BACKGROUND AND AIM In high or moderate risk populations, periodic surveillance of patients at risk of progression from gastric precursor lesions (PL) to gastric cancer (GC) is the most effective strategy for reducing the burden of GC. Incomplete type of intestinal metaplasia (IIM) may be considered as the best candidate, but it is still controversial and(More)
Acute hepatitis C virus infection produces clinical and biochemical features that is non-specific and indistinguishable from those caused by other hepatotropic viruses. The specific diagnosis of acute hepatitis C virus infection is based on the detection of serum RNA-HCV through a technique of PCR whose result will be positive after 1-2 weeks of the initial(More)
Due to international migration, Chagas disease, endemic in Latin America, has become more common in non-endemic areas.

retrieve proximally migrated pancreatic stents [1,2]. The lasso technique involves inserting a guide wire through the lumen of the migrated stent followed by insertion of a partially opened polypectomy snare over the wire to grasp the stent [3]. We present the case of a 72-year-old woman with recurrent acute biliary pancreatitis, who underwent endoscopic(More)

BACKGROUND An association between Helicobacter pylori infection and heart disease has been suggested. A potential mechanism may be inflammation-induced atherogenic changes of lipoproteins, but epidemiological studies have provided conflicting results. METHODS In a prospective multicentre study, 830 patients submitted for endoscopy and H. pylori testing(More)
