Headache as a reason for consultation: the primary care perspective.

INTRODUCTION: Headache is a frequent reason for consultation with primary care (PC) physicians. However, the condition is underdiagnosed and undertreated. One reason for this may be the lack of specific training on headache in PC. METHODS: We conducted a descriptive cross-sectional study of data gathered with a self-administered survey that was completed by PC physicians from our health district. We collected sociodemographic data and information on previous training in neurology and headache, and training needs. RESULTS: The survey was completed by 104 PC physicians, 53% of whom were women; mean age was 49 years. Most respondents worked in urban settings (42.3%) and had been trained via residency (77.9%). Although 65.4% spent more time with patients with headache than with other patients, only 32.7% used the International Classification of Headache Disorders. In our sample, 68.3% of respondents reported a high or very high interest in headache, and 75.9% wished to receive further training on the condition; theoretical and practical courses and update lectures were regarded as the most useful tools. In clinical practice, 90% used triptans and 78% used preventive treatments. The most frequently used drug was amitriptyline; only 22.1% choose topiramate. CONCLUSIONS: PC physicians are in frequent contact with patients with headache and show interest in receiving training on this condition. This could be helpful in designing training programmes aimed at improving quality of care in this area.

[Emergency department management of epileptic seizures in patients with epilepsy]. / Atención en el servicio de urgencias de las crisis epilépticas en pacientes con epilepsia.

AIM: To analyse the care of patients with epilepsy (PwE) who visit the hospital emergency department (ED) due to an epileptic seizure. MATERIALS AND METHODS: Single-centre retrospective observational study, based on the clinical history of the PwE seen in the ED for epileptic seizures between January 2016 and December 2018. Demographic, clinical and ED management variables were collected. Specifically, the results of a computed tomography (CT) brain scan and electroencephalogram and the presence of precipitating factors for epileptic seizures were analysed. RESULTS: A total of 232 PwE were identified, with a mean age of 49.8 years. The most frequent reason for the visit was focal epileptic seizures (50.4%). In 106 cases (45.6%) possible precipitating factors were found, of which poor therapy adherence was the most frequent. An urgent CT brain scan was performed in 67 cases (28.9%) and acute alterations were found in only one patient. An electroencephalogram was carried out in 16 of them (6.9%). Adjustments were made to the antiepileptic treatment in 135 patients (58.1%). A total of 195 were discharged without being hospitalised (84.1%). CONCLUSIONS: PwE accounted for a considerable proportion of the patients seen for epileptic seizures in the ED. The presence of a potentially controllable precipitating factor was identified in almost half of the cases, the most frequent being poor adherence to therapy. In addition, a high number of urgent complementary tests were performed, which in many cases may be unnecessary and avoidable.

Estudio observacional retrospectivo unicéntrico, basado en la historia clínica de los PcE atendidos en el SUH por crisis epilépticas entre enero de 2016 y diciembre de 2018. Se recogieron variables demográficas, clínicas y de manejo en el SUH. De forma específica, se analizó la realización de una tomografía computarizada cerebral y un electroencefalograma, y la presencia de factores precipitantes de crisis epilépticas. Resultados. Se identificó a 232 PcE, con una edad media de 49,8 años. El motivo de atención más frecuente fueron las crisis epilépticas focales (50,4%). En 106 (45,6%) se encontraron posibles factores precipitantes, de entre los cuales, la mala adhesión terapéutica fue el más frecuente. En 67 casos (28,9%) se realizó una tomografía computarizada cerebral urgente, y se encontraron alteraciones agudas en un solo paciente. En 16 (6,9%) se realizó un electroencefalograma. Se realizó un ajuste del tratamiento antiepiléptico en 135 pacientes (58,1%). Fueron dados de alta sin hospitalización 195 (84,1%). Conclusiones. Los PcE representaron una proporción considerable de pacientes atendidos por crisis epilépticas en el SUH. Casi en la mitad de los casos se identificó la presencia de algún factor precipitante potencialmente controlable, y el más frecuente fue la mala adhesión terapéutica. Además, se observó una realización de pruebas complementarias urgentes elevada, que en muchos casos podrían ser prescindibles.

