  1. On the utility of 3D hand cursors to explore medical volume datasets with a touchless interface.

    Lopes, S; Parreira, F; Paulo, F; Nunes, V; Rego, A; Neves, C; Rodrigues, S; Jorge, A
    Analyzing medical volume datasets requires interactive visualization so that users can extract anatomo-physiological information in real-time. Conventional volume rendering systems rely on 2D input devices, such as mice and keyboards, which are known to hamper 3D analysis as users often struggle to obtain the desired orientation that is only achieved after several attempts. In this paper, we address which 3D analysis tools are better performed with 3D hand cursors operating on a touchless interface comparatively to a 2D input devices running on a conventional WIMP interface. The main goals of this paper are to explore the capabilities of (simple) hand...

  2. Single-cell functional and chemosensitive profiling of combinatorial colorectal therapy in zebrafish xenografts.

    Fior, R; Póvoa, V; Mendes, V; Carvalho, T; Gomes, A; Figueiredo, N; Ferreira, G
    Cancer is as unique as the person fighting it. With the exception of a few biomarker-driven therapies, patients go through rounds of trial-and-error approaches to find the best treatment. Using patient-derived cell lines, we show that zebrafish larvae xenotransplants constitute a fast and highly sensitive in vivo model for differential therapy response, with resolution to reveal intratumor functional cancer heterogeneity. We screened international colorectal cancer therapeutic guidelines and determined distinct functional tumor behaviors (proliferation, metastasis, and angiogenesis) and differential sensitivities to standard therapy. We observed a general higher sensitivity to FOLFIRI [5-fluorouracil(FU)+irinotecan+folinic acid] than to FOLFOX (5-FU+oxaliplatin+folinic acid), not only...

  4. Abdominal tuberculosis: an old disease surprising young doctors.

    Sousa, M; Batista, J; Pacheco, P; Nunes, V
    Tuberculosis remains a worldwide public health concern. Atypical extrapulmonary presentations may delay the diagnosis and treatment. We present the case of an adult woman admitted to the emergency department with bowel obstruction. The putative intraoperative diagnostic hypothesis was ovarian cancer with peritoneal dissemination. Histopathological analysis showed a chronic granulomatous inflammatory disease with acid-fast bacilli. The patient was started on an alternative parenteral antituberculosis drug combination until oral feeding was available. Currently, 5 months after surgery, she is asymptomatic. Abdominal tuberculosis is the most frequent extrapulmonary site with a wide range of clinical presentations. Emergency laparotomy may be necessary in patients who...

  5. Retalho V-Y bilateral para reconstrução do períneo após amputação abdomino-perineal extraelevadora

    Rocha, R; Carneiro, C; João, A; Soares, A; Aparício, D; Fragoso, M; Marinho, R; Sousa, M; Leichsenring, C; Geraldes, V; Nunes, V
    A descrição da amputação abdominoperineal extraelevadora (ELAPE) para a ressecção de tumores do recto baixo ou da margem anal, a subsequente estandardização do tempo perineal e a definição das suas indicações precisas, veio colocar enfâse particular na necessidade de recorrer a técnicas de reconstrução do períneo para encerramento dos defeitos perineais provocados por ressecções mais alargadas. Apresentamos um caso de ELAPE por carcinoma pavimento-celular (CPC) da margem do ânus com necessidade de reconstrução do períneo com retalho miocutâneo V-Y bilateral e revemos a literatura quanto às opções existentes e respetivas vantagens, desvantagens e evidência existente.

  6. Excisão completa do mesocólon – revisão da literatura

    Carneiro, C; Rocha, R; Marinho, R; Gomes, A; Leichsenring, C; Geraldes, V; Nunes, V
    Desde a descrição da Excisão Total do Mesorreto (TME), a taxa de recidiva local da neoplasia do recto desceu de 20 a 40% para cerca de 10%(1,2). É neste contexto, que Hohenberger descreve em 2008 a Excisão Completa do Mesocólon (Complete Mesocolic Excision, CME)(3). Trata-se de uma técnica cirúrgica mais radical, tendo como base teórica e conceptual os mesmos princípios descritos por Heald para a TME. Com a CME estão descritas taxa de recidiva locorregional de 3,6% e sobrevida global aos 5 anos de 89%, resultados substancialmente melhores que os relatados na literatura utilizando a técnica convencional. Foi efetuada uma revisão da literatura com o...

