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.

Trigeminal autonomic cephalalgias (TACs) and hemicrania continua (HC) are relatively rare but clinically rather well-defined primary headaches. Despite the existence of clear-cut diagnostic criteria (The International Classification of Headache Disorders, 2nd edition - ICHD-II) and several therapeutic guidelines, errors in workup and treatment of these conditions are frequent in clinical practice. We set out to review all available published data on mismanagement of TACs and HC patients in order to understand and avoid its causes. ⋯ Even when the clinical picture is clear-cut, TACs and HC are frequently not recognized and/or mistaken for other disorders, not only by general physicians, dentists and ENT surgeons, but also by neurologists and headache specialists. This seems to be due to limited knowledge of the specific characteristics and variants of these disorders, and it results in the unnecessary prescription of ineffective and sometimes invasive treatments which may have negative consequences for patients. Greater knowledge of and education about these disorders, among both primary care physicians and headache specialists, might contribute to improving the quality of life of TACs and HC patients.

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.

Randomized Controlled Trial
Advice alone versus structured detoxification programmes for complicated medication overuse headache (MOH): a prospective, randomized, open-label trial.
The aim of this study was to compare the effectiveness of an educational strategy (advice to withdraw the overused medication/s) with that of two structured pharmacological detoxification programmes in patients with complicated medication overuse headache (MOH) plus migraine. ⋯ Inpatient withdrawal is significantly more effective than advice alone or an outpatient strategy in complicated MOH patients.
