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.
Complications and survival associated with surgical compared with medical management of horses with duodenitis-proximal jejunitis. Based on clinical observation, it is hypothesised that horses with duodenitis-proximal jejunitis (DPJ) that are treated surgically have a shorter duration, smaller volume, and slower rate of nasogastric reflux (NGR) compared to horses treated medically, are more likely to develop diarrhoea than medically managed cases, and have a higher incisional infection rate than a sample population of horses undergoing abdominal exploration for gastrointestinal disease other than DPJ. Objective: To compare: 1) duration, volume and rate of NGR and the percentage of horses with diarrhoea between medically a...
Peripheral blood leukocytes. Assessment of peripheral blood leukocytes is the most common clinical pathology test in equine practice. It is always a part of complete body function assessment and frequently is used alone, or in conjunction with, fibrinogen to monitor response to treatment.
Equine synovial fluid analysis. The most important application for synovial fluid (SF) analysis in the horse is in the diagnosis of synovial sepsis. Misdiagnosis of synovial sepsis is costly, and SF analysis makes correct diagnosis more likely, although far from certain. The precision of diagnosis may be increased with polymerase chain reaction analysis for detection of bacterial DNA in SF and with assays for various enzymes and cytokines. These tests are currently not widely available, however, and routine SF analysis remains of prime importance in diagnosis.
Clinical pathology of the foal. The neonatal foal is in a period of transition between fetal and extrauterine life. The clinicopathologic findings in this period often reflect the in utero environment; thus, results need to be interpreted with the knowledge of changes that intrauterine life may produce. These changes can also assist the veterinarian in identifying a foal at high risk for developing clinical problems. The veterinarian should also be aware of the normal variations in clinicopathologic findings that occur as the foal matures. As with results from all diagnostic testing, the clinicopathologic results need to be ...
Urinary clinical pathologic findings and glomerular filtration rate in the horse. Urinary specific gravity (USG) measurements are underused by equine ambulatory veterinarians. Urinary dipstick and USG findings can assist in the diagnosis and prognosis of many disease processes in the horse. Simple methods for measurement of the glomerular filtration rate and urinary biochemical markers can improve equine urinary diagnostic abilities in critical care patients. Fractional excretion of electrolytes and minerals assists in fluid care and in management of nutrition of horses.
Erythrocytes. In this article, the normal kinetics, morphology and other unique characteristics of equine erythrocytes are reviewed, the influence of the spleen on erythrocyte values is discussed, and selected normal reference intervals are presented. In addition, the classification and causes of anemia and polycythemia are reviewed and the appropriate laboratory tests for accurate diagnosis are presented.
Exophthalmus secondary to a sinonasal cyst in a horse. A 13-year-old female Miniature Horse was evaluated for progressive unilateral exophthalmia of the left globe of 3 weeks' duration. Results: Results of a physical examination were unremarkable. Ophthalmic examination identified exophthalmus of the left globe with complete resistance to retropulsion and mild blepharoconjunctivitis. Computed tomography revealed a large, space-occupying mass within the left caudal maxillary and left conchofrontal sinuses. The mass extended into the left retrobulbar space and contacted the cribriform plate. Trephination yielded copious amounts of turbid yellow flui...
Characteristic of inflammatory airway disease in Japanese thoroughbred racehorses. Inflammatory airway disease (IAD) is a common cause of poor performance, interruption of training and premature retirement in racehorses. It is also reported that up to 80% of horses are affected at some point in the first years of training in UK and Australia. However, no studies with regard to the information on occurrence of IAD in Japanese Thoroughbred racehorses have been reported. To investigate the occurrence and the characteristics of IAD, epidemic research including endoscopic examination of the airway tract and trachea wash was conducted for Thoroughbred racehorses presenting coughs ...

Radiographic parameters for diagnosing sand colic in horses. Ingestion of sand can cause colic, diarrhoea and weight loss in horses, but these signs are unspecific and can have many other causes. The amount of sand that induces disease may vary between individuals. To avoid over-diagnosing, it is important to determine the amount of sand that can be found in horses without clinical signs of gastrointestinal disease. The aim of this study was to use previously suggested parameters for establishing a radiographic diagnosis of sand colic, and compare these findings between a sand colic group and a control group. Methods: Abdominal radiographs were obtained...
