Full textEste trabalho pretende ser um resumo do que na actualidade se debate a nível científico e clínico acerca da fisiopatologia, diagnóstico, tratamento, prognóstico e prevenção de uma patologia muito grave e ainda muito pouco compreendida como é a laminite em equinos. Sendo uma patologia algo frequente e debilitante, com prognóstico de reservado a mau, e embora existam há muitos anos tentativas da comunidade científica em explicar a laminite, de maneira a melhorar o tratamento e a prevenção, estes estudos têm sido muitas vezes contraditórios. Apesar de ter já existido uma grande evolução no estudo desta patologia no entanto o factor desencadeante não foi ainda comprovado cientificamente apesar de existirem algumas teorias a seu respeito. Serão apresentados dois casos clínicos que ocorreram durante o meu período de estágio, com os quais me apercebi não só das dificuldades atrás referidas mas também de outras associadas à clínica de equinos em Portugal, sendo a mais visível a vertente económica.

Full textA Osteoartrite (OA) é a principal causa de claudicação no cavalo de desporto e lazer, sendo uma afecção que tem grandes repercussões económicas. Este trabalho descreve algumas das características importantes da estrutura articular, bem como da sua fisiologia. Define a OA e todas as estruturas envolvidas no seu processo. Os mecanismos fisiopatológicos põem em evidência os factores de risco em causa e que determinam todo o processo de degradação articular. São descritos os vários meios de diagnóstico utilizados, quer os convencionais, quer as recentes técnicas imagiológicas (ressonância magnética, tomografia computadorizada e cintigrafia nuclear) quer ainda os biomarcadores do metabolismo da cartilagem articular e osso. A abordagem terapêutica é diversa incluindo os anti-inflamatórios não esteróides, os corticosteróides, os glicosaminoglicanos polisulfatados, o hialuronato de sódio, o pentosan polisulfato e o ácido tiludrónico, com o objectivo de travar a progressão da doença articular. Também são abordadas novas formas alternativas de tratamento da OA, como a terapia por meio de ondas de choque, a utilização de células estaminais mesenquimatosas e a terapia genética. Este trabalho é complementado pela descrição de dois casos clínicos, onde são abordados o diagnóstico e respectivo tratamento.
ABSTRACT - The Osteoarthritis (OA) is the main cause of lameness in the sport and leisure horse, being an affection with great economic evolvement. This work describes the main characteristics of the joint structure, as well as its physiology. It defines the OA and all the involved structures in its process. It’s physiopathology puts in evidence all the risk factors and all the process of joint degradation associated. Diagnosis methods are mentioned, not only the conventional ones, but also the recent imaging techniques (magnetic resonance imaging, computed tomography and nuclear scintigraphy) and the use of the bone and cartilage biomarkers. Diverse types of treatment are used, as it is the case of non-steroidal anti-inflammatory, corticosteroids, polysulfated glycosaminoglycan, hyaluronan, pentosan polysulfate and acid tiludronic, drugs, achieving to decrease the progression of the joint disease.

Full textIn order to evaluate the effect of supplementation with gamma-oryzanol in horses undergoing aerobic exercise were used ten Purebred Arabian horses, geldings, mean age 35±8.15 months and mean weight of 375±22.78 kg at the beginning of the experimental period, divided into two groups of five animals each, named \"gamma\" and \"control\" groups. The experiment was conducted at the Laboratório de Pesquisa em Alimentação e Fisiologia do Exercício de Equinos (LABEQUI), belonging to FMVZ-USP, at Campus Administrativo de Pirassununga, São Paulo, adopting individual daily consumption of 2% of body weight, based on dry matter, 50% of forage composed of grass hay and 50% commercial concentrate. In each meal, the animals received fifty milliliters of vegetable oil, and only the gamma group received the gamma-oryzanol (ten grams daily). Both groups were trained in electronic walker for sixty minutes at a maximum speed of 12 km/h, five times a week. During the trial period of six months, the horses were evaluated monthly to weight gain, body condition score, and plasma lipids (total cholesterol and HDL-C, VLDL-C, LDL-C, and triglycerides). The every fortyfifth days were performed ultrasonographic measurements of the thickness of muscle and adipose Longissimus dorsi, and the thickness of the fat layer at the insertion of the tail. We obtained heart rates (HR) at baseline, during maximal work (HR peak), final HR and HR at 10 and 20 minutes after the end of the exercise. We used a completely randomized design with repeated measures and significance level was 10 %. In relation to body weight or measure ultrasound there was no difference between the groups, but was observed reduction of body condition score, reducing over time (p=0,04) of 10 % for the gamma group when compared with the control group (6.5 %). The total cholesterol concentration was higher (p=0.001) for the gamma group (113.99 mg/dL) than the control group (108.55 mg/dL). Regarding the heart rate (HR) effects were observed over the time baseline HR (p=0.001), final (p=0.003), and at the end of exercise after 10 (p < 0.001) and 20 (p = 0.009) minutes. The HR after 20 minutes also showed interaction time*treatment (p=0.05) , the gamma group had lower average (46.03 bpm) than the control group (46.21bpm) , and over the 180 days the average this variable reduced by 30 % for the gamma compared to control group (7 %). Supplementation with gamma-oryzanol in horses undergoing aerobic exercise can provide a reduction of body condition score, raising the concentration of plasma cholesterol and can improve heart rate recovery after exercise.

