Actualización sobre la comorbilidad migraña-depresión / Update on migraine-depression comorbidity

Introducción: La migraña y el trastorno depresivo son patologías altamente prevalentes e incapacitantes, las cuales presentan relaciones bidireccionales de comorbilidad. En la literatura se han descrito factores de riesgo y mecanismos fisiopatológicos comunes para ambas enfermedades, así como asociaciones entre estas y su presentación clínica. Métodos: El presente texto es una revisión narrativa de la literatura. La búsqueda del material bibliográfico se hizo mediante distintas bases de datos especializadas en el área de la salud. Resultados: Algunos factores de riesgo están asociados con ambas patologías, y ambas comparten factores patogénicos, incluidos cambios funcionales, estructurales, genéticos, epigenéticos y hormonales, entre otros. Varios de los tratamientos preventivos que han demostrado eficacia en el tratamiento de la migraña son medicamentos o medidas con efecto antidepresivo. Discusión: Si se consideran las asociaciones y los factores comunes descritos en la literatura, se hace evidente que en el enfoque de pacientes diagnosticados con alguna de estas patologías es necesario tener en cuenta una posible comorbilidad entre migraña y depresión. Conclusión: Es importante promover el tamizaje de estas dos condiciones en pacientes diagnosticados con alguna de ellas, pues esto puede tener implicaciones terapéuticas e impacto en la calidad de vida.

Introduction: Migraine and depressive disorder are highly prevalent and disabling pathologies, which present bidirectional relationships of comorbidity. Common risk factors and pathophysiological mechanisms for both diseases have been described in the literature, as well as associations between them and their clinical presentation. Methods: This text is a narrative literature review. The bibliographical material was found through different databases specialized in health sciences. Results: Some risk factors are associated with both pathologies, and both share pathogenic factors, including functional, structural, genetic, epigenetic, hormonal changes, among others. Several of the preventive treatments that have shown efficacy in the treatment of migraine are medications or measures with an antidepressant effect. Discussion: Considering the associations and common factors described in the literature, it becomes evident that in the approach to patients diagnosed with any of these pathologies, it may be beneficial to consider a possible migraine-depression comorbidity. Conclusion: It is important to promote the screening of these two patients diagnosed with some, since it can have therapeutic implications and impact on quality of life.

Frecuencia de migraña y discapacidad generada en estudiantes de medicina humana de una universidad privada en Lima, Perú / Frequency of migraine and disability generated in medical students at a private university in Lima Peru

Objetivo : Estimar la frecuencia de migraña, y discapacidad generada en estudiantes de medicina de una universidad privada de Lima Metropolitana. Métodos : Estudio transversal en una muestra no probabilística por conveniencia, mediante la aplicación online del autocuestionario ALCOI-95, para evaluar la presencia de migraña, seguido por el cuestionario MIDAS para medir la discapacidad en los positivos al primer cuestionario. El rendimiento académico fue evaluado mediante el promedio ponderado de sus calificaciones. Resultados : Cuarenticinco (21,6%) de 208 estudiantes experimentaron migraña (12,5% con aura y 9,1% sin aura), 14 (33,3%) de los cuales mostraron discapacidad severa y 12 (28,6%) moderada. Los portadores de migraña con aura tuvieron una media menor del promedio ponderado acumulado de sus calificaciones, comparado con aquellos con migraña sin aura. Los factores independientemente asociados a la migraña fueron tener un miembro de la familia nuclear con migraña y problemas para mantener el sueño. Conclusión : Dos de cada 10 estudiantes presentaron migraña y 1/3 de los afectados experimentó discapacidad severa.

SUMMARY Objective: To estimate the frequency of migraine, associated factors and disability generated (including its relationship with academic performance) in medical students at a private university in Metropolitan Lima. Methods: Cross-sectional study in a non-probabilistic convenience sample using the online application of the ALCOI-95 self-questionnaire, to assess the presence of migraine, followed by the MIDAS questionnaire to measure disability in those positive to the first questionnaire. . Results: Fourty-five (21.6%) of 208 students experienced migraine (12.5% with aura and 9.1% without aura), 14 (33.3%) of whom showed severe, and 12 (28.6%) moderate disability. Migraine with aura carriers had a lower mean than the cumulative weighted average of their academic scores. Independent factors associated with migraine were to have a nuclear family member with migraine, and sleep-maintenance problems. Conclusion: Two out of 10 students had migraine, and one third of them had severe disability.

