We aimed to report 6 new cases of bifocal nummular headache (NH), showing their clinical characteristics and comparing them with those formerly described. ⋯ Although not frequently found, some patients may have bifocal or multifocal NH.

Evidence has accumulated in recent years indicating structural, physiologic, and biochemical alterations in the brain of patients with chronic migraine (CM). Altered pharmacologic responses to opioids and other analgesics have also been reported. Structural or morphologic changes include reduced cortical gray matter of the pain processing areas of the brain and iron accumulation in the periaqueductal gray matter (PAG), red nucleus, and basal ganglia structures. ⋯ Suppression of cortical spreading depression by these agents is correlated with the dosages and the duration of treatment. The beneficial effect of botulinum toxin in CM may be due to its antinociceptive effect. Changes in the glutamate and calcitonin gene-related peptide at the peripheral nerve endings reduce peripheral sensitization, which eventually leads to reduced central sensitization.

Randomized Controlled Trial Multicenter Study
A double-blind placebo-controlled pilot study of sublingual feverfew and ginger (LipiGesic™ M) in the treatment of migraine.
Therapeutic needs of migraineurs vary considerably from patient to patient and even attack to attack. Some attacks require high-end therapy, while other attacks have treatment needs that are less immediate. While triptans are considered the "gold standard" of migraine therapy, they do have limitations and many patients are seeking other therapeutic alternatives. In 2005, an open-label study of feverfew/ginger suggested efficacy for attacks of migraine treated early during the mild headache phase of the attack. ⋯ Sublingual feverfew/ginger appears safe and effective as a first-line abortive treatment for a population of migraineurs who frequently experience mild headache prior to the onset of moderate to severe headache.

Multicenter Study Comparative Study Clinical Trial
Multi-center comparison of response to a single tablet of sumatriptan 85 mg and naproxen 500 mg vs usual therapy treating multiple migraine attacks as measured by the completeness of response survey.
To investigate a broad definition of migraine resolution that extends beyond specific migraine-associated diagnostic symptoms as measured by the Completeness of Response Survey. ⋯ NCT00893737.

Migraine is an episodic brain disorder that is characterized by recurrent attacks of severe unilateral headache that are accompanied by various neurological symptoms. In addition, many patients have what is called an aura with visual and sensory disturbances. The majority of patients are female, suggesting that female hormones play an important role in the pathophysiology of the disorder. ⋯ Findings from genetic and animal experiments on gender differences in migraine are discussed. Recently, a role for glutamate also came forward from a genome-wide association study in common migraine. By deciphering genetic and pathogenic migraine pathways, it can be expected that in the near future we will better understand mechanisms behind the female preponderance in migraine.