Full textResumo: As enfermidades podais do membro torácico são a maior causa das alterações musculoesqueléticas que acometem os equinos. A doença do navicular, osteíte podal e a laminite estão entre as enfermidades de maior incidência em equinos, sendo todas elas citadas como afecções de origem vascular. A fotopletismografia é um método diagnóstico não invasivo que quantifica o tempo de reenchimento venoso baseado na circulação periférica terminal. Objetivou-se estudar a exequibilidade e viabilidade da fotopletismografia podal em equinos, padronizando os valores normais para a espécie. Foram utilizados 10 equinos hígidos, avaliando-se os membros torácicos em diferentes superfícies, sendo dividos em dois grupos: Grupo Borracha (GB) e Grupo Concreto (GC). A fotopletismografia foi realizada com os animais em posição quadrupedal, realizando-se movimentos pendulares para mimetizar movimentos de apoio e elevação do membro, realizando-se cinco movimentos consecutivos e então, imediatamente induzidos ao repouso, obtendo-se então, o tempo de reenchimento venoso (TRV). Não houve diferença significativa entre o membro torácico direito e membro torácico esquerdo nos diferentes grupos (p=0,75). A média do TRV nos equinos do grupo borracha (GB) foi de 12,650 ± 1,694 e no grupo concreto (GC) foi de 12,700 ± 1,387 segundos, não demonstrando diferença significativa entre os diferentes pisos (p=0,98).

Abstract: The thoracic limb disorders are the major cause of the musculoskeletal changes affecting the horses. Navicular disease, foot osteitis and laminitis are among the diseases of higher incidence in equines, all of which are cited as affections of vascular origin. Photoplethysmography is a noninvasive diagnostic method that quantifies venous refill time based on the terminal peripheral circulation. The objective is study the feasibility of foot photoplethysmography in horses, standardizing the normal values for this species. Thoracic limbs were used on different surfaces and divided into two groups: Rubber Group (RG) and Concrete Group (CG). The photoplethysmography was performed with the animals in a quadrupedal position, with pendular movements being performed to mimic support and elevation movements. Five consecutive movements were performed, and then immediately induced at rest, and venous refilling time (VRT). There was no significant difference between the right and left thoracic limbs in the different groups (p=0.75). The mean TRV in the horses of the rubber group (GB) was 12.650 ± 1.694 and the concrete group (CG) it was 12.700 ± 1.387 seconds, showing no significant difference between the different floors (p=0.98). The reference values in horses are different in relation to human patients. It can be concluded that the photoplethysmography of the thoracic limbs in horses can be used as an auxiliary method to evaluate the microcirculation of the foot, the reference value fo...

Devido à característica e ao envolvimento vascular da pododermatite asséptica, a compreensão das ocorrências vasculares dentro do casco passou a ser o foco dos trabalhos científicos. A venografia começou a ser utilizada para este fim. É um método de diagnóstico por imagem minimamente invasivo, prático e essencial para acessar a circulação digital. Auxilia, portanto, médicos veterinários e ferradores na escolha da terapêutica apropriada para a restauração da circulação do digito; possuindo acurado valor prognóstico. No presente trabalho, para o estudo venográfico dos cascos de membros torácicos, foram utilizados 19 equinos com idade média de 9,5 ± 4,4 anos, 12 machos e 07 fêmeas, sendo 11 animais com ausência de sinais clínicos de claudicação e 08 apresentando grau de claudicação de apoio, variando de 1 a 4/5, de acordo com método proposto pela AAEP. O objetivo do trabalho foi avaliar venogramas dos dígitos de animais claudicantes e não claudicantes, a partir da criação de escala semi-quantitativa de preenchimento por contraste radiográfico, nas seguintes regiões: arco terminal, vasos laminares dorsais a falange distal, plexo coronário, vasos circunflexos e bulbo do talão. Os dados obtidos foram submetidos à análise estatística ANOVA, complementados por TUKEY, com nível de significância p < 0,05 para comparação entre todos os grupos (membro torácico esquerdo de animais não claudicantes, membro torácico direito de animais não claudicantes, membro torácico esquerdo de animais claudicantes e membro torácico direito de animais claudicantes). Obteve-se diferença estatística entre os venogramas dos animais claudicantes e não claudicantes, não importando o membro torácico utilizado para a análise. Isso significa dizer que o animal com deficiência de apoio apresenta menor perfusão do dígito. Quanto as regiões observadas, a diminuição de irrigação se fez presente com maior frequência no arco terminal, nos vasos circunflexos e nos vasos laminares dorsais.
Due to the characteristic and vascular involvement of aseptic pododermatitis, the understanding of vascular occurrences within the foot became the focus of scientific work. The venography began to be used for this purpose. It is a minimally invasive, practical and essential diagnostic imaging method to access the digital circulation. It assists, therefore, veterinarians and farriers in the choice of the appropriate therapy for the restoration of the circulation of the digit, having an accurate prognostic value. In the present research, 19 horses with a mean age of 9.5 ± 4.4 years,12 males and 07 females, were used for the venography study of the foot of the forelimbs, of wich 11 without clinical signs of lameness and 08 presented a degree of claudication of support, varying from 1 to 4/5, according to the method proposed by the AAEP.The purpose of this study was to evaluate the venograms of the digits of both, claudicating and nonclaudicating animals, from the creation of a semi-quantitative scale flilled by radiographic contrast data, of the following regions: terminal arch, dorsal laminar vessels to the distal phalanx, coronary plexus, circumflex vessels and heel perfusion. The gathered data were submitted to ANOVA statistical analysis, complemented by TUKEY, with significance level p <0.05 for comparison between all groups (left thoracic limb of non-claudicating animals, right thoracic limb of non-claudicating animals, left thoracic limb of claudicating animals and right thoracic limb of claudicating animals). There was a statistical difference among the venograms of the claudicating and non-claudicating animals, regardless of the thoracic limb used for the analysis. This means that the animal with a support deficiency has lower perfusion of the digit. Regarding the regions observed, the decrease of irrigation was more frequently present in the terminal arch, circumflex vessels and dorsal laminar vessels.

