Introdução A migrânea afeta 9,1% de crianças e adolescentes e pode ocasionar crises de curta duração, intensidade variável, podendo ser crônica ou episódica. Embora o processo de sensibilização central seja conhecido na migrânea, ainda não está estabelecida a relação entre a alodinia cutânea e as características da crise em crianças e adolescentes.  Objetivo Avaliar a associação da alodinia cutânea com as características da migrânea na população pediátrica. Métodos Este é um estudo piloto, com desenho transversal, que avaliou 17 pacientes com migrânea (12,1 anos, DP 3,2) de ambos os sexos, recrutados no Ambulatório de Cefaleia Infantil do Hospital das Clínicas de Ribeirão Preto. Os pacientes preencheram um questionário estruturado sobre a frequência, intensidade e duração da migrânea, e em seguida responderam ao Questionário de Alodinia baseado no ICHD-III versão beta (adaptado), composto por 4 questões que avaliam a presença ou ausência da alodinia cutânea durante crises de migrânea. Pacientes que apresentaram pelo menos duas respostas positivas foram classificados com alodinia cutânea. O estudo foi aprovado pelo Comitê de Ética em Pesquisa (CAAE 31864020.0.0000.5440). A correlação de Spearman (p<0,05) foi aplicada para avaliar a associação entre as variáveis.  Resultados A alodinia cutânea foi observada em 53% dos pacientes. Todos os participantes apresentaram migrânea episódica (frequência 3,0 dias por mês; DP 2,3), intensidade de dor leve (2,2; DP 0,7) e curta duração (5,4 horas; DP 5,2). Não foram observadas correlações significativas entre a presença de alodinia e a frequência (rho=0,01; p=0,96), intensidade (rho=0,37; p=0,13) e duração (rho= -0,02; p=0,92) das crises de migrânea.  Conclusão Os dados deste estudo piloto sugerem que a alodinia cutânea não está associada com a apresentação clínica da crise migranosa em crianças e adolescentes.

IntroductionMigraine affects 7.7% of children and adolescents and presents with short duration, bilateral and generally frontotemporal localization, however, the relationship of pain and sensitivity symptoms and their correlations with physical tests as well as range of motion are not well understood in these groups. ObjectiveCorrelate sensitization including allodynia and pressure pain threshold (PPT) of cervical muscles with neck mobility in children and adolescents with migraine. MethodsFifty children (CH) and adolescents (AD) diagnosed with migraine by ICHD-III were screened, of both sexes, aged between 6 and 17 years at the tertiary headache outpatient clinic. Allodynia was assessed by the adapted allodynia questionnaire based on the ICHD-III and the sensitivity of the cervical muscles sternocleidomastoid, elevator, suboccipital, trapezius and scalene by the pressure pain threshold (PPT) using a digital algometer DDK-20 Kratos®. The active mobility of the cervical spine (ROM) was evaluated in the movements of flexion, extension, lateral flexion, and rotation by the Flexion Rotation Test (FRT), using the CROM®. ResultsThe mean age of patients was 11.7 years (SD=3.0), most of them female (n=31/62%), adolescents (n= 28/56%) with a diagnosis of episodic migraine (n=32/64%), of low intensity (2.4; SD=0.6), pulsatile quality, duration in hours (18.0; SD=22.7) and more than half of the sample had no aura (n=32/64%). More than 70% of the sample had some comorbidity associated with the diagnosis of migraine, and neurological diseases, such as epilepsy, were more prevalent in both children (25.2%) and adolescents (26.3%), followed by respiratory diseases in children (20.1%) and psychological conditions in adolescents (19.8%).

IntroductionChildhood headache is one of the most common neurological symptoms that affects about 60% of children (CR) and adolescents (AD) and its prevalence increases with age. Primary and secondary childhood headache have different characteristics and prevalence, but also have similarities, such as the diagnostic and treatment method. However, the data available in the literature do not take into account the level of complexity at healthy service where these children and adolescents are treated. ObjectivesTo analyze the clinical characteristics of children (CH) and adolescents (AD) with primary and secondary headaches of tertiary-level headache outpatient clinic. MethodsRetrospective study, based on review of medical records of CH and AD with primary or secondary headaches between the years 2016 and 2021. Sociodemographic data, medical history, clinical history, and daily routine of the child were obtained. The proportion of primary and secondary headaches in the CH and AD groups was also calculated. For continuous variables and categorical data, the chi-square test was used, considering p<0.05. ResultsA total of 386 medical records were included, of which 206 were CH (n=112; 54.8% girls) and 178 AD (n=118; 66.8% girls). Headaches were episodic in CH (57.3%) and chronic in AD (49.7%), [X2(2)=10.001; p=0.007], of mild intensity in CH (64.1%), strong in AD (48.5%), [X2(3)=25.802; p=0.000]. In CH, the mostprevalent type of headache was in pressure (64.3%) and pulsatile in AD (52.8%), [X2(5)=14.595; p=0.012]. (To see the complete abstract, please, check out the PDF).
