Control of CRFs in T2DM patients results in a clinically important reduction in the risk of death and complications related to diabetes.Objective: To assess the degree of control of modifiable CRFs in treated T2DM patients, stratified by diabetes therapy.Materials and methods: Cross-sectional study in 574 T2DM patients who attended our clinic for a routine follow-up. Fasting plasma glucose (FPG), HbA1C, HDL-Cholesterol (HDL-Ch), LD...

Retrospective study of patients with metastatic/progressive pheochromocytoma (PCC) and paraganglioma (PGL) treated with (131) I MIBG in our hospital during 2015–2018 period.Methods: There are no established criteria for establishing PCC/PGL as malignant apart from de presence of metastases at diagnosis. Radionuclide therapy (131) I-metaiodobenzylguanidine (MIBG) is frequently used in this patients when surgery is not possible. Indication of MIBG tre...

Introduction: Vitamin D deficiency is very common in the population, including pregnant women. There are few studies in Spain to explain their causes, so we started one in the city of Burgos, Spain (latitude 42.2° N) in April 2009 to study vitamin D status, factors that can influence and their relationship with gestational diabetes. We present preliminary data from the study on vitamin D levels.Aims: Study in pregnancy: i) vitamin levels, and ii) it...

Introduction: An increased risk of thyroid disease (TD) has been described in patients with type 1 diabetes (DM1) with respect to the general population. The objective is to establish the incidence and characterize the differences in patients who develop TD in relation to the debut of DM1 (previous, concurrent or a posteriori).Materials and methods: Retrospective study of 1126 patients followed up in Endocrinology consultations in Navarra. Three types of...

Aim: Differential diagnosis (DD) of thyrotoxicosis is critical as the treatment of the three main causes of this condition (Graves’ disease [GD], Toxic Multinodular Goitre [TMG], and Thyroiditis [TS]) differs substantially. Recently published diagnostic algorithms investigating hyperthyroidism embrace the presence of thyrotropin receptor (TSH-R) antibodies (TRab) as the first and most cruicial diagnostic step. Although TRab measurement has important limitations (some can ...

About 10–15% of prolactinomas (P) are resistant to Dopamine agonists (DA). We analyzed retrospectively ten resistant prolactinomas (RP) treated at our center between 1995 and 2014, to identify useful variables to predict DA resistance and its different patterns (biochemical resistance (BR), morphological resistance (MR) or both). BR is defined as the failure to normalize prolactin (PRL) levels with ≥ 2 mg/week of cabergoline (C) for at least 3 months. MR is consider...

Objectives: We studied whether the postoperative serum thyroglobulin (TG) basal levels before treatment with I131 (baseline TG) could be related with the response to treatment. We consider the excellent response as the absence of clinical, biochemical disease (undetectable TG and anti-thyroglobulin antibodies AcTG negative) and/or structural disease.Material and Methods: This is an observational study that includes 100 patients with differentiated thyroi...

Morbid obesity (MO) is often complicated by obstructive sleep apnoea (OSA), which in some cases is evaluated by pulsioximetry. This cross-sectional study was designed to investigate the prevalence of discordance between desaturation index (DI) and apnoea–hypopnoea index (AHI) and its effects on insulin resistance and secretion in MO patients candidate to bariatric surgery (n=496) in whom a full polysomnographic study was carried out. We identified 163 (33%) out o...

Obesity is a disease very prevalent and often associated with morbidities and cardiovascular risk factors. We explore the relationship between the presence of obesity with cardiovascular risk factors more frequent and the presence of cardiovascular disease (CVD) after (ischemic heart disease, cerebrovascular disease, peripheral artery).Material and methods: A sample of 1491 individuals of both sexes, over 14 years, elected by random sampling three of the...

Aim: A key diagnostic step to determine the cause of hyperthyroidism is the measurement of circulating thyroid-stimulating immunoglobulin (TSI). High levels are associated with Graves’ disease (GD). A thyroid scintigraphy (TRS) is recommended when TSI is absent or its measurement unavailable, as TRS is capable of differentiating between GD (diffuse uptake) and toxic goitre (TG) (patchy uptake). Nevertheless, and while rarely necessary, histopathology remain the best metho...
