RESUMO
OBJECTIVE: This study aimed to investigate maternal and neonatal outcomes in subsequent pregnancies of women with a history of placenta accreta spectrum (PAS) compared with women without history of PAS. STUDY DESIGN: A retrospective cohort study conducted at a single tertiary center between March 2011 and January 2022. We compared women with a history of PAS who had uterine preservation surgery and a subsequent pregnancy, to a control group matched in a 1:5 ratio. The primary outcome was the occurrence of a composite adverse outcome (CAO) including any of the following: uterine dehiscence, uterine rupture, blood transfusion, hysterectomy, neonatal intensive care unit admission, and neonatal mechanical ventilation. Multivariable logistic regression was performed to evaluate associations with the CAO. RESULTS: During the study period, 287 (1.1%) women were diagnosed with PAS and delivered after 25 weeks of gestation. Of these, 32 (11.1%) women had a subsequent pregnancy that reached viability. These 32 women were matched to 139 controls. There were no significant differences in the baseline characteristics between the study and control groups. Compared with controls, the proportion of CAO was significantly higher in women with previous PAS pregnancy (40.6 vs. 19.4%, p = 0.019). In a multivariable logistic regression analysis, previous PAS (adjusted odds ratio [aOR] = 3.31, 95% confidence interval [CI] = 1.09-10.02, p = 0.034) and earlier gestational age at delivery (aOR = 3.53, 95% CI = 2.27-5.49, p < 0.001) were independently associated with CAOs. CONCLUSION: A history of PAS in a previous pregnancy is associated with increased risk of CAOs in subsequent pregnancies. KEY POINTS: · The uterine-preserving approach for PAS delivery is gaining more attention and popularity in recent years.. · Women with a previous pregnancy with PAS had higher rates of CAOs in subsequent pregnancies.. · Previous PAS pregnancy is an independent factor associated with adverse outcomes..
RESUMO
PURPOSE: Pregnancies complicated by placenta accreta spectrum (PAS) are associated with severe maternal morbidities. The aim of this study is to describe the neonatal outcomes in pregnancies complicated with PAS compared with pregnancies not complicated by PAS. METHODS: A retrospective cohort study conducted at a single tertiary center between 03/2011 and 01/2022, comparing women with PAS who underwent cesarean delivery (CD) to a matched control group of women without PAS who underwent CD. We evaluated the following adverse neonatal outcomes: umbilical artery pH < 7.0, umbilical artery base excess ≤ - 12, APGAR score < 7 at 5 min, neonatal intensive care unit (NICU) admission, mechanical ventilation, hypoxic ischemic encephalopathy, seizures and neonatal death. We also evaluated a composite adverse neonatal outcome, defined as the occurrence of at least one of the adverse neonatal outcomes described above. Multivariable regression analysis was used to determine which adverse neonatal outcome were independently associated with the presence of PAS. RESULTS: 265 women with PAS were included in the study group and were matched to 1382 controls. In the PAS group compared with controls, the rate of composite adverse neonatal outcomes was significantly higher (33.6% vs. 18.7%, respectively, p < 0.001). In a multivariable logistic regression analysis, Apgar score < 7 at 5 min, NICU admission and composite adverse neonatal outcome were independently associated with PAS. CONCLUSION: Neonates in PAS pregnancies had higher rates of adverse outcomes. Apgar score < 7 at 5 min, NICU admission and composite adverse neonatal outcome were independently associated with PAS.

