RESUMO
La enfermedad por coronavirus (COVID-19) producida por el SARS-CoV-2 ha sido un reto para los servicios de salud en todo el mundo. La pandemia se ha extendido ampliamente con más de 80 millones de casos confirmados y más de un millón de muertes a nivel mundial, por lo que ha estado bajo constante investigación para entender todos los aspectos de la enfermedad. Recientemente se han reportado varios casos de pacientes con síndrome de Guillain-Barré asociado a COVID-19 como manifestación principal, convirtiéndola en la primera enfermedad neurológica autoinmune desencadenada por SARS-CoV-2; sin embargo, es necesario obtener más información para entender completamente los mecanismos inmunopatogénicos implicados en esta asociación.
The coronavirus disease (COVID-19) caused by SARS-CoV-2 has been a challenge for health services around the world. The pandemic has spread widely, with more than 80 million confirmed cases and more than one million deaths globally. There have been many studies to understand all aspects of the disease. Recently, several cases have been reported of patients with Guillain-Barré syndrome associated with COVID-19 as the main manifestation. As it may be one of the first autoimmune neurological diseases triggered by SARS-CoV-2, it is necessary to obtain more information to fully understand the immunopathogenic mechanisms involved in this association.

Introduction: Intraoperative Radiotherapy (ioRT) is an emerging treatment option in oncologic surgery for various diseases including intraaxial brain lesions to improve surgical outcome and accelerate the adjuvant oncologic therapy. Despite its use in glioma surgery, the application and data regarding ioRT in the treatment of brain metastases (BMs) is sparse. Here were report the largest series of supratentorial BMs treated with resection and ioRT according to functional outcome and adverse events. Methods: We performed a retrospective chart review analysis of patients undergoing surgery for BMs following an interdisciplinary tumor board decision in every case with ioRT at our institution. Patient properties, functional status (Karnofsky Performance Score/KPS) before and after surgery as well as oncologic (disease, recursive partitioning analysis, lesion size) and operative parameters were analyzed until hospital discharge. Adverse events (AE) were recorded until 30 days after surgery and rated according to the Clavien Dindo Grading (CDG) scale. Results: 70 patients (40 female) with various oncologic diseases were identified and analyzed. Six underwent prior RT. Mean age was 66 ± 11 years. Preoperative median KPS was 80% with a mean BM volume of 3.2 ± 1.2â cm3. Nine patients (13%) experienced in total 14 AEs, including 2 cases (3%) of postoperative death (CDG5) and 2 with new postoperative epilepsy necessitating additional pharmacotreatment (CDG2). Five patients suffered from new neurologic deficit (CDG1) not needing further surgical or medical treatment. After surgery, the neurological status in 7 patients (10%) deteriorated while it improved in 21 cases (30%). Patients experiencing AEs had longer hospitalization and poorer postoperative KPS mdn. 90 vs. 80%. There was no statistically significant deterioration of the functional status during the immediate postoperative course in the whole patient cohort. Conclusion: Surgery for supratentorial BMs with ioRT seems safe and feasible. Further studies on the benefit regarding oncologic outcome need to be performed.
RESUMO
ABSTRACT The coronavirus disease 2019 (COVID-19) produced by SARS-CoV-2 has taken on great importance in recent months, and is under constant investigation by different areas of medicine, including rheumatology, in search of the best scientific evidence. In the case of the pediatric population, it is particularly important as it was first thought that the impact of the pan-demic in this population would be less due to the low presence of severe cases. Evidence is now being reported of clinical pictures in children with a diagnosis of COVID-19 who are characterized by an altered inflammatory state consisting of a storm of pro-inflammatory cytokines that produces manifestations similar to those presented in autoimmune diseases, such as Kawasaki disease. It has been called Multisystemic Inflammatory Syndrome in children, temporarily associated with SARS-CoV-2 which, in many cases requires hospitalization in pediatric intensive care units and multidisciplinary management by various specialties.
RESUMEN La enfermedad por coronavirus 2019 (COVID-19), producida por el SARS-CoV-2, ha tomado una gran importancia en los últimos meses y se encuentra bajo constante investigación por distintas áreas de la medicina, incluida la reumatología, en la búsqueda de la mejor evidencia científica. En el caso de la población pediátrica cobra especial importancia puesto que en un principio se pensaba que el impacto de la pandemia en esta población sería menor, debido a la baja presencia de casos severos, pero la evidencia actual reporta la existencia de cuadros clínicos en niños con diagnóstico de COVID-19 que se caracterizan por un estado inflamatorio alterado consistente en una tormenta de citocinas proinflamatorias que produce manifestaciones similares a las presentadas en enfermedades autoinmunes como la enfermedad de Kawasaki. Se le ha denominado síndrome inflamatorio multisistémico en ninos asociado temporalmente con SARS-CoV-2, el cual en muchos casos precisa internación en unidades de cuidados intensivos pediátricos y el manejo multidisciplinario por diversas especialidades.
