Topic:Veterinary Practice
Veterinary practice in relation to horses encompasses the medical care, management, and treatment of equine species. This field involves various aspects of equine health, including preventive care, diagnosis, and treatment of diseases, surgical interventions, and emergency care. Equine veterinarians employ a range of diagnostic tools and techniques such as physical examinations, imaging, and laboratory tests to assess and monitor horse health. In addition to addressing physical ailments, veterinary practice also includes nutritional management, reproductive health, and performance-related issues. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, advancements, and outcomes in veterinary practices specific to equine health.
Evidence for non-siderophore-mediated acquisition of transferrin-bound iron by Pasteurella multocida. Two clinical isolates of Pasteurella multocida associated with bovine pneumonia were examined for iron acquisition. Both isolates were capable of obtaining iron for growth from bovine but not from human, avian, equine or porcine transferrin. This correlated with specific binding of bovine transferrin by iron-limited cells or isolated membranes. No siderophore was detected in the strains by a general screening assay. In response to iron-limited conditions, a number of high molecular mass iron-regulated outer membrane proteins were produced including an 82 kDa receptor protein which was affinity...
Use of phenytoin to treat horses with Australian stringhalt. Five horses with Australian stringhalt were treated with 15 mg/kg phenytoin orally for 2 weeks. During the second week of the trial, 3 of the horses were given an additional dose of 10 mg/kg phenytoin. The response to treatment was clinically assessed by grading the severity of the gait abnormality at the walk, trot, turning and backing twice daily. There was a significant (P less than 0.05) improvement in the gait abnormality when pre-treatment values were compared with the mean of the last 3 assessments before treatment stopped. When reassessed 2 weeks after treatment ceased, there remained ...
Clinical relevance of radiographic findings in proximal sesamoid bones of two-year-old standardbreds in their first year of race training. Radiographs of all 4 fetlocks of 71 Standardbred racehorses were obtained at 3-month intervals for 1 year. Radiographic findings in the abaxial surface of the proximal sesamoid bones were classified into 3 types according to the severity of lesions, and correlation was made with clinical findings at time of examination. Type-1 lesions (1 or 2 linear defects less than or equal to 1 mm wide) were detected in 55% of horses at the start of training; clinical signs of disease were not manifested, and lesions did not become clinically relevant. Type-2 lesions (3 or more linear defects less than or e...
Eltenac, a new anti-inflammatory and analgesic drug for horses: clinical aspects. Two controlled studies to determine efficacy in the horse were performed with eltenac, a new injectable, non-steroidal anti-inflammatory drug (NSAID). Clinical trials were carried out with a dose rate of 1 mg/kg body weight in a randomized, placebo-controlled, double-blind design to assess therapeutic efficacy in acute inflammatory disorders and in animals with orthopaedic conditions. In a preliminary pharmacokinetic investigation in six horses mean elimination half-life was 1.7 h after i.v. administration. In the first clinical study, analgesic activity on pain-related lameness was determined...
Head trauma in two horses. The initial clinical signs displayed by two horses with head trauma are described and related to the pathology and management of the condition, to illustrate the diversity of signs that may result from similar events. It is suggested that careful repeated neurological investigations are more reliable prognostic indicators in cases of equine head trauma than a reliance on the initial assessment.
Use of phacofragmentation for cataract removal in horses: 12 cases (1985-1989). The medical records of 12 horses that had cataracts removed by use of phacofragmentation were reviewed. Cataracts were removed from 16 eyes in horses ranging in age from 2 months to 15 years. Complications after surgery included corneal ulcers in 13 eyes, diffuse corneal edema in 5 eyes, and uncontrollable uveitis in 3 eyes. Follow-up information was obtained in all horses from 1 month to 3.5 years after surgery. Visual results were judged good by owners or veterinarians in 10 of the horses.
