Bone healing in surgically created defects treated with either bioactive glass particles, a calcium sulfate barrier, or a combination of both materials: A histological and histometric study in rat tibias

Objective: The purpose of this study was to histologically analyze the influence of bioactive glass and/or a calcium sulfate barrier on bone healing in surgically created defects in rat tibias. Material and methods: Sixty-four rats were divided into 4 groups: C (control), CS (calcium sulfate), BG (bioactive glass), and BG/CS (bioactive glass/calcium sulfate). A surgical defect was created in the tibia of each animal. In Group CS, a calcium sulfate barrier was placed to cover the defect. In Group BG the defect was filled with bioactive glass. In Group BG/CS, it was filled with bioactive glass and protected by a barrier of calcium sulfate. Animals were sacrificed at 10 or 30 days post-operative. The formation of new bone in the cortical area of the defect was evaluated histomorphometrically. Results: At 10 days post-operative, Group C presented significantly more bone formation than Groups CS, BG, or BG/CS. No statistically significant differences were found between the experimental groups. At 30 days post-operative, Group C demonstrated significantly more bone formation than the experimental groups. Groups CS and BG/CS showed significantly more bone formation than Group BG. No statistically significant differences were found between Group CS and BG/CS. Conclusions: (a) the control groups had significantly more bone formation than the experimental groups; (b) at 10 days post-operative, no significant differences were found between any of the experimental groups; and (c) at 30 days post-operative, the groups with a calcium sulfate barrier had significantly more bone formation than the group that used bioactive glass only.

Atendimento psicoterapêutico para crianças vítimas de violência sexual: projeto Sarauzinho

This experiment report refers to the project named “Sarauzinho”, which is linked to the extension “Workshops of Psychoanalysis and Artistics Gatherings” project. “Sarauzinho” was a partnership between UNESP and CREAS, created with the aim to assist children victims of sexual violence though a playful and artistic method and to implement a psychoanalytic listening of demands that appeared during the working group implementation. At the same time, the parents/responsible person who took the children to the meetings also received psychotherapeutic service at the waiting room, in an operative group format with psychoanalytic listening. The project has happened in 11 sessions (once a week, two hours each), with 4 kids and 4 caregivers participating. The service for the kids was organized in workshop models (open and free) and in little gatherings, with preprogrammed contents (playful and artistic). The initiative was inspired by the “Green houses”, a creation of the French psychoanalyst Françoise Dolto, and by the Museum “Imagens do Inconsciente do Centro Psiquiátrico Pedro II”, in Nise da Silveira, Rio de Janeiro city. This university extension activity has enabled the students to access some of the children’s traumas, as well as to obtain a better understanding of an infantile group psychotherapeutic service, with psychoanalytic listening. Besides, it has provided a playful and artistic environment to listen to the children and enable them to create new meanings of their traumas. For the adult participants, the meetings were moments to talk about their anxieties and to receive new guidance and instructions about their children’s education, especially about sexuality. The results, either related to the children’s meeting, as to the adult’s meeting, were favorable to the continuity of the project.

Perioperative fluid therapy: a statement from the international fluid optimization group

Perioperative fluid therapy remains a highly debated topic. Its purpose is to maintain or restore effective circulating blood volume during the immediate perioperative period. Maintaining effective circulating blood volume and pressure are key components of assuring adequate organ perfusion while avoiding the risks associated with either organ hypo- or hyperperfusion. Relative to perioperative fluid therapy, three inescapable conclusions exist: overhydration is bad, underhydration is bad, and what we assume about the fluid status of our patients may be incorrect. There is wide variability of practice, both between individuals and institutions. The aims of this paper are to clearly define the risks and benefits of fluid choices within the perioperative space, to describe current evidence-based methodologies for their administration, and ultimately to reduce the variability with which perioperative fluids are administered. Based on the abovementioned acknowledgements, a group of 72 researchers, well known within the field of fluid resuscitation, were invited, via email, to attend a meeting that was held in Chicago in 2011 to discuss perioperative fluid therapy. From the 72 invitees, 14 researchers representing 7 countries attended, and thus, the international Fluid Optimization Group (FOG) came into existence. These researches, working collaboratively, have reviewed the data from 162 different fluid resuscitation papers including both operative and intensive care unit populations. This manuscript is the result of 3 years of evidence-based, discussions, analysis, and synthesis of the currently known risks and benefits of individual fluids and the best methods for administering them. The results of this review paper provide an overview of the components of an effective perioperative fluid administration plan and address both the physiologic principles and outcomes of fluid administration. We recommend that both perioperative fluid choice and therapy be individualized. Patients should receive fluid therapy guided by predefined physiologic targets. Specifically, fluids should be administered when patients require augmentation of their perfusion and are also volume responsive. This paper provides a general approach to fluid therapy and practical recommendations.