Full textRESUMO: Objetivou-se avaliar o efeito da suplementação de levedura Saccharomyces cerevisiae na dieta de equinos senescentes e seus efeitos sobre o desempenho e coeficientes de digestibilidade aparente de nutrientes. Foram utilizados 18 equinos machos castrados, sem raça definida, com peso médio 426,167±25,3kg e idade média de 17,5±1,42 anos. Os tratamentos consistiram na utilização de diferentes fontes de leveduras adicionados a 200g de concentrado, sendo: tratamento controle - sem adição de levedura (10mL meio de cultura estéril); tratamento contendo a levedura Saccharomyces cerevisiae, UFMG 905 na concentração de 3x108 UFC/mL/dia; e o tratamento contendo probiótico comercial composto por Lactobacillus casei >7,9x104UFC/mL, Lactobacillus acidophilus >7,9x104UFC/mL e Saccharomyces cerevisiae >1,5x106UFC/mL. A dieta padrão foi composta por concentrado comercial e feno Tifton 85 (Cynodon spp) na proporção de 30:70, respectivamente. O experimento teve a duração de 31 dias, sendo 28 dias de adaptação e três dias para o ensaio de digestibilidade. Foi avaliado o desempenho dos animais por meio do peso, consumo de concentrado, de volumoso e da dieta total. Para determinação dos coeficientes de digestibilidade foi utilizado o método de coleta total de fezes. O isolamento de microrganismos Lactobacillus spp. usou-se a contagem direta em placas. O delineamento foi inteiramente casualizado, sendo três tratamentos e seis repetições, considerando o animal a unidade experimental. Os dados foram analisados por meio da ANOVA e teste Dunnet, considerando 5% de significância para as variáveis de desempenho e 10% para os coeficientes de digestibilidade. O peso final, consumo de concentrado, volumoso e dieta total não diferiram entre os tratamentos (P>0,05). Entretanto, houve aumento do peso (P=0,03) e maior ganho de peso (P=0,03) nos animais suplementados com a levedura UFMG 905. A matéria orgânica, extrato etéreo, fibra em detergente neutro, fibra em detergente ácido e teor de carboidratos não estruturais não diferiram entre os tratamentos (P>0,10). Entretanto, os coeficientes de digestibilidade da matéria seca (P=0,05) e da proteína bruta (P=0,10) foram maiores no tratamento comercial em relação ao controle e o coeficiente de digestibilidade da hemicelulose foi reduzido (P=0,01) no tratamento comercial em relação ao controle, o crescimento bacteriano nos tratamentos UFMG905 e comercial foram semelhantes entre si com elevação de 106 para 107 ufc/g. Em conclusão, a suplementação de probiótico contendo Saccharomyces cerevisiae em dietas para equinos acima de 16 anos, aumentou o ganho de peso, a digestibilidade da matéria seca e da proteína bruta e favoreceu um crescimento de Lactobacillus spp., podendo ser utilizado como probiótico. Mais estudos são necessários no sentido de definir concentrações ótimas de leveduras e seus efeitos em equinos.

Full textEl sistema nervioso tiene como función primordial regular las diversas actividades del organismo. Recibe a cada minuto millones de fragmentos de información procedentes de los distintos nervios y órganos sensitivos para generar múltiples respuestas en el organismo. En animales con desórdenes neurológicos se muestran signos pocos claros y confusos, por lo que se requiere establecer un plan diagnóstico preciso y detallado así como diferencial con otros sistemas orgánicos. El examen neurológico sirve para establecer si un problema neurológico está presente, para determinar la localización anatómica del problema y establecer pronóstico del problema. En caballos con neuropatías se pueden presentar múltiples alteraciones de la conducta, consciencia o de la marcha. Dado que el diagnóstico de enfermedades neurológicas en los caballos podría llegar a ser un reto muy importante para el clínico, el objetivo de este manual es brindar información precisa sobre cómo realizar un examen neurológico de forma práctica y precisa. En este documento se explicaran los pasos del examen neurológico en caballos puntualizando detalles de anatomía, fisiología y alteraciones del sistema nervioso.

