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.
Diaphyseal angular deformities in three foals. Angular limb deformities in 3 foals were found to originate in the diaphyseal region of the 3rd metacarpal (2) and metatarsal (1) bones. In each case, treatment consisted of wedge ostectomy followed by compression plating. Two foals survived for useful performance; the 3rd was euthanatized because of ischemia of the operated limb. The condition appeared to resemble a similar syndrome in man involving tibial curvature.
Wedge osteotomy as a treatment for angular deformity of the fetlock in horses. Five young horses with fetlock varus deformities of 8 degrees or greater were treated by means of wedge osteotomy of the distal end of the 3rd metacarpal or metatarsal bone. Three patients were admitted to the Western College of Veterinary Medicine and 2 to Colorado State University. Their selection as surgical patients was based on the following criteria: (1) an angular limb deformity of 8 degrees or greater, (2) patient older than 120 days, (3) no evidence of lameness, and (4) no evidence of degenerative joint disease. The surgery was successful in all cases.
Uroperitoneum in the foal. The case records of 22 foals with uroperitoneum were reviewed. The most common cause was a defect in the urinary bladder. A sex predilection for males was apparent. Clinical signs were tachycardia, tachypnea, and abdominal distention. The history pertaining to micturition was variable. Hyponatremia, hypochloremia, and hyperkalemia were marked. A reliable means of diagnosis was considered to be the demonstration of a wide disparity in serum and peritoneal fluid creatinine values. Surgical repair was successful in 11 of 18 cases, although surgical and anesthetic complications were common. Some o...
[A pony with “false” colic]. Report on the case of a pony with colic submitted a to the department of internal medicine. However, the animal was found to be affected with dilatation of the oesophagus which had given rise to acute pleurisy resulting from rupture of the wall of the oesophagus. The diagnosis was established after death.
Relapsing idiopathic thrombocytopenia in a horse. TEIROMBOCYTOPENIA can be caused by failure of production or increased destruction of platelets, resulting in a bleeding diathesis, characterised by mucosal petechiac and haemorrhage into various organs. In humans, some drugs (cg, phenylbutazone and chloramphenicol) cause idiosyncratic marrow suppression and subsequent thrombocytopenia. Bone marrow suppression is also well documented in humans and small animals receiving cytotoxic drugs (Calabresi 1979; MacEwen 1980). Decreased megakaryocytic proliferation is rarely recognised in large animals. The most prevalent causes of thrombocytopenia are ...
[Progressive course of spinal cord tumors]. The main clinical varieties of spinal cord and equine tail tumors are reviewed. Of 221 cases, the progressive course of the disease was recorded in 76,9%, slow-progressive course was observed in 68,1% and rapid-progressive in 8,8% of cases. It is stressed that in the presence of the progressive course of the disease there may occur different manifestations of the tumorous process of the spinal cord, the examination of which makes it possible to improve the diagnosis, particularly in the early stage of the spinal oncological process.
Cutaneous onchocerciasis in the horse: five cases in southwestern british columbia. Five horses were presented because of a dermatitis of the forehead. Unlike previous reports, ventral midline dermatitis was not the major problem, and was present in only two of five cases. All five horses responded to levamisole therapy at a daily dosage of 5.5 g for one week. Owners were cautioned that repeat therapy may be necessary.
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.
