Liver metastasis secondary to primary mesenteric carcinoid.

Carcinoid tumors are rare, slow-growing neoplasms that display neuroendocrine properties. The term carcinoid is generally applied to well-differentiated neoplasms, while neuroendocrine carcinoma is reserved only for poorly differentiated lesions. They can be found throughout the different regions of the gastrointestinal system, although they have predilection for the ileum.

The role of flow cytometry in celiac disease screening using human leukocyte antigen in adult patients with type 1 diabetes mellitus.

Background: Patients with type 1 diabetes mellitus (DM1) have an increased risk of celiac disease (CD). Since CD can be seronegative, more sensible tests for detection are needed. In seronegative patients, CD diagnosis may be difficult because of a lack of specificity.

[High incidence rates of inflammatory bowel disease in Navarra (Spain). Results of a prospective, population-based study].

Introduction: As reflected in the European Collaborative Study on Inflammatory Bowel Disease (1991-1993), differences between northern and southern European countries in the incidence of ulcerative colitis (UC) and Crohn's disease (CD) show a tendency to decrease. No data are available on the current incidence of these diseases in Navarre (northern Spain).

Aim: To determine the present incidence of inflammatory bowel disease (IBD) in Navarra.
