Treatment and prevention of equine gastric ulcer syndrome. EGUS is a common problem in horses and foals. Acids are the important causative factors and current therapy targets the suppression of gastric HCl and creation of a permissive environment for ulcer healing. Diagnosis is based on history, clinical signs, gastroscopy, and response to treatment. Of the products available, only GastroGard (FDA approved) and ranitidine have been shown to be efficacious in the treatment of EGUS. Ranitidine is often associated with treatment failure as a result of incorrect dosing and lack of owner compliance, because of the three times daily dosing required. Also, E...
Treatment of acute and chronic gastrointestinal inflammation. Treating inflammation in the equine gastrointestinal tract remains a challenge. Our most potent anti-inflammatory drugs, COX inhibitors and glucocorticoids, have unwanted effects on the gastrointestinal tract and host defense that often limit their use. Newer strategies targeting specific cells and molecules that regulate a subset of the events occurring during inflammation are rapidly becoming available and should allow clinicians to reduce the detrimental effects of inflammation without inhibiting the beneficial aspects.
Fluid therapy in horses with gastrointestinal disease. Fluid therapy is essential to the successful management of horses with gastrointestinal disease. Affected horses can present in a wide spectrum of metabolic derangement depending on the extent and severity of the underlying disease process. Precise quantitation of fluid deficits and losses is usually not possible; thus, formulating a rational plan, applying diligent and ongoing monitoring, and making adjustments to meet individual demands provide the best approach to fluid therapy in these horses. Although restoration of fluid and electrolyte homeostasis can be complicated, it is probably best...
Treatment of endotoxemia. Although recognition of clinical signs of endotoxemia is not difficult, determining the underlying cause for the development of endotoxemia may be a challenging task. For this reason, importance must be placed on performance of a thorough physical examination, attention to detail, and determination of whether or not surgical intervention is required. In most instances, a definitive diagnosis may require repeated examinations and laboratory work. In the meantime, affected animals require treatment for endotoxemia, with the aim being to reduce the duration of endotoxemia, prevent the interaction...
Gastrointestinal protectants and cathartics. The purpose of this article is to provide the reader with an overview of gastrointestinal cathartics and protectants and to point out possible applications for use in the horse with gastrointestinal disease. Most of the treatments described in this article have been used by the authors with apparent success; however, controlled studies with subsequent publication in the scientific literature with respect to these treatments in the horse are, for the most part, lacking. The authors view this emerging field of treatment as exciting and look forward to substantiating the efficacy of several of th...
Hoof wall surgery in the horse: approaches to and underlying disorders. Because of the hoof capsule, surgery of the equine foot is often perceived to be quite difficult. Knowledge of the specific disease entities that require surgical intervention as well as an in-depth understanding of the anatomy of the tissues beneath the hoof capsule is a definite prerequisite to successful surgical treatment. This article details the surgical approaches used to treat septic navicular bursitis, septic pedal osteitis, infection of the collateral cartilages, and keratomas. The principles used to treat these conditions can be applied to a variety of other conditions for which acc...
Radiographic imaging of the equine foot. Radiographic examination of the equine foot can provide the veterinarian and farrier with a wealth of information. Positioning and selection of exposure factors are of central importance if one is to produce radiographs of maximum diagnostic value.
Proper physiologic horseshoeing. Adherence to the basic principles of physiologic horseshoeing is essential to maintaining hoof health and soundness. Most horses do not require special trimming or shoeing techniques. Becoming familiar with a few basic concepts can help the veterinarian to recognize when changes in trimming or shoeing might be expected to help the performance of a sound horse or might help to restore the performance of one that is lame. Sound physiologic horseshoeing can only be achieved by a thorough knowledge of, strict adherence to, and skillful application of basic principles, such as hoof angle, HPA, and ...
Form and function of the equine digit. The list of possible diagnoses derived from matching anatomic structures or tissues to pathologic processes is inevitably broad in nature. Understanding and observation of distal limb function, conformation, and balance is the basis of identifying where the greatest abnormal stresses within the distal limb are likely to occur. This is key to focusing the diagnostic process and, in some instances, to treating the horse when a definitive diagnosis cannot be achieved.
Natural balance trimming and shoeing: its theory and application. The principles and techniques of natural balance trimming and shoeing are designed to optimize the efficiency and function of the foot. The basic guidelines have evolved in part from wild horse hoof imprint studies done in 1986 through 1987 and first presented in 1995. Further research has contributed to these principles and guidelines to make them applicable to domestic horses.
