Abstract: background and objectives: mediastinitis is a serious complication of median sternotomy and is associated to significant morbidity and mortality. the aim of this study is to identify which option of harvesting internal thoracic artery (ita), pedicled or skeletonized, is associated with lower rates of mediastinitis after coronary artery bypass grafting surgery (cabg) in elderly, in the division of cardiovascular surgery of procape. methods: retrospective study of 160 elderly who underwent consecutive cabg between may 2007 and june 2011. eleven preoperative variables, four intraoperative variables and eight postoperative variables possibly involved in the development of postoperative mediastinitis were evaluated between two groups: cabg with skeletonized ita (n=80) and pedicled ita (n=80). univariate and multivariate logistic regression analyses were applied. results: the incidence of mediastinitis was 6.8% (n=11), with a lethality rate of 54.5% (n=6). the skeletonized ita group were more exposed than pedicled ita group to obesity (n=12 vs. n=4; 15% vs. 5%; p=0.035) and multiple transfusions (n=25 vs. n=11; 31.2% vs. 13.7%; p=0.008). the pedicled ita group presented a greater risk of mediastinitis after cabg than skeletonized ita group (n=10 vs. n=1; 12.5% vs. 1.2%; unadjusted or 11.3; 95% ci 1.4 - 241.5; p=0.008). in multivariate analysis, this difference maintained statistically significant (adjusted or 5.2; 95% ci 1.5-495.8; p=0.012), being considered an independent association. conclusions: we suggest that elderly should be considered for strategies to minimize risk of infection. in elderly that undergo unilateral ita, the problem seems to be related to how ita is harvested. elderly should always be considered for use of skeletonized ita.

Abstract: This study aimed to analyze how academic experiences developed by Master's degree students in Business Administration from a private institution situated in Belo Horizonte (MG), contributed to the formation and development of their professional competences, including the teaching ones. The theoretical framework focused on the theme of professional competence and on the analytical model adopted, namely by Paiva (2007). The research was characterized as descriptive, employing a qualitative approach along the lines of a case study. The unit of analysis corresponded to the research subjects, which are the graduates of such a course. Data collection was carried out by means of questionnaires with open and closed questions. The data of 24 questionnaires were processed according to their nature (univariate descriptive statistics for socio-demographic information and content analysis of the responses to qualitative questions). The analysis of the collected data were separated into three parts: formal description of the academic experiences which were gained in the master's program; profile of the respondents; and the graduate’s academic experiences and professional competences. The most recursive experience, out of 48 of which were reported, was the one found in a research (21 of them) which directly involved the interests of the Master’s degree students in gaining experience, improving and even "training" for the dissertation. The second most performed by the group of respondents, was the business experience followed by the teacher’s one, although they showed a lower level of competence, given the professional background of the graduates where their choice was concerned. As teachers and businessmen, they chose to do something they already knew, in which we could not notice any significant advances on the formation and development of their professional competences.

Abstract: it was analyzed the safety and mechanical resistance of 30 vertebral bodies obtained from human cadavers submitted to "vertebroplasty" were analyzed. after bone "densitometry", they were distributed into two groups: a and b. in group a, they were compressed to the second apex of force (graph by force of deformation), while in the group b, to the first. acrylic cement was injected in the vertebral body by transpedicular access. it was observed the cement leakage and the temperature of the vertebral body. the resistance was tested and compared to the one of vertebrae not compressed before. the surrounding structures can be damaged due to the extravasation of the cement. considering the temperature, this technique is safe, since extravasation does not take place. the resistance of the vertebra after the procedure is dependent on the degree of initial flattening, since bodies which had smaller flattening, presented the largest resistances.

