RESUMEN

Cyclic vomiting syndrome (CVS) is a disorder characterized by recurrent and unpredictable episodes of intense vomiting, interspersed with periods of apparent wellbeing. This disorder, which primarily affects children and adolescents but can persist into adulthood, has recently been the subject of extensive study and analysis in the medical literature. The aim of the present review is to examine the most important aspects of the epidemiology, pathophysiology, subtypes, diagnostic criteria, and current management of CVS. Even though the exact etiology remains unknown, genetic factors (polymorphisms), nervous system alterations and autonomic dysregulation, and environmental factors (use and abuse of cannabinoids) are postulated as possible triggers. CVS has significant diagnostic challenges, given that there is no specific test for confirming its presence. Thorough evaluation of symptoms and the ruling out of other possible causes of recurrent vomiting are required. Management of CVS typically involves a multidisciplinary approach. Pharmacologic options are explored, such as antiemetics and preventive medications, as well as behavioral and psychologic support therapies. Treatment personalization is essential, adapting it to the individual needs of each patient. Despite advances in the understanding of CVS, it remains a significant clinical challenge. This disorder impacts the quality of life of those affected and their families, underscoring the ongoing need for research and the development of more effective treatment strategies.

RESUMEN

OBJECTIVE: To analyze the response to retreatment in patients with chronic/episodic migraine who discontinued therapy with erenumab/fremanezumab after one year of treatment. METHODS: Observational, retrospective, single-center, multidisciplinary study in patients with chronic/episodic migraine who received therapy with erenumab/fremanezumab for at least one year and discontinued it after achieving an adequate response (optimization). The evaluation of the response after retreatment included the following variables: migraine days per month, MIDAS and HIT-6 scales at the beginning of retreatment and 3 months later. The response was evaluated in different subgroups (episodic/chronic, erenumab/fremanezumab and time until retreatment). RESULTS: 48 patients were included. 70.8% (n=34) required retreatment with mAb, with a median of 3.9 (2.9-6.4) months until reintroduction. Clinical response after retreatment was achieved in 67.6% (n=23) of patients. No statistically significant differences were found in the analyzed subgroups. CONCLUSION: Interruption of treatment with erenumab/fremanezumab for chronic/episodic migraine produces a clinical worsening of the disease requiring retreatment in most cases, approximately after 4 months. Two out of three patients respond positively after restarting monoclonal therapy. This response does not appear to be related to the type of migraine, the specific monoclonal antibody prescribed, or the time to retreatment.

RESUMEN

Migraine is a disease with a high prevalence and incidence, in addition to being highly disabling, causing a great impact on the patient's quality of life at a personal, family and work level, but also social, given its high expense due to its direct (care) and indirect (presenteeism and work absenteeism) costs. The multiple and recent developments in its pathophysiological knowledge and in its therapy require updating and, therefore, in this article the Spanish scientific societies most involved in its study and treatment (SEN, SEMFYC and SEMERGEN), together with the Association Spanish Association for Patients with Migraine and other Headaches (AEMICE), we have developed these updated care recommendations. We reviewed the treatment of migraine attacks, which consisted mainly of the use of NSAIDs and triptans, to which ditans and gepants have been added. We also discuss preventive treatment consisting of oral preventive drugs, botulinum toxin, and treatments that block the action of calcitonin-related peptide (CGRP). Finally, we emphasize that pharmacological treatments must be complementary to carrying out general measures consisting of identifying and managing/deletion the precipitating factors of the attacks and the chronicizing factors, controlling the comorbidities of migraine and eliminating analgesic overuse.

