Topic:Clinical Examination
Clinical examination in horses involves a systematic evaluation of the animal to assess its health status and identify any potential medical issues. This process typically includes a thorough physical assessment, which may cover observation of behavior and posture, palpation of body structures, auscultation of heart and lung sounds, and examination of the skin, eyes, and mucous membranes. Additional diagnostic tools such as thermography, endoscopy, or imaging techniques may be utilized to gather more detailed information. Clinical examination serves as a foundational step in veterinary diagnostics, aiding in the detection and management of diseases or injuries in horses. This page compiles peer-reviewed research studies and scholarly articles that explore methodologies, advancements, and findings related to clinical examination practices in equine medicine.
Diagnostic value of tissue biopsy in gastrointestinal and liver disease. Methods are described for the endoscopic examination and biopsy of the gastrointestinal tract and liver of the dog, cat, ox and horse. The results of the examination of 41 biopsy samples are shown, followed by a discussion of the value of biopsy in the diagnosis of diseases of the digestive tract.
Use of ultrasonography for the detection of aortic-iliac thrombosis in horses. Two dimensional ultrasonographic evaluation of the iliac arteries and terminal portion of the aorta was utilized in 18 horses with histories of exercise intolerance or hindlimb lameness. A plaque or thrombus was imaged in one or more of these vessels in 5 horses. In 2 horses, the initial rectal examination findings were normal and the thrombus may have been missed without the use of diagnostic ultrasonography.
Clinical features and treatment of renal tubular acidosis in two horses. Two horses were admitted separately for evaluation and treatment of profound hyperchloremic metabolic acidosis without azotemia. One, an 11-year-old Quarter Horse mare, had been depressed and ataxic for 2 days. The other, a 2-year-old Quarter Horse colt, had a 6-week history of depression, anorexia, and weight loss. Both horses responded to fluid and electrolyte therapy, but required daily oral administration of sodium bicarbonate for maintenance. In each case, the diagnosis was renal tubular acidosis.
Observations on tracheal mucociliary clearance in horses. The rate of movement up the mucociliary escalator of Technetium99m tagged to macroaggregated albumin was measured in 7 normal horses and 8 with respiratory disease. The activity at 2 sites in the neck, separated by 12-15 cm, was measured using a hand held scintillation counter and rate meter. In normal horses the Technetium complex moved as a bolus up the neck with a mean rate of 1.58 cm/min. In the horses with respiratory disease the Technetium complex was less likely to move as a discrete bolus and in three horses it was not possible to measure the transport rate. The remainder had a mean tr...
Evaluation and management of respiratory disease in the horse. Respiratory disease is one of the commonest medical reasons for referring a horse to the Royal Veterinary College, with coughing the main presenting sign. Investigation requires the taking of a detailed history, clinical examination, the use of appropriate diagnostic aids and noting response to medication and management changes. On arrival the horse is stabled in a minimal dust environment, remaining there until discharge. The use of a dust-free box frequently produces a favourable response without the use of medication which in itself is diagnostic. The problem of a horse which is asymptomati...
[Neurological examination of the horse]. Neurological examination in equine practice, physiological findings and pathological disturbances are described. Because of the sizes of the horse the neurological examination is more difficult than in small animals. The examination of cerebrospinal fluid is a worthful completion and is able to refer to the etiology of a certain disease. The technique of the puncture of cerebrospinal fluid is described.
Effects of cromolyn in horses with chronic obstructive pulmonary disease. The effect of disodium cromoglycate (cromolyn) in preventing the pulmonary dysfunction caused by the inhalation of barn and hay dust was studied in 5 horses with confirmed chronic obstructive pulmonary disease (COPD). The horses were studied before (Con) and after exposure to hay and dust allergens (Expos) and after pretreatment with cromolyn followed by exposure (Cr-Expos). There was a significant reduction in PaO2 from 86.8 +/- 8.3 to 73.1 +/- 8.8 when the horses were exposed to hay and dust allergens. The PaO2 after pretreatment with cromolyn and exposures was 78.1 +/- 5.5. There were no si...
[Legal aspects of veterinary examinations of horses at purchase with regard to the new high court decision and prevailing dogma]. The existing statutory provisions in connection with the seller's liability for defects of a horse are nowadays unsatisfactory. This has led to an increasing number of cases in which veterinarians have been held liable for the purchaser's damages resulting from an incorrect or incomplete veterinary examination at point of sale. Courts have recently imposed extensive duties of care on the veterinary. He has not only to detect and disclose every minute defect of the horse, but has to give a prognosis of the development of the horse's healthiness and its future capability to meet the purchaser's ...
[Hoof correction in foals]. The conformation of a foal's limbs is of interest beginning in the first days of life. The hoof also must not be neglected. Management and hoof care necessary for normal hoof development are discussed. In addition, pathological hoof shapes and their appropriate treatments are outlined.
Acetabular osteochondrosis dissecans in a foal. Osteochondrosis affecting the acetabula in horses is rarely reported. Osteochondrosis dissecans in foals only a few weeks old is also an uncommon finding. Lesions compatible with osteochondrosis dissecans in the acetabulum were found to be the cause of a chronic coxofemoral lameness in a 3-week-old Arabian filly. The history, physical examination findings, joint fluid analysis, gross pathologic and histopathologic findings are described.