Hoof wall defects: chronic hoof wall separations and hoof wall cracks. Hoof wall defects in horses are common occurrences, and, fortunately, many of those detected present little or no danger to the individual horse. Those defects that are either presently a problem or have a great likelihood of being a problem do often require specialized consideration. Horse shoeing and farriery are ancient practices; over the years, a multitude of methods, theories, and management schemes have been proposed. It is unfortunate to note that few studies are available to provide an accurate incidence rate, a better understanding of the various causes, and, lastly, a comparative ap...
Diagnosis, treatment, and farriery for horses with chronic heel pain. In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event.
Foot management in the foal and weanling. Foot management and hoof care of foals, weanlings, and yearlings tends to be considered a specialist job. Many farriers and veterinary surgeons have little exposure to young and growing stock. Nevertheless, a variety of angular and flexural limb deformities can benefit from simple podiatry techniques, which can be performed provided that a few basic rules are followed. The combined skills of the farrier and veterinary surgeon offer many young horses with angular or flexural limb deformities a chance of a future athletic career.
Chronic laminitis: current treatment strategies. Laminitis is divided into four different phases: developmental, acute, subacute, and chronic. The focus of this article is on treating the laminitic horse after the cessation of therapy for the acute phase, that is, usually 2 to 4 weeks after the onset of clinical signs.
Hoof capsule distortion: understanding the mechanisms as a basis for rational management. Understanding the basic mechanisms of hoof capsule distortion enables the clinician to unravel the sometimes complex mix of abnormalities, identify early warning signs, and manage existing problems more effectively. Distortion of the hoof capsule can often seem like a complicated puzzle by the time the veterinarian is called to examine the lame horse. Evaluating each of the components of the hoof capsule, both individually and as an integrated unit, allows the clinician to tease apart the tangle of primary and secondary problems and come up with effective options for countering or attenuating ...
Foot pain and the elusive diagnosis. New information about foot anatomy, effects of local analgesia, and advances in diagnostic imaging (ultrasonography, nuclear scintigraphy, MRI, CT, and endoscopy) has opened the way for more specific diagnoses of lameness. New questions have been raised, however, and some older ideas are now in doubt. This article discusses some of these findings in the light of our own clinical experiences as they relate to diagnosis of the causes of foot pain.
Hoof repair and glue-on shoe adhesive technology. There are many different commercially available hoof repair/adhesive products. The application of these products in the treatment of various foot conditions is continuing to evolve based on sound medical and farriery principles as well as imagination. Successful application of these products depends largely on using proper hoof wall preparation and adhesive application techniques. Success also depends on a realistic expectation of the final outcome when accounting for the physical limitations of the adhesive products and the underlying hoof problem. Our results with these techniques have been ...
The role and importance of farriery in equine veterinary practice. There is a lot of room for us to become the central source of medical information regarding shoeing and lameness in our own practice area. This takes a good bit of effort and a real "outreach" to client and farrier. It can be done with the one tool we are best at--the acquisition and careful dispensing of information that we can put together regarding the health of the foot. Such information includes the following: 1. Radiographically guided hoof trimming and shoeing. 2. Ultrasonography. 3. Digital radiography. 4. Thermography. 5. Nutritional and health counseling. Become the "local" expert in...
Examination of the equine foot. The examination of the foot must be based on observations of the hoof, followed by a careful determination of areas of pain. This must be followed by an assessment of the biomechanical forces on the hoof and limb. Finally, imaging gives insight into the nature of the injury and allows the examiner to prognosticate the outcome.
Lower airway diseases of the adult horse. Lower airway problems of the adult horse are commonly encountered by the practitioner. Particularly susceptible populations include horses transported for any significant distance and young horses grouped together for training and/or competition. This article presents some of the commonly encountered problems of this patient population, including bacterial pneumonia/pleuropneumonia and influenza, and some uncommon ones, including pulmonary edema, pneumothorax/hemothorax, and acuterespiratory distress syndrome. Information is presented that should allow the practitioner to diagnose these proble...
Exercise-induced pulmonary hemorrhage. EIPH is a condition affecting virtually all horses during intense exercise worldwide. The hemorrhage originates from the pulmonary vasculature and is distributed predominantly bilaterally in the dorsocaudal lung lobes. As the condition progresses, the lung abnormalities extend cranially along the dorsal portions of the lung. An inflammatory response occurs in association with the hemorrhage and may contribute to the chronic sequela. Although conflicting opinions exist as to its affect on performance, it is a syndrome that is thought to increase in severity with age. The most commonly performed...
