Drug needle fragments in subcutaneous tissue may cause local symptoms (usually pain and infections), but they have also been identified as causing emboli to organs. The literature has described numerous case reports of people who inject drugs (PWIDs) and have retained needle fragments. The prevalence of the condition is not known, and the researchers therefore aim to perform the first cross-sectional study of PWIDs to estimate how common needle fragment retentions are and what their risk factors are in this population.",[86,87,88,89,90],"Drug Abuse, Intravenous","Substance Dependence","Needle Injury","Soft Tissue Injuries","Foreign Bodies",[92,93,94],"Intravenous drug use","needle retention","needle fragment","2023-05-30",{"date":97,"type":98},"2023-06-01","ACTUAL",{"date":100,"type":98},"2023-05-25",{"date":102,"type":82},"2028-11-15",{"name":5,"class":6},1]
