RESUMO

OBJECTIVE: The aim of this study was to assess alcohol use problems in patients with migraine and tension-type headache. METHOD: We evaluated 81 patients with migraine and 62 patients with tension-type headache. The identification of alcohol consumption problems was carried out with Alcohol Use Disorders Identification Test (AUDIT). Alcohol use problem was defined as an AUDIT score of 8 or above. The headache impact was calculated with headache impact test (HIT-6). RESULTS: The proportions of alcohol use problem among patients with migraine and tension-type headache were 5.2% and 16.1%, respectively (P=0.044). The headache impact was significantly higher with migraine than with tension-type headache (P<0.0001). There was an inverse correlation between headache impact and AUDIT (P=0.043). CONCLUSIONS: Our results suggest that migraine patients are less prone to alcohol use problems than tension-type headache patients. One of the possible reasons is that migraine is associated with greater impact than tension-type headache.

Objetivo: Este estudo avaliou o consumo problemático de álcool em pacientes com migrânea e em pacientes com cefaleia do tipo tensional. Método: Foram avaliados 81 pacientes com migrânea e 62 pacientes com cefaleia do tipo tensional. A avaliação do consumo de álcool foi realizada com o Teste para Identificação de Problemas Relacionados ao Uso de Álcool (AUDIT), sendo considerado consumo problemático quando o escore do AUDIT foi igual ou maior que 8. O impacto funcional da cefaleia foi avaliado pelo Teste de Impacto da Cefaleia (HIT-6). Resultados: As proporções de desordens relacionadas ao álcool entre pacientes com migrânea e cefaleia do tipo tensional foram 5,2% e 16,1%, respectivamente (P=0,044). O impacto funcional foi significativamente maior na migrânea que na cefaleia do tipo tensional (P<0,0001). Houve significativa correlação entre comprometimento funcional da cefaleia e os escores do AUDIT (P=0,043). Conclusões: Nossos resultados sugerem que pacientes com migrânea têm menor probabilidade de apresentar consumo problemático do álcool que pacientes com cefaleia do tipo tensional. Uma das possíveis explicações é que o impacto funcional da cefaleia é maior na migrânea que na cefaleia do tipo tensional. .

RESUMO

The aim of this study was to investigate possible association between migraine and physical practice among 480 medical students who were submitted to a questionnaire about headaches and physical practices. Migraine diagnosis was assessed by ID-Migraine and functional disability was evaluated with MIDAS. The type (aerobic or strength training), the weekly frequency and the intensity of physical practice and body mass index (BMI) were assessed. There was a reduction in functional disability of migraine in students reporting physical practice (no physical practice - MIDAS=8.81±1.40, physical practice - MIDAS=15.49±1.78; P=0.03). Frequency, intensity, and type of physical practices were not associated with functional impact of migraine. BMI did not correlate with migraine impact (normal weight - MIDAS=12.34±1.33, overweight or obese - MIDAS=17.45±3.86; P=0.33). These results were confirmed by multivariate analysis. Our data suggest that physical practice is inversely related with functional disability of migraine in university students regardless of BMI.

O objetivo deste estudo foi avaliar a possível associação entre migrânea e a prática de exercícios físicos em uma população de 480 estudantes de medicina. O rastreio de migrânea foi realizado com o inventário ID-migrânea e o comprometimento funcional da migrânea foi estimado com o inventário MIDAS. O tipo (aeróbica ou musculação), frequência e intensidade da atividade física e o índice de massa corpórea (IMC) foram determinados. Houve menor comprometimento funcional da migrânea nos estudantes que referiram praticar exercícios (não praticantes de exercícios - MIDAS=8,81±1,40, praticantes de exercícios - MIDAS=15,49±1,78; P=0,03). A frequência, o tipo e a intensidade dos exercícios não se correlacionaram com o grau de comprometimento funcional da migrânea. Não houve associação entre o IMC e a severidade da migrânea (peso normal - MIDAS=12,34±1,33; sobrepeso ou obesidade - MIDAS=17,45±3,86; P=0,33). Estes resultados foram confirmados por análise multivariada. Portanto, os dados sugerem uma relação inversa entre prática de exercícios físicos e grau de comprometimento funcional da migrânea em estudantes universitários, independentemente do IMC.

