Abnormal menstruation after radical trachelectomy and its effects on fertility.

AIM: To evaluate and identify the risk factors for abnormal menstruation after radical trachelectomy. METHODS: This study included 58 patients who underwent radical trachelectomy at our hospital between April 2005 and January 2018. Patients were divided into groups of those with no change in postoperative menstruation (regular [R] group; n = 46) and those with abnormal menstruation such as amenorrhea or hypomenorrhea (irregular [I] group; n = 12). The perioperative characteristics and fertility of the groups were compared retrospectively. The data were statistically analyzed using Student's t-test, Fisher's exact test and Mann-Whitney U test for univariate analysis and logistic regression analysis for multivariate analysis, with the level of statistical significance set at P < 0.05. RESULTS: Based on Federation of Gynecology and Obstetrics staging, 54 patients had stage IB1, 2 had stage IB2 and 2 had stage IIA1 cervical cancer. Eight patients received neoadjuvant chemotherapy. Pretreatment tumor size, residual uterine cavity length and neoadjuvant and postoperative chemotherapy use were not significantly different between the groups. Abnormal menstruation was significantly more common in patients with postoperative pelvic infection (R group, 13.0%; I group, 58.3%) and cervical stenosis (R group, 15.2%; I group, 58.3%). CONCLUSION: To maintain healthy menstruation even after radical trachelectomy, it is important to prevent postoperative pelvic infection and cervical stenosis.

Positive vaginal culture at rescue cerclage predicts subsequent preterm delivery.

PURPOSE: This retrospective case-control study is aimed to extract predictors of preterm delivery after rescue cerclage. MATERIALS AND METHODS: We collected the data from all the pregnant women who underwent rescue cerclage before 26+0 gestational weeks at our facility between July 2006 and July 2016. These women were divided into "delivery at <34 weeks" group (n = 12) and "delivery at ≥34 weeks" group (n = 12). Multiple factors that had been detected at the time of cerclage were compared between these two groups. RESULTS: "Gestational weeks at cerclage ≥23" and "positive vaginal culture at cerclage" were significantly more prevalent in the "delivery at <34 weeks" group than in the "delivery at ≥34 weeks" group. "Prolapsed membranes at cerclage" tended to be more prevalent in the "delivery at <34 weeks" group than in the "delivery at ≥34 weeks" group. "Positive vaginal culture at cerclage" was the only independent risk factor associated with eventual preterm delivery before 34 gestational weeks. CONCLUSIONS: Simple aerobic bacterial culture of the vaginal swab sampled at the time of cerclage could be used as a reliable test to predict subsequent preterm delivery before 34 gestational weeks.

Introduction of management protocol for early-onset severe pre-eclampsia.

AIM: This quality Improvement study evaluated the applicability of our protocol for early-onset severe pre-eclampsia, prepared in April 2013. METHODS: We collected data from all women with early-onset severe pre-eclampsia treated at our hospital between March 2008 and August 2015. Neonatal and maternal outcomes were compared between protocol-based (n = 17) and non-protocol-based management groups (n = 28). RESULTS: The latency period was significantly longer in the protocol-based than in the non-protocol-based group (21.9 ± 3.7 vs 11.0 ± 2.9 days). Gestational age at delivery was significantly more advanced in the protocol-based than in the non-protocol-based group (31.4 ± 0.6 vs 29.8 ± 0.4 weeks). Serious neonatal complications were significantly less prevalent in the protocol-based than in the non-protocol-based group (26% vs 79%). Among the protocol components, magnesium sulfate use was the only independent factor contributing to the absence of serious neonatal complications. The percentages of women exhibiting persistent proteinuria or hypertension at one, two and three months post-partum were similar between the groups. CONCLUSIONS: Strict adherence to our protocol improved neonatal outcomes without affecting maternal prognosis. Routine use of magnesium sulfate could be the most important component of the protocol.

Planned vaginal delivery versus planned cesarean delivery in cases of low-lying placenta.

OBJECTIVE: To assess the applicability of trial of labor in cases of low-lying placenta. METHODS: In this observational cohort study, we collected data from the women with low-lying placenta delivered at our hospital between April 2012 and December 2015. Low-lying placenta was diagnosed when the length from the placental lowest edge to the internal cervical os (placenta-os distance) was 0-20 mm at 36 gestational weeks. Planned mode of delivery for each case was determined by patient's preference. Maternal and neonatal outcomes were compared between the planned vaginal delivery group (N = 11) and the planned cesarean delivery group (N = 7). RESULTS: All the women in the planned cesarean delivery group underwent scheduled cesarean section at 37-38 gestational weeks. Three cases in the planned vaginal delivery group required emergency cesarean section for uncontrollable antepartum bleeding. The intrapartum blood loss was significantly smaller in the planned vaginal delivery group than in the planned cesarean delivery group (946 ± 204 g vs. 1649 ± 256 g, p = 0.047). Umbilical arterial blood pH was similar between the two groups. All the women requiring emergency cesarean section were accompanied by marginal sinus. CONCLUSIONS: Trial of labor can be offered to all the women with low-lying placenta except for those accompanied by marginal sinus.