INTRODUCTION: Dysgerminoma is a histologic subtype of malignant ovarian germ cell tumor (MOGCT). Most publications describing dysgerminoma are of small cohorts. Large cohorts usually describe MOGCT as a group, and therefore, drawing specific conclusions regarding dysgerminomas is challenging. In this study, we sought to highlight and review the most recently published data on dysgerminoma. EVIDENCE ACQUISITION: We performed an electronic search in PubMed, using a range of medical subject heading terms (MeSH), including English language articles only, published earliest in 2010. Papers including "germ cell tumors," and "dysgerminoma" were included. We excluded reviews, meta-analyses, and case reports. We followed the PRISMA guidelines to prepare this review. All included articles were reviewed by two reviewers (LF, GL). EVIDENCE SYNTHESIS: We found that dysgerminomas mostly present in an early stage of the disease and therefore harbor a favorable prognosis. Most dysgerminomas occur in women of reproductive age, in which fertility-sparing treatment is safe. While complete staging surgery for all patients is debatable, adjuvant chemotherapy seems to be beneficial. Long-term follow-up by a gynecologic oncologist is necessary as recurrence may occur. CONCLUSIONS: Since most studies are small and retrospective, the development of multicenter prospective studies protocols is of utmost importance to study future lines of therapy.
RESUMO
INTRODUCTION: As the role of sinonasal anatomical variants as predisposing factors in determining the lateralization of acute rhinosinusitis-related orbital complications (ARS-OC) in pediatrics remains a topic of debate, this study further explores the potential association between anatomical variations and ARS-OC. METHODS: A retrospective study was conducted on children who had been admitted with ARS-OC using medical records and sinus CT scans to compare anatomical differences between the affected and contralateral sides. This study aimed to identify bony anatomical disparities that may impact OC laterality secondary to ARS. The anatomical features examined included septal deviation, concha bullosa, lamina papyracea dehiscence (LPD), and uncinate process abnormalities. RESULTS: The CT scans of 57 pediatric patients (114 sides) were reviewed. Our results indicated that bony anatomical variations were associated with ARS-OC laterality (63 % vs. 37 %, P = 0.006), yielding an odds ratio of 2.91. Additionally, our study revealed a significant association between ipsilateral LPD with the increased risk of ARS-OC (39 % vs. 1.8 %, P < 0.05), with an odds ratio of 34.3 compared to the opposite side. CONCLUSIONS: LPD might play a role in the pathophysiology of pediatric ARS-OC, as it is associated with a significantly higher risk of affecting the ipsilateral side. Further research is necessary to determine whether LPD is a causative factor or a result of ARS.

OBJECTIVES: To evaluate the impact of the pneumococcal conjugate vaccines (PCVs) introduction on the orbital complications of acute rhino-sinusitis (OC-ARS). METHODS: A retrospective cohort study of all pediatric patients with OC-ARS during the period 2002-2019. Data included clinical, demographic, laboratory, and microbiology findings. Patients were divided into three groups: before PCV7 introduction (group 1), after PCV7 and before PCV13 (group 2), and after PCV13 (group 3). RESULTS: Of 265 enrolled patients, 117, 39, and 109 were assigned to groups 1, 2, and 3. During the study period, a significant decrease was recorded in the percentages of patients in Chandler classification severity category 1, with an increase in patients in category 3 (P = 0.011). The yearly incidence of OC-ARS decreased from 12.64 cases per 100,000 population in 2002 to 5.56 per 100,000 in 2008, and 2.99 per 100,000 in 2019 (P < 0.001). Patients aged 0-4 years showed a dramatic decrease from 29 cases per 100,000 population in 2002 to 4.27 per 100,000 in 2019 (P < 0.001). The pathogens retrieved from all cultures performed were Streptococcus pneumoniae (32.5%), non-typeable Haemophilus influenzae (27.5%), Streptococcus Species, (12.5%), and Staphylococcus aureus (20%), with no changes in distribution during the study periods. Surgery was performed in 28 (10.6%) patients. CONCLUSIONS: A significant decrease was seen in the overall incidence of OC-ARS, mainly attributable to the decrease in patients aged 0-4 years. An increase was recorded in the severity of the disease following PCVs introduction.
