Is Hysteroscopy Better than Ultrasonography for Uterine Cavity Evaluation? An Evidence-Based and Patient-Oriented Approach
2016
Evaluation of the uterine cavity is an important part of the gynecological check, especially in symptomatic women and, over the last few decades, a number of technical and technological advancements has allowed a superb investigation of this organ. Traditionally, transvaginal ultrasound (TVUS) has been the first-line diagnostic tool for evaluating uterine diseases, also considering that gynecologists are familiar with the technique since it is included in the basic training in obstetrics and gynecology. Nevertheless, to date “office hysteroscopy” received growing attention since the development of smaller-diameter hysteroscopes which has made it possible to easily perform the hysteroscopy …
Efectos del tratamiento con agonistas dopaminérgicos sobre las lesiones endometriósicas
2014
La prolactina (PRL) es una hormona hipofisaria que desempeña un papel fundamental en diversas funciones reproductivas, fundamentalmente en la lactancia. En situaciones patológicas que están relacionadas con la presencia de adenomas hipofisarios o ingesta de fármacos psicotropos, los niveles de PRL están elevados y afectan a la función gonadal, pues inhiben la secreción de hormonas hipofisarias como la LH o FSH, ocasionando amenorrea (9%), galactorrea (25%) o ambas (70%) (1).La hiperprolactinemia, por lo tanto, es una causa frecuente de infertilidad por anovulación (2). Por otro lado, la endometriosis es una importante entidad patológica ginecológica estrógeno dependiente cuya prevalencia en…
Renal endometriosis mimicking complicated cysts of kidney: report of two cases
2017
Endometriosis is a common gynecologic disorder characterized by ectopic endometrial tissue growth outside the uterine cavity. Although usually occurring in pelvic organs, endometrial lesions may involve urinary tract. Renal endometriosis is extremely rare and it has only occasionally been reported in the past. We report two cases of patients with renal cystic lesions, incidentally found at imaging techniques during oncologic follow-up for gastric sarcoma and melanoma, initially misinterpreted as complicated haemorrhagic cysts and then histologically characterized as renal localizations of extragenital endometriosis.
Comparative study of molecular processes and factors affecting endometrial function in subfertile patients with uterine disorders
2021
El endometrio humano es un tejido dinámico y complejo que solo es receptivo al embrión durante un corto periodo de tiempo. Por lo tanto, la identificación de trastornos y factores que impidan que el endometrio adquiera un fenotipo receptivo es crucial para poder prevenir fallos de implantación embrionaria y aumentar las tasas de embarazo. Los trastornos uterinos son complejos, multifactoriales y poligénicos y a menudo comprometen la fertilidad femenina, aunque se desconoce con exactitud cómo afectan a la adquisición de la receptividad endometrial. Además, estos trastornos carecen actualmente de un tratamiento efectivo, a menudo presentan comorbilidad entre ellos y su incidencia aumenta con …
Gamete intrafallopian transfer in the treatment of infertility: the first series at the University of Palermo
1986
Twenty-six couples with unexplained infertility (UI), nine women with repeated failures of artificial insemination with donor semen (AID), three women with mild endometriosis, three with periadnexal adhesions, one with hostile (not immunologic) cervical mucus, and one couple in which the male partner was affected by asthenospermia were treated by the gamete intrafallopian transfer (GIFT) technique. Three different protocols for controlled ovarian hyperstimulation were used, and an adequate follicular growth and oocyte maturation were achieved in all cases. Seventeen pregnancies were obtained, for a global pregnancy rate of 38.6%. Two pregnancies (11.7%) ended in clinical abortions, and one …
Environment and Endometriosis: A toxic relationship
2015
Endometriosis is a common, be- nign, estrogen-dependent gynecological dis- ease that represents one of the main causes of hospitalization in industrialized countries. It is well established that a large amount of natural and man-made chemicals are present in the en- vironment and both humans and animals are exposed to them. Dioxin and dioxin-like com- pounds have long biological half-life, can accu- mulate within the organism and could negative- ly affect several physiological processes. The purpose of this review is to provide an overview of the possible relationship between these chemicals and the pathogenesis of en- dometriosis.
Stem Cells and the Endometrium: From the Discovery of Adult Stem Cells to Pre-Clinical Models.
2021
Adult stem cells (ASCs) were long suspected to exist in the endometrium. Indeed, several types of endometrial ASCs were identified in rodents and humans through diverse isolation and characterization techniques. Putative stromal and epithelial stem cell niches were identified in murine models using label-retention techniques. In humans, functional methods (clonogenicity, long-term culture, and multi-lineage differentiation assays) and stem cell markers (CD146, SUSD2/W5C5, LGR5, NTPDase2, SSEA-1, or N-cadherin) facilitated the identification of three main types of endogenous endometrial ASCs: stromal, epithelial progenitor, and endothelial stem cells. Further, exogenous populations of stem c…
Immunohistochemical characterization of endometriosis-associated smooth muscle cells in human peritoneal endometriotic lesions
2011
Background Smooth muscle cells (SMC) are common components of endometriotic lesions. SMC have been characterized previously in peritoneal, ovarian and deep infiltrating endometriotic lesions and adenomyosis. The aim of this retrospective study was to investigate the extent of differentiation in endometriosis-associated SMC (EMaSMC) in peritoneal endometriotic lesions. Methods We obtained biopsies from peritoneal endometriotic lesions (n = 60) and peritoneal sites distant from the endometriotic lesion (n = 60), as well as healthy peritoneum from patients without endometriosis (control tissue, n = 10). These controls were hysterectomy specimens from patients without endometriosis or adenomyos…
Surgical Neuropelviology: Combined Sacral Plexus Neurolysis and Laparoscopic Laterally Extended Endopelvic Resection in Deep Lateral Pelvic Endometri…
2020
ABSTRACT Objective Surgical demonstration of combined sacral plexus neurolysis and laparoscopic laterally extended endopelvic resection for deep lateral infiltrating endometriosis. Design Video showing principles of neurolysis and laparoscopic laterally extended endopelvic resection applied to endometriotic surgery. Setting University tertiary referral center. Deep infiltrating endometriosis is an underestimated disease with real medical and clinical issues, recently classified as central pelvic endometriosis and lateral pelvic endometriosis further divided into superficial and deep according to the structures’ involvement [1] . The surgical removal of endometriotic foci remains the standar…
Inhibition of KIF20A by BKS0349 reduces endometriotic lesions in a xenograft mouse model
2019
AbstractSeveral studies have suggested a possible etiological association between ovarian endometriosis and ovarian cancer. Evidence has shown that KIF20A overexpression might confer a malignant phenotype to ovarian tumors by promoting proliferation and inhibiting apoptosis. However, no data about the role of KIF20A in endometriosis have been described. In this study, the human endometrium (n = 4) was transfected by mCherry adenovirus and intraperitoneally implanted in mice. Subsequently, mice were divided in three groups (n = 8/group) that were treated with Vehicle, BKS0349 (KIF20A-antagonist) or cabergoline (dopamine receptor agonist) for 21 days. mCherry-labeled endometriotic lesions wer…
