[Colonic involvement in the Klippel-Trenaunay-Weber syndrome].
We report the case of a 12-year-old boy, diagnosed of Klippel Trenaunay Weber syndrome, with hemangiomas and venous varicosities in the right leg, who complaint about incidental hematochezia. In the colonoscopy some violet and plain angiodysplastic lesions like in the skin, were observed in rectum and distal sigmoid colon. We think this case is interesting, because of the unusual affectation of the gut in this disease and the importance of considering the endoscopic procedures in the evaluation of these patients.

[Dementia caused by bacterial overgrowth in a patient with Billroth II gastrectomy].
We report the case of a patient in the Psychiatric Department who complained of progressive impairment of cerebral functions consistent with dementia, diarrhea and fecal incontinence in the last few months. His medical history included a Billroth II gastrectomy for gastric ulcer. Biochemical tests detected cobalamin deficiency, without megaloblastic anemia, and an abnormal Schilling test that was not due to intrinsic factor deficiency. Once other causes of cobalamin deficiency were ruled out, we considered it as a deficiency disease due to blind loop syndrome. Treatment with parenteral vitamin B complex and long term oral antibiotic therapy allowed the complete and permanent resolution of neurologic and digestive symptoms. We consider this case to be interesting because it shows the existence of curable dementias and the usefulness of taking into account bacterial overgrowth, usually underestimated, as an entity that can produce a variety of disorders.

[Utility of endoscopy in digestive hemorrhage due to vasculitis].
Vasculitides constitute a heterogeneous group of diseases characterized by inflammation of blood vessels. The skin is mainly affected, although the gastrointestinal tract mucosa can also be involved. The contribution of endoscopy in these cases has not been clearly determined. We report three cases of systemic vasculitis (polyarteritis nodosa, Schonlein-Henoch purpura and Behcet's disease) presenting with acute digestive bleeding. Endoscopy was an effective technique for completing the diagnosis and in establishing an effective nonsurgical therapeutic approach in these potentially lethal cases of gastrointestinal hemorrhage.

[Barrett's esophagus].
Barrett's esophagus (BE), a complication of gastroesophageal reflux disease, is the replacement of squamous tissue with specialized intestinal metaplasia. Other noxious factor, as biliary acids, may contribute to the induction of BE. It is a premalignant condition, and adenocarcinoma arises in some cases. An endoscopic surveillance with multiple biopsies is mandatory to detect different grades of dysplasia or intramucosal cancer and allow effective therapy. Since its prevalence is high, current surveillance protocols become expensive and patient's compliance is difficult. The main medical goals are: 1) To stratify individuals without dysplasia as either lower or higher risk, to screen less often those at lower risk. 2) To obtain complete remission or eliminate the risk of cancer and the need for surveillance. Current treatments have not demonstrate complete regression of metaplasia. Recently, new endoscopic approaches to therapy have been developed. Although they remain experimental and larger series are required, initial results are encouraging.