Tools for the diagnosis of equine respiratory disorders. Respiratory disorders are among the most common problems leading horse owners to seek veterinary attention. Accurate diagnosis of these conditions allows for proper treatment to be instituted, much to the benefit of the patient and satisfaction of the client. As an introduction to this issue on equine respiratory disorders, we review some of the tools that are available to equine veterinarians for the diagnosis of respiratory disorders. Physical and endoscopic examination, radiology, diagnostic ultrasound, techniques for sampling the respiratory tract, hematology, blood gas analysis, respirato...
The use of lasers for treatment of upper respiratory tract disorders. Lasers have become important tools for the equine surgeon in the treatment of upper respiratory tract disease in the horse. Multiple wavelengths and delivery systems are available. Indications for the use of lasers in the upper respiratory tract primarily include minimally invasive procedures not possible with conventional surgical instrumentation. New applications for the use of lasers to treat upper respiratory disease are likely to evolve with the development and introduction of new wavelengths and delivery systems.
Laryngeal reinnervation in the horse. Left laryngeal hemiplegia is a frustrating condition for the equine athlete and equine veterinarian. Treatment for the past 30 years has centered on the prosthetic laryngoplasty ("tie-back") with or without ventriculectomy. Laryngeal reinnervation has been used successfully in people and has been shown experimentally to benefit affected horses. This article reviews equine laryngeal reinnervation using the nerve muscle pedicle graft and describes the surgical technique, its complications, and the follow-up in 146 cases treated over the past 10 years. Also discussed is ongoing research into stim...
Pneumonia in weanlings. Lower respiratory tract infection is common in weanling- and suckling-aged animals. Increased susceptibility to disease in this age group can result from a delay in the establishment of a competent immune system and environmental factors, such as overcrowding, shipping, and sales. S zooepidemicus and R equi are the two most common bacterial isolates. S equi is primarily a disease of the lymph nodes and upper respiratory tract. Viral agents can compromise the natural defense mechanisms of the respiratory tract, resulting in secondary bacterial infections. The acute respiratory distress syndrome...
Disorders of the pharynx. Pharyngeal disorders are complex and difficult to treat. Disorders that lead to anatomic derangement, such as trauma and neoplasia, can significantly affect the function of this organ. Pharyngeal dysfunction can manifest as dysphagia, persistent palatal displacement, or exercise intolerance. Secondary complications are serious and life threatening and include aspiration pneumonia, weight loss, and death. Pharyngeal disorders that are only recognizable during strenuous exercise are difficult to diagnose and are treated with limited success, even though they are responsible for significant econo...
Lower respiratory problems of the neonate. The newborn foal can experience problems of the lower respiratory tract that are unique to the neonate. The transition to extrauterine life usually occurs rapidly and in a coordinated manner, but problems associated with the peripartum period, including placentitis, dystocia, infection, and trauma, can result in conditions that compromise gas exchange in the newborn foal. This article reviews the normal transition and presents some of the problems seen in these small patients.
Recurrent airway obstruction–heaves. Heaves, or recurrent airway obstruction (RAO), is a chronic respiratory disease featuring lower airway inflammation, bronchoconstriction, and mucus accumulation. Inhaled organic dusts and T helper 2 type immunologic reactions are involved in the complex pathophysiology of RAO. Clinical signs vary and alternate with remission periods. The diagnosis is often based on history and clinical examination in severe cases, but bronchoalveolar lavage may be useful for the detection of early cases. The most important aspect of treatment is to avoid exposure to allergens. Corticosteroids may be administer...
Diagnosis of upper respiratory tract diseases in the performance horse. Wastage of performance horses because of respiratory dysfunction is common. Appropriate identification of the disease is paramount for treatment recommendations. Diagnostic modalities for upper respiratory tract dysfunction include a thorough physical examination, radiographic evaluation when appropriate, and upper respiratory tract endoscopy. Anatomical deviations or structural are easily identified during resting evaluation, while exercise testing is often necessary to assess thedynamic properties of the upper airway. Utilizing the many diagnostic tools available allows the clinician to make...
Diseases of the guttural pouches. Guttural pouches are unique anatomic structures in Equidae. Conditions affecting the guttural pouches present with clinical signs that are not observed in other domestic species, and treatment of some of these conditions can be challenging. This article describes the anatomy and examination of the guttural pouches and reviews the presenting signs and treatment of the more common conditions affecting them, including empyema, tympany, mycosis, and stylohyoid arthropathy.
