Abstract: the use of suture in anastomosis presents some theoretical disadvantages that they would be avoided by using sutureless intestinal anastomosis. the biofragmentable ring idealized by hardy et al.(1985), is composed by polyglycolic acid and barium sulfate. it is constituted by two identical components that are coupled, not returning to the original position after its occlusion. this ring suffers desintegration in 2 to 3 weeks, and is eliminated with evacuation. this device allows a sutureless anastomosis by the compression of intestinal walls. the purpose of this prospective and randomized study was to compare the clinical and endoscopic results in eletive and low risk colonic anastomosis accomplished with biofragmentable anastomosis ring and with non absorbable suture. material: thirty-six patients were stratified in two groups of 18 that were denominated group i (biofragmentable anastomosis ring) and group ii (non absorbable suture). the average age for group i was 36 years and for group ii was 42. the most frequent surgical indication in both groups was reconstruction of the intestinal flow after colostomy. all patients were submitted to biochemical blood tests, nutritional and surgical risk evaluation. the statistical analysis used for comparison between groups demonstrated that they were homogeneous. results: comparative analysis of the intraoperative period parameters revealed that the anastomosis with biofragmentable anastomosis ring is faster ant there are no significant differences regarding intraoperative complications rate, period of ileus, time to reintroduce the oral diet, mortality and long term folloow-up. the incidence of anastomotic leak was higher in the group i . the endoscopic analysis demonstrate no difference because there was the same results for both groups . there was a significant higher incidence of exposed suture in suture anastomosis when compared to biofragmentable anastomosis ring. conclusions: it can be concluded that the biofragmentabl

Abstract: colorectal cancer is a clinical entity of a persistent relevance in clinical practice and its early diagnosis is a determinant factor to obtain better therapeutic results. tumor markers are helpful means for a better approach to individuals with such neoplasm. in the present review, the authors analyze the phases in which surgical-clinical treatment markers must be used: diagnosis, determination of tumor stage, establishment of prognosis and detection of recurrence. current and future markers and the consensus on their use are discussed. causal factors for errors in diagnosis with markers and perspectives of use are also presented.

Abstract: this paper analyzes two central theoretical assumptions regarded in the practice of teaching and learning philosophy: communicative action in habermas and thinking as a way of resistance in adorno. philosophy and its teaching are developed from habermas's theory of communicative action which provides us with a theoretical basis for reflection and critical education. in the adornian perspective, the social function of education is intrinsically linked to the critique of the bourgeois society and, therefore, the cultural industry. adorno seeks to show that formal education has a strong power of resistance against the chaotic path of civilization. bringing this adornian sense of resistance to the practice of philosophy teaching is the purpose proposed here. teaching philosophy does not consist of accepting the political, institutional and social enforcements as natural. the task of critical theory - as teaching philosophy -, has a dimension that refers to the pursuit of autonomy by the individual and his social emancipation.

Abstract: context: identification of risk factors for requiring transfusions during surgery for colorectal cancer may lead to preventive actions or alternative measures, towards decreasing the use of blood components in these procedures, and also rationalization of resources use in hemotherapy services. this was a retrospective case-control study using data from 383 patients who were treated surgically for colorectal adenocarcinoma at "funda??o pio xii", in barretos-sp, brazil, between 1999 and 2003. objective: to recognize significant risk factors for requiring intraoperative blood transfusion in colorectal cancer surgical procedures. methods: univariate analyses were performed using fisher's exact test or the chi-squared test for dichotomous variables and student's t test for continuous variables, followed by multivariate analysis using multiple logistic regression. results: in the univariate analyses, height (p = 0.06), glycemia (p = 0.05), previous abdominal or pelvic surgery (p = 0.031), abdominoperineal surgery (p<0,001), extended surgery (p<0.001) and intervention with radical intent (p<0.001) were considered significant. in the multivariate analysis using logistic regression, intervention with radical intent (or = 10.249, p<0.001, 95% ci = 3.071-34.212) and abdominoperineal amputation (or = 3.096, p = 0.04, 95% ci = 1.445-6.623) were considered to be independently significant. conclusion: this investigation allows the conclusion that radical intervention and the abdominoperineal procedure in the surgical treatment of colorectal adenocarcinoma are risk factors for requiring intraoperative blood transfusion.

Abstract: objective: the objective of the present study was to clarify the relationship between cardiopulmonary bypass with the use of a heart-lung machine and gallstones in a short-term follow-up. method: a total of 135 patients with ischaemic heart disease were included in this study. all were followed up by the cardiology department of hospital s?o paulo, federal university of s?o paulo. they were divided into three groups: group 1 - 51 patients who were treated clinically; group 2 - 43 patients who underwent coronary artery grafting bypass without cardiopulmonary bypass; and group 3 - 41 patients who underwent coronary artery grafting bypass with cardiopulmonary bypass and the use of a heart-lung machine. there were no statistically significant differences between the groups in relation to gender, age, body mass index or associated diseases (p<0.05). all the patients underwent ultrasound examination 12 months after beginning their cardiological treatment (clinical treatment alone or surgical plus follow-up). results: the prevalence of gallstones in the groups was: group 1 - 7.84%, group 2 - 11.62%, and group 3 - 19.51%. there was no statistically significant differences between the groups (p = 0.248). conclusion: it was concluded that cardiopulmonary bypass does not appear to have a close relationship with gallstone formation one year after coronary artery bypass grafting. however, long-term follow-up is advisable.
