The spread of rickets among the children's population of Kazan

Over the past ten to fifteen years, attention to rickets has increased significantly and its study has revived. If at the first Congress of Pediatric Doctors rickets was presented by the only, though very interesting report of Dr. M. about Mr. a, then already in the proceedings of the III and IV Congresses we find that much more attention was paid to it, a temporary working classification was adopted to account for the incidence of rickets and a questionnaire for the examination of children for rickets. Unfortunately, this questionnaire appeared in print after most of this work had been done. Reports on the work on the study of the pathogenesis and clinic of rickets are found in the literature both Russian and foreign more and more often (Dombrovskaya, Vlasov, Lepsky, Combu, Gyorgy, and many others). At the same time, the literature that takes into account the spread of rickets among the children's population, especially among the population of our Union, is very few. Antonov definitely calls rickets a social disease. True, not all authors agree with him in this regard (Kuskov, Kisel, Feldman, Strelzhbitsky), but if we pay attention to the huge% of rickets among children of the first two years of life, which is indicated in the works of many authors (according to Zhukovsky, for example, 95%) and the impact that rickets has on the overall health of the team, we will have to fully agree with him.
