Botulinum neurotoxin (BoNT) is a major therapeutic agent that is licensed in neurological indications, such as dystonia and spasticity. The BoNT family, which is produced in nature by clostridial bacteria, comprises several pharmacologically distinct proteins with distinct properties. In this review, we present an overview of the current therapeutic landscape and explore the diversity of BoNT proteins as future therapeutics. In recent years, novel indications have emerged in the fields of pain, migraine, overactive bladder, osteoarthritis, and wound healing...

Quantitative sensory testing (QST) is widely used to assess somatosensory function by application of controlled stimuli across a variety of modalities. The aim of the present meta-analysis is to synthesize QST results across a wide array of studies of patients with migraine to identify the QST parameters that are reliably different between patients with migraine and healthy controls. In addition, we aimed to determine whether such differences vary according to stimulus location. A comprehensive literature search (up to January 2017) was conducted, which included studies comparing QST parameters between patients with migraine and healthy controls...

REVIEW
Geoffrey A Lambert, Alessandro S Zagami
Migraine is a condition without apparent pathology. Its cardinal symptom is the prolonged excruciating headache. Theories about this pain have posited pathologies which run the gamut from neural to vascular to neurovascular, but no observations have detected a plausible pathology. We believe that no pathology can be found for migraine headache because none exists. Migraine is not driven by pathology - it is driven by neural events produced by triggers - or simply by neural noise- noise that has crossed a critical threshold...

In this work, we report the effects of incorporation of variable amounts (1-20 wt%) of sodium montmorillonite (MMT) into a siloxane-poly(ethylene oxide) hybrid hydrogel prepared by the sol-gel route. The aim was to control the nanostructural features of the nanocomposite, improve the release profile of the drug sodium diclofenac (SDCF), and optimize the swelling behavior of the hydrophilic matrix. The nanoscopic characteristics of the siloxane-crosslinked poly(ethylene oxide) network, the semi-crystallinity of the hybrid, and the intercalated or exfoliated structure of the clay were investigated by X-ray diffraction (XRD), small-angle X-ray scattering (SAXS), and differential scattering calorimetry (DSC)...

Pinja Leimuranta, Leonard Khiroug, Rashid Giniatullin
In this mini-review, we summarize recent discoveries and present new hypotheses on the role of cannabinoids in controlling trigeminal nociceptive system underlying migraine pain. Individual sections of this review cover key aspects of this topic, such as: (i) the current knowledge on the endocannabinoid system (ECS) with emphasis on expression of its components in migraine related structures; (ii) distinguishing peripheral from central site of action of cannabinoids, (iii) proposed mechanisms of migraine pain and control of nociceptive traffic by cannabinoids at the level of meninges and in brainstem, (iv) therapeutic targeting in migraine of monoacylglycerol lipase and fatty acid amide hydrolase, enzymes which control the level of endocannabinoids; (v) dual (possibly opposing) actions of cannabinoids via anti-nociceptive CB1 and CB2 and pro-nociceptive TRPV1 receptors...

Migraine has long been associated with disturbances of vision, especially migraine with aura. However, the eye plays an important role in sensory processing as well. We have found that the visual quality of life is reduced in migraine. In this review, we discuss how the migraine and eye pain pathways are similar and affect many of the common complaints which are seen in ophthalmology and neuro-ophthalmology offices, such as dry eye and postoperative eye pain. We also review other related phenomena, including visual snow and photophobia, which also are related to altered sensory processing in migraine...

Jyoti Mani, Shailender Madani
Background: Abdominal migraine (AM) is a common cause of chronic and recurrent abdominal pain in children. It is characterized by paroxysms of moderate to severe abdominal pain that is midline, periumbilical, or diffuse in location and accompanied by other symptoms including headache, anorexia, nausea, vomiting, or pallor. Despite the presence of comprehensive diagnostic criteria under Rome IV classification of functional gastrointestinal disorders (FGIDs) and International Classification of Headache Disorders, it continues to be an underdiagnosed entity...

Background Allodynia is prevalent in adults with migraine and has been associated with long disease duration and severe course. Studies of the pediatric population are sparse. The aim of this study was to evaluate the rate of cephalic cutaneous allodynia in children and adolescents within the first 6 months of migraine onset and to identify associated clinical and migraine-related parameters. Methods The electronic database of a tertiary pediatric headache clinic from 2014 to 2017 was retrospectively searched for all children and adolescents diagnosed with migraine headache within 6 months or less of symptom onset...

The pain sensation system is highly conserved among species, thus animal models have been used to investigate relevant tissues. The focus for head-specific pain has been on the primary nociceptive neurons in the trigeminal pathway, i.e. trigeminal ganglia. The secondary nociceptive neurons of the trigeminal pathway, trigeminal nucleus caudalis (TNC), have not been assessed. We expect different gene expression profiles compared to the homologous spinal cord dorsal horn (SDH), as several signalling substances provoke head-specific pain but not peripheral pain...

OBJECTIVE: The visual system has often been described to be sensitized in migraineurs, with light being perceived as aversive or even painful. One possible explanation for this altered perception is crosslinks between the visual and the trigeminonociceptive system. Visual stimulation in chronic migraineurs on the level of the brainstem might lead to enhanced activity within the spinal trigeminal nucleus (sTN) as the main site of trigeminal pain processing within this area. METHODS: Eighteen episodic migraineurs (EM), 17 chronic migraineurs (CM), and 19 healthy controls (HC) underwent one session of high-resolution brainstem imaging during which a rotating checkerboard was presented repeatedly as a visual stimulus...
