ABSTRACT

Introducción: Alrededor de 15 millones de personas sufren un ictus cada año, de los que un 10-15% ocurre en menores de 50 años (ictus en el adulto joven). La prevalencia de los distintos factores de riesgo vascular y las estrategias sanitarias para el manejo del ictus varían a nivel mundial, siendo interesante conocer la epidemiología y las características específicas de cada región. El objetivo de este estudio fue determinar la prevalencia de los diferentes factores de riesgo vascular, la etiología y las características de los ictus isquémicos en el adulto joven en la comunidad autónoma de Aragón. Métodos: Estudio multicéntrico, de corte transversal, realizado por los Servicios de Neurología de todos los hospitales del Servicio Aragonés de Salud (SALUD). Se identificó a todos los pacientes entre 18 y 50 años que ingresaron en cualquiera de estos hospitales con el diagnóstico de ictus isquémico o AIT entre enero del 2005 y diciembre del 2015. Se recogieron variables demográficas, factores de riesgo vascular y tipo de ictus isquémico entre otras. Resultados: En el periodo de estudio, 786 pacientes entre 18 y 50 años ingresaron con el diagnóstico de ictus isquémico o AIT en algún hospital del SALUD, con una tasa anual promedio de 12,3 por 100.000 habitantes. La mediana de su edad fue de 45 años (RIQ: 40-48 años). El factor de riesgo vascular más prevalente fue el tabaquismo, 404 (51,4%). La mayoría fue de causa indeterminada (36,2%), seguida por «otras causas» (26,5%). La mediana de puntuación en la escala NIHSS fue de 3,5 (RIQ: 2,07,0). En total, 211 (26,8%) de los ingresos fueron por AIT. De los pacientes que ingresaron con el diagnóstico de ictus isquémico, 59 (10,3%) se fibrinolizaron. Conclusiones: El ictus isquémico en el adulto joven no es infrecuente en Aragón y en un importante número de casos es de etiología indeterminada, por lo que es necesario implementar medidas que nos permitan mejorar su estudio, disminuir su incidencia y prevenir su recurrencia.

Introduction: Stroke affects around 15 million people per year, with 10%-15% occurring in individuals under 50 years old (stroke in young adults). The prevalence of different vascular risk factors and healthcare strategies for stroke management vary worldwide, making the epidemiology and specific characteristics of stroke in each region an important area of research. This study aimed to determine the prevalence of different vascular risk factors and the aetiology and characteristics of ischaemic stroke in young adults in the autonomous community of Aragon, Spain. Methods: A cross-sectional, multi-centre study was conducted by the neurology departments of all hospitals in the Aragonese Health Service. We identified all patients aged between 18 and 50 years who were admitted to any of these hospitals with a diagnosis of ischaemic stroke or TIA between January 2005 and December 2015. Data were collected on demographic variables, vascular risk factors, and type of stroke, among other variables. Results: During the study period, 786 patients between 18 and 50 years old were admitted with a diagnosis of ischaemic stroke or TIA to any hospital of Aragon, at a mean annual rate of 12.3 per 100 000 population. The median age was 45 years (IQR: 40-48 years). The most prevalent vascular risk factor was tobacco use, in 404 patients (51.4%). The majority of strokes were of undetermined cause (36.2%), followed by other causes (26.5%). The median NIHSS score was 3.5 (IQR: 2.0-7.0). In total, 211 patients (26.8%) presented TIA. Fifty-nine per cent of the patients admitted with a diagnosis of ischaemic stroke (10.3%) were treated with fibrinolysis. Conclusions: Ischaemic stroke in young adults is not uncommon in Aragon, and is of undetermined aetiology in a considerable number of cases; it is therefore necessary to implement measures to improve study of the condition, to reduce its incidence, and to prevent its recurrence.

