Meta Analysis
Cluster headache and the hypocretin receptor 2 reconsidered: a genetic association study and meta-analysis.
Cluster headache is a severe neurological disorder with a complex genetic background. A missense single nucleotide polymorphism (rs2653349; p.Ile308Val) in the HCRTR2 gene that encodes the hypocretin receptor 2 is the only genetic factor that is reported to be associated with cluster headache in different studies. However, as there are conflicting results between studies, we re-evaluated its role in cluster headache. ⋯ Although we did not find evidence for association of rs2653349 in our LUCA study, which is the largest investigated study population thus far, our meta-analysis provides genetic evidence for a role of HCRTR2 in cluster headache. Regardless, we feel that the association should be interpreted with caution as meta-analyses with individual populations that have limited power have diminished validity.

Review Case Reports
Oculomotor nerve tumors masquerading as recurrent painful ophthalmoplegic neuropathy: report of two cases and review of the literature.
In recurrent painful ophthalmoplegic neuropathy (RPON) that was previously termed as ophthalmoplegic migraine, enhancement of the ocular motor cranial nerves could be seen in the cisternal segment during the acute phase. However, various tumors involving the oculomotor nerve may mimic RPON. ⋯ It should be recognized that an incomplete recovery may occur during future attacks in patients with otherwise uncomplicated RPON. Follow-up MRIs are required to detect tumors involving the ocular motor cranial nerves, especially in patients with suspected RPON when the recovery is incomplete.

Comparative Study
Comparison of parenteral treatments of acute primary headache in a large academic emergency department cohort.
The objective of this article is to compare acute primary headache patient outcomes in those initially treated with parenteral opiates or non-opiate recommended headache medications in a large academic medical emergency department (ED). ⋯ Initial opiate use is associated with longer length of stay compared with non-opiate first-line recommended medications for acute primary headache in the ED. This association remained strong and significant even after multivariable adjustment for headache diagnosis and other possible confounders.

The objective of this article is to evaluate whether statin use and vitamin D status is associated with severe headache or migraine in a nationally representative sample. ⋯ Statin use in those with higher serum vitamin D levels is significantly associated with lower odds of having severe headache or migraine.

Migraine headache is one of the most common primary headache disorders and is three times more prevalent in women than in men, especially during the reproductive ages. The neurobiological basis of the female dominance has been partly established. The present study aimed to investigate the effect of gender on the headache manifestations in migraine patients. ⋯ Gender has an influence on the characteristics of the headache as well as on the associated symptoms in migraine patients, and this impact varies across the age groups, particularly in women.
