Introduction: Headaches are considered an important public health problem and are estimated to be the second most common pain complaint, with migraines being one of the most common. Migraine treatment is symptomatic and prophylactic to reduce symptoms when an attack starts and prevent new ones from forming, highlighting the importance of adopting healthy habits and a balanced diet. Objective: The purpose of this study was to carry out an integrative review of the literature in order to highlight the main findings on the influence of eating habits and the importance of nutrition for migraine patients. Methodology:A survey study was performed in the following databases: Virtual Health Library (VHL); Medline, LILACS, SciELO, and Google Scholar, in addition to considering the reference list of the consulted works. The PECO P (population) E (exposure) C (comparison) O (outcome) strategy was used, which generated the guiding question of the study: 'How important is food and nutrition for people with chronic migraines?'. Results:A total of 15 studies were selected to analyze in this work and a descriptive synthesis of the results was performed on the relationship and influence of eating habits of people with chronic migraines. Conclusions:It was concluded that eating habits and adequate nutrition have great influence and importance for migraine patients, as they are one of the main culprits of triggering and intensifying attacks (AU).

RESUMO

OBJECTIVE: To assess the incidence, characteristics, and risk factors for developing persistent headache attributed to past ischemic stroke. BACKGROUND: Although the most recent International Classification of Headache Disorders has recognized the existence of persistent headache attributed to past ischemic stroke, there has been limited research in this area. METHODS: This was a prospective cohort study. We initially assessed patients hospitalized with ischemic stroke admitted within 72 h of symptom onset. All patients underwent diffusion-weighted magnetic resonance imaging. These patients were re-interviewed by telephone 1 year after the stroke. Semi-structured questionnaires, the National Institutes of Health Stroke Scale (NIHSS), and six-item Headache Impact Test were used. RESULTS: A total of 119 participants answered the interview conducted 1 year after the stroke. The mean (standard deviation) age was 64 (13.1) years, 82/119 (68.9%) were female, and the median (interquartile range) NIHSS score was 2 (1.0-4.0). The incidence rate of persistent headache attributed to past ischemic stroke was 12/119 (10.1%; 95% confidence interval [CI] 5.3-17.0%). The most frequent pattern presented was a migraine-like pattern in seven of the 12 (58.3%) patients, which had a substantial/severe impact on five of the 12 (41.7%). For most patients this headache continued, although it began to improve. Previous migraine (odds ratio 7.1, 95% CI 1.06-50.0; p = 0.043) and headache intensity in the acute phase of stroke (odds ratio 1.75, 95% CI 1.13-2.7; p = 0.012) were associated with the occurrence of persistent headache attributed to past ischemic stroke. CONCLUSION: Persistent headache attributed to past ischemic stroke is a frequent complication after stroke. It often has a significant impact on patients' lives and presents a migraine-like pattern as its most frequent phenotype.

RESUMO

Abstract Background Increased intracranial pressure (ICP) consists of a set of signs and symptoms related to changes in intracranial compliance (ICC) and ICP. Objective This study presents a retrospective analysis of patients who underwent non-invasive monitoring of ICC based on complaints of headache, correlating decreased brain compliance and increased intracranial pressure. Methods Noninvasive ICC monitoring was performed using a Brain4care device, which contains a strain gauge and a recorder connected to a mechanical device that touches the scalp surface in the frontoparietal area lateral to the sagittal suture. This tool monitors the ICP by identifying small changes in skull measurements that are caused by pressure variations, i.e., skull deformation is associated with the detection of changes in mean ICP. A clinical evaluation of 32 patients with complaints of headache occurred from the analysis of their medical records. Results Of the 32 patients initially chosen, it was possible to complete the analysis of 18 due to the availability of data in the medical records. From the non-invasive monitoring of the ICC, the following data were collected: time-to-peak, P2/P1 ratio, age, and gender. From the statistical analysis of age and P2/P1 ratio, it was noted that as age increases, ICC tends to decrease regardless of sex (p < 0.05). Conclusion This study concluded that there is a correlation between changes in intracranial compliance and headache complaints in outpatients. There was also a relationship between age and decreased intracranial compliance but without a specific pain pattern.

Resumo Antecedentes O aumento da pressão intracraniana (PIC) consiste em um conjunto de sinais e sintomas relacionados a mudanças na complacência intracraniana (CIC) e na PIC. Objetivo Este estudo apresenta uma análise retrospectiva de pacientes que foram submetidos ao monitoramento não invasivo da CIC com base em queixas de cefaleia, correlacionando a diminuição da complacência cerebral e o aumento da pressão intracraniana. Métodos O monitoramento não invasivo da CIC foi realizado utilizando um dispositivo Brain4Care, que contém um medidor de tensão e um gravador conectado a um dispositivo mecânico que toca a superfície do couro cabeludo na área frontoparietal lateral à sutura sagital. Esta ferramenta monitora a PIC identificando pequenas alterações nas medidas do crânio que são causadas por variações de pressão, ou seja, a deformação do crânio está associada à detecção de alterações na PIC média. Uma avaliação clínica de 32 pacientes com queixas de cefaleia ocorreu a partir da análise de seus prontuários médicos. Resultados Dos 32 pacientes inicialmente escolhidos, foi possível concluir a análise de 18 devido à disponibilidade de dados nos prontuários médicos. A partir do monitoramento não invasivo da CIC, foram coletados os seguintes dados: time-to-peak, relação P2/P1, idade e sexo. Da análise estatística de idade e relação P2/P1, observou-se que à medida em que a idade aumenta, a CIC tende a diminuir independentemente do sexo (p < 0,05). Conclusão Este estudo concluiu que existe uma correlação entre as mudanças na CIC e a queixa de cefaleia em pacientes ambulatoriais. Houve também uma relação entre idade e diminuição da CIC, mas sem um padrão de dor específico.

