Putative contact ketoconazole shampoo-triggered pemphigus foliaceus in a dog
Hyun-Jeong Sung, In-Hwa Yoon, Jung-Hyun Kim (page 914)
A 10-year-old spayed female cocker spaniel dog was referred for an evaluation of acute-onset generalized pustular cutaneous lesions following application of ketoconazole shampoo. Cytologic and histopathologic examinations of the lesions revealed intra-epidermal pustules with predominantly neutrophils and acantholytic cells. This is the first description of putative contact ketoconazole shampoo-triggered pemphigus foliaceus in a dog.
Retinal astrocytoma in a dog
Keiichi Kuroki, Nathan Kice, Juri Ota-Kuroki (page 919)
A miniature schnauzer dog presenting with hyphema and glaucoma of the right eye had a retinal neoplasm. Neoplastic cells stained positively for glial fibrillary acidic protein, vimentin, and S-100 and largely negatively for oligodendrocyte transcription factor 2 by immunohistochemistry. The clinical and histopathological features of canine retinal astrocytomas are discussed.
Atlanto-axial malformation in an adult Quarter horse gelding
Robert Cole, Jennifer Taintor, Reid Hanson (page 923)
An adult gelding was evaluated for bilateral intermittent forelimb lameness of approximately 2 years duration. The horse was found to have grade 2/5 upper motor neuron-general proprioception ataxia with no cranial nerve deficits. During radiographic and gross necropsy examinations a novel atlanto-axial malformation of possible congenital etiology was found.

Guillaume B. Manneveau, Mickaël P. Robert, Caroline Tessier, Céline Bizon-Mercier (page 926)
This report describes a rare case of gastric impaction caused by a trichophytobezoar in a foal. This case highlights the difficulty in diagnosing this condition and reports surgical removal via a gastrotomy after failure of medical treatment.
Intramuscular mast cell tumors in 7 dogs
William P. Robinson, James Elliott, Stephen J. Baines, Laura Owen, Chris J. Shales (page 931)
Mast cell tumors (MCTs) are commonly encountered in dogs and have been reported in cutaneous, conjunctival, oral mucosal, and gastrointestinal locations, but not in an intramuscular location. Medical records at 2 referral centers in the UK were examined to find cases of MCTs in this location. Seven dogs were identified as having an intramuscular MCT by a combination of fine-needle aspirate cytology and computed tomography or ultrasound. None of the dogs had evidence of local lymph node metastasis. Six dogs had no evidence of distant metastasis and surgery was carried out as the primary treatment option. Three of those dogs also had adjunctive chemotherapy due to a high Ki67 value or high mitotic index. All 6 dogs that had had surgery were alive at follow-up with a minimum elapsed time of 7 months. One dog had a course of chemotherapy due to the location, size, and evidence of biological activity of the tumor and died 23 days afterwards. The prognosis of intramuscular mast cell tumors appears to be favorable in most cases.
Post-operative Salmonella surgical site infection in a dog
Marc Kent, Lindsay Boozer, Eric N. Glass, Susan Sanchez, Simon R. Platt, Lisa M. Freeman (page 936)
Following decompressive surgery for degenerative lumbosacral stenosis, a 6-year-old German shepherd dog developed a subcutaneous infection at the surgical site and discospondylitis at the lumbosacral intervertebral disc. Salmonella enterica subsp. enterica, serotype Dublin was recovered from the surgical site. Salmonella of a different serovar was isolated from a sample of the raw meat-based diet that the owner fed the dog.
Single incision laparoscopic-assisted ovariohysterectomy for an ovarian tumor in a dog
Daniel Lopez, Ameet Singh, Tanya F. Wright, Cathy Gartley, Meagan Walker (page 975)
This report describes a single-incision, laparoscopic-assisted ovariohysterectomy in a 6-year-old, intact female Keeshond dog for the staging and treatment of a left-sided ovarian tumor. Abdominal access was obtained using a modified-Hasson technique allowing for placement of a multi-channel, single incision laparoscopic surgery port. Following carbon dioxide insufflation, superficial laparoscopic exploration of the abdominal cavity was performed and then both ovarian pedicles were sealed and divided using a vessel-sealing device. Laparoscopic-assisted ovariohysterectomy was performed with the aid of a wound retractor for exteriorization of the mass. There were no perioperative complications and the patient was discharged 1 day after surgery. Histopathology of the mass revealed an ovarian teratoma. Telephone follow-up 608 days after surgery revealed a good clinical outcome. Single-incision, laparoscopic-assisted ovariohysterectomy is technically feasible for the treatment of selected ovarian tumors in the dog.
