[Errors in the diagnosis of juvenile rheumatoid arthritis].

A total of 50 adolescents with different diseases of the joints were examined. Diagnostic errors were made in 42% of the cases. Hyperdiagnosis of juvenile rheumatoid arthritis was observed in 30% of the patients and hypodiagnosis in 12%. The studies showed that the knowledge of the initial manifestations of the disease, its further course, detailed acquaintance with the features of the articular syndrome, extra-articular signs, laboratory data and their dynamics during treatment in each specific case allowed one to avoid diagnostic errors.
