Megaesophagus in the horse. A short review of the literature and 18 own cases. After giving a descriptive definition of megaesophagus attention is paid to the occurrence, the possible causes and pathogeneses, the clinical history and diagnosis, age, breed and sex of the horses with megaesophagus, and the prognosis. The most important characteristics of megaesophagus are summarized in two tables referring to 11 cases published in the literature and 18 own cases. Finally some conclusions based on published as well as not published own cases are given.
Epidural anesthesia and analgesia in horses. Intercoccygeal, or caudal, epidural injection of local anesthetics is a convenient method of producing analgesia and local anesthesia of the tail and perineal structures in conscious standing horses. This technique has been further developed to provide long duration analgesia and anesthesia by placement of catheters into the epidural space of horses. More recently, opioid, alpha-2 adrenergic agonists, ketamine and other analgesic agents have been administered by caudal epidural injection, providing pain relief in both conscious, standing and anesthetized, recumbent horses. This chapter describ...
Allometric respiration/body mass data for animals to be used for estimates of inhalation toxicity to young adult humans. The relationship between body weight (BW) and respiratory minute volume (V(m)) was reviewed by collecting a database from the literature. The data were separated into anaesthetized and non-anaesthetized groups. Only young adult terrestrial mammals were included in the final data set. This database is the largest to be reported to date, is the first to separate the anaesthetized and non-anaesthetized groups and is matched to the target population of young, fit adult humans. The data set of non-anaesthetized animals contained 142 studies representing 2616 animals and 18 species from mice at 12 g...
Towards an understanding of equine pleuropneumonia: factors relevant for control. To review relevant literature on factors associated with the development of equine pleuropneumonia. Methods: A review of the literature using a range of databases including Current Contents, Medline, ChemAbstracts, Biological Abstracts and CAB and a comprehensive search strategy which involved use of keywords, author and subject category searches. Additional sources included review of articles cited by key accumulated references. Results: Since the early years of this century, many of the "gaps" in our knowledge of the pathogenesis of this disease have been filled. We now know that equine pleu...
Equine nasal and paranasal sinus tumours. Part 1: review of the literature and tumour classification. The normal gross and histological anatomy of the equine nasal and paranasal sinuses are reviewed and the relationships between the local anatomy, the occurrence of different tumour types, and of tumour spread are examined. The histological classification of the more common equine sinonasal tumours and tumour-like lesions are discussed. Clinical and pathological descriptions of 50 more recently recorded such tumours are separately tabulated. The literature shows that equine sinonasal tumours, both endemic and sporadic, are relatively uncommon in horses, with non-neoplastic growths such as maxil...
Aetiopathogenesis of parasagittal fractures of the distal condyles of the third metacarpal and third metatarsal bones–review of the literature. Fractures are the cause of considerable morbidity and mortality among Thoroughbred racehorses. A significant proportion of these injuries occur in the absence of any particular traumatic incident. Evidence of prefracture pathology interpreted as fatigue damage has been identified in some such cases, but the aetiology of many of these so-called 'spontaneous' fractures remains obscure. Parasagittal fractures of the third metacarpal (McIII) and third metatarsal (MtIII) bones are one of the more common fractures to affect Thoroughbred racehorses. The configuration of each of these fracture types i...
[Application possibilities of laser surgery in veterinary medicine. 3: Literature review and some case reports]. The transmission of the laser beam trough flexible fibers enables an endoscopic application. Since this technique is minimal invasive and often does not require general anaesthesia there is an increasing interest in the use of laser techniques-for example in equine upper respiratory tract surgery. This paper gives a review about reported laser application in the different fields of veterinary surgery with emphasis on laser practice in dermatology, ophthalmology and endoscopic laser application.
