Background: Graves’ disease (GD) typically manifests as an autoimmune hyperfunction of both thyroid lobes. Less than 10 cases of unilateral GD have been described, and the pathophysiology of unilateral GD remains unknown. Co-existence of malignancy has never been reported. We report a case of GD of the left lobe with simultaneous discovery of a papillary carcinoma within the hyperfunctioning lobe.Case description: A 49-year-old patient of Middle-Eas...

Background: Anti-Müllerian Hormone (AMH) and Antral Follicle Count (AFC) are both principally used as markers of ovarian reserve and available in all UK hospitals. The utility of these markers in the binary diagnosis of Polycystic Ovarian Syndrome (PCOS) by published criteria, such as Rotterdam, has been previously reported. We evaluated their utility in the evaluation of oligo/amenorrhoea in healthy young non-obese women.Methods: Women with both ov...

Introduction: Type 1 diabetes mellitus (T1DM) is associated with reduced bone mineral density (BMD) and increased bone turnover. However, data regarding the influence of glycemic control on bone are limited. The aim of this study was to evaluate BMD and bone remodeling markers in patients with T1DM in relation to changes in glycemic control.Methods/design: We studied 107 patients with T1DM (Group-D) (mean age: 34+8.1 years, M/F: 48/59) and 95 healthy con...

Introduction: Papillary thyroid microcarcinomas (PTMC) are usually considered low-risk tumors with favorable prognosis. However, a small percentage behaves aggressively and controversies exist for various prognostic factors. The aim of this study was to evaluate demographic and tumor specific characteristics related to PTMC invasiveness.Patients – methods: This is a retrospective study of 510 thyroidectomized patients with PTMC who were treated in t...

Introduction: 21-hydroxylase deficiency (21-OHD) is a common inherited disorder accounting for 90–95% of congenital adrenal hyperplasia (CAH) cases. Some cases may be diagnosed in adulthood after the incidental discovery of adrenal masses on computerized tomography (CT).Case report: A 59-year-old male was investigated for incidentally discovered bilateral adrenal masses in an abdomen CT scan, measuring 5 cm on the right and 8 cm on the left adrenal....

Introduction: Although patients with type 2 diabetes mellitus (T2DM) have normal or higher bone mineral density (BMD) comparing to healthy subjects, they appear to be at high risk of osteoporotic fractures. Factors that contribute to bone fragility in T2DM are not clearly understood. The aim of this study was to evaluate the influence of glycemic control on bones in T2DM.Methods/design: We studied 40 patients with T2DM (mean age: 54.3+3.2 years, M/F: 24/...

Introduction: Insulin-like growth factor-I (IGF-I) has a role in cell proliferation, differentiation, migration, and survival. By alternative splicing different IGF-I mRNA transcripts as IGF-IEc (mechano growth factor, MGF) or IGF-IEa variants are produced. MGF induces muscle hypertrophy and implicated in the pathophysiology of various types of cancer. Aim of the study was to investigate the role of MGF in the pathophysiology of neuroendocrine neoplasms (NENs).<p class="ab...

Introduction: Polymorphisms of the receptor for advanced glycation end products (AGEs), RAGE, have been associated with autoimmune disorders and their complications. There are no studies concerning Hashimoto’s thyroiditis (HT); the aim of our study was to investigate the possible role of two RAGE polymorphisms (−429T>C, −374T>A) in combination with indices of oxidative status in women with HT.Design: We examined 300 euth...

Background: Kisspeptin stimulates gonadotropin secretion indirectly by stimulation of hypothalamic GnRH neurons. Kisspeptin and kisspeptin receptor, a G-protein coupled receptor (GPCR), are also expressed in the human ovary, but their direct actions on ovary, if any, are unclear.Objectives: To examine the direct actions of kisspeptin on granulosa lutein cells (GL cells) and the role of kisspeptin in steroidogenesis.Materials and me...

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...
