Rapid ultrasound score as an indicator of atherosclerosis' clinical manifestations in a population of hypertensives: the interrelationship between flow-mediated dilatation of brachial artery, carotid intima thickness, renal resistive index and retina resistive index of central artery.

Objective: Flow-mediated dilatation (FMD) of brachial artery, renal resistive index (RRI), retina resistive index of central artery (RRICA) and carotid intima-media thickness (IMT) have been used for ultrasound assessment of cardiovascular risk as good surrogate markers of pre-clinical atherosclerosis. We investigated the interrelationship of these four parameters and examined whether an integrated score is a good indicator of atherosclerotic disease in hypertensives.

Methods: One-hundred fifty-two consecutive subjects were enrolled in this study between April 2004 and April 2005.

Which is the correct management of patients with asymptomatic severe calcific aortic stenosis after symptomatic spontaneous calcium cerebral embolism?

Elective surgery cannot be recommended in every patient with asymptomatic severe aortic stenosis, and predictors identifying high-risk patients need to be identified. In guidelines we read that elective surgery, at the asymptomatic stage, can only be recommended in selected patients, at low operative risk (see guidelines of European Society of Cardiology and American Heart Association), but we have not read any reference to patients with severe calcific aortic stenosis after symptomatic spontaneous calcium cerebral embolism. Because cardioembolic stroke is associated with poor prognosis compared to other stroke subtypes, in patients with asymptomatic severe aortic stenosis and spontaneous calcific embolic stroke valve replacement appears to offer the best hope of avoiding a recidivation of stroke and should be considered in most cases.

Clinical outcomes after treatment of non-contained intrabony defects with enamel matrix derivative or guided tissue regeneration: a 12-month randomized controlled clinical trial.

Background: The purpose of this study is to compare the healing of deep, non-contained intrabony defects (i.e., with a ≥80% 1-wall component and a residual 2- to 3-wall component in the most apical part) treated with either an enamel matrix derivative (EMD) or guided tissue regeneration (GTR) after 12 months.
