Introduction: Bariatric surgery has important metabolic complications such as bone mass loss.Goal: To assess bone mineral density (BMD) after Roux-en-Y gastric by-pass (RYGB) in patients under standard calcium and vitamin D supplementation.Method: In patients with morbid obesity submitted to RYGB, we measured BMD with a dual X-ray densitometer. Using World Health Organization (WHO) criteria’s, values were compared with young c...

Introduction: Thyroid nodules are very common in the general population (20–75% ultrasound). There are clinical management criteria established by international societies and standardized cytological diagnostic criteria (Bethesda). However, there is still uncertainty in the management of category 3 (follicular lesion of undetermined significance). Objectives: To evaluate the clinical attitude to the cytological diagnosis of Bethesda category 3 (B3) in thyroid fine-needle ...

Objectives: Pregnant women who are overweight or obese have an increased risk of complications during pregnancy, as do pregnant women with type 1 diabetes mellitus (DM1). The objective of this study is to describe the prevalence of overweight/obesity in pregnant women with DM1, and associated complications.Patients and methods: Retrospective descriptive study of pregnant women with DM1 (2004–2014). Variables analyzed: age, initial body mass index (B...

Background: Acromegaly is the consequence of excessive growth hormone (GH) secretion, usually produced by a pituitary adenoma. In the last years, statins have been implicated in the response to treatment of patients with acromegaly. Although this fact is not very clear.Objective: To analyze whether pretreatment with statins modifies the adenoma molecular phenotype of the acromegalic patients and how this changes could help to influence the response to tr...

Background: In a previous publication we identified the major predictive factors of levothyroxine (LT4) requirement and proposed an efficient nomogram to calculate LT4 substitutive starting dose after total thyroidectomy for benign disease. The aim of this study was to assess whether the LT4 requirement differs between the tablet and the soft gel capsules formulations.Methods: One hundred and three consecutive patients su...

Thyroglobulin (Tg) is a highly sensitive tumor marker of differentiated thyroid cancer (DTC). To optimize the sensitivity, guidelines recommend Tg measurement after stimulation with recombinant TSH (rh-TSH) 6–12 months after radio remnant ablation (RRA). Based on recent evidence in Literature, it is possible to avoid the measurement of Tg after stimulation with rh-TSH (S-Tg) in presence of undetectable values of basal Tg (B-Tg) if high functional sensitivity (0.1 ng/ml) m...

Objective: Obesity and overweight persist in patients with Cushing’s disease (CD) in remission, its persistence seems to be related to the duration of the disease. The aim of this study was to describe the persistence of overweight/obesity in patients with CD in remission and their relation to the duration of the disease.Patients and methods: Descriptive study of patients with CD (1995-2015). Variables analyzed: age, sex, body mass index (BMI), time...

Introduction: Differentiated thyroid cancer (DTC) is the most frequent endocrine cancer. After surgery followed, if any, by 131I radio remnant ablation (RRA), follow-up monitoring consists of neck ultrasonography (US) and measurements of thyroglobulin (Tg) levels and anti-Tg antibodies (Ac-Tg) both on levothyroxine (L-T4) therapy and after recombinant TSH (rTSH). The aim of our study is to define a cut-off of Tg before RRA (RRA-Tg) during <...

Objective: The aim of this study was to assess the utility of arterial calcium stimulation with hepatic venous sampling (ASVS) in the localization of tumors in patients with endogenous hyperinsulinism not detected with other methods.Patients and methods: We performed a retrospective study of 30 patients admitted to our hospital for hypoglycemia who underwent ASVS because the source of hyperinsulinism was not clearly identified by other imaging techniques...

Subclinical CS, mild hypercortisolism without overt clinical manifestations, is the most frequent (5–8%) hormonal abnormality detected in patients with secreting adrenal incidentalomas.Unclear clinical features and mild hypercortisolism make the diagnosis problematic, although laboratory criteria have recently been reviewed. In these cases, scintiscan is a central tool to define the adrenal functional activity.A 60-year-old ma...
