Background: Establishment of a cancer registry is a complex process that requires substantial resources and careful planning. There are numerous resources available to provide guidance for this, which include guidelines and frameworks of varying quality. It is the authors' goal to identify evidence-based recommendations within the literature to help guide the process of designing a new registry with optimal efficiency, workability and data use. The objective of this study is to examine the primary literature for evidence-based recommendations on how to design and establish a cancer registry, with a focus on literature which analyses the performance and usefulness of already established registries or guidelines., Methods: An electronic search was completed in MEDLINE, CINAHL, EMCARE, SCOPUS and the Cochrane Database of Systematic Reviews. Recommendations were extracted from the identified articles and collated as themes., Results: Nine articles of varying quality were included in the review. Recommendations obtained from the literature included broad themes of the importance of clinician involvement, establishment of clear data definitions, number of variables used, inbuilt strategies to improve quality and completeness of data, considerations of costs, an 'opt-out' strategy for ethics and privacy and flexibility of the system., Conclusion: This review concluded that there is a large gap in the primary literature for evidence-based recommendations on the design and establishment of cancer registries. The included articles established a small scope of relevant themes, which were largely non-specific. This area of deficiency provides an opportunity for future research, which would further strengthen the quality of current or new guidelines in cancer registry establishment., (© 2020 Royal Australasian College of Surgeons.)

Background: Unicompartmental knee arthroplasty is a popular alternative to total knee replacement in selected patients. Component alignment has not yet been described by computer-assisted tomography (CAT) imaging techniques; these have been developed for total knee arthroplasty analysis. The aims of this study were to report two new technologies; a new unicompartmental knee arthroplasty system was radiographically assessed with a new CAT scan protocol., Methods: In a consecutive cohort study, 60 knees were analysed by the 'UniCAT Protocol'. Patients were implanted with a unicompartmental knee arthroplasty system that uses a unique ligament tensor for femoral component alignment. The uniCAT protocol requires a long anteroposterior and lateral scout scan to measure limb alignment and component orientation. A spiral computer-assisted tomography at the knee is used to measure component rotation. The total scan time was 20 s with a calculated unshielded radiation dose of 1 mSv or less., Results: The mechanical axis had a mean of 2.7 degrees varus. Femoral components were implanted with a mean of 0.37 degrees valgus and 1.3 degrees flexion. Tibial components were implanted with a mean 3.47 degrees varus and 5.1 degrees posterior slope. Femoral components were externally rotated a mean of 3.36 degrees, tibial components were externally rotated 6.59 degrees from the posterior tibia and 5.68 degrees from the transepicondylar axis., Conclusion: The UniCAT protocol uses less radiation than whole-limb spiral scans and is a method that can be used with all modern computer-assisted tomography machines. The coronal and sagital alignment results compare favourably with previous published reports without computer-assisted tomography. Component rotation has not previously been reported and its implications are yet to be defined.

26 December 2004 is a date that changed the lives of incalculable numbers of persons the world over as a result of the Asian tsunami. Krabi Province was one of the more severely affected areas of Thailand, with many of the dead and injured being non-Thai, persons who were holidaying during the peak tourist season. Some injury types were comparatively underrepresented, such as head, thoracic and abdominal trauma. Does the classic trimodal distribution of death following injury help explain the types of injuries seen in the survivors of the disaster? Data are incomplete at this point in time, but with time it may be found that the trimodal model displays the pattern of death in mass casualty disaster situations. This may aid in the development of specific strategies to deal with similar events in the future.
