[Acute abdomen by anisakiasis and globalization].

Objectives: The AA report a case of a patient with acute abdomen caused by intestinal Anisakiasis, a fish-transmitted infection that results from ingestion of raw or improperly cooked fish contaminated by live larvae of Anisakis Simplex, a round worm from the order of Ascaridida.

Material And Methods: A 33-year-old man, presented to the emergency room with severe upper abdominal pain, nausea and vomiting, without fever. The patient revealed that he had eaten pickled anchovies a few days before.

[Intestinal occlusion by ileal carcinoid].

Objective: Ileal carcinoids diagnosis, generally, is late because patients have aspecific symptoms.

Material Of Study: The two cases described presented for a long time peristaltic abdominal pains, vomit episodes and reduction of weight, with negativity of radiologic reports. The first diagnosis was adhesion syndrome produced by previous abdominal surgical operation; just emergency surgical operation executed for intestinal occlusion noticed carcinoids, located into the distal ileum, which infiltrated muscular wall and interested regional lymph nodes.

Circulating gastrin and ghrelin levels in patients with colorectal cancer: correlation with tumour stage, Helicobacter pylori infection and BMI.

Many studies have pointed out a possible role of gut peptides, including gastrin and ghrelin, in the pathogenesis and natural history of gastrointestinal malignancies, one of the most common death cause in the Western world. The objective of this work is to check gastrin and ghrelin serum levels in patients with colorectal cancer according to tumour's location, stage, Helicobacter pylori infection and BMI, in order to understand the two peptides' behaviour through the tumour's natural history and evaluate their assay's use in research and clinical practice. Twenty-nine subjects affected by colorectal cancer and 50 healthy controls were studied.
