Several new serum markers for bone metabolism have recently become available and are being applied to clinical practice. Their clinical usefulness in predialysis patients with chronic renal failure (CRF), however, has not yet been determined. Serum levels of three bone formation markers-bone alkaline phosphatase (BAP), osteocalcin (OC), and N-terminal propeptide of type I collagen (PINP)-and three bone resorption markers-type I collagen cross-linked N-telopeptide (NTx), deoxypyridinoline (DPD), and pyridinoline (PYD)-were measured simultaneously in 85 predialysis CRF patients (serum creatinine 3.5 +/- 1.9 mg/dl, 61.0 +/- 10.9 years old, 54 males and 31 females, 36 diabetics and 49 nondiabetics) to examine the relationships between these markers and bone mineral density (BMD) of the distal radius, as measured by peripheral quantitative computed tomography (pQCT). ⋯ In multivariate regression analyses (adjusted by age, sex, presence of diabetes, glomerular filtration rate, intact parathyroid hormone, calcium, phosphate, and 1,25-dihydroxyvitamin D), OC and PINP were significantly associated with a decrease in BMD, but BAP was not. In conclusion, we demonstrated that in predialysis CRF patients, BMD of the distal radius, particularly of trabecular bone, is associated with serum OC and PINP levels. OC and PINP are suggested to be possible parameters for the clinical evaluation of the effect of bone metabolism on BMD.

Multicenter Study
Back pain, disability, and radiographic vertebral fracture in European women: a prospective study.
Vertebral fractures are associated with back pain and disability. There are, however, few prospective data looking at back pain and disability following identification of radiographic vertebral fracture. The aim of this analysis was to determine the impact of radiographically identified vertebral fracture on the subsequent occurrence of back pain and disability. ⋯ After adjustment for age, center, and frequency of back pain at baseline, compared with those without baseline vertebral fracture, those with a prevalent fracture were no more likely to report back pain at follow-up (OR = 1.2; 95% CI, 0.8 to 1.7). There was a small increased risk among those with a preexisting fracture who had sustained an incident fracture during follow-up (OR = 1.6; 95% CI, 0.6 to 4.1) though the confidence intervals embraced unity. In conclusion, although there was no significant increase in the level of back pain an average of 5 years following identification of radiographic vertebral fracture, women who suffered a further fracture during follow-up experienced substantial levels of disability with impairment in key physical functions of independent living.

We determined the current trends in the number and incidence of hospital-treated minimal-trauma rib fractures (low- to moderate-energy traumas typically caused by a fall from standing height or less) in Finnish elderly people by collecting from the National Hospital Discharge Register all patients 60 years of age or more who were admitted to hospitals in 1970-2001 for primary treatment of such fractures. The number and incidence (per 100,000 persons) of these fractures clearly increased from 268 (number) and 41 (incidence) in 1970 to 737 and 70 in 2001, while in younger patients (aged 20-49 years) the trend was decreasing, the corresponding numbers being 194 and 10 in 1970, and 153 and 7 in 2001. ⋯ In women aged 80 years and over, the age-specific incidence of fracture increased from 88 to 186, while in the other age groups only slight secular changes were found. If the above-described trends continue, the number of elderly Finns admitted to a hospital due to a rib fracture will more than double in next three decades.

A European Union (EU) directive on vitamins and minerals used as ingredients of food supplements with a nutritional or physiological effect (2002/46/EC) was introduced in 2003. Its implications for the use of oral supplements of calcium and vitamin D in the prevention and treatment of osteoporosis were discussed at a meeting organized with the help of the World Health Organization (WHO) Collaborating Center for Public Health Aspects of Rheumatic Diseases (Liège, Belgium) and the support of the WHO Collaborating Center for Osteoporosis Prevention (Geneva, Switzerland). The following issues were addressed: Is osteoporosis a physiological or a medical condition? What is the evidence for the efficacy of calcium and vitamin D in the management of postmenopausal osteoporosis? What are the risks of self-management by patients in osteoporosis? From their discussions, the panel concluded that: (1) osteoporosis is a disease that requires continuing medical attention to ensure optimal therapeutic benefits; (2) when given in appropriate doses, calcium and vitamin D have been shown to be pharmacologically active (particularly in patients with dietary deficiencies), safe, and effective for the prevention and treatment of osteoporotic fractures; (3) calcium and vitamin D are an essential, but not sufficient, component of an integrated management strategy for the prevention and treatment of osteoporosis in patients with dietary insufficiencies, although maximal benefit in terms of fracture prevention requires the addition of antiresorptive therapy; (4) calcium and vitamin D are a cost-effective medication in the prevention and treatment of osteoporosis; (5) it is apparent that awareness of the efficacy of calcium and vitamin D in osteoporosis is still low and further work needs to be done to increase awareness among physicians, patients, and women at risk; and (6) in order that calcium and vitamin D continues to be manufactured to Good Manufacturing Practice standards and physicians and other health care professionals continue to provide guidance for the optimal use of these agents, they should continue to be classified as medicinal products.

The aim of this study was to describe the consequences of hip fracture with respect to changes in residential needs and the ability to perform activities of daily life. Patients 50 years and older admitted to the two largest hospitals of Oslo with a hip fracture during the period May 1996 through April 1997 were identified. In November 1997 a questionnaire on residential needs, activities of daily life, hip pain and health status was sent to the patients still alive (n = 767). ⋯ The probability of these events increased with increasing age. The probability of reporting inferior health status and for having hip pain that affected sleep after the fracture was unrelated to age. Many patients sustaining a hip fracture, and in particular the oldest patients, have reduced ability to perform activities of daily life.
