Equivalence between vaginal and sublingual administration could not be demonstrated overall. Vaginal administration showed a higher effectiveness than sublingual administration in terminating second trimester pregnancies, but this result was mainly driven by nulliparous women. Fever was more prevalent with vaginal administration. Registered with International Standard Randomized Controlled Trial number ISRCTN72965671.
The IUD ML Cu375 was inserted, after bacteriological screening, into 620 women who were observed for 12 months. Bacterioscopy and, when needed, bacteriology of vaginal smears were performed 7 days, and 1, 3, 6 and 12 months after insertion. During the 12 months, pelvic inflammatory disease (PID) was diagnosed in 4 patients (0.6%) and sexually transmitted disease (STD) in 73 patients (11.8%). Careful selection of patients and bacteriological screening can effectively reduce the risk of bacterial contamination and subsequent development of PID.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