Full textThe concentrate to replace part of the forage in the diet, mainly cereal grains rich in starch, in order to meet the energy needs of the animal, may exceed the digestive capacity of the small intestine and reach the cecum and colon, resulting in changes in the microbiota and causing gastrointestinal disorders. The aim of this study was to evaluate the effect of supplementation of carvacrol as essential oil on the apparent digestibility of nutrients, glucose and insulin responses postprandial fecal pH, plasma levels of triglycerides, total cholesterol and its fractions high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) very low density lipoprotein (VLDL-C). Were used eight animals, Mini-horse breed, geldings, aged 42±6 months, average weight 135±15 kg, fed a diet containing high relation concentrate:roughage, consisting of 60% commercial concentrate and 40 % of grass hay, which variation was the inclusion of essential oil containing 7% carvacrol, with the treatments divided according to the level of inclusion: 0 (control), 100, 200 and 300 ppm. The experimental design was 4x4 latin square with repeated measures over time and the data were subjected to analysis of variance with a significance level of 5%. The results of the digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral detergent fiber (NDF) and acid deterge nt fiber (ADF) were, respectively, P=0.48; P=0.66; P=0.58; P=0.64; P=0.55; P=0.58 and P=0.46. Faecal pH values were found suitable (pH=6.38) to the balance of microorganisms, and there was no effect of treatment (P=0.84). In evaluation of the area under the curve (AUC), weren´t observed effects of treatment (P=0.48) values for glucose. The response of plasma insulin showed a quadratic effect for AUC (P=0.05) in times 90, 150 and 210 minutes. In the evaluation of plasma lipids wasn´t found effect treatment of the triglyceride value (P=0.37) for total cholesterol, and HDL-C, LDL-C and VLDL-C values were respectively (P=0.85; P=0.57; P=0.94 and P=0.37). The inclusion of essential oil in the diet does not promote effect on digestibility, glycemic response, plasma levels lipids and plasma pH of feces. The inclusion of essential oils promotes effect on the insulin response.

Full textNa espécie equina a placenta é do tipo epiteliocorial, o que impossibilita a passagem de anticorpos para o feto durante a gestação. A transferência de imunidade depende integralmente da ingestão e absorção intestinal das imunoglobulinas (Ig) maternas veiculadas pelo colostro, nas primeiras 24 horas de vida. As infecções neonatais devem-se, principalmente, à falha na transferência passiva de imunidade (FTPI), que tem como principais causas a lactação prematura, a produção de colostro de fraca qualidade ou em reduzida quantidade e a incapacidade de ingestão de colostro ou falha/anomalia na absorção intestinal de Ig. O principal objectivo deste trabalho consistiu na avaliação de factores que influenciam a transferência passiva de imunidade (TPI), através da determinação das concentrações de IgG e Proteína Total (PT) no soro de éguas, no dos respectivos poldros e no colostro (antes e após a sua ingestão). Foi determinada a densidade do colostro com o auxílio de um colostrómetro, a concentração de PT pelo método de Bradford e o teor de IgG por cromatografia por afinidade (High Performance Liquid Chromatography). Paralelamente, no pós-parto foram avaliados os parâmetros vitais do poldro com vista à determinação da sua categoria de risco, tendo-se verificado posteriormente a sua correlação positiva com o seu nível sérico de IgG. Nas amostras de colostro recolhidas após ingestão, e considerando a variável tempo decorrido desde o parto, verificou-se um decréscimo significativo do rácio IgG:PT. Não se verificou a existência de correlação entre o nível sérico de IgG na égua e no respectivo colostro, assim como entre o colostro e os níveis séricos nos poldros em que se verificou prévia ingestão. Contudo, o nível sérico de IgG na égua parece influenciar positivamente o respectivo nível sérico nos poldros que ingeriram colostro. Foram encontrados níveis séricos de IgG mais elevados em poldros que ingeriram colostro relativamente aos que não ingeriram, o que confirma o importante papel do colostro na TPI. Com a realização do presente trabalho, concluiu-se que os níveis de PT no poldro podem ser falíveis para a avaliação da TPI.
ABSTRACT - In the equine species the placenta is epitheliochorial, which does not allow the transfer of antibodies to the fetus during the pregnancy. Therefore, the transfer of immunity from the mare to the foal entirely depends on the ingestion and intestinal absorption of maternal immunoglobulins (Ig) from the colostrum in the first 24 hours of life. The neonatal infections are mainly due to the failure of passive transfer of immunity (FTPI) that has as main causes premature lactation, production of low quality colostrum or in reduced quantity and incapacity to suckle or failure to absorb the Ig. The main aim of this work consisted of the evaluation of factors that influence the transfer of passive immunity (TPI) through the determination of IgG and Total Protein in mares’ serum, their respective foals’ serum and colostrum (pre and post suckling). The determination of the colostrum density by a colostrometer, total protein content with the Bradford Protein Assay and the content of IgG by High Performance Liquid Chromatography were performed. Evaluation of the vital parameters of the foal in the post-partum period was carried out, as well as the determination of their risk category and it has been observed a relationship between the risk category and the IgG level in the foals’ serum. In the colostrum samples collected after suckling and considering the time elapsed since parturition, it was observed a significant decrease of the IgG:PT ratio. A correlation between mare’s serum IgG and colostrum could not be reached, as well as between the colostrum and the foals after suckling. However, mare’s serum IgG seem to positively influence the foals’ serum IgG level in the foals that had suckled. It could be observed an increased serum IgG levels in foals that had suckled comparing with the ones that did not, fact that confirms the important role of colostrum in TPI. With the completion of this work, a conclusion was reached that total protein levels in the foal can be considered an unreliable parameter to evaluate the TPI.

Full textSeminal plasma (SP) proteins have been assessed in relation to reproductive fertility levels or infertility, in several species of mammals, particularly domestic animals. Horse seminal plasma proteins 1 (HSP-1) and 2 (HSP-2) are the most abundant proteins in equine seminal plasma. The aim of this study was to investigate in adult stallions the concentrations of seminal plasma HSP-1/2 and total protein in the breeding season and non-breeding season and to determine if these concentrations were related with fertility. SP was obtained from 42 ejaculates of 11 adult stallions (3-25 yrs). Stallions were allocated into two groups (good and poor fertility) according to pregnancy rates of mares, and to their semen viability data in the first collection day. Seminal plasma HSP- 1/2 concentrations (mg/mL) were measured and analyzed by an Ultra High Performance Liquid Chromatography using a UHPLC column. There were significant differences (P<0.05) in total protein and HSP-1/2 concentration (mg/mL, mean ± SD) in the ejaculates from good and poor fertility stallions. The HSP-1/2 concentration did not show differences in the first and second ejaculates of good fertility stallions in both the non-breeding and breeding season. SP of stallions classified as poor fertility showed significant difference (P<0.05) in HSP-1/2 concentration between the first and second ejaculate in both the non-breeding and breeding season. In conclusion, the concentration of the major proteins of stallion seminal plasma HSP-1/2 was higher in ejaculates from stallions with poor fertility, is not influenced by the season and could serve as biomarker for poor fertility in stallions.