[Natural and synthetic glucocorticoids in the racing horse: a review of the literature]. This review compromises data about endogenous cortisol and its physiological variations in horses. The influence of synthetic glucocorticoids on the endogenous cortisol concentrations is discussed as well. The second part of the review summarizes detection times of therapeutically used glucocorticoids (dexamethasone, betamethasone, triamcinolone, prednisone, prednisolone, methylprednisolone and hydrocortisone) in the horse and their implication for doping control.

Interaction of beta-lactoglobulin with retinol and fatty acids and its role as a possible biological function for this protein: a review. beta-Lactoglobulin is the major whey protein in the milk of ruminants and some nonruminants, such as pigs and horses. Although beta-lactoglobulin was first isolated 60 yr ago, no function has been definitely ascribed to beta-lactoglobulin. Recent x-ray crystallographic studies have advanced knowledge of the structure of beta-lactoglobulin, which is homologous with that of retinol-binding protein and lipocalycins; the function of these proteins seems to be participation in the transport of small hydrophobic substances. By analogy, this protein has been suggested as having a role as a transporte...
The function of the equine carpal joint: a review. The most consistent published ideas on the function of the carpal joint of the horse concern the elasticity of the joint, and its limits to extension. Most of these are not well substantiated experimentally. Compression stress appears to be absorbed by the intercarpal ligaments as the carpal bones are separated by a wedge action during loading. Overextension is prevented by occlusion of dorsally located stop facets on the rows of carpal bones, and by the support of a stay apparatus.
The molecular weight of therapeutic hyaluronan (sodium hyaluronate): how significant is it? Various molecular weight hyaluronic acid (HA) preparations have been injected into joints for the treatment of human and equine osteoarthritis. A therapeutic advantage has been claimed for commercial products with a molecular weight in the range found in normal synovial fluid (SF), compared to lower molecular weight products. But a correlation between molecular weight and efficacy is not borne out by an analysis of the available literature on clinical results. SF viscosity, HA concentration, HA molecular weight and rate of synthesis in joint disease. It is proposed that the beneficial effect o...
Review of equine Cryptosporidium infection. Diarrhoea is one of the most important diseases of foals and
7040% are affected within the first 6 months of life (Palmer
1985). Although the cause is multifactorial and changes in the
physiology and nutrition of foals are sometimes responsible,
diarrhoea is frequently the result of infection by enteropathogens
such as bacteria, viruses and nematodes (Palmer 1985; Tzipori
1985). There is increasing evidence that Cryptosporidium
infection can also cause diarrhoea in foals (Austin et a/. 1990;
Kim 1990).
Cryptosporidiosis in horses is caused by Cryptosporidium

Plasma cell myeloma in the horse. A case report and literature review. Plasma cell myelomas in horses have been reported infrequently. Data from 10 cases, 9 from the literature and 1 new case, are used to characterize the disease in the horse. Hot-blooded horses (7/10), specifically Quarter Horses (4/10), were most often affected. Median age at diagnosis was 11 years (range, 3 mo-22 yr) and both male (5) and female horses (5) were represented equally. Clinical findings included weight loss (6/8), anorexia (4/8), fever (4/8), limb edema (4/8), pneumonia (3/8), rear leg paresis/ataxia (3/8), epistaxis (3/8), palpable lymphadenopathy (2/8), and bone pain (2/8). Anem...
[The history of the book, “The family horse doctor, or the art of healing one’s own horse,” by Francis Clater]. Francis CLATER presumably was born in 1754 near Nottingham. He became farrier after years of apprenticeships at Newark and Retford. In 1783 the first edition of his book "Every man his own farrier" was published. Within 50 years at least 30 editions were printed. This book was translated by PRETOT into French (1822), by S. von TENNECKER (1823) and by LENTIN (1834) into German and by TURNE (1838) into Russian language. Contents of some editions are compared and valued.