ABSTRACT

Introducción: La pandemia por COVID-19 ha tenido un impacto en el manejo del ictus isquémico; se ha descrito una disminución de los ingresos hospitalarios e incluso una interrupción en la cadena de atención y un aumento de la mortalidad intrahospitalaria. Sin embargo, falta evidencia sobre su impacto en el pronóstico funcional. El objetivo de este estudio es analizar el efecto de la pandemia por COVID-19 en el pronóstico funcional a 3 meses de los pacientes con ictus isquémico agudo hospitalizados en Aragón.Material y métodosRevisamos los datos de todos los pacientes ingresados por ictus isquémico en todos los hospitales de nuestro sistema sanitario entre el 30 de diciembre del 2019 y el 3 de mayo del 2020. Comparamos su mRS y la mortalidad a 3 meses de los hospitalizados antes y después de haberse establecido el estado de emergencia secundario a la pandemia por COVID-19.ResultadosEn total, 318 pacientes con ictus isquémico agudo cumplieron nuestros criterios de inclusión. No hubo diferencias en las características globales y específicas de cada periodo, excepto por una mayor proporción de pacientes mayores de 80 años de edad durante el periodo pre-CoV (42,2% vs. 29,0%, p = 0,028). En el análisis comparativo, no encontramos una diferencia significativa en la mortalidad (12,3 vs. 7,9, p = 0,465) o la proporción de pacientes con mRS ≤ 2 (57,7% vs. 57,1%, p = 0,425) a los 3 meses.ConclusiónHasta donde sabemos, este es el primer estudio que analiza el impacto de la pandemia por COVID-19 en el pronóstico funcional a 3 meses de pacientes con ictus isquémico. En nuestra comunidad autónoma, no ha habido un incremento en la mortalidad o discapacidad a 3 meses de pacientes hospitalizados por ictus isquémico durante el periodo de COVID-19. (AU)


Introduction: The COVID-19 pandemic has had an impact on ischaemic stroke management, with a reported decrease in hospital admissions, and even disruptions in healthcare and increased in-hospital mortality. However, there is a lack of evidence on the impact of the pandemic on functional prognosis. The aim of this study is to analyse the effect of the COVID-19 pandemic on the 3-month functional outcomes of patients hospitalised due to acute ischaemic stroke in Aragon (Spain).Materil and methodsWe reviewed the data of all patients admitted due to ischaemic stroke to any hospital in our regional healthcare system between 30 December 2019 and 3 May 2020. We compared modified Rankin Scale scores and mortality at 3 months in patients hospitalised before and after the declaration of a state of emergency due to the COVID-19 pandemic.ResultsIn total, 318 patients with acute ischaemic stroke met our inclusion criteria. No differences were observed between periods in global or specific characteristics, with the exception of a higher proportion of patients older than 80 years during the first period (42.2% vs. 29.0%, P=.028). In the comparative analysis, we found no significant differences in mortality (12.3 vs. 7.9, P=.465) or in the proportion of patients with modified Rankin Scale scores ≤ 2 (57.7% vs. 57.1%, P=.425) at 3 months.ConclusionTo our knowledge, this is the first study to analyse the impact of COVID-19 pandemic on the 3-month functional outcomes of patients with ischaemic stroke.

ABSTRACT

Introducción. La hemorragia intracerebral está asociada a una elevada morbimortalidad y su aumento de volumen en fases iniciales conlleva un peor pronóstico. El signo de la mezcla, la densidad heterogénea, la morfología irregular y un nivel líquido en el hematoma se relacionan con un crecimiento precoz del hematoma. Objetivo. Determinar si esas cuatro características se asocian a una mayor mortalidad a los 7, 30 y 90 días de ocurrida la hemorragia intracerebral. Pacientes y métodos. Estudio de cohortes retrospectivo que incluyó a todos los pacientes atendidos en nuestro hospital, entre 2010 y 2015, por una hemorragia intracerebral espontánea con tomografía computarizada cerebral realizada en las primeras seis horas tras el inicio de los síntomas. Resultados. De los 158 pacientes incluidos, 23 (14,6%) presentaban signo de la mezcla, 39 (24,7%) heterogeneidad, 53 (33,5%) irregularidad y 33 (20,9%) nivel líquido. En el análisis bivariante, sólo la heterogeneidad y la irregularidad se asociaron a mayor mortalidad a los 7, 30 y 90 días. En el análisis por regresión logística multivariante, el tratamiento previo con antiagregante plaquetario, una puntuación en la escala de coma de Glasgow menor de 13 y la irregularidad se asociaron a una mayor mortalidad en los siete primeros días. Conclusión. El estudio muestra asociación entre la irregularidad del hematoma y la mortalidad en los siete primeros días. La irregularidad permitiría identificar a pacientes con peor pronóstico, en los que una vigilancia estricta, especialmente de factores relacionados con el crecimiento del hematoma, podría mejorar su pronóstico


