Spinal MR images acquired from canine patients over a 7-year period were reviewed for the presence of vertebral endplate changes. Seventy-five dogs with 76 distinct lesions were identified. Presumptive diagnoses fell into five categories: reactive endplate changes (10 dogs/13.2%), discospondylitis (29 dogs/38.2%), vertebral osteochondrosis (7 dogs/9.2%), intravertebral disc herniation (Schmorl's nodes) (4 dogs/5.3%), and fatty infiltration (26 dogs/34.2%). Fatty infiltration occurred significantly more often in small breed dogs (P < 0.001) and tended to be multifocal. The following features were observed in discospondylitis as well as in other nonfatty endplate pathologies: irregular endplates, endplate hyperintensity in T2w or STIR images, reduced endplate signal intensity in T1w SE, variable T1w GRE signal intensity, and endplate contrast enhancement. Overlap between MR characteristics of nonfatty endplate changes should prompt cautious evaluation of adjacent structures.

“…Similar to the human experience, 20 reactive endplate changes in our population had a predilection for the lumbosacral joint (5/10: 50%), an association with degenerative disc changes (9/10: 90% with grade 4) and a tendency to affect older patients (6/10: 60% over 7 years of age).…”

“…Additionally, in GSDs, there is an increased prevalence of congenital anomalies that can predispose affected dogs to DLSS. A separated osteochondral lesion of the dorsal endplate of S1 (or more rarely L7) that histologically resembles osteochondrosis has been reported in the GSD 30–32. Ondreka et al (2013) reported a 10% incidence of sacral osteochondrosis in GSDs compared to ~6% in non-GSDs and found a moderate heritability of 0.5 in GSDs 33.…”

Canine degenerative lumbosacral stenosis (DLSS) is a syndrome of low back pain with or without neurologic dysfunction associated with compression of the cauda equina. Most commonly occurring in medium- to large-breed dogs of middle to older age, German shepherd and working dogs are predisposed. Diagnosis is based on a combination of clinical signs, advanced imaging and ruling out other differential diagnoses. The volume of the intervertebral foramina at the lumbosacral junction is naturally reduced on extension but degenerative changes lead to a more marked reduction that can impinge the L7 nerve roots. Evidence is lacking on which to base decision-making for treatment of dogs with DLSS. However, surgical intervention may be indicated in dogs that do not respond to conservative management, or for dogs in which there is a requirement to work that prevents lifestyle adjustments. Improvements in electrodiagnosis and novel intra-discal treatments may improve the management of DLSS in the future.

Bandaging the limbs with a non-occlusive dressing in a 3-layer bandage has no effect on total time to healing of distal wounds in horses, as long as the excessive granulation tissue is excised regularly, this study finds. 1The authors used data from 33 adult horses from four studies of the same wound-healing model over a 5-year period. Wounds were made in the skin over the dorsomedial aspect of the mid-metacarpus, and 17 were bandaged and 16 were not.The wound areas, which were analysed by weekly photography and image analysis, were not different between groups initially but were different at all subsequent times. Unbandaged wounds retracted for 2 weeks before beginning to contract; bandaged wounds continued to retract for 3 weeks. Excess granulation tissue required regular trimming in bandaged but not in unbandaged wounds. Total days to healing and overall rate of healing were similar in each group. The authors conclude that although their results should be treated with caution until validated with controlled studies undertaken at the same time, bandaging lead to greater wound retraction, modulated the rate of wound contraction and promoted excessive granulation tissue. Auricular chondrosis in a horseThis case report of auricular chondrosis in a horse shows different histological features from those recorded previously for this condition in cats, dogs, laboratory animals and humans. 2A 4-year-old crossbred, Welsh Mountain Pony gelding was presented with multiple, thick, round, raised, 3 to 8 mm diameter nodular lesions that had developed over several months on the medial aspects of both ears. These did not involve the epidermis. There was no evidence of pain, pruritis or erythema. Histopathological examination of punch biopsies showed auricular chondrosis, with central areas of degeneration and lysis, deposition of cartilage along the margins, and no evidence of inflammation. The nodules have persisted in spite of treatment with oral prednisolone. National survey of antimicrobials in the Australian pig industryResults of a national survey suggest that Australian pig farmers place a widespread reliance on antimicrobials, but that drugs used are of low importance to human public health. Most of the 197 herds that responded relied on drugs that are of low importance in respect of the effect resistance would have on human health (e.g. tetracyclines, penicillins and sulfonamides). Ceftiofur and virginiamycin, the drugs of high importance in human medicine that can be legally prescribed to pigs, were reported in 25% and 0% of herds respectively. Most use of antimicrobials was for infections attributed to Lawsonia , Mycoplasma and Escherichia coli .The authors recommend reducing risk of antimicrobial resistance relevant to public health by improving control of E. coli infections without relying on antimicrobials. They noted the wide variation in usage between herds, and suggest that herd antimicrobial use should be constantly reviewed.
