Ethnic disparities in complete and partial molar pregnancy incidence: a retrospective analysis of arab and jewish women in single medical center.

BACKGROUND: Molar pregnancies, encompassing complete and partial moles, represent a rare and enigmatic gestational disorder with potential ethnic variations in incidence. This study aimed to investigate relations of ethnicity with risks of complete and partial molar pregnancies within an Israeli population while accounting for age differences. METHODS: A retrospective study was conducted of data recorded during 2007-2021 in an academic medical center in Israel. The study population comprised 167 women diagnosed with complete or partial moles, for whom data were obtained through histological examination and P57 immunostaining. Maternal age and ethnicity were extracted from electronic medical records. Incidence rates were calculated per 10,000 live births, and a nested case-control study compared demographic characteristics and molar pregnancy incidences between Arab and Jewish women. Statistical analyses included age-adjusted comparisons, relative risk calculations and multivariate logistic regression. RESULTS: The overall risk of molar pregnancy was 22 per 10,000 live births (95% confidence interval [CI] 18-25). Among Arab women, the overall risk was 21 (95% CI 17-25), and for PM and CM: 14 (95% CI 11-17) and 7 (95% CI 5-10), respectively. Among Jewish women, the overall risk was 23 (95% CI 18-29), and for PM and CM: 12 (95% CI 8-17) and 11 (95% CI 7-16), respectively. Among Arab women compared to Jewish women, the proportion of all the partial moles was higher: (65.3% vs. 51.6%, p = 0.05). The incidence of partial mole was higher among Arab than Jewish women, aged 35-39 years (26 vs. 8 per 10,000, p = 0.041), and did not differ in other age groups. After adjusting for age, the relative risk of partial moles was lower among Jews than Arabs (0.7, 95% CI 0.4-1.0, p = 0.053). For Arab compared to Jewish women, the mean age at molar pregnancies was younger: 31.0 vs. 35.1 years. However, other factors did not differ significantly between Arab and Jewish women with molar pregnancies. In multivariate analysis, Jewish ethnicity was significantly associated with a higher risk of complete molar pregnancies (OR = 2.19, 95% CI 1.09-4.41, p = 0.028). CONCLUSION: This study highlights ethnic differences in molar pregnancy risk within the Israeli population. Jewish ethnicity was associated with a higher risk of complete molar pregnancies, while Arab women had a significantly higher risk of partial moles. These findings underscore the need to consider ethnicity when studying gestational disorders. Further research should seek to elucidate the underlying factors contributing to these differences.

The accuracy of sonographic fetal weight in very preterm infants (≤32 weeks).

OBJECTIVE: To examine the accuracy of sonographic fetal weight to predict birthweight in very preterm infants (<32 weeks), and to compare the accuracy of estimated fetal weight (EFW) between those small for gestational age (SGA) and those appropriate for gestational age (AGA). STUDY DESIGN: A retrospective study was conducted of data recorded between January 2010 and March 2023. Included were women with singleton livebirths at 23+0-31+6 weeks who had an EFW within one week from delivery. Mean percentage error, mean absolute percentage error, and underestimation and overestimation rates were calculated. We compared the accuracy of EFW between SGA and AGA infants. RESULTS: In total, 360 women were included. The mean absolute percentage error was 7.8 % (range 0 %-68.9 %); for 207 (57.5 %) infants the percentage error was within ±10 %. Overestimation error >10 % was observed in 102 (28.3 %) infants and errors >20 % in 34 (9.4 %). Among infants born in the periviable period (23+0 - 25+6 weeks; N = 56), the mean absolute percentage error was 9.8 % (range: 0 %-40.3 %); the value was within ±10 % for only 28 periviable infants (50 %) and exceeded 20 % for 16.1 %. Among SGA compared to AGA infants, the mean absolute percentage error was higher (11.1% vs. 6.6 %, p = 0.035). Overestimation error >10 % was more frequent among SGA than AGA infants (55 (49.1 %) vs. 47 (19.0 %), p < 0.001). In a multivariate logistic regression analysis, SGA status was independently associated with a higher mean percentage error (beta = 0.260, p < 0.001) and an increased risk of an error >10 % (odds ratio = 2.1, 95 % confidence interval 1.2-3.5, p = 0.008). CONCLUSIONS: Sonographic EFW is limited in assessing very preterm infants, particularly those who are SGA or born during the periviable period. These limitations should be considered regarding impending very preterm births and concerns about abnormal fetal growth.

