The measurement of biomarkers that reflect cartilage breakdown is a powerful tool for investigating joint damage caused by disease or injury. Particularly in cases of osteochondrosis, synovial concentrations of these biomarkers may reveal the presence of osteoarthritic changes. Coll2-1, Coll2-1 NO2 and myeloperoxidase have recently been introduced in equine osteoarticular research but comparison between the concentrations of these markers in OCD affected and healthy joints has not been made. Therefore, this study aimed at reporting the synovial concentrations of these biomarkers in joints affected with osteochondral fragments in the tarsocrural joint compared to unaffected joints. Myeloperoxidase and Coll2-1NO2 revealed to have similar levels between affected joints and controls. However, in contrast to previous studies using C2C the present study demonstrated that synovial levels of Coll2-1 were significantly elevated in tarsocrural joints affected with osteochondrosis. Thus, Coll2-1 may be an earlier marker of cartilage degeneration than other cartilage degradation markers that have been previously used in equine medicine.

Background: Atypical myopathy (AM) is an acute, severe rhabdomyolysis occurring in grazing horses. Since In the beginning of October 2009, a new outbreak affects started in several European countries. Geographic, demographic and clinical data of the reported cases in the month October 2009 are described. Key Findings: The survival rate over the month October 2009 was 25%. The most frequently observed clinical signs were congestedive mucous membranes, dyspnea, tachycardia, depression, weakness, stiffness, recumbency, trembling, transpirationsweating, and myoglobinuria. Non-survivors were significantly more often likely to be recumbent than survivors. Prognostic factors, symptomatic treatment and preventive measures are discussed. Significance: Slight differences were encountered during the described outbreak of AM in October 2009 compared to previous studies. Equine practitioners should be alert aware that previous epidemiological studies have shown that after a high prevalence this autumn, for new cases are likely to occur in the upcoming spring 2010.
