Meta-Analysis
INTRODUCTION
The levonorgestrel oral emergency contraceptive is well tolerated and effective, however its use is still limited, mainly due to safety concerns.
OBJECTIVE
This systematic review and meta-analysis aimed to summarize current evidence regarding the adverse events, and their prevalence, reported during the use of oral levonorgestrel emergency contraceptives.
METHODS
Four electronic databases and the US FDA Adverse Event Reporting System (FAERS) Public Dashboard were searched. Studies that reported or investigated safety outcomes or adverse reactions during the use of levonorgestrel as an emergency oral contraceptive were included. Data on study design, demographics of levonorgestrel and the control cohort, and reported adverse effects were extracted.
RESULTS
A total of 47 articles were included in this systematic review, from which it was shown that most of the adverse reactions were common and not serious. Uncommon adverse reactions identified included anorexia, ectopic pregnancy, exanthema, chloasma, miscarriage, and weight gain. Multiple serious adverse events, including convulsion, ectopic pregnancy, febrile neutropenia, stroke, abdominal hernia, anaphylaxis, cancer, ovarian cyst rupture, serious infections, and suicidal ideation, were reported. In addition, the prevalence of adverse events after a levonorgestrel 0.75 mg two-dose regimen and a levonorgestrel 1.5 mg single-dose regimen were not statistically different (p > 0.05).
CONCLUSIONS
The most common adverse effects of levonorgestrel were not serious. This systematic review shows that data regarding the adverse reactions of repeated use of levonorgestrel are scarce. Studies on the multiple uses of levonorgestrel emergency contraception are still required to ensure its safety.

Meta-Analysis
OBJECTIVE
To examine the effects of intraoperative ovarian capsule rupture on progression-free survival and overall survival in women who are undergoing surgery for early-stage ovarian cancer.
DATA SOURCES
MEDLINE using PubMed, EMBASE (Elsevier), ClinicalTrials.gov, and Scopus (Elsevier) were searched from inception until August 11, 2020.
METHODS OF STUDY SELECTION
High-quality studies reporting survival outcomes comparing ovarian capsule rupture to no capsule rupture among patients with early-stage epithelial ovarian cancer who underwent surgical management were abstracted. Study quality was assessed with the Newcastle-Ottawa Scale, and studies with scores of at least 7 points were included.
TABULATION, INTEGRATION, AND RESULTS
The data were extracted independently by multiple observers. Random-effects models were used to pool associations and to analyze the association between ovarian capsule rupture and oncologic outcomes. Seventeen studies met all the criteria for inclusion in the meta-analysis. Twelve thousand seven hundred fifty-six (62.6%) patients did not have capsule rupture and had disease confined to the ovary on final pathology; 5,532 (33.7%) patients had intraoperative capsule rupture of an otherwise early-stage ovarian cancer. Patients with intraoperative capsule rupture had worse progression-free survival (hazard ratio [HR] 1.92, 95% CI 1.34-2.76, P<.001), with moderate heterogeneity (I2=41%, P=.07) when compared with those without capsule rupture. Pooled results from these studies showed a worse overall survival (HR 1.48, 95% CI 1.15-1.91, P=.003), with moderate heterogeneity (I2=53%, P=.02) when compared with patients without intraoperative capsule rupture. This remained significant in a series of sensitivity analyses.
CONCLUSION
This systematic review and meta-analysis of high-quality observational studies shows that intraoperative ovarian capsule rupture results in decreased progression-free survival and overall survival in women with early-stage ovarian cancer who are undergoing initial surgical management.