RESUMO
OBJECTIVES: The objectives of this study were to determine in a population-based cohort study the association between cesarean section (CS) during the second stage of labor and the risk for preterm birth and/or cervical insufficiency in the subsequent pregnancy; to identify maternal and neonatal risk factors for long-term complications following CS due to prolonged second stage of labor. METHODS: We conducted a retrospective population-based cohort study including women who had at least one consecutive delivery following a CS at our institution from 1991 to 2018, provided that the first delivery was at term. We divided the study cohort into two groups: (1) women who delivered by CS due to failure to progress during the first stage of labor (n = 1068); and (2) those who delivered by CS due to arrest of descent at the second stage of labor (n = 603). RESULTS: Of the 120,147 women who met the inclusion criteria, 78,407 had a subsequent delivery during the study period. Women of group 1 were significantly older than those of group 2 (p = .018), and had a higher rate of assisted reproductive technology [61 (5.7%) vs. 18 (3.1%), p < .022,]. Additionally, their hospitalization period was significantly longer (p < .001). The rate of preterm birth in the subsequent delivery was higher among women who had a CS due to arrest of descent than those who had a CS due to arrest in dilatation [43 (7.3%) vs 49 (4.6%), p < .026]. This was confirmed after adjusting for confounding factors In a multivariable regression analysis (OR 1.78, 95% CI 1.14-2.76, p value = .011) A Cox regression analysis implying gestational age at delivery at the time factor identifies CS due to arrest of descent as a risk factor for subsequent preterm birth (Hazard ratio 1.19 95% CI 1.07-1.31). CONCLUSION: CS due to arrest of descent is an independent risk factor for subsequent preterm birth. The exact mechanisms contributing to this association are yet to be determined. SYNOPSIS: Cesarean section during the second stage of labor is an independent risk factor for late preterm birth in the subsequent pregnancy when compared to cesarean section in the first stage of labor.

OBJECTIVES: To identify risk factors associated with bladder injury during placenta accreta spectrum (PAS) surgeries. METHODS: This retrospective cohort study was conducted at the Chaim Sheba Medical Center. The study population included pregnant women diagnosed with PAS undergoing uterine-preserving surgery or hysterectomy. Women with and without operative bladder injury were compared by univariate analysis followed by multivariate analysis. A sub-analysis of women without preoperative sonographic suspicion of bladder invasion was performed. RESULTS: A total of 312 women were included in the study. Bladder injury incidence was 9.3% (n = 29). Uterine preservation was performed in 267/312 (85.6%) women. The number of previous cesarean deliveries and a preoperative sonogram suspicious for placenta percreta were found to be independent risk factors for intraoperative bladder injury (odds ratio [OR] 1.30, P = 0.019, and OR 5.23, P = 0.002, respectively). The number of previous cesarean deliveries and preoperative sonographic suspicion of placenta percreta were also associated with bladder injury in the sub-analysis (OR 1.30, P = 0.044 for previous cesarean deliveries, and OR 3.36, P = 0.036, for preoperative suspicion of bladder injury). CONCLUSION: The number of previous cesarean deliveries and preoperative suspicion of placenta percreta are preoperative factors that can assist in preoperative planning and intraoperative management of PAS cases.

OBJECTIVES: Recently, a new standardized sonographic evaluation system for cesarean scar pregnancies (CSP) was published. We aimed to evaluate the clinical outcomes of CSP cases according to the new sonographic evaluation and reporting system. STUDY DESIGN: A retrospective study conducted at a single tertiary center. All CSPs between 1/2011 and 4/2022 were included. Cases were evaluated by expert sonographers and classified into three categories: 1) CSP in which the largest part of the gestational sac (GS) protrudes towards the uterine cavity; 2) CSP in which the largest part of the GS is embedded in the myometrium but does not cross the serosal contour; and 3) CSP in which the GS is partially located beyond the outer contour of the cervix or uterus.Baseline characteristics, management and outcomes were compared between the three categories. RESULTS: Overall, 55 patients were diagnosed with CSP during the study period; 10 (18.1 %) type 1, 31 (56.3 %) type 2, and 14 (25.4 %) type 3. Baseline characteristics were similar among groups. Compared with type 2 and 3, patients diagnosed with CSP type 1 received less methotrexate treatment [83.9 % and 78.6 % vs. 40.0 %, respectively, p = 0.020]. The rates of need for invasive procedures, urgent procedures, major bleeding, length of hospitalization, and subsequent pregnancies were similar between groups. CONCLUSIONS: No clinically significant differences were found between groups divided by the new standardized sonographic evaluation and reporting system for CSP in pregnancy characteristics, management, and subsequent pregnancy outcomes. Further investigation is required to enable informed management of CSP based on the new sonographic reporting system.

