Topic:Veterinary Practice
Veterinary practice in relation to horses encompasses the medical care, management, and treatment of equine species. This field involves various aspects of equine health, including preventive care, diagnosis, and treatment of diseases, surgical interventions, and emergency care. Equine veterinarians employ a range of diagnostic tools and techniques such as physical examinations, imaging, and laboratory tests to assess and monitor horse health. In addition to addressing physical ailments, veterinary practice also includes nutritional management, reproductive health, and performance-related issues. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, advancements, and outcomes in veterinary practices specific to equine health.
Systemic therapies for joint disease in horses. Systemic therapies for joint disease may be prescribed when a single joint is involved or when multiple sites are affected. The precise therapeutic regimen recommended depends on the duration,cause, and site(s) of injury and is often an adjunct to intra-articular or supportive therapies. If the clinical signs of joint disease are acute and moderate in severity, nonsteroidal anti-inflammatory drugs are often administered to alleviate pain and inflammation. When aiming for more of a generalized maintenance or chondro-protective regimen, an alternative medication, such as hyaluronan,polysulfated ...

A novel method to estimate the stiffness of the equine back. Diagnosis of back problems in equine orthopedics can be a difficult task. The aim of our study was to develop a new method for estimating the stiffness of the equine back in vivo. We measured the activity of the long back muscle at two locations on both sides at thoracic vertebrae T12 and T16 of 15 horses flexing and extending their back at stance using telemetric surface electromyography, while simultaneously recording the motion of the back with a video camera system. Out of these paired data sets we computed a transfer function in the frequency domain and evaluated its capability of capturi...
Estimation of heritability for Tying-up syndrome in the Thoroughbred racehorse by Gibbs sampling. Tying-up is a condition that primarily affects the muscles of horses. In this study, the heritability of the Tying-up syndrome in the Thoroughbred racehorse was estimated by Bayesian analysis with Gibbs sampling based on the threshold model for binary traits. The data used were the clinical data in racehorses diagnosed by veterinarians of the Racehorse Clinics of Japan Racing Association from 2000 to 2003. The health status of the Tying-up was treated as a binary trait. In the genetic analysis, the effect of changing the amount of the pedigree or inbreeding information on the estimation of her...

Equine neonatal sepsis. Neonatal infection remains a leading cause of morbidity and mortality in the equine industry, despite advances in prevention and treatment. Many factors can influence a foal's risk for the development of sepsis in the peripartum period. This article discusses those factors, causative organisms, and therapeutic options. Factors that influence prognosis and potential preventative strategies also are addressed.
Equine neonatal thoracic and abdominal ultrasonography. Pathologic disorders of the equine neonate often develop shortly after foaling as a result of prematurity, dystocia, trauma, or septicemia. Recognition of these disorders requires routine patient assessment along with diagnostic aids, including abdominal and thoracic ultrasonography. Fortunately, modern technology affords today's equine practitioners the opportunity to use ultrasonography to advance their practice, and it is the authors' hope that this article might help in those efforts.
Orthopedic disorders in neonatal foals. The first month of life is a vulnerable time for foals. They must adjust to their environment while they are still compromised immunologically, and their musculoskeletal system is rapidly growing and adjusting to stresses from an increasing amount of exercise. Therefore, if a foal is born with or acquires an abnormality or disease related to the musculoskeletal system, rapid adjustments must be made to allow the foal to grow and respond so that future athletic performance will not be compromised. Problems must be identified early, which requires thorough examinations. This article summarizes t...
Nutritional support for neonatal foals. In recent years, equine neonatal medicine has made significant advances. The importance of nutritional support for the sick neonatal foal has been recognized, and methods of providing that sup-port have been developed. Today, the clinician has many options when designing a nutritional plan for the neonatal foal. When the foal's gut permits, enteral diets are an inexpensive source of nutrients. Under conditions where the gut requires rest, methods for delivering nutrients by the parenteral route have also been developed. In this article, the nutrition of the normal and sick foal is described. G...
Resuscitation and emergency management for neonatal foals. Early intervention can dramatically alter outcome in foals. Cardio-pulmonary cerebral resuscitation can be successful and clinically worthwhile when applied to foals that arrest as part of the birthing process. Readily available equipment and an ordered plan starting with addressing the respiratory system (airway and breathing) followed by the circulatory system (circulation and drugs) are the keys to success. Hypoglycemia is common in foals that are not nursing and in septic foals. Support of serum glucose can be an important emergency treatment. Respiratory support with oxygen therapy should...

Serum concentrations of KBr were measured to construct concentration versus time curves and to calculate pharmacokinetic parameters. Treated horses ...
Pharmacokinetics and pharmacodynamics of pantoprazole in clinically normal neonatal foals. Proton pump inhibitors (PPIs) are a mainstay of treatment for acid-related ulceration in man and horses. Currently, only an oral preparation of omeprazole is approved for use in horses in the USA. Intravenous administration of a PPI would provide a useful therapeutic alternative for those foals in which oral medication is not feasible. Objective: To investigate the pharmacokinetics and pharmacodynamics of pantoprazole following i.v. or intragastric administration in healthy neonatal foals. Methods: Seven healthy foals age 6-12 days at the start of the study were evaluated. Treatments included ...
End-to-end jejuno-ileal anastomosis following resection of strangulated small intestine in horses: a comparative study. Small intestinal resection and anastomosis is a relatively common procedure in equine surgical practice. This study was designed to test objectively the subjective opinions of surgeons at the Liphook Equine Hospital that an end-to-end jejuno-ileal anastomosis (JIA) is an effective and clinically justifiable procedure, contrary to conventional recommendations. Objective: An end-to-end JIA carries no greater risk of morbidity and mortality than an end-to-end jejunojejunal anastomosis (JJA). Methods: A retrospective observational study was performed on a population of 100 horses that had undergon...
Use of web-based data collection to evaluate analgesic administration and the decision for surgery in horses with colic. There is no current veterinary information with regard to data entry on a website. We therefore completed a prospective study on use of analgesics in relation to the need for abdominal surgery using a web-based survey instrument. Objective: To establish an internet-based data entry system that could be used to record prospective data on horses with colic. Objective: Failure of horses to respond to the initial administration of an analgesic is an indicator of the need for abdominal surgery. Methods: A survey was developed to determine if the response to administration of an analgesic during a v...
2nd FY Khoo Memorial Lecture. Brachytherapy–one man’s meat, a personal journey in radiation oncology. The Lecture covers the author's personal experience in brachytherapy in radiation oncology, beginning with low-dose rate (LDR) treatments using 226Ra "hot" sources, in the 1960s and early 1970s, through manual afterloading for treating gynaecological cancers with the same sources in the 1970s and 1980s, to high-dose rate (HDR) remote afterloading on a microSelectron HDR machine, from 1989 on. This progression in brachytherapy is discussed, and specific applications to various tumour sites are presented, including long-term results of a personal series of 106 patients with cancer of the uterine...
