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.
Field outbreaks of leukoencephalomalacia in horses consuming maize infected by Fusarium verticillioides (= F. moniliforme) in South Africa. Four outbreaks of leukoencephalomalacia in horses in widely separated areas in South Africa are reported. The clinical signs and pathological lesions observed in each outbreak are briefly described. Mouldy home-grown maize from which Fusarium verticillioides (Sacc.) Nirenberg (= F. moniliforme Sheldon) was isolated in every instance, was involved in the outbreaks. Clinical signs and pathological lesions were identical to those seen in experimentally produced cases of F. verticillioides poisoning in horses.
[An analysis of stallion fertility based on the number of matings per heat]. The fertility problems were studied in the herd of the English Thoroughbred horse on the Napajedla stud farm. Breeding records for the period from 1880 to 1972 were used as the starting data. The survey comprised 32 stallions. The relationship between fertility and the number of matings was calculated by the chi 2 quantity. The calculated values are highly variable. However, it is generally seen in most of the stallions that the number of matings per heat (i. e. one or several matings) had no significant influence on the pregnancy of mares and on the fertility values of the stallions. A higher...
Obstruction of the small colon by intramural haematoma in three horses. Three cases of intramural haematoma of the small colon of horses are presented. In all cases the haematoma obstructed the lumen and caused an accumulation of faeces and gas. The horses were in shock and had acute abdominal pain. Exploratory abdominal surgery revealed the haematomas and showed them to be associated with chronic infection and terminal rupture in one animal which was subsequently killed, and an iatrogenic perforation of the terminal small colon in another which survived after intestinal resection. In the remaining horse, which died without recovering after intestinal resection, n...
Carpal bone lesions associated with angular limb deformities in foals. Six foals with angular limb deformities present at birth or shortly after were examined. The limb deformities were caused by abnormalities of the carpal bones and included hypoplasia and osteochondritis dissecans. The 3rd carpal bone was affected most frequently.
Tracheal reconstruction by resection and end-to-end anastomosis in the horse. A surgical technique for resection of a portion of the trachea followed by end-to-end anastomosis was developed on 4 clinically normal horses. The trachea healed without complications in 3 of the horses in which 3 tracheal cartilages were removed. Five tracheal cartilages were removed from the 4th horse. It had to be euthanatized because of excessive suture line tension and wound disruption, which occurred during recovery from anesthesia. Suture line tension was measured on 3 other clinically normal horses positioned in dorsal recumbency immediately after euthanasia after 3 and 5 tracheal cart...
Bacillus piliformis infection (Tyzzer’s disease) in foals in northwestern United States: a retrospective study of 21 cases. From Jan 1, 1967 through June 1980, 21 cases of Bacillus piliformis infection (Tyzzer's disease) in foals were diagnosed at the Washington Animal Disease Diagnostic Laboratory. Affected foals died between 7 and 35 days of age. Of 4 Arabian foals with the disease, 2 also had combined immunodeficiency.
Poisoning in animals due to oral application of iron. With description of a case in a horse. Peroral application of iron salts in various types of anemia was previously considered atoxic. The increased use of iron has, however, led to an increasing number of poisoning in children, taking iron tablets for candy. There have only been reported a few number of spontaneous intoxications in animals, but experimentally it has been possible to produce fatal intoxications in various kinds of animal species. The clinical findings are quite similar in the various animals, starting with vomiting, bloody diarrhoea and metabolic acidosis. If the intoxication is severe, shock and coma may develop, a...
Intestinal infarction associated with mesenteric vascular thrombotic disease in the horse. Intestinal infarction associated with cranial mesenteric artery thrombosis, without strangulation obstruction of the intestine, was studied in 18 horses. Findings normally of value in evaluating horses with acute abdominal pain (heart rate, rectal palpation findings, gastric reflux) or classification of the degree of pain were not helpful in diagnosing the problem. Similarly, packed cell volume, plasma total protein, circulating white blood cell count, peritoneal white blood cell count, and peritoneal fluid total protein were not of value in predicting severity of the intestinal damage, locati...
Evaluation of a surgical technique for repair of equine accessory carpal bone fractures. In 9 horses, osteotomies were performed to simulate accessory carpal bone fractures. Screw fixation, aided by a large C-clamp, was performed on 6 of the 9 horses. Three were treated conservatively, as controls, with fractures not repaired; they remained clinically lame throughout the 6-month study. Fibrocartilaginous nonunion developed in each of the 3 controls. At 150 days, the principals were free of lameness, with evidence of bony union. The results of clinical, radiographic, and pathologic evaluations showed surgical repair to be superior to prolonged rest in treating equine accessory carp...
Metabolic abnormalities associated with rupture of the urinary bladder in neonatal foals. Rupture of the urinary bladder was diagnosed in 4 neonatal male foals. Marked hyponatremia, hypochloremia, and hyperkalemia developed in all 4 cases, and the electrolyte abnormalities were considered to be of potential diagnostic value. Blood urea nitrogen concentration was normal or only slightly higher than normal in 3 of 4 cases and therefore was not a reliable diagnostic test.
The value of zinc protoporphyrin in equine lead poisoning: a case report. A diagnosis of lead poisoning in a foal was established based on clinical signs and the presence of an elevation in the concentration of blood lead (40 microgram/dl). Additionally, ZPP was determined in whole blood and found to be significantly elevated compared to 10 normal horses not exposed to lead (634 vs 73 microgram/dl). An elevation in ZPP in man has been found to be a sensitive biochemical indicator of lead toxicity even before overt clinical signs are present. This report suggests that ZPP may be a useful screening test for evaluating biological toxicity due to lead in horses and poss...
Torsion of the spermatic cord in a horse. A 360-degree torsion of the left spermatic cord was diagnosed in a 2 1/2-year-old Quarter Horse colt. Clinical signs included abdominal discomfort, with slight elevations in heart and respiratory rates. The scrotum on the left side was moist and edematous. The left testicle was enlarged, firm, and retracted slightly toward the abdominal cavity. The colt resented palpation of the testicle. On rectal palpation, the left vaginal ring and the structures passing through the ring were edematous and painful to pressure. Surgical correction was achieved by emasculation. The tail of the epididymis and ...
A complication of cryptorchid castration in three horses. During an 8-month period, 3 horses were examined because of incomplete cryptorchid castration. Each horse had had surgery to remove 1 retained testis. In each case, the attending veterinarian believed castration had been adequately completed. History, rectal examination findings, and in 2 cases, high serum testosterone concentration were factors that led to the decision to do exploratory surgery on each horse. In each case, initial surgery had resulted in surgical removal of the tail of the epididymis, which was mistaken for testicular tissue.
[An uncommon cause of colic (author’s transl)]. A rare case of colic in an eleven-year-old New Forrest mare is reported. As treatment was ineffective, the animal had to be slaughtered. Post mortem examination showed that the colic was due to bilateral haemorrhagic corpus luteum, from which blood (appr. 20 liter) entered the abdominal cavity.
