Use of MRI in the neurologic patient

In contemporary veterinary medicine, magnetic resonance imaging (MRI) is an important tool in the diagnosis of neurological problems.

Conservative treatment of atlantoaxial subluxation in canine patients

Dec 1, 2005

In a recent article [ME Havig et al.: Evaluation of non-surgical treatment of atlantoaxial subluxation in dogs: 19 cases (1992-2001) in JAVMA, Vol. 227, No. 2, July 15, 2005], it was suggested that non-surgical treatment (neck-brace application) of acute atlantoaxial subluxation (AAS) carries a good long-term outcome in about 62 percent of the cases. The success rate of surgical treatment was cited as a 61-91 percent in the same paper.

Relevance of Bartonella henselae seropositivity in the feline patient

Sep 1, 2005

Bartonella henselae is a gram-negative bacterium that is most commonly associated with a self-limiting febrile condition in the cat lasting for two to three days. It has been suggested that bartonellosis is an arthropod transmitted disease, and there is an increased prevalence of the disease among flea-infested feral cats, especially kittens. Bartonellosis is a zoonotic disease and immunosuppressed humans such as people with HIV, those undergoing chemotherapy, or children, are particularly at risk. The route of transmission is mainly cat scratch or bite (SJ. Ettinger, EC. Feldman: Textbook of Veterinary Internal Medicine, 6th ed. Vol. 1, Pg 702).

Rabies update for practicing veterinarians

Apr 1, 2005

An owner showed up at a general practice in Florida with a 4-week-old kitten in a box that she had found in a golf cart. She took the kitten home and let her children play with it. Her primary complaint was that the kitten violently bit her and her children. How would you handle this case? At the clinic, the veterinarian did not let her take the kitten out of the box. Instead, he advised her to call animal control immediately. Days later, it turned out that the kitten was positive for rabies. In this case, the veterinarian saved his staff from exposure to rabies.

The definitive diagnosis of GME rests with CNS histopathologic sampling.

Measurements of blood-lactate levels help in assessing critically ill patient

Jan 1, 2005

Under aerobic conditions, the intermediate product of glycogenolysis, pyruvic acid, follows an aerobic glycolysis pathway and eventually participates in the Citric-acid cycle or "Krebs cycle" that provides substrates (16 H+) for the oxidative phosphorylation. This oxidative phosphorylation provides a large amount of energy for the cells. Under anaerobic conditions, pyruvic acid follows a different route, the anaerobic glycolysis pathway, and the end-product of this complex cascade of reactions results in accumulation of lactate.
