FACTORS ASSOCIATED WITH A HIGHER NUMBER OF ESOPHAGEAL DILATIONS IN CHILDREN WITH A HISTORY OF ALKALINE INGESTION.

Background: Children who experience alkaline injury are at risk for the development of esophageal strictures and the need for esophageal dilations.

Objective: We aimed to assess predictors for a higher number of esophageal dilatations in children following alkali ingestion.

Methods: Single-center retrospective cohort study including children who underwent esophagogastroduodenoscopy (EGD) after alkali ingestion.

Outcomes and factors associated with tolerance in infants with non-IgE-mediated cow's milk allergy with gastrointestinal manifestations.

Objectives: To evaluate outcomes of oral food challenge (OFC) test to assess tolerance in infants with non-IgE-mediated cow's milk allergy (CMA) with gastrointestinal manifestations and explore clinical data predictive of these outcomes.

Methods: Single-center retrospective study including infants (age < 12 months) who were referred for CMA between 2000 and 2018 and underwent OFC on follow-up. A univariate logistic regression test was performed to evaluate variables associated with the outcomes of the follow-up OFC test.

SYMPTOMATIC CHOLELITHIASIS AS THE PRESENTATION OF PEDIATRIC PRIMARY SCLEROSING CHOLANGITIS - CASE SERIES AND LITERATURE REVIEW.

Background: Primary sclerosing cholangitis (PSC) is a rare hepatobiliary disorder, whose etiology remains not fully elucidated. Given how rare PSC is in childhood, until the recent publication of a multicenter international collaboration, even data on its characteristics and natural history were scarce. Symptomatic cholelithiasis has not been previously reported as the presentation of PSC.
