BACKGROUND Increased levels of P-glycoprotein occur in some osteosarcomas. In this study we determined the relation between P-glycoprotein status and outcome in patients with high-grade osteosarcoma. METHODS P-glycoprotein status was determined immunohistochemically in specimens of osteosarcoma of the extremities (stage II) from 92 patients who were(More)
Abstract Background and aims. We examined the efficacy of cyclic long-term administration of rifaximin, a broad spectrum, poorly absorbable antibiotic, in obtaining symptom relief in a large series of patients with uncomplicated diverticular disease, and compared the incidence of episodes of diverticulitis in the group treated with rifaximin to that in a(More)
Patients with metastatic Ewing's sarcoma of bone have a poor prognosis. A relation between clinical characteristics and presence of metastatic disease at diagnosis in patients with Ewing's sarcoma of bone was investigated. Data from 618 patients [136 (22%) with metastases at diagnosis] registered at the authors' institution between April 1972 and December(More)
BACKGROUND 50% of patients with functional dyspepsia have delayed gastric emptying. Levosulpiride is an orthopramide drug that stimulates gastrointestinal motility. Aim of our study was to evaluate the effect of levosulpiride on symptoms and gastric and gall-bladder emptying, in dyspeptic patients. METHODS Thirty adult patients, treated for 20 days with(More)
BACKGROUND/AIMS The aims of alpha-interferon treatment for chronic viral liver infections are clearance of the virus and healing of the disease. Hepatocellular carcinoma is a complication of viral cirrhosis; but it is not yet known whether treatment of viral cirrhosis with alpha-interferon prevents this complication. METHODS The incidence and the risk(More)
OBJECTIVE:The 13C-urea breath test (13C-UBT) is a safe, noninvasive, and accurate test for the detection of Helicobacter pylori (H. pylori) infection in adults. The aim of this study was to evaluate sensitivity and specificity of 13C-UBT in children using different types of test meal, doses of 13C-urea and breath sampling intervals. As yet, a validated,(More)
BACKGROUND Current knowledge on splanchnic haemodynamics in coeliac disease is limited and incomplete. AIM To evaluate splanchnic arterial and venous blood flow in coeliac disease. METHODS In 22 coeliac (13 untreated, nine treated) patients and in nine healthy subjects the following variables were assessed: vessel diameter and mean flow velocity in(More)
OBJECTIVE: Dieting obese subjects are at risk of developing gallstones. A gallbladder motor dysfunction could have a pathogenetic role. The principal aim of this study was to evaluate the long term effects of two very low calorie diets differing in fat content on gallbladder emptying and gallstone formation in obese subjects.DESIGN AND SUBJECTS: Gallbladder(More)
OBJECTIVES The appearance of gallstone opacification during oral bile acid administration indicates that stones are no longer susceptible to dissolution and represents, therefore, a definitive treatment failure. Ursodeoxycholic acid (UDCA) has been imputed to facilitate gallstone opacification; however, data regarding the comparative occurrence of gallstone(More)
