Almotriptan and zolmitriptan in the acute treatment of migraine.

OBJECTIVE: To compare almotriptan and zolmitriptan in the treatment of acute migraine. METHODS: This multicentre, double-blind trial randomized adult migraineurs to almotriptan 12.5 mg (n = 532) or zolmitriptan 2.5 mg (n = 530) for the treatment of a single migraine attack. The primary end point was sustained pain free plus no adverse events (SNAE); other end points included pain relief and pain free at several time points, sustained pain free, headache recurrence, use of rescue medication, functional impairment, time lost because of migraine, treatment acceptability, and overall treatment satisfaction. RESULTS: No significant difference was seen in SNAE (almotriptan 29.2% vs zolmitriptan 31.8%) or the other efficacy end points measured. The incidence of triptan-associated AEs and triptan-associated central nervous system AEs was significantly lower for patients receiving almotriptan compared to zolmitriptan. CONCLUSIONS: Almotriptan and zolmitriptan were associated with similar efficacy and overall tolerability in the treatment of acute migraine. Almotriptan was associated with a significantly lower rate of triptan-associated AEs.

Gender ratio of migraine without aura: observations over time.

Migraine without aura is typically considered a female condition. The purpose of this study was to determine if there have been any changes in the female-to-male ratio of the disease over time. We included in the study all patients with migraine without aura (n = 3457) referred to the Parma University Headache Centre between 1976 and 1995. They were divided into subgroups with respect to gender and year-range of onset of migraine (before 1960, in the 1960s, in the 1970s, in the 1980s, and between 1990 and 1995). Gender ratio ranged from 3.6:1 (in patients with onset before 1960) to 2.8:1 (in patients with onset in the 1980s), with no statistically significant changes during the observation period.

Psychiatric comorbidity and headache: clinical and therapeutical aspects.

General population studies suggest a non-casual association (comorbidity) between migraine, major depression and anxiety disorders (panic attack disorder, obsessive-compulsive disorder, generalised anxiety disorder). The risk of developing affective and anxiety disorders is not increased uniformly in the different migraine subtypes, but it is more elevated in migraine with aura patients. The relationship between migraine and depression is "bi-directional" (i. e., migraineurs have a more than three-fold risk of developing depression compared with non-migraine patients, while depression patients that have never suffered from migraine before have a more than three-fold risk of developing migraine compared with nondepressed patients) and specific (i. e., the presence of migraine or severe non-migraine headache increases a patient's risk of developing depression or panic attack disorder, whereas the presence of depression or panic attack disorder is associated with a greater risk of developing migraine, but not severe non-migraine headache). Comorbidity with psychiatric disorders has also been described for chronic tension-type headache and for chronic daily headache, although these findings are based only on clinical population data.

Thirty years of headache research in Italy.

Over the last few decades, worldwide headache research has made very significant progress. Italy has played a prominent role in this research experience, through several groups of investigators that have regularly been conducting basically independent high-profile studies. A review of the headache literature in the last few decades shows that Italy, which has traditionally been among the countries at the frontline of headache research-nearly 10% of all the articles published in 1984 in Headache and Cephalalgia concerned studies conducted by Italian headache centres-is now second only to the United States. As many as 33 of the 243 articles published in the two journals in 2004 were from Italian research groups, accounting for 13.6% of the total. The next goal is to raise Italian headache research to increasingly higher scientific levels by capitalising on the skills and enthusiasm of young researchers.

Chronically evolving headaches: classification and terminology.

Chronic migraine appeared for the first time in the second edition of the International Classification of Headache Disorders (ICHD-II) in 2004, listed among the complications of migraine. Unfortunately, the diagnostic criteria of ICHD-II for this headache form tend to equate it with a migraine with a high frequency of attacks, rather than with an unfavourable evolution of migraine with loss of symptom-free intervals between attacks. On the other hand, the latter occurrence has increasingly been described in the last few years with the term "transformed migraine". Therefore, it seems advisable to carry out a revision of the ICHD-II in order to: (a) subdivide migraine at the three-digit level into infrequent episodic, frequent episodic and chronic migraine; and (b) introduce transformed migraine among the complications of migraine.

Epidemiology of typical and atypical craniofacial neuralgias.

Trigeminal neuralgia (TN) has a prevalence of 0.1-0.2 per thousand and an incidence ranging from about 4-5/100,000/year up to 20/100,000/year after age 60. The female-to-male ratio is about 3:2. A review of several case series shows that pain is more predominant on the right side, but the difference is not statistically significant. TN is significantly associated with arterial hypertension, Charcot-Marie-Tooth neuropathy, glossopharyngeal neuralgia (GN) and multiple sclerosis. GN has an incidence of 0.7/100,000/year and epidemiological studies have shown it to be less severe than previously thought. Post-herpetic neuralgia has a comparable incidence to idiopathic TN. The epidemiology of the central causes of facial pain is still unclear, but it is known that persistent idiopathic facial pain is a widespread, not easily manageable problem.

