There is concern about the effects of long-term bisphosphonate use. A ‘treatment holiday’ is now considered after 5 years but there is no evidence as to the best way in which to monitor this.Aim: To look at the effect that a ‘treatment holiday’ has on the bone turnover marker, amino-terminal propeptide (P1NP) and bone mineral density (BMD).Methods: A retrospective case note review of 55 patients currently underg...

Idiopathic infantile hypercalcemia (IIH) (OMIM 143880) is characterised by severe hypercalcemia, failure to thrive, vomiting, dehydration and nephrocalcinosis. Laboratory evaluation of infants affected with this condition reveals hypercalcemia, suppressed parathyroid hormone and hypercalciuria. Recently loss of function mutations in CYP24A1 gene have been found to cause IIH (New England Journal of Medicine 2011 365 410–21). Short-term treatment for th...

Considerable dichotomy exists in the phenotype of adults with severe GHD of childhood (CO-GHD) and adult-onset (AO-GHD). Those with CO-GHD show immaturity. Adults with partial GHD (GH insufficiency (GHI), peak GH 3.1–7.0 μg/l) show a similar, but milder phenotype to adults with severe GHD. Whether a similar dichotomy relating to timing of onset is observed in CO-GHI and AO-GHI adults is not known.We studied 24 adults with GHI (CO-GHI n=1...

Introduction: Testosterone (T) improves muscle strength in hypogondal patients. It is unclear if testosterone has similar effects in frail elderly men with low T. We conducted a randomised double-blind placebo-controlled parallel group study to determine the effects of T on muscle mass and strength, physical function and quality of life in frail elderly men from the general population.Methods: Two hundred and sixty-two prefrail and frail elderly men (cri...

Ageing is associated with sarcopenia, osteoporosis and an increased risk of falling, which together contribute to increased fracture risk. There are few data describing the associations between functional measures of muscle and bone during ageing. Therefore, the aim of this study was to examine in ageing men associations between measures of lower-limb muscle strength and age and then to investigate the relationships with tibial bone outcomes.Men (n</...