Migraine with aura and stroke - the role of warning signs in the context of secondary headaches: case report / Enxaqueca com aura e acidente vascular cerebral ­ o papel dos sinais de alerta no contexto das cefaleias secundárias: relato de caso

Introduction: Headache is a very common complaint in doctors' offices, with primary causes being the majority in relation to secondary ones. Despite this, the identification of secondary headaches is very relevant in clinical practice, since these can be a life-threatening condition, functionality or even a reversible cause. However, imaging screening for all individuals with headache is costly and unrewarding. Therefore, it is important to know the warning signs that, together with the clinical context, lead to a more precise indication of these exams and early and well-targeted therapeutic interventions. Clinical case: This is a 60-year-old man, previously dyslipidemic and smoker, with migraine with aura reported since childhood, who underwent treatment with sodium valproate, with headache attack suppression. About 4 months before admission, he presented with an alteration in the pain pattern, amaurosis fugax in the right eye, dizziness and mild paresis and hypoesthesia in the left side of the body, primarily treated by him as migraine crises, without improvement with the use of triptans. A new outpatient investigation was carried out, which showed multiple small infarcts in the right hemisphere secondary to atheromatous plaque in the right carotid bulb with an obstruction of approximately 85%. Diagnostic and therapeutic arteriography was performed, with stent implantation, uneventfully. Conclusion: The differential diagnosis between migraine with aura and a cerebrovascular event has already been widely reported in the literature and constitutes a pitfall in the routine of headaches, since a serious and potentially disabling condition can be overlooked. The joint evaluation of the alarm signs with the global context becomes an important tool in the propaedeutics of these patients, with knowledge of this casuistry being something relevant within clinical practice.

Introdução: A cefaleia é uma queixa muito comum nos consultórios médicos, sendo as causas primárias majoritárias em relação às secundárias. Apesar disso, a identificação de cefaleias secundárias é muito relevante na prática clínica, uma vez que estas podem ser uma condição potencialmente fatal, funcional ou mesmo uma causa reversível. No entanto, o rastreio imagiológico para todos os indivíduos com cefaleias é dispendioso e pouco recompensador. Portanto, é importante conhecer os sinais de alerta que, juntamente com o contexto clínico, levam a uma indicação mais precisa destes exames e a intervenções terapêuticas precoces e bem direcionadas. Caso clínico: Trata-se de um homem de 60 anos, previamente dislipidémico e fumador, com queixa de enxaqueca com aura desde a infância, que realizou tratamento com valproato de sódio, com supressão das crises de cefaleia. Cerca de 4 meses antes da internação apresentou alteração do padrão álgico, amaurose fugaz em olho direito, tontura e leve paresia e hipoestesia no lado esquerdo do corpo, tratada por ele primariamente como crises de enxaqueca, sem melhora com o uso de triptanos. Foi realizada nova investigação ambulatorial que evidenciou múltiplos pequenos infartos no hemisfério direito secundários a placa de ateroma no bulbo carotídeo direito com obstrução de aproximadamente 85%. Foi realizada arteriografia diagnóstica e terapêutica, com implante de stent, sem intercorrências. Conclusão: O diagnóstico diferencial entre enxaqueca com aura e evento cerebrovascular já foi amplamente relatado na literatura e constitui uma armadilha na rotina das cefaleias, uma vez que uma condição grave e potencialmente incapacitante pode ser negligenciada. A avaliação conjunta dos sinais de alarme com o contexto global torna-se uma ferramenta importante na propedêutica destes pacientes, sendo o conhecimento desta casuística algo relevante dentro da prática clínica.

Recomendaciones de la Asociación Colombiana de Neurología para el uso de anticuerpos monoclonales antiCGRP en la profilaxis de migraña / Recommendations on the use of the antiCGRP monoclonal antibodies for migraine prophylaxis on behalf of the Colombian Association of Neurology

RESUMEN INTRODUCCIÓN: El desarrollo de anticuerpos monoclonales (mAbs) contra el péptido relacionado con el gen de la calcitonina (CGRP) ha determinado una nueva era terapéutica en la profilaxis de migraña, demostrando su efectividad en pacientes con migraña episódica (ME) y migraña crónica (MC), con respuesta desde pacientes naïve hasta refractarios a múltiples medicamentos. La disminución del 50% de los ataques de migraña al mes (DMM) durante los primeros 3 meses de uso es el desenlace aproximado en el 50% de los pacientes que reciben esta terapia. OBJETIVO: Este consenso de la Asociación Colombiana de Neurología (ACN) tiene el objetivo de guiar la selección y uso racional de los mAbs antiCGRP en pacientes con ME y MC. MATERIALES Y MÉTODOS: El comité de cefalea de la ACN mediante la aplicación de la metodología Delphi y discusiones en reuniones posteriores desarrolló un documento en formato de consenso soportado en literatura y recomendaciones de expertos. RESULTADOS: Se obtuvieron respuestas de 14 expertos en cefalea sobre moléculas utilizadas en profilaxis de migraña, analizando su aplicabilidad en situaciones clínicas frecuentes. DISCUSIÓN: Los mAbs antiCGRP han demostrado efectividad con adecuado soporte fisiopatológico, considerando que son moléculas de alto precio en una enfermedad de alta prevalencia, existe la necesidad de guíar la selección del paciente que mejor puede beneficiarse de su administración CONCLUSIONES: Los mAbs antiCGRP están recomendados en pacientes con ME y MC que presentan falla terapéutica a otras moléculas profilácticas.