Introduction. Intracerebral haemorrhage is associated with high morbidity and mortality, and an increase in its volume in the early phases entails a poorer prognosis. The blend sign, the heterogeneous density, the irregular morphology and a fluid level in the haematoma are related to an early growth of the haematoma. Aim. To determine whether these four characteristics are associated with greater mortality at 7, 30 and 90 days of the occurrence of the intracerebral haemorrhage. Patients and methods. A retrospective cohort study that included all the patients attended in our hospital between 2010 and 2015 for spontaneous intracerebral haemorrhage with a computed tomography brain scan performed in the first six hours following the onset of symptoms. Results. Of the 158 patients included in the sample, 23 (14.6%) presented blend sign; 39 (24.7%), heterogeneity; 53 (33.5%), irregularity; and 33 (20.9%), fluid level. In the bivariate analysis, only heterogeneity and irregularity were associated with increased mortality at 7, 30 and 90 days. In the multivariate logistic regression analysis, previous treatment with an antiplatelet drug, a score on the Glasgow Coma Scale below 13 and irregularity were associated with higher mortality in the first seven days. Conclusion. The study shows an association between irregularity of the haematoma and mortality in the first seven days. Irregularity would allow identification of patients with a more unfavourable prognosis; in these cases, strict surveillance, especially of factors related to the growth of the haematoma, could improve their prognosis

ABSTRACT

Introducción. Los pacientes con migraña crónica (MC) y abuso de medicación son difíciles de tratar y tienen peor calidad de vida que otros pacientes con migrañas. Objetivo. Valorar si la presencia de abuso de fármacos disminuye la efectividad del topiramato. Pacientes y métodos. Una serie de pacientes con MC fueron agrupados según presentasen criterios de abuso o no abuso de fármacos. Se les aconsejo la supresión del fármaco del cual abusaban. Se ajustó el tratamiento de sus crisis y se inició tratamiento preventivo desde el principio con topiramato. Se valoró el número días con cefalea y migrañas intensas en el mes previo y al cuarto mes de tratamiento. Resultados. Fueron seleccionados 262 pacientes con criterios de MC, y de ellos 167 (63,7%) cumplieron criterios de abuso. En ambos grupos hubo una reducción significativa del número de días con cefalea/mes y numero de crisis de migraña/mes al cuarto mes de tratamiento con topiramato. Porcentaje de reducción de días con cefalea/mes en MC sin abuso, 59,3} 36,1%; y con abuso, 48,7} 41,7% (p = 0,0574). Porcentaje de reducción de migrañas intensas/mes en MC sin abuso, 61,2%; y con abuso, 50% (p = 0,0224). Tasa de respondedores según numero de días con cefalea/mes en MC sin abuso, 69%; y con abuso, 57%. Tasa de respondedores según numero de migrañas intensas/mes en MC sin abuso, 76,8%; y en MC con abuso, 61% (p = 0,0097). Conclusiones. El topiramato fue efectivo en pacientes con MC sin y con abuso de fármacos, aunque con menor efectividad en estos últimos (AU)


