[First trimester screening of late-onset preeclampsia in a low risk and low volume obstetrical setting: external validation of a predictive model].

Background: The external validation of predictive model of late preeclampsia in a low volume and low risk obstetrical setting.

Methods: A cohort was created of 174 singleton pregnancies of 11+0-13+6 gestational weeks at Clinica Universidad Navarra from September 2011 to March 2013, which was considered as a validation cohort of a previously described model for late PE (Hospital Clinic, Barcelona).

Results: A total of 7 (4%) women developed late PE.

Performance of three-dimensional power Doppler angiography as third-step assessment in differential diagnosis of adnexal masses.

Objective: To evaluate the contribution of three-dimensional (3D) power Doppler angiography (3D-PDA) to the differential diagnosis of adnexal masses.

Methods: This was a prospective study in women diagnosed with a persistent adnexal mass and subsequently scheduled for surgery in a tertiary university hospital. All women were evaluated by transvaginal/transrectal ultrasound according to a predetermined three-step protocol, with transabdominal ultrasound being performed in some cases.

Contribution of power Doppler blood flow mapping to gray-scale ultrasound for predicting malignancy of adnexal masses in symptomatic and asymptomatic women.

Objective: To determine the contribution of power Doppler blood flow mapping to gray-scale ultrasound for predicting malignancy of adnexal masses in symptomatic and asymptomatic women.

Study Design: One thousand and ninety-four women with adnexal mass were included. Patients were divided into three groups according to clinical complaints: asymptomatic (group A), patients with symptoms non-suspicious of ovarian cancer (group B) and patients with symptoms suspicious of ovarian cancer (group C).

Diagnostic performance of transvaginal gray-scale ultrasound for specific diagnosis of benign ovarian cysts in relation to menopausal status.

In this study we aimed to assess the diagnostic accuracy of transvaginal ultrasound for assigning a specific diagnosis to benign adnexal masses in pre- and postmenopausal women. The study comprised 2146 adnexal masses in 1980 women. 1420 women were premenopausal and 560 were postmenopausal.

Transvaginal color Doppler imaging in the detection of ovarian cancer in a large study population.

Introduction: The aim of the study was to compare the diagnostic accuracy of grayscale sonography and that of color Doppler imaging in the diagnosis of ovarian malignancy in a prospective study by the Sardinia-Navarra group.

Methods: The study was performed as a collaborative work at the 2 European university departments of obstetrics and gynecology between 1997 and 2007. A total of 2148 pelvic masses in 1997 women on whom transvaginal sonography were performed before surgical exploration were included in the study.

Triage for surgical management of ovarian tumors in asymptomatic women: assessment of an ultrasound-based scoring system.

Objectives: To prospectively evaluate an ultrasound-based scoring system as a method for triaging asymptomatic women presenting with an adnexal mass for surgical treatment.

Methods: Two hundred and four adnexal masses in 189 asymptomatic women undergoing elective surgical treatment at our institution were included in this prospective study. Patients were evaluated by transvaginal power Doppler ultrasound imaging before surgery.

A new scoring system to differentiate benign from malignant adnexal masses.

Objective: The purpose of this study was to develop and cross-validate a new sonographic scoring system for differentiation between benign and malignant adnexal masses.

Study Design: This study was conducted in a tertiary care university hospital. In the first part of the study, we used a multivariate logistic regression analysis to develop a scoring system that was based on morphologic and Doppler sonographic data for 705 adnexal masses in 665 patients who were diagnosed and treated at our institution from January 1995 to June 2001.

Assessment of a new logistic model in the preoperative evaluation of adnexal masses.

Objective: To assess a new logistic regression model developed to predict malignancy in adnexal masses.

Methods: In the first part of this study, we developed a logistic model by applying logistic regression analysis in a series of 268 adnexal masses (203 benign and 65 malignant lesions) in 248 patients (mean age, 43.6 years; SD, 14.

[Surgical options in the treatment of polycystic ovary syndrome].

Since it was defined, SOP has been related to surgery. Before clomifero was introduced, ovarian wedge resection was the only way to stimulate ovulation and gestation in women with this syndrome. Surgical techniques were derelict in favour of less aggressive medical treatments.

In vivo validation of the time domain velocity measurement technique of blood flow in human fetuses.

Time domain ultrasonography is an alternative to Doppler analysis of blood flow direction and velocity. The time domain technique uses timing information between successive echo pulses to measure flow velocities directly through a color display map. This study was undertaken to validate this technique for measuring peak systolic velocity compared to the pulsed-wave Doppler method in human fetuses.

The role of transvaginal ultrasonography combined with color velocity imaging and pulsed Doppler in the diagnosis of endometrioma.

Objective: To assess the diagnostic accuracy of transvaginal ultrasonography alone and combined with color velocity imaging and pulsed Doppler in differentiating ovarian endometriomas from other nonendometriotic masses.

Design: Prospective study with pathological confirmation of sonographic diagnosis.

Setting: Department of Obstetrics and Gynecology at a university hospital.

Corpus luteum blood flow in abnormal early pregnancy.

Thirty-eight consecutive patients with the diagnosis of abnormal early singleton pregnancy were studied with transvaginal color velocity imaging and pulsed Doppler ultrasonography to assess corpus luteum blood flow. Mean gestational age was 8.5 weeks (range, 6 to 12 weeks).

Comparative study of transvaginal ultrasonography and hysteroscopy in postmenopausal bleeding.

Twenty-eight women with postmenopausal bleeding were retrospectively studied to assess the accuracy of transvaginal sonography (TVS) and hysteroscopy for diagnosing endometrial pathology. TVS was performed in all patients. Considering a cutoff value of < or = 5 mm as normal, TVS showed normal findings in 14 patients (50%) and suggested endometrial abnormalities in other 14 (50%).

Assessment of luteal blood flow in normal early pregnancy.

A cross-sectional study was performed in 85 low-risk singleton first trimester pregnancies to assess corpus luteum blood flow during this period. Gestational age, established by measuring crown-rump length, ranged from 6 to 12 weeks. All cases were studied by transvaginal color velocity imaging and pulsed Doppler ultrasonography.

The reliability of transvaginal ultrasonography to detect retained tissue after spontaneous first-trimester abortion, clinically thought to be complete.

In order to assess the reliability of transvaginal ultrasonography for the detection of trophoblastic tissue retained after spontaneous first-trimester abortion and clinically thought to be complete, the clinical, sonographic and pathological data of 33 women were retrospectively analyzed. The patients' mean age was 34 years (range 24-48). The mean gestational age at presentation of symptoms was 8 weeks (range 5.

Granular cell tumor of vulva on episiotomy scar.

The granular cell tumor (GCT) is a rare neoplasm derived from Schwann cells and is considered to be a benign tumor. The vulvar region is one of the common sites for these lesions. Vulvar occurrence of GCT constitutes about 7% of cases.

[Development of utero-chorionic vascular resistance in early pregnancy].

The physiologic evolution of the utero-chorionic vascular resistances during the first trimester of pregnancy is described. With the use of pulsed Doppler, 25 normal pregnancies were followed weekly, performing 288 scans between the 6th and the 12th weeks of pregnancy. The detection of the FVW was done at the level of the uterine and retro-chorionic vessels.
