Multicenter Study Clinical Trial
Clinical significance of brush allodynia in emergency patients with migraine.
Cutaneous brush allodynia may be a practical and readily assessable marker of progression of an acute migraine attack. We determined the relative frequency of this finding in emergency department (ED) patients with acute migraine and tested the hypothesis that the presence of cutaneous brush allodynia prior to initial treatment in the ED could predict poor 2-hour and 24-hour pain intensity outcomes. ⋯ Cutaneous brush allodynia is an uncommon finding in the ED, occurring in fewer than 1 in 5 migraineurs. It does not seem to have prognostic relevance for the ED-based management of the acute migraine attack.

To estimate the 1-year prevalence of tension-type headache (TTH) and the degree of the association of TTH with some sociodemographic characteristics of a representative sample of the adult population of Brazil. ⋯ This is the first nationwide epidemiological study of TTH in Brazil. The overall prevalence of TTH in Brazil is low, at 13%. TTH is significantly more prevalent in males and subjects with higher education level.

Reversible cerebral vasoconstriction syndrome (RCVS) usually presents with recurrent thunderclap headaches and is characterized by multifocal and reversible vasoconstriction of cerebral arteries that can sometimes evolve to severe cerebral ischemia and stroke. We describe the case of a patient who presented with a clinically typical RCVS and developed focal neurological symptoms and signs despite oral treatment with calcium channel blockers. Within hours of neurological deterioration, she was treated with intra-arterial milrinone, a phosphodiesterase inhibitor, which resulted in a rapid and sustained neurological improvement.

To develop the pharmacists' care of migraineurs scale (PCMS) and to evaluate its psychometric properties. ⋯ The PCMS demonstrated very good construct validity and reliability. While additional validity testing is warranted, the PCMS should allow for benchmarking in the evaluation of interventions designed to improve pharmacists' care to migraineurs and for identifying correlates to effective community pharmacist migraineur care.

Allodynia, a painful response to a usually nonpainful stimulus, is common in chronic migraine. The evaluation of allodynia can be important clinically. Dynamic mechanical allodynia (brush) testing has been shown to be both a simple and reliable way to evaluate allodynia. In this study, we show that self-administered brush allodynia testing at home is a feasible means of evaluating and recording allodynia in relationship to chronic migraine.
