RESUMO
Resumen El nuevo síndrome respiratorio agudo severo por coronavirus tipo 2 (SARS-CoV-2) que causa la enfermedad por COVID-19, se detectó por primera vez en diciembre de 2019. En donde se ha visto que existe un estado protrombótico con afección al sistema nervioso central, con afectación a vasos de gran calibre como la arteria cerebral media, se debe a mecanismos inducidos por la propia infección, estado de hipercoagulabilidad y daño endotelial. Las manifestaciones neurológicas en el COVID-19 se encuentran en el 36% de los pacientes. Descripción del caso: Se trata de un paciente del sexo masculino, de 36 años de edad, con fiebre, tos y malestar general, a quien se le realizó una prueba COVID que resultó positiva, con empeoramiento del cuadro al que se agregó fotofobia, hemiparesia derecha y desviación de la comisura labial hacia la izquierda, por lo que fue llevado a un facultativo 8 horas después del inicio del cuadro clínico. Ahí se realizó una tomografía de cráneo simple que evidenció infarto extenso de la arteria cerebral media izquierda, con edema cerebral maligno, el cual se derivó a manejo quirúrgico de urgencia donde se le realizó una craniectomía descompresiva izquierda extensa. Después de esto, se mantuvo con asistencia respiratoria por intubación mecánica y medidas antiedema cerebral, y se logró que hubiera progresión ventilatoria; sin embargo, se le realizó traqueostomía y gastrostomía por presentar malos predictores de extubación. Se mantuvo en observación posquirúrgica y quedó con hemiparesia 3/5 derecha, sin algún otro déficit, por lo que se dio egreso a domicilio. Discusión: El caso presentado fue manejado con craniectomía descompresiva extensa, y se obtuvo mejoría en la supervivencia y pronóstico funcional, al igual que lo reportado en la literatura médica, en donde se recomienda que dicho manejo se realice de forma temprana. Conclusiones: El presente informe nos revela que aquellos pacientes hombres jóvenes en la cuarta y quinta década de la vida, con COVID-19 e infarto de arteria cerebral media, se presentan sin comorbilidades al darse tratamiento temprano con hemicraniectomía descompresiva, el cual mejora su pronóstico de vida, concordando con los casos presentados en la literatura médica.
Abstract The new severe acute respiratory syndrome due to coronavirus type 2 (SARS-CoV-2), which causes COVID-19 disease, was detected for the first time in December 2019. Where it has been seen that there is a prothrombotic state with involvement of the Central Nervous, with involvement of large vessels such as the middle cerebral artery, is due to mechanisms induced by the infection itself, hypercoagulable state and endothelial damage. Neurological manifestations in COVID-19 are found in 36% of patients. Case description: This is a 36-year-old male patient with fever, cough and general malaise. A COVID test was performed, which came out positive. His condition was getting worse adding photophobia, right hemiparesis and deviation of the corner of the mouth to the left, which is why he went to the doctor, arriving 8 hours after the onset of the clinical picture, where a simple skull tomography was performed, showing extensive infarction of the left middle cerebral artery with malignant cerebral edema. He was transferred to emergency surgical management where a left decompressive craniectomy was performed. After this, mechanical respiratory assistance with intubation and anti-cerebral edema measures were maintained, achieving ventilatory progression; however, a tracheostomy and gastrostomy were performed due to poor predictors of extubation. He was kept under post-surgical observation, leaving him with 3/5 right hemiparesis, without any other deficit, therefore, he was discharged home. Discussion: The case presented was managed with decompressive craniectomy, resulting in an improvement in survival, as reported in the literature where it is recommended that such management should be performed early. Conclusions: This report reveals that patients with COVID-19 present in young men in the fourth and fifth decade of life, without comorbidities, that recieved early treatment with decompressive hemicraniectomy, improved their life prognosis, consistent with the cases presented in the literature.

Introduction: Ischemic stroke in young adults has emerged as a relevant health problem today due to its increased incidence, high mortality, the duration of the disability and social consequences. Objective: To describe an approach in diagnosis of ischemic stroke in young adults based on etiopathogenic classification, history and complementary investigations. Method: A wide-ranging bibliographic review was carried out using Google Scholar, searching in bibliographic databases like PubMed, SciELO and Medline, and searching different keywords; 32 articles were chosen in the process with title and abstract were linked with the subject of this review. Development: The etiopathogenic subtypes of ischemic stroke in young adults differ with regard to older adults, and its etiologic causes are more diverse and heterogeneous. Risk factors, personal and family pathological history, non-neurological and neurological clinical manifestations, allow an approach to diagnosis, while complementary investigations facilitate the confirmation of diagnosis, the location and size of the ischemic infarction, definition of the etiological cause and the support of therapeutic decisions. Final considerations: The history and clinical manifestations obtained through interrogation and physical examination, in association with complementary investigations, made it possible an approach to diagnosis of etiopathogenic subtype and the cause of ischemic brain infarction in young adults improving treatment possibilities.(AU)

Introducción. El signo de la arteria cerebral media (ACM) hiperdensa evaluada por tomografía simple permite predecir la enfermedad vascular cerebral isquémica (EVCi) con oclusión de un gran vaso, sin embargo, es frecuente identificar este signo en pobladores con niveles altos de hemoglobina sin clínica de EVCi. Objetivos. Evaluar la correlación entre la radiodensidad de la ACM y el nivel de hemoglobina en pacientes con y sin EVCi, residentes en una ciudad a gran altitud. Métodos. Estudio observacional analítico, se incluyeron personas residentes de Cusco (ubicada a 3300 msnm) que acudían al servicio de emergencia y se les realizó una tomografía cerebral, presentando o no clínica de EVCi. Se realizó la medición de la radiodensidad de la ACM y se correlacionó con el nivel de hemoglobina. Resultados. Se incluyeron 279 pacientes, el promedio de hemoglobina fue de 15,1 mg/dL y desviación estándar (DE) de 2,5 mg/dL, en los controles se identificó una correlación significativa (r = 0,425, p<0,01) entre la radiodensidad de la ACM con el nivel de hemoglobina. En los casos con EVCi derechos, la radiodensidad de la ACM derecha fue de 46,9 (DE = 7,7 UH) y de la izquierda fue de 46,1 (DE = 6,6 UH), sin que existan diferencias estadísticas (p = 0,24). Tampoco se encontró diferencias en los casos con EVCi izquierdos. Conclusión. Sí existe una correlación entre la radiodensidad de la ACM con el nivel de hemoglobina en los pobladores que viven a gran altitud, sin embargo, no se logró demostrar diferencias significativas entre la radiodensidad entre las ACM afectada y la contralateral en los casos de un EVCi.
