Case Reports
Facial pain radiating upwards: could the pain of epicrania fugax start in the lower face?
Epicrania fugax (EF) is characterized by painful paroxysms starting in a particular area of the head, and rapidly radiating forwards or backwards through the territories of different nerves. In former clinical descriptions, the pain moved between the posterior scalp (C2) and the frontal or periorbital area (V1), either in forward or backward direction. ⋯ There seems to be a facial variant of EF. These observations could not only expand the clinical spectrum of EF but also enlarge the differential diagnosis of facial pain.

Randomized Controlled Trial Multicenter Study Comparative Study
AVP-825 breath-powered intranasal delivery system containing 22 mg sumatriptan powder vs 100 mg oral sumatriptan in the acute treatment of migraines (The COMPASS study): a comparative randomized clinical trial across multiple attacks.
The objective of this study was to compare the efficacy, tolerability, and safety of AVP-825, an investigational bi-directional breath-powered intranasal delivery system containing low-dose (22 mg) sumatriptan powder, vs 100 mg oral sumatriptan for acute treatment of migraine in a double-dummy, randomized comparative efficacy clinical trial allowing treatment across multiple migraine attacks. ⋯ AVP-825 (containing 22 mg sumatriptan nasal powder) provided statistically significantly greater reduction of migraine pain intensity over the first 30 minutes following treatment, and greater rates of pain relief and pain freedom within 15 minutes, compared with 100 mg oral sumatriptan. Sustained pain relief and pain freedom through 24 and 48 hours was achieved in a similar percentage of attacks for both treatments, despite substantially lower total systemic drug exposure with AVP-825. Treatment was well tolerated, with statistically significantly fewer atypical sensations with AVP-825.

This review aims to understand the prevalence of premonitory symptoms in migraine, postulate their mechanisms, and compare these with functional imaging studies. A thorough literature review was conducted using PubMed for prevalence studies of premonitory symptoms in migraine and functional imaging studies in the premonitory phase. The majority of studies have been retrospective reporting a prevalence of 7-88% for premonitory symptoms in migraine. ⋯ Hypothalamic involvement can explain many of the premonitory symptoms. Activation of the the brainstem structures and hypothalamus before pain suggests a pivotal role of these structures in the pathogenesis of migraine. Hypersensitivity to light and occurrence of nausea in migraine is associated with activation of central brain structures involved in these pathways, and this can occur in the absence of pain.

Migraine is associated with a number of cardiometabolic risk factors including abnormalities in lipid metabolism. However, little is known about these associations among pregnant migraineurs. We conducted the present study to evaluate the extent to which altered lipid profiles are associated with history of migraine among pregnant women. ⋯ Pregnant migraineurs had elevated odds of dyslipidemia, particularly hypercholesterolemia, elevated LDL, and total cholesterol : HDL ratio as compared with pregnant non-migraineurs. The observed associations were more pronounced among obese migraineurs. Our findings add to the accumulating evidence of adverse cardiometabolic risk profiles among migraineurs and extend these associations to pregnant women.

Chronic migraine with medication overuse (CM-MO) impairs quality of life (QoL) and causes disability. Psychosocial variables such as depressive symptomatology, self-efficacy, and social support have been sparingly investigated, and their impact on disability and QoL is unknown. ⋯ Adding information on psychosocial variables to headache features improved our ability to understand disability and QoL of CM-MO patients. We deem that the inclusion of psychosocial variables in standard evaluation protocols may contribute to the global assessment of CM-MO patients, and eventually to their success in reducing the personal and social impact of this condition. Future longitudinal studies are needed to confirm this hypothesis.