Detection and dissection of sentinel nodes in endometrial endometrioid cancer with indocyanine green using PinPoint laparoscopy: Analysis of the learning curve.

OBJECTIVE: Early-stage endometrial endometrioid adenocarcinoma is managed through laparoscopic total hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Detection of positive nodes is rare, and lymphadenectomy may involve complications. Pelvic sentinel lymph node dissection can prevent complete dissection. Herein, we evaluated the learning curve of sentinel lymph node dissection using indocyanine green. STUDY DESIGN: All surgeries for endometrial endometrioid adenocarcinoma were performed laparoscopically with indocyanine green to detect sentinel nodes. The primary outcome was the ability to identify and resect sentinel lymph nodes on each side. The secondary outcome was correspondence between the frozen section histology of the nodes with the final histology. RESULTS: Among 31 patients with endometrial endometrioid adenocarcinoma treated between October 2018 and August 2020, 29 who underwent laparoscopy using indocyanine green were enrolled. Complete lymphadenectomy was performed in 16 patients. Failure to recognize sentinel nodes on right and left sides occurred in 10.34% and 0% of cases, respectively. The median number of recognized and dissected sentinel nodes was 1 on both sides (range 0-5). One patient had a lymph node positive for malignancy on histology (3.45%) on both sides. There were 13 and 14 cases of negative frozen sections on the right and left sides, respectively, and 1 case of a positive frozen section with positive whole pelvic lymph nodes. CONCLUSION: Sentinel node dissection using indocyanine green in endometrial endometrioid adenocarcinoma has a distinct learning curve; however, it is practical and achievable for skilled surgeons.

The impact on pregnancy outcomes of late-onset gestational diabetes mellitus diagnosed during the third trimester: A systematic review and meta-analysis.

BACKGROUND: Evidence is inconsistent regarding the impact of late gestational diabetes mellitus (GDM) on perinatal outcomes. OBJECTIVES: To evaluate associations of GDM diagnosed in the third trimester (late GDM) with adverse obstetric and neonatal outcomes. SEARCH STRATEGY: We searched Embase, Medline, and Web of Science from January 1, 1990 to June 16, 2022, for observational studies. SELECTION CRITERIA: Late GDM was defined as a de novo diagnosis, i.e. after a negative screening for diabetes in the second trimester, and at later than 28 weeks of pregnancy. DATA COLLECTION AND ANALYSIS: Each abstract and full-text article was independently reviewed by the same two authors. Quality was assessed with the use of the Newcastle-Ottawa Scale. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a random effects model. MAIN RESULTS: Twelve studies were identified as meeting the inclusion criteria, including 3103 patients (571 with late GDM and 3103 controls). Incidences of shoulder dystocia (OR 1.57, 95% CI 1.02-2.42, P = 0.040), 5-minute Apgar score <7 (OR 1.80, 95% CI 1.14-2.86, P = 0.024), cesarean delivery (OR 1.98, 95% CI 1.51-2.60, P < 0.001), and emergent cesarean delivery (OR 1.57, 95% CI 1.02-2.40, P = 0.040) were significantly higher among women with late GDM than among the controls. The groups showed similarity in the rates of fetal macrosomia, large-for-gestational-age fetuses, neonatal hypoglycemia, and hypertensive disorders of pregnancy. CONCLUSIONS: This meta-analysis showed associations of late GDM with increased adverse perinatal outcomes. Prospective studies should evaluate the impact on perinatal outcomes of repeated third-trimester screening for late GDM.

A simplified two-marker immunohistochemistry strategy for Lynch syndrome screening in endometrial cancer patients.

