Controlled Clinical Trial
Comparison of elective stenting of severe vs moderate intracranial atherosclerotic stenosis.
To test whether symptomatic severe intracranial atherosclerotic stenosis was associated with a higher subsequent stroke risk than moderate stenosis after elective angioplasty with a balloon-expandable stent and to explore which factors were associated with the subsequent stroke. ⋯ Symptomatic severe intracranial atherosclerotic stenosis did not present a higher subsequent stroke risk than moderate stenosis after elective angioplasty with a balloon-expandable stent. Patients with severe stenosis may benefit from successful stent placement, and randomized trials are necessary to demonstrate this possible benefit.

Clinical Trial
Long-term outcome of bilateral pallidal deep brain stimulation for primary cervical dystonia.
Ten patients with severe cervical dystonia (CD) unresponsive to medical treatment underwent bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) and were followed for 31.9 +/- 20.9 months. At last follow-up, the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) severity score improved by 54.8%, the TWSTRS disability score improved by 59.1%, and the TWSTRS pain score improved by 50.4%. Bilateral GPi DBS is an effective long-term therapy in patients with CD.

To define temporal trends in the incidence of anticoagulant-associated intracerebral hemorrhage (AAICH) during the 1990s and relate them to rates of cardioembolic ischemic stroke. ⋯ The incidence of anticoagulant-associated intracerebral hemorrhage quintupled in our population during the 1990s. The majority of this change can be explained by increasing warfarin use. Anticoagulant-associated intracerebral hemorrhage now occurs at a frequency comparable to subarachnoid hemorrhage.
