Revista do Colégio Brasileiro de Cirurgi?es , 2013,
Abstract: OBJETIVO: Avaliar a incidência de fístula faringocutanea após laringectomia total e tentar identificar os fatores preditores. MéTODOS: No período de maio de 2005 a abril de 2010, 93 pacientes foram submetidos à laringectomia total. Foram avaliadas as complica es per e pós-operatórias e comparadas com as seguintes variáveis: sexo, estado nutricional, traqueostomia prévia, localiza o do tumor primário, tipo de opera o realizada, estadiamento de acordo com o TNM, tratamento prévio com quimioterapia e/ou radioterapia, utiliza o de retalhos para reconstru o e margem cirúrgica. Todos os pacientes apresentavam a neoplasia em estádio avan ado segundo o TNM. RESULTADOS: 14 (15,1%) pacientes evoluíram com fístula salivar no pós-operatório. O tempo médio de aparecimento da fístula salivar foi 3,5 dias, com desvio padr o de 13,7 dias. Comparando a fístula salivar com as variáveis TNM, tipo de opera o e esvaziamento cervical, traqueostomia prévia, utiliza o de retalho miocutaneo, rádio e quimioterapia pré-operatória e margem cirúrgica, n o foi observado diferen a estatisticamente significativa (p>0,05). CONCLUS O: A incidência de fístula salivar foi 15,1% e n o foi encontrado fator preditor para sua forma o. OBJECTIVE: To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. METHODS: From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy, tumor location, type of surgery, TNM staging, prior treatment with chemotherapy and/or radiotherapy, use of flaps for reconstruction and surgical margin. All patients presented with advanced neoplastic disease according to TNM. RESULTS: 14 (15.1%) patients developed postoperative salivary fistula. The mean time to onset of salivary fistula was 3.5 days, with a standard deviation of 13.7 days. Comparing salivary fistula with TNM variables, type of operation and neck dissection, prior tracheotomy, use of flap, preoperative radio and chemotherapy and surgical margin, there was no statistically significant difference (p> 0,05). CONCLUSION: The incidence of salivary fistula was 15.1% and no predictive factor for its formation was found.
Laringectomia de resgate: utiliza o do retalho miocutaneo de peitoral maior na preven o de fístula faringocutanea The usefulness of a pectoralis major myocutaneous flap in preventing salivary fistulae after salvage total laryngectomy

Abstract: Laringectomias de resgate est o associadas a altas taxas de complica es pós-operatórias. O uso de retalhos na reconstru o do transito faríngeo poderia reduzir a incidência destas complica es. OBJETIVO: Avaliar a utilidade do retalho miocutaneo de músculo peitoral maior na preven o da fístula salivar no pós-operatório de laringectomia total de resgate. MéTODO: Estudo retrospectivo, realizado de abril/2006 a maio/2011, com 31 pacientes portadores de CCE de laringe recidivado, tratados previamente com quimiorradioterapia ou radioterapia isolada, submetidos à laringectomia de resgate. Destes 31 pacientes, a reconstru o da faringe foi realizada com utiliza o do retalho miocutaneo de músculo peitoral maior em 19 (61%) casos, enquanto o fechamento primário ocorreu em 12 pacientes (39%). RESULTADOS: Foi observada taxa de fistula salivar em (16%) dos pacientes em que se utilizou o retalho e 58% nos pacientes submetidos a fechamento primário da faringe (p < 0,02). N o foi observada diferen a estatisticamente significativa entre os grupos em rela o ao tempo médio de aparecimento de fistula e reintrodu o da dieta por via oral, bem como tempo de uso de cateter nasoentérico para alimenta o. CONCLUS O: O retalho miocutaneo do músculo peitoral maior mostrou-se como op o capaz de reduzir incidência de fistula salivar em laringectomias de resgate. Salvage laryngectomy in patients treated with organ preservation protocols is associated with high rates of postoperative complications. The use of non-irradiated tissue flaps in pharyngeal reconstruction could reduce the incidence of these complications. OBJECTIVE: This study aims to evaluate the usefulness of the pectoralis major myocutaneous flap in preventing salivary fistulae during the postoperative period of salvage total laryngectomy (TL). MATERIALS AND METHOD: This retrospective study enrolled 31 patients operated between April of 2006 and May of 2011. All patients had advanced cancer at the time of the salvage procedure and had been treated with chemoradiotherapy or radiotherapy alone. Pharyngeal reconstruction was performed using pectoralis major myocutaneous flap in 19 cases (61%); primary wound closure occurred in 12 patients (39%). RESULTS: Salivary fistulae occurred in 16% of the patients who received the flap and in 58% of the patients with primary closure of the pharynx (p < 0.02). No statistically significant differences were noted between the groups with respect to the mean time for fistula formation, reintroduction of an oral diet, or use of a nasoenteric tube for feeding. CONCLUSION: The pectorali

