Endothelin-1 Activates Phospholipases and Channels at Similar Concentrations in Porcine Coronary Arteries

Objective: Sensitivity of endothelin-1 (ET-1)-ion channel interactions has been proposed to exceed that of ET-1-phospholipase activation in vascular smooth muscle. We wanted to determine whether short-circuiting ion channels with staphylococcal alpha-toxin pores would shift the ET-1-force relation to the right as predicted from the above proposal.

Effects of Glucocorticoid Therapy on Urine Protein‐to‐Creatinine Ratios and Renal Morphology in Dogs

Objective: Glomerulonephritis has been associated with exogenous glucocorticoid administration and spontaneous hyperadrenocorticism in the dog. The purpose of this study was to determine the effects of long-term glucocorticoid therapy on urine protein:creatinine ratios (UP/Cs) and renal morphology.

Giant Cell Variant of Malignant Fibrous Histiocytoma in Dogs: 10 Cases (1986-1993)

Objective: Signalment, tumor sites, clinicopathologic, radiographic, and ultrasonographic features, as well as treatment protocols and survival information, were evaluated for 10 dogs with a histologic diagnosis of giant cell variant of malignant fibrous histiocytoma. Common clinical findings included subcutaneous masses, weight loss, anorexia, and lethargy.

Acute Thallium Toxicosis in a Dog

Objective: A Doberman Pinscher was evaluated for acute onset of gastroenteritis, characterized by anorexia, hematemesis, and hematochezia. The dog had ingested mole bait containing thallium 2 days prior to admission. Thallium toxicosis was confirmed by detection of thallium in the urine, using colorimetric analysis. The dog responded well to administration of antibiotics, fluids administered IV, warm-water enemas, and oral administration of activated charcoal slurries.

Internal Medicine

What Is A Veterinary Internal Medicine Specialist?

A board certified veterinary internal medicine specialist is a licensed veterinarian who has obtained intensive, additional training in understanding how your pet's internal body systems function and in diagnosing and treating the many serious diseases that can affect the health of those systems. An internal medicine specialist has advanced training in the following disciplines:  

  • Endocrinology
  • Cardiology
  • Gastroenterology
  • Hematology (study of the blood)
  • Immunology
  • Infectious Diseases
  • Nephrology/Urology
  • Neurology
  • Respiratory Diseases
  • Oncology

While your general practitioner veterinarian can diagnose and treat many health problems, certain diseases and conditions require the care of a doctor who has had specialized, intensive training in internal medicine in order to provide the very best outcome for your pet.

*Within the discipline of veterinary internal medicine, there are also veterinarians who specialize further in Small Animal Medicine, Cardiology, Neurology, and Oncology.

Why Does My Pet Need A Veterinary Internal Medicine Specialist?

Just as your own primary care physician may feel the need to refer you to the care of a specialist from time to time, your general practitioner veterinarian may feel your pet needs a specialist to help diagnose or treat a particularly complicated medical problem. While your general practitioner veterinarian can handle many aspects of your pet's care, just as in human medicine, there is sometimes a need for the attention of a specialist. You can be assured that a veterinarian who knows when to refer you and your pet for more specialized diagnostic work or treatment is one that is caring and committed to ensuring that your pet receives the highest standard of medical care for his or her problem.

While in some cases, your veterinarian may be able to simply consult with a specialist about your pet's care, in other cases it is necessary to actually refer you and your pet to the specialist for more advanced diagnostics and treatment. Board certified veterinary internists may also have access to specialized diagnostic or treatment tools that a general practitioner veterinarian may not have.

What Health Problems Does A Veterinary Internal Medicine Specialist Treat?

Board certified internal medicine specialists are trained to treat the most serious diseases and health problems that affect pets. They are also especially prepared to care for pets that may be facing multiple health problems. Thanks to better health care, more and more pets are living longer lives. As a result, an increasing number of older pets, just like older people, are coping with multiple disease states that can be very difficult to manage. For example, a cat with diabetes may also be suffering from kidney failure, or a dog in heart failure may also be diagnosed with cancer. Internal medicine specialists are uniquely prepared to oversee the care of these complicated cases. In other situations, a younger animal may develop a problem that used to be considered untreatable but is now manageable and perhaps even curable.

Here are some common diseases that frequently lead general practitioner veterinarians and concerned pet owners to seek the expertise of a specialist:

  • Cancer
  • Heart Disease
  • Gastrointestinal Diseases
  • Diabetes Mellitus
  • Immune Related Disorders
  • Kidney Dysfunction

Why Can't I See an Internal Medicine Specialist All the Time?

In some cases you can. In many practices, the 'general practitioner' veterinarian at a practice is also a boarded internal medicine specialist. General practice veterinarians, however, are also highly educated medical professionals who must meet ongoing continuing education requirements throughout their professional careers in order to maintain their licensure. When a specialist is needed, he or she is only a phone call or a visit away.

Will My Regular Veterinarian Still Be Involved?

In many cases, your regular veterinarian will still supervise your pet's veterinary care, especially if your pet is coping with multiple disease states or conditions. In other cases, your referral doctor will take over the majority of your pet's medical care. It depends on your pet's particular disease and health problem.

Did You Know?

There are approximately 1400 board certified veterinary internal medicine specialists in the United States, and the number is growing.
