Skin elastic fiber pathology and idiopathic scoliosis.

An antomic study of skin elastic fibers coupled with a histochemical and ultrastructural study of one peripheral muscle sample was performed in 34 patients with idiopathic scoliosis. Twenty-eight of them had an elastopathy resulting in rupture or disparity between the dermis elastic fibers. The muscle histoenzymologic study showed that 17 of the patients also had an abnormal predominance of type I muscle fibers.

[Lack of correlation between frozen shoulder and HLA-B27 (author's transl)].

HLA-B27 antigen is strongly correlated with ankylosing spondylitis and several other rheumatic diseases. However, data concerning frozen shoulder are contradictory. Bulgen reported an increased frequency of HLA-B27 which was not observed by Noy.
