[Bone loss owing to inflammatory bowel disease: prospective study, 50 cases].

Aims: To evaluate the prevalence of osteoporosis during inflammatory bowel disease (IBD) and to determine the risk factors.

Methods: We conducted a prospective study that includes IBD patients. For all patients, bone mineral density was measured by dual-energy X-rays absorptiometry.

A gastric collision tumor composed of adenocarcinoma and gastrinoma: case report.

Background: Collision tumors of the stomach are exceedingly rare, with only six previous reported instance in which adenocarcinoma of the stomach were found in association with carcinoid tumor. Only in one case the adenocarcinoma was associated with a gastrinoma.

Aim: we report the second case of Collision tumor between adenocarcinoma and gastrinoma.

[Eosinophilic gastroenteritis with ascites: a case report].

Background: Eosinophilic gastroenteritis is a rare pathology, of undetermined etiology which incidence is in increase. It is characterized by eosinophilic infiltration of the wall of the gastrointestinal tract. Clinical manifestations are very variable and the severity of the clinical picture depends on the site involved and the wall layers infiltrated.

[Acute pancreatitis revealing Behçet disease].

We report here a case of acute pancreatitis revealing Behcet's disease in an 18-year-old woman. Pancreatitis was due to ischemia secondary to severe abnormalities of the celiac trunk arteries with pseudo-aneurysms. The outcome was favourable after the administration of corticosteroids and cyclophosphamide.

Macrocystic pancreatic cystadenoma: The role of EUS and cyst fluid analysis in distinguishing mucinous and serous lesions.

Background: Benign pancreatic serous cystadenoma usually is morphologically distinguishable from mucinous cystadenomas, which require resection because of their malignant potential. A macrocystic variant of serous cystadenoma recently has been described, rendering this important distinction more difficult. The aim of this study was to determine the EUS and tumor marker characteristics of mucinous cystadenoma compared with macrocystic serous cystadenomas.

[Corticosteroid dependence and resistance in Crohn's disease: prevalence and predictive factors].

The aim of our study was to determine the prevalence of corticosensibility, corticodependency, and corticoresistance in patients with Crohn's disease. Ninety four treatments with corticoids were prescribed to the patients during the follow-up. The rates of corticosensibility, corticodependency, and corticoresistance were 66%, 16%, 18%.
