Regenerative medicine for tendinous and ligamentous injuries of sport horses. After tendon injury, the scar tissue that replaces the damaged tendon results in a substantial risk for reinjury. The goal of regenerative therapies is to restore normal structural architecture and biomechanical function to an injured tissue. Successful restoration processes for any tissue are thought to recapitulate those of development, in which there are spatial and temporal interactions between scaffold, growth factors, and cell populations.
The California Postmortem Program: leading the way. The California Postmortem Program studies disease surveillance, discovers new causes of death, and develops new diagnostic methods for disease detection. It also informs directions for research focused on elucidating the etiopathogenesis of, and risk factors for, catastrophic fractures and other causes of death. Because most fatal injuries seem to be the acute culmination of a more chronic process, intervention and prevention of injuries is possible with enhanced knowledge of the etiopathogenesis of injuries and risk factors for injuries. These advances also would facilitate development of man...
Epidemiology of racetrack injuries in racehorses. This article describes the development of epidemiologic analyses of racetrack injury in racehorses. The risk or rate of fatal and nonfatal injury in racing and training around the world is examined. The focus is on the importance of global collaboration and the identification of modifiable risk factors. In particular, exercise-related risk factors for injury are evaluated and the potential impact of interventions discussed.
Future tools for early diagnosis and monitoring of musculoskeletal injury: biomarkers and CT. This article provides an overview of two relatively new techniques that can be used for the early detection of musculoskeletal injury: biochemical markers and CT. The emphasis in the biomarker section is on the early detection of joint disorders because these are most important clinically and most of the research has been conducted in this area. In the section on CT, bone is the target tissue.
Biomechanical and mechanical investigations of the hoof-track interface in racing horses. The aim of this article is to review current knowledge of kinetic variables of the hoof-track interaction and track properties relevant to the objective of minimizing injuries to horses at racing tracks. In each phase of the stance--primary impact, secondary impact, support, and breakover, the hoof experiences different combinations of force and acceleration. The role of each combination, and of measured track properties, in causing catastrophic and chronic injuries to the limbs of racing horses is unknown. Limited data of this type have been provided in previous epidemiologic studies of risk ...
Musculoskeletal injuries in nonracing quarter horses. Quarter horses used for western performance competitions commonly sustain a variety of musculoskeletal injuries. It is important for the veterinarian to have an understanding of some of the breed characteristics and the nature of the competitions in which individual horses are being used so as to diagnose, treat, and prevent injury as effectively as possible.
Adaptation strategies of horses with lameness. The skill to diagnose lameness in horses is paramount for every equine practitioner. Early recognition of locomotor deficiencies plays a central role in sports medicine management, preventing deterioration of the disease or catastrophic injuries. Horses use characteristic compensatory movements of specific body parts to decrease loading of the affected limb. This article describes the underlying changes in intra- and interlimb coordination and the resulting load redistribution between the limbs. This enables the practitioner to better understand the changes in movement associated with lameness...
Congenital anomalies of the equine urinary tract. Congenital anomalies of the urinary tract in horses may be difficult to diagnose and treat. Presenting complaints are variable and include weight loss, depression, dysuria, hematuria, and mild colic. Although the most severe abnormalities are diagnosed in the neonate, some diseases, such as ectopic ureter(s), may be identified in older horses. In human medicine, the fetus is examined in the prenatal period for evidence of urinary tract dysfunction, but this is not yet common practice in equine medicine. As a result, urinary tract anomalies are diagnosed after birth using a wide variety of diag...
Examination of the urinary tract in the horse. Pathologic conditions of the urinary tract may produce specific clinical signs, but they are more than likely to be nonspecific clinical signs, which often occur with chronic renal disease in addition to countless other diseases. Further, clinical signs that may seem to be directly related to the urinary tract may be the result of other systemic diseases. Thus, before embarking on diagnostics, it is important to obtain a thorough history and physical examination.
Equine renal tubular disorders. Renal tubular disorders have been sporadically reported in horses. Only three types of tubular defects have been recognized: (1) nephrogenic diabetes insipidus, attributable to unresponsiveness of the renal tubules to antidiuretic hormone; (2) distal renal tubular acidosis (RTA; type I); and (3) proximal RTA (type II). The following review focuses on RTA and nephrogenic diabetes insipidus.
