12 item Allodynia Symptom Checklist/Brasil: cross-cultural adaptation, internal consistency and reproducibility

Since there was no Portuguese questionnaire to evaluate cutaneous allodynia, which has been pointed out as a risk factor of migraine, we aimed to perform the cross-cultural adaptation of the 12 item Allodynia Symptom Checklist for the Brazilian population and to test its measurement properties. It consisted in six stages: translation, synthesis, back translation, revision by a specialist committee, pretest and submission the documents to the committee. In the pretest stage, the questionnaire was applied to 30 migraineurs of both sexes, who had some difficulty in understanding it. Thus, a second version was applied to 30 additional subjects, with no difficulties being reported. The mean filling out time was 3'36", and the internal consistency was 0.76. To test reproducibility, 15 other subjects filled out the questionnaire at two different times, it was classified as moderate (weighted kappa=0.58). We made available to Brazilian population an easy, quick and reliable questionnaire.Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Apoio ao Ensino, Pesquisa e Assistencia of HCFMRP (FAEPA)Fundacao de Apoio ao Ensino, Pesquisa e Assistencia of HCFMRP (FAEPA

In this article, a group of experts in headache management of the Brazilian Headache Society developed through a consensus strategic measurements to treat a migraine attack in both the child and the adult. Particular emphasis was laid on the treatment of migraine in women, including at pregnancy, lactation and perimenstrual period743262271Neste artigo um grupo de especialistas no tratamento de cefaleia da Sociedade Brasileira de Cefaleia através de um consenso elaborou medidas estratérgicas para tratar uma crise de migrânea tanto na criança como no adulto. Uma enfase particular foi dada no tratamento da migranea na mulher, incluindo gravidez, lactação e período perimenstrua

Behaviour of blood pressure and heart rate during migraine headache.

