liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...

AIMS The study was designed to assess atrio-ventricular (AV) conduction with non-invasive methods at least 1 year after radiofrequency ablation (RFA) of the slow pathway for AV node reentry tachycardia. METHODS AND RESULTS Medical records of all patients who underwent RFA before their 18th birthday were reviewed. Patients were brought back for clinical evaluation, an electrocardiogram, an exe...

introduction: oral premalignant lesions are conditions having high potential tendency for transformation into malignancy. the use of a conservative and effective treatment modality is one of the best strategies for cancer prevention. photodynamic therapy (pdt) is a non-invasive method for topical and selective treatment of oral precancerous lesions. the present study was taken up to determine t...

OBJECTIVE To compare the efficacy of non-invasive testing for Helicobacter pylori with that of endoscopy (plus H pylori testing) in the management of patients referred for endoscopic investigation of upper gastrointestinal symptoms. DESIGN Randomised controlled trial with follow up at 12 months. SETTING Hospital gastroenterology unit. PARTICIPANTS 708 patients aged under 55 referred for e...

This paper describes a novel approach designed for non-invasive, routine screening of patients cardiovascular disorders without the complexities using an electrocardiogram or invasive probes. Specifically, oscillographic-view brachial artery blood pressure waveform, including dicrotic notch, is extracted from information in pulsations ordinary cuff. The novelty this that total continuous shape ...

background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

Revascularization of the extracranial carotid arteries is a commonly performed surgical procedure to prevent stroke. Open surgery (i.e., carotid endarterectomy [CEA]) is a well-established stroke prevention procedure but is being 'challenged' by a less invasive percutaneous procedure (i.e., carotid artery stent [CAS] placement). Clinical trials comparing CAS and CEA for average-surgical-risk pa...
