Background: The opioid use disorder is an international public health problem. Over the past 20 years it has been the subject of numerous publications concerning patients treated for chronic pain other than cancer-related. Patients with cancer-related pain are also at risk of opioid use disorder. The primary objective of this literature review was to determine the prevalence of opioid use disorder in patients with cancer-related chronic pain. Its secondary objective was to identify the characteristics of these opioid users. Methods: This is a literature review of studies published over the last twenty years, from 1 January 2000 to 31 December 2020 identified by searching the three main medical databases: Pubmed, Cochrane, and Embase. A meta-analysis took account of between and within-study variability with the use of random-effects models estimated by the DerSimonian and Laird method. Results: The prevalence of opioid use disorder was 8% (1–20%) and of the risk of use disorder was 23.5% (19.5–27.8%) with I2 values of 97.8% and 88.7%, respectively. Conclusions: Further studies are now needed on the prevalence of opioid use disorder in patients treated for cancer-related chronic pain. A screening scale adapted to this patient population is urgently needed.

by the Count of Saint-Périer and given to the laboratory of Paleontology in the National Museum of Natural History of Paris a few months later, the Venus of Lespugue can be seen as a major Palaeolithic work. A lot of theories have tried to explain its meaning and function in Palaeolithic society, but its biography within the museum still remained to be done. This biography will help to examine the situation of the whole of Prehistory within the National Museum of Natural History, to understand the evolution of this institution during the last century, and to reevaluate the rank of masterpiece that has been attributed to the Venus in the new Musée de l'Homme.

Entre 1990 et 2014, des « objets ambassadeurs » de la culture kanak, conservés dans des musées à travers le monde, effectuent des retours temporaires sur leur territoire d’origine, la Nouvelle-Calédonie. Parmi eux, une statuette féminine des collections du musée du quai Branly – Jacques Chirac permet, grâce aux trois voyages qu’elle entreprend pour être exposée à Nouméa, d’illustrer les enjeux de ces échanges entre institutions muséales, dans le but d’une gestion partagée du patrimoine kanak dispersé. Ce programme de coopération internationale met également en évidence la place des musées et des collections muséales dans les enjeux de représentation, de diplomatie culturelle et de revendications postcoloniales.
