Multicenter Study Comparative Study
Migraine in cervical artery dissection and ischemic stroke patients.
Several small to medium-sized studies indicated a link between cervical artery dissection (CeAD) and migraine. Migrainous CeAD patients were suggested to have different clinical characteristics compared to nonmigraine CeAD patients. We tested these hypotheses in the large Cervical Artery Dissection and Ischemic Stroke Patients (CADISP) population. ⋯ Migraine without aura is more common among CeAD(stroke) patients compared to non-CeAD IS patients. The mechanisms and possible causative link remain to be proved. Although CeAD is often complicated by stroke, our data do not support increased risk of stroke in migrainous CeAD patients.

Randomized Controlled Trial Multicenter Study Comparative Study
Alemtuzumab more effective than interferon β-1a at 5-year follow-up of CAMMS223 clinical trial.
To report the long-term safety and efficacy results from CAMMS223 comparing alemtuzumab with interferon β-1a in early, active relapsing-remitting multiple sclerosis (RRMS). What are the long-term effects of alemtuzumab treatment, received 36 to 48 months previously, on relapse and disability in early, active RRMS? This study provides evidence of the effectiveness of alemtuzumab in reducing the relapse rate and accumulation of disability compared with interferon β-1a (IFNβ-1a) through extended follow-up (up to 60 months from baseline). ⋯ This study provides Class III evidence that alemtuzumab is more effective than interferon β-1a in reducing relapses and disability in patients with RRMS in a long-term follow-up of a rater-blinded, randomized clinical trial with 59.5% of patients participating in the extended follow-up period.