Revista do Colégio Brasileiro de Cirurgi?es , 2012,
Abstract: OBJETIVO: Avaliar a incidência e os fatores preditores da hipocalcemia e hipoparatireodismo definitivo pós-tireoidectomia. MéTODOS: Foi dosado cálcio i nico no pré e no pós-operatório (primeiro, segundo e 30odia) em 333 pacientes submetidos à tireoidectomia. Naqueles que apresentaram hipocalcemia, as dosagens foram feitas também aos 90 e 180 dias de pós-operatório, quando se dosou também o paratorm nio. Os pacientes foram agrupados segundo a presen a ou ausência de hipocalcemia e avaliados segundo idade, sexo, fun o tireoidiana, volume tireoidiano, número de paratireoides identificadas e necessidade de reimplante de paratireoides, tipo de opera o, tempo operatório e diagnóstico histopatológico. RESULTADOS: A incidência de hipocalcemia temporária foi de 40,8% (136 pacientes), e hipoparatireoidismo definitivo de 4,2% (14 pacientes). Tireoidectomia total ou reopera o, esvaziamento cervical, hipertireoidismo, tempo operatório e idade acima de 50 anos foram fatores determinantes de incidência significativamente maior de hipocalcemia e hipoparatireodismo definitivo (p<0,05). CONCLUS O: os fatores preditores da hipocalcemia pós-operatória incluem idade (>50 anos), tireoidectomia total, reopera o, esvaziamento cervical e tempo operatório. Os fatores preditores do hipoparatireoidismo definitivo pós-tireoidectomia incluíram tipo de opera o, diagnóstico histológico e hipertireoidismo. OBJECTIVE: To evaluate the incidence and predictors of post-thyroidectomy definitive hypocalcemia and hypoparathyroidism. METHODS: We assessed ionic calcium preoperatively and postoperatively (first, second and 30th day) in 333 patients undergoing thyroidectomy. In those presenting hypocalcemia, measurements were also made 90 and 180 days after surgery, when parathormone was also dosed. Patients were grouped according to the presence or absence of hypocalcemia and evaluated according to age, gender, thyroid function, thyroid volume, number of parathyroid glands identified and need to parathyroid reimplantation, type of operation, operative time, and histopathological diagnosis. RESULTS: The incidence of temporary hypocalcemia was 40.8% (136 patients), and of definitive hypoparathyroidism 4.2% (14 patients). Reoperation or total thyroidectomy, neck dissection, hyperthyroidism, operative time and age above 50 years were factors related to higher incidence of hypocalcemia and definitive hypoparathyroidism (p <0.05). CONCLUSION: predictors of postoperative hypocalcemia included age (> 50 years), total thyroidectomy, reoperation, neck dissection and operative time. The predictors of

Abstract: purpose: to identify the commonest changes in chewing and swallowing as a result from curative tongue cancer surgery, with less than 50% of tongue resection and preservation of both mouth floor and tongue base. methosd: nine patients - six men and three women - were assessed during the pre-surgical period, using a specific protocol. during the mediate postsurgical period, five patients - four men and one woman - were reassessed using the same protocol. the kruskall wallis non-parametric test (test h) was used to analyze the significance of the results. results: the comparison between pre and postoperative results showed significant (p<0,05) changes from oral to enteral feeding. there was also a significant change in chewing efficiency, which became ineffective in all patients. it was significantly observed the patients' difficulty in handling the food bolus during the chewing process, causing difficulty in forming a cohesive bolus. this demonstrates that surgery influences this function, that is, the partial loss of the tongue undermines the chewing process. the swallowing process was also impaired by the surgery: the protocol demonstrated significant presence of oral stasis after swallowing, and compensatory head movements for swallowing solids. conclusion: the patients submitted to partial glossectomy presented significant alterations in chewing and swallowing as a result from surgical cancer treatment.