RESUMO

(1) Background: Chronic migraine is a debilitating neurological condition affecting millions worldwide. This study delves into the facial point-of-care (POC) thermographic patterns of women with chronic migraine, aiming to shed light on the condition's pathophysiology and diagnostic potential. (2) Methods: Using infrared POC thermography, the facial temperature distribution of 24 female participants with chronic migraine were analyzed. (3) Results: The findings revealed significant temperature asymmetry in women with right-sided unilateral headaches, particularly in the right frontal and temporal regions. Notably, individuals with bilateral pain did not exhibit thermal pattern differences, suggesting potential diagnostic complexities. While these results offer valuable insights, further research with larger samples is warranted (4) Conclusions: Facial thermography holds promise as an adjunctive tool for migraine diagnosis and understanding its neurophysiological basis; however, cautious interpretation is advised, given the need for validation and expanded investigations. Improved diagnostic criteria and treatment strategies may emerge from this ongoing exploration, ultimately enhancing the quality of life of chronic migraine sufferers.

RESUMO

This narrative review explores the intricate relationship between migraines and art, tracing historical examples and contemporary interpretations of how migraines, especially those with a visual aura, have influenced artists. Highlights how migraines may have shaped artistic inspiration, delving into notable, questionably migraine-infected figures such as Hildegard of Bingen, Giorgio de Chirico, Pablo Picasso, and Salvador Dali, examining how their experiences may have influenced their works. Furthermore, it addresses the emergence of 'migraine art' sponsored by the pharmaceutical industry, presenting the intersection between art, neuroscience, and public engagement. The diagnostic complexity and differentiation of migraines from epilepsy are also discussed, with a special focus on the symptoms of the visual aura and how this has been portrayed through various artistic representations, thus inviting further exploration of the relationship between neurological conditions and creative expression.

Esta revisão narrativa explora a intrincada relação entre enxaquecas e arte, traçando exemplos históricos e interpretações contemporâneas de como as enxaquecas, especialmente aquelas com aura visual, influenciaram os artistas. Destaca como as enxaquecas podem ter moldado a inspiração artística, investigando figuras notáveis e questionavelmente infectadas pela enxaqueca, como Hildegard de Bingen, Giorgio de Chirico, Pablo Picasso e Salvador Dali, examinando como suas experiências podem ter influenciado suas obras. Além disso, aborda o surgimento da "arte da enxaqueca" patrocinada pela indústria farmacêutica, apresentando a intersecção entre arte, neurociência e envolvimento público. A complexidade diagnóstica e a diferenciação entre enxaquecas e epilepsia também são discutidas, com especial foco nos sintomas da aura visual e como esta tem sido retratada através de diversas representações artísticas, convidando assim a uma maior exploração da relação entre condições neurológicas e expressão criativa.

RESUMO

Abstract Migraine is one of the most prevalent and disabling diseases in the world. Migraine attack treatments and prophylactic treatments of this disease are essential to lessen its individual, social, and economic impact. This is a narrative review of the main drugs used for treating migraine, as well as the experimental models and the theoretical frameworks that led to their development. Ergot derivatives, triptans, non-steroid anti-inflammatory drugs, tricyclic antidepressants, beta-blockers, flunarizine, valproic acid, topiramate, onabotulinumtoxin A, ditans, monoclonal antibodies against CGRP and its receptor, and gepants are discussed. Possible therapeutic targets for the development of new drugs that are under development are also addressed. Many of the drugs currently in use for treating migraine were developed for the treatment of other diseases, but have proven effective for the treatment of migraine, expanding knowledge about the disease. With a better understanding of the pathophysiology of migraine, new drugs have been and continue to be developed specifically for the treatment of this disease.

