An eight-month-old mixed-breed dog was presented with a history of sudden onset pelvic limb lameness. Radiographic and computed tomographic examinations demonstrated an osteolytic process involving the lumbar spine and pelvis. A comprehensive work-up including serial radiographic skeletal survey, biopsy, routine laboratory investigation and evaluation of parathyroid hormone (PTH) and 25-hydroxy-vitamin D levels failed to reveal any underlying cause for the osteolysis. Conservative treatment using the bisphosphonate drug alendronate and oral analgesic medications resulted in a return to nearly normal long-term function, despite massive lumbar and pelvic osteolysis. The clinical, radiological and histopathological features in this dog are reported, and similarities with the human condition known as Gorham's disease are discussed. © Schattauer 2011. Source

Case report: Metaphyseal osteopathy (MO) was diagnosed in three Australian Kelpie puppies that were presented for veterinary assessment of lameness. The three puppies were siblings. Each was from a different litter by the same breeding pair. The puppy in case one was seen by the authors, and the puppies in cases two and three were patients at other veterinary hospitals. However, the medical records and radiographs were examined and reviewed for this report. Radiographic investigation of the lameness revealed pathognomonic appearance of MO affecting the metaphyseal region of the long bones in all three puppies. The diagnosis was confirmed on histopathology in one patient. Conclusion: MO is considered a disease of large and giant-breed dogs, being rarely reported in non-large-breed dogs, and has not been reported in the Australian Kelpie, which is considered a medium-breed dog. This case series suggests a previously unreported breed predisposition to MO in the Australian Kelpie. © 2014 Australian Veterinary Association. Source

Objective: To report a staged approach that includes selective dental extractions before definitive double-layer hard palate defect closure in dogs. Study Design: Retrospective case series. Animals: Dogs (n=6) with a palatal defect. Methods: Dogs had selective maxillary teeth extractions 4-8 weeks before definitive hard palate defect repair by double-layer local full-thickness mucosal flaps. Results: All palatal defects were considered complex. Complete hard palate closure was achieved after initial attempt in 3 dogs; 2 dogs had revision surgery before complete closure, and in 1 dog, closure failed and further treatment was declined. No complications or long-term consequences were associated with selective dental extractions. Conclusions: Selective dental extractions before definitive surgical repair using mucosal flaps in a double-layer approach is an effective alternative when treating complex hard palate defects in dogs. © 2014 by The American College of Veterinary Surgeons.

Objective: To determine if differing gauge (G) needles used for venipuncture altered the automated platelet count and coagulation profile (prothrombin time (PT) and activated partial thromboplastin time (aPTT)) in clinically healthy dogs. Design: Prospective, observational, randomised, clinical study. Methods: We enrolled 20 clinically healthy dogs. Blood was collected via direct venipuncture of the jugular veins with 21G, 23G and 25G needles in a random order. Automated haematology and automated coagulation times were performed on the blood samples. Values were analysed for differences among the needle gauges and also the order of sample collection. Results: No difference was found in the automated platelet count or automated coagulation times for the three needle gauges used or the order in which the samples were collected. Conclusion: Venipuncture can be performed with a 21G, 23G or 25G needle to obtain blood from dogs for automated platelet count and PT/aPTT measurement without affecting the results. © 2014 Australian Veterinary Association.

Case report: A normolipaemic 7-year-old female spayed Domestic Shorthair was initially presented with a history of pruritus for several years and diagnosed with concurrent atopic dermatitis, flea bite hypersensitivity and adverse food reaction. The hypersensitivities were controlled with cyclosporin, allergen-specific immunotherapy, topical flea control and a restricted diet. Five months after initial presentation, the cat developed a non-healing nodular ulcerated cutaneous lesion in the left axilla and also developed immune-mediated haemolytic anaemic (IMHA). The IMHA was stabilised, but the axillary lesion persisted and progressed to a diffuse, firm, yellowed subcutaneous swelling over the ventral body approximately 20 months later. Histopathology was consistent with cutaneous xanthoma. The cat was normolipaemic and being fed a home-prepared diet of lean kangaroo meat and pumpkin to manage pruritus associated with adverse food reactions. No underlying malignancy was detected on routine screening tests. Conclusion: A diffuse, planar form of cutaneous xanthoma occurring without associated lipaemia has not been previously reported in cats. © 2013 Australian Veterinary Association. Source