[Dysfibrinogenemia developed in a pregnant woman who has fibrinogen AαThr312Ala (ACT/GCT) polymorphism].

Blood coagulation factors play an essential role in pregnancy. We describe a 30-year-old pregnant woman whose course was complicated by dysfibrinogenemia with polymorphism of fibrinogen AαThr312Ala (rs6050) GG genotype. She was admitted to our hospital for genital bleeding and a huge subchorionic hematoma at 6 gestational weeks. Her first pregnancy and delivery had been uneventful, whereas her second and third pregnancies had resulted in spontaneous abortions with massive subchorionic hematomas. Her fibrinogen activity level was 125 mg/dl and this was lower than her fibrinogen antigen level. We administered tranexamic acid early in the pregnancy, and the subchorionic hematoma diminished in size in accordance with the increase of her fibrinogen level. At 16 gestational weeks, her D-dimer levels were elevated, and heparin treatment was initiated as an alternative. A male infant was delivered at 36 gestational weeks. Intrapartum hemorrhage was 600 g. Patients with coagulation abnormalities are often asymptomatic in the absence of pregnancy. However, when they become pregnant, the spontaneous abortion rate is high. Careful observation and effective management of coagulation abnormalities are essential for such patients to carry their pregnancies to term.

Immunoglobulin G4-related disease presenting as bilateral ovarian masses and mimicking advanced ovarian cancer.

Immunoglobulin G4-related disease (IgG4-RD) is characterized by extensive infiltration of IgG4(+) plasma cells and fibrosis in various organs. However, the involvement of the ovary in IgG4-RD has never been reported. A 59-year-old woman presented with urinary retention. Magnetic resonance imaging and computed tomography revealed a huge multinodular pelvic mass and common iliac/para-aortic lymph node swelling. A laparotomy was performed under the suspicion of advanced ovarian cancer, and the pelvic mass was identified as ovary in origin. Histopathology of the excised tumor revealed massive lymphoplasmacytic infiltration (>90% were IgG4(+) plasma cells), storiform fibrosis, and obliterative phlebitis; thus leading to a diagnosis of IgG4-RD. We conclude that IgG4-RD can present as a bilateral ovarian mass along with lymphadenopathy, therefore mimicking ovarian cancer.

Twin vaginal delivery is associated with lower umbilical arterial blood pH of the second twin and less intrapartum blood loss.

OBJECTIVE: To clarify actual differences in the neonatal as well as maternal outcome between completed twin vaginal delivery and cesarean delivery. METHODS: We collected the data from women with a twin pregnancy who delivered two live fetuses between 1 January and 31 December 2014 at 20 teaching hospitals (1) (1) PARTICIPANTS: Adachi Hospital, Hyogo Prefectural Amagasaki General Medical Center, Japan Baptist Hospital, Kitano Hospital, Kobe City Medical Center General Hospital, Kosaka Women's Hospital, Kurashiki Central Hospital, Kyoto University Hospital, Mitsubishi Kyoto Hospital, Nagahama Red Cross Hospital, National Hospital Organization Kyoto Medical Center, National Hospital Organization Osaka National Hospital, Osaka Red Cross Hospital, Otsu Municipal Hospital, Otsu Red Cross Hospital, Red Cross Wakayama Medical Center, Saiseikai Noe Hospital, Shizuoka General Hospital, Takamatsu Red Cross Hospital and Tenri Hospital. in Japan. Only the cases that were retrospectively regarded as eligible for planned vaginal delivery were analyzed according to the actual mode of delivery. RESULTS: Umbilical arterial blood pH (UmA-pH) of the second twin was slightly but significantly lower in the vaginal delivery group (7.26 ± 0.009) than in a cesarean delivery group (7.30 ± 0.006). Vaginal delivery was the only independent risk factor for second twin's UmA-pH <7.20. Intrapartum blood loss was significantly larger in the cesarean delivery group (1444 ± 63 g) than in the vaginal delivery group (820 ± 109 g). Cesarean delivery was an independent risk factor for intrapartum blood loss ≥1500 g. CONCLUSION: Twin vaginal deliveries were associated with slightly but significantly lower UmA-pH of the second twin, whereas twin cesarean delivery was associated with significantly larger intrapartum blood loss. Not only the neonatal risk but also the maternal risk should be taken into account when an optimal delivery mode for the twin pregnancy is considered.

Transverse fundal uterine incision for delivery of extremely low birth-weight infants.

Caesarean section of extremely low birth-weight (ELBW) infants is sometimes challenging for obstetricians. To date, there have been no standard types of uterine incision to achieve an atraumatic birth for ELBW fetuses with the placenta covering the whole anterior uterine wall. We present seven cases of transverse fundal uterine incision to avoid incision into the placenta. All the seven cases had successful en caul deliveries (the mean birth weight, 619 ± 213 g), accompanied by good neonatal conditions. Transverse fundal uterine incision may be a safe and feasible caesarean technique in ELBW infants when incision into the placenta is otherwise unavoidable.
