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.
[Preliminary experience with a buffy coat analyser in horses]. The present author's practice was offered the opportunity of testing a so-called buffy-coat analyser of the firm of Becton & Dickinson for its use in the field. He does not deny readers the report of his preliminary experience. In addition, the interpretation of the results and the limitations of the apparatus are briefly discussed.
Second-intention healing. Second-intention healing (contraction and epithelization) is most appropriate for heavily traumatized, contaminated wounds that may have a prolonged debridement phase. Therapy during healing can promote rapid debridement and faster healing. Healing of lower limb wounds by second intention may be protracted, owing to poorer wound contraction and excessive granulation tissue production as compared with body wounds.
Wounds of the esophagus and trachea. Wounds of the esophagus and trachea are uncommon, but closed wounds can be difficult to diagnose and treat. Esophageal wounds are the more serious and can be life-threatening; however, appropriate surgical and medical treatment applied without delay can be successful in some cases, especially in full-thickness longitudinal wounds. Tracheal wounds are usually less severe, but the high risk of iatrogenic injuries to the trachea should be recognized. Also, tracheal injuries can limit the athletic potential of a horse.
Delayed wound closure and scar revision. Delayed closure is an underutilized technique that can produce a good cosmetic result in lower leg wounds and can significantly shorten the healing time. To be successful, the surgeon should be able to utilize tension-relieving techniques and manage dead space. Scar revision should be limited to simple elliptical excision or modifications thereof until experience is developed. Sliding skin flaps, Z-plasties, and W-plasties are used infrequently and require adequate preoperative planning.
Cytologic and bacteriologic evaluation of tracheobronchial aspirates from clinically normal foals. Thirty-eight tracheobronchial aspirates (TBA) were collected from twenty 1 to 6-month-old foals, which were free of clinical signs of respiratory tract or other infectious disease. We collected TBA from 9 of the foals 3 times when they were approximately 8, 16, and 24 weeks old. Aspirates were examined cytologically after staining with modified Wright-Giemsa, Gram, toluidine blue, and prussian blue stains. Aerobic bacterial culturing was performed on all aspirates. Of the 20 initial TBA, 4 (20%) were normal cytologically on the basis of previously defined criteria for TBA from clinically norma...
[The pattern of riding injuries]. During the period from 1.1. to 31.12.1988, 104 patients with injuries resulting from riding or other forms of direct contact with horses were examined and treated in a casualty department in the County of Vejle. Antecedent data from these patients were collected. The majority of injuries occurred on falling from the horse and involved particularly the upper part of the body. The commonest injuries were bruises which did not require special treatment. The relationships between concussion, fracture of the humerus and fracture of the clavicle and riding were investigated by odds ratio. Much fewer...
A computer-derived protocol to aid in selecting medical versus surgical treatment of horses with abdominal pain. In order to determine which variables are useful in identifying horses with abdominal pain requiring surgery, data were analysed from 219 horses presented at one veterinary teaching hospital. Using multiple stepwise discriminant analysis with a recursive partitioning algorithm, we obtained a decision tree that identifies surgical and non-surgical patients. The prevalence of surgical patients was 79 per cent in this population. The sensitivity, specificity, and positive and negative predictive values of this decision tree were 99 per cent, 55 per cent, 90 per cent and 99 per cent respectively. ...
Umbilical cord remnant abscess in a yearling colt. An abscess of the external umbilical remnant and umbilical vein remnant was diagnosed in a 16-month-old colt, using ultrasonography. Because of the colt's size, primary closure of the surgical incision after umbilical cord resection was not complete. Vertical mattress stainless steel sutures and stents were used, and healing was by second intention. Intervening gas-filled viscera made it impossible to visualize ultrasonographically the bladder of umbilical artery remnants in a colt of this age.
Controlled test and clinical evaluation of dienbendazole against naturally acquired gastrointestinal parasites in ponies. A controlled test was performed to titrate the anthelmintic dosage of dienbendazole in 24 mixed-breed ponies naturally infected with Strongylus vulgaris, S edentatus, and small strongyle species, as determined by parasitic egg and larval counts in feces. Comparison of results of treatment was made among 3 dienbendazole dosages--2.5, 5, and 10 mg/kg of body weight--and a gum (excipient) mixture given by nasogastric intubation. All ponies were euthanatized and necropsied at 7 or 8 days after treatment. Trichostrongylus axei, Habronema muscae, S vulgaris, S edentatus, small strongyles, and Oxyuri...
Technique for transrectal ultrasonography of the cranial mesenteric artery of the horse. Transrectal ultrasonography was successfully used to image the cranial mesenteric artery and its branches in 23 adult horses. The artery could be imaged from its origin at the aorta distally to identify several bifurcations. The method for transrectal imaging of the cranial mesenteric artery and its major branches required 3 distinct transducer positions. One position was used to locate the cranial mesenteric artery by imaging the caudal portion of the aorta from the aortic bifurcation cranially to the level of the cranial mesenteric artery. The second position was used to image the origin of ...
