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.
Resistance to development of equine ehrlichial colitis in experimentally inoculated horses and ponies. Fourteen ponies and 3 horses were inoculated with Ehrlichia risticii 2 to 20 months after a similar initial inoculation. Although all 17 had clinical signs of equine ehrlichial colitis after the first inoculation, 16 of 17 remained clinically normal following the second inoculation. The remaining pony had a transient fever and developed signs of depression. Before the initial inoculation, none of the animals had a detectable antibody titer to E risticii. All animals developed titers after the initial infection; however, a significant change of titer did not develop after reinoculation in most ...
Comparison between six parasitological methods for diagnosis of Trypanosoma evansi in the subtropical area of Argentina. In a total of 165 blood samples from horses in the Province of Formosa (Argentina), the diagnosis for equine trypanosomiasis (T. evansi) was made using Giemsa-stained smears (GSS), wet blood films (WBF), Strout's concentration method (SCM), haematocrit centrifuge technique (HCT), buffy coat method (BCM) and mouse inoculation of blood (MBI). Trypanosoma evansi was demonstrated in 52 samples. Mouse inoculation gave a sensitivity of 88.2%; HCT 71.1%; BCM 63.4%; WBF 53.8%; SCM 46.1% and GSS 45.6%. No single method alone was totally effective. The haematocrit centrifuge technique, mouse inoculation...
Observer variation in equine abdominal auscultation. The reliability of abdominal auscultation was investigated via an observer variation study. Clinicians listened to a variety of minute-long equine gut sound recordings. They evaluated the amount of gut sounds as 'absent', 'decreased', 'normal', or 'increased'. They subsequently evaluated the same recordings replayed in a different order. Intra- and inter-observer agreement was measured by the statistic kappa. There was significant intra-observer (kappa 0.57) agreement, but less agreement between observers (kappa 0.37). The best agreement was on the classification of sound tracks as 'absent' (i...
Pulse oximetry in horses. The clinical usefulness of two pulse oximeters was evaluated at two probe sites in nine anesthetized horses. The hemoglobin saturation determined by the pulse oximeters (SaOx) was compared with the hemoglobin saturation calculated from the measured arterial oxygen tension (SaO2). The mean and standard deviation (SD) were calculated from the differences in saturation measurements, over the saturation range of 80% to 100%, for each oximeter used at the tongue probe site and for one oximeter used at the ear. The oximeter results tended to underestimate the SaO2 with mean differences of -3.7% on t...
Fractures of the accessory carpal bone in the horse. The clinical signs and radiographic appearance of 19 cases of fracture of the accessory carpal bone of horses are described. In 17 cases the fractures were in the frontal plane and occurred palmar to the groove on the lateral aspect of the bone. In six cases radiographs taken six months to three years after the fracture occurred showed no evidence of bony union; nevertheless, these and five other horses for which follow-up information was available for up to seven years all became sound, and seven of them returned to competitive activity.
Haematological measurements as an aid to early diagnosis and prognosis of respiratory viral infections in thoroughbred horses. In late November 1988 large numbers of thoroughbred horses in training in Hong Kong developed a transient pyrexia with, in some cases, the clinical signs of viral respiratory disease. Serial blood samples for haematological examination were taken from 10 of the horses which were stabled in six different blocks. They had developed a high temperature within three days of each other and subsequently seroconverted to equine herpes virus 1 (EHV1). The absolute monocyte count was more than 0.5 x 10(9)/litre in all 10 within the first five days, and nine of them had a high neutrophil/lymphocyte ratio...
Lameness diagnosis and treatment in the Thoroughbred racehorse. Thoroughbred racehorses are susceptible to any and all of the commonly described conditions that affect soundness in the horse. This discussion does not include every conceivable ailment or orthopedic condition that afflicts these animals. Rather, it confines itself to a few specific conditions of the racing Thoroughbred that are either unique to their particular endeavor or so overwhelmingly important to a successful racing career that they must, of necessity, be discussed.
Surgery of the upper respiratory tract in the racehorse. The authors discuss the surgical treatment of selected diseases of the upper airway of the racehorse. Although most of these conditions occur commonly and are easily diagnosed, their surgical management is often less straight-forward and may be surprisingly controversial. The authors' intent is to provide an overview of these problems and give some information regarding current treatment options.
