Biomateriais e terapia celular na reparação da cartilagem articular em equinos

Articular cartilage is the structure that coats the bone ends in regions where two bones are articulated, allowing movement. It has inefficient intrinsic and extrinsic mechanisms of repair, usually resulting in fibrocartilage formation after injury. Such repair have lower strength, stiffness and usability features when compared to hyaline cartilage. The mesenchymal stem cells have the potential to regenerate tissue without the production of scar, and because of this feature it is well studied. But to have its maximum chondrogenic potential, it is necessary to use scaffolds and growth factors. Biomaterials play the role of scaffold for the cells allowing them to become attached, grow and produce extracellular matrix, leading to formation of repair with hyaline cartilage. In this sense, the purpose of this study is to provide information on the various studies using cell therapy and / or biomaterials to produce hyaline cartilage

Considerações sobre o uso do piercing lingual

Objective: Investigated the consequences of tongue piercing in individuals from the city of Araraquara, São Paulo, Brazil. Methods: In Araraquara there are five piercing shops, but only two agreed to help the research by providing the contact information of customers who had had their tongues pierced. These customers were contacted by telephone. By the end of the research, the sample consisted of 100 individuals from both genders aged 18 years or more. Not all of them still had their tongue piercing. A form with six objective questions was used to collect information. The information was then analyzed by descriptive statistics. Results: From the 100 participants, 77 had been using tongue piercing for more than 6 months. It took less than 4 months for the tongue to heal. Sixty–eight individuals used oral rinses and of these, 19 also used painkillers. Only 11 individuals did not present symptoms after the first weeks using the piercing. On the other hand, 56 individuals reported complications such as increased salivation, speaking difficulties, gingival or mucosal traumas, dental fractures and eating difficulties. Conclusion: All these tongue-piercing complications justify efforts to inform the youth about the use of piercing in the oral cavity.

Análise comparativa de três técnicas cirúrgicas como tratamento da luxação coxofemoral

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...

Relações entre força muscular e composição corporal e regional em idosos

Exercise, in general have the ability to promote health, reduce loss of physical fitness, reduce declines in body composition and prevent disease, and promote improvements in athletic performance, and that's consensual today. Through analysis of body composition and physical fitness, you can diagnose the possible individuals at risk of developing diseases, and fractures caused by falls in the elderly. The DXA tests were used (densitometry by dual beam X-ray) to assess body composition and regional, 1 RM test to evaluate the maximum strength and girth measurements, diameters and skin folds in order to analyze the balance of power muscle with both body composition as regional. The results showed that the variance in bone mass between older content related to the change in the maximum muscular strength of the upper and lower limbs, but the force values are not related to increased muscle mass. The development of muscle strength fulfills a dual function in aging which is to maintain or reduce the rate of loss of lean body mass, and also so the body bone health

Efeito da aPDT na osseointegração de implantes em alvéolos contaminados

Objective: The aim of this study is to evaluate by histometric and immunohistochemistry analysis the effects of antimicrobial photodynamic therapy (aPDT) in alveolar prior to placement of mini-implants in animals with or without induced periodontal disease. Material and method: Thirty-two rats were used. Periodontal disease (PD) was induced by ligature in the lower left first molar. After 7 days of PD evolution, it was performed removal of the ligature and extraction of the left lower first molars in all animals. Thus, animals were divided into 2 groups (n=16) according to the treatments in the dental alveolus before immediate implant installation: MD (control) : mechanical debridement (MD), irrigation with 1 ml of saline solution followed by implant installation; aPDT- MD, irrigation with 1 ml of Toluidine Blue-O and low intensity laser (LLLT) and implant installation. Eight animals from each group were euthanized at 15 and 30 days after the installation of mini-implants. Specimens were processed for histologic, immunohistochemical and histometric analysis. The histometric data were processed for statistical analysis (Kruskall-Wallis and Dunn test; p <0.05). Result: In treatment analysis, results indicated that there was a greater BIC in implants installed in uncontaminated alveolus treated with a PDT ( p<0,05) and greater imuno-reactivity to OPG in bone issue treated with aPDT. Conclusion: The aPDT proved to be effective in bone loss control in no contaminated area and it has increased the bone loss and metabolic activity in alveolus irradiated prior to implant installation.

Aparelho extrabucal como recurso auxiliar para alinhamento e nivelamento no tratamento orto cirúrgico de má oclusão classe III esquelética

When well indicated, the orthodontic surgical approach is the ideal treatment mean for Skeletal Class III adult patients. To improve facial esthetic results from orthognatic surgery, the leveling and alignment of maxillary dental arch must be achieved with minimal inclination and projection or even retro-inclination of anterior upper teeth. During a pre-surgical phase of 12 months, headgear bilateral force of 150 g/F was applied to the upper molars of a 22 years old male compliant patient with Class III skeletal malocclusion, to provide an upper teeth control of mesial tipping and projection during alignment and leveling. The ideal occlusal parameters required for surgical procedure were achieved without dental extractions permitting a total treatment period of 37 months. The outcomes remained stable over 3 years follow up after the removal of the appliance. The results indicate that, although headgear use depends greatly on patient compliance, when well indicated it is an interesting alternativetopromote dentaldecompensationon pre-surgical period, in order to allow surgical correction of skeletal Class III malocclusion.
