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.

Case Reports
The lesser occipital nerve visualized by high-resolution sonography--normal and initial suspect findings.
The lesser occipital nerve (LON) supplies the lateral part of the occiput and is-together with the greater occipital nerve (GON)-involved in headache pathogenesis. While the GON was described in high-resolution ultrasound (HRUS), the same does not apply to the LON. We aimed at characterizing the LON in HRUS, and present cases of suspect findings in the course of the LON identified by HRUS. ⋯ We confirm the possibility of visualization of the LON using HRUS. HRUS may be a helpful adjunct tool in the assessment of patients with atypical headache.

Migraine is a common disabling condition that affects approximately 15% of the population. Several genome-wide association studies have attempted to identify susceptibility variants involved in migraine, reporting several candidate loci for the disorder. ⋯ Our study provides suggestive replication, in a Spanish migraine with aura sample, of four genome-wide association study findings previously reported in common migraine. However, larger sample sets should be explored to confirm our results.

In 2013 the International Headache Society published the third International Classification of Headache Disorders beta-version, ICHD-3 beta. Its structure is identical to that of the present proposed version of the International Classification of Diseases (ICD-11), although slightly abbreviated to fulfill the needs of ICD-11. In the following, only ICHD-3 beta is mentioned, but findings regarding the validity of ICHD-3 beta categories are equally relevant to the forthcoming ICD-11. Here we field-tested the criteria for 1.2 migraine with aura (MA), 1.2.1 migraine with typical aura (MTA), 1.2.3 hemiplegic migraine, 1.2.2 migraine with brainstem aura, and the alternative criteria A1.2 MA and A1.2.1 MTA. ⋯ The new criteria in ICHD-3 beta/proposed ICD-11 for 1.2 MA, 1.2.1 MTA, 1.2.3.1 FHM and 1.2.3.2 SHM have more desirable properties than ICHD-2 and the ICHD-3 beta alternative criteria. The criteria for 1.2.2 migraine with brainstem aura should be more restrictive.
