Topic:Disease Treatment
Disease treatment in horses encompasses a range of medical interventions and management strategies aimed at addressing various health conditions affecting equine species. These treatments can include pharmacological approaches, such as the administration of antibiotics, anti-inflammatory drugs, and antiparasitic medications, as well as non-pharmacological methods like physical therapy, dietary adjustments, and surgical procedures. The selection of appropriate treatments depends on the specific disease, its severity, and the individual needs of the horse. This topic brings together peer-reviewed research studies and scholarly articles that explore the efficacy, safety, and advancements in therapeutic options for equine diseases, providing insights into best practices and emerging trends in equine veterinary medicine.
Insurance of horses and the role of the veterinary surgeon. Various type of insurance policies covering the risks against mortality, economic slaughter and loss of use, breeding failures and payment of veterinary fees are discussed. The role of the veterinary surgeon in supplying certificates of health and in relation to claims, including those involving destruction on humane grounds, are considered.
Recent experience with heart transplantation. The major factors contributing to the recommencement of clinical heart transplantation in the United Kingdom last year were the steadily improving results from Stanford University, the clarification of the diagnosis of brain death, and advances in preserving donor hearts. Twelve men aged 16 to 52 years received heart transplants at Papworth Hospital from January 1979 to July 1980. Six had cardiomyopathies and six ischaemic heart disease. The donors were aged 16 to 35 (mean 21) years. A combination of road and air transport was used to transport the heart to Papworth in seven cases. The total d...
Intravenous anaesthesia in horses after xylazine premedication. The effects of combining large doses of xylazine (1.1 mg per kg intravenously) with ketamine, methohexitone and thiopentone were studied in four experimental ponies. Onset of anaesthesia was more delayed after ketamine than after the barbiturates. Assessment of smoothness of induction and recovery indicated that all three combinations were effective and acceptable. Injection of xylazine was followed by atrioventricular (A-V) block which could be prevented by the prior administration of atropine. Blood pressure was well maintained with all three combinations of drugs. Arterial oxygen tension de...
Moldy sweetclover poisoning in a horse. A six year old Percheron mare was presented with a history of spontaneous unilateral epistaxis of 24 hours duration. The blood one stage prothrombin and partial thromboplastin times were markedly prolonged. A diagnosis of moldy sweetclover poisoning was made on the basis of the history and clinical and laboratory findings. A single whole blood transfusion and four daily intravenous injections of vitamin K(3) proved to be a successful treatment.
Turnover of 131I-labelled albumin in horses with gastrointestinal disease. Four horses with a history of chronic diarrhoea and weight loss were studied. Three of them revealed malabsorption, as indicated by decreased absorption of D(+)-xylose. Three patients had distinct hypoalbuminaemia, and 131I-albumin turnover rates of these three horses were increased, compared to two normal control horses. However, the increases were not very marked, probably because actual signs of enteric disease were few in the patients, all of which were studied during convalescence. It is suggested that the observed hypoalbuminaemia is due to a gastrointestinal protein loss during the chro...
Contagious equine metritis: isolation and characterization of the etiologic agent. Uterine, cervical, and clitoral specimens on swabs from pony mares infected with contagious equine equine metritis (CEM) bacteria were streaked on agar plates. Colonies of CEM bacteria were observed under CO2 incubation in 2 days on Eugon chocolate agar and Eugon blood agar plates. The diameter of the colonies varied from 0.2 mm to 1 mm in 2 days which increased to 0.3 mm to 2.0 mm on day 4. The colonies on Eugon chocolate agar plates on days 2 to 4 were shiny, brown, round, and convex, and easily glided when pushed with a loop. The diameter of the colonies on chocolate and blood agar plates m...
Repair of digital flexor tendon lacerations in the horse, using carbon fiber implants. Flexible medical grade carbon fiber was surgically implanted in tenectomized or lacerated superficial and deep digital flexor tendons of 13 horses (7 clinical cases and 6 experimental), ranging in age from 15 months to 10 years and weighing 300 to 500 kg. The 6 experimental horses were euthanatized at 30-, 45-, 60-, and 90-day intervals for gross and histologic evaluation of the results. Three of the experimental horses served as their own controls. Of the 7 clinically affected horses, 3 were euthanatized because they developed laminitis or the wound failed to heal. The remaining 4 horses in t...
