Acute pulmonary embolism (PE) is a leading cause of morbidity and mortality in the United States. PE associated with right ventricular strain, termed submassive or intermediate-risk PE, is associated with an increased rate of clinical deterioration and short-term mortality. Trials have demonstrated systemic thrombolytics may improve patient outcomes, but they carry a risk of major hemorrhage. Catheter-directed thrombolysis (CDT) may offer similar efficacy to and a lower risk of catastrophic hemorrhage than systemic thrombolysis. Three prospective trials have evaluated CDT for submassive PE; ULTIMA, SEATTLE II, and PERFECT. These trials provide evidence that CDT may improve radiographic efficacy endpoints in submassive PE with acceptable rates of major hemorrhage. However, the lack of clinical endpoints, long-term follow-up, and adequate sample size limit their generalizability. Future trials should be adequately powered and controlled so that the short- and long-term effectiveness and safety of CDT can be definitively determined.

Meta-analysis supports moderate sensitivity and excellent specificity of quantitative enhancement in the corticomedullary phase for differentiating papillary RCC from other tumors. The accuracy of combining enhancement and T2 signal-intensity characteristics merits further evaluation as a potential aid for management decisions.

Pensador dos mais instigantes da atualidade, Giorgio Agamben explora, em boa parte de seus ensaios filosóficos, a significação excepcional que apresenta Auschwitz para a compreensão de nossa modernidade esclarecida, significação esta que Adorno foi um dos primeiros a acusar. Sob o pano de fundo dessa convergência temática existente entre os dois pensadores, empreende-se aqui uma apreciação das críticas que Agamben endereça à filosofia de Adorno. Seria justo recriminar a dialética negativa adorniana por não ter sido capaz de se libertar do pendor idealista da dialética hegeliana? Seria justo censurá-la por ter sucumbido a uma espécie de estetização do messianismo, como sentencia Agamben? Essas questões são respondidas em defesa de Adorno.
Giorgio Agamben is, nowadays, one of the most intriguing thinkers. In a great extent of his philosophical essays he exploits the exceptional signification of Auschwitz for the understanding of our clarified modernity, and whose signification Adorno was one of the first to accuse. Under the background of such thematic convergence which is between the two thinkers, here we evaluate Agamben's criticisms of Adorno's philosophy. Would it be fair to condemn the Adornian negative dialectics because it could not get rid of the idealistic tendency of Hegelian dialectics? Would it be fair to censor it for having succumbed to a sort of aesthetic bias of messianism, as Agamben claims? Such questions are answered in defense of Adorno
