Prevention of equine herpesvirus myeloencephalopathy – Is heparin a novel option? A case report. Equine herpesvirus myeloencephalopathy (EHM) is a severe manifestation of equine herpesvirus 1 (EHV-1) infection. Prevention and treatment of EHM during EHV-1 outbreaks is critical, but no reliable and tested specific medication is available. Due to the thromboischemic nature of EHM and due to the fact that EHV-1 entry in cells is blocked by heparin, it was hypothesized that this compound may be useful in reduction of EHM incidence and severity. Therefore, during an acute EHV-1 outbreak with the neuropathogenic G/D Pol variant, metaphylactic treatment with heparin to prevent EHM was initiated....
High resolution imaging of the equine cornea using the DUB®-SkinScanner v3.9. The aim was to describe the use of the DUB®-SkinScanner v3.9 (taberna pro medicum GmbH, Lueneburg, Germany) for the examination of the equine cornea. Methods: Using the DUB®-SkinScanner v3.9 various pathological corneal conditions were pictured in the A- and B-mode at a frequency of 22 and/or 50 MHz in nine eyes of eight horses. Scans were obtained from standing horses or from horses under general anesthesia non-related to image acquisition. Results: The examination allowed real time imaging and measurement of the equine cornea in vivo. Compared to slit-lamp biomicroscopy additional informa...
[Catheter-associated complications in the horse – diagnosis and treatment in practice]. Venous diseases due to venous catheters have variable symptoms and clinical progress. They comprise perivenous hematoma, periphlebitis, endophlebitis, phlebothrombosis or septic thrombophlebitis. To diagnose venous disease, a clinical examination (possibillity to distend the vein, swelling, pain, increased skin temperature, and any exudation around the injection site) and an ultrasonographic examination (perivenous tissue, venous wall, venous content) of the vein are performed. Treatment of venous diseases depends on the etiology and pathogenesis and combines the use of anticoagulants (heparin...

The reference ranges were calculated according to the Guideline EP28-A3C of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) from 2010. Results: The determined intraday precision for insulin was 3.28%, for ACTH 3...
Relationship between uterine biopsy score, endometrial infection and inflammation in the mare. Endometrial biopsy score is an accepted marker of uterine health and predicted fertility, and it has been suggested that endometrial alternations are correlated with susceptibility to persistent infectious endometritis. The objective of this study was to investigate associations of endometrial biopsy score with: 1) presence of polymorphonuclear cells (PMNs) in the epithelium and stratum compactum in histopathology; 2) presence of PMNs in cytology and 3) presence of infection in microbiology. Methods: The material for examination was collected from 69 mares suspected for subclinical endometriti...
[Clinical anatomy of the horse: teeth and dentition]. The routine inspection of the equine oral cavity allows a numerical assessment of the teeth and provides information about positional changes within the dentition. By use of appropriate dental equipment, the occlusal surfaces of all teeth can be inspected and diagnosed. However, neither the teeth nor their occlusal surfaces are constant structures. Instead, equine teeth and, in particular, their occlusal surfaces are subjected to continuous morphological and positional changes due to the effects of aging and the equine-specific high amount of occlusal wear. Therefore, it is mandatory to define...
[Comparison of the findings of rectal examination and ultrasonographic findings in horses with colic]. The examination of patients suffering from an acute abdomen routinely comprises both clinical and rectal examinations, and is ever more frequently accompanied by an ultrasonographic abdominal examination. The aim of the study was to compare the findings as defined through rectal examination with the results of the ultrasonographic examination for different forms of colic. Methods: In a retrospective study, the patient records of the Large Animal Clinic of the University of Leipzig from 2012 and 2013 were analysed, and those of horses suffering from colic were included. Diagnoses made through r...
[Yellow oat grass intoxication in horses: Pitfalls by producing hay from extensive landscapes? A case report]. Vitamin-D intoxication by yellow oat grass is often reported under the syndrome of enzootic calcinosis in ruminants in the upper regions of the Alps. The intake of Trisetum flavescens in ruminants and horses induces calcification of soft tissue, including vessels, tendons and ligaments, lung, heart and kidneys. Clinical symptoms, including a reluctance to move, inappetence, body-weight loss and impaired organ function, are frequently observed. To date, there are only a very few case reports about yellow-oat-grass intoxication in horses. The present case report describes Vitamin-D intoxication ...