RESUMEN

Introducción El síndrome de nieve visual (SNV) es un trastorno del sistema nervioso central que implica la visión de forma constante de pequeños puntos blancos y negros en la totalidad del campo visual. Desarrollo El SNV puede presentarse desde la infancia hasta la tercera edad, siendo más frecuente en jóvenes y sin diferencia entre géneros. En sus criterios diagnósticos se incluye la presencia de nieve visual, pero también otros fenómenos visuales como palinopsia, fotofobia, nictalopía y otros fenómenos visuales persistentes. La fisiopatología del SNV es desconocida, pero se postulan como mecanismos la hiperexcitabilidad del córtex visual y una disfunción en el procesamiento visual de orden superior. La prevalencia de migraña en los pacientes con SNV es alta en comparación con la población general y cuando se presentan conjuntamente los síntomas son más severos. No se dispone de un tratamiento eficaz, pero el fármaco con mejores resultados es la lamotrigina, recomendándose únicamente en casos seleccionados con alta limitación funcional. Conclusiones El síndrome de nieve visual es una entidad poco conocida e infradiagnosticada, pero el creciente número de investigaciones durante los últimos años ha permitido definir unos criterios diagnósticos y acercarnos a su fisiopatología. Es una entidad íntimamente relacionada con la migraña, con solapamiento de síntomas y probablemente mecanismos fisiopatológicos comunes. (AU)

Introduction Visual snow syndrome (VSS) is a central nervous system disorder that consists of the constant perception of small black and white dots throughout the entire visual field. Development VSS can present from infancy to old age, with greater prevalence in the young population, and shows no difference between sexes. The diagnostic criteria include the presence of visual snow and such other visual phenomena as palinopsia, photophobia, nyctalopia, and other persistent visual phenomena. The pathophysiology of VSS is unknown, but hyperexcitability of the visual cortex and a dysfunction in higher-order visual processing are postulated as potential mechanisms. The prevalence of migraine among patients with VSS is high, compared to the general population, and symptoms are more severe in patients presenting both conditions. No effective treatment is available, but the drug with the best results is lamotrigine, which is recommended only in selected cases with severe functional limitation. Conclusions VSS is a little-known and underdiagnosed entity, but the increasing number of studies in recent years has made it possible to establish diagnostic criteria and begin studying its pathophysiology. This entity is closely related to migraine, with overlapping symptoms and probably shared pathophysiological mechanisms. (AU)

RESUMEN

Background The gut-brain axis describes a complex bidirectional association between neurological and gastrointestinal (GI) disorders. In patients with migraine, GI comorbidities are common. We aimed to evaluate the presence of migraine among patients with inflammatory bowel disease (IBD) according to Migraine Screen-Questionnaire (MS-Q) and describe the headache characteristics compared to a control group. Additionally, we explored the relationship between migraine and IBD severities. Methods We performed a cross-sectional study through an online survey including patients from the IBD Unit at our tertiary hospital. Clinical and demographic variables were collected. MS-Q was used for migraine evaluation. Headache disability scale HIT-6, anxiety-depression scale HADS, sleep scale ISI, and activity scale Harvey–Bradshaw and Partial Mayo scores were also included. Results We evaluated 66 IBD patients and 47 controls. Among IBD patients, 28/66 (42%) were women, mean age 42 years and 23/66 (34.84%) had ulcerative colitis. MS-Q was positive in 13/49 (26.5%) of IBD patients and 4/31 (12.91%) controls (p=0.172). Among IBD patients, headache was unilateral in 5/13 (38%) and throbbing in 10/13 (77%). Migraine was associated with female sex (p=0.006), lower height (p=0.003) and weight (p=0.002), anti-TNF treatment (p=0.035). We did not find any association between HIT-6 and IBD activity scales scores. Conclusions Migraine presence according to MS-Q could be higher in patients with IBD than controls. We recommend migraine screening in these patients, especially in female patients with lower height and weight and anti-TNF treatment (AU)

