Objective:  Placenta accreta spectrum (PAS) is a term used to describe trophoblast invasion into the uterine wall. The condition can be FATAL: at labor due to a lack of spontaneous separation of the placenta from the uterine wall, leading to severe hemorrhage. In this study, we aim to evaluate preoperative risk factors for unplanned immediate hysterectomy in PAS uterine-preserving surgeries.

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.

Article Synopsis
  • The study aimed to assess how the introduction of pneumococcal conjugate vaccines (PCVs) affected orbital complications in children with acute rhino-sinusitis (OC-ARS) from 2002 to 2019.
  • Researchers analyzed data from 265 pediatric patients, dividing them into three groups: before the introduction of PCV7, between PCV7 and PCV13, and after PCV13.
  • Results showed a significant drop in the overall incidence of OC-ARS, especially in children aged 0-4 years, but there was an increase in the severity of the disease after PCVs were introduced.

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.

Article Synopsis
  • The study investigates the link between sinonasal anatomical variations and the likelihood of developing orbital complications related to acute rhinosinusitis in children.
  • It uses CT scans from 57 pediatric patients to identify anatomical differences that may influence which side is affected by these complications.
  • Findings suggest that variations like lamina papyracea dehiscence are significantly associated with an increased risk of complications on the same side, highlighting the need for further research to clarify these associations.

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.

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.

Objectives: To compare delivery outcomes of pregnancies diagnosed with placenta-accreta-syndrome (PAS) who underwent conservative treatment to patients who underwent cesarean hysterectomy.

Methods: A retrospective study of all women diagnosed with PAS treated in one tertiary medical center between 03/2011 and 11/2020 was performed. Comparison was made between conservative management during cesarean delivery and cesarean hysterectomy.

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 ( = 1068); and (2) those who delivered by CS due to arrest of descent at the second stage of labor ( = 603).

Article Synopsis
  • The study aimed to identify risk factors linked to bladder injuries during surgeries for placenta accreta spectrum (PAS) in pregnant women.
  • Out of 312 participants, there was a 9.3% rate of bladder injuries, with risk factors including previous cesarean deliveries and preoperative suspicion of placenta percreta.
  • Understanding these risk factors can improve preoperative planning and management during PAS surgeries.

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.

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.
