Surgery STAT: CPSS surgery and aftercare
April 1st 2008Congenital portosystemic shunts usually are single vessels that develop inside or outside the liver (Photo 1). Because these vessels carry blood around the liver instead of through it, the normal hepatic processes of metabolism, storage and production are disrupted. Most animals with congenital portosystemic shunts (CPSS) present with mild to moderate clinical signs that are not life-threatening. The most critical component for their long-term treatment is restriction of dietary protein to reduce substrates for ammonia formation by colonic bacteria. Diets for dogs with CPSS should be 15 percent to 20 percent protein on a dry-matter basis, readily digestible, high in zinc and vitamin E, and low in manganese. Sources of gastrointestinal hemorrhage (gastritis, parasites), which provide additional protein substrate, should be treated. Ammonia production and absorption can be reduced by administration of lactulose, antibiotics such as neomycin or metronidazole, or unflavored yogurt with active cultures. Cystitis..
Oral melanoma: Improving dogs' survival
April 1st 2008It is not often that one is able to bear witness to a sea change. The veterinary community has, in my opinion, seen one with the development of the melanoma vaccine. This unique form of therapy, a DNA-based vaccine, would justify my opinion, but the successful collaboration between veterinary oncologists, human oncologists and the pharmaceutical industry also serve to mark this event as extraordinary.
Letters: Providing the right fluids in patients with hypernatremia
April 1st 2008In the January 2008 issue, the article "Toxicology Brief: Sodium hypochlorite bleach ingestion in two dogs" states that lactated Ringer's solution was used to treat hypernatremia and hyperchloremia. It seems that a fluid such as dextrose 5% in water may be more appropriate, as well as something without sodium to replenish bicarbonate.
Medical error and liability: How technology can be a safeguard
April 1st 2008As discussed previously, the emergence of a "reasonable physician" standard of care affects both human and veterinary practitioners, defining our approach to error management. Under this standard, adverse events previously defensible by deference to custom might now result in decisions of negligence if it is determined that such events were easily preventable.
2 states on guard against EEE, West Nile
March 27th 2008Boston - 3/27/08 - Health officials in Massachusetts and New Hampshire already are preparing to go on the attack this summer against mosquitoes that cause Eastern equine encephalitis (EEE) and West Nile virus, because of several localized cases in both states during the last three years.
Mind over matter, and test results
March 26th 2008The next morning started as all those before it, with my cell phone ringing to inform me it was time to get out of bed. The unwelcome sound is the single part of my day that I never look forward to, even if it could be signaling that this is the day my husband and I will become homeowners.
