[Clinical profile and non-recreational methamphetamine abuse (shabu) among stroke patients in the Philippine population]. / Perfil clínico y abuso de metanfetamina no recreativa (shabú) entre los pacientes con ictus en la población filipina.

INTRODUCTION: Chronic non-recreational use of methamphetamine (shabu) is increasing among the Filipino population in Barcelona. The Asian population presents a different stroke pattern, with a higher incidence of haemorrhage, and different vascular risk factors and health behaviours. The objective of this study is to describe the stroke profile and incidence of methamphetamine use in patients of Filipino origin admitted to our centre. PATIENTS AND METHODS: Demographic data, vascular risk factors, clinical data and prognosis were recorded. Methamphetamine exposure was analysed in plasma samples collected on admission, which were then analysed by liquid chromatography-mass spectrometry. RESULTS: Of a total of 6,418 stroke patients, 73 (1.1%) were identified as being of Filipino origin. The mean age was 54.4 ± 12.1 years, 54% were male and the stroke was ischaemic in 64.4% of cases. Arterial hypertension was the main risk factor. Ten (13.7%) patients tested positive for methamphetamine and amphetamine. These results confirm recent substance use prior to the stroke, mostly in men (80%). In patients who were consumers, 60% had a haemorrhagic stroke, with a poor functional prognosis at three months in 55.6% of patients. CONCLUSIONS: In our setting, patients of Filipino ethnicity admitted for stroke related to the consumption of shabu belonged a younger age bracket, with a lower prevalence of vascular risk factors and a predominance of the haemorrhagic subtype. Methamphetamine testing in Filipino stroke patients is recommended due to the high prevalence of methamphetamine use in our country.

TITLE: Perfil clínico y abuso de metanfetamina no recreativa (shabú) entre los pacientes con ictus en la población filipina.Introducción. En la población filipina de Barcelona está aumentando el consumo crónico no recreativo de metanfetaminas (shabú). La población asiática presenta un patrón de ictus diferente, con mayor incidencia de hemorragias, y diferentes factores de riesgo vascular y conductas de salud. El objetivo es describir el perfil de ictus e incidencia de consumo de metanfetaminas en pacientes de origen filipino ingresados en nuestro centro. Pacientes y métodos. Se registraron datos demográficos, factores de riesgo vascular, datos clínicos y pronóstico. Se analizó la exposición a metanfetamina en muestras de plasma recogidas en el ingreso, que se analizaron por cromatografía líquida-espectrometría de masas. Resultados. Del total de 6.418 pacientes con ictus, se identificó a 73 pacientes filipinos (1,1%). La edad media era de 54,4 ± 12,1 años, el 54% eran hombres y el ictus era isquémico en el 64,4%. La hipertensión arterial fue el principal factor de riesgo. Diez (13,7%) pacientes dieron positivo a metanfetamina y anfetamina. Estos resultados confirman un consumo reciente de sustancias previo al ictus, principalmente en hombres (80%). En pacientes consumidores, un 60% presentaba un ictus hemorrágico, con mal pronóstico funcional a tres meses en el 55,6% de los pacientes. Conclusiones. En nuestro medio, los pacientes de etnia filipina ingresados por ictus en relación con consumo de shabú presentaron un perfil de edad más joven, con menor prevalencia de factores de riesgo vascular y predominio del subtipo hemorrágico. Se recomienda la determinación de metanfetamina en los pacientes filipinos con ictus debido a la alta prevalencia del consumo de metanfetamina en nuestro país.

Description of stroke mimics after complete neurovascular assessment. / Estudio descriptivo de los stroke mimics después de un estudio neurovascular completo.

INTRODUCTION: A considerable percentage of events initially diagnosed as ischaemic stroke have non-cerebrovascular causes; these are called stroke mimics (SM). Currently available evidence about these events is heterogeneous and comes from studies with small samples. OBJECTIVE: The purpose of our study is to identify conditions that may present as SM, define their epidemiological and clinical characteristics, and determine the percentage of cases of SM treated with intravenous fibrinolysis. METHODS: Prospective study including all patients admitted to a tertiary university hospital between June 2005 and April 2015 with a diagnosis of acute stroke. We analysed demographic data, cardiovascular risk factors, time from code stroke activation to admission, stroke severity (NIHSS), final destination after discharge, degree of disability (mRS), and treatment. We compared SM and ischaemic strokes. We ruled out patients with intracranial haemorrhage, subarachnoid haemorrhage, or other causes of SM that may be detected on the baseline CT scan. RESULTS: Four hundred four of the 4,570 included patients (8.8%) were found to have SM. Patients with SM were younger (70.3 vs. 74, P<.0001), less likely to exhibit cardiovascular risk factors and atrial fibrillation (13 vs. 34%, P<.0001), scored lower on the NIHSS at baseline (2 vs. 4, P<.0001), and included fewer cases of aphasia (9.4 vs. 19.6%, P<.02) and dysphagia (1.2 vs. 17%, P<.0001) than patients with stroke. SM caused fewer code stroke activations (28 vs. 40%, P<.0001). Patients with SM required shorter hospital stays (4.9 vs. 7.8 days, P<.0001), were less frequently admitted to the stroke unit (47 vs. 60%, P<.0001) and more frequently discharged home (95 vs. 62%, P<.0001), and had better outcomes (mRS scores 0-2; 76 vs. 54%, P<.0001). Intravenous fibrinolysis was administered to 4.7% of these patients. Epileptic seizures were the most frequent cause of SM (26%). CONCLUSIONS: In our sample, 8.8% of all diagnoses of ischaemic stroke were SM. These events have different demographic, clinical, and prognostic characteristics; epilepsy is the most common aetiology. Despite receiving specialised emergency care, 19 patients with SM (4.7%) were treated with intravenous fibrinolysis.

[Cerebral haemorrhage in patients treated with oral anticoagulation]. / Hemorragia cerebral en pacientes en tratamiento con anticoagulantes orales.

INTRODUCTION: Intracranial haemorrhage (ICH) during dicumarinic treatment is a complication related to anticoagulation intensity with a high level of mortality. The aim of our study is to analize etiology, location and outcome of intracerebral haemorrhages related with anticoagulant therapy. PATIENTS AND METHODS: Over 401 spontaneous intracranial haemorrhages consecutively admitted in the neurological ward, we analyzed the acenocumarol ICH by location, anticoagulation range and factors that conditioned the outcome. RESULTS: We identified 26 patients, 6.5% of total ICH. Mean age was 75.2 +/- 7.9 years-old, over the rest of ICH. International Normalized Ratio (INR) was less than 2 in 10 patients, between 2 and 3 in six and greater than 3 in ten patients. 8 patients (31%) died, three of them had multiple ICH, but none of them had a INR greater than 2. Dicumarinic haemorrhages were of lobar location in 14 cases (three of them multiples) and deep in 12 cases. CONCLUSIONS: In our study, dicumarinic ICH are responsible of 6.5% total intracranial haemorrhages and they are not in clear relation with excessive anticoagulation. Mortality is slightly greater than the other ICH. Relatively benignity of these patients, the age and lobar location suggest that the etiology of these haemorrhages can be related to a subjacent amyloid angiopathy.
