Gaspar da Cruz and his book \"Tratado das Coisas da China\": mundialization and Luso-Chinese interactions in the 16th century

A presente dissertação tem como objetivo a análise do Tratado das Coisas da China (1570) de Frei Gaspar da Cruz, visando compreender a inserção desta literatura de viagem no processo de mundialização do século XVI, levado a cabo pelas naus da expansão ibérica, sobretudo portuguesa. A partir desta obra, pretende-se espelhar o processo de relações estabelecido entre portugueses e chineses, tomando a narrativa como registro histórico que constrói a imagem da China no século XVI.This study encompasses the analysis of the book Tratado das Coisas da China by Friar Gaspar da Cruz, as an attempt to understand the addition of travel literature in the 16th century\'s mundialization process, which was undertaken by the Iberian maritime exploration led by Portugal during the Age of Discovery. Taking Gaspar da Cruz\'s work as basis, the study aims to mirror the Portuguese-Chinese relations established at the time, understanding travel narrative as a historical record that substantiates such relations, providing for an intercultural process with interlaced views

Assessment of sternal closure using titanium plate

INTRODUCTION: The use of plates and screws for more rigid fixation of the sternum, without maintaining contact between the upper portion of the sternum and mediastinum. The present study seeks new choice of plate with a significant difference, the same does not need to be removed in order to proceed to open when necessary sternal emerging opening of the bone. OBJECTIVE: The current study aims to evaluate the efficacy and safety of this procedure. METHODS: To this end, we selected ten patients with coronary artery disease have shown no significant risk factors for mediastinitis. The surgery was thus performed in the usual way that all patients with coronary artery disease surgeries are done at the institution. Only at the time of sternal closure is that there was a change, with the combination of steel wires and plates. RESULTS: All cases had sternal closure properly with good outcome in the medium term. CONCLUSION: The use of plates ENGIMPLAN proved safe and effective for sternal closure

Impacto dos parâmetros espinopélvicos pré-operatórios na correção de lordose segmentar após fusão intersomática lombar por via lateral de um nível

Resumo Objetivos O presente estudo teve como objetivo avaliar se os parâmetros espinopélvicos pré-operatórios podem influenciar o ganho da lordose segmental após fusão intersomática lombar por via lateral de um nível. Métodos Os seguintes parâmetros radiológicos foram medidos nos raios X: incidência pélvica, lordose lombar, versão pélvica, lordose L4S1, lordose segmental do nível operado, índice intraoperatório de lordose segmentar, mismatch pélvico (IP-LL), proporção de lordose distal, delta de lordose segmentar, PT &gt; 20, inclinação sacral real e inclinação sacral ideal, e a correlação dessas variáveis com o ganho da lordose segmentar foi investigada. Posteriormente, foi realizada uma análise exploratória de cluster para identificar características comuns entre os pacientes e o ganho de lordose segmentar. Resultados O presente estudo contou com 144 pacientes, dos quais 76% apresentaram ganho de lordose segmentar. Os parâmetros mais correlacionados com o ganho de lordose segmentar foram lordose segmentar pré-operatória (−0,50) e delta intraoperatório de lordose (0,51). Além disso, os pacientes dos grupos de incidência pélvica (IP) alto tiveram tendência de ganho de lordose segmental maior (p &lt; 0,05) e redução do risco de perda de lordose segmental (chances 6.08). Conclusão Pacientes com perfis de IP médios baixos apresentaram maiores chances de perda de lordose segmentar. No entanto, os parâmetros espinopélvicos pré-operatórios por si só não parecem desempenhar um papel significativo no destino do ganho da lordose segmentar.</jats:p

A new classification of post sternotomy dehiscence

The dehiscence after median transesternal sternotomy used as surgical access for cardiac surgery is one of its complications and it increases the patient's morbidity and mortality. A variety of surgical techniques were recently described resulting to the need of a classification bringing a measure of objectivity to the management of these complex and dangerous wounds. The different related classifications are based in the primary causal infection, but recently the anatomical description of the wound including the deepness and the vertical extension showed to be more useful. We propose a new classification based only on the anatomical changes following sternotomy dehiscence and chronic wound formation separating it in four types according to the deepness and in two sub-groups according to the vertical extension based on the inferior insertion of the pectoralis major muscle

Use of the pectoralis major fasciocutaneous flap in the treatment of post sternotomy dehiscence: a new approach

OBJECTIVE: To describe a new surgical technique for the treatment dehiscence after median thoracotomy transsternal using fasciocutaneous flap composed of the pectoralis major fascia. METHODS: Between January 2009 and December 2010, from 1,573 patients submitted to coronary artery bypass graft, 21 developed wound dehiscence after sternotomy and were treated with bilateral pectoralis major muscle fasciocutaneous flap, including partial portion of the rectus abdominis fascia. Patients were followed for a minimum of 90 days postoperatively. RESULTS: All patients had favorable outcome following 90 days, not having any partial or total dehiscence. There were no cases of postoperative infection. CONCLUSION: The procedure was rapid and effective. Compared with techniques using muscle, myocutaneous or greater omentum flaps, this surgery was less aggressive and maintained the integrity of tissue region. The authors considered that this technique should be used as the first option, leaving the flaps to more complex cases of relapse.</jats:p