Meta-Analysis Review
OBJECTIVE
To review short- and long-term complications associated with intraoperative rupture of benign ovarian cysts.
DATA SOURCES
The Cochrane Central Register of Controlled Trials, BIOSIS, Medline (Ovid), Web of Science, ClinicalTrials.gov, and Google Scholar were searched using the following terms and their combinations: "spillage," "rupture," "leakage," "ovarian cyst," "teratoma," "dermoid," "operative," "surgery," "outcome."
METHODS OF STUDY SELECTION
Randomized controlled and observational studies evaluating the operative outcomes of surgical treatment of ovarian cysts with intraoperative spillage compared with those of surgical treatment of ovarian cysts without spillage were included. A systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed.
TABULATION, INTEGRATION, AND RESULTS
A total of 28 studies were included in the qualitative analysis and 12 in the quantitative analysis. Ovarian cyst diameter was not found to be associated with the risk for spillage (relative risk [RR] 0.75; 95% confidence interval [CI], -0.33 to 1.82). Intraoperative benign ovarian cyst rupture was not associated with adverse short- and long-term outcomes such as reoperation (RR 1.16; 95% CI, 0.39-3.48), infertility (RR 0.73; 95% CI, 0.15-3.63), transient fever (RR 3.22; 95% CI, 0.83-12.51), and readmission (RR 1.00; 95% CI, 0.33-2.98). However, intraoperative spillage was found to be associated with increased risk for benign recurrence (RR 3.1; 95% CI, 1.05-9.14). A subgroup analysis of the studies that included only dermoid cysts showed an association between intraoperative cyst rupture and postoperative chemical peritonitis (RR 9.36; 95% CI, 1.20-73.28).
CONCLUSION
Intraoperative ovarian cyst spillage of a benign cyst is associated with limited adverse clinical outcomes. Although the surgical approach (minimally invasive vs open) should not be affected by the concern regarding an intraoperative cyst rupture, maximal efforts should be made to prevent intra-abdominal spillage.

Review
INTRODUCTION
Extragonadal teratomas (EGTs) are rare and the commonest intra-abdominal subtype is omental. We present two cases: 1) a parasitic omental teratoma likely secondary to auto-amputation of an ovarian teratoma with subsequent omental reimplantation and 2) an omental immature teratoma likely due to parthenogenetic activation of displaced primordial germ cells. We subsequently conduct a systematic review to characterise EGTs.
METHODS
We sourced for English, peer-reviewed case reports of extragonadal teratomas in women and female adolescents aged 11 and above published from inception of each database through 31st June 2020 following PRISMA guidelines. Two authors reviewed each case for appropriateness and each case was graded for methodological quality utilising a modified Newcastle Ottawa Scale. PROSPERO Registration Number: CRD42020190131 RESULTS: Upon literature review between 1920-2020, from an initial screen of 818 articles, 67 articles were selected featuring 70 cases. One case featured an immature teratoma while the remaining were mature. Omental EGTs were the most common (56.5 %) followed by Pouch of Douglas and uterosacral ligament (23.2 %) and upper abdomen (14.5 %). There were statistically significant differences in EGT mean sizes between each location with the largest being in the upper abdomen (10.9 cm) and the smallest being in the adnexa or hernia (6.2 cm). Auto-amputation was deemed the commonest cause amongst omental EGTs (55.3 %) and Pouch of Douglas and uterosacral ligament EGTs (37.5 %) while 70 % of upper abdominal EGTs were likely due to displaced primordial germ cells. We characterise clinical features associated with each pathogenic mechanism and imaging characteristics of EGTs. Characterisation of EGT tumour marker profiles was limited as only 42.9 % of cases reported them but 19.2-25.0 % had raised tumour markers. The main risks are torsion, rupture, immature components and potential malignant change of the cell lines. Treatment is largely surgical. The mean size of EGTs approached laparoscopically and via laparotomy was 5.23 cm and 9.16 cm respectively.
CONCLUSIONS
While rare, EGTs should be considered when evaluating pelviabdominal masses with imaging characteristics consistent with teratomas. Confirmation is usually intraoperative and a laparoscopic approach is reasonable if there is good surgeon comfort and the size is about 5 cm.

