Cephalalgia : an international journal of headache

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.

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.

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.

Neurophysiological investigations have demonstrated that there are unique fluctuations in the migraine brain functional activity between the ictal and interictal periods. Here we investigated the possibility that there are fluctuations over time also in whole brain morphometry of patients affected by episodic migraine without aura (MO). Twenty-four patients with untreated MO underwent 3T MRI scans during (n = 10) or between attacks (n = 14) and were compared to a group of 15 healthy volunteers (HVs). ⋯ Ictally, GM density increased within the left temporal pole, bilateral insula, and right lenticular nuclei, but no areas exhibited decreased GM density. These morphometric GM changes between ictal and interictal phases suggest that abnormal structural plasticity may be an important mechanism of migraine pathology. Given the functional neuroanatomy of these areas, our findings suggest that migraine is a condition associated with global dysfunction of multisensory integration and memory processing.
