Prevalent vertebral fractures and minor vertebral deformities analyzed by vertebral fracture assessment (VFA) increases the risk of incident fractures in postmenopausal women: the FRODOS study.

Unlabelled: The incidence of vertebral fractures (VF) by vertebral fracture assessment (VFA) was 6.6% in postmenopausal women (FRODOS cohort) after 4 years of follow-up, increasing with prevalent VF and minor vertebral deformities, age, lower bone mass, glucocorticoid use, and rheumatoid arthritis. This study supports the usefulness of VFA to identify VF.

Usefulness of the Trabecular Bone Score for assessing the risk of osteoporotic fracture.

Introduction And Objectives: The trabecular bone score (TBS) is an imaging technique that assesses the condition of the trabecular microarchitecture. Preliminary results suggest that TBS, along with the bone mineral density assessment, could improve the calculation of the osteoporotic fracture risk. The aim of this study was to analyse TBS values and their relationship with the clinical characteristics, bone mineral density and history of fractures of a cohort of posmenopausal women.

Concordance between direct and indirect measurements of free 25-OH vitamin D.

Unlabelled: At present, data comparing the quantification methods for measurement of free vitamin D (direct assay [direct 25-OHD] and estimated by calculation [calculated 25-OHD]), are scarce. The aim of this study was to analyse the concordance between these two methods of 25-OHD analysis (direct vs. calculated).

Comparison of total, free and bioavailable 25-OH vitamin D determinations to evaluate its biological activity in healthy adults: the LabOscat study.

Unlabelled: Determination of different forms of 25-OHD (total, free and bioavailable) in healthy young women does not offer additional advantages over standard 25-OHD for evaluating vitamin D deficiency. In these subjects 25-OHD values <15 ng/ml would be more appropriate for defining this deficiency.

Introduction: Determination of 25-OH vitamin D serum levels (25-OHD) constitutes the method of choice for evaluating vitamin D deficiency.

Reference intervals for bone turnover markers in Spanish premenopausal women.

Background: The aims of this study were to establish robust reference intervals and to investigate the factors influencing bone turnover markers (BTMs) in healthy premenopausal Spanish women.

Methods: A total of 184 women (35-45 years) from 13 centers in Catalonia were analyzed. Blood and second void urine samples were collected between 8 a.

Prevalence of vertebral fractures and minor vertebral deformities evaluated by DXA-assisted vertebral fracture assessment (VFA) in a population-based study of postmenopausal women: the FRODOS study.

Unlabelled: Population-based studies performed with vertebral fracture assessment (VFA) morphometric technology are lacking in postmenopausal osteoporosis. In this study, we show a lower than expected prevalence of vertebral fractures, a high prevalence of minor vertebral deformities, and a clear association with clinical and densitometric parameters indicating the usefulness of this approach.

Introduction: Adequate epidemiological data on the prevalence of vertebral fractures (VF) is essential in studies of postmenopausal osteoporosis.

Distribution of serum βCTX in a population-based study of postmenopausal women taking into account different anti-osteoporotic therapies (the FRODOS Cohort).

This cross-sectional study evaluated the distribution of serum cross-linked C-telopeptides of collagen type I (βCTXs) in postmenopausal women, the characteristics of bone remodeling, and the factors influencing this bone marker, especially the use of anti-osteoporotic drugs. Women (n = 4,175) aged 59-70 years randomly selected from the community were invited to participate, measuring βCTXs and lumbar and femoral bone mineral density at recruitment. Risk factors for osteoporosis and the use of anti-osteoporotic treatment were collected with a structured questionnaire.

[Relationship between C-telopeptides of type I collagen serum values with bone mineral density and antiosteoporotic drug intake in postmenopausal women. Preliminary data from the FRODOS study].

Background And Objective: Few studies have addressed the role of bone turnover markers (BTM) in Spanish postmenopausal women. The goal of the study was to analyse the relationship between crosslinked C-telopeptides of type I collagen (betaCTXs) serum values and bone mineral density (BMD) and antiosteoporotic drug intake in a large sample of postmenopausal women.

Patients And Method: We have recruited 1495 women aged 59-70 years (15.

