Treatments for horses encompasses a range of medical and therapeutic interventions aimed at maintaining or restoring equine health. This field involves the use of pharmaceuticals, surgical procedures, and alternative therapies to address various conditions affecting horses. Common treatments include the administration of anti-inflammatory drugs, antibiotics, and vaccines, as well as physical therapies and nutritional management. Research in this area focuses on evaluating the efficacy, safety, and outcomes of different treatment modalities. This page collects peer-reviewed research studies and scholarly articles that explore the methods, advancements, and clinical outcomes associated with equine treatment practices.
Pilsworth RC, Shepherd MC, Herinckx BM, Holmes MA.During a two year period, sagittal fractures of the wing of the ilium were diagnosed in 10 Thoroughbred horses. All were spontaneous fractures sustained during normal exercise in training and racing, with no history of inciting trauma. When ultrasound scans of the surface of the pelvis were performed, the fracture was clearly visible as a discontinuity of the sacral wing of the ilium. In 3 horses, an irregular contour suggestive of periosteal callus was seen in the vicinity of the acute fracture. All horses examined by gamma scintigraphy had a focal increase in uptake of isotope just lateral t...
MacAllister CG, Lowrey F, Stebbins M, Newman MS, Young B.The ponies were apparently healthy and 6-20 months of age. In Study 1, gastric lesions were created by transendoscopic electrocautery in the non-glandular gastric mucosa, adjacent to the margo plicatus in 9 ponies which were then treated with water, 12 mg cimetidine HCl/kg bwt or 18 mg cimetidine HCl/kg bwt per os every 12 h for 35 days. In Study 2, gastric lesions were similarly induced in 9 ponies in the non-glandular mucosa and also in the glandular mucosa just below the non-glandular lesion on the greater curvature of the stomach. The ponies were treated with water, 8 mg cimetidine/kg bwt ...
Browning AP, Collins JA.Combinations of romifidine and butorphanol were used to sedate 55 horses for a variety of surgical, therapeutic and diagnostic procedures. Eighteen of the horses were given the drugs separately, romifidine first followed by butorphanol four minutes later, and 37 were given the drugs together. The levels of sedation and ataxia were assessed and graded, and there were no statistically significant differences between the two methods of administration. The side effects were typical of the alpha-2 agonists, including bradycardia, heart block and some sweating. Box-walking was observed in one horse....
Madison JB, Garber JL, Rice B, Stumf AJ, Zimmer AE, Ott EA.Thirty-five newborn foals were assigned to 1 of 3 groups and treated with 0.9% NaCl solution (saline; group 1; n = 12), oxytetracycline (44 mg/kg of body weight; group 2; n = 12), or 2-pyrrolidone (oxytetracycline vehicle; group 3; n = 11) in saline solution during the first 36 hours after birth. Serum biochemical analyses were performed on samples obtained from group-1 and group-2 foals before treatment and 24 and 96 hours after treatment. Lateral to medial radiographic views of the forelimbs were obtained before treatment and 24 and 96 hours after treatment in all foals. Metacarpophalangeal ...
Geyer H, Schulze J.The influence of dietary biotin in horses with brittle hoof horn and chipped hooves was investigated in a long-term study, which was performed over a period from one to six years. 97 horses received 5 mg of biotin per 100 to 150 kg of body weight, per os, daily; 11 horses were not supplemented with biotin and served as controls. The hooves of all horses were evaluated macroscopically every three to four months. Hoof horn specimens of the proximal wall were examined histologically and physically in 25 and 15 horses, respectively. The tensile strength of normal coronary horn was 60 N/mm2 or grea...
Jones DL.Medical records were reviewed for 11 horses with squamous cell carcinoma of the larynx and/or pharynx. The average age at presentation was 15.3 years. No breed or sex predilection was present. At presentation, 6 of 11 horses were dyspneic and 4 horses had inspiratory stridor. Endoscopy was performed in all cases and was more useful in demonstrating a mass in the laryngopharyngeal region than laryngeal or guttural pouch radiography. Surgical excision was attempted in 3 horses and in 1 horse alleviated clinical signs for 4 months. Ten horses were euthanatized and 1 horse died. Results of this st...
van der Velden MA, Klein WR.Seventy horses surgically treated for colic caused by disorders of the small intestine were included in a randomized blind trial to determine the effects of cisapride (0.1 mg/kg bw intramuscularly at 8-h intervals) on the post-operative restoration of gut motility. Cisapride appeared to reduce the incidence of post-operative ileus. It accelerated the restoration of bowel motility, reducing the period of post-operative intensive care. It is concluded that cisapride is an effective and useful drug in the post-operative treatment of horses after surgery of the small intestine.