  10. Impact of bowel resection margins in node negative colon cancer.

    Rocha, R; Marinho, R; Aparício, D; Fragoso, M; Sousa, M; Gomes, A; Leichsenring, C; Carneiro, C; Geraldes, V; Nunes, V
    Surgical intestinal resection margins in colon cancer are a longstanding debate in terms the optimal distance between the tumor and the colonic section line. The aim of this study is to define the oncological outcomes in relation to surgical margins, measured in terms or recurrence rate, time-to-recurrence, disease-free survival and overall survival in a population of node negative colon cancer patients. METHODS: We conducted a retrospective observational longitudinal single institution study. All patients submitted to colon cancer surgery between January 2006 and December 2010 were analyzed. Only node negative patients were included in the study, with analysis of 215 patient charts, divided...

  12. High-risk features in potentially resectable colon cancer: a prospective MDCT-pathology agreement study

    Santiago, I; Rodrigues, E; Germano, A; Costa, A; Manso, R; Gomes, A; Leichsenring, C; Geraldes, V
    Neoadjuvant chemotherapy in potentially resectable high-risk Stage II and Stage III colon cancer has demonstrated promising results in the PRODIGE 22-ECKINOXE Phase II trial. Identification of adverse morphologic features, namely T3 with >5 mm extramural extension/T4 stages and/or N2, is fundamental and requires accurate noninvasive imaging. Our aim was to assess the value of optimized preoperative MDCT to stratify potentially resectable colon cancer patients for neoadjuvant therapy. METHODS: this is an observational prospective cross-sectional radiologic-pathologic agreement study. All patients with colon cancer referred to our Institution's Radiology department for preoperative MDCT staging between 01-10-2013 and 11-02-2015 underwent independent reading based on axial...

  15. Colheita de córneas no Hospital Fernando Fonseca: o potencial e a realidade

    Gomes, A; Fernandes, A; Batista, A; Fernandes, AP
    Introdução: A disponibilidade de córneas para transplante continua a ser um fator limitante na resposta terapêutica a muitos doentes com patologia de córnea. A operacionalização do programa de colheita e transplante de córneas no Hospital Prof. Doutor Fernando Fonseca, EPE (HFF) teve início em 2012 e desde então tem sido preocupação do núcleo de Coordenação Hospitalar de Doação (NCHD) a otimização do número de colheitas respeitando os padrões de qualidade definidos pela legislação. Metodologia: Os autores apresentam uma análise retrospetiva de todos os óbitos ocorridos no HFF no ano de 2014, aplicando os critérios de seleção demográficos e clínicos bem...

  18. An ontogenetic approach to gynecologic malignancies

    Santiago, I; Gomes, A; Heald, R
    Ontogenetic anatomy is the mapping of body compartments established during early embryologic development, particularly well demarcated in the adult pelvis. Traditional cancer surgery is based on wide tumour excision with a safe margin, whereas the ontogenetic theory of local tumour spread claims that local dissemination is facilitated in the ontogenetic compartment of origin, but suppressed at its borders in the early stages of cancer development. Optimal local control of cancer is achieved by whole compartment resection with intact margins following ontogenetic "planes". The principles embodied in this hypothesis are most convincingly supported by the results of the implementation of total...

  19. Spontaneous Rupture of Pancreatic Pseudocyst: Report of Two Cases.

    Rocha, R; Marinho, R; Gomes, A; Sousa, M; Pignatelli, N; Carneiro, C; Nunes, V
    Introduction. Pancreatic pseudocysts are a common complication of acute pancreatitis. Pancreatic pseudocyst's natural history ranges between its spontaneous regression and the settlement of serious complications if untreated, such as splenic complications, hemorrhage, infection, biliary complications, portal hypertension, and rupture. The rupture of a pancreatic pseudocyst to the peritoneal cavity is a dangerous complication leading to severe peritonitis and septic conditions. It requires emergent surgical exploration that is often of great technical difficulty and with important morbidity and mortality. Case Study. We present two cases of spontaneous rupture of pancreatic pseudocysts, managed differently according to the local and systemic conditions. Conclusion....