OBJECTIVE: To examine the efficacy of MSH6 and PMS2 immunohistochemistry (IHC) as a screening method for Lynch syndrome in endometrial cancer patients. METHODS: Through multidisciplinary discussions, an institutional MSH6 and PMS2 IHC-initiated cascade test (MSH6, PMS2 IHC→microsatellite instability [MSI] assay→germline mismatch repair [MMR] gene sequencing) was developed to screen for Lynch syndrome in endometrial cancer patients. Testing was performed on a consecutive cohort of 218 newly diagnosed endometrial cancer patients who underwent surgery at a tertiary hospital in the Republic of Korea between August 2018 and December 2020. The number of MMR deficiencies (MSH6 or PMS2 loss in IHC) and. RESULTS: of subsequent tests (MSI assay and germline MMR gene sequencing) were examined. RESULTS: MMR deficiency was detected in 52 of the 218 patients (24.0%). Among these 52 patients, 34 (65.0%) underwent MSI testing, of which 31 (91.0%) exhibited high MSI. Of the 31 patients with MSI-high status, 15 (48.0%) underwent germline MMR gene sequencing. Subsequently, Lynch syndrome was diagnosed in five patients (33.0%). CONCLUSION: Lynch syndrome screening using MSH6 and PMS2 IHC-initiated cascade testing is a viable strategy in the management of endometrial cancer. A simplified strategy (MSH6 and PMS2 IHC→germline MMR gene sequencing) was proposed because most women with MMR deficiencies exhibited high MSI.

Clinical Implication of PD-L1 Expression in Patients with Endometrial Cancer.

This study investigated PD-L1 expression in endometrial cancer, its links with prognostic factors, and survival outcomes in 232 patients. Of these, 73 (31.5%) had PD-L1-positive tumors and 159 (68.5%) had PD-L1-negative tumors. PD-L1 expression significantly correlated with adverse prognostic factors. The PD-L1-positive group had higher rates of high-grade tumors (37.0% vs. 19.1%, p = 0.004), deep myometrial invasion (35.6% vs. 24.4%, p = 0.004), lymphovascular space invasion (LVSI) (39.7% vs. 25.6%, p = 0.023), and lymph node metastasis (7.2% vs. 17.1%, p = 0.024) than the PD-L1-negative group. While 5-year progression-free survival (PFS) favored the PD-L1-negative group (94.1% vs. 86.3%), this difference lacked statistical significance (p = 0.139). No significant variations emerged in overall survival (OS) (p = 0.596) or recurrence rates between the groups. Although outcomes lack statistical significance, they suggest a plausible link between PD-L1 and established adverse prognostic factors, such as histological grade, myometrial invasion depth, LVSI, and lymph node metastasis in endometrial cancer. These insights hint at PD-L1's potential as an informal prognostic indicator, potentially aiding in endometrial cancer patient management.

Nonelectric shaving of endometrial polyp by hysteroscopy - A new technique to eliminate thermal damage.

OBJECTIVE: To present a new technique for complete endometrial polypectomy, using the bipolar loop hysteroscope, but without the activation of electrical energy, and follow its efficiency and safety for the patient. STUDY DESIGN: This is a prospective descriptive study conducted at a university hospital. Forty four patients were recruited to the study according to an intra uterine polyp diagnosed by transvaginal ultrasound (TVS). Out of them 25 really had an endometrial polyp which was inspected by hysteroscopy. Eighteen were at menopause age and seven in their reproductive age. The hysteroscopic removal of the endometrial polyp was performed using the operative loop resectoscope without using electricity, meaning by cold loop. We called this unique technique SHEPH: Shaving of Endometrial Polyp by Hysteroscopy. RESULTS: The range age was 21-77 years old. All patients with apparently endometrial polyp, underwent a complete removal of the polyp which could be directly seen through hysteroscopy. No bleeding was seen in all cases. The other nineteen patients had normal uterine cavity, so a biopsy was taken according to the indication. The specimen from all cases were sent to histological evaluation. An endometrial polyp was histologically confirmed in all cases who underwent the SHEPH technique, while fragments of an endometrial polyp was revealed by histology in six cases from the group that had normal uterine cavity. No complications were noted for the short and long periods. CONCLUSIONS: Nonelectric Shaving of Endometrial Polyp by Hysteroscopy (SHEPH technique) is a safe and effective procedure which allows the surgeon to achieve a complete endometrial polypectomy but without using electrical energy within the body of the patient. The technique which is easy to learn, is new and unique by eliminate thermal damage in a very common gynecologic indication.

Risk factors and prediction of ectopic pregnancy rupture following methotrexate treatment: A retrospective cohort study.

