IntroductionPituitary apoplexy (PA) consists of acute infarction/hemorrhage of the gland, involving mostly a previously unrecognized adenoma. One of its most documented precipitating factors is anticoagulation in the context of acute coronary syndrome treatment. To our knowledge only one report described a PA secondary to anticoagulation for pulmonary thromboembolism.Case reportA 75-year-old men with known hy...

Introduction and objectives: The treatment with monoclonal antibodies that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) is a new group of drugs that allows us to reach the therapeutic targets of low density cholesterol (LDL-c) in patients intolerant to statins or those who despite treatment with maximum doses of them do not obtain a proper lipid control.Material and methods: We performed a descriptive observational study. We include all ...

Epidemiological studies have shown that caffeine increases plasma SHBG levels and also reduce the risk of type 2 diabetes. There are no reports describing any molecular mechanism by which caffeine regulates hepatic SHBG production. The aim of the present study was to explore whether caffeine regulates SHBG production and to determine the associated molecular mechanisms. For this purpose, in vitro and in vivo studies were performed using human HepG2 cells and ...

Background: Brown adipose tissue (BAT) plays a pivotal role in the regulation of energy homeostasis and thermogenesis. This tissue responds to insulin, favoring the expression of uncoupling protein-1 (UCP-1), that in turn is inhibited by insulin-desensitizing cytokines. Leptin may abolish some of the effects of fasting on these parameters through its cross-talk with insulin-related signaling targets.Objectives: We hypothesized that leptin infusion preven...

Introduction: Both insulin resistance and oxidative stress are implicated in the pathophysiology of various diseases such as type 2 diabetes mellitus, atherosclerosis or liver disease. Furthermore, the uncoupling protein-1 (UCP1) is involved in induced thermogenesis, related to the pathogenesis of obesity and diabetes. The aim of this study was to assess the impact of aerobic exercise on the inflammatory profile in patients with chronic hepatitis C.Metho...

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...

Background and aims: Periodontal disease (PD) is a chronic inflammatory condition where the key feature is the alveolar bone loss. Diabetes mellitus is a major risk factor in the occurrence of PD and vitamin D has been found to play a role in the development of diseases such as PD for its immunomoduratory and anti-inflammatory effects. The purpose of this study was to evaluate the relationship between PD and vitamin D levels in type 1 diabetic patients.S...

Introduction: The new guidelines for the management of hypothyroidism (HP) during pregnancy recommend a tighter treatment with levothyroxine (Lt4) to reach TSH values similar to those of pregnant women without thyroid dysfunction (TSH <2.5 mU/l in the 1st trimester-T- and TSH <3mu/l in the 2nd and 3rd T).Objectives: To assess the degree of control of HP in women followed during pregnancy according to the current criteria and the possible associat...

Objective: Addison’s disease (AD) is a rare and complex endocrine disorder. Genetic susceptibility loci known so far are predominantly shared with other, more frequent autoimmune endocrinopathies. We therefore investigated polymorphisms of the CTLA4-region, the vitamin D system (vitamin D receptor VDR, CYP24 and CYP27B1 gene) as well as cytokine CXCL10 gene for their association in AD.Methods: Patients with AD (n=203) and healthy controls (<i...

Familial combined pituitary hormone deficiency can be due to a PROP 1 gene mutation. PROP1 is essential to pituitary morphogenesis. Mutations with inactivation of this gene results in deficiency of GH, PRL, TSH, LH, FSH and in some cases, ACTH.The authors describe an affected family, two sibs, with panhyopituitarism: a 10 years old female, and a 15 years old male, who presented with growth and pubertary development delay. Both children lacked GH, TSH, PR...