Light GS, Hellyer PW.We investigated the influence of parasympathetic tone on the arrhythmogenic dose of dobutamine in horses premedicated with xylazine, anesthetized with guaifenesin and thiamylal, and maintained on halothane in oxygen. Six horses were used in 12 randomized trials. In each trial, after end-tidal halothane concentration was stabilized at 1.1% (1.25 times minimum alveolar concentration [MAC]) in oxygen, either saline solution (0.02 ml/kg of body weight) or atropine (0.04 mg/kg) was administered IV. Five minutes later, dobutamine infusion was started at dosage of 2.5 micrograms/kg/min, IV. The dobut...
Pilsworth RC, Holmes MA, Shepherd M.A fracture of the pelvis in a horse can be detected scintigraphically by probe point counting. However, the pelvis is covered by a large and variable muscle mass, and is close to the urinary bladder, both of which can introduce errors. This paper describes an improved technique which uses a larger set of sampling points and analyses the data with a small computer to construct a three dimensional graph of the gamma-ray output across the pelvis, thus helping to improve the interpretation of the data. The scintigraphic plot from a normal horse, three cases of fracture (confirmed by radiography, u...
Ruggles AJ, Ross MW, Freeman DE.Sixteen horses with suspected paranasal sinus disease had endoscopic examination of the paranasal sinuses with a 4.0 mm arthroscope either while standing and sedated (14 horses) or under general anesthesia (two horses). Endoscopic diagnosis included sinusitis (four horses), sinus cyst (three horses), hemorrhage (three horses), neoplasia (three horses), and tooth root abnormalities (two horses). No abnormalities were detected in one horse. Endoscopic findings concurred with the radiographic findings in 13 horses (81%). Samples of sinus contents for bacteriologic (eight horses) and histologic ex...
Baxter GM, Jackman BR, Eades SC, Tyler DE.Intra-abdominal adhesions were created by localized serosal trauma in 11 adult ponies at three locations on the small intestine. Six ponies received verapamil hydrochloride (0.2 mg/kg) subcutaneously every eight hours for three days, and five ponies received an equal volume of saline solution at the same intervals. The investigators were not informed which treatments the ponies received. Systolic, diastolic, and mean carotid arterial pressures and heart rates were measured six hours before surgery, and then 0.5, 1, 1.5, and 8 hours after the first treatment on each day for three days. One pony...
Golenz MR, Carlson GP, Madigan JE, Craychee T.Six normal foals between the ages of 2 and 7 days were used in this study to develop a technique for intraosseous infusion in equine neonates. A 14-gauge 1/2-inch needle was placed intraosseously in the right proximal medial one-third aspect of the radius and tibia of each foal. A maximum of 1 L of isotonic fluids was administered intraosseously at these sites. Radiographs were taken at the time of intraosseous needle placement, and at days 10, 30, and 60 following the procedure. The mean time for needle placement was 33 seconds for the tibia and 63 seconds for the radius. The mean fluid flow ...
Hoffman AM, Viel L, Staempfli HR, Muckle CA, Yager JA.One indication for referral of horses to veterinary hospitals is for diagnosis of the microbiologic cause of pneumonia, particularly when the initial treatment fails. Although endoscopic methods have long been available for microbiologic sample collection, accuracy of these methods under these conditions have not been studied in detail. We compared the bacteria isolated from samples obtained by bronchoalveolar lavage (BAL) with those obtained by protected catheter brush (PCB) from foals with unilateral pneumonia induced by inoculation with Klebsiella pneumoniae. As part of previously described...
Todhunter RJ, Freeman KP, Yeager AE, Lust G.This study assessed the effects of postoperative exercise and intra-articular polysulfated glycosaminoglycan (PSGAG) on the repair of osteochondral defects in the carpal joints of ponies. Eighteen ponies with normal carpi had osteochondral defects (mean dimensions 2.4 cm x 0.9 cm) created arthroscopically on the dorsal aspect of the distal articular surface of the radial carpal bone. The ponies were randomized (while balancing for age [range, 2 to 15 years; median, 5.0 years]) to two groups--nine ponies were exercised and nine were stall confined. Beginning at surgery, six ponies in each group...