ABSTRACT INTRODUCTION: The development of monoclonal antibodies (mAbs) against Calcitonin Gene Related Peptide (CGRP) has determined a new therapeutic era in migraine prophylaxis, demonstrating its effectiveness in patients with episodic migraine (EM) and chronic migraine (CM), obtaining a response in naive patients and in those who are refractory to multiple medications. A 50% decrease in migraine attacks per month during the first 3 months of use is the approximate outcome in 50% of patients receiving this therapy. OBJECTIVE: This consensus from the Colombian Association of Neurology (ACN) has the objective of serving as a guide for the rational use of antiCGRP mAbs in patients with EM and CM. METHODS AND MATERIALS: The headache committee through the application of the Delphi methodology and discussions in subsequent meetings, develops this consensus, supported in the published literature and expert recommendations. RESULTS: Fourteen answers from headache experts were received regarding the use of drugs for migraine prophylaxis, analyzing their applicability in frequent clinical situations. DISCUSSION: AntiCGRP mAbs have proved their effectiveness with adequate pathophysiological support, but with a high price in a highly prevalent disease, there is then a need to select the patient who best benefits from this therapy. CONCLUSIONS: AntiCGRP mAbs are recommended in patients with EM and CM that have previously failed to other prophylactic drugs.

Migraña crónica sin aura, dolor referido a ATM: informe de caso / Cronic migrain without aura, referall pain in TMJ: Case report

Resumen Muchos pacientes presentan dolores de cabeza primarios que no son tomados en cuenta en la consulta diaria de odontología. Es común que los asocien a un dolor referido a la articulación témporomandibular, inclusive a un dolor dental de origen no odontogénico, donde se ve incluida esta estructura.

Abstract A lot of the patients present primary headaches and most of the time, they are not connected in the general practice of dentistry, it´s common that the patient relates the pain to the symptom of TMJ referral pain, or another dental pain non odontogenic, muscular or others.

Migraña y Riesgo de Enfermedad Cardiovascular / Migraine and risk of cardiovascular disease

Introducción: la migraña se presenta con más frecuencia en personas que presentan factores de riesgo cardiovascular. Objetivo: mediante esta revisión bibliográfica narrativa se busca actualizar el conocimiento acerca de la relación existente entre migraña y el riesgo de enfermedad cardiovascular para mejorar la evaluación clínica de estos pacientes. Métodos: se realizó una búsqueda bibliográfica electrónica en Pubmed, Science Direct, Cochrane, Trip Medical Database, New England Journal of Medicine, Elsevier, sobre migraña y riesgo cardiovascular para obtener información con la mejor calidad de evidencia posible. Resultados: se recopilaron 68 artículos, de los cuales se eligieron 33 que cumplieron con los criterios de inclusión y exclusión planteados. Discusión: la migraña es una cefalea primaria que afecta sobre todo a mujeres jóvenes, las personas que padecen migraña con aura presentan un incremento de riesgo de enfermedad cardiovascular ocasionado por disfunción endotelial. El riesgo global es bajo, sin embargo se hace énfasis en la relación existente entre ambos para mejorar la evaluación del riesgo cardiovascular. Conclusiones: existe una estrecha relación entre la migraña con aura y el riesgo de enfermedad cardiovascular, sobre todo en mujeres que tienen otros factores de riesgo cardiovascular. Una adecuada evaluación de dichos factores disminuiría la morbimortalidad de los individuos que padecen de migraña.

Aura sin migraña o síndrome de Alicia en el País de las Maravillas: Caso clínico pediátrico / Aura without migraine or Alice in Wonderland syndrome: Pediatric clinical case

La migraña con aura en pacientes pediátricos es reportada con frecuencia; el aura típica sin migraña, en raras ocasiones, y el aura persistente asociada al denominado síndrome de Alicia en el País de las Maravillas, excepcionalmente. El objetivo de este reporte es presentar un caso clínico correspondiente a la última variedad mencionada. Se trata de una paciente de 6 años de edad, quien tuvo, al menos, dos episodios con estas características antes de presentar un cuadro clínico completo de aura y, consecutivamente, cefalea con más frecuencia. Los estudios complementarios practicados de manera sistemática a la paciente fueron normales, con mejoría clínica con el tratamiento convencional. Se debe sospechar el síndrome en todo paciente que se presente con las características descritas a fin de aproximarse al diagnóstico de aura sin migraña, descartar patologías orgánicas o de otra naturaleza e instaurar la terapéutica adecuada.

