RESUMO
Ovarian cancer is a known risk factor of venous thromboembolism (VTE). Thrombogenic factor expression and lymphocytic infiltrate have been reported in endometriosis and ovarian cancers. We reviewed 30 cases of ovarian carcinomas (high grade serous carcinoma, 10; endometrioid carcinoma, 10; clear cell carcinoma (CCC), 10) and 16 endometriotic lesions. We immunohistochemically investigated the expressions of tissue factor (TF), podoplanin, P-selectin, and number of CD4 and CD8 positive lymphocytes in cancer tissue and endometriotic lesions, along with their relationship with VTE. The expression of TF was higher in CCC. The TF expression and the number of CD8 positive cells were higher in cancer tissues with VTE than in those without VTE. The podoplanin or P-selectin expression did not differ among histological types or between cases with and without VTE. Our results demonstrated a high TF expression and intraepithelial CD8 cells in CCC, which were associated with VTE. The results suggest that infiltrating lymphocytes may affect TF expression that, in turn, influences VTE.

AIMS: Growth-restricted fetuses have delayed rhythm formation in utero. The awake-sleep cycle of fetal heart rate pattern is thought to represent fetal rhythm. We aimed to study if the emergence of rhythm formation on fetal heart rate pattern delays in fetal growth restriction compared to appropriate-for-date fetuses. METHODS: This was a retrospective cohort study including 75, normal-structured, singleton fetuses. Of them, 21 were fetal growth restriction and the remaining 54 were appropriate-for-date infants. We examined timing of emergence of rhythm formation on fetal heart rate pattern comparing between fetal growth restriction and appropriate-for-date fetuses after adjusting possible confounding factors as outcome measures. RESULTS: Rhythm formation was significantly delayed in fetal growth restriction (<10th percentile) compared to the appropriate-for-date subgroups (10-30, 30-50, 50-70 and 70-90th percentile) by 1-2 weeks. After adjusting confounding factors, growth restriction was the only independent variable to delay fetal rhythm formation. One infant for each group had neurodevelopmental disorder and the incidence did not reach statistically significant. CONCLUSION: Based on fetal heart rate pattern analysis, growth-restricted fetuses show 1-2 weeks delay in rhythm formation compared to appropriate-for-date fetuses.

AIMS: Magnesium sulfate has neuroprotective effects in preterm infants. Whether other antepartum treatments interfere with the neuroprotective actions is not well known. This study aims to explore the impacts of antenatal administration of Magnesium sulfate or beta-2 adrenergic agonists as tocolytic agents on the developing brain in premature infants. METHODS: This is a retrospective cohort study in four tertiary perinatal centers in Japan. We collected data of pregnant women and infants born between 28 and 36 weeks for tocolytic agents, gestational age, sex, antenatal corticosteroid, fetal growth restriction, pathological chorioamnionitis, low umbilical arterial pH values (<7.1), multiple pregnancy, mode of delivery and institutions after excluding clinical chorioamnionitis, non-reassuring fetal status or major anomalies. Tocolytic agents were categorized into four groups: no-tocolysis, magnesium sulfate, beta-2 adrenergic agonists and the combination of them. We conducted multiple comparisons with multivariate analyses using generalized linear regression models to compare the prevalence of a poor perinatal outcome defined as infant's death, brain damage, particularly cerebral palsy and developmental delay. RESULTS: Among 1083 infants, 39% were no-tocolysis, 47% were magnesium sulfate, 41% were beta-2 adrenergic agonists and 27% were combination group, including the duplication. The incidence of poor perinatal outcome was decreased by magnesium sulfate (OR 0.27, 95% CI 0.10-0.72), but not changed significantly by beta-2 adrenergic agonists (OR 1.28, 95% CI 0.63-2.59) or the combination group (OR 2.24, 95% CI 0.67-7.54), compared with the no-tocolysis. CONCLUSION: The combination therapy for tocolysis with beta-2 adrenergic agonists diminished the magnesium sulfate neuroprotective action after adjusting for covariables.

