Dramatic Increase in Incidence of Ulcerative Colitis and Crohn's Disease (1988-2011): A Population-Based Study of French Adolescents.

Objectives: Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period.

Methods: Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011.

[Severe varicella infection during treatment with infliximab for Crohn's disease].

Immunosupressive agents have improved the treatment of severe Crohn's disease. Infliximab is increasingly used in the treatment of Crohn's disease refractory to the usual treatment or with fistulas. However, there is a risk of infection and benign viral infections can became severe.

Acute hepatitis due to buprenorphine administration.

Background: Buprenorphine, a synthetic molecule derived from thebaine, has been commercialized in France since 1987 as a substitute treatment for pharmacodependence on opiates. Hepatotoxicity is poorly documented, since only few cases of hepatic injury have been reported.

Methods: We report seven cases of acute cytolytic hepatitis due to buprenorphine.

Autoimmune hepatitis and systemic sclerosis: a new overlap syndrome?

Objective: We report the cases of two patients with the complete CREST variant (calcinosis, Raynaud's phenomenon, oesophageal dysmotility, sclerodactyly, telangiectasia) of systemic sclerosis (SSc) who developed autoimmune hepatitis.

Results: Our findings suggest that autoimmune hepatitis can be considered to be one of the liver manifestations associated with SSc. Our data also indicate that, because liver involvement may precede skin manifestations, evaluation for SSc is appropriate when autoimmune hepatitis is noted, and that the evaluation should include clinical examination, testing for antinuclear antibodies (especially for anticentromere antibodies) and nailfold capillaroscopy.
