Victoria, British Columbia — The Supreme Court of British Columbia issued a broad injunction that prohibits non-veterinarians from performing any dental procedures or using a title, such as equine dentist, that might lead people to believe they are registered under the territory's Veterinarians Act.
Magnetic resonance imaging (MRI) results from the effect of magnetic properties of atoms found in biologic tissues. The magnetic moment of the nuclei within these atoms interacts with the external magnetic field, the most common of which is hydrogen. Hydrogen is abundant in all tissues and has a relatively large magnetic moment, making it the optimal choice for magnetic resonance imaging.
Louisville, Ky. — The Thoroughbred racing Mecca was amid heightened biosecurity following recent outbreaks of equine herpesvirus and a mysterious illness that claimed the life of Kentucky Derby contender With a City.
Blacksburg, Va. — John Robertson, VMD, MS, PhD, director of the University of Virginia-Maryland Center for Comparative Oncology, is experimenting with frankincense oil as a possible treatment for malignant melanoma in horses.
Though many experts believe magnetic resonance imaging (MRI) is underused in equine veterinary medicine, greater availability of the technology and access to interpretation experts are facilitating greater adoption, especially when diagnosing lameness.
Private equine practice is largely a matter of lameness, reproductive issues, trauma care and preventive medicine. There are occasions, however, when behavior problems directly affect medical care, and veterinarians must be able to address these issues to deliver appropriate treatment.
Neoplasia is generally an uncommon occurrence in horses. "As a species, horses appear to have less of a predisposition to cancer," says John Robertson, VMD, PhD, director of the Center for Comparative Oncology at The Virginia-Maryland Regional College of Veterinary Medicine. "The overall incidence of neoplasms in horses is lower than in other long-lived species, i.e., humans, cats and dogs."
Austin, Texas — A partnership between ViaGen Inc. and Encore Genetics produced the first commercially cloned mare in the United States. Royal Blue Boon Too is the genetic replica of a champion cutter owned by Elaine Hall.
Dysphagia in the neonatal foal manifests itself as the presence of milk in the foal's nares after nursing. Milk reflux in a foal should not be ignored. Aspiration pneumonia is the usual secondary consequence.
There are a variety of hormonal therapies available to the equine practitioner to help bring mares into estrus and hasten ovulation. They include human chorionic gonadotropin (hCG), various progestin/estradiol combinations, gonadotropin releasing hormone (GnRH) analogs, and dopamine antagonists. These hormonal therapies push Mother Nature along to help make the breeding process more efficient, reduce excessive handling of mares and stallions, and help ensure successful breeding and conception, whether a maiden, a previously barren or a cyclic mare.
Much of the focus and effort put forth on breeding farms this spring will center on mares and the various reproductive problems that they experience. Stallions are often given minimal attention other than bacterial cultures and examination of early season ejaculates unless there are unusually high numbers of return "open" mares or evidence of serious problems.
