Introduction: Medullary thyroid cancer (MTC) TNM classification categorizes lymph nodes (LN) according to their location, but does not consider number and size of LN.Objective: To analyze the relationship between number and size of LN in MCT persistent disease (PD).Material and methods: Retrospective study of patients with MTC followed up in a regional hospital from 1985 to 2015. The main variables (expressed as qualitative in freq...

Introduction: Primary hyperparathyroidism results in increased bone resorption. The presence of osteoporosis is at present an established surgery criteria.Objective: The aim of this study was to evaluate the changes in bone mineral density (BMD) after surgery in patients with primary hyperparathyroidism.Material and methods: Retrospective study of 58 patients with primary hyperparathyroidism treated by parathyroidectomy from 2004 t...

Evaluation of bone quality represents a challenge since the analysis by bone mineral density (BMD), provides useful but incomplete information. New tools are arising, and amog them, TBS is emerging as a new surrogate marker of bone texture and microarchitecture which may be useful to potentially evaluate the risk of bone fracture and can be obtained from already existing BMD scans. Retrospective study of 23 patients with PHH. Clinical, analytical and BMD data were collected fo...

In liver, melatonin (Mel) and glucocorticoids (GC) influence the systemic energy homeostasis. Animals without pineal gland present impairment in glycemic control, as in type-2 diabetes. In turn, Mel reduces the GC levels, particularly in nocturnal animals. We aimed to evaluate the influence of Mel, as well as GC receptor blockade by RU486 treatment on hepatic and pancreatic energy metabolism. Male Wistar rats were subjected to surgical removal of pineal and, 25 days after the ...

Background: Pregnancy alters the natural history of autoimmune thyroid disorders. The incidence rate of positive thyroid antibodies (T-abs +) in asymptomatic women during pregnancy has been reported to be between 6 and 19.6%.Aim: To determine the prevalence of thyroid antibodies (T-abs) in Gestational Diabetes Mellitus (GDM).Subjects & Method: In 408 women, at the time of diagnose of GDM, TSH, free thyroxine, free tri-iodothyro...

Introduction: One of the main difficulties in the study of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is their wide heterogeneity and variable outcome. Several potential influencing factors on patient survival have been recently identified. These factors could help predict patients’ prognosis.Objectives: Analysis of long-term survival of our GEP-NETs cohort according to the presence of metastatic disease, tumor grade, age, sex, tumor fu...

Introduction: Angiopoietins (ANG) -1 and 2, their receptor TIE2, and the vascular endothelial growth factor (VEGF) are involved in the process of angiogenesis. However, their role in the pathogenesis and development of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) is not completely understood. In a previous study of 42 patients with GEP-NET, we observed an elevation of these serum markers, especially in those with metastatic disease. The objective of this study was ...