Resumo A migrânea é uma das doenças mais prevalentes e incapacitantes do mundo. O tratamento da crise de migrânea e o tratamento profilático da doença são essenciais para diminuir o seu impacto individual, social e econômico. Este é um artigo de revisão narrativa. Revisamos as principais drogas usadas para a migrânea e os modelos experimentais e referenciais teóricos que levaram ao seu desenvolvimento. Foram abordados os derivados do ergot, triptanas, anti-inflamatórios não hormonais, antidepressivos tricíclicos, betabloqueadores, flunarizina, ácido valproico, topiramato, toxina onabotulínica do tipo A, os ditans, anticorpos monoclonais contra o CGRP e seu receptor e os gepants. Também foram abordados possíveis alvos terapêuticos para o desenvolvimento de novas drogas e drogas que estão em desenvolvimento para o tratamento da migrânea. Muitas das drogas usadas atualmente foram desenvolvidas para o tratamento de outras doenças e se mostraram efetivas para o tratamento da migrânea. Essas ajudaram a ampliar o conhecimento sobre a doença. Com o melhor entendimento da fisiopatologia da migrânea, novas drogas foram e estão sendo desenvolvidas especificamente para o tratamento dessa doença.

RESUMO

Introduction: An association between weight status and migraine has been previously reported; however, this relationship has only been studied in adults, not in the paediatric population. Objective: To evaluate the association between weight status and migraine in the paediatric population. Methods: We searched PubMed/Medline, Scopus, Web of Science, Ovid Medline, and Embase using a cut-off date of May 2023. We included observational studies that evaluated the association between weight status (underweight, overweight, obese, and excess weight) and migraine in the paediatric population (children and adolescents). Normal weight was the comparator. The outcome was migraine (all types, episodic and chronic). We performed meta-analyses using a random-effects model to estimate the pooled effects for each outcome. Sensitivity analysis was performed based on study design and risk of bias (using the Newcastle-Ottawa Scale). Certainty of evidence was assessed using the GRADE approach. Results: Eight studies (6 cross-sectional, 1 case-control and 1 cohort) covering 16,556 patients were included. The overall certainty of evidence was very low for the association between overweight, obesity, and excess weight with migraine. In the sensitivity analysis, meta-analyses of studies with a low risk of bias found that the overweight population probably had an increased odds of migraine (OR: 1.70; 95% CI: 1.14 to 2.53; I2 = 32.3%, p = 0.224) and that excess weight may increase the odds of migraine (OR: 1.58; 95% CI: 1.06 to 2.35; I2 = 83.7%, p = 0.002). Additionally, cohort and case-control studies found that obesity probably increases the odds of migraine. No studies analysed the association between underweight and migraine. Conclusion: The associations between overweight, obesity, excess weight and migraine were uncertain, but studies with better methodological quality reported increased odds. Future longitudinal studies with proper confounding control are needed to disentangle their causal relationship. Systematic review registration: PROSPERO, identifier CRD42021271533.

RESUMO

Abstract Background Genetic variants play a pathophysiological role in headaches, especially in migraine. The Mennonite group (MG) has been geographically and genetically isolated throughout its history, harboring a distinctive distribution of diseases. Objective To determine the characteristics of headaches in a group with direct Mennonite ancestry contrasting with other urban community members (control group [CG]). Methods Subjects with headaches were asked to complete a questionnaire covering: the type of headache, presence of aura, frequency and duration of attacks, pain location and severity, analgesic consumption, premonitory and postdromic manifestations, Depressive Thoughts Scale, Epworth Sleepiness Scale (ESS), General Anxiety Disorder-7, Patient Health Questionnaire-9 (PHQ-9), Migraine Disability Assessment, and Composite Autonomic System Score. Results We included 103 participants (CG: 45, Mennonite group [MG]: 58). Migraine was the most common headache (CG: 91.1%; MG: 81.0%; p = 0.172), followed by tension-type headache (CG: 8.9%; MG: 15.5%; p = 0.381). Aura was identified by 44.4% and 39.7% in the CG and MG, respectively (p = 0.689). The groups differed only concerning the frequency of retro-orbital pain (CG: 55.6%; MG: 32.8%; p = 0.027), PHQ-9 (CG: median 7, range 0 to 22; MG: median 5, range 0 to 19; p = 0.031) and ESS (CG: median 0, range 0 to 270; MG: median 0, range 0 to 108; p = 0.048) scores. Conclusion There were no major differences in the prevalence and clinical characterization of headaches between the MG and the CG. However, the latter showed more diffuse pain, sleepiness, and depressive symptoms. Specific genetic or epigenetic variants in Mennonite descendants might account for these differences.

