AbstractPurpose of reviewCarotid atherosclerotic plaque composition influences plaque rupture risk and may be used to better stratify patients based on ischemic stroke risk than degree of luminal stenosis alone. The goal of this review is to critically evaluate the ability of both conventional and advanced noninvasive vascular imaging techniques to identify and characterize vulnerable carotid plaques.Recent findingsAdvanced noninvasive vascular imaging techniques include contrast-enhanced vascular ultrasound, dual-energy CT, and MR vessel wall imaging (VWI). Each of these modalities has unique strengths with the ability to...

Authors: Baud JM, Stanciu D, Yeung J, Maurizot A, Chabay S, de Malherbe M, Chadenat ML, Bachelet D, Pico F Abstract INTRODUCTION: Carotid atherosclerosis represents 8 to 15% of ischemic strokes in relation to the concept of "vulnerable" plaque. Contrast enhanced ultrasound (CEUS) can detect moving microbubbles within the plaque corresponding to neovessels that constitute "precursors" of vulnerable plaque and intraplaque hemorrhage. CEUS was not studied specifically in acute ischemic strokes. The aim of this study is to analyse the prevalence of CEUS carotid plaque ipsilateral at the ischemic str...

In this study, 5% of VF arrest was due to PE: V fib is initial rhythm in PE in 3 of 60 cases. On the other hand, if the presenting rhythm is PEA, then pulmonary embolism is likely.  When there is VF in PE, it is not the initial rhythm, but occurs after prolonged PEA renders the myocardium ischemic.--Another study by Courtney and Kline found that, of cases of arrest that had autopsy and found that a presenting rhythm of VF/VT had an odds ratio of 0.02 for massive pulmonary embolism as the etiology, vs 41.9 for PEA.    ===================================MY Comment by KEN ...

AbstractMost of the acute ischemic events, such as acute coronary syndromes and stroke, are attributed to vulnerable plaques. These lesions have common histological and pathophysiological features, including inflammatory cell infiltration, neo-angiogenesis, remodelling, haemorrhage predisposition, thin fibrous cap, large lipid core, and micro-calcifications. Early detection of the presence of a plaque prone to rupture could be life-saving for the patient; however, vulnerable plaques usually cause non-haemodynamically significant stenosis, and anatomical imaging techniques often underestimate, or may not even detect, these ...

Discussion The term, cerebral palsy, or CP has gone through many iterations with the first description in 1861 by W.J. Little who described it as “The condition of spastic rigidity of the limbs of newborn children.” The most recent definition is from Rosenbaun et al. in 2007 which states it is “a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. The motor disorders of cerebral palsy are often accompanied by disturbances of sensation, perception, cog...

ConclusionUltrafast ultrasound imaging is an innovative, easily accessible technique that provides imaging modalities on top of the conventional B-mode. Ultrafast ultrasound biomarkers such as plaque stiffness heterogeneity, WSS and intraplaque micro-flows could help to define the vulnerability of the carotid plaque in order to stratify patients that could benefit most from endarterectomy or intensive medical therapy.