A retrospective study of nineteen ataxic horses. A retrospective study of 19 ataxic horses admitted to the College of Veterinary Medicine of the University of Montreal during the period of January 1985 to December 1988 is presented. There were 11 cases of cervical vertebral malformation, four of equine degenerative myeloencephalopathy, two of equine protozoal myeloencephalitis, one each of vertebral osteomyelitis and intervertebral disc protrusion. The clinical diagnosis of ataxia in horses requires neurological, radiographic, myelographic, and laboratory examinations.
Agenesis of the corpus callosum with cerebellar vermian hypoplasia in a foal resembling the Dandy-Walker syndrome: pre-mortem diagnosis by clinical evaluation and CT scanning. DORSAL midline dysgenesis of the human brain, a complex
pattern of maldevelopment of sulcation and neuronal migration
occurring before 74 days gestation, has been recognised for over
fifty years. The association (68 per cent) of the so-called Dandy-
Walker syndrome (cystic dilatation of the fourth ventricle and
hypoplasia of the cerebellum) with other brain malformations is
common and often includes agenesis of the corpus callosum
(Hart, Malamud and Ellis 1972; Ral et a1 1980). This report
describes the first pre-mortem identification of such a structural
brain anomaly in a Thoroughbr...
The influence of corticosteroids on sequential clinical and synovial fluid parameters in joints with acute infectious arthritis in the horse. Infectious arthritis was induced experimentally in one tarsocrural joint of six horses by intra-articular injection of 1 ml Staphylococcus aureus-saline suspension with the addition of 200 mg methylprednisolone acetate. The corresponding contralateral joint was injected with 1 ml of saline with the addition of 200 mg methylprednisolone acetate, and served as a control. The purpose of the experiment was to examine the effect of corticosteroids on the acute clinical signs of infectious arthritis, and the associated changes in synovial fluid, to separate the effects of a steroid injection from th...
Sequential clinical and synovial fluid changes associated with acute infectious arthritis in the horse. Infectious arthritis was induced experimentally in one tarsocrural joint of six horses by intra-articular injection of 1 ml Staphylococcus-saline suspension containing 9 x 10(4) to 3 x 10(6) organisms. The corresponding contralateral joint was injected with 1 ml of saline and served as a control. The progression of the induced infectious arthritis was assessed over a nine-day period by clinical examination and sequential synovial fluid analysis with pH and lactate measurements. Changes in synovial fluid were present before clinical signs of infectious arthritis were manifested. The diagnostic ...
Management of rectal injuries. Diagnosis, evaluation, and management of the various grades of rectal tears is discussed. Surgical techniques, which include direct closure, diverting colostomies, and placement of temporary rectal liners, are detailed. Also, rectal prolapses and various methods of repair are outlined.
Clinical Leptospira interrogans serogroup Australis serovar lora infection in a stud farm in The Netherlands. A Leptospira interrogans serogroup australis serovar lora infection in a stud farm is reported. During three successive years (1984-1986) clinical leptospirosis with a severe often rapid, fatal course was seen in 12 foals. Clinical examination revealed severe respiratory distress, depression and pyrexia. Other symptoms were diarrhea (2), jaundice (1), and an unsteady gait (1). Morphological characteristics of the disease were massive pulmonary haemorrhage and haemorrhagic-thrombotic or extracapillary glomerulonephritis with tubulonephrosis and interstitial oedema. In most foals high or increas...
Screening and confirmation of drugs in horse urine by using a simple column extraction procedure. A simple and reproducible column (Clean Screen-DAU, copolymeric bonded-phase silica column) extraction procedure has been described for the screening and confirmation of drugs in horse urine. The recovery of drugs by the column extraction was better than or comparable to the recovery by the liquid-liquid extraction, which is commonly used in the equine analytical laboratories. The column extraction provided broad coverage of drugs, separated extracts into three fractions (acidic/neutral, steroids, basic), produced a cleaner extract, and eliminated the need for special liquid-liquid extraction ...
Comparison of age, sex, breed, history and management in 229 horses with colic. A study, at a university in south eastern USA, aimed to determine whether age, sex, breed, management and history differed in colic cases. A detailed history was obtained for 229 horses between January 1987 and June 1988. Causes for colic determined by clinical examination, exploratory laparotomy and/or necropsy included: gastric rupture (GR, 6); ileal impaction (II, 17); small intestinal strangulating obstruction (SIO, 22); proximal enteritis (PE, 16); transient small intestinal distension (TSID, 18); large colon displacement (LCD, 52); large colon impaction (LCI, 34); colitis (8); small colo...
