How To Treat Osteosarcoma When Surgery Is RefusedApril 17, 2009 Osteosarcoma (OSA) is a common and devastating cancer that plagues many of our canine patients. Standard-of-care therapy continues to include the recommendation for surgical removal of the primary tumor through amputation or through limb-sparing surgery followed by chemotherapy. However, some patients may not be good candidates for amputation or their owners may prefer to pursue non-surgical alternatives. Recent years have brought new radiotherapy techniques as well as new options for pain control. External beam radiation therapy has been studied as a palliative treatment for OSA for many years and is used strictly to impart local pain control. Total radiation doses of 24 to 36 Gy are administered to the tumor site over three to four weekly fractions. Significant pain relief is expected in 74 to 92 percent of dogs for a median of two to three months, although most dogs will still require some pain medications. Skin reactions are mild with this palliative dosing scheme and generally do not affect quality of life. Local tumor control is not expected with this treatment modality and, occasionally, pathologic fracture may occur at the tumor site. This treatment option is available at many universities and specialty practices across the …

Canine Distemper Outbreak In Los AngelesApril 17, 2009 Los Angeles Animal Services reported a canine distemper outbreak in the city, and officials are urging pet owners to get their dogs vaccinated, according to the Los Angeles Daily News. The outbreak was declared after approximately six dogs with the disease were brought into city shelters, reported the paper. The shelters typically see one dog with the disease every two weeks. Canine distemper is a highly contagious airborne virus that attacks the respiratory, gastrointestinal and nervous system of dogs and puppies, according to the American Veterinary Medical Association (AVMA). Symptoms include fever, eye inflammation and discharge, nasal discharge, reduced appetite, vomiting, diarrhea and lack of energy. According to the AVMA, the best protection against the disease is vaccination. The disease itself is treatable, but not curable according to the AVMA. <HOME>
Titers Join Debate On Vaccine FrequencyApril 17, 2009 For clients, vaccines are part of routine pet care and for the most part, veterinarians can expect owners to comply with vaccine reminders and schedule an appointment. While the visit serves as an opportunity to examine the pet for other maladies, one thing is certain: The pet will be vaccinated before it leaves. Some veterinarians maintain that administering core vaccines every three years or even annually is outdated and isn’t practicing good medicine. While practitioners argue that liability or a patient contracting a virus outweighs the risk of a potential vaccine reaction, critics interject the titer argument. “Few veterinarians are proactive about discussing the options clients have in protecting their pets against disease,” says W. Jean Dodds, DVM, founder of Hemopet, a non-profit veterinary blood bank in Garden Grove, Calif. “The industry promotes more vaccines and veterinarians feel comfortable telling clients they’re necessary. Often, technicians have vaccines prepared before the doctor even examines the animal. Many vets don’t know how to handle titers or don’t want to bother with them.” Vaccine experts liken the three-year protocol to that of children’s vaccine regimens, which have come under public scrutiny after accusations that they cause autism. Although …
Senior Wellness Programs Bolster CareApril 17, 2009 You've probably had a scenario similar to this in your practice: A senior cat is presented for routine examination for the first time in 2 1/2 years. The owners report he has trouble eating, excess salivation, and sure enough, a monster tumor is identified, well seated in and under the tongue. Though these can carry a poor prognosis at any stage, we can't help thinking that it might have been salvageable if picked up at a very early stage. Other times the story has a happy ending for seniors, such as when a routine visit identifies a renal condition that stabilizes with therapy. The human population is undergoing a tremendous shift as baby boomers age; average lifespan tops 78 years. Our pet population has benefited from modern veterinary care and changes in lifestyle and nutrition, and is now also living a much longer average lifespan. Clients expect high quality care for their senior pet once they understand opportunities for preventive intervention, and because of the progressively greater proportion of our patients (~25%) in the senior life phase, it behooves us to develop a sensible senior wellness program. Many practices do not currently offer a …
How To Treat The Rare And Deadly Nasal Cancer In Dogs And CatsNovember 1, 2004Nasal passage cancer generally develops very insidiously in older pets. It is rare in cats and not common in dogs. It composes about 1 percent of feline tumors and up to 2.5 percent of canine tumors. Long-nosed breeds (dolichocephalic) and senior dogs are at higher risk. Clinical Signs Of Nasal Passage The early signs of nasal cancer in dogs or cats are: Unilateral nasal and/or ocular discharge Epistaxis Stridor Loss of smell Loose teeth Sometimes pawing at the face Late-stage signs may include a facial deformity along the dorsal aspect of the maxillary bones or over the paranasal and frontal sinuses. Some cases develop a raised or pitting facial bone deformity. Some cases may exhibit a firm or soft focal, raised mass protruding around or between the eyes. Some cases may have a palatine deformity from the softening and bowing out of the hard palate due to demineralization of the palatine bone and growth of the mass. In every case of facial deformity, there is bone lysis and tumor invasion at that site. If the lesions extend into the brain, seizures and behavior changes are often exhibited. A complication of nasal cancer is the over production of mucus. It …
