OBJECTIVES:Early rebleeding rate after endoscopic therapy with double balloon enteroscopy (DBE) of hemorrhagic small bowel vascular lesions (SBVL) varies between 10 and 50%. In recent reports, long-term follow-up of patients have been described but rebleeding risk factors are still not well established. The aim of the current study was to identify long-term(More)
BACKGROUND We have assessed the long-term efficacy and safety of a combination therapy of interferon alpha-2b (IFN) and ribavirin (RBV) for the treatment of severe chronic hepatitis C in co-infected HIV-seropositive patients in an open prospective study. METHODS Fifty-one patients were treated for 12 months. Mean baseline CD4 cell count, alanine(More)
The present study was designed to evaluate the effect of neural response telemetry (NRT)-based cochlear implant (CI) programming versus behavioral-based programming on electrical stimulation parameters (MAP) threshold (T) and comfortable (C) levels and speech perception abilities in young children, during the first year of implant use. Ten congenitally deaf(More)
BACKGROUND AND STUDY AIMS The aim of the study was to assess the feasibility, diagnostic yield, and interobserver agreement of capsule endoscopy in the investigation of patients with obscure or occult gastrointestinal bleeding. PATIENTS AND METHODS A total of 64 consecutive patients with occult bleeding (31 %) or overt bleeding (69 %) were assessed using(More)
In this study, colonic biopsy specimens from 87 subjects (37 men and 50 women; mean age 51 +/- 14 years) were investigated by a new method of quantitation morphometric analysis. Subjects were classified in 3 groups: I, control group (25 cases); II, constipation and/or abdominal pain (36 cases); III, diarrhea (26 cases). All biopsy specimens were considered(More)
BACKGROUND AND STUDY AIMS In patients who are highly likely to have common bile duct (CBD) stones, it seems necessary to image the biliary tract before laparoscopic cholecystectomy, and endoscopic ultrasonography (EUS) is one way of doing this. The aim of this study was to compare immediate preoperative EUS to intraoperative cholangiography for imaging the(More)
A prospective light and electron microscopic study of repeated endoscopic gastric biopsy specimens obtained from 10 patients presenting at the first examination for long-standing erosive gastritis was performed. In nearly all specimens from 7 patients, spiral bacteria were found in close contact to the surface epithelial cells and associated with active(More)
OBJECTIVE To compare, in a prospective study, results of endoscopic ultrasonography and computed tomography in staging of pancreatic and ampullary carcinoma tumours, assessed surgically. METHOD From January 1990 to May 1993, 37 patients with pancreatic tumours had per-operative endoscopic ultrasonography and computed tomography. All patients underwent(More)