Effect of acupuncture on pain and quality of life in canine neurological and musculoskeletal diseases
Nuno E.O.F. Silva, Stelio P.L. Luna, Jean G.F. Joaquim, Heloisa D. Coutinho, Fábio S. Possebon (page 941)
This prospective study investigated the effects of acupuncture alone or combined with analgesics in chronic pain and quality of life assessed by owners for up to 24 weeks in 181 dogs with neurological and musculoskeletal diseases. The scores before and after the onset of treatment were evaluated using the Wilcoxon test and the evolution of success was evaluated by Kaplan-Meier curves. Differences were considered significant at P < 0.05. The success rates for Helsinki chronic pain index (HCPI), quality of life assessment, and visual analog scales (VAS) for pain and locomotion were 79%, 84%, 78%, and 78% of the animals, respectively, when both diseases and groups of treatment were combined. Dogs with musculoskeletal disorders had greater improvement in HCPI (P = 0.003) and VAS locomotion (P = 0.045) than those with neurological disorders. Use of acupuncture alone or in combination with analgesics reduced pain and improved quality of life in dogs with neurological and musculoskeletal diseases.
Convenience euthanasia in companion animals: Dilemma among veterinarians in Quebec
Dominick Rathwell-Deault, Béatrice Godard, Diane Frank, André Ravel, Béatrice Doizé (page 953)
Many veterinarians working in the field of companion animal medicine have to deal with requests for convenience euthanasia in their practices. As it is the case in other medical fields, veterinarians are trained to treat their patients. It is thus easy to understand that veterinarians consider convenience euthanasia as one of the most difficult ethical dilemmas they have to deal with in their practice. Regulatory boundaries concerning the practice of euthanasia are limited to the method use to induce the death of the animal but do not give any indication as to what should be the proper circumstances surrounding the request. To date, there are few articles on this matter and the perspective of veterinarians on the subject was rarely addressed. This article reports results obtained following a study conducted upon Québec's veterinarians on the topic of convenience euthanasia. The data was obtained via an online survey created by the research team to evaluate the perspective of veterinarians on the topic, how they perceived consequences of convenience euthanasia and what were the solutions they would take into consideration in order to help the profession on resolving their dilemma. The data collected sheds light on the existing duality between double allegiance regarding the duties emerging from the relation with the patient (animal) and the client (pet owner) veterinarian are facing in their daily practice. On one hand veterinarians recognized that 'convenience euthanasia' is contrary to animal welfare. On the other hand they also recognized the pet owner's right to ask for 'convenience euthanasia' when he can no longer care for its pet.
Comparison of methicillin-resistant Staphylococcus pseudintermedius adherence to 2 canine limb salvage endoprosthesis implants
Alim Nazarali, Ameet Singh, Shauna Morrison, Thomas W.G. Gibson, Joyce Rousseau, J. Scott Weese, Sarah E. Boston (page 964)
The objective of our study was to compare adhesion of methicillin-resistant Staphylococcus pseudintermedius (MRSP) to stainless steel (SS) and to tantalum (TA) canine limb salvage endoprosthesis implants in an in vitro experimental study. The median of the mean log10 colony forming units/mL for adherent MRSP was 4.96 (range: 4.63 to 6.33) for the TA endoprosthesis and 4.31 (range: 3.86 to 5.05) for the SS endoprosthesis (P = 0.009). Although the trabecular and porous design of the TA endoprosthesis provides mechanical benefits over the SS endoprosthesis, it may increase the risk of developing infection due to higher levels of bacterial adherence.
Prevalence of obesity in the equine population of Saskatoon and surrounding area
Hayley R. Kosolofski, Sheryl P. Gow, Katherine A. Robinson (page 967)
A retrospective study determined the prevalence of obesity and over-conditioning in horses in Saskatoon, Saskatchewan. Body condition score (BSC) was assessed for 290 horses from the Field Service practice at the Western College of Veterinary Medicine. The median BSC of horses was 6; however, 59 (20.3%) horses were classified as over-conditioned, and 24 (8.3%) as obese.
Intrahepatic cholelithiasis in dogs and cats: A case series
Hideyuki Kanemoto, Kenjiro Fukushima, Hajime Tsujimoto, Koichi Ohno (page 971)
A retrospective study of intrahepatic cholelithiasis (IC) in 9 dogs and 2 cats was conducted. Only 1 dog showed clinical signs related to hepatobiliary disease before referral and during the follow-up period. Intrahepatic cholelithiasis might be a subclinical finding in both dogs and cats.
