Raloxifene is a selective estrogen receptor modulator which has shown to decrease bone resorption, increase bone density and reduce vertebral fracture rate in women with postmenopausal osteoporosis. Recent studies have shown a decrease on breast cancer incidence after raloxifene treatment. Although the mechanism is not clear, its mixed agonist and antagonist properties in different tissues could partially explain this effect.Objective: To evaluate the ef...

Progression of metabolic syndrome to diabetes is not easily predicted in patients with morbid obesity. We hypothesized that no insulin-resistance is more usual as we thought.Objective: Evaluate prevalence of no insulin-resistance status in patients with morbid obesity.Patients and method: The study was undertaken in 130 patients with a BMI of 53.93±6.67 kg/m2. The morbidly obese patients were divided into four group...

Association between anorexia nerviosa (AN) and low bone mass has been demonstrated. Bone loss associated with AN involve hormonal and nutritional impairments, though their exact contribution is not clearly established. We compare bone mass in AN patients with women of similar weight with no criteria for anorexia nervosa, and a third group of healthy, normal-weight, age-matched women. The study included 48 patients with AN (DSM-IV criteria), 22 healthy eumenorrheic women with l...

Adiponectin and leptin have been described as potential contributors to bone metabolism. The effect of anticatabolic drugs on these adipokines and their relationship with bone metabolism have not been clearly clarified.Aims: (1) Evaluate adiponectin and leptin levels in osteoporosic postmenopausal women and their relationship with BMD, bone turnover and osteoclastogenesis markers. (2) Analyze changes on adiponectin and leptin levels after treatment with ...

Low concentrations of vitamin D leads to secondary hiperparathyroidism, bone loss, and an increase of osteoporotic fractures in populations at risk. Adequate vitamin D and calcium intake is considered an essential component of postmenopausal osteoporosis management. Several epidemiological studies have assessed the prevalence of low serum vitamin D concentrations, indicating that vitamin D inadequacy (<30 ng/ml) is a problem world-wide.Aims: To evalu...

Introduction: 25-hydroxyvitamin D (25(OH)D3) deficiency has been associated with diabetes and obesity. However, the mechanisms underlying these relationships are not completely understood. Vitamin D receptor (VDR) is expressed in adipose tissue; it has been reported a higher expression in obese patients than in lean subjects, suggesting a differential vitamin D dynamics in adipose tissue according to the obesity degree. In addition, 1, 25-dihydroxyvitamin D3 (1,25(OH)2D3) is a...

Introduction: Percutaneous ethanol injection (PEI) or thyroid enolisation is a minimally invasive technique applicable to benign cystic thyroid nodules, not adhered to neighbouring structures, due to local compressive symptoms or aesthetic discomfort. Classically, the treatment of choice for these nodules has been simple aspiration, followed by surgery in refractory cases. Currently, PEI has emerged as an alternative to surgery due to its high efficacy, speed, safety, low rate...

Introduction: Treatment with Cinacalcet results in decreased uptake of radiopharmaceutical (because of decreased secretory activity of parathyroid glands as shown by previous studies in secondary hyperparathyroidism). This effect has not been studied in patients with primary hyperparathyroidism (PHPT).Objective: Evaluate clinical and MIBI scintigraphy uptake changes of adenomas in patients treated with Cinacalcet.Patients and metho...

Objectives: The primary objective was to determine if the use of Contour Next One (CNO) with Contour Diabetes app (APP) was associated with improved self-management using the Summary of Diabetes Self-Care Activities questionnaire (SDSCA). A secondary objective was to establish if CNO and APP together had impact on adherence to self-monitoring blood glucose (BG), indicated by frequency of BG readings and hypoglycemic events. Other secondary objectives were to observe a possible...
