Intra- and interobserver variability of ultrasonographic measurements of the thyroid gland in healthy Beagles
The variability of three different parameters (the maximal length, width, and height) within observer, between observer, and between dogs was assessed based on three different measurements made by each of three observers in five healthy beagles. The height and the volume had the lowest intra- and interobserver variability, while measurements of the length had the biggest intra- and interobserver variability.
Pathology of bartonella endocarditis in six dogs
Features of Bartonella endocarditis included a combination of fibrosis, mineralization, endothelial proliferation, and neovascularization with variable inflammation. None of these features is specific; however, the combination is distinct both from endocarditis caused by culturable bacteria and from endocardiosis. Ultrastructural analyses revealed both extracellular and intraendothelial bacteria. Clinical history, serology, and PCR are currently necessary to establish an etiologic diagnosis of Bartonella endocarditis.
Colostrum management in calves: effects of drenching vs. bottle feeding
A slightly delayed increase of serum immunoglobulin concentration (approximately 3 h) was obvious in drenched calves compared with bottle-fed calves, but drenched calves reached significantly higher immunoglobulin concentrations compared with bottle-fed calves. It is concluded that the proper application of colostrum by a drencher is a useful method for adequate colostral supply in newborn calves.
Associations Between Pregnancy Outcome and Serological Response to Neospora caninum Among a Group of Dairy Heifers
Heifers that were seropositive to N. caninum by ELISA had a much greater risk of abortion than seronegative heifers. Most seropositive heifers showed evidence of a reactivation of infection during pregnancy.


Risk/Benefit Of MRIs For Animals With Head Trauma; Considerations For Anesthesia In Head Trauma Patients
With regard to anesthesia (and head trauma), some things should jump into your mind immediately. Mortality rates skyrocket when cerebral perfusion is compromised in head trauma patients. Cerebral perfusion pressure is the mean arterial blood pressure minus intracranial pressure (CPP=MABP-ICP). When you place a head trauma patient under general anesthesia, I think it is important to minimize anything that will decrease cerebral perfusion pressure.
Morphine In Local Dental Blocks
There is some evidence that inflammatory pain (as would presumably exist in and around a tooth that needs pullin') leads to up-regulation of mu opioid receptor mRNA in the dorsal root ganglia and brainstem, resulting in increased axonal transport of peripheral opioid receptors to the terminal ends of sensory afferents. As this tends to be a body-wide phenomenon, I can't think of a good reason why it wouldn't happen in the mouth as well.
Dog Has Developed Several More Bladder Stones In Only A Few Months
Although the facts that this is a Schnauzer and that there are multiple stones both hint toward the new stones being calcium oxalate, you must culture the urine. If it's a urea-splitter, then start appropriate antibiotics and a dissolution diet (S/D), and continue both until the stones are gone.
Client Information: How To Pick A Good Dog/Cat Breeder
I would love to hear from VINners about what advice to give clients about buying a dog or cat from a breeder.
