Topic:Veterinary Care
Veterinary care in horses encompasses the medical and preventive measures taken to maintain and improve the health and well-being of equine patients. It includes a wide range of practices such as routine health examinations, vaccinations, dental care, parasite control, and management of injuries and diseases. Veterinary care also involves diagnostic procedures, surgical interventions, and therapeutic treatments tailored to the specific needs of horses. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Estimation of heritability and genetic correlation for behavioural responses by Gibbs sampling in the Thoroughbred racehorse. Genetic variation of the behaviour of racehorses is one of the major concerns for racehorse breeders. In this study, the heritabilities of behavioural responses to the inspections of conjunctiva, auscultation and blood sampling and the genetic correlations among them were estimated in the Thoroughbred racehorse. The estimation was done with Bayesian analysis with Gibbs sampling based on the univariate or bivariate threshold animal models. The behavioural responses were scored with four categories at the first entrance quarantine in Miho Training Center of Japan Racing Association from 1993 to ...
A scientific background for skeletal muscle conditioning in equine practice. The main goal of any conditioning programme in athletic horses is to improve performance by inducing physiological changes within the animal's body. Equine skeletal muscles have a considerable potential to adapt during training and these adaptations have important physiological implications that influence stamina, strength and speed. Although there is an extensive specialized literature in this regard, scientific based muscle conditioning methods have not been introduced sufficiently in the equine sport practice. After a brief synopsis of both equine muscle exercise physiology and muscular ada...
Failure of low-dose recombinant human IL-2 to support the survival of virus-specific CTL clones infused into severe combined immunodeficient foals: lack of correlation between in vitro activity and in vivo efficacy. Although CTL are important for control of lentiviruses, including equine infectious anemia virus (EIAV), it is not known if CTL can limit lentiviral replication in the absence of CD4 help and neutralizing antibody. Adoptive transfer of EIAV-specific CTL clones into severe combined immunodeficient (SCID) foals could resolve this issue, but it is not known whether exogenous IL-2 administration is sufficient to support the engraftment and proliferation of CTL clones infused into immunodeficient horses. To address this question we adoptively transferred EIAV Rev-specific CTL clones into four EIAV-...
Traumatic brain injury in horses: 34 cases (1994-2004). To investigate the clinical, clinicopathologic, and diagnostic characteristics; treatment; and outcome associated with acute traumatic brain injury (TBI) in horses and assess risk factors for nonsurvival in TBI-affected horses. Methods: Retrospective case series. Methods: 34 horses with TBI. Procedures-Medical records of horses that had sustained trauma to the head and developed neurologic signs were reviewed. Data that included signalment, clinicopathologic findings, diagnosis, treatment, and outcome were analyzed. Clinicopathologic variables among horses in survivor and nonsurvivor groups we...
Influence of age and foaling on plasma protein electrophoresis and serum amyloid A and their possible role as markers of equine neonatal septicaemia. A field study was undertaken to investigate plasma protein electrophoresis (PPE) and serum amyloid A (SAA) concentrations at 1, 3 and 7 days of age in foals born by oxytocin-induced (group A, n =17) or spontaneous (group B, n =12) parturition. The putative diagnostic role of PPE and SAA in four septicaemic foals was also examined. At birth, beta-gamma-globulins were higher in group B, and then increased in both groups, probably due to colostrum intake. At day 3, no significant differences between the groups were detectable. In both groups, SAA values increased from day 0 to day 3, then decreas...
Validation of computerized Swedish horse insurance data against veterinary clinical records. The aim was to evaluate the agreement between computerized insurance data in a large Swedish horse insurance database and the information in the corresponding clinical records (CR). A random sample of 400 veterinary care and 140 life claims was included. Information on name of the horse, breed and gender, year of birth, specific diagnosis and system diagnosis (e.g. joints, digestive and skeletal) was compared between sources. The concordance for demographic variables was categorized as agreement, disagreement or data missing. For diagnostic information, the categories were agreement, minor dis...
Clinical and clinicopathologic variables in adult horses receiving blood transfusions: 31 cases (1999-2005). To determine clinical and clinicopathologic abnormalities in horses administered a blood transfusion and evaluate effects of blood transfusion on these variables. Methods: Retrospective case series. Methods: 31 adult horses that received > or = 1 blood transfusion. Procedures-Medical records of horses receiving a blood transfusion were reviewed to obtain clinical findings, laboratory test results before and after transfusion, adjunctive treatments, transfusion type and volume, response to transfusion, results of donor-recipient compatibility testing, adverse reactions, and outcome. Results:...
