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.
Morphology and pathology of the equine umbilical cord. A brief description is given of the morphology of the umbilical cord and some variations encountered. In 95% of normal Thoroughbred foals the cord measures less than 84 cm. Factors which govern cord length are not known. Seven pathological conditions involving the umbilical cord are described. Increased length is the most common abnormality and predisposes to three potentially lethal conditions, strangulation of the cord around the fetus, excessive torsion, and allantochorionic necrosis at the cervical pole.
An intersex (male pseudohermaphrodite) horse with 64XX/XXY mosaicism. The clinical, pathological and chromosomal findings in a male pseudohermaphrodite horse are reported. This animal appeared to be a female but showed strong male sexual behaviour. A small penis emerged from a rudimentary vagina. Two small testes were present in the abdomen and undifferentiated seminiferous tubules contained only supporting cells. No uterus was found. Culture of peripheral blood leucocytes revealed a 64XX/65XXY mosaicism.
Collection of bone grafts from the tuber coxae of the horse. Autogenous bone grafts were obtained from the tuber coxae of 9 horses. The method used involved an oblique incision to expose the lateral aspect of the tuber coxae. The periosteum was incised and reflected in order to make a 5- by 2.5-cm opening in the lateral cortex for graft retrieval. The method provided good visualization, ample grafting material, and freedom from postsurgical complications.
Lag screw fixation of avulsion fractures of the second phalanx in the horse. Avulsion fractures of the posteromedial eminence of the 2nd phalanx were repaired, using an ASIF cortex screw in 3 reining Quarter Horses. Within 9 and 11 months, respectively, 2 horses were sound and back in competition as reining horses. The other horse was sound for pleasure class showing at 7 months after surgery.
The effect of excess dietary iodine on pregnant mares and foals. On a thoroughbred stud four foals were born with greatly enlarged thyroids and leg weakness. Two foals died within 18 hours of birth, the others subsequently recovered. An enlarged thyroid was also evident in one of the resident mares. The thyroids from the dead foals were hyperplastic. Feed analyses showed that the mares had an iodine intake of about 83 mg daily, 8-8 ppm of the dietary dry matter, due almost entirely to the high iodine content of a proprietary compound horse nut which had been fed at the daily rate of 12 lb per head. It was concluded from the histology of the thyroids, the hi...
Equine granulosa cell tumors. Unilateral ovariectomy was performed on 3 mares affected with granulosa cell tumors. Tumor fluid in each mare was found to contain estrogen, testosterone, and progesterone. In 2 mares, preoperative blood plasma concentrations of these hormones were comparable to those of a series of clinically normal mares. The other mare, which had a history of aggressive, masculine behavior, had higher testosterone content in the tumor fluid and in the preoperative blood sample. After surgical removal of the tumors, each mare developed follicles and ovulated with the remaining ovary. Each was eventually bred...
Auto-immune hemolytic anemia in two horses. Two cases of Auto-immune hemolytic anemia (AHA) in the horse are described. The pathogenesis of AHA in man is related to the findings in the horses. Besides from routine hematological and biochemical investigations specific data were obtained from the erythrocyte osmotic fragility test, the Coombs test, the serum haptoglobulin level and the cold agglutinin test. The first patient, a six month old Dutch standardbred colt, probably suffered from an acute attack of cold-induced hemoglobinuria with severe anemia and acronecrosis of the tops of both ears and of several parts of the skin that had be...
A case of equine laryngospasm. This research presents a unique case of laryngospasm in a horse, a condition that is often observed in cats and other domestic animals, but rarely reported in horses. Traditional methodologies […]
The treatment of horses with chronic back pain by resecting the summits of the impinging dorsal spinous processes. This paper describes the surgical treatment of 14 horses exhibiting chronic back pain attributed to impaction and overriding of the dorsal spines in the thoracolumbar region. The technique involved the resection of the summits of one or more dorsal spines following midline division of the supraspinous ligament. All the horses returned to full work after a convalescent period of at least four months, and 12 of them showed considerable improvement in their form and performance. A post-surgical complication encountered in one case was the development of new bone on the edge of a resected spine. T...
Isolation of equine herpesvirus type 1 from a horse with an acute paralytic disease. A Standardbred mare became paralyzed shortly after showing signs of an upper respiratory infection. The mare was euthanized and equine herpesvirus type 1 was isolated from the brain and spinal cord.
The indications for equine laparotomy–an analysis of 140 cases. The indications for laparotomy in 140 horses are analysed, with particular emphasis on the operative or autopsy findings in 82 cases of colic. In cases of exploratory laparotomy, the overall recovery rate was only 28 per cent but 48 of the 82 animals were considered to have inoperable lesions. The recovery rate and causes of death for each indication are briefly reviewed.
