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.
The use of synthetic prostaglandin analogue to induce oestrus in mares. A clinical trial involving 359 mares was conducted to ascertain the clinical value of a synthetic prostaglandin analogue (fluprostenol, ICI-81,008) structurally related to PGF2oc for treating mares in prolonged dioestrus. Some 263 mares (73.3%) displayed oestrus within 5 days of a first intramuscular injection of 250 mug fluprostenol and, of those mares later examined for pregnancy, 108 (40%) were found to have conceived during the first induced oestrus. A further 21 mares (8%) cycled normally and conceived to services during the second oestrus. Most (80.3%) of the plasma samples obtained from...
Dropsy of the fetal sacs in mares: induced and spontaneous abortion. Eight cases of severe dropsy of the fetal sacs have been observed in mares. All were in multiparous mares whose ages ranged from five to 20 years and who were 7 1/2 to 10 3/4 months pregnant. Abortion started spontaneously in four cases and had to be induced in the remaining four by manual dilation of the cervix, rupture of the tough allantochorion and the siphoning off of 120 to 220 litres of allantoic fluid. The amnion was normal. Dystocia, due to uterine inertia, occurred in all eight cases, one hydrocephalic fetus needing fetotomy. All fetuses were alive at delivery although four were tera...
The selection of antibiotics. The usefulness of an antibiotic depends not only upon its antibacterial potency and spectrum but also on the prevalence of resistant organisms and the extent and severity of the adverse reactions to which it may give rise. Variations in formulation of the same compound are reflected in differences in bioavailability. These may be intentional, as in the development of long-acting preparations, but may also be unexpected following differences in drug purity, content and gastro-intestinal absorption. Individual and species differences in treated animals also result in variations in bioavailabilit...
Lamellar corneal transplantation in the horse. Surgical correction of corneal opacities in horses has rarely been documented in detail and is still reported to be in the experimental stage. For this reason, studies of lamellar keratoplasty were conducted on the equine eye using a modified trephine with an adjustable inside quard for grafting of identical discs from the donor and the recipient cornea. Fourteen transplantations, seven with homografts and seven with heterografts, 15 and 9 mm in diameter, were performed. Sharp-edged, vertical, and regular outlined wound margins of the graft and host are essential for good adaptation and healin...
Cryosurgical treatment of cancerous and noncancerous diseases of dogs, horses, and cats. Cryosurgery was used to treat a variety of cancerous and noncancerous diseases in dogs, horses, and cats. Follow-up evaluation on 52 animals revealed an overall "no recurrence" rate of 61%. Among the animals with no recurrence were 12 of 17 with cutaneous lesions and 5 of 8 (horses) with sarcoids. Seven of 10 dogs with anal fistulas healed after cryosurgery, but 2 had recurrence of the disease. Treatment of invasive neoplasms of the oral and nasal cavities was not successful. Side effects and complications were minimal.
Myodegeneration and suspected selenium/vitamin E deficiency in horses. The clinical, macroscopic, and microscopic features of 10 isolated cases of myodegeneration in foals were compared. Low values for selenium and vitamin E content were found in the hay and oats from one breeding stable. Serum selenium concentrations in mares at this stable were also low. Creatinine phosphokinase and serum glutamic oxaloacetic transaminase activities were increased in 2 young foals at this stable; in 1 of these foals, both enzymatic activities were markedly reduced after treatment with vitamin E and selenium. Nutritional myodegeneration was suggested as a diagnosis in this stabl...
Comparison of three techniques for intestinal anastomosis in Equidae. Thirteen horses and ponies were used to evaluate an anastomotic technique utilizing a modified Gambee suture pattern. The modified Gambee technique was compared with a single-row everting technique and a double-row inverting technique. The double-row inverting technique predisposed to intestinal obstruction and resulted in minimal adhesions. The everting technique predisposed to leakage of intestinal contents and subsequent peritonitis. Adhesions were formed at the site of the anastomosis to such an extent as to jeopardize the proper position of the bowel. The technique did not cause any lumin...