Radiographic closure time of appendicular growth plates in the Icelandic horse. The Icelandic horse is a pristine breed of horse which has a pure gene pool established more than a thousand years ago, and is approximately the same size as living and extinct wild breeds of horses. This study was performed to compare the length of the skeletal growth period of the "primitive" Icelandic horse relative to that reported for large horse breeds developed over the recent centuries. This information would provide practical guidance to owners and veterinarians as to when the skeleton is mature enough to commence training, and would be potentially interesting to those scientists inve...
Comparison of three dorsal techniques for arthrocentesis of the distal interphalangeal joint in horses. To compare 3 dorsal techniques for arthrocentesis of the distal interphalangeal joint in horses with regard to ease of performing the technique and to determine the role of operator experience in ease of performing these techniques. Methods: Observational study. Sample Population-Forelimbs from 17 equine cadavers and 12 horses (16 joints) undergoing arthrocentesis for therapeutic or diagnostic purposes. Methods: In both forelimbs from 7 of the equine cadavers, 3 arthrocentesis techniques (dorsal perpendicular, dorsolateral, and dorsal inclined) were performed in random order by a single experi...
Volume effects on fatigue life of equine cortical bone. Materials, including bone, often fail due to loading in the presence of critical flaws. The relative amount, location, and interaction of these flaws within a stressed volume of material play a role in determining the failure properties of the structure. As materials are generally imperfect, larger volumes of material have higher probabilities of containing a flaw of critical size than do smaller volumes. Thus, larger volumes tend to fail at fewer cycles compared with smaller volumes when fatigue loaded to similar stress levels. A material is said to exhibit a volume effect if its failure prop...
[Role of IgE-dependent reactions in atopic dermatitis]. Atopic dermatitis is a disease of multifactorial pathogenesis. Objective: of the study was to establish the most common allergens responsible for development of atopic symptoms in children with atopic dermatitis. Methods: the study complied 36 children aged 4 months - 3 years treated in the Department of Children Allergology, Gastroenterology and Nutrition because of atopic dermatitis. With each case the patient and family history of atopy was collected and basic laboratory tests were conducted (including total IgE and specific IgE using Polly Check system). Results: eosinophilia was found in ...
Evidence-based immunization in horses. Evidence of vaccine efficacy is essential for practitioners when giving advice to clients about the relative merits of different vaccines or when trying to evaluate the economic benefits of instituting a vaccine program. In equine veterinary medicine, this sort of data, which are necessary to make informed decisions about vaccine use and effectiveness, are often not available. Veterinarians need to consider the epidemiology of the disease in question, the type of vaccine that they are administering to the animal, the immunologic constraints of the vaccine technology, and the available evidence...
Evidence-based equine dentistry: preventive medicine. Dental problems are some of the most common reasons for a horse to be presented to an equine veterinarian. Despite the importance of anecdotal evidence as a starting point, the science of equine dentistry (especially prophylactic dentistry) has remained poorly supported by evidence-based approaches to diagnosis and treatment. In the 21st century, veterinarians have an ethical responsibility to promote and use the results of evidence-based research and not propagate statements attesting to the purported benefits of intervention without supporting research. Consider also that society is becoming...
Evidence-based medicine in equine critical care. One of the fundamental skills required for practicing evidence-based medicine is the development of a well-built clinical question, which specifies the patient group or problem, intervention, and outcome of interest. For this purpose, various "levels of evidence" have been developed in the human literature, which rank the validity of evidence. Our established conclusions and advice are thus supported by specific "grades of recommendations," which are intended to give an indication of the "strength" of a clinical recommendation. This article was compiled with these principles in mind.
Evidence-based literature pertaining to thyroid dysfunction and Cushing’s syndrome in the horse. The evidence-based literature pertaining to thyroid dysfunction and Cushing's syndrome is discussed in this article. Summaries of and recommendations for the treatment of these conditions are made. There is a need for reliable diagnostic tests for these conditions in horses.
Evidence-based drug use in equine medicine and surgery. The nature of the equine industry and equine veterinary medicine often requires veterinarians to prescribe drugs with little evidence for a drug's formulation safety or efficacy, or even assurance of the chemistry of the drug used. This means that equine veterinarians must remain skeptics and understand the limitations in their ability to attribute safety and efficacy to a particular drug or treatment. An evidence-based approach to pharmacology demands rigorous testing and an unbiased analysis of results.
Evidence-based musculoskeletal surgery in horses. Musculoskeletal disorders comprise a large portion of the conditions treated by equine veterinarians. Surgical intervention is the treatment of choice in many cases. The body of literature describing and exploring surgical correction of musculoskeletal disorders in horses is steadily growing but still lacking. At this juncture, we can use what information we have with the understanding that as the quality of research advances, we should apply stricter standards to the evidence we use to answer our clinical questions.
