[Radiographic criteria of differential diagnosis of hereditary tubulopathies in children]. / Rentgenologicheskie kriterii differentsial'noi diagnostiki nasledstvennykh tubulopatii u detei.

In search for x-ray signs of skeletal involvement specific for each type of hereditary tubulopathies, the authors analyze the results of clinical and x-ray examinations of 144 children aged 2 to 16. Vitamin D-resistant rickets which was diagnosed in 83 children was found to be characterized by varus deformations of the lower limb bones, by systemic osteoporosis of various degrees with hypertrophy of the osseous beams in the epimetaphyseal compartments and accelerated bone age. In renal tubular acidosis diagnosed in 28 children the most typical findings were valgus deformation of the lower limb bones, an appreciable deceleration of bone age, systemic osteoporosis with thinning of osseous beams, the degree of bone deformation being the minimal or moderate. In 20 children with the de Toni-Debre--Fanconi disease the most frequent finding were valgus deformations of the lower limb bones, osteoporosis with drastic thinning of osseous beams unrelated to the degree of deformations and deceleration of bone age. Vitamin D-dependent rickets diagnosed in 13 children was characterized by varus deformations of the lower limb bones, hypertrophic osteoporosis, and normal parameters of bone age. Hence, our study demonstrated the possibility and high reliability of x-ray differential diagnosis of various forms of hereditary tubulopathies in children.

[X-ray diagnosis of chronic gastritis in children]. / Rentgenologicheskaia diagnostika khronicheskogo gastrita u detei.

A comparative roentgeno-endoscopic examination made in 80 children with gastritis has demonstrated the high information content of the x-ray method of one-stage double opacification of the stomach with barium. The method is based on an analysis of the thin relief of the mucous membrane. Coincidence with the morphological diagnosis has been recorded in 85% of the cases.

[Psychoautonomic syndrome in non-infectious subfebrile conditions in children]. / Psikhovegetativnyi sindrom pri neinfektsionnykh subfebrilitetakh u detei.

To ascertain the cerebral organization and the importance of its specific levels in the occurrence of the thermopathological syndrome associated with vegetovascular dystonia, 40 children aged 8-15 years with non-infectious subfebrile conditions of long standing were examined. The children's status was marked by polysystemic shifts common to the neurogenous disorders. Of crucial significance was dysfunction of the structures of the suprasegmental level (the limbic-reticular complex) of vegetative regulation with the involvement of the specialized hypothalamic centers of thermoregulation, with excessive sympathetic influences at the periphery and formation of the psychovegetative syndrome. An individual analysis of the psychovegetative syndrome makes it possible to define the contribution of the concrete endo- and exogenous factors to the pathogenesis of non-infectious subfebrile conditions and to develop a differential approach to the treatment.