Blikslager AT, Tate LP, Weinstock D.Effects of neodymium:yttrium aluminum garnet (Nd:YAG) laser irradiation on equine endometrium were evaluated in vitro and in six mares with endometrial cysts. The Nd:YAG laser was applied to six endometrial sites, in each of five uterine specimens, with power densities of 5659 to 33,954 J/cm2. Depth of tissue ablation was measured and graded on histologic sections of the tissue lesions. Power density had a significant effect on the depth of tissue ablation (p < .001). Grade 3 lesions (full-thickness ablation of the endometrium) were created with energy densities of 16,977 to 33,954 J/cm2. Six ...
Belknap JK, Baxter GM, Nickels FA.Medical records of 50 horses with extensor tendon lacerations affecting 53 limbs over 7 years (1982 to 1988) were reviewed to determine the clinical features and prognosis for athletic soundness after treatment. Mean and median ages were 4.8 and 3 years, respectively. Eighty-nine percent of the injuries involved the hind limbs, with approximately equal distribution between the right and left limbs. Hind limb lacerations involved the long digital extensor tendon (28 limbs), lateral digital extensor tendon (3 limbs), or both tendons (16 limbs). Forelimb lacerations involved the common digital ex...
Traub-Dargatz JL, Jones RL.A review of the literature describing clostridia-associated enterocolitis is presented. The bacteria, their toxins, and possible factors that interact to contribute to the pathogenesis of enterocolitis are described. Clinical signs associated with clostridia-associated enterocolitis, methods of diagnosis, treatments, and preventive strategies are discussed.
Wright IM, Douglas J.In recent years much attention has been paid to vascular studies of the navicular bone in health and disease; however, the relative importance of these studies has overshadowed biomechanical factors which may yet prove to be of importance. This paper outlines the pertinent anatomy, and discusses current concepts in the aetiology and pathogenesis of the disease. It describes the treatment regimens which are based on biomechanical considerations and compares the results of some currently employed techniques. All aspects of navicular disease remain controversial. This paper is not intended to rev...
Vivrette S, Cowgill LD, Pascoe J, Suter C, Becker T.Acute renal failure in a 4-day-old foal secondary to oxytetracycline toxicosis was treated by hemodialysis. Oxytetracycline had been administrered as treatment for forelimb flexor tendon contracture. Conservtive treatment with fluids, furosemide, and dopamine partially alleviated serum electrolyte concentration imbalances, but was ineffective in promoting diuresis or decreasing azotemia. Three hemodialysis treatments over 4 days were administered, after which the clinical appearance of the foal improved, and biochemical and electrolyte values returned to within reference ranges. The nephrotoxi...
Todhunter RJ, Altman NS, Kallfelz FA, Nersesian P, Lust G.Combined blood pool and delayed images produced by use of 99mTc-methylene diphosphonate (99mTcMDP) were evaluated as an objective measurement of the response of equine joints with osteochondral defects to postoperative exercise and intra-articularly administered polysulfated glycosaminoglycan (PSGAG). Osteochondral defects (approx 2.4 x 0.9 cm) were induced arthroscopically in the dorsodistal radial carpal bones of 18 ponies. These ponies were randomized (while balancing for age [range 2 to 15; median, 5.0; mean, 5.1 years]) to 2 treatment groups. Nine ponies were assigned to be exercised, and...
Moon PF, Suter CM.The caudal border of the last rib was used as a reliable point of orientation while performing paravertebral thoracolumbar anaesthesia (PTLA) on 10 horses undergoing standing flank laparotomy. The local anaesthetic in all horses was 2% lidocaine. The PTLA procedure was completed in 9.8 +/- 1.8 mins (mean +/- sd). Sedation was provided by a combination of intravenous morphine with xylazine or detomidine. Overall analgesia, provided by the combination of PTLA and sedation, was rated as excellent in 2 horses and good in 6 horses. In the remaining 2 horses, overall analgesia was rated as fair beca...
