Impact of partial prelabor rupture of membranes at term on labor and on obstetrical and neonatal outcomes: A retrospective case-control study.

OBJECTIVE: This study aimed to assess whether a partial term prelabor rupture of membranes (partial TPROM) had an impact on the spontaneous onset of labor compared to complete TPROM. METHODS: We performed a retrospective study in a French level III maternity hospital. We included all singleton cephalic pregnancies presenting with prelabor rupture of membranes ≥37 weeks gestational age. Patients with a partial TPROM (P group) were compared to patients with a complete TPROM (C group). Induction of labor was performed following expectative management of 24-48 h, and antibiotic prophylaxis was started 12 h after rupture. Our main outcome measure was the rate of patients who had spontaneous labor 24 h following prelabor rupture. RESULTS: Overall, 389 women were included in the study, 148 in the P group, 241 in the C group. The proportion of women who went into spontaneous labor in the 24 h following TPROM was significantly lower in the P group (45% vs 64%, P < 0.001). A partial TPROM was a predictive factor for absence of labor at 24 h following rupture (adjusted odds ratio: 0.44 [0.29-0.68]). There were more cases of induction of labor (50% vs 20%, P < 0.001) and antibiotic prophylaxis (91% vs 73%, P < 0.001) in the P group. However, obstetrical and neonatal outcomes were comparable between the two groups. CONCLUSION: Compared to complete TPROM, partial TPROM is associated with a lower probability of spontaneous labor in the 24 h following rupture. The persistence of a residual membrane has been identified as a risk factor for delaying labor beyond 24 h.

Transvaginal radiofrequency ablation of a myoma in 10 key steps.

OBJECTIVE: To describe transvaginal radiofrequency ablation of myomas (TRAM) in 10 key steps. DESIGN: Video article. SETTING: University hospital. PATIENT(S): A 38-year-old woman presented with menometrorrhagia and consequent chronic anemia (hemoglobin 8.5 g/dL) caused by a cervical myoma measuring 51 cm3. Initially, a cervicovaginal embolization was performed, but without any improvement in symptoms. Given the complex position of the myoma (close proximity to the uterine arteries), as well as the patient's desire for future pregnancies, a TRAM was proposed. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Volume of myoma and menometrorrhagia 6 months after treatment. RESULT(S): Not applicable. CONCLUSION(S): Transvaginal radiofrequency ablation of myomas is a quick, simple, minimally invasive, and easily reproducible technique. It could be an interesting alternative to the conventional laparoscopic and open-surgical treatments of myomas. There is a lack of high-quality data establishing TRAM safety in infertility and pregnancy. The only available radiofrequency ablation device in the United States has specific language stating that this procedure is not recommended for women considering future pregnancy.

Comparison of two cancellation strategies to lower the risk of multiple pregnancies in gonadotropin stimulated intrauterine insemination cycles.

OBJECTIVE: To compare two cancellation policies in controlled ovarian stimulation-intrauterine insemination (COS-IUI) cycles to lower the risk of multiple pregnancies (MP). DESIGN: We performed a bicentric retrospective cohort study in two academic medical centers: Angers (group A) and Besançon (group B) University Hospitals. We included 7056 COS-IUI cycles between 2011 and 2019. In group A, cancellation strategy was based on an algorithm taking into account the woman's age, the serum estradiol level, and the number of follicles of 14 mm or greater on ovulation trigger day. In group B, cancellation strategy was case-by-case and physician-dependent, based on the woman's age, number of follicles of 15 mm or greater, and the previous number of failed COS-IUI cycles, without any predefined cut-off. Our main outcome measures were the MP rate (MPR) and the live-birth rate (LBR). RESULTS: We included 884 clinical pregnancies (790 singletons, 86 twins, and 8 triplets) obtained from 6582 COS-IUI cycles. MPR was significantly lower in group A compared with group B (8.1% vs 13.3%, P = 0.01), but LBR were comparable (10.8% vs 11.8%, P = 0.19). Multivariate logistic regression found the following to be risk factors for MP: the "cancellation strategy" effect (adjusted odds ratio [aOR] 1.63, 95% confidence interval [CI] 1.02-2.60) and the number of follicles of 14 mm or greater (aOR 1.39, 95% CI 1.16-1.66). Cycle cancellation rate for excessive response was significantly lower in group A compared with group B (1.3% vs 2.4%, P < 0.001). CONCLUSIONS: The use of an algorithm based on the woman's age, serum estradiol level and number of follicles of at least 14 mm on trigger day allows the MPR to be reduced without impacting the LBR.