Macroscopic features of knee synovitis in early untreated Behçet disease and psoriatic arthritis.

In a previous study, we found that synovial immunopathology differs between Behçet disease (BD) and psoriatic arthritis (PsA). The objective of this study is to describe the macroscopic features of early untreated knee synovitis in BD and PsA. Fourteen consecutive patients with active early knee synovitis (seven BD and seven PsA) undergoing rheumatologic arthroscopy were assessed.

Vertebral morphometric X-ray absorptiometry in women with Colles' fracture.

Colles' fracture (CF) in younger postmenopausal women is associated with low bone mineral density (BMD) and with an increased risk of other osteoporotic fractures; however, the prevalence of vertebral deformities has been not studied in CF patients. Vertebral morphometry (MXA) using dual-energy X-ray absorptiometry (DXA) is a research tool developed to evaluate the presence of vertebral deformities, but its clinical use is still limited. The goals of this work were to know the prevalence of vertebral deformities in women with CF, to study the morphometric characteristics of height ratios, and to determine the correlation between MXA findings and BMD.

Association between Colles' fracture and low bone mass: age-based differences in postmenopausal women.

Colles' fracture (CF) in postmenopausal women has been linked to low bone mass at the lumbar spine and hip. However, the diverse methodological approaches of previous studies make the results difficult to compare and thus the implications of CF in osteoporosis daily clinical practice are not clear. We explored the association between CF and low bone mineral density (BMD) in an incident case-control study in 58 postmenopausal Spanish women aged 45-80 years with recent CF and in 83 population-based controls of the same age range.

[Diagnosis and treatment of postmenopausal osteoporosis after a Colles' fracture].

Objectives: To investigate whether the presence of Colles fracture leads to diagnostic studies or treatment of osteoporosis in postmenopausal women.

Design: Retrospective study with follow-up of incident cases.

Setting: Hospital General de Vic and Primary Care Centre Osona.

[Calcitonin prescriptions: an estimate of the expenditure due to inadequate prescription].

Background: The use of calcitonin is very common in patients diagnosed with osteoporosis. The objective of this study was to determine the percentage of adequate prescriptions of calcitonin for patients with osteoporosis and to estimate the costs due to inadequate prescription.

Patients And Methods: Observational study.

Coexistence of two antisynthetases in a patient with the antisynthetase syndrome.

We describe the immunologic findings in a patient with the antisynthetase syndrome characterized by prominent arthritis, lung fibrosis, and subclinical myositis. At disease onset and during the followup, this patient's serum showed 2 different subsets of antisynthetase autoantibodies: anti-Jo-1, which reacted with histidyl-transfer RNA (tRNA) synthetase by immunoblot and inhibited its enzymatic function; and anti-0J, which immunoprecipitated the multi-enzyme complex of synthetases, and reacted with lysyl-tRNA synthetase by immunoblot. This is the first report of anti-Jo-1 and another antisynthetase antibody being found together in the same patient.

Analysis of the association between chondrocalcinosis and osteoarthritis: a community based study.

Objectives: To analyse the association between chondrocalcinosis and osteoarthritis (OA) of the hands and knees in an unselected elderly rural population.

Methods: A community based cross sectional study was performed in individuals randomly selected from a previous epidemiological survey on the prevalence of chondrocalcinosis in people older than 60 years from Osona county, Catalonia, northeastern Spain. Radiological OA (grade 2 or more of Kellgren's classification) was evaluated in 26 individuals with chondrocalcinosis and in 104 controls.

[Diseases associated with articular chondrocalcinosis: an analysis of a series of 95 cases].

Background: There are different diseases which are associated with articular chondrocalcinosis (ACC) although in some it is debated whether this is a real association or an accidental coexistence. The aim of the present study was to analyze the prevalence and type of associated diseases in a series of patients with ACC and to compare with other series in the literature, as well as determine the performance of a protocol directed to the search for such diseases in patients with ACC.

Method: A total of 95 patients diagnosed of ACC and attended in the out patients department of Rheumatology in a general hospital over a 5 year period (1987-1991) were included in a protocol specially designed to search for diseases associated to ACC.
