This study evaluated cleaning of the dentinal wall after removal of different calcium hydroxide pastes. Sixty-eight single-rooted teeth were prepared using the step-back technique and randomly divided into 4 groups according to medication used: Ca(OH)2 with 0.2% chlorhexidine solution (Group 1), Ca(OH)2 with propylene glycol (Group 2), Ca(OH)2 with antibiotic paste (ciprofloxacin, metronidazole...

BACKGROUND It has been shown that successful reperfusion of the infarct-related artery by thrombolysis can prevent left ventricular dilation after acute myocardial infarction; these beneficial effects were detected from several days to several months after infarction. To date, however, no study has shown that these effects can be demonstrated within hours after the onset of infarction. Furtherm...

Background Late revascularization following a myocardial infarction has questionable clinical benefit. Methods We studied 13 patients with anterior wall myocardial infarction who underwent percutaneous coronary intervention within 2 weeks of the primary event, by quantitative analysis of 2-dimensional echocardiographic images. Endocardial segmentations of the left ventricular (LV) endocardium...

Background and Objectives: There are different types of vascular access. We compared the patency rate for six months in ulnar-basilic fistula and Radio-Cephalic fistula for vascular access in hemodialysis patients.   Methods: The study was performed on 60 patients of 50.6±13.5 years of age with end-stage renal failure undergoing hemodialysis from 2012-2014 in Imam Ali hospital in Zahedan. Pat...

a 78-year-old woman with burn-induced cervico-mento-sternal scar contracture was scheduled for laparoscopic cholecystectomy. during inhalational induction of sevoflurane, her airway patency deteriorated. the right lateral position and assist ventilation using a breathing bag dramatically improved her airway patency.

OBJECTIVE This study explored the long-term outcomes of arteriovenous fistulas treated with vonapanitase (recombinant human elastase) at the time of surgical creation. METHODS This was a randomized, double-blind, placebo-controlled trial of 151 patients undergoing radiocephalic or brachiocephalic arteriovenous fistula creation who were randomized equally to placebo, vonapanitase 10 μg, or von...

The internal thoracic artery is the most effective conduit for coronary artery bypass surgery; however, most patients have multivessel disease and require additional saphenous vein or radial artery grafts. In this systematic review of the literature and meta-analysis, we aim to compare reported patency rates for these conduits and explore if differences are homogeneous across follow-up interval...

BACKGROUND A patent vascular access is crucial for hemodialysis patients. Stenosis and thrombosis lead to access failure. Endothelial injury via angiotensin II may mediate a hyperplastic and prothrombotic response. Thus angiotensin II inhibition with angiotensin-converting enzyme inhibitors (ACEI) may prolong vascular access patency. This study determines the impact of ACEI use on access patenc...

BACKGROUND/AIM Pancreatitis is the most common and feared complication of endoscopic retrograde cholangiopancreatography (ERCP). We previously examined patency of the accessory pancreatic duct (APD) by dye injection endoscopic retrograde pancreatography (ERP). APD patency was found in 43% of 291 control cases who had no particular changes in the head of the pancreas compared to only 6% in patie...

BACKGROUND Patency of the revascularization conduit is an essential predictor of long-standing survival after coronary artery bypass grafting. OBJECTIVES We have conducted this study to compare the mid-term patency rates of radial artery (RA), left internal thoracic artery (LITA) and also saphenous vein (SV) grafts in asymptomatic patients following coronary artery bypass graft surgery (CABG)...