Abiotrophia defectiva, una causa infrecuente de ictus cardioembólico / Abiotrophia defectiva, an infrequent cause of cardioembolic stroke

Abiotrophia defectiva supone una causa poco frecuente de endocarditis con una elevada tasa de embolización en comparación con otras endocarditis por estreptococo. Las complicaciones neurológicas pueden presentarse en el 20-40% de los casos, destacando aneurismas intracraneales y hemorragias subaracnoideas. Su aislamiento en el sistema nervioso central (SNC) es extremadamente raro y en la mayoría de los casos se asocia a procedimientos neuroquirúrgicos previos. Presentamos el caso de una paciente de 51 años que sufrió un ictus isquémico como complicación de una endocarditis por A. defectiva y se revisan los casos de infecciones del SNC causadas por dicho microorganismo. La relevancia del caso radica en su singularidad, debido a la ausencia de enfermedad valvular previa en la paciente y sin historia reciente de procedimientos invasivos o intervenciones quirúrgicas

Abiotrophia defectiva is a rare cause of endocarditis with a high embolization rate compared to other streptococcal endocarditis. Neurological complications may occur in 20-40% of cases, and include intracranial aneurysms and subarachnoid hemorrhage. Its isolation in the central nervous system (CNS) is extremely rare and is associated with previous neurosurgical procedures. We present the case of a 51-year-old patient who suffered an ischemic stroke as a complication of A. defectiva endocarditis, and the cases of CNS infections caused by this microorganism are reviewed. The relevance of the case lies in its singular character, due to the absence of previous valve disease in the patient without a recent history of invasive procedures or surgical interventions

Utilidad del electroencefalograma en el manejo de la epilepsia en el Servicio de Urgencias / Usefulness of electroencephalography for the management of epilepsy in emergency departments

INTRODUCCIÓN: El electroencefalograma (EEG) es una prueba diagnóstica esencial en epilepsia. Su uso en los Servicios de Urgencias (SU) es limitado, estando habitualmente restringido al diagnóstico y el manejo del estado epiléptico no convulsivo (EENC). Sin embargo, pueden existir otras situaciones en las que, por su perfil temporal, el EEG puede ser una herramienta útil en este entorno. MÉTODOS: Estudio observacional retrospectivo, sobre la base de la historia clínica, de los pacientes atendidos en el SU de nuestro hospital por crisis epilépticas (CE) y sospecha de EENC a los que se realizó un EEG, en el periodo 2015-2016, recogiendo variables demográficas y clínicas. RESULTADOS: Se reclutó a 87 pacientes, con una edad media de 44 años. El motivo de consulta más frecuente fue CE, el 59,8% por primera CE (pCE) y el 27,6% por CE en paciente con epilepsia; en 12,6% la sospecha era EENC. Se observaron descargas epileptiformes interictales (DEI) en el 38,4% de los pacientes atendidos por pCE y en el 33,3% de los epilépticos conocidos; el 36,4% de los posibles EENC se confirmaron mediante EEG. El EEG con DEI supuso un inicio o cambio de tratamiento crónico en el 59,8% de los pacientes. CONCLUSIONES: El EEG es una herramienta útil en el manejo de las CE en los SU, tanto de situaciones agudas graves como el EENC, como en el estudio diagnóstico de la epilepsia de debut o no filiada

