L.; Brito, Maria José; Martinho, Olga; Matos, Delcio; Carvalho, André LopesAntônio Talvane Torres de Oliveira and Céline Pinheiro contributed equally to the study ; Prova tipográfica (uncorrected proof) ; Monocarboxylate transporters (MCTs) have been described to play an important role in cancer, but to date there are no reports on the significance of MCT expression in gastrointestinal stromal tumors (GISTs). The aim of the present work was to assess the value of MCT expression, as ...
Lymphangiogenic VEGF-C and VEGFR-3 expression in genetically characterised gast...
Oliveira, Antônio Talvane Torres; Reis, R. M.; Afonso, Julieta; Martinho, Olga; Matos, Delcio; Carvalho, André Lopes; Vazquez, Vinícius LimaThis study aimed to assess the distribution of VEGF-C and VEGFR-3 expression in gastrointestinal stromal tumours (GISTs), and to analyse the value of lymphatic vessel density (LVD) in a tumour that is believed to preferentially metastasize through blood vessel conduits. A panel of immunohistochemical antibodies was used to evaluate 51 cases of genetically characterised GISTs: VEGF-C, VEGFR-3, D2-40 (for LVD ass...
Influência da idade e da doença colorretal na imunocompetência cutânea peri-col...
Salles,Valdemir José Alegre; Saad,Sarhan Sydney; Franco,Marcello Fabiano; Matos,Delcio; Martins,Marcos RobertoObjetivo: Caracterizar a resposta imunológica presente na camada dérmica da região peri-colostômica. Método: Foram incluídos quarenta e um doentes, portadores de colostomias realizadas há mais de oito semanas. Na determinação imuno-histoquímica foram avaliados os linfócitos Pan T, linfócito T - auxiliar, linfócito T - citotóxico, linfócito B, linfócito T - Natural Killer e os macrófagos. Resultados: Na análise ...
Acidose metabólica por hiperglicemia transitória pós enucleação de insulinoma p...
Apodaca-Torrez,Franz Robert; Goldenberg,Alberto; Saad,Sarhan Sydney; Lobo,Edson José; Triviño,TarcísioINTRODUÇÃO: Insulinoma é a neoplasia endócrina mais frequente dos tumores funcionantes do pâncreas. Origina-se a partir das células beta das ilhotas de Langerhans e caracteriza-se pela produção excessiva de insulina, com consequente hipoglicemia. O tratamento de escolha é a remoção cirúrgica da neoplasia. O presente relato tem como objetivo apresentar uma complicação metabólica pouco observada. RELATO DO CASO: ...
Ileostomy or colostomy for temporary decompression of colorectal anastomosis: s...
Güenaga,Katia Ferreira; Lustosa,Suzana Angélica Silva; Saad,Sarhan Sydney; Saconato,Humberto; Matos,DelcioPURPOSE: The controversy regarding whether loop ileostomy or loop transverse colostomy is a better method for temporary decompression of colorectal anastomosis motivated this review. METHODS: Five randomized trials were included, with 334 patients: 168 in the loop ileostomy group and 166 in the loop transverse colostomy group. The outcomes analyzed were: 1. Mortality; 2. Wound infection; 3. Time of stoma format...
Rubber band ligation and infrared photocoagulation for the outpatient treatment...
Ricci,Maurício Pichler; Matos,Délcio; Saad,Sarhan SydneyPURPOSE: To compare the results of rubber band ligation and infrared photocoagulation for the treatment of hemorrhoidal disease through the analysis of the incidence of complications after each treatment and respective success rate. METHODS: Forty-eight patients with first, second or third degree hemorrhoidal disease were randomized to recieve treatment with either rubber band ligation (n=23) or infrared photoc...
Assessment of staging, prognosis and mortality of colorectal cancer by tumor ma...
Jesus,Eliane C.; Matos,Delcio; Artigiani,Ricardo; Waitzberg,Angela F.L.; Goldenberg,Alberto; Saad,Sarhan SydneyPURPOSE: To evaluate the prognostic significance and correlation with staging and degree of cell differentiation of the tumoral expression of the proteins c-erbB-2 and E-cadherin, in patients with colorectal adenocarcinoma. METHODS: The study included 117 patients with an average age of 63.1 years and an average follow-up duration of 28.1 months. The disease-free interval, survival, incidence of recurrence and ...
Analysis of the correlation between p53 and bcl-2 expression with staging and p...
Lustosa,Suzana Angelica Silva; Logullo,Angela; Artigiani,Ricardo; Saad,Sarhan Sydney; Goldenberg,Alberto; Matos,DelcioPURPOSE: To analyze the correlation between p53 and bcl-2 expression and colorectal adenocarcinoma staging and prognosis. METHODS: This was a retrospective series of 125 colorectal adenocarcinoma patients (67 women and 58 men; ages 30-87 years) who underwent surgery with curative intent. The mean follow-up was 28.5 months (range: 2-96 months). TNM staging, tumor recurrence, survival and cancer-related mortality...
Estudo clínico comparativo entre anastomose colocólica com anel anastomótico bi...
Saad,Sarhan Sydney; Matos,DelcioA anastomose com sutura é método consagrado, apresentando desvantagens teóricas representadas pelo trauma tecidual, edema e alteração da microcirculação. Além disso, o fio de sutura, sendo corpo estranho, determina reação inflamatória, propiciando a aderência e a proliferação de bactérias, assim como de células neoplásicas que seriam evitadas ao se usar método de anastomose sem sutura. A procura por método de a...
