BACKGROUND The techniques used for the implantation of totally implantable venous access devices (TIVADs) are the percutaneous approach and surgical cutdown; however, the choice is still controversial. HYPOTHESIS The surgical cutdown approach may be beneficial to reduce the rate of complications. DESIGN Retrospective review. SETTING A university hospital and a tertiary referral center. ...
The high morbidity and mortality of patients with esophageal (E) and gastro-esophageal junction (GEJ) cancers, warrants new pre-clinical models for drug testing. The utility of primary tumor xenografts (PTXGs) as pre-clinical models was assessed. Clinicopathological, immunohistochemical markers (p53, p16, Ki-67, Her-2/neu and EGFR), and global mRNA abundance profiles were evaluated to determine...
PURPOSE To compare the implant quality and clinical outcomes for patients treated with low and intermediate strength (125)I seeds in prostate brachytherapy implants. METHODS AND MATERIALS This retrospective review included 390 consecutive patients treated with prostate brachytherapy from 1999 to 2006. The first 142 patients were implanted with source strengths lower than 0.415U (0.327mCi), wi...
A 65-year-old man was referred with refractory heart failure. A 27-mm Carbomedics bileaflet valve for mitral valve stenosis had been implanted 20 years earlier. The electrocardiogram showed atrial fibrillation with severe bradycardia (30-50/min). Transthoracic echocardiography demonstrated both prosthetic leaflets opening in late diastole (Picture A, arrows), and the anterolateral leaflet inter...
Local cerebral blood flow (1CBF) was measured simultaneously in ten cats with (1) a large surface thermal diffusion probe resting on the cortex and (2) hydrogen clearance curves from implanted electrodes surrounding the thermal probe. A close correlation was found between 1CBF values obtained by the two methods. Since hydrogen clearance is accepted as quantitative, the data suggest that the the...
Although early occlusion of saphenous vein coronary artery bypass grafts is usually thrombotic, late occlusion is most often a result of progressive intimal fibromuscular proliferation or atheroma formation in the implanted vain. We describe another mechanism of late graft occlusion: atheromatous plaque rupture with superimposed occlusive thrombosis. Four men, ages 48-67 years underwent repeat ...
Introduction: Speech intelligibility, the ability to be understood verbally by listeners, is the gold standard for assessing the effectiveness of cochlear implantation. Thus, the goal of this study was to compare the speech intelligibility between normal-hearing and cochlear-implanted children using the Persian intelligibility test. Materials and Methods: Twenty-six cochlear-implanted childre...
OBJECTIVES The purpose of this study was to evaluate the frequency and predictors of stent thrombosis (ST) after stenting for ST-segment elevation myocardial infarction (STEMI). BACKGROUND Stent thrombosis remains a major concern with STEMI patients treated with primary percutaneous coronary intervention. METHODS Consecutive patients (N = 1,640) undergoing stenting for STEMI were prospectiv...
OBJECTIVE Ventricular assist devices (VADs) have been implanted since 1990 in our institution, becoming an increasingly common treatment for end-stage heart failure. Beginning in 1997, VAD patients were discharged home when feasible. In August 2003, a dedicated multidisciplinary VAD team (cardiac surgeons, cardiologists, VAD coordinators, nurses, rehabilitation specialists, nutrition experts, p...
