Carcinoid tumors of the duodenum and the ampulla of Vater: current diagnostic and therapeutic approach in a series of 8 patients. Case series.

Aim: To describe the specific characteristics of duodenal/perivaterian carcinoids and to analyze the diagnostic/therapeutic approach.

Material And Methods: Eight patients were included in our study. Symptoms on admission included dyspepsia, upper gastrointestinal (GI) bleeding and anemia.

Acute hyperhomocysteinemia impairs endothelium function in subjects with type 2 diabetes mellitus.

The objective of the present study was to examine the effect of acute, methionine-induced hyperhomocysteinemia (HHCY) on endothelial function and indices of arterial stiffness in subjects with type 2 diabetes mellitus (T2DM). A total of 30 subjects with T2DM, free of macrovascular disease were examined in a crossover study. L-methionine (M) (0.

Diet-induced thermogenesis and substrate oxidation are not different between lean and obese women after two different isocaloric meals, one rich in protein and one rich in fat.

Reduction in diet-induced thermogenesis (DIT) may promote weight gain and maintenance. Data on differences in DIT and macronutrient oxidation between lean and obese subjects are conflicting. In this study, we sought for differences in DIT and macronutrient oxidation between lean and obese women after consumption of 2 different isocaloric meals, one rich in protein and one rich in fat.

Current diagnosis and treatment of gastrointestinal carcinoids in a series of 101 patients: the significance of serum chromogranin-A, somatostatin receptor scintigraphy and somatostatin analogues.

Background/aims: Carcinoids are relatively rare tumors that arise from neuroendocrine cells and have proved to be slow growing malignancies which involve many organs and most frequently the gastrointestinal (GI) tract. Herein we present in this study 101 pts with carcinoid tumors that originated from the GI tract and pancreas. Also, we analyze the clinical and pathological features, pointing out the characteristics of this group of neoplasms and describing our diagnostic and therapeutical approach, in parallel with a brief review of the literature.
