Exploring the influence of perineal biometrics and stiffness measured by elastography during pregnancy on perineal tears : A pilot study.

Objectives: This study aimed to describe the biometrics and elasticity of the perineal body and the anal sphincter in the ninth month of pregnancy and explore their association with the risk of perineal tears during childbirth.

Methods: In this prospective observational study, pregnant women at 36-40 weeks of gestation were included. Using transperineal 2D-mode ultrasound and shear wave elastography (SWE), we measured the biometrics and stiffness of the perineal body (PB), external anal sphincter (EAS), internal anal sphincter (IAS), and anal mucosa (AM) at rest and during Valsalva maneuvers.

Perineal deformation during forceps, vacuum and OdonAssist™ assisted vaginal deliveries: A simulation study based on advanced image processing.

Objectives: The aim of this study was to analyse influence of the fetal head position and the type of instrument used (forceps, vacuum, OdonAssist™) on perineal deformation, during simulated vaginal deliveries monitored by stereophotogrammetry.

Methods: An exploratory study was conducted using mannequins simulating vaginal births. Fifty simulated deliveries were performed with different fetal head positions and instruments: Pajot's forceps, Kiwi-vacuum, and OdonAssist™.

Evaluation of French practices in the management and the follow-up of obstetric anal sphincter injuries (OASIS).

Objective: The aim was to assess the current management and follow-up of obstetric anal sphincter injuries in maternity wards in France at two levels: the patient's and the care unit level.

Study Design: We carried out an evaluation of professional practices in all French maternity hospitals by sending a questionnaire that covered five areas: (i) general information about the hospital, (ii) immediate management of OASIS and postpartum care, (iii) patient follow up, (iv) management of a subsequent pregnancy, and (v) training of health professionals.

Results: During this period, 102 answers (22.

Fetal Presentation of MYRF-Related Cardiac Urogenital Syndrome: An Emerging and Challenging Prenatal Diagnosis.

Purpose: MYRF-related cardiac-urogenital syndrome (MYRF-CUGS) is a rare condition associated with heterozygous MYRF variants. The description of MYRF-CUGS phenotype is mostly based on postnatal cases and 36 affected individuals have been published so far. We aim now to delineate the prenatal phenotype of MYRF-CUGS by reporting clinical data from fetuses and neonates with a pathogenic MYRF variant.

Influence of experimental conditions on some in-vitro biomechanical properties of the sow's perineum.

The aim of this work was to develop an experimental protocol that takes into account the influence of experimental conditions on these perineal tissues, before determining their mechanical properties. Samples of each perineal tissue layer were obtained from the skin, the vagina, the external anal sphincter (EAS), the internal anal sphincter (IAS) and anal mucosa of freshly dead sows. They were tested in quasi-static uniaxial tension using the Mach-1 testing machine.