Introduction. The sign of the hyperdense middle cerebral artery (MCA) evaluated by simple tomography allows predicting ischemic cerebrovascular disease (ICD) with occlusion of a large vessel, however, it is common to identify this sign in residents with high hemoglobin levels without symptoms of ICD. Objectives. To evaluate the correlation between the radiodensity of the MCA and the hemoglobin level in patients with and without ICD, residing in a high-altitude city. Methods. Analytical observational study, including people residing in Cusco (located at 3300 masl) who attended the emergency service and underwent a brain tomography, presenting or not ICD symptoms. ACM radiodensity was measured and correlated with the hemoglobin level. Results. 279 patients were included, the average hemoglobin was 15.1 and standard deviation (DE) of 2.5 mg/dL, in the controls a significant correlation was identified (r = 0.425, p<0.01) between the radiodensity of the MCA with the hemoglobin level. In the cases with right ICD, the radiodensity of the right MCA was 46.9 (DE = 7.7 HU) and of the left it was 46.1 (DE = 6.6 HU), with no statistical differences (p=0 ,24). No differences were found in the cases with left ICD either. Conclusion. There is a correlation between the radiodensity of the MCA with the hemoglobin level in the inhabitants who live at high altitudes, however, it is not possible to demonstrate significant differences between the radiodensity between the affected MCA and the contralateral one in the cases of an ICD.
RESUMO
INTRODUCTION: Glycaemic variability (GV) refers to variations in blood glucose levels, and may affect stroke outcomes. This study aims to assess the effect of GV on acute ischaemic stroke progression. METHODS: We performed an exploratory analysis of the multicentre, prospective, observational GLIAS-II study. Capillary glucose levels were measured every 4 hours during the first 48 hours after stroke, and GV was defined as the standard deviation of the mean glucose values. The primary outcomes were mortality and death or dependency at 3 months. Secondary outcomes were in-hospital complications, stroke recurrence, and the impact of the route of insulin administration on GV. RESULTS: A total of 213 patients were included. Higher GV values were observed in patients who died (n = 16; 7.8%; 30.9 mg/dL vs 23.3 mg/dL; p = 0.05). In a logistic regression analysis adjusted for age and comorbidity, both GV (OR = 1.03; 95% CI, 1.003-1.06; p = 0.03) and stroke severity (OR = 1.12; 95% CI, 1.04-1.2; p = 0.004) were independently associated with mortality at 3 months. No association was found between GV and the other outcomes. Patients receiving subcutaneous insulin showed higher GV than those treated with intravenous insulin (38.95 mg/dL vs 21.34 mg/dL; p < 0.001). CONCLUSIONS: High GV values during the first 48 hours after ischaemic stroke were independently associated with mortality. Subcutaneous insulin may be associated with higher VG levels than intravenous administration.

Abstract Background It is estimated that headache attributed to ischemic stroke occurs in 7.4% to 34% of the cases. Despite its frequency, this headache has been little studied in terms of its risk factors and characteristics. Objective To assess the frequency and clinical characteristics of headache attributed to ischemic stroke and the factors associated with its occurrence. Methods The present was a cross-sectional study which included patients consecutively admitted within 72 hours of the onset of ischemic stroke. A semi-structured questionnaire was used. The patients underwent magnetic resonance imaging. Results A total of 221 patients were included, 68.2% of whom were male, and the mean age was of 68.2 ± 13.8 years. The frequency of headache attributed to ischemic stroke was of 24.9% (95% confidence interval [95%CI]: 19.6-31.1%). The headache had a median duration of 21 hours and most frequently began at the same time as the focal deficit (45.3%), with a gradual onset (83%). It was of moderate intensity, pulsatile (45.3%), bilateral (54.6%), and presented a similar pattern to that of tension-type headache (53.6%). Headache attributed to stroke was significantly associated with previous tension-type headache, and previous migraine with and without aura (logistic regression). Conclusion Headache attributed to stroke is common, with a pattern similar to that of tension-type headache, and it is associated with a history of tension-type and migraine headaches.
