Introduction: Cushing’s syndrome results from increased or aberrant expression of ACTH, CHR, or neuroendocrine receptors that leads to uncontrolled hypersecretion of cortisol. The most common cause is ACTH-secreting pituitary adenomas. Alternatively, the glucocorticoid excess may be due to adrenal neoplasia or to ectopic ACTH – secreting tumors. There are rare reports of patients with a meningioma secreting CRH presenting paraneoplasic Cushing’s syndrome.<p ...

Aim: To analyze the effects of inositol administration on parameters related to glucose homeostasis.Material and methods: Systematic review and meta-analysis of articles published in Medline or Web of Science Until February 1, 2016. We included studies that met the following criteria: i) Randomized controlled clinical trials of inositol/inositol isomer supplementation against placebo in parallel design, ii) performed in humans, iii) with information abou...

Introduction: Sheehan syndrome (SS) is caused by postpartum necrosis of the pituitary gland, associated with significant haemorrhage during or after delivery. It is rare in developed countries, but still frequent in underdeveloped ones. We present a rare presentation of this syndrome.Clinical case: A 48 years old black woman presented at the emergency department for long term fatigue and dyspnea that worsened a few days before. Her physical examination r...

Introduction: Chronic somatotropin (ST) hypersecretion has systemic effects. It can cause important structural and functional cardiovascular (CV) changes, which can result in increased morbidity and mortality.Case report: A 48-year-old, male. followed by cardiology since 2005 for dilated cardiomyopathy (DCM) (Ecocardiography: moderately dilated left ventricle with globular appearance. Severely impaired global systolic function - LVEF 25%. Right cavities ...

Although primary hyperparathyroidism (PHPT) is usually cured by surgery, some individuals are unable to undergo parathyroidectomy and are refractory to standard calcium lowering medical therapy. In such cases, targeted therapy with cinacalcet may be useful.The aim of this study was to access the short-term efficacy of cinacalcet in lowering calcium (Ca2+) levels in patients with PHPT unable to undergo parathyroidectomy and refractory to standa...

Introduction: There is a lack of epidemiological data on the distribution of haptoglobin and C677T of MTHFR polymorphisms in Caucasians type 2 diabetic patients. The contribution of these two genetic factors to hyperhomocysteinemia and hypercysteinemia can be useful to prevent cardiovascular events and to reduce public health costs. The aim of this study is to evaluate the contribution of haptoglobin and C677T polymorphisms for hyperhomocysteinemia and hypercysteinemia in Port...

Introduction: Giant prolactinomas are rare tumours, representing 2–3% of all prolactin (PRL)-secreting tumours. Their definition is restricted to pituitary adenomas with a diameter ≥4 or ≥2 cm of suprasellar extension, very high PRL concentrations (≥1000 ng/ml) and no concomitant GH or ACTH secretion. They are more common in young to middle-aged men. Endocrine symptoms are often present for a long period of time, but most times the diagnosis is made when...

Insulin autoimmune syndrome (IAS) is a very rare cause of hypoglycaemia in western countries. One proposed mechanism is anti-insulin antibody capture of prandial insulin followed by the dissociation of insulin from anti-insulin antibody. The first objective was to study the relationship between glucose, insulin and C-peptide during a prolonged glucose load in two patients with active IAS. The second was to study the variation of these parameters between the active and the reco...

Introduction: Amiodarone is an antiarrhythmic iodine-rich drug, known to induce thyroid dysfunction both due to its high iodine content and through amiodarone-induced thyrotoxicosis (AIT), being this latter process classified into three different types. Type 1 is associated with increased thyroid hormone synthesis; type 2 is a destructive process with thyroid hormone release and type 3 is thought to be a mixture of the former two. Since treatment options are different, there h...

Introduction: Scientific progress allowed an evolution on the therapeutic of diabetes mellitus. Continuous subcutaneous insulin infusion therapy (CSII) is one good example, but, beside patients motivation little is known about other psychological factors of success in this therapeutic and how they contribute to quality of life (QoL).Objectives: Determining some psychopathological predictors of CSII satisfaction and QoL improvement in patients on CSII the...