Resumo Antecedentes Variantes genéticas desempenham um papel fisiopatológico nas cefaleias, especialmente na migrânea. O grupo menonita (GM) tem estado geográfica e geneticamente isolado ao longo de sua história, abrigando uma distribuição distinta de doenças. Objetivo Determinar as características das cefaleias em um grupo com ascendência menonita direta, comparando-as com as de outros membros da comunidade urbana (grupo controle [GC]). Métodos Participantes com cefaleia foram convidados a preencher um questionário abrangendo: tipo de cefaleia; presença de aura; frequência e duração dos ataques; localização e gravidade da dor; consumo de analgésicos; manifestações premonitórias e posdrômicas; Escala de Pensamentos Depressivos; Escala de Sonolência de Epworth (ESS); Transtorno de Ansiedade Geral-7 (GAD-7); Questionário de Saúde do Paciente-9 (PHQ-9); Avaliação de Incapacidade da Migrânea (MIDAS) e Escore do Sistema Autônomo Composto (COMPASS-31). Resultados Incluímos 103 participantes (GC: 45, GM: 58). A migrânea foi a cefaleia mais frequente (GC: 91,1%; GM: 81,0%; p = 0,172), seguida pela cefaleia tensional (GC: 8,9%; GM: 15,5%; p = 0,381). Aura foi identificada por 44,4% e 39,7% nos GC e GM, respectivamente (p = 0,689). Os grupos diferiram apenas com relação à frequência de dor retro-orbitária (GC: 55,6%; GM: 32,8%; p = 0,027), PHQ-9 (GC: mediana 7, amplitude 0 a 22; GM: mediana 5, amplitude 0 a 19; p = 0,031) e ESS (GC: mediana 0, amplitude 0 a 270; GM: mediana 0, amplitude 0 a 108; p = 0,048). Conclusão Não houve diferenças significativas na prevalência e caracterização clínica das cefaleias nos GM e GC. Entretanto, o último grupo mostrou mais dor difusa, sonolência e sintomas depressivos. Variantes genéticas ou epigenéticas específicas em descendentes de menonitas podem justificar tais diferenças.

RESUMO

Abstract Background Peripheral nerve block (PNB) is usually performed in patients with migraine who are resistant to treatment with medications. Objective To compare the efficacy of PNB alone and PNB combined with prophylactic medications in migraine patients. Method The data on migraine patients who underwent PNB in our clinic between November 2019 and January 2022 were retrospectively reviewed. Blocks of the greater occipital nerve (GON), lesser occipital nerve (LON) and supraorbital nerve (SON) were performed upon admission and in the second week. Results The study included 116 patients. While 21 out of 39 episodic migraine (EM) patients continued to use prophylactic medications, 18 were followed up with PNB alone. While 49 out of 77 chronic migraine (CM) patients continued to use prophylactic medications, 28 were followed up with PNB alone. Comparison of the admission and second-month data of the patients who only underwent PNB and those who continued the drug treatment together with PNB in both the EM and the CM group showed that the number of days with pain, number of analgesics taken and scores on the Visual Analog Scale (VAS) and the Migraine Disability Assessment (MIDAS) were significantly reduced in both groups (p < 0.01). Comparison of the second-month data of the patients followed up with PNB alone and those followed up with PNB together with prophylactic medications showed that there was no significant difference between the EM and CM patients (p > 0.05). Conclusion Bilateral GON, LON and SON block with lidocaine injection seems to be an effective treatment on its own, without the need for prophylactic medications, in both EM and CM patients during a two-month follow-up.

Resumo Antecedentes O bloqueio de nervos periféricos (BNP) geralmente é realizado em pacientes com migrânea resistentes ao tratamento medicamentoso. Objetivo Comparar a eficácia do BNP isolado e do BNP combinado com medicamentos profiláticos em pacientes com enxaqueca. Método Os dados de pacientes com enxaqueca submetidos a BNP em nossa clínica entre novembro de 2019 e janeiro de 2022 foram revisados retrospectivamente. Bloqueios do nervo occipital maior (NOM), nervo occipital menor (NOM) e nervo supraorbital (NSO) foram realizados na admissão e na segunda semana. Resultados O estudo incluiu 116 pacientes. Enquanto 21 dos 39 pacientes com enxaqueca episódica (EE) continuaram a usar medicamentos profiláticos, 18 foram acompanhados apenas com BNP. Enquanto 49 dos 77 pacientes com enxaqueca crônica (EC) continuaram a usar medicamentos profiláticos, 28 foram acompanhados apenas com BNP. A comparação dos dados de admissão e do segundo mês dos pacientes que fizeram apenas BNP e daqueles que continuaram o tratamento medicamentoso junto com BNP, tanto no grupo EE quanto no grupo EC, mostrou que o número de dias com dor, o número de analgésicos tomados e os escores da Escala Visual Analógica (EVA) e da Avaliação da Incapacidade da Enxaqueca (AIE) foram significativamente reduzidos em ambos os grupos (p < 0,01). A comparação dos dados do segundo mês dos pacientes acompanhados apenas com BNP e aqueles acompanhados com BNP juntamente com medicações profiláticas mostrou que não houve diferença significativa entre os pacientes EE e EC (p > 0,05). Conclusão O bloqueio bilateral de NOM, NOM e NSO com injeção de lidocaína parece ser um tratamento eficaz por si só, sem a necessidade de medicamentos profiláticos, tanto em pacientes EE quanto com EC durante um seguimento de dois meses.

