Author Abstract

The dentigerous cyst or temporal teratoma in horses is a well-known congenital malformation that occurs in the temporal region and usually contains dental tissue. This case report describes two horses with a previously unreported variant of the dentigerous cyst associated with an exostosis arising from the temporal bone. The principal clinical sign was a draining tract opening at the margin of the right pinna in both horses. There was no evidence of an ectopic tooth on the radiographs or at ultrasonographic examination. Computed tomography combined with positive contrast sinography of the draining tract revealed bone formation arising from the supramastoid crest of the right temporal bone extending towards a cyst-like structure but without direct connection in both cases. This bone formation was located at a site on the supramastoid crest, close to the external acoustic meatus, where ectopic teeth may also occur. Both cysts were removed surgically with a good long-term outcome.

"Do Your Homework as Your Heart Takes over When You Go Looking": Factors Associated with Pre-Acquisition Information-Seeking among Prospective UK Dog Owners.
Of potential owners, 68% reported already having looked for information, while a further 14% were planning to undertake research prior to acquiring a dog. Those with previous dog ownership experience were less likely to undertake pre-acquisition research, as were those who had worked with dogs. Among current owners, pre-acquisition research was more likely among those who acquired their dog through a breeder; a specific breed or a mix of two breeds; or as a puppy.
Clinical and epidemiologic features of persons accessing emergency departments for dog and cat bite injuries in California (2005-2019).
The average annual incidence of dog bites was highest in children aged < 10 years and males, while that of cat bites was highest in adults aged ≥ 80 years and females. Both dog and cat bite injuries were more likely to occur to upper limbs. Bacteria were isolated from 3% of dog bite injuries and 21.5% of cat bite injuries at initial presentation.
Feline Stress Management During air Travel: A Multimodal Approach.
While the discussion is focused on air travel specifically, the stress management methods described can be applied to all types of longer distance travel, such as a long road trip or a ferry crossing, as well as a stay in a holiday home.
Epidemiology and clinical presentation of feline presumed hereditary or breed-related ocular diseases in France: retrospective study of 129 cats.
In a French population of cats, presumed hereditary or breed-related ocular diseases accounted for 11.1% of all ocular diseases. Cataracts, corneal sequestration, persistent pupillary membrane, entropion, and retinal dysplasia were the most common conditions. Statistical breed over-representation was observed for entropion, corneal sequestration, and retinal dysplasia.
Antimicrobial use in the surgical treatment of canine pyometra: A questionnaire survey of Arizona-licensed veterinarians.
Overall, 76% of veterinarians stated they always use preoperative and perioperative antibiotics, and 74% stated they always use postoperative antibiotics. A total of 16 different antibiotics were reported. Twelve percent of respondents regularly submitted a culture. Culture submission was impacted by cost, prior experience, poor owner compliance, result turnaround time, and anticipated results.
