OBJECTIVE Metabolic syndrome (MetS) is a cluster of metabolic abnormalities with insulin resistance (IR) as a major component. It has been recently questioned whether MetS and its related components are associated with functional and morphological alterations of the thyroid gland. The aim of our study is to examine thyroid volume and nodule prevalence in a(More)
Insulin resistance is a major feature of type 2 diabetes mellitus, obesity and nonalcoholic fatty liver disease (NAFLD). Several studies pointed out the possible role of increased leptin in NAFLD in humans. The aim of this study is to determine the effect of metformin on plasma leptin levels in obese patients with type 2 diabetes mellitus and NAFLD compared(More)
Fungal pathogens are increasingly encountered after renal transplantation. Aspergillus causes significant morbidity and mortality in transplant patients. Fungal thyroiditis is a rare occurrence owing to unique features of the thyroid gland. Most cases are caused by Aspergillus species and have been described in immunocompromised patients. Presentation may(More)
Studies evaluating the effect of estrogen replacement therapy (ERT) on leptin levels are contradictory. The aim of this study was to investigate effects of bilateral ovariectomy and ERT on serum leptin levels and anthropometric measurements as well as interaction among leptin, sex hormone binding globulin (SHBG), and insulin like growth factor-I (IGF-I) in(More)
OBJECTIVE The aim of this study was to investigate the effects of metformin on thyroid volume and nodule size. SUBJECTS AND METHODS Prospective data were gathered on 100 newly diagnosed subjects with insulin resistance (68 female, 32 male) between August 2008 and May 2010. Each subject followed a standard diet and exercise program, and received 1,700(More)
Approximately 30% of patients with thyroid nodules have indeterminate or suspicious fine-needle aspiration (FNA) biopsy results. These patients usually undergo thyroidectomy because of cancer risk. Our aim was to determine diagnostic value of cyclin A and cyclin B1 immunohistochemistry added to routine cytology and their expression on histological sections.(More)
OBJECTIVE To describe a case of isolated adrenocorticotropic hormone (ACTH) deficiency associated with thyroid autoimmunity, subclinical hypothyroidism, and transient hyperprolactinemia. METHODS We present a detailed case report, including results of laboratory studies and magnetic resonance imaging, and discuss potential contributing factors in this(More)
Glomerular disease often accompanies a wide variety of liver diseases, including acute or chronic hepatitis. A striking association between hepatitis B virus and glomerulonephritis particularly membranous glomerulonephritis has been reported by various authors. It is not surprising, therefore, that hepatitis C virus (HCV) infection has been recently(More)
BACKGROUND Serum thyroglobulin (Tg) is the key parameter used in the follow-up of subjects with differentiated thyroid cancer (DTC). Current guidelines advise its measurement to take place when Thyrotropin (TSH) levels are >30 µU/ml (stimulated Tg) and when TSH < 0.1 µU/ml (suppressed Tg). Although stimulated Tg levels <1 ng/ml have been shown to display(More)
