COMPARATIVE CHARACTREISTICS OF METHODS OF CONNECTIVE TISSUE DYSPLASIA DIAGNOSIS IN CHILDREN
The article compares different authors' methods of diagnosis of connective tissue dysplasia in children on the basis of phenotypic and visceral markers. The benign joint hypermobility syndrome in children of different ages in Tver was diagnosed using the Beighton method: it was detected in 71% of children under 7 years old and in 31.1% of older children. The benign joint hypermobility syndrome is typical of practically all children from 3 to 4 years old and of the majority of children from 5 to 7 years old, which indicates that increased flexibility is a physiologic standard for this age and that the Beighton method does not detect accurately the abnormality of connective tissue in children under 7 years old. 120 children have been examined for presence and severity of connective tissue dysplasia using three different ways at the same time and also using different authors' methods and diagnostic tables. The method of T.I. Cadurina detects presence of connective tissue dysplasia 1.5 times more often than the methods of T. Milkowska-Dimitrova and A. Karkashov. The results when using the method of L.N. Abbakumova are in between. The conclusion of the article shows that diagnosis of connective tissue dysplasia in children cannot be based only on identification of the benign joint hypermobility syndrome, and the methods of diagnosis of connective tissue pathology taking into account not only external but also internal markers are more accurate. Common methods of calculating frequency of connective tissue pathology in children must be applied in all regions of our country.
