Headache and anxiety-depressive disorder comorbidity: the HADAS study.

Psychiatric comorbidity (prevalence and types) was tested in a naturalistic sample of adult patients with pure migraine without aura, and in two control groups of patients, one experiencing pure tension-type headache and the other combined migraine and tension-type headaches. The study population included 374 patients (158, 110 and 106) from nine Italian secondary and tertiary centres. Psychiatric comorbidity was recorded through structured interview and also screened with the Mini International Neuropsychiatry Interview (MINI). Only anxiety and depression were investigated. Psychiatric disorders were reported by 49 patients (14.6%; 10.9% of patients with migraine, 12.8% of those with tension-type headache and 21.4% of those with combined migraine and tension-type headaches). The MINI interview detected a depressive episode in 59.9% of patients with migraine, 68.3% of patients with tension-type headache and 69.6% of patients with combined migraine and tension-type headaches. Depression subtypes were significantly different across groups (p=0.03). Anxiety (mostly generalised) was reported by 18.4% of patients with migraine, 19.3% of patients with tension-type headache, and 18.4% of patients with combined migraine and tension-type headaches. The values for panic disturbance were 12.7, 5.5 and 14.2, and those for obsessive-compulsive disorders were 2.3, 1.1 and 9.4% (p=0.009). Based on these results, psychopathology of primary headache can be a reflection of the burden of the disease rather than a hallmark of a specific headache category.

Naratriptan in the short-term prophylaxis of pure menstrual migraine.

Menstrual migraines are particularly difficult-totreat. Few studies on the use of triptans in short-term prophylaxis of menstrually related migraine have been recently conducted, but evidences of triptans' efficacy in the specific case of pure menstrual migraine (PMM) are lacking. The aim of this study is to explore the efficacy and tolerability of naratriptan as short-term prophylaxis of pure menstrual migraine (PMM) attacks. A multi-centre, open, non comparative, pilot six-month study was conducted in women, aged 18 years or older, with regular menstrual cycles and with a history of migraine without aura exclusively associated to the perimenstrual period. After an observation period of three months, patients took for three consecutive menstrual cycles oral naratriptan 1 mg twice daily, starting two days before the expected onset of menstruation and continuing for six days. Ninety-eight women with a history of PMM were screened for study participation, and 61 entered the study. Fifty-nine comprised the intent-to-treat population. The mean number of PMM attacks decreased from 3.5+/-1.4 in the 3-month observation period to 1.6+/-1.3 in the 3-month treatment with naratriptan. The pecentage of responders (subjects who recorded a decrease-equal or more than 50%-in the mean number of attacks) was 61.4%. A tendency towards a decrease in headache severity and in the presence of associated symptoms was observed during treatment. At least one adverse event during the treatment period was reported by 19 patients (31.1%). No serious adverse events occurred. Naratriptan may be an effective and safe treatment option in the short-prophylaxis of PMM.

An epidemiological study to assess migraine prevalence in a sample of Italian population presenting to their GPs.

This multicentre, observational, cross-sectional study was conducted to determine migraine prevalence in a sample of population presenting to their GPs. The study covered all the patients who visited the GPs practice, for any reason, on 5 consecutive days of 2 different weeks. A total of 71,588 patients were interviewed by 902 GPs. The prevalence of migraine in this sample was 11.6%.

Efficacy and tolerability of sumatriptan in the treatment of multiple migraine attacks.

This cross-over, double blind, randomized, multicentre study evaluated the consistency of efficacy and safety of oral sumatriptan in 233 migraneurs. The patients received 50 mg oral sumatriptan or placebo for the treatment of 12 migraine attacks. Within each group of 4 attacks, three were treated with sumatriptan and one with placebo, according to a randomization list. Over all the attacks, the efficacy rate was statistically significant for sumatriptan against placebo at 2 or 4 hours (2 hours: sumatriptan 60%, PLO 38%, p < 0.001; 4 hours sumatriptan 79%, PLO 47%, p < 0.001). Oral sumatriptan was similarly effective at relieving the associated symptoms and at reducing clinical disability in most attacks. The incidence of adverse events did not differ between treatment groups. All the events recorded were mild to moderate as intensity and resolved spontaneously.