[Death of two mares with retained fetal membranes]. Retained fetal membranes in mares is a relative frequent disease which can lead to severe complications. Two case studies are described in which mares died acutely despite intensive care. Pathological examination confirmed severe hemorrhage as the cause of death in both animals.
[New drugs for horses and production animals in 2014]. In 2014, no new active pharmaceutical ingredients were released on the German market for horses and food producing animals. One established veterinary active pharmaceutical ingredient is avaibable for an additional species. The analgetic buprenorphine (Buprenodale® Multidose) has additionally been authorized for horses. Furthermore, four new preparations with a new pharmaceutical form, one drug with a new formulation, new galenics and a new indication, respectively, have recently been released to the market. Furthermore, the prostaglandin F2α analoque luprostiol is available again.
[Incidence of puerperal diseases during the first 10 days after foaling in the mare]. The aim of this study was to evaluate the frequency of puerperal diseases in breeding mares in the first 10 days after birth by analysing patient data. Methods: In a university clinic patient data of 308 breeding mares with puerperal disorders which presented within the first 10 days postpartum were evaluated over a period of 10 years. A distinction was made between diseases which were able to be diagnosed at the first examination and diseases which developed during the patient's stay in the clinic. Results: A total of 21 diseases were diagnosed, with a retained placenta, lochiometra and injur...
Paroxysmal atrial fibrillation and clinically reversible cor pulmonale in a horse with complicated recurrent airway obstruction. Cor pulmonale is considered an uncommon complication in horses with recurrent airway obstruction (RAO). This case report describes the history, clinical and further examination findings, treatment, progression and outcome of a horse diagnosed with cor pulmonale and paroxysmal atrial fibrillation of 2 days duration due to a severe exacerbation of RAO. To our best knowledge, this is the first report of RAO induced pulmonary hypertension in a horse causing atrial fibrillation. However, even severe cardiac changes due to respiratory dysfunction seem to be largely reversible in horses.
Influence of cryopreservation and mechanical stimulation on equine Autologous Conditioned Plasma (ACP®). To determine the influence of cryopreservation at two different temperatures on platelet concentration, growth factor (GF) levels and platelet activation parameters in equine ACP®; moreover, to determine if adding mechanical ACP® stimulation to freeze-thaw activation amplifies GF release from platelets. Methods: Firstly, blood from five horses was used to prepare ACP®. Platelet, platelet derived growth factor BB (PDGF-BB) and transforming growth factor β1 (TGF-β1) concentrations as well as mean platelet volume (MPV) and mean platelet component (MPC) were determined in fresh and correspond...
[Alimentary intake of opioid alkaloids by horses. Hazards due to poppy-containing feeds]. Opioid alkaloids were identified in the urine of horses during an anti-doping control and in a case of intoxication. In both cases, it was suspected that the horses had ingested poppy-contaminated feed. To verify this suspicion, possible opioid alkaloid sources in Germany were identified through a literature research. Additionally, the contaminated feed was botanically and chemically analysed. The results indicated that both cases were most probably caused by the poppy in the feed. This highlights the previously underestimated risk of an intake of poppy-contaminated feed in horses. Recommendat...
[Equine leukaemic lymphoma–a rare form of equine lymphoma]. Equine leukaemic lymphoma is a rare disease of the haematopoetic tissue. It results from neoplastic degradation of B- and T-lymphocytes and their occurrence in the blood. Clinical signs are often unspecific and include chronic weight loss, ventral oedema at the thorax and abdomen and regional lymphadenopathy. Horses are often presented late in the course of the disease and therapy is rarely successful. This review summarizes the clinical pathologic findings of equine leukaemic lymphoma and the findings of laboratory testing and other diagnostic measures, and presents treatment options describe...
