ECEIM consensus statement on equine kidney disease.

The aim of this consensus statement is to summarize and appraise scientific evidence and combine this with the clinical experience of a panel of experts to optimize recommendations on how to recognize and manage kidney disease in horses.

Novel Board Game versus Active Case-Based Discussion to Teach Final-Year Veterinary Students the Diagnostic Approach to Clinical Cases.

Traditional lectures, where students listen passively, often do not reflect the complexity of real-life decision-making situations. Furthermore, modern students are using online devices for daily activities, and this has a challenging side effect for educators, as many people these days can only maintain their focus if topics are discussed in concise and engaging ways. For these reasons, there is growing interest in the use of games for educational purposes.

Do post-surgical multiresistant urinary infections occur in horses? Case of unilateral pyelonephritis caused by extended-spectrum beta-lactamase-producing bacteria as a complication of cystotomy.

Pyelonephritis is a serious condition that is rarely described in horses. In contrast, urinary tract infections are common in humans and small animals, and multi-drug-resistant urinary infections are an emerging threat. In this report, we describe a horse with unilateral pyelonephritis caused by extended-spectrum beta-lactamase-producing bacteria belonging to the Enterobacter cloacae complex.

Use of intralesional cisplatin to successfully treat distal limb haemangiosarcoma in a foal.

A 4-month old, 200 kg, grey warmblood colt presented for a firm, non painful mass on the distal medial aspect of the left third metatarsus. Excisional biopsy revealed a diagnosis of haemangiosarcoma. Equine haemangiosarcoma is uncommon and only limited reports of successful treatment are available.

Biomarkers of Kidney Disease in Horses: A Review of the Current Literature.

Creatinine only allows detection of kidney disease when 60 to 75% of the glomerular function is lost and is therefore not an ideal marker of disease. Additional biomarkers could be beneficial to assess kidney function and disease. The objectives are to describe new equine kidney biomarkers.

Equine Suture Exostosis: A Review of Cases from a Multicenter Retrospective Study.

Suture exostosis is an intriguing and not uncommon pathology that has to be included in the differential diagnosis for horses with swelling of the head. Although several singular case reports have been published, no large case series is available. The aim of this study is to report a multicentric retrospective collection of suture exostosis cases.

High ambient temperature and humidity associated with early embryonic loss after embryo transfer in mares.

Increased ambient temperatures has been identified to contribute to reproductive outcomes for several domesticated species, but its impact on equine reproduction has not been previously investigated. Therefore, this study aimed to examine the relationship between ambient climatic conditions, as measured by temperature-humidity index (THI) between day 7 and day 14 of gestation, and early embryonic loss (EEL) in recipient mares undergoing embryo transfer. The study examined records from 834 embryo transfers at an equine breeding facility in Victoria, Australia.

Chlamydia psittaci: a suspected cause of reproductive loss in three Victorian horses.

Chlamydia psittaci was detected by PCR in the lung and equine foetal membranes of two aborted equine foetuses and one weak foal from two different studs in Victoria, Australia. The abortions occurred in September 2019 in two mares sharing a paddock northeast of Melbourne. The weak foal was born in October 2019 in a similar geographical region and died soon after birth despite receiving veterinary care.

Targeting epigenetic nuclear reprogramming in aggregated cloned equine embryos.

Epigenetic perturbations during the reprogramming process have been described as the primary cause of the low efficiency of somatic cell nuclear transfer (SCNT). In this study, we tested three strategies targeting nuclear reprogramming to investigate effects on equine SCNT. First, we evaluated the effect of treating somatic cells with chetomin, a fungal secondary metabolite reported to inhibit the trimethylation on histone 3 lysine 9 (H3K9 me3).

Fetal Membrane Removal in the Mare: Proactive Versus Reactive Approaches.

Retained fetal membranes are the most common postpartum condition in mares. Although the incidence of retained fetal membranes is low, the consequences for the health of the mare can be severe (metritis, endotoxemia, laminitis, death). Oxytocin administration is often the first line of therapy for management of retained fetal membranes.

Clinician attitudes to pain and use of analgesia in cattle: where are we 10 years on?

Pain in cattle can arise though disease or injury or may result from veterinary or husbandry procedures. Controlling pain is important to safeguard animal welfare. Previous studies indicated that the use of analgesics in cattle has lagged behind use in companion animals.

Transurethral removal of a cystic urolith in a mare using a laparoscopic specimen pouch.

Case Report: Cystic urolithiasis is the most common form of urolithiasis reported in horses. In contrast to the gelding or stallion, clinical disease is less common in the mare and manual removal techniques are possible because of their shorter, wider urethral anatomy. However, these manual removal techniques can be traumatic and are limited by the size of the urolith.