Todhunter RJ, Yeager AE, Freeman KP, Parente EJ, Lust G.Keratan sulfate (KS) is a glycosaminoglycan, distribution of which is confined mostly to hyaline cartilage. As such, it is a putative marker of hyaline cartilage catabolism. In experiment 1, a focal osteochondral defect was made arthroscopically in 1 radial carpal bone of 2 ponies, and in 2 other ponies, chymopapain was injected into the radiocarpal joint to induce cartilage catabolism. Sequential and concurrent plasma and synovial fluid concentrations of KS were measured, up to 13 months after induction of cartilage injury, to determine whether changes in KS concentrations reflected cartilage...
Matthews NS, Hartsfield SM, Sanders EA, Light GS, Walker MA.A 27-year-old horse was anesthetized 3 times a week for 4 weeks, to facilitate cobalt therapy of a squamous cell carcinoma in the left paranasal sinus. Limitations of facilities required transport of the anesthetized horse to and from the cobalt therapy room, therefore, injectable anesthesia was used. Initially, the horse was preanesthetized with xylazine (at 1.1 mg/kg IV) and butorphanol (0.04 mg/kg IV). After 3 anesthetic episodes, the xylazine dose was reduced to 0.4 mg/kg IV and the butorphanol was deleted from the regimen. Tiletamine-zolazepam (1.1 mg/kg IV) was used for induction and mai...
Léveillé R, Lindsay WA, Biller DS.Ultrasonography was a valuable diagnostic tool for examination of a ruptured peroneus tertius in a horse, because it allowed visualization of the extent of the injury and evaluation of healing prior to return of the horse to athletic activity.
Dyke TM, Hinchcliff KW.Ceftiohr sodium was evaluated as a therapy for respiratory
infections in horses. This cephalosporin antimicrobial was
administered intramuscularly every 24 h and at a dose of 2.2
mglkg (1.0 mgllb) of body weight. The efficacy of ceftiofur
sodium was compared with that of a positive control drug,
ampicillin sodium (recommended dose of 6.6 mg/kg [3 mg/lb],
given every 12 h). Both treatments were continued for 48 h
after clinical symptoms were no longer evident (maximum of
10 days). Fifty-five (55) horses with naturally acquired
respiratory infections were included in the study; 28 were
...
Parente EJ, Richardson DW, Spencer P.Medical records of 57 horses admitted between 1980 and 1991 because of basal sesamoidean fractures were evaluated. Radiographic measurements of fragment size and fracture characteristics were recorded to determine their relationship to outcome. A successful outcome was assessed on the basis of the ability to return to racing, ability to race more than one time, and ability to finish first, second, or third. Any change in racing class also was assessed. There was a significant (P < 0.001) overrepresentation of Thoroughbreds, compared with other breeds in the hospital population. Fractures of...
Hoff TK, Hood DM, Wagner IP.To evaluate the clinical efficacy of topically administered glyceryl trinitrate (GTN) for inducing digital submural vasodilation in clinically normal horses. Methods: 7 adult horses without foot abnormalities. Methods: A concurrent-control crossover design was used to determine whether topical application of GTN ointment for prevention or treatment of laminitis would result in a detectable increase in digital perfusion. Heat-acclimated horses instumented for detection of wall surface temperature (HWST), mean systemic pressure, and heart rate were used. Horses were exposed to cold to induce dig...
Berndtson WE.Data from testes of 16, 2- to 3-yr-old stallions and 34 yearling beef bulls were utilized in a components of variance approach to calculate the number of observations required per testis and(or) the number of animals required per treatment group to provide experiments of known sensitivity and precision, where treatment was to be assessed by one of several endpoints. The latter included paired testes weight, seminiferous tubular diameter, the number of germ cells per seminiferous tubular cross-section, or the number of elongated spermatids per gram of testicular parenchyma or per testis. For al...
Lloyd KC, Kelly AB, Dunlop CI.A foal born 3 weeks prematurely was treated for respiratory distress, using a combination of oxygen therapy and mechanical ventilatory assistance. Clinical response and arterial blood gas tensions were monitored regularly. Continuous positive-airway pressure and intermittent positive-pressure ventilation administered via a nasotracheal tube were effective in improving arterial oxygenation and ventilatory function.
