RESUMEN
INTRODUCTION: There is an extending use of percutaneous closure of patent foramen ovale (PFO) as therapy for PFO-associated cryptogenic strokes. The aim of our study was to investigate the clinical practice of percutaneous closure of PFO and to analyse the variables for decision-making on the selection of patients for this procedure. METHOD: A prospective observational multicentric survey was conducted using all the cases of cryptogenic stroke/transient ischaemic attack associated with PFO recorded in the NORDICTUS hospital registry during the period 2018-2021. Clinical data, radiological patterns, echocardiogram data and factors related to PFO-associated stroke (thromboembolic disease and paradoxical embolism criteria) were recorded. The indication for closure was analysed according to age (≤/> 60 years) and the characteristics of the PFO. RESULTS: In the group ≤ 60 years (n = 488), 143 patients (29.3%) underwent PFO closure. The most influential variables for this therapy were detection of a high-risk PFO (OR 4.11; IC 2.6-6.5, P < .001), criteria for paradoxical embolism (OR 2.61; IC 1.28-5.28; P = .008) and previous use of antithrombotics (OR 2.67; IC 1.38-5.18; P = .009). In the > 60 years group (n = 124), 24 patients had PFO closure (19%). The variables related to this option were history of pulmonary thromboembolism, predisposition to thromboembolic disease, paradoxical embolism criteria, and high-risk PFO. CONCLUSIONS: The detection of a high-risk PFO (large shunt, shunt with associated aneurysm) is the main criterion for a percutaneous closure-based therapy. Other conditions to consider in the eligibility of patients are the history of thromboembolic disease, paradoxical embolism criteria or the previous use of antithrombotics.

INTRODUCTION: The relationship between socioeconomic status and incidence or stroke mortality rates is well established. The evidence of an association between this variable and survival is less conclusive. Level of education is a widely-used measure of socioeconomic status in elderly people. AIM: To assess the relationship between one-year survival after stroke and level of education. PATIENTS AND METHODS: We analysed data on 544 consecutively recruited patients admitted for acute ischaemic stroke in one the public hospitals of Bizkaia (Spain). Data were obtained through interviews with patients or accompanying persons and from medical records. We studied variables concerning previous functional status, stroke severity, cardiovascular risk factors and stroke care provided. Patients were followed up for 12 months and the dates of any deaths were recorded. Univariate and multivariate analyses were carried out to assess the relationship between level of education and survival. RESULTS: A total of 203 (86%) women and 273 (88.6%) men were alive at 12 months. In both sexes, individuals with a lower level of education had poorer previous functional status, more severe strokes and higher mortality rates. In the multivariate analysis, the association between level of education and survival remained significant in the adjusted model in men. CONCLUSIONS: In our setting, there are differences in the survival of patients with ischaemic stroke as a function of level of education. The impact of this factor was greater in men than women.
TITLE: Relacion del nivel de estudios con la supervivencia en el primer año tras un ictus isquemico.Introduccion. La relacion del nivel socioeconomico con las tasas de incidencia y de mortalidad por ictus esta bien establecida. La evidencia de la relacion con la supervivencia de los pacientes tras el ictus es menos concluyente. El nivel educativo es una medida de nivel socioeconomico muy utilizada en estudios con personas de edad avanzada. Objetivo. Estudiar la relacion de la supervivencia en el primer año tras el ictus con el nivel de estudios. Pacientes y metodos. Se analizaron los datos de 544 pacientes con ictus isquemico agudo ingresados en los hospitales publicos de Bizkaia (España), seleccionados consecutivamente. Se obtuvieron datos por entrevista a pacientes o acompañantes y de historia clinica. Se estudiaron variables sobre situacion funcional previa, gravedad del ictus, factores de riesgo cardiovascular y de atencion al ictus. Se hizo un seguimiento de 12 meses para registrar, en su caso, la fecha de fallecimiento. Se realizo un analisis univariado y multivariado para identificar la relacion del nivel de estudios con la supervivencia. Resultados. Tras 12 meses, sobrevivian 203 mujeres (86%) y 273 hombres (88,6%). En ambos sexos, las personas con menos estudios tuvieron peor situacion funcional previa, mayor gravedad y fallecieron en mayor proporcion. En el analisis multivariado, el nivel de estudios se mantuvo asociado con la supervivencia en el modelo ajustado para los hombres. Conclusiones. La diversidad de nivel educativo marca diferencias en la supervivencia de los pacientes con ictus isquemico en nuestro entorno. El impacto de este factor fue mayor en los hombres que en las mujeres.