Resumo Antecedentes A cefaleia atribuída ao acidente vascular cerebral isquêmico (AVCi) tem uma frequência de 7,4% a 34% dos casos. Apesar de ser considerada frequente, esta cefaleia ainda é pouco estudada em termos de seus fatores de risco e características. Objetivo Avaliar a frequência e as características clínicas da cefaleia atribuída ao AVCi e os fatores associados com a sua ocorrência. Métodos Este foi um estudo transversal que incluiu pacientes admitidos consecutivamente com até 72 horas do início do AVCi. Foi utilizado um questionário semiestruturado. Os pacientes realizaram ressonância magnética. Resultados Foram incluídos 221 pacientes, 68,2% dos quais eram do sexo masculino, e com idade média de 68,2 ± 13,8 anos. A frequência da cefaleia atribuída ao AVCi foi de 24,9% (intervalo de confiança de 95% [IC95%]: 19,6-31,1%). A duração mediana da cefaleia foi de 21 horas, e ela se iniciou com mais frequência ao mesmo tempo em que o déficit focal (45,3%), teve instalação gradual (83%), foi de moderada intensidade, pulsátil (45,3%), bilateral (54,6%) e teve um padrão semelhante ao da cefaleia de tipo tensional (53,6%). A cefaleia atribuída ao AVCi esteve significativamente associada à cefaleia de tipo tensional prévia, e à migrânea com e sem aura prévias (regressão logística). Conclusão A cefaleia atribuída ao AVCi é frequente, tem padrão mais habitual semelhante ao da cefaleia de tipo tensional, e está associada aos antecedentes de cefaleia de tipo tensional e migrânea.

RESUMO
Introducción: El síndrome de Anton-Babinsky es un trastorno neuropsiquiátrico poco frecuente, que se manifiesta por anosognosia y ceguera cortical, debido a lesiones en las áreas visuales asociativas de la corteza occipital sin presentar afectación en la vía visual. En adultos mayores sus manifestaciones clínicas suelen ser atípicas y la valoración geriátrica integral permite orientar el diagnóstico, que se puede asociar con síndromes geriátricos. Objetivo: Describir las manifestaciones clínicas, síndromes geriátricos, paraclínicos y tratamiento de un paciente con Síndrome de Anton-Babinsky. Caso clínico: Paciente de 85 años, quien durante un postoperatorio inmediato de cirugía ocular (pterigión) presentó alteración fluctuante del estado de conciencia, alucinaciones visuales, disminución de la agudeza visual bilateral y anosognosia. La analítica sanguínea no reportó alteraciones y la tomografía computarizada de cráneo documentó isquemia occipital bilateral, se le diagnosticó síndrome de Anton-Babinsky. Conclusiones: El síndrome de Anton-Babinsky puede tener presentación atípica a través de síndromes geriátricos. La valoración geriátrica integral permite realizar un diagnóstico y manejo multicomponente oportuno con el objetivo de influir en el pronóstico tanto a corto como a largo plazo(AU)
Introduction: Anton-Babinski syndrome is a rare neuropsychiatric disorder, with a manifestation of anosognosia and cortical blindness, due to lesions in the associative visual areas of the occipital cortex without presenting visual pathway impairment. In elderly adults, its clinical manifestations are usually atypical and a comprehensive geriatric assessment allows to guide the diagnosis, which can be associated with geriatric syndromes. Objective: To describe the clinical manifestations, geriatric syndromes, paraclinical findings and treatment of a patient with Anton-Babinski syndrome. Clinical case: This is the case of an 85-year-old patient who, during the immediate postoperative period after ocular surgery (pterygium), presented a fluctuating alteration of consciousness, visual hallucinations, decreased bilateral visual acuity and anosognosia. Blood analysis reported no alterations and cranial computed tomography documented bilateral occipital ischemia; the patient was diagnosed with Anton-Babinski syndrome. Conclusions: Anton-Babinski syndrome may have an atypical presentation through geriatric syndromes. Comprehensive geriatric assessment allows for timely multicomponent diagnosis and management with the aim of influencing both short- and long-term prognosis(AU)

Introducción . El LES pediátrico (LESp) representa el 15% de todos los pacientes con LES. La afectación renal y neuropsiquiátrica es más agresivo en el LESp, siendo la afectación de un solo órgano la forma clínica de aparición más común. Formas de presentación como infarto cerebral y serositis son manifestaciones poco frecuentes en el LESp. El tratamiento de un LESp no difiere al de las formas adultas y el arsenal terapéutico es el mismo. El rituximab (RTX) es un agente biológico utilizado a nivel mundial en LES con excelentes resultados, sin embargo, aún no existe consenso sobre su eficacia real en LESp. Objetivos . Presentación de 2 casos de LESp con infarto cerebral y serositis como forma de presentación, que no respondieron a la terapia convencional pero sí a RTX. Métodos . Reporte de caso, con descripción del cuadro clínico, método diagnóstico y forma de tratamiento. Resultados. Primer caso: mujer de 16 años que consulta por cefalea progresiva con crisis tónico-clónica. La tomografía cerebral mostró un infarto cerebral frontoparietal izquierdo. En el examen físico se encontró livedo reticularis en miembros inferiores, dolor articular, caída del cabello y úlceras orales. Las pruebas revelaron anemia normocítica, trombocitopenia, disminución del complemento, 1/320 ANA con patrón homogéneo, 3.200 mg de proteína en muestra de orina de 24 horas y anticuerpos antifosfolipídicos negativos. Se realizó diagnóstico de LESp con compromiso renal, neurológico y hematológico, decidiendo uso de metilprednisolona 1 g EV diario durante 3 días, para luego pasar a ciclofosfamida 1 g EV mensual por 6 meses. Después de 3 meses persisten proteinuria, fatiga y artralgias. Por este motivo, se decidió utilizar rituximab a una dosis de 375 mg / m2 en días 1 y 15 cada 6 meses. Tras 4 infusiones, la proteinuria desapareció, así como las artralgias y malestar general. Actualmente mantiene scores SLEDAI-2K en remisión, con dosis bajas de prednisona. Segundo caso: niño de 10 años, presentó dolor abdominal difuso con distensión asociada de inicio más o menos abrupto. Se agregó cansancio, dificultad para respirar y palpitaciones. Una radiografía simple de abdomen no mostró niveles hidroaéreos, pero la placa torácica demostró derrame pleural bilateral con agrandamiento de la silueta cardíaca. Un ecocardiograma y una ecografía abdominal reveló derrame pericárdico y ascitis respectivamente. Al examen físico se observó palidez general, edema translúcido de miembros inferiores, roce pericárdico y disminución del soplo vesicular en ambas bases pulmonares. Las pruebas de laboratorio mostraron leucopenia, linfopenia, anemia normocítica, reactantes de fase aguda elevados, ANA 1/560, anti-ADN 280 U / mL, complemento disminuido, transaminasas elevadas, urea y creatinina normales. Se diagnosticó LESp y se pulsó con metilprednisolona 30 mg / kg / dosis durante 4 días, para luego pasar a micofenolato 600 mg / m2 diarios. Inicialmente hubo mejoría, pero después de 2 meses reapareció la serositis inicial. Se decidió usar rituximab 375 mg / m2. Después de la segunda infusión la serositis desapareció, normalizándose valores de hemograma, complemento y transaminasas. Actualmente se encuentra en remisión, con dosis bajas de prednisona. Conclusión . Los casos presentados debutaron con infarto cerebral y serositis, mostraron ANA elevados títulos y disminución del complemento. Ambos casos mejoraron con rituximab tras el fracaso a ciclofosfamida y micofenolato. Se obtuvo el consentimiento informado de los padres y los pacientes.