McBeath DG, Best JM, Preston NK, Duncan JL.Examination of faecal egg counts in horses and ponies has shown that after treatment with fenbendazole at dose levels of 7.5, 45 and 60 mg/kg, faeces remained free from strongyle eggs for periods of 6 to 18 weeks. The significance of these results is discussed in relation to routine anthelmintic treatment of horses. In particular, the activity of fenbendazole against mucosal stages of strongyle parasites allows for treatment to be recommended at less frequent intervals than when using other anthelmintics.
Beech J, Fletcher JE, Tripolitis L, Lindborg S, Dawso T.The contractile activity, the threshold for calcium-induced calcium release in fractions of sarcoplasmic reticulum and the potassium concentration were determined in preparations of semimembranosus muscle from normal quarter horses and quarter horses with hyperkalaemic periodic paralysis before and after they were treated with phenytoin. Before the treatment there was no difference in caffeine contracture or electrically elicited twitch response between the two groups. For one week after the treatment, the time to peak tension of caffeine contractures was significantly (P < 0.005) reduced i...
Stähli P, Grest P, Favrot C, Feige K.A 10-year-old Haflinger gelding was presented with severe generalized chronic dermatitis characterized by scales, crusts and widespread alopecia with a partially diffuse and partially circumscribed pattern. Pemphigus foliaceus was diagnosed based on history, clinical signs and histological examination of skin biopsies. Typical histological findings were subcorneal pustules with accumulations of intact neutrophil granulocytes and acantholytic keratinocytes. The gelding was treated with glucocorticoids and gold salts. The skin lesions resolved completely after 8 weeks of treatment. No recurrence...
Meagher DT, Latimer FG, Sutter WW, Saville WJ.OBJECTIVE-To determine clinical findings and outcome in horses treated by means of a balloon constant rate infusion system. DESIGN-Retrospective case series. ANIMALS-23 horses. PROCEDURES-Medical records of horses examined at The Ohio State University veterinary teaching hospital from 2002 to 2005 that had septic arthritis, septic tenosynovitis, or penetration of a synovial structure and in which treatment involved a balloon constant rate infusion system were searched. Information pertaining to signalment, history, physical examination findings, clinicopathologic data, treatment, and duration ...
Willsallen H, Yang PJ, Jacobs KA.This case report describes the accidental intramuscular administration of 20 mL Gudair® vaccine to a 7-year-old Standardbred mare and successful treatment of the resulting inflammatory reaction by radical surgical resection.
Berghuis GA, Wesselink HG.Twenty nine mares with retained fetal membranes were treated IV with an oxytocine infusion. Within two hours the placenta released in 24 mares (83%). Twenty six (90%) mares got pregnant during the same season.
McColl HP, Orchard VA.Sir,—A series of happy coincidences (serendipity?) has led us to a simple treatment which seems to have successfully alleviated symptoms of “rye-grass staggers” in a horse, a calf and two badly affected sheep. Although primarily engaged in a search for the causative agent(s) of rye-grass staggers, casual conversations with people having long experience of this disorder revealed many interesting observations. One of these was a racing-stable remedy for rye-grass staggers, which was the administration of “a couple of handfulls” of Epsom salts in a bran mash, with as much puha (Sonchus ...
Kannegieter NJ, Ecke P.A Thoroughbred gelding was referred for treatment of a parotid duct fistula. This had developed after the referring veterinarian had excised a portion of the duct, and ligated the proximal end, as a means of treating a recurring sialocoele. This report describes the successful surgical reconstruction of the excised 15 cm portion of the parotid duct using an interposition polytetrafluoroethylene tube graft.
Collard XR, Danse EM, Rombouts JJ.The treatment of acute complete (grade III) tears of the lateral ligaments of the ankle has generated much controversy in the medical literature. Functional treatment has become the standard treatment as it has been shown that there is no significant difference in long term results whatever the treatment (operative repair and cast, cast alone, or early controlled mobilization). Functional treatment includes only a short period of protection by tape bandage or brace and allows early weight-bearing. Major trauma with avulsion of bone and severe ligamentous damage on both medial and lateral sides...
