Transient ovarian torsion in a pregnant woman after vitrified-warmed embryo transfer: a case report.

Assisted reproduction is a risk factor for adnexal torsion due to ovarian hyperstimulation and increased incidence of twin pregnancy. Both risk factors can be eliminated in frozen embryo transfers, but in our case ovarian torsion occurred after the use of an aromatase inhibitor (Femara) in endometrium preparation due to the presence of corpus luteum. Case presentation: G2P1+0 presented at 7 weeks gestation after vitrified-warmed embryo transfer with right loin pain and mild right iliac pain and tenderness. Ultrasound examination revealed transient or incomplete ovarian torsion. The presentation of the case was somewhat misleading and the transient nature of the torsion provided an opportunity for the conservative management of the case. In conclusion, ovarian torsion is still an undesired event, even after single embryo transfers and in vitrified-warmed cycles. Clinical and ultrasound follow-up precluded the need for surgery in our case.

An Ultrasound Scoring Model for the Prediction of Intrapartum Morbidly Adherent Placenta and Maternal Morbidity: A Cross-Sectional Study.

OBJECTIVE: To design an ultrasound scoring model for the prediction of the intrapartum morbidly adherent placenta (MAP) and maternal morbidity. PATIENTS AND METHODS: 114 females with singleton pregnancies ≥ 28 weeks of gestation referred for suspicion of MAP were included. All patients underwent examination by two-dimensional ultrasound with the color Doppler setting. Five signs were evaluated: the retroplacental echolucent space, placental lacunae, the hyperechoic uterine-bladder interface, retroplacental myometrium thickness, and subplacental, uterine serosa-bladder wall, intraplacental and bladder wall vascularity. We designed a score ranging from 0-8.5 points, including the five signs according to their odds ratios and evaluated its prediction for MAP and maternal morbidity. RESULTS: Using multivariate logistic regression, all ultrasound signs were significant dependent predictors for both MAP and maternal morbidity (myometrium thickness < 1 mm followed by lacunae ≥ 4 and lost retroplacental echolucent space). The only independent predictors for MAP were myometrium thickness < 1 mm and lacunae ≥ 4, while myometrium thickness < 1 mm and lost retroplacental echolucent space were predictive for maternal morbidity. The score showed a perfect agreement with MAP and a good one for maternal morbidity. CONCLUSION: Application of the score we designed can improve the ultrasound diagnosis of MAP and the maternal outcome.

Protecting Ovaries During Chemotherapy Through Gonad Suppression: A Systematic Review and Meta-analysis.

OBJECTIVE: To estimate whether gonadotropin-releasing hormone (GnRH) analog administration during chemotherapy can protect against development of ovarian toxicity. DATA SOURCES: MEDLINE (1966 to present), EMBASE (1980 to present), Cochrane Central Register of Controlled Trials (CENTRAL), World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov were searched through March 2015 using the phrases: "gonadotropin-releasing hormone," "chemotherapy," and "premature ovarian failure." Hand-search on conference abstracts, SCOPUS, and ISI Web of Science were also searched. METHODS OF STUDY SELECTION: Published English-language randomized controlled trials comparing resumption of ovarian function between GnRH analogs plus chemotherapy with chemotherapy without GnRH analogs were included. Studies including women with pelvic metastases or recent history of receiving chemotherapy were excluded. Accordingly, 10 eligible trials (907 women) were analyzed. TABULATION, INTEGRATION, AND RESULTS: Our primary outcome was the proportion of women with resumed ovarian function (defined as resumption of menstruation, prevention of chemotherapy-induced ovarian failure, or both) at the longest follow-up after the end of chemotherapy. Secondary outcomes were evaluating ovarian reserve parameters and pregnancy. Risk ratio was used to integrate qualitative results and mean difference was used for quantitative data. Gonadotropin-releasing hormone analog cotreatment did not significantly increase ovarian function resumption (320/468 [68.4%] in GnRH analog arm and 263/439 [59.9%] in the chemotherapy alone arm; risk ratio 1.12, 95% confidence interval [CI] 0.99-1.27). No protective effect existed after subgroup analyses (type of malignancy [P=.31], age [P=.14], and GnRH analog type [P=.44]). Gonadotropin-releasing hormone analogs did not protect any of ovarian reserve parameters, whether follicle-stimulating hormone (mean difference -2.63, 95% CI -7.33 to 2.07), antral follicle count (mean difference 1.66, 95% CI -0.69 to 4.01), or anti-Müllerian hormone (mean difference 0.31, 95% CI -0.41 to 1.03). Spontaneous pregnancy was also comparable (risk ratio 1.63, 95% CI 0.94-2.82). CONCLUSION: Gonadotropin-releasing hormone analog administration during chemotherapy does not appear to protect the ovaries from gonadal toxicity. It is not a reliable method for fertility preservation.
