Article Synopsis
  • - The study investigates the impact of the Restifem® pessary on pelvic floor function in postpartum women, evaluating its effectiveness as both a preventive and therapeutic device from 6 weeks to 12 months after delivery.
  • - 857 women participated, with 137 using the pessary and 133 not; findings revealed that pessary users experienced significantly worse pelvic floor function initially but showed greater improvement in scores related to bladder and pelvic organ prolapse over time.
  • - The results suggest that using the pessary contributes to improved recovery of pelvic floor function, particularly for women experiencing higher levels of dysfunction postpartum, while also highlighting the study's legitimacy through registration in a clinical trials database.

Objectives: To compare the effectiveness, safety and patient satisfaction of a double balloon catheter (DB) with a synthetic osmotic cervical dilator (OD) for pre-induction cervical ripening in an outpatient setting.

Methods: This is a prospective, dual-center pilot study including 94 patients with an unripe cervix (Bishop Score <6) near term; 50 patients received the DB and 44 patients the OD. The primary outcomes were the difference in BishopScore (BS) and cervical shortening.

Introduction: About one in 500 pregnant women requires a surgical intervention that is not pregnancy-related. One of the most common surgical interventions during pregnancy is appendectomy. The primary aim of this study was to assess surgical access of appendectomy during pregnancy and pregnancy outcome.

Objectives: The Organisation for Economic Cooperation and Development (OECD) estimates an average maternal mortality rate (MMR) of around 3.4 maternal deaths per 100,000 live births for 2019-2021, based on relevant diagnoses on death certificates. However, Germany does not currently have a registry for recording the number of maternal deaths.

Mechanical methods have gained growing interest for pre-induction cervical ripening in women with an unripe cervix, since they have a better safety profile compared to prostaglandins. Balloon catheters have been the gold standard method for decades, while there was a lack of data on synthetic osmotic cervical dilators. Not until 2015, when Dilapan-S was approved by the Food and Drug Administration (FDA) for induction of labor, numerous studies have been published on the use of Dilapan-S in this field.

Introduction: Pregnant women and their offspring represented a vulnerable patient collective during the Covid-19 pandemic. Beyond the direct effect of SARS-CoV-2 via vertical transmission, an indirect impact on the fetus can occur through placental lesions deteriorating placental villous function. We performed a histopathological analysis of placentas of parturients with SARS-CoV-2 compared to healthy controls.

Purpose: Pelvic floor disorders are common and associated with pregnancy and childbirth. For restitution of pelvic floor connective tissue and thereby therapy of postpartum pelvic organ prolapse and stress urinary incontinence, the Restifem pessary is approved. It supports the anterior vaginal wall behind the symphysis, the lateral sulci and the sacro-uterine ligaments and stabilises the connective tissue.

Purpose: The purpose of this study was to determine the frequency of detection of isthmoceles by ultrasound 6 months after caesarean section (CS) and which symptoms associated with isthmocele formation occur after CS. Subsequently, it was determined how often the ultrasound finding "isthmocele" coincided with the presence of complaints.

Methods: A prospective multicentre cohort study was conducted with 546 patients from four obstetric centres in Berlin, who gave birth by primary or secondary CS from October 2019 to June 2020.

Objectives: With an increasing incidence of labor induction the socioeconomic costs are increasing and the burden on hospital capacities is rising. In addition, the worldwide SARS-CoV-2 pandemic asks for improvements in patient care during pregnancy and delivery while decreasing the patient-staff contact. Here, we are retrospectively analyzing and comparing a mechanical ripening device that is utilized as an outpatient procedure to misoprostol and dinoprostone as inpatient induction methods in a low risk cohort.

Article Synopsis
  • A study evaluated the effectiveness of human epididymis protein 4 (HE4), cancer antigen 125 (CA125), and the risk of malignancy algorithm (ROMA) in detecting ovarian cancer in patients with a pelvic mass, alongside traditional ultrasound methods.
  • Among 965 patients, those with advanced-stage ovarian cancer showed excellent biomarker performance (AUC > 0.92), but the diagnostic accuracy was lower for early-stage cancers (AUC < 0.77).
  • ROMA and HE4 were especially useful in distinguishing ovarian cancer from endometriosis in premenopausal women, while CA125 was found to be more reliable for postmenopausal patients.

There are currently no up-to-date evidence-based recommendations on the preferred method to induce labour after previous Caesarean section, especially for patients with unripe cervix, as randomised controlled studies are lacking. Intravenous oxytocin and misoprostol are contraindicated in these women because of the high risk of uterine rupture. In women with ripe cervix (Bishop Score > 6), intravenous administration of oxytocin is an effective procedure with comparable rates of uterine rupture to those with spontaneous onset of labour.

Background: Puerperal mastitis, as well as breast abscess, are common complications that can arise during the breastfeeding period. Acute-onset quadriplegia has been described as a complication of bacterial or viral infections. Here we report a case of puerperal breast abscess with transient acute-onset staphylococcal mediated quadriplegia.

Objectives: The fifth of the United Nations' Millennium Development Goals proposed for 2000-2015 was to improve maternal health, which has only partially been achieved. Worldwide, the maternal mortality ratio is currently estimated at 216/100.000 livebirths, compared to 380/100,000 in 1990.

Background: In Germany, performing fertility procedures involving oocyte donation is illegal, as stated by the Embryo Protection Law. Nonetheless, in our clinical routine we attend to a steadily rising number of pregnant women, who have sought oocyte donation abroad. Due to the legal circumstances many women opt to keep the origin of their pregnancy a secret.

Experimental and clinical studies suggest that prenatal experiences may influence health trajectories up to adulthood and high age. According to the hypothesis of developmental origins of health and disease exposure of pregnant women to stress, nutritional challenges, infection, violence, or war may "program" risks for diseases in later life. Stress and anxieties can exist or be provoked in parents after fertility treatment, after information or diagnosis of fetal abnormalities and demand simultaneous caring concepts to support the parents.

Objectives: Worldwide, the overall cesarean section is rising. Trial of labor after cesarean (TOLAC) is an overall safe option with an immediate impact on neonatal and maternal short- and long-term health. Since the use of prostaglandins in cervical ripening is associated with an increased risk of uterine rupture, mechanical methods as balloon catheters or osmotic dilators have been suggested for cervical ripening prior to induction of labour.

Introduction: SARS-CoV-2 is a novel coronavirus that was first isolated in Wuhan, China, and resulted in a rapidly spreading pandemic worldwide. Currently there is only limited evidence on the effect of COVID-19 on pregnant women.

Case: Here we present one of the first serious COVID-19 cases in pregnancy at term with subsequent delivery.

Aim: The misoprostol vaginal insert (MVI) was reported to be more effective than dinoprostone but discussed critically because of high rates of fetal heart rate changes due to uterine tachysystole. The aim of this study was to investigate the outcome of induced labor using the MVI compared to off-label orally-administered misoprostol (OM).

Methods: Retrospective study including a total of 401 patients with singleton pregnancies in whom labor was induced at ≥36 0/7 gestational weeks with MVI (203) or OM (198).

Background: Maternal hypotension is a common side effect of spinal anaesthesia for Caesarean section. The combination of colloid coloading and vasopressors was considered our standard for its prevention and treatment. As the safety of hydroxyethyl starch is under debate, we replaced colloid with crystalloid coloading.