Introduction . Pediatric systemic lupus erythematosus (pSLE) represents 15% of all SLE patients. Renal and neuropsychiatric involvement are more aggressive in pSLE, and single organ involvement is the most commonly found clinical form. Conditions such as cerebral infarction and serositis are unusual manifestation of pSLE. Therapy for pSLE is not different from that for the adult forms, and the therapy armamentarium is the same. Rituximab (RTX) is a worldwide used biological for SLE, with excellent results; however, there is still no consensus with respect to is real efficacy in pSLE. Objectives . Presentation of two pSLE cases with cerebral infarction and serositis as main characteristics, who did not respond to conventional therapy, but who did respond to RTX. Methods . Case report, describing the clinical presentation, diagnostic methods, and therapy approach used. Results . First case: This is a sixteen-year-old girl who was brought because of progressing headache and a tonic-clonic crisis. The brain CT scan showed a left frontoparietal cerebral infarction. Physical examination revealed livedo reticularis in both legs, joint pain, hair loss, and mouth ulcers. Laboratory tests revealed normocytic anemia, thrombocytopenia, reduced complement, 1/320 ANA with a homogeneous pattern, 3.200 mg 24-hour proteinuria, and negative anti-phospholipidic antibodies. A pSLE diagnosis was made, with renal, neurologic, and hematologic involvement, so it was decided to use methylprednisolone, 1 gram IV per day for three days, and then switch to cyclophosphamide 1 g IV per month for 6 months. After three months, proteinuria, fatigue, and arthralgia persisted. For this reason, it was decided to administer rituximab, 375 mg/m2 in days 1 and 15, every six months. After four infusions, proteinuria, joint pain and malaise all disappeared. Nowadays this patient maintains SLEDAI-K scores in remission, and she is also receiving low-dose prednisone. Second case: This is a ten-year-old boy, who presented with abrupt diffuse abdominal pain associated with (abdominal) distention. Other manifestations were tiredness, shortness of breath, and palpitations. A plain abdomen X-ray film did not show hydro-aerial levels, but the chest X-ray film showed bilateral pleural effusion, and enlarged cardiac silhouette. Cardiac ultrasonography and abdominal ultrasonography revealed pericardial effusion and ascites, respectively. Findings in physical examination showed pallor translucid edema of the legs, pericardial throbbing, and reduced respiratory sounds in both pulmonary bases. Laboratory tests revealed leukopenia, lymphopenia, normocytic anemia, elevated acute phase reactants, ANA 1/560, anti-DNA 280 U/mL, reduced complement, elevated transaminases, and normal urea and creatinine. pSLE was diagnosed, and therapy instituted was methylprednisolone 30 mg/Kg/dose for 4 days, then it was switched to mycophenolate 600 mg/m2 per day. There was improvement initially, but after two months, serositis reappeared. Then it was decided to start rituximab 375 mg/m2. After the second infusion, serositis disappeared, and CBC, complement, and transaminase values returned to normal. Nowadays the patient is in remission, and he is receiving low-dose prednisone. Conclusión . Both presented cases featured cerebral infarction and serositis. They also showed high ANA titers and reduced complement. Both patients improved their condition with rituximab after failure with cyclophosphamide and mycophenolate. Informed consent from both parents and patients was obtained.
RESUMO
Resumo A leucemia promielocítica aguda (LPA) é um subgrupo da leucemia mieloide aguda (LMA). Embora se saiba que as complicações hemorrágicas são comuns, as complicações trombóticas não são tão raras quanto se pensa. No entanto, infarto do miocárdio e incidência de acidente vascular cerebral isquêmico são muito raros durante a LMA. Aqui, apresentamos o caso surpreendente de LPA diagnosticada com pancitopenia em sua apresentação com infarto agudo do miocárdio e acidente vascular cerebral isquêmico.
Abstract Acute promyelocytic leukemia (APL) is a subgroup of acute myeloid leukemia (AML). Although it is known that hemorrhagic complications are common, thrombotic complications are not as rare as thought. However, myocardial infarction and ischemic stroke incidence are very rare during AML. Here, we present the astonishing case of APL diagnosed with pancytopenia in its presentation with acute myocardial infarction and ischemic stroke.
