Objectives: To assess the prevalence of inflammation in subjects with chronic painful knee osteoarthritis (OA), as determined by the presence of synovitis or joint effusion at ultrasonography (US); and to evaluate the correlation between synovitis, effusion, and clinical parameters. Methods: A cross sectional, multicentre, European study was conducted under the umbrella of EULAR-ESCISIT. Subjects had primary chronic knee OA (ACR criteria) with pain during physical activity >= 30 mm for at least 48 hours. Clinical parameters were collected by a rheumatologist and an US examination of the painful knee was performed by a radiologist or rheumatologist within 72 hours of the clinical examination. Ultrasonographic synovitis was defined as synovial thickness >= 4 mm and diffuse or nodular appearance, and a joint effusion was defined as effusion depth >= 4 mm. Results: 600 patients with painful knee OA were analysed. At US 16 (2.7%) had synovitis alone, 85 (14.2%) had both synovitis and effusion, 177 (29.5%) had joint effusion alone, and 322 (53.7%) had no inflammation according to the definitions employed. Multivariate analysis showed that inflammation seen by US correlated statistically with advanced radiographic disease (Kellgren-Lawrence grade >= 3; odds ratio (OR) = 2.20 and 1.91 for synovitis and joint effusion, respectively), and with clinical signs and symptoms suggestive of an inflammatory "flare'', such as joint effusion on clinical examination (OR = 1.97 and 2.70 for synovitis and joint effusion, respectively) or sudden aggravation of knee pain (OR = 1.77 for joint effusion). Conclusion: US can detect synovial inflammation and effusion in painful knee OA, which correlate significantly with knee synovitis, effusion, and clinical parameters suggestive of an inflammatory "flare''.

BACKGROUND: Synovial inflammation (as defined by hypertrophy and effusion) is common in osteoarthritis (OA) and may be important in both pain and structural progression. OBJECTIVE: To determine if decision rules can be devised from clinical findings and ultrasonography (US) to allow recognition of synovial inflammation in patients with painful knee OA. METHODS: A EULAR-ESCISIT cross sectional, multicentre study enrolled subjects with painful OA knee who had clinical, radiographic, and US evaluations. A classification and regression tree (CART) analysis was performed to find combinations of predictor variables that would provide high sensitivity and specificity for clinically detecting synovitis and effusion in individual subjects. A range of definitions for the two key US variables, synovitis and effusion (using different combinations of synovial thickness, depth, and appearance), were also included in exploratory analyses. RESULTS: 600 patients with knee OA were included in the analysis. For both knee synovitis and joint effusion, the sensitivity and specificity were poor, yielding unsatisfactory likelihood ratios (75% sensitivity, 45% specificity, and positive LR of 1.36 for knee synovitis; 71.6% sensitivity, 43.2% specificity, and positive LR of 1.26 for joint effusion). The exploratory analyses did not improve the sensitivity and specificity (demonstrating positive LRs of between 1.26 and 1.57). CONCLUSION: Although it is possible to determine clinical and radiological predictors of OA inflammation in populations, CART analysis could not be used to devise useful clinical decision rules for an individual subject. Thus sensitive imaging techniques such as US remain the most useful tool for demonstrating synovial inflammation of the knee at the individual level. [less ▲]

This paper reformulates the governing equations of an extensible elastic rod by reference to a given spatial curve. This Eulerian formulation is motivated by the need to solve efficiently the constrained elastica problem encountered in many medical and engineering applications, in which a thin rod is inserted in a tortuous conduit. The Eulerian reformulation of the equations hinges on the restatement of the rod local equilibrium in terms of derivatives with respect to the curvilinear coordinate associated with the reference curve and the description of the rod deflection as a perturbation of this curve. The originality of the proposed formulation lays in the axially unconstrained character of the resulting system such that the determination of the rod configuration between two fixed points reduces to the resolution of a classical boundary value problem.

Though the themes of ‘counter-jihad’ and ‘islamofascism’ contributed to somehow renew the far right discourse, it is arguable that the core structure of the underlying political narrative remained unchanged – ‘Muslims’ merely taking the place of Jews in the role of ‘enemies from within’, while Islam superseded communism as the major totalitarian threat to the Western world. Taken as a globalised narrative, counter-jihad discourse displays striking differences between its North American and European versions, the former emphasizing Islam as a rather external, terrorist threat, whereas the latter denounces it as a cultural peril, resulting from an alleged failure of multiculturalism both as a policy and as an ideology. The ‘Eurabia’ conspiracy theory often serves as the bedrock of these narratives: a deliberate, albeit covert policy framework set by European and Arab leaders in order to gradually establish a Muslim majority in Europe. Still, the question remains whether these new discursive entities function as pure ‘identity markers’ or reveal original, unprecedented forms of ‘imagined communities’ (B. Anderson). In this respect, the Eurabian scenario contrasts sharply with the traditional far right rhetoric of decline: as it sets a seemingly inescapable, dystopian horizon, it paradoxically presupposes the existence of an organized political community actually able to do something to prevent that dark future from happening. Through ‘heuristics of fear’ (H. Jonas), Eurabia aims at creating a community of politically aware individuals and empowering them for current and future struggles. In our paper, we propose to analyse such ‘imaginary institution’ of a counter-jihad society. Using controversy mapping tools to show the relation between actors of the movement, we will particularly focus on the blogging community and its notably prominent role in the spreading and structuring of the Eurabian dystopia.
