Congenital Spinal Malformation and Stroke: Aneurysmal Dilatations and Bilateral Rotational Vertebral Artery Occlusion.

A 30-year-old woman suffered from acute vertebrobasilar stroke. Cranial tomography (CT) scans showed multiple vertebral abnormalities suggestive of congenital spine malformation, and angiographic CT revealed aneurysmal dilatations (ADs) at segment V2 of both vertebral arteries (VAs). Dynamic neuroimaging tests including angiography and angio-CT were performed and showed occlusion of both VAs at the point of the ADs with contralateral rotation of the neck.

Epigenetic Changes in the Methylation Patterns of KCNQ1 and WT1 after a Weight Loss Intervention Program in Obese Stroke Patients.

Ischemic stroke patients often show high concentrations of circulating inflammatory markers that are associated with increased risk of recurrence. Epigenetic mechanisms could be involved in obesity, inflammation and stroke. The objective of this research was to investigate, in obese patients suffering a previous stroke, the effects of a nutritional program on anthropometric and biochemical variables, and on the methylation patterns of two stroke-related genes (KCNQ1: potassium channel, voltage gated KQT-like subfamily Q, member 1; and WT1: Wilms tumor 1).
