OBJECTIVE To investigate the relationship between the presence of active trigger points (TrPs), craniocervical posture, and clinical features (frequency, intensity, and duration) in patients with migraine. DESIGN A cross-sectional study. METHODS Fifty patients with migraine (90% women; age, 34.1 years) participated. Clinical data regarding migraine(More)
This study examined the effect of GMP in two models of depression in mice. The immobility times in the forced swimming test (FST) and in the tail suspension test (TST) were significantly reduced by GMP (dose range: 5-50 mg/kg and 5-100 mg/kg, i.p., respectively), without accompanying changes in ambulation in an open-field. I.c.v. injection of GMP (320-480(More)
Migraine is a complex neurological disorder with a clear neurogenic inflammatory component apparently including enhanced nitric oxide (NO) formation. Excessive NO amounts possibly contributing to migraine are derived from increased expression and activity of inducible NO synthase (iNOS). We tested the hypothesis that two functional, clinically relevant iNOS(More)
Matrix metalloproteinases (MMP) are involved in the disruption of blood-brain barrier (BBB) during migraine attacks. In the present study, we hypothesized that two functional polymorphisms (C(-1306)T and C(-735)T) in MMP-2 gene and MMP-2 haplotypes are associated with migraine and modify MMP-2 and tissue inhibitor of MMP (TIMP)-2 levels in migraine.(More)
We investigated whether three relevant polymorphisms (C-1562T, microsatellite -90(CA)(14-24), and Q279R) in the MMP-9 gene, or MMP-9 haplotypes, are associated with migraine and affect MMP-9 and tissue inhibitor of MMPs (TIMP)-1 levels in patients with migraine. We studied 102 healthy women (controls) and 187 women with migraine (141 without aura - MWA, and(More)
OBJECTIVES Because there is only one study to our knowledge on the prevalence of restless legs syndrome (RLS) in sub-Saharan Africa and RLS is more common in patients with some pain syndromes, we aimed to determine the prevalence of RLS in a population with chronic pain in Maputo, Mozambique. METHODS Our study was conducted in the Pain Unit of the Central(More)
Vascular endothelial growth factor (VEGF) production is regulated by growth factors and inflammatory cytokines, and VEGF plays a role in migraine. We examined for the first time whether three functional polymorphisms in the promoter region of VEGF gene (C(-2578)A, G(-1154)A, and G(-634)C) and VEGF haplotypes are associated with migraine. We studied 114(More)
BACKGROUND We compared the circulating levels of matrix metalloproteinase (MMP)-2, MMP-9, tissue inhibitors of metalloproteinase (TIMP)-1, TIMP-2, and MMP-9/TIMP-1 and MMP-2/TIMP-2 ratios in migraine patients without aura (MWA) and in migraine patients with aura (MA) with those found in healthy subjects (controls). METHODS We studied 80 migraine (40 MWA(More)
There is strong evidence implicating nitric oxide (NO) in the pathophysiology of migraine and aura. Therefore, genetic polymorphisms in the endothelial NO synthase (eNOS) gene have been studied as candidate markers for migraine susceptibility. We compared for the first time the distribution of eNOS haplotypes including the three clinically relevant eNOS(More)
We present four cases of headache with variable intensity, located in close proximity to a craniotomy incision which was performed for non-traumatic reasons. Since manual palpation of the scar often triggers pain, and infiltration with local anesthetics reduce or abolish the pain in some patients, we suggest that neuromas or nerve entrapment in the scars,(More)
