This study evaluates osmophobia (defined as an unpleasant perception, during a headache attack, of odours that are non-aversive or even pleasurable outside the attacks) in connection with the diagnosis of primary headaches. We recruited 775 patients from our Headache Centre (566 females, 209 males; age 38+/-12 years), of whom 477 were migraineurs without aura (MO), 92 with aura (MA), 135 had episodic tension-type headache (ETTH), 44 episodic cluster headache (ECH), 2 chronic paroxysmal hemicrania (CPH) and 25 other primary headaches (OPHs: 12 primary stabbing headaches, 2 primary cough headaches, 3 primary exertional headaches, 2 primary headaches associated with sexual activity, 3 hypnic headaches, 2 primary thunderclap headaches and 1 hemicrania continua). ⋯ We conclude that osmophobia is a very specific marker to discriminate adequately between migraine (MO and MA) and ETTH; moreover, from this limited series it seems to be a good discriminant also for OPHs, and for CH patients not sharing neurovegetative symptoms with migraine. Therefore, osmophobia should be considered a good candidate as a new criterion for the diagnosis of migraine.

The aim of the study was to determine the frequency of clinical allodynia, osmophobia and red ear syndrome in a young population. Medical records of the children admitted for headache between 1 December 2004 and 31 March 2005 were consecutively studied. A questionnaire was used to find the prevalence of allodynia, osmophobia and red ear syndrome. ⋯ We classified migraine in 57%, other primary headaches in 25% and secondary headaches in about 18%. The presence of ipsilateral clinical allodynia was 14.5% in migraine, osmophobia in 20% of migraine and red ear syndrome in about 24% of migraine cases and they were absent in the other two headache groups. Our study shows that features like osmophobia, allodynia and red ear syndrome are not uncommon in migraine while they are absent in other types of headache.

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.

Padua, the cradle of modern medicine: Bernardino Ramazzini (1633-1714) on headaches.
A prominent historian of Medicine, Henry Sigerist, quoted the Padua Medical School as "the cradle of modern medicine". This opinion is currently accepted worldwide. A short outline on the contribution of the Padua Medical School to the development of medical knowledge in its "golden age" is given. In this context, the work of a prominent figure of the 17(th) century Padua University and the founder of Occupational Medicine, Bernardino Ramazzini, is considered, with focus on his interest in headache.

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.
