undergoing colonoscopy and mucosal biopsies may show increased colonic mucosal eosinophils, which may or may not be associated with inflammatory bowel disease. There is not much clinical data on American children who have isolated increased colonic mucosal eosinophils. We sought to study the clinical correlates of children without inflammatory bowel disease who show increased mucosal eosinophils to understand their clinical presentation, etiological associations, and outcome.

Mucosal eosinophils, mast cells, and intraepithelial lymphocytes in youth with rumination syndrome.

Background: Rumination syndrome has been associated with increased duodenal eosinophils and intraepithelial lymphocytes in adults. The aims of the current study were to assess densities of antroduodenal eosinophils and mast cells and duodenal intraepithelial lymphocytes in youth with rumination syndrome and to compare cell densities in those with and without abdominal pain or early satiety.

Methods: Twenty-eight youth fulfilling Rome IV criteria for rumination syndrome who had undergone endoscopy were identified and compared to 10 controls.

The relationship between mucosal inflammatory cells, specific symptoms, and psychological functioning in youth with irritable bowel syndrome.

Both mucosal inflammation and psychologic dysfunction have been implicated in irritable bowel syndrome (IBS). While some relationships between inflammation (mast cells and eosinophils) and depression have been reported in adults with IBS, relationships between inflammation and psychologic function have not been studied in children and adolescents. The aims of the current study were to: (1) assess densities of colonic mast cells, eosinophils, and TH17 cells in youth with IBS; and, (2) explore relationships between these cells and specific IBS symptoms and psychologic functioning.

A cross-sectional study of nausea in functional abdominal pain: relation to mucosal mast cells and psychological functioning.

Background: Nausea is a common symptom in youth with chronic abdominal pain. The aims of the current study were to assess: 1) the frequency of nausea in patients with functional dyspepsia (FD) and irritable bowel syndrome (IBS), respectively, as defined by Rome IV criteria; and, 2) relationships between nausea and mucosal inflammation as defined by antral and duodenal eosinophil and mast cell densities. A secondary aim was to assess relationships between nausea and other gastrointestinal symptoms, non-gastrointestinal somatic symptoms, and psychological dysfunction.

Colonic mucosal inflammatory cells in children and adolescents with lactase deficiency.

Introduction And Objectives: Many of the symptoms of patients with lactose intolerance are due to fermentation of undigested lactose in the colonic lumen, which may also lead to inflammatory cell changes in the colonic mucosa. The objective of our project was to understand the histopathological changes involving infiltration of eosinophils and mast cells in the colonic mucosa of children with lactase deficiency (LD).

Methods: In this retrospective study we studied colonic mucosa of children and adolescents with LD to determine if any pathological changes or inflammatory cell changes were present.

Mucosal Th17 Cells Are Increased in Pediatric Functional Dyspepsia Associated with Chronic Gastritis.

Background: Chronic gastritis is a common histologic finding in children with functional dyspepsia (FD). While Th17 cells have been implicated in other forms of gastritis, they have not been evaluated in chronic gastritis.

Aims: The aim of the current study was to assess Th17 cells in children with FD with and without chronic gastritis.

Histopathological changes in the gastroduodenal mucosa of children with functional dyspepsia.

Introduction And Objective: Functional dyspepsia (FD) is a functional gastrointestinal disorder that affects a significant number of children presenting with chronic abdominal pain. A high proportion of these children undergo endoscopy to obtain mucosal biopsies which, by standard criteria, generally do not identify a clear explanation for symptoms. We undertook this study of children diagnosed with FD to elucidate the histopathological changes of gastroduodenal mucosa and to describe mast cell and eosinophil densities.

An observational study of headaches in children and adolescents with functional abdominal pain: Relationship to mucosal inflammation and gastrointestinal and somatic symptoms.

Headaches and abdominal pain are among the most common pediatric pain conditions. Mast cells have been implicated in the pathophysiology of migraines, as well as functional dyspepsia (FD) and irritable bowel syndrome (IBS). The primary aims of the current study were to assess headache prevalence in patients with FD and to assess the association between headaches and mucosal mast cells and eosinophils.

A Brief Report of Immunohistochemical Markers to Identify Aggressive Hepatoblastoma.

Hepatoblastoma (HB) is the most common malignant liver tumor in children. Although survival of patients has improved significantly over the last 2 decades, a significant number of patients do not respond to standard chemotherapy. We conducted a pilot study to understand if there was immunophenotypic difference between tumors that respond well to chemotherapy versus that do not.

Symptoms and subtypes in pediatric functional dyspepsia: relation to mucosal inflammation and psychological functioning.

Objectives: The aim of the present study was to explore relations between antral or duodenal inflammatory cells and aspects of psychological functioning with clinical symptom presentation in children with functional dyspepsia (FD), as well as to determine whether histologic inflammation and/or psychopathology are differentially associated with FD subtypes as defined by the Rome II and Rome III criteria.

Patients And Methods: One hundred pediatric patients with dyspepsia completed a standardized history and physical examination at initial evaluation. Patients and parents also completed a measure of psychological functioning.

Antral inflammatory cells, gastric emptying, and electrogastrography in pediatric functional dyspepsia.

The aims of the current study were to determine the activation states of antral eosinophils and mast cells and to evaluate the interactions of antral inflammatory cells with gastric emptying and electrogastrography (EGG) in 30 pediatric patients with functional dyspepsia. Eosinophil degranulation was moderate in 42% and extensive in 54% of patients. Mast cell degranulation was > 50% in 81% of patients.

Congenital lipoblastoma of the scalp.

Lipoblastoma is a unique tumor of infancy and early childhood that can occur congenitally. It commonly occurs in trunk and extremities, but also rarely in head and neck. We have not encountered any report of congenital lipoblastoma of scalp in published literature.

Umbilical cord lesions in early intrauterine fetal demise.

Context: The cause for intrauterine fetal demise (IUFD) occurring in early gestation in a high percentage of spontaneous abortions is unknown.

Objective: To determine the association, if any, of umbilical cord abnormalities with early IUFD.

Design: All cases of IUFD occurring within 16 weeks of gestation that presented to our hospitals between August 1998 and July 2001 were prospectively studied.
