Topic:Clinical Symptoms
Clinical symptoms in horses encompass a range of observable signs that may indicate underlying health issues, such as disease, injury, or physiological stress. These symptoms can vary widely depending on the condition and may include changes in behavior, appetite, respiratory patterns, or physical appearance. Common clinical symptoms in horses include lameness, colic, coughing, nasal discharge, and changes in body temperature or heart rate. Identifying and interpreting these symptoms is an essential aspect of equine veterinary practice, as they provide critical information for diagnosis and management of health conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the identification, assessment, and implications of clinical symptoms in equine health management.
Problems in pleasure horse practice. Various common problems encountered daily pleasure horse practice will be discussed covering diagnosis, treatment and prevention.
Horner’s syndrome in the horse: experimental induction and a case report. The findings in 6 experimental and 1 natural case of Horner's Syndrome (HS) are presented. The experimental cases were induced by unilateral surgical section of the cervical sympathetic trunk in the middle third of the neck. The naturally occurring case was seen in a 17 year old gelding with a mediastinal tumour. The signs of HS in these horses included ptosis, miosis, enophthalmos, hemilateral sweating and temperature increase of the face and cranial cervical region on the affected side. The intensity of these signs was variable between and within animals. Miosis, enophthalmos and temperature...
Artifact production with micromanometers used to record intracardiac pressure and sound. In horses experimental right and left heart catheterization using a catheter with two microtransducers 9 cm apart, usually in a transvalval position produced pressure and sound artifacts that confounded the diagnosis. Most were probably due to malpositioning resulting in movement through a valve during recording or impingement on the valve cusps or the chordae tendineae or lodgement in the apex of the heart. The recognition of these artifacts is particularly important in studies of large animals in which catheter siting cannot be monitored by radiography.
General anesthesia in pleasure horses. Anesthetic management of the pleasure horse consists of the appropriate selection and administration of pre-anesthetic medications including anticholinergics, tranquilizers and narcotics followed by appropriate techniques of anesthetic induction. The anesthetic induction must vary somewhat for the pleasure horse practice since many of the procedures are completed on farms and ranches. As a result the inducing of anesthesia will frequently be with the same agent which will be used to maintain anesthesia. Noticeably will be the reduction and duration of anesthesia and surgical time. The inductio...
Special topics in clinical pathology. The following topics are discussed in this presentation: A. Recent advances in the use and interpretation and methodology of antibiotic susceptibility testing. B. Improvements in sample submittal to obtain accurate results from your laboratory. C. Staining blood, bone marrow, and cytology specimens in the office laboratory. D. Pathogenesis and differential diagnosis of lipemia. E. Differential diagnosis of abdominal effusions.
Recovery from anaesthesia in ponies: a comparative study of the effects of isoflurane, enflurane, methoxyflurane and halothane. The duration and quality of recovery after separate 2 hour anaesthetic periods with equipotent alveolar concentrations of isoflurane, enflurane, halothane and methoxyflurane were evaluated in experimental ponies. Recovery was shortest after isoflurane anaesthesia, followed by enflurane, halothane and finally methoxyflurane, although standing was achieved more rapidly after enflurane than after isoflurane. This sequence of recovery times was compatible with the respective solubilities of the 4 agents. The smoothest recovery was obtained after isoflurane anaesthesia, followed by methoxyflurane, ...
Demonstration of specific antibodies in the central nervous system of horses naturally infected with Borna disease virus. From 18 horses with clinical symptoms of an affection of the central nervous system and with histopathologic alterations in the brain, four were demonstrated to have Bornavirus-specific antibodies. The antibodies are monospecific, recognizing identical antigens from infected brains of different animal species as well as from persistently infected tissue culture cells. Discrete immunoglobulin species (oligoclonal IgG) can be demonstrated in concentrated horse cerebrospinal fluid; they carry Bornavirus antibody specificity. Their presence, together with the higher antibody titers in the cerebros...
Black grain mycetoma (maduromycosis) in horses. Black grain mycetoma occurred in two horses, one a cross-bred pony and the other a Thoroughbred racehorse. Lesions were limited to wart-like growths in one case and a deep-seated girth gall in the other. In both cases the granules in the affected tissues were similar in pigmentation and structure to those produced by Curvularia geniculata in dogs. Since all the specimens were received in formalin, the causative fungus could not be isolated. These are the first cases of maduromycosis in animals to be recorded in South Africa.
Some unusual cases of abnormal respiratory noises in the horse. Any condition which leads to a diminution in the size or alteration of the shape of the lumen of the respiratory tract in the horse may result in the production of abnormal respiratory noises at exercise.
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.
Rate of change of halothane concentration in a large animal circle anesthetic system. The slow rate of change of inspired halothane concentration which results in a conventional large animal circle anesthetic delivery system when low carrier gas flow rates are used was confirmed, using a model system. To obtain a 63% change in inspired halothane concentration in the 32-L large animal circle anesthetic machine at fresh gas inflow rates of 3, 6, and 12 L/minute required 10.7, 5.3, and 2.7 minutes, respectively. At a given inflow rate, increasing the rebreathing bag size from 20 to 40 L prolonged the time for equilibration between the gas flowing into the anesthetic circuit and th...
[Veterinary and clinical experience of the use of a beta2-receptor-stimulating sympathicomimetic agent (NAB 365) in horses with respiratory discase (author’s transl)]. The manufacturers state that NAB 365 is a beta2-receptor-stimulating sympathicomimetic agent. According to the medical literature it combines a bronchial antispasmodic effect with certain bronchia secretolytic properties and has few untoward side-effects on, for instance, the heart and intestine. The effectiveness of administration of NAB 365 in horses with chronic or acute respiratory disease was tested in the Department of Veterinary Internal medicine in Utrecht. NAB 365 administered at a dosage of 0.8 gamma/kg, of body weight was found to have a marked bronchodilative effect in horses. Ther...
