Introduction: Hereditary Medullary Thyroid Cancer (MTC) accounts for 20–30% of cases and has some clinically relevant peculiarities.Material and methods: Retrospective, unicentric cohort study that included all genotyped patients with MTC (n=48) diagnosed at Hospital Clínico San Carlos (Madrid) between 1984–2013; 42% were germline mutation carriers (45% moderate risk (category MOD), 45% high risk (category H), 10% highest risk (ca...

Introduction: New techniques such as etapification ecotomography (EE) have led to less invasive surgeries in Differentiated Thyroid Cancer (DTC). The trend in recent years has been to a reduction in the doses of radioiodine administered. Our hospital in 2013 incorporated these features to protocolize the administration of radioiodine depending on the characteristics of the tumour and the initial thyroglobulin levels, which may have had an impact in the response to treatment (R...

Introduction: The prediction of the risk of recurrence in differentiated thyroid cancer (dtc) in chile is different from ata. The use of the stimulated thyroglobulin (tg) post-surgery in the prediction of the risk is controversial. We present a cohort applying a new local protocol that includes the tg for supporting the discrimination of the patients for offer low doses or radio iodine.Objective: Asses if the local risk classification (lc) allow us to di...

Adrenocortical carcinoma (ACC) is a rare malignancy, but accounts for up to 11% of adrenal masses investigated in referral centres. Diagnosis remains a challenge. Up to two thirds are biochemically inactive, resulting from de facto enzyme deficiencies in the steroid hormone biosynthetic pathways, as shown by urine steroid profiling by gas chromatography-mass spectrometry. Increased metabolites of pathway intermediates in ACC discriminate it from benign adrenal lesions...

Introduction: Decreased bone formation has been proposed as a mechanism involved in the higher risk of fractures in diabetic patients. Some clinical studies have found that sclerostin (SCL, a negative regulator of bone formation) is increased in diabetic patients. However, there is no information about the relationship between SCL and new onset diabetes after transplantation (NODAT). The aim of our study is to evaluate serum SCL levels in a cohort of patients with liver transp...

Pituitary ACTH-secreting tumour presents with variety of clinical features: normal cortisol secretion and ACTH-immunopositive staining and mild hypercortisolism without typical features of Cushing’s disease. We present a 53-year-old male with history of hypertension. First visit (2005): visual loss, bitemporal hemianopsia in campimetry and in MRI pituitary adenoma (2.5 cm) invading cavernous sinus and suprasellar cister. Hormonal study supported panhypopituitarism. After ...

Aims: To study if BRAF V600E mutation in thyroid fine needle aspiration (FNA) is associated with specific ultrasound (US) characteristics.Patients and methods: From 2010 to 2014 we reviewed patients with thyroid nodules with the following inclusion criteria: US guided FNA of the nodule and molecular testing for BRAF V600E on the FNA. BRAF mutation was detected using fluorescence melting curve. An expert on US, blinded to the BRAF status reviewed US exami...

Introduction: Oncocytomas are tumours composed by oncocytes, cells with granular and eosinophilic cytoplasm filled with mitochondria. It is a neoplasm that can arise in several organs (more commonly described in the kidney, salivary gland and thyroid). Oncocytoma arising in the adrenal gland is a rare finding. Most of them are benign and non-functioning and are detected incidentally. However, functional adrenal oncocytomas presenting as Cushing’s syndrome and phaeochromoc...

Introduction: Cushing’s syndrome (CS) due to macronodular adrenal hyperplasia ACTH-independent (MAHAI) is rare. Regulation of cortisol secretion by G-protein-coupled receptors (GPCRs) aberrantly expressed is frequently found in MAHAI. Various aberrant receptors have been reported, mostly: GIP, vasopressin, beta-adrenergic, LH/hCG and serotonin.Case report: 61 years old woman. Medical history: type 2 diabetes, hypertension, obesity, dyslipidaemia and...

The 2013 guideline (NHLBI ATP IV) on the treatment of blood cholesterol in adults was recently published. It focuses on identification of 4 Statin Benefit Groups (4SBG), in which the potential for Atherosclerotic Cardiovascular Disease (ASCVD) risk reduction benefit clearly exceeds the potential for adverse effects.Objective: To estimate the prevalence of 4SBG among Venezuelan women and to determine its association with hypertension, BMI, waist circumfer...
