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(More)
OBJECTIVE The goal of this study was to determine the toxicity patterns and clinical usefulness of intraoperative electron beam radiotherapy (IOERT) in patients with unfavorable-outcome cervical cancer. METHODS From January 1986 to June 1999, 67 patients (36 recurrent, 31 primary disease) were treated with IOERT. Previously unirradiated patients received(More)
OBJECTIVE The purpose of this study was to evaluate the role of 3-dimensional power Doppler angiography (3D-PDA) to discriminate between benign and malignant endometrial disease in women with postmenopausal bleeding and thickened endometrium. STUDY DESIGN Ninety-nine postmenopausal women (median age, 63.1 years; range, 48-84 years) with uterine bleeding(More)
Specificity of two widespread Trypanosoma cruzi clonal genotypes or "clonets" (20 and 39) was first analyzed by hybridization with a large set of T. cruzi stocks characterized by multigenic study relying on both MLEE and RAPD. Then, these clonets were detected in the blood of Chagasic children from a Bolivian endemic area by a combination of polymerase(More)
BACKGROUND The aim of this investigation was to correlate ovarian endometrioma vascularization with the presence of pelvic pain. METHODS The presence of blood flow, peak systolic velocity (PSV, cm/s) and lowest pulsatility index (PI), assessed by transvaginal colour Doppler ultrasonography and CA-125 plasma concentrations, were retrospectively analysed in(More)
OBJECTIVE To compare the diagnostic accuracy of gray scale sonography and color Doppler imaging in the differential diagnosis of adnexal malignancies from benign complex pelvic masses in a multicenter prospective study. METHODS The study was performed as a collaborative work at 3 European university departments of obstetrics and gynecology. A total of 826(More)
In the present study we aimed to develop a formula for predicting adnexal malignancy based on menopausal status, ultrasound morphology, and color Doppler findings. Logistic regression analysis was performed retrospectively in 79 adnexal masses (59 benign and 20 malignant) in 73 unselected and consecutive patients. All these masses had been preoperatively(More)
PURPOSE To describe and analyze the diagnostic performance of uterine virtual navigation with three-dimensional (3D) ultrasonography (US) for the assessment of the depth of myometrial infiltration by endometrial cancer. MATERIALS AND METHODS Institutional review board approval was obtained; patients gave oral informed consent. Women with endometrial(More)
OBJECTIVE The purpose of this study was to assess whether endometrial volume (EV) and 3-dimensional (3D) power Doppler indices can discriminate between hyperplasia and endometrial carcinoma and can predict extension of the endometrial carcinoma. METHODS Eighty-four women with uterine bleeding and a histopathologic diagnosis of endometrial hyperplasia (n =(More)
OBJECTIVE To determine the diagnostic performance of International Ovarian Tumor Analysis (IOTA) 'simple' rules for discriminating between benign and malignant adnexal masses. METHODS A prospective study was performed between January 2011 and June 2012. Eligible patients were women diagnosed with a persistent adnexal mass who presented to the(More)