Schauvliege S, Van den Eede A, Duchateau L, Pille F, Vlaminck L, Gasthuys F.To investigate the influence of calcium chloride (CaCl(2)) on the cardio-respiratory effects of enoximone in isoflurane anaesthetized ponies. Methods: Prospective consecutive experimental trial. Animals Six healthy ponies, weighing 287 +/- 55 kg were included in this study. Methods: After sedation (romifidine, 80 microg kg(-1)), anaesthesia was induced with midazolam (0.06 mg kg(-1)) and ketamine (2.2 mg kg(-1)) and maintained with isoflurane in oxygen. The ponies' lungs were ventilated to maintain normocapnia. After 90 minutes, a bolus of enoximone (0.5 mg kg(-1)) was administered, followed b...
Bohn A, Papageorges M, Grant BD.Ultrasonography and radiography were used to diagnose bicipital tenosynovitis and humeral osteitis in a horse with a history of lameness of 7 weeks' duration. Surgical exploration confirmed the diagnosis.
Ayala I, Rodríguez MJ, Aguirre C, Buendía AJ, Belda E, Laredo FG.This report describes a case of postanesthetic brachial triceps myonecrosis affecting only the left forelimb of a horse. A fatal unilateral postanesthetic myonecrosis has not been previously reported in the horse. This article describes the factors in the horse's history, the anesthetic protocol, and the treatment that may have led to this condition. Ce rapport décrit un cas de myonécrose postanesthésique du triceps brachial affectant seulement la patte avant gauche. Une myonécrose postanesthésique unilatérale mortelle n’avait pas encore été signalée chez le cheval. Le présent art...
Held JP, Blackford JT.Three cases of vaginal perforation after coitus are discussed. The most consistent clinical sign is a small amount of blood escaping from the vulvar lips immediately after breeding. Secondary infection and posttraumatic swelling may cause abdominal pain due to rectal impaction. Treatment with high levels of an appropriate antibiotic is important to reduce the risk of a severe infectious peritonitis. The use of artificial insemination or a breeding roll to prevent full intromission is recommended.
Allen WE, Clarke AR.Plasma concentrations of sodium benzylpenicillin following intrauterine infusion were increased by reducing the volume of solution and expelling air from the vagina after infusion. Instillation of 10 per cent Lugol's iodine solution into the uterus before penicillin infusion further increased the absorption rate, although peak plasma levels of penicillin were less than half those which resulted from intramuscular injection of the same dose.
Mageed M, Dyab S, Swagemakers JH, Gerlach K.The impact of different acquisition times (AqT) and technetium-99 m-labeled ( Tc) diphosphonates on the image quality of bone scintigraphy is poorly documented in horses. The aim of this prospective experimental study was to evaluate the impact of varying Tc-disphosphonates and AqT on semiquantitative and qualitative image parameters of bone scintigraphy in horses. Twenty-four horses undergoing bone scintigraphy were divided equally and randomly into methylene- (MDP), hydroxymethylene- (HDP), and dicarboxypropane diphosphonate (DPD) groups. Lateral scintigraphic images of the antebrachium we...
Riggott JM, Quarmby WB.A surgically excised tumour from the thoracic wall of a hunter mare was diagnosed as a fibrosarcoma on histological examination. Its recurrence necessitated further surgery 6 weeks later. Because of the invasive nature of the lesion a prolonged course of chemotherapy was administered postoperatively. The tumour did not recur a second time.
Bergman HJ, de Kruif A.In this last article the veterinary supervision of problem mares at the stud is reviewed. Treatment possibilities are evaluated. The usefulness of treatment with progestagens in order to sustain pregnancy or to prevent embryonic death is discussed.
Schneider RK, Andrea R, Barnes HG.An open, contaminated, comminuted fracture of the radius of a 500-kg adult horse was diagnosed. Antibiotic-impregnated polymethyl methacrylate implants were placed into the fracture site to help eliminate infection from the limb. Later in the course of treatment, lag screws were placed across the fracture to generate compression and healing. The fracture healed, and the horse was released to its owners. The implants were not removed, and only a mild lameness existed 90 days later.
Jalim SL, McKinnon AO, Russell TM.A Monteggia fracture is a humero-radial luxation combined with a fracture of the ulna. It is a rare injury, infrequently reported in the horse. This case report describes the surgical repair of such a fracture in a 4-month-old filly.