Full textThe equine placenta is diffuse epitheliochorial microcotyledonary type. The initial chorionic macrovilli begins to develop and interdigitate in the endometrium after 40 days of pregnancy. Many studies described aspects of placental development; however, on early stages scanning electron microscopy (SEM) data are scant. The aim of present study was to describe some of the changes occurred in a developmental chorion during gestation. The microcotyledon structure was studied in the period since 62 days of gestation until close to term, by SEM and light microscopy. The samples of chorioallantois were collected from 28 mixed breed mares in a commercial equine abattoir. The estimated gestational ages of each sample were 62, 85, 110, 118, 136, 149, 185, 222, 230, 250 and >300 days. Our results revealed round macrovilli, or the forerunners of microcotyledons, diffusely located and close to one another. They are a shallow cluster like a pile of chorionic protruded cells at 62 days of pregnancy. On the 85th day, the chorionic surface becomes undulated and the microvilli are recognizable. They increased in height and begun to acquire single branch appearance. At 110 days the areole are easily recognized between the pools of villi. These are now higher than earlier, still unbranched and present folding of chorionic surface. The single villi promote primary branching as short rods until 149 days. They are located as tufts gathered together and begin to form the microcotyledon. Many elongated single villi are apposed to multibranched ones from the 185 days; most of them branched in a “Y” shape. The microvillus promote secondary (at 222 days) and tertiary (at 250 days) branching. In addition, histotrophe was identified in many samples throughout gestation and new microvilli were noticed even at latter stages of gestation, suggesting the continuous development of chorionic cells into brand new villus, a clear response to the demand of continues fetus growth.

Full textLa osteoartritis (OA) o enfermedad degenerativa articular del equino de deporte es una de las afecciones más comunes que pueden afectar a estos animales. Se puede generar en diversas articulaciones que incluyen la articulación interfalangica distal, metacarpo-falángica, carpo-metacarpiana, intercarpiana, entre otras. Esta enfermedad no tiene predisposición racial, afectando a caballos que realizan diferentes actividades deportivas tales como rodeo, hípica, equitación, polo, entre otras. Tiene múltiples causas pero la principal es el trauma, pudiendo ser éste de alta o de baja intensidad, se genera a consecuencia de fuerzas normales sobre una articulación anormal, de fuerzas anormales sobre una articulación normal. Cualquiera sea la causa lo que se genera finalmente es la destrucción del cartílago articular y se inicia un proceso degenerativo sobre la articulación. El grado de cojera no se correlaciona necesariamente con el grado de alteración o destrucción de la articulación, encontrándose lesiones radiográficas sin signología clínica, o cojeras evidentes con lesiones radiográficas menores. Lamentablemente una vez iniciado el cuadro no tiene reversibilidad ni tratamiento, por lo tanto, todas las medidas terapéuticas utilizadas tienen por objetivo frenar la progresión del cuadro o al menos disminuirla, si bien existen tratamientos novedosos que buscan la regeneración y reparación de la articulación como es el uso de células madres, plasma rico en plaquetas ( PRP), los resultados son aún inciertos e incompletos, por lo que generalmente se recurre al uso de antiinflamatorios no esteroidales (AINEs), nutraceuticos, ácido hialurónico (HA), glucosaminoglicanos (GAGs), sin embargo, ninguno de estos ha demostrado tener mejor resultado que el uso de corticoides intraarticulares, los cuales siguen siendo el tratamiento de elección para permitir mantener al ejemplar en competencia. Lamentablemente aún no existe un consenso sobre dosis, frecuencia y tipo de corticoides a usar, y la mayoría de los reportes obedecen a experiencias empíricas de su aplicación clínica, por lo anterior y a fin de aprovechar todos los efectos beneficios y minimizar los adversos de estas drogas, se recopiló y actualizó la información existente al respecto, con el fin de integrarla y proponer la forma correcta de aplicarlos en el tratamiento de esta enfermedad.
Osteoarthritis or joint degenerative disease of the sport equine is one of the most common conditions that can affect these animals. It can be generated in various joints that include the distal interphalangeal, metacarpo-phalangeal, carpo-metacarpal, intercarpal articulation among others. This disease has no racial predisposition, affecting horses that perform different sports activities such as rodeo, horse riding, riding, polo, among others. This disease has multiple causes but the main one is the trauma, which may be high or low intensity, being able to be generated as a result of normal forces on an abnormal joint or of abnormal forces on a normal joint. Whatever the cause, what is ultimately generated is the destruction of the articular cartilage and a degenerative process begins on the joint. The degree of lameness does not necessarily correlate with the degree of alteration or destruction of the joint, being able to find radiographic lesions without clinical signology or evident lameness with minor radiographic lesions. Unfortunately, once the condition has begun, there is no reversibility or treatment, therefore all the therapeutic measures used are aimed at slowing the progression of the condition or at least reducing it, although there are new treatments that seek regeneration and repair of the joint, such as use of stem cells, PRP, the results are still uncertain and incomplete, so it is generally resorted to the use of NSAIDs, nutraceuticals, hyaluronic acid, glycosaminoglycans, however, none of these has been shown to have better results than the use of intra-articular corticosteroids , which are still the treatment of choice to allow keeping the specimen in competition. Unfortunately, there is still no consensus on dosage, frequency and type of corticosteroids to be used, and most of the reports are based on empirical experiences of their clinical application, because of the above and in order to take advantage of all the benefits and minimize the adverse effects of these drugs, the existing information was compiled and updated, in order to integrate it and propose the correct way to apply them in the treatment of this disease.

