ABSTRACT

INTRODUCTION: Atrial fibrillation is responsible for a considerable number of cases of cardioembolism, accounting for 17% to 30% of the etiologies of all strokes. The software known as Stroke Risk Analysis (SRA) detects patients at high risk of paroxysmal atrial fibrillation by analyzing a continuous electrocardiogram recorded over different periods of time. OBJECTIVES: This article aims to carry out a systematic review investigating the effectiveness of the SRA method in predicting the risk of stroke patients having paroxysmal atrial fibrillation as the cause of the event. METHODS: The methods correspond to the format of the International Prospective Register of Systematic Reviews Protocol, according to CRD Identification Code: CRD42021253974. A systematic search was carried out in BMJB, PubMed/MEDLINE, Science Direct and LILACS. Six cohort studies met the inclusion criteria, representing a total of 2,088 participants with stroke, and compared the detection of patients with paroxysmal atrial fibrillation on the continuous recording electrocardiogram with a time variation of 1 to 48h with the use of SRA. RESULTS: Studies have shown that SRA has a high negative predictive value (between 96 and 99.1%) and can contribute to the selection of patients at high risk of paroxysmal atrial fibrillation to be referred for implantable cardiac monitoring to continue the investigation. CONCLUSIONS: A sequential combination of SRA with implantable cardiac monitoring is a promising strategy for detecting undiagnosed paroxysmal atrial fibrillation. Thus, the SRA can act as a cost-effective pre-selection tool to identify patients at higher risk of having paroxysmal atrial fibrillation as a possible cause of stroke and who may benefit from implantable cardiac monitoring. However, the lack of randomized studies is a limitation that must be considered.

ABSTRACT

O coriocarcinoma ovariano não gestacional é uma apresentação rara de câncer de ovário, acometendo principalmente mulheres pré-púberes. É considerada uma neoplasia agressiva, sendo comum a ocorrência de expansão para o pulmão em cerca de 80% dos pacientes, como no caso a seguir. Relato do caso: Sexo feminino, 12 anos de idade, com sangramento vaginal e distensão abdominal prolongados. A tomografia computadorizada mostrou volumosa massa heterogênea predominantemente cística e múltiplos septos grosseiros de permeio. Dosagem do beta-HCG de 49.929,81 mUI/ml. Foi submetida à laparotomia mediana para estadiamento, com anexectomia esquerda mais ressecção do tumor retroperitoneal e do omento, identificando-se estádio IV. O exame histopatológico concluiu ser um tumor de células germinativas do ovário constituído por coriocarcinoma não gestacional. Após alta hospitalar, foi submetida a sessões de quimioterapia. Posteriormente, apresentou em exames de imagem nódulos em ambos os pulmões, além de formações expansivas distribuídas no parênquima hepático. Nesse contexto, foi realizada metastectomia pulmonar meses depois. Após isso, novos exames de imagem foram realizados para o reestadiamento da doença. Foram encontrados alguns nódulos pulmonares residuais e, na ressonância magnética de crânio, sinais de hemorragia crônica. A evolução da paciente não foi favorável, havendo agravamento do estado geral e óbito um ano após o diagnóstico. Conclusão: Compreende-se, desse modo, a agressividade dessa doença, em especial na faixa pediátrica feminina, uma vez que a metástase precoce ocorre em uma porcentagem significativa dos casos, levando a um prognóstico desfavorável


Non-gestational ovarian choriocarcinoma is a rare form of ovarian cancer, mainly affecting prepubertal women. It is considered an aggressive neoplasm and expansion to the lung is common in around 80% of patients, as in the following case. Case report: Female, 12 years old, with prolonged vaginal bleeding and abdominal distension. Computed tomography showed a large heterogeneous mass, predominantly cystic, with multiple coarse septa. The beta HCG level was 49,929.81 mUI/ml. She underwent median laparotomy for staging, with left adnexectomy plus resection of the retroperitoneal tumor and omentum, identifying stage IV. The histopathological examination concluded that it was a germ cell tumor of the ovary consisting of non-gestational choriocarcinoma. After being discharged from hospital, she underwent chemotherapy sessions. Subsequently, imaging showed nodules in both lungs, as well as expansive formations distributed in the liver parenchyma. In this context, pulmonary metastasectomy was performed months later. After this, new imaging tests were carried out to restage the disease and the following findings were seen: some residual pulmonary nodules and on the MRI of the skull, a sign of chronic hemorrhage. The patient's evolution was not favorable, her general condition worsened and she died one year after diagnosis. Conclusion: The aggressiveness of this disease is clear, especially in female pediatric patients, since early metastasis occurs in a significant percentage of cases, leading to an unfavorable prognosis.


El coriocarcinoma ovárico no gestacional es una presentación poco frecuente del cáncer de ovario, que afecta principalmente a mujeres prepúberes. Se considera una neoplasia agresiva y la expansión al pulmón es frecuente en alrededor del 80% de las pacientes, como en el caso siguiente. Informe del caso: Mujer de 12 años con hemorragia vaginal prolongada y distensión abdominal. La tomografía computarizada mostró una gran masa heterogénea, predominantemente quística, con múltiples septos gruesos. El nivel de beta HCG era de 49 929,81 mUI/ml. Se le practicó una laparotomía media para la estadificación, con anexectomía izquierda más resección del tumor retroperitoneal y del epiplón, identificándose un estadio IV. El examen histopatológico concluyó que se trataba de un tumor germinal de ovario consistente en un coriocarcinoma no gestacional. Tras el alta hospitalaria, se sometió a sesiones de quimioterapia. Posteriormente, el diagnóstico por imagen mostró nódulos en ambos pulmones, así como formaciones expansivas distribuidas en el parénquima hepático. En este contexto, meses más tarde se le practicó una metastasectomía pulmonar. Tras ésta, se realizaron nuevas pruebas de imagen para reestadificar la enfermedad y se observaron los siguientes hallazgos: algunos nódulos pulmonares residuales y, en la resonancia magnética del cráneo, una señal de hemorragia crónica. La evolución de la paciente no fue favorable, su estado general empeoró y falleció un año después del diagnóstico.Conclusión: Por lo tanto, es comprensible la agresividad de esta enfermedad, especialmente en las mujeres pediátricas, ya que en un porcentaje significativo de casos se producen metástasis tempranas, lo que conlleva un pronóstico desfavorable
