Purpose: Transvaginal ultrasound (TVUS) is used in routine practice to evaluate cervical length (CL). This technique is nevertheless invasive and often viewed as uncomfortable, which is less the case with transperineal ultrasound (TPUS). This study was conducted in light of recent technological improvements in the ultrasound field to evaluate whether TPUS could be used as an alternative to TVUS in CL assessment.

Article Synopsis
  • Chorionic villus sampling (CVS) offers quicker results for detecting genetic abnormalities compared to amniocentesis, but it has a higher rate of incomplete results, prompting this study to seek risk factors for such failures.
  • The study, conducted from January 2014 to December 2018, involved 214 CVS procedures, revealing that 34% resulted in failures, with significant differences noted between successful and failed cases related to BMI, gestational age, trophoblastic location, and type of sampling approach.
  • Key factors negatively impacting the success of CVS included higher BMI, the posterior position of the trophoblast, and a transcervical sampling method; these findings suggest considering amni

Objectives: Ultrasonography plays a key role in surveillance of gastroschisis. Indeed, ultrasound should allow an early diagnosis of its specific complications all the while avoiding their over-diagnosis which could induce an unnecessary prematurity in these fragile children. The aim of this study was to evaluate the relevance of ultrasonography in the surveillance of this malformation.

Objective: Large loop excision of the transformation zone (LLETZ) conization has been associated with adverse obstetrical outcomes. In an approach to reduce the number of performed LLETZ procedures, we conducted this study to evaluate whether "diagnostic" LLETZ should still be performed, by analyzing their yield in terms of detection (and treatment) of real high-grade squamous intraepithelial lesion (HSIL).

Methods: During a two-year study period, all patients who underwent a LLETZ procedure in our institution were retrospectively included.

Objectives: Not being able to completely examine the cervical squamocolummar junction (SCJ) in colposcopy after large loop excision of the transformation zone (LLETZ) is an important issue regarding surveillance, as high-grade cervical intra-epithelial neoplasia recurrence risk is high. This study was conducted in order to identify risk factors for post-LLETZ unsatisfactory colposcopy.

Methods: This prospective multicenter observational study was performed in nine French University hospitals, with inclusions running from December 2013 to December 2017.

Aim: Labor management is often considered to be stressful. Increases in cesarean section (CSD) and assisted vaginal (AVD) deliveries rates have been ascribed to inexperience. To address this issue, we observed the obstetric management activity of four obstetrics and gynecology registrars throughout their 2-year registrarship program.

After a small-for-gestational-age (SGA) birth, recurrence of placenta-mediated pregnancy complications (PMPCs) is a cause for anxiety when contemplating another pregnancy. We sought to identify factors potentially associated with this recurrence. This retrospective single-center observational study was conducted in a tertiary maternity unit between 1 January 2010 and 31 December 2017.

Article Synopsis
  • Facial femoral syndrome (FFS) is a rare congenital condition marked by underdeveloped femurs and distinctive facial features, often linked with other organ malformations, yet no clear genetic cause has been identified.
  • A study reviewed 92 FFS cases to improve diagnosis and investigate potential genetic factors, finding that 27.2% were suspected prenatally and that maternal diabetes affected 42.4% of patients.
  • Results indicated that hypoplasia was the most common femoral issue, retrognathia and cleft lip/palate were frequently present, while most individuals demonstrated normal intellectual development; emerging genetic methods may help uncover the underlying causes in the future.

  • Fetal ventriculomegaly (VM) is defined as the enlargement of fetal lateral ventricles above 10 mm, with some experts suggesting that cases under 12 mm may not require further ultrasound referral.
  • A study of 127 cases classified VM into three groups based on size and associated conditions, evaluating the outcomes for both pregnancy and infants after one month.
  • Results indicated that smaller VM cases had higher rates of healthy infants compared to larger cases or those with associated malformations, supporting the necessity for systematic ultrasound referrals for all cases of VM regardless of size.