AIMS: Severe preterm fetal growth restriction (FGR) remote from term is problematic. We aimed to investigate the effect of maternally-administered antithrombin on maternal and neonatal outcomes. A prospective, one-arm, pilot study was performed in 14 women with severe FGR (≤5th centile) at <28 weeks of gestation, without hypertensive disorders. Maternal plasma concentrations of soluble Feline McDonough Sarcoma (FMS)-like trypsin kinase-1 (sFlt-1) and placental growth factor (PlGF) were measured and categorized into three groups: group 1; low sFlt-1 and high PlGF, group 2; moderate sFlt-1 and low PlGF, and group 3; high sFlt-1 and low PlGF. Antithrombin was administered for 3 days. The incidence of perinatal mortality, infant morbidity, and the period of pregnancy prolongation were compared. RESULTS: In group 1 (n=4), their pregnancies were extended for longer periods and the maternal and infant outcomes were good. The prolongation periods were shorter in groups 2 (n=3) and 3 (n=7), which resulted in poor maternal [severe preeclampsia or hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome] and infant outcomes. CONCLUSIONS: The evaluation of the maternal sFlt-1 and PlGF at 21-27 weeks of gestation is useful in the managements of severe FGR. Antithrombin treatment could prolong the pregnancies with low sFlt-1 and high PlGF without negatively affecting maternal or fetal health.

The developing fetus has some unique physiological properties that differ from properties in extra-uterine life. The fetus exists in a hypoxemic condition as a result of the presence of the placenta, which serves as a limiting interface between maternal and fetal circulation. In addition, the fetus is prone to be exposed to uterine contractions, which place it under a further hypoxic burden. Thus, the fetal response to hypoxic insults is important. There has been marked progression in the understanding of fetal physiology since the introduction of the 'chronic preparation model'. Based upon information from animal research, we now utilize medical technologies in daily medical care, for example, fetal heart rate monitoring and high-resolution ultrasonographic devices. In this review, we discuss the main findings in relation to fetal physiology and their clinical relevance.

We herein report a case of ovarian cancer recurrence detected every time with symptoms of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. A 46-year-old woman who had a history of ovarian cancer 9 months earlier developed joint pain along with pitting edema in both hands and was diagnosed with RS3PE syndrome. Two and four years after initial surgery for ovarian cancer, symptoms of RS3PE syndrome appeared, and a recurrent site was detected. With resection of the relapsed sites and increased maintenance dose of methylprednisolone, these symptoms improved within a month.

We report a case of delayed-interval delivery of a dichorionic, diamniotic twin pregnancy with the survival of both twins. The patient presented at 22 weeks and 1 day of gestation with vaginal bleeding and preterm labor. Five days later, the first twin was born. The second twin remained in utero. The management consisted of careful monitoring of both maternal and fetal status. Nine days later, the second twin was delivered vaginally. Both twins received full resuscitation and immediate life-support intervention; at 7 years of age both twins exhibited normal development.

Syphilis is an infectious disease caused by Treponema pallidum (T. pallidum). A cervical smear is useful when screening for sexually transmitted diseases; however, T. pallidum is not detected in the usual Papanicolaou smear. We report the detection of T. pallidum by immunocytological examination of a cervical smear. A 22-year-old woman presented with nephrotic syndrome. On admission, we performed screening tests for infections, and her serology was positive for syphilis. A Papanicolaou cervical smear (Thin-Prep) showed slight nuclear enlargement, nuclear irregularity, and mild hyperchromasia in the superficial cells, but no organism was detected. T. pallidum was detected in the remaining specimen using immunocytochemistry. We also detected the T. pallidum DNA in a cervical biopsy specimen by polymerase chain reaction (PCR). Our findings suggest that immunocytological examination and PCR assay examination are useful tests for syphilis diagnosis.