Meta-Analysis Review
Few studies investigated the efficacy and safety of minimally invasive surgery for the treatment of early-stage epithelial ovarian cancer (eEOC). In this context, we aimed to review the current evidence comparing laparoscopy and the laparotomic approach for staging procedures in eEOC. This systematic review was registered in the International Prospective Register of Systematic Reviews. Overall, 3065 patients were included: 1450 undergoing laparoscopy and 1615 undergoing laparotomic staging. Patients undergoing laparoscopy experienced a longer (but not statistically significant) operative time (weighted mean difference [WMD] = 28.3 minutes; 95% confidence interval [CI], -2.59 to 59.2), a lower estimated blood loss (WMD = -156.5 mL; 95% CI, -216.4 to -96.5), a shorter length of hospital stay (WMD = -3.7 days; 95% CI, -5.2 to -2.1), and a lower postoperative complication rate (odds ratio [OR] = 0.48; 95% CI, 0.29-0.81) than patients undergoing laparotomy. The upstaging (OR = 0.81; 95% CI, 0.55-1.20) and cyst rupture (OR = 1.32; 95% CI, 0.52-3.38) rates were similar between groups. Laparoscopic staging is associated with a shorter time to chemotherapy than laparotomic procedures (WMD = -5.16 days; 95% CI, -8.68 to -1.64). Survival outcomes were not influenced by the route of surgery. Pooled data suggested that the minimally invasive surgical approach is equivalent to laparotomy for the treatment of eEOC and may be superior in terms of perioperative outcomes. However, because of the low level of evidence of the included studies, further randomized trials are warranted.

Review
Although cancer diagnosed during pregnancy is rare, epithelial cell type ovarian cancers (EOCs) comprise approximately one quarter to one half of cases of ovarian malignancy diagnosed during pregnancy. The behavior of EOC during pregnancy and its implications for maternal and fetal outcomes is not well understood. In order to better define these outcomes, a systematic literature search was conducted in PubMed/MEDLINE using entry keywords "pregnancy" and "ovarian cancer" for the period from 1955 to 2013. The literature search identified 105 cases eligible for analysis. Clinical characteristics, pregnancy outcome, tumor characteristics, clinical management, and survival outcomes were all evaluated. Serious adverse events were defined as complications related to EOC that resulted in severe morbidity or mortality for the mother and/or fetus. The mean age of cases was 31.6 years. The most common histology was serous (47.6%), followed by mucinous (27.6%) and endometrioid types (10.5%). The most common presenting symptom was abdominal or pelvic pain (26.7%) while incidentally detected tumors accounted for one third of cases. The majority of cases were stage I at diagnosis (63.8%) followed by stage III disease (24.8%), and the median tumor size was 12cm. Live births occurred in 81.3% of cases, and of the remainder 72.2% were due to elective termination. Intrapartum surgery primarily took place in the second trimester (43%) with fetal conservation in 61.9% of operations. Over half of cases received chemotherapy (55.2%), approximately one third of which received it during the pregnancy (36.2%). Among the 21 cases treated with chemotherapy during pregnancy, there was no association with small for gestational age or fetal malformations. Serious adverse events occurred in 21.9% of cases, of which the most common was tumor rupture during pregnancy (10.5%). Three (2.9%) maternal death following surgery during pregnancy and five (6.4%) neonatal deaths were reported. Gestational age at tumor diagnosis (2-year overall survival rate, 1st trimester 94.6%, 2nd trimester 88.8%, and 3rd trimester 72.9%, p=0.041) type of histology (serous 88.1%, mucinous 84.6%, endometrioid 89.5%, clear cell 100%, mixed type 75.0%, and undifferentiated 30.0%, p<0.01), stage (stage I 96.9%, stage II 85.7%, stage III 56.3%, and stage IV 25.0%, p<0.01), and serious adverse events (yes versus no, 68.1% versus 92.2%, p=0.041) were significantly related to maternal overall survival in univariate analysis. In multivariate analysis, stage III/IV disease remained the independent prognostic factor associated with decreased maternal overall survival (stage III, hazard ratio 44.6, p<0.01; and stage IV, hazard ratio 399, p<0.01). In conclusion, although the majority of EOC cases during pregnancy resulted in live birth, maternal and neonatal mortality needs to be considered in the counseling and management of these pregnancies.

