The possible role of Saccharomyces boulardii, a nonpathogenic yeast with beneficial effects on the human intestine, in the maintenance treatment of Crohn’s disease has been evaluated. Thirty-two patients with Crohn’s disease in clinical remission (CDAI < 150) were randomly treated for six months with either mesalamine 1 g three times a day or mesalamine 1 g(More)
OBJECTIVES Alterations in mucin (MUC) glycosylation and expression have been described in cancer. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) can provide material for molecular biology analysis. This study assessed the feasibility of evaluating MUC expression from material obtained by EUS-FNA and studied the profile of MUC expression in(More)
We assessed both the effectiveness of two Helicobacter pylori (Hp) eradication triple therapies and the usefulness of serology in the follow-up. Fifty patients with active or scarred duodenal ulcer were randomized to lansoprazole or omeprazole for 1 to 4 weeks, with clarithromycin 250 mg twice a day and tinidazole 500 mg twice a day for the first week.(More)
BACKGROUND Endoscopic Ultrasound-guided Fine Needle Aspiration (EUS-FNA) is effective for obtaining biopsy specimens from pancreatic lesions. AIM To determine the frequency and severity of complications after EUS-FNA of solid and cystic pancreatic lesions in a single centre large series of patients. PATIENTS AND METHODS From January 2005 to December(More)
BACKGROUND/AIM The presence of on-site cytopathologists improves the diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic masses; however, on-site cytopathologists are not available to all endoscopic units. We hypothesized that experienced cytotechnicians can accurately assess whether an on-site pancreatic mass(More)
BACKGROUND/AIM Several diagnostic tests are available for evaluating Helicobacter pylori (Hp) infection: histological examination, culture of gastric biopsy specimens, rapid urease test, urea breath test and serology. A recently marketed direct enzyme immunoassay (HpSA) detects Hp antigen in stool samples. The aim of our study was to evaluate overall(More)
AIM To compare the sensitivity and specificity of two imaging techniques, endoscopic ultrasound (EUS) and magnetic resonance imaging (MRI), in patients with rectal cancer after neoadjuvant chemoradiation therapy. And we compared EUS and MRI data with histological findings from surgical specimens. METHODS Thirty-nine consecutive patients (51.3% Male; mean(More)
dergo an endoscopic ultrasound−guided fine−needle aspiration (EUS−FNA) of a le− sion in the posterior region of the rectum. Informed consent was obtained. EUS, per− formed with a linear probe (3830UT, Pen− tax, Hamburg), confirmed a hypoechoic lesion with well−defined margins at 10 cm from the anal sphincter, between the posterior region of the rectum and(More)
AIM Endometriosis is defined by the presence of endometrial glands and stroma outside the uterus. The disease causes pelvic pain, dysmenorrhea, dyspareunia, dyschezia and urinary symptoms. The aim of this study was to assess the usefulness of endoscopic ultrasound (EUS) and elastosonography for detecting rectosigmoid endometriosis and to compare the(More)