OBJECTIVE: Ectopic pregnancy (EP) rupture after methotrexate (MTX) treatment can have severe consequences. We examined clinical characteristics and beta-hCG trends that may predict EP rupture after MTX treatment. STUDY DESIGN: In this 10-year retrospective study of 277 women with an EP, we compared clinical, sonographic and beta-hCG trends, before and after MTX treatment, between those who did and did not have an EP rupture after MTX treatment. RESULTS: EP rupture was diagnosed in 41 women (15.1%) within 25 days of MTX treatment, and was correlated with higher parity and advanced pregnancy age: 2(0-5) vs. 1(0-6), P = 0.027 and 6.6(4.2-9.8) vs. 6.1(4-9.5), P = 0.045. EP rupture was also correlated with higher beta-hCG levels on days 0, 4 and 7 of MTX treatment: (2063 vs. 920 mIU/ml), (3221 vs. 921 mIU/ml) and (2368 vs. 703 mIU/ml), respectively, P < 0.001, for all. An increase of beta-hCG by>14% during days 0-4 showed a sensitivity of 71.4% CI 95% [55.4%-84.3%] and a specificity of 67.5% CI 95% [61.1%-73.6%] for predicting EP rupture after MTX treatment. Beta-hCG > 910 mIU/ml on day 0 showed a sensitivity of 80.9% CI 95% [66.7%-90.8%] and a specificity of 70.4% CI 95% [64.1%-76.3%] for predicting EP rupture after MTX treatment. A beta-hCG increase by>14% during days 0-4, and a beta-hCG value > 910 mUI/mL on day 0 were associated with increased risks of EP rupture after MTX treatment; the odds ratios were 6.4 and 10.5, respectively. Odds ratios were 8.06 [CI 95% (3.70-17.56)], P < 0.001 for every percent rise in beta-hCG during days 0-4; 1.37 [CI 95% (1.06-1.86)], P = 0.046 for every week change in gestational age; and 1.001 [CI 95% (1.000-1.001)], P < 0.001 for every unit rise in beta-hCG at day 0. CONCLUSION: Beta-hCG > 910 mIU/ml at day 0, a rise in beta-hCG by>14% during days 0-4, and more advanced gestational age were associated with EP rupture after MTX treatment.

Alternative beta-hCG follow-up protocols after single-dose methotrexate therapy for ectopic pregnancy: A retrospective cohort study.

OBJECTIVE: This study assessed the relevance of reductions in beta-hCG levels between days 0 and 4 and between days 0 and 7 after single-dose methotrexate therapy, and the success of the therapy. STUDY DESIGN: A retrospective cohort study of 276 women diagnosed with ectopic pregnancy who received methotrexate as first-line treatment. Demographics, sonographic findings and beta-hCG levels and indexes were compared between women with successful and failed treatment outcomes. RESULTS: The median beta-hCG levels were lower in the success than the failure group on days 0, 4 and 7: 385 (26-9134) vs. 1381 (28-6475), 329 (5-6909) vs. 1680 (32-6496) and 232 (1-4876) vs. 1563 (33-6368), respectively, P < 0.001 for all. The best cut-off for the change in beta-hCG level from day 0 to 4 was a 19% decrease; the sensitivity was 77.0% and specificity 60.0%, positive predictive value (PPV) was 85% CI 95 [78.7.1%-89.9%]. The best cut-off for the change in beta-hCG level from day 0 to 7 was a 10% decrease; the sensitivity was 80.1% and specificity 70.8%, PPV was 90.5% CI 95 [85.1%-94.5%]. CONCLUSIONS: A decrease of 10% in beta-hCG between days 0 and 7 and 19% between days 0 and 4 can be used as a predictor of treatment success in specific cases.

The value of clinical symptoms, the neutrophil-to-lymphocyte ratio, and ultrasonographic features in predicting adnexal torsion: A case-control study.

