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.
Pine oil toxicity in the horse: drug detection, residues and pathological changes. This report concerns the detection and acute toxicity of pine oil (a commercially available disinfectant) after intravenous administration in horses. alpha Terpineol was identified as a major constituent of pine oil. alpha Terpineol was recovered from equine tissues by extraction into heptane and detected by gas chromatography, using either flame ionization detection or pentafluoropropionic anhydride derivatization and electron capture detection. After intravenous injection of 0.1 ml/kg, death due to massive pulmonary edema occurred within minutes. In this animal blood and tissue levels of alp...
The use of Dopram as a respiratory stimulant following Immobilon in the pony. The effects of the analeptic agent, Dopram (doxapram hydrochloride) were investigated in 2 ponies during Immobilon - induced neuroleptanalgesia. Although Dopram was demonstrated to exert a degree of respiratory stimulation, this was concluded to provide no overall advantage. The etorphine-induced hypoxic hypoxia was only partially reversed, and there was additional cardiovascular stimulation, in contrast to the previously reported tendency for arterial blood pressure to return towards conscious control values during the course of action of Immobilon.
An interventricular septal defect, pulmonary stenosis and bicuspid pulmonary valve in a Welsh pony foal. A 6 month Welsh pony filly with an interventricular septal defect in conjunction with a pulmonary stenosis due to a bicuspid pulmonary valve is described. The animal had poor exercise tolerance, a loud pansystolic murmur and a precordial thrill. Blood pressure and oxygen tension values obtained during cardiac catheterization suggested the diagnosis which was confirmed at autopsy.
Diagnosis and surgical treatment of cystlike lesions of the equine paranasal sinuses. Development of cysts in the equine paranasal sinuses is probably a congenital disease; however, signs may not appear for several years. In 4 cases, clinical signs were observed when fluid accumulation within the cysts resulted in nasal discharge or facial swelling, or when secondary infection occurred. Treatment required surgical removal of the lining membrane and other involved tissues. Postoperative care included lavage of the sinuses and systemic antibiotic therapy.
Leukoencephalomalacia: a mycotoxicosis of Equidae caused by Fusarium moniliforme Sheldon. When 2 horses were dosed with cultures of a Fusarium moniliforme isolate that had previously caused only hepatosis, 1 developed brain oedema and hepatosis, and the other only leukoencephalomalacia. A 3rd horse developed both leukoencephalomalacia and hepatosis after being dosed with another isolate obtained from maize which was associated with a natural outbreak of the nervous form of the disease. Since leukoencephalomalacia and hepatosis could be induced by the same culture material, it was concluded that both syndromes were manifestations of the same toxicosis. There was also some evidence t...
Equine infectious anemia. Pyruvate kinase deficiency in the red cells of thoroughbred horses.
Summary:
The authors studied glycolytic and non-glycolytic erythrocytic enzyme activities in 8 thoroughbred horses with equine infectious anemia (EIA) and 16 normal controls. Biochemical lesions were indicated, the most outstanding being a deficiency of pyruvatekinase. Adenvlatekinase could be considered as a “salvage pathway” for the formation of ATP.

Cryosurgical treatment of cancerous and noncancerous diseases of dogs, horses, and cats. Cryosurgery was used to treat a variety of cancerous and noncancerous diseases in dogs, horses, and cats. Follow-up evaluation on 52 animals revealed an overall "no recurrence" rate of 61%. Among the animals with no recurrence were 12 of 17 with cutaneous lesions and 5 of 8 (horses) with sarcoids. Seven of 10 dogs with anal fistulas healed after cryosurgery, but 2 had recurrence of the disease. Treatment of invasive neoplasms of the oral and nasal cavities was not successful. Side effects and complications were minimal.
Diaphragmatic hernia in horses. The clinical and necropsy findings of three cases of diaphragmatic hernia admitted to Ontario Veterinary College between September 1973 and August 1974 are described. The physical signs of these and other reported cases are discussed, as are methods of diagnosis. Definitive diagnosis is best arrived at by exploratory laparotomy.
