Introduction: Alteration in the expression of clock-related genes has been observed in various diseases. Adrenal sensitivity to adrenocorticotropic hormone (ACTH) apart from the hypothalamo-pituitary-adrenal axis is also regulated by the intrinsic adrenal clock. A link between clock genes and glucocorticoid adrenal production has been suggested by in vitro and animal studies. In the present study we investigated clock genes expression in human benign tumors of the adr...

Introduction: Noonan syndrome is a genetic disorder that usually occurs on a sporadic basis (de novo mutuations) or with autosomal dominant inheritance. Patients present with dysmorphic facial features, cardiac disorders and short stature. Delay of puberty can also be noted. We present here an adult case of Noonan syndrome.Presentation: A 25 years old male presented to our department with low stature, decreased libido and absence of any secondary sexual ...

Introduction: IGF-1 overexpression has been associated with tumorigenesis. IGF-1Ea, IGF-1Eb and IGF-1Ec isoforms were shown to be regulated differently in cancer. IGF-1Ec and IGF-1Eb overexpression has been positively associated with cell survival and proliferation in various tumors. Elevated IGF1Eb/IGF-1Ea ratio has been suggested as a biomarker of cervical cancer prognosis. Herein, we aimed to examine the expression of IGF-1 isoforms in human adrenocortical carcinomas (ACCs)...

Background: Sodium glucose co-transporter 2 inhibitors reduce the incidence of cardiovascular events in patients with type 2 diabetes mellitus based on the results of recent cardiovascular outcome studies. Herein, we investigated the effects of long-term treatment with empagliflozin on biochemical and immunohistochemical markers related to atherosclerosis development in apolipoprotein E knockout [Apo-E(−/−)] mice.Methods: At the ag...

Introduction: Postsurgical hypoparathyroidism, (postHypoP), is a common complication of total thyroidectomy. We studied the variation of biochemical and hormonal parameters in patients who underwent total thyroidectomy.Design: The study included 106 females of a mean age (±S.D.) 51.03 (±13.42) years who underwent total thyroidectomy for multinodular goiter. We estimated the value of 25(OH)vitD, PTH, CT, adjusted Ca, P, and alkali...

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...