Introducción El eje intestino-cerebro describe una asociación bidireccional compleja entre las enfermedades neurológicas y gastrointestinales (GI). Las comorbilidades GI son frecuentes en la migraña. Nuestro objetivo fue evaluar la presencia de migraña en pacientes con enfermedad inflamatoria intestinal (EII) y describir las características de la cefalea. Además, analizamos la relación entre la gravedad de la migraña y la EII. Métodos Estudio transversal a través de encuesta electrónica en pacientes con EII de un hospital terciario. Se recogieron variables clínicas y demográficas. Se usó MS-Q para presencia de migraña. Se incluyeron escala de discapacidad de cefalea HIT-6, ansiedad-depresión HADS, sueño ISI y actividad de EII Harvey-Bradshaw y Partial Mayo. Resultados Se incluyeron 66EII y 47controles. Entre los EII, 28/66 (42%) eran mujeres, con una edad media de 42años, y 23/66 (34,84%) tenían colitis ulcerosa. El MS-Q fue positivo en 13/49 (26,5%) de EII y en 4/31 (12,91%) controles (p=0,172). Entre los pacientes con EII, la cefalea fue unilateral en 5/13 (38%) y pulsátil en 10/13 (77%). El sexo femenino (p=0.006), la altura (p=0,003) y el peso más bajos (p=0,002) y el tratamiento con anti-TNF (p=0,035) se relacionaron con la probabilidad de migraña. No encontramos asociación entre el HIT-6 y las escalas de actividad de EII. Conclusiones La presencia de migraña de acuerdo al MS-Q podría ser más alta en los pacientes con EII que en controles. Recomendamos realizar un cribado de migraña en estos pacientes, especialmente en mujeres de menor peso y altura y tratamiento anti-TNF (AU)

RESUMEN

El tratamiento de los ataques de migraña se aconseja en todos los pacientes, utilizando antiinflamatorios no esteroideos cuando el dolor es leve y triptanes cuando la intensidad del dolor es moderada-grave. Sin embargo, la efectividad de estos fármacos es modesta, un porcentaje elevado de pacientes presenta efectos secundarios y los triptanes están contraindicados en las personas con antecedentes de ictus, cardiopatía isquémica o hipertensión mal controlada. Por tanto, es imprescindible disponer de nuevas alternativas terapéuticas. En los últimos años han ido apareciendo nuevos fármacos para los ataques de migraña, entre los que destacan los ditanes (lasmiditán) y los gepantes (ubrogepant y rimegepant). Por otro lado, el eptinezumab, que ha sido aprobado para el tratamiento preventivo de la migraña en adultos, se ha utilizado también para los ataques de migraña. En este manuscrito se revisan los resultados de eficacia y seguridad de los nuevos fármacos para los ataques de migraña que se comercializarán próximamente. (AU)

Treatment of migraine attacks is advised in all patients, using non-steroidal anti-inflammatory drugs when the pain is mild and triptans when the pain intensity is moderate-severe. However, the effectiveness of these drugs is moderate, a high percentage of patients have side effects, and triptans are contraindicated in people with a history of stroke, ischaemic heart disease or poorly controlled hypertension. Hence, there is an urgent need for new therapeutic alternatives. In recent years, new drugs for migraine attacks have become available, most notably ditans (lasmiditan) and gepants (ubrogepant and rimegepant). Furthermore, eptinezumab, which has been approved for the preventive treatment of migraine in adults, has also been used for migraine attacks. This manuscript reviews the efficacy and safety results of the new drugs for migraines that will soon be on the market. (AU)

RESUMEN

Objetivos: Analizar la efectividad y seguridad en vida real de los nuevos anticuerpos monoclonales subcutáneos para la profilaxis de la migraña. Métodos: Estudio observacional retrospectivo llevado a cabo desde enero de 2020 hasta abril de 2021 con pacientes diagnosticados de migraña crónica o episódica. Las variables de interés se analizaron por el personal facultativo farmacéutico en una base de datos anonimizada. Esta base se completa como práctica clínica habitual durante la entrevista clínica en la consulta de pacientes externos. Resultados: Se analizaron 53 pacientes. Se observó una reducción del número de crisis respecto al valor basal a los 3, a los 6 y a los 12 meses de tratamiento, así como de otros fármacos para el tratamiento de la migraña. La mayoría de reacciones adversas descritas fueron de tipo leve, obligando a la suspensión del tratamiento de solo uno de los pacientes. Se describió un aumento de la tensión arterial en varios pacientes, así como una incidencia de estreñimiento superior a los ensayos pivotales. Conclusiones: Este estudio muestra una disminución del número de crisis de migraña y del uso de otros fármacos antimigrañosos tras el uso de anticuerpos monoclonales. Los tratamientos se pueden considerar seguros, observándose una baja incidencia de reacciones adversas graves. La mayoría de pacientes fueron tratados con erenumab. Se dispone de menos datos a medida que avanza del tiempo de estudio, por lo que resulta necesario recopilar más información para conocer el perfil de efectividad y seguridad de estos fármacos a largo plazo.(AU)

