Associations from sensitivity analyze that segregated women according to probable migraine (ICHD-2 category 1.6.1) and migraine (ICHD-2 category 1.1) diagnoses were of similar magnitudes as those reported here for women with any migraine diagnoses. IPV, particularly sexual violence, appears to be a risk factor for migraine. Conclusion.— Our findings suggest the potential R788 research buy importance of considering a history of violence among migraineurs. “
“To determine if baseline/interictal saliva calcitonin gene-related peptide (CGRP) levels would be lower in subjects with

chronic migraine receiving onabotulinumtoxinA compared with those receiving saline. CGRP is considered central to the pathogenesis of episodic migraine, but its relationship to chronic migraine is less understood. OnabotulinumtoxinA is an effective treatment for chronic migraine and has been demonstrated to inhibit the vesicular release of CGRP. This was an exploratory, randomized, placebo-controlled, crossover pilot study of 20 subjects that received onabotulinumtoxinA and saline injection (placebo). The amount of CGRP in saliva samples collected on a nonheadache or low headache day, and prior to JAK inhibitor and after treatment of a headache exacerbation was measured. Daily headache records, medications, and response to treatment were recorded

in a diary. A decrease in baseline/interictal saliva CGRP levels for subjects receiving onabotulinumtoxinA Carbohydrate from 39.4 ± 7.5 pg CGRP/mg total protein after the first month to 25.5 ± 4.1 pg after the third month was observed. However, this difference did not reach significance nor was it significant when compared to the saline treatment. There was a reduction in the number of headache days for both onabotulinumtoxinA and saline over baseline throughout the active phases of the study. However, there was no statistical difference in headache days between groups. Subjects with a greater than 50% response to onabotulinumtoxinA had better 2-hour pain relief with acute treatment than non-responders to onabotulinumtoxinA

or saline. While CGRP levels were not elevated during a migraine attack in chronic migraine subjects as has been reported in episodic migraine, there was an overall decrease in the baseline/interictal levels in response to onabotulinumtoxinA. “
“(Headache 2010;50:965-972) Objective.— To evaluate relative telomere length of female migraine patients. Background.— Migraine is a debilitating disorder affecting 6-28% of the population. Studies on the mechanisms of migraine have demonstrated genetic causes but the pathophysiology and subcellular effects of the disease remain poorly understood. Shortened telomere length is associated with age-related or chronic diseases, and induced stresses. Migraine attacks may impart significant stress on cellular function, thus this study investigates a correlation between shortening of telomeres and migraine. Methods.
