Infracoccygeal/transperineal window: new method to prenatally diagnose and classify level of anal atresia.
Ultrasound Obstet Gynecol
October 2024
Objectives: To introduce a two-dimensional sonographic method to assess the fetal anus, and to evaluate the feasibility of this method to diagnose anal atresia prenatally and identify the presence or absence of anoperineal fistula (in males) and anovestibular fistula (in females).
Methods: This was an observational study of suspected cases of anal atresia referred to a single center in Israel between August 2018 and October 2023. In addition to conventional evaluation of the perineum in the axial plane, fetuses referred to our center for suspected malformation were scanned with a new method termed the 'infracoccygeal/transperineal window'.
Article Synopsis
- - COVID-19 continues to pose risks to health, including long COVID, necessitating ongoing evaluation of vaccines and immunity against different variants of the virus.
- - A study analyzed immunity levels from vaccines, past infections, and hybrid immunity from December 2021 to August 2023 in Czechia, finding that recent booster vaccination significantly protects against severe COVID-19, while older vaccinations achieve less protection.
- - The study concludes that while vaccination is still effective in preventing severe COVID-19, its effects diminish over time, emphasizing the need for booster shots, and that prior immunity offers limited protection against long COVID after infection.
Purpose: The surgical technique for uterine closure following cesarean section influences the healing of the cesarean scar; however, there is still no consensus on the optimal technique regarding the closure of the endometrium layer. The aim of this study was to compare the effect of closure versus non-closure of the endometrium during cesarean section on the risk to develop uterine scar defect and associated symptoms.
Methods: A randomized prospective study was conducted of women undergoing first elective cesarean section at a single tertiary medical center.
Ultrasound appearance of decidualized non-ovarian endometriotic lesions during pregnancy and after delivery.
Ultrasound Obstet Gynecol
February 2024
Objective: To evaluate the changes in the ultrasound characteristics of decidualized non-ovarian endometriotic lesions that occur during pregnancy and after delivery.
Methods: This was a prospective observational cohort study carried out at a single tertiary center between December 2018 and October 2021. Pregnant women with endometriosis underwent a standardized transvaginal ultrasound examination with color Doppler imaging once in every trimester and after delivery.
Research Question: Is there association between the presence of a uterine niche and the presence of symptoms?
Design: This cross-sectional study was conducted at a single tertiary medical centre. All women who underwent Caesarean section from January 2017 to June 2020 were invited to the gynaecological clinics, and requested to complete a questionnaire regarding symptoms related to the presence of a niche (heavy menstrual bleeding, intermenstrual spotting, pelvic pain, infertility). Transvaginal two-dimensional ultrasonography was performed to assess the uterus and uterine scar characteristics.
