Topic:Case Reports
Case reports in equine medicine provide detailed accounts of individual horses' clinical presentations, diagnostic processes, treatments, and outcomes. These reports are valuable for documenting rare conditions, novel treatment approaches, or unique clinical insights that may not be captured in larger studies. By focusing on individual cases, these reports contribute to the broader understanding of equine health and disease management. They often include comprehensive information on the horse's history, clinical findings, diagnostic tests, therapeutic interventions, and follow-up evaluations. This page assembles peer-reviewed case reports and scholarly articles that explore diverse aspects of equine health, offering insights into specific medical scenarios and their implications for veterinary practice.
A study of the effects of lasering on chronic bowed tendons at Wheatley Hall Farm Limited, Canada, January, 1983. Chronic bowed tendons of horses have been lasered with an infrared 904-nm laser at Wheatley Hall Farm Limited since 1980. A sample of 42 single injury/single treatment standardbreds which were racing within 120 days of laser treatment and met certain criteria, were evaluated for final race times, last quarter race times, and class changes. Results indicate that a significant percent of the standardbreds raced with similar or improved times and classes. Lasering bowed tendons presents a safe and less expensive alternative to traditional treatment methods which often requires a year layoff for t...
Review of 30 cases of peritonitis in the horse. Thirty cases of peritonitis, in which the diagnosis was based on a peritoneal fluid white blood cell count in excess of 10 x 10(9)/litre, are described. Colic, ileus, pyrexia, weight loss and diarrhoea were common presenting signs. Treatments included intravenous fluids, anti-inflammatory analgesics, broad spectrum antibiotics and anthelmintics. Duration of treatment was determined by the clinical condition of the horse and sequential analyses of the peritoneal fluid and the haemogram. In the majority of cases the primary cause of peritonitis was not accurately determined, but 21 horses (70 pe...
Neuroepithelial tumor of the optic nerve in a horse. A nine-year-old horse was presented with severe exophthalmos of the right eye and a large mass in the vitreal cavity. The affected globe was enucleated and two months following surgery the horse was euthanized because of spread of the tumor into the calvarium producing compression of the brain stem and neurologic signs. Examination of tumor tissue by light and electron microscopic examination showed a mixed neoplasm of primitive neuroepithelium.
Clinical aspects of lymphosarcoma in the horse: a clinical report of 16 cases. This paper describes the clinical and laboratory findings in 16 horses suffering from lymphosarcoma and the autopsy results in 13 of these cases which were examined at the Large Animal Medicine Clinic, State University of Utrecht, from 1969 to 1981. The cases were classified into four groups, designated multicentric, alimentary, thymic and cutaneous forms, according to the situation of the tumours.
Navicular disease in the horse. The subchondral bone pressure. The subchondral bone pressure in the navicular bone of horses with navicular disease is compared with corresponding pressures in normal horses. An increased intraosseous pressure and a lengthened pressure drop time was demonstrated in patients with navicular disease, which indicates the existence of a venous stasis. Compared with similar investigations in humans with arthrosis it is concluded that navicular disease is a condition resembling arthrosis. The classical clinical symptoms are explained as an expression of resting pains. Treatments are suggested which theoretically can render the pat...
Methods for the treatment of twin pregnancy in the mare. Within a group of 130 mares which, in the event, carried twin pregnancies, 29 (22.3 per cent) produced their twins following diagnosis of a single palpable follicle at service and a single pregnancy 42 days later. The whole group of 130 twin-pregnant mares gave birth to only 17 live foals (13 per cent). Breeding results for the following season were available for 102 of these mares, when 38 (37 per cent) produced live foals. Thus over the two seasons an average 23 per cent of this group produced live foals. In a second group, comprising 70 mares, twin pregnancy had been diagnosed in all of the...
Fractures of the distal phalanx in horses. 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.
Joint mice in the fetlock joint–osteochondritis dissecans. Joint mice in the horse is a wellknown condition, but during the last years diagnosed with increasing frequency. Ethiology and prognosis thus become of major interest. 53 cases of mice in the fetlock are examined and divided in 3 groups on the basis of localization and appearance. On one group characterised by a localization in the plantar aspect of the joint and clearly separated from the tuberosites of the first phalanx histological investigations were carried out resulting in the statement that the mice can be the result of osteochondrosis. Surgical intervention in cases with clinical sympt...
Microsporum equinum in North America. Microsporum equinum was isolated in Ontario, Canada, from five human and two equine cases of ringworm infection. This dermatophyte was previously recovered from North American horses on several occasions, but was considered to be M. canis. We regard M. equinum as distinct from M. canis. It can be differentiated from M. canis by the smaller size of its macroconidia, its failure to perforate hair in vitro, its poor growth and sporulation on bromocresol purple casein dextrose agar, and its incompatibility with Nannizzia otae, the telemorph of M. canis.
Foetal monstrosity in a thoroughbred mare resembling schistosomus reflexus. This study discusses a case of foetal abnormality resembling schistosomus reflexus in a thoroughbred mare, noting its similarity to documented instances in bovines and pointing towards the need for more […]
Atrial fibrillation in horses: factors associated with response to quinidine sulfate in 77 clinical cases. Seventy-seven horses with atrial fibrillation (AF) were treated orally with quinidine sulfate (QS) at the University of Pennsylvania, School of Veterinary Medicine, Thirty-seven horses (48%) had adverse reactions to QS, the most common of which were nasal mucosal edema, anorexia, colic, and diarrhea. The mean highest daily QS dose was slightly greater in horses showing toxicity (P less than 0.1) and their conversion rate was less (P less than 0.05). A schedule of gradually increasing QS dose was time consuming, costly and not associated with fewer adverse reactions. Horses were compared by the...
Multiple congenital heart anomalies in five Arabian foals. Five Arabian or half-Arabian foals with suspected multiple cardiac anomalies were examined. Various combinations of clinical examination, electrocardiography, angiocardiography, cardiac catheterization, blood gas analysis, radiography, and echocardiography resulted in clinical data that allowed accurate antemortem diagnoses to be made. In 4 cases, the clinical diagnosis was substantiated by postmortem findings. The confirmed diagnoses were: pseudotruncus arteriosus, a combination of patent ductus arteriosus, pulmonic stenosis, and tricuspid stenosis, pentalogy of Fallot, and tricuspid atresia....
