BACKGROUND: Studies suggest that women may be at greater risk for developing chronic pain and pain-related disability. METHODS: Because musculoskeletal disorders (MSD) are the most frequently endorsed painful conditions among veterans, we sought to characterize gender differences in sociodemographic and clinical correlates among veterans upon entry into Veterans Health Administration's Musculoskeletal Disorders Cohort (n = 4,128,008). RESULTS: Women were more likely to be younger, Black, unmarried, and veterans of recent conflicts...

BACKGROUND: Despite their huge epidemiological impact, primary headaches, trigeminal neuralgia and other chronic pain conditions still receive suboptimal medical approach, even in developed countries. The limited efficacy of current pain-killers and prophylactic treatments stands among the main reasons for this phenomenon. Botulinum neurotoxin (BoNT) represents a well-established and licensed treatment for chronic migraine, but also an emerging treatment for other types of primary headache, trigeminal neuralgia, neuropathic pain, and an increasing number of pain conditions...

Although it is well known that migraine pain is enhanced by photic stimulation of the eye, the mechanisms underlying this response are not yet understood. Noxious stimulation to the dura is known to activate trigeminal spinal subnucleus caudalis and upper cervical spinal cord (Vc/C1) neurons, causing migraine pain. Intense photic stimulation to the eye is also known to activate certain Vc/C1 neurons, thus increasing migraine pain. In this study, we hypothesized that Vc/C1 neurons receiving noxious dural input would be further activated by intense photic stimulation, resulting in the enhancement of migraine pain...

Facial allodynia is a migraine symptom that is generally considered to represent a pivotal point in migraine progression. Treatment before development of facial allodynia tends to be more successful than treatment afterwards. As such, understanding the underlying mechanisms of facial allodynia may lead to a better understanding of the mechanisms underlying migraine. Migraine facial allodynia is modeled by applying inflammatory soup (histamine, bradykinin, serotonin, prostaglandin E2) over the dura. Whether glial and/or immune activation contributes to such pain is unknown...

BACKGROUND: Calcitonin gene-related peptide (CGRP) is widely distributed in nociceptive pathways in human peripheral and central nervous system and its receptors are also expressed in pain pathways. CGRP is involved in migraine pathophysiology but its role in non-headache pain has not been clarified. METHODS: We performed a systematic literature search on PubMed, Embase and ClinicalTrials.gov for articles on CGRP and non-headache pain covering human studies including experimental studies and randomized clinical trials...

Calcitonin gene-related peptide (CGRP) is a 37-amino acid peptide found primarily in the C and Aδ sensory fibers arising from the dorsal root and trigeminal ganglia, as well as the central nervous system. Calcitonin gene-related peptide was found to play important roles in cardiovascular, digestive, and sensory functions. Although the vasodilatory properties of CGRP are well documented, its somatosensory function regarding modulation of neuronal sensitization and of enhanced pain has received considerable attention recently...

BACKGROUND: Pain acceptance involves willingness to experience pain and engaging in valued activities while pain is present. Though pain acceptance could limit both headache-related disability and pain interference in individuals with migraine, few studies have addressed this issue. This study evaluated whether higher levels of total pain acceptance and its two subcomponents, pain willingness and activity engagement, were associated with lower levels of headache-related impairment in women who had both migraine and overweight/obesity...

Migraine headaches are a debilitating disease that causes significant socioeconomic problems. One of the speculated etiologies of the generation of migraines is peripheral nerve irritation at different trigger points. The use of Onabotulinum toxin A (BOTOX), although initially a novel approach, has now been determined to be a valid treatment for chronic headaches and migraines as described in the Phase III Research Evaluating Migraine Prophylaxis Therapy trials that prompted the approval by the Food and Drug Administration for treatment of chronic migraines...

INTRODUCTION: Migraine is a common cause of emergency department (ED) visits. To date, there is no recommended drug of choice for pain management of these patients. In the present study, we aimed to evaluate the effectiveness of ketorolac and magnesium sulfate in this regard. METHODS: This is a cross-sectional study performed on all 18 - 60 year-old patients, visiting two different EDs with complaint of moderate to severe migraine headache. Patients were treated with 30 mg ketorolac in one hospital and 1 gram magnesium sulfate in the other...

Vagus nerve stimulation (VNS) has been reported to be effective in the abortive treatment of both migraine and cluster headache. Using validated animal models of acute dural-intracranial (migraine-like) and trigeminal-autonomic (cluster-like) head pain we tested whether VNS suppresses ongoing and nociceptive-evoked firing of trigeminocervical neurons to explain its abortive effects in migraine and cluster headache. Unilateral VNS was applied invasively via hook electrodes placed on the vagus nerve. A single dose of ipsilateral or contralateral VNS, to trigeminal recording and dural-stimulating side, suppressed ongoing spontaneous and noxious dural-evoked trigeminocervical neuronal firing...

PURPOSE OF REVIEW: The purpose of this review is to revise current evidence on trigemino-vascular system (TVS) neuropeptides as potential biomarkers for chronic primary headaches, mainly for chronic migraine (CM). RECENT FINDINGS: Within sensory neuropeptides, released by an activated trigeminal nerve, calcitonin gene-related peptide (CGRP) levels seem to be a good biomarker of acute migraine and somewhat sensitive and specific for CM. CGRP, however, is not increased in 20-30% of CM patients, which suggests that CGRP is not the only neuropeptide involved in migraine pain generation and maintenance...

