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.
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...
Cervical esophagostomy to permit extraoral feeding of the horse. An indwelling stomach tube was placed through a cervical esophagostomy in 5 clinically normal horses and in 3 horses requiring artificial alimentation. In all but one case, surgery was performed on conscious horses following tranquilization and infiltration of the surgical sites with a local anesthetic. Six horses were fed liquid rations through the indwelling tubes, which were left in place from 3 to 26 days. After the tubes were removed, the stomas healed rapidly and with minimal complications. Cervical esophagostomy proved to be a safe, easy, and effective method for the provision of extrao...
Comparative study of blood coagulation tests in the horse and pony. The clotting times obtained with different assay procedures for routine coagulation tests were examined for horse and pony samples. The whole blood clotting time test and the activated coagulation test seemed to give similar results when both tests were done at 22 C. The results obtained for the activated partial thromboplastin time assay varied, depending on the commercial reagent used for the test. Consistent results were obtained for the one-stage prothrombin time assay with each reagent used.
Immunoglobulins and secretory component in the external secretions of foals with combined immunodeficiency. Nasal washings and tears were collected from seven Arabian foals with combined immunodeficiency and nine normal foals. The major immunoglobulin in the external secretions of normal foals over 2 months of age was secretory immunoglobulin A, whereas foals with combined immunodeficiency lacked this immunoglobulin. The external secretions of both normal and immunodeficient foals contained free secretory component at birth.
Evaluation of inferior check ligament desmotomy for treatment of acquired flexor tendon contracture in the horse. The usefulness of inferior check ligament desmotomy as a treatment for acquired tendon contracture in horses was evaluated in 13 cases of deep digital flexor (DDF) contracture and in 3 cases of combined superficial digital flexor (SDF) and DDF contracture. In 8 of 9 cases of DDF contracture in which the dorsal surface of the hoof had not passed beyond being vertical to the ground, the surgical procedure was successful in returning the limb to a normal position and function. Compared with DDF tenotomy, inferior check ligament desmotomy was a superior treatment technique because of decreased pos...
Interruption of aortic arch in two foals. Two foals with a history of normalcy at birth developed a lack of exercise tolerance and weakness in the first few days of life. Weakness, inability to rise, and reluctance to suckle were common complaints. Physical examination of both foals revealed a cardiovascular abnormality, with a loud systolic murmur audible over both thoracic walls. Additional diagnostic techniques were blood gas analysis, radiography, cardiovascular catheterization, and necropsy. Necropsy findings were ventricular septal defect, atrial septal defect, patent ductus arteriosus, and congenital absence of the aortic arch....
Equine myositis and septicemia caused by Acinetobacter calcoaceticus infection. Myositis and septicemia caused by Acinetobacter calcoaceticus were diagnosed in a mare. The infection was characterized clinically by ventral swelling and edema, diarrhea, listlessness, and rectal temperature of 39.4 C. The mare was treated symptomatically for 2 days but died on the 3rd day. Conditions seen at necropsy were myositis, enteritis, typhlitis, colitis, and hepatitis. Lymph nodes were moderately enlarged throughout the body. Gross lesions in musculature were edema, scarring, petechiae, and an occasional exxhymosis. The enteritis was catarrhal, with excessive mucus and moderate hyper...
[Blood serum biochemistry of ponies (author’s transl)]. A wide blood serum biochemical profile, concerning especially blood lipids has been performed in 31 apparently healthy Shetland and Potiock ponies. These blood standard values will be useful for studies on ponies' hyperlipemia.
Problems in pleasure horse practice. Various common problems encountered daily pleasure horse practice will be discussed covering diagnosis, treatment and prevention.
Chlamydia psittaci infection of horses with respiratory disease. Two strains of Chlamydia psittaci were isolated from the nasal tract of horses with acute respiratory disease. These 2 isolates (NS 121 and NS 172) were characterized as chlamydia on the basis of their morphology, tinctorial property, growth in chicken embryos, inability to grow on bacterial media and their possession of chlamydial common complement fixing group antigen. They were identified as C. psittaci on the basis of resistance to sodium sulphadiazine. The present strains were not pathogenic to mice and guinea pigs and non-toxigenic. They induced antibodies and caused latent infection in ...
Chronic obstructive pulmonary disease (COPD): identification of affected horses. Mean normal values for PaO, and max A Ppl for horses were determined. Using 2 standard deviations below (Pa0,) and above (max A Ppl) the mean normal values as a guide, horses affected with COPD were satisfactorily distinguished from other horses in a series of 100 animals. The frequency of occurrence of 20 different clinical parameters in affected, not affected and possibly affected horses was examined statistically. Poor work performance and a history of previous febrile illness occurred more often in COPD horses than in others. The presence of a chronic cough, dyspnoea, double expiratory eff...
[Diagnosis of infectious anemia in horses using the Coggins test]. Coggins' immune diffusion test was modified, and was applied as a screening one in the study of the epizootic status. The positive reactions were characterized by the production of a precipitation line between the antigen and the respective serum that was tested. The appearance of such a line was associated with that formed with the use of the positive control serum, pointing to a reaction of identity. With the weakly positive reactions the ends of the precipitin lines, formed with the use of the positive control serum, were found to deviate slightly toward the site where the antigen had been ...
The development of a radio-stethoscope for use in the horse at rest and during exercise. The development of a radio-stethoscope for horses is described. The equipment consisted of a sound transducer applied to the skin adjacent to the trachea and a radio transmitter attached to the saddle. The signals emitted were detected by telemetry and recorded on a magnetic tape-recorder. The recorder incorporated a monitor earphone so that sounds could be reproduced at the time of recording. The frequency response obtainable ranged from a few Hz to 4 KHz. This technique provided an objective means of studying the respiratory sounds generated during exercise although absolute values could not...
Equine leptospirosis with some clinical observations. In a serologic survey on equine leptospirosis in Egypt, the following incidences of leptospiral serosensitivity were found: 1. Hospitalised horses 65/113 (57.5 %). 2. Hospitalised donkeys 90/125 (72.0 %). 3. Apparently healthy horses 21/72 (29.1 %). Sera of these animals were mostly reacting to serotypes butembo, pomona, icterohemorragiae, and grippotyphosa. Equine in Egypt are close animals to humans and may constitute a potential source of leptospiral infection. From the clinical point of view, it is very possible that ocular, hoof lesions and icterus in equines would be expected with leptos...

Clinicopathological manifestations of selected neoplasms. This report provides a general overview of the pathobiology of neoplasia, and an update on the clinicopathological manifestations of lymphosarcoma, mastocytoma, histiocytoma, melanoma, sarcoid and circumanal gland tumors in domestic animals. Neoplasia represents a continuum of events from reversible hyperplasia to irreversible and pathological changes in tissue growth patterns. In some instances the causes of this disease process have been identified, but the etiology of the majority of naturally occurring neoplasms remain unknown. Surgical excision is the preferred treatment for tumors, but i...
Vestibular disease, and its relationship to facial paralysis in the horse: a clinical study of 7 cases. The signs observed in 6 cases of peripheral vestibular disease included incoordination, head tilt and nystagmus. The intensity of the signs varied greatly with duration of the disease, and in 3 cases facial paralysis was also present. Tympanosclerosis was demonstrable in all cases subject to radiology. Trauma was the causative factor in most cases. The causes of, and relationships between, vestibular dysfunction and concomitant facial paralysis are discussed. The exact etiology of the tympanosclerosis is unknown.
