Introduction: Neuroendocrine neoplasms (NENs) are neoplasms with a slow progression and a 5-year survival 77–95%. It is well known that secondary deposits of NENs may dedifferentiate during the natural history of the disease, presenting a more aggressive biological behaviour.Aim of the study: The prevalence of secondary foci dedifferentiation of pancreatic NENs (p-NENs).Methods: From the NENs database of 414 patients, 160 (38....

Introduction: Several studies have suggested that patients with acromegaly have an increased risk of thyroid, colorectal, breast and prostate tumors. We determined the prevalence of malignant neoplasms in patients with acromegaly in a single Greek Centre during the years 1995–2015.Methods: We evaluated cancer risk in a cohort of 110 patients (M/F 48/62, age 58.63±13.8 years, range 30–86) with acromegaly. Mean age at diagnosis of acromegaly...

Sodium glucose co-transporter2 (SGLT2) inhibitors reduce the incidence of cardiovascular events in patients with Type 2 Diabetes Mellitus (T2DM) based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with canagliflozin on biochemical and immunohistochemical markers related to atherosclerosis and atherosclerosis development in the aorta of Apolipoprotein E knockout (Apo-E(−/−)) mice. After...

Background: Primary thyroid lymphoma (PTL) is a rare thyroid malignancy. Nevertheless, it frequently presents diagnostic and therapeutic challenges. We describe two patients with PTL with different clinical presentation/clinical picture and outcome.Patients and methods: Two female patients underwent total thyroidectomy, the first, a 67-year-old female patient, because of nodular goitre and the second, a 79-year-old female patient, because of a large, pai...

Introduction: Differences in the prevalence and prognosis of cardiovascular disease have been linked with gender specific risk factors as well as the differential impact of sex hormones. Moreover, specific genetic polymorphisms may increase further the risk of cardiovascular disease development. Polymorphisms of genes encoding the NADPH/NADPH oxidase system and the endothelial nitric oxide synthase (eNOS) have been associated with atherosclerosis in the general population, but...

Purpose: High serum homocysteine (HCY) and indirectly deficiency of folate and/or vitamin B12 stimulate bone resorption and adversely affect collagen cross-linking. The aim of this study was the evaluation of serum levels of HCY, folate and vitamin B12 in patients with Paget’s disease of bone (PDB) and the effect of zoledronic acid (ZOL) on their serum levels.Methods: This was a prospective open-label cohort study, with a control arm at baseline. Ni...

Objectives: Neurofibromatosis type 1 (NF1) is an autosomal, dominant, genetic disorder. The genetic lesion in neurofibromatosis type 1 is located at locus 17q11.2 that harbors the neurofibromin gene. Patients have 3-4 times higher possibility to develop malignancies relative to the general population. The endocrine manifestations of neurofibromatosis include precocious puberty, short stature, osteoporosis and pheochromocytoma. We present a patient with neurofibromatosis type 1...

IntroductionMenopausal transition has been associated with an increase in cardiovascular risk, which is possibly linked with the hormonal imbalance following ovarian senescence. Both insulin levels and circulating androgens (FAI) have been associated with endothelial dysfunction, through studies evaluating flow mediated dilation (FMD). We aimed to investigate whether the link between these hormones and FMD might be explained by markers of oxidative stres...

Introduction: Liraglutide treatment reduces cardiovascular complications in patients with diabetes mellitus (DM), which may imply a favorable impact on the endothelial function. The aim of the present study was to investigate in vitro the effect of liraglutide on endothelial redox balance and the parallel expression of CRH, UCN1, 2 and 3 neuropeptides, under normoglycemic and hyperglycemic conditions.Methods: Macroendothelial cell line EAhy926 w...

Background: Incidence of non-functioning pituitary macroadenoma (NFPMA) is very rare in pregnancy. We describe a case of complicated non-functioning pituitary macroadenoma presented during pregnancy. 26 year old female at 21 weeks gestation presented to emergency services with worsening headaches, nausea and vomiting for 2-3 months. This was associated with transient double vision and confusion since 2 days. She was admitted to emergency department 3 weeks ago with vomiting an...
