Polycystic ovary syndrome (PCOS) is now globally recognised as the most common endocrinopathy in women of reproductive age and has a prevalence of 5-21% depending on the criteria used (NIH, Rotterdam or Androgen Excess Society). What is special about the syndrome is its dual entity involving both the reproductive and metabolic profile of the women affected. As a result, any intrinsic or extrinsic factors affecting both these components, could lead to pathophysiological alterat...

Introduction: Hypoglycemia consists a significant problem in insulin treated type 2 diabetic patients. The present study compared the incidence of hypoglycemic episodes in type 2 diabetics between continuous glucose monitoring/CGM vs self monitoring of blood glucose/SMBG.Methods: Seventeen patients with type 2 diabetes underwent a 24 h CGM for a period of 3–5 consecutive days. At the same period they recorded their glucose values using SMBG from fou...

Introduction: The aim of this study was to systematically review the literature for studies that have investigated possible differences in prevalence of subclinical Cushing’s syndrome (SCS) and related clinical implications between patients with unilateral (UAI) and bilateral adrenal incidentalomas (BAI) and to meta-analyze the best evidence available.Methods: Electronic databases PubMed, MEDLINE and EMBASE were systematically searched. Main study o...

Objective: The clinical phenotype of PCOS includes reproductive and hormonal aberrations. Visceral adiposity index (VAI) is an indicator which could connect hyperandrogenism and anovulation. The objective was to evaluate the relationship between VAI, menstrual disorders and hormonal, biochemical and ultrasound parameters in women with PCOS.Patients: 180 women with PCOS diagnosed with Rotterdam criteria.Measurements: We correlated V...

Objective: Conflicting findings have been published regarding the pressure wave reflection and the arterial stiffness in young women with PCOS as opposed to the overt ab initio presence of endothelial dysfunction compared with controls which can be reversed six months after metformin administration. The aim of this study was to investigate arterial stiffness and wave reflections in young women with polycystic ovary syndrome (PCOS) with respects to the different weight...

Introduction: AGEs have been shown to be accumulated in granulosa cell layer from human ovaries in normal and in women with polycystic ovarian syndrome (PCOS) and insulin resistance. AGEs interfere with insulin signaling pathways of several target tissues and are implicated in insulin resistance mechanisms. There is evidence that within the ovary these pathways are also important for glucose metabolism and normal folliculogenesis. The effect of human glycated albumin (HGA) eit...

In insulin resistant, young women with PCOS elevated serum AGEs and their receptor RAGE have been reported. The present study (approved by the local ethical committee) was undertaken to determine whether increased levels of serum AGEs in PCOS is a distinct finding compared with age- and BMI-matched women, presenting the isolated components of the syndrome and whether serum AGE levels were different among PCOS phenotypes. A total of 193 lean non-insulin resistant women were stu...

The present study aimed to investigate whether dietary advanced glycation end-products (AGEs) are detected in the ovarian tissue of normal female rats and whether they affect metabolic or hormonal profile.Normal rats were randomly assigned to regular diet, high (H-AGE) or low (L-AGE) content for 6 months. Age-matched rats fed with regular diet served as controls.H-AGE rats, demonstrated higher levels of fasting glucose (P&#6...

Introduction: Glycogen storage disease type Ia is a rare genetic disorder that develops due to deficient activity of the enzyme glucose 6-phosphatase and manifests clinically early in life with hypoglycemia and failure to thrive, as well as with organ dysfunction, due to excess glycogen accumulation, including hepatomegaly and kidney dysfunction. Endocrine manifestations are commonly encountered in these patients. However, due to their rarity, endocrine dysfunction has not bee...

Introduction: Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumors arising from neuroendocrine cells in the endocrine and central nervous system, the natural history of which remains inadequately understood. Large epidemiological studies are gradually emerging from different countries worldwide, which contribute to the establishment of a spherical view about these tumors. The purpose of this study is to evaluate the epidemiological, clinical and pathological cha...
