Diagnostic significance of the Buchstab-Yasinovsky reaction in rheumatic children

The diagnosis of rheumatism, despite its apparent simplicity, often presents great difficulties for the doctor. In particular, the initial forms of heart damage, which do not manifest themselves as either noises or joint damage, often remain unrecognized, and we fix our attention on them only when we have a detailed picture of endocarditis. Meanwhile, on an outpatient appointment, we often have children with joint pain without objective phenomena from the articular apparatus and the cardiovascular system.
