Headache
-
To study the clinical features of nummular headache (NH) and get an approach to its epidemiology. ⋯ NH emerges as a clear-cut clinical picture. It is a noninfrequent primary headache. The particular topography suggests the pain has a probable epicranial source conveyed by, or originated in, one/a few terminal branch(es) of the cutaneous nerves of the scalp.
-
To investigate clinical, MRI, and radioisotope findings and therapeutic outcome of the syndrome of spontaneous intracranial hypotension (SIH). ⋯ Patients with SIH have distinct MRI and sometimes radioisotope cisternographic abnormalities and generally respond favorably to conservative management.

Randomized Controlled Trial Clinical Trial
Electroacupuncture for tension-type headache on distal acupoints only: a randomized, controlled, crossover trial.
To investigate the efficacy of electroacupuncture, applied to distal acupoints only, for tension-type headache. ⋯ Electroacupuncture to distal points alone is effective for short-term symptomatic relief of tension-type headache.

Comparative Study
Validation of a brief nurse-administered migraine assessment tool.
To validate a brief tool for screening migraine. ⋯ This study showed good reliability and stability of a new, brief, nurse-administered migraine questionnaire. In addition, the study also showed that consistency in self-reporting analgesic overuse within individuals with headache is poor. This suggests the need for repeat questioning about analgesic overuse on subsequent appointments to ensure absence of analgesic overuse headache.

Case Reports
Migraine-associated seizures with recurrent and reversible magnetic resonance imaging abnormalities.
Migraine and epilepsy are highly comorbid, but the nature of their association remains unclear. Exceptionally, reversible brain magnetic resonance imaging (MRI) abnormalities following migraine and seizures have been reported. ⋯ Location of the abnormalities was always consistent with the neurologic deficits. The possibility that transient brain MRI abnormalities in a patient with migraine with aura followed by seizures may be due to migralepsy should be borne in mind to avoid misdiagnosis and potentially aggressive procedures.
