    Introduction: The analysis of gingival fluid can be used to determine specific markers of systemic diseases, its relation to periodontal disease, making the dental surgeon a health agent, concerned not only with oral problems, but also with systemic pathologies, acting in the prevention. A reliable and accessible device for this analysis is necessary. Objective: Develop and submit for patent registration a device for collection of gingival fluid. Methods: An antecedent search was carried out, which included documents that corresponded in part or in full with the subject of interest and had, as source, international databases (Espacenet, USPTO, WIPO, SIPO and JPO) and the bank of the INPI, as well as the PatBase software. It was verified the existence of 5 documents that were classified and evaluated as to their relevance, low, medium or high, according to criteria defined by the Nucleus of Technological Invention of the Federal University of São Paulo (NIT-UNIFESP). Result: A design and prototype of a gingival fluid collection device was developed and the application of the patent was submitted to NIT-UNIFESP. Conclusion: Based on the clinical needs and devices already developed, was sent for the patent registration a new device for collecting gingival fluid.

    Infusion pumps and red blood cell damage in transfusion therapy: an integrative revision of the academic literature
    (Wiley, 2016) Wilson, Ana Maria Miranda Martins; Peterlini, Maria Angélica Sorgini [UNIFESP]; Pedreira, Mavilde da Luz Gonçalves [UNIFESP]
    Objectives: to obtain information from scientific literature concerning infusion pumps used in administering erythrocyte (red blood cells) and to evaluate the implications in the practical use of this equipment by nurses when conducting transfusions. Method: an integrative revision of the following scientific databases: Pubmed/Medline, Scopus, the Virtual Library for Health, SciELO, Web of Science and Cochrane. The following descriptors were used: "infusion pumps", "blood transfusion", "transfused erythrocyte" and "hemolyis". There were no restrictions on the scope of the initial data and it was finalized in December 2014. 17 articles were identified in accordance with the inclusion and exclusion criteria. Results: all of the publications included in the studies were experimental in vitro and covered the use of infusion pumps in transfusion therapy. A summary of the data was presented in a synoptic chart and an analysis of it generated the following categories: cellular damage and the infusion mechanism. Conclusion: infusion pumps can be harmful to erythrocytes based on the infusion mechanism that is used, as the linear peristaltic pump is more likely to cause hemolysis. Cellular damage is related to the plasmatic liberation of markers that largely dominate free hemoglobin and potassium. We reiterate the need for further research and technological investments to guide the development of protocols that promote safe practices and that can contribute to future clinical studies.

    Lâmina De Serra Óssea Para Obtenção De Enxerto Autólogo Nas Osteotomias Do Joelho.
    (Universidade Federal de São Paulo (UNIFESP), 2018-08-17) Sobral, Helio Steponavicius [UNIFESP]; Aloise, Antonio Carlos [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Introduction: Young Patients With Varus Knee Osteoarthritis Has Been Increasingly Treated With Osteotomy Surgeries. Open Wedge High Tibial Osteotomies Present Lower Complication Rates And Greater Technical Ease. There Are Several Options Of Grafts And Fixation Methods Available. The Gold Standard Remains Autogenous Bone Graft, However The Morbidity Of The Donor Site Still Lead To Patient Complains. Objective: To Create A Device To Remove Bone From The Same Surgical Site, Using The Graft To Fill The Wedge Space. Methods: Review Of Existing Patents In The Main National (Inpi) And International Databases (Epo, Uspto, Espacenet, Wipo, Google Patent Search And Jpo) Was Done. Models For Validation Of The Concept, Application And Functionality Of The Device Were Developed With The Use Of Design Thinking. The Prototype Consists Of Two Parts: The Saw Blade And The Guide For Opening The Wedge And Stabilizing The Blade. The Industrial Design And Final Version Of The Device Were Made. Results: One Patent Was Found In The

    Proximal tibial reconstruction with auto transplantation of the fibular growth plate: two case reports, describing the surgical technique
    (Springer International Publishing Ag, 2016) Ribeiro Baptista, Pedro Pericles; Bannwart, Cassiano Leao; Ribeiro Batista, Felipe Augusto; Bellan, Davi Gabriel [UNIFESP]
    Introduction: Tumors of the proximal tibia, in children, can affect the growth plate and pose a challenge to further reconstruction of the bone defects resulting from tumor resection. Reconstruction methods do not always compensate the potential for bone growth in this segment. We present a new surgical technique of bone reconstruction, based on the transposition of the ipsilateral fibula with its growth plate and the use of an internal sliding fixation device, without need for microsurgical technique. Case description: We report two patients with osteosarcoma of the proximal tibia affecting the growth cartilage who were treated with the new technique. Discussion and Evaluation: In both cases, bone healing, hypertrophy and longitudinal growth of the transposed fibula were documented. Conclusions: This new technique preserves the blood supply of the auto-transplanted bone segment, maintaining physeal growth potential, with no need for microsurgery. The implant allows longitudinal bone growth, which was radiographically confirmed.
