title: [Endocrinologic and pathologic findings in ornamental birds with polyostotic hyperostosis].
abstract: Polyostotic hyperostosis is a finding that is often seen on x-rays in companion birds. Hyperestrogenism might be a causative for polyostotic hyperostosis. The purpose of this study was to compare endocrinologic and pathologic findings in birds with polyostotic hyperostosis. Thirty-five affected and three control birds were examined. Blood samples were taken for endocrinologic statement (estrone, estradiol, testosterone and estrone sulfate) and the values were compared with the pathologic findings. In the present study the comparison of endocrinologic and pathologic findings did not reveal any significant results supporting the hypothesis that polyostotic hyperostosis was caused by hyperestrogenism.
