[Nosology of the fetus and child as a problem of general pathology].

Alteration is a common pathological process inherent to kymatogenesis and responsible for congenital defects which are the basic nosological unit of early kymatogenesis. Intrauterine compensatory adaptation triggers proliferation of mesenchymal tissue or hyperplasia of parenchymal cellular elements with accelerated maturation. Blastomogenesis occurs in children primarily during kymatogenesis. This fact can explain rapid progression of malignant growth during the first five years of life, the tumors being of embryonic or visceral tissue. Circulatory disorders prevail in perinatal period. They are represented by such nosological units as intrauterine hemorrhages and pneumopathies and are related to tissue immaturity. Fetal inflammation can be attributed to productive and alterative components. It is prone to generalized infection typical for early months of life. Opportunistic and viral infection is a common pathology in early infancy being the main nosological unit in this period. Later on the infection becomes local. Chronicity of infection rests upon persistent tissue immaturity.
