Generation of connectivity-preserving surface models of multiple sclerosis lesions.
Progression of multiple sclerosis (MS) results in brain lesions caused by white matter inflammation. MS lesions have various shapes, sizes and locations, affecting cognitive abilities of patients to different extents. ⋯ This tool allows users to create 3D models of lesions quickly and to visualize the lesions and brain tissues using various visual attributes and configurations. The software package is based on breadth-first search based 3D connected component analysis and a 3D flood-fill based region growing algorithm to generate 3D models from binary or non-binary segmented medical image stacks.

Comparative StudyComparison of a disposable bougie versus a newly designed malleable bougie in the intubation of a difficult manikin airway.
The endotracheal bougie is used for difficult intubations when only a minimal glottic view is obtained. Standard bougies are designed for use during direct, line-of-sight viewing of the glottic opening. ⋯ A malleable bougie with an imbedded internal wire was created to enable intubators to shape the curve to best fit a difficult airway. This pilot study examined the malleable bougie compared to the SunMed bougie in a simulated difficult airway intubation using video laryngoscopy.

Observing effectiveness of pathology ordering controls in emergency departments.
To demonstrate application of data integration technology for observing the effectiveness of interventions to control pathology orders in Emergency Departments. ⋯ Pathology ordering can be reduced using sustainable protocols. This work has demonstrated HDI capability to extract and link pathology data efficiently to evaluate an ED intervention.

The single source architecture x4T to connect medical documentation and clinical research.
Clinical trials often require large and redundant documentation efforts, because information systems in patient care and research are separated. In two clinical trials we have assessed the number of study items available in the clinical information system for re-use in clinical research. ⋯ Based on this analysis we have designed and implemented an architecture for an integrated clinical trial documentation workflow. Key aspects are the re-use of existing medical routine data and the integration into current documentation workflows.

Toward a simulation and assessment method for the practice of camera-guided rigid bronchoscopy.
We have developed a way to measure performance during a camera-guided rigid bronchoscopy using manikin-based simulation. In an effort to measure contact pressures within the airway during a rigid bronchoscopy, we instrumented pressure sensors in a commercially available bronchoscopy task trainer. ⋯ However, novices touched a greater number of areas than experts, showing that novices induce a higher number of unnecessary soft-tissue contact compared to experts. Moreover, our results show that experts exert significantly less soft tissue pressure compared to novices.
