  2. Avaliação do risco cirúrgico nos doentes com cancro colo-rectal: POSSUM ou ACPGBI

    Goulart, A; Martins, S
    Introduction: Several models have been developed with the purpose of predicting surgical risk of patients submitted to colorectal cancer surgery. However, to date, there isn’t any model that fulfills this purpose in a satisfactory manner. Methods: We consulted the clinical processes of 345 patients, who were submitted to surgical colorectal cancer treatment at the General Surgery department in Hospital de Braga, and calculated surgical risk based on the following risk assessment scales: Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM), Portsmouth POSSUM (P-POSSUM), ColoRectal POSSUM (CR-POSSUM), Association of Coloproctology of Great Britain and Ireland (ACPGBI) and modified ACPGBI. For all...

  3. Prevalência do Síndrome de Frey após Parotidectomia

    Goulart, A; Soares, V; Koch, P
    Introduction: Frey’s syndrome is characterized by facial sweating, flushing and heat sensation in the parotid area. Its prevalence is highly variable. Methods: The present study included 33 selected patients, submitted to superficial parotidectomy. To the included patients, a clinical interview was conducted and Minor’s test, for objective evaluation of Frey’s syndrome, was applied. The degree of Frey’s syndrome severity was determined according to Luna Ortiz’s model and by using a 0-10 numeric scale. Results: Of the 33 initially selected patients, only 27 (81,8%) showed up for assessment at Hospital de Braga. Of the seven patients who referred sweating, only one classified it as “excessive”, giving...

    Martins, SF; Reis, RM; Mesquita-Rodrigues, A; Baltazar, F; Filho, AL
    Colorectal cancer (CRC) is one of the cancer models and most of the carcinogenic steps are presently well understood. Therefore, successful preventive measures are currently used in medical practice. However, CRC is still an important public health problem as it is the third most common cancer and the fourth most frequent cause of cancer death worldwide. Nowadays, pathologic stage is a unique and well-recognized prognostic indicator, however, more accurate indicators of the biologic behavior of CRC are expected to improve the specificity of medical treatment. Angiogenesis plays an important role in the growth and progression of cancer but its role...

  12. Increased expression of monocarboxylate transporters 1, 2, and 4 in colorectal carcinomas

    Pinheiro, C; Longatto-Filho, A; Scapulatempo, C; Mesquita-Rodrigues, A; Alves, VA; Schmitt, F; Baltazar, F
    Tumour cells are known to be highly glycolytic, thus producing high amounts of lactic acid. Monocarboxylate transporters (MCTs), by promoting the efflux of the accumulating acids, constitute one of the most important mechanisms in the maintenance of tumour intracellular pH. Since data concerning MCT expression in colorectal carcinomas (CRC) are scarce and controversial, the present study aimed to assess the expressions of MCT1, 2, and 4 in a well characterized series of CRC and assess their role in CRC carcinogenesis. CRC samples (126 cases) were analyzed for MCT1, MCT2, and MCT4 immunoexpression and findings correlated with clinico-pathological parameters. Expression of...

  17. Giant recurrent retroperitoneal liposarcoma initially presenting as inguinal hernia: Review of literature.

    Leão, P; Vilaça, S; Oliveira, M; Falcão, J
    INTRODUCTION: Liposarcomas comprise around 15% of soft tissue tumors. These tumors of mesodermal origin arise as single tumors, present one histologic type and diverse locations (including the retroperitoneum). Diagnosis of liposarcomas of retroperitoneum is difficult because of this unspecific presentation and in 50-100% of the cases there is recurrence from residual tissue. PRESENTATION OF CASE: An 86 year old male patient was admitted in 1996 due to a right and voluminous inguinal hernia. During the herniaplasty, a right paratesticular tumor was isolated and removed. The histologic exam revealed a well-differentiated liposarcoma. A CT scan was performed and a large abdominal mass was detected. The patient underwent a laparotomy and an incomplete...
