Introduction: Primary adrenal insufficiency (PAI) can be of autoimmune origin (AI), non-autoimmune origin (bilateral adrenalectomy, acute hemorrhage, infection) (NAI) or pharmaceutical (mitotane) origin. Studies have shown that these patients develop long-term morbidities and increased mortality due to excessive glucocorticoid tissue exposure. Data about differences concerning hydrocortisone (HC) needs, cortisol hormonal levels and metabolic parameters in these patients are sc...

Background: The aim of the study was to assess the clinical features of gastric neuroendocrine neoplasms type 1 (GNEN1).Methods: We have analyzed the clinical data of the first 73 patients with GNEN1 from our registry.Results: The mean age(±S.D.) of the patients (51 (68.9%) females) and the mean follow-up were 55±12.3 years and 28.8±42.2months, respectively. All patients had sporadic tumors and all wer...

Introduction: Ephrin receptors (EPHs) have a role in tumor growth, invasion, angiogenesis and metastasis of several neoplasms. Aim of the study was to investigate the expression and possible clinical significance of EPH-A4 and EPH-A2 protein expression in the pathophysiology of neuroendocrine neoplasms (NENs).Methods: EPH-A4 and -A2 protein expression was assessed by immunohistochemical analysis along with Ki-67 proliferation index (%) on 28 paraffin emb...
