This cross-sectional study by Marcha Badenhorst and coworkers in Austria, Germany and Switzerland investigated the prevalence, geographical distribution, genetic diversity, pathogenesis and risk factors of equine parvovirus-hepatitis (EqPV-H) in Austrian equids.Sera from 259 healthy horses and 13 healthy donkeys were analysed for the presence of EqPV-H antibodies and EqPV-H DNA (PCR). Associations between infection status, sex, age and concurrent equine hepacivirus (EqHV) infection were described. Glutamate dehydrogenase (GLDH), gammaglutamyl transferase (GGT), bile acids and albumin concentrations were compared between horses with active infection and PCR-negative horses. Phylogenetic analysis of the EqPV-H variants was performed.In horses, EqPV-H seroprevalence was 30% and DNA prevalence was 8.9%. One horse was co-infected with equine hepacivirus. No evidence of EqPV-H was detected in donkeys. Horses over 16 years of age were eight times more likely to have active EqPV-H infection compared with horses 1-8 years of age, and were three times as likely to have active EqPV-H infection compared with horses 9-15 years of age. GLDH, GGT, bile acids and albumin concentrations were not significantly different between horses with active infection and those without. The EqPV-H variants identified in this Austrian population of horses showed high similarity to sequences worldwide. No evidence of EqPV-H was detected in donkeys.EqPV-H antibodies and DNA are frequently detected in Austrian horses, without associated hepatitis. The risk of active EqPV-H infection increases with age. Effect of diet on equine peripheral cariesThis retrospective review by Kirsten Jackson and co-workers in Australia investigated the effect of replacing oaten hay with a non-cereal hay on equine peripheral caries in 42 cases.Recent research suggests that diets with high water soluble carbohydrate (WSC) content are associated with high risk of peripheral caries. This study investigated whether the peripheral caries process can be halted if oaten hay is removed from the diet and replaced with a non-cereal hay which is typically lower in WSC. Forty-two horses with peripheral caries were switched from oaten hay to a non-cereal hay or straw. Photographs taken at the time and again at subsequent visits were anonymised, randomised, and scored by six equine veterinary dentists using the Jackson et al. 'Peripheral Caries Grading System' grading scale.At follow-up, 69% of cases were marked as inactive, compared with 47.6% of cases at baseline. Significantly lower grades of peripheral caries were observed in the gingival, middle and occlusive third of the molars at follow-up compared with baseline. Significant improvements were not observed in the premolars.Recommending that clients change their horse's diet from oaten hay to a lower WSC hay may be useful as part of longterm management of equine peripheral caries.

“…MRI is fast becoming the gold standard diagnostic tool for musculoskeletal disorders of the distal limbs in equines, in a way that was not previously possible (MURRAY et al, 2006;MIZOBE et al, 2016;ELLIS et al, 2020;ELEMMAWY et al, 2020;ABU-SEIDA and ELEMMAWY, 2021). The use of MRI overcomes the potential disadvantages of both radiography for diagnosis of osseous lesions and ultrasonography for diagnosis of soft tissue injuries (ELEMMAWY et al, 2019).…”

Magnetic resonance imaging (MRI) is fast becoming the gold standard diagnostic tool for lameness in equines. This case report describes the MRI features of multiple phalangeal disorders in a 9-year-old horse with chronic unilateral forelimb lameness due to severe trauma. A complete case history was taken, and a thorough clinical examination, radiography, ultrasonography and MRI were performed. Radiography and ultrasonography showed limited value. MRI revealed edema of the navicular bursa (NB), distal sesamoidean impar desmitis, DDFT injury at navicular and post-navicular levels, cartilage erosion of the pastern and coffin joints, medial collateral desmitis of the fetlock joint, medial collateral sesamoidean desmitis, and lateral collateral desmitis of the coffin joint. In conclusion, severe trauma may induce multiple phalangeal disorders with severe pain in draft horses, and MRI is superior to other diagnostic imaging modalities, such as radiography and ultrasonography, for diagnosing such cases.
