Characteristics of Headache After an Intracranial Endovascular Procedure: A Prospective Observational Study.
Two editions of the International Classification of Headache Disorders (ICHD) diagnostic criteria for "Headache attributed to an intracranial endovascular procedure" have been published, in 2004 and 2013.(1,2) Despite studies that have suggested that the former is not very practical, the ICHD-3 beta did not contain major changes. Moreover, so far no consensus exists regarding characteristics of headache after intracranial endovascular procedure. Thus, there is a need for sound suggestions to improve the ICHD-3 beta diagnostic criteria. ⋯ Most cases of markedly worsening headaches and new-onset headaches started within 24 hours and persisted longer than that specified in the ICHD-3 beta diagnostic criteria. Moreover, considering that some items are not very practical, the ICHD-3 beta diagnostic criteria should be revised in the light of recent literature reports.

Unnecessary confusion still surrounds the use of combined hormonal contraceptives (CHCs) in the setting of migraine with aura (MwA). Clearing this confusion is a key issue for headache specialists, since most women with migraine have menstrual-related migraine (MRM), and some CHCs can prevent this particularly severe migraine. Their use, however, is still restricted by current guidelines due to concerns of increased stroke risk - concerns that originated over half a century ago in the era of high dose contraceptives. ⋯ This article clarifies the stroke risk of CHCs and examines their impact on migraine. It also examines how stroke risk is altered by the estrogen content of the CHC, by contributing factors such as smoking, age and hypertension, and by aura frequency. And finally, it puts these risks into a meaningful context with a risk/benefit assessment.

To investigate differences in widespread pressure pain hyperalgesia in the trigemino-cervical and extra-trigeminal (distant pain-free) regions in women with frequent episodic (FETTH) and chronic (CTTH) tension-type headache. ⋯ Current results suggest the presence of similar local and widespread pressure hyperalgesia, not associated with anxiety or depression, in women with FETTH and CTTH supporting that localized and central manifestations are involved in both the episodic and chronic forms of tension-type headache.

Craniocervical dystonia is a focal or segmental dystonia in its distribution, classically known as spasmodic torticollis when in its pure cervical presentation. Although craniocervical dystonia has been recognized as a possible cause of headache since the publication of the second version of International Classification of Headache Disorders, there are few studies about this entity. ⋯ Headache attributed to craniocervical dystonia has been poorly studied. There is a need for more studies to evaluate its characteristics and treatment.

Management of chronic migraine (CM) or new daily persistent headache (NDPH) in those who require aggressive outpatient and inpatient treatment is challenging. Ketamine has been suggested as a new treatment for this intractable population. ⋯ Subanesthetic ketamine infusions may be beneficial in individuals with CM or NDPH who have failed other aggressive treatments. Controlled trials may confirm this, and further studies may be useful in elucidating more robust benefit in a less refractory patient population.
