In recent years guidelines for the testing and treatment of osteoporotic patients have been published by recognised organisations, including the World Health Organisation (WHO), the National Osteoporosis Foundation (NOF) and the International Osteoporosis Foundation (IOF). Dual Energy X-ray Absorptiometry (DXA) has been considered the technique of choice(More)
OBJECTIVE To investigate the effect of acute resistance exercise on adipose tissue triacylglycerol lipase activity (TGLA) in lean and obese men. RESEARCH DESIGN AND METHODS Nine lean and eight obese men performed 30 min of circuit resistance exercise. Adipose tissue and blood were sampled during exercise for TGLA, metabolite, and hormone determinations.(More)
OBJECTIVE To evaluate the time course of leptin, adiponectin, and resting energy expenditure (REE) responses in overweight elderly males after acute resistance exercise protocols of various intensity configurations. RESEARCH DESIGN AND METHODS Forty inactive men (65-82 years) were randomly assigned to one of four groups (n = 10/group): control,(More)
X-linked hypophosphatemic rickets (XLH) is a dominant disorder characterized by hypophosphatemia due to impaired renal tubular reabsorption of inorganic phosphate. Cardinal manifestations include defective calcification of cartilage and bone, growth retardation and resistance to phosphorus and vitamin D therapy. Although secondary hyperparathyroidism (HPT)(More)
Strontium ranelate (SR) is a novel anti-osteoporotic agent approved for the treatment of postmenopausal osteoporosis. SR appears to reduce bone resorption by decreasing osteoclast differentiation and activity, and to stimulate bone formation by increasing replication of pre-osteoblast cells, leading to increased matrix synthesis. The effect of SR on bone(More)
OBJECTIVES To clarify potential differences between denosumab (DNS) and bisphosphonates (BIS) in terms of bone density and bone metabolism, in a sample of postmenopausal women. METHODS A total of 113 postmenopausal women aged 53-66 years were treated with either DNS or BIS for 12 months. Bone densitometry and laboratory tests were compared between(More)
There are numerous studies presenting the beneficial effect of bisphosphonates (BPs) on bone disease of patients suffering from beta-thalassemia major (TM). Although BPs have been widely used, adverse events have been described including atypical femoral fractures (AFF). In the present case, a male adult patient suffering from TM sustained an AFF fulfilling(More)
Case A 22-year old female presented in 2008 at the outpatients clinic of our department for evaluation of an extended pelvic osteoly-sis, being diagnosed accidentally after a fall fifteen days before administration. The patient reported inability to weight bearing and intense pain at her left hip. On clinical examination, edema of the proximal femur was(More)
UNLABELLED Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome caused primarily by benign mesenchymal tumors. These tumors typically follow a benign clinical course and local recurrence occurs in <5% of cases. We investigated a 49-year-old man with a recurrent mesenchymal phosphaturic tumor showing no signs of malignancy. The patient suffered(More)
