Objetivo:1) Descrever as infecções relacionadas à derivação ventricular externa; 2)Descrever o perfil clínico e microbiológico das infecções em neurocirurgia em um hospital de ensino terciário no centro de SP. Métodos: Foi realizado um estudo retrospectivo dos casos de infecções em neurocirurgias, durante o período de Janeiro de 2017 a Setembro de 2018, dos pacientes da Irmandade Santa Casa de Misericórdia de São Paulo. Os resultados obtidos foram baseados em análise de prontuário, banco de dados do Serviço de Controle de Infecção Hospitalar e do laboratório. Resultados: No período de janeiro de 2017 a setembro de 2018, incluímos 81 pacientes, sendo 66 adultos e 15 pediátricos. Nas duas faixas etárias houve predomínio do gênero masculino. A idade média dos adultos foi de 48,2 anos e das crianças foi de 4,8 meses. Segundo a classificação da cirurgia de acordo com o CDC, 72% das cirurgias eram limpas (44 adultos e 14 crianças), 27% (22) eram potencialmente contaminadas (todos em adultos) e a única infectada (1%) era pediátrica. Das 81 ISC, 26 foram relacionadas à DVE. A distribuição dos casos por faixa etária ficou 85% para adultos (95% urgência) e 15% em criança (75% urgência). taxa de ISC de todas as neurocirurgias realizadas no período foi de 6,60, enquanto a taxa de ISC das cirurgias limpas foi de 4,73. A densidade de incidência destas infecções foi de 11,09 por 1000 dve-dia. As ISC foram separadas quanto às suas topografias: 26 (32%) foram ISC tipo órgão/espaço com DVE, 47 (58%) foram ISC tipo órgão/espaço sem DVE e 8 (10%) foram ISC tipo incisional profunda. Obtivemos documentação microbiológica em 41 (51%) dos casos, sendo o líquido cefalorraquidiano (76%) a principal amostra enviada para análise. Em seis (15%) pacientes houve isolamento polimicrobiano. Foram isolados 47 agentes: 53% cocos Gram positivos, 32% Enterobactérias, 13% bacilos Gram negativos não fermentadores e 2% levedura. Conclusão: Após análise dos resultados deste estudo As infecções relacionadas a derivação ventricular externa se caracterizam por predominarem nas cirurgias limpas e de urgência no hospital e período estudado. O tempo de internação hospitalar foi elevado bem como o tempo de permanência da DVE (superior a 56 dias). Tanto a taxa de ISC quanto a densidade de incidência dessas infecções por DVE-dia foram elevadas. A mortalidade das ISC em 30 dias foi de 16%. Porém, separando os casos de pacientes com DVE, obtivemos uma mortalidade atribuída à IAV de 30%.O agente infeccioso mais encontrado foi o Coco Gram-positivo, em especial, o Staphylococcus spp. que se mostrou resistente à meticilina.

