Objective The frequency of thyroid nodules accompanying Graves’ disease and the risk of thyroid cancer in presence of accompanying nodules are controversial. The aim of this study was to evaluate the frequency of thyroid nodules and the risk of thyroid cancer in patients operated because of graves’ disease. Subjects and methods Five hundred and twenty-six patients in whom thyroidectomy was performed because of Graves’ disease between 2006 and 2013 were evaluated retrospectively. Patients who had received radioactive iodine treatment and external irradiation treatment in the neck region and who had had thyroid surgery previously were not included in the study. Results While accompanying thyroid nodule was present in 177 (33.6%) of 526 Graves’ patients, thyroid nodule was absent in 349 (66.4%) patients. Forty-two (8%) patients had thyroid cancer. The rate of thyroid cancer was 5.4% (n = 19) in the Graves’ patients who had no nodule, whereas it was 13% (n = 23) in the patients who had nodule. The risk of thyroid cancer increased significantly in presence of nodule (p = 0.003). Three patients had recurrence. No patient had distant metastasis. No patient died during the follow-up period. Conclusions Especially Graves’ patients who have been decided to be followed up should be evaluated carefully during the follow-up in terms of thyroid cancer which may accompany.

SummaryThe purpose of this investigation was to study the accumulation of 87mSr in the proximal parts of the femoral bones of patients treated previously by external irradiation due to cancer of the uterine cervix. It was assumed that this method may be used in the future for the early diagnosis of postirradiation changes of bone (osteoradionecrosis).The incidence of postirradiation changes of the femoral neck among 5735 patients treated between 1950 and 1961 at the Department of Gynaecology of the Institute, was 0.8%. In the early period of postirradiation changes the patients complain only of pain and limitation of physical activities. If radiological and gynaecological findings were negative, the differential diagnosis between early recurrence and early osteoradionecrosis became impossible.49 selected patients were scanned after intravenous injection of 10—115 μCi of 87mSr per kg of body weight (0.5 up to 6.0 mCi). Illustrative cases of normal pelvic bones as well as postirradiation changes are presented and discussed. The authors conclude that the findings justify further systematic studies on the morphology of accumulation of 87mSr in the bones.

SummaryThe clinical course and the haematologic events in a patient suffering from metastatic thyroid cancer after administration of 806 mCi of 131I are described. A serious bone marrow depression developed and was treated successfully. The haematological changes during the early and late phases of the radiation injury were studied in detail and compared with those after external irradiation. The haematological events after internal irradiation with 131I are characterised by initial neutrophilic leukocytosis, protracted lymphopenia, slowly developing anaemia reaching lowest values about 3 months after administration, erythroid hyperplasia in the bone marrow after recovery from bone marrow depression and prominent cytological features of the bone marrow, especially pronounced erythropoietic polyploidy.

The paper presents an example of the linear splines use to describe the photosynthesis light curves for microalgae culture. The main mathematical models of the relationship between photosynthesis rate and light are listed. Based on the previously formulated basic principles of modeling microalgae photobiosynthesis, a mathematical model is proposed that describes the dependence of the assimilation number of chlorophyll a on the value of the light flux by linear splines. The advantage of the proposed approach is a clear definition of the point of change of the limiting factor. It is shown that light-limited photosynthesis rate is determined not only by external irradiation, but also by the concentration of chlorophyll a. The light-saturated rate depends on the amount of a key enzyme complex, which limits the rate of energy exchange reactions in the cell. Verification of the proposed model on the example of the diatom microalgae Skeletonema costatum was carried out. It is shown that the higher the degree of cell adaptation to high irradiation, the better the photosynthesis curve is described by linear splines. If S. costatum cells are adapted to low irradiation, deviations of experimental data from the idealized broken line are observed, which are caused by changes in the pigment composition. When the experimental data are normalized, the cell adaptation factor is reduced, all points are described by a single broken line, which indicates the universality of the proposed approach.