INTRODUCTION: Electroencephalography (EEG) is an essential diagnostic tool in epilepsy. Its use in emergency departments (ED) is usually restricted to the diagnosis and management of non-convulsive status epilepticus (NCSE). However, EDs may also benefit from EEG in the context of other situations in epilepsy. METHODS: We conducted a retrospective observational study using the clinical histories of patients treated at our hospital's ED for epileptic seizures and suspicion of NCSE and undergoing EEG studies in 2015 and 2016. We collected a series of demographic and clinical variables. RESULTS: Our sample included 87 patients (mean age of 44 years). Epileptic seizures constituted the most common reason for consultation: 59.8% due to the first episode of epileptic seizures (FES), 27.6% due to recurrence, and 12.6% due to suspected NCSE. Interictal epileptiform discharges (IED) were observed in 38.4% of patients reporting FES and in 33.3% of those with a known diagnosis of epilepsy. NCSE was confirmed by EEG in 36.4% of all cases of suspected NCSE. Presence of IED led to administration of or changes in long-term treatment in 59.8% of the patients. CONCLUSIONS: EEG is a useful tool for seizure management in EDs, not only for severe, sudden-onset clinical situations such as NCSE but also for diagnosis in cases of non-affiliated epilepsy and in patients experiencing the first episode of epilepsy

[Juvenile myoclonic epilepsy: long-term prognosis and antiepileptic drug withdrawal]. / Epilepsia mioclónica juvenil: pronóstico a largo plazo y retirada de tratamiento.

BACKGROUND: Juvenile myoclonic epilepsy (JME) is a classic epileptic syndrome that lacks consensus on the possibility of suspending treatment with antiepileptic drugs (AD). METHOD: Retrospective observational study of a series of patients diagnosed with JME with 20 years or more of evolution, focusing on those with withdrawal from AD. RESULTS: The study involved twenty patients (average age 44.1 years, 55% men) with JME of 30 years average evolution and average age at its outset of 14.2 years. The most frequent type of motor crisis was the combination of myoclonic and tonic-clonic seizures (70%); 60% of the patients have been free of seizures for more than five years. Four patients (20%) were withdrawn from AD, two of them with an average age of 23 years and an average time free of seizures of 7.5 years, who relapsed, and the other two with an average age of 39 years and following 23.5 years free of seizures, who currently have been without seizures for two and nine years. CONCLUSIONS: The possibility of withdrawing AD in patients with JME who have been free of seizures over an extended time seems feasible. We suggest taking into account age at withdrawal and prior existence of a prolonged period of time free of seizures.

Neurocardiovascular pathology in pre-manifest and early-stage Huntington's disease.

BACKGROUND AND PURPOSE: Cardiovascular events are a major cause of early death in the Huntington's disease (HD) population. Dysautonomia as well as deterioration of circadian rhythms can be detected early in the disease progression and can have profound effects on cardiac health. The aim of the present study was to determine if patients with HD and pre-manifest mutation carriers present a higher risk of cardiovascular disease than non-mutation-carrying controls. METHODS: This was a prospective, cross-sectional, multicentre study of 38 HD mutation carriers (23 pre-manifest and 15 early-stage patients) compared with 38 age- and gender-matched healthy controls. Clinical and epidemiological variables, including the main haematological vascular risk factors, were recorded. Ambulatory blood-pressure monitoring and carotid intima-media thickness (CIMT) measurement were performed to assess autonomic function and as target-organ damage markers. RESULTS: Most (63.2%) patients with HD (86.7% and 47.8%, respectively, of the early-stage and pre-manifest patients) were non-dippers compared with 23.7% of controls (P = 0.001). CIMT values were in the 75th percentile in 46.7% and 43.5%, respectively, of the early-stage and pre-manifest patients, whereas none of the controls presented pathological values (P = 0.001 and P = 0.006, respectively). Nocturnal non-dipping was significantly associated with CIMT values in patients (P = 0.002) but not in controls. CONCLUSIONS: These results suggest that higher cardiovascular risks and target-organ damage are present even in pre-manifest patients. Although larger studies are needed to confirm these findings, clinicians should consider these results in the cardiovascular management of patients with HD.

