Randomized Controlled Trial
Space headache on Earth: head-down-tilted bed rest studies simulating outer-space microgravity.
Headache is a common symptom during space travel, both isolated and as part of space motion syndrome. Head-down-tilted bed rest (HDTBR) studies are used to simulate outer space microgravity on Earth, and allow countermeasure interventions such as artificial gravity and training protocols, aimed at restoring microgravity-induced physiological changes. ⋯ Simulated microgravity during HDTBR induces headache episodes, mostly on the first day. Countermeasures are useful in reducing headache severity and associated symptoms. Reversible, microgravity-induced cephalic fluid shift may cause headache, also on Earth. HDTBR can be used to study space headache on Earth.

Comparative Study
Field-testing of the ICHD-3 beta diagnostic criteria for classical trigeminal neuralgia.
We aimed to field-test the beta version of the third edition of the International Classification of Headache Disorders (ICHD-3 beta) diagnostic criteria for classical trigeminal neuralgia (TN). The proposed beta draft of the 11th version of the International Classification of Diseases (ICD-11 beta) is almost exclusively based on the ICHD-3 beta classification structure although slightly abbreviated. We compared sensitivity and specificity to ICHD-2 criteria, and evaluated the needs for revision. ⋯ ICHD-3 beta was not significantly different from ICHD-2 and both lacked sensitivity. A modification of the criteria improved the sensitivity greatly and is proposed for inclusion in the forthcoming ICHD-3.

Randomized Controlled Trial Multicenter Study
Safety and efficacy of peripheral nerve stimulation of the occipital nerves for the management of chronic migraine: long-term results from a randomized, multicenter, double-blinded, controlled study.
Recent studies evaluated short-term efficacy and safety of peripheral nerve stimulation (PNS) of the occipital nerves for managing chronic migraine. We present 52-week safety and efficacy results from an open-label extension of a randomized, sham-controlled trial. ⋯ Our results support the 12-month efficacy of PNS of the occipital nerves for headache pain and disability associated with chronic migraine. More emphasis on adverse event mitigation is needed in future research.

Randomized Controlled Trial
The influence of ictal cutaneous allodynia on the response to occipital transcutaneous electrical stimulation in chronic migraine and chronic tension-type headache: a randomized, sham-controlled study.
The objective of this article is to determine whether cutaneous allodynia (CA) influences the response to treatment with occipital transcutaneous electrical stimulation (OTES) in chronic migraine (CM) and chronic tension-type headache (CTTH). ⋯ Severe CA is associated with decreased response to treatment with OTES in patients with CM and CTTH.

Published data from 1998 revealed that most patients treated for migraine in an emergency department received opioids. Over the intervening years, a large body of evidence has emerged demonstrating the efficacy and safety of non-opioid alternatives. Expert opinion during these years has cautioned against use of opioids for migraine. Our objectives were to compare current frequency of use of various medications for acute migraine in US emergency departments with use of these same medications in 1998 and to identify factors independently associated with opioid use. ⋯ In spite of recommendations to the contrary, opioids are still used in more than half of all emergency department visits for migraine. Though use of meperidine has decreased markedly between 1998 and 2010, it has largely been replaced by hydromorphone. Opioid use in migraine visits is independently associated with prior visits to the same emergency department in the previous 12 months.