Objetivos: Avaliar o comportamento da pressão arterial (PA) e da frequência cardíaca (FC) durante a fase de dor da migrânea em pacientes sem hipertensão arterial sistêmica (HAS). Avaliar essas variáveis em função da intensidade de dor e se elas sofrem influência do uso agudo de ibuprofeno. Métodos: Dez pacientes (nove mulheres), entre 21 e 43 anos, com diagnóstico de migrânea foram selecionados. Todos tinham diagnóstico de migrânea sem aura e quatro deles também tinha diagnóstico de migrânea com aura. Eles apresentavam de 3 a 11 dias de dor por mês, não tinham qualquer outro problema de saúde e não estavam em tratamento profilático para migrânea. Além disso, não utilizavam medicamentos que pudessem interferir na PA ou FC. Os pacientes foram submetidos à anamnese e exame físico. Para descartar HAS, foram submetidos a medições convencionais da PA e Medidas Ambulatoriais da Pressão Arterial por 24h. A aquisição das medidas de PA e FC nos períodos livres de dor (interictal) foram realizadas por meio de Medidas Residenciais da Pressão Arterial (MRPA) por quatro a cinco dias consecutivos, com a obtenção de seis medidas ao dia. Para a aquisição das medidas de PA e FC no período de dor da migrânea (ictal), os pacientes foram orientados a fazer MRPA a cada 10 minutos nas duas primeiras horas de dor e, após, a cada 15 minutos até o final da crise. Ainda, deveriam assinalar em um tipo de diário de cefaleia as características da dor a cada hora. Permitiu-se o uso de 400mg de ibuprofeno como tratamento de resgate após o final da segunda hora de dor. Para análise estatística, comparamos os valores de pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), pressão arterial média (PAM) e FC realizadas no período interictal com as realizadas no período ictal. As variáveis obtidas durante a cefaleia foram comparadas em função da intensidade de dor e em função do uso de ibuprofeno. Resultados: As médias de PAS, PAD, PAM do período ictal foram significativamente menores que as do período interictal (p0,01). Comparando as médias dos valores de PAS, PAD, PAM e FC do período interictal com as do período ictal divididas por hora para as primeiras quatro horas de dor, observamos que houve uma redução progressiva dos valores de PAS, PAD e PAM durante todo esse período (p0,01). Quanto à FC, observamos que houve aumento de seus valores na primeira hora de dor (p0,02). Houve uma tendência de redução dos valores das médias de PAS, PAD e PAM nas dores de moderada e forte intensidade. Com relação ao ibuprofeno, não notamos diferenças nas variáveis. Conclusões: Durante a fase de dor da migrânea ocorre uma redução da PA desde a primeira hora de dor. Por outro lado, há um aumento dos valores da FC apenas na primeira hora de dor. Houve uma tendência de que os valores de PA reduzissem à medida que a dor progredisse de leve para moderada e forte intensidades. O uso de 400mg de ibuprofeno não promoveu alterações nas variáveis analisadas.Objectives: To analyse the behavior of blood pressure (BP) and heart rate (HR) during migraine headache in patients without hypertension (HBP). To assess the values of BP and HR according to the intensity of pain, and to check if those variable are influenced by 400 mg of ibuprofen. Methods: Ten patients (nine women), 21 to 43 years-old, with migraine diagnosis were select. All of them had migraine without aura and four of them also had migraine with aura. They had from 3 to 11 days of headache a month, no other healthy problem, and werent on migraine prophylactic treatment. Also, they werent using other drugs that could interfere on BP and HR. Patients were submitted to anamnesis and physical examination. Hypertension was ruled out through office and ambulatory BP measurements for 24 hours. To obtain the values of pain-free period, BP and HR were measured through home measurements which were done from 4 to 5 consecutives days, 6 times a day. To obtain the values of migraine headache period, patients were asked to measure their BP and HR from the beginning to the end of the attack. During the first two hour of pain, they should do the measures each 10 minutes, and after that each 15 minutes until the end of the attack. During the last procedure, patients should write in a kind of headache diary their headache characteristics each hour. Using of 400 mg of ibuprofen was just allowed at the end of the second hour of pain. To statistical analysis, the values of systolic (SBP), diastolic DBP), mean (MBP) blood pressure and HR from pain-free period were compared with the values of these variables from headache period. The values of these variables from headache period were also compared according the intensity of pain and the intake of ibuprofen. Results: The mean values of SBP, DBP and MBP from headache period were statistically lower than those from pain-free period (p0,01). Comparing mean values of SBP, DBP, MBP and HR from pain-free period to means from the headache period, separated by hour, for the first 4 hours of pain, we verified there were a progressive reduction of SBP, DBP, MBP during this phase (p0,01). About the HR, we noticed its values raised during the first hour of pain (p0,02). There was a trend of SBP, DBP and MBP values to be lower during moderate and severe pain. Regarding the use of ibuprofen, we didnt notice differences on BP or HR values. Conclusions: During migraine headache, BP values are lower since the first hour of pain. On the other hand, HR values were different just in the first hour of pain where they were higher. There was a trend of BP lowering as the pain progressed from mild to moderate and severe intensity. Ibuprofen (400 mg) didn\'t change the variables values

Chronic Pain and Depression in the Quality of Life of Women With Migraine - A Controlled Study