INTRODUÇÃO: As intervenções coronárias percutâneas (ICPs) em centros sem cirurgia cardíaca representam uma real opção no contexto atual da cardiologia intervencionista. O propósito deste estudo foi avaliar as mudanças na incidência e indicações para cirurgia de revascularização miocárdica de emergência em pacientes submetidos a ICP de 1992 a 2005 MÉTODO: No total, 9.938 pacientes submetidos a ICP em dois centros foram divididos em três grupos: período pré-stent, de 1992 a 1996 (n = 2.500), período intermediário, de 2002 a 2003 (n = 3.711), e período mais recente, de 2004 a 2005 (n = 3.727) RESULTADOS: Com o advento dos stents passou-se a abordar uma população mais idosa (58,2 ± 10,7 anos vs. 62,7 ± 11,7 anos vs. 67,8 ± 11,6 anos; P = 0,01), com lesões mais complexas, do tipo B2/C (52,2% vs. 72,7% vs. 79%; P < 0,01), mas com melhora nos resultados de oclusão aguda (7,8% vs. 1,7% vs. 1,1%; P < 0,01) e de cirurgia de revascularização miocárdica de emergência (1,2% vs. 1,1% vs. 0,7%; P < 0,01) e consequente menor mortalidade (3,3% vs. 2,2% vs. 2%; P < 0,01). Foram identificados como preditores da necessidade de cirurgia de emergência o padrão de acometimento coronário multiarterial [odds ratio (OR) 3,42, intervalo de confiança de 95% (IC 95%) 1,75-6,7], infarto agudo do miocárdio (OR 3,65, IC 95% 2,3-5,8) e complexidade das lesões [tipo B2/C, American Heart Association/American College of Cardiology - AHA/ACC (OR 3,27, IC 95% 1,66,75)]. A característica que exerceu efeito protetor foi a utilização de stent (OR 0,58, IC 95% 0,4-0,85) CONCLUSÃO: Os avanços da técnica, do material e da farmacoterapia adjunta têm contribuído com a ICP no sentido de diminuir a necessidade de cirurgia de revascularização miocárdica de emergência. BACKGROUND: Percutaneous coronary interventions (PCI) in centers without cardiac surgery represent a real option in the current context of interventional cardiology. The purpose of this study was to evaluate changes in the incidence and indications for coronary artery bypass grafting in patients undergoing PCI from 1992 to 2005 METHOD: Data from 9,938 patients undergoing PCI in two centers were divided into three groups: pre-stent period, from 1992 to 1996 (n = 2,500), intermediate period, from 2002 to 2003 (n = 3,711) and more recent period, from 2004 to 2005 (n = 3,727) RESULTS: Since the advent of stents, an older population (58.2 ± 10.7 years vs. 62.7 ± 11.7 years vs. 67.8 + 11.6 years; P = 0.01), with more complex type B2/C lesions (52.2% vs. 72.7% vs 79%; P < 0.01) is being treated, with a lower rate of acute vessel occlusion (7.8% vs. 1.7% vs. 1.1%; P < 0.01), emergency coronary artery bypass grafting (1.2% vs. 1,1% vs. 0.7%; P < 0.01) and mortality (3.3% vs. 2.2% vs. 2%; P < 0.01). Predictors of the need of emergency bypass surgery were multivessel disease [odds ratio (OR) 3.42, 95% confidence interval (95% CI) 1.75-6.7), acute myocardial infarction (OR 3.65, 95% CI 2.3-5.8) and lesion complexity [type B2/C, American Heart Association/American College of Cardiology - AHA/ACC (OR 3.27, 95% CI 1.6-6.75)]. The use of stents, however, conferred a protective effect against the need of emergency bypass surgery (OR 0.58, 95% CI 0.4-0.85) CONCLUSION: Advances in technology, devices and adjunctive pharmacotherapy have improved PCI, reducing the need of emergency coronary artery bypass grafting.

OBJETIVO: Avaliar o valor do ecocardiograma Doppler(ECO) transtorácico na identificação de perviabilidade da anastomose entre artéria torácica interna esquerda (ATIE) e interventricular anterior, realizada pela técnica de revascularização miocárdica pela minitoracotomia sem circulação extracorpórea. MÉTODOS: Estudaram-se os primeiros 12 pacientes, consecutivos, no período de pós-operatório intra-hospitalar pelo ECO, utilizando-se transdutores de 5MHz, pela via paraesternal esquerda, preferencialmente. Foram analisadas velocidades máximas e integrais de velocidade dos componentes sistólico e diastólico das curvas espectrais de fluxo Doppler. Todos pacientes foram submetidos à cinecoronariografia, enquanto hospitalizados. RESULTADOS: O ECO foi exeqüível em 93% dos pacientes. Nos com anastomose pérvia (6/7), observou-se ao estudo Doppler amplo componente diastólico (padrão A). Naqueles com anastomose obstruída (4/4) o padrão observado foi de predomínio sistólico (padrão B) (p=0,003*). CONCLUSÃO: O ECO da ATIE anastomosada com a artéria interventricular anterior, após cirurgia de revascularização miocárdica pela técnica de minitoracotomia, permitiu caracterizar precocemente, com precisão, a perviabilidade da anastomose. PURPOSE: To study the value of Doppler echocardiography as a tool for the evaluation of left internal thoracic artery graft (LITAG) patency in patients who underwent coronary revascularization using minimally invasive bypass surgery without extracorporeal circulation. METHODS: The first 12 consecutive patients were studied after coronary artery bypass surgery using a 5MHz Doppler transducer. Doppler signals for the systolic and diastolic flow velocities were preferably obtained in the second intercostal space. All patients underwent coronary angiography while hospitalized. RESULTS: The exam was feasible in 93% of patients. Doppler flow pattern was predominantly diastolic (pattern A) in patients with patent anastomoses (6/7). In patients with occluded anastomoses (4/4) Doppler flow pattern was predominantly systolic (pattern B) (p=0.003). CONCLUSION: Internal thoracic artery flow pattern as measured by Doppler echocardiography after minimally invasive coronary artery bypass graft surgery is an accurate method for identifying LITAG patency.

