A prospective analysis of the incidence of paranasal sinus opacification in 100 patients referred for cranial computerized tomography (CT) for non-sinus related problems is described. The findings were correlated with symptomatic assessment. Twenty-seven per cent of asymptomatic patients had sinus opacification. The study illustrates the importance of careful clinical correlation when interpreting CT scans of the paranasal sinuses.

We assessed the RHC view in acute elbow trauma and attempted to evaluate the significance of displaced fat pads in such cases. Subjects and MethodsSubjects were 130 consecutive patients presenting with acute elbow trauma. A total of 135 examinations were performed in these patients. The following views were obtained immediately:AP, true lateral (elbow flexed to 90#{176} with the hand and wrist at 90#{176} to the radiographic table), conventional radial-head (two views with the elbow flexed to 900: the first with the palm of the hand in contact with the table and the second with the hand rotated internally), and RHC.All radiographs routinely were reported by two of us (M. A. H-C., P. J. S.) together at the time of presentation.Patients with abnormal fat pads but without bony injury were requested to return for repeat examination 2 weeks later. A visible dorsal fat pad and/or displacement of the anterior fat pad was considered to be abnormal. At the end of the study, all radiographs of any patient in whom an abnormality had been detected were reviewed. All radiographs from all cases were sorted randomly and viewed individually by a radiology senior registrar (P. J. S.) and a consultant (M. C.). Each view was scored for the presence or absence of a fracture. At the same time, displacement of fat pads was assessed on the true lateral view. Finally, the radiographs were re-sorted into complete sets for each patient, then reviewed by the two observers together. A consensus decision was made on radiographs in which there had been previous disagreement.In those patients with fractures, the view most clearly demonstrating the fracture and the bony displacement was selected from each set.

The use of knowledge management tools enabling distributed collaboration and information sharing supports, and indeed shapes, how work is done in industry today. The panel chosen, all having extensive international experience, reflects directly the realities of a digital, global workforce and the new opportunities for information technology to support it. Starting off the panel will be a consultant from one of the leading providers of tools and research on innovation, who will outline the latest thinking on what is necessary for effective innovation in the workplace, with a focus on how this is enabled by knowledge management tools.The changing role of the information professional is illustrated clearly by the three
