Objectives:
This study aims to correlate pelvic ultrasound with female puberty and evaluate the usual ultrasound parameters as diagnostic tests for the onset of puberty and, in particular, a less studied parameter: the Doppler evaluation of the uterine arteries.
Methods:
Cross-sectional study with girls aged from one to less than eighteen years old, with normal pubertal development, who underwent pelvic ultrasound examination from November 2020 to December 2021. The presence of thelarche was the clinical criterion to distinguish pubescent from non-pubescent girls. The sonographic parameters were evaluated using the ROC curve and the cutoff point defined through the Youden index (J).
Results:
60 girls were included in the study. Uterine volume ≥ 2.45mL had a sensitivity of 93%, specificity of 90%, PPV of 90%, NPV of 93% and accuracy of 91% (AUC 0.972) for predicting the onset of puberty. Mean ovarian volume ≥ 1.48mL had a sensitivity of 96%, specificity of 90%, PPV of 90%, NPV of 97% and accuracy of 93% (AUC 0.966). Mean PI ≤ 2.75 had 100% sensitivity, 48% specificity, 62% PPV, 100% NPV and 72% accuracy (AUC 0.756) for predicting the onset of puberty.
Conclusion:
Pelvic ultrasound proved to be an excellent tool for female pubertal assessment and uterine and ovarian volume, the best ultrasound parameters for detecting the onset of puberty. The PI of the uterine arteries, in this study, although useful in the pubertal evaluation, showed lower accuracy in relation to the uterine and ovarian volume.

Objective
To analyze whether acetylsalicylic (ASA) intake modifies the mean uterine arteries pulsatility index (UtA-PI) at the 2nd or 3rd trimester in a cohort of pregnant women with abnormal mean UtA-PI at between 11 and 14 weeks of gestation.
Methods
This is a retrospective cohort study. Singleton pregnancies with abnormal mean UtA-PI at between 11 and 14 weeks of gestation were studied. The participants were divided into 3 groups: 1) If the participant did not take ASA during pregnancy; 2) If the participant took ASA before 14 weeks of gestation; and 3) If the participant took ASA after 14 weeks of gestation. The mean UtA-PI was evaluated at the 2nd and 3rd trimesters, and it was considered to improve when it decreased below the 95th percentile. The prevalence ratio (PR) and the number needed to treat (NNT) werecalculated.
Results
A total of 72 participants with a mean UtA-PI>95th percentile at the 1st trimester of gestation were evaluated. Out of the 18 participants who took ASA, 8 participants started it before 14 weeks of gestation and 10 after. A total of 33.3% of these participants had improved the mean UtA-PI at the 2nd and 3rd trimesters of gestation, although it was not statistically significant (p=0.154). The prevalence ratio was 0.95 (95% confidence interval [CI]: 0.31-1.89), but between the 1st and 2nd trimesters of gestation, the PR was 0.92 (95%CI: 0.21-0.99) and it was statistically significant.
Conclusion
The present work demonstrates a modification of the mean UtA-PI in participants who took ASA compared with those who did not. It is important to check if ASA can modify the normal limits of uterine arteries because this could have an impact on surveillance.

Views82See morePreeclampsia, which affects about 3 to 5% of pregnant women, is the most frequent medical complication in pregnancy and the most important cause of maternal and perinatal morbidity and mortality. During the past three decades, numerous clinical, biophysical, and biochemical screening tests have been proposed for the early detection of preeclampsia. Literature shows large discrepancies in the sensitivity and predictive value of several of these tests. No single screening test used for preeclampsia prediction has gained widespread acceptance into clinical practice. Instead, its value seems to be in increasing the predictive value of panels of tests, which include other clinical measurements. The aim of this review was to examine the combination of maternal risk factors, mean arterial blood pressure, and uterine artery Doppler, together with biomarkers in the preeclampsia prediction.

Views63See morePurpose: to evaluate the results of uterine artery embolization (UAE) in the treatment of uterine leiomyomas. Methods: eighteen patients with ultrasonographic diagnosis of uterine leiomyomas were submitted to UAE with polyvinyl alcohol (PVA) particles. The femoral arteries are the access sites until selective catheterization of the uterine arteries. Imaging regarding uterine volume was performed before the procedure and three months after wards. Clinical follow-up was performed at regular intervals after the procedure to assess patient menstrual characteristics and uterine volume. Results: three procedures were technically unsuccessful because of failure of superselective catheterization. Control of menorrhagia and pelvic pain was reported at three months after the procedure by 86 and 60% of patients, respectively. The initial mean uterine volume was 381 cm³ and after 3 months, 263 cm³. The mean uterine volume reduction was 27.4% after three months of follow-up. Clinical and biochemical findings consistent with ovarian failure were observed in three (20%) patients. Conclusions: UAE represents a new therapeutic approach in the treatment of uterine leiomyomas. The risk of ovarian failure after the procedure limits its use to patients aged 45 years or without pregnancy wish.