OBJETIVO: Tendência atual em todas as áreas da cirurgia aponta para táticas e técnicas cirúrgicas que tornem o ato operatório cada vez menos invasivo. O objetivo do presente estudo foi avaliar a viabilidade da revascularização do miocárdio através de mínima incisão torácica (minitoracotomia esquerda), sem circulação extracorpórea. CASUÍSTICA E MÉTODOS: De setembro de 1995 a março de 1996, um total de 19 pacientes portadores de lesões isoladas do ramo interventricular anterior (RIA) e/ou diagonal (Dg) foram submetidos a revascularização do miocárdio, tendo, como via de acesso, toracotomia anterior paraesternal esquerda, de aproximadamente 7 cm de extensão, ao nível do 4º espaço intercostal. Através dessa incisão foi dissecada a artéria torácica interna esquerda (ATIE) em extensão suficiente para a realização da anastomose com o RIA efetuada sem circulação extracorpórea. No 2º dia de pós-operatório esses pacientes foram submetidos a arteriografia e eco-Doppler transtorácico da ATIE para verificação das condições do enxerto e da persistência de fluxo pelos ramos intercostais não ligados por ocasião da dissecção parcial da artéria. RESULTADOS: Todos os pacientes tiveram boa evolução pós-operatória. O resultado da ATIE realizado em 16 dos 19 pacientes operados mostrou padrões angiográficos excelentes em 13 deles. Não se demonstrou contrastação dos ramos intercostais não ligados durante a dissecção. O Doppler transtorácico se correlacionou com as condições dos enxertos. CONCLUSÃO: Os resultados iniciais obtidos na revascularização do miocárdio através de minitoracotomia esquerda sugerem ser esta uma boa alternativa tática para portadores de lesão isolada do RIA com excelente resultado estético. There is a tendency in all fields of surgery to move towards less invasive surgical techniques in recent years. The end point of this study was to analyse the possibility of myocardial revascularization through a minimum left thoracotomy approach. From September 1995 till March 1996 we operated on 19 patients that had isolated lesion of interventricular anterior artery (IAA) and/or diagonal. The anastomoses were made by a left minor thoracotomy, opening the pleura at the 4º intercostal space. Through this incision we dissected the thoracic internal artery with ligation of only few branches. The anastomoses were performed without extracorporeal circulation, with a simple interruption of coronary blood flow. At the second postoperative day we studied the patients with angiography and transthoracic echo-Doppler, to verify patency and flow. All patients had uneventful recovery without major complications. Angiography was made in 16 out of 19 and showed patency in 13. The 3 patients with graft occlusion were reoperated on without complications. The presented technique did not involve ligation of the intercostal branches, however these branches were not demonstrated by angiography. Transthoracic Doppler showed good relationship with angiographic findings. The initial results with this technique suggest that we can have another option of minimum invasive myocardial revascularization for selected patients.

Nursing professionals at health care institutions should be prepared to suspect and identify cases of pulmonary tuberculosis at the earliest possible stage, in view of the risk of their contagion and consequent sickness. The prevention aspects should be valued in the performance of their activities, to the effect of remaining continuously attentive, to adopt safety measures that prevent the intra-hospital transmission of the disease. This study was aimed at identifying the knowledge of nursing team members of protective measures to be deployed in caring for adult patients suspected of having or diagnosed with pulmonary tuberculosis, confined in clinical-surgical and emergency units of a university hospital. This exploratory, transversal onsite study included 280 nursing professionals, comprising nurses (31-11.43%) and nursing assistants (249-88.57%). The material was gathered by applying a questionnaire with closed and open-ended questions. The material gathered was organized and the content analysis was used for the handling of data. The nursing professionals expressed their understanding of the disease and their knowledge of protective measures in the care of patients suspected of having or diagnosed with pulmonary tuberculosis. The study provided means of identifying the needs of nursing professionals focused on biosafety aspects in relation to the performance of their practice, permitting the formulation of subsidies for the continued education service and Hospital Infection Control Service of the Institution (SCIH).