AIM: Adnexal torsion remains a diagnostic challenge due to the nonspecific symptoms, sonographic features, and laboratory findings. The value of combining clinical, sonographic, and laboratory features is not well established, and controversy continues regarding their value in diagnosis. This study aimed to review sonographic, clinical, and laboratory features and to analyze their value separately and in combination, in managing and diagnosing adnexal torsions. METHODS: The study included 278 women who underwent urgent laparoscopic surgery due to suspected adnexal torsion, according to clinical suspicion, with or without sonographic concordance. Laparoscopy findings confirmed the definitive diagnosis of torsion. Clinical laboratory and sonographic features were compared between those with and without adnexal torsion. RESULTS: Adnexal torsion was confirmed in 110/278 (39.6%) women. In the torsion compared to nontorsion group, proportions were higher of women with acute abdominal pain in the preceding 24 h ([50] 45.5% vs. [35] 20.8%, p < 0.001), with vomiting ([45] 40.9% vs. [24] 14.3%, p < 0.001) and with suspected torsion by transvaginal sonography ([49] 44.5% vs. [23] 13.7%, p < 0.001). A high neutrophil-to-lymphocyte ratio (>3) was identified in 65 (59.1%) of the study group and 60 (35.7%) of the control group (p < 0.001). Combining the latter three findings, the predicted probability of torsion was 58%-85%, depending on the combinations. CONCLUSIONS: A simple predictive model based on combinations of clinical, laboratory, and sonographic findings can contribute to preoperative diagnosis of adnexal torsion, with predicted probability of 85%. Our model may assist clinicians in evaluating women with suspected adnexal torsion, and improve preoperative diagnostic accuracy.

The impact of the COVID-19 pandemic on ectopic pregnancy presentation and treatment: A retrospective cohort study.

OBJECTIVE: We examined ectopic pregnancy (EP) incidence, presentation and management, before and during the COVID-19 pandemic, and following initiation of vaccination against COVID-19. STUDY DESIGN: In a single-center retrospective cohort study, we compared incidence, presentation and management of EP, between 98 women who presented during the pandemic (March 1 2020 to August 31, 2021), and 94 women diagnosed earlier (March 1 2018 to August 31, 2019). Sub-periods before and after introduction of the vaccination were compared. RESULTS: Age and parity were similar between the periods. For the pandemic compared to the earlier period, the median gestational age at EP presentation was higher (6.24 ± 1.25 vs. 5.59 ± 1.24, P<0.001), and the proportions were higher of symptomatic women (42.9% vs. 27.7%, p = 0.035) and urgent laparoscopies (42.9% vs. 24.5%, p = 0.038). In a multivariable linear model, women who presented during the pandemic were more likely to undergo an urgent laparoscopy [OR 2.30, 95%CI (1.20-4.41)], P = 0.012. In urgent surgeries performed during the pandemic compared to the earlier period, the proportion of women with a hemoglobin drop >2 gr/dL was greater (60% vs. 30%, p = 0.024). Statistically significant differences were not found in sonographic or laboratory findings, in rupture or massive hemoperitoneum rates, or in the need for blood transfusion in urgent laparoscopy. Outcomes were similar before and after introduction of vaccinations. CONCLUSION: During the pandemic, and even after the introduction of vaccination, women with EP were more likely to undergo urgent surgery, and blood loss was greater. This is likely due to delayed diagnosis.

The value of a simple sonographic screening test for placenta accreta spectrum prediction: A case-control study.

BACKGROUND: Placenta accreta spectrum (PAS) represents life-threatening conditions; however, early diagnosis reduces complications and mortality rates. AIMS: To develop and evaluate the accuracy of a simple sonographic screening test for PAS prediction. MATERIALS AND METHODS: A retrospective case-control study of 481 women with singleton pregnancies at 28 weeks or later, with a scarred uterus or placenta praevia, who underwent sonographic testing for PAS detection during 2010-2020. We compared demographic and sonographic features, and delivery outcomes between women who were and were not confirmed to have a PAS condition at delivery. We evaluated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and predictive probability for the sonographic screening model. RESULTS: Among all the women with at least one sonographic sign (large lacunae or loss of clear zone), the odds ratio (OR) of PAS was 21.7 (95% CI, 16.7-70.4), among those with placenta praevia (and at least one sonographic sign), the OR was 41.9 (95% CI, 15.8-111). For the screening model (the combinations of placental location (major or minor placenta praevia) with at least one sonographic sign (large lacunae or loss of clear zone)), sensitivity, specificity, PPV, NPV and predicted probability were 94.9% (85.8-98.9%), 91.5% (88.4-93.9%), 60.9% (50.1-70.9%), 99.2% (97.7-99.8%) and 92.3%, respectively. CONCLUSIONS: A combination of simple ultrasound signs for PAS screening may be highly effective for prenatal assessment and prediction of placenta accreta. This screening test can be carried out as routine pregnancy follow-up for women with risk factors for PAS.

