Risk Factors and Pregnancy Outcomes of Antepartum Hemorrhage in Women with Placenta Previa.

Placenta previa (PP) is one such complication related to several adverse pregnancy outcomes. Adverse outcomes are likely greater if PP coexists with antepartum hemorrhage (APH). This study aims to evaluate the risk factors and pregnancy outcomes of APH in women with PP. This retrospective case-control study included 125 singleton pregnancies with PP who delivered between 2017 and 2019. Women with PP were divided into two groups: PP without APH (n = 59) and PP with APH (n = 66). We investigated the risk factors associated with APH and compared the differences between both groups in placental histopathology lesions due to APH and the resulting maternal and neonatal outcomes. Women with APH had more frequent antepartum uterine contractions (33.3% vs. 10.2%, P = .002) and short cervical length (< 2.5 cm) at admission (53.0% vs. 27.1%, P = .003). The placentas from the APH group had lower weight (442.9 ± 110.1 vs. 488.3 ± 117.7 g, P = .03) in the gross findings, and a higher rate of villous agglutination lesions (42.4% vs. 22.0%, P = .01) in the histopathologic findings. Women with APH in PP had higher rates of composite adverse pregnancy outcomes (83.3% vs. 49.2%, P = .0001). Neonates born to women with APH in PP had worse neonatal outcomes (59.1% vs. 23.9%, P = .0001). Preterm uterine contractions and short cervical length were the most significant risk factors for APH in PP.

Frequency of serous tubal intraepithelial carcinoma (STIC) in patients with high grade serous ovarian cancer.

OBJECTIVE: Serous tubal intraepithelial carcinoma (STIC) is a known precursor of high-grade serous ovarian cancer (HGSOC). This study aimed to evaluate the proportion of STIC in patients with HGSOC and analyze the STIC-related prognosis in patients with HGSOC. MATERIALS AND METHODS: All pathology reports at our institution that included bilateral salpingectomies of patients with HGSOC from January 2013 to December 2018 were reviewed by two experienced pathologists. The specimens from the ovaries and the salpinx including fimbria were examined. We analyzed the correlation between STIC and HGSOC and compared the clinical characteristics and STIC-related prognostic outcomes in patients with HGSOC. RESULTS: Eleven of the 76 cases were STIC. BRCA mutations were found in 16.9% of patients with HGSOC. STIC was observed in 30.0% of patients with BRCA mutations and in 14.3% of patients without BRCA mutations. The incidence of STIC in patients with BRCA mutations was approximately twice that in patients without BRCA mutations; however, the difference was not statistically significant (P = 0.231). Further, the 5-year survival rate of patients without STIC appeared to be high; nevertheless, the difference was not statistically significant (59.7% vs. 47.4%, P = 0.633). Moreover, there was no significant difference in disease-free survival rate according to STIC (36.4% vs. 33.1%, P = 0.956). CONCLUSION: STIC was identified in patients with HGSOC, and STIC incidence was prominent in HGSOC related to BRCA mutation. Although low frequency, STIC was detected in patients without BRCA mutation. Therefore, prophylactic salpingectomy may be useful for prevention of HGSOC.

Neonatal outcomes between discordant monochorionic and dichorionic twins.

OBJECTIVES: This study aimed to compare obstetrical complications and neonatal outcomes between monochorionic and dichorionic discordant twin pregnancies. STUDY DESIGN: We enrolled 296 patients with twin pregnancy who delivered at Busan Paik Hospital between January 2014 and December 2017. The prevalence of obstetrical complications, neonatal mortality between monochorionic and dichorionic twins was compared. We also investigated whether there is a difference in neonatal outcome and neonatal morbidity between monochorionic discordant twins without monochorionic-specific complications and dichorionic discordant twins. RESULTS: The risk of fetal death in utero (13.2 versus 5.2%, p = .025) and inter twin birth weight discordance (35.1 versus 20.8%, p = .031) is increased in monochorionic twins than in dichorionic twins. However, no difference was noted in obstetrical complication and neonatal mortality and morbidity between two groups. Among twin pregnancies with intertwin birth weight discordance, after excluding fetal death in utero and monochorionic specific complication, there was no difference in obstetrical complication and neonatal mortality and morbidity according to chorionicity. There was no difference in neonatal morbidity between monochorionic twins and dichorionic twins when comparing larger neonates and smaller neonates of each group. CONCLUSIONS: Risk of birth weight discordance is higher in monochorionic twin but no significant difference was observed in maternal outcomes, neonatal mortality and morbidity between noncomplicated monochorionic and dichorionic discordant twins.

Female with 46, XY karyotype.

Disorders of sex development (DSD) are congenital conditions characterized by atypical development of chromosomal, gonadal, and phenotypic sex. 46, XY DSD can result from disorders of testicular development or disorders of androgen synthesis/action. Prophylactic gonadectomy should be considered in patients with 46, XY DSD because of the increased risk of gonadal malignancy. We report two rare cases of 46, XY DSD, including XY pure gonadal dysgenesis and complete androgen insensitivity syndrome, who underwent a prophylactic gonadectomy.