We experienced two rare cases of metastases to the central nervous system (cerebral and leptomeningeal metastases) from primary epithelial ovarian carcinoma. The first case was a 55-year-old woman who developed carcinomatous meningitis while on chemotherapy for ovarian cancer stage IIIC. Cytological analysis confirmed carcinomatous cells of ovarian origin in the cerebrospinal fluid. Magnetic resonance imaging demonstrated abnormal hyperintensity in the cerebral sulci on fluid attenuated inversion recovery (FLAIR) sequence with enhanced gadolinium indicating leptomeningeal metastases. Her consciousness rapidly declined and she died 42 days after diagnosis. The second case was a 63-year-old woman who underwent surgery for ovarian cancer and who was diagnosed as stage IA. Thirty-eight months after surgery, she developed weakness of the left hand and headaches. A CT scan revealed metastases to the right cerebrum and she was treated with surgical resection followed by radiotherapy. Five months after resection, she developed ileus caused by multiple relapses in the pelvis. Despite chemotherapy, her performance status declined and she died nine months after the resection. Both cases were rare because the first case was isolated leptomeningeal metastases, and the second case was confirmed relapse site in the cerebrum due to neurological symptoms despite her early clinical stage.
RESUMO
OBJECTIVE: Our purpose was to determine whether systolic arterial pressure, as predicted from the delay time from the electrocardiogram to pulse oximeter waveform, correlates with directly measured systolic blood pressure. METHODS: Six Japanese Saanen goats at 120-125 days' gestation were used. Experiments were conducted in acutely operated animals under anesthesia. We placed catheters in the carotid artery and jugular vein, electrodes on the chest, and a pulse oximeter probe on the tongue. Systolic blood pressure (Psm), fetal heart rate (FHR), delay time (Td), and pulse oximeter waveform were monitored continuously, and the data were stored. Systolic blood pressure was estimated (Pse) by the simple linear equation of Td. Fetal blood pressure was decreased 10% by hydralazine and blood withdrawal. Correlation coefficients and the agreement between Psm and Pse were determined. RESULTS: A significant correlation (P <.01) with good bias values (< 8 mmHg) and precision values (< 5 mmHg) was obtained between Psm and Pse in all animals. There was also a significant correlation between Psm and Pse with high coefficients for hydralazine (r(2) = 0.82 +/- 0.12) and for withdrawal (r(2) = 0.85 +/- 0.15). The correlations became slightly scattered in acidemia (pH < 7.25). CONCLUSIONS: This technique has the potential to provide information on fetal blood pressure during labor and delivery on a beat-by-beat basis, which will aid in the interpretation of electronic FHR recordings.

OBJECTIVES: We evaluated the efficacy of magnesium sulfate as a second-line tocolysis for 48 hours. MATERIALS AND METHODS: A multi-institutional, simple 2-arm randomized controlled trial was performed. Forty-five women at 22 to 34 weeks of gestation were eligible, whose ritodrine did not sufficiently inhibit uterine contractions. After excluding 12 women, 33 were randomly assigned to either magnesium alone or combination (ritodrine and magnesium). The treatment was determined as effective if the frequency of uterine contraction was reduced by 30% at 48 hours of the treatment. RESULTS: After magnesium sulfate infusion, 90% prolonged their pregnancy for >48 hours. Combination therapy was effective in 95% (18/19), which was significantly higher than 50% (7/14) for magnesium alone. CONCLUSION: This randomized trial revealed that combination therapy significantly reduced uterine contractions, suggesting that adjuvant magnesium with ritodrine is recommended, rather than changing into magnesium alone, when uterine contractions are intractable with ritodrine infusion.

OBJECTIVE: To report a case of successful orthotopic autotransplantation of fresh whole ovaries without vascular anastomosis. SETTING: Teaching hospital. PATIENT(S): A 34-year-old pregnant woman underwent emergency Cesarean hysterectomy during which both ovaries were accidentally removed. INTERVENTION(S): We performed fresh whole ovarian autotransplantation in the retroperitoneum, without vascular anastomosis. MAIN OUTCOME MEASURE(S): Serial hormonal measurement of E2, P4, LH, and FSH serum levels. RESULT(S): Follow-up during the 4.5 years since transplantation has shown that the patient's hormonal levels have remained functional. CONCLUSION(S): Our case reveals that the retroperitoneal cavity provides an effective vascular bed for ovarian grafts. This is the first report of orthotopic autotransplantation of fresh whole ovaries without vascular anastomosis.

The authors show that pulse transit time and blood pressure are reciprocal in fetal goat models. They applied this technique in clinical settings to correlate changes in pulse transit time with fetal heart rate monitoring patterns and acid-base status. In 18 uncomplicated pregnancies, pulse transit time was obtained from electrocardiograms to pulse oximeter waveform and averaged during each baseline period, defined by the interpretation of fetal heart rate monitoring. According to a > 10% change from the control value, chronological changes were categorized into shortened, unchanged, and prolonged. Pulse transit time was available in 82% +/- 11% of the recordings. In 15 fetuses, 2 (13%) showed prolonged, 7 (47%) showed shortened, and 6 (40%) showed unchanged conditions. Comparisons of the shortened and unchanged categories revealed that severe variable deceleration was significantly increased, and half or more fetuses showed hypoxemia in the shortened category. Shortening of pulse transit time, theoretically indicating a hypertensive condition, was more frequently associated with severe variable decelerations, suggesting that the pulse transit time may supplement the interpretation of fetal heart rate monitoring.
