November/December Self TestApril 17, 2009 A 9-month-old boxer presented with an inability to chew on the left side of its mouth. Pre-anesthetic testing, including blood chemistry profile, CBC and U/A, were normal. Under general inhalation anesthesia, the patient’s heart rate and blood pressure accelerated with exploration of tooth #309’s incisal surface. There was no sign of pulp exposure but attrition was noted. Tooth #409 appeared normal upon intraoral exam and digital oral radiology showed no evident pathology. What is your diagnosis? What other tests should be run? Click here for the answer ANSWER: During the initial exam, the client mentioned that the boxer mainly chews on its left side. The owner had been giving pig ears and cow hoofs as treats. The cusp of tooth #309 was worn and the pulp was visible. Even though there was no pulp exposure that does not mean that the pulp in this tooth was healthy. Reparative dentin is formed in response to wear or trauma to dentin and reparative dentin does not always protect the pulp. It can be deposited in a pulp that is irreversibly inflamed and its presence does not …

Senate Amendment Alters Mandatory Spay/Neuter Bill In CaliforniaApril 17, 2009 California Assembly Bill 1634, which would have mandated neutering dogs and cats in the state, was significantly amended and no longer requires pet sterilization. Instead, the bill stiffens penalties for existing laws associated with unneutered dogs and cats. Specifically, the bill would increase the fines for owners of intact cats and dogs impounded by animal control agencies from $35 to $50 for the first occurrence. For dogs, that fine would increase from $50 to $100 for the second occurrence and require sterilizing the dog, at the owner’s expense, on the third occurrence. Cats would need to be sterilized following the second occurrence. The amended legislation also calls for a fine for intact animals when the owner is cited for another animal-related complaint, except for excessive noise or barking. The fines, which would be in addition to fines associated with the original complaint, would be $50 for first occurrence for cats or dogs. Just as with the impound fines, that fine for dogs would be $100 for the second occurrence and require neutering on the third occurrence. Owners would be required to sterilize cats following the second occurrence. The fines can …

Antioxidants' Effects On Cancer Therapy UnclearApril 17, 2009 In human oncology journals, debate is raging about whether cancer patients should receive antioxidants during radiation and chemotherapy treatment. The human literature is rife with articles like, "Use of antioxidants during chemotherapy and radiotherapy should be avoided"1 and "Multiple dietary antioxidants enhance the efficacy of standard and experimental cancer therapies and decrease their toxicity."2 In 2004, an entire issue of Integrative Cancer Therapies focused on the topic, chock full of well-defended reasons why one should and should not combine the two. In the end, Keith I. Block, MD, the journal's editor-in-chief, scientific director of the Institute for Integrative Cancer Research and Education and medical director of the Block Center for Integrative Cancer Care at the University of Illinois, added the following comment: "Even with these excellent articles and more than two decades of personal clinical work on antioxidants, I feel the question is still open."3 Typically, products designed to lessen side effects display strong antioxidant properties, whether they are dietary supplements, herbal mixtures or vitamin combinations. Animals receiving these products may indeed feel better during treatment and be able to endure cytotoxic therapy longer. But at what cost? No one knows for sure. Unanswered …
Speaking In Veterinarian To Lawyers Of The FutureApril 17, 2009I recently played schoolteacher at my local law school. Like most U.S. law schools, this one has been entreated to adopt animal law offerings in advance of the burgeoning number of animal law cases. With topics as diverse as death benefits for pets, common cruelty cases, puppy mill claims and veterinary malpractice scenarios, animal law is making significant inroads, at least in the classroom. Lawyers-to-be have pushed for animal law curricula at their schools, and students have packed the classrooms. Though not all have gone on to make a difference in animals’ lives through law, the population of lawyers waiting to tackle significant animal cases is undeniably growing. According to a February Associated Press story, “Incidents of [animal] abuse and a shifting national consciousness have made this one of the fastest-growing fields in the legal profession. In 1993, just seven states had felony animal cruelty laws; today, all but four do.” That’s why law schools are looking for veterinarians willing to lend a vet’s-eye view to those who would either see us squashed like a bug in a malpractice lawsuit, fight on our side against those who commit crimes against animals, or push for higher standards for treatment of animals …
California Governor Proposes Taxing Veterinary ServicesApril 17, 2009 California Gov. Arnold Schwarzenegger announced a plan Thursday that would raise the state's sales tax rate and apply it to veterinary services, among other services, to help fix the state’s $11.2 billion budget shortfall. “We have drastic problems that require drastic and immediate action—we must stop the bleeding right now,” Schwarzenegger said in a statement. The state's sales tax rate is 7.25 percent. Many counties add to that basic rate. Under the proposal, Los Angeles County's sales tax rate would be 10.25 percent. Hawaii, New Mexico and South Dakota are the only states that currently tax veterinary medical services, including routine exams and vaccinations, according to the American Veterinary Medical Assn.’s state tax summary report. While California does not tax ancillary veterinary services, such as grooming and boarding, or prescription medications, it does tax non-prescription products, as do 33 other states. Only eight states charge no taxes of any kind on animal products or services. “The regulations and exemptions on sales tax vary greatly from state to state,” said David Kirkpatrick, AVMA media relations manager. Members at the California Veterinary Medical Assn. are not thrilled with Schwarzenegger’s plan. “We strongly believe that …

Salmon Poisoning Disease Found In Southern CaliforniaApril 17, 2009 A recent case of salmon poisoning disease (SPD) in two dogs in Southern California is prompting veterinarians to warn pet owners about the potential risks involved in allowing dogs to be exposed to raw salmonid fish. The potentially fatal disease is usually found in the Pacific Northwest and can affect dogs, wolves, ferrets and foxes that ingest uncooked salmon, trout, steelhead and similar freshwater fish. Symptoms include vomiting, loss of appetite, fever, diarrhea, weakness, swollen lymph nodes and dehydration, signs that can often be confused with other gastrointestinal diseases. “Most people in this area [Orange County] are unfamiliar with the symptoms of this disease, which appear within five to seven days after eating infected raw fish,” says Mike Moore, DVM, Dipl. ACVIM, at VCA All-Care Animal Referral Center in Fountain Valley, who treated the patients. “Left undiagnosed, SPD can be fatal within several weeks. SPD is treatable if diagnosed quickly.” Dr. Moore, who had practiced in Washington for several years and was familiar with the disease, says he suspected SPD when the pet owners told him that their 10-month-old Yorkie and her 2-year-old mother had ingested raw fish from the Santa Ana River Lakes. …
Researchers Identify Virus Linked To PDDApril 17, 2009Researchers at the University of California, San Francisco, say they have identified the virus linked to proventricular dilatation disease, or PDD, a fatal nervous system disorder in domesticated and wild birds in the psittacine family. The researchers also developed a diagnostic test for the virus, avian bornavirus (ABV) . Other members of the bornavirus family encephalitis in horses and livestock. "This discovery has potentially solved a mystery that has been plaguing the avian veterinary community since the 1970s," said Joseph DeRisi, Ph.D., who led the team with Don Ganem, MD, both professors and Howard Hughes Medical Investigators at UCSF. "These results clearly reveal the existence of an avian reservoir of remarkably diverse bornaviruses that are dramatically different from anything seen in other animals." Drs. DeRisi and Ganem said that the discovery could have profound consequences on both domesticated parrots and in the conservation of endangered species. For instance, the Spix's Macaw is currently one of the most endangered birds in the world and is threatened by PDD, numbering at about 100 worldwide, according to the researchers. It had been theorized that a viral pathogen was the source of the disease, but until now, no one had been able to identify …
