Osteoarthritis (OA) can be a progressive disabling disease, which results from the pathological imbalance of degradative and reparative processes, with concomitant inflammatory changes. The synovium, bone, and cartilage are each well established sites involved in the pathophysiological mechanisms that lead to progressive joint degeneration. The search for disease-modifying osteoarthritis drugs, DMOADs, has been hampered by several factors, including the variable progression of disease, the lack of specificity and sensitivity of standard radiography, and the fact that the slowing of radiographic progression may not result in corresponding improvement in pain and function. As a result, there is general agreement that development of DMOADs will be facilitated by advances in imaging and the validation of chemical biomarkers. Such biomarkers should be useful tools that will identify patients at risk for disease progression and predict responses to candidate structure-modifying drugs

Percutaneous tracheostomy has become a common alternative to the classical open tracheostomy because of its convenience, cost effectiveness, and decreased complication rates. We retrospectively reviewed our intensive care practice using a guidewire dilatating forceps percutaneous tracheostomy technique with an endotracheal tube, as compared with the Classic Laryngeal Mask Airway (LMA) for these procedures. From 1998 to 2004, 274 patients underwent a tracheostomy procedure. Two-hundred-fifty-four (92.7%) of these patients underwent a guidewire dilatating forceps tracheostomy and 20 (7.3%) underwent a surgical tracheostomy. In the guidewire dilatating forceps group, 188 (74%) were performed by endoscopy via LMA-guided bronchoscopy, and 66 (26%) were performed through an endotracheal tube. Endoscopic views obtained via the LMA were subjectively better than those obtained with the endotracheal tube. Acute complications were significantly more frequent when using an endotracheal tube as compared with the LMA (6 of 66 versus 4 of 188; P = 0.022 Fisher's exact test, odds ratio = 4.6). There was a significant difference in terms of acute (10 of 254 versus 6 of 20; P < 0.001, odds ratio = 10.5) and chronic (0 of 254 versus 4 of 20; P < 0.001) complications between the 2 groups. There were no ventilatory complications or reports of gastric aspiration. The LMA provides a safe and effective alternative to an endotracheal tube for airway management during guidewire dilatating forceps tracheostomies in selected patients

Drug discovery and delivery to retard the degeneration of joint tissues are challenging. Current treatment is generally inadequate. This commentary places in perspective the inadequacy characteristic of existing therapeutics and the promising developments embodied in the newer therapeutics administered via the oral or intra-auricular routes
