Mild mechanical traumas are possible risk factors for cervical artery dissection.
Cervical artery dissection (CAD) is a common cause of ischemic stroke in younger aged subjects. Retrospective studies suggest cervical manipulative therapy (CMT) and preceding infections as extrinsic risk factors for CAD. In a case-control study, we assessed a questionnaire with 7 mild mechanical traumas as potential trigger factors for CAD, including CMT and recent infections. ⋯ Mild mechanical stress, including CMT, plays a role as possible trigger factor in the pathogenesis of CAD. CMT and recent infections alone failed to reach significance during the present investigation, presumably due to the relatively small sample size of the study cohort.

Though the proportion of elderly stroke patients is increasing, patients >80 years are often excluded from clinical stroke trials. We reviewed the management of older patients presenting with acute ischemic stroke (AIS) and assessed the safety and efficacy of recombinant tissue plasminogen activator (rtPA) administration in a community-based setting. ⋯ Early treatment with rtPA in patients >80 years appears to be both safe and efficacious. Treated patients showed improvements both acutely (a decrease in NIHSS at 72 h) and chronically, as shown by a sustained improvement in the Barthel Index. A large number of elderly patients were excluded from rtPA treatment despite arriving within the time frame of treatment for reasons not considered as traditional exclusion criteria. Older patients with AIS can be treated safely with thrombolytic therapy in a community setting. This therapy should not be withheld on the basis of age.

The number of persons reaching the age 80 years and over is increasing in most populations. Literature focusing on hypertensive intracerebral hemorrhage (ICH) in this age group is lacking. Therefore, we aimed to analyze the main clinical characteristics of ICH of the advanced old age, in the context of hypertension. ⋯ ICH occurring in hypertensive patients aged > or =80 years has several differences from that seen in younger people; however, these differences do not seem to impact on early outcome.

Randomized Controlled Trial Multicenter StudyRationale, design and baseline data of a randomized, double-blind, controlled trial comparing two antithrombotic regimens (a fixed-dose combination of extended-release dipyridamole plus ASA with clopidogrel) and telmisartan versus placebo in patients with strokes: the Prevention Regimen for Effectively Avoiding Second Strokes Trial (PRoFESS).
Individuals with transient ischemic attack and ischemic stroke have a high risk of recurrent stroke and death. While acetylsalicylic acid (ASA, aspirin) is proven and accepted as standard therapy in these patients, recent trials demonstrate that a combination of ASA and dipyridamole (DP) or clopidogrel may be superior to ASA. Blocking the renin-angiotensin system with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers may also reduce recurrent stroke. The ongoing PRoFESS (Prevention Regimen for Effectively Avoiding Second Strokes) trial is designed to evaluate whether ASA + extended-release DP compared to clopidogrel, and whether telmisartan in addition to usual care in individuals after a stroke, will reduce the risk of further strokes. ⋯ PRoFESS is the largest secondary stroke prevention trial to date and will directly compare two antiplatelet regimens as well as the benefit of telmisartan versus placebo.
