Prosthetic valve thrombosis (PVT) is a rare but serious entity. Its diagnosis and treatment can be challenging and mortality remains high regardless of its management. A 50-year-old man admitted with cardiac arrest, whose physical examination and echocardioscopy suggested PVT confirmed with fluoroscopy. Intra-aortic fibrinolysis was the treatment chosen with successful results.

Object: Brain invasion is unusual in patients with paranasal sinuses cancer. Staging systems do not specify brain invasion extension who has an impact in therapeutic strategy and prognosis. Surgical series of this patient treated by endonasal endoscopic approach are scarce. In this paper, a novel classification and surgical strategy is proposed. Methods: A retrospective review of patients with ethmoidal malignant tumors with brain invasion treated at the National Institute of Oncology and Radiobiology from January 2015 to October 2017 by means endonasal endoscopic surgery was performed. All medical records were reviewed for demographics, diagnoses, presentation, endoscopic approach, reconstructive techniques and clinical outcomes. Pattern of brain invasion was classified in five grades. Chi-squared test, ANOVA test and Kaplan-Meier curves were used. Results: Forty-seven patients (26 males and 21 females) were registered. Mean age was 52.3 years ± 27.0. Only 3 patients presented with neurologic symptoms. Histologic subtypes were squamous cell carcinoma (25 patients), adenocarcinoma (16 patients), and esthesioneuroblastoma (6 patients). Five patients corresponded to Grade I, 39 Grade II and 3 Grade III. The mean surgical time was 351.9 min (±45). The mean blood loss was 704.5 ml (±206). The mean ICU stay was 1.1 (ranging from 1 to 2 ) days and the hospital stay was 5.3 (ranging from 5 to 7) days. Conclusions: Brain invasion represents a particular therapeutic challenge in patients with malignant nasosinusal tumors. Surgical treatment is possible in some cases, including endonasal endoscopic approach. A stage classification of brain invasion helps to establish an optimal surgical strategy and a prognosis.

本文应用一种综合概念框架——MIRABEL——对由环境变化对生物多样性引起的后果进行了分析,我们在此讨论了这一模型的方法和其中的部分结果。文章就欧洲28个国家对所预测的因10类环境压力造成的受胁迫生境的地位变化用MIRABEL模型进行了列表显示。通过对13个生态区域中的每一个区域编制单独的影响表格,对在压力和影响严重的情况下区域的变化进行了研究。结果表明,农业集约化是主要的威胁因子之一。通过MIRABEL记载,证明欧洲不同生态地区的压力强度、其变化速率以及过去和将来对生物多样性的影响差异,与欧洲生物地理变异有关,这就要求我们在评价环境变化时需要将这些差异性考虑在内。
