Introduction: The molecular pathogenesis of pancreatic neuroendocrineneoplasms (PNEN) is increasingly yet incompletely understood. PNEN typically occur sporadically or may occur within the context of hereditary tumor predisposition syndromes. PNEN can also be associated with endocrinopathy of hormonal hypersecretion. We present a young male with a multi-hormonal neuroendocrine neoplasm of pancreas.Case presentation: A 24-year-old male, non-smok...

Aim: To describe the clinical course of an adolescent girl with gigantism.Background and methodsIn young persons with open epiphyses, overproduction of GH results in gigantism, with consequent longitudinal growth acceleration1. Pituitary gigantism is extremely rare, and its cause in the majority of patients is a pituitary adenoma1. Here, we present a 12, 5 years-old girl investigated for tall stature [183.5&#1...

Introduction: Some endocrine disorders, including hypophysitis and isolated adrenocorticotropic hormone (ACTH) deficiency, are caused by an autoimmune response to endocrine organs. Previous data have also shown that isolated ACTH deficiency may be associated at least in part with a paraneoplastic syndrome. We present a rare case with isolated ACTH deficiency along with ectopic posterior hypophysis.Case presentation: A 53-yea...

Background: Adrenal venous sampling (AVS) is the gold standard method that evaluates the source of aldosterone overproduction in primary aldosteronism. During AVS aldosterone and cortisol are simultaneously measured in order to assess successful adrenal cannulation and lateralization of aldosterone overproduction. However, in patients with both adrenal cortisol and aldosterone overproduction, plasma metaneprhines and normetanephrines can be measured to overcome selectivity and...

Introduction: Limited data, support the notion that testosterone induces oxidative stress. Corticotropin-releasing hormone (CRH) participates locally in the endothelial inflammatory response by regulating the pro-oxidative mechanisms of the endothelium, inducing its adaptation to local stress. The present study was undertaken to determine whether the CRH induced pro-oxidant activity in macroendothelial cells under basal conditions, is regulated In vitro by androgen (t...

Introduction: Limited data exist on testosterone and oxidative stress induction. The present study was undertaken to evaluate, in vitro, the role of physiological concentrations of androgens (testosterone-DHT) in modulating the pro-oxidant and antioxidant activity of intact endothelial cells.Materials and methods: EA.hy926 macroendothelial cells were cultured in DMEM phenol red free without FBS for 24 hours. Growth medium was replaced and then testostero...

Introduction: Graves’ disease (GD) is an autoimmune thyroiditis frequently associated with development of Graves’ orbitopathy (GO). As a consequence, patients with GO experience impairment of quality of life (QoL) and social function. The aim of our study was to assess quality of life in patients with GO.Methods: This is a single-center observational study in an outpatient clinic of autoimmune endocrinopathies at a Tertiary, General, Universi...

Introduction: Delayed diagnosis of a cardiovascular event is related with higher case-fatality rate in women as compared to men. In fact, accumulating evidence supports an association between the menopausal status and the development of cardiovascular disease (CVD). We aimed to assess the extent of subclinical vascular disorders in young, healthy postmenopausal women, with respect to the calculated cardiovascular risk.Methods: This cross-sectional study ...

Introduction: There is a great interest in the association of thyroid hormones and mood. Although it appears to be important interactions between the central regulation of mood and the thyroid axis, the effects of antidepressants and especially of selective serotonin reuptake inhibitors (SSRIs) remain ambiguous. We investigated the thyroid function in perimenopausal women suffering from depression.Material and methods: We examined 102 perimenopausal wome...

Introduction: Hot flashes and night sweating are the most common medical complaints in women during the menopausal transition and they are strongly associated with the presence of perimenopausal depression. The pathophysiology of hot flashes has not been elucidated. Peripheral vasodilation and increase in skin temperature observed in women with hot flashes might be induced by changes in brain neurotransmitters and instability in the hypothalamic thermoregulatory center due to ...
