Randomized Controlled Trial
Randomized controlled trial of treatment expectation and intravenous fluid in pediatric migraine.
(1) The primary objectives were (1) to assess the response to intravenous (IV) fluid in children presenting to the ED with migraine and; (2) to assess the effect of treatment expectation on the response to I. ⋯ The overall decrease in pain with IV fluid is small and clinically insignificant. Treatment expectation did not significantly influence headache relief at 30 minutes with IV fluid hydration in children or adolescents with migraine in the ED. The average relief of headache with IV fluid alone was small; however, a clinically meaningful response was observed in 17.8%. Recurrence of headache is common in 33% after ED discharge.

There is evidence that folate metabolism has a role in migraine pathophysiology, particularly in the migraine with aura (MA) subtype. In this study, we investigate whether two non-synonymous single nucleotide polymorphisms (SNPs), rs1950902 (C401T; R134K) and rs2236225 (G1958A; R653Q), in MTHF dehydrogenase (MTHFD1) are associated with migraine in an Australian case-control population. ⋯ We find no evidence for association of the MTHFD1 R134K and R653Q polymorphisms with migraine in our Australian case-control population. However, as folate metabolism appears to be important in migraine, particularly with respect to the aura component, future studies using high throughput methods to expand the number of SNPs in folate-related genes genotyped and investigation of interactions between SNPs may be justified.
