Associação fitoterápica no tratamento de feridas cutâneas induzidas em equinos

The efficiency of the topical use of a commercial product constituted by a herbal combination on the healing evolution of equine induced wounds was studied. A skin lesion in the shape of a square with 5cm sides was surgically produced on both sides of the buttocks of eight adult horses. One side was considered control and another one treated. Both control and treated sides were rinsed with water and neutral soap. Additionally, the wound on the treated side received the topical treatment with the herbal combination. Macroscopic and microscopic healing evolution of the wounds was evaluated and their areas were determined during the experimental period. There was statistical difference between wound areas. At the last evaluation, the average area of the control side was 0.70cm² and of the treated side was 1.23cm². The contraction of scar observed at 77 days was 97.57% for the control side and 95.59% for the treated side.

Caracterização de lesões desportivas no basquetebol

INTRODUCTION: Basketball is characterized with high injury rate. In the literature it's not defined whether or not there are differences between the sexes. OBJECTIVE: Characterize and analyze the incidence of athletic injuries in basketball players, comparing the sexes. MATERIALS AND METHODS: Fifteen under-23 category athletes of each sex were interviewed with the reported morbidity inquire. RESULTS: The age of the female and male teams, in average, was 18 ± 0.65 and 18.20 ± 1.57 years respectively. The male team had more injuries than the female one (respectively 2.6 ± 1.45 against 1.2 ± 1.18, p < 0.05). The joint damage was the most common injury in the male team, representing 58.97%, and the second most common in the female team (33.33%). The lower limbs were the most common injured sites (80.95% in the female and 69.23% in the male). The most frequent injury mechanism in the male team was the landing (43.59%), and in the female was the vertical jump (28.57%). In both teams the most injuries occurred during the training (61.9% in the female and 71.8% in the male). The absence was necessary in 47.62% (female) and 56.41% (male). Great part of the athletes didn't received any treatment (61.9% and 51.28% in the female and male team respectively). The return to the activities was mostly symptomatic, in both female and male team (85.71% and 84.62% respectively). CONCLUSION: The incidence of injuries in basketball is higher in the lower limbs. The male team is more likely to suffer injuries, and the main injury mechanisms were different between male and female team.

Divergências entre histórico da consulta e diagnóstico médico de agressões físicas registradas nos prontuários de uma unidade de urgência e emergência

There can be several indicators of violence in society. However, in no other health unit such violence acquires visibility as in emergency. This study aimed to examine whether there is divergence between the history of medical consultation and diagnosis of physical aggressions in the emergency unit. A cross-sectional study was conducted in an emergency unit in the city of Araçatuba, state of São Paulo, Brazil, based on medical records, considering data on patients, lesions, history, diagnosis and treatment. Out of 133,537 visits, only 153 were recorded as physical aggressions, and 161 informed violence in the history of the consultation; 59.6% were male, 60.6% were between 20 and 44 years old. Excoriations, pain and injury predominated. There were no associations between state violence in the diagnosis and the characteristics of patients and visits (schedule, routing, gender, age). The conclusion is that in most cases violence reported in the history of the consultation was not mentioned in the diagnosis of injuries. The characteristics of care and patients were not related to the fact that professionals diagnosed the case as violence.

Uso de células-tronco para o tratamento de tendinite em eqüinos

Brazil has the fourth largest horse herd in the world, this is due the recognition and appreciation that the different equestrian games are having within the country. Injuries of the tendon, especially in the digital flexor tendon, are the main cause of athletic life reduction among horses. The treatment of tendinitis in horses seeks full recovery of the damage tissue reestablishing the function previously lost, however conventional treatments have proven to be ineffective when considered the quality of the scar tissue and the rate of recurrence. Due to this, the use of adult stem cells to the treatment of musculoskeletal injuries of horses has been studied for some time. This method of treatment consists of aspiration of bone marrow or removal of subcutaneous fat tissue and implantation of these cells in the injured tissue. After obtaining the bone marrow the implantation can be performed with total bone marrow, with the mononuclear fraction of MSC or with cells cultured in vitro. From the fat tissue is used the stromal vascular fraction obtained by collagenase digestion, followed or not by cell culture. According to some studies, cell therapy with material obtained from bone marrow or adipose tissue has shown to be viable, given that these materials are abundant in repair components such as mesenchymal stem cells (MSC), growth factors and other components of the collagen matrix. Several studies using both types of cells have shown great potential and promising clinical results. However, knowledge of the biology and characterization of these cells remain largely unknown, and therefore is needed great care and caution when using stem cells for the treatment of musculoskeletal disorders in horses

