ABSTRACT
We report herein the results of the cross-cultural adaptation and validation into the Russian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Russian CHAQ CHQ were fully validated with 3 forward and 3 backward translations. A total of 146 subjects were enrolled: 86 patients with JIA (23% systemic onset, 39% polyarticular onset, 15% extended oligoarticular subtype, and 23% persistent oligoarticular subtype) and 60 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Russian version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA.

Some sera of tumor patients render a blocking effect on the activity of autologous and allogenic T lymphocytes in blasttransformation test to PHA and spontaneous rosette-formation. The activity that block spontaneous rosette-forming reaction is directed against the population of postthymic peripheral lymphocytes but not that of thymocytes. No correlation was found between the serum activity, which block RSP and RBT, and antibodies to PHA, lymphocytotoxins, C-reactive protein and the rheumatoid factor.

By means of a micromethod of lymphocytotoxic test the content of eleven HL-A antigens (1, 2, 3, 5, 7, 8, 9, 10, 11, 12 and 13) was studied in 200 healthy human subjects, 100 patients with rheumatoid polyarthritis and 82 patients with bone tumors. The latter included 50 patients with benign tumors (osteoblastoclastomas, chondroblastomas, chondromas, non-osteogenic fibromas) and 32 patients with malignant tumors (chondro- and osteosarcomas, Ewing sarcoma, malignant osteoblastoclastomas). It was found that in patients with different bone tumors antigen HL-7 was encountered reliably more frequently than in control groups, in patients with malignant tumor also antigen HL-A10 was more often detected. The most frequently observed haplotyes in oncological patients were HL-A3/7 and HL-A2/7. In patients with rheumatoid polyarthritis antigen HL-A3 was found more rarely and antigen HL-A10 more frequently than in healthy subjects. The most frequent haplotypes in this group were as follows: HL-A2/7, HL-A2/8 and HL-A11/12. The possible mechanisms of the relationship between HL-A antigens and the development of pathology are discussed. Some considerations are offered concerning the possibility to utilize HL-A typing for an accessory differential diagnosis.
