Pituitary adenomas are recognized by assessing the size of the pituitary and sella turcica, detailed study of pituitary structure and status of the sella turcica walls and the adjacent tissues. Radiodiagnosis in combination with clinical laboratory findings permit the differentiation of pituitary adenomas from other pathological processes in this gland (hyperplasia, atrophy, inflammation, and dystrophy) and from changes in the neighboring tissues (calcification of different origin, increase of intracranial pressure, etc.). For minimizing the diagnostic errors, craniography is to precede CAT or MI. CAT or MI should be carried out in the “amplification ” mode, and in difficult diagnostic cases should be repeated over time. For an experienced specialist, MI by its informative value is the method of choice for the diagnosis of pituitary diseases (adenomas, cysts, etc.).","PeriodicalId":342539,"journal":{"name":"Problems of Endocrinology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129085384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean AD for the thyroid of pregnant women was 24.09+1.17 sGy, that of prenatally exposed children 44.74+2.58 sGy. Thyroid status of 195 exposed children and 220 controls is examined. Thyroid hormones were radioimmunoassayed and measured by enzyme immunoassay using standard diagnostic kits. Serum triiodothyronine concentrations were significantly increased in prenatally exposed children of both sexes (p<0.05 for boys and p<0.01 for girls). Serum thyroxin and thyroxin-binding globulin (TBG) levels were decreased in exposed boys in comparison with the control (p<0.05). In exposed girls thyroxin levels were virtually normal, but there was a tendency to an increase of thyroglobulin (t=1.6) and to a decrease of TBG (t= 1.7) in comparison with the control. The mean TBG concentration in the serum was below the norm in both groups. The results can be indicative of thyroid dysfunction in remote periods after prenatal exposure to radioactive iodine.","PeriodicalId":342539,"journal":{"name":"Problems of Endocrinology","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130971059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For disclosing the mechanisms of GPI-PLC conjugation with insulin receptors and growth factors, we analyzed GPI hydrolysis in Rati cells and found that insulin and epidermal growth factors (EGF) activate GPI hydrolysis to IPG by 20 and 40%o, respectively (p<0.001), while specific phosphatidylinositol- 3’-kinase (PIj kinase) inhibitor vortmannin cancels this insulin and EGF effect.

The following morphological types of diseases were observed: benign nodular formations in 42 patients, thyroid cancer in 4, papillary TINO MO in 2, and follicular cancer TINO MO in 2 cases. Out of benign formations, 36 were multinodular colloid goiter and 6 follicle-cell adenomas. As a result of using IOLAS, thyroid cancer was diagnosed during surgery in 8 (17.4%) out of 36 patients with multinodular colloid goiter; this diagnosis necessitated more extensive intervention than was planned: subtotal resection had to be extended to thyroidectomy. In all the cases IOLAS data were confirmed by urgent and later planned histological analyses. Due to this method, no reoperations were needed, which previously had to be performed because of the data of planned histological analysis, and therefore, the probable complications of reoperations were prevented. Our data indicate that IOLAS more accurately identifies the type and morphology of thyroid involvement and helps choose adequate volume of intervention. The first experience with laser fluorescent study as optic biopsy holds good promise as regards improvement of intraoperative rapid diagnosis of thyroid diseases.","PeriodicalId":342539,"journal":{"name":"Problems of Endocrinology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122525198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
