ABSTRACT
STUDY OBJECTIVE: To define objective and readily applied diagnostic criteria for Y-shaped uteri using 3-dimensional transvaginal ultrasound (3D-TVUS) volume recordings. DESIGN: A retrospective case-control diagnostic measurements study. SETTING: A tertiary university hospital's reproductive health and research center. PATIENTS: Two hundred thirteen patients who presented with infertility between January 2020 and December 2022. INTERVENTIONS: Two blinded physicians re-evaluated the 3D-TVUS images of all patients for the presence of a uterine abnormality. The images of patients with a Y-shaped uterus were re-evaluated, and descriptive measurements were done. MEASUREMENTS AND MAIN RESULTS: The most common uterine abnormality in this cohort was the Y-shaped uterus with a prevalence of 12.2%, followed by the arcuate, T-shaped, and septate uteri, respectively. Reviewers identified 26 and 28 Y-shaped uteri, respectively, and came to a consensus on 25 images. Diagnostic criteria for the Y-shaped uterus based on 3D-TVUS findings have been specified as: lateral indentation depths between 4 and 7 mm, fundal indentation depth between 5 and 9 mm, lateral indentation angles between 121° and 149°, fundal indentation angle between 121° and 145°, and Y-angles 25° to 46°. CONCLUSION: Some subtypes of dysmorphic uteri, such as the Y-shaped uterus, whose clinical significance is unknown and may be variants of the normal, may actually be more common than thought. Determining objective diagnostic criteria with 3D-TVUS will allow standard research on these anomalies and their clinical significance.

OBJECTIVE: Magnesium sulfate (MgSO4) provides effective fetal neuroprotection. However, there is conflicting evidence regarding the association between antenatal MgSO4 exposure and patent ductus arteriosus (PDA). Thus, herein, we aimed to evaluate the association between antenatal MgSO4 exposure and PDA. STUDY DESIGN: Preterm infants born between 240/7 and 316/7 weeks of gestation were included in this retrospective study. Infants who died within the first 72 hours of life and those with significant congenital anomalies were excluded from the study. Echocardiographic and clinical assessment parameters were used to define PDA and hemodynamically significant PDA (hsPDA). Treatments were planned according to the standard protocols of the unit. The following data were collected from hospital medical records: perinatal characteristics, neonatal outcomes, detailed PDA follow-up findings, and maternal characteristics including MgSO4 exposure and doses. RESULTS: Of the 300 included infants, 98 (32.6%) were exposed to antenatal MgSO4. hsPDA rates were similar in the infants exposed and not exposed to antenatal MgSO4, when adjusted for antenatal steroid administration, gestational age, and birth weight (OR: 1.6, 95% CI: 0.849-3.118, p = 0.146). The rates of PDA ligation and open PDA at discharge were similar between the groups. A cumulative MgSO4 dose of >20 g was associated with an increased risk of hsPDA (crude OR: 2.476, 95% CI: 0.893-6.864, p = 0.076; adjusted OR: 3.829, 95% CI: 1.068-13.728, p = 0.039). However, the cumulative dose had no effect on the rates of PDA ligation or open PDA at discharge. Rates of prematurity-related morbidities and mortality were similar between the groups. CONCLUSION: Although antenatal MgSO4 exposure may increase the incidence of hsPDA, it may not affect the rates of PDA ligation or open PDA at discharge. Further studies are required to better evaluate the dose-dependent outcomes and identify the MgSO4 dose that not only provides neuroprotection but also has the lowest risk of adverse effects. KEY POINTS: · Antenatal exposure of MgSO4 may cause PDA.. · Antenatal MgSO4 exposure may not increase the rates of PDA ligation or open PDA at discharge.. · Further studies are required to better evaluate the dose-dependent outcomes and optimal MgSO4 dose..

The present narrative review aims to discuss the available data on the incidence and the risk factors of uterine fibroids (UFs) recurrence after different types of conservative surgical or radiologic procedures in women wishing to preserve their uterus. UFs are the most common benign tumors in women all over the world. Clinical presentation, including abnormal uterine bleeding (AUB), pelvic pain, bulky symptoms, and infertility affect patients' quality of life, and a large variety of conservative treatments are available especially for those with desire of pregnancy. Fertility sparing surgery, by either laparoscopy, hysteroscopy or laparotomy, or radiological interventions (uterine artery embolization, high-intensity focused ultrasound or magnetic resonance-guided focused ultrasound), are the most common therapeutic approaches. However, the genetic or acquired predisposition to UFs remain despite the treatments, and the recurrences are frequently described in a large percentage of patients. The most relevant risk factors for recurrence of UFs are young age at the first surgery, incomplete fibroid resection, the presence of multiple lesions, an enlarged uterus, and the coexistence with other pelvic diseases. The discussion on the possible medical strategy to reduce the recurrence is an open field of clinical investigation, in particular by using hormonal drugs.