An evidence-based assessment of the biomechanical effects of the common shoeing and farriery techniques. The first aim of this article is to review the progress made in the field of distal limb biomechanics. By understanding limb biomechanics, it is then possible to review the rationale behind a few of the more common techniques that veterinarians routinely use when treating their patients and to evaluate the evidence in support of them.
An evidence-based approach to selected joint therapies in horses. There is an enormous volume of published material about most of the agents used to treat or prevent arthritis in horses. Unfortunately, most of the claims made by nearly all purveyors of arthritis medications in such media are largely unsubstantiated. In addition, the quality of the available information is highly inconsistent, making evidence-based recommendations difficult. This article concentrates on injectable polysulfated glycosaminoglycan, injectable hyaluronan, and the common oral "nutraceuticals".
Evidence-based gastrointestinal medicine in horses: it’s not about your gut instincts. The use of an evidence-based approach allows veterinary clinicians to assess questions that are clinically relevant to the diagnosis and treatment of equine gastrointestinal tract disease. This approach involves formulating a clinical question, searching the literature, and answering the question with the best available evidence, with the results summarized as a clinical "bottom line." This article is organized to reinforce the principle that the cornerstone of evidence-based medicine is the clinical question. Specific questions are further categorized as to topic, with epidemiologic risk fact...
Common procedures in broodmare practice: what is the evidence? Many procedures performed as part of routine broodmare practice are based on sound clinical judgment and experience or scientific evidence; however, others are based on perceived problems and needs to address them. This article presents four procedures commonly used in broodmare practice, for which there is questionable evidence to substantiate their use.
Fatal brodifacoum poisoning in a pony. Fatal brodifacoum poisoning in a pony is described; this condition has not previously been reported in ponies. Discussion of what factors in the pony's history and treatment may have predisposed to the severity and ultimate death is provided. Cet article décrit un empoisonnement mortel au brodifacoum chez un poney, condition jamais rapportée auparavant. La discussion porte sur les liens entre les divers éléments de l’anamnèse et les traitements reçus par rapport à la sévérité de la condition et ultimement à la mort de l’animal. (Traduit par Docteur André Blouin)
Evidence-based parasitology in horses. This article focuses on what has been established concerning the interaction of equine parasites and their hosts, highlighting those issues for which convincing data are still lacking. There is a compelling need for the participation of the veterinarian in the design of appropriate anthelmintic treatments and prevention strategies.
Evidence-based gastrointestinal surgery in horses. Colic surgery is now performed at many equine hospitals around the world. Despite the tremendous improvements in survival rates over the past 30 years, the morbidity and mortality rates remain relatively high. This fact, coupled with the high cost of treatment, makes it important to apply evidence-based medicine principles to establish the best possible treatment plans and surgical techniques whereby the outcomes can be optimized. Factors affecting survival rates and rates of major complications (incisional complications and postoperative ileus) are discussed. Preoperative assessment and posto...
Myocardial fibrosis in a horse with polymorphic ventricular tachycardia observed during general anesthesia. Ventricular dysrhythmias are more commonly associated with myocardial disease than are supraventricular dysrhythmias. Management of arrhythmias under general anesthesia is difficult because of the dysrhythmogenic effects of the anesthetic drugs. This report describes a severe ventricular dysrhythmia observed in a pony under general anesthesia, with a severe and old myocardial fibrosis found on postmortem examination. Fibrose du myocarde chez un cheval présentant de la tachycardie ventriculaire polymorphe observée au cours d’une anesthésie générale. Les dysrythmies ventriculaires sont pl...
Evidence-based equine upper respiratory surgery. The purpose of this article is to review the veterinary literature for various surgical procedures of the equine upper respiratory tract in an effort to evaluate the evidence supporting various therapies. This article focuses on the therapeutic benefit from more widely occurring conditions, such as laryngeal hemiplegia, dorsal displacement of the soft palate, arytenoid chondritis, and epiglottic entrapment.
Evidence-based respiratory medicine in horses. It is clear from a review of the current scientific literature that an evidence-based approach to medical treatment of equine respiratory disease can be applied, at least in the instance of common lower respiratory diseases. In particular, there is clear evidence for efficacious treatments for recurrent airway obstruction and exercise-induced pulmonary hemorrhage, and with the recognition of this evidence, these treatments should be the first to be considered by a practitioner when treating these conditions. The purpose of this article is not only to identify the existence of relevant high-qua...