Intestinal atresia and stenosis in animals: a report of 34 cases. Intestinal atresia was found in 29 animals and stenosis in five. Atresia was found in the duodenum in one pup; in the jejunum in nine calves, two lambs and one piglet; in the ileum in one pup, one lamb and one piglet; and in the colon in one foal, seven calves, one lamb, one piglet and three kittens. Stenosis was found in the duodenum of a foal, in the jejunum in two calves and one pup, and in both the ileum and the colon of a kitten. One lamb showed ileal atresia as well as ileal stenosis. We classified the atresia as type 1, membrane atresia (four cases); type 2, cord atresia (six cases); an...
Critical tests of new benzothiazole anthelmintic tioxidazole in the horse. The basic-dose confirmation tests of tioxidazole for removal of susceptible populations of gastrointestinal parasites of the horse were made in 10 naturally infected horses, using the critical test method (experiment A). A single dose of toxidazole, given at the rate of 11 mg/kg of body weight, was administered to 5 horses by stomach tube and to 5 horses by mixing the drug with the daily grain ration. In the 5 horses given the drug by stomach tube, aggregate average removals were 90% or more for 5 horses infected with Stronglyus vulgaris, 5 infected with S edentatus, 5 infected with small stro...
Equine Getah virus infection: isolation of the virus from racehorses during an enzootic in Japan. A primary enzootic of equine Getah virus infection involving 722 of 1,903 racehorses occurred at a training center in Japan between September and November of 1978. Sixty-two viral agents were isolated from the plasma of 209 sick horses which exhibited pyrexia with rectal temperatures ranging from 38.5--40 degrees C, urticarial rash on various portions of the body, and edema of the hind legs. The viruses were antigenically related to the AMM 2021, Haruna, and Sagiyama strains of Getah virus. Infection and disease were produced experimentally in horses when inoculated by the intramuscular or int...
An epidemic of Getah virus infection among racehorses: properties of the virus. A virus (Sakai) which had been recovered from an outbreak of disease in horses was found to be a small spherical enveloped RNA virus with a diameter of approximately 70 nm and a buoyant density of 1.22 g per ml. It grew well and produced a cytopathic effect in a variety of cell cultures; it was sensitive to organic solvents, heat and low pH. It agglutinated goose erythrocytes in a 0.35 M sodium chloride solution at an optimum pH of 6.2 and was antigenically identical or closely related to Getah virus, a member of the alphavirus subgroup of the Togaviridae.
Traumatic balanoposthitis in a yearling Appaloosa colt. A case of balanoposthitis involving injury to a yearling colt's penis and prepuce is described. Details are given of the Vennerhalm or reefing operation which was used to relieve the penile prolapse and paraphimosis accompanying the condition.
Crystalline inclusions in erythrocytes parasitized with Babesia equi following treatment of ponies with imidocarb. Four splenectomized Welsh ponies were infected with Babesia equi. Two ponies were treated with imidocarb dipropionate, and two were not treated. By light microscopic examination, 1% to 2% of the parasitized erythrocytes of treated ponies contained crystalline inclusions. The crystals were rectangular, diamond, or burr shaped. They occupied most of the erythrocytic cytoplasm, and, as a result, the remainder of the pale staining cytoplasm was inconspicuous in Wright-Giemsa-stained blood smears. The size and shape of intraerythrocytic inclusions varied when examined by electron microscopy, but in...
[Use of trichlorfon as an anthelmintic in horses (author’s transl)]. The use of trichlorfon as an anthelmintic in horses has increased since it was combined with mebendazole and febantel, and became commercially available as Telmin-trichlorfon and Rintal-plus respectively. Field studies showed that these combined preparations frequently gave rise to cases of poisoning. Mild to severe colic was observed up to six hours after treatment, diarrhoea and/or anorexia continuing to be present for one to six days after administration. The 'horse weight measurer' introduced by Janssen Pharmaceutica is not sufficiently accurate to prevent overdosage. It is advisable only ...
Principles of drug administration in the horse. This paper is an introduction to a series of commissioned articles on therapeutic medicine to be published in Equine Veterinary Journal under differing authorship, during the next 2 years. It presents an account of fundamental concepts common to the use of all drugs and introduces some pharmacokinetic principles to which reference will be made in later articles.