RESUMO

Abstract Background Evaluation and treatment of primary and secondary headaches is a global public health challenge. Recognizing the epidemiological impact of headaches, a group of researchers linked to the Brazilian Headache Society proposed the Brazilian Headache Registry and drew up its initial protocol. Objective Here we describe the methods and preliminary data obtained from the pilot study. Methods This was a multicenter longitudinal observational study conducted between September 2020 and August 2021. Prospective data were collected in three specialist centers for headache care in states in southern and southeastern Brazil. Patients aged 18 years or older who sought care for headache in tertiary centers and who agreed to participate in the study, were considered eligible. Results Sixty-six patients were included in the pilot study: 43 (65%) from Rio Grande do Sul state and 23 (35%) from Minas Gerais state. Overall, 90% were female, and the subjects' mean age was 38.2 ± 11.2 years. Primary headaches accounted for 85.3% of the diagnoses made. Among secondary headaches, medication overuse headache was the most frequent type (7.1%). Conclusions The pilot study showed the feasibility of the research protocol developed for tertiary centers. The Brazilian Headache Registry will form a source of longitudinal data with the aim of contributing to better characterization of the various phenotypes of patients with primary and secondary headaches, and to detailing the use of health resources and identifying predictors of better clinical outcomes.

RESUMO

Background: It is unknown whether the confinement caused by the coronavirus disease 2019 (COVID-19) pandemic may influence migraine triggers. This study aimed to determine the frequency of migraine and their associated factors in medical students at a Peruvian university. The characteristics of migraine episodes and degree of functional disability caused by migraine were also evaluated. Methods: An analytical cross-sectional study was conducted on medical students of a Peruvian university. The suspected migraine was determined with the Migraine Screen Questionnaire. Sociodemographic, confounding, and COVID-19 pandemic-related variables were included as possible associated factors. Poisson regression models were used, and crude and adjusted prevalence ratios with 95% confidence intervals were estimated. Results: The participants comprised 327 students, and 30.3% (n = 99) had suspected migraine. Sex, clustered semesters, having family members with migraine and COVID-19 risk factors, and hours in front of the computer were associated with a higher probability of migraine. However, having more hours of sleep per day was associated with a lower probability. Moreover, most students with migraine had a severe functional disability (41.4%). Conclusions: The high frequency of migraine in medical students could be due to COVID-19-related quarantine. Certain pandemic-related factors increase the probability of having migraine. A high level of disability should promote timely diagnosis and follow-up in affected students.

RESUMO

BACKGROUND: Although patients with migraine show cervical muscle impairments previous studies investigating motor performance have not characterized the sample of patients with migraine according to the presence/absence of neck pain complaints. OBJECTIVE: To verify if there are differences in the clinical and muscular performance of the superficial neck flexors and extensors during Craniocervical Flexion Test in women with migraine, considering the presence or absence of concomitant symptoms of neck pain. METHODS: The cranio-cervical flexion test performance was assessed by its clinical stage test and by the surface electromyographic activity of the sternocleidomastoid, anterior scalene muscles upper trapezius and splenius capitis. It was assessed in 25 women with migraine without neck pain, 25 women with migraine and neck pain, 25 women with chronic neck pain and 25 pain-free control women. RESULTS: Poorer performance of the cervical muscles was found during the execution of the cranio-cervical flexion test, in addition to higher muscle activity, especially in the sternocleidomastoid, splenius capitis, and upper trapezius muscles in the neck pain, migraine without neck pain, and migraine with neck pain groups in comparison with the results obtained for healthy women in the control group. No difference was observed between the groups of women experiencing pain. Analysis of the extensor/flexor muscle electromyographic ratio showed that there was no difference between the groups. CONCLUSION: Poor cervical muscle performance was observed in both women with chronic nonspecific neck pain and women with migraine regardless of the presence of neck pain.

RESUMO

Abstract Background Although several recent studies have attempted to describe the association between psoriasis and migraine, there is little data in this regard. Objective To explore the relationship between migraine and psoriasis. Methods A total of 312 patients with psoriasis and 312 age- and gender-matched controls without psoriasis were recruited in this case-control study. Based on the diagnosis of migraine, they were divided into 4 subgroups: psoriasis with (PM+) and without (PM-) migraine, and control with (CM+) and without migraine (CM-). The subgroups were compared regarding the migraine and psoriasis characteristics. Results The mean (SD) age of patients and controls (139 males, in each group) was 43.2 (13.2) years. Psoriasis patients were significantly more likely to have migraine (OR = 2.789). Migraine with aura was significantly higher in the PM + group than in the CM + group (p = 0.007). The mean PASI score (p = 0.001), frequency of moderate and severe psoriasis (p = 0.048), and frequency of patients with PsA (p < 0.001) were significantly higher in PM + compared to PM-. The risk of migraine substantially increased with increasing psoriasis severity (OR = 2.062, OR = 3.248, and OR = 4.586 for mild, moderate, and severe, respectively), and with the presence of PsA (OR = 2.438 and OR = 12.930 for patients without and with PsA, respectively). Study limitations Observational nature, not including all confounding factors, not addressing a cause-and-effect relationship. Conclusions In comparison with the non-psoriatic control group, psoriasis patients are predisposed to a significantly higher risk of migraine, particularly migraine with aura, psoriasis patients with more severe disease and those with PsA have a markedly higher risk of having migraine, and the migraine headache index is significantly higher in psoriasis patients.