Polyuria and polydipsia in horses. Polyuria and polydipsia provide a diagnostic challenge for the equine clinician. This article describes the various known causes of polyuria and polydipsia in horses and provides a description of a systematic diagnostic approach for assessing horses with polyuria and polydipsia to delineate the underlying cause. Treatment and management strategies for addressing polyuria and polydipsia in horses are also described.
Toxins affecting the urinary system. Many different substances can induce toxic damage to various structural components of the equine kidney, and most lack pathognomonic signs. Some of these agents have specific treatments, although many do not. Supportive and symptomatic therapy is an important aspect of treatment of most cases of equine nephrotoxicosis. Regardless of cause, if the toxic substance is removed or neutralized before significant renal damage, full recovery of renal function may occur. Many horses already have significant renal damage before a definitive diagnosis is made, and the prognosis for full recovery thus rem...
Chronic renal failure in horses. Chronic renal failure is a syndrome of progressive loss of renal function that results in loss of urinary concentrating ability, retention of nitrogenous and other metabolic end products, alterations in electrolyte and acid-base status, and dysfunction of several hormone systems. This article describes the prevalence, causes, clinical signs, diagnostic evaluation, and management of horses afflicted with chronic renal failure. It is hoped that this article illustrates that chronic renal failure, when detected in the earlier stages of disease, can be managed successfully in the short-term allowi...
Essentials of equine renal and urinary tract physiology. Knowledge of urinary tract anatomy and the numerous functions of the kidney in regulating fluids, electrolytes, acid-base balance, and waste products improves the ability of the clinician to diagnose, treat, and make appropriate recommendations for the management of the horse with renal disease. Several conditions can directly or indirectly affect renal function on a temporary or permanent basis. Endogenous and exogenous compounds (eg, drugs, toxins, hemoglobin) alone or in combination with inappropriate renal blood flow can promote or exacerbate renal disease.
Equine urolithiasis. The prevalence of equine urolithiasis has been estimated to be low. In horses with clinical signs of urolithiasis, uroliths are most commonly encountered in the urinary bladder, but it is not uncommon to detect uroliths in more than one location. The most common clinical signs for cystic calculi are urine scalding of the hind limbs, hematuria, tenesmus and dysuria. Numerous surgical techniques and approaches have been described for the treatment of urolithiasis in horses; however, independent of which approach is chosen, the goal should be to remove all calculi completely from the urinary trac...
Hematuria and pigmenturia of horses. Hematuria and pigmenturia of horses are discussed in this article. Equine urine is normally straw colored. Discolored urine can be caused by contamination with red blood cells, hemoglobin, myoglobin, oxidizing agents normally found in urine, and plant-derived pigments.
Acute renal failure in horses. Acute renal failure (ARF) in horses is usually prerenal or renal in origin and is most often caused by hemodynamic or nephrotoxic insults. The clinical management of patients that have ARF is largely supportive, including correction of fluid deficits and electrolyte and acid-base disturbances and treatment and reversal of the underlying cause. Use of dopamine and mannitol to promote renal blood flow and urine output is no longer recommended.
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 nutrition. One of the most difficult problems in equine nutrition research is often the lack of objective and clinically relevant end points. Nevertheless, this article attempts to present the best evidence (or lack thereof) for some of the most common clinical questions pertaining to such topics as the evaluation of glucose and insulin tolerance and factors that may confound results, dietary management of horses prone to laminitis and rhabdomyolysis, nutritional prevention of gastric ulcers and developmental orthopedic disease, the efficacy of commonly used herbal products, and feeding geriatric horses....
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 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 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 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...
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...
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 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.
An evidence-based approach to clinical questions in the practice of equine neurology. The practice of equine neurology has special challenges posed by the size of the animal being examined. Many diagnostic procedures routinely used in small animal practice are unsafe when applied to the equine patient or unavailable to the equine practitioner. Therefore, astute observation is the mainstay of making a neuroanatomic diagnosis, and detailed evidence on the deficits present may be difficult to obtain. Because clinical observation can sometimes be ambiguous and somewhat subjective, it is even more important to approach equine neurology from an evidence-based point of view. Here, suc...