Changes in diagnostic sensitivity, incidence and presentation of complete and partial hydatidiform mole over the years.

OBJECTIVE: Molar pregnancy is the most common type of gestational trophoblastic disease. Several recent reports have described changes in the clinical representation, the incidence and the diagnostic sensitivity of molar pregnancy. These changes could be due to widespread use of transvaginal ultrasound and beta-hCG testing in the management of routine first-trimester investigations. STUDY DESIGN: This is a retrospective study of 144 women diagnosed with partial or complete mole at a regional medical center during 2007-2020. Incidence, demographics, clinical features and diagnostic sensitivity were compared between 2007 and 2014 and 2015-2020, and attempts were made to understand the bases of the changes between the time periods. RESULTS: Sixty-two moles were diagnosed during 2007-2014 and 82 during 2015-2020. The proportions of complete moles in the respective periods were 65% (40) and 18% (15). From the earlier to the later period, the incidence and proportion of complete moles decreased, and of partial moles, increased. The median gestational age at diagnosis of molar pregnancy was 9.3 weeks. In the later period, women presented less frequently with vaginal bleeding, though this remained the most common presenting symptom. The proportion of women who underwent surgical evacuation of the uterus due to suspected molar pregnancy decreased, as did the proportion of moles that was suspected in ultrasound evaluation (P < 0.001). CONCLUSION: The proportion of complete moles decreased between the periods examined. Gestational age at diagnosis was similar to data from 1994 to 2013. Some typical presenting symptoms of molar pregnancy decreased. However, earlier diagnosis of missed abortion can miss diagnoses of molar pregnancy.

Cerebroplacental ratio and neonatal outcome in low-risk pregnancies with reduced fetal movement: A prospective study.

Objective: To evaluate the effectiveness of the cerebroplacental ratio (CPR) in predicting poor outcomes in low-risk pregnancies with reduced fetal movements (RFMs). Study Design: This prospective study included singleton pregnancies at 28-40 weeks, presenting with RFM but no additional risk factors. Sub analysis was performed for pregnancies between 36 and 40 weeks. Umbilical artery (UA) and middle cerebral artery (MCA) pulsatility indices (PIs) were measured, and the MCA-PI to UA-PI ratio (CPR) was calculated. Mode of delivery, gestational age, fetal monitoring category, Apgar score at 1 and 5 min, birth weight, presence of meconium, umbilical artery pH, and neonatal intensive care unit (NICU) admission were recorded. Women with good and poor outcomes were compared with doppler indices and pregnancy characteristics. Results: Of 96 women, 86 had good outcomes. There was no significant difference in UA-PI (0.871 ± 0.171 vs. 0.815 ± 0.179, P = 0.446), MCA-PI (1.778 ± 0.343 vs. 1.685 ± 0.373, P = 0.309), or CPR (2.107 ± 0.635 vs. 2.09 ± 0.597, P = 0.993) between the poor and good outcome groups. No difference was found in the location of the placenta, biophysical profile (BPP) score, fetal sex, or amniotic fluid index (AFI) at the time of presentation. The proportion of nulliparous patients in the poor outcome group was higher than that of multiparous patients. Sub analysis for 36-40 weeks revealed the same results; no significant difference in UA-PI (0.840 ± 0.184 Vs 0.815 ± 0.195, P = 0.599), MCA-PI (1.724 ± 0.403 vs. 1.626 ± 0.382, P = 0.523), or CPR (2.14 ± 0.762 vs. 2.08 ± 0.655, P = 0.931) between poor and good outcome groups. Conclusions: CPR is not predictive of neonatal outcome in low-risk pregnancies with RFM. However, a higher proportion of poor outcomes in nulliparous women warrants further investigation.

Coexisting Epithelioid Trophoblastic Tumor and Placental Site Trophoblastic Tumor During Asymptomatic Relapse: A Case Report and Literature Review.

