    Introdução: A terapia de pressão negativa tópica, auxiliada pela instilação de fluidos no leito das feridas, é comumente utilizada para tratar feridas complexas, especialmente, aquelas que contêm exsudato espesso e colonização bacteriana importante. No mercado, existem equipamentos industriais que aplicam essa terapia, porém, de alto custo, impossibilitando o seu uso na rede pública de saúde. Desse modo, o desenvolvimento de tecnologias, que promovam essa terapia com baixo custo, torna-se necessário. Objetivo: Desenvolver um dispositivo de terapia por pressão negativa com sistema de irrigação para fluidos e visualização da ferida de baixo custo. Métodos: Revisão das patentes existentes por meio da busca de anterioridade e comparação com o dispositivo do estudo. Na confecção dos protótipos, foi empregada como metodologia o Design Thinking para Patentes, aplicada à experimentação, por meio de protótipos de baixo custo para validar os conceitos. Esses protótipos necessitaram de equipamentos e técnicas, entre eles, ferramentas de design gráfico, impressão em três dimensões e soldagem de polímeros termoplásticos para desenvolver o curativo e registro da patente. Resultados: A patente desenvolvida configura um modelo de utilidade que se refere a um curativo de terapia por pressão negativa, compreendendo duas unidades estruturais, que se unem com o auxílio de dois anéis de pressão. Possui duas tubulações, inserindo uma oposta à outra, simetricamente e detém uma placa de resina sintética para fixação adequada no leito da ferida. Conclusão: Foi desenvolvido um dispositivo de baixo custo para o tratamento de feridas que utiliza a pressão negativa e a irrigação de fluidos.

    Engenharia tecidual utilizando microalgas na produção de curativos cutâneos: uma revisão bibliográfica
    (Universidade Federal de São Paulo, 2024-09-02) Rocha, Eslaine Shirlei da [UNIFESP]; Braga, Anna Rafaela Cavalcante [UNIFESP]; http://lattes.cnpq.br/1145965338858435
    O processo de cicatrização de feridas consiste na regeneração do tecido do organismo vivo, sendo uma etapa importante para a recuperação de pacientes. Graças às complexas etapas necessárias para que ocorra a cicatrização, a reconstituição epitelial da região perdura por um longo período. A presença de agentes patológicos como bactérias podem prolongar ainda mais o processo de cicatrização ao contaminar a região provocando uma infecção. Estudos clínicos mostram que a oxigenação adequada da região ferida acelera o processo de cicatrização, pois o oxigênio além de beneficiar a formação das fibras de colágeno, elimina as bactérias presentes na região. Assim, a utilização de curativos convencionais que impedem o contato direto da região lesada com o oxigênio presente no ar representa um empecilho para a aceleração do processo de cura. Nos últimos anos tem sido crescente o estudo e pesquisa para o desenvolvimento de curativos avançados biocompatíveis, isto é, que possuem afinidade com o sistema biológico. Paralelamente, estudos têm demonstrado que as microalgas, micro-organismos que realizam fotossíntese oxigenada possuem bioativos potencialmente terapêuticos. Assim, para a engenharia tecidual, a combinação de curativos biocompatíveis com as propriedades únicas das microalgas mostra-se uma promissora área de pesquisa. Desta forma, o objetivo do presente trabalho é avaliar a literatura referente à engenharia tecidual utilizando microalgas na produção de curativos cutâneos nos últimos anos através de uma revisão crítica. Para tanto, uma pesquisa no banco de dados Scopus foi realizada, utilizando as palavras-chave: “microalgae” e “skin”. Como resultado, foi obtida uma ampla revisão bibliográfica do potencial biotecnológico das microalgas em curativos cutâneos, que poderá direcionar estudos científicos sobre este tema.

    Introduction: A burn is a serious trauma with social, economic and public health repercussions that needs the attention of the government agencies. The treatment of these patients has always been a great challenge to the health team. Educational material is needed to teach dressing application in order to standardize the material and the technique and make the procedure safer for the patient and for the professional. Objective: Developing and validating a guide of the dressing technique used in burn patients. Method: An anteriority search was carried out but a similar guide was not found, a bibliographic survey was carried out in Pubmed and Scielo databases and in Google Scholar search engine. Standardized photographs were taken to illustrate the guide by showing step-by-step procedures. A professional designer diagrammed the Guide. Seven burn care experts did the Illustrated Guide content validation. The chosen method to validate was Delphi Technique, questionnaires were used to evaluate the following contents: Objective, Structure and Relevance of the study. Results: The objective item obtained 4.0 total IVC, 10.85 in Structure and 4.0 Relevance with global IVC of 0.99 reaching the validation goal and not requiring a new round of evaluation. The Illustrated Guide has 79 pages and 86 images. It was organized in 10 parts about the technique of burn dressing change. Topics such as material preparation, professional paramentation and dressing technique for each body region were addressed. Conclusion: An Illustrated Guide has been developed and validated with the step-by-step technique of burn dressing change.

    Traumatismos de veia cava inferior
    (Colégio Brasileiro de Cirurgiões, 2005-10-01) Costa, Cleinaldo de Almeida [UNIFESP]; Baptista-Silva, José Carlos Costa [UNIFESP]; Rodrigues, Lana Márcia Esteves; Mendonça, Fabiana Lo Presti; Paiva, Thiago Silveira; Burihan, Emil [UNIFESP]; Universidade do Estado do Amazonas; Universidade Federal de São Paulo (UNIFESP); SBACV; Universidade Federal do Amazonas Hospital Universitário Dona Francisca Mendes; Hospital da Força Aérea do Galeão; Universidade Federal do Amazonas Hospital Universitário Getúlio Vargas; Universidade Federal do Amazonas
    BACKGROUND: Injuries of inferior vena cava (IVC) require immediate and definitive action. Our objective is to evaluate the incidence, the clinical findings and the operative approach to IVC injuries. METHODS: We retrospectively studied 76 patients with IVC injuries treated in two Emergency Hospitals of Manaus, AM, Brazil, from January 1997 to July 2002. Mechanisms of injuries, mortality, hemodynamic status, penetrating abdominal trauma index (PATI), intraoperative findings and surgical approach were among assessed data. RESULTS: Fourty-nine patients (65%) had stab wounds, 26 (34%) gunshot wounds, and one had blunt abdominal trauma. Fourty-one (54%) patients survived. Almost all patients entered the emergency room awake, although 40% were hypotensive (systolic blood pressure < 70 mmHg), and the penetrating abdominal trauma index average was above 40. At laparotomy, active retroperitoneal bleeding or an expanding retroperitoneal hematoma were detected in all cases. Caval injury was retro-hepatic in 21 patients, and infrahepatic in the other 55. The prevailing surgical approach was lateral repair in 65 patients. Atrial-caval shunting was tried in six patients, with only three survivals. CONCLUSIONS: We concluded that IVC injury remains a highly lethal injury and there is a close relationship with urban violence. This study emphasizes that successful outcome depends on prompt volume restoration, avoidance of hypothermia and a stratified selective surgical approach.
