Multicenter Study
Prospective study of symptomatic atherothrombotic intracranial stenoses: the GESICA study.
Symptomatic intracranial atherothrombotic stenoses (ICAS) are associated with high rates of cerebrovascular ischemic events. ⋯ Despite medical treatment, the 2-year recurrence rate of ischemic events in the territory of the stenotic artery was 38.2%. Cardiovascular events occurred in 18.6% of patients. Clinically significant hemodynamic stenoses were associated with stroke recurrence and may help identify a high risk subset of patients.

National cholesterol guidelines have defined high vascular risk individuals as those who could potentially benefit most from statin therapy. The authors aimed to determine the rate of statin use, its predictors, and the achievement of national guideline target lipid goals among ischemic stroke survivors. ⋯ Approximately one out of three guideline-eligible high vascular risk ischemic stroke patients in this study had low-density lipoprotein cholesterol concentrations above qualifying levels for pharmacologic therapy, but half of these patients were not taking a statin, and of those receiving statin treatment, less than half were within recommended lipid goals.

Both estrogen and progesterone influence seizure activity in women with epilepsy, with estrogen generally demonstrating proconvulsant and progesterone anticonvulsant effects. Women with epilepsy exhibit a variety of endocrine disturbances, probably due to a combination of factors, including the epilepsy syndrome and the effect of interictal and ictal epileptic discharges in the brain. The direct effects of some antiepileptic drugs (AEDs) further increase this risk, apparently related to a specific drug's effect on hepatic microsomal enzymes of the cytochrome P-450 system. ⋯ Special considerations in women of childbearing age include decreased compliance and disease prevention. Although adequate seizure control is the critical requirement of an AED, the potential for interactions with hormonal contraception and the increased risk for endocrine disturbances caused by drugs that alter hepatic microsomal enzymes suggest additional potential advantages for AED treatment that does not affect these enzymes. Both the constellation of physicians treating women with epilepsy and the patients themselves have a poor understanding of the spectrum of reproductive health issues involved, and increased awareness is needed to improve patient management.

Randomized Controlled Trial Multicenter Study Comparative Study
A Phase II study of the safety and efficacy of teriflunomide in multiple sclerosis with relapses.
Teriflunomide, a dihydro-orotate dehydrogenase inhibitor, has immunomodulatory effects, including the ability to suppress experimental allergic encephalomyelitis. In this randomized, double-blind, placebo-controlled Phase II study, the authors examined the safety and efficacy of oral teriflunomide in multiple sclerosis (MS) with relapses. ⋯ Oral teriflunomide was effective in reducing MRI lesions and was well tolerated in patients with relapsing multiple sclerosis.