[The hypothalamus in Huntington's disease]. / El hipotalamo en la enfermedad de Huntington.

INTRODUCTION: Disorders affecting sleep and the circadian rhythm, autonomic clinical signs and symptoms, and neuroendocrine alterations are frequent characteristics in Huntington's disease, some of which present in early stages of the disease. It is reasonable to think that some of these features could result from a hypothalamic dysfunction affecting the centre regulating sleep, metabolism and the autonomic nervous system. AIM: The study presents the evidence available to date that suggests the involvement of a hypothalamic disorder in Huntington's disease. DEVELOPMENT: Histopathological, hormonal and neuroimaging research relates this area of the brain to Huntington's disease. The experimental findings and those obtained with animal models or in studies conducted with patients are summarised. Likewise, the clinical repercussions (sleep and circadian rhythm disorders, psychiatric and cognitive pathologies, and the clinical signs and symptoms linked to autonomic dysfunction) secondary to possible involvement of the hypothalamus in this disease are also described. CONCLUSIONS: The hypothalamus acts as a centre that integrates the neuroendocrine and autonomic functions, and plays a significant role in cognitive and behavioural signs and symptoms. Disorders of this type have been highlighted in Huntington's disease. Further studies are needed to elucidate the role and scope of this region of the brain in this disease.

TITLE: El hipotalamo en la enfermedad de Huntington.Introduccion. Los trastornos del sueño y del ritmo circadiano, la sintomatologia autonomica y las alteraciones neuroendocrinas son caracteristicas frecuentes de la enfermedad de Huntington, y algunos de ellos se presentan en estadios tempranos de ella. Es plausible pensar que algunos de estos rasgos podrian ser el resultado de una disfuncion hipotalamica del centro regulador del sueño, el metabolismo y el sistema nervioso autonomo. Objetivo. Se exponen las evidencias disponibles hasta el momento actual que sugieren una afectacion hipotalamica en la enfermedad de Huntington. Desarrollo. Investigaciones histopatologicas, hormonales y de neuroimagen relacionan esta region cerebral con la enfermedad de Huntington. Se resumen los hallazgos, tanto experimentales como en modelos animales, o en estudios realizados con pacientes. Asimismo, se describen las repercusiones clinicas (alteraciones del sueño y del ritmo circadiano, la patologia psiquiatrica y cognitiva, y la clinica vinculada con disfuncion autonomica) secundarias a una posible afectacion hipotalamica en esta enfermedad. Conclusiones. El hipotalamo se comporta como un centro integrador de las funciones neuroendocrinas y autonomicas, y presenta un papel no desdeñable sobre la sintomatologia cognitiva y conductual. Alteraciones al respecto se han destacado en la enfermedad de Huntington. Son necesarios posteriores estudios para aclarar el papel y el alcance de esta region cerebral en esta enfermedad.

Relación entre el trastorno de conducta del sueño REM y el trastorno de control de impulsos en pacientes con enfermedad de Parkinson / Association between REM sleep behaviour disorder and impulse control disorder in patients with Parkinson's disease

Introducción: La relación entre el trastorno del control de impulsos (TCI) y el trastorno de conducta del sueño REM (TCSR) no se ha aclarado todavía y los resultados de la literatura son contradictorios. Nuestro objetivo es valorar la asociación entre estos 2 trastornos y, a su vez, su presencia en dependencia de la terapia dopaminérgica. Métodos: Un total de 73 pacientes diagnosticados de enfermedad de Parkinson, en tratamiento con un único agonista dopaminérgico, fueron incluidos en el estudio, tras valoración clínica y habiendo completado el cuestionario de pregunta única para el TCSR y el cuestionario abreviado para los trastornos impulsivo-compulsivos en la enfermedad de Parkinson. Resultados: La edad media ± desviación estándar de los pacientes fue de 68,88±7,758 años. De ellos, 26 pacientes (35,6%) se clasificaron dentro de un TCSR-probable, presentando mayor prevalencia de síndrome rígido acinético no tremórico, más años de tratamiento con levodopa y con agonistas dopaminérgicos, y una relación significativa con el TCI (p=0,001) en comparación con el grupo sin TCSR-probable. En cuanto al tratamiento con agonistas dopaminérgicos, se demostró la asociación significativa de la administración por vía oral con una mayor prevalencia de TCI, mientras que esta vía también se relacionó con mayor tendencia a desarrollar TCSR, diferencias en este caso no significativas. Conclusiones: Nuestros datos confirman que el TCSR se relaciona con el TCI en la enfermedad de Parkinson (AU)