Traumatic disruption of the suspensory apparatus in foals. Traumatic disruption of the suspensory apparatus is a catastrophic injury in the horse. Although this injury has been described in the adult, little information is available in the foal. This paper describes 3 foals with metacarpophalangeal joint instability caused by traumatic disruption of the suspensory apparatus. Two foals had biaxial proximal sesamoid fractures in a single forelimb, and 1 foal had avulsion of the distal sesamoidean ligaments in 1 forelimb plus biaxial proximal sesamoid fractures in the other forelimb. The foals with single forelimb involvement were managed with splints, a...
Respiratory problems in the racehorse. Racetracks are ideal environments for the promotion of lower respiratory disease. The stabling is close and unclean, the population is nationally and internationally mobile, and the work the racehorse performs is traumatic to the respiratory tract. The running horse must complete a respiratory cycle with each stride. This relationship requires 130-150 breaths a minute in the running horse. Minute volume has been measured at 1300 L per minute and peak flow rates of 60 L/second in horses traveling at a modest 8 meters per second. As a comparison, the fastest running horse approaches 18 meters pe...
Propafenone kinetics in the horse. Comparative analysis of compartmental and noncompartmental models. The propafenone kinetics after intravenous (i.v.) administration have been studied in the horse by a comparative analysis of compartmental and noncompartmental models. The pharmacokinetic parameters showed a large distribution (Vdss = 1021 +/- 211 L) and a high clearance (CI = 7019 +/- 1746 mL/min) of the drug. The plasma concentrations were very low, under 1 microgram/mL, in most cases; after 30 min these concentrations can be considered as nonefficient for the treatment of arrhythmia. There were no significant differences between pharmacokinetic parameters found with the use of compartmental...
Gamma scintigraphic analysis of the distribution of perfusion of blood in the equine foot during black walnut (Juglans nigra)-induced laminitis. Twelve horses, with acute laminitis (primarily in the forefeet) at 12 hours after intragastric dosing with an aqueous extract of black walnut (Juglans nigra) heart-wood, were studied. The distribution of perfusion of blood to the foot and to outlined regions within the foot was quantified, using gamma scintigraphy of regionally infused 99mTc-labeled macroaggregated albumin, before and 12 hours after extract administration. Horses 1 to 3 were not studied further. Perfusion was quantified again for horses 4 to 12 at 84 hours after extract administration. At the onset of acute laminitis, horses 7...
[Ovarian structure and function in the mare from the clinical viewpoint with special regard to ultrasonography]. Ultrasonography is a good means of monitoring follicular development in the mare and allows objective observation and measurement of follicular growth as well as identification of corpora lutea and hematoma in the ovary. The significance of ultrasonography in this field lies in the specific anatomical structure of the mare's ovary and the different phenomena preceding and accompanying ovulation, which are described in this paper. The last part deals with the handling and use of ultrasonography.
[Endodontics in horses. An experimental study]. A total of 44 experimental endodontic treatments were performed in incisors of eight horses of different ages. Four different endodontic pastes were used: Cloropercha, AH26 De Trey, Eugenol-Endometasone, and Universal N2. Gutta-percha points were also included in the last two treatments. Access to the pulp cavity of incisors was gained through their vestibular and occlusal faces. Holes drilled in vestibular faces were sealed with composite and those drilled in occlusal faces were sealed with Amalgama. Animals were observed during eighteen months at least after endodontics. Radiographic control...
Ehrlichiosis–a disease of animals and humans. Ehrlichiae are one of several kinds of obligate intracellular bacteria. Taxonomically, they are grouped with rickettsiae, but they can be distinguished by their unique tropism for circulating leukocytes. Ehrlichia canis causes a pancytopenia in dogs that becomes chronic if untreated. Certain breeds develop severe infections, characterized by fever, anorexia, dramatic weight loss, marked pancytopenia, anemia, peripheral edema, and hemorrhage. Ehrlichia risticii, a recently discovered species, is the cause of a serious diarrheal disease of horses. Other species of ehrlichiae have been documented...
[Veterinary examinations of horses during purchase transactions]. Veterinary examinations of horses on the occasion of sale or purchase take place on the basis of contracts for work and services. Three types may be distinguished: Examinations for sale (by order of the seller before the sales contract is concluded) Guarantee examination (by order of the buyer after conclusion of the sales contract) (Real) purchase examination (under a conditional contract of purchase). In the latter case the veterinarian acts as trustee for both seller and buyer and is equally obliged to both parties morally and at law. The deficiencies of the law of warranties for contracts ...
