A articulação coxofemoral em cães tem sido, ao longo dos anos, a mais frequentemente lesionada, principalmente de forma traumática, por acidentes automobilísticos ou atropelamentos. O tratamento de escolha para resolver a luxação coxofemoral é o método por redução fechada. Entretanto, na generalidade dos casos, esta técnica não se mostra suficiente para correta estabilização articular, pois há outras afecções envolvidas ou a cronicidade da lesão impede uma manobra efetiva. Sendo assim, recorre-se à cirurgia para correção da luxação. Diversas são as técnicas cirúrgicas praticadas para tal enfermidade. O pino transarticular é um procedimento usado há muito tempo. Essa técnica requer aceitável coaptação articular e é recomendada em casos de grave lesão capsular. Porém, seu uso é discutível por causar lesões degenerativas na articulação ou migração do implante. Dessa forma, a sutura extra-articular vem sendo estudada por apresentar uma estratégia alternativa que não prejudica as estruturas da região operada e por vir demonstrando resultados satisfatórios. Nas situações de luxação recorrente, necrose asséptica da cabeça do fêmur e fraturas de cabeça e colo femoral ou acetabular, a colocefalectomia deve ser empregada. Considerada como técnica de salvamento, esta pode ser utilizada após insucesso dos outros métodos para correção da articulação coxofemoral. Vários estudos foram selecionados para que seus resultados fossem analisados. Assim conclui-se que não existe uma técnica ideal. Todas apresentam adequada congruência articular, porém os implantes metálicos exibem grandes possibilidades de complicação pós-operatória, a sutura extra articular fornece boa estabilidade e poucas lesões locais e a colocefalectomia fica sendo como o último recurso, caso ocorra falha...

Os usuários de medicamentos muitas vezes optam não pelo medicamento industrializado, que já está ali pronto para ser vendido, e sim o medicamento manipulado, feito de forma individualizada, mas que contém o mesmo fármaco, ação, efeitos adversos. Por essa razão, esse trabalho buscou implantar bulas aos medicamentos manipulados na Farmácia-Escola Prof. Dr. Antonio Alonso Martinez da UNESP de Araraquara, da Faculdade de Ciências Farmacêuticas, de modo a prestar informações e garantir uma farmacoterapia adequada a seus clientes. Com base na Lista de Medicamentos Manipulados pela Farmácia Escola, foram selecionados todos os medicamentos alopáticos e suas associações, para uma pesquisa em referências bibliográficas confiáveis, de modo a usar o conteúdo pesquisado para a confecção das bulas. O trabalho concluído resultou em 30 bulas, que serão impressas e entregues juntamente com os medicamentos manipulados, de forma individualizada.

Eventos adversos a medicamentos (EAM) ainda são uma das principais limitações nos serviços de cuidados com a saúde, causando risco aos pacientes, além de grande impacto econômico. Assim, fazem-se necessários métodos de identificação de eventos adversos mais eficazes que a tradicional notificação espontânea, a qual revela apenas 5% do total de eventos. A utilização de critérios rastreadores (ou trigger tools), elaborados pelo Institute for Healthcare Improvement, tem se mostrado como a alternativa mais válida e eficiente para a triagem dos EAM. Com o objetivo principal de identificar os principais eventos adversos e medicamentos envolvidos, uma seleção de três critérios rastreadores foi utilizada, a saber: INR (razão normalizada internacional) > 6, WBC (contagem de leucócitos) < 3000/mm³ ou registros de episódios de sedação excessiva, letargia ou queda. Informações sobre os rastreadores foram coletadas e analisadas a partir dos prontuários de pacientes internados no Hospital Estadual Américo Brasiliense internados, de novembro de 2011 a janeiro de 2012 e maio a julho de 2012, a fim de se confirmar a ocorrência de evento adverso. Foram analisados prontuários referentes a 3318 hospitalizações, nas quais foram detectados 69 eventos adversos, 49 dos quais foram causados por apenas quatro das 12 classes de medicamentos envolvidos em algum EAM: anticoagulantes orais, relacionados ao rastreador INR>6 (eficácia = 0,75), sedativos e antipsicóticos, relacionados ao rastreador de sedação excessiva, letargia ou queda (eficácia = 0,52), e antivirais, relacionados ao rastreador WBC<3000 (eficácia = 0,48). Quando os rastreadores eram acionados e não estavam relacionados a EAM, os fatores de confusão mais recorrentes foram: torpor secundário ao quadro clínico, acidentes não relacionados ao medicamento e pacientes propositalmente em regime de sedação. Apesar de valores-limite menos radicais poderem aumentar a ...

The aim of this research is to analyze the extension of changes in technological strategies of a group of Brazilian pharmaceutical companies, which we believe were induced by transformations in the institutional environment during the 1990s. Major institutional changes, such as the enacting of laws that recognized drug patents rights and fostered generic drugs market, have strengthened the market insertion and competitive position of these companies, what would enable an increase in research and development efforts in Brazil. In addition to the literature on technology strategy and drug industry, this study was based on interviews with six Brazilian pharmaceutical companies, all of which were ranked among the top national companies in the industry and have been considered in previous studies particularly active in the process of changing technological strategies. This research confirmed a significant intensification of technology efforts carried out by Brazilian drug companies. Nevertheless, the R&D intensity is still far below the global pattern and innovative impacts are slight.