Revista Brasileira de Ginecologia E... Dec 2021To analyze the clinical and obstetric aspects of pregnant women with COVID-19.
OBJECTIVE
To analyze the clinical and obstetric aspects of pregnant women with COVID-19.
METHODS
A systematic literature review in the , , SCIELO, and CNKI databases was performed from March to May 2020, with the descriptors: ; ; ; , . Of those chosen were original titles, without language and period restriction and that addressed pregnant women with a clinical and/or laboratory diagnosis of COVID-19. Revisions, editorials, and duplicate titles were excluded. The Newcastle-Ottawa (NOS) and Murad et al. scales were used to assess the quality of the studies.
RESULTS
We included 34 articles with 412 pregnant women infected with severe acute respiratory syndrome (SARS-Cov-2), with an average age of 27.5 years of age and 36.0 gestational weeks. The most common symptom was fever (205 [49.7%]), and 89 (21.6%) pregnant women progressed to severe viral pneumonia. Laboratory tests showed an increase in C-reactive protein (154 [37.8%]), and radiological tests showed pneumonia with peripheral ground-glass pattern (172 [51.4%]). Emergency cesarean delivery was indicated for most pregnant women, and the most common gestational complication was premature rupture of ovarian membranes (14 [3.4%;]). We detected 2 (0.5%) neonatal deaths, 2 (0.5%) stillbirths, and 1 (0.2%) maternal death.
CONCLUSION
Pregnant women with COVID-19 presented a clinical picture similar to that of non-infected pregnant women, with few obstetric or neonatal repercussions. There was a greater indication of cesarean deliveries before the disease aggravated, and there was no evidence of vertical transmission of the infection.

Meta-Analysis Review
The purpose of the present systematic review is to clarify whether adjuvant chemotherapy improves survival rates in women with stage IC1 ovarian cancer. We searched Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar. We considered comparative observational studies and randomized trials that investigated survival outcomes (progression-free (PFS) and overall survival (OS)) among women with intraoperative rupture of early-stage epithelial ovarian cancer who received adjuvant chemotherapy and those that did not. Eleven studies, which recruited 7556 patients, were included. The risk of bias was defined as moderate after assessment with the Risk of Bias in non-Randomized Trials tool. Meta-analysis was performed with RStudio. Seven studies investigated the impact of adjuvant chemotherapy on recurrence-free survival of patients experiencing intraoperative cyst rupture for otherwise stage I ovarian cancer. The outcome was not affected by the use of adjuvant chemotherapy as the effect estimate was not significant (HR 1.24, 95% CI 0.74, 2.04). The analysis of data from 5 studies similarly revealed that overall survival rates were comparable among the two groups (HR 0.75, 95% CI 0.54, 1.05). This meta-analysis did not detect any benefit from adjuvant chemotherapy for stage IC ovarian cancer patients with cyst rupture. However, conclusions from this investigation are limited by a study population which included multiple histologic subtypes, high and low grade tumors and incompletely staged patients.

