Cluster headache and lifestyle: remarks on a population of 374 male patients.
To investigate the relation between cluster headache (CH) and lifestyle, some lifestyle factors were considered in a population of 374 CH male patients consecutively referred to the same headache center, including 306 with episodic CH, 22 with chronic CH unremitting from onset, 20 with chronic CH evolved from episodic, and 26 with CH periodicity undetermined CH patients had jobs involving greater responsibilities and were more frequently self-employed than controls. In addition, their past medical histories often reported head injury, either with loss of consciousness (13.4%) or without loss of consciousness (23.5% of cases). As regards nonessential consumption habits, both cigarette-smoking and coffee and alcohol intake were more frequently reported in CH patients than in the general population, with a higher prevalence in chronic CH as opposed to episodic CH sufferers. In particular, smokers accounted for 78.9% of episodic CH patients and 87.8% of chronic CH patients--12.9% of episodic CH patients and 19.6% of chronic CH patients smoked over 30 cigarettes a day. Alcohol abuse was reported in 16.2% of episodic and 26.8% of chronic CH patients, while coffee abuse was reported in 6.9% of episodic and in 36.6% of chronic CH patients. Rather than pointing to a single lifestyle factor directly implicated in CH onset, my review suggests a common trend among CH patients to overindulge in certain living habits.

Possible predictive factors in the prognosis of migraine with aura.
In order to identify possible predictive factors in the prognosis of migraine with aura (MA), we conducted a review at 10 to 20 years from referral on a sample of 77 MA patients (51 F, 26 M) consecutively seen for the first time at the University of Parma Headache Center. Based on the date of the last MA attack reported by these patients, we divided them into two study groups: a group of 22 patients "with remission of the disease," i.e. attack-free for at least 2 years at the end of the follow-up study; and a group of 55 patients "without remission of the disease," i.e. still having attacks in the last 2 years of the follow-up study. A comparative analysis of the MA clinical features observed in the two groups at the time of the patients' first visit to our Center enabled us to identify a number of favorable prognostic indicators, namely: a family history of parents with MA, the absence of other associated forms of primary headache, and the absence of both natural and artificial light stimulation as trigger factors.

Effectiveness of lamotrigine in the prophylaxis of migraine with aura: an open pilot study.
We report a small open pilot study to evaluate the efficacy of lamotrigine (100 mg/day) in the prevention of migraine with aura attacks. We studied 24 patients affected by migraine with aura with a high frequency of attacks. Following a 1-month run-in period, the patients took lamotrigine for 3 months. Mean attack number per month was reduced from 6.1 +/- 4.1 during the run-in period to 0.7 +/- 1.3 at the 3rd month of treatment (p < 0.0001). In 13 out of 21 patients who completed the study, the attacks were completely abolished at the 3rd month of treatment, while only one patient was completely unresponsive to the drug. Lamotrigine seems worthy of a controlled trial as prophylaxis of a migraine with aura.

Serotonin metabolism in cluster headache.
Despite some evidence of the involvement of the serotonergic system in cluster headache (CH) pathophysiology, the serotonin (5HT) metabolism has so far been poorly studied. The aim of this study was to investigate plasma and platelet levels of 5HT and 5-hydroxyindoleacetic acid (5HIAA) in CH patients in the active period of the disease. Nineteen CH sufferers and 17 sex- and age-matched healthy controls were studied. CH patients showed significantly higher plasma levels of 5HT and 5HIAA compared to controls (5HT: 5.7+/-6.1 ng/ml vs 0.2+/-0.2 ng/ml; p=0.02; 5HIAA: 34.7+/-46.1 ng/ml vs 0.6+/-0.7 ng/ml; p=0.004). In platelet 5HT levels were slightly reduced in CH patients in comparison with those of control subjects (662.4+/-522.3 ng/10(-8) platelets vs 832.4+/-587.9 ng/10(-8) platelets; n.s.) and 5HIAA levels resulted significantly lower in CH sufferers than in control subjects (3.2+/-2.6 ng/10(-8) platelets vs 6.7+/-4.8 ng/10(-8) platelets; p=0.04). Our data suggest that CH is characterized by an increase of plasma serotonergic metabolism that could reflect an involvement of the central serotonergic system in the pathogenesis of CH.