[Examination and treatment of respiratory tract diseases in the horse in clinical practice]. In spite of regular vaccinations against equine influenza we are still observing a high rate of patients with respiratory problems in the equine practice. In our practice in Munich Riem, into which a horse clinic has been integrated, 4000 horses have been treated in 1985 alone. 874 of these showed some form of respiratory disease (= 22%). All of the 4000 horses have only been treated curatively, i.e. preventive forms of treatment such as vaccinations, deworming and examinations for insurance companies and prior to selling have not been taken into account. From 1983 until today in our clinic 25...
[Endometrial cysts in the mare. 2. Clinical studies: occurrence and significance]. Endometrial cysts were found in 11 (13.4%) of 82 mares of various breeds by clinical examinations. Endometrial cysts were diagnosed by hysteroscopy and ultrasonic echography. Typical images are described. The importance of endometrial cysts is discussed with regard to differential diagnosis of early pregnancy and uterine pathology. There was no evidence of cysts in mares under 10 years of age. Mares with endometrial cysts had a 10% higher history of disturbed fertility than mares without endometrial cysts. Seven of nine mares with cystic structures in the uterus became pregnant. Endometrial cy...
Techniques for taking a behavioral history. A thorough behavioral history is essential for adequate assessment of a given case. In reviewing the chief complaint, a description of what actually happened, rather than the owner's interpretation of what happened, is required. Other behavior problems, environment, rearing history, and training need to be reviewed. Sample question sets for some common problems are given.
Restraint. The object of restraint is to limit, restrict, and keep under control the animal's movement while performing different procedures. The author discusses the importance of evaluating the horse and its owner prior to employing any type of restraint, various concepts of restraint, and examples of situations in which restraint may be required.
Arthroscopic landmarks of the equine carpus. The radiocarpal and middle carpal joints of 4 clinically normal horses and 24 necropsy specimens were examined with an arthroscope to describe the topographic anatomy of these joints. The carpal bones of the radiocarpal joint had congruent articular surfaces in extension, but carpal flexion resulted in a stairstep between the radial and intermediate carpal bones. The variable surface anatomy, as well as the restricted synovial space and the technical limitations of the arthroscope, contributed to the need for more than one arthroscopic approach to the radiocarpal joint to ensure a thorough exa...
Attempted transmission of Ehrlichia risticii by field-captured Dermacentor variabilis (Acari: Ixodidae). The capability of field-collected American dog ticks, Dermacentor variabilis, to infect horses with Ehrlichia risticii, causative agent of Potomac horse fever (PHF), was examined by allowing adult ticks collected from horse farms with a history of PHF to feed on susceptible horses. More than 500 male and female ticks attached and fed on 3 test horses; however, no clinical or serologic evidence of PHF was observed in treated or control horses. All horses were challenge exposed with E risticii-infective blood by inoculation at 60 to 65 days after ticks fed, and all developed clinical PHF with su...
Osteochondrosis-like lesion of the anconeal process in two horses. A suspected lesion of osteochondrosis dissecans involving the anconeal process of the humeroradial joint (elbow) was found in 2 horses. In horse 1, the lesion was found during routine lameness examination, during which alleviation of the lameness was achieved after intra-articular anesthesia of the elbow. In horse 2, the lesion was found at necropsy. Horse 1 responded satisfactorily to intra-articular treatment with hyaluronic acid. Both horses also had other joints affected with osteochondrosis dissecans.
Factors for prognostic use in equine obstructive small intestinal disease. Twenty horses with small intestinal obstructions requiring surgery were evaluated prospectively. Ten horses lived (group 1) and 10 died (group 2). Eight of the horses in group 1 had simple obstruction and 7 of the horses in group 2 had strangulation obstruction. There was a significant difference (P less than 0.001) between the mean intraluminal hydrostatic pressure in horses of groups 1 and 2 (6.3 cm H2O and 15 cm H2O, respectively). The mean peritoneal fluid protein concentration in horses of groups 1 and 2 (2.8 mg/dl and 5.4 mg/dl, respectively) also differed significantly between groups (P...
Recovery and evaluation of embryos from normal and infertile mares. To evaluate embryo transfer as a possible method to circumvent infertility in mares, embryos from 14 normal and 14 infertile mares were collected three times and examined. Fewer flushes (p less than 0.05) from normal than infertile mares (1/42 vs 9/42) contained only abnormal embryos whereas more flushes (p less than 0.05) from normal than infertile mares contained one or more normal embryos (28/42 vs 8/42). More flushes (p less than 0.05) from normal than infertile mares contained embryos (29/42 vs 17/42). The embryo diameters (mm) at either day-7 or day-8 post ovulation were greater (p less ...
Clinical course of renal adenocarcinoma associated with hypercupraemia in a horse. A four-year-old shire mare with haematuria, colic, terminal weight loss and an abdominal mass had a large unilateral renal adenocarcinoma. Clinical signs were monitored for 11 months. Increased serum copper concentrations were measured on two occasions. Hypercupraemia is discussed as a possible paraneoplastic change.