RESUMO
Introducción: el ACV constituye un problema de salud y la trombólisis sistémica una estrategia de reperfusión con alto nivel de evidencia para su tratamiento. Los reportes nacionales sobre su utilización son escasos. Objetivos: comunicar y analizar los resultados de esta terapia en el Hospital de Clínicas. Establecer predictores de buena evolución, hemorragia intracraneana y mortalidad. Métodos: estudio observacional analítico de los pacientes trombolizados en el Hospital de Clínicas (2010-2021). Resultados: se realizó trombólisis sistémica a 268 pacientes. La mediana del NIHSS al ingreso fue 12 puntos. Un 42% fueron infartos totales de la circulación anterior. La cardioembolia constituyó la etiopatogenia más frecuente. El 59,3% de los pacientes fueron externalizados con independencia funcional y 55,2% con déficit neurológico mínimo. Las tasas de hemorragia intracraneana sintomática y mortalidad fueron 7,1% y 18,7% respectivamente. El 57% de los pacientes se trataron con tiempo puerta aguja ≤60 minutos. El porcentaje de trombólisis en el total de ACV fue 18,9%. La edad, NIHSS al ingreso e internación en unidad de ACV se comportaron como variables importantes para predecir buena evolución, hemorragia intracraneana y muerte. Discusión y conclusiones: se comunicó la mayor casuística nacional sobre el tema. Los parámetros de efectividad y seguridad del tratamiento fueron comparables a los reportados internacionalmente. Se destacaron los buenos tiempos puerta aguja y tasa trombólisis sobre ACV totales como indicadores satisfactorios de calidad asistencial. La internación en unidad de ACV se comportó como un factor predictor de independencia funcional y protector frente a mortalidad hospitalaria.
Introduction: Strokes are a health problem and systemic thrombolysis constitutes a reperfusion strategy backed up by significant evidence on its positive therapeutic impact. National reports on its use are scarce. Objectives: To report and analyze results obtained with this therapeutic approach at the Clinicas Hospital. To establish predictive factors for a good evolution, intracranial hemorrhage and mortality. Method: Observational, analytical study of thrombolysed patients at Clinicas Hospital (2010-2021). Results: Systemic thrombolysis was performed in 268 patients. Average NIHSS score was 12 points when admitted to hospital.42 % of cases were total anterior circulation infarct (TACI). Cardioembolic ischaemmic stroke was the most frequent etiopahogenesis. 59.3% of patients were discharged with functional independence and 55.2% had minimal neurologic deficit. Symptomatic intracranial hemorrhage and mortality rates were 7.1% and 18.7% respectively. 57% of patients were assisted within ≤60 minutes they showed up at the ER. Thrombolysis percentage in total number of strokes was 18.9%. Age, NIHSS score upon arrival to hospital and admission to the stroke unit were significant variables to predict a good evolution, intracranial hemorrhage and death. Discussion and conclusions: The large number of cases in the country was reported. Effectiveness and safety parameters for this treatment were comparable to those reported internationally. The good door-to-needle time and thrombolysis rate versus total number of strokes stood out as satisfactory indicators of healthcare quality. Admission to the stroke unit behaved as a predictive factor of functional independence and it protected patients from hospital mortality.
Introdução: o AVC é um problema de saúde sendo a trombólise sistêmica uma estratégia de reperfusão com alto nível de evidência para seu tratamento. Os dados nacionais sobre seu uso são escassos. Objetivos: comunicar e analisar os resultados desta terapia no Hospital de Clínicas. Estabelecer preditores de boa evolução, hemorragia intracraniana e mortalidade. Métodos: estudo observacional analítico de pacientes trombolisados no Hospital de Clínicas (2010-2021). Resultados: a trombólise sistêmica foi realizada em 268 pacientes. A mediana do índice NIHSS na admissão foi de 12 pontos. 42% eram infartos totais da circulação anterior. A cardioembolia foi a etiopatogenia mais frequente. 59,3% dos pacientes tiveram alta da unidade com independência funcional e 55,2% com déficit neurológico mínimo. As taxas de hemorragia intracraniana sintomática e mortalidade foram de 7,1% e 18,7%, respectivamente. 57% dos pacientes foram tratados com tempo porta-agulha ≤60 minutos. A porcentagem de trombólise no AVC total foi de 18,9%. Idade, NIHSS na admissão e internação na unidade de AVC se comportaram como variáveis importantes para prever boa evolução, hemorragia intracraniana e óbito. Discussão e conclusões: este trabajo inclui a maior casuística nacional sobre o tema. Os parâmetros de eficácia e segurança do tratamento foram comparáveis aos descritos na bibliografia internacional. Foram destacados como indicadores satisfatórios da qualidade do atendimento os bons tempos porta-agulha e taxa de trombólise em relação ao AVC total. A internação em unidade de AVC comportou-se como preditor de independência funcional e protetor contra a mortalidade hospitalar.

RESUMEN INTRODUCCIÓN: La fibrilación auricular aumenta 5 veces el riesgo de un ataque cerebrovascular de origen cardioembólico. La anticoagulación está indicada para prevención primaria y secundaria de embolismo cerebral. En pacientes con alto riesgo de sangrado no modificable se ha propuesto el cierre de apéndice auricular izquierdo como alternativa a la anticoagulación. MÉTODOS: Serie de casos retrospectiva de pacientes incluidos en el registro ReACTIVE entre los años 2019 y 2020 con diagnóstico de fibrilación auricular, puntaje de CHA2DS2-VASc ≥ 4, HAS BLED ≥ 3 y contraindicación de terapia anticoagulante a largo plazo. Se incluyeron variables demográficas, factores de riesgo, desenlace clínico usando la escala de Rankin modificado y se hizo seguimiento clínico a 3 meses después del procedimiento. RESULTADOS: Se incluyeron 6 pacientes, el 50 % de ellos mujeres, con mediana de edad de 80,8 ± 4,8 años. El 83,3 % presentó antecedente de sangrado mayor bajo consumo de anticoagulantes. En el seguimiento a 90 días, ningún paciente experimentó sangrado ni ataque cerebrovascular, un paciente murió por causas no cardiovasculares, en tanto que el 83,3 % de los pacientes tuvieron un Rankin modificado favorable (0-2). CONCLUSIONES: El cierre de apéndice auricular es una opción terapéutica en pacientes con fibrilación auricular y contraindicación para anticoagulación por alto riesgo de sangrado. Nuestra serie obtuvo resultados similares a los publicados a escala nacional a pesar de incluir pacientes con edad más avanzada. La conformación de equipos interdisciplinarios de corazón y cerebro es útil en la selección de pacientes para esta terapia.
