Purpose: The aim of this research was to assess the dimensional accuracy of orbital prostheses based on reversed images generated by computer-aided design/computer-assisted manufacturing (CAD/CAM) using computed tomography (CT) scans. Materials and Methods: CT scans of the faces of 15 adults, men and women older than 25 years of age not bearing any congenital or acquired craniofacial defects, were processed using CAD software to produce 30 reversed three-dimensional models of the orbital region. These models were then processed using the CAM system by means of selective laser sintering to generate surface prototypes of the volunteers` orbital regions. Two moulage impressions of the faces of each volunteer were taken to manufacture 15 pairs of casts. Orbital defects were created on the right or left side of each cast. The surface prototypes were adapted to the casts and then flasked to fabricate silicone prostheses. The establishment of anthropometric landmarks on the orbital region and facial midline allowed for the data collection of 31 linear measurements, used to assess the dimensional accuracy of the orbital prostheses and their location on the face. Results: The comparative analyses of the linear measurements taken from the orbital prostheses and the opposite sides that originated the surface prototypes demonstrated that the orbital prostheses presented similar vertical, transversal, and oblique dimensions, as well as similar depth. There was no transverse or oblique displacement of the prostheses. Conclusion: From a clinical perspective, the small differences observed after analyzing all 31 linear measurements did not indicate facial asymmetry. The dimensional accuracy of the orbital prostheses suggested that the CAD/CAM system assessed herein may be applicable for clinical purposes. Int J Prosthodont 2010;23:271-276.

Aim of study: This study sought to determine whether multidisciplinary case conference reviews improved outcomes for nursing home residents, and the effects of this team approach to resident care on carers, including the hands-on carers employed by the nursing home, and health professionals. Method: 245 residents of three Canberra nursing homes were enrolled in this non-randomised controlled trial. The intervention consisted of sessions of three case conference reviews held between 10/4/96 and 4/12/96. These sessions were attended by the General Practitioners (GPs) of the residents discussed, the GP project officer from the ACT Division of General Practice, a clinical pharmacist, senior nursing staff, other health professionals eg physiotherapist, and occasionally the resident concerned or their representative. At each review, a case presentation by the resident's GP was followed by a multidisciplinary discussion of all aspects, medical and non-medical, of the resident's care. The review concluded with a management plan for the resident. In total 75 residents were reviewed. Main outcome measures: Medication use and cost, and mortality. Results: One month after the reviews were completed comparisons between those who were reviewed and those who were not showed non-significant reductions in medication orders, medication cost, and mortality in the reviewed group. Many of the 92 recommendations in the management plans that were carried out benefited the residents (n=37) and/or carers (n=24). The responses of the GPs and the Directors of Nursing to the reviews were overwhelmingly positive. Conclusion: Recommendations arising from multidisciplinary case conferences were carried out to the benefit of patients and carers. Given the support shown by key stakeholders, multidisciplinary conferences should be used more.
