Topic:Therapeutic Intervention
Therapeutic intervention for horses encompasses a range of treatments and management strategies aimed at addressing various health conditions and enhancing overall equine well-being. These interventions may include pharmacological treatments, physical therapies, surgical procedures, and alternative therapies such as acupuncture and chiropractic care. The selection of appropriate therapeutic interventions is guided by the specific needs of the horse, the nature of the condition being treated, and evidence-based practices. This topic includes a collection of peer-reviewed research studies and scholarly articles that explore the efficacy, methodology, and outcomes of different therapeutic interventions in equine medicine.
In vitro model of equine muscle regeneration. Equine satellite cells are responsible for muscle healing and regeneration in the mature horse. We describe the in vitro cell culture conditions required for clonal populations of equine satellite cells to undergo both proliferation and differentiation. Our hypothesis is that these in vitro conditions model regeneration of muscle and can be used to evaluate potential therapeutics. In this study, 2 areas of satellite cell response were tested: proliferation of clones induced by growth factors, and fusion induced by culture conditions. Equine satellite cell clones showed differences in their res...
[Regulation of atrial fibrillation in horses with oral quinidine sulfate. Discussion of the disease picture in a typical case]. Atrial fibrillation is a disorder of cardiac rhythmicity, and its importance in the horse depends on the underlying cause and the function of the horse. Before the decision is taken to start treatment, it has first to be ascertained whether treatment is worthwhile and whether the horse is an appropriate candidate for treatment. This article gives a short overview of current opinion on the cause and treatment of atrial fibrillation in the horse. The most used treatment at the moment, oral chinidine sulphate, is discussed. The hemodynamic consequences of atrial fibrillation and the response of a...
Therapeutics of musculoskeletal disease in the horse. Therapeutic medications play a crucial role in the successful therapy of many musculoskeletal diseases that occur in horses. For example, appropriate antibiotic therapy is extremely important in the treatment of diseases caused by infections with microorganisms such as botulism, tetanus, osteomyelitis, and muscle abscesses. In addition, numerous prescription medications and nutritional supplements are available for the treatment of osteoarthritis in horses. Many of these agents currently on the market fall into a new class of drugs called SADMO agents. Unfortunately, the efficacy and mechanism...
Acupuncture as a treatment modality for back problems. Concepts of acupuncture in traditional Chinese medicine are presented for clarity and contrast to Western medical concepts. Various acupuncture techniques and methods are discussed including dry needling, electroacupuncture, acupuncture using hypodermic needles, and injecting various solutions into the acupuncture sites. Potential complications and precautions are also presented. A type of chronic back pain is discussed that is possibly associated with a radiculopathically induced, hypersensitivity myofascial syndrome that presents as a fibromyalgia-like syndrome. Effective acupuncture treatme...
Digital perfusion, evaluated scintigraphically, and hoof wall growth in horses with chronic laminitis treated with egg bar-heart bar shoeing and coronary grooving. Nuclear scintigraphy was used to assess digital perfusion before and after treatment in 10 horses with clinical and radiographic evidence of chronic laminitis. Horses were evaluated for lameness, degree of distal phalanx rotation, and heel-toe hoof wall growth ratio, and randomly divided into two treatment groups. Group 1 horses received only egg bar-heart bar shoeing; Group 2 underwent egg bar-heart bar shoeing and coronary grooving. Horses were re-evaluated for digital perfusion, lameness, degree of distal phalanx rotation, and hoof wall growth at 6 week intervals over the 18 week follow-up ...
[Equine Cushing syndrome (ECS). Case report, review of its diagnosis and therapy and substantial differences from Cushing syndrome in dogs]. Equine and canine Cushing's syndrome, both of which are the result of elevated cortisol levels, show some different pathogenetical and clinical features and require different therapeutical approaches. In older horses the equine Cushing's syndrome (ECS) is not uncommon. Nearly all cases result from excessive hormone production in cells of the pars intermedia of the pituitary. Besides elevated levels of adrenocorticotrope hormone (ACTH), high peripheral levels of pro-opiomelanocortin, beta-endorphines and alpha-melanocyte-stimulating hormone can be measured. In middle-aged and geriatric dogs, Cu...
Aerosol deposition in equine lungs following ultrasonic nebulisation versus jet aerosol delivery system. Therapeutic aerosols pay an increasing role in the treatment of equine respiratory disorders. This route of delivery permits concentration of significant amounts of drugs at the site of action without unwanted high systemic concentration and resultant side effects. The efficiency of such a topical therapy depends on the quantity of inhaled drugs deposited in the lungs and, for some drugs, on the proportion retained in specific parts of the lungs. The objective of this study was to define and to compare quantitative (dose deposited) and qualitative (regional distribution) deposition of an aeros...
[The plasma level of kanamycin after intravenous and intramuscular injections in horses]. A therapeutical dose of kanamycin was tested intravenously and intramuscularly in four normal standardbreds and plasma concentrations were measured over a 12 hour period. Plasma levels exceeded a minimum inhibitory concentration of 4 micrograms/ml within only 15 minutes for 8 hours both after i.v. and i.m. injection. Kanamycin revealed a mean plasma half life of 2.3 hours. Bioavailability of an intramuscular dose was about 76%. The pharmacokinetic parameters demonstrate the rapid onset of antibacterial plasma levels of the test compound. A dose regimen for horses of two times daily 5 mg/kg bod...