Lameness diagnosis and treatment in the Standardbred racehorse. Lameness of the Standardbred racehorse is a function of rigorous training programs, year-round racing schedules, hard racetrack surfaces, and the draft load. In this article, principles of lameness diagnosis and treatment are reviewed, with emphasis upon common or unique problems of the trotter and pacer. The role of physical therapy as an adjunct to medical and surgical treatment of lameness is described. Options for management of chronic pain are discussed, and a limited glossary of descriptive terms that are unique to harness racing is provided.
Sequential mesenteric arteriography in pony foals during repeated inoculations of Strongylus vulgaris and treatments with ivermectin. Semiselective mesenteric arteriography was performed at regular intervals (inoculation weeks [IW] 0, 11, 18, and 24) in 9 of 10 pony foals raised to be free of parasites. Fifty infective larvae (L3) of Strongylus vulgaris were administered weekly for 4 weeks, then every 2 weeks through the 20th week. Three ponies were given ivermectin (oral paste, 0.2 mg/kg of body weight) treatment at IW 8, 16 and 24. Four ponies were inoculated, but did not receive ivermectin, and a third group of 2 ponies acted as uninoculated controls. Control ponies did not have gross or arteriographic lesions, whereas th...
Trajectory analysis of winds and vesicular stomatitis in North America, 1982-5. Outbreaks of vesicular stomatitis, serotype New Jersey, during epidemics in the United States and northern Mexico, 1982-5, were examined by backward trajectories of winds to investigate spread and possible sources. The outbreaks selected for analysis did not involve introduction of disease by infected animals. The findings indicate that wind could have been responsible for carrying infection from northern Mexico to Arizona and New Mexico and thence to Colorado and Utah and on to Wyoming, Idaho and Montana. The results of these analyses are consistent with the findings from T1 RNAse fingerprint...
Lameness diagnosis and treatment in the quarter horse racehorse. Lameness problems constitute a major part of racing Quarter Horse practice. This article considers the diagnosis, prognosis, and treatment of the frequently encountered lamenesses. The main conditions included are synovitis, intra-articular fractures, osteochondritis dissecans, and degenerative joint disease as they relate to the coffin, fetlock, carpal, and tarsal joints. Intra-articular injection techniques and medications are discussed because of the frequency of joint disease. Bucked shins and stress fractures are also reviewed.
Anaerobic bacterial pneumonia with septicemia in two racehorses. Anaerobic bacterial pneumonia with septicemia was diagnosed in 2 Thoroughbred racehorses referred with respiratory tract disease that had failed to respond to initial treatment with various antibiotics including penicillin and trimethoprim-sulfamethoxazole. Multiple anaerobic organisms, including Bacteroides spp and Fusobacterium spp, were isolated from blood and transtracheal aspirates obtained from both horses and from aspirates of cutaneous nodules obtained from 1 horse. The latter horse responded to metronidazole treatment followed by procaine penicillin G administration and regained its h...
Upper airway function during maximal exercise in horses with obstructive upper airway lesions. Effect of surgical treatment. Upper airway pressure was measured during maximal exercise in 10 Thoroughbred racehorses with naturally occurring upper airway obstruction. Left laryngeal hemiplegia and arytenoid chondropathy resulted in substantial increases (30-40 cm H2O) in inspiratory upper airway pressure (Pl), whereas complicated aryepiglottic entrapment and subepiglottic cysts produced only modest increases (15 cm H2O) in Pl. Uncomplicated aryepiglottic entrapment and grade IV pharyngeal lymphoid hyperplasia produced only slight increases (3-5 cm H2O). In general, surgical procedures restored airway pressures to within...
Surgical repair of tibial tuberosity avulsion fractures in four horses. Four horses, 2 to 17 years old, were treated for unilateral avulsion fractures of the tibial tuberosity. Two horses were treated successfully with tension band wiring or plating in combination with lag screw fixation. One horse was euthanatized because of implant failure during recovery and one was euthanatized on day 11 because a longitudinal fracture of the tibial tuberosity occurred through the plane of the screws used for stabilization.