ABSTRACT INTRODUCTION: Atrial fibrillation increases the risk of a cerebrovascular attack of cardioembolic source by 5 times. Anticoagulation is indicated for primary and secondary prevention of cerebral embolism. In patients at high risk of non-modifiable bleeding, closure of the left atrial appendage has been proposed as an alternative to anticoagulation. METHODS: Retrospective case series of patients included in the ReACTIVE registry between 2019 and 2020 with a diagnosis of atrial fibrillation, CHA2DS2-VASc score ≥ 4, HAS-BLED ≥ 3, and long-term anticoagulant therapy contraindication. Demographic variables, risk factors, and clinical outcomes were included using the modified Rankin scale, and clinical follow-up was done three months after the procedure. RESULTS: 6 patients were included, 50 % women, median age 80.8 ± 4.8 years. 83.3 % history of major bleeding under anticoagulant treatment. At the 90-day follow-up, no patient had a bleeding or cerebrovascular attack, one patient died from non-cardiovascular causes, and 83.3 % of the patients had a favorable modified Rankin (0-2). CONCLUSIONS: Atrial appendix closure is a therapeutic option in patients with atrial fibrillation and a contraindication for anticoagulation due to a high risk of bleeding. Our series obtained results like those published at the national level despite including older patients. The formation of interdisciplinary heart and brain teams is helpful in the selection of patients for this therapy.

INTRODUCTION: Recent studies have reported an increasing incidence of ischaemic stroke among young adults. However, the strength of the association between traditional vascular risk factors has not been fully established. METHODS: We compared 120 patients with a first ischaemic stroke before the age of 55 years admitted to the stroke unit of our centre with 600 healthy non-stroke controls from a population-based cohort study (HERMEX), matched for sex. Risk factors assessed included: hypertension, obesity, auricular fibrillation, current smoking, estimated glomerular filtration rate (eGFR), total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides, high-density lipoprotein cholesterol (HDL-C) and diabetes mellitus. We used logistic regression analysis and calculated population attributable risk. We performed an overall analysis, by sex and aetiological subgroup. RESULTS: Using logistic regression analysis, we found that overall, the significant risk factors were: hypertension (OR: 1.58; 95%CI: 1.01-2.50), atrial fibrillation (OR: 4.77; 95%CI: 1.20-19.00), low eGFR (OR: 4.74; 95%CI: 1.3-21.94) and low HDL-C (OR: 5.20; 95%CI: 3.29-8.21), as well as smoking for males (OR: 1.86; 95%CI: 1.14-3.03). LDL-C showed an inverse association with stroke. The population attributable risk for HDL-C was 37.8% and for hypertension 21.1%. In terms of aetiological subgroups, only low HDL-C was associated with stroke of undetermined aetiology. CONCLUSIONS: Hypertension, auricular fibrillation, low eGFR, and low HDL-C, plus tobacco use in men, are the main risk factors among patients under 55 years of age with a first ischaemic stroke. We believe that it would be of particular interest to further explore the management of low HDL-C levels as part of preventive strategies in young stroke patients.
RESUMO
La enfermedad vascular cerebral (EVC) es una patología caracterizada por un déficit neurológico súbito, secundario a oclusión o ruptura de un vaso sanguíneo cerebral; se divide en isquémica o infarto cerebral (IC) y hemorrágica. La EVC es reconocida como la primera causa de discapacidad y la quinta causa de muerte en México, registrándose cerca de 170 mil casos nuevos al año. Existe amplia evidencia que demuestra una reducción en los desenlaces negativos, como muerte y discapacidad, al realizar intervenciones rápidas, incluyendo la administración de trombolisis intravenosa con rt-PA (activador tisular de plasminógeno recombinante) y trombectomía mecánica. La coordinación multidisciplinaria del equipo de salud y los cuidados efectivos de enfermería, son vitales durante todas las etapas de atención de la EVC. Esta revisión da a conocer un panorama general del manejo del infarto cerebral e identificar las intervenciones indispensables del profesional de enfermería realiza durante las etapas prehospitalarias, pretrombolisis, durante trombolisis y postrombolisis.
Cerebralvascular disease (CVD) is a pathology characterized by a sudden neurological deficit secondary to occlusion or rupture of a cerebral blood vessel; it is divided into ischemic or cerebral infarction (CI) and hemorrhagic. CVD is recognized as the first cause of disability and the fifth cause of death in Mexico, with nearly 170,000 new cases registered each year. There is ample evidence that shows a reduction in negative outcomes, such as death and disability, with rapid interventions, including the administration of intravenous thrombolysis with rt-PA (recombinant tissue plasminogen activator) and mechanical thrombectomy. Multidisciplinary coordination of the health care team and effective nursing care are vital during all stages of CVD care. This review provides an overview of the management of cerebral infarction and identifies essential nursing interventions during the prehospital, prethrombolysis, during thrombolysis, and postthrombolysis stages.

