ASSESSING MUCOSAL RECOVERY DURING THE FIRST 15 MONTHS OF ADOPTING A GLUTEN-FREE DIET IN CHILDREN WITH CELIAC DISEASE.

Objective: Determine contemporary rates of early mucosal recovery in children with celiac disease (CeD).

Methods: Multicenter retrospective cohort study in Canada and the United States. Children diagnosed with CeD between 2016 and 2021 who underwent a follow-up biopsy within 15 months of diagnosis were included.

Clinical presentation and factors associated with gluten exposure in children with celiac disease.

Objectives: The prevalence of celiac disease (CeD) is increasing, yet it is still underdiagnosed, in part because of its heterogeneous presentation. Diagnostic criteria are evolving and management with strict adherence to a gluten-free diet is challenging for many. We aimed to characterize the clinical presentation of CeD among a large multicenter cohort of pediatric patients and to identify factors associated with gluten-free diet adherence.

A Clinician's Guide to Gluten Challenge.

Gluten challenge is an essential clinical tool that involves reintroducing or increasing the amount of gluten in the diet to facilitate diagnostic testing in celiac disease (CD). Nevertheless, there is no consensus regarding the applications of gluten timing, dosing, and duration in children. This review aims to summarize the current evidence, discuss practical considerations, and proposes a clinical algorithm to help guide testing in pediatric patients.

The Spectrum of Duodenal Histologic Findings in Patients With Trisomy 21: A Multicenter Study.

Objectives: Patients with Trisomy 21 (T21) commonly have gastrointestinal symptoms and diseases that prompt evaluation with esophagogastroduodenoscopy (EGD). Our objective is to characterize duodenal histological abnormalities in these patients when undergoing EGD. A secondary aim is to explore associations of histologic findings with different therapies.

Intussusception as Rare Presenting Sign of Pediatric Celiac Disease: A Case Series.

Intussusception is the most common cause of gastrointestinal obstruction in children and typically presents with acute abdominal pain. Intussusception usually occurs in children under the age of 3 in the ileocecal region. Over the past 5 years, multiple patients at the Children's Hospital of Philadelphia have been diagnosed with both intussusception and biopsy-confirmed celiac disease (CD).

Repeat Biopsy to Assess Duodenal Healing in Children With Celiac Disease and Eosinophilic Gastrointestinal Disorders.

Unlabelled: The aim of the study was to determine the correlation between duodenal mucosal biopsies and tissue transglutaminase immunoglobulin A (tTG-IgA) levels in pediatric patients with biopsy-confirmed celiac disease (CD) and eosinophilic gastrointestinal disorders (EGID) who have had repeat duodenal biopsies after initiating a gluten-free diet.

Methods: A retrospective chart review was performed of children with CD and EGID seen at the Children's Hospital of Philadelphia between 2003 and 2018. Data collected included duodenal biopsy pathology, celiac serology including tTG-IgA, and symptom reports.

Food allergen triggers are increased in children with the TSLP risk allele and eosinophilic esophagitis.

Objectives: TSLP has been shown to be associated with eosinophilic esophagitis (EoE). Specifically, children with EoE often have the nucleotides AA or AG instead of GG at the single nucleotide polymorphism position RS3806932. Presently, the phenotypic characteristics in EoE children with the TSLP EoE risk allele are unknown.

Eosinophilic Gastrointestinal Disorders.

Eosinophilic esophagitis (EoE) is an atopic disease that is characterized by an isolated infiltration of eosinophils into the epithelium of the esophagus and is triggered by specific allergens. Patients should undergo an upper endoscopy with biopsy after 6 to 8 weeks of treatment with a proton pump inhibitor in order to make the diagnosis of EoE. Eosinophilic gastroenteritis is a pathologic eosinophilic infiltration of any portion of the gastrointestinal tract, and eosinophilic proctocolitis is an eosinophilic infiltration in the colon alone.

Correlation Between Aeroallergen Levels and New Diagnosis of Eosinophilic Esophagitis in New York City.

Objective: The relation between food allergies and eosinophilic esophagitis (EoE) is well established. Aeroallergens may also contribute to the development of EoE; however, there are limited data to support or refute this hypothesis. The objectives of this pilot study were to determine whether there is a seasonal variation in the onset of symptoms and/or diagnosis of EoE and whether these variations correlate with a specific pollen concentration within New York City.

Influence of perinatal factors in short- and long-term outcomes of infants born at 23 weeks of gestation.

Objective: Investigate the influence of perinatal factors on short- and long-term outcomes for infants born at 23 weeks of gestation.

Study Design: This is a retrospective study over a 25-year period (1987-2011) of 87 successfully resuscitated infants at 23 weeks of gestation. We investigated the effects of poor prenatal care, race, gender, chorioamnionitis, antenatal corticosteroids, delivery route/location, low 5-minute Apgar score, birth weight, and multiple births on short- and long-term outcomes.

Predicting behavior of Staphylococcus aureus, salmonella serovars, and Escherichia coli O157: H7 in pork products during single and repeated temperature abuse periods.

Tools for predicting growth of Staphylococcus aureus, Salmonella, and Escherichia coli O157:H7 (THERM; temperature history evaluation for raw meats) have been developed using ground pork and sausage. THERM tools have been tested with three types of pork sausage but not with other pork products or during sequential temperature abuse periods. We conducted inoculation studies (five strains each of S.