Migraine with aura in children is often reported, typical aura without headache is reported sometimes, but persistent aura and Alice in Wonderland syndrome is exceptionally reported. We present a case corresponding to the last one mentioned in a 6-year-old patient who had at least two episodes with the typical characteristics of aura without migraine before developing more frequently the complete clinical picture of aura and subsequently headache. The complementary studies systematically done to the patient were normal and she improved with conventional therapy. It is important to emphasize that the syndrome should be suspected in any patient who presents the described manifestations in order to approach to the diagnosis of aura without migraine, to discard either organic pathology or another cause and to indicate adequate therapeutic measures.

Differences in Characteristics and Comorbidity of Cluster Headache According to the Presence of Migraine

BACKGROUND AND PURPOSE: Cluster headache (CH) can present with migrainous symptoms such as nausea, photophobia, and phonophobia. In addition, an overlap between CH and migraine has been reported. This study aimed to determine the differences in the characteristics of CH according to the presence of comorbid migraine. METHODS: This study was performed using data from a prospective multicenter registry study of CH involving 16 headache clinics. CH and migraine were diagnosed by headache specialists at each hospital based on third edition of the International Classification of Headache Disorders (ICHD-3). We interviewed patients with comorbid migraine to obtain detailed information about migraine. The characteristics and psychological comorbidities of CH were compared between patients with and without comorbid migraine. RESULTS: Thirty (15.6%) of 192 patients with CH had comorbid migraine, comprising 18 with migraine without aura, 1 with migraine with aura, 3 with chronic migraine, and 8 with probable migraine. Compared to patients with CH without migraine, patients with CH with comorbid migraine had a shorter duration of CH after the first episode [5.4±7.4 vs. 9.0±8.2 years (mean±standard deviation), p=0.008], a lower frequency of episodic CH (50.0% vs. 73.5%, p=0.010), and a higher frequency of chronic CH (13.3% vs. 3.7%, p=0.033). Psychiatric comorbidities did not differ between patients with and without comorbid migraine. The headaches experienced by patients could be distinguished based on their trigeminal autonomic symptoms, pulsating character, severity, and pain location. CONCLUSIONS: Distinct characteristics of CH remained unchanged in patients with comorbid migraine with the exception of an increased frequency of chronic CH. The most appropriate management of CH requires clinicians to check the history of preceding migraine, particularly in cases of chronic CH.

Subcortical Volume Changes in Migraine with Aura

BACKGROUND AND PURPOSE: Various features of the cerebral cortex and white matter have been extensively investigated in migraine with aura (MwA), but the morphological characteristics of subcortical structures have been largely neglected. The aim of this study was to identify possible differences in subcortical structures between MwA patients and healthy subjects (HS), and also to determine the correlations between the characteristics of migraine aura and the volumes of subcortical structures. METHODS: Thirty-two MwA patients and 32 HS matched by sex and age were analyzed in this study. Regional subcortical brain volumes were automatically calculated using the FSL/FMRIB Image Registration and Segmentation Tool software (https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Glossary). A general linear model analysis was used to investigate differences in the volume of subcortical structures between the MwA patients and HS. A partial correlation test was used to assess correlations between the volume of subcortical structures and characteristics of MwA. RESULTS: The volumes of the right globus pallidus, left globus pallidus, and left putamen were significantly smaller in MwA patients than in HS (mean±SD): 1,427±135 mm³ vs. 1,557±136 mm³ (p<0.001), 1,436±126 mm³ vs. 1,550±139 mm³ (p=0.001), and 4,235±437 mm³ vs. 4,522±412 mm³ (p=0.006), respectively. There were no significant relationships between subcortical structures and clinical parameters. CONCLUSIONS: These findings suggest that both the globus pallidi and left putamen play significant roles in the pathophysiology of the MwA. Future studies should determine the cause-and-effect relationships, since these could not be discriminated in this study due to its cross-sectional design.

