Diagnostic cut-off values for the urinary corticoid:creatinine ratio for the diagnosis of canine Cushing's syndrome using an automated chemiluminescent assay.

Background: Cushing's syndrome is one of the most common endocrinopathies in dogs. The preferred screening test for spontaneous Cushing's syndrome is the low-dose dexamethasone suppression test (LDDST). The diagnostic value of urinary cortisol:creatinine ratios (UCCR) is questionable.

Establishment of the European College of Veterinary Clinical Pathology (ECVCP) and the current status of veterinary clinical pathology in Europe.

After 5 years of development, the European College of Veterinary Clinical Pathology (ECVCP) was formally recognized and approved on July 4, 2007 by the European Board of Veterinary Specialisation (EBVS), the European regulatory body that oversees specialization in veterinary medicine and which has approved 23 colleges. The objectives, committees, basis for membership, constitution, bylaws, information brochure and certifying examination of the ECVCP have remained unchanged during this time except as directed by EBVS. The ECVCP declared full functionality based on the following criteria: 1) a critical mass of 65 members: 15 original diplomates approved by the EBVS to establish the ECVCP, 37 de facto diplomates, 7 diplomates certified by examination, and 5 elected honorary members; 2) the development and certification of training programs, laboratories, and qualified supervisors for residents; currently there are 18 resident training programs in Europe; 3) administration of 3 annual board-certifying examinations thus far, with an overall pass rate of 70%; 4) European consensus criteria for assessing the continuing education of specialists every 5 years; 5) organization of 8 annual scientific congresses and a joint journal (with the American Society for Veterinary Clinical Pathology) for communication of scientific research and information; the College also maintains a website, a joint listserv, and a newsletter; 6) collaboration in training and continuing education with relevant colleges in medicine and pathology; 7) development and strict adherence to a constitution and bylaws compliant with the EBVS; and 8) demonstration of compelling rationale, supporting data, and the support of members and other colleges for independence as a specialty college.

Distribution and morphology of skeletal muscle lesions after experimental restraint stress in normal and stress-susceptible pigs.

Six normal and 22 stress-susceptible (SS) pigs were subjected to experimental restraint stress to test the hypothesis that SS pigs are more affected by stress-induced skeletal muscle lesions than normal pigs. The stress was provoked by a 12 min intravenous infusion of the myorelaxant succinylcholine at a dose which induced leg paralysis. At necropsy 2-3 days after the stress, 24 muscles were examined macro- and microscopically.

Serum auto antibodies and clinical/pathological features in German shepherd dogs with a lupuslike syndrome.

This study presents 8 dogs of German Shepherd breed (6 males, 2 females, 2-5 years of age at onset of the disease) with a lupus like syndrome characterized by febrile polyarthritis, wasting, nephropathy, cutaneous lesions and high positive titres of ANA (antinuclear antibodies) of speckled type. The serum autoantibodies were further characterized by double immunodiffusion against ENA (extractable nuclear antigen), ELISA for Histone antibodies (Histon fraction H-24A and H-3S), indirect IF on rat-liver sections, non treated and RNase/DNase digested sections for DNP/RNP antibodies, and smears of a hemoflagellate C. luciliae for antibodies vs doubbel strained DNA, (dsDNA).

Serum creatine kinase activity as a selection criterion for stress susceptibility after standardised stress in pigs.

Estimation of serum creatine kinase isoenzyme activity was used as a selection criterion for stress sensitivity in pigs 8-12 weeks of age, classified for stress susceptibility as positive to halothane anaesthesia. Standardized stress was provoked by administration of adrenocorticotropic hormone or synstigmine. The experiments were performed under experimental conditions in permanently catheterized animals and in a field trial.