Objectives: To analyse the effectiveness and safety in real life of new subcutaneous monoclonal antibodies for the prophylaxis of migraine. Methods: Retrospective observational study conducted from January 2020 to April 2021 with patients diagnosed with chronic or episodic migraine. The variables of interest were collected by the pharmacist in an anonymised database during the clinical interview in the outpatient clinic. This databased is completed as standard clinical practice during the clinical interview in the outpatient clinic. Results: 53 patients were analysed. A reduction in the number of attacks from baseline was observed at 3, 6 and 12 months of treatment, as well as for other migraine treatment drugs. Most of the adverse reactions described were mild, leading to discontinuation of treatment in only one patient. An increase in blood pressure was reported in several patients, as well as a higher incidence of constipation than in pivotal trials. Conclusions: This study shows a decrease in the number of migraine attacks and in the use of other anti-migraine drugs after the use of monoclonal antibodies. The treatments can be considered safe, with a low incidence of serious adverse reactions. Most patients were treated with erenumab. Less information is available as the study time progresses, so more information needs to be collected to understand the long-term effectiveness and safety profile of these drugs.(AU)

RESUMEN

La migraña es una enfermedad que se ha visto asociada a defectos septales auriculares y a su cierre percutáneo, estipulándose en la literatura que sería una rara complicación, pero la evidencia al respecto es escasa. Se realizó una revisión narrativa sobre definiciones, epidemiología, fisiopatología y tratamiento de la migraña y de la entidad migraña poscierre percutáneo de defectos del septum auricular, incluyendo trabajos observacionales (retrospectivos, prospectivos), estudios randomizados, reportes de casos, artículos de revisión y metaanálisis existentes en PubMed y Cochrane, para aportar al conocimiento de esta entidad.

Migraine is a disease that has been associated with atrial septal defects and its percutaneous closure, stipulating in the literature that it would be a rare complication, but evidence is scarce. A narrative review was conducted on definitions, epidemiology, pathophysiology and treatment of migraine and the migraine entity after percutaneous closure of atrial septum defects, including observational studies (retrospective, prospective), randomized studies, case reports, review articles and meta-analyses existing in PubMed and Cochrane, to contribute to the knowledge of this entity.

A enxaqueca é uma doença que tem sido associada a defeitos do septo atrial e seu fechamento percutâneo, estipulando na literatura que seria uma complicação rara, mas as evidências são escassas. Foi realizada uma revisão narrativa sobre definições, epidemiologia, fisiopatologia e tratamento da enxaqueca e da entidade migranosa após fechamento percutâneo de defeitos do septo atrial, incluindo estudos observacionais (retrospectivos, prospectivos), estudos randomizados, relatos de caso, artigos de revisão e metanálises existentes no PubMed e Cochrane, para contribuir com o conhecimento dessa entidade.

