RESUMO
Our study examines the effectiveness of an educational approach to migraine patients. A course in migraine education was set up for 30 patients suffering from this disease; meetings were structured taking into consideration specific educational aims, with parameters evaluated before the course, at the end of the course and at a 3-month follow-up. The results, particularly the increase in the migraineurs' knowledge of their disease and the decrease in the use of symptomatic drugs, suggest the effectiveness of the course. Furthermore, our study suggests that there is a need to build educational processes into therapeutic protocols, as they enable patients to manage their chronic diseases more correctly.

This observational study was designed to examine the pattern of sumatriptan use in patients with cluster headache using more than the recommended daily dose of subcutaneously injected (s.c.) sumatriptan. Thirteen patients suffering from episodic cluster headache were asked to record the characteristics of their attacks and drug intake for 1 year. All reported a high daily frequency of attacks (more than 3 per day) and the related overuse of s.c. sumatriptan. The results show that the overall incidence of adverse events among patients receiving sumatriptan injections for the treatment of cluster headache is low. The extended administration of this drug in episodic cluster headache did not result in tolerance problems or tachyphylaxis. Only 4 patients experienced minor adverse events and recovered more slowly than the others. They suffered from migraine without aura and cluster headache, and showed a family history of migraine. Even though they must be viewed with caution, due to the observational nature of the study and the low number of patients included, these results suggest that the profile of sumatriptan may differ in cluster headache compared with migraine.

Forty patients aged 65-80 with minor-medium signs of brain aging were treated for 6 months with daily 90 mg doses of nimodipine. Treatment was well tolerated in that the minor side effects reported by a few of the patients never required withdrawal of the drug. Treatment proved useful, as shown by a variety of mental tests, in 69.5% of cases. In 20% conditions remained unchanged and in 9.5% further deterioration was observed. The authors conclude that nimodipine may be considered a useful therapeutic resource for phenomena of brain aging.

This italian multicentre, double blind, parallel groups study compared the efficacy, safety and tolerability of oral sumatriptan, given as new film-coated tablet, with placebo in the acute treatment of migraine. 88 Patients received placebo and 162 patients received sumatriptan 100 mg (plus an optional dose 2 h later if the headache persisted plus a further optional dose for recurrence within 24 h). Sumatriptan was significantly more effective than placebo at releiving headache 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). 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. More sumatriptan-treated patients than placebo-treated patients reported adverse events (29% versus 16%) but the difference was not statistically significant. More of these events were mild to moderate in severity, of short duration and resolved without treatment. Sumatriptan had no clinically significant effect on blood pressure, heart rate, electrocardiogram or laboratory test results. It is concluded that oral sumatriptan 100 mg, given as a film-coated, tablet, provides an effective and well-tolerated acute treatment for migraine.

In the present study, 23 patients with migraine without aura were monitored during a migraine attack. Plasma levels of interleukin (IL)-4, IL-5, IL-10, and interferon-gamma were measured by enzyme-linked immunosorbent assay techniques. Interestingly, we observed low to undetectable IL-5 and IL-4 levels, whereas high IL-10 levels were seen in 52.2% of the patients. Interferon-gamma plasma levels were undetectable in all patients. After treatment with sumatriptan, 10 patients showed a subsequent decrease in IL-10 and an increase in both IL-4 and IL-5 plasma levels. Although these findings are derived from a limited number of patients, the apparent return to the IL-4 and IL-5 cytokine profile observed during the interictal period leads us to speculate that a preferential enhancement of TH2-type cytokine production may contribute to the pathogenesis of migraine.

Aim of this study is to evaluate if migraine, daily chronic headache and fibromyalgia in the same patient can be considered as an evolutive continuum of non organic chronic pain. Therefore, migraine, daily chronic headache and fibromyalgia should be considered the expression of chronic antinociceptive system alteration.

The authors, in order to evaluate the important role of gastrointestinal dysfunction during the migraine attack, have studied 53 patients with migraine without aura during the asymptomatic stage between attacks. Patients were examined functionally with a pH meter test of the gastroesophageal tract over 24 hours and morphologically with esophagogastroduodenoscopy. The results of this study point out that in a high percentage of patients with migraine, both evaluations are normal. The authors suggest the possibility of detecting, even hypothetically, an alteration of the common neurotransmitter substrate in the origin of migraine attacks and accompanying symptoms.

The authors describe three patients with episodic cluster headache whose attacks were all treated with subcutaneous sumatriptan. The patients described had a high frequency of attacks (more than two per day); therefore, far higher dosage of the drug was taken than commonly used in cluster headache. The patients did not experience any particular side effects, neither during the treatment period nor on abrupt withdrawal of the drug. Moreover, neither tachyphylaxis nor addiction were observed. The authors point out both the efficacy of sumatriptan, confirmed in all the treated attacks, and its safety even at higher dosages than recommended.

Migraine with aura and migraine without aura may be different clinical expressions of one disease. This theory is debated, however. In order to further address the issue, we administered a standardized questionnaire to 45 migraineurs. The results indicate a significant overlap between migraine with and without aura, most importantly with respect to response to therapy; 70% of patients had similar responses.

Thirty-two patients suffering from migraine without aura were assessed during in interictal period to evaluate the contribution of cytokines to the pathophysiology of migraine. To this end, plasma levels of IFN-gamma, IL-4, IL-5, and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA) techniques. Plasma levels of both IFN-gamma and IL-10 were not increased in the patients and did not differ significantly from healthy controls. Of interest, we observed a strong increase of IL-5 levels in 84.3% as well as increased IL-4 levels in 37.5% of patients with migraine without aura. These results suggests a preferential enhancement of some Th2-type cytokines, and may support the growing arguments of an immunoallergic mechanism in the pathophysiology of migraine.
