Randomized Controlled Trial Clinical Trial
Posterior hypothalamic and brainstem activation in hemicrania continua.
To determine the brain structures involved in mediating the pain of hemicrania continua using positron emission tomography. ⋯ This study demonstrated activations of various subcortical structures, in particular the posterior hypothalamus and the dorsal rostral pons. If posterior hypothalamic and brainstem activation are considered as markers of trigeminal autonomic headaches and migrainous syndromes, respectively, then the activation pattern demonstrated in hemicrania continua mirrors the clinical phenotype, with its overlap with trigeminal autonomic headaches and migraine.

Clinical Trial
Oral transmucosal fentanyl citrate for the treatment of migraine headache pain in outpatients: a case series.
Migraine headache pain that does not respond to traditional antimigraine medications frequently requires treatment in the emergency department (ED) with parenteral opioids. Rapid onset of pain relief in an outpatient setting for migraine headache is the primary objective of patients and clinicians. Oral transmucosal fentanyl citrate (OTFC; ACTIQ) is a novel opioid product designed to deliver rapid analgesia to patients who experience breakthrough pain (BTP). ⋯ OTFC rapidly and significantly relieved acute, refractory migraine pain in outpatients, prevented the need for an ED visit, and was associated with high patient satisfaction ratings. The rapid onset of migraine headache pain relief in this case series is consistent with the analgesic effect reported with the use of OTFC in patients with BTP. OTFC was well tolerated in these patients who had a history of tolerating parenteral opioids in the ED when experiencing refractory migraine pain and had been treated with outpatient opioid therapies in attempts to manage their migraine pain. OTFC may be effective for outpatient treatment of acute, refractory migraine headache pain. Further controlled studies are warranted.

Case Reports
Tolosa-Hunt syndrome due to actinomycosis of the cavernous sinus: the infectious hypothesis revisited.
The Tolosa-Hunt syndrome is characterized by ophthalmoplegia with unilateral severe retro-orbital pain associated to a granulomatous inflammatory process occupying the cavernous sinus or the superior orbital fissure. The etiology is unknown and diagnosis is based upon a clinical response to steroid treatment and exclusion of neoplasm, trauma, aneurysms, infectious, and inflammatory diseases. ⋯ The present case suggests that the International Classification of Headache Disorders (2nd edition) definition of Tolosa-Hunt syndrome does not reflect the complexity of the syndrome and that some cases of secondary painful ophthalmoplegias can fit the criteria for the primary form. Since the biopsy can only rarely be performed, we agree with other authors that clinical and radiological follow-up should be performed for at least 2 years. Moreover, we propose that in patients with painful ophthalmoplegia having transient response to steroid therapy, a trial with antibiotic therapy should be taken into account.

Multicenter Study
Validity and reliability of the Turkish Migraine Disability Assessment (MIDAS) questionnaire.
The aim of this study is to assess the comprehensibility, internal consistency, patient-physician reliability, test-retest reliability, and validity of Turkish version of Migraine Disability Assessment (MIDAS) questionnaire in patients with headache. ⋯ These findings demonstrated that the Turkish translation is equivalent to the English version of MIDAS in terms of internal consistency, test-retest reliability, and validity. Physicians can reliably use the Turkish translation of the MIDAS questionnaire in defining the severity of illness and its treatment strategy when applied as a self-administered report by migraine patients themselves.

The main objective of this study is to determine whether change in migraine frequency is correlated with a denervation pattern of the corrugator muscle after local botulinum toxin type A injections. ⋯ Relaxation of the corrugator muscles is not solely responsible for the pain relief in migraine patients treated with botulinum toxin type A.
