Endovenous ablation of refluxing saphenous and perforating veins.
2017
Abstract. Since the end of the nineties endovenous thermal ablation and more recently non-thermal, non-tumescent techniques have been developed and improved. Until now, because of their favourable side effect profile in conjunction to sustained efficacy, in many countries they already replaced high ligation and stripping in the treatment of refluxing saphenous veins as well as for treatment of perforators and selected tributaries. Now, studies and comparative trials are available with long-term follow-ups for most of the techniques, providing valid data on occlusion and reflux rates, side effect profiles, and health related quality of life.
Acetic acid compared with i-scan imaging for detecting Barrett's esophagus: a randomized, comparative trial.
2013
Background Traditional surveillance in patients with Barrett's esophagus (BE) has relied on random biopsies. Targeted biopsies that use advanced imaging modalities may significantly improve detection of specialized columnar epithelium (SCE). Objective We compared the efficacy of targeted biopsies that used i -scan or acetic acid to random biopsies in the detection of SCE. Design Patients with visible columnar lined epithelium or known BE were randomized at a 1:1 ratio to undergo acetic acid application or i -scan with targeted biopsies. Setting Targeted biopsies were performed based on surface architecture according to the Guelrud classification followed by 4-quadrant biopsies. Patients A t…
European expert opinion on the management of invasive candidiasis in adults
2011
Item does not contain fulltext This report discusses the present status of antifungal therapy and treatment options for candidaemia, considered by experts in the field in Europe. A conference of 26 experts from 13 European countries was held to discuss strategies for the treatment and prevention of invasive candidiasis, with the aim of providing a review on optimal management strategies. Published and unpublished comparative trials on antifungal therapy were analysed and discussed. Commonly asked questions about the management of candidaemia were selected, and possible responses to these questions were discussed. Panellists were then asked to respond to each question by using a touchpad ans…
Randomized Comparative Trial with Ceftizoxime and Cefotaxime in Urinary Tract Infections
1984
Ceftizoxime, a new, semisynthetic, beta-lactamase-resistant cephalosporin, is not metabolized in man and is excreted almost entirely as the original active compound in the urine. The efficacy and safety of ceftizoxime were assessed in 80 patients with acute and chronic urinary infections, with and without associated pathological conditions, in comparison with cefotaxime. Two dosage schedules, 1 g or 0.5 g every 12 h, i.v. or i.m. for 10 days, were adopted according to the severity of each case and to separate randomization tables for each schedule; causal agents were all sensitive to both drugs in vitro. The overall results were excellent. Safety was excellent in almost all cases. In this t…
