Introduction: Due to the growing prevalence of obesity, more women are overweight in early pregnancy, leading to adverse neonatal and obstetric outcomes.Objective: To evaluate the influence of maternal prepregnancy body mass index (BMI) on blood glucose levels at diagnosis of gestational diabetes (GD), obstetric and neonatal outcomes.Methods: Retrospective observational study including women with GD and singleton pregnancy, with fo...

Introduction: Patients with germline mutations in one of the succinate dehydrogenase (SDH) genes are at substantially increased risk of developing paragangliomas (PGL) and pheochromocytomas (PCC). Mutations in SDHB are the most commonly found gene mutations in PC/PGL and are associated with younger ages at presentation, higher rates of metastases and poorer prognosis. Although familial PGL syndromes were initially thought to predispose only for PCC and PGL, other tumor types s...

The emergence of a new generation of long-acting insulin analogues (insulin degludec -ID- and insulin glargine 300 U/ml -IG300-) has increased treatment options in type 1 diabetes (T1D), demonstrating in clinical trials better metabolic control with lower hypoglycemia rates.Objectives: To assess characteristics of T1D patients who were given ID and IG300 in clinical practice and to evaluate their effect on metabolic control, weight, insulin dose and hypo...

Introduction: DNA methylation is one of the epigenetic mechanisms existing to regulate gene expression. It is believed that methylation of DNA is susceptible of change by environmental and nutritional factors. Thus, epigenetics provides a mechanism which may explain the etiology of some metabolic disorders and obesity.Aim: The aim of this study is to analyze the DNA methylation level of several lipoprotein lipase (LPL)-promoter-CpG island in human viscer...

Objectives: To study for the first time the differences in monocyte/macrophage infiltration, inflammation and adipogenesis in the subcutaneous and visceral adipose tissues of normal-weight subjects who differed in their degree of metabolic syndrome.Methods: The study included 92 normal-weight subjects who differed in their degree of metabolic syndrome. Anthropometric and biochemical parameters were measured. RNA from subcutaneous and visceral adipose tis...

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 ...

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...

Parathyroid carcinoma is a rare cause of primary hyperparathyroidism. Clinical suspicion is determined by the severity of hyperparathyroidism associated or not with palpable cervical tumor and local invasion when surgery.Case report: A 45-year-old woman without any previous history of kidney stones or fractures. Admitted to hospital because of high hypercalcemia (calcium 15.1 mg/dl), fatigue and generalized arthralgia. Physical examination revealed right...

The use of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG–PET) has increased the detection of thyroid incidentalomas (TI). These are associated with a risk of malignancy between 25 and 50%. Some studies show an association between SUVmax uptake and malignancy.The objective of this study was to determine the prevalence of malignancy on 18F-FDG–PET positive thyroid nodules and to evaluate the relatio...

Introduction: Obesity is defined as a chronic disease by AACE/ACE. Includes presence/severity of complications. VLCD diets induce relevant weight loss by improving these complications. PA is a bioelectric measure of the cell mass and it is marker a global prognostic factor of cellular functionalism.Methods: Case-control retrospective study of severe obesity in a weight loss program comparing intensive intervention (41 cases, VLCD 800 kcal/d, 1g protein/k...