The epidemiology of migraine: a retrospective study in Italian emergency departments.

This study was conducted to measure the frequency of contact with emergency departments in Italy because of migraine, and to compare the initial diagnosi s of headache with the diagnosis after application of the International Headache Society (IHS) criteria. A retrospective observational method was used, consisting of an analysis of the records of patients admitted to nine Italian emergency departments during different 4-month periods in 1994. Comparison of the initial diagnosis with the diagnosis after application of the IHS diagnostic criteria was performed. More than 31 million emergency department contacts were reported in Italy during 1994. In the same year, 543 630 patients visited the nine emergency departments enrolled in the study, with 169 569 of these contacts occurring in the 4-month period analyzed in the study. We excluded from the analysis all cases of secondary headache fully recognized at the emergency department admission (ie, traumas, intracranial pathology, systemic diseases). The total number of patients included in our analysis was 1043 (0.6%). The 934 patients who could be fully evaluated were initially classified as having migraine; cluster headache; headache not otherwise specified; or diagnosed in the emergency department as suffering from headache, but reclassified by other departments as suffering from a different disease. After retrospective application of the IHS classification, the diagnostic distribution was modified, revealing that 18% of patients with migraine and 5% with cluster headaches had previously been classified as having headache not otherwise specified; a further 6% of cases with migraine and 0.4% of patients with cluster headache had previously been classified as having secondary headaches. The diagnosis of headache not otherwise specified was made with notable frequency, indicating the limits of emergency department logs and the difficulty in carrying out a retrospective analysis and reassessment of diagnosis. The majority (88%) of patients assessed had not taken drugs for headache in the 48 hours before the emergency department contact, suggesting that in Italy emergency departments are used instead of a visit to the general practitioner. Nonsteroidal anti-inflammatory drugs were the most frequently prescribed drugs in the emergency departments for this group of diagnoses. The research revealed, on the one hand, that headache is a numerically significant phenomenon in the emergency department setting and, on the other, the need to apply prospective designs to this kind of survey.

Oral sumatriptan compared with placebo in the acute treatment of migraine.

This multicentre, double-blind, parallel-group study compared the efficacy, safety and tolerability of oral sumatriptan, given as a new film-coated tablet, with placebo in the acute treatment of migraine. Patients were randomised unequally (1:2) to receive placebo or sumatriptan. Eighty-eight patients received placebo (plus an optional dose 2 h later if the headache persisted plus a further optional dose for recurrence within 24 h) and 162 patients received sumatriptan 100 mg (plus an optional 100 mg dose at 2 h and an optional 100 mg dose within 24 h). Sumatriptan was significantly more effective than placebo at relieving headache (defined as reduction in severity from severe or moderate pain to mild or no pain) at 2 h (51% versus 31%, P = 0.003) and 4 h (71% versus 35%, P < 0.001). Fewer sumatriptan-treated patients required a second dose compared with placebo-treated patients (49% versus 74%, P < 0.001). More sumatriptan-treated patients were completely pain free compared with placebo-treated patients at both 2 h (24% versus 12%) and 4 h (48% versus 18). Patients receiving sumatriptan reported earlier onset of headache relief than patients receiving placebo. Headache relief in sumatriptan-treated patients was similar, irrespective of the type of migraine (with or without aura) or the time of treatment < or = 4 h or > 4 h after onset of migraine). Sumatriptan was more effective than placebo at relieving nausea, vomiting and photophobia/phonophobia. Few patients were evaluable for treatment of headache recurrence, and statistical analysis was not possible.(ABSTRACT TRUNCATED AT 250 WORDS)

[Center monitoring and management of data bases]. / Monitoraggio dei centri e gestione del data base.

In this article the authors show the correct method to gather together clinical data. First they explain how to compile clinical files (five cards) and how to maintain the centres and monitor them. The initial quality of the data is increased by the creating of a structure with "regional" and "central" monitors. Thirdly the authors explain data management: how to code and enter data, how to check its correctness and lastly data base authorization.
