The demonstration of postnatal stem cells in the adenopituitary (PSC) a few years ago has made us to redraw many of the cell biology concepts that we previously had for this gland. PSC organize in a three-dimensional structure, the niche, where they combine with other populations. How many populations cohabit in the niche, and which markers should we use to define cells associated to PSC we still do know not. However, we have advanced in the definition of a PSC as a cell co-ex...

Calcium-sensing receptor gene (CASR) loss-of-function mutations lead to familial hypocalciuric hypercalcaemia (FHH), neonatal severe hyperparathyroidism, and primary hyperparathyroidism. FFH is characterized by mild hypercalcaemia, hypocalciuria, calcium clearance/creatinine clearance (CaCl/CrCl) <0.01, normal or high PTH level. Nevertheless the phenotype may vary (Thakker 2012). The aim of this work was to compare the phenotypes of patients bearing or not a pathogenic <em...

Introduction: Fine-needle aspiration biopsy (FNAB) of the thyroid gland is an accurate diagnostic test used routinely in the initial evaluation of nodular thyroid disease. A sizeable subset of patients are found to be taking antithrombotic and/or anticoagulant (AT/AC) medications. This creates a dilemma for the endocrinologist, who must weigh the risk of withholding these medications (and the associated potential benefit of diagnosis) against the perceived increased risk of ia...

Introduction: Functional islet β-cell tumours represent 1–2% of all pancreatic neoplasms. Diagnosing this type of tumour is often challenging because they present with unspecific clinical features overlapping more common syndromes. Diagnosis involves expensive testing, so, establishing whipple’s triad and excluding causes of exogenous hyperinsulinaemia is crucial before initiating investigation.Objective: To report a rare case of a proinsu...

Introduction: The diagnosis of non-HIV lipodystrophies is challenging, especially since borderline forms with type 2 diabetes have been described (Strickland Diabetes Care 2013).Objective: To identify the most specific anthropometric and biological parameters enabling to differentiate lipodystrophic from obese and control subjects.Methods: This prospective study (clin.gov 2009-AO-1169-48) included 94 patients divided in 3 groups ad...

Objective: To evaluate the response to treatment with insulin infusion pumps by the evolution of HbA1c over 8 years of experience.Methods: Observational retrospective study. We evaluated the response to treatment in 122 patients with type 1 diabetes recruited between 2004 and 2012 in our area.Results: Between 2004 and 2012, 122 pumps have been implemented (average of 17.4 pumps/year). The number decreased to only four in 2012. Pres...

Introduction: In singleton pregnancies, gestational diabetes mellitus (GDM) results in an increased risk for maternal and neonatal complications. In twin pregnancies, however, the effect of GDM on maternal and neonatal complications appears to be different in comparison to singletons. The few studies that investigated the consequences of GDM in twin pregnancies are small and present conficting evidence, with some finding no difference in perinatal outcomes between GDM and non-...

Objective: To analyze the impact of a specialized management on cardiovascular risk at the onset of type 2 diabetes mellitus.Material and method: Were analyzed 171 patients who visited our diabetes day hospital (DDH) during 2010–2011, studying the following variables: sex, age, BMI, smoking habit, arterial hypertension (de novo/previously known), antihypertensive therapy, dislypidemia (de novo/previously known), hypolipidemic thera...

Objective: To analyze the demographic and clinical characteristics of the patients treated at the onset of type two diabetes mellitus in our DDH.Material and method: During 2010–2011 were analyzed 171 patients treated in our DDH, studying the following variables: sex, age, BMI, waist circumference, family diabetes history, microvascular and macrovascular long-term complications, smoking habit, rate of associated hypertension (de novo/ previ...

Aggressive adreno-cortical carcinoma (ACC) is a rare, aggressive malignancy, with poorly understood molecular pathogenesis. As a result, therapeutic options are currently limited, surgery being currently the lone curative modality. Most cases of ACC are sporadic, although some familial cancer syndromes (Li–Fraumeni, Beckwith–Wiedemann, MEN1, Carney complex, congenital adrenal hyperplasia, etc.) are associated with an increased incidence of ACC. The genes involved in ...
