Hormonal contraceptives and breast cancer: Clinical data.
2018
Abstract The endocrine background of breast cancer has raised questions about the increase in risk that might bear the use of hormonal contraceptives. This has been a particular issue in the case of young women, who constitute the population of contraceptive consumers. Observational studies have been the main source of evidence, which has mainly limited to the combined estrogen-progestogen preparations, the popular pill. Studies in the 80′s and 90′s of the past century found a small, around a 20%, increase in risk. The translation in absolute number of excess cases has been exiguous because the prevalence of the disease is relatively small in premenopausal women. Moreover, the risk slowly s…
Integrated pre-surgical diagnostic algorithm to define extent of disease in cervical cancer
2020
ObjectivesSurvival of patients with cervical cancer is strongly associated with the local extent of the primary disease. The aim of the study was to develop an integrated diagnostic algorithm, including ultrasonography (USG), magnetic resonance imaging (MRI), and examination under anesthesia, to define the local extent of disease in patients with newly diagnosed cervical cancer.MethodsPatients with biopsy proven cervical cancer who underwent primary surgery from January 2013 to December 2018 in four participating centers were recruited. Patients who underwent USG, MRI, and examination under anesthesia prior to surgery were included in the study. Those for whom complete data were not availab…
Validity of the Colposcopic Criteria Inner Border Sign, Ridge Sign, and Rag Sign for Detection of High-Grade Cervical Intraepithelial Neoplasia
2013
OBJECTIVE: To evaluate the association of three patho-gnomonic criteria, inner border, ridge sign, and rag sign with high-grade cervical intraepithelial neoplasia (CIN) using video exoscopy. METHODS: Retrospective evaluation of video recordings of 335 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and, if indicated loop excisions, was performed. The most severe histologic diagnosis was recorded. Sensitivity, specificity, positive, negative predictive value, and likelihood ratios for highgrade CIN were calculated. RESULTS: In 285 patients (85%), a single colposcopy directed biopsy was taken; 50 patients (15%) underwent two biopsies. One hundred sixty-two patie…
Laparoscopic Radical Hysterectomy After Concomitant Chemoradiation in Locally Advanced Cervical Cancer: A Prospective Phase II Study
2015
Abstract Study Objective To assess the feasibility of total robotic radical surgery (TRRS) in patients with locally advanced cervical cancer (LACC) who receive chemoradiation therapy (CT/RT). Design A prospective (preplanned) study of a nonrandomized controlled trial (Canadian Task Force classification level 2). Setting Catholic University of the Sacred Hearth, Rome, Italy. Patients Between September 2013 and January 2016, a total of 40 patients with LACC (Federation Internationale de Gynecologie et d'Obstetrique stage IB2–III) were enrolled in the study. Interventions Robotic radical hysterectomy (RRH) plus pelvic and/or aortic lymphadenectomy was attempted within 6 weeks after CT/RT. The …
Vesico-uterine fistula treated by amenorrhoea induced with contraceptive steroids. Two case reports.
1980
2 case reports of women with vesico-uterine fistulae who were successfully treated by inducing amenorrhea by the continuous administration of an estrogen-progestogen compound for 6 months are presented. Ortho-Novum 1/50 was used. The amenorrheic condition induced by continuous ingestion of an oral contraceptive agent allowed the fistula time to heal since fistulae rarely close spontaneously because of fluids flowing fhrough them inhibiting the healing process. This method of management should be tried before surgery the generally recommended treatment.
Dopamine receptor 2 activation inhibits ovarian vascular endothelial growth factor secretion in vitro: implications for treatment of ovarian hypersti…
2013
Objective To ascertain whether vascular endothelial growth factor (VEGF) secretion by luteinized granulosa cells (GCs) is modulated by the dopaminergic system in a dose-dependent fashion and how this is related to the differential efficacy of dopamine receptor 2 (D2)-agonists (D2-ag) in preventing ovarian hyperstimulation syndrome (OHSS). Design The relationship between the dopaminergic system and VEGF secretion in luteinized GCs was evaluated. Archived human ovaries were immunostained to characterize D2 expression. Setting University affiliated infertility center. Patient(s) Premenopausal women and egg donors. Intervention(s) Luteinized GCs were cultured with the D2-ag cabergoline. Human o…
MicroRNA expression profile in endometriosis: its relation to angiogenesis and fibrinolytic factors
2014
Study question Could an aberrant microRNA (miRNA) expression profile be responsible for the changes in the angiogenic and fibrinolytic states observed in endometriotic lesions? Summary answer This study revealed characteristic miRNA expression profiles associated with endometriosis in endometrial tissue and endometriotic lesions from the same patient and their correlation with the most important angiogenic and fibrinolytic factors. WHAT IS ALREADY KNOWN?: An important role for dysregulated miRNA expression in the pathogenesis of endometriosis is well documented. However, to the best of our knowledge, there are no reports of the relationship between angiogenic and fibrinolytic factors and mi…
A first-in-human study of PDC31 (prostaglandin F2 receptor inhibitor) in primary dysmenorrhea
2014
What is the safe and pharmacodynamically active dose range for PDC31 (prostaglandin F2α receptor inhibitor) in patients with primary dysmenorrhea (PD)?The 1 mg/kg/h dose of PDC31 appears to be safe and potentially effective in reducing intrauterine pressure (IUP) and pain associated with excessive uterine contractility when given as a 3-h infusion in patients with PD.PDC31 has previously been shown to reduce the duration and strength of PGF2α-induced contractions in human uterine myometrial strip models and to delay delivery in animal models of preterm labor.This was a prospective, multi-center, dose-escalating first-in-human Phase I study conducted from March 2011 to June 2012. A total of …
Myofibroblasts Are Evidence of Chronic Tissue Microtrauma at the Endometrial-Myometrial Junctional Zone in Uteri With Adenomyosis.
2017
Background Adenomyosis (AM) uteri exhibit hyperperistalsis. The latter causes a chronic tissue trauma at the endometrial-myometrial junctional zone (EMJZ). Upon tissue trauma, microdehiscences in the myometrium facilitate the translocation of basal endometrial fragments into the myometrium. There, a metaplasia (mediated by transforming growth factor β1 [TGFβ1] and connective tissue growth factor [CTGF]) occurs and AM lesions develop. The abundance of myofibroblasts in a tissue hallmarks metaplasia and points to a tissue microtrauma. Materials and methods To study if myofibroblasts-as an evidence of tissue microtrauma-are more abundant at EMJZ in AM-uteri, a case-control experimental study w…
A 20-year follow-up of young women with polycystic ovary syndrome.
2012
OBJECTIVE: To determine whether hormonal, metabolic, and anthropomorphic parameters change over 20 years in women with polycystic ovary syndrome (PCOS). METHODS: One hundred ninety-three women with PCOS, aged 20–25 years, were diagnosed according to Rotterdam criteria, divided into four phenotypes (A–D), and followed at 5-year intervals for 20 years. Androgens, gonadotropins, insulin, glucose, body mass index, waist circumference, and ovarian volume were measured. RESULTS: At diagnosis, 57% had classic features (phenotype A), 9% had classic features without ovarian findings (phenotype B), 26% had the ovulatory phenotype (C), and 7% were nonhyperandrogenic (D). After 10 years, androgens decr…