Gender ratio of cluster headache over the years: a possible role of changes in lifestyle.
Changes in the male-to-female (M/F) ratio of cluster headache (CH) over the years were investigated through a comparative analysis of the distribution of the disease by sex and decade of onset in 482 patients (374M and 108F). Variations over the last few decades were also investigated in the employment rate, level of school education, smoking habit, and coffee and alcohol intake of the population living in the same area as the CH patients. The M/F ratio has fallen from 6.2:1 for patients with CH onset before 1960, to 5.6:1, 4.3:1, 3.0:1, and 2.1:1 for patients with CH onset in the 1960s, 1970s, 1980s, and 1990s, respectively. Correspondingly, in those same decades, the M/F ratio has fallen from 2.6:1 to 2.4:1, 2.2:1, and 1.7:1, respectively, for the employment rate, and from 8.6:1 to 7.8:1, 3.3:1, 2.5:1, and 1.9:1 for the smoking habit. Such a close correlation suggests that the significant changes that have occurred over the last few decades in the lifestyle of both sexes--and particularly that of women--may have played a major role in altering the gender ratio of CH.

Migraine with aura: a review of 81 patients at 10-20 years' follow-up.
We investigated the evolution over time of migraine with aura (MA) in a number of MA patients consecutively referred to the University of Parma Headache Center in the period 1976-86. The follow-up period chosen for our review of the clinical condition of patients varied from a minimum of 10 years to a maximum of 20 years. The study group comprised 81 patients (55F, 26M), 21 of them (14.2%) with at least one parent with MA. Migraine without aura (MO) was also present in 29.6% of the patients studied. Currently, 35% of patients (29.4% F, 46.1% M) have been free from attacks for at least 1 year and 19.4% (13.6% F, 30.8% M) for over 5 years. Moreover, the frequency of attacks has decreased considerably in 54.4% of cases (50% F, 63.7% M); it has increased in only 25% (26.1% F, 22.7% M). The headache has disappeared completely in 11.1% of patients (8.0% F, 18.2% M); it has become less severe in 36.2% and more severe in only 5.5%. The results of our investigation point to a favorable evolution of MA over time.

Long-term outcome of migraine.
Migraine prevalence increases from childhood up until 40 years of age, and thereafter declines. Several hypotheses can be advanced to explain the decrease in migraine with advancing age: (i) favorable effect of preventive treatments; (ii) increased mortality in migraineurs (due to higher vulnerability to other fatal diseases); (iii) cohort effect (increased incidence in young subjects); (iv) spontaneous remission. The first two theses are poorly supported by data in the literature. Although a cohort effect may exist, a spontaneous remission of migraine in middle and old age (at least partially due to the loss of sex hormone changes after the menopause in females) is the more likely hypothesis. In a small subgroup of patients (most of them drug abusers), migraine has a "malignant" course and changes into chronic daily headache. The risk factors for a poor outcome of migraine have been little studied. In a case-control study, we found that a history of head trauma and a long duration of contraceptive intake were risk factors for a bad outcome, whilst a long duration of prophylactic treatments had a protective effect.

Effectiveness of ibuprofen-arginine in the treatment of acute migraine attacks.
The purpose of this study was to evaluate the effectiveness of a new formulation of ibuprofen (ibuprofen-arginine [IA]) in the treatment of migraine attacks. This is a faster absorbed formulation as compared with ibuprofen alone. The rapidity of action is considered to be a crucial factor in the treatment of migraine attacks. Forty migraine patients participated in this multicenter, double-blind, crossover, randomized, placebo-controlled trial. Each patient was treated with a single oral dose of IA 400 mg or placebo during two consecutive migraine attacks. The results confirm the efficacy of IA, with a significant (p < 0.05) improvement in pain relief at 30 min after treatment. A statistically significant (p < 0.001) reduction in pain intensity was observed at 1, 2, 4 and 6 h after treatment with ibuprofen as compared with placebo. IA was well tolerated and our data indicate that this new formulation of ibuprofen is valuable in the treatment of acute migraine attacks.

Treatment of menstrual migraine.
Because of its pathophysiological and clinical peculiarities, true menstrual migraine (MM) (i.e. migraine starting exclusively between the days immediately before and immediately after the first day of the menstrual cycle) requires an ad hoc management different from that of other migraines. The paucity of well-conducted, controlled clinical trials and the lack of a universally accepted definition of MM have meant that the treatment of MM is still largely empirical. In our clinical practice, we adopt a sequential therapeutic approach, including the following steps: (i) acute attack drugs (sumatriptan, ergot derivatives, NSAIDs); (ii) intermittent prophylaxis with ergot derivatives or NSAIDs; (iii) oestrogen supplementation with percutaneous or transdermal oestradiol (100 microg patches); (iv) antioestrogen agents (danazol, tamoxifen).

