Vitamin D insufficiency is a reemerging and common health problem for skeletal system. Pharmacological application of glucocorticoid inhibits intestinal calcium absorption and stimulates tubular calcium excretion, thus induces severely negative calcium balance. We report a patient presenting symptomatic hypocalcemia following high dose glucocorticoid administration. After a pulse-therapy with methylprednisolone,...
Coating of stainless steel screws with bisphosphonate in a fibrinogen matrix leads to an enhancement of the pullout strength 2 weeks after insertion in rat tibiae. This effect then increases over time until at least 8 weeks. The pullout force reflects the mechanical properties of the bone within the threads, which acts as a screw nut. The aim of the present study was to find descriptive and morphometric...
Bisphosphonates (BPs) target bone due to their high affinity for calcium ions. During osteoclastic resorption, these drugs are released from the acidified bone surface and taken up by osteoclasts, where they act by inhibiting the prenylation of small GTPases essential for osteoclast function. However, it remains unclear exactly how osteoclasts internalise BPs from bone and whether other cells in the...
Consensus guidelines for the treatment of Paget's disease of bone have been published, but it is not known how closely these reflect clinical practice. We conducted a multi-centre, stratified, retrospective review of case notes of 531 subjects treated for Paget's disease of bone between 2000 and 2005 in 29 Australian centres. The subjects received 1072 courses of bisphosphonate treatment (pamidronate...
