Labradors affected with EIC—about 3 percent to 5 percent of Labs are said to have this condition—may start to lose control of their hind limbs after intense hunting or retrieving exercises. In most cases, their legs get wobbly and the limbs give out. In rare cases, they may die, according to researchers. …

Hahn, DVM, Ph.D. At least once daily, I'm asked by a pet owner, "My dog has had this lump on its side for some time now. What do you think it might be?" Rather than venture a guess and pick randomly from the 50-plus possible types of tumors that arise from the skin or adnexal structures, I pull out my syringe, needle, glass slides and Diff-Quik stains.Within 10 minutes I can answer the owner's question and, if necessary, recommend and perform appropriate diagnostic or therapeutic measures. Cytology PaysThe cytological examination of cells from effusion or masses is a useful (and profitable) diagnostic procedure. Samples for cytological evaluation can be easily collected from many epithelial structures, body cavities and internal organs. While cytological interpretation of fine-needle aspirates may …

The Balancing Act: Response And ToxicityApril 17, 2009oncologyoutlookThe Balancing Act: Response and ToxicityThe Balancing Act: Response and ToxicityThe Balancing Act: Response and ToxicityBy Kevin A. Hahn, DVM, Ph.D.I was asked the other day why no chemotherapy drugs are currently approved for use in veterinary medicine.I was asked the other day why no chemotherapy drugs are currently approved for use in veterinary medicine. I was asked the other day why no chemotherapy drugs are currently approved for use in veterinary medicine. It seems inconceivable that chemotherapy drugs such as vincristine, cyclophosphamide and doxorubicin could reach widespread application in veterinary medicine over the past 20 years without a thorough understanding of the pharmacology in various animal species. Why do we use the dosages that we use? Would the dosage be the same in a Chihuahua and a bull mastiff, different in a ferret or a fish? If you have had cancer or know someone with cancer, you have seen how clinical pharmacokinetics has been successfully applied to improve the safety and efficacy of chemotherapy administration. One Size Does Not Fit AllBut unlike many other classes of drugs (antibiotics, anti-arrhythmics), the anti-cancer agents vary greatly in their physical composition, reactivity, stability, subcellular sites of action …

Like gold, it is an elegant discipline left to the visual acuity and interpretation of the pathologist. Why does histopathology continue to be considered the gold standard for a diagnosis? While pathology's roots are closely associated with the history and progress of medicine, in particular the detection, understanding and classification of diseases, why is it still considered the gold standard despite technological advances in our understanding of the subcellular and genetic levels of the body? What is a "gold standard"? The term comes from the monetary system of many modern countries. Gold is considered the true value of a country's currency. If a country will redeem any of its money in gold, it is said to be using the gold standard. Why Gold?Gold is one of the oldest, most scarce known metals. It is considered an elegant and metal.

AMC's Renal Medicine Service has reviewed all chemistry profiles obtained at AMC between March 17-20. Owners of pets with azotemia have been contacted to determine if the pets had eaten the recalled foods. During this time period, 143 chemistry profiles were performed. Five percent of pets have been determined to have food-related acute renal failure. Twelve cases have been identified, 8 cats and 4 dogs. Age range was 2-14 years with a mean age of 7.4 years. All pets had at least one clinical sign of acute renal failure: 75 percent had anorexia, 50 percent had polyuria and polydipsia, 50 percent had vomiting and 50 percent had lethargy. …
Radiation Therapy In Cancer ManagementApril 17, 2009oncologyoutlook By Alice Villalobos, DVM For Veterinary Practice News Radiation therapy is used to manage 50 percent of human cancers. Approximately 7,500 radiation therapy machines are in use worldwide. Thin skin and hair loss are effects of radia-tion therapy for mast cell cancer.Courtesy of Dr. Villalobos The industry's technology went from orthovoltage in the 1950s to cobalt in the 60s and now to linear accelerators, or linacs. Four hundred older units will be replaced this year and an additional 300 new units will be installed. The cost of a new linac is $2.3 million. The new Hi-Art TomoTherapy unit was developed by researchers in Wisconsin and is considered the biggest innovation in RTx since the 1950s. It combines a linac and a CT scanner. Its price tag is $3.2 million. In the past, a lack of facilities limited radiation therapy as an option for pets. The need for heavy sedation or anesthesia for each treatment was another deterrent. Cost and logistics are additional factors for the pet owner to deal with. Short- and Long-term Risks of Radiation Therapy Radioation therapy Field (Tumor Bed) Short-term side effects Long-term …
