To establish the prevalence of spondyloarthropathies among the indigenous population of Chukot Peninsula, a one-stage cross-sectional study was made with a direct medical examination of the natives of the two settlements of Eastern Chukot Peninsula: Sireniki and Novo-Chaplino where the main part of Eskimos live. During expedition, 640 natives aged over 6 years lived in both settlements (382 and 258 respectively). 464 persons (72.5%) were examined. ⋯ The incidence of ankylosing spondyloarthritis among Eskimos amounted to 0.9%, Reiter's syndrome to 0.5%, and undifferentiated spondyloarthropathies to 0.5%. Thus the one-stage expedition examination of the indigenous population of Chukotka Peninsula (Eskimos and Chukchi) has shown that diseases belonging to the group of spondyloarthropathies are widely prevalent among Eskimos.

Review Case Reports Comparative Study
[The characteristics of iron metabolism in B12-deficient anemias (an evaluation of the functional status of megaloblastic erythropoiesis)].
The review of the literature data and the evidence obtained on 85 own patients with B12-deficiency anemia concerning iron metabolism underlie 3 variants proposed by the authors: pronounced manifestations of secondary sideroachresia before B12 therapy, utilization iron deficiency upon B12 introduction, dimorphic anemia (development of megaloblastic erythropoiesis in prior iron deficiency). The causes of megaloblastic erythropoiesis incompetence (slow rate, hemolytic component, secondary sideroachresia) are discussed.
