2013 | P. Zamboni, E. Menegatti, S. Occhionorelli, F. Salvi | The controversy on chronic cerebrospinal venous insufficiency | The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI) and its association with both neurodegenerative disorders and multiple sclerosis (MS). We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. | Full Content, sintesi commentata |
2013 | C. Leone, E. D’Amico, S. Cilia, A. Nicoletti, L. Di Pino, F. Patti | Cognitive impairment and “invisible symptoms” are not associated with CCSVI in MS | We investigated the association between chronic cerebrospinal venous insufficiency (CCSVI) and cognitive impairment (CI) in multiple sclerosis (MS).

2013 | M. J. Joyner1, D. P. Casey | Muscle Blood Flow, Hypoxia and Hypoperfusion | Blood flow increases to exercising skeletal muscle and this increase is driven primarily by vasodilation in the contracting muscles. When oxygen delivery to the contracting muscles is altered by changes in arterial oxygen content, the magnitude of the vasodilator response to exercise changes. It is augmented during hypoxia and blunted during hyperoxia. | Abstract, sintesi commentata |
