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.
Colonic obstructions due to enteroliths in four horses. Four cases of enterolith obstruction in horses aged from six to 14 years are reported. All four cases had symptoms of persistent low grade abdominal pain and anorexia with an absence of defaecation. Examination revealed reduced gut motility and accumulation of gas, but heart and respiratory rates, rectal temperatures and complete blood counts were all within normal limits. Enteroliths of varying sizes were removed from the region of the transverse colon in all four horses.
A case of pituitary adrenocorticotropin-dependent Cushing’s syndrome in the horse. In the horse, a syndrome of hirsutism, hyperglycemia, glucosuria, polydipsia, polyuria, polyphagia, and progressive debilitation has been recognized. Most often the syndrome has been associated with adenomas of the pars intermedia of the pituitary and bilateral adrenal hyperplasia or nodular hyperplasia involving primarily the zona fasciculata. Previously, the syndrome has been ascribed to compression of the hypothalamus by an expanding but functionally inactive pituitary neoplasm. In the present case, with RIA determination of plasma ACTH concentrations, the syndrome was ascribed to pituitary...
Abnormalities in the oestrous cycle in the mare. The situations and conditions that can disrupt the mares normal oestrous cycle are described. Season of the year is a major influence; maximum reproductive efficiency does not totally coincide with the artificially defined "breeding season". Other abnormalities are associated with spontaneously persistent luteal function, psychological influences over behavioural activity, the presence of endometritis, multiple ovulation, reproductive behavior after pregnancy failure and granulosa cell tumours.
Immunotherapy in ocular equine sarcoid. A modified Bacillus Calmette-Guerin (BCG) preparation was used successfully in the treatment of 7 cases of equine sarcoid. The BCG preparation was injected into the lesions. The longest period of remission has been 24 months, and the shortest period of remission has been 9 months, with no signs of recurrence of the tumor in any of the presented cases.
Testicular teratoma in an equine cryptorchid. An abnormal cryptorchid testicle removed from the abdominal cavity of a 4 year old Thoroughbred stallion is described. The abnormal organ conforms to the requirements of Willis (1960) for a teratoma. The difference between these tumours in man and horses is discussed.
Contagious equine metritis–outbreak of the disease in Kentucky and laboratory methods for diagnosing the disease. Contagious Equine Metritis (CEM) was initially reported during the 1977 breeding season in England (Crowhurst, 1977) and Ireland (Timoney, Ward & Kelly, 1977. The disease has also been diagnosed in France and Australia (Huges, Bryden & MacDonald, 1978). The first occurrence of CEM in the United States followed the importation or 2 stallions from France late in 1977 which resulted in an outbreak early in the 1978 breeding season (Swerczek, 1978). Mares usually develop clinical signs of CEM 8--10 days after being covered by an infected stallion, when a copious, greyish discharge is seen. Other m...
Isolation of Klebsiella pneumoniae from the urogenital tract of experimentally infected mares. K. pneumoniae capsule type 68 infused into the uterus of 4 mares was recovered up to 15 weeks after inoculation. The insertion of a tampon for 10 min was more effective than a swab technique in detecting the organism in the uterus. The clitoral fossa and the urethral orifice when sampled by the swab technique were also found to be infected for a comparable period. K. pneumoniae was isolated from the clitoral specimens more often and more consistently than from either urethral or uterine specimens.
The correction of uterine torsion in a mare by caesarean section. A 9-year-old mare exhibiting signs of colic late in pregnancy was presented. Uterine torsion was diagnosed and corrected by caesarean section. A live foal was delivered and the mare survived the surgical interference.
Atresia of the nasolacrimal orifice in two thoroughbreds. Two cases of bilateral atresia of the nasolacrimal orifice are described. The presenting sign was a persistent ocular discharge, clear in the one case and purulent in the other. Treatment by the creation of a fistula between the distal extremity of the blind ending duct and the nasal cavity was successful in both cases.
