[Clinico-morphologic comparisons in the combined study of the thyroid gland]. / Kliniko-morfologicheskie sopostavleniia pri kompleksnom issledovanii shchitovidnoi zhelezy.

The authors conducted radionuclide and ultrasonic scanning (RNS and USS) of 92 patients with thyroid nodal lesions (colloid goiter, adenoma, cyst, thyroiditis and cancer). The results obtained were correlated with those of surgical intervention and histology findings. The combination of RNS and USS of the thyroid made it possible to accurately define the site, sizes, function and internal structure of a node. Analysis of combined scanning has shown that the term "warm" node does not reflect its function. Cystic-hemorrhagic degenerative changes develop more frequently in nodes exceeding 3.5 cm in diameter. To a lesser degree, these changes are associated with the morphological structure of a node. The authors have arrived at a conclusion that combined radiation diagnosis of thyroid cancer at its early stages is difficult in the absence of characteristic diagnostic signs. Additional diagnostic measures including fine-needle biopsy, are recommended in such cases.

[Teaching roentgenology to students at a medical institute]. / Prepodavanie rentgenologii studentam meditsinskogo instituta.

The system of teaching roentgenology at the I.M. Sechenov First Moscow Medical Institute is described. The authors point to several reasons for which some rearrangement of teaching roentgenology in medical institutes is required. This type of rearrangement seems possible at the expense of intensive and skilled teaching without adding extra lessons in the curricula. The authors provide various forms of the presentation of lectures describe organizational stages in the optimization of practical studies and consider in detail the system of teaching roentgenology with the help of special programs based on the principle of programmed teaching. They also outline the prospects of further studies in the pedagogical process and possible ways of its improvement.