Abstract: OBJETIVO: Revisar a literatura especializada a respeito dos adenocarcinomas duodenais primários e comparar os dados com os aspectos observados nesta casuística. MéTODOS: Seis doentes com esta neoplasia, excluídas as les es peri-ampulares, foram operados na área de Est mago e Duodeno do Departamento de Cirurgia da Santa Casa de S o Paulo, entre 1991 e 1999. Houve predominancia do tumor no sexo masculino e na 6feminine década de vida. Os sinais e sintomas mais freqüentes foram o emagrecimento (83,3%) e a obstru o intestinal cr nica (66,6%), com média de dura o de seis meses. A gastroduodenoscopia fez o diagnóstico, posteriormente confirmado pela histologia. Utilizamos a tomografia computadorizada e a ultra-sonografia para determinar o estádio da doen a. Em três pacientes com les o restrita à parede do órg o, praticou-se a ressec o duodenal segmentar curativa, e nos outros três, a deriva o duodenal paliativa, pois o tumor infiltrava órg os adjacentes. RESULTADOS: O tempo de interna o pós-operatória variou de 5 a 9 dias, com média de 7,3 dias. A mortalidade operatória foi 16,6% (um doente). N o indicamos tratamento complementar com quimio ou radioterapia. O acompanhamento ambulatorial vem ocorrendo em períodos que variam de 15 a 20 meses. Os três pacientes submetidos à ressec o cirúrgica curativa est o sem evidências de recidiva até o 15masculine, 16masculine e 18masculine mês de pós-operatório. Houve seguimento de um e três meses nos dois pacientes submetidos a cirurgias paliativas, depois do que se perderam. CONCLUS O: O pequeno número de casos relatados n o permitiu conclus es mais consistentes a respeito dos adenocarcinomas duodenais.

Abstract: the objective of this work was to verify the degree and type of heart damage of elderly chagasic patients seen at an outpatient referral center and to compare them with the changes found in young chagasic patients with a similar degree of heart damage. elderly and young patients without advanced cardiopathy presented good functional behavior. elderly patients with advanced cardiopathy had more ventricular premature beats (vpb) in 24 h and less functional capacity in the exercise test than young patients of the same subgroup. there was a higher occurrence of effort-induced vpb and a lower prevalence of severe forms in elderly men, suggesting that chagas' disease may have a worse evolution in males. the association of cardiac damage characteristic of aging with the secondary damage due to chagas' disease could explain the greater functional damage found in elderly chagasic patients. thus, it appears that the physiopathological components of chagas' disease do have an influence on the clinical course of cardiopathy in the elderly population.

Abstract: the patient with peritoneostomy is difficult to manege due to the losses of water and alectrolytes, the difficult volemic replacement, the great number of daily dressings and the risk of infection. the use of system vac allows the acurate measurement of the losses for a period of 48 hours, that can be renewed, facilitates the volemic replacement, decreases the infection and contamination risk and creates a humid environment that helps the healing process. when compared with traditional processes beyond the advantage verified with system vac, the costs are lower. a reduction of the risk and the period of hospital stay also occurs. the authors present a case carried out in the hc-ufpe that registers these advantages.

Abstract: in spite of it's decreasing incidence in the last years, gastric cancer remains the most frequent cause of death by malignant. prognosis depends on gastric wall tumor invasion, lymph node involvement and distant metastasis. small lymph nodes (less than 1 mm) are rarely identified, and, disease status and prognosis could change if some are metastatic. to identify lymph nodes in gastrectomy and lymphadenectomy specimens from gastric cancer, we have used a lymph node revealing solution (lnrs) after having taken the visible and palpable lympg nodes off. we have found 222 nodes with this technique (17.1 per patient) and more 123 nodes with lnrs (9.5 per patient), 55.5% additional nodes. biopsies have shown 39 metastatic nodes revealed by the traditional method and eight with lnrs. statistics showed that lnrs was effective in lymph nodes detection. lnrs revealed nodes were smaller. disease status did not change after addiction of lnrs detected nodes. we concluded lnrs was effective in lymph nodes searching from the studied specimens.