RESUMEN

Objetivo los objetivos son conocer la opinión de neurólogos y farmacéuticos hospitalarios sobre aquellos aspectos aún en el debate respecto al papel de los anticuerpos monoclonales anti-CGRP en el tratamiento preventivo de la migraña. Identificar aquellas controversias aún existentes. Proponer recomendaciones consensuadas de mejora asistencial. Y promover el acceso de los clínicos y los pacientes a estos nuevos tratamientos en la prevención de la migraña con fármacos biológicos, a fin de mejorar la atención y seguimiento del paciente. Métodos se identificaron y valoraron recomendaciones para la utilización de fármacos biológicos en la prevención de la migraña a través de la metodología de consenso Delphi, proponiendo 88 aseveraciones agrupadas en 3 temas: un módulo de clínica que trata sobre el manejo de los tratamientos biológicos en la migraña, un módulo de pacientes que trata sobre las estrategias de educación al paciente y mejora de la adhesión y un módulo de coordinación que incluye las aseveraciones relacionadas con las estrategias para mejorar el trabajo conjunto entre los 2 colectivos. Se empleó la escala ordinal de Likert de 9 puntos para puntuar dichas recomendaciones y, posteriormente, los datos se analizaron estadísticamente a través de diferentes métricas. Resultados tras las 2 rondas de consulta, se alcanzó consenso en el acuerdo en 71 aseveraciones (80,7%) y consenso en el desacuerdo en una de ellas (1,1%), quedando como indeterminadas 16 aseveraciones (18,2%) de las 88 debatidas. Conclusiones el alto grado de consenso indica que la opinión de neurólogos y farmacéuticos hospitalarios sobre el papel de los anticuerpos monoclonales anti-CGRP en el tratamiento de la migraña es muy similar y permite identificar aquellas controversias aún existentes, para mejorar la atención y seguimiento del paciente con migraña. (AU)

Objective The objectives are to know the opinion of neurologists and hospital pharmacists on those aspects still under debate regarding the role of anti-CGRP monoclonal antibodies in the preventive treatment of migraine. To identify those controversies that still exist. To propose agreed recommendations for improvement of care. And to promote access of clinicians and patients to these new treatments in the prevention of migraine with biological drugs, in order to improve patient care and follow-up. Methodology Recommendations for the use of biological drugs in the prevention of migraine were identified and evaluated through the Delphi consensus methodology, proposing 88 statements grouped into three themes: a clinical module that deals with the management of biological treatments in migraine; a patient module that discusses patient education and adherence improvement strategies; and a coordination module that includes statements related to strategies to improve joint work between the two groups. The 9-point Likert ordinal scale was used to score these recommendations and, subsequently, the data was statistically analyzed through different metrics. Results After both rounds of voting, consensus was reached in agreement on 71 of the 88 statements (80.7%), leaving one statement (1.1%) with consensus in disagreement and 16 remaining as indeterminate (18.2%). Conclusions The high degree of consensus indicates that the opinion of neurologists and hospital pharmacists on the role of anti-CGRP monoclonal antibodies in the treatment of migraine is very similar and allows identifying those controversies that still exist, to improve the care and follow-up of patients with migraine.

RESUMEN

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.

RESUMEN

Migraine is a prevalent disorder imposing a great, pervasive burden on the bearer’s life. However, research is lacking on the individual and family impact of migraines. This study aims to adapt and validate a Portuguese version of the Impact of Migraine on Partners and Adolescent Children (IMPAC) scale, analyzing its psychometric properties. Four hundred eighty six individuals with migraines answered an online questionnaire, also containing a health-related quality of life measure – SF-12. The IMPAC-P presented good psychometric properties and fit of the theoretical model with three underlying factors – Activity Limitations, Partner Interaction, and Children Interaction. The impact of migraines was higher in women, single or widowed individuals, and those aged 21 to 40, exhibiting a significant and negative correlation with SF-12. The IMPAC-P is a brief, valid, reliable, and sensitive tool for assessing the impact of migraines on the bearer’s life and family in both clinical and research contexts. (AU)

La migraña es un trastorno prevalente que impone una carga grande y generalizada en la vida del que la sufre. No obstante, falta investigación acerca de la repercusión individual y familiar de la misma. El estudio adapta y valida la versión portuguesa de la escala sobre Repercusión de la Migraña en la Pareja e Hijos Adolescentes (IMPAC según sus siglas en inglés), analizando sus propiedades psicométricas. Una muestra de 456 sujetos que padecían migrañas contestó al cuestionario online, que incluía igualmente una medida de calidad de vida relativa a la salud (la SF-12). La escala presenta buenas propiedades psicométricas y un buen ajuste al modelo teórico, con tres factores subyacentes (limitaciones de la actividad, interacción de pareja e interacción entre los hijos). El impacto de las migrañas era superior en las mujeres y personas solteras o viudas así como en las personas de entre 21 y 40 años de edad, habiendo una correlación negativa significativa con la SF-12. Se trata de una herramienta breve, válida, fiable y sensible para evaluar el efecto de las migrañas en la vida de quien las sufre y de la familia, tanto en contextos clínicos como de investigación.

