Introduction: Patients diagnosed with DTC have excellent prognosis. A small percentage of patients with disease persistence do not respond to treatment with RAI (RAI-refractory DTC) and have low median survival (3.5 years). We investigated the prognostic factors and the disease course in patients with RAI-refractory DTC.Methods: Of all DTC patients (n=1160) followed-up in our department in recent years, 800 received RAI treatment and were classified in 2...

Background: Anabolic androgenic steroids (AAS) are widely used to improve performance and/or enhance appearance. The aim of this study was to assess the impact of AAS on the reproductive system of athletes.Methods: An electronic literature search was conducted, using the databases MEDLINE, CENTRAL, Scopus and Google Scholar. Studies including AAS use in any type, dose, form or duration of intake were included in the review. Main outcomes were AAS effects...

Objective: Simultaneous occurrence of MTC and DTC is frequently found. It is unclear whether there is a common pathogenic mechanism. Aim of our study was to characterize clinical features of MTC when coexisting with DTC.Methods: Of 273 MTC patients followed-up in our department 39 (14.3%) had MTC simultaneously with DTC. They were divided in 4 subgroups according to size. Clinical histopathological data were recorded.Results: The p...

Introduction: Solid cell nests (SCNs) of the thyroid are considered embryological remnants of the ultimobranchial bodies and the thyroid diverticulum. They are frequently (61–89%) detected in the thyroid gland, but their biological significance remains disputable. According to the fetal cell thyroid carcinogenesis hypothesis SCNs may act as a source for specific thyroid cancer stem cells generating distinct thyroid cancer phenotypes. We report a case of a patient with con...

Background: Pulmonary carcinoids (PC) are rare neuroendocrine tumors (NETs). The course of PCs is considered to be indolent, but patients with advanced disease have low survival rates and their treatment options are limited. As PCs are under-represented in trials, therapeutic decisions are based on evidence extrapolated from other types of NETS. Capecitabine-Temozolamide (CAPTEM) has demonstrated significant efficacy in pancreatic NETs. However, its role in PCs is still unexpl...

Introduction: Obstructive Sleep Apnoea (OSA) is more common in women with Polycystic Ovary Syndrome (PCOS). There is paucity of data regarding the impact of OSA in women with PCOS.Methods: We conducted a retrospective study using electronic patients’ records of premenopausal women with PCOS who were first seen in the weight management clinic (WMC) between March/2008 and November/2014. PCOS diagnosis was documented either by referring clinician or es...

Aim: Patients with thyroid nodules, usually undergo FNA, prior to considering surgery however the results may not be conclusive. Our aim is to compare the cytology results in patients who have had two FNA’s with post-operative histology.Methods: All patients who have had thyroidectomy and two pre-operative FNA’s over 7 years were identified. Post-operative histology and FNA cytology was collected from pathology records. Standard ‘Thy’...

Purpose: Available data associate lipids concentrations in men with BMI, anabolic steroids, age, and certain cytokines. Data are less clear in women, especially across the full adult lifespan, and when segmented by pre- and postmenopausal status.Methods: Subjects: 120 healthy women in Olmsted County, MN, USA, a stable well studied clinical population. Dependent variables: measurements of 10-hr fasting high-density lipoprotein cholesterol (HDL-C), total c...

Introduction: CLOCK system is a highly conserved, ubiquitous molecular ‘clock’ which creates internal circadian rhythmicity under the influence of light/dark information. CLOCK system is regulated by the coordinated activation/inactivation of several transcription factors, including the CLOCK, the BMAL1 and other essential regulators, such as the Pers, Crys and RORs. The present study aimed to evaluate the circadian rhythm of clock-related genes expressed in patients...

Bone is involved in both phosphate-calcium and energetic metabolism. Osteocalcin, secreted by the osteoblasts, stimulates insulin secretion and improves insulin sensitivity. FGF-23, secreted by the osteoclasts, increases phosphate urinary excretion and is a marker of insulin resistance. Relationship between insulin-resistance, body fat and bone metabolism remains unclear. Therefore, the aim of this study was to evaluate osteocalcin and FGF-23 levels in diseases differing by bo...