Introduction: The relationship between impulse control disorder (ICD) and REM sleep behaviour disorder (RBD) has not yet been clarified, and the literature reports contradictory results. Our purpose is to analyse the association between these 2 disorders and their presence in patients under dopaminergic treatment. Methods: A total of 73 patients diagnosed with Parkinson's disease and treated with a single dopamine agonist were included in the study after undergoing clinical assessment and completing the single-question screen for REM sleep behaviour disorder and the short version of the questionnaire for impulsive-compulsive behaviours in Parkinson's disease. Results: Mean age was 68.88 ± 7.758 years. Twenty-six patients (35.6%) were classified as probable-RBD. This group showed a significant association with ICD (P=.001) and had a higher prevalence of non-tremor akinetic rigid syndrome and longer duration of treatment with levodopa and dopamine agonists than the group without probable-RBD. We found a significant correlation between the use of oral dopamine agonists and ICD. Likewise, patients treated with oral dopamine agonists demonstrated a greater tendency toward presenting probable-RBD than patients taking dopamine agonists by other routes; the difference was non-significant. Conclusions: The present study confirms the association between RBD and a higher risk of developing symptoms of ICD in Parkinson's disease (AU)

[A study of sexual function in migraine and cluster headache]. / Estudio de la funcion sexual en la migrana y la cefalea en racimos.

INTRODUCTION: The sexual erectile dysfunction are common symptoms and many chronic diseases whose diagnosis will determine the therapeutic management of patients. AIM: To assess sexual function in men with migraine or cluster headache (CH) compared with a control group. SUBJECTS AND METHODS: Cross-sectional study of 34 patients with migraine, 31 patients with CH and 60 control subjects less than 46 years old. Erectile dysfunction was assessed using the International Index of Erectile Dysfunction (IIEF). Emotional state was evaluated using the Beck Depression Inventory. RESULTS: The average score on the IIEF was 68.41 ± 10.09, 64.26 ± 5.73 and 59.33 ± 15.89 in the control group, migraine and CH respectively (p = 0.041) being the significant difference between controls and CH (p = 0.036). In the group of migraine patients, three patients had mild and one moderate erectile dysfunction. In the group of patients with CH, twelve scored in rank of mild erectile dysfunction, and two met the criteria for severe erectile dysfunction (p < 0.05). By analyzing differences in the different domains of IIEF, they were significant in the domain of overall satisfaction (p = 0.015) between the control group and patients with CH (p = 0.012). CONCLUSIONS: In our study we found a higher frequency of and involvement in sexual function in terms of overall satisfaction in patients with migraine and CH. We believe that the evaluation of sexual function in this type of headache should be integrated into our clinical practice.