OBJECTIVES: General gynecologists are often the first to face a newly diagnosed adnexal mass. Bothering mass symptoms, fertility issues, and the effect of a possible surgical intervention on fertility in term of mechanical factor and ovarian follicular reserve are all considerations that should be accounted for. This study summarizes and compares five different adnexal mass management guidelines, enabling clinicians to peruse consensus and controversy issues, thus choosing the optimal management method. DESIGN: We retrieved, reviewed and compared the most recent national guidelines of adnexal mass management from the national societies of the United States (American College of Obstetricians and Gynecologists), England (the Royal College of Obstetricians and Gynecologists), Canada (the Society of Obstetricians and Gynaecologists of Canada), Australia (the Royal Australian College of General Practitioners), and France (French College of Gynaecologists and Obstetricians). RESULTS: There is a broad consensus regarding the role of transvaginal ultrasound as part of the initial evaluation of an adnexal mass and the radiological characteristics suggesting it being malignant. The role of transabdominal ultrasound or doppler mode is controversial. The use of MRI in cases of indeterminate adnexal masses is widely accepted. Ultrasound-guided aspiration is generally not recommended. There is a broad consensus that CA-125 should not be used as an ovarian cancer disease screening tool, though its role in the initial evaluation of adnexal masses is controversial. Risk prediction models are generally accepted, particularly the 'International Ovarian Tumor Analysis simple rules' and the 'Risk of Malignancy Index'. CONCLUSION: Adnexal mass management national guidelines, though similar, had noticeable variations in the content, references cited, and recommendations made. While this variation might raise a concern as to the reproducibility of synthesizing literature, it can help practitioners present all spectra of recommendations and available data.

OBJECTIVE: To evaluate the effect of the coronavirus disease 2019 (COVID-19) mask-wearing on hematological laboratory components and obstetrical outcomes among women delivering during the COVID-19 pandemic. METHODS: Laboratory results and obstetrical outcomes of women with singleton gestations, admitted for delivery during the COVID-19 mask-wearing period (April-June 2020) were compared with those of women delivering during the parallel period in 2019 and with a larger cohort derived from nine pre-pandemic years (March 2011-April 2020). RESULTS: Overall, 1838 women delivered during the COVID-19 pandemic. Compared with the pre-pandemic period, mean hemoglobin and fibrinogen levels were significantly higher during the mask-wearing period (12.15 ± 1.1 vs 11.96 ± 1.2, P < 0.001 and 472 ± 103.6 vs 448 ± 85.1 mg/dl, P < 0.001, respectively). Platelet levels were lower (200 ± 56.0 vs 206 ± 57.5 K/µl, P < 0.001). The rate of delivery at <34 weeks of gestation was lower during the mask-wearing period (1.1% vs 2%, odds ratio [OR] 0.57, 95% confidence intervals [CI] 0.37-0.88, P = 0.01), whereas cesarean delivery and postpartum hemorrhage rates were higher (26.7% vs 24.4%, OR 1.13, 95% CI 1.02-1.25, P = 0.022 and 4.1% vs 2.8%, OR 1.5, 95% CI 1.2-1.8, P = 0.001, respectively). CONCLUSION: A hard-to-ventilate space created by wearing a mask during the COVID-19 era may be the underlying cause of the observed higher hemoglobin level among pregnant women, possibly affecting obstetrical outcomes.