Abstract: Amebiasis can be considered the most aggressive disease of the human intestine, responsible in its invasive form for clinical syndromes, ranging from the classic dysentery of acute colitis to extra-intestinal disease, with emphasis on hepatic amebiasis, unsuitably named amebic liver abscess. Found worldwide, with a high incidence in India, tropical regions of Africa, Mexico and other areas of Central America, it has been frequently reported in Amazonia. The trophozoite reaches the liver through the portal system, provoking enzymatic focal necrosis of hepatocytes and multiple micro-abscesses that coalesce to develop a single lesion whose central cavity contains a homogeneous thick liquid, with typically reddish brown and yellow color similar to "anchovy paste". Right upper quadrant pain, fever and hepatomegaly are the predominant symptoms of hepatic amebiasis. Jaundice is reported in cases with multiple lesions or a very large abscess, and it affects the prognosis adversely. Besides chest radiography, ultrasonography and computerized tomography have brought remarkable contributions to the diagnosis of hepatic abscesses. The conclusive diagnosis is made however by the finding of Entamoeba histolytica trophozoites in the pus and by the detection of serum antibodies to the amoeba. During the evolution of hepatic amebiasis, in spite of the availability of highly effective drugs, some important complications may occur with regularity and are a result of local perforation with extension into the pleural and pericardium cavities, causing pulmonary abscesses and purulent pericarditis, respectively The ruptures into the abdominal cavity may lead to subphrenic abscesses and peritonitis. The treatment of hepatic amebiasis is made by medical therapy, with metronidazole as the initial drug, followed by a luminal amebicide. In patients with large abscesses, showing signs of imminent rupture, and especially those who do not respond to medical treatment, a percutaneous drainage must be performed with either ultrasound or computerized tomography guidance. Surgical drainage by laparotomy is reserved to patients with secondary infections.

Gest?o & Produ??o , 2011, DOI: 10.1590/S0104-530X2011000200002
Abstract: new forms of relationship and transaction between companies participating in the same supply chain have been applied to improve competitive conditions in the chain. the auto industry is a striking example of an industry in which the relationships between companies have been deeply renewed and motivated mainly by the influence of automakers in the primary suppliers, which in turn work with their own suppliers forming a competitive alliance. this article aims to study the relationship between customer-supplier in the brazilian automobile industrial park, to create a relational typology from case studies. technical visits were made in fourteen supplying companies to gather information about the main structural features and the relationship between manufacturers and suppliers in the brazilian automotive industry. interviews were conducted with managerial level professionals of industrial areas - production, logistics and supplies, product and process development, purchasing, and human resources. the results showed that the relationships depend on institutional characteristics of the supplier, the complexity of the technology components, the productive capacity, and the history of relationships between customers and suppliers. it could be concluded that the relationship between customers and the supplier companies surveyed are close to the characteristics of an associative model with contractual relationships and long-term high interdependence although price is still used as the main criterion for being successfully selected by automakers.
Strategies of Production in the Automobile Industry: a Multi-Case Study in Spain and Brazil
Rosangela Maria Vanalle,José Antonio Arantes Salles,Milton Vieira Junior
Brazilian Journal of Operations & Production Management , 2010,
Abstract: The aim of this paper is to identify and to analyze the manufacturing strategies of two supply chains of the automobile industry and the assemblers’ influences on the other participants in each chain. Two plants of the same assembler, one in Brazil and the other in Spain and their suppliers, were analyzed, using questionnaires and interviews. It was observed that the competitive priorities of the suppliers are strongly conditioned to the strategy of the assembler, and the ordination of these priorities in the Brazilian case is different from that in the Spanish case. One of the reasons of this difference in the ordination of priorities of the Brazilian and the Spanish companies can be explained by the traditional competitive capabilities for exporting of the Spanish automotive industry, which inserts in the world market a larger percentile of production than the Brazilian industry. Even so it can be confirmed that in Brazil and Spain the inter-business relationships are suffering a transition of mass production, with conflicting relationships supplier-manufacturer, for a relationship of larger cognitive density, characteristic of the presuppositions of organization of supplies based on the model flexible production or lean manufacturing.