RESUMEN

Introducción. La falta de habituación es el fenómeno neurofisiológico interictal más reproducible en la migraña episódica. El objetivo de este estudio es evaluar el fenómeno de habituación mediante el estudio del reflejo de parpadeo nociceptivo en pacientes con migraña episódica. Sujetos y métodosEstudio observacional transversal de casos y controles. Los pacientes con migraña episódica fueron seleccionados de manera consecutiva, estudiados durante la fase interictal. Se estudió el reflejo de parpadeo nociceptivo, y se realizó un estudio comparativo de simetría, análisis de distancias euclidianas y valoración de prolongación de latencias entre bloques de estimulación. Resultados Se incluyó a 31 pacientes y 16 controles sanos, con una edad media de 32,25 y 32,35 años, respectivamente. Los controles mostraron simetría izquierda-derecha. Las distancias euclidiana y Manhattan demostraron que las medias de las latencias por bloque de los grupos son diferentes y se incrementan según el número de bloques que se comparen. Las medias de las latencias de los bloques no difieren significativamente en el grupo de pacientes con migraña, a diferencia del grupo de sanos. Conclusión Se observó un déficit de habituación en la fase intercrítica en pacientes con migraña episódica frente a controles, medido por la ausencia de prolongación de latencias en el reflejo de parpadeo nociceptivo. (AU)

Introduction. Lack of habituation is the most reproducible interictal neurophysiological phenomenon in episodic migraine. The aim of this study is to evaluate the habituation phenomenon by examining the nociceptive blink reflex in patients with episodic migraine. Subjects and methods. We conducted a cross-sectional observational case-control study. Patients with episodic migraine were selected consecutively and studied during the interictal phase. The nociceptive blink reflex was examined and a study was conducted comparing symmetry, analysis of the Euclidean distances and assessment of latency prolongation between stimulation blocks. Results. Thirty-one patients and 16 healthy controls were included, their mean ages being 32.25 and 32.35 years, respectively. The controls displayed left-right symmetry. The Euclidean and Manhattan distances showed that the means of the block latencies of the groups are different and increase according to the number of blocks being compared. The means of the block latencies do not differ significantly in the migraine patient group, in contrast to what is seen in the healthy group. Conclusion. Habituation deficit was observed in the interictal phase in patients with episodic migraine compared to controls, as measured by the absence of latency prolongation in the nociceptive blink reflex.

RESUMEN

BACKGROUND: Migraine attacks have a high impact on daily activities. There is limited research on the burden of migraine on sexual functioning. OBJECTIVE: To determine the prevalence of sexual dysfunction in patients with migraine and its relationship with migraine features and comorbidities. METHOD: This is a cross-sectional study. We included migraine patients between 18 and 60 years-old from 8 Headache Clinics in Spain. We recorded demographic data and migraine features. Patients fulfilled a survey including comorbidities, Arizona Sexual Experiences Scale, Hospital Anxiety and Depression Scale and a questionnaire about migraine impact on sexual activity. A K-nearest neighbor supervised learning algorithm was used to identify differences between migraine patients with and without sexual dysfunction. RESULTS: We included 306 patients (85.6% women, mean age 42.3±11.1 years). A 41.8% of participants had sexual dysfunction. Sexual dysfunction was associated with being female (OR [95% CI]: 2.42 [1.17-5.00]; p<0.001), being older than 46.5 years (4.04 [2.48-6.59]; p<0.001), having chronic migraine (2.31 [1.41-3.77]; p=0.001), using preventive medication (2.45 [1.35-4.45]; p=0.004), analgesic overusing (3.51 [2.03-6.07]; p<0.001), menopause (4.18 [2.43-7.17]; p<0.001) and anxiety (2.90 [1.80-4.67]; p<0.001) and depression (6.14 [3.18-11.83]; p<0.001). However, only female gender, age, menopause and depression were the statistically significant variables selected in the model to classify migraine patients with or without sexual dysfunction (Accuracy [95% CI]: 0.75 (0.62-0.85), Kappa: 0.48, p=0.005). CONCLUSIONS: Sexual dysfunction is frequent in migraine patients visited in a headache clinic. However, migraine characteristics or use of preventive medication are not directly associated with sexual dysfunction. Instead, risk factors for sexual dysfunction were female gender, higher age, menopause and depression.

