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.
Podotrochlear bursa endoscopy in the horse: a cadaver study. To evaluate podotrochlear bursa (navicular bursa) endoscopy as a diagnostic technique in horses and to correlate observations to radiographic and pathologic findings. Methods: Descriptive study. Methods: Seventeen equine cadaver forelimbs. Methods: Five standard radiographic views of the navicular region and a bursographic study with lateromedial and caudal tangential radiographic views were taken of each forelimb. Radiographic scoring of the navicular bone (0, excellent; 1, good; 2, fair; 3, poor) was performed using a previously reported technique. Endoscopic examination was performed using ...
Effect of topical anesthesia of the laryngeal mucosa on upper airway mechanics in exercising horses. To determine the effect of desensitization of the laryngeal mucosal mechanoreceptors on upper airway mechanics in exercising horses. Methods: 6 Standardbreds. Methods: In study 1, videoendoscopic examinations were performed while horses ran on a treadmill with and without topical anesthesia of the laryngeal mucosa. In study 2, peak tracheal and nasopharyngeal pressures and airflows were obtained from horses during incremental treadmill exercise tests, with and without topical anesthesia of the laryngeal mucosa. A nasal occlusion test was performed on each horse while standing during an endosco...

Umbilical evagination of the urinary bladder in a neonatal filly. An 8-hour-old Standardbred filly was evaluated because of an enlarging umbilical mass and stranguria. It was suspected that the mass was the urinary bladder; this was confirmed on surgical exploration of the abdomen. Despite a normal umbilical ring, the bladder had descended and partially everted through its urachal communication with the umbilical stalk. Partial cystectomy and umbilical resection were performed and resulted in an excellent clinical outcome. Evagination of the urinary bladder via the umbilicus has rarely been described in human infants, and, to our knowledge, it has not been r...
Endoscopic assessment of airway function as a predictor of racing performance in Thoroughbred yearlings: 427 cases (1997-2000). To compare endoscopic findings of the upper portion of the respiratory tract in Thoroughbred yearlings with their subsequent race records to determine whether subjective assessment of airway function may be used as a predictor of future racing performance. Methods: Retrospective study. Methods: 427 Thoroughbred yearlings. Methods: Endoscopic examination findings were obtained from the medical records and the videoendoscopic repository of the Keeneland 1996 September yearling sales. Racing records were requested for the yearlings through the end of their 4-year-old racing season (1997-2000). Tw...
Peritonitis associated with Actinobacillus equuli in horses: 51 cases. To review the clinical findings, diagnosis and treatment of 51 horses with peritonitis attributed to Actinobacillus equuli. Methods: Retrospective study of clinical cases. Methods: Breed, age and gender of horse, history, physical examination findings, treatment and outcome were determined from the hospital records of 51 horses in which a diagnosis of peritonitis attributed to A. equuli was made between January 1993 and June 1999. Results of abdominal fluid cytology and bacteriology, antimicrobial sensitivity patterns, haematology and faecal egg counts, when performed, were also retrieved. Res...
Use of the flexion test of the distal forelimb in the sound horse: repeatability and effect of age, gender, weight, height and fetlock joint range of motion. The flexion test of the distal limb is a commonly used clinical tool in both lame and sound horses. In the latter use it is given some predictive value. In recent studies it has been shown that examiner-related factors (force, time) may strongly influence the outcome of the test. In the present study, the possible influences of a number of horse-related factors and short- and long-term repeatability were investigated. Flexion tests were performed by the same researcher in 100 clinically sound horses under standardized conditions. The outcome of the test was scored on a 9-point semiquantitative...
Safety of an oral chondroprotective agent in horses. Six healthy, adult female horses were administered five times the minimum maintenance dose of an oral low-molecular-weight chondroitin sulfate, glucosamine HCl, and manganese ascorbate chondroprotective agent (Cosequin; Nutramax Laboratories, Inc., Edgewood, MD) daily for 35 days. Hematology, serum biochemistry, and synovial fluid parameters were assessed twice prior to administering the product and again at the end of the treatment period. Physical examinations performed daily throughout the study showed no abnormal clinical changes attributable to the product. All hematologic parameters meas...
Radiculomeningomyelitis due to Halicephalobus gingivalis in a horse. An adult horse was euthanatized following a clinical diagnosis of cauda equina neuritis. Significant gross postmortem and histopathologic findings were limited to the sacral spinal cord and cauda equina. The sacral spinal cord, meninges, and spinal nerve roots were expanded and partially effaced by sclerosing granulomatous inflammation with necrosis. The lesion contained numerous nematode larvae and fewer adults with a rhabditiform esophagus having a corpus, isthmus, and valved bulb. Female nematodes were amphidelphic and didelphic with reflexed ovaries. These morphologic features confirm Hali...
