Treating Marijuana Toxicity

July 13, 2011

When veterinarians think of regionally specific illness, toxicity caused by consumption of native plants and exposure to infectious organisms typically comes to mind. In preparation for a move to Southern California, I studied the effects of sago palm ingestion and inhalation of Coccidioidomycosis with the anticipation of the conditions I would be diagnosing and treating in my clinical practice. I did not anticipate that I would end up treating such a large number of dogs presenting with clinical signs consistent with marijuana (cannabis sativa) consumption. As the sale of medical marijuana is legal in many California cities, dispensaries provide human patients with smokable or edible products. Unfortunately, humans can carelessly leave these products in locations accessible to their curious pets, leading to ingestion. Clinical Signs Although a pet could show signs of marijuana toxicity post-inhalation, the majority of cases I see are due to suspected or known oral ingestion. I have treated dogs almost exclusively, yet cats can be similarly affected. A 2002 study of 250 cases of marijuana exposure showed dogs to be the primary cannabis consumption culprits (96 percent). Cats followed in a distant second place (3 percent), and other species made …

The Health Benefits Of Therapeutic Fasting

July 11, 2011

Fasting and the calorie restricted diet have both shown benefits for human and animal health as well as a lengthening of lifespan.1 Fasting consists of stopping food, but there are a number of variations that allow the consumption of juice, supplements or other items. Calorie-restricted diets usually aim to reduce the caloric intake to 70 percent of what is considered “normal,” either on a daily basis or by alternate day extreme restriction. For humans, multiple nutrient-dense foods are consumed, with an emphasis on fruits and vegetables. For animals, calorie restriction research usually involves restricting the diet to 70 percent of whatever the control animals are eating. Even without an increase in nutrient density, these animal studies show improved health, less degenerative disease and increased lifespan. Calorie restriction induces a cellular response that results in decreased free radical production, increased resistance to free radical effects and production of other protective proteins.2 Oxidative stress resulting in clinical3 or subclinical chronic inflammation is considered to be the primary cause of aging and age-related degenerative disease.4,5 Ironically, as the benefits of fasting and a calorie-restricted diet gain increasing research support, both the human and the …

Endoscopy: Not Just For Specialists

May 23, 2011

Endoscopy, commonly used for biopsies, gastropexies and laparoscopic ovariohysterectomies, is becoming more popular with veterinarians for more complex procedures. As the use of non-invasive methods increases, many veterinarians are learning to use endoscopic equipment. While a veterinarian investing in endoscopy equipment might not perform all possible procedures, he or she can offer many cutting-edge treatments. “There are many benefits to performing endoscopic surgery,” says Athens, Ga., surgical consultant Clarence Rawlings, DVM, MS, Ph.D., Dipl. ACVS. “The patient experiences less stress, less pain and can return to normal performance levels faster. Clients often have an aversion to major surgery but are often more comfortable with a less invasive procedure. As veterinarians, we feel like we’re doing a better job when using it for the right procedures.” Dr. Rawlings says new equipment is always exciting to use, but he warns against using endoscopic equipment for the wrong reasons. Other options may be available, he says, and sometimes a case may need to be referred. “I’m always asking myself if I should perform another physical exam, more blood work or perform an ultrasound,” Rawlings says. “Make sure you’ve run through those things first and, of course, have client …

It Might Be Time To Adjust Clinic Fees

April 22, 2011

Top customer service can make clients feel higher fees are worth it. Veterinarians often wonder how to adjust their fees to compensate for losses attributed to clients’ postponing pets’ annual exams and vaccine updates. Many advisers recommend re-evaluating fees annually and adjusting rates accordingly, but advise against decreasing fees across the board. Packaging services and remaining competitive on shopped-for products and services, such as spays and neuters, veterinarians can help meet their bottom lines, say certified public accountants. The consultants add that maintaining customer service is priority. “We monitored a client’s practice for four months after she decreased her fees on flea and tick products and she didn’t sell more,” says Michael Porrello, a CPA at Lacher McDonald & Co. CPAs in Seminole, Fla. “This is a common outcome when fees are reduced. The clients who would have come to the practice even without the fee reduction are just getting a better deal, while the veterinarian loses revenue. Granted, the fee reduction in this case wasn’t heavily marketed, but marketing is often an area in which practices could use an improvement.” Possible to Lose Money Experts say the economy is just the current reason being …