Introduction: Patients with chronic migraine (CM) and medication abuse are difficult to treat, and have a greater tendency towards chronification and a poorer quality of life than those with other types of headache. Aim: To evaluate whether the presence of medication abuse lowers the effectiveness of topiramate. Patients and methods: A series of patients with CM were grouped according to whether they met abuse criteria or not. They were advised to stop taking the drug that they were abusing. Treatment was adjusted to match their crises and preventive treatment with topiramate was established from the beginning. The number of days with headache and intense migraine in the previous month and at four months of treatment was evaluated. Results. In all, 262 patients with CM criteria were selected and 167 (63.7%) of them fulfilled abuse criteria. In both groups there was a significant reduction in the number of days with headache/month and number of migraine attacks/month at the fourth month of treatment with topiramate. The percentage of reduction in the number of days with headache/ month in CM without abuse was 59.3} 36.1%, and with abuse, 48.7} 41.7% (p = 0.0574). The percentage of reduction in the number of days with intense migraine/month in CM without abuse was 61.2%, and with abuse, 50% (p = 0.0224). Response rate according to the number of days with headache/month in CM without abuse was 69%, and with abuse, 57%. Response rate according to the number of intense migraines/month in CM without abuse was 76.8%, and in CM with abuse, 61% (p = 0.0097). Conclusions. Topiramate was effective in patients with CM with and without medication abuse, although effectiveness is lower in the latter case (AU)

ABSTRACT

INTRODUCTION: Topiramate and onabotulinumtoxin A have proven to be effective in chronic migraine with or without medication abuse according to recent criteria of the International Headache Society's Headache Classification. AIMS: To show that flunarizine is as effective as topiramate in cases of chronic migraine without medication abuse. PATIENTS AND METHODS: We conducted a prospective, non-randomised, comparative study of two groups of patients paired by age and sex, with chronic migraine without abuse, who had been treated preventively for the first time with topiramate or flunarizine. RESULTS: Forty patients treated with flunarizine were assigned a patient of their same sex and age who was being treated with topiramate. The mean rate of reduction in intense migraines in the topiramate group was 59% and in the flunarizine group, 58.5% (p = 0.9444); the responder rate at four months of treatment did not show any significant differences either, the figures being 75% for topiramate and 70% for flunarizine (p = 0.6236). The mean reduction of other headaches in the topiramate group was 57% and in the flunarizine group, 64% (p = 0.4261); the responder rate at four months of treatment was similar in the two groups: 76%. The percentage of dropouts from treatment was higher with topiramate (19.5%) than with flunarizine (10%) (p = 0.3493). No serious side effects occurred in either of the groups. In all, 78.9% of the patients who took topiramate said they were satisfied with the drug versus 75% of those in the flunarizine group (p = 0.7903). CONCLUSIONS: Flunarizine proved to be as effective as topiramate in the treatment of chronic migraine without medication abuse.

La media de reduccion de las migrañas intensas en el grupo del topiramato fue del 59% y en el grupo de la flunaricina, del 58,5% (p = 0,9444); la tasa de respondedores al cuarto mes de tratamiento tampoco mostro diferencias significativas, ya que fue del 75% para el topiramato y del 70% para la flunaricina (p = 0,6236). La media de reduccion de otras cefaleas en el grupo del topiramato fue del 57%, y en el grupo de la flunaricina, del 64% (p = 0,4261); la tasa de respondedores al cuarto mes de tratamiento fue del 76%, similar en ambos grupos. El porcentaje de abandonos del tratamiento fue mayor con el topiramato (19,5%) que con la flunaricina (10%) (p = 0,3493). En ninguno de los dos grupos hubo efectos adversos graves. Un 78,9% de los pacientes que tomo topiramato presento satisfaccion con el farmaco frente al 75% del grupo de la flunaricina (p = 0,7903). Conclusion. La flunaricina mostro ser tan efectiva como el topiramato en el tratamiento de la migraña cronica sin abuso de farmacos.

ABSTRACT

Sleep disorders affect more than 20 percent of the U.S. population, but less than 7 percent have been medically diagnosed. Dentists are ideally positioned to identify many patients who fall under the grouping of sleep-disordered breathing. This paper presents perspectives on sleep-related issues from various medical specialties with a goal to broaden the dentist's appreciation of this topic and open avenues of communication. Algorithms are proposed to guide dentists following positive screenings for sleep-disordered breathing.