Epidemiology of equine grass sickness: a literature review (1909-1999). The geographical spread of grass sickness between 1909 and 1999, particularly in England and Wales, is described, and the experimental investigations to identify a causal agent are summarised. The epidemiological techniques used to investigate grass sickness vary from clinical observations, to more advanced methods such as case-control studies using logistic regression analyses. Several risk factors for grass sickness have been reported consistently (age, time of year and recent movement to new pasture or premises) and several others have been reported for which the findings remain inconsisten...
Determination of the acid-base status in 50 horses admitted with colic between December 1998 and May 1999. The purpose of the present study was to investigate the acid-base status and the concentration of organic acids in horses with colic caused by various disorders. Blood samples were collected from 50 horses with colic and from 20 controls. No intravenous fluids had been given prior to sample collection. Identified causes of colic included gastric ulceration, small intestinal volvulus, cecal intussusception, cecal rupture, colonic impaction, left dorsal colon displacement, right dorsal colon displacement, colonic volvulus, colitis, peritonitis, and uterine torsion. Thirty-seven horses recovered ...
Use of the Accusport semi-automated analyser to determine blood lactate as an aid in the clinical assessment of horses with colic. The most useful diagnostic methods in the initial evaluation of horses with colic assess the morphological and functional status of the gastrointestinal tract and cardiovascular status. This evaluation is best achieved using a combination of clinical and laboratory data. Blood lactate concentration (BL) is one of these variables. BL rises mainly due to poor tissue perfusion and anaerobic glycolysis associated with shock, providing an indicator of both the severity of disease and its prognosis. A hand-held lactate meter, Accusport, provides a rapid (60 seconds), inexpensive dry-chemical-based d...
Fractures of the palmar aspect of the carpal bones in horses: 10 cases (1984-2000). To determine clinical and radiographic findings, treatment, and outcome of horses with fractures of the palmar aspect of the radial carpal bone, with or without concurrent fractures of the palmar surfaces of the other carpal bones. Methods: Retrospective study. Methods: 10 horses. Methods: Medical records were reviewed to obtain information on history, signalment, clinical and radiographic findings, treatment, and outcome. Follow-up information was gathered from owners and referring veterinarians. Results: 7 horses became lame after recovery from general anesthesia for treatment of an unrelate...
The prediction of stress fractures using a ‘stressed volume’ concept. This paper addresses an anomaly which exists in the current literature regarding stress fractures. Analysis of the data on fatigue strength of bone samples in vitro would conclude that these fractures should never occur at the strain levels known to occur in vivo. This anomaly can be resolved by including in the analysis the effect of stressed volume, whereby larger volumes of material are expected to have worse fatigue properties. A Weibull analysis was used to predict the probability of failure, Pf; this was an upper-bound prediction because it did not include the effects of remodelling and ...
Suspected protozoal myeloencephalitis in a two-month-old colt. A two-month-old Appaloosa colt developed neurological signs shortly after birth involving deficits affecting cranial nerves IV, VII, VIII, IX, X and XII, and possibly nerve VI. The most likely differential diagnoses were congenital anomalies, meningoencephalitides, trauma or nutritional causes. The foal was investigated by the analysis of cerebrospinal fluid (CSF), electromyelography (EMG), brain auditory evoked responses, magnetic resonance imaging (MRI), peripheral nerve biopsy, and Western blot analysis for the presence of intrathecal antibodies to Sarcocystis neurona, the causative agent o...
Esophagomyotomy and esophagopexy to create a diverticulum for treatment of chronic esophageal stricture in 2 horses. We report use of esophagomyotomy and esophagopexy to create a diverticulum for relief of chronic type I esophageal stricture in 2 horses. After esophagomyotomy, the mucosa was dissected free from the muscularis for approximately 180 degrees around the myotomy. Then, the tunica muscularis of esophagus was sutured to the sternocephalicus muscle ventrally and the periesophageal tissues dorsally to create a diverticulum without disruption of the esophageal mucosa. Clinical signs of esophageal stricture were relieved, and the horses were fed normal diets without further esophageal obstruction.
Proximal interphalangeal joint arthrodesis in 34 horses using two parallel 5.5-mm cortical bone screws. To report clinical experience with arthrodesis of the proximal interphalangeal joint in horses using two parallel 5.5-mm cortical bone screws placed in lag fashion. Methods: Retrospective, clinical study. Methods: Thirty-four horses, aged 1 to 19 years. Methods: Medical records for all horses admitted (1991-1997) for pastern arthrodesis using two 5.5-mm ASIF cortical bone screws, in parallel orientation, and placed in lag fashion by use of a combined aiming device to facilitate accuracy were reviewed. Signalment, lameness diagnosis, duration of lameness, limb(s) involved, and outcome were reco...
Renal hypoplasia and dysplasia in an American miniature foal. Diagnostic imaging, including computed tomography, of a two-month-old foal with renal failure indicated that its right kidney was probably absent and that its left kidney was abnormal in shape. The foal was stabilised and released, but three days later its clinical signs recurred. Postmortem examination revealed renal hypoplasia and dysplasia, the first reported case of this condition in an American miniature horse.