Gestational trophoblastic neoplasms are a group of trophoblastic tumors that include choriocarcinoma (CC), epithelioid trophoblastic tumors (ETTs), and placental site trophoblastic tumors (PSTTs). Mixed gestational trophoblastic neoplasms include combinations of CCs with ETTs and/or PSTTs; combinations of ETTs and PSTTs have also been described. This report describes the case of a 49-yr-old female with mixed ETT and PSTT discovered due to menstrual delay and a positive beta-human chorionic gonadotropin in serum 11 yr after normal pregnancy; it is an asymptomatic recurrence of the neoplasm after 2 yr. Moreover, only the ETT recurred without evidence of PSTT by biopsy and without any increase in human chorionic gonadotropin levels, even though human chorionic gonadotropin was positive in the first onset of the disease. We also reviewed published English literature, which revealed that there are only 36 cases of mixed trophoblastic tumors to date, of which pure mixed ETT and PSTT were reported only in four cases including our case. The most common combination is CC admixed with an ETT (52%), followed by CC with PSTT in 30.5%. CC admixed with an ETT and/or PSTT account for 83% of the cases, of which pure mixed ETT and PSTT were reported only in 4 cases (11%). The rarity of this condition entails reporting of all cases to facilitate future research and clinical management.

A possible association between hydatidiform mole and the COVID-19 pandemic: A retrospective cohort study.

OBJECTIVE: To confirm an increase in the number of women with molar pregnancy during the COVID-19 pandemic. METHODS: In this retrospective cohort study, all patients with complete or partial mole diagnosed at our institution between January 1, 2010 and October 31, 2020, were included. To verify whether there was an increase in the incidence of hydatidiform mole (HM) and deliveries in 2020, the incidences for each year from January 2010 to October 2020 were recorded. In addition, we identified all women who were diagnosed with HM from January to October 2020, and compared them with a control group who underwent uterine evacuation for missed abortion of a singleton pregnancy during the same period. We also documented the time taken to diagnose missed abortion or molar pregnancy to check if a delay in diagnosis can explain the increase in HM incidence. RESULTS: Between 2016 and 2019, there was a statistically significant increase in the incidence of molar pregnancy. A further increase occurred in 2020 (odds ratio = 2.071). The mean gestational age of the embryo at the time of diagnosis was smaller in the HM group than in the missed abortion group (6.3 ± 1.67-7.4 ± 2.4, one-sided P = 0.034), meaning that it took more time (days) to diagnose molar pregnancy than missed abortion (22.38 ± 10.32 vs. 15.83 ± 7.83 days, P = 0.012). CONCLUSION: There was a significant increase in the incidence of molar pregnancy during the COVID-19 pandemic, possibly because of the delay in receiving medical care. We recommend providing gynecological primary care services during a crisis, such as a pandemic.

The use of pre-caesarean prophylactic intra-arterial balloon catheters for suspected placenta accreta.

INTRODUCTION: The incidence of placenta accreta (PA) has markedly increased in the United States, from 1/30 000 in 1950 to 1/731 deliveries in 2011. Although placenta praevia after prior caesarean sections (CS) is the most important risk factor for PA, other risk factors make up 1-5% of PA occurrences. At our referral hospital, we use the pre-caesarean prophylactic balloon catheter with or without post-surgery embolisation in a hybrid room. Here, we evaluate the role of prior CS and placenta praevia on the outcome of this procedure. MATERIALS AND METHODS: This retrospective cohort analysis included 61 women during the years 2004-2016 with sonographic suspicion of PA who underwent balloon catheterisation prior to CS. RESULTS: Eleven women had no previous CS (18%). Mean previous CS rate was 1.85. Six women (9.8%) had previous dilatation and curettage (D&C); 36.4% of women with no previous CS had previous D&C compared with 4% of women with previous CS (P = 0.008). Placenta praevia was sonographically diagnosed in 55 women (90.2%). There was a higher rate of caesarean hysterectomy in women with previous CS than in those without (32% vs 0%, P = 0.052) but no significant difference in blood product requirements (45.5% vs 66%, P = 0.303). There was no significant difference in hysterectomy rate, blood transfusion or surgery duration between women with and without placenta praevia (P = 0.648, 0.594, 0.995, respectively). CONCLUSION: Previous CS rather than placenta praevia is a strong indicator of hysterectomy in cases of PA. Different risk factors for PA do not affect blood transfusion rates or surgery duration.
