Is transmural healing better than mucosal healing in pediatric Crohn's disease?

Background: Limited data exist on the long-term benefits of transmural healing (TH) in pediatric Crohn's disease (CD).

Aims: To evaluate outcomes children with CD achieving TH compared to those with mucosal healing (MH) and no healing (NH).

Methods: Retrospective, single-center study including children with CD undergoing magnetic resonance enterography (MRE), ileocolonoscopy, and/or capsule endoscopy within a three-month interval.

Inter-Rater Disagreements in Applying the Montreal Classification for Crohn's Disease: The Five-Nations Survey Study.

Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.

Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.

Clusters of Disease Activity and Early Risk Factors of Clinical Course of Pediatric Crohn's Disease.

Background: This study aimed to define clusters of disease activity and prognostic factors of disease course in a well-characterized cohort of children with Crohn's disease (CD).

Methods: All patients from the SIGENP IBD (Italian Society of Pediatric Gastroenterology Hepatology and Nutrition Inflammatory Bowel Disease) registry with a 5-year follow-up and 6-monthly evaluation were included. Active disease was defined for each semester as follows: clinical activity (weighted Pediatric Crohn's Disease Activity Index ≥12.

SHH medulloblastoma and very early onset of bowel polyps in a child with hamartoma tumor syndrome.

Phosphatase and tensin homolog () hamartoma tumor syndrome (PHTS) is a cancer predisposition syndrome characterized by an increased risk of developing benign and malignant tumors, caused by germline pathogenic variants of the tumour suppressor gene. gene variants often present in childhood with macrocephaly, developmental delay, and/or autism spectrum disorder while tumors and intestinal polyps are commonly detected in adults. PHTS is rarely associated with childhood brain tumors with only two reported cases of medulloblastoma (MB).
