We describe the frequency, duration, clinical characteristics, and radiologic correlates of central poststroke pain (CPSP) in young ischemic stroke survivors in a prospective study setting. ⋯ Late persistent CPSP was found in 5.9% of young stroke survivors and was associated with concomitant other pain, impaired quality of life, and moderate or severe stroke symptoms.

To determine the risk of osteoporosis in patients with myasthenia gravis (MG) in a large cohort representing 99% of the population of Taiwan. ⋯ This population-based retrospective cohort study provides evidence that MG is associated with a high risk of osteoporosis regardless of corticosteroid use.

We investigated a large sample of patients with amyotrophic lateral sclerosis (ALS) at rest in order to assess the value of (18)F-2-fluoro-2-deoxy-d-glucose ((18)F-FDG) PET as a biomarker to discriminate patients from controls. ⋯ This study provides Class III evidence that (18)F-FDG-PET accurately distinguishes patients with ALS from normal controls (sensitivity 95.4%, specificity 82.5%).

Randomized Controlled Trial Multicenter Study
Randomized controlled trial of the CGRP receptor antagonist telcagepant for migraine prevention.
To evaluate whether the calcitonin gene-related peptide (CGRP) receptor antagonist telcagepant might be effective for migraine prevention. ⋯ This study provides Class II evidence that in patients with migraine, telcagepant taken daily reduces headache days by 1.4 days per month compared to placebo and causes 2.5% of patients to have elevations of serum ALT levels.
