Sustained exposure to acute migraine medications combined with repeated noxious stimulation dysregulates descending pain modulatory circuits: Relevance to medication overuse headache.

Cephalalgia 2018 Oct 4:333102418804157. Epub 2018 Oct 4.

1 Department of Pharmacology, University of Arizona, Tucson, AZ, USA.

Background Loss of conditioned pain modulation/diffuse noxious inhibitory controls has been demonstrated in patients with migraine and medication overuse headache. We hypothesized that exposure to acute migraine medications may lead to dysregulation of central pain modulatory circuits that could be revealed by evaluating diffuse noxious inhibitory controls and that prior noxious stimulus is required for a loss of the diffuse noxious inhibitory control response in rats exposed to these medications. Methods Rats were "primed" by continuous infusion of morphine or one of two doses of sumatriptan. Read More

Current understanding of trigeminal ganglion structure and function in headache.

Cephalalgia 2018 Jan 1:333102418786261. Epub 2018 Jan 1.

2 Department of Molecular Physiology and Biophysics, University of Iowa, Iowa City, IA, USA.

Introduction The trigeminal ganglion is unique among the somatosensory ganglia regarding its topography, structure, composition and possibly some functional properties of its cellular components. Being mainly responsible for the sensory innervation of the anterior regions of the head, it is a major target for headache research. One intriguing question is if the trigeminal ganglion is merely a transition site for sensory information from the periphery to the central nervous system, or if intracellular modulatory mechanisms and intercellular signaling are capable of controlling sensory information relevant for the pathophysiology of headaches.

Here, we evaluated efficacy and safety of monthly erenumab (70 mg or 140 mg) versus placebo in the subgroup of patients who had previously failed preventive treatment(s) (≥ 1, ≥ 2 prior failed medication categories) and in patients who had never failed. Methods Subgroup analyses evaluated change from baseline in monthly migraine days; achievement of ≥ 50% and ≥ 75% reduction in monthly migraine days; and change in monthly acute migraine-specific medication days.

The association between migraine and hospital readmission due to pain after surgery: A hospital registry study.

Cephalalgia 2018 Jan 1:333102418786457. Epub 2018 Jan 1.

1 Department of Anesthesia, Critical Care, and Pain Medicine, Massachusetts General Hospital and Harvard Medical School, Boston, MA, USA.

Background Migraine has been identified as a risk factor of 30-day hospital readmission after surgery. We aimed to further characterize this association examining pain as a potentially migraine-associated, preventable reason for readmission. Hypothesis Compared to patients with no migraine, surgical patients with migraine are at increased risk of 30-day hospital readmission with an admitting diagnosis specifying pain. Read More

Brain structure and function related to headache: Brainstem structure and function in headache.

Cephalalgia 2018 Jan 1:333102418784698. Epub 2018 Jan 1.

3 Department of Neural and Pain Sciences, University of Maryland Baltimore, Baltimore, MD, USA.

Objective To review and discuss the literature relevant to the role of brainstem structure and function in headache. Background Primary headache disorders, such as migraine and cluster headache, are considered disorders of the brain. As well as head-related pain, these headache disorders are also associated with other neurological symptoms, such as those related to sensory, homeostatic, autonomic, cognitive and affective processing that can all occur before, during or even after headache has ceased.