Validation of a questionnaire for the detection of cluster headache.

BACKGROUND: In the absence of biological markers, the diagnosis of cluster headache (CH) rests on clinical evidence as reported through ad-hoc interviews. OBJECTIVE: The aim of this study was to validate a 16-item self-administered questionnaire designed to screen CH cases. METHODS: The questions were based on the second edition of the International Headache Society classification (ICHD-II) criteria for CH (n = 12) and on specific disease features (n = 3). Answers to each question were either "Yes,""No," or "Don't know." The validity of this screening tool was assessed using a two-step procedure. In Step 1, the 16 questions were submitted to 30 healthy subjects with different cultural backgrounds to verify content clarity. In Step 2, the questionnaire was given to 71 patients (32 women and 39 men) aged 15 to 78 years (mean 37.5 years), who were seen at the University of Parma Headache Center with a diagnosis of CH (episodic, 17; chronic, 13), migraine (without aura, 18; with aura, 3), and tension-type headache (episodic, 16; chronic, 4) according to the ICHD-II criteria. Sensitivity, specificity, and the positive and negative predictive values were calculated for each question as measures of validity. RESULTS: Severity, unilaterality, and location of pain had the highest sensitivity (100%), but low (34.1%) or fairly low specificity (61.0% and 58.5%, respectively). In contrast, a positive response to lithium or verapamil had a 66.7% sensitivity and a 97.6% specificity. Sensitivity and specificity were 100% and 90.2% for duration of attacks (<180 to 240 minutes), and 90.0% and 92.7% for compulsory movements, respectively. The best discriminatory pattern for symptom detection was unilaterality of pain and the presence of at least five of the following seven features: pain severity and location, duration, frequency and daily recurrence of attacks, rhinorrhea and restlessness as accompanying symptoms. CONCLUSIONS: Our findings confirm that this questionnaire is a useful method for CH screening in epidemiological studies.

Headache classification: criticism and suggestions.

The International Classification of Headache Disorders 2nd Edition (ICHD-II), published in 2004, marks an unquestionable progress from the preceding 1988 edition, but the in-depth analysis it offers is not immune from drawbacks and shortcomings. First of all, it is still basically a classification of attacks and not of syndromes. For the migraine group, while the revised classification more accurately characterises migraine with aura, it fails to provide a sufficiently structured description of those forms of migraine without aura that over the years evolve to so-called daily chronic forms. These forms are not adequately recognised as chronic migraine, which ICHD-II includes among the complications of migraine. The inclusion of short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) in the cluster headache group is bound to generate some perplexity, while the recognition of new daily persistent headache (NDPH) included in the group of other primary headaches as a separate clinical entity appears somewhat premature. Doubts are also raised by the actual existence of triptan-overuse headache, which ICHD-II includes in Group 8 among medication-overuse headaches. Finally, the addition of headache attributed to psychiatric disorder, which is certainly a good option in perspective, is not yet supported by an adequate systematisation.

Cluster Headache↗

Cluster headache: symptomatic treatment.

The clinical management of cluster headache (CH) attacks requires a symptomatic treatment that is rapidly effective in resolving or significantly reducing symptoms. First-choice drugs for the symptomatic treatment of CH are subcutaneous sumatriptan at a dose of 6 mg and 100% oxygen inhalation at a rate of 7 l/min for no more than 15 min. Sumatriptan acts by suppressing pain and the accompanying autonomic phenomena, with no substantial differences in its mechanism of action between episodic and chronic CH. The drug can be used for prolonged periods without loss of efficacy or safety and its side-effects are generally mild or moderate. Oxygen inhalation has a number of advantages over drug therapy: it is free from side-effects, has no contraindications--unlike sumatriptan, it can be used in patients with cardiac, cerebral or peripheral vascular disease and with kidney, liver or lung disease--acts rapidly and can be administered several times a day. Its disadvantages are that it is scarcely practical and may induce a "rebound effect". Sumatriptan nasal spray, zolmitriptan and dihydroergotamine nasal spray are scarcely effective. After the introduction of sumatriptan, ergotamine tartrate has been relegated to a secondary role in the symptomatic treatment of CH. Among other non-drug and topical drug treatment options, hyperbaric oxygen therapy and the intranasal application of 10% cocaine hydrochloride and 10% lidocaine in the sphenopalatine fossa have also proved effective.

