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.
Three cases of ruptured mitral valve chordae in the horse. The paper describes clinical observations in three horses with ruptured mitral valve chordae. Horses with ruptured mitral valve chordae may have a history of sudden onset of acute distress with predominantly respiratory symptoms. On auscultation there will be a widespread pansystolic murmur with an extension of the area of cardiac auscultation. The third heart sound may be very pronounced and unduly prolonged, associated with high volume flow during early ventricular filling in diastole. However, these sounds are not specific for chordal rupture--they are typical of severe mitral regurgitation...
Factors limiting the usefulness of histopathologic examination of skin biopsies in the diagnosis of large animal dermatoses. Skin biopsy for histologic, immunofluorescent, parasitologic, and bacteriologic examination is a common procedure, but for maximum effectiveness the clinician must realize the importance of precautions to select the correct stage of lesion of different diseases; avoiding creating artifacts during removal and fixation; and give full details of history, clinical diagnosis, and differential diagnoses on the laboratory request sheet. Pathology reports describing the subtleties of histologic changes are difficult to write, particularly if the lesions are not specific. Overly long histologic reports...
Progressive haematoma of the maxillary sinus in a horse. A nine-and-a-half-year-old three quarters thoroughbred gelding was presented with unilateral epistaxis. The cause was a destructive, progressive haematoma in the left maxillary sinus. In all previous reports of progressive haematomata in the equine nasal cavity, the site of origin has been the ethmoidal labyrinth. Surgical removal of the progressive haematoma resulted in an apparent cure.
Suspected hepatotoxicity in neonatal foals: preliminary report of an emerging syndrome. An apparently new and emerging fatal hepatic disease affecting foals is described. Characteristics included evidence of hepatic failure, marked biliary hyperplasia, hepatocellular necrosis and occasionally fibrosis. Generally, the features of the disease appear to differ markedly from other hepatic diseases of neonatal foals.
Modified Forssell’s operation for crib biting in the horse. Thirty-five horses with a history of crib biting or wind sucking were treated with a modification of the Forssell procedure. The technique involved bilateral neurectomy of the ventral branch of the accessory nerve combined with excision of a portion of the omohyoideus, sternohyoideus, and sternothyroideus muscles. Twenty horses became free of the vice, while in 11 there was a noticeable reduction in frequency of the vice. Four horses returned to crib biting/wind sucking at the same intensity as before surgery. The observation time following each operation was at least 12 months. Complications ...
Clostridial cellulitis in the horse: a report of five cases. Five horses with fatal clostridial cellulitis are described. The characteristic findings were the rapid development of a crepitant swelling with an associated toxemia, which in four cases followed intramuscular injections. The clinical features, diagnostic techniques and pathogenesis are discussed. The importance of an early diagnosis is emphasized.
Observations on the use of glyceryl guaiacolate as an adjunct to general anaesthesia in horses. Twenty-one horses undergoing clinical surgery and diagnostic procedures received 15% glyceryl guaiacolate followed by a rapid intravenous injection of a thiobarbiturate for induction of anaesthesia. Premedication was with atropine and acepromazine. Induction was smooth and free from problems apart from transient apnoea in some horses. Maintenance of anaesthesia was with oxygen and halothane administered by means of a closed circle system with soda-lime absorber and with the vaporiser out of circuit. During the period immediately following induction, the heart rate increased and the respiratory...
Urolithiasis in the horse – a review of 13 cases. The presenting signs, treatment and postoperative progress of 13 horses with vesical and urethral calculi are reviewed. Single, discrete stones were present in 10 animals in which the results of treatment were generally good. In three horses with sabulous cystic deposits, urolithiasis was associated with bladder paralysis and the response to treatment was poor.
[Anesthesia in the horse]. The paper describes the problems of injection anaesthesia in the horse. Different commonly used methods, drugs and drug combinations are explained. Their actions and side-effects are compared and discussed.
[Nutrition and skin diseases in the horse]. Skin diseases of the horse can be produced or enhanced through nutrient deficiency, intestinal formation of detrimental substances, photosensitizing compounds and by intake of allergenes. An exact case history regarding feeding is useful for evaluation of every skin abnormality.
[Hypophyseal adenocarcinoma in a horse. A case study]. The paper presents the case-history of a 5-year-old pony suffering from an adenocarcinoma which proceeded from the pars intermedia of the pituitary gland. Neurological and patho-morphological findings are reported.
The toxicity of Datura stramonium (thorn apple) to horses. Meal contaminated by Datura stramonium seeds at the rate of 0.5% by weight was fed to two horses. Both horses showed clinical signs of depression, anorexia, weight loss, rapi heart and respiration rates, mydriasis, polyuria, polydipsia and diarrhoea. Both recovered with treatment. Maize screenings contaminated by the seeds had been used in the manufacture of the meal.
Culicoides hypersensitivity in the horse: 15 cases in southwestern british columbia. The investigation of a chronic, seasonal dermatitis of horses in southwestern British Columbia is described. Typically the history indicated an insidious onset, followed by a gradual progression in the severity of the signs each year. Lesions appeared during the warmer months of the year and tended to regress during the winter. The clinical signs consisted of areas of pruritus and excoriation, affecting predominantly the ventral midline, mane and tailhead. In all cases corticosteroid therapy relieved the pruritus and allowed the lesions to heal.The salient pathological findings were hyperkerat...
[Cardiovascular complications during anesthesia in horses]. This paper summarizes causes of cardiovascular complications. Treatment of drug related hypotension as well as etiology and therapy of cardiac arrest are discussed.
Chronic chondritis of the arytenoid cartilages in a pony mare. The upper respiratory tract of a pony mare with marked exercise intolerance and respiratory stridor was examined with a flexible fibreoptoscope. Both arytenoids were adducted and distorted. A diagnosis of bilateral chondritis of the arytenoids was made and confirmed at autopsy after surgery to enlarge the rima glottidis was unsuccessful. Other space occupying lesions of the rima glottidis are discussed and theories on the aetiology are postulated.
[Aspergillus oryzae as a cause of keratomycosis in the horse]. A case of a spontaneous mycokeratitis of a previously injured cornea in a horse is described. The infection was caused by Aspergillus oryzae. After application of Chloramphenicol ophthalmic ointment a corneal clouding was found in the centre which was circularly sharply defined and which - after dispensing Dexamethason-Neomycin eye drops - expanded all over to a purulent keratitis. The demarcated and initially non purulent mycotic lesions largely improved after the application of tincture of iodine, whereas the purulent keratitis could be completely cured only by a lasting treatment with Lugol...
