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.

To describe management of anesthesia for transvenous electrical cardioversion (TVEC) in horses and report perianesthetic complications. Methods: Retrospective case series. Methods: 62 horses with atrial fibrillation and without underlying cardiac disease and 60 horses without atrial fibrillation. Methods: Medical records of horses with atrial fibrillation anesthetized for TVEC were reviewed, as were records of horses without atrial fibrillation anesthetized for magnetic resonance imaging (MRI). The TVEC group horses were compared with MRI group horses for incidence of intraoperative bradycardi...
Surgical management and outcome of a type-III Salter-Harris fracture of the frontal plane of the distal radial physis in a foal. A 4-week-old Thoroughbred filly presented with lameness of acute, severe onset of the left foreleg (LF) of 3 days' duration. Results: Diffuse swelling was present around the distal radius and carpus of the LF. Carpal varus that could be reduced manually was present. Radiographs revealed an intra- articular frontal-plane fracture in the distal radial epiphysis, which continued cranially through the distal radial physis (DRP). The lateral aspect of the DRP was wider than expected. Latero-medial carpal instability was resolved by placement of a lag screw from the dorsal midline through the epiphy...
In vitro susceptibility patterns of fungi associated with keratomycosis in horses of the northeastern United States: 68 cases (1987-2006). To determine in vitro susceptibility patterns of fungi associated with keratomycosis in horses in the northeastern United States and compare those patterns with results of studies from other geographic regions. Methods: Retrospective case series. Methods: 68 horses with keratomycosis. Methods: Medical records of horses with a clinical diagnosis of keratomycosis, positive results of corneal fungal cultures, and susceptibility data were reviewed from the years 1987 to 2006. Fungal identification and in vitro antifungal susceptibility test results were recorded. The percentage of susceptible isol...
Clinical use of the locking compression plate (LCP) in horses: a retrospective study of 31 cases (2004-2006). Fracture repair and arthrodesis in horses require rigid fixation in order to achieve early post operative comfort. The locking compression plate (LCP) was designed to allow greater stability and less periosteal disruption than conventional plates. Objective: To describe a series of clinical cases in which the LCP was used for fracture stabilisation or arthrodesis. Methods: Medical records, radiographs and follow-up for 31 horses having fracture stabilisation or arthrodesis with the LCP were reviewed. Reasons for treatment included fracture of the olecranon (n = 2), metatarsal III (n = 2), ilia...
The case of Glyn vs. McGarel Groves. No abstract available
Concurrent atypical myopathy and equine dysautonomia in two horses. This report concerns 2 horses that suffered typical clinical signs of atypical myopathy (AM) and equine grass sickness (EGS) concurrently. Clinical details and pathological lesions of the cases are described. EGS and AM are relatively rare diseases and the concurrency of the diseases in the same animals is therefore considered unlikely to be a coincidence. However, it is not suggested that the evidence shows a common aetiology but rather the existence of common predisposing causes.
Comparison of tracheal aspirates before and after high-speed treadmill exercise in racehorses. To determine whether percentages of neutrophils in tracheal aspirate (TA) samples collected from racehorses are increased after exercise and whether interpretation of results from TA samples taken before and after exercise agree. Methods: Case series of 40 young Thoroughbred and Standardbred racehorses in race training presented for evaluation of poor performance. Methods: TA samples were collected endoscopically from racehorses presented for poor performance 24 h before and 1 to 2 h after high speed treadmill exercise testing. Aliquots of the retrieved fluid were cytocentrifuged and smears we...
Decreased radiopharmaceutical uptake (photopenia) in delayed phase scintigraphic images in three horses. Decreased radiopharmaceutical uptake, photopenia, in delayed phase scintigraphic images is recognized in people but has only been reported rarely in horses. We describe three horses with septic osteitis, bone sequestrum formation, or distal limb thrombosis that had photopenia of the affected extremity. Photopenia may indicate the presence of ischemia and can be used to facilitate clinical decision making and prognosis assessment
Outbreak of Q fever associated with a horse-boarding ranch, Colorado, 2005. Coxiella burnetii is a bacterium located worldwide that can cause Q fever when inhaled. We describe an outbreak of Q fever associated with a horse-boarding ranch that had acquired two herds of goats. We conducted case finding and cohort studies among persons who boarded horses on the ranch and ranchers and among residents in the surrounding community, and conducted sampling of the goats and environment, to determine risk factors for infection and guide public health interventions. Sixty-six ranchers and persons who boarded horses on the ranch were interviewed; 62 (94%) were not professional ra...
Comparison of the diagnosis and management of unilaterally castrated and cryptorchid horses at a referral hospital: 60 cases (2002-2006). To determine the incidence of unilaterally castrated horses among horses admitted to the hospital for castration and to compare horses that underwent previous unilateral castration with horses that had cryptorchism. Methods: Retrospective case series. Methods: 16 unilaterally castrated horses and 44 cryptorchid horses. Methods: Medical records of horses that were admitted to the veterinary medical teaching hospital for castration, including cryptorchid and unilaterally castrated horses, between January 2002 and December 2006 were reviewed. Medical records of unilaterally castrated horses and c...