Headache screening and diagnosis.

In most cases, diagnosis of the various headache subtypes is possible through the accurate collection of medical history data. However, sometimes serious problems of differential diagnosis may be encountered. Therefore, the distinction between migraine without aura and tension-type headache is not always easy, the relationship between chronic migraine and medication overuse headache is a complex one, and differentiation of chronic tension-type headache vs. new daily-persistent headache is often problematic. A clear knowledge of the distinctive clinical features of the various headache subtypes is necessary to establish a correct diagnosis in the group of unilateral headaches with short-lived attacks and in the group of headaches with nocturnal onset.

Placebo-controlled comparison of effervescent acetylsalicylic acid, sumatriptan and ibuprofen in the treatment of migraine attacks.

Acetylsalicylic acid (ASA) in combination with metoclopramide has been frequently used in clinical trials in the acute treatment of migraine attacks. Recently the efficacy of a new high buffered formulation of 1000 mg effervescent ASA without metoclopramide compared to placebo has been shown. To further confirm the efficacy of this new formulation in comparison with a triptan and a nonsteroidal anti-inflammatory drug (ibuprofen) a three-fold crossover, double-blind, randomized trial with 312 patients was conducted in Germany, Italy and Spain. Effervescent ASA (1000 mg) was compared to encapsulated sumatriptan (50 mg), ibuprofen (400 mg) and placebo. The percentage of patients with reduction in headache severity from moderate or severe to mild or no pain (primary endpoint) was 52.5% for ASA, 60.2% for ibuprofen, 55.8% for sumatriptan and 30.6% for placebo. All active treatments were superior to placebo (P < 0.0001), whereas active treatments were not statistically different. The number of patients who were pain-free at 2 h was 27.1%, 33.2%, 37.1% and 12.6% for those treated with ASA, ibuprofen, sumatriptan or placebo, respectively. The difference between ASA and sumatriptan was statistically significant (P = 0.025). With respect to other secondary efficacy criteria and accompanying symptoms no statistically significant differences between ASA and ibuprofen or sumatriptan were found. Drug-related adverse events were reported in 4.1%, 5.7%, 6.6% and 4.5% of patients treated with ASA, ibuprofen sumatriptan or placebo. This study showed that 1000 mg effervescent ASA is as effective as 50 mg sumatriptan and 400 mg ibuprofen in the treatment of migraine attacks regarding headache relief from moderate/severe to mild/no pain at 2 h. Regarding pain-free at 2 h sumatriptan was most effective.

International Headache Society classification: new proposals about chronic headache.

In the International Headache Society (IHS) classification of 1988, chronic daily headache (CDH) forms are not exhaustively categorized. The forthcoming revision of the classification will include a number of CDH forms that had been reported prior to 1988 or have been identified after that date. In particular, chronic migraine will be added to the classification as a complication of migraine, provided that use of symptomatic drugs does not exceed 10 days per month. In addition to chronic cluster headache and chronic paroxysmal hemicrania, short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) and hemicrania continua will be comprised among CDH forms with short-lived attacks. Hypnic headache will be included in Group 4 ("Other primary headaches"). No additions will be made to the new IHS classification for forms such as new daily persistent headache (NDPH) and cervicogenic headache as proposed by Sjaastad.

Clinical observations on familial cluster headache.

Cluster headache (CH) has traditionally been considered a sporadic disease. Recently, an Italian study pointed out a risk of developing CH in the affected patients' firstdegree relatives that was increased 39-fold compared with the general population. The aims of this study were to investigate any possible differences in mean age at onset, clinical features and lifestyle between familial and non-familial CH cases. Among all CH patients referred to the Parma Headache Centre (n=691), we considered those who reported at least a first-degree relative with a probable diagnosis of CH in their family histories (n=30). CH diagnosis in the relatives was confirmed for 19 of the 30 patients. Each one of the 19 "familial cases" was matched by sex and age at the first visit (within 2 years) to two CH patients who did not report any family history for CH. The male:female ratio was 1.4:1 in the familial cases. Mean age at onset was significantly lower in women with familial CH than in those with non-familial CH. The study did not show any significant differences in symptoms between the two CH groups, such as pain location, accompanying symptoms, duration and frequency of attacks, and active periods. Our study seems to suggest that genetic factors play a role in the female gender, affecting age at onset of headache without modifying the clinical features.

Familial occurrence of migraine with aura in a population-based study.

