Cadaver evaluation and retrospective case series. One canine cadaver; 3 client-owned dogs. Craniotomies of different sizes and at different locations were performed with MBS. Dural tear and bone discoloration were recorded. Clinical, imaging, and surgical findings of dogs diagnosed with MLO and where MBS was used for craniectomies were retrospectively included. Cadaveric evaluation identified MBS as an efficient tool for rapid craniectomies (>5minutes) albeit dural tears and some small foci of bone discoloration were observed. Craniectomies could be performed without complications in 3 dogs with MLO without dural tear or bone discoloration. .Excision was in complete in all cases. The short-term outcome was good, and the long-term outcome was fair to good. Piezoelectric bone surgery with the Misonix bone scalpel is an alternative technology to perform craniectomies in dogs. It was not associated with complications in 3 dogs diagnosed and surgically treated for MLO. Dural tears and suspected bone necrosis can occur. Great care should be taken when using CT to establish disease free surgical osteotomy.}, journal={TOPICS IN COMPANION ANIMAL MEDICINE}, author={Piazza, Alexander M. and McAnulty, Jonathan F. and Early, Peter and Guevar, Julien}, year={2023} }

The puppy underwent a physical and neurological examination, serum biochemistry and complete blood cell count, electrophysiological testing, muscle biopsy and whole genome sequencing. Clinical evaluation revealed generalized neuromuscular weakness with tetraparesis and difficulty holding the head up and a dropped jaw. There was diffuse spontaneous activity on electromyography, most severe in the cervical musculature. Nerve conduction studies were normal, the findings were interpreted as consistent with a myopathy. Skeletal muscle was grossly abnormal on biopsy and there were necklace fibers and abnormal triad structure localization on histopathology, consistent with myotubular myopathy. Whole genome sequencing revealed a premature stop codon in exon 13 of MTM1 (ChrX: 118,903,496 C > T, c.1467C>T, p.Arg512X). The puppy was humanely euthanized at 5 months of age. The puppy's dam was heterozygous for the variant, and 3 male puppies from a subsequent litter all of which died by 2 weeks of age were hemizygous for the variant. This naturally occurring mutation in Boykin spaniels causes a severe form of X-linked myotubular myopathy, comparable to the human counterpart.}, number={5}, journal={Neuromuscular Disorders}, publisher={Elsevier BV}, author={Olby, Natasha J. and Friedenberg, Steven and Meurs, Kathryn and DeProspero, Dylan and Guevar, Julien and Lau, Jeanie and Yost, Oriana and Guo, Ling T. and Shelton, G.

Traditional techniques have been used for many years, but there has now been a progression to move towards alternative digital models and interactive 3D models to engage the learner. However, digital innovations in the curriculum have typically involved the medical curriculum rather than the veterinary curriculum. Therefore, we aimed to create a simple workflow methodology to highlight the simplicity there is in creating a mobile augmented reality application of basic canine head anatomy. Using canine CT and MRI scans and widely available software programs, we demonstrate how to create an interactive model of head anatomy. This was applied to augmented reality for a popular Android mobile device to demonstrate the user-friendly interface. Here we present the processes, challenges and resolutions for the creation of a highly accurate, data based anatomical model that could potentially be used in the veterinary curriculum. This proof of concept study provides an excellent framework for the creation of augmented reality training products for veterinary education. The lack of similar resources within this field provides the ideal platform to extend this into other areas of veterinary education and beyond.}, number={4}, journal={PLOS ONE}, author={Christ, Roxie and Guevar, Julien and Poyade, Matthieu and Rea, Paul M.}, year={2018}, month={Apr} }

Dogs with sensorimotor complete injuries have an incomplete recovery. Pulsed electromagnetic fields (PEMFs) reduce post-operative pain through anti-inflammatory effects and there is growing evidence for neuroprotective effects. This randomized, controlled clinical trial evaluated the effect of PEMF on post-operative pain and neurological recovery in dogs with surgically treated sensorimotor complete SCI attributed to acute IVDE. Sixteen dogs with surgically treated complete thoracolumbar SCI were randomized to receive PEMF (15 min every 2 h for 2 weeks then twice-daily for 4 weeks) or placebo starting immediately after diagnosis. The primary outcome was gait score at 2 weeks. Secondary measures of gait, pain perception, and proprioceptive function were evaluated at 2 and 6 weeks. Plasma glial fibrillary acidic protein (GFAP) concentration was measured as an SCI biomarker. Post-operative pain was quantified by measuring mechanical sensory thresholds (MSTs) at control and surgical sites. There was no significant difference in demographics or GFAP concentration between the two groups at trial entry. There was no difference in primary outcome or in secondary measures of gait, but proprioceptive placing was significantly better at 6 weeks and GFAP concentrations were significantly lower at 2 weeks in the PEMF group. MSTs were significantly higher in the PEMF-treated group. We conclude that PEMF reduced incision-associated pain in dogs post-surgery for IVDE and may reduce extent of SCI and enhance proprioceptive placing. Larger clinical trials are warranted.}, number={15}, journal={Journal of Neurotrauma}, publisher={Mary Ann Liebert Inc}, author={Zidan, Natalia and Fenn, Joe and Griffith, Emily and Early, Peter J. and Mariani, Chris L. and Muñana, Karen R. and Guevar, Julien and Olby, Natasha J.}, year={2018}, month={Aug}, pages={1726–1736} }

Forty‐seven different neurological presenting signs were reported with 79 per cent of the donated patients presenting with abnormal gait. All cases presenting with abnormalities in more than 4 out of 10 neurological categories died or were euthanased on welfare grounds. Calves were significantly more likely to present with neurological disorders than adult cattle compared with the proportion of calves: cows in the Scottish cattle population and total case population donated to SCPAHFS. Lesions were most commonly localised to the spinal cord in sheep 47 per cent (16), the peripheral nervous system in cattle 45 per cent (28) and to the brain in the overall population 41 per cent (39). The most common aetiology of neurological pathologies observed was infectious or inflammatory 28 per cent (27). Definitive diagnoses could be reached in 84 per cent (81) of patients. When postmortem reports were available, they produced a diagnosis in 70 per cent (52) of cases and contradicted clinical diagnoses in 38 per cent (26) of cases.
