BACKGROUND Initially based on histology, the diagnosis of renal artery fibromuscular dysplasia (FMD) is now based mostly on angiographic appearance because arterial tissue samples are rarely available. This retrospective cross-sectional study aimed to assess the clinical relevance of a binary angiographic classification of FMD lesions (unifocal or(More)
A higher risk of cardiovascular events has been reported in patients with primary aldosteronism (PA) than in otherwise similar patients with essential hypertension (EH). However, the evidence is limited by small sample size and potential confounding factors. We, therefore, compared the prevalence of cardiovascular events in 459 patients with PA diagnosed in(More)
The pathogenesis of fibromuscular dysplasia (FMD) remains unclear, but tobacco use is thought to be involved. This retrospective cross-sectional study aimed to evaluate smoking first as a risk factor for renal artery FMD diagnosis and second as a modifier of the clinical and radiological phenotype of this disease. We retrieved 337 adult patients diagnosed(More)
To classify the renal artery (RA) anatomy based on specific requirements for endovascular renal artery denervation (RDN) in patients with drug-resistant hypertension (RH). The RA anatomy of 122 consecutive RH patients was evaluated by computed tomography angiography and classified as two types: A (main RA ≥20 mm in length and ≥4.0 mm in diameter) or B (main(More)

Linezolid is a recent addition to the antibiotic armamentarium against Gram-positive bacteria, including multiresistant staphylococci and enterococci. Linezolid is relatively well tolerated and is not believed to be nephrotoxic. However, we report the case of an 88-year-old woman who was treated for prosthetic joint infection and methicillin-resistant(More)
OBJECTIVES Renal artery fibromuscular dysplasia (FMD) is a heterogeneous condition with a broad and evolving phenotypic and angiographic spectrum. We documented therapeutic management in patients with renal artery FMD, by analyzing the medical records of hypertensive patients diagnosed with FMD at a single referral center from 1986 to 2012. METHODS(More)
BACKGROUND Impaired nitric oxide (NO) release in chronic renal failure has been implicated in the pathogenesis of hypertension and the progression of renal insufficiency. We investigated whether gene delivery of the endothelial NO synthase (eNOS) improves NO release and reduces blood pressure and renal failure and injury in rats with reduced renal mass. (More)
We explore in this qualitative research the challenges faced by bilingual health and social services professionals in a Canadian bilingual setting, as well as the strategies used to overcome them. Eight focus groups were conducted with a total of 43 bilingual Francophone professionals who offered services in French in 21 health and social service(More)
OBJECTIVE Hy-Result is the first software for self-interpretation of home blood pressure measurement results, taking into account both the recommended thresholds for normal values and patient characteristics. We compare the software-generated classification with the physician's evaluation. DESIGN METHOD The primary assessment criterion was whether(More)