Meta-Analysis Review
BACKGROUND
Ovarian adult granulosa cell tumours are low-grade malignant sex cord-stromal neoplasm with a low recurrence rate. Prognostic factors for recurrence include tumor stage, tumor rupture in Stage I neoplasms and the presence of residual tumors after surgery. However, in recurrent tumors, prognostic factors for overall survival (OS) are lacking. In the present paper, we conducted a systematic meta-analysis with the aim to assess prognostic factors for OS in patients with recurrent GCT.
METHODS
Electronic databases were searched for all studies assessing prognostic factors in recurrent adult granulosa cell tumor of the ovary. Student T test, Fisher's exact test and Kaplan-Meier survival analysis with long-rank test were used to assess differences among groups; a p value < 0.05 was considered significant.
RESULTS
Eleven studies analyzing 102 recurrent tumors were included in the systematic review. Tumor stage and localization of recurrent tumors were significantly associated with OS on Kaplan-Meier analysis; Cox regression analysis showed a HR of 0.879 for the stage II, of 3.052 for the stage III, and of 2.734 for stage IV tumor was significantly associated with OS (p = 0.037); observed HRs for abdominal and thoracic locations were of 2.405 and of 4.024, respectively.
CONCLUSIONS
In conclusion, the present article emphasizes the prognostic significance of tumor stage > II and extrapelvic anatomic sites of recurrences in patients with recurrent granuolase cell tumors of the ovary.

Review
OBJECTIVE
This study aimed to synthesize the existing evidence on perinatal outcomes after autologous cryopreserved ovarian tissue transplantation, concurrently identifying key factors influencing these outcomes.
DATA SOURCES
A comprehensive search was performed on MEDLINE, Embase, and Cochrane Library databases to identify relevant studies on the effect of autologous cryopreserved ovarian tissue transplantation on perinatal outcomes from inception to October 22, 2023. Where there was missing information, the authors were contacted for updated data.
STUDY ELIGIBILITY CRITERIA
Observational studies, such as cohort studies, case series, and case reports that reported a live birth after autologous cryopreserved ovarian tissue transplantation, were considered eligible. Studies lacking data on women's demographic characteristics, autologous cryopreserved ovarian tissue transplantation procedure details, or perinatal outcomes were excluded. In addition, cases involving fresh or nonautologous transplantations and those addressing primary ovarian insufficiency were excluded.
METHODS
Two reviewers (M.E. and E.U.) independently performed the study selection, data extraction, and risk of bias assessment, and the results were then reviewed together. The PRISMA guidelines were followed, and the protocol was registered on PROSPERO (CRD42023469296).
RESULTS
This review included 58 studies composed of 122 women with 162 deliveries (154 singletons and 8 twins) after autologous cryopreserved ovarian tissue transplantation, resulting in 170 newborns. Of note, 83.6% of the women had a malignant disease. Moreover, most of these women (51.0%) were exposed to some form of chemotherapy before ovarian tissue cryopreservation. Of the 162 childbirths, 108 (66.7%) were conceived naturally, and 54 (33.3%) were conceived through assisted reproductive techniques. The birthweight of 88.5% of newborns was appropriate for gestational age, whereas 8.3% and 3.1% were small for gestational age and large for gestational age, respectively. The preterm birth rate was 9.4%, with the remaining being term deliveries. Hypertensive disorders of pregnancy were noted in 18.9% of women, including pregnancy-induced hypertension in 7.6%, preeclampsia in 9.4%, and hemolysis, elevated liver enzymes, and low platelet count in 1.9%. The incidences of gestational diabetes mellitus and preterm premature rupture of membranes were 3.8% for each condition. Neonatal anomalies were reported in 3 transplant recipients with 4 newborns: arthrogryposis, congenital cataract, and diaphragmatic hernia in a twin. Finally, among the recipients' characteristics, not receiving chemotherapy before ovarian tissue cryopreservation (odds ratio, 0.23; 95% confidence interval, 0.07-0.72; P=.012) and natural conception (odds ratio, 0.29; 95% confidence interval, 0.09-0.92; P=.035) were associated with a lower perinatal complication rate.
CONCLUSION
On the basis of low certainty evidence from observational studies, perinatal complication rates did not increase after autologous cryopreserved ovarian tissue transplantation compared with the general pregnant population, except for preeclampsia. This could be due to chemotherapy exposure, underlying medical conditions, and the common use of assisted reproductive techniques. Further larger studies are needed to explore the causes of increased preeclampsia incidence in autologous cryopreserved ovarian tissue transplantation pregnancies.
