Introduction: Adrenal incidentalomas (AIs) are increasingly detected due to the widespread use of abdominal imaging for diagnostic purposes. AIs are usually benign non-functioning adenomas but few prospective studies exist regarding their evolution.The aim of this study was to investigate the morphological and hormonal changes of AIs in a cohort of patients with long-term follow-up.Materials and methods: This was a prospective obse...

Introduction: Pseudohypoparathyroidism (PHP) constitutes a heterogenous group of disorders characterized by end-organ resistance to parathyroid hormone (PTH), due to a defect in the stimulatory G protein-activated cAMP formation. PHP type Ib is characterized by renal resistance to PTH, without the phenotypic features of Albright hereditary osteodystrophy (AHO).Case report: A 31-year old woman was referred to our clinic for investigation of severe hypocal...

Introduction: Recombinant parathyroid hormone 1–34 (PTH(1–34)) and 1–84 (PTH(1–84)) stimulate new bone formation and are associated with significant decrease in the risk of vertebral and non-vertebral fractures. De novo autoimmune hepatitis (AIH) is a rare graft dysfunction occurring in patients having undergone liver transplantation (LT) for causes other than AIH.Case report: A 61-year old woman was referred to our metabolic b...

Introduction: There is indirect evidence of unfavorable effects of parathyroid hormone (PTH) on glucose metabolism. Teriparatide (recombinant human PTH 1-34 - TPTD) has been recently available for the treatment of osteoporosis.Aim: To evaluate the acute and chronic effect of TPTD on blood glucose and insulin levels in women with established osteoporosis.Patients and methods: Twenty-three postmenopausal women with established osteop...

Introduction: Acromegaly is a chronic disease associated with impairment of quality of life (QoL) and psychological status. The aim of the present study was to assess QoL and mood disturbance in patients with acromegaly.Description of methods/design: It was a comparative, cross-sectional study conducted in the department of Endocrinology at a tertiary medical centre of northern Greece in 2011. AcroQoL questionnaire was used to assess QoL in acromegalics ...

Introduction: Acromegaly is characterized by high cardiovascular morbidity and mortality. Oxidative stress and endothelial dysfunction are underlying mechanisms of atherosclerosis. The aim of this study was to evaluate the blood redox status and endothelial function by means of nitric oxide (NO) levels in patients with acromegaly.Description of methods/design: Total antioxidant capacity (TAC), catalase activity and glutathione concentration (GSH), as mea...

Introduction: Antithyroid drugs (ATD) remain the first-line therapy in patients with Graves’ disease (GD), despite high relapse rate. The purpose of the present study was to identify predictors of long term remission of GD in patients who received ATD as primary treatment.Description of methods/design: We restrospectively identified patients with Graves’ disease initially treated with ATD between 1984 and 2011 and extracted relevant data from t...

Introduction: Subclinical hypothyroidism (SH) is associated with increased risk for atherosclerosis, mainly attributable to dyslipidemia, diastolic hypertension, altered coagulability and increased levels of inflammation markers. However, conflicting data exist regarding the effect of L-thyroxine substitution on these parameters.The purpose of the present study was to quantify the effect of L-thyroxine therapy on lipid profi...

An association between testicular function and vasoconstrictive peptide endothelin-1 levels, which is produced by Leydig and Sertoli cells, is observed. Endothelin –1 regulates blood flow in the testis and stimulates testosterone secretion.The purpose of this study is (1) to estimate the influence of tamoxifene and raloxifene therapy on enthothelin-1 levels in men of reproductive age with idiopathic hypogonadism. (2) To find an association between i...

Introduction: Fine Needle Aspiration Biopsy (FNA) is a method widely used in the assessment of thyroid nodules. The main aim of this 18-year retrospective study was the investigation of the diagnostic value of FNA in the approach of thyroid malignancy.Subjects and methods: patients underwent 1938 FNAs from 1987 to 2004 in the Department of Endocrinology, ‘Hippocration’ General Hospital, Thessaloniki, Greece. 178 of these patients subsequently u...