Resumen La trilogía de Matrix ofrece una poderosa metáfora sobre la convergencia hombre-máquina. Los resquicios de esa interface llevan implícita una dualidad que permite presentar el viejo tópico de la confusión entre fantasía y realidad en términos de “espejismos virtuales”, como es propio de la era de la Inteligencia Artificial. Pero la navegación en estructuras paralelas a la realidad, así como la íntima conexión entre el hombre y los computadores, tienen referencias reales. Los buscadores de Internet rastrean la información sobre una trama de hipertexto, al modo de los Centinelas de Matrix. Las aplicaciones informáticas de networking permiten reproducir y ampliar las redes personales a través de la comunicación mediada por ordenador. En este artículo evaluamos (a) algunos de los buscadores de Internet y (b) de las herramientas de contactos más difundidos en la actualidad. Para ello utilizamos como referencia teórica y metodológica el análisis de redes sociales (ARS). Tanto los buscadores como los sitios Web de contactos hacen un uso predominantemente metafórico de la idea de red, con algunas aplicaciones de la representación visual. Sin embargo, algunos desarrollos como Touchgraph (entre los buscadores) y Visible Path (para el networking de ventas) ilustran los beneficios que pueden derivarse de la aplicación sistemática del ARS en este ámbito. Como conclusión, sugerimos algunas líneas de investigación del análisis de redes que pueden resultar beneficiosas en este campo: (a) la sistematización de los procedimientos de representación visual de las redes, con fines descriptivos; (b) la identificación de comunidades; (c) la construcción de redes globales a partir de redes personales; (d) el estudio de las estrategias con las que los actores individuales hacen uso de las redes complejas, y (e) la monitorización del crecimiento de la red. Con este bagaje, las técnicas del ARS pueden contribuir a mejorar la adecuación del diseño tecnológico a los usos sociales. Abstract The Matrix trilogy offers a powerful metaphor about the man-machine convergence. This duality is efficiently represented by the the internet search engines (as Matrix centinels) and the social software applications. Both of them use widely the network representation of data. Departing from the Social Network Analysis as a theoretical and methodological framework this paper explores the ways in which the (a) standardization of visual methods of representation, (b) community mapping, (c) global personal networks, (d) strategies for network navigation and (e) network change monitorization could be improved.

- Abstract
Purpose: To analyze the results of myocardial revascularization through small left anterior thoracotomy utilizing the left thoracic internal artery (LTIA) to left anterior descending coronary artery (LAD) without cardiopulmonary bypass, in order to simplify the operative procedure., Methods: From September/95 till August/96 we operated on 45 patients with lesions in LAD or LAD and diagonal arteries that were revascularized with an anastomoses of the LTIA to LAD or LAD and diagonal as composite grafts, through left anterior small thoracotomy. In the second postoperative day 43 out of 45 patients were restudied with arteriography and/or transthoracic echocardiography that showed excellent patency in 39 of them., Results: Six patients with obstruction or stenoses were reoperated through median sternotomy without complications. We did not observe flow through intercostal arteries in these restudies except in cases of obstructed anastomosis, showing that it is not necessary to ligate these branches. We observed too, excellent correlation between angiographic patterns and diastolic flows detected in the thoracic internal artery with transthoracic echocardiography., Conclusion: These initial results suggest that this approach may be good to a subset of patients with lesions in LAD and/or diagonal arteries and if associated with complementary angioplasties of other coronary arteries may be the best choice of invasive treatment of coronary insufficiency in a near future.

- Abstract
Purpose: Analysis of the first 20 patients with acute myocardial infarction (AMI) who were treated with intravenous APSAC., Methods: Twenty patients with AMI less than 6 hours of duration of symptoms were treated with IV APSAC bolus of 30 mg. Seventeen were males, ages ranging between 40 and 73 (mean 54) years. The first angiographic study was performed in 90 minutes and 5-7 days after drug administration., Results: In the angiographic study performed at 90 minutes the infarct--related artery were left anterior descending (LAD) in 7 patients (35%), right coronary artery (RCA) in 9 (45%) and left circumflex (LCX) in 4 (20%). In 14 (70%) of the patients had patent infarct-related artery and the mean of left ventricular ejection fraction (LVEF) was 0.49 +/- 0.15. In six non recanalized patients the mean LVEF was 0.40 +/- 0.14. No complications were observed, and in the second angiographic study one patient showed reocclusion of the infarct-related artery., Conclusion: Because of easy application (IV bolus), no complication and high rate of early recanalization, IV APSAC seems to be an efficient thrombolytic agent in the treatment of patients with AMI.

- Abstract
A 49 year-old woman with acute pulmonary thromboembolism and severe hemodynamic impairment was successfully treated with tissue-type plasminogen activator (r-TPA). She did not have previous pulmonary or cardiac diseases. Thirty days after immobilization of the right ankle, she had a sudden onset of dyspnea, epigastrial pain and syncope. As heparin therapy was unsuccessful, 90 mg of IV r-TPA was administered. There was rapid clinical and hemodynamic improvement of her condition. Pulmonary scanning one week later was normal and she was discharged without symptoms 12 days after the acute episode.