Sexual dysfunction was associated with being female (OR [95% CI]: 2.42 [1.17–5.00]; p < 0.001), being older than 46.5 years (4.04 [2.48–6.59]; p < 0.001), having chronic migraine (2.31 [1.41–3.77]; p = 0.001), using preventive medication (2.45 [1.35–4.45]; p = 0.004), analgesic overusing (3.51 [2.03–6.07]; p < 0.001), menopause (4.18 [2.43–7.17]; p < 0.001) and anxiety (2.90 [1.80–4.67]; p < 0.001) and depression (6.14 [3.18–11.83]; p < 0.001). However, only female gender, age, menopause and depression were the statistically significant variables selected in the model to classify migraine patients with or without sexual dysfunction (Accuracy [95% CI]: 0.75 (0.62–0.85), Kappa: 0.48, p = 0.005). Conclusions: Sexual dysfunction is frequent in migraine patients visited in a headache clinic. However, migraine characteristics or use of preventive medication are not directly associated with sexual dysfunction. Instead, risk factors for sexual dysfunction were female gender, higher age, menopause and depression.(AU)

Antecedentes: La migraña tiene un alto impacto en las actividades diarias, pero los datos sobre el impacto de la migraña en el funcionamiento sexual son limitados. Objetivo: Determinar la prevalencia de disfunción sexual en pacientes con migraña y su relación con las características y comorbilidades de la migraña. Métodos: Este es un estudio transversal. Se incluyeron pacientes con migraña de entre 18 y 60 años de ocho consultas de cefalea en España. Registramos datos demográficos y características de migraña. Los pacientes completaron una encuesta que incluía comorbilidades, la Escala de Experiencias Sexuales de Arizona, la Escala de Ansiedad y Depresión Hospitalaria y un cuestionario sobre el impacto de la migraña en la actividad sexual. Se usó un algoritmo de aprendizaje supervisado (k-nearest neighbors) para identificar diferencias entre pacientes con migraña, con y sin disfunción sexual. Resultados: Se incluyeron 306 pacientes (85,6% mujeres, edad media 42,3 ± 11,1 años). El 41,8% de los participantes tenía disfunción sexual. La disfunción sexual se asoció con ser mujer (OR [95%]: 2,42 [1,17-5,00]; p < 0,001), tener más de 46,5 años (4,04 [2,48-6,59]; p < 0,001), tener migraña crónica (2,31 [1,41-3,77]; p = 0,001), uso de medicación preventiva (2,45 [1,35-4.45]; p = 0,004), uso excesivo de analgésicos (3,51 [2,03-6,07]; p < 0,001), menopausia (4,18 [2,43-7,17]; p < 0,001), ansiedad (2,90 [1,80-4,67]; p < 0,001) y depresión (6,14 [3,18-11,83]; p < 0,001). Sin embargo, solo el sexo femenino, la edad, la menopausia y la depresión fueron las variables estadísticamente significativas seleccionadas en el modelo para clasificar a los pacientes con migraña, con o sin disfunción sexual (precisión [IC 95%]: 0,75 (0,62-0,85), kappa: 0,48, p = 0,005). Conclusiones: La disfunción sexual es frecuente en pacientes con migraña que son visitados en una consulta de cefalea.(AU)

RESUMEN

Resumen Introducción : Las cefaleas son la segunda causa de consultas neurológicas en la sala de emergencia pediá trica. Muchos pacientes realizan varias visitas al año por este mismo problema, debemos conocer el tratamiento basado en evidencia. Métodos : Se realizó una búsqueda de publicaciones realizadas en los últimos 5 años en diferentes bases de datos. Discusión : Se presentan recursos para investigar sistemáticamente signos de alarma, recomendaciones para el uso racional de estudio de imágenes. Las cefaleas primarias son causa frecuente de consulta en la sala de emergencia. Se presenta tratamiento que cumple el res paldo científico para su utilización en pacientes con ce faleas primarias de tipo migraña en sala de emergencia.

