Topic:Clinical Findings
Clinical findings in horses encompass a range of observable signs and symptoms identified during veterinary examinations that contribute to diagnosing and managing equine health conditions. These findings can include physical observations, such as changes in behavior, posture, or gait, as well as physiological measurements like heart rate, respiratory rate, and temperature. Diagnostics may also involve laboratory tests, imaging, and other diagnostic procedures to assess organ function and detect abnormalities. Recognizing and interpreting clinical findings are essential components of veterinary practice, aiding in the identification of diseases, monitoring treatment progress, and guiding therapeutic interventions. This page brings together peer-reviewed research studies and scholarly articles that explore the methodologies, interpretations, and implications of clinical findings in the context of equine health care.

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

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 ...
Comparative study of doramectin and fipronil in the treatment of equine chorioptic mange. In equids, chorioptic mange is a common dermatitis for which there are no licensed medications in the uk. Doramectin and fipronil are licensed for the control of ectoparasites in other species and were evaluated for the treatment of 17 cases of chorioptic mange in 13 equids. Equids were included if clinical findings were indicative of chorioptic mange, chorioptes mites were positively identified and concurrent disease that could affect response to disease was not evident. A random number table was used to allocate subjects to receive doramectin (group D, eight animals) or fipronil (group F, ni...
Abortion in a thoroughbred mare associated with an infection with avirulent Rhodococcus equi. An eight-year-old thoroughbred mare with no previous history of illness aborted a fetus at 196 days of gestation, and its internal tissues were examined immunohistologically and bacteriologically. The placenta was not examined, but specimens of the intrauterine fluids and the dam's faeces were collected four days after the abortion and examined bacteriologically. No significant histological lesions were found in the fetus but the amnion and the umbilical cord were oedematous and had petechial haemorrhages. Rhodococcus equi was isolated in pure culture from the lung, heart and stomach contents ...
Pelger-Huët anomaly in an Arabian horse. A 9-year-old Arabian mare was evaluated for a 7-day history of malaise. Results of a CBC included a leukocyte concentration within the reference interval (8.4 x 10(3)/microL, reference interval 6.0-14.0 x 10(3)/microL) with an apparent degenerative left shift (segmented neutrophils 1.2 x 10(3)/microL, reference interval 2.5-7.5 x 10(3)/microL; hyposegmented neutrophils 1.8 x 10(3)/microL, reference interval 0.0-0.2 x 10(3)/microL).

Equine’s Cushing’s Disease: A Clinical Update. The Department of Pharmacology at the North Carolina State University College of Veterinary Medicine is currently conducting stability studies of oral suspensions of pergolide for the treatment of Cushing's disease. While those results are not available at this time, this paper summarizes the results of a literature search on possible clinical treatments for equine Cushing's and is intended to provide insight into the pathophysiology of the disease. Pharmacological options for treatment of equine Cushing's are discussed.
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...

Papillary renal adenoma of distal nephron differentiation in a horse. A 20-year-old thoroughbred mare had a mass in the right kidney. The mass was encapsulated with fibrous capsule and composed of variably-sized papillary projections lined by a single layer of flattened to cuboidal neoplastic epithelial cells with no cytological and nuclear atypia. Immunohistochemically, the neoplastic cells were broadly positive for cytokeratin AE1/AE3 and granular staining for alpha-1-antitrypsin was focally detected; this immunohistochemical property was similar to that of the normal distal nephron. From these results, this case was diagnosed as papillary renal adenoma of dis...
Validation of computerized Swedish horse insurance data against veterinary clinical records. The aim was to evaluate the agreement between computerized insurance data in a large Swedish horse insurance database and the information in the corresponding clinical records (CR). A random sample of 400 veterinary care and 140 life claims was included. Information on name of the horse, breed and gender, year of birth, specific diagnosis and system diagnosis (e.g. joints, digestive and skeletal) was compared between sources. The concordance for demographic variables was categorized as agreement, disagreement or data missing. For diagnostic information, the categories were agreement, minor dis...

Evidence-based medicine in equine critical care. One of the fundamental skills required for practicing evidence-based medicine is the development of a well-built clinical question, which specifies the patient group or problem, intervention, and outcome of interest. For this purpose, various "levels of evidence" have been developed in the human literature, which rank the validity of evidence. Our established conclusions and advice are thus supported by specific "grades of recommendations," which are intended to give an indication of the "strength" of a clinical recommendation. This article was compiled with these principles in mind.
Evidence-based literature pertaining to thyroid dysfunction and Cushing’s syndrome in the horse. The evidence-based literature pertaining to thyroid dysfunction and Cushing's syndrome is discussed in this article. Summaries of and recommendations for the treatment of these conditions are made. There is a need for reliable diagnostic tests for these conditions in horses.
Common procedures in broodmare practice: what is the evidence? Many procedures performed as part of routine broodmare practice are based on sound clinical judgment and experience or scientific evidence; however, others are based on perceived problems and needs to address them. This article presents four procedures commonly used in broodmare practice, for which there is questionable evidence to substantiate their use.
Evidence-based lameness detection and quantification. Kinematic and kinetic gait analysis potentially offers veterinarians an objective method of determining equine limb lameness. Subjective analyses have been shown to be somewhat flawed, and there does not seem to be a high degree of intraobserver agreement when evaluating individual horses. In addition, recognition of the compensatory effects of primary lameness may be helpful for the practicing equine veterinarian.
Evidence-based parasitology in horses. This article focuses on what has been established concerning the interaction of equine parasites and their hosts, highlighting those issues for which convincing data are still lacking. There is a compelling need for the participation of the veterinarian in the design of appropriate anthelmintic treatments and prevention strategies.
Tri-level surgical treatment of cervical spinal cord compression in a Thoroughbred yearling. A Thoroughbred yearling was presented with neurological, radiographic, and myelographic abnormalities consistent with cervical vertebral stenotic myelopathy. Surgical correction was performed by using ventral cervical interbody fusion at 3 intervertebral spaces. The patient recovered uneventfully from surgery. The neurological status remained unchanged initially; however, significant improvement was noted 37 weeks postoperatively. Un Thoroughbred d’un an a été présenté avec des anomalies neurologiques, radiographiques et myélographiques compatibles avec une myélopathie sténosée des ...
An evidence-based approach to clinical questions in the practice of equine neurology. The practice of equine neurology has special challenges posed by the size of the animal being examined. Many diagnostic procedures routinely used in small animal practice are unsafe when applied to the equine patient or unavailable to the equine practitioner. Therefore, astute observation is the mainstay of making a neuroanatomic diagnosis, and detailed evidence on the deficits present may be difficult to obtain. Because clinical observation can sometimes be ambiguous and somewhat subjective, it is even more important to approach equine neurology from an evidence-based point of view. Here, suc...
