Hemangiosarcoma: Look for endothelial precursors as sign
February 1st 2006Canine hemangiosarcoma (HSA) is an incurable tumor of vascular endothelial cells. HSA accounts for 7 percent of all cancers; thus, of the 65 million pet dogs living in the United States today, between 1.5 million and 2.5 million could get HSA and succumb to it. Although dogs of any age and breed are susceptible to HSA, it occurs more commonly in dogs beyond middle age and in breeds such as Golden Retrievers, German Shepherds, Portuguese Water Dogs and Skye Terriers. The estimated life-time risk of HSA in Golden Retrievers is one in five, illustrating the magnitude of this problem.
A toast to Chablis, Even in death, the nutsabouts' bond might be a little too tight
February 1st 2006One day last month, I was cruising along a winding, two-lane country road when I noticed a man jogging up the street in the opposite direction. A moment later, I saw a lady walking briskly along a crossroad. She was wearing earphones and apparently listening to her favorite music as she waddled her way to fitness. Within the next few minutes, I counted six more people running, walking or exercising outdoors. This adds up to a strange set of circumstances for a wintry Sunday afternoon in eastern Pennsylvania. I wasn't surprised though. You see, it was Jan. 1, New Year's Day, and all those people had undoubtedly resolved to slim down and get fit during 2006.
Fooling Mother Nature: Induction of estrus and ovulation in mares
February 1st 2006There 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.
Life's lessons remain a powerful teacher
February 1st 2006The clinical investigation team comprising our Nephrology/ Urology Center meets daily to discuss progress that has been made, problems that need solutions and plans for the day. Before we end our discussion, we take turns sharing words of wisdom. One of my favorite topics falls under the theme called "What lesson's have you learned?"
AVMA to establish broad welfare principles

An Interview with... Dr. Jane Armstrong
February 1st 2006Veterinarians must get involved in government, says this professor and researcher. "Without our frontline involvement in everything from public health to animal welfare policies, others will make decisions on issues that veterinarians are most qualified to decide."
Correction: Idiosyncrasies in greyhounds that can affect their medical care (February 2006)

Osteoarthritis in cats: Still a mass of unknowns
February 1st 2006When addressing arthritis in cats, we presume similarities to arthritis in dogs, interpreting radiographs and clinical signs with canine differential diagnoses in mind. And we develop therapies based on how dogs are managed. But these presumptions have little scientific basis. In fact, we know little about how many cats have arthritis, what effect their arthritis has on their lifestyles, or to what degree therapy improves their comfort level.
