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.
Congenital occipitoatlantoaxial malformations in the horse. From a clinical, radiological and morphological study of 9 horses with congenital malformations of the occiput, atlas and axis, and from a study of 2 reported cases, 3 diseases were defined: A. Familial occipitalisation of the atlas with atlantalisation of the axis in Arabian horses (7 cases in this report and the case reported by Leipold, et al., 1974). These horses had congenital atlantooccipital fusion, hypoplasia of the atlas and dens, malformation of the axis and modification of the atlantoaxial joint. B. Congenital asymmetrical occipitoatlantoaxial malformation (2 cases in this report). ...

Surgical implications of extensibility of the skin of the equine carpus. To determine the lines of maximum extensibility of the skin over the equine carpus, round puncture wounds were made 2.0 cm apart over the carpal area of 5 horses (7 carpi). The direction of elongation of the round puncture wound was observed and photographed. Lines of maximum extensibility that occurred over the surfaces of the equine carpus were determined to be proximal to distal, except in a small area over the accessory carpal bone where a state of anisotropism existed. In an immobilized carpus, direction of a surgical incision was not as important as it was in a mobile carpus, in which th...
[Occurence of an outbreak of horse dermatophytosis caused by the fungus Trichophyton equinum]. There is a description of equine dermatophytosis enzootic, caused by the microscopic fungus Trichophyton equinum. The disease affected 32 horses, mostly young, all in the same herd (74.4%). The diseased horses were successfully treated with the preparation Fenoform forte, applied superficially at the concentration of 0.5% of the active substance. The authors made an attempt to determine the criteria for clinical differentiation of fully developed trichophytosis and microsporosis of horses. Trichophytosis (T. equinum) is characterized as typical numerous small and round patches, covered by smal...
Guttural pouch mycosis in two horses. The history and clinical findings of 1 horses with guttural pouch mycosis referred to us are described. The salient features of the history and clinical signs common to both cases were profuse spontaneous nasal haemorrhage, partial pharyngeal paralysis; subsequently bilateral nasal discharge containing food material, inability to drink and parotid pain became evident. One case made a gradual recovery with conservative medical treatment while the second case was destroyed and submitted for post-mortem, histopathological and microbiological examination. This examination failed to establish the i...
Retrospective study of 350 cases of equine cryptorchidism. Equine cryptorchidism was examined by a review of the literature and a retrospective study of 350 horses over a 14-year period. The incidence of left vs right testis retention was nearly equal. On the left side, 75.2% of the retained testes were retained abdominally and 24.8% inguinally; on the right side, 41.8% of the retained testes were retained abdominally and 58.2% inguinally. Preoperative diagnosis by rectal palpation of the vaginal rings was considered a valuable technique, with 87.9% accuracy in 190 horses. Invasive and nonivasive surgical techniques for abdominal cryptorchidectomy and...
Role of intracranial [H+] receptor in physiologic regulation of ventilation in ponies. Numerous studies have demonstrated the existence of an intracranial [H+] chemoreceptor mechanism capable of stimulating ventilation. 1 Supposedly, this chemoreceptor is located 0.2 mm below the surface of the ventrolateral side of the medulla and is responsive to [H+] in the surrounding cerebral extracellular fluid (ECF). During chronic conditions, ECF [H+] is supposedly in equilibrium with CSF [H+]; hence, stimulus level can be established through sampling and analysis of CSF. In this presentation, we summarize data from studies on spontaneously breathing, unanesthetized ponies which suggests...
The use of electrocardiography in the diagnosis of poor racing performance in the horse. Electrocardiograms were reocrded from 153 racehorses and 10 Olympic three-day-event horses. The horses were then grouped into those presented for routine examination, those in which there was a complaint of poor performance, those going to the Montreal Olympics, and those with upper respiratory tract abnormalities. When the ECGs of the four groups were compared on the basis of detection of abnormality, it was found that 93.2% of the poor performance group showed abnormalities of various types. The routine examination group showed 21.1% of horses with abnormal ECGs, and over half of these have ...
Cyclic and pathologic changes of the mare endometrium as detected by biopsy, with a note on early embryonic death. Normal histologic changes that occurred in concert with the ovarian cycle were evaluated. When combined with behavioral and physical findings, this evaluation enabled determination when there was synchrony between ovarian steroids (estrogen and progesterone) and their target tissues of endometrium. A system for classification as well as definitions of patterns types and degrees of severity of inflammatory and fibrotic changes was developed to facilitate a uniform system for description and communication. An attempt was made to relate the pathologic changes to their effect on fertility when fer...
Epiglottic entrapment by arytenoepiglottic folds in the horse. An abnormality of the epiglottis and arytenoepiglottic folds that caused epiglottic entrapment was diagnosed in 21 horses. Until recently, this entrapment was poorly understood. Definitive diagnosis of epiglottic entrapment can be made only by endoscopic examination of the epiglottis, arytenoepiglottic folds, and soft palate to differentiate the abnormality from dorsal displacement of the soft palate. Dorsal displacement of the soft palate is often associated with entrapped epiglottis. Epiglottic deformity, especially hypoplasia, is often associated with the entrapment. The abnormality was det...