The immunology of companion animals: reagents and therapeutic strategies with potential veterinary and human clinical applications. There is now a wide range of immunological reagents that can be used in the diagnosis and treatment of diseases in the companion animals (dogs, cats and horses). Many of these diseases are the veterinary equivalents of human conditions, and may therefore provide good models to study basic pathogenic mechanisms.
Viscosupplementation: a new concept in the treatment of osteoarthritis. Viscosupplementation is a new medical concept that has as its therapeutic goal the restoration of rheological homeostasis in pathological structures such as osteoarthritic joints. When the normal viscoelasticity of a solid tissue compartment or the elastoviscosity of a liquid tissue compartment is decreased under pathological conditions, normal function and regenerative processes are impaired. By introducing viscosupplementary devices, the normal rheological state of such compartments is restored or augmented. These devices stay in the tissue compartment for various periods of time, depending ...
Intraarticular hyaluronan injections in the treatment of osteoarthritis: state-of-the-art review. Viscosupplementation (restoring the rheological properties of a tissue matrix) by injection of hyaluronan into the joints has been in use for 2 decades, mostly for osteoarthritis (OA) of the knee, using doses of 20-25 mg of hyaluronan of 500,000 to 2,500,000 M(r), in sequences of 2 to 10 weekly injections. Pain relief appears in a few days, progresses over a few weeks, and often lasts several months. Some data suggest the benefit can last 6 months to one year. Tolerance is universally reported as very good. Those responding to hyaluronan are 65-80%, compared to 30-35% responding to control. Co...
A comparison of the traditional Chinese versus transpositional zangfu organ association acupoint locations in the horse. The traditional Chinese (TC) and transpositional (TP) methods of animal acupoint location result in different acupoint charts. Representative TC and TP equine zangfu organ shu-association acupoint charts are compared to each other and to a human chart. Despite their differences, practitioners of both methods appear to achieve equally effective therapeutic results--a phenomenon termed "traditional Chinese/transpositional equal efficacy" (TTEE). Common veterinary acupuncture practices, traditional Chinese medical theory, spinal cord anatomy, and a preliminary equine "association segment" chart a...
Principles of therapeutics. Topical administration of drugs is the treatment of choice for diseases of the anterior segment. Drug levels attained by this means are usually of short duration, however, necessitating frequent therapy or continuous perfusion if prolonged drug levels are required. A drug-delivery device (collagen shield or contact lens) or subconjunctival injections can be used to augment topical therapy if frequent treatment is not possible. Subconjunctival injections are recommended for drugs that have low solubility and, hence, low corneal penetration. Retrobulbar injections are seldom indicated, except fo...
Pharmacologic considerations in drug therapy in foals. Rational drug therapy in the foal requires a sound knowledge of the pharmacodynamics and pharmacokinetics of various drugs as well as a thorough understanding of the physiologic differences that exist between the neonate and the adult and that may serve to alter drug disposition and, therefore, drug response. A summary of these physiologic factors with emphasis on the foal is presented and is followed by recommendations regarding the applied therapeutics of various antimicrobial agents.
Effect of the injection site on the pharmacokinetics of procaine penicillin G in horses. The plasma penicillin concentrations were determined in 5 horses given an IV injection of sodium penicillin G; plasma penicillin concentrations were also determined in a crossover experiment, where animals were given procaine penicillin G subcutaneously at 1 site and IM at 4 sites. The mean penicillin plasma peak concentration and bioavailability were highest after the drug was injected in the neck and biceps musculature. Injections in the gluteal muscle and in the subcutaneous sites resulted in similar, but lower, more persistent penicillin plasma concentrations and a lower bioavailability th...
Warfarin: a review with emphasis on its use in the horse. Warfarin or dicoumarol prevents the production of functional clotting factors II, VII, IX and X. Navicular disease and thrombophlebitis are examples of equine thrombotic diseases in which warfarin has been used therapeutically. The initiation of anticoagulant therapy is relatively simple but attending veterinarians must be aware of the potential risks in order to minimize them. These risks include epistaxis, bleeding into the gastrointestinal tract and at the venipuncture site, and increased susceptibility to hematoma formation following local trauma. Vitamin K, especially vitamin K(1) is a sw...
[The use of amikacin in the treatment of endometritis caused by Pseudomonas aeruginosa in mares]. After isolation of Pseudomonas aeruginosa from endometrial biopsies of 6 mares they were treated with amikacin sulphate. Three were treated by intra-uterine application of the drug, in one the drug was given by intramuscular injection, in another the intravenous route was used while in the last mare simultaneous local and intravenous treatment was applied. An intra-uterine Tris-EDTA instillation preceeded the uterine amikacin instillations to aid in the breakdown of the capsule around the bacterium. Serum concentrations of amikacin were determined after intravenous and intramuscular administra...
Chronic tenosynovitis of the extensor tendons and tendon sheaths of the carpal region in the horse. Seven cases of chronic tenosynovitis affecting the extensor carpi radialis or lateral digital extensor tendon and their sheaths are described. All cases were chronic and in 4 of the cases previous treatment by drainage and local corticosteroid injection had been ineffective. Surgical exploration of 6 cases demonstrated a distinct lesion and specific surgical treatment was carried out.
