Ultrastructural demonstration of histamine in human enterochromaffin like cell granules.

graphic brush cytology has proved negative by using a fine spring-loaded Tru-cut needle Biopty gun (Biopty TM, Radiplast, Uppsala), percutaneously under ultrasound guidance. The use of self expanding metal stents was alluded to in the leading article, and a primary indication would be those patients with nonresectable hilar cholangiocarcinoma in whom good survival might be expected. There is no evidence that the optimum route of insertion for these metal stents is via the transhepatic route, and there are many advantages in placing metal stents endoscopically.

Apports Recents De La Genetique Dans Les Maladies Inflammatoires Intestinales

SummaryIt is clear since many years that the liability to develop inflammatory bowel disease is influenced by genetic factors. Recent progresses in the field of genetic markers and genetic models bring the concept of genetic heterogeneity. This new concept leads us to try to classify different forms of inflammatory bowel disease and could have in the future an impact on the prevention, the follow up and the treatment of these diseases
