We assessed the efficacy, safety, and acceptability of this treatment in a large, randomized trial. METHODS: A total of 652 women with a first-trimester pregnancy failure (anembryonic gestation, embryonic or fetal death, or incomplete or inevitable spontaneous abortion) were randomly assigned to receive 800 μ g of misoprostol vaginally or to undergo vacuum aspiration (standard of care) in a 3:1 ratio. The misoprostol group received treatment on day 1, a second dose on day 3 if expulsion was incomplete, and vacuum aspiration on day 8 if expulsion was still incomplete. Surgical treatment (for the misoprostol group) or repeated aspiration (for the vacuum-aspiration group) within 30 days after the initial treatment constituted treatment failure. RESULTS: Of the 491 women assigned to receive misoprostol, 71 percent had complete expulsion by day 3 and 84 percent by day 8 (95 percent confidence interval, 81 to 87 percent). Treatment failed in 16 percent of the misoprostol group and 3 percent of the surgical group (absolute difference, 12 percent; 95 percent confidence interval, 9 to 16 percent) by day 30. Hemorrhage or endometritis requiring hospitalization was rare (1 percent or less in each group), with no significant differences between the groups. In the misoprostol group, 78 percent of the women stated that they would use misoprostol again if the need arose and 83 percent stated that they would recommend it to others. CONCLUSIONS: Treatment of early pregnancy failure with 800 μ g of misoprostol vaginally is a safe and acceptable approach, with a success rate of approximately 84 percent.展开更多

Endometrial biopsy slides randomly selected from a multicenter study testing the utility of biopsy in the diagnosis of infertility were distributed to three gynecologic pathologists, who estimated cycle day using standard criteria. Readers were blinded to the purpose of the study, patient age, fertility status, or timing of biopsy relative to LH surge or next menses. Multicenter academic research programs in reproductive medicine. Eightytwo women with proven fertility, 83 infertile patients. Endometrial biopsy during midluteal (days 21-22) or late (days 26-27) luteal phase. Intraclass correlation coefficient (ICC), kappa. Overall agreement was excellent (ICC 0.88); addition of readings by local pathologists decreased ICC only slightly. In subgroup analyses, ICCs were lowest for infertile women during the midluteal phase (0.65 vs. 0.71 for fertile women in the midluteal phase, and 0.88-0.90 for both groups in the late luteal phase). Intraobserver reliability was excellent (0.9-0.99). Agreement for diagnoses of outofphase was only moderate, with kappa values between 0.4 and 0.6. Observer variability in dating the endometrium was greatest in infertile women during the window of implantation.展开更多
