Topic:Diagnosis
Diagnosis in horses involves the systematic identification of diseases and conditions affecting equine health. This process relies on a combination of clinical evaluations, laboratory tests, imaging techniques, and other diagnostic tools to assess the health status of horses. Veterinarians utilize these methods to identify symptoms, determine the underlying causes of health issues, and formulate appropriate treatment plans. Diagnostic procedures in equine medicine can include blood tests, ultrasound, radiography, endoscopy, and more specialized tests such as genetic screening or advanced imaging modalities like MRI and CT scans. This page aggregates peer-reviewed research studies and scholarly articles that explore various diagnostic techniques, their applications, and advancements in the field of equine veterinary medicine.
Intestinal obstruction in the horse. Physical signs and blood chemistry. Physical signs and blood changes were studied in horses with artificially produced obstructions of the duodenum and the small colon and simulated volvulus of the ileum. Horses with obstruction of the duodenum had the most violent physical signs and the shortest survival time. Blood changes were an initial rise in pH followed by acidosis, hyperkalemia and a decrease in HCO3 minus, Na+ and C1 minus. Obstruction of the small colon resulted in mild physical signs. The blood parameters recorded were normal. Simulated volvulus resulted in continuous colic. Blood changes were acidosis and hyperkalemi...
XO-gonadal dysgenesis in the mare (report of two cases). TWo cases of XO-gonadal dysgenesis in the mare are presented. Case No 1 was a pure 63, XO, while Case No 2 was a mosaic with a preponderance of XX cells. The clinical picture was one of phenotypically normal female mares with small uteri and infantile ovaries. The ovaries lacked germ cells, and consisted of stroma only. This study emphasizes the importance of chromosome analysis in providing information concerning the mechanisms involved is some cases of equine infertility.
Symposium on back problems in the horse. Backs-clinical signs. Diseases of the back of horse and man are not comparable owing to the great difference in anatomy and posture. Veterinary surgeons, particularly in the United Kingdom, are often requested to account for a poor performance due to suspected "back trouble" but a complete examination of the horse's back is most difficult and care must be taken first to exclude any limb or foot lesions. Diseases of the bones, nerves and muscles are briefly discussed. Diagnosis must be improved by new radiographic and biochemical tests before the significance of back lesions can be assessed or even treated.
Critical tests of suspension, paste, and pellet formulations of cambendazole in the horse. Three formulations of cambendazole were evaluated for anthelmintic activity by critical testing method in 21 horses. Cambendazole suspension was administered via stomach tube at the dose rate of 10 mg/kg to 3 horses and at the dose rate of 20 mg/kg to 3 horses. Cambendazole paste was given intraorally to 8 horses, and the pellet formulation was fed to 7 horses at the dose rate of 20 mg/kg. Anthelmintic activity of cambendazole was similar for all dose rates and formulations. Gasterophilus intestinalis, Gasterophilus nasalis, Draschia megastoma, Anoplocephala perfoliata, and Anoplocephala magna...
Equine laminitis of alimentary origin: an experimental model. Acute alimentary form of laminitis was uniformly induced in 11 of 12 horses by administration of a starch and wood flour gruel and could be graded by previously established (Obel) and presently defined criteria. The experimentally induced laminitis was similar to naturally occurring laminitis, as determined on the basis of lameness severity and vital signs. Packed cell volume, leukocyte count, and total protein were significantly increased (P smaller than 0.05) at 24 and 40 hours after administration of gruel. Arterial systolic and diastolic pressures increased, central venous pressure decreas...
Symposium on back problems in the horse. (2) The diagnosis of diseases of the horse’s back. A description of some of the clinical features of low back pain in the horse has been given and a number of methods for assisting diagnosis considered. As well as a complete clinical examination both at rest and during exercise, a useful diagnostic aid in some chronic cases was the injection of local anaesthetic into the interspinous spaces. A laboratory examination, including haematological and biochemical profiles, was undertaken in all cases. The serum enzymes GOT and CPK were particularly valuable as an aid to diagnosis in atypical tying-up. A technique for radiography of the vertebral col...
Symposium on back problems in the horse. (3) Diseases of the horse’s spine-“comparative aspects”. The structural differences in the spine of the horse and man are compared. These, together with the different uses to which the spine is put, explain the different patterns of disease. Impingement of the spinous processes is discussed in detail including surgical treatment. Comments are also made on sacroiliac strain and manipulation of the spine.
The technique and clinical appication of endometrial biopsy in the mare. The author describes a technique for obtaining endometrail biopsy specimens from mares. the noraml cyclincal histology of the endometrium and anarbitarry classification histology of the endometrium and an arbitarary classification of the histopathology seen in endometrial biopsy speciemens. Previous literature on the subject is cited. Results of endometrial biopsies taken by the author from 134 barren mares, with histories of subfertility are descirbed and classified. The use of the technique and the interpretationof its find ings in relation to reproductive performance is discussed.
Spindle-cell sarcoma of the equine para-nasal sinuses and nasal chamber. A case of spindle cell sarcoma of the equine para-nasal sinuses is described and discussd in relation to similar tumours recorded in the literature.
[Preliminary studies on the incidence of Filaziae in equidae in the Netherlands (author’s transl)]. Biopsies of the skin of the umbilical area were taken from ninety-nine horses and one donkey, all reared in the Netherlands. The biopsy specimens were examined for the presence of microfilariae by a recovery procedure. Microfilariae were identified in eight horses. These were microfilariae of the species Onchocerca cervicalis in each case.