Application of arm-specific painting probes of horse X chromosome for karyotype analysis in an infertile Hutsul mare with 64,XX/65,XX+Xp karyotype: case report. A 5-year-old infertile Hutsul mare was subjected to cytogenetic analysis. Fluorescence in situ hybridisation (FISH) using the equine Xp and Xq chromosome painting probes was carried out on chromosome preparations obtained after blood lymphocyte culture. These probes were generated by chromosome microdissection and a large number of spreads was analysed (525). The karyotype formula of the analysed mare was 64,XX/65,XX+Xp with the ratio of the two lines being 99.4 and 0.6, respectively. The goal of the study was to apply chromosome microdissection and the FISH technique for cytogenetic diagnosti...
Omental leiomyoma in a male adult horse. A well-circumscribed mass 70 x 35 x 28 cm in size and 41 kg in weight was detected at necropsy in a male adult horse within the omentum major without any association to the gastrointestinal tract. The tumor consisted of multiple white-to-yellow lobules and displayed a firm consistency. In addition, multiple cysts filled with blood-like fluid, and multifocal areas of necrosis were observed. Histologically, the mass consisted of slightly pleomorphic spindloid-shaped cells arranged in interlacing bundles containing elongated nuclei with blunt ends. The majority of tumor cells revealed a positive ...
Glossitis and tongue trauma subsequent to administration of an oral medication, using an udder infusion cannula, in a horse. A 10-year-old gelding was presented with a tongue that had swelled immediately after oral administration of oxfendazole, using an udder infusion cannula. The tongue appeared to have been punctured inadvertently. The horse recovered after treatment with intravenous fluid, antibiotics, and anti-inflammatory drugs. Administering oral medication by this method should be discouraged. Un cheval hongre âgé de 10 ans a été présenté avec une langue devenue tuméfiée immédiatement après l’administration orale d’oxfendazole à l’aide d’une canule à infusion du pis. La langue semblait a...
Persistent dorsal displacement of the soft palate attributable to a frenulum of the epiglottis in a racing Thoroughbred. A 7-year-old sexually intact male Thoroughbred racehorse was evaluated because of exercise intolerance, respiratory tract noise, and coughing when eating. Results: A persistent dorsal displacement of the soft palate was identified during endoscopic examination of the upper portions of the respiratory tract. Radiography of the pharyngeal and laryngeal regions revealed a hypoplastic epiglottis that was ventral to, and not in contact with, the soft palate. The horse was anesthetized, and an oral endoscopic examination revealed a subepiglottic frenulum that had resulted in the dorsal displacement ...
Gabapentin for the treatment of neuropathic pain in a pregnant horse. A 24-year-old 732-kg (1,610-lb) pregnant Belgian draft horse mare developed neuropathy and signs of intractable pain following colic surgery. Results: Following recovery from colic surgery to treat compression of the small and large intestines because of a large fetus, the mare was noticed to have signs of femoral neuropathy involving the left hind limb. Within 36 hours after recovery, the mare developed signs of severe pain that were unresponsive to conventional treatment. No gastrointestinal tract or muscular abnormalities were found, and the discomfort was attributed to neuropathic pain. Re...
Equine idiopathic cheek teeth fractures: part 2: a practice-based survey of 147 affected horses in Britain and Ireland. There is limited information on the prevalence of idiopathic cheek teeth (CT) fractures in the general equine population and on which CT are most commonly affected. Objective: To obtain information on the prevalence of fracture patterns and clinical details of idiopathic CT fractures. Methods: Details of cases with idiopathic CT fractures encountered were obtained via a questionnaire sent to suitably experienced veterinary practitioners and equine dental technicians (EDTs). Results: Details of 147 horses that suffered a total of 182 idiopathic CT fractures; and median 0.4% (range 0.07-5.9%) of...
The judgement of Solomon and journal status. In the preceding 2 issues, March and May, editorials were presented
regarding the generality of peer review and the relationship of
authors to readership. In this issue, the outcome of peer review and
content of the Journal is considered as a logical end-point of
endeavours of authors and editors. Science is a hard taskmaster for
both of these participants; it is about what is; and not about what
would be nice, desirable or, even, applicable. The content of any
scientific Journal is presented in order to advance knowledge and is
thereby constrained by correspondingly strict disciplines...
Treatment in the field of 27 horses with epiglottic entrapment. Twenty-seven horses were treated for epiglottic entrapment by using an oral, hand-assisted bistoury knife technique, under general anaesthesia; 26 of them returned successfully to racing, but one developed a permanently displaced soft palate. After the surgery 13 of the horses had an increased handicap rating and 13 had a decreased rating.