Laserterapia em lesões de coluna na Medicina Veterinária

Lasertherapy is a method of non-pharmacological treatment and surgery that can be used in several injuries and in various tissues, from bone fractures to tendonitis, skin wounds and damaged nerves, permitting the recovery of these structures and their functions without causing any side effects. Laser therapy aims to restore patients that suffered various injuries, such as bone fracture, inflammation, edema, tendon rupture, spinal cord injury, among others, without invasive intervention, and the results obtained in several studies and case reports have proven the high potential of this therapy to become an official treatment of various pathological changes

Perfil epidemiológico dos pacientes internados na unidade de tratamento de queimaduras do Hospital Estadual de Bauru

Burns are frequent accidents, and they are among the major causes of morbidity and mortality in our society. In Brazil, statistical data on such lesions are relatively scarce, and they are concentrated in a few treatment centers. Data on such accidents allow for specific care to be timely and properly taken in order to provide patients with a better prognosis, in addition to enabling the development of prevention programs as well as fire-prevention safety laws. To characterize the epidemiological profile of users at the Burn Treatment Unit of Bauru State Hospital. Collection of epidemiological data through the e-pront system and from charts of burned inpatients from April 2005 to April 2010. During the studied period, 906 hospitalizations of burned patients occurred, with an annual average of 181.2 individuals. Their mean age was 28.4 years, with a predominance of males. The mean hospitalization period was of 27.6 days, with a median of 16 days and a maximum of 216 days; 14.7% developed to death, with the highest mortality rate in the first two weeks of hospitalization. Second-degree burns were the most frequent; 36.8% of the patients burned less than 10% of their body surface, and there was a gradual frequency reduction when a larger burned surface was taken into account; the greater the affected areas, the higher the number of deaths; 91% resulted from thermal agents, 6% from electric and 2% from chemical agents; scalding was the major cause among all agents, followed by alcohol associated with fire and direct flame. The major area affected areas were the upper limbs. The study shows the need for educational and preventive measures, particularly for the young adult population, by means of educational programs and prevention campaigns

Desenvolvimento e caracterização de microemulsões contendo fluconazol para o tratamento da Leishmaniose tegumentar

A leishmaniose tegumentar é causada pela picada da fêmea dos insetos flebotomíneos. As lesões podem evoluir de pápulas para úlceras, que apresentam fundo granuloso e bordas infiltradas, as quais são indolores, podendo ser únicas ou múltiplas. Trata-se de uma doença negligenciada e o investimento em seu tratamento é desprezível. Até hoje, são empregados no tratamento medicamentos a base de antimonial pentavalente, além de outros fármacos como pentamidina, anfotericina B, paromomicina, imidazoquinolina, antifúngicos, como o fluconazol (FLU). As microemulsões (MEs) melhorarem a solubilidade e estabilidade dos fármacos, além de proporcionarem ação prolongada, vetorização diferenciada para determinados tecidos ou órgãos do organismo. Este trabalho teve como objetivos desenvolver e caracterizar MEs contendo FLU, caracterizar estruturalmente por meio de análises de microscopia de luz polarizada, análise do tamanho das gotículas, análise do perfil de textura e avaliação da bioadesão. Para o estudo de estabilidade foram empregados ensaios de avaliação visual e determinação do pH. Quanto aos ensaios biológicos in vitro, foram realizados ensaios colorimétricos das amostras visando verificar se o sistema desenvolvido permite a potencialização do poder leishmanicida do FLU contra as formas promastigotas da Leishmania amazonensis. Pelo diagrama de fases observou fases líquido-cristalinas confirmadas pela microscopia de luz polarizada, e foram selecionadas três formulações: uma SLT e duas SVT. Todos os ensaios de caracterização estrutural para a F2 sofreu variação quando acrescentou o fármaco, exceto para o potencial zeta, difração de raios X e bioadesão. Não houve alteração no ensaio estabilidade físico-química no período analisado. Os ensaios biológicos in vitro evidenciaram, nas condições metodológicas, inefetividade do sistema contra as formas promastigotas de L. amazonensis

Terapia fotodinâmica e luz branca: aspectos analíticos e perspectivas da viabilidade do tratamento

