Review Meta Analysis
Efficacy of Noninvasive Brain Stimulation on Pain Control in Migraine Patients: A Systematic Review and Meta-Analysis.
To evaluate the efficacy of noninvasive brain stimulation (NIBS) on pain control in migraine patients. ⋯ Low or very low quality of evidence suggests that our primary outcome evaluation failed to find support for the superiority of NIBS over sham treatment. Although, subgroup analysis reveals that tDCS have moderate to high effects and could be a promising nonpharmacological alternative to pain control, mainly for painkiller intake reduction. However, there is a need for larger controlled trials with methodological rigor, which could increase the power of result inference.

To evaluate if injection of intravenous particles may provoke migraines in subjects with right-to-left shunts due to pulmonary arteriovenous malformations (AVMs). ⋯ HHT subjects frequently report migraine exacerbation following blood tests, contrast echocardiograms, MRI imaging, and CT studies performed with intravenous contrast medium. Since air emboli are recognized to complicate intravenous injections, particularly those given by a pressurized pump during contrast enhanced CT, future studies should re-evaluate whether particulate emboli provoke migraines.

Olfaction-related symptoms accompany migraine attacks and some, such as osmophobia, may be useful in differentiating migraine from other types of headaches. However, the types and frequencies of olfactory symptoms associated with migraine have not been well characterized. The goal of this study was to better characterize the olfactory symptoms of migraine. ⋯ Odor-related disturbances were common symptoms of the 113 migraineurs, with nearly all reporting osmophobia. Perfume odor was the most common trigger for the migraine. The reported symptoms did not differ between patients with and without auras. Patients who experienced IOH appeared to fundamentally differ from those who did not experience IOH in terms of the incidence of osmophobia and odor-triggered crisis. Subjects who reported experiencing osmophobia and odor-triggered headache reported having worse olfactory acuity.

Pain freedom at 2 hours and sustained pain response at 24 hours are important outcomes of acute migraine therapy. Some studies have examined rates and predictors of successful treatment outcomes for single attacks in clinical trials. However, little is known about predictors of typical response to acute treatment over multiple attacks in the population. ⋯ These results provide a snapshot of the effectiveness of usual acute treatment as well as predictors of inadequate acute treatment response in a large population sample of people with episodic migraine. These results highlight the high rates of unmet treatment needs in people with migraine. Similarities and differences in predictors vary with outcome for reasons that are discussed.

To describe current patterns of use of nerve blocks and trigger point injections for treatment of pediatric headache. ⋯ Despite limited evidence, nerve blocks are commonly used by pediatric headache specialists. There is considerable variability among clinicians as to injection site(s) and medication selection, indicating a substantial gap in the literature to guide practice, and supporting the need for further research in this area.
