Headache
-
To perform a prospective epidemiological study of headache in a rural community in Oman, assessing prevalence, symptom profile, and health care utilization pattern. ⋯ This prospective study shows that headache is also highly prevalent in this community. Migraine and tension-type headache have the same prevalence, but the sex distribution for migraine is different from that observed in the Western world. Tension-type headache prevalence was substantially lower than that observed in other parts of the world. Frequent headaches were as common as in other population-based studies worldwide. Analgesic use/overuse probably also coexisted with headache, because self-medication was quite common.

Randomized Controlled Trial Comparative Study Clinical Trial
Intravenous dipyrone in the acute treatment of migraine without aura and migraine with aura: a randomized, double blind, placebo controlled study.
Dipyrone (Metamizol) has been used in the acute treatment of migraines in Brazil. Some investigators have found it to be a highly effective medication for migraine pain and associated symptoms. ⋯ Dipyrone is an effective drug for the relief of acute migraine pain and associated symptoms.

Randomized Controlled Trial Comparative Study Clinical Trial
Migraine with aura versus migraine without aura: pain intensity and associated symptom intensities after placebo.
To compare the intensity of pain and associated symptoms after placebo administration in patients with migraine with aura and migraine without aura. ⋯ Our findings suggest that studies comparing placebo against an active drug should use stratification according to the presence versus absence of aura.

To examine the lifetime prevalence and other characteristics of recurrent primary headaches in twins. ⋯ There is no twin-singleton or monozygotic-dizygotic difference for the risk of migraine. In tension-type headache, twins seem to have a lower risk than singletons, and this is especially true for monozygotic twins.
