InvaCost, a public database of the economic costs of biological invasions worldwide.

Biological invasions are responsible for tremendous impacts globally, including huge economic losses and management expenditures. Efficiently mitigating this major driver of global change requires the improvement of public awareness and policy regarding its substantial impacts on our socio-ecosystems. One option to contribute to this overall objective is to inform people on the economic costs linked to these impacts; however, until now, a reliable synthesis of invasion costs has never been produced at a global scale. Here, we introduce InvaCost as the most up-to-date, comprehensive, harmonised and robust compilation and description of economic cost estimates associated with biological invasions worldwide. We have developed a systematic, standardised methodology to collect information from peer-reviewed articles and grey literature, while ensuring data validity and method repeatability for further transparent inputs. Our manuscript presents the methodology and tools used to build and populate this living and publicly available database. InvaCost provides an essential basis (2419 cost estimates currently compiled) for worldwide research, management efforts and, ultimately, for data-driven and evidence-based policymaking.

[Post-traumatic paraosteoarthropathy of the hip. Analysis with x-ray computed tomography and 3-dimensional reconstruction. 2 cases]. / Paraostéoarthropathie de hanche post-traumatique. Analyse en TDM et reconstruction 3D. A partir de 2 observations.

Two cases of paraosteoarthropathy developed soon after hip trauma and without associated spinal disorders are described. CT perfectly discriminates ectopic bone formation from osseous fragments and calcified hematoma. These lesions display different signs and have different locations, which allows an easy differentiation. The aetiology of these traumatic osteomas (hip trauma associated with surgical repair in one case coma in the other) is compared to literature. The effectiveness of CT with 3D reconstruction is emphasized in paraosteoarthropathy and hip trauma screening.
