Background: To identify a serum prolactin (PRL) cut-off value indicative of a PRL-producing adenoma in women with polycystic ovarian syndrome (PCOS) and hyperprolactinaemia and characterize such patients. Materials and methods: In the present retrospective case–control study, the medical records of 528 PCOS women were reviewed. Pituitary magnetic resonance imaging (MRI) was performed in PCOS patients with PRL levels ≥94.0 ng/ml and/or symptoms suspicious of a pituit...

Background: 25 hydroxy vitamin D (25(OH)D) vitamin levels are positively associated with bone mineral density and season, time of day and sun exposure duration influence its synthesis. Variations in daylight throughout the year and zenith angle, depending on the latitude of residence, influence u.v. solar radiation which is closely related to serum 25(OH)D levels. The aim of this study was to investigate the degree of seasonal variation of 25(OH)D serum levels in a population-...

Background and objectives: Medullary thyroid carcinoma (MTC) originates from thyroid C-cells and is a calcitonin (CT) secreting tumour with aggressive behaviour. Surgery is recommended in all patients with basal or calcium-stimulated CT values of 100 pg/ml or higher due to the high probability of MTC. The objective of this study was to investigate the utility of calcium stimulation test for CT in order to distinguish MTC from C-cell Hyperplasia (CCH) preoperatively and to exam...

Introduction: Diagnostic and post-therapy radioiodine whole body scan (WBS) is used in the follow-up of differentiated thyroid carcinoma (DTC) for the detection of local recurrence or remote metastasis. We report a case of false-positive uptake of radioiodine WBS.Case report: A 37-year-old female patient underwent subtotal thyroidectomy for multinodular goitre and histology revealed multifocal papillary thyroid carcinoma, of follicular type with three fo...

Introduction: The aim of this study was to evaluate predictors of metabolic disease in normal weight postmenopausal women.Patients and Methods: This cross-sectional study included 457 non-obese postmenopausal women, recruited from the Menopause Clinic of Aretaieio Hospital, National and Kapodistrian University of Athens. The diagnostic criteria of the International Diabetes Federation for the definition of Metabolic Syndrome were used, in order to classi...

Introduction: Recent evidence reports a controversial extra-gonadal role of follicle stimulating hormone (FSH). Conflicting data support that the association between FSH and obesity might be maintained by a direct or even indirect effect to the adipose tissue. The aim of this study was to evaluate the associations between FSH concentrations and various obesity indices in women after menopause.Patients and Methods: This cross-sectional study included 420 ...

Introduction: The hypothalamic-pituitary-ovarian and/or adrenal axis as well as the autonomous nervous system affect significantly the intensity of menopausal symptoms Pre-existing levels of stress may affect the individual perception of menopausal symptoms. We aimed to evaluate the efficacy of a structured stress management program to reduce levels of stress and severity of climacteric symptoms, in a sample of middle-aged Greek women.Methods: The sample...

Introduction: The coexistence of papillary thyroid cancer (PTC) and medullary TC (MTC) is rare. Previous retrospective studies have shown a prevalence up to 19%. The aim of our study was to assess the prevalence of PTC in patients with sporadic MTC.Methods: This is a single-center retrospective study of an endocrinology outpatient clinic at a Tertiary, General, University Hospital. Patients who had undergone total thyroidectomy with central neck compartm...

Introduction: Low levels of 25-hydroxy-vitamin D [25(OH)D] have been recognized as a new cardiovascular disease risk factor. Conflicting data exist regarding the effect of statins on 25(OH)D levels and glucose metabolism.Methods/design: This was an open-label randomized prospective comparative study evaluating the effects of atorvastatin and rosuvastatin at equivalent doses on 25(OH)D levels, glucose homeostasis and systemic inflammation in non-diabetic ...

Introduction: The polycystic ovary syndrome (PCOS) is a common and complex disease without a clear pattern of inheritance. There is evidence that PCOS is affected by both genetic and environmental factors, but there is no single and unambiguous explanation for its pathogenesis. Anti-Müllerian-inhibiting hormone (AMH) has an inhibitory effect on FSH-stimulated follicle growth and it has also been shown that serum AMH levels are higher in women with PCOS than in normovulato...
