We investigated the effects of long-term testosterone replacement in hypogonadal and elderly men on lipids and lipoproteins. Twenty-two men with initial serum testosterone concentrations below 3.5 ng/ml took part in the study: 11 with hypopituitarism (1st group) and 11 otherwise healthy elderly men with low testosterone levels (2nd group). Testosterone(More)
BACKGROUND The purpose of this study was to assess the advantages and disadvantages of 3D gray-scale and power Doppler ultrasound, including thin slice volume rendering (TSVR), applied for evaluation of thyroid nodules. METHODS The retrospective evaluation by two observers of volumes of 71 thyroid nodules (55 benign, 16 cancers) was performed using a new(More)
Although elastography can enhance the differential diagnosis of thyroid nodules, its diagnostic performance is not ideal at present. Further improvements in the technique and creation of robust diagnostic criteria are necessary. The purpose of this study was to compare the usefulness of strain elastography and a new generation of elasticity imaging called(More)
The aim of the study was differential evaluation of new and classical sonographic features of benign thyroid nodules and thyroid cancer with three-dimensional gray-scale sonography and evaluation of the effectiveness of the thin-slice surface rendered images in comparison with multiplanar reformation (MPR) presentation. Fifty-four thyroid nodules were(More)
A majority of incidentally found adrenal tumors derive from the adrenal cortex. The aim of our study was evaluation of the incidence of chromaffin tumors in a group of 1,111 patients with adrenal incidentalomas. In this group there were 803 women and 308 men, aged 10-87 years. Clinical examination, imaging studies (ultrasound scans, CT, and MRI if(More)
In order to evaluate the role of beta-endorphin in the pathogenesis of obesity and essential hypertension 44 subjects were investigated: 12 nonobese hypertensives, 11 obese hypertensives, 11 obese normotensives and 10 normal subjects. Plasma concentrations of beta-endorphin and cortisol were measured by radioimmunological and ACTH by immunoradiometric(More)
In order to evaluate the GH/insulin-like growth factor-I (IGF-I) axis in the polycystic ovary syndrome (PCO), 21 women aged 18-38 yr were studied. The GH responses to the GH-releasing hormone (GHRH), and plasma concentrations of IGF-I were measured in seven obese women with PCO, seven obese healthy controls without PCO, and in seven nonobese subjects. Total(More)
In order to establish the role of insulin in the pathogenesis of lipid abnormalities in hyperandrogenic women with the polycystic ovary syndrome (PCO) 49 women aged 18 to 35 yr with a normal glucose tolerance test were studied. They were divided into two groups: 27 women with PCO (9 obese and 18 nonobese), and 22 healthy women (12 with simple obesity and 10(More)
In order to investigate the effect of chronic hypercortisolaemia on endogenous natriuretic factors (atrial natriuretic hormone (ANH) and the Na+/K+ pump inhibitor) digitalis-like substance (DLS), and their relation to hypertension, 28 patients with pituitary- or adrenal-dependent Cushing's syndrome and six patients on high-dose prednisone treatment were(More)
In order to evaluate the effect of postmenopausal estrogen replacement therapy on the plasma levels of the insulin-like growth factor-I (IGF-I) 12 postmenopausal women aged 44 to 59 years were studied. The control group consisted of 15 healthy premenopausal women aged 20-44 years. In the postmenopausal women the plasma levels of IGF-I, gonadotrophins and(More)
