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.

[Ultrasound study of gallbladder motility in healthy subjects. Reproducibility of the method and effect of alcohol].

The protective effect of alcohol against cholesterol cholelithiasis has been established in several epidemiologic studies. An impairment of gallbladder motility in gallstone disease has been demonstrated in animals and in man. At a daily dose of 39 g, alcohol reduces the lithogenic index of bile, but its effect on gallbladder motility is still debated.

Hepatic oil embolism following lymphography: CT diagnosis.

Hepatic oil embolism following lymphography is reported in a 68-year-old man admitted for chylous ascites associated with recurrent prostatic carcinoma. Abdominal plain radiography, CT, and ultimately liver biopsy strongly support a direct lymphatic pathway and are against the role of lymphaticovenous anastomoses generally advocated to explain this phenomenon.