ABSTRACT

Introducción. La flunaricina, con nivel de evidencia A, y el nadolol, con nivel de evidencia C, estarían indicados como tratamiento preventivo de la migraña. No existen estudios previos que comparen la efectividad de ambos fármacos. Objetivo. Comparar parámetros de efectividad en grupos independientes de pacientes tratados preventivamente con uno de los fármacos del estudio a los que se aplicó el mismo protocolo. Pacientes y métodos. Se seleccionó a pacientes con migraña episódica (criterios de la Sociedad Internacional de Cefaleas del 2004) que se habían sometido a tratamiento preventivo por primera vez, con flunaricina (5 mg/día) o nadolol (20-40 mg/día). Se analizaron las variables principales de efectividad (reducción del número de crisis al cuarto mes de tratamiento y tasa de respondedores). Resultados. Se incluyó a 227 pacientes con intención de recibir tratamiento: 155 con flunaricina (80,5% mujeres; edad media: 38,3 ± 12,1 años) y 72 con nadolol (63,8% mujeres; edad media: 37,1 ± 12,0 años). La media de crisis en el mes previo al tratamiento fue de 6,09 ± 2,6 en el grupo de la flunaricina y de 5,1 ± 1,7 en el grupo del nadolol (p = 0,0079); la media de crisis al cuarto mes de tratamiento fue de 2,61 ± 2,4 en el grupo de la flunaricina y de 2,77 ± 2,4 en el grupo del nadolol (p = NS). Porcentaje de reducción de migrañas: 55,2% con flunaricina y 50,4% con nadolol (p = NS). La tasa de respondedores fue del 69% con flunaricina y del 67% con nadolol (p = NS). La tasa de respuesta excelente (reducción mayor o igual al 75% de las crisis) fue del 52,2% con flunaricina y del 36,1% con nadolol (p = 0,0077). Porcentaje de efectos adversos: 48,3% con flunaricina frente a 25% con nadolol (p = 0,0009). La tasa de satisfacción fue del 68%, similar en ambos grupos. Conclusión. Tanto la flunaricina como el nadolol mostraron ser efectivos en el tratamiento preventivo de la migraña episódica. La flunaricina se utilizó con mayor frecuencia en nuestro medio y fue peor tolerada (AU)


Introduction. Flunarizine, with level of evidence A, and nadolol, with evidence level C, would be indicated as preventive treatment of migraine. Yet, no previous studies have been conducted to compare the effectiveness of the two drugs. Aim. To compare the effectiveness parameters in independent groups of patients treated preventively with one of the pharmaceuticals from the study, the same protocol being applied in both cases. Patients and methods. The subjects selected for the study were patients with episodic migraine (according to 2004 International Headache Society criteria) who had undergone preventive treatment for the first time, with flunarizine (5 mg/day) or nadolol (20-40 mg/day). The main effectiveness variables (reduction in the number of seizures at four months of treatment and responder rates) were analysed. Results. The study included 227 patients who intended to receive treatment: 155 with flunarizine (80.5% females; mean age: 38.3 ± 12.1 years) and 72 with nadolol (63.8% females; mean age: 37.1 ± 12.0 years). The mean number of seizures prior to treatment was 6.09 ± 2.6 in the flunarizine group and 5.1 ± 1.7 in the nadolol group (p = 0.0079); at four months of treatment it was 2.61 ± 2.4 in the flunarizine group and 2.77 ± 2.4 in the nadolol group (p = NS). Percentage of reduction of migraines: 55.2% with flunarizine and 50.4% with nadolol (p = NS). The responder rate was 69% with flunarizine and 67% with nadolol (p = NS). The excellent response rate (reduction in the number of seizures by 75% or more) was 52.2% with flunarizine and 36.1% with nadolol (p = 0.0077). Percentage of adverse side effects: 48.3% with flunarizine and 25% with nadolol (p = 0.0009). The satisfaction rate was similar in both groups, 68%. Conclusions. Both flunarizine and nadolol proved to be effective in the preventive treatment of episodic migraine. Flunarizine is used more often in our milieu and was less well tolerated (AU)