RESUMEN INTRODUCCIÓN: La enfermedad cerebrovascular y las demencias están unidas por el deterioro cognitivo y la demencia vascular. Se trata de condiciones de salud potencialmente prevenibles, capaces de generar discapacidad, especialmente en la población adulta mayor. METODOLOGÍA: El propósito de este trabajo es caracterizar el deterioro cognitivo vascular y el espectro de la demencia vascular esporádica, mediante una revisión de tema con énfasis neurocognitivo. RESULTADOS: Entre el 30 % y el 40 % de las personas con enfermedad cerebrovascular experimentan algún grado de compromiso cognitivo. Después de los tres meses de haber presentado una enfermedad cerebro-vascular, alrededor del 20 % al 30 % de los pacientes serán diagnosticados con demencia, y entre un 10 % y un 35 %, con deterioro cognitivo. El deterioro cognitivo vascular y la demencia vascular tienen una serie de factores comunes a la enfermedad cerebrovascular y a la enfermedad de Alzheimer. La demencia vascular presenta subtipos: la demencia multiinfarto, caracterizada por varios infartos cerebrales que se acumulan en el tiempo; la demencia por infarto estratégico, en la que hay infartos localizados en zonas cortico-subcorticales con gran conectividad; y la demencia por enfermedad isquémica de pequeñas arterias, producida por infartos lacunares o lesiones difusas de sustancia blanca, que afecta principalmente la velocidad de procesamiento y las funciones ejecutivas. CONCLUSIONES: El deterioro cognitivo en personas con enfermedad cerebrovascular involucra pérdidas en el rendimiento de una o varias funciones mentales superiores, situación que puede evolucionar hasta la demencia, en la que un déficit permanente en las funciones mentales afecta de manera importante el desempeño y el funcionamiento. Sin embargo, es un tema que permite hablar y promover activamente el control o la modificación de factores de riesgo cardiovascular.
ABSTRACT INTRODUCTION: Cerebrovascular disease and dementias are linked by cognitive impairment and dementia of vascular origin. Potentially preventable health conditions capable of generating disability, especially in the older adult population. METHODOLOGY: The purpose is to characterize the cognitive impairment of vascular origin and the spectrum of sporadic vascular dementia, through a review of the topic with a neurocognitive emphasis. RESULTS: Between 30 % to 40 % of people with cerebrovascular disease acquire some degree of cognitive impairment. After three months of having experienced a cerebrovascular disease, about 20 % to 30 % of patients will be diagnosed with dementia and between 10 % and 35 % with cognitive impairment. Vascular cognitive impairment and vascular dementia have several factors common to cerebrovascular disease and Alzheimer's disease. Vascular dementia has subtypes: multi-infarct dementia characterized by several cerebral infarcts that accumulate over time; dementia due to strategic infarction, where there are infarcts located in cortico-subcortical areas with great connectivity; and dementia due to ischemic disease of the small arteries, produced by lacunar infarcts or diffuse lesions of the white matter, which mainly affect processing speed and executive functions. CONCLUSIONS: Cognitive impairment in people with cerebrovascular disease involves losses in the performance of one or several higher mental functions, a situation that can evolve to dementia, where a permanent deficit in mental functions significantly affects performance and functioning. However, it is a topic that allows to speak and actively promote the control and / or modification of cardiovascular risk factors.

INTRODUCTION: Embolic stroke of undetermined source (ESUS) accounts for 25% of all cerebral infarcts; only 30% are associated with paroxysmal atrial fibrillation (AF). Various biochemical, electrocardiographic, and echocardiographic findings may suggest left atrial damage and increased risk of embolism in the absence of clinically documented AF or atrial flutter. In this review, we analyse the available evidence on atrial cardiopathy or atrial disease, its involvement in ESUS, and its identification through electrocardiographic, echocardiographic, and serum markers and its possible therapeutic implications. DEVELOPMENT: A systematic search was conducted on MEDLINE (PubMed) using the following MeSH terms: MeSH [ESUS]+[atrial cardiopathy]+[atrial fibrillation]+[interatrial block]+[treatment]. We selected what we considered to be the most useful original prospective or retrospective studies and systematic reviews. We then read the full texts of the articles and checked the references cited in each article. We analyse epidemiological and demographic variables of patients with ESUS, as well as recent evidence related to presentation and prognosis and factors associated with recurrence and mortality. We review the contribution of atrial cardiopathy diagnosis prior to the detection of AF and the clinical, electrocardiographic, and echocardiographic variables and the biochemical markers associated with its development and its potential contribution to cerebral embolism. CONCLUSIONS: The systematic search of biochemical and electrocardiographic, and echocardiographic alterations can be useful to identify ESUS patients at higher risk of recurrence.

Abstract In 2019, the American Heart Association did not recommend the emergent use of anticoagulation to prevent recurrence or progression of acute ischemic stroke. However, its indication in patients with extracranial artery intraluminal thrombus with artery-to-artery cerebral embolization must be analyzed. In this article, we will also discuss other indications of anticoagulation. This treatment could be indicated in patients with ischemic stroke caused by embolization from cervical artery dissection, catastrophic antiphospholipid antibodies syndrome (APS) and some cases of Covid 19. For secondary prevention, anticoagulation is recommended for Cardioembolic stroke such as nonvalvular atrial fibrillation and other cardiopathies, some patients with cervical artery dissection, stroke associated with cancer, and thrombophilia such as APS. The timing to restart anticoagulation after a large ischemic stroke or after a cerebral hemorrhagic transformation always represent a challenge. Even in patients with high risk of thromboembolism it should be delayed at least two weeks, ideal after four weeks.
