Introduction: IgG4 Related Hypophysitis (IgG4-RH) is a newly recognized form of hypophysitis. It usually appears as part of IgG4-Related Disease (IgG4-RD), an immune mediated disease, with manifestations in many organs. Isolated hypophysitis without other IgG4-RD manifestations is rare.Presentation: A 64 years old female referred to our department for further investigation of a 9 month history of fatigue, muscle weakness, recurrent episodes of right temp...

Introduction: Thyroid autoimmunity has been associated with the diagnosis of differentiated thyroid (DTC) cancer in surgical series. However, this finding has not been consistent in Fine Needle Aspiration Biopsy (FNAB) cytology series.Aim: We aimed to investigate the association between thyroid autoimmunity and DTC in patients who underwent ultrasound-guided FNAB.Methods: A retrospective analysis of patients who had undergone ultra...

Introduction: Adrenal Incidentalomas (AIs) have been associated with an increased risk of metabolic syndrome and dyslipidemia, though evidence regarding the latter is limited and, sometimes conflicting. Lipid abnormalities in patients with AIs have been described to be associated with subclinical hypercortisolism. Our aim was to test if lipid profile in patients with adrenal incidentalomas may predict subclinical Cushing’s Syndrome (sCS).Material an...

Introduction: Osteoporosis is a systemic skeletal disease with a strong genetic component. The androgen receptor (AR) is encoded by the AR gene and mediates the action of androgens, which play an important role in bone metabolism. Polymorphisms in the AR gene may be implicated in the pathogenesis of osteoporosis.Objectives: The present study aimed to explore the influence of the (CAG)n repeat polymorphism of AR</em...

Introduction: Transcription factor 7 like-2 (TCF7L2) gene variants (rs12255372 and rs7903146) have been consistently shown to raise genetic risk for type 2 diabetes (T2D). The aim of this study was to investigate the possible role of these variants in the development of dysglycemia (T2D or impaired fasting glucose (IFG)) in patients with metabolic syndrome (MS).Patients and methods: The study population consisted of 228 patients with MS who were...

Introduction: The cytokine tumor necrosis factor alpha (TNFα) is encoded by the TNFα gene and stimulates bone resorption. TNFα is involved in the pathogenesis of bone loss associated with estrogen deficiency. Polymorphisms in the TNFα gene have been associated with bone mineral density (BMD) in different populations.Objectives: The present study aimed to explore the influence of the single-nucleotide polymorphism <em...

Introduction: Postmenopausal virilization with acute onset and rapid progression requires a thorough investigation for the presence of adrenal or ovarian tumor. We present here a challenging case of a radiologically not visible and rare androgen-hypersecreting ovarian tumor.Case report: A 71-year old postmenopausal woman presented to our department for the investigation of terminal hair growth, of recent onset and rapid progression, on the upper lip, chi...

Introduction: The aim of this study was to examine whether the distribution of SHBG (TAAAA)n repeat variants contributes to the exposure of the female fetus to androgen excess, by influencing the, in utero, androgen availability.Methods: The study population consisted of 100 pregnant women that carried female fetuses and underwent the procedure of amniocentesis due to age (older than 35). Blood samples and amniotic fluid samples were dr...

Introduction: Aromatase is encoded by the CYP19 gene and catalyzes the conversion of androgens to estrogens, which in turn regulate skeletal homeostasis. Polymorphisms in the CYP19 gene have been studied for their association with bone mineral density (BMD) in the general population with mixed results.Objectives: To explore the influence of the CYP19 (TTTA)n repeat polymorphism on BMD and serum levels of osteoprotegerin (OPG), receptor activator...

Introduction: Sex hormone-binding globulin (SHBG) regulates the bioavailability of sex steroid hormones, which in turn regulate reproductive function. The potential association of SHBG gene polymorphisms with the age at menopause has not been examined.Objective: The present study aimed to assess the possible relationship between the pentanucleotide (TAAAA)n repeat polymorphism in the promoter of the SHBG gene and the age at menopause in a Greek fe...