History of Migraine and Volume of Brain Infarcts: The Italian Project on Stroke at Young Age (IPSYS) / 대한뇌졸중학회지

BACKGROUND AND PURPOSE: Migraine has been shown to increase cerebral excitability, promote rapid infarct expansion into tissue with perfusion deficits, and result in larger infarcts in animal models of focal cerebral ischemia. Whether these effects occur in humans has never been properly investigated. METHODS: In a series of consecutive patients with acute ischemic stroke, enrolled in the setting of the Italian Project on Stroke at Young Age, we assessed acute as well as chronic infarct volumes by volumetric magnetic resonance imaging, and compared these among different subgroups identified by migraine status. RESULTS: A cohort of 591 patients (male, 53.8%; mean age, 37.5±6.4 years) qualified for the analysis. Migraineurs had larger acute infarcts than non-migraineurs (median, 5.9 cm³ [interquartile range (IQR), 1.4 to 15.5] vs. 2.6 cm³ [IQR, 0.8 to 10.1], P<0.001), and the largest volumes were observed in patients with migraine with aura (median, 9.0 cm³ [IQR, 3.4 to 16.6]). In a linear regression model, migraine was an independent predictor of increased log (acute infarct volumes) (median ratio [MR], 1.64; 95% confidence interval [CI], 1.22 to 2.20), an effect that was more prominent for migraine with aura (MR, 2.92; 95% CI, 1.88 to 4.54). CONCLUSIONS: These findings reinforce the experimental observation of larger acute cerebral infarcts in migraineurs, extend animal data to human disease, and support the hypothesis of increased vulnerability to ischemic brain injury in people suffering migraine.

Difference in Mean Platelet Volume between Migraine Patients with and without Aura

BACKGROUND: Mean platelet volume (MPV) increases when platelets are activated, and it is known to increase in migraine patients. The aim of this study is to investigate whether there is a difference in MPV or platelet count between migraine patients with (MA) and without aura (MO).METHODS: Migraine patients were recruited from the out-patient department of a hospital between January 2012 and June 2017. Patients were divided into MA and MO groups. Platelet count and MPV were compared between groups, and the frequency of comorbidities such as ischemic stroke and cardiovascular disease, was investigated in both groups.RESULTS: Of the 123 patients, 46 were classified as MA, and 77 were classified as MO. The MPV of the MA group was significantly higher than that of the MO group (8.92±0.17 fL, 6.32±0.28 fL, respectively) (P=0.034). However, platelet count showed no significant difference between groups. Cardiovascular disease and ischemic stroke incidences were significantly higher in the MA group than in the MO group (ischemic stroke: 15.2%, 7.8%, respectively, P=0.027; cardiovascular disease: 10.9%, 6.5%, respectively, P=0.018).CONCLUSION: Mean platelet volume was significantly greater in the MA group than in the MO group. This may be related to the pathophysiological differences between the two conditions.

Índice predictivo para la discapacidad moderada a grave por migraña / Predictive index for moderate to severe disability due to migraine

Se realizó un estudio de casos y testigos en pacientes con migraña, diagnosticados mediante un estudio transversal efectuado en el municipio Bayamo de la provincia Granma, entre enero de 2007 y diciembre de 2009, con el objetivo de construir y validar un índice predictivo del riesgo de desarrollar la discapacidad moderada a grave por migraña. La construcción del índice incluyó la selección de los factores de riesgo y el cálculo de sus ponderaciones. Se obtuvo un índice cuantitativo que fue subdividido en 4 categorías de riesgo, mientras que la validez fue satisfactoria en todos los aspectos evaluados. Dicho índice demostró tener buena capacidad discriminativa (área bajo la curva ROC 0,937) y permitió diagnosticar correctamente a 89,74 por ciento de los pacientes, con sensibilidad de 86,73 por ciento y especificidad de 91,12 por ciento. El índice de Kappa interobservador fue de 0,950 (p=0,000), el global de 0,965 (p=0,000) y el coeficiente Alfa de Cronbach, de 0,627.

A cases and control study was carried out in patients with migraine, diagnosed by means of a cross-sectional study in Bayamo municipality, Granma province, between January, 2007 to December, 2009, with the objective of creating and validating a predictive index for the risk of developing moderate to severe disability due to migraine. The creation of the index included the selection of risk factors and the calculation of its values. A quantitative index was obtained which was subdivided in 4 categories of risk, while the validity was satisfactory in all the evaluated aspects. This index demonstrated to have good discriminative capacity (area under the curve ROC 0.937) and it allowed to diagnose correctly 89.74 percent of the patients, with sensibility of 86.74 percent and specificity of 91.12 percent. The Kappa index between observers was 0.950 (p=0.000), the global index was 0.965 (p=0.000) and the coefficient Alpha of Cronbach, 0.627.