Nutrigenomics Takes ‘You Are What You Eat’ To New Level

February 14, 2011

Veterinary nutrigenomics combines genetics and nutrition to develop optimal diets for companion animals, a field in which researchers and pet food manufacturers are investing significant amounts of time and money. At the University of Illinois, Kelly S. Swanson, Ph.D., and his team are using DNA-based sequencing techniques to characterize the canine and feline gastrointestinal tracts. They are looking at what happens in tissue when animals are fed one diet versus another. The results may lead to a better understanding of the microbial profile and metabolic pathways of animals with varying dietary regimens and at different stages of health and life. Many questions need to be answered before the ultimate goal can be achieved: creating individual diets that make optimal use of, and even manipulate, gene expression. “The dog and cat genome sequence data is being utilized in research, taking genomic biology to gain a better understanding of dog and cat physiology and how nutrition contributes to health and disease,” says Dr. Swanson, an assistant professor of animal and nutritional sciences in the , department of animal sciences. “Genomics in pets is being used to study microbial populations and gene expression changes in blood and various tissues. …

Best Immunity

February 14, 2011

Vaccines have come a long way since the first one was developed to prevent smallpox in the 1700s. Ongoing research has resulted in continuing advancements for humans and animals alike. Many of the most recent advancements have been in the realm of feline vaccines, enough that the American Association of Feline Practitioners (AAFP) plans to appoint a committee to establish its second set of guidelines for vaccinating cats. Elizabeth Colleran, DVM, president of the AAFP and owner of Chico Animal Hospital in Chico, Calif., says her organization last published recommendations for feline vaccines in 2006. “We’re due for an update and a review of all of the protocols that were recommended then,” Dr. Colleran says. “That work hasn’t been done yet.” Establishing best practices is a work in progress even five years later. “Up until then, there weren’t any science-based guidelines,” she says. “We’re still feeling our way.” While many veterinarians rely on the recommendations of the American Animal Hospital Association (AAHA) for canine vaccines, no other major veterinary organization has issued guidelines for cats, Colleran says. She expects AAHA and other organizations to play major roles in the new AAFP guidelines. Colleran …

Fluid Therapy Can Be Lifesaver If Done Right

January 17, 2011

Incorrectly determining that a patient is dehydrated when it is hypovolemic can cost the animal its life. This leads some professionals to stress the need for caution when prescribing fluids to small animals and for a possible review of a veterinarian’s fluid therapy protocol. “My primary concerns with the way fluids are administered to patients include incorrect volumes being given and improper selection of fluid type,” says Wayne E. Wingfield, DVM, Dipl. ACVS, Dipl. ACVECC, a professor emeritus of emergency and critical care medicine at Colorado State University. “Secondly, too much emphasis on use of subcutaneous fluids is given. Failure to properly assess electrolytes and lack of understanding of acid base in relation to electrolytes and fluid needs is also a problem,” says Dr. Wingfield, also a consultant for Abbott Animal Health. The lack of a step-by-step protocol for administering fluids is one reason missteps occur, says Elisa Mazzaferro, DVM, Ph.D., Dipl. ACVECC, of Wheat Ridge Animal Hospital in Wheat Ridge, Colo. “I see a lot of animals in need of fluid therapy, often referred to me by other practices,” Dr. Mazzaferro says. “Sometimes practices stabilize the animal before transferring it, other times they immediately …

Diabetes Emergency Preparedness As Important As Insulin

October 18, 2010

Owners often are shell-shocked when they hear their pet has diabetes. But a veterinarian’s optimistic attitude can help a client successfully manage the disease. “It’s usually a traumatic piece of information for an owner when a veterinarian tells them their pet has diabetes,” says Randy Lynn, DVM, a technical service veterinarian with Intervet Schering-Plough Animal Health of Summit, N.J. “If the owner is handling the news well, you can discuss the emergency situations that may occur in a diabetic animal. If you’re speaking to them and their eyes gloss over, you might want to send them home with written information, and then have the owner return in a day or two once they’ve processed everything. “It’s a delicate balance that the veterinarian has to weigh. If you tell them too much on day one, you could tip them over the edge.” Dr. Lynn says a diabetes diagnosis gives veterinarians a “chance to shine,” noting that owners will rely heavily on them for information on choosing insulin, injecting insulin and monitoring the animal. Besides hearing the diabetes news, distressed clients also have to be warned about hypoglycemia, the No. 1 emergency concern of veterinarians who …