This work had aim to present two clinical cases with open bite Class II malocclusion that treated in the phase of the mixed dentition with the modified Thurow appliance and in the permanent dentition with fixed appliance. The dentoskeletal effects of these appliances were carefully analyzed with the aid of metallic implants inserted in both maxilla and mandible. The correction of the malocclusion and the improvement of the skeletal, dental and facial relationship were observed in both cases. The modified Thurow appliance followed by fixed-appliance as a two-phase treatment protocol revealed to be an effective treatment approach for the two young people that initially presented a Class II division 1 malocclusion associated to anterior open bite presented.

The purpose of this literature review is to present the state-of-the-art on the application of tissue engineering techniques in sinus lifts procedures, reporting the influence of these techniques in increasing bone height and volume in the maxillary sinus, and the osseointegration of the implants installed in the grafted areas. PubMed and Scopus databases were searched using the keywords “scaffold” OR “engineered tissue” AND “sinus augmention” OR “sinus floor elevation”. In the initial search 463 articles were selected, of which 19 were selected abstracts reading, with nine papers selected by the end, for evaluation of the application of tissue engineering techniques in sinus lift procedures. Despite the positive results of tissue engineering procedures in sinus floor elevation reported in the selected articles, further studies are still needed, for a better standardization of experimental models and materials used, leading to definitive conclusions about the effects of the application of tissue engineering procedures on bone formation in maxillary sinus lifting procedures.

The early tooth loss and periodontal disease often leave inadequate bone volume for installation of osseointegrated implants. The autogenous bone graft is considered the gold standard for reconstruction of residual bone defects. Some surgical techniques can be performed, including extra or intraoral donor sites depending on the degree of bone loss, depending on surgical-prosthetic planning and general condition of the patient. The intraoral bone grafts offer a safe option to rebuilt bone volume in smaller rehabilitations, with low morbidity and minimal postoperative discomfort. Among the possible donor sites, the mandibular ramus and body, which offer predominantly cortical bone, and the chin area, which offers corticomedullary bone tissue, can be harvested. The graft will be suitable both in quantity and quality, preserving the capacity of osteogenesis, osteoinduction and osteoconduction, which differentiate autogenous grafts from other biomaterials. The aim of this study was to report a clinical case in which the mandibular ramus graft was used for total reconstruction of an edentulous maxilla, showing that even large areas can be reconstructed with grafts from intraoral origin. All the steps that allowed the complete reconstruction of the maxilla done by an intraoral donor area are listed in the text, culminating in an extremely satisfactory clinical result.

The bone resorption in the anterior maxilla, due to its aesthetic importance, can be considered one of the challenges in implant dentistry. Autogenous bone graft is the most indicated bone augmentation procedure, aiming an implant supported rehabilitation.. Alternatively, some other graft procedures can be done with homogenous and xenogenous bone graft, biomaterials and different associations. Additionally to the mentioned biomaterials, the bone morphogenetic protein (BMP), specially the rhBMP-2, which was characterized as a bone osteoinductor, and consecutively, a potential autogenous graft substitute, with previsibility and no necessity of association to other biomaterial. The objective of this study is to present a single case using the rhBMP-2 for bone augmentation.

The objective of this study was to evaluate the remodeling of autologous and homologous bone grafts in humans, using tomographic images. For this, CT images from 10 patients (5 treated with autologous bone grafts and 5 treated with homologous bone grafts), made previously to the grafting procedures, and 14 and 180 days post operatory were evaluated regarding to bone height, width, and density, in a total of 19 bone blocks, 10 homologous and 9 autologous. Results showed similarities between the two tested materials regarding bone width and density. It can be concluded that the homologous bone presented, in a tomographic approach, after 180 days of follow-up, characteristics which can corroborate its use as a bone graft material, providing and sustaining a good bone volume for oral rehabilitation with dental implants.

The correction of bone defects is the restoration of lost structures which can be replaced by alloplastic implants or bone grafts. Due to the known disadvantages of removal of autogenous grafts, most researches in dentistry aim to develop alloplastic or non-alloplastic materials able to replace bone without these limitations. Beta-Tricalcium Phosphate (β-TCP) is a synthetic granular bone substitute, biocompatible, osteoconductive, which can be used in the alveolar reconstruction. In this work, we perform a literature review on the β-TCP characteristics and discuss its application in dentistry.

Immediate functioning of osseointegrated implants has been widely employed in edentulous patients due to its safety and high predictability. However, viability and success of immediate-loaded implants is defined by factors such as number of implants, distribution and splinting, as well as reduction of oblique loads and excessive occlusal contacts. The indirect composite resin-modified glass enable building of a highly aesthetic prosthesis, combining satisfactory resistance and better force dissipation on occlusal loading. This article describes a resin composite, mandibular fixed prosthesis on osseointegrated implants in immediate function.

Osteodistraction is a clinical reality, available in the last decades for the resolution of large bone deficiencies, in cases that there are pre-existing, but misplaced implants and teeth. The aims of thearticle is to present a case report in which a new possibility for bone distraction, based on tooth-implant bone distractors, made from standard orthodontic expansion-screws, was used in an area where there was an extensive need of alveolar bone and aesthetical recovery, allied to teeth and dental implant misplacement. This technique presented good clinical results, associated to effective simplicity and low cost, becoming viable clinical solution for bone tissue augmentation and aesthetical optimization. In resume, it is possible to say that the suggested technique achieved its objectives, improving the hard and soft tissue profile, whilst allowing completion of oral rehabilitation.