O vírus Vaccina (VACV) é o agente etiológico da vaccínia bovina, doença zoonótica re-emergente e de grande importância socioeconômica. Raros são os relatos de VACV em equinos no Brasil, um dos mais recentes data de 2008 no município de Pelotas- RS, no qual duas cepas, Pelotas Vírus 1 e Pelotas Vírus 2 (P1V e P2V), acometeram 14 animais. Essas cepas foram inoculadas em equinos com o objetivo de verificar se há o desenvolvimento da infecção, assim como de lesões macro e microscópicas. Para tanto, seis equinos adultos e sadios foram inoculados via escarificação do plano nasolabial e foram acompanhados durante 28 dias pós inoculação (d.p.i.). Os animais desenvolveram lesões macroscópicas compatíveis com aquelas causadas pelo vírus Vaccinia no período compreendido entre dois e oito d.p.i.; análises dos fragmentos de tecidos coletados apresentaram acantose, degeneração balonosa de queratinócitos, úlceras e infecção bacteriana secundária. Inclusões eosinofílicas intracitoplasmáticas foram infrequentemente observadas em queratinócitos degenerados ao redor das áreas de necrose. Apenas um animal apresentou excreção viral nos locais de inoculação confirmada via PCR. Os resultados obtidos neste estudo demonstram que a inoculação das cepas P1V e P2V resultam em infecção e no desenvolvimento, ainda que brandas, de lesões macro e microscópicas. Estes achados sugerem que equinos apresentam baixa susceptibilidade ao VACV, especialmente às cepas P1V e P2V, e possivelmente representam baixo potencial transmissor do vírus para outras espécies. Portanto, estudos adicionais são necessários para avaliar o potencial de equinos na disseminação e/ou manutenção destas cepas do vírus Vaccinia em equinos, bovinos e no homem.
Vaccinia virus (VACV) is the etiologic agent of bovine vaccinia, a zoonotic re-emerging disease of high socioeconomic impact. There are few reports of VACV in horses in Brazil. The most recent was described in the city of Pelotas in 2008, where two strains, Pelotas Virus 1 and Pelotas Virus 2 (P1V and P2V), infected 14 animals. These strains were inoculated in horses in order to verify whether experimental inoculation results in infection, and gross and microscopic lesion development. Therefore, 6 adult healthy horses were inoculated via scarification of nasolabial surface. These animals were daily examined for 28 days post inoculation (d.p.i.). Gross lesions consistent with those caused by vaccinia virus were observed between 2 and 8 dpi. Microscopically there were epidermal hyperplasia (acanthosis), ballooning degeneration of the stratum spinosum, necrosis and loss of the epidermis, with intralesional bacteria. Moderate infiltration of neutrophils, macrophages and lymphocytes were observed in the superficial dermis. Intracytoplasmic eosinophilic inclusions were infrequently observed in degenerate keratinocytes from adjacent necrotic areas. Only one animal had viral excretion from the inoculation site, confirmed by PCR. The results of this study demonstrate that the inoculation of P1V and P2V strains result in infection, although mild, with macro and microscopic lesion development. These findings suggest that horses have low susceptibility to VACV, especially to P1V and P2V strains, and possibly represent low potential to transmit the virus to other species, especially dairy cattle. Therefore, additional studies are needed to evaluate the potential of horses in the dissemination and/or maintenance of these strains of vaccinia virus in cattle, horses, and in humans.

Full textGlycerin in food can be considered a good source of energy. Thus, its use as a substitute part of grains and other starchy foods is widely studied since these foods can cause metabolic and digestive changes when in high consumption. The objective of this study was to compare levels of glycerin addition in the equine diet. Eight male, castrated Mini-Horse male ponies, aged approximately 9 years ± 6 months, mean body weight of 149.80 ± 17.20 kg and mean body score of 5.4 ± 0.7 were used. The animals were housed in individual stalls. Individual daily consumption of 1.75% of body weight (CP) was used, with 1% CP in dry matter (DM) from bulky and 0.75% CP in DM from concentrate, with a ratio of 60:40 voluminous: concentrate). The experimental design used was the contemporary 4 x 4 double Latin square. The diets differed in the glycerin inclusion levels (0, 4, 8 and 12%) that were calculated in relation to the percentage of concentrate supplied per animal. The evaluations were performed in four periods, 14 days of adaptation to the diet, 5 days of total collection of feces (TCF) and 2 weeks of interval between periods. The total apparent digestibility of nutrients and fermentability of glycerol from the TCF were evaluated through glycemic, insulinemic, short chain fatty acid, non-esterified fatty acid (NEFA) and faecal pH analyzes. Safety and acceptability analyzes were also performed, which consisted of analyzes of liver and renal function, triglycerides, cholesterol and fractions, besides the evaluation of the animals\' feeding behavior. In addition to analysis of economic implications from the simulation of substitution of corn by crude glycerin. The data were submitted to analysis by the Statistical Analysis System (SAS Institute Inc., 2010). For the significant results, the Tukey test was used with P <0.05. There were no differences between treatments in any of the analyzes performed (P <0.05). Glycerin was palatable and acceptable. The substitution of corn for glycerin, even at 1%, represents economically 0.42% gain. The supplementation of crude glycerin in the equine diet presents itself as safe, without affecting the alimentary behavior, the hygiene and the digestive health of the animals, with economic justification for use.