BACKGROUND: In migraine, high rate repetitive transcranial magnetic stimulation (rTMS) has been reported to be effective, and β endorphin (BE) may have a role in headache relief. OBJECTIVE: To report the role of BE and its μ (MOR) and δ opioid receptors (DOR) in headache relief following high rate rTMS in migraine. METHODS: Ninety-three migraine patients having more than 4 attacks per month were included. 10 Hz rTMS (600 pulses in 10 trains) was delivered to left motor cortex; 3 sessions to 24 (group 1), 1 session to 22 (group II) and sham stimulation to 47 patients (group III)...

BACKGROUND: Common childhood pain conditions (non-migraine headache, migraine, recurrent abdominal pain, growing pains, low back pain) and persistent pains are often associated with each other and have significant implications in later life. Emerging evidence suggests additional associations between these pain conditions and restless legs syndrome, iron deficiency, anxiety and depression. The aim of this cross-sectional study in pediatric twin individuals and their siblings was to investigate these associations...

BACKGROUND: Both migraine and asthma are common health problems in the general population. However, the association between these two disorders is yet to be fully explored. OBJECTIVE: We examined whether adult patients with migraine are at a higher risk of asthma development. METHODS: We used data retrieved from the National Health Insurance Research Database in Taiwan to conduct this nationwide population-based cohort study. We identified 6647 patients aged 20-60 years who were newly diagnosed with migraine between 2000 and 2005 for the migraine group and identified 26 588 patients without migraine for the nonmigraine group...

OBJECTIVES: People with migraine and tension-type headache (TTH) have psychiatric comorbidities. We aimed to test differences in mental health constructs by type and frequency of primary headache and associated pain sensitivity. MATERIALS AND METHODS: Data on headache features, neuroticism (Eysenck Personality Questionnaire) and depression (Major Depression Inventory) were obtained from 547 individuals classified into chronic (≥15) or episodic (<15 headache days/month) and into pure migraine (n=43), pure tension type headache (TTH, n=97), migraine and TTH (n=83) and no headache diagnosis (controls, n=324) groups...

OBJECTIVE: In a cohort of patients diagnosed with cervical artery dissection (CeAD), to determine the proportion of patients aged ≥60 years and compare the frequency of characteristics (presenting symptoms, risk factors, and outcome) in patients aged <60 vs ≥60 years. METHODS: We combined data from 3 large cohorts of consecutive patients diagnosed with CeAD (i.e., Cervical Artery Dissection and Ischemic Stroke Patients-Plus consortium). We dichotomized cases into 2 groups, age ≥60 and <60 years, and compared clinical characteristics, risk factors, vascular features, and 3-month outcome between the groups...

OBJECTIVE: To evaluate the efficacy of remote nonpainful electrical upper arm skin stimulation in reducing migraine attack pain. METHODS: This is a prospective, double-blinded, randomized, crossover, sham-controlled trial. Migraineurs applied skin electrodes to the upper arm soon after attack onset for 20 minutes, at various pulse widths, and refrained from medications for 2 hours. Patients were asked to use the device for up to 20 attacks. RESULTS: In 71 patients (299 treatments) with evaluable data, 50% pain reduction was obtained for 64% of participants based on best of 200-μs, 150-μs, and 100-μs pulse width stimuli per individual vs 26% for sham stimuli...

BACKGROUND: DFN-02 is a novel intranasal spray formulation composed of sumatriptan 10 mg and a permeation-enhancing excipient comprised of 0.2% 1-O-n-Dodecyl-β-D-Maltopyranoside (DDM). This composition of DFN-02 allows sumatriptan to be rapidly absorbed into the systemic circulation and exhibit pharmacokinetics comparable to subcutaneously administered sumatriptan. Rapid rate of absorption is suggested to be important for optimal efficacy. The objective of this study was to evaluate the safety and tolerability of DFN-02 (10 mg) in the acute treatment of episodic migraine with and without aura over a 6-month period based on the incidence of treatment-emergent adverse events and the evaluation of results of clinical laboratory tests, vital signs, physical examination, and electrocardiograms...

Early in 1998, we (de Lecea et al., 1998) and others (Sakurai et al., 1998) described the same hypothalamic neuropeptides, respectively called the hypocretins or orexins, which were discovered using two different approaches. In December of that year, we published the subject of this commentary in the Journal of Neuroscience: a highly detailed anatomical description of the extensive axonal projections of the hypocretin/orexin neurons. Although the function of this system was unknown at the time, a large body of literature today attests that the hypocretin/orexin neuropeptides play important roles in multiple physiological functions, particularly in sleep/wake regulation...

We aimed to compare the effectiveness of bilateral and unilateral block application in chronic migraine patients and whether there were differences in their effectiveness retrospectively. In chronic migraine patients undergoing Greater occipital nerve (GON) block, mean number of days with pain per month before and after block, mean duration of pain in attacks (in hours), and mean Visual Analog Scale (VAS) in attack and pain severity were recorded from files. The patients underwent one block a week for the first 1 month, thereafter one block a month according to GON block protocol used by our institute...
