Spreading depolarization (SD) occurs alongside brain injuries and it can lead to neuronal damage. Therefore, pharmacological modulation of SD can constitute a therapeutic approach to reduce its detrimental effects and to improve the clinical outcome of patients. The major objective of this article was to produce a systematic review of all the drugs that have been tested against SD. Of the substances that have been examined, most have been shown to modulate certain SD characteristics. Only a few have succeeded in significantly inhibiting SD...

Migraine is a primary headache disorder characterized by recurrent attacks. Acetaminophen, nonsteroidal anti-inflammatory drugs, triptans, antiemetics, ergot alkaloids, and combination analgesics have evidence supporting their effectiveness in the treatment of migraine. Acetaminophen and nonsteroidal anti-inflammatory drugs are first-line treatments for mild to moderate migraines, whereas triptans are first-line treatments for moderate to severe migraines. Although triptans are effective, they may be expensive...

REVIEW
Till Sprenger, M Viana, C Tassorelli
A relatively high number of different medications is currently used for migraine prevention in clinical practice. Although these compounds were initially developed for other indications and differ in their mechanisms of action, some general themes can be identified from the mechanisms at play. Efficacious preventive drugs seem to either suppress excitatory nervous signaling via sodium and/or calcium receptors, facilitate GABAergic inhibition, reduce neuronal sensitization, block cortical spreading depression and/or reduce circulating levels of CGRP...

BACKGROUND: In 2016, a large meta-analysis brought the number of susceptibility loci for migraine to 38. While sub-type analysis for migraine without aura (MO) and migraine with aura (MA) found some loci showed specificity to MO, the study did not test the loci with respect to other subtypes of migraine. This study aimed to test the hypothesis that single nucleotide polymorphisms (SNPs) robustly associated with migraine are individually or collectively associated with menstrual migraine (MM)...

RATIONALE: Subarachnoid hemorrhage (SAH) is a common and serious disease and one of the most important differential diagnoses in the emergency department. PATIENT CONCERNS: A 39-year-old female patient with a 12 years' history of migraine, presented with a sudden headache combined with motor aphasia. Physical examination suggested probable positive neck resistance. SAH was confirmed by magnetic resonance imaging. In addition, spinal digital subtraction angiography and spinal vascular computed tomography angiography indicated spinal arteriovenous malformation (SAVM)...

BACKGROUND: Data on autonomic nervous system (ANS) activations in migraine patients are quite controversial, with previous studies reporting over- and underactivation of the sympathetic as well as parasympathetic nervous system. In the present study, we explicitly aimed to assess the cranial ANS in migraine patients compared to healthy controls by applying the cold pressor test to a cohort of migraine patients in the interictal phase and measuring the pupillary response. METHODS: In this prospective observational study, a strong sympathetic stimulus was applied to 20 patients with episodic migraine in the interictal phase and 20 matched controls without migraine, whereby each participant dipped the left hand into ice-cold (4 °C) water for a maximum of 5 min (cold pressor test)...

Background Migraine with aura may mimic an acute ischemic stroke, so that an improper administration of thrombolytic treatment can expose migrainous patients to severe adverse effects. Methods This systematic review quantifies the relevance of migraine with aura among stroke mimics, checking for thrombolysis' safety in these patients. We reviewed the literature after 1995, distinguishing from studies dealing with stroke mimics treated with systemic thrombolysis and those who were not treated with systemic thrombolysis...

The Drosophila gene c12.2 was isolated in a screen examining mRNA binding proteins. Drosophila c12.2 is the mouse Vwa8 homolog. Various genome-wide associated studies have linked human Vwa8 to both neurological and oncological pathologies, which include autism, bipolar disorder, comorbid migraine, and acute myeloid leukemia, however, the function and role of the VWA8 protein remain poorly understood. To further analyze the Vwa8 gene in mouse, gene structure, protein homology modeling, and gene expression patterns were examined throughout mouse development...

INTRODUCTION: Migraine variant disorders of childhood include benign paroxysmal torticollis of infancy (BPTI) and benign paroxysmal vertigo of childhood (BPVC). This study aimed to review our experience with BPTI and BPVC and determine the incidence of children transitioning between each of these disorders and to vestibular migraine (VM). METHODS: We retrospectively reviewed the medical records of patients seen at the Balance and Vestibular Program at Boston Children's Hospital between January 2012 and December 2016 who were diagnosed with BPTI, BPVC, and/or VM...

Several factors that modulate migraine, a common primary headache disorder, also affect susceptibility to cortical spreading depolarization (CSD). CSD is a wave of neuronal and glial depolarization and thought to underlie the migraine aura and possibly headache. Here, we tested whether caffeine, known to alleviate or trigger headache after acute exposure or chronic use/withdrawal, respectively, modulates CSD. We injected C57BL/6J mice with caffeine once (30, 60, or 120 mg/kg; i.p.) ( acute) or twice per day for one or two weeks ( chronic)...

The aim of this investigation was to examine whether chronic periodontitis (CP) is a risk indicator of chronic migraine (CM). We performed a case-control study consisted of 102 cases (patients diagnosed with CM) and 91 controls (non-CM individuals) matched by age and gender. Full-mouth periodontal charts, demographic, medical, clinical, as well as neurological data were obtained. In addition, high sensitive C-reactive protein serum levels were determined from blood samples of both cases (taken during migraine interictal period) and controls...

BACKGROUND: Chronic rhinosinusitis (CRS) is associated with productivity losses exceeding US$13 billion annually. Although pain is well known to significantly affect patient productivity in other diseases, its economic impact on CRS-related lost productivity has not been examined. The objective of this study was to determine whether CRS-related facial pain correlates with lost productivity in patients with CRS. METHODS: Seventy patients with CRS were enrolled in a cross-sectional investigation...

REVIEW
Pei-Chun Lai, Yen-Ta Huang
Droperidol is a short-acting, potent dopamine D2 antagonist that can pass through the blood-brain barrier. A black box warning was issued for droperidol by the United States Food and Drug Administration in 2001 because of a risk of development of torsades de pointes induced by QT prolongation. Many experts feel that the incidence of arrhythmia is overestimated, and low-dose droperidol is almost always used by anesthesiologists for postoperative nausea and vomiting. In this review, we used evidence-based analysis to appraise high-quality studies with a low risk of bias published after 2001 on the use of droperidol in the emergency department (ED)...