[Energy intake and body weight development of Warmblood foals that changed stud at weaning]. This study investigated the energy requirements of Warmblood foals with a change of the stud at weaning. Methods: Nine colts purchased at weaning participated in the study aged approximately 6Â months to 1Â year. They were transported to the stud by their breeders either having been separated from their dams in their home stable or upon arrival at the stud. The foals were offered a late first cut of haylage, oats and foal starter feed. To ensure individual feeding of concentrates, the foals were tethered twice daily. The total combined haylage intake of all foals per day was recorded. Individu...

All horses underwent clinical examination, conventional echocardiography (including cardiac output measurement at the pulmonary artery), repeated noninvasive blood pressure measurement a...
[Influence of atracurium on cardiovascular parameters in horses undergoing vitrectomy during general anaesthesia, and on recovery duration and quality]. In most ocular procedures, a central position of the eye is necessary. This can be achieved using a deep plane of anaesthesia, locoregional blocks or with neuromuscular blocking agents. The aim of this study was to evaluate the influence of atracurium on cardiovascular parameters, and on recovery quality and duration in horses. Methods: Thirty-four warmblood horses undergoing in total 50 vitrectomies were divided into two groups. Premedication, induction and maintenance were identical in all patients. After 20 minutes, horses of group A received atracurium (0.1 mg/kg) while in the control grou...
[Comparison of different electrocardiographic techniques for the detection of arrhythmias in horses]. The aim of the study was to extend the range of the electrocardiographic examination in horses, evaluating the practicability of special electrocardiographic techniques (exercise- and Holter-ECG) and comparing these with more common techniques (resting-ECG) in equine medicine. Methods: Electrocardiographic examination (resting-ECG for 1 minute, exercise-ECG and Holter-ECG) was performed in 20 horses without any clinical or echocardiographic findings and in 80 patients with abnormal findings (valvular regurgitation and/or atrial fibrillation). Results: In comparison with the resting-ECG, the ex...
[Nutritional laminitis–preventive measures for the obese horse]. Nutrition-induced laminitis is often caused by i) fermentation of large amounts of carbohydrates in the hindgut (usually fructans from grass or starch from cereals), which cause the release and absorption of microbial toxins and ii) insulin resistance induced by being overweight (equine metabolic syndrome). Both causes can act together. Overweight horses with a history of laminitis need to reduce body weight to prevent further incidences of laminitis. Weight reduction occurs normally on a diet of late-cut hay, a hay-straw mixture (maximally one third straw to prevent constipation) or grass see...

The aim of this study was to evaluate factors affecting pregnancy rates in the German Thoroughbred Breed with particular emphasis on optimisation of fertility rates for breeding stallions of older ages. Methods: Data from the studbooks of the German Thoroughbred Breeding Association from 1996 to 2009 analysed. This analysis included the records of 319 stallions and 6622 brood mares, resulting in 21,372 pregnancies at the end of the season. Results: Pregnancy rates were significantly affected by the age of the stallion and mare as well as the season (month in the breeding season in which coveri...
[Examination of horses with acute colic – clinical pathology and diagnostic imaging]. The article summarizes the relevant clinical pathological assessment of horses with acute colic. A minimal laboratory evaluation should include the patient's haematocrit (or packed cell volume), total protein, and lactate concentration in the blood. Haematocrit and total protein provide an indication of the severity of dehydration (haematocrit <Â 0.45 l/l is evidence of no to mild dehydration whereas > 0.5 l/l points to a severe dehydration). The degree of dehydration is often associated with the severity of the colic. Additionally, the blood lactate concentration rises with increasing intesti...
Unilateral cerebellar hypoplasia and mesencephalic malformation in a Hanoverian foal. Neurological cases, especially in foals, are rare in the daily practical work. The most common causes are traumata and infectious diseases of the central nervous system (CNS). This case report provides further insights into the wide spectrum of possible neuropathological lesions by detailing a complex malformation with unilateral neurological signs that occurred later post natum. Thus, clinicians should also be aware of malformations in case of respective neurological patients. A Hanoverian foal was presented with progressive ataxia. General and blood examination revealed no further alteration...