RESUMO

OBJECTIVE: To review the epidemiology, the differential diagnosis, and the clinical and laboratory factors associated with the care management of headaches in patients with systemic lupus erythematosus (SLE). BACKGROUND: SLE is a chronic autoimmune disease and in 12%-95% of patients, the nervous system is involved. Headache is a frequently reported, although nonspecific, symptom that may potentially represent serious underlying diagnoses. Primary headaches may also occur in these patients, thereby causing a negative and significant impact on their quality of life. METHODS: This is a narrative review. A literature review was conducted on the PubMed platform using the following terms: (1) headache and (2) lupus. All articles considered relevant were included. No limitations were imposed for the publication date. RESULTS: Headache is a frequent symptom in patients with SLE. Although its prevalence is similar to the general population, headaches nonetheless tend to have a greater negative impact on these patients. Patients with SLE are more likely to experience headache due to vascular diseases such as cerebral venous sinus thrombosis, stroke, reversible cerebral vasoconstriction syndrome, posterior reversible encephalopathy syndrome, and vasculitis. Aseptic meningitis, neuroinfections, intracranial neoplasms, and intracranial hypertension or hypotension may also be a cause of headache in these patients. Although used in disease activity scores, the concept of lupus headache is controversial. CONCLUSIONS: Headache is a frequent symptom in patients with SLE. An appropriate approach enables the potentially serious conditions, which are the causes of secondary headaches, to be recognized and treated, together with an appropriate diagnosis and treatment of primary headaches.

RESUMO

Abstract Background Migraine underdiagnosis and undertreatment are so widespread, that hence is essential to diagnose migraine sufferers in nonclinical settings. A systematic review of validation studies on migraine diagnostic tools applicable to nonclinical settings can help researchers and practitioners in tool selection decisions. Objective To systematically review and critically assess published validation studies on migraine diagnostic tools for use in nonclinical settings, as well as to describe their diagnostic performance. Methods A multidisciplinary workgroup followed transparent and systematic procedures to collaborate on this work. PubMed, Medline, and Web of Science were searched for studies up to January 17, 2022. The QUADAS-2 was employed to assess methodological quality, and the quality thresholds adopted by the Global Burden Disease study were used to tail signaling questions. Results From 7,214 articles identified, a total of 27 studies examining 19 tools were eligible for inclusion. There has been no high-quality evidence to support any tool for use of migraine diagnosis in nonclinical settings. The diagnostic accuracy of the ID-migraine, structured headache and HARDSHIP questionnaires have been supported by moderate-quality evidence, with sensitivity and specificity above 70%. Of them, the HARDSHIP questionnaire has been the most extensively validated. The remaining 16 tools have provided poor-quality evidence for migraine diagnosis in nonclinical populations. Conclusions Up till now, the HARDSHIP questionnaire is the optimal choice for diagnosing migraine in nonclinical settings, with satisfactory diagnostic accuracy supported by moderate methodological quality. This work reveals the crucial next step, which is further high-quality validation studies in diverse nonclinical population groups.

Resumo Antecedentes O sub-diagnóstico e o subtratamento da enxaqueca são tão difundidos que, portanto, é essencial para diagnosticar os portadores de enxaqueca em ambientes não-clínicos. Uma revisão sistemática dos estudos de validação das ferramentas de diagnóstico da enxaqueca aplicáveis a ambientes não-clínicos pode ajudar os pesquisadores e profissionais nas decisões de seleção de ferramentas. Objetivo Revisar sistematicamente e avaliar criticamente estudos de validação publicados sobre ferramentas de diagnóstico da enxaqueca para uso em ambientes não-clínicos, bem como descrever seu desempenho diagnóstico. Métodos Um grupo de trabalho multidisciplinar seguiu procedimentos transparentes e sistemáticos para colaborar neste trabalho. PubMed, Medline e Web of Science foram pesquisados por estudos até 17 de janeiro de 2022. O QUADAS-2 foi empregado para avaliar a qualidade metodológica, e os limites de qualidade adotados pelo estudo da Global Burden Disease foram usados para responder a questões de sinalização. Resultados De 7.214 artigos identificados, um total de 27 estudos examinando 19 ferramentas foram elegíveis para inclusão. Não houve evidência de alta qualidade para apoiar qualquer ferramenta para o uso de diagnóstico de enxaqueca em ambientes não clínicos. A precisão diagnóstica do ID-Migraine, questionário de dor de cabeça estruturada e questionário HARDSHIP foram apoiados por evidências de qualidade moderada, com sensibilidade e especificidade acima de 70%. Deles, o questionário HARDSHIP foi o mais amplamente validado. As 16 ferramentas restantes forneceram provas de má qualidade para o diagnóstico de enxaqueca em populações não-clínicas. Conclusões Até agora, o questionário HARDSHIP é a escolha ideal para o diagnóstico da enxaqueca em ambientes não-clínicos, com precisão diagnóstica satisfatória apoiada por uma qualidade metodológica moderada. Este trabalho revela o próximo passo crucial, que é a realização de mais estudos de validação de alta qualidade em diversos grupos populacionais não-clínicos.