OBJECTIVE: To better define a possible genetic basis for migraine with aura (MWA). METHODS: We investigated the familial occurrence of migraine with aura in a sample of (MWA) subjects recruited from an epidemiologic study of migraine with aura involving the general population. The sample with migraine with aura (n = 26) was selected out of a total of 1392 subjects (842 women and 550 men) representative of the general population aged 18 to 65 years in the southern Italian town of San Severo. A family history of migraine with aura was determined via direct interviews with all living first-degree relatives of the 26 subjects who could be reached by investigators, 119 people: 71 women and 48 men. The diagnosis of migraine with aura was made according to the 1988 International Headache Society (IHS) criteria. RESULTS: Of the 26 subjects with migraine with aura, 7 (6 women and 1 man) had a positive family history, with a total of 7 first-degree relatives affected by the disease (1 mother, 2 fathers, 1 brother, 1 sister, and 2 children). Based on the lifetime prevalence rate of migraine with aura (1.6%) in the San Severo general population, the relative risk of migraine with aura in the first-degree relatives of the subjects was 3.68 (4.16 for women and 2.77 for men). CONCLUSION: Our subjects' relative risk rate for familial occurrence of migraine with aura was similar to that reported by one investigator, but markedly lower than that reported by another group.

A prospective study of the headache phase in 32 migraine with aura patients.

For an accurate description of the clinical features of the headache phase in migraine with aura (MA) attacks, we thought it useful to conduct a prospective study of consecutively referred MA patients seeking treatment at the Headache Centre of the University of Parma Institute of Neurology. The case series included 32 patients (22 women and 10 men). At the time of the first visit, each patient was given a questionnaire to be filled in at the next MA attack. Six patients (four women and two men) had attacks of migraine aura without headache. Among the remaining 26 patients (18 women and eight men), the duration of the headache phase was <24 h in 23 (88.5%); pain location was bilateral in 14 (53.8%) and unilateral in 12, but occurring on the opposite side to aura only in one patient; pain intensity was mild or moderate in 13 (50.0%). The headache phase of MA appeared to have clinical features that differed widely from patient to patient and was consistent with the International Headache Society diagnostic criteria for migraine without aura in 26.9% of patients and for tension-type headache (TTH) in 23.1%.

Application of the International Headache Society classification criteria in 652 cluster headache patients.

We applied the International Headache Society (IHS) classification coding parameters to a study population of 652 cluster headache (CH) patients, in order to determine how many patients did not fulfil the diagnostic criteria for group 3.1 and to find out any diagnostic elements that could be changed in the upcoming revision of the classification to make it more relevant to current clinical practice. Ninety-nine patients were found to have cluster-like disorder (3.3), including 74 (74.7%) who did not fulfil the diagnostic criteria for CH, because either pain was not associated with any of the accompanying autonomic phenomena listed in the classification or it was not located orbitally, supraorbitally and/or temporally. A review of our total sample showed that 72.0% of patients reported frontal and occipital pain location; in 61.8%, 33.4% and 39.1% of cases, attacks were also accompanied by restlessness/agitation, nausea and photophobia, respectively. In a coding system that took into account the diagnostic elements that we considered in our study, group 3.1 of the existing IHS classification would actually include 51 of the 99 patients currently coded as 3.3.

Self-administered pain-relieving manoeuvres in primary headaches.

We investigated the use of self-administered pain-relieving manoeuvres on a sample of 400 patients with primary headaches--represented by an even distribution of migraine without aura (MO), migraine with aura (MA), episodic tension-type headache (TH), and cluster headache (CH)--consecutively seen at Padua and Parma Headache Centres. Manoeuvres on various regions of the head were used by 258 patients (65% of the cases). The most applied procedures were: compression (114 out of 382 manoeuvres; 30%), application of cold (27%), massage (25%) and application of heat (8%). A significant (P < 0.001) relationship was found between headache diagnoses and type of manoeuvre. In MO patients the application of cold (38% of the manoeuvres) and compression (36%), used mainly on the forehead and temples, prevailed; compression, mainly on the temples, was the most frequent procedure (44%) in MA patients. Massage on the temples and nape was the predominant manoeuvre (43%) in TH patients, whereas in the CH group, which more often required heterogeneous procedures, none of the above-mentioned manoeuvres was prevalent. Compression, as a diagnostic criterion for MO, had a sensitivity of 33% and a specificity of 86%; for the application of cold the figures were 36% and 84%, respectively. Massage had a sensitivity of 33% and a specificity of 80% for TH. The efficacy of the self-administered manoeuvres in reducing pain was scarce. Only 8% of the manoeuvres, in fact, resulted in a good or excellent pain control. Moreover, the efficacy of the manoeuvre was often momentary, wearing off when the manoeuvre stopped. In spite of this, 46% of the subjects used the manoeuvres constantly, at each attack.