Full textThis study characterizes Trema micrantha poisoning in horses, previously unknown in this species. The first article (Article 1) describes an outbreak of T. micrantha poisoning in horses. The disease occurred in June 2007, in the Municipality of São José do Herval, Rio Grande do Sul State. Two horses died after consuming the leaves of the branches from a T. micrantha tree, which had been felled by a storm. Clinical pathology presented by the animals was characteristic of an acute liver failure with development of hepatic encephalopathy. To further characterize the Trema micrantha poisoning in horses, an experiment was carried out (Article 2). Four ponies received and spontaneously consumed green leaves of T. micrantha, at the doses of 30, 25, and 20 g/kg. One horse received two doses, 15 and 25 g/kg, 30 days apart. Three animals were affected and died. The main clinical signs were apathy, equilibrium deficit, deglutition difficulty, sternal or lateral recumbency, paddling, coma and death. These tree diseased ponies had also enhanced seric activity of gamma-glutamyl transferase (GGT), seric ammonia apart of diminished glycemia. The main pathological findings were observed in the liver and encephalon. There were enhanced lobular pattern of the livers and yellowish areas in the cut surface of the encephalon, especially visualized in the cerebral white matter. Microscopically, there was hepatic necrosis predominantly centrilobular apart of hemorrhages. Generalized perivascular edema and Alzheimer type II astrocytes were observed in the encephalon. The Alzheimer type II astrocytes showed weak or absent anti-glial fibrillar acid protein immunostaining associated with positive immunostaining for S-100 protein. The minimal lethal dose of Trema micrantha leaves was established at 20 g/kg. The high sensibility of this species to this plant, its wide distribution, and the high palatability of the plant reinforce the importance of Trema micrantha in accidental episodes of intoxication in horses.

Full textThe technique of exploratory laparoscopy abdominal cavity used currently in horses involves a series of difficulties. There is need for bilateral abdominal cavity surgical access or general anesthesia for ventral access for the purpose of obtaining an adequate assessment of the viscera and, consequently, a more accurate diagnosis. This procedure extends and increases the risks of post-surgical complications and transoperatórias. Despite being a well-established technique in situations where the advantages of its use are evident, some factors still limit its spread, some of them are: the cost of equipment that limits the use out of universities, research centers or private clinics specialized in veterinary surgeries. In order to minimize the negative aspects of this technique and enable its use in routine clinical and surgical equine, the idea of seeking a new route to the abdominal cavity and using videocolonoscópio, lower equipment cost. In the present study, we analyzed the use of the flexible endoscope in the abdominal exploration equine barrows and gilts for access perianal. The technique was evaluated on the feasibility of allowing or not the access cavity and identification of the abdominal viscera in horses. In addition, sought to verify that the flexible endoscope allows obtaining liver tissue samples for histological evaluation. The animals were fed, wormed and evaluated daily by a general clinical examination during the period of the experiment. Sampling of blood for blood count and fibrinogen were measured before and after the surgical procedure for subsequent analysis. All routine care in relation to surgical antisepsis were duly taken and animals undergoing sedation and analgesia protocol. Procedures as postoperative analgesic therapy, anti-inflammatory, inspection and cleaning daily incision site were provided. The procedure began with surgical incision in the right laterodorsal perianal region between the anus and the semimembranosus muscle using a scalpel and scissors, then blunt dilatation of the finger along the rectal wall until it reaches an approximate depth of 10 cm, at which the metal cannula with 56 cm length and 16 mm in diameter (Ø) was introduced. Through this cannula was inserted flexible endoscope (videocolonoscópio), the remainder of the introduction of the cannula followed by indirect viewing monitor. The cannula was forced slowly to the peritoneal cavity, the time from which it was held exploration of the abdominal cavity. The cannula was forced slowly to the peritoneal cavity, the time from which it was held exploration of the abdominal cavity. The viscera were observed in annotated form specially developed for this purpose. As part of the evaluation of the liver, biopsy was performed and the obtained material analyzed at the pathology of the Veterinary School of UFRGS. After ten days postoperatively, when in full health, horses were discharged. The results allow us to conclude that the use of the flexible endoscope in the identification of abdominal viscera through perianal laparoscopy is feasible in routine clinical and surgical equine and enables to obtain tissue samples for histologic evaluation. However, the use of the technique requires training of the surgical team, especially the surgeon, good planning and a preoperative diagnosis requiring incomplete diagnostic workup.

