PURPOSE To evaluate whether the operating time correlates with the survival and outcome in patients who underwent intramedullary nailing for metastatic femoral fractures. METHODS Records of 10 men and 11 women aged 43 to 86 (mean, 66) years who underwent intramedullary nailing (4 bilaterally) for metastatic femoral fractures between 1999 and 2003 were(More)
The effect of sodium intake on the excretion of calcium, hydroxyproline (OHP) and serum parathyroid hormone (PTH) was examined. When seven healthy males increased their sodium intake by 200 mmol/day, excretion of calcium increased by 1.70 mmol/day and that of OHP by 27%. Serum PTH, however, did not increase significantly. In a cross-sectional study of 334(More)
BACKGROUND Quality of care measured by adverse events cannot address errors of process that have no adverse outcomes. The aim of this study was to determine whether process could be used to assess quality of care and whether process analysis could be used to assess interventions designed to improve quality. METHODS A single-centre prospective cohort study(More)

We describe a case of a patient receiving warfarin who presented with a superior pubic ramus fracture after a trivial fall at home. She developed a massive retroperitoneal haematoma as a result of vascular injury and subsequently died. This case emphasises the importance of admitting and observing patients with pubic rami fractures who are receiving(More)
An evaluation of the capability of organic chemicals to mineralize is an important factor to consider when assessing their fate in the environment. Microbial degradation can convert a toxic chemical into an innocuous one, and vice versa, or alter the toxicity of a chemical. Moreover, primary biodegradation can convert chemicals into stable products that can(More)
Plasma concentrations of calcium-phosphate, alkaline phosphatase, 25-hydroxyvitamin D (25(OH)D) and albumin, and fasting urinary sodium/creatinine (Na/Cr), calcium/creatinine (Ca/Cr) and hydroxyproline/creatinine (HPr/Cr) were measured in a survey of 208 Chinese elderly subjects living in chronic care institutions, and compared with values from free-living(More)
