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 ...

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 ...

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...

Introduction: Maternal obesity is associated with an increased risk of gestational diabetes, large for gestational age (LGA) newborns, preterm delivery, congenital malformations, and fetal death. On the other hand, bariatric surgery before pregnancy is associated with a reduction of obesity-associated complications, but also with an increased risk of small for gestational age (SGA) newborns, fetal growth restriction and micronutrient deficiencies during pregnancy.<p class=...

Introduction: Parathyroid carcinoma (PC) is an extremely rare malignancy. A complete surgical excision is often difficult, and persistent/recurrent disease occurs in up to 65% of cases. Progression often leads to symptomatic hypercalcemia, the major contributor to poor quality of life and mortality. Treatment options beyond surgical resection are limited. Denosumab is an approved therapy for refractory hypercalcemia of malignancy, and its use in unresectable PC has been descri...

Introduction: Propylthiouracil is a drug used in the treatment of hyperthyroidism and autoimmunity phenomena have been described as a side effect of its use. Despite anti-neutrophil cytoplasmic antibodies (anca) positivity is frequent in patients treated with propylthiouracil, the occurrence of clinically evident vasculitis is rare.Case report: A 65-year-old woman, diagnosed with hyperthyroidism 2 years ago and treated with propylthiouracil (50+...

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...

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: Pituicytoma is a low-grade glioma of the suprasellar and sellar regions that is rarely described (about 60 cases described in the literature). The clinical, laboratory and neuroradiological findings are not pathognomonic, and therefore definitive diagnosis is only possible after surgery and histopathological study. Total resection is the treatment of choice, since subtotal removal can often lead to recurrence or progression.Case report: We ...
