Late outcomes after carotid artery stenting versus carotid endarterectomy: insights from a propensity-matched analysis of the Reduction of Atherothrombosis for Continued Health (REACH) Registry.

Background: In patients with carotid artery disease, carotid endarterectomy (CEA) and carotid stenting (CAS) are treatment options. Controversy exists as to the relative efficacy of the 2 techniques in preventing late events.

Methods And Results: The Reduction of Atherothrombosis for Continued Health (REACH) Registry recruited > 68,000 outpatients ≥ 45 years of age with established atherothrombotic disease or ≥ 3 risk factors for atherothrombosis.

High prevalence of peripheral arterial disease in patients with acute ischaemic stroke.

Background: After acute ischaemic stroke (AIS) or transient ischaemic attack (TIA), the detection of peripheral arterial disease (PAD) as a marker of generalized atherosclerosis may improve the risk stratification and prevention of future atherothrombotic events. We aimed to determine the prevalence of PAD indicated by an ankle-brachial index (ABI) of < or =0.9 in a large cohort of patients with AIS/TIA.

Beneficial effect of rituximab monotherapy in multifocal motor neuropathy.

Multifocal motor neuropathy (MMN) is a chronic, pure motor, asymmetric neuropathy for which intravenous immunoglobulin (IVIg) is widely regarded as first-line treatment. Rituximab is a monoclonal antibody against CD20+ cells that causes prolonged B cell depletion, a well-tolerated therapy currently explored in several immune-mediated neurologic disorders. We report three patients with MMN, who had become increasingly less responsive to IVIg but showed sustained clinical improvement following rituximab monotherapy.

Rituximab for myasthenia gravis: three case reports and review of the literature.

In generalized myasthenia gravis (MG), a wide array of immunosuppressive and immunomodulating treatments is being used in clinical practice, but most drugs lack evidence from randomized controlled trials supporting their use. Furthermore, many patients develop serious side effects or do not respond sufficiently to these drugs. We report three patients with generalized MG who were treated with rituximab, a monoclonal antibody against CD20+ cells that causes prolonged B cell depletion.

Quantitative autonomic testing in the management of botulism.

Even with mild neurological signs, patients with botulism frequently complain of autonomic symptoms. This study aimed at the evaluation of sudomotor and cardiovascular reflex functions by quantitative autonomic testing (QAT), which may identify patients with autonomic involvement but otherwise benign clinical presentation. Five patients with food-borne botulism were subjected to a structured questionnaire on autonomic symptoms, cardiac and neurological examination, and QAT after a median of 2 weeks (baseline) and 12 weeks (follow-up) post intoxication.

Cerebral vasculitis and stroke in Lyme neuroborreliosis. Two case reports and review of current knowledge.

We report on 2 patients with cerebral vasculitis and stroke due to Lyme neuroborreliosis (LNB). Both patients had a prodromal stage involving headaches, and showed meningeal enhancement in addition to ischemic infarctions on brain magnetic resonance imaging and diffuse vasculitis on vascular imaging. Serological and cerebrospinal (CSF) fluid studies confirmed the diagnosis of active LNB.

[Baseline predictors of outcome in stroke patients treated with intravenous thrombolysis--the Austrian stroke unit registry].

Background: Intravenous thrombolysis (IVT) for acute ischaemic stroke is safe and effective in routine clinical use. We aimed to identify baseline predictors of excellent outcome after 3 months, defined by a modified Rankin Scale score
Method: We analysed data entered in the Austrian Stroke Unit Registry up to February 28th 2007.

Prognostic value of admission C-reactive protein in stroke patients undergoing iv thrombolysis.

Objective: To test the hypothesis that pre-treatment Creactive protein (CRP) predicts outcome in stroke patients undergoing intravenous thrombolysis (IVT) treatment.

Methods: We analyzed the data of 111 consecutive patients with IVT within 6 hours of stroke onset for stroke involving the middle cerebral artery territory and admission CRP < or = 6 mg/dl.

Results: CRP levels were consistently, yet non-significantly lower in patients with unfavourable outcome definitions.

Risk factor profile and management of cerebrovascular patients in the REACH Registry.

Background: Cerebrovascular disease (CVD) is a global public health problem. CVD patients are at high risk of recurrent stroke and other atherothrombotic events. Prevalence of risk factors, comorbidities, utilization of secondary prevention therapies and adherence to guidelines all influence the recurrent event rate.

Multitracer study in Heidenhain variant of Creutzfeldt-Jakob disease: mismatch pattern of cerebral hypometabolism and perfusion imaging.

Creutzfeldt-Jakob disease (CJD) is a subacute spongiform encephalopathy. This fatal prion disease is characterized by rapidly progressive dementia with a variety of neurological disorders. Diagnostic methods provided by nuclear medicine might be helpful for evaluation of patients with probable CJD as additional diagnostic tools to MRI and cerebro-spinal fluid evaluation.

Thrombolysis beyond the guidelines: two treatments in one subject within 90 hours based on a modified magnetic resonance imaging brain clock concept.

Background And Purpose: We report the first case of 2 intravenous thrombolysis treatments within 90 hours in a patient with early recurrent stroke.

Summary Of Review: A 50-year-old man had improved significantly after intravenous thrombolysis for acute stroke. On the fourth day, he deteriorated dramatically because of recurrent stroke.

Importance of T2*-weighted gradient-echo MRI for diagnosis of cortical vein thrombosis.

We examined six patients with isolated venous thrombosis (n = 2), or venous thrombosis combined with sinus thrombosis (n = 4) (CVT). The clinical symptoms were non-specific (acute cephalea, paresis, epileptic seizure, progressive speech disorder). All examinations were performed on a 1.

Serial contrast-enhanced magnetic resonance imaging and spectroscopic imaging of acute multiple sclerosis lesions under high-dose methylprednisolone therapy.

To evaluate biochemical changes in contrast-enhancing multiple sclerosis (MS) lesions, we examined 14 patients with relapsing-remitting MS at acute clinical exacerbation with the help of contrast-enhanced magnetic resonance imaging (MRI) and 1H magnetic resonance spectroscopic imaging (1H MRSI). Using a 1.5-tesla MR system (Magnetom Vision, Siemens, Germany), we followed 29 contrast-enhancing and 24 nonenhancing MS lesions as well as normal-appearing white matter (NAWM) before and during high-dose methylprednisolone (HDMP) therapy.

[Diagnosis of stroke--an update].

In practical day-to-day terms, most patients have one of the common causes of stroke: ischemic stroke caused by the complications of atherothrombosis, intracranial small Vessel disease, embolism from the heart, primary intracerebral hemorrhage caused by hypertension, or subarachnoid hemorrhage as a result of a ruptured saccular aneurysm. There are three issues to be considered in assessing the reliability of the clinical diagnosis of stroke: the diagnosis of stroke itself: is it a stroke or not; whether the stroke is caused by an infarct or a hemorrhage and particular in ischemic stroke the site and size of the lesion (anterior vs. posterior circulation, lacunar vs.