Dixon PM, McGorum BC, Long KJ, Else RW.An outdoor pony which developed severe respiratory distress in February was shown to have acute interstitial pulmonary disease (alveolitis), which was characterised by a massive exudation of eosinophil rich fluid into the airways. While antibiotic treatment before referral was ineffective, the condition rapidly responded to corticosteroid therapy. No evidence of lungworm was present and it appears that this interstitial pulmonary disease had an immune-mediated aetiology. Bronchoalveolar lavage cytology was of great value in the diagnosis and monitoring of this case.
Rabbogliatti V, De Zani D, Zani DD, Di Cesare F, Brioschi FA, Gioeni D, Crivellari B, Ravasio G.To compare the peribulbar injectate distribution and probability of regional anaesthesia of four peribulbar anaesthetic techniques in equine cadavers. Methods: Prospective experimental cadaver study. Methods: A total of 12 isolated equine cadaver heads and 24 eyes. Methods: The 24 orbits underwent one of four injection techniques (six orbits each) with a mixture (1:4) of contrast medium and saline (CM): 20 mL ventrolateral peribulbar injection (V-20), 20 mL dorsolateral peribulbar injection (D-20), combined ventrolateral and dorsolateral peribulbar injections 10 mL each (VD-20) or 20 mL each (...
Bohanon TC, Gabel AA.A heat-vulcanized silicone implant was used for cosmetic repair of a facial deformity in a horse. The deformity had resulted from fracture of the frontal bone into the frontal sinus 6 months earlier. Normal facial contour was restored by suturing the sculpted implant to the periosteum over the defect. Results 1 year after surgery were excellent.
Swor TM, Watkins JR, Bahr A, Epstein KL, Honnas CM.Previous olecranon fracture reports contain a small proportion of type 5 fractures, mostly treated with conservative therapy. Objective: To evaluate the clinical details and outcome of type 5 olecranon fractures in a large group of horses treated by tension band plate fixation and to compare results with other treatment methods. Methods: Medical records of 97 cases, including 32 (33%) classified as type 5, were reviewed. Subject details, history, radiographic findings, treatment and follow-up results (2-146 months post operatively) were recorded. Results: Treatment included open reduction and ...
Wright IM, Montesso F, Kidd LJ.This paper describes the clinical and radiological features, surgical techniques used and results obtained in 6 horses with fractures of the tibial tuberosity. The horses were presented between 24 h and 8 weeks following injury. In all 6 cases, the fragments were displaced proximocranially and in 2 of these, there was comminution. Four were treated by open reduction and internal fixation using an AO/ASIF narrow dynamic compression plate and in 2 cases the fragments were removed. All horses returned to full athletic function and remained sound in follow-up times of 17-36 months. Implant removal...
Garner C, Stephen C, Pant SD, Ghorashi SA.Streptococcus equi subsp. zooepidemicus (S. zooepidemicus) is one of the causative agents of equine endometritis. In this study, a panel of different bacterial species, and colonies derived from bacteriological cultures of 38 clinical samples, were subjected to Loop-Mediated Isothermal Amplification (LAMP) assay and PCR, followed by high-resolution melt (HRM) curve analysis. All clinical samples were genotyped into three distinct groups based on HRM curve analysis. Differences in melting curve profiles were a reflection of DNA variation in sorD gene which was confirmed by DNA sequencing. A mat...
Booth TM, Butson RJ, Clegg PD, Schramme MC, Smith RK.Gentamicin-impregnated polymethylmethacrylate beads were used to treat infective arthritis in the small tarsal joints of 11 severely lame horses. Under general anaesthesia, between five and 10 beads were placed into a 7 to 8 mm tract drilled across the affected joint and, in all except one horse, they were left in place for 14 days. Two of the horses were euthanased for reasons other than persistent tarsal joint sepsis, but the other nine survived and seven of them returned to their previous level of athletic performance.
Frei S, Geyer H, Hoey S, Fuerst AE, Bischofberger AS.To determine scapular cortex thickness, distal scapular bone density and describe the exact suprascapular nerve course to evaluate the best plate position for the fixation of supraglenoid tubercle fractures in horses. Methods: Twelve equine cadaveric shoulders were examined with computed tomography. Computed tomography morphometry and density measurements (Hounsfield units [HU]) of the scapula were recorded. Statistical comparisons were made between the cranial and caudal aspects of the scapula. Dissection of each shoulder was performed and the suprascapular nerve course was described morphome...