TITLE: Estudio de la funcion sexual en la migrana y la cefalea en racimos.Introduccion. La disfuncion erectil y sexual son sintomas comunes a muchas enfermedades cronicas cuyo diagnostico va a condicionar el manejo terapeutico de los pacientes. Objetivo. Valorar la funcion sexual en varones con migrana o cefalea en racimos (CR) comparandola con un grupo control. Sujetos y metodos. Estudio descriptivo transversal de 34 pacientes con migrana, 31 pacientes con CR y 60 sujetos control de edad inferior a 46 anos. La disfuncion erectil se valoro con el indice internacional de disfuncion erectil (IIEF), y el estado emocional, mediante el inventario de depresion de Beck. Resultados. La puntuacion media en el IIEF fue de 68,41 ± 10,09, 64,26 ± 5,73 y 59,33 ± 15,89 en los grupos control, con migrana y con CR, respectivamente (p = 0,041), y la diferencia es significativa entre controles y con CR (p = 0,036). En el grupo de pacientes migranosos, tres pacientes tenian disfuncion erectil leve, y uno, moderada. En el grupo de pacientes con CR, 12 puntuaron en rango de disfuncion erectil leve y dos cumplieron criterios de disfuncion erectil grave (p < 0,05). Al analizar las diferencias en los diferentes dominios del IIEF, estas fueron significativas en el dominio de satisfaccion global (p = 0,015) entre el grupo control y los pacientes con CR (p = 0,012). Conclusiones. Hemos encontrado una mayor frecuencia de disfuncion erectil y afectacion de la funcion sexual en terminos de satisfaccion global en los pacientes con migrana y con CR. Creemos que la valoracion de la funcion sexual en este tipo de cefaleas debe integrarse en nuestra practica clinica habitual.

[Mnemonic complaints and chronic migraine]. / Quejas mnesicas y migraña cronica.

INTRODUCTION. Patients with chronic migraine often report lower cognitive performance, which affects their quality of life. AIMS. To analyse whether the mnemonic capacity of patients with chronic migraine is altered or not. SUBJECTS AND METHODS. A cross-sectional study was conducted in patients with chronic migraine evaluated consecutively in our unit, and paired by age (18-60 years) and gender with a control group consisting of cognitively healthy volunteers. The following cognitive instruments were administered: Folstein Minimental State Examination (MMSE), Memory Alteration Test (M@T), Montreal Cognitive Assessment (MoCA) and working memory. RESULTS. A total of 30 patients with chronic migraine were included (mean age: 49.33 ± 10.05 years) paired with a control group of 30 healthy volunteers (mean age: 44.83 ± 10.91 years). The mean elapsed time since onset of the patients with chronic migraine was 4.47 ± 2.74 years. On performing a comparative analysis between the two groups, significant differences were found with overall lower scores in the group of patients with chronic migraine in the MoCA (24.16 versus 29), M@T (43.76 versus 48.8) and working memory tests (17.5 versus 24.26). Performance in the MMSE was similar in both groups. CONCLUSIONS. Patients with chronic migraine can have lower cognitive performance regardless of distracting elements, such as pharmacological factors or psychiatric comorbidity, since chronic migraine can be understood as yet another element within the spectrum of chronic pain.

Se administraron los siguientes instrumentos cognitivos: test minimental de Folstein (MMSE), test de alteracion de memoria (T@M), evaluacion cognitiva de Montreal (MoCA) y memoria de trabajo. Resultados. Se incluyo un total de 30 pacientes con migraña cronica (edad media: 49,33 ± 10,05 años) pareados con un grupo control de 30 voluntarios sanos (edad media: 44,83 ± 10,91 años). El tiempo medio de evolucion de los pacientes con migraña cronica fue de 4,47 ± 2,74 años. Al realizar el analisis comparativo entre ambos grupos, se encontraron diferencias significativas con puntuaciones mas bajas de forma global en el grupo de pacientes con migraña cronica en el test de MoCA (24,16 frente a 29), T@M (43,76 frente a 48,8) y memoria de trabajo (17,5 frente a 24,26). El rendimiento en el MMSE fue similar en ambos grupos. Conclusiones. Los pacientes con migraña cronica pueden tener un menor rendimiento cognitivo independientemente de elementos distractores, como el farmacologico o la comorbilidad psiquiatrica, dado que la migraña cronica puede entenderse como un elemento mas dentro del espectro del dolor cronico.