Full textO termo “cólica” é referente a um conjunto de manifestações de dor abdominal, geralmente com origem ao nível do tracto gastrointestinal ou, menos frequentemente, em outras estruturas localizadas no interior do abdómen. Embora nem sempre seja possível estabelecer um diagnóstico, as causas mais frequentes parecem ser as obstruções simples. Além disso, os quadros de cólica são muitas vezes moderados, resolvendo-se espontaneamente ou necessitando apenas de uma intervenção terapêutica. No entanto, trata-se de uma das entidades clínicas mais importantes na medicina equina, não só pela sua prevalência como também pelas suas consequências. De facto, e apesar dos meios de diagnóstico e tratamento actualmente disponíveis, a cólica pode acarretar prejuízos económicos avultados para os proprietários, para além do respectivo envolvimento afectivo. Assim, é importante que o prognóstico seja o mais exacto possível, uma vez que é fundamental para a tomada de decisões sobre a gestão de cada caso clínico. Nesse sentido, têm vindo a ser realizados numerosos trabalhos com o intuito de utilizar as informações recolhidas durante o exame clínico para melhorar a capacidade de o médico veterinário estabelecer um prognóstico. De entre todos os parâmetros que têm sido estudados, os que mais frequentemente apresentam uma associação com o desfecho dos casos de cólica são aqueles que reflectem a condição cardiovascular. O presente trabalho teve como principal objectivo apresentar os factores de prognóstico da cólica em equinos que têm vindo a ser referidos na literatura, bem como estudar a importância de alguns deles numa amostra da população compreendendo 20 casos de cólica com origem ao nível do tracto gastrointestinal (incluindo a peritonite). Através da análise dos resultados obtidos, foi possível constatar que, comparativamente com os cavalos sobreviventes, aqueles que morreram apresentaram um grau de dor e um tempo de repleção capilar mais elevados, uma coloração anormal das mucosas e uma motilidade intestinal mais reduzida. Além disso, verificou-se que a temperatura rectal, a frequência cardíaca e a concentração sanguínea de glucose elevadas, bem como a presença de uma baixa concentração plasmática de proteínas totais, estavam associadas a um prognóstico desfavorável. Embora não tenham sido encontradas diferenças significativas entre os grupos de desfecho no que respeita à concentração sanguínea de lactato, os resultados obtidos revelaram uma grande proximidade em relação ao nível de significância considerado, tendo-se registado valores superiores para este parâmetro no grupo dos não sobreviventes.
ABSTRACT - Prognostic factors in equine colic - The word “colic” often refers to a particular set of manifestations of abdominal pain that are frequently related with the gastrointestinal tract or, to a lesser extent, with other structures located in the abdomen. The more frequent causes seem to be related with simple obstructions, although it is not always possible to establish a diagnosis. Also, the clinical boards associated with colic often present themselves as moderate and tend to self-resolve or need simple therapeutic intervention. Nevertheless, this is one of the most important clinical subjects in equine practice not only due to its wide spread occurrence, but also because of its consequences. In fact, and despite all the diagnosis techniques currently available and the continuous evolution in treatment, colic related problems tend to result in large expenses for the owners, as well as affective issues concerning personal loss. It is therefore important that the prognosis is as accurate as possible since it plays a key role in all the decisions that need to be taken and in the management of each clinical case. Numerous research efforts have thus been undertaken with the goal of using the information gathered during the clinical examination to improve the veterinarian’s ability to establish a prognosis. Of all the parameters that have been studied, those that are more often associated with the outcome are the ones that reflect the patient’s cardiovascular status. The present study sets its main goal in presenting the colic prognostic factors referred to in the literature, and to study the importance of some of them in a sample of 20 horses with colic of gastrointestinal origin (also including peritonitis). The analysis of the results enabled to conclude that in comparison with the survivors, the non survivors presented higher severity of pain and capillary refill time, abnormal mucous membranes colour, and reduced intestinal motility. Also, higher rectal temperatures, heart rates and blood glucose concentrations, and lower plasma total protein concentrations, were found to be associated with worse prognosis. Although no significant differences have been found within the two outcome groups for the blood lactate concentration, the results revealed only a slight difference to the considered significance level, and higher values of this parameter were found for the non survivors.

Full textThe objectives of this study were to characterize age-associated changes in testicular size and blood concentrations of testosterone, as well as evaluate the presence of epididymal sperm. The testicular maturity was evaluated by measuring seminiferous tubule diameter and the presence of the most advanced germ cells in the seminiferous epithelium of colts in the peri–puberty period. The animals were surgically castrated and thorax circumference was taken to estimate the body weight. Thirty four male horses were grouped into four categories: Group I (GI) with four foals aged up to 14 months; Group II (GII) with seven animals over 14 months and less than 17 months; The third group (GIII) included 14 animals over 17 months and less than 19 months; Group (GIV) was composed of nine horses over 19 months and under 34 months of age. After castration the testes were weighed and measured. A segment was collected for subsequent histological evaluation, including measurement of the diameter of the seminiferous tubules and the presence of germ cells of the seminiferous epithelium at different stages of development. A blood sample was collected for determination of plasma testosterone. The average body weight of the animals increased significantly from 232 kg in GI to 321 kg for horses in GIV. There was no difference between measures taken on right and left testes. The testicular weight and volume was greater in animals of GIV and differed significantly compared to the younger animals. Plasma levels of testosterone did not differ between age groups. The diameter of the seminiferous tubules increased from 89.13 μm in foals of GI to 168.24 μm in horses of GIV. On average, 17.5% of the seminiferous tubules had no germ cells in animals of GI, decreasing to 5.4% in GII, 5.2% in GIII and 0.8% in GIV. The number of tubules containing mature spermatids and spermatozoa increased with age. Most significant variations in the increase of testicular volume and diameter of seminiferous tubules were associated with a high presence of spermatozoa in the tubules. In conclusion all animals with 20 months of age or more had reached puberty in the present study and the first spermatozoa appeared in 16 month old colts. All animals presented epididymal sperm when testicular volume and weight were over 16cm3 and 23g, respectively.