RESUMO

Abstract Background Despite previous studies indicating a moderate/high incidence of angiography headache (AH), there is still limited data about the risk factors associated with its occurrence. Objective The present study aimed to assess the associations among demographic, clinical, and technical characteristics of cerebral digital subtraction angiography (DSA) and the occurrence of AH. Methods Cross-sectional analytical observational study with a sample comprised of individuals with a recommendation for elective DSA. Clinical interviews were conducted to assess the occurrence of AH, using a standardized questionnaire. Results Among 114 subjects, the mean age was 52.8 (±13.8) years old, 75.4% (86/114) were women, 29.8% (34/114) had a history of migraines, and 10.5% (12/114) had chronic headaches. The overall frequency of AH was 45.6% (52/114). Of those, 88.4% (46/52) underwent 3D angiography, 7.7% (4/52) underwent aortography, and 1.9% (1/52) underwent both procedures. There was a statistically significant association between AH and previous history of migraine (odds ratio [OR]: 4.9; 95% confidence interval [CI] 1.62-14.7; p = 0.005) and 3D angiography (OR 6.62; 95%CI: 2.04-21.5; p = 0.002). Conclusions 3D angiography is strongly associated with the occurrence of AH, which has never been reported before. The association between a previous history of migraine and AH confirms the results of previous studies.

Resumo Antecedentes Apesar de estudos prévios indicarem uma incidência moderada/alta de cefaleia da angiografia (CA), os dados sobre os fatores de risco associados à sua ocorrência ainda são relativamente escassos. Objetivo O presente estudo teve como objetivo avaliar as associações entre as características demográficas, clínicas e técnicas da angiografia cerebral por subtração digital (ACSD) e a ocorrência de CA. Métodos Estudo observacional analítico transversal com uma amostra composta por indivíduos com indicação de ACSD em caráter eletivo. Entrevistas clínicas foram realizadas utilizando um questionário padronizado para acessar a ocorrência de CA. Resultados Entre os 114 indivíduos, a idade média foi de 52,8 (±13,8) anos, 75,4% (86/114) eram mulheres, 29,8% (34/114) tinham histórico de enxaqueca e 10,5% (12/114) tinham cefaleia crônica. A frequência geral de CA foi de 45,6% (52/114). Desses, 88,4% (46/52) foram submetidos à angiografia 3D, 7,7% (4/52), à aortografia e 1,9% (1/52), aos dois procedimentos. Houve associação estatisticamente significativa entre CA e histórico prévio de enxaqueca (odds ratio [OR] 4,9; intervalo de confiança [IC] 95%: 1,62-14,7; p = 0,005) e angiografia 3D (OR 6,62; IC95%: 2,04-21,5; p = 0,002). Conclusões A angiografia 3D está fortemente associada à ocorrência de CA, o que é inédito na literatura. A associação entre um histórico de enxaqueca e a CA confirma os resultados de estudos anteriores.

RESUMO

INTRODUCTION: There is controversy as to whether migraine affects the behavior of ischemic penumbra during the acute phase of an ischemic stroke, thereby accelerating the formation of cerebral infarction. OBJECTIVES: To assess whether migraine modifies the existence and volume of the divergence between the areas of diffusion and perfusion in the stroke (the penumbra) and whether migraine implies a poorer prognosis after the stroke. METHODS: This was a prospective cohort study. We included hospitalized patients with ischemic stroke within 72 h of symptom onset (convenience sampling). A semi-structured questionnaire, the National Institute of Health Stroke Scale, and the modified Rankin Scale (mRS) were used. Patients underwent magnetic resonance imaging (MRI) of the brain with diffusion and with perfusion. Patients were assessed by telephone 3 months after the stroke to determine the prognosis. Scores of > 2 on the mRS were considered to have a poor prognosis. RESULTS: A total of 221 patients were included, 131/221 (59%) of whom were male, and with a mean (SD) age of 68.2 (13.8) years. Ischemic penumbra analysis was performed in 118 patients. There was no association between migraine and the absence of ischemic penumbra (16/63 [25%] vs. 12/55 [22%]; odds ratio 1.22, 95% confidence interval 0.52-2.87; p = 0.64). There was no difference in stroke volume between those with and without migraine (median [interquartile range] 1.0 [0.4-7.9] vs. 1.8 [0.3-9.4] cm3 ; p = 0.99). Migraine was not associated with the stroke prognosis after multivariable analysis. CONCLUSION: Migraine is not associated with the absence of ischemic penumbra, the volume of the ischemic penumbra, or the stroke prognosis.