Actualización en la prevalencia de trastornos del equilibrio en pediatría / Update on the prevalence of balance disorders in pediatrics

Las alteraciones del equilibrio son una causa muy común de consulta en pacientes adultos pero mucho menos habitual en la población pediátrica. Cuando esta sintomatología aparece en los niños genera gran preocupación, tanto en los padres, como en los profesionales consultados. Objetivo: Exponer nuestra casuística en alteraciones del equilibrio en pacientes pediátricos y enunciar las patologías prevalentes dividiendo la muestra en grupos etarios. Materiales y Métodos: Se realizó un estudio retrospectivo, observacional, descriptivo y transversal. Se incluyeron pacientes entre 1 y 17 años que consultaron al servicio de otorrinolaringología de un Hospital Pediátrico de alta complejidad entre junio de 2014 y junio de 2017. Resultados: Se incluyeron en el estudio 247 pacientes entre 1 y 17 años; 123/247 (49%) niñas y 124/247 (51%) varones. La mediana de edad fue de 9 años. Los síntomas más frecuentes en la consulta fueron: vértigo (63/247); cefaleas (44/247) y la asociación de vértigo + cefaleas (43/247). Las patologías prevalentes fueron: cefaleas 55/247; cerebelitis aguda 30/247; vértigo paroxístico benigno de la Infancia 21/247; migraña vestibular 21/247. Conclusiones: Ante la presencia de un niño con alteraciones del equilibrio, es muy importante la historia clínica y un minucioso examen otoneurológico pensando en cada prueba qué área o sistema estamos evaluando y dónde estaría localizada la lesión (vía vestíbulo-ocular; vía vestíbulo-espinal, etc.). Es importante diferenciar, dado que es la causa de consulta más frecuente, que no todo paciente que presenta cefaleas y síntomas vestibulares asociados tiene como diagnóstico una migraña vestibular (AU)

Balance disorders are a common reason for consultation in adult patients but are much less frequent in children. When children present with these symptoms it causes great concern, both in the parents and in the professionals consulted. Objective: To present our series of pediatric patients with balance disturbance and to describe the different underlying disorders dividing the patients according to age. Material and methods: A retrospective, observational, descriptive and cross-sectional study was conducted. Patients between 1 and 17 years of age who consulted at the Department of Otolaryngology at a tertiary care hospital between June 2014 and June 2017 were included. Results: 247 patients between 1 and 17 years of age were included in the study; 123/247 (49%) girls and 124/247 (51%) males. Median age was 9 years. The most frequent symptoms at consultation were: Vertigo (63/247); Headaches (44/247), and an association of vertigo + headaches (43/247). The most common diagnosis were: headaches 55/247; acute cerebellitis 30/247; benign paroxysmal vertigo of childhood 21/247; vestibular migraine 21/247. Conclusions: In a child with a balance disorder, the diagnostic interview and a thorough oto-neurological examination are important considering what area or system is evaluated in each test and where the lesion may be located (vestibulo-ocular tract; vestibulo-spinal tract, etc.). Differentiation is important as, considering is the most frequent reason for consultation, not every patient who presents with headache associated with vestibular symptoms has vestibular migraine (AU)

Hemiplegic Migraine Presenting with Unilateral Facial Palsy: A case report / 대한소아신경학회지

Hemiplegic migraine (HM) is a rare subtype of migraine with aura and is accompanied by a fully reversible motor aura. HM can occur in two forms: familial or sporadic. Currently, three genes are related to familial HM. Typically, HM occurs in the first or second decade of life and involves gradually progressing aura symptoms in succession, accompanied by headaches. The aura includes visual, sensory, motor, aphasic and often basilar-type symptoms. Motor aura (weakness) is related to the regions where the sensory aura is involved, and it usually starts at the hand before spreading to the arm and face. Aphasia is a common form of speech aura, but does not typically present as a difficulty in understanding. In this case report, the sensory-motor aura started at the right face and then gradually progressed to the right leg without any symptoms in the ipsilateral upper extremity. To the best of my knowledge, there has been no previous case report for the presentation of a hemiplegic migraine, as in this case report. As there is a possibility of misdiagnosis of Bell's palsy at the early stage of this case, this case report suggests that a physician should consider the rare possibility of stroke or HM when a patient presents with unilateral facial palsy.

