- Cardiac obstruction secondary to metastatic invasion - A rare complication of Human Herpes Virus 8-positive plasmablastic lymphoma in acquired immunodeficiency syndrome(2012) PADUA, Daniele; RODRIGUES, Ana Clara; BARROS, Sergio; ARRUDA, Ana Lucia; CASTRO, Marianne; ANDRADE, Jose LazaroHuman herpes virus 8 (HHV8)-positive plasmablastic lymphoma (PBL) is a particularly rare and aggressive subtype of non-Hodgkin lymphoma, strongly associated with human immunodeficiency virus infection, with poor response to therapy and short survival. Characteristically, it shows proliferation of large plasmablastic cells with often eccentrically placed nuclei, with immunohistochemical assay positive for HHV8 latent nuclear antigen 1 and IgM. Primary mediastinal occurrence of a HHV8-positive PBL is rare and metastatic disease even more uncommon; tumor invasion to the heart leading to intracardiac obstruction with a rapidly fatal disease course has not been previously described.
conferenceObject SUBTLE IMPAIRMENT OF RIGHT VENTRICULAR FUNCTION IN SYSTEMIC SCLEROSIS WITH LUNG FIBROSIS DETECTED BY TISSUE DOPPLER(2014) SAMPAIO-BARROS, P.; RODRIGUES, A. C.; ROQUE, M.; ARRUDA, A. L.; BECKER, D.; BARROS, S.; KAY, F.; EMMERICH, T.; CERRI, G.- Lobar pulmonary perfusion quantification with dual-energy CT angiography: Interlobar variability and relationship with regional clot burden in pulmonary embolism(2022) LEE, Hye Ju; WANDERLEY, Mark; RUBIN, Vivian Cardinal da Silva; RODRIGUES, Ana Clara Tude; DINIZ, Amanda Rocha; PARGA, Jose Rodrigues; AMATO, Marcelo Britto PassosPurpose: Semi-automated lobar segmentation tools enable an anatomical assessment of regional pulmonary perfusion with Dual-Energy CTA (DE-CTA). We aimed to quantify lobar pulmonary perfusion with DE-CTA, analyze the perfusion distribution among the pulmonary lobes in subjects without cardiopulmonary diseases and assess the correlation between lobar perfusion and regional endoluminal clots in patients with acute pulmonary embolism (PE). Methods: We evaluated 151 consecutive subjects with suspected PE and without cardiopulmonary comorbidities. DE-CTA derived perfused blood volume (PBV) of each pulmonary lobe was measured applying a semi-automated lobar segmentation technique. In patients with PE, blood clot location was assessed, and CT-based vascular obstruction index of each lobe (CTOIlobe) was calculated and classified into three groups: CTOIlobe= 0, low CTOIlobe (1-50%) and high CTOIlobe (>50%). Results: Among patients without PE (103/151, 68.2%), median lobar PBV was 13.7% (IQR 10.2-18.0%); the right middle lobe presented lower PBV when compared to all the other lobes (p < .001). In patients with PE (48/151, 31.8%), lobar PBV was 12.6% (IQR 9.6-15.7%), 13.7% (IQR 10.1-16.7%) and 6.5% (IQR 5.1-10.2%) in the lobes with CTOIlobe= 0, low CTOIlobe and high CTOIlobe scores, respectively, with a significantly decreased PBV in the lobes with high CTOIlobe score (p < .001). ROC analysis of lobar PBV for prediction of high CTOIlobe score revealed AUC of 0.847 (95%CI 0.785-0.908).
article Assessment of Natriuretic Peptides: The Heart Should Be Evaluated as a Whole Reply(2014) RODRIGUES, Ana Clara Tude; VIEIRA, Marcelo Luiz Campos- Brain network dynamics characterization in epileptic seizures(2014) RODRIGUES, A. C.; MACHADO, B. S.; FLORENCE, G.; HAMAD, A. P.; SAKAMOTO, A. C.; FUJITA, A.; BACCALA, L. A.; AMARO JR., E.; SAMESHIMA, K.Here we propose and evaluate a new approach to analyse multichannel mesial temporal lobe epilepsy EEG data from eight patients through complex network and synchronization theories. The method employs a Granger causality test to infer the directed connectivity graphs and a wavelet transform based phase synchronization measure whose characteristics allow studying dynamical transitions during epileptic seizures. We present a new combined graph measure that quantifies the level of network hub formation, called network hub out-degree, which closely reflects the level of synchronization observed during the ictus.
