Randomized Controlled Trial Multicenter Study
Frovatriptan and rizatriptan economic EVAluation: the FREEVA study.
The present pharmacoeconomic study compared the direct and indirect costs of using frovatriptan versus rizatriptan in the acute treatment of migraine. ⋯ Within the limitations of this model analysis, frovatriptan was found to be significantly more cost-effective than rizatriptan. This outcome can be explained by the lower acquisition cost of frovatriptan, the need for fewer doses, and the loss of fewer working hours. This finding could drive selection of the most appropriate oral treatment for acute migraine attacks based on both individual patient's needs and the cost-effectiveness of the available drugs.

Randomized Controlled Trial
Headache and mechanical sensitization of human pericranial muscles after repeated intake of monosodium glutamate (MSG).
A single intake of monosodium glutamate (MSG) may cause headache and increased muscle sensitivity. We conducted a double-blinded, placebo-controlled, crossover study to examine the effect of repeated MSG intake on spontaneous pain, mechanical sensitivity of masticatory muscles, side effects, and blood pressure. ⋯ In conclusion, MSG induced mechanical sensitization in masseter muscle and adverse effects such as headache and short-lasting blood pressure elevation for which tolerance did not develop over 5 days of MSG intake.

The role of migraine as an independent risk factor for cardiovascular events has been debated for several years, while it is more established for ischemic stroke. Recently, new studies have examined the likelihood of migraine to determine cardiovascular events, supporting the hypothesis of a predominant role in patients with migraine with aura, the risk including both sexes. In the literature, multiple pathophysiological mechanisms are described to explain this association, and are here discussed. Furthermore, the emerging evidence that a higher headache frequency and long-term migraine may worsen the cardio-metabolic profile in migraineurs (e.g. with a higher Framingham risk score and risk of developing atherosclerosis, insulin resistance and metabolic syndrome) makes it increasingly necessary to reduce the number and severity of attacks, not only to alleviate the painful symptoms, but also to improve the prognosis in these patients.

Randomized Controlled Trial
Lidocaine injection of pericranial myofascial trigger points in the treatment of frequent episodic tension-type headache.
The present study aimed to evaluate the efficacy of local lidocaine injections into the myofascial trigger points (TPs) located at the pericranial muscles in patients with episodic tension-type headache (ETTH). ⋯ Local lidocaine injections into the myofascial TPs located in the pericranial muscles could be considered as an effective alternative treatment for ETTH.

Headache only triggered by coughing is a rather uncommon condition. The aim of the present review is to present an overview of the diagnosis, clinical characteristics, pathophysiology and treatment of both primary and symptomatic cough headache and discuss other relevant headache disorders affected by coughing. The diagnosis of primary cough headache is made when headache is brought on and occurs only in association with coughing, straining or a Valsalva manoeuvre and in the absence of any abnormalities on neuro-imaging. ⋯ Other frequently reported causes include miscellaneous posterior fossa pathology, carotid or vertebrobasilar disease and cerebral aneurysms. Consequently, diagnostic neuroimaging is key in the diagnosis of cough-related headache and guides treatment. Besides primary and symptomatic cough headache, several other both primary and secondary headache disorders exist where coughing acts as a trigger or aggravator of headache symptomatology.