INTRODUCTION: According to numerous studies, using emergency medical services (EMS) to transport stroke patients to hospitals decreases diagnostic and treatment delays. OBJECTIVES: To determine the frequency of use of EMS by stroke patients in Bizkaia (Spain), analyse the factors associated with using EMS, and study the impact of EMS on time to care. METHODS: We gathered data from 545 patients hospitalised for acute ischaemic stroke and recruited consecutively. Data were obtained from the patients' medical histories and interviews with the patients themselves or their companions. We studied the following variables: previous health status, stroke symptoms and severity (NIHSS), type of transport, and time to medical care. Univariate and multivariate analyses were performed to identify factors associated with use of EMS and care delays. RESULTS: Patients transported to hospital by the EMS accounted for 47.2% of the total. Greater stroke severity, arriving at the hospital at night, and poor functional status at baseline were found to be independently associated with use of EMS. Use of EMS was linked to earlier arrival at the hospital. Door-to-imaging times were shorter in the EMS group; however, this association disappeared after adjusting for stroke severity. Revascularisation was more frequent among patients transported by the EMS. CONCLUSIONS: EMS transport was associated with shorter prehospital delays. Effective health education programmes should be developed to promote EMS transport for patients with stroke symptoms. In-hospital stroke management should also be improved to reduce time to medical care.

INTRODUCTION: Treatment with lithium can cause several neurological side effects, even at therapeutic levels. CASE REPORT: We report the case of a 49-year-old woman, with bipolar disorder and depression, undergoing treatment with lithium, antidepressants and antipsychotics, who was admitted to hospital due to a clinical picture of visual hallucinations with an elevated lithaemia of 2.1 mEq/L (therapeutic range: 0.6-1.2 mEq/L). The patient developed a severe encephalopathy that required the use of assisted ventilation in the intensive care unit. Initial magnetic resonance imaging showed a reversible bilateral symmetrical hyperintensity in the dentate nuclei in T2 and T2-FLAIR sequences. Over the following months she gradually developed a pancerebellar syndrome with evidence of a marked loss of bilateral volume in the cerebellum, above all at the expense of the vermis, which was accompanied by a permanent and disabling cerebellar syndrome. CONCLUSIONS: Although treatment with lithium can cause a variety of neurological side effects, they are usually reversible. However, they occasionally give rise to permanent and disabling sequelae, as in the case of the patient reported here, with a marked and progressive cerebellar atrophy, accompanied by permanent sequelae in the form of a disabling cerebellar syndrome. The cerebellar neurotoxicity of lithium must be taken into account in the broad differential diagnosis of cerebellar ataxia in adults.
TITLE: Alteraciones reversibles en los nucleos dentados y atrofia cerebral de rapida instauracion debido a neurotoxicidad por litio.Introduccion. El tratamiento con litio puede ocasionar diversos efectos adversos neurologicos, incluso con niveles terapeuticos. Caso clinico. Mujer de 49 años, con trastorno bipolar y depresion, en tratamiento con litio, antidepresivos y antipsicoticos, que ingreso por un cuadro de alucinaciones visuales con una litemia elevada de 2,1 mEq/L (rango terapeutico: 0,6-1,2 mEq/L). Progreso a una encefalopatia grave que requirio asistencia respiratoria en la unidad de cuidados intensivos. La resonancia magnetica cerebral inicial mostro una hiperintensidad simetrica bilateral reversible en los nucleos dentados en las secuencias T2 y T2-FLAIR. A lo largo de los meses posteriores desarrollo de forma progresiva un sindrome pancerebeloso con evidencia de una marcada perdida de volumen bilateral en el cerebelo, sobre todo a expensas del vermis, que se acompaño clinicamente de un sindrome cerebeloso permanente e invalidante. Conclusiones. Aunque el tratamiento con litio ocasiona efectos adversos neurologicos variados, estos suelen ser reversibles. Puede dar lugar a secuelas permanentes e incapacitantes, como la paciente descrita, con una atrofia cerebelosa marcada y progresiva, acompañada de secuelas permanentes en forma de sindrome cerebeloso invalidante. La neurotoxicidad cerebelosa del litio debe considerarse en el amplio diagnostico diferencial que representa la ataxia cerebelosa del adulto.
