Bilateral cervical exploration has been the gold standard in parathyroid surgery. Nowadays, the preoperative localization procedures have facilitated the minimally invasive surgery. This study aims to analyze the influence of thyroid disease in Tc99m-sestamibi scintigraphy (MIBI) results.A series of 154 patients with PHP who underwent parathyroidectomy was reviewed. Patients were divided into two groups: group 1 (G1, 58 patients) with thyroid diseases, a...

Background: Primary aldosteronism is a common cause of arterial hypertension, but its underlying molecular mechanisms are unknown. K+ is a key regulator of aldosterone secretion: it interacts with physiological secretagogues of aldosterone as angiotensin II (Ang II) end endothelin-1. In vivo genetic manipulation of a widely distributed class of channels, which generate background or ‘leak’ potassium (K+) currents, the twik-related acid-se...

Objective: To identify MetS and non-MetS in subjects with adult-onset GHD before start of GH replacement and to compare prevalence of cardiovascular risk factors.Subjects and methods: MetS was defined (IDF criteria) by the obligatory presence of increased waist circumference (WC) and presence of at least two of following components: hypertension, decreased HDL-cholesterol, increased triglycerides, diabetes mellitus. The complementary group was defined as...

Background: Oncocytomas are predominantly benign tumors that are well described in the kidney, thyroid and salivary glands. They have also been reported in more rare sites including the pituitary and parathyroid glands, respiratory tract and choroid plexus. The occurrence of these tumors in the adrenal gland, however, represents an extremely exceptional finding.Case presentation: We report the case of a 34 year-old male patient who presented with a right...

The change of aminoacid Arginine (CGG) to Glutamine (CAG) at position 171 (R171Q) in the MEN1 gene has been occasionally reported in MEN1 carriers, but also in 1.4 to 5% subjects among the general population, therefore it is still unclear whether it might represent a polymorphism and/or it has a role in tumourigenesis. The aim of our study was to evaluate the presence of the R171Q polymorphism in patients with MEN1-related states presenting for MEN1 genetic screening. F...

Glucose metabolism alterations are frequently observed in acromegalic patients. Somatostatin analogues (SSTA) are the most widely used drugs to treat acromegaly, since they inhibit GH and IGF-1 levels, reduce pituitary mass, but can affect glucose metabolism. Aim of our study was to evaluate glucose metabolism alterations in acromegalic patients cured after surgery and in patients with active disease during treatment with SSTA. We studied 10 patients (group A, 5F, 55.66±1...

Objective: Androgen may be detrimental for vascular health in women. Sensitivity to androgen is influenced by the CAG repeat length of the androgen receptor (AR) gene. We investigated possible associations between the CAG repeat polymorphism with the severity of CAD in women undergoing coronary angiography.Methods: We examined 131 postmenopausal women (45–88 years). CAD severity was assessed by the number of coronary vessels with >50% stenosis. ...

Ghrelin is a pleiotropic hormone characterized mainly by its strong orexigenic action and its role as GH secretagogue.Age-related level variation of this hormone has been previously shown in different studies centred in mARN expression and in its plasma levels; however there is no data about its secretion directly from the stomach although this is the main ghrelin producing organ.Objectives: To determine the levels of ghrelin in th...

Background: Although primary hyperparathyroidism (PHPT) has been associated with diabetes mellitus (DM), the etiological link is not clear and the effect of parathyroidectomy is controversial.The aim of this observational study was to investigate the metabolic link between calciotropic hormones and glucose metabolism in PHPT patients before and after parathyroidectomy.Methods: Twenty-four consecutive patients with PHPT (Group-A) without DM were included ...

Objective: To evaluate the efficacy of dapagliflozin for glycemic control and progression of weight loss after stabilization with liraglutide 1.8 mg.Patients and methods: Descriptive study: patients with tipo 2 diabetes (DM-2) in treatment with metformin and liraglutide 1.8 mg, optimal metabolic control, which after stabilization in weight loss, liraglutide is suspended and dapagliflozin is added. Variables analyzed baseline and at 6 months after treatme...