Left cranial vena cava in a horse. A complete left cranial vena cava (LCVC) was found in a normal horse. The LCVC was well developed, but there was a complete absence of the right cranial vena cava. The azygous vein was normally distributed on the right side of the thoracic vertebral bodies but passed ventral to the aortic arch to empty into the cranial vena cava on the left close to the origin of the aortic arch. The LCVC passed over the dorsal aspect of the left atrium to reach the coronary sulcus on the caudal aspect of the heart. The LCVC opened into the right atrium via a 5 cm diameter orifice (orifice of coronary sinus). ...
[Bone marrow examination in the horse]. The technique of needle biopsy, the examination of aspirated bone marrow and the interpretation of bone marrow smears are described. The indications for a bone marrow biopsy are listed and the literature is reviewed. The significance of this examination is illustrated with some clinical cases.
Alsike clover poisoning: A review. Trifolium hybridum (alsike clover) has been implicated as the cause of two diseases of the horse. One of these is photosensitivity, of which alsike clover is only one of a number of presumed causal agents. The other is a fatal syndrome which is known as "alsike clover poisoning" and which is manifest by progressive loss of condition, signs of hepatic failure, and varying degrees of neurological impairment. The underlying lesion of alsike clover poisoning is fibrosis and proliferation of the biliary tree. The experimental evidence implicating alsike clover as the cause of this syndrome comes en...
[A comparison of suturing and non-suturing of scrotal wounds following castration in stallions]. It was found that wound infections may be considerably reduced when castration is carried out under strictly aseptic conditions. In this clinical review, healing of the wound following castration with and without closure of the scrotal wounds is compared. All castrations were performed under similar aseptic conditions, general anaesthesia having been produced in the recumbent stallion. The results do not show that there is a significant difference in the appearance of wound infections in scrotal wounds which are closed and those which are left completely open. On the basis of both papers and t...
Vascular malformations and angiomatous lesions in horses: a review of 10 cases. Vascular malformations and angiomas are rather uncommon in horses and the literature concerning these lesions is reviewed. The pathology is described in 10 additional cases. These lesions were classified as arteriovenous malformation (one case), haemangiomas (six cases), 'proliferative angiomas' (two cases) and lymphangioma (one case). The haemangiomas and lymphangioma were probably hamartomatous in origin. Both cases of 'proliferative angioma' developed in aged animals and their pathogenesis was uncertain. More information is needed on the natural history and behaviour of lesions of this type...
[Interruption of the sensory nerve tract in chronically lame horses]. Within the framework of the series 'Papers of yesterday and today', two articles on neurotomy by Moubis (1876 and 1878) are used to evaluate the present status of neurectomy. In 1800 neurotomy was replaced by neurectomy because of the reinnervation which occurred after several weeks. On the basis of a literature review and clinical experience in the Department of Large Animal Surgery the indications, conditions, anatomy, operative techniques, complications and results of neurectomy are discussed. Post-operative neuroma formation is the most important complication following palmar digital neure...
Detomidine: a new sedative for horses. Detomidine, given intravenously at doses of 5 to 30 (mean 13) micrograms/kg bodyweight (bwt), provided adequate sedation for a variety of clinical procedures in 93 per cent of administrations, and improved the ease of handling in the remaining animals. Side effects of ataxia and bradycardia were minimal at the lower dose rates. Higher doses were required for intramuscular use. In experimental trials 10 and 20 micrograms/kg bwt resulted in deep sedation and also significant hypertension and bradycardia of over 15 mins duration. Current literature on the use of detomidine in horses is reviewed.
Intestinal atresia and stenosis: a review comparing its morphology. A review of the literature on intestinal atresia of domestic animal species and humans was done. The 5 types of intestinal occlusions described in human infants are atresia type 1, atresia type 2, atresia type 3, stenosis, and the "apple peel" or "Christmas tree" deformity. The intestinal defects described in domestic animal species such as the bovine, equine and porcine are similar to those of human infants. The "T-formation", an intestinal defect of the bovine resembling atresia type 3, and rectal stricture, an acquired intestinal defect of the porcine resembling stenosis, were described rec...
