The prevalence and the clinical features of chronic daily headache (CDH) were studied in 968 children and adolescents observed during a period of one year in the Headache Centre of the Anna Meyer Paediatric Hospital of Florence. Nine hundred and forty-four patients (97.52%) had primary headache according to ICHD-II, 24 subjects had secondary headache and 56 patients had CDH (5.93% of primary headaches). ⋯ According to the ICHD-II, headaches were classified as chronic migraine in 10 patients (1.5.2 ICHD-II), chronic tension-type headache in 36 (2.3 ICHD-II), new daily persistent headache in 8 (4.8 ICHD-II) and 2 patients reported mixed pattern (chronic migraine+chronic tension type headache). Medication overuse was not implicated in our patients.

The social perception of headache, everywhere at low levels in industrialised countries, becomes totally absent in developing ones. Headache disorders came into the World Health Organization's strategic priorities after publication of the 2001 World Health Report. Among the leading causes of disability, migraine was ranked 19th for adults of both sexes together and 12th for females. ⋯ An International Team for Specialist Education (ITSE) has been created to train physicians from all over the world through the acquisition of a university level Master Degree in Headache Medicine. Once trained as headache specialists, physicians will become trainers, offering education in this field to other health care providers in their own countries. In this way they will give life to a cultural chain raising awareness locally of headache, its burden and its medical control.

Most women with migraine improve during pregnancy. Some women have their first attack. Migraine often recurs postpartum and can begin for the first time. ⋯ While medication use should be limited, it is not absolutely contraindicated in pregnancy. Nonpharmacologic treatment is the ideal solution; however, analgesics such as acetaminophen and opioids can be used on a limited basis. Preventive therapy is a last resort.

Chronic daily headache (CDH) is a heterogeneous group of headaches that includes primary and secondary varieties. Primary CDH is a frequent entity that probably affects 4-5% of the population. ⋯ Analgesics, ergots and triptan overuse are frequent in all types of CDH. We revise recent insights into the epidemiology, pathophysiology, clinical characteristics and prognosis of CDH.

A relationship between migraine and patent foramen ovale (PFO) has been observed in relatively small series of patients so far. Furthermore, the exact mechanism underlying such an association remains unknown. In the present study we determined the prevalence of PFO by contrast-enhanced transcranial Doppler (TCD) in a group of 260 patients with migraine with aura (MA+), 74 patients with migraine without aura (MA-), and 38 patients with cluster headache (CH). ⋯ Finally, among the 15 patients who had a history of at least one migraine attack occurring during a Valsalva maneuver only one subject turned out to be PFO-carrier. Our findings confirm previous observations of a link between MA+, CH, and PFO. They also suggest that such an association is independent on migraine clinical phenotype and is probably unrelated to the pathogenic mechanism of paradoxical embolism.
