Pain relief can occur despite insufficient lesion filling. In most patients, intradiskal and paravertebral leaks of cement had no clinical importance.

Adiponectin is the most relevant adipokine negatively associated with BMD, independent of gender and menopausal status. Inconsistent associations between adipokines and BMD are probably confounded by body composition, in particular fat mass parameters.

CT may be a useful noninvasive tool for recognition of RA-associated lung disease with special emphasis on bronchial and bronchiolar changes.

The diagnosis of osteoporosis rests on areal bone mineral density (BMD) measurement using DXA. Cancellous bone microarchitecture is a key determinant of bone strength but cannot be measured using DXA. To meet the need for a clinical tool capable of assessing bone microarchitecture, the TBS was developed. The TBS is a texture parameter that evaluates pixel gray-level variations in DXA images of the lumbar spine. The TBS variations may reflect bone microarchitecture. We explain the general principles used to compute the TBS, and we report the correlations between TBS and microarchitectural parameters. Several limitations of the TBS as it is used now are pointed out. We discuss data from currently available clinical studies on the ability of the TBS to identify patients with fractures and to evaluate the fracture risk. We conclude that this new index emphasizes the failure of the BMD T-score to fully capture the fragility fracture risk. However, although microarchitecture may influence the TBS, today, to the best of our understanding, there is no sufficient evidence that a TBS measurement provides reliable information on the status of the bone microarchitecture for a given patient. The TBS depends on gray-level variations and in a projectional image obtained in vivo, these variations can have many causes. Nevertheless, as clinical studies suggest that the TBS predicts the risk of fracture even after adjustment for BMD, we are encouraged to learn more about this score. Additional studies will have to be performed to assess the advantages and limitations of the TBS, in order to ensure that it is used appropriately in clinical practice.

Results-A significant decrease of FEV1/ FVC, FEF25%, FEF50%, FEF75%, FEF25-75%, and TLCO was observed (p<0.05) and 13.2% of the patients had a small airways involvement defined by a decrease of FEF25-75% below 1.64 SD. The most frequent HRCT findings were: bronchiectasis (30.5%), pulmonary nodules (28%), and air trapping (25%). The patients with small airways involvement had a high frequency of recurrent bronchitis (75% v 34%, p=0.05) and bronchiectasis (71% v 23%, p=0.019). The patients with bronchiectasis were characterised by low values of FEV1, FVC, FEF25-75%, and TLCO (p<0.01), a high prevalence of small airways involvement (29% v 5%, p=0.019), and a low prevalence of HLA DQA1 *0501 allele (14% v 33%, p<0.05). Conclusion-This study suggests a significant association between small airways involvement on PFTs and bronchiectasis on HRCT in unselected RA patients.

Observational studies have indicated a high but heterogeneous prevalence of low bone mineral density for adult patients with cystic fibrosis. Fracture complications were also described. The objective of this study was to determine the prevalence of osteoporosis, osteopenia, and fractures among adult patients with cystic fibrosis. A systematic literature review was conducted using electronic databases. The keywords used were "cystic fibrosis [MeSH] AND bone density." Original studies were eligible if they reported the prevalence of osteoporosis and/or osteopenia and/or fractures in adult patients with cystic fibrosis. A meta-analysis of pooled proportions was performed. Heterogeneity was tested with the Cochran Q statistic, and in the case of heterogeneity a random effect model was used. Of 117 studies, 12 were selected, i.e., that represented a total of 1055 patients. Mean age ranged from 18.5 to 32 years (median: 28.2 years). Mean body mass index ranged from 19.9 to 22.4 (median: 20.7); 53.8% were men. The pooled prevalence of osteoporosis in adults with cystic fibrosis was 23.5% (95% CI, 16.6-31.0). The pooled prevalence of osteopenia was 38% (95% CI, 28.2-48.3). The pooled prevalences of radiological vertebral fractures and nonvertebral fractures were 14% (95% CI, 7.8-21.7) and 19.7% (95% CI, 6.0-38.8), respectively. In conclusion, this systematic literature review with meta-analysis emphasized the high prevalence of osteopenia and osteoporosis in young adults with cystic fibrosis. The prevalence of fracture was also high.

Summary Osteoporosis represents a significant and increasing healthcare burden in Europe, but most patients at increased risk of fracture do not receive medication, resulting in a large treatment gap. Identification of patients who are at particularly high risk will help clinicians target appropriate treatment more precisely and cost-effectively, and should be the focus of future research.