RESUMO

Abstract Background Due to coronavirus disease 2019 (COVID-19) pandemic response measures, the administration of botulinum toxin (BTX) was delayed for many patients during the first lockdown period in Portugal. Objectives To review the impact of postponing BTX treatment on migraine control. Methods This was a retrospective, single-center study. Patients with chronic migraine who had done at least three previous BTX cycles and were considered responders were included. The patients were divided into two groups, one that has had their treatment delayed (group P), and one that has not (controls). The Phase III Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) protocol was used. Migraine-related data were obtained at baseline and at three subsequent visits. Results The present study included two groups, group P (n = 30; 47.0 ± 14.5 years; 27 females, interval baseline -1st visit: 5.5 [4.1-5.8] months) and the control group (n = 6; 57.7 ± 13.2 years; 6 females; interval baseline-1st visit 3.0 [3.0-3.2] months). No difference between the groups was present at baseline. When compared to baseline, the number of days/month with migraine (5 [3-6.2] vs. 8 [6-15] p < 0.001), days using triptans/month (2.5 [0-6] vs. 3 [0-8], p = 0.027) and intensity of pain (7 [5.8-10] vs. 9 [7-10], p = 0.012) were greater in the first visit for group P, while controls did not present a significant variation. The worsening of migraine-related indicators decreased in the following visits; however, even in the third visit, it had not returned to baseline. Correlations were significant between the delayed time to treatment and the increase in days/month with migraines at the first visit after lockdown (r = 0.507; p = 0.004). Conclusions There was a deterioration of migraine control after postponed treatments, with a direct correlation between the worsening of symptoms and the number of months that the treatment was delayed.

Resumo Antecedentes Devido às medidas de resposta à pandemia de coronavirus disease 2019 (covid-19), a administração de toxina botulínica (TXB) foi adiada para muitos pacientes durante o primeiro confinamento em Portugal. Objetivos Avaliar o impacto do adiamento do tratamento com TXB no controle da enxaqueca. Métodos Estudo retrospectivo unicêntrico. Foram incluídos pacientes com enxaqueca crônica com pelo menos três ciclos prévios de TXB e que tenham sido considerados respondedores. Os pacientes foram divididos em dois grupos, sendo um com atraso do tratamento (grupo P) e outro sem atraso (controles). O protocolo Phase III Research Evaluating Migraine Prophylaxis Therapy (PREEMPT) foi utilizado. Dados clínicos relacionados com a enxaqueca foram obtidos na consulta inicial (T0) e nas três consultas subsequentes (T1-3). Resultados O presente estudo incluiu dois grupos, o grupo P (n = 30; 47,0 ± 14,5 anos; 27 mulheres, intervalo T0-1ª visita: 5,5 [4,1-5,8] meses) e o grupo controle (n = 6; 57,7 ± 13,2 anos; 6 mulheres; intervalo T0-1ª visita 3,0 [3,0-3,2] meses). Os grupos não apresentavam nenhuma diferença no início do estudo. Quando comparado à T0, o número de dias/mês com enxaqueca (5 [3-6,2] vs. 8 [6-15], p < 0,001), dias usando triptanos/mês (2,5 [0-6] vs. 3 [0-8], p = 0,027) e intensidade da dor (7 [5,8-10] vs. 9 [7-10], p = 0,012) foram maiores na primeira visita no grupo P, não apresentando os controles variação significativa. A piora dos indicadores relacionados com a enxaqueca diminuiu nas visitas seguintes; porém, mesmo na terceira visita, ainda não haviam retornado ao basal. As correlações foram significativas entre o atraso do tratamento e o aumento de dias/mês com enxaqueca na primeira consulta após o confinamento (r = 0,507; p = 0,004). Conclusão Houve piora clínica da enxaqueca após o adiamento do tratamento em correlação direta com a duração do atraso.

RESUMO

BACKGROUND: Although several recent studies have attempted to describe the association between psoriasis and migraine, there is little data in this regard. OBJECTIVE: To explore the relationship between migraine and psoriasis. METHODS: A total of 312 patients with psoriasis and 312 age- and gender-matched controls without psoriasis were recruited in this case-control study. Based on the diagnosis of migraine, they were divided into 4 subgroups: psoriasis with (PM+) and without (PM-) migraine, and control with (CM+) and without migraine (CM-). The subgroups were compared regarding the migraine and psoriasis characteristics. RESULTS: The mean (SD) age of patients and controls (139 males, in each group) was 43.2 (13.2) years. Psoriasis patients were significantly more likely to have migraine (OR = 2.789). Migraine with aura was significantly higher in the PM + group than in the CM + group (p = 0.007). The mean PASI score (p = 0.001), frequency of moderate and severe psoriasis (p = 0.048), and frequency of patients with PsA (p < 0.001) were significantly higher in PM + compared to PM-. The risk of migraine substantially increased with increasing psoriasis severity (OR = 2.062, OR = 3.248, and OR = 4.586 for mild, moderate, and severe, respectively), and with the presence of PsA (OR = 2.438 and OR = 12.930 for patients without and with PsA, respectively). STUDY LIMITATIONS: Observational nature, not including all confounding factors, not addressing a cause-and-effect relationship. CONCLUSIONS: In comparison with the non-psoriatic control group, psoriasis patients are predisposed to a significantly higher risk of migraine, particularly migraine with aura, psoriasis patients with more severe disease and those with PsA have a markedly higher risk of having migraine, and the migraine headache index is significantly higher in psoriasis patients.
