Factors associated with secondary hyperparathyroidism in premenopausal women undergoing Roux-en-Y gastric bypass for the treatment of obesity.

Objective: To evaluate bone metabolism, bone density (BMD) and vertebral fractures in morbidly obese individuals.

Subjects And Methods: Case series of 29 premenopausal obese patients, 15 of whom had been submitted to bariatric surgery. Serum calcium, albumin, PTH and 25-hydroxy vitamin D (25OHD) were measured as well as bone densitometry of the lumbar spine and proximal femur, and lateral spine x-rays.

Bariatric surgery and bone metabolism: a systematic review.

Few studies have demonstrated the risk of metabolic bone disease and a reduction in bone mineral density (BMD) after bariatric surgery. A systematic review was conducted of case-control and cohort studies with the aim of evaluating the relationship between bariatric surgery and bone metabolism. The search was undertaken in MedLine, covering the period from January 1997 to August 2009, using the keywords: "bariatric surgery" AND "osteoporosis", "fracture", "bone diseases", "metabolic".

Morphometric and topographic study of coronary ostia.

Objective: To investigate the morphometric and topographic aspects of coronary ostia, correlating them with the aortic leaflets.

Methods: Fifty-one hearts with the great vessels attached were analyzed in this study. The ascending aorta was transversally sectioned 1 cm above the commissures of the aortic leaflets.