Search for persistent epizootic Venezuelan encephalitis virus in Guatemala, El Salvador and Nicaragua during 1970-1975. Evidence was sought during 1970-1975 of persistence of equine-virulent Venezuelan encephalitis (VE) virus in regions of Central America that were heavily involved in the epidemic-equine epizootic of 1969. (a) Four sentinel horses were exposed in an arid, upland region of the Atlantic drainage of Guatemala during August-October 1970, but no horse became infected. (b) The epicenter region of the 1969 outbreak, in southwestern Guatemala and southwestern El Salvador, was studied during July 1970-February 1974; no antibody developed in sentinel horses, sentinel hamsters did not die, mosquitoes yiel...
Four cases of Tyzzer’s disease in foals in England. A rodent pathogen, Bacillus piliformis, has been recognised as causing a rapidly fatal hepatitis in 4 foals in England. The disease in foals has been recognised in America since 1973. A clinico-pathological account of the 4 cases is given and the differential diagnosis discussed. The 4 foals' ages fell within a very narrow range (24-34 days). Some of the properties of this unusual intracellular pathogen are reviewed. For the first time in the equine the bacillus was seen in association with myocardial lesions. There are marked differences in the epidemiology of the disease in the mouse and in ...
Urethral sphincterotomy for delivery of vesical calculus in the mare: a case report. A case of vesical calculus in which haematuria was not a presenting sign is described. Methods of removal of vesical calculi are discussed. In this case, urethral sphincterotomy facilitated delivery.
Efficacy of Japanese encephalitis vaccine in horses. The efficacy of Japanese encephalitis vaccine in horses has been described from the effect of mass vaccination on the local prevalence of the disease in horses in each district of Hokkaido, Japan.
Percutaneous tendon splitting–method and results. The paper briefly describes the percutaneous tendon splitting operation as performed in general practice and evaluates its effectiveness on the basis of races run during a 2 year follow-up period. The results are compared with similar figures for normal Standardbred trotters. A higher percentage of horses subjected to splitting of the suspensory ligament failed to remain sound long enough to run more than 10 races during the follow-up period. The percentage of horses returning to racing whose superficial flexor was operated upon was somewhat lower than the control group.
Fractures of the pedal bone in the horse. A series of 79 fractures of the pedal bone in various types of horses are reported and the clinical features described. The fractures were of 3 types--intra-articular or extra-articular, involving the wing of the pedal bone, and fractures of the extensor process. Forty-five horses with a fractured wing of the pedal bone were treated conservatively and 11 by immobilisation of the bony fragment with a compression screw. Conservative treatment was usually successful in the extra-articular fractures. Intra-articular fractures treated conservatively in animals under 3 years had a good prognosis. Th...
Experience of the efficacy of equine influenza vaccinations. In 1974, a very extensive influenza/A/equi 2 epidemic broke out in the Finnish horse population. To study the efficacy of influenza vaccinations a questionnaire was sent after the epidemic to all Finnish veterinarians. The answer material was selected to contain only stables which had had clinically typical cases. The material consisted 234 unvaccinated and 629 vaccinated horses. In the latter group 466 horses were vaccinated adequately. The results of the study showed that of the unvaccinated horses 212 (91%) and of the adequately vaccinated horses only 42 (9.4%) contracted clinically typical...
Fluprostenol in mares: clinical trials for the treatment of infertility. Fluprostenol (ICI 81,008) is a 16-aryloxyprostaglandin, structurally related to PGF2alpha. It is a highly potent luteolytic agent, being effective in thoroughbred mares at a single intramuscular dose of 250 mug and having a wide margin of safety in this species. A total of 941 mares have been treated with fluprostenol in an international trial, for various forms of infertility associated with abnormal persistence of luteal function. These mares were selected for treatment on the basis of clinical examination and 760 (approximately 80 per cent) responded fluprostenol by showing oestrus within s...