Comparative efficacy of BioRelease Deslorelin® injection for induction of ovulation in oestrus mares: a field study.

Objective: To investigate the comparative efficacy of BioRelease Deslorelin® (BRD) and Ovuplant® for induction of ovulation in cyclic mares in Australia.

Methods: Ovarian follicular activity of 60 mares for a total of 95 cycles was monitored by ultrasonography until they developed a follicle ≥30 mm and a uterine oedema pattern of 3. Mares were then randomly allocated to one of three treatment groups: (1) treatment with 1.

Hyponatraemic encephalopathy in azotaemic neonatal foals: four cases.

Case Series: Four neonatal foals were presented, over a 2-year period, (2011-2012) with aimlessly walking, head pressing, 'chewing gum' seizures and ataxia. The neurological lesion was consistent with increased intracranial pressure in all cases. All foals had severe hyponatraemia and azotaemia identified on biochemistry.

Treatment of osteochondrosis dissecans in the stifle and tarsus of juvenile thoroughbred horses.

Objectives: To determine if arthroscopic surgery performed on weanlings/yearlings with trochlear ridge OCD of the femur (stifle OCD), or intermediate ridge of the tibia (tarsal OCD) detected on routine presale radiographs affects future racing performance.

Study Design: Retrospective case control study.

Animals: Thoroughbred weanlings and yearlings.

Use of ultrasound-guided autologous bone marrow transfer for treatment of suspensory ligament desmitis in 30 race horses (2003-2010).

Objective: To evaluate the racing performance of horses that underwent ultrasound-guided intralesional injection of autologous bone marrow aspirate for treatment of selected forelimb suspensory ligament (body or branch) core lesions.

Design: Retrospective cohort study of 13 Standardbred and 17 Thoroughbred race horses.

Methods: Autologous bone marrow aspirated from the sternebrae was injected, under ultrasound guidance, into suspensory ligament core lesions (body or branch).

Surgical treatment of septic physitis in 17 foals.

Objective: To document the progression and outcome after surgical curettage of septic physes in foals.

Study Design: Case series of 17 foals, aged <9 weeks, with septic physitis.

Methods: All foals were treated surgically with curettage of physeal lesions.

Methiocarb poisoning of a horse in Australia.

Snail bait poisoning is rare in horses. Cases have been reported, but clinical signs and subsequent prognostic indicators have been poorly documented and must be extrapolated from cases in companion animals. We describe in detail the poisoning of a horse that consumed a lethal dose of the carbamate, methiocarb.

Arthroscopic approach to the subextensorius recess of the lateral femorotibial joint of the foal.

Objective: To (1) develop an arthroscopic approach to the subextensorius recess of the lateral femorotibial (LFT) joint in foals and (2) report its use in foals with LFT joint sepsis.

Study Design: (1) Anatomic study and (2) retrospective case series.

Sample Population: (1) Cadaveric hind limbs (n = 32 foals) to delineate the anatomy of the subextensorius recess; 13 foal limbs for cadaver surgery to assess the approach to the subextensorius recess; and (2) foals (n = 8) with LFT joint sepsis.

Local anesthesia and hydro-distension to facilitate cystic calculus removal in horses.

Objective: To report a technique for improving surgical access to the bladder for removal of cystic calculi in male horses.

Study Design: Retrospective case series.

Animals Or Sample Population: Geldings (8) with cystic calculi.

Transection of the lateral and long digital extensor tendons in racehorses.

Objective: To report on the outcome of wounds to the hindlimb of racehorses, and horses with the intended use of racing, where both the long digital extensor (LoDE) and lateral digital extensor (LaDE) tendons had been completely transected.

Design: Retrospective case series.

Methods: Records of all horses admitted with hindlimb lacerations between 2002 and 2009 were examined for cases where both the LoDE and LaDE tendons in the hindlimb had been severed, and specifically in horses intended to be used for racing.

Distal luxation of the patella in a horse.

A 19-year-old Thoroughbred gelding presented with sudden onset, non-weight bearing lameness in the right hindlimb. Radiography confirmed distal luxation of the patella, which was replaced into its normal anatomical location under general anaesthesia. There were no pathological sequelae noted on follow-up examination 9 months after the initial injury.

Lag screw fixation of dorsal cortical stress fractures of the third metacarpal bone in 116 racehorses.

Reasons For Performing Study: The effectiveness and best method to manage dorsal cortical stress fractures is not clear. This study was performed to evaluate the success of lag screw fixation of such fractures in a population of Thoroughbred racehorses.

Hypothesis: Lag screw fixation of dorsal cortical stress fractures is an effective surgical procedure allowing racehorses to return to their preoperative level of performance.