Resumo Anticoagulação na fase aguda do acidente vascular isquêmico (AVCI) ainda é um tema bastante controverso. Em 2019, a American Heart Association (AHA) não recomendou o uso precoce da anticoagulação para evitar a progressão ou recorrência de AVCIs de grandes artérias. Mas sugere que a anticoagulação em pacientes com AVCI por embolização a partir de trombos intraluminais aderidos a parede de vasos extracranianos fosse analisada. Tanto a antiagregação como anticoagulação são opções terapêuticas nos casos de AVCI por dissecção arterial cervical. Mas em pacientes com AVCI por mecanismo de embolização, a anticoagulação poderia ser indicada. Pacientes com AVCI e sindrome catastrófica por anticorpos antifosfolípides devem ser anticoagulados além de receber tratamento específico. Outra indicação seriam casos de trombofilia como Covid 19. Nesse artigo de revisão será discutida a prevenção secundária de AVCI em situações específicas (AVCI cardioembólico em pacientes com fibrilação atrial não valvular ou outras cardiopatias, AVCI em casos oncológicos, além de outras trombofilias), além do período ideal para se introduzir ou reiniciar a anticoagulação após transformação hemorrágica.
RESUMO
Introducción: Las enfermedades Cerebrovasculares constituyen un importante problema de salud a escala global y en Cuba ocupan la tercera causa de muerte y la primera causa de discapacidad. Objetivo: Evaluar el uso de atorvastatina en el infarto cerebral aterotrombótico agudo. Métodos: Se realizó un estudio prospectivo longitudinal en los pacientes que acudieron al cuerpo de guardia del Hospital Clínico Quirúrgico Julio Trigo López diagnosticados como infarto cerebral aterotrombótico agudo. De forma aleatoria y con previo consentimiento informado se les suministró una dosis de 0, 20 mg o 40 mg de atorvastatina. Se les realizó tomografía axial computarizada de cráneo, la cual fue repetida al tercer día y a los 30 días. Se determinó el valor de proteína C reactiva en el cuerpo de guardia, y a los 30 días fueron evaluados clínicamente de acuerdo a la escala de National Institute of Health Stroke Scale en cuerpo de guardia, diariamente durante su ingreso y 30 días después. Resultados: El tamaño del área infartada disminuyó un 19,4 por ciento con 40 mg de atorvastatina al igual que el valor de proteína C reactiva que se redujo en 16 mg/L. La evaluación clínica según la escala de National Institute of Health Stroke Scale mostró una reducción en más de 8 puntos de acuerdo a la dosis de atorvastatina empleada. Conclusiones: Se demostró la eficacia de la atorvastatina por la disminución del área infartada, la reducción de los valores de proteína C reactiva y la evolución clínica favorable. Todos estos factores fueron directamente proporcional a la dosis de atorvastatina empleada(AU)
Introduction: Cererovascular diseases represent an important health problem worldwide and in Cuba they rank the third cause of death and the first cause of disability. Objective: To evaluate the use of astorvastin in acute atherotrombotic cerebral infactation. Methods: A longitudinal prospective study was carried out in patients who attended the emergency room of Julio Trigo López Surgical Clinical Hospital diagnosed with acute atherothrombotic cerebral infarction. Randomly and with prior informed consent, they were given a dose of 0, 20 mg or 40 mg of atorvastatin. Computerized axial tomography of the skull was performed, which was repeated on day 3 and day 30. The value of C-reactive protein in the emergency room was determined, and at day 30, they were clinically evaluated daily during admission and 30 days later, according to the scale of the National Institute of Health Stroke Scale in emergency room. Results: The size of the infarcted area decreased by 19.4 percent with 40 mg of atorvastatin, as well as the value of C-reactive protein, which decreased by 16 mg/L. The clinical evaluation according to the National Institute of Health Stroke Scale showed reduction of more than 8 points according to the dose of atorvastatin used. Conclusions: The efficacy of atorvastatin was demonstrated by the reduction of the infarcted area, the reduction of C-reactive protein values and the favorable clinical evolution. All of these factors were directly proportional to the dose of atorvastatin used(AU)

BACKGROUND: Advanced interatrial block (IAB) is an independent risk factor for ischaemic stroke. This study aimed to analyse whether advanced IAB predicts recurrence of embolic stroke of undetermined source (ESUS). METHODS: 104 patients with a confirmed diagnosis of ESUS were followed up for a median period of 15 months (interquartile range, 10-48). We recorded data on clinical variables, P-wave characteristics, and presence of IAB on the electrocardiogram. Electrocardiogram findings were interpreted by a blinded, centralised rater at (XXXX2). ESUS recurrence was the primary outcome variable. RESULTS: Median age was 47 years (range, 19-85); 50% of patients were women. IAB was detected in 36 patients (34.6%); IAB was partial in 29 cases (27.9%) and advanced in 7 (6.7%). Sixteen patients (15.4%) presented stroke recurrence; of these, 5 had partial and 4 had advanced IAB (P = .01; odds ratio [OR] = 9.44; 95% confidence interval [CI], 1.88-47.46; relative risk [RR] = 4.62; 95% CI, 2.01-10.61). Median P-wave duration was longer in patients with stroke recurrence (P = .009). The multivariate logistic regression analysis identified the following independent risk factors for stroke recurrence: advanced IAB (P < .001; OR = 10.86; 95% CI, 3.07-38.46), male sex (P = .028; OR = 4.6; 95% CI, 1.18-17.96), and age older than 50 years (P = .039; OR = 3.84; 95% CI, 1.06-13.88). In the Cox proportional hazards model, the risk variables identified were age older than 50 years (P = .002; hazard ratio, 7.04; 95% CI, 2.06-23.8) and P-wave duration (per ms) (P = .007; hazard ratio, 1.02; 95% CI, 1.01-1.04). CONCLUSIONS: Advanced IAB and age older than 50 years predict ESUS recurrence.