RESUMO

OBJECTIVES: This study assessed cardiovascular reactivity to mental stress and cold pressure test in migraineurs and controls. It compared the cardiovascular reactivity between patients with migraine with aura and patients with migraine without aura. BACKGROUND: Several studies have assessed the autonomic nervous system functioning and cardiovascular responses to stressor stimuli in migraine. Cold pressure test and sustained attention tasks are distinct forms of induced stress. It is still unknown if patients with migraine have distinct patterns of response to sustained attention tasks and cold pressure test, since no previous studies have evaluated the cardiovascular responses to these 2 distinct types of stress in the same population of migraine patients. METHODS: Two distinct protocols were used to induce cardiovascular reactivity. Mental stress was induced by using a Stroop test card, a procedure involving the maintenance of the attention control. The other protocol was the cold pressure test. The blood pressure and heart rate were digitally recorded in rest and test phases. The mean elevation and the variance of blood pressure and heart rate were compared between groups. RESULTS: Patients with migraine had higher rest systolic blood pressure and lower heart rate induced by mental stress than controls. There were no differences between migraineurs and controls with cold pressure test. There were no differences between migraineurs with and without aura. CONCLUSION: There was a significantly different pattern of cardiovascular reactivity between migraineurs and controls with mental stress but not with cold pressure test. Distinct central nervous system structures are involved in these 2 types of stress. A distinct pattern of activation of the prefrontal cortex-periaqueductal gray matter circuit in migraine may explain a singular autonomic reactivity to mental stress in this disease.

RESUMO

Few trials have evaluated combination of two or more drugs in the preventive treatment of migraine. In this study three therapeutic regimens were compared: (a) propranolol, at a dose of 40 mg per day, (b) nortriptyline, at a dose of 20 mg per day, and (c) the combination of these two drugs in these dosages. The groups were matched according to age, gender, and frequency of migraine attacks prior to treatment. The period of treatment was two months and the frequency and intensity of headache attacks of the 30 days pre-treatment period were compared with the frequency of headaches in the treatment period. Fourteen patients in groups A and B and sixteen patients in group C have completed the study. Treatment with propranolol, alone or in combination, was shown to be effective. Treatment with nortriptyline alone was not effective. All three therapeutic regimens were safe and side effects were minimal. The frequency of discontinuation of the study was the same in the 3 groups but no patient left the study due to adverse reactions. The combined therapy proved to be as safe as the monotherapy. Further studies evaluating this and other possible combinations of drugs in higher doses and for longer periods, should more clearly elucidate the role of combined therapy in the treatment of migraine.

Poucos ensaios clínicos têm avaliado o tratamento preventivo da migrânea através da combinação de drogas. Neste estudo, três regimes terapêuticos foram comparados: (a) popranolol, na dose de 40 mg por dia, (b) nortriptilina, na dose de 20 mg por dia e (c) combinação destas duas drogas nestas dosagens. Os grupos foram pareados de acordo com idade, sexo e freqüência de crises previamente ao tratamento. O período de tratamento foi de dois meses e a frequência e a intensidade das crises de cefaléia do período pré-tratamento foram comparadas com as do período de tratamento. Concluíram o estudo 14 pacientes do grupo A, 14 do grupo B e 16 do grupo C. Os tratamentos com propranolol, isolado ou em associação mostraram-se eficazes. O tratamento com nortriptilina isolada não se mostrou eficaz para a redução do número de dias com cefaléia. Todos os três regimes terapêuticos foram seguros e os efeitos colaterais foram mínimos. A freqüência de abandono do estudo foi a mesma nos 3 grupos e nenhum paciente abandonou o estudo devido a reações adversas. A terapia combinada mostrou-se tão segura quanto a monoterapia. Estudos futuros avaliando esta e outras possíveis combinações de drogas, em doses maiores e por períodos mais longos, deverão elucidar mais claramente o papel da terapia combinada no tratamento da migrânea.