Classification of chronic daily headache by International Headache Society criteria: limits and new proposals.
We conducted a retrospective study of 150 patients with chronic daily headache (CDH) to determine how to categorize their headache according to the classification of the International Headache Society (IHS). All patients were first evaluated at Parma and Pavia Headache Centres (from January 1992 to March 1993) and had had headache for at least 15 days a month during the previous 6 months. Four patients were thereafter excluded due to poor reliability. The 146 patients who met our CDH criteria (92 with and 54 without clear-cut migraine attacks) could be classified into four groups: (i) chronic tension-type headache (CTTH)--27 patients; (ii) coexisting migraine plus CTTH--65 patients; (iii) unclassifiable daily headache--27 patients; and (iv) migraine and an unclassifiable interval headache--27 patients. Seventy-two percent of patients with CDH had migraine as the initial form of their headache. We therefore propose to revise the IHS classification for migraine, taking into account its evolution, and add two subcategories, migraine with interparoxysmal headache and chronic migraine.

[Classification of primary headache and International Headache Society diagnostic criteria 1988: critical review].
Following a short analysis of leading principles of the classification and diagnostic criteria of headaches of the International Headache Society (IHS) and a brief description of its nosography of primary headaches, some still debated issues are discussed. The IHS classification shows a good inter-observer reliability both at one- and two-digit levels, even though validation studies are lacking. On the basis of researches carried out in recent years on the evolution of cluster headache, on chronic daily headache, on a possible third diagnostic level of migraine without aura, and on the painful phase of migraine with aura, some proposals of revision of the IHS classification are suggested.

International Headache Society classification: interobserver reliability in the diagnosis of primary headaches.
We assessed interobserver reliability of the International Headache Society (IHS) classification for diagnosis of primary headaches. The study was performed on 103 patients consecutively seen at two Headache Centres. Each patient was given a structured interview recorded on videotape. Four experienced clinicians then reviewed the interviews separately and made a diagnosis of headache according to IHS criteria at the one- and two-digit levels. At both the one- and the two-digit level the agreement was substantial (Kappa = 0.74 and 0.65, respectively). The analysis of reliability for each of nine items necessary for diagnosis showed an agreement ranging from substantial (Kappa = 0.69) to almost perfect (Kappa = 0.89). Our results indicate that the IHS classification has a good reliability for the diagnosis of primary headaches at the one- and two-digit levels.

Characteristics of headache at menopause: a clinico-epidemiologic study.
The prevalence and characteristics of primary headaches in a large sample of postmenopausal women were investigated. Seventy-six out of 556 women (13.7%) were affected by headache of either the migraine or tension type. In 82% of cases onset had preceded the menopause. The postmenopausal course of headaches with a premenopausal onset differed according to type of headache and type of menopause. Indeed, while migraine improved in almost two-thirds of cases, tension-type headache worsened or did not change in 70% of cases. However, in women who had undergone surgical ovariectomy, the natural course of migraine was worse than in those who had a physiological menopause (P = 0.003). Among the symptoms covered by the Kuppermann Index, only anxiety and insomnia were correlated with headache. The favourable course of migraine in the postmenopausal period can be attributed primarily to the absence of variations in sex hormone levels although psychological factors also seem to play a fundamental role.

An epidemiological approach to the nosography of chronic daily headache.
Chronic daily headache (CDH), a heterogeneous group of headaches, includes different forms that occur daily, or almost daily, over a prolonged period of time. The nosography of this group is still a matter of debate, and in the most recent classification of the IHS (1988) only a few types of CDH are included: chronic tension-type headache, coexisting migraine. This study is an epidemiological approach to identifying the clinical features of CDH and the possible factors involved in changing episodic headache in CDH. Ninety CDH outpatients were investigated using a computerized record chart. The main observed forms were: (a) chronic tension-type headache--migraine with interparoxysmal headache, an evolved form of migraine in which a constant low severity headache develops between attacks; (b) transformed migraine, an evolved form of migraine with progressive worsening of the disease which reaches the level of continuous pain with the disappearance of typical migraine attacks. Interval headaches in migraine with interparoxysmal headache partly fulfil the IHS criteria for chronic tension-type headache. Analgesic drug abuse plays a prominent role in inducing CDH and in determining its clinical features.

Accompanying symptoms of cluster attacks: their relevance to the diagnostic criteria.
Two-hundred-and-fifty-one consecutive cluster headache (CH) patients referred to the Pavia and Parma Headache Centers were evaluated in order to verify the presence and recurrence of one or more autonomic symptoms. Data obtained show that in 2.8% of patients cluster attacks were not accompanied by localized autonomic symptoms, thus confirming the report of Ekbom. We observed a high prevalence of photophobia, nausea and vomiting. The IHS diagnostic criteria for CH may need to be modified. The high frequency of "general" autonomic symptoms seems to suggest a component of "central" drive in the physiopathology of cluster headache.