Abstract Introduction : Headache is the second most frequent cause of neurological consultations in the pediatric emergency department. Patients become frequent visi tors per year due to headaches, evidence-based treat ment should be used. Methods : A search of publications within the last 5 years was conducted in different databases. Discussion : Strategies for a systematic approach in the evaluation of red flags, and recommendations for a rational use in neuroimaging studies are presented. Primary headaches are frequently seen in the emergency department. Migraine evidence-based treatment in the emergency department is reviewed.

RESUMEN

OBJECTIVE: The objectives are to know the opinion of neurologists and hospital pharmacists on those aspects still under debate regarding the role of anti-Calcitonin Gene-related Peptide monoclonal antibodies in the preventive treatment of migraine. To identify those controversies that still exist. To propose agreed recommendations for improvement of care. And to promote access of clinicians and patients to these new treatments in the prevention of migraine with biological drugs, in order to improve patient care and follow-up. METHODOLOGY: Recommendations for the use of biological drugs in the prevention of migraine were identified and evaluated through the Delphi consensus methodology, proposing 88 statements grouped into 3 themes: a clinical module that deals with the management of biological treatments in migraine; a patient module that discusses patient education and adherence improvement strategies; and a coordination module that includes statements related to strategies to improve joint work between the two groups. The 9-point Likert ordinal scale was used to score these recommendations and, subsequently, the data was statistically analysed through different metrics. RESULTS: After both rounds of voting, consensus was reached in agreement on 71 of the 88 statements (80.7%), leaving 1 statement (1.1%) with consensus in disagreement and 16 remaining as indeterminate (18.2%). CONCLUSIONS: The high degree of consensus indicates that the opinion of neurologists and hospital pharmacists on the role of anti-Calcitonin Gene-related Peptide monoclonal antibodies in the preventive treatment of migraine is very similar and allows identifying those controversies that still exist, to improve the care and follow-up of patients with migraine.

RESUMEN

Introducción Los bloqueos anestésicos de nervios pericraneales han constituido un tratamiento habitual de múltiples cefaleas. El más utilizado en la práctica clínica habitual y que cuenta con mayor evidencia que avale su efectividad es el bloqueo del nervio occipital mayor. Métodos búsqueda en Pubmed de Meta-Analysis/Systematic Review de los últimos 10 años, seleccionando para su revisión aquellos metaanálisis, y en su defecto revisiones sistemáticas, acerca del bloqueo del nervio occipital mayor en el tratamiento de las cefaleas. Resultados Se obtuvieron 95 trabajos, 13 incluyeron los criterios de inclusión. Conclusión El bloqueo del occipital mayor es una técnica eficaz y segura, fácil de realizar, y que ha mostrado su utilidad en migraña, cefalea en racimos, cefalea cervicogénica y pospunción lumbar. No obstante, hacen falta más estudios que aclaren su eficacia a largo plazo, su lugar en el tratamiento habitual, la posible diferencia entre diversos anestésicos, la posología más conveniente y el papel del uso concomitante de corticoides (AU)

Introduction Peripheral nerve blocks have been a common treatment for multiple headaches. By far, the greater occipital nerve block is the most used and with the stronger body of evidence in routine clinical practice. Methods We searched Pubmed Meta-Analysis/Systematic Review, in the last 10 years. Of these results, meta-analyses, and in the absence of these systematic reviews, assessing Greater Occipital Nerve Block in headache has been selected for review. Results We identified 95 studies in Pubmed, 13 that met the inclusion criteria. Conclusion Greater occipital block is an effective and safe technique, easy to perform and which has shown its usefulness in migraine, cluster headache, cervicogenic headache and Post-dural puncture headache. However, more studies are needed to clarify its long-term efficacy, its place in clinical treatment, the possible difference between different anaesthetics, the most convenient dosage and the role of concomitant use of corticosteroids (AU)