Photodynamic Therapy (PDT) is a technique used to treat several types of lesions, such as cancer, microbial control, and esthetic dentistry cases. The performance of PDT involves the use of a photosensitizer (PS), which mainly will be located in cancer cells and is irradiated with visible light. This process, when it occurs in the presence of oxygen triggers the formation of reactive oxygen species that are cytotoxic to cells. These species cause cell death and subsequent tumor necrosis. The use of white light as a light source for multispectral Photodynamic Therapy and its consequences to the photodynamic effect is not yet completely established, and therefore there is interest in studying the parameters involved for analyzing the best conditions for applying treatment. The wavelength is crucial to improve the therapeutic effect, since both the optical properties of the biological tissue as the PS depend on these parameters. For FS studied in this work (Photogem®) are most often used wavelengths in the red region, due to their larger penetration depth in biological tissue. Thus, the light source becomes a fundamental aspect, their choice depends on the specific application and is based on the tumor location, light dose to be delivered and FS chosen. Despite all the advantages presented by lasers, the fact of having an emission spectrum essentially monochrome makes only one possible transition possible for the absorption of FS is used. Therefore, more extensive light sources such as light emitting diodes (LED), could be better used in some cases the laser, with the additional advantage of a reduced cost. Therefore, the choice of the white LED comes from an emission spectrum that still wider LED colors defined by allowing greater use of the several absorption bands and with varying depths of operation, according to the wavelength...

Estudo citogenético em neoplasias e lesões proliferativas ósseas

A busca pela identificação de fatores que possam apontar o diagnóstico, a resposta terapêutica e sobrevida dos pacientes portadores de neoplasias ósseas tem sido incessante. Poderá ser de grande valia na escolha da proposta terapêutica presumir a agressividade tumoral, capacidade de invasão tecidual, propensão ao desenvolvimento de metástases e resposta ao tratamento. As neoplasias ósseas constituem um grupo heterogêneo de tumores, considerando-se os sítios anatômicos e a etiologia. Existe uma grande dificuldade para se estabelecer o prognóstico nestas patologias. Estudos citogenéticos possibilitam um melhor conhecimento antecipado dessas doenças. Embora fatores ambientais e dietéticos contribuam para a etiologia do câncer, as neoplasias se originam de um processo de múltiplos passos envolvendo alterações de genes e seleção clonal da progênie variante. Estas mutações ocorrem em classes de genes reguladores da proliferação celular como os oncogenes, genes supressores de tumor, fatores de crescimento, vias de sinalização e genes de reparo de DNA. Este projeto tem por objetivo detectar e descrever alterações cromossômicas consistentes e recorrentes através da utilização da citogenética clássica e o seu envolvimento no prognóstico em neoplasias ósseas, de pacientes do Hospital das Clínicas da Faculdade de Medicina de Botucatu, UNESP. Os conhecimentos sobre a biologia molecular melhoram o entendimento sobre os múltiplos aspectos da carcinogênese. Entretanto, embora, as perspectivas permaneçam, não houve até agora benefícios significativos em termos de prevenção, diagnóstico tratamento e seguimento dos pacientes com lesões ósseas. Este projeto visa estudos na tentativa de contribuir para um melhor entendimento e, por conseqüência, gerar dados para posteriores empregos em terapias mais eficazes para melhorar as taxas de sobrevida e beneficiar maior número de pacientes com neoplasias ósseas

Programação linear no planejamento do tratamento de câncer por radiocirurgia

Medical Physics has been reaching an important role among several lines in Science, providing means for the improvement of several theories and procedures. Currently, its main application is related with the use of ionizing radiations, specially, in treatment procedures such as Radiotherapy. Radiosurgery is a Radiotherapy technique which consists in administering a single tumoricidal dose of radiation exclusively to the tumorous lesion. It becomes then an interesting alternative to surgical treatment, mainly in cerebral metastases, which are the most frequent cerebral tumors in the central nervous system. The radio neurosurgical team works out a planning for the Radiosurgery treatment, aiming for obtaining an appropriate ideal treatment for each case. For the working out of this treatment planning, Computed Tomography images of the region to be treated are obtained, digitalized and later, fused with nuclear magnetic resonance images. Through these images, critical structures, organs at risk and lesions are localized. After this, calculations are made to determine three-dimensional positions of isocenters, isodose curves, prescribed dose, collimators sizes, position, numbers and respective weight of isocentric conformal fields, and others. The treatment planning is commonly based in desired levels of dose for specific types of tumors and organs at risk concerning the irradiated region. Theses levels of dose are chosen in a way that a high probability of cure may be achieved and meanwhile, that the probability of complications, in whichever organ at risk, may be minimal. Thus, many researches have been carried out, showing that mathematical techniques may help to obtain an optimal planning for the treatment of cerebral metastases. Among the methods of optimization in the study...(Complete abstract click electronic access below)