Migraine with Aura: Surface-Based Analysis of the Cerebral Cortex with Magnetic Resonance Imaging

OBJECTIVE: Previous migraine studies have reported gray matter alterations in various cortical regions with conflicting results. This study aimed to explore a cortical morphometric difference in migraineurs with aura (MA) compared to healthy subjects (HS) and to delineate a possible difference between the cortical morphological features and different aura phenotypes. MATERIALS AND METHODS: Forty-eight MA and 30 HS that were balanced by sex, age, and educational level were selected for this study. T2-weighted and three-dimensional T1-weighted magnetic resonance imaging (MRI) of the brain were acquired using a 1.5T MRI scanner. Surface-based morphometry from the MRI data was used to identify differences between the MA and HS group, and then between MA subgroups. The MA group was subdivided into migraineurs who experienced only visual aura (MVA) and migraineurs who had visual, somatosensory and dysphasic symptoms (MVA+). RESULTS: The MVA+ group had significantly reduced cortical surface area of the left rostral middle frontal cortex compared with the MVA group (p < 0.001). Migraine patients had significantly reduced volume of the left fusiform gyrus relative to HS (p < 0.001). Also, the sulcal depth increased at the level of the left temporal pole in the MVA+ group relative to the MVA group (p < 0.001). The vertex-by-vertex analysis did not exhibit any significant difference in cortical thickness between MA and HS, and between MVA+ and MVA, when corrected for multiple comparisons. CONCLUSION: Migraineurs with aura demonstrates different morphometric features from HS in multiple cortical regions. MVA+ have different morphometric features in the left frontal and temporal lobe relative to MVA, which could be a source of distinct symptoms and serve as potential biomarkers of different MA subtypes.

Cefalea en el adulto mayor: experiencia de una serie de 727 pacientes en el Hospital Universitario San José Infantil de Bogotá / Headache in the elderly: experience of a series of 727 patients at Hospital Universitario San José Infantil Bogotá Colombia

RESUMEN INTRODUCCIÓN: Dentro de los estudios poblacionales el grupo de adultos mayores es el de mayor crecimiento y Colombia no está ajena a dicha tendencia, por tanto el estudio de la cefalea en el adulto mayor (>65 años) es un reto diagnóstico y terapéutico en neurología. Aunque las cefaleas primarias son las más prevalentes, es importante resaltar que hay un incremento de las causas secundarias. OBJETIVO: Determinar la etiología de la cefalea primaria y secundaria en mayores de 65 años y sus características en el Hospital Universitario San José Infantil (HUSJI) de Bogotá en el periodo comprendido entre enero de 2010 y diciembre de 2015. MATERIALES Y MÉTODOS: Se realizó un estudio descriptivo retrospectivo mediante revisión de historias clínicas, en el que se determinaron las causas de cefalea primaria y secundaria según la Clasificación Internacional de Cefalea, tercera edición (IHS) y algunas de sus características. La búsqueda de estos pacientes se realizó mediante el servicio de estadística y epidemiología del hospital así como bases propias del servicio de neurología. RESULTADOS: Se incluyeron 727 pacientes que ingresaron al servicio de urgencias y hospitalización y que fueron valorados por el servicio de neurología, la edad promedio fue de 72,4 años, con una mayor prevalencia de cefalea en mujeres (70,4 %) con respecto a hombres (29,6 %). De estos 352 (48,42 %) cumplían criterios para cefalea primaria (CP) y 375 (51,58 %) para cefalea secundaria (CS). Las causas más frecuentes de cefalea secundaria fue la cefalea atribuida a desórdenes vasculares craneales o cervicales (CADV) 30 %, cefalea atribuida a desórdenes de la homeostasis (CADH) 23 %, cefalea atribuida a desórdenes del cuello (CADC) 15, 7 %. Las causas más frecuentes de cefalea primaria fueron la migraña sin aura (MSA) 34 %, migraña con aura (MCA) 26 % y cefalea tipo tensión (CTT) 21 %. CONCLUSIÓN: En el Hospital San José infantil encontramos una alta frecuencia de cefalea secundaria. Las causas secundarias en especial las vasculares y metabólicas siempre deben ser buscadas en este grupo de pacientes.

SUMMARY INTRODUCTION: Within a population studies, the older adults in one with the greatest, and Colombia is not unaware of this trend. Therefore the study of headache in the elderly (>65 years) is a diagnostic and challenge in neurology .Although the primary headaches are the most prevalent, but it should be noted there is an increase in secondary causes. OBJECTIVE: To determine the etiology of primary and secondary headache in patients over 65 years of age. Materials and methods: Descriptive and retrospective study by reviewing medical records in which the causes of primary and secondary headache were determined according to the International Classification of Headache 3rd Edition (IHS) and some of its characteristics. The search for these patients is done through the hospital statistics and epidemiology service as well as the own bases of the neurology service. RESULTS: Were incluyed 727 patients, the average age was 72.4 years, with a predominance of headache in women (70, 4%); 352 (48.42%) met criteria for primary headache (PC) and 375 (51.58%) for secondary headache (CS). The most frequent causes of CS were Headache attributed to disorders of homeostasis (CADH) 23%, headache attributed to disorders of the neck (CADC) 15, 7%, headache attributed to cranial or cervical vascular disorders (CADV). The most frequent causes of primary headache were migraine without aura (MSA) 34%, migraine with aura (MCA) 26% and headache type tension (CTT) 21%. CONCLUSION: In our group of patients, we found a higher frequency of secondary headache in patients over 65 years of age. Secondary headaches of vascular and homeostatic origin should always be sought in people over 65 years in our hospital.

