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.
Harry TO, McCollum WH.The Bucyrus strain of equine arteritis virus, previously modified to avirulence and vaccinal virus by 131 serial passages in primary cell cultures of horse kidney followed by 111 passages in primary cell cultures of rabbit kidney, was further passaged in cultures of the E. Derm (NBL-6) cell line, a continuous diploid cell line. Pools of the 16th and 25th passages of the virus in this last equine dermal cell line were lyophilized and stored in lots at 37 C, 23 to 28 C, 4C, and -20 C. The viability of the vaccinal virus deteriorated rapidly during storage at 37 C and at 23 to 28 C, but was relat...
Dibb WL, Digranes A, Tønjum S.Perforation is the most serious complication of fibreoptic endoscopy.1
The commonest site of perforation during upper gastrointestinal
endoscopy is the oesophagus,' but predisposing factors have not been
fully documented. We report a retrospective survey of major endoscopy
units in the United Kingdom and attempt to identify the factors associated with oesophageal perforation.
Sack WO, Orsini PG.One hundred three equine hocks, obtained from the postmortem room, were used to study the communication and injection of material into the distal intertarsal and tarsometatarsal joints. Excluding the hocks with fused central and 3rd tarsal bones, in 8.3% of hocks injected with low (clinical) pressure and in 23.8% injected with high pressure, the distal intertarsal and tarsometatarsal joints communicated by dissection of the material through 2 internal spaces: the tarsal canal and the space between the combined tarsal bones 1 and 2 tarsal bone 3. A "pop" sometimes felt when high pressure was us...
Pascoe JR, Meagher DM, Wheat JD.Uterine torsion was diagnosed in 26 mares of various breeds. The mean duration of gestation was 9.6 months. The most common clinical history was intermittent unresponsive colic of varying duration. Diagnosis of uterine torsion was confirmed by rectal palpation, and surgical correction was achieved in most cases by standing flank laparotomy and manual repositioning of the gravid uterus. Recumbent laparotomy was used only if the mare was intractable, the uterus was ruptured, or hysterotomy was indicated. Of 20 foals determined to be alive during surgery, 14 (70%) were subsequently born alive.
Chisholm FR.A prolapsed uterus in a mare and the techniques to successfully replace the organ and prevent complications such as shock, laminitis and metritis are described.
Miller RI.Treatment of equine phycomycosis with a vaccine derived from ultrasonicated hyphae of Hyphomyces destruens was attempted in 30 cases of clinical hyphomycosis, 10 cases of hyphomycosis following unsuccessful surgery and 5 cases of basidiobolomycosis. Approximately 53% of animals with clinical hyphomycosis were cured after vaccination, while a further 33% clinically improved. All horses with hyphomycosis treated within 2 weeks of unsuccessful surgery were cured. There was no response to vaccination with a Hyphomyces preparation in horses with basidiobolomyucosis, while surgery alone resulted in ...
Craig TM, Kunde JM.Ivermectin was injected IM into 12 yearling Shetland ponies. The following reactions in percentages of parasites recovered from ponies given 200 microgram/kg or 300 microgram/kg, as compared with the parasitic population in those given the vehicle at 1 week after injection, were as follows: Otobius megnini nymphs--no reduction; Gasterophilus intestinalis--100% and 99.9%; G nasalis--100% and 99.9%; Parascaris equorum adults--100% and 96%; Strongylus vulgaris adults--100% and 100%; S edentatus adults--100% and 100%; cyathostome adults of the genera Gyalocephalus, Cylicocyclus, Cyathostomum, Cyli...
Trout DR, Lohse CL.A foal with a congenital flexure deformity of the right hock was unable to walk because of an abnormally short peroneus tertius (PT) muscle. Tension on the muscle origin and insertions limited the dorsal angle of hock extension to a 70-degrees arc. The intrauterine position of the fetus probably caused the defect. All the PT attachments were dissected in several other limbs, and illustrations made from these dissections were used to study the anatomy and surgical approach. Immediately after resection of the PT muscle, the foal's right hock extended an additional 30 degrees. Two months later, t...
Shull RM.Hemolytic or blood loss anemia was induce in six ponies and red blood cell concentrations of creatine, glucose-6-phosphate dehydrogenase (G-6-PD), lactate dehydrogenase (LDH), and aspartate transaminase (AST) were measured during the ensuing regenerative period. Creatine and G-6-PD levels correlated well and increased concentration of either was good indication of increased erythrogenesis. Erythrocyte LDH levels were of value in assessing the response to hemolytic anemia but not to blood loss anemia. The difference may be, at least in part, the result of differing degrees of regenerative effor...
Eysker M, Wemmenhove R.The epidemiology and control of helminth infections in the horse were studied in four small grazing experiments between 1981 and 1984 at the University of Utrecht. At autopsy in November or December negligible Strongylus vulgaris burdens were found in the cranial mesenteric artery of four groups of ponies, which had been treated with an anthelmintic in July and subsequently transferred to a clean pasture. Considerable arterial S. vulgaris burdens were seen in three groups of ponies which were treated with an anthelmintic in July without a move to clean pasture, and in another group of ponies i...
McIlwraith CW.The postoperative management of the surgical colic patient varies according to the complications experienced. Many of these complications can be related to the time at which surgery is performed
relative to commencement of the problem, the condition of the patient at the time of surgery, the particular condition, and, last but not
least, the surgeon's performance. Some of the points have been discussed elsewhere in the symposium. The maintenance of asepsis, attention to minimizing trauma to the bowel, and appropriate attention
to visceral and parietal closures are all important principles. ...
Abuja GA, Bubeck KA, Quinteros DD, García-López JM.The clinical signs, radiographic findings, surgical treatment, and outcome of three horses with luxation of the distal tarsal joints are reported. Two patients showed luxations of the tarsometatarsal joint whereas luxation of the proximal intertarsal joint was found in one case. Open reduction, followed by internal fixation was performed in two horses and closed reduction with a transfixation pin cast was performed in the third. The treatment in all three cases resulted in a satisfactory clinical outcome.
Yovich JV, Hilbert BJ, McGill CA.Nineteen cases of fracture of the distal phalanx in horses are reviewed. This represented 1.1% of the total number of horses seen at Murdoch University Veterinary Hospital (MUVH) over a 32-month period. All horses were managed conservatively. Eight horses made a complete recovery. Three are being trained again and are not lame. Four horses made a limited recovery. Two horses are still resting and one horse was killed humanely when it still showed lameness after 2 years. One horse was killed humanely after the fracture was first diagnosed.
