Pituitary apoplexy in clinically nonfunctioning pituitary adenomas: experience of a single center

Karagiannis Apostolos , Boufas Dimitrios , Tzioras Konstantinos , Seretis Andreas , Vryonidou Andromachi

Introduction: Generously supported by IPSEN)-->Clinically nonfunctioning pituitary adenomas (CNFPA) represent 25–50% of all pituitary lesions. They may be asymptomatic and discovered incidentally or they may be diagnosed due to visual impairment or symptoms of pituitary hormone insufficiency. There is little data on apoplexy frequency in the CNFPA.The aim of our study was to assess the frequency of CNFPA a...

Relationship of benign thyroid disorders with histological alterations of breast tissue. (Preliminary results of an observational study conducted in Greece)

Angelousi Anna , Zapanti Evangelia , Prokopiou Maria , Kouraklis Grigorios , Kontzoglou Konstantinos

Introduction: The association of thyroid disorders including autoimmune thyroiditis with the risk for breast cancer is controversial (1–4). A recent study found that triidothyronine (T3) levels are positively associated with breast cancer specific mortality (5). Experimental studies have shown that T3 mimics the effects of estrogen in human breast cell lines and induces the expression of progesterone receptors (6).Purpose: The ...

Atrial natriuretic peptide (ANP) attenuates lipid peroxidation in anesthetized atherosclerotic male rabbits by reduction of renin-angotensin-aldosterone system (RAAS) activity

Kallaras Konstantinos , Karamouzis Michael , Stergiou-Michailidou Vassiliki , Zaraboukas Thomas

Reactive oxygen species (ROS) are involved in the pathogenesis of atherosclerosis. Atrial natriuretic peptide (ANP) reduces thioredoxin in heart failure patients, whereas adrenomedullin, acting as an antioxidant, protects rat cardiomyocytes from infarction and mouse vascular smooth muscle cells from angiotensin II (AII) oxidative effect. Besides AII, aldosterone (Aldo) is also an activator of ROS. Aim of the study was the investigation of the eventual antioxidant effect of ANP...

Medullary thyroid carcinoma: a case report on the efficacy and safety of combined treatment with Vandetanib and Lanreotide Autogel

Kalantzi Athanasia , Papanastasiou Labrini , Charalabidou Liana , Lyberopoulos Konstantinos , Kounadi Theodora

Introduction: Treatment options for progressive metastatic unresectable medullary thyroid carcinoma (MTC) include tyrosine kinase inhibitors (TKIs) or somatostatin analogues (SSA), although the efficacy of the latter is debatable. In such cases, combined treatment of TKIs and SSAs has not previously been reported.Aim: To present a metastatic MTC case successfully treated with a combination of Vandetanib and Lanreotide Autogel.Case ...

Administration of high dose vitamin E in female rabbits with hypercholesterolemia increases acutely androgen levels: an animal model study

Vlachos Ioannis , Chatzi Sofia , Kontzoglou Konstantinos , Boutzios Georgios

Introduction: Only few studies were observed, supporting the hypothesis that the administration of high doses of vitamin E in people with elevated serum total cholesterol levels leads to increased adrenocortical hormone secretion. There are only limited data concerning androgen or estrogen levels. The aim of this study is to investigate the possible effect of Vitamin E on adrenal and sex hormones in rabbits with hypercholesterolemia, as an animal model for the research.<p ...

Hobnail variant of papillary thyroid carcinoma, a systematic review and meta-analysis

Spyroglou Ariadni , Kostopoulos George , Bramis Konstantinos , Tseleni Sofia , Toulis Konstantinos , Mastorakos George , Konstadoulakis Manousos , Vamvakidis Kyriakos , Alexandraki Krystallenia

Background: Although papillary thyroid carcinoma (PTC) is considered to have an excellent prognosis, some more aggressive variants have been identified that show reduced overall survival rates. Besides from the diffuse sclerosing, tall cell, columnar cell, and solid variant, the hobnail variant was newly recognized as one of these aggressive forms, affecting recurrence, metastasis, and overall survival rates.Methods: We performed a systematic review and ...

Early menopause is associated with increased risk of arterial hypertension: A systematic review and meta-analysis

Anagnostis Panagiotis , Theocharis Patroklos , Lallas Konstantinos , Konstantis Georgios , Mastrogiannis Konstantinos , Bosdou Julia , Lambrinoudaki Irene , Stevenson John , Goulis Dimitrios

Objective: Menopausal transition has been associated with an increased risk of cardiovascular disease (CVD), mainly attributed to atherogenic dyslipidaemia, central obesity and insulin resistance. Whether arterial hypertension (AH) also contributes to menopause-associated CVD is currently unknown. The aim of this study was to systematically investigate and meta-analyze the best available evidence regarding the association between early menopause (EM) and AH risk.<p class="...

Calcium homeostasis in women with non-metastatic breast cancer with osteoporosis after a single-dose of denosumab: a pilot study

Mandanas Stylianos , Toulis Konstantinos , Mathiopoulou Lemonia , Margaritidou Efterpi , Georgopoulos Konstantinos , Boudina Maria , Chrisoulidou Alexandra , Pazaitou-Panayiotou Kalliopi

Introduction: Women with non-metastatic breast cancer form a distinct subpopulation in which calcium homeostasis in response to treatment with denosumab has not been extensively investigated.Methods: Female patients with osteoporosis, who were eligible for treatment with denosumab, were prospectively enrolled (2011–2012) and divided into two groups; Group A consisting of patients with either no history or benign diseases non affecting bone metabolis...

A patient with an adrenal adenoma and pituitary and intracranial meningiomas due to an ARMC5 mutation

Papadimitriou Kasiani , Tsitsimpis Anastasios , Moustaki Melpomeni , Rigana Maria , Kalogeris Nikolaos , Barkas Konstantinos , Nastos Konstantinos , Stratakis Constantine , Vryonidou Andromahi

Introduction: Armadillo-containing repeat protein 5 gene (ARMC5) is a tumor suppressor gene expressed in different human tissues. Inactivating germline and somatic mutations of the gene are involved in the pathogenesis of primary bilateral macronodular adrenocortical hyperplasia (PBMAH). These mutations are mainly met in the familial form of PBMAH and are associated with a more severe Cushing Syndrome, meningiomas and T-cell immune response defects. However, the role of ARMC5 ...

The role of parathyroid hormone monitoring after total thyroidectomy in predicting post-thyroidectomy related hypocalcaemia

Athanassiou Evangelos , Christodoulidis Gregory , Hatzitheofilou Constantinos , Tepetes Constantinos , Zacharoulis Demetrios , Tzovaras George , Euthymiou Manthos

Objective: Clinically apparent hypocalcaemia following total thyroidectomy occurs in 20–25% of patients subjected to total thyroidectomy, in 2-4% of these patients the hypocalcaemia is permanent. Treatment by per-os or iv administration of calcium supplements and vitamin D is suggested when the serum calcium concentration falls bellow a critical level, either before or whenever the patients develop clinical symptoms of tetany. The purpose of this study is to evaluate the ...
