BACKGROUND To characterize the cells responsible for neointima formation after porcine coronary artery wall injury, we studied the expression of smooth muscle cell (SMC) differentiation markers in 2 models: (1) self-expanding stent implantation resulting in no or little interruption of internal elastic lamina and (2) percutaneous transluminal coronary(More)
BACKGROUND Optical coherence tomography has emerged as a new tool for quantifying axonal loss in multiple sclerosis (MS). A reduction in retinal nerve fiber layer (RNFL) thickness is correlated with Expanded Disability Status Scale score and brain atrophy. OBJECTIVE To investigate RNFL and macular volume measurements using optical coherence tomography in(More)
BACKGROUND This prospective, multicenter study sought to evaluate the incidence of asymptomatic cerebral emboli (ACE) during ablation of atrial fibrillation (AF) using a multielectrode radiofrequency (MER) system when specific procedural changes were applied. METHODS AND RESULTS Sixty subjects (age 60±10 years; 87% paroxysmal; CHADS2 score, 0.6±0.7)(More)
BACKGROUND Atrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all-cause mortality may guide interventions. METHODS AND RESULTS In the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial(More)
Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is characterized by the presence of myelinated retinal fibers. This typical feature is very helpful for the diagnosis but is not always observed in patients outside Quebec. Apart from phenotype variations, misinterpretation of the funduscopy may explain discrepancies and misdiagnosis. We(More)
To evaluate quantification of metamorphopsia before and after the removal of unilateral epiretinal membrane (ERM). One hundred and four consecutive patients with unilateral ERM scheduled for membrane peeling were prospectively enrolled. A complete ophthalmologic examination was performed. Metamorphopsia was evaluated, with standard Amsler grids and a laser(More)
Syncope is frequently neurally mediated and can seriously affect quality of life. Different ablation strategies have been successfully performed. These approaches have not gained wide acceptance and are quite extensive and complex, exposing patients to significant risks. This article reports the case of a 16-year-old girl who was severely affected by(More)
Headache patients and healthy controls underwent alpha-EEG feedback training in 12 sessions. The present study does not support the literature which reports alpha increase by feedback training. The study included a patient group receiving feedback, a patient control group receiving pseudofeedback, and a volunteer group receiving feedback. Increase of alpha(More)
