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.

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.

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.

We tested the computerised, structured medical record by entering and analysing the consecutive clinical sheets of primary headaches in the episodic forms (200) and chronic headache (200) and the corresponding output diagnoses of patients attending our Headache Centre. A diagnosis of one of the primary headache forms was obtained in 67.9% of cases. A certain diagnosis of primary headache plus that of a probable form was obtained in 24.4% of cases (12.7% represented by chronic migraine (CM) or chronic tension-type headache (CTTH)+probable medication overuse headache). ⋯ In the other cases, the ICHD-II classification does not allow the diagnoses of CM, CTTH or probable forms and medication overuse headache because the mandatory criteria for the diagnoses are too stringent and do not reflect modifications of the headache pattern in relation to its chronicity. These preliminary results underscore the usefulness of a computerised device based on the ICHD 2nd edition for diagnostic purposes in tertiary centres dedicated to headaches in clinical practice as well as its relevance for research. This computerised device may help to validate the new diagnostic criteria and to answer some emerging questions from the application of the new classification version, the relevance of which should be verified in clinical practice.