Electrochemotherapy in veterinary oncology. Electropermeabilization is a method that uses electric field pulses to induce an electrically mediated reorganization of the plasma membrane of cells. Electrochemotherapy combines local or systemic administration of chemotherapeutic drugs such as bleomycin or cisplatin that have poor membrane permeability with electropermeabilization by direct application of electric pulses to the tumors. Preclinical studies have demonstrated excellent antitumor effectiveness of electrochemotherapy on different animal models and various tumor types, minimal toxicity, and safety of the procedure. Based on resul...
What is your diagnosis? Pleural fluid from a neonatal Thoroughbred filly with pneumonia. A 3-day-old filly was presented to the Cornell University Hospital for Animals with an umbilical hematoma and mild aspiration pneumonia. The foal underwent abdominal surgery for resection of the hematoma. Recovery was uneventful, but 3 days after surgery, the foal became progressively tachypneic. Imaging studies revealed bilateral pleural effusion and pleuropneumonia. Cytologic evaluation and bacterial culture of the pleural fluid from both sides of the chest revealed sterile exudates, consisting mostly of neutrophils, with fewer macrophages and lymphocytes. Pleural fluid macrophages contained...
What is your diagnosis? Peritoneal fluid from an Arabian horse after colic surgery. A 16-year-old castrated male Arabian horse was presented to the Purdue University Veterinary Teaching Hospital with a 4-hour history of colic. Initial examinations provided strong evidence for small intestinal obstruction. Abdominal surgery revealed a strangulating lipoma, and 25 feet of small intestine were resected. Postoperatively, the horse developed obstructive ileus due to adhesion formation, which required a second laparotomy. During and after surgery, the abdomen was lavaged with sodium carboxymethylcellulose (CMC). One week after the second surgery, evaluation of peritoneal fluid reve...
Evaluation of three methods for measurement of hemoglobin and calculated hemoglobin parameters with the ADVIA 2120 and ADVIA 120 in dogs, cats, and horses. Besides flow cytometric detection of cellular hemoglobin (HGB) concentration, the ADVIA 2120 uses a novel cyanide-free colorimetric method to determine extracellular total HGB concentration. In human samples, the results are equivalent to those of the cyanmethemoglobin method on the ADVIA 120. Cyanide-free HGB measurement has not been evaluated in animal samples. Objective: The aim of this prospective study was to compare the 3 methods of HGB analysis on the ADVIA 2120 and ADVIA 120 in blood samples from dogs, cats, and horses. Methods: Consecutive fresh K(3)EDTA blood samples from 119 dogs, 1...

Un poulain Quarter horse âgé de 10 jours a été présenté pour des signes de désorientation et d’incapacité à se nourrir. Une hydronéphrose/hydrouretères avec pyélonéphrite concomitante et débalancement électrolytique sévère ont été diagno...
Prevalence of gastric ulcers in Thoroughbred broodmares in pasture: a preliminary report. Gastroscopic examinations were performed in 62 Thoroughbred broodmares (33 pregnant, 29 non-pregnant) at one breeding farm to investigate the prevalence of gastric ulceration. Age, pregnancy status, race earnings, last race start, herd size, medical history, number of live foals, breeding years, feed type and number of feedings were recorded, plus coat condition and body condition score were determined. Twenty-one mares were re-evaluated after foaling, and the foaling date, foal weight at birth and placenta weight were recorded. The overall prevalence of gastric ulcers was 70.9%, with a median...
Usability of normal force distribution measurements to evaluate asymmetrical loading of the back of the horse and different rider positions on a standing horse. Pressure measurement devices in equine sports have primarily focused on tack (saddle pads and saddle fitting methods). However, saddle pressure devices may also be useful in evaluating the interaction and distribution of normal forces between the horse and rider, including rider position and riding technique. This study examined the validity, reliability, repeatability and possibilities of using a saddle pressure device to evaluate rider position. All measurements were performed using a standing horse. Validity was tested by calculating the correlation coefficient between measured normal force...
Evaluation of ‘Section-Ligation-Release (SLR)’ technique devised for castration in the stallion. A novel technique [Section-Ligation-Release (SLR)] was evaluated for castration in the horse. Clinical traits, serum testosterone concentrations after challenge with human chorionic gonadotrophin (hCG), and histopathological changes of the testicular tissue were assessed. Five stallions, aged 24-48 months, were castrated using SLR technique under general anaesthesia. Both spermatic cords in each stallion were exposed at the scrotal neck by two 5-cm long incisions, followed by sharp dissection through the parietal vaginal tunic. Both vascular and non-vascular structures in the cords were triple...
