Annals of Surgery; 213:627-634 A prospective randomized trial was conducted of preoperative endoscopic sphincterotomy and surgery (ES&S) or surgery alone (SA) in 52 patients with cholecystolithiasis and choledocholithiasis that were candidates for electiv...

Thrombosis and hemocyte damage are the main problems of applied non-coated biomaterials to cardiac surgery that remain unsolved. The present study is aimed at the chemical modification of polyvinyl chloride (PVC) for applications in cardiac surgery and the biological property assessment of modified PVC. Sodium alginate (SA)/heparin (HEP) composites were covalently immobilized onto the surface o...

AIMS To compare the quality of vision in pseudophakic patients implanted with aspherical and spherical intraocular lenses (IOLs). MATERIALS AND METHODS Randomized prospective longitudinal intrapatient comparison between aspherical and spherical IOLs performed on 22 patients who underwent bilateral cataract surgery. Best corrected visual acuity, subjective contrast sensitivity, Strehl ratio an...

This study was conducted to assess the incidence of abnormalities of ventricular depolarization (late potentials) in children with sinus rhythm after open heart surgery and their relation to spontaneous ventricular tachycardia. Open heart surgery, particularly operations involving ventriculotomy, may predispose patients to the development of ventricular tachycardia (VT) or ventricular fibri...

INTRODUCTION An accurate differential diagnosis between single adenoma (SA) and multiglandular disease (MGD) remains difficult in Technetium-99m sestamibi scintigraphy (MIBI)-negative patients with primary hyperparathyroidism (PHPT). The aim of the present study was to evaluate the minimally invasive parathyroidectomy (MIP) in patients with PHPT. METHODS Clinical records of 48 patients who un...

purpose: to evaluate the effect of laser in situ keratomileusis (lasik) on stereoacuity (sa). methods: in this prospective study, 200 patients scheduled for lasik were evaluated for sa preoperatively and one week and one and three months postoperatively by random dot test. patients with preoperative sa worse than 480 sec/arc were excluded. results: patients included 138 female (69%) and 62 male...

Agents enabling tumor staging are valuable for cancer surgery. Herein, a targetable sialic acid-armed near-infrared profluorophore (SA-pNIR) is reported for fluorescence guided tumor detection. SA-pNIR consists of a sialic acid entity effective for in vivo tumor targeting and a profluorophore which undergoes lysosomal acidity-triggered fluorogenic isomerization. SA-pNIR displays a number of adv...