Giant Arachnoid Granulations in Headache Mimicking Migraine with Aura

Giant arachnoid granulations have been reported to be associated with headaches, which can be acute or chronic in presentation. In some cases, idiopathic intracranial hypertension, previously called pseudotumor cerebri, may occur. The pathophysiology of these enlarged structures seen as filling defects on imaging is not clearly defined, although they are presumed to cause symptoms such as headache via pressure resulting from secondary venous sinus obstruction. We present a unique presentation of secondary headache in a 39-year-old man with no prior history of headaches found to have giant arachnoid granulations, presenting as migraine with aura.

Migraine Susceptibility Genes in Han Chinese of Fujian Province

BACKGROUND AND PURPOSE: Five single-nucleotide polymorphisms (SNPs) (rs4379368, rs10504861, rs10915437, rs12134493 and rs13208321) were recently identified in a Western population with migraine. These migraine-associated SNPs have not been evaluated in a Han Chinese population. This study investigated the associations of specific SNPs with migraine in a Han population. METHODS: This was a case-control study of Han Chinese residing in Fujian Province. Polymerase chain reaction—restriction-fragment-length polymorphism analysis and direct sequencing were used to characterize the relationships of SNPs in a control group of 200 subjects and in a migraine group of 201 patients. RESULTS: The frequencies of the five SNPs did not differ between patients with migraine and healthy non migraine controls. However, subgroup analysis indicated certain SNPs were more strongly associated with migraine with aura or migraine without aura than with controls. The CT genotype of rs4379368 was more common in migraine patients with aura (75%) than in migraine patients without aura (47.9%) and controls (48.5%) (p<0.05), and the TT genotype of rs10504861 was more common in migraine patients with aura than in controls (8.3% vs. 0.5%) (p<0.05). Meanwhile, the CC genotype of rs12134493 was less common in migraine patients without aura than in controls (80.6% vs. 88%) (p<0.05). CONCLUSIONS: Our findings suggest that the rs4379368 and rs10504861 SNPs are markers for susceptibility to migraine with aura and that rs12134493 is a marker for the risk of migraine without aura in this Han population. Future studies should further explore if these associations vary by ethnicity.

The effectiveness and tolerability of oral acetaminophen/aspirin/caffeine (AAC) combination regimen as an acute treatment for migraine in adults: A meta-analysis of randomized trials

BACKGROUND: Migraine is a highly common disorder that can cause significant disability on an individual, which collectively may lead to a substantial burden for the society. Various expert societies have recommended Acetaminophen/Aspirin/Caffeine (AAC) combination regimen as the first-line drug treatment for migraine attacks; however, there were no pooled evidences summarizing the effectiveness and tolerability of this regimen.OBJECTIVE: To determine the effectiveness and tolerability assessment of oral AAC combination regimen as an acute treatment for migraine in adults.METHODS: Relevant studies from inception to March 2014 were searched in Cochrane CENTRAL, MEDLINE, LILACS, Scopus and metaRegister of Controlled Trials. The Cochrane Collaboration's tool for the assessment of risk of bias was employed. Trials that were randomized, double-blind, parallel-group, placebo and active-controlled were included and the data were employed for meta-analysis. To evaluate the quality of evidence, the GRADE approach was utilized for outcomes with sufficient studies and data.RESULTS: From 225 records identified, 4 trials were included in this review, with a total of 3,608 participants with recorded baseline characteristics. Patient-reported migraine intensity was moderate-severe and the AAC dose used was at 500/500/130 mg. At 2 hours, AAC regimen was statistically different and found to be superior to placebo in terms of pain-free, headache relief, nausea-free, photophobia-free, phonophobia-free and functional disability reduction rates using intension-to-treat analysis. Missing data did not alter the outcome measures generating robust results. Sumatriptan 100 mg was found to be better than AAC in pain-free rate, and phonophobia-free rates at 2 hours. Statistically more patients in the AAC arm experienced "any adverse event" compared to placebo and complaints were commonly nausea and nervousness.CONCLUSION: For adult individuals with moderate-severe migraine, a fixed oral dose of Acetaminophen/Aspirin/Caffeine (AAC 500/500/130 mg) may be used as first-line therapy for the acute treatment of migraine and is only associated with mild, infrequent adverse events.