[The effectiveness of therapeutic horseback-riding in the treatment of chronic schizophrenic patients. Experimental results and clinical experiences]. After describing horse-riding as a facility in managing mentally ill patients, a program for chronic schizophrenic in-patients is presented. Clinical experience with this program and also results of a controlled study are reported. The therapeutic value and slope for horse-riding are discussed in relation to different diagnoses.
Ultrasonographic detection of chronic epididymitis in a stallion. Clinical signs of chronic epididymitis in a stallion included recurrent signs of inguinal pain--retraction of the right testis into the inguinal area, resentment of palpation of the right testis, and right-sided scrotal swelling. The tail of the right epididymis was firm and seemed to be adhered to the testis. The tail of the left epididymis felt firmer than normal. Ultrasonographically, the diameter of the head of the epididymis was considered larger than normal, was hyperechoic in relation to the right testis, and had an irregular border. Several bright 1- to 5-mm-diameter echogenic areas th...
[A method for the quantification of estrus symptoms in mares]. As part of the veterinary surveillance of horse breeding management, the veterinarian is increasingly often requested to predict ovulation and to give a breeding or insemination advice accordingly. The result of a teasing procedure is indispensable for this advice. A suggestion is made for the quantification of oestrus signs. Oestrus symptoms are classified into four categories. In addition, various factors are mentioned, which affect the result of a teasing procedure.
Additional diagnostic procedures. This article reviews recent diagnostic procedures that have arisen over the last 10 years. Videoendoscopy of horses on a high-speed treadmill allows observation of some of the changes that take place in a horse's airway during exercise. Measurements of upper airway airflows and transupper airway pressure, the use of an esophageal balloon and a Ventigraph to measure changes in pleural pressure, and pulmonary function testing are new techniques that aid the researcher in understanding the mechanics and pathologic characteristics of airway diseases and help the practitioner in assessing the sever...
Prognostic features and clinical presentation of acute idiopathic enterocolitis in horses. Clinical and hematological changes observed on presentation of 47 horses referred to the Ontario Veterinary College with acute idiopathic colitis were analyzed for their prognostic features. Cases of acute enterocolitis were characterized by fever, dehydration, abnormalities of serum electrolyte concentrations, azotemia, hypoalbuminemia, and increased serum concentrations of muscle enzymes. Severely dehydrated horses were seven times more likely to die or be euthanized than those that were not dehydrated. Other factors associated with failure to survive included the following: increased hemato...
[The fully-automatic analytic system Vision in horse practice in comparison with Compur M 2000 CS]. We describe the utilization of the Abbott Vision system in a horse clinic and a comparison with the Compur M 2000 CS (Bayer Diagnostics and Electronics). Discrepancies were found in respect to precision and accuracy of results. Both systems showed good practicability during routine operation but different cost-effectiveness.
Application of lasers in equine upper respiratory surgery. The advantages and disadvantages of various surgical lasers are discussed. Included are aspects of laser safety, anesthesia and analgesia considerations for laser surgery, and diagnostic considerations. Horses with lesions such as ethmoid hematomas, nasal polyps, and lymphoid masses are ideal candidates for laser treatment. Other conditions that are suitably treated with lasers, such as dorsal displacement of the soft palate and entrapment of the epiglottis, are described.
Clinical use of metronidazole in horses: 200 cases (1984-1989). Case records of 200 horses treated with metronidazole were reviewed. Horses were treated for respiratory tract infections (90 cases), peritonitis or abdominal abscess (39 cases), celiotomy (49 cases), orthopedic infections (6 cases), and miscellaneous soft tissue infections (16 cases). Bacteria of the genus Bacteroides were most prevalent (55 of 167 anaerobic isolates). Metronidazole was always used in combination with other antimicrobial drugs. Only 4 of the 200 horses had signs of adverse effects associated with metronidazole treatment. Those 4 horses had poor appetite that resolved when met...
