The aim of this study was to evaluate the surgical impact of benign ovarian mass on ovarian reserve as measured by serum follicle stimulating hormone (FSH), estradiol (E2) and anti-Müllerian hormone (AMH) levels, antral follicle count (AFC) and ovarian volumes. In addition, the differences in ovarian reserve impairment between endometrioma cystectomy and non-endometrioma cystectomy were investigated. In this prospective study, 22 patients of reproductive age (range, 18.35 years) with benign ovarian masses were enrolled to undergo laparoscopic cystectomy. Of whom 12 had endometriomas and 10 had non-endometriomas. On early follicular phase (day 3) of the cycle preceding the operation and three months after the laparoscopic cystectomy, serum levels of FSH, E2 and AMH, AFC and ovarian volumes were measured in all patients. Data were analyzed with Mann-Whitney U-test and Wilcoxon rank test using SPSS ver. 12.0 for statistic analysis. Median level of serum AMH was significantly decreased from 5.48 ng/mL (interquartile range [IQR], 2.80-7.47) before cystectomy to 2.56 ng/mL (IQR, 1.74-4.32) 3 months postoperation (P<0.05). On the other hand, no significant differences in FSH, E2, AFC and ovarian volumes were found between the preoperative and three months postoperative levels. In a subgroup analysis of the pathologic type of the ovarian cyst, postoperative serum AMH levels were significantly decreased in the endometrioma group, but not in the non-endometrioma group. Serum AMH levels were significantly decreased after laparoscopic cystectomy without any changes of other ovarian reserve tests.

There are reports that pregnant women infected with SARS-CoV-2 not only have increased morbidity but also increased complications and evidence of maternal and fetal vascular malperfusion on placental pathology. This was a retrospective study of pregnant women diagnosed with SARS-CoV-2 infection after March 2020. The results of reverse transcription polymerase chain reaction testing and IgM and IgG antibody testing of the amniotic fluid, cord blood, placenta, and maternal blood were confirmed at delivery. Placentas were evaluated histopathologically. The study included seven pregnant women diagnosed with SARS-CoV-2 infection during pregnancy at a mean gestational age of 14.5 weeks. Out of the seven women, five were infected during the first trimester. The mean gestational age at delivery was 38.4 weeks. The reverse transcription polymerase chain reaction results for maternal plasma, cord blood, placenta, and amniotic fluid were negative and IgG antibodies were detected in maternal plasma and cord blood. On placental pathology, maternal vascular malperfusion was found in only one case, fetal vascular malperfusion in four cases, and inflammatory changes were found in two cases. Pregnancy outcomes for women diagnosed with SARS-CoV-2 infection during early pregnancy are positive and it is likely that maternal antibodies are passed to the fetus, which results in a period of immunity.

Objectives To establish whether a correlation exists between the fetal middle cerebral artery peak systolic velocity (MCA PSV) and fetal hemoglobin levels before intrauterine transfusion (IUT) in cases of severe fetal anemia. Methods This was a single-center, retrospective study of data from 49 fetuses treated with IUT for fetal anemia between 2003 and 2018. Severe fetal anemia was suspected when MCA PSV was or exceeded 1.55 multiples of the median. Results The causes of anemia were largely idiopathic, and the overall survival rate was 57%. MCA PSV and hemoglobin were correlated in all 34 fetuses with alloimmune fetal anemia, whereas the 15 fetuses with nonimmune causes showed no correlation. Of the 15 noncorrelated cases, twin pregnancy was most common, followed by idiopathic causes. All the twin pregnancies involved monochorionic twins. Fetal hydrops, especially ascites, was significantly associated with severe anemia. Conclusions Fetal MCA PSV may not be a reliable independent factor for the diagnosis of severe fetal anemia in nonimmune cases, and the presence of associated hydrops implies that the fetus is more likely to have severe fetal anemia than in a fetus without hydrops.

Antimicrobial resistance is currently becoming a global threat to human health. We performed a retrospective study on patients who underwent emergency cerclage between January 2016 and December 2018 at the Dongsan Medical Center. Cervical culture was first performed before surgery to confirm that there was no infection and was repeated on days 1, 4, and 7 after surgery. A total of 85 pregnant women underwent emergency cerclage. Among them, six patients had vancomycin-resistant enterococci (VRE) colonization in the cervix after cerclage, and 23 patients developed extended-spectrum β-lactamase (ESBL)-producing bacterial colonization in the cervix. The average gestational age at delivery was lower in the VRE group. Neonatal death was also significantly higher in the VRE group. The rate of occurrence of early-onset sepsis was also higher in the VRE group, and both VRE and ESBL-producing bacterial colonization cases in which early-onset sepsis occurred resulted in neonatal death. The prognosis of cervical VRE colonization after cervical surgery was poor, whereas the prognosis of ESBL-producing bacterial colonization in the cervix did not differ significantly from that of the control group. However, careful neonatal treatment is required considering that early-onset sepsis is fatal to the newborn.