Background. Migraine is comorbid to depression and widespread chronic pain (WCP), but the influence of these conditions on the health-related quality of life (HRQoL) of individuals with episodic (EM) and chronic migraine (CM) is poorly understood. Objective.-To assess the prevalence of depressive symptoms and WCP in individuals with EM and CM, as well as to estimate the joint impact of these conditions on the HRQoL of these individuals. Methods.-All women aged 18 to 65 years with a first diagnosis of EM or CM from September of 2006 to September of 2008 seen in an outpatient headache service were invited to participate. They were asked to attend a separate appointment in the service, and to bring another woman of similar age that also agreed to participate. Depressive symptoms were assessed using the Beck Depression Inventory. Questions about WCP followed the protocol of the American College of Rheumatology. HRQoL was assessed using the Short-Form 36 (SF-36). Multivariate analysis modeled HRQoL as a function of headache status, depressive symptoms, and pain, using quantile regression. Results.-Sample consisted of 179 women, 53 in the EM group, 37 in the CM group and 89 in control group. Groups did not differ by demographics. Mean scores of SF-36 were 53.6 (standard deviation [SD] = 23.5) for EM, 44.2 (SD = 18.5) for CM and 61.8 (SD = 21.5) for controls. In multivariate analysis, SF-36 scores were predicted by a CM status (P =.02; -10.05 [95% CI -18.52; -1.58]) and by a Beck Depression Inventory score (P <.01; -1.27 [95% CI -1.55; -0.99]). The influence of WCP in the SF-36 scores approached significance (P =.08; -0.78 [95% CI -1.64; 0.88]). Age did not contribute to the model. Conclusion.-Women with migraine are at an increased chance of WCP, and the chance increases as a function of headache frequency. Both depressive symptoms and CM independently predict HRQoL status.State of Sao Paulo Research Foundation - FAPESP [2008/01248-8]State of Sao Paulo Research Foundation (FAPESP

Interictal Photophobia and Phonophobia Are Related to the Presence of Aura and High Frequency of Attacks in Patients with Migraine

Background: Despite that photophobia and phonophobia are well-known symptoms related to migraine, it is unclear whether they affect daily life activities during the headache-free period. Objective: To evaluate the interictal photophobia/phonophobia intensity during daily activities in migraineurs and non-headache individuals. Methods: Women with migraine without aura (MoA, n = 30), migraine with aura (MA, n = 30), chronic migraine (CM, n = 30) and without headache (CG, n = 30) reported the photophobia and phonophobia intensity during daily activities using a Likert scale ranging from 0 (no discomfort) to 10 (maximum discomfort). Results: The migraine groups reported higher intensity of interictal photophobia and phonophobia than CG during “driving” and “social situations”, respectively (p < 0.05). MA and CM groups presented higher intensity of phonophobia than CG, hearing sounds in everyday situations and listening to conversations in noisy places (p < 0.05). Also, the MA group presented higher interictal phonophobia than the CG to keep concentration in noisy places (p < 0.05). Weak positive correlations were observed between the intensity of both photophobia and phonophobia with migraine intensity, frequency of migraine and frequency of aura (p < 0.05). Conclusion: Interictally, the intensity of photophobia and phonophobia reported during daily activities is higher in patients with migraine, especially those with aura and chronic migraine, than in non-headache subjects

Interaction among nitric oxide (NO)-related genes in migraine susceptibility

The pathogenic mechanisms involved in migraine are complex and not completely clarified. Because there is evidence for the involvement of nitric oxide (NO) in migraine pathophysiology, candidate gene approaches focusing on genes affecting the endothelial function have been studied including the genes encoding endothelial NO synthase (eNOS), inducible NO synthase (iNOS), and vascular endothelial growth factor (VEGF). However, investigations on gene–gene interactions are warranted to better elucidate the genetic basis of migraine. This study aimed at characterizing interactions among nine clinically relevant polymorphisms in eNOS (T−786C/rs2070744, the 27 bp VNTR in intron 4, the Glu298Asp/rs1799983, and two additional tagSNPs rs3918226 and rs743506), iNOS (C−1026A/rs2779249 and G2087A/rs2297518), and VEGF (C−2578A/rs699947 and G−634C/rs2010963) in migraine patients and control group. Genotypes were determined by real-time polymerase chain reaction using the Taqman® allele discrimination assays or PCR and fragment separation by electrophoresis in 99 healthy women without migraine (control group) and in 150 women with migraine divided into two groups: 107 with migraine without aura and 43 with aura. The multifactor dimensionality reduction method was used to detect and characterize gene–gene interactions. We found a significant interaction between eNOS rs743506 and iNOS 2087G/A polymorphisms in migraine patients compared to control group (P < 0.05), suggesting that this combination affect the susceptibility to migraine. Further studies are needed to determine the molecular mechanisms explaining this interaction370183189CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPnão temnão temnão te
