Randomized Controlled Trial Clinical Trial
A double-blind, dose comparison study of topiramate for prophylaxis of basilar-type migraine in children: a pilot study.
Basilar-type migraine (BM) is the most common migraine "variant," representing 3-19% of migraine in children.BMis characterized by attacks of dizziness, vertigo, visual disturbances, ataxia, and/or diplopia, followed by migraine headache. ⋯ Preventive therapy with topiramate resulted in reducing the overall migraine frequency and the frequency of attacks of BM at both 25 mg and 100 mg doses relative to the historical baseline and prospective baseline periods. The 2 treatment groups resulted in comparable outcomes.

Randomized Controlled Trial Multicenter Study Clinical Trial
The impact of topiramate on health-related quality of life indicators in chronic migraine.
Chronic migraine is a disabling primary chronic daily headache disorder that significantly impacts the daily activities of patients with this disorder. To our knowledge, this is the first report of a large, randomized, double-blind, placebo-controlled trial that assessed the impact of topiramate on the daily activities, emotional distress, headache-related disability, and global impression of change in patients with chronic migraine. ⋯ Compared with placebo-treated patients, topiramate 100 mg/day appears to contribute to reductions in migraine-related limitations on daily activities and emotional distress beginning as early as week 4 and continuing up to week 16 after treatment. Physician's Global Impression of Change results are very similar with Subject's Global Impression of Change, indicating concordance between the physician's and the subject's assessment of improvement.

Carotid artery dissection has been reported to occur spontaneously and after many types of neck trauma. A case patient is presented who developed a right-sided oculosympathetic palsy and was found to have bilateral carotid artery dissection after she visited her dentist. To the best of our knowledge, this case represents the first report of bilateral carotid dissection following dental work.

The goal of this study was to determine whether the physiological effects of carbon dioxide (CO(2)) involve regulation of CGRP secretion from trigeminal sensory neurons. ⋯ Results from this study provide the first evidence of a unique regulatory mechanism by which CO(2) inhibits sensory nerve activation, and subsequent neuropeptide release. Furthermore, the observed inhibitory effect of CO(2) on CGRP secretion likely involves modulation of calcium channel activity and changes in intracellular pH.
