Recurrent acute pancreatitis in pediatrics: characteristics and risk factors.

Recurrent acute pancreatitis (RAP) affects 15-36% of children with acute pancreatitis (AP) and may progress to chronicity. To determine the etiology and evolution of RAP, a descriptive retrospective cohort study was conducted in patients aged 1-18 years. Twelve patients with RAP were included out of 79 with AP, and demographic, etiological, clinical, analytical, and imaging data were collected.

Differences in rectoanal inhibitory reflex duration between patients with refractory functional constipationand myelomeningocele.

IgA anti-tissue transglutaminase antibodies and IgG antibodies against deamidated gliadin peptides as predictors of celiac disease.

Objective: To compare the performance of IgA anti-tissue transglutaminase antibodies (IgA anti-tTG), IgA anti-endomysial antibodies (IgA EMA), and IgA/IgG antibodies against deamidated gliadin peptides (IgA/IgG anti-DGP) for the diagnosis of celiac disease.

Methods: Descriptive study in patients with celiac disease. Anti-DGP (IgA/IgG), IgA EMA, IgA anti-tTG antibodies were measured and an intestinal biopsy was done.

Unintentional ingestion of 60% hydrogen peroxide by a six-year-old child.

Ingestion of industrial-strength hydrogen peroxide is rare. Fatal outcomes have been reported with solutions of 35%. We report a six-year-old boy who unintentionally ingested an unknown quantity of hydrogen peroxide with a concentration of 60%.