Contribution of delta bilirubin to the interpretation of hyperbilirubinemia in the horse – a pilot study. A study was conducted to examine the relationship of delta bilirubin to traditional bilirubin fractions to determine if delta bilirubin might assist in differentiating causes of hyperbilirubinemia in the horse. A recently introduced thin-film method was used for delta bilirubin determination. Thin-film and the traditional diazo methods were used for determining total, unconjugated, and conjugated bilirubin fractions. Sera from 38 healthy and 85 sick horses were examined.Thin-film serum delta bilirubin determination does not appear to assist in differentiating causes of unconjugated hyperbiliru...
Clinical relevance of monocyte procoagulant activity in horses with colic. Endotoxin-activated monocytes express a thromboplastin-like procoagulant activity on the cell surface that may serve as a focal point for formation of microvascular thrombi. Because coagulopathy is a common sequela to endotoxemia in the equine species, we investigated the ability of monocytes, isolated from horses with colic, to express procoagulant activity. On the day of admission, and on the third and fifth day of hospitalization, monocytes were isolated from 30 adult horses with colic. A coagulation profile, including prothrombin time, activated partial thromboplastin time, thrombin time, ...
Identification of 15- to 17-kilodalton antigens associated with virulent Rhodococcus equi. Antigens of Rhodococcus equi were analyzed by immunoblotting with naturally infected foal sera. Immunoblots of whole-cell antigen preparations of clinical isolates of R. equi revealed that major protein bands with molecular masses of 15 to 17 kDa were present in all clinical isolates tested and all isolates virulent for mice. In contrast, the 15- to 17-kDa antigens were not identified by immunoblotting in ATCC 6939, a type strain of R. equi that was avirulent for mice. Whole-cell antigens of 102 environmental isolates were investigated by immunoblotting and the mouse pathogenicity test. Twenty...
Modification of the cutting thread technique for intestinal anastomoses using diathermy. The author has modified a surgical technique, which was originally developed at the turn of the century, for the aseptic establishment of an intestinal anastomosis. The principle of this technique, known as the "cutting thread" principle, was that a loop of thread was introduced into the lumen of each of two approximated loops of intestine. After suturing the two loops of intestine together around the intraluminal parts of the thread, the latter was used as a "wire-saw" to create a stoma between the two intestinal loops. The author modified the method in such a way that the cutting could be pe...
Use of gastrotomy to relieve esophageal obstruction in a horse. Esophageal obstruction of 1 week's duration in a gelding was diagnosed by contrast radiography and esophagoscopy. A food bolus was found at the junction of the caudal thoracic portion of the esophagus and the cardia. A gastrotomy was performed through a cranial abdominal incision and a phytobezoar was manually broken down and removed. The gelding was started on complete pellet food and water on the fifth day after surgery. The horse remained clinically normal more than 1 year after surgery.
[The horse as an aid in therapy]. Physiotherapy on the back of the moved horse has two important dimensions: 1) The somatotropic effect regards mainly spasticity, ataxia, the vertebral column, the basis of the pelvis and the skin. 2) A general psychotherapeutic and psychohygienic effect is created by joy, change and new impetus in rehabilitation and by the emotional contact with the "comrade animal". Or unit was the first to introduce hippotherapy with adults in Austria. There is specially good experience with the spastic atactic component in multiple sclerosis. However other diagnosis as well showed good profit, such as strok...
Effects of furosemide on ponies with recurrent airway obstruction. The effect of aerosol and intravenous administrations of furosemide was examined in ponies with recurrent obstructive pulmonary disease, commonly called 'heaves'. This recurrent airway disease bears many similarities to human asthma. Six ponies with the disease (principal animals) were studied during clinical remission and during an acute attack of airway obstruction precipitated by stabling and feeding dusty hay. Six control animals were also studied. Furosemide (1.0 mg/kg) or vehicle was administered by aerosol in the first study, and intravenously in a second study. In principal ponies with...
