Reproductive outcomes after vaginal repair of isthmocele: A preliminary study and systematic review of the literature. Eur J Obstet Gynecol Reprod Biol 2024; 296:163-169. [PMID: 38447278 DOI: 10.1016/j.ejogrb.2024.02.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/06/2024] [Accepted: 02/11/2024] [Indexed: 03/08/2024]
Abstract
OBJECTIVE Although vaginal repair of isthmocele is an effective and safe surgical option, data on reproductive and obstetrical outcomes are lacking. The aim of this study is to evaluate reproductive outcomes of women undergone vaginal repair of isthmocele. We also systematically reviewed the existent literature to offer a general view of available data. STUDY DESIGN Retrospective analysis of a database prospectively collected between January 2018 and January 2022 at San Raffaele Hospital, Milan, Italy. We included secondary infertile women with ultrasound documented isthmocele who undergone vaginal repair. Post-surgical clinical, reproductive and obstetric outcomes were recorded. An advanced systematic search of the literature up to January 2023 was conducted. RESULTS 17 women were included. The mean age of the included patients was 37.2 ± 2.7 years. The median of previous caesarian sections was 1 (1-2). One intra-operative complication (5.9 %) was reported (bladder injury, repaired at the time of surgery). At follow up, bleeding was successfully treated in 8 women (8/10; 80 %). Pregnancy was obtained in 7 women (7/17; 41.2 %): the conception was spontaneous in 4 women (4/7; 57.1 %) and trough assisted reproductive technology in 3 patients (3/7; 42.9 %). The mean time from surgery to pregnancy was 10.8 (±6.7) months. One spontaneous abortion was reported (1/7; 14.3 %), while live birth was achieved in 6 pregnancies (6/7; 85.7 %). All deliveries were by caesarian section at a median gestational age of 37.5 (36-38.25) weeks. No obstetrical complications were reported. At the time of caesarean section, no defects on the lower segment were retrieved. Regarding the systematic research, among the 21 studies screened, only 4 articles were included in the review. Pregnancy rate was around 60-70 % with very few obstetrical complications (0.01 %) such as abnormal placentation or preterm birth. CONCLUSIONS Vaginal repair of isthmocele is a minimally invasive, safe and effective surgical approach in terms of postsurgical residual myometrium tichness. Systematic review to date has found low-quality evidences on the impact of vaginal surgery in the management of secondary infertility and obstetrics outcomes in women with isthmocele.

Extracellular vesicles secreted by human aneuploid embryos present a distinct transcriptomic profile and upregulate MUC1 transcription in decidualised endometrial stromal cells. Hum Reprod Open 2024; 2024:hoae014. [PMID: 38559895 PMCID: PMC10980593 DOI: 10.1093/hropen/hoae014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 02/06/2024] [Indexed: 04/04/2024] Open
Abstract
STUDY QUESTION Do extracellular vesicles (EVs) secreted by aneuploid human embryos possess a unique transcriptomic profile that elicits a relevant transcriptomic response in decidualized primary endometrial stromal cells (dESCs)? SUMMARY ANSWER Aneuploid embryo-derived EVs contain transcripts of PPM1J, LINC00561, ANKRD34C, and TMED10 with differential abundance from euploid embryo-derived EVs and induce upregulation of MUC1 transcript in dESCs. WHAT IS KNOWN ALREADY We have previously reported that IVF embryos secrete EVs that can be internalized by ESCs, conceptualizing that successful implantation to the endometrium is facilitated by EVs. Whether these EVs may additionally serve as biomarkers of ploidy status is unknown. STUDY DESIGN SIZE DURATION Embryos destined for biopsy for preimplantation genetic testing for aneuploidy (PGT-A) were grown under standard conditions. Spent media (30 μl) were collected from euploid (n = 175) and aneuploid (n = 140) embryos at cleavage (Days 1-3) stage and from euploid (n = 187) and aneuploid (n = 142) embryos at blastocyst (Days 3-5) stage. Media samples from n = 35 cleavage-stage embryos were pooled in order to obtain five euploid and four aneuploid pools. Similarly, media samples from blastocysts were pooled to create one euploid and one aneuploid pool. ESCs were obtained from five women undergoing diagnostic laparoscopy. PARTICIPANTS/MATERIALS SETTING METHODS EVs were isolated from pools of media by differential centrifugation and EV-RNA sequencing was performed following a single-cell approach that circumvents RNA extraction. ESCs were decidualized (estradiol: 10 nM, progesterone: 1 µM, cAMP: 0.5 mM twice every 48 h) and incubated for 24 h with EVs (50 ng/ml). RNA sequencing was performed on ESCs. MAIN RESULTS AND THE ROLE OF CHANCE Aneuploid cleavage stage embryos secreted EVs that were less abundant in RNA fragments originating from the genes PPM1J (log2fc = -5.13, P = 0.011), LINC00561 (log2fc = -7.87, P = 0.010), and ANKRD34C (log2fc = -7.30, P = 0.017) and more abundant in TMED10 (log2fc = 1.63, P = 0.025) compared to EVs of euploid embryos. Decidualization per se induced downregulation of MUC1 (log2fc = -0.54, P = 0.0028) in ESCs as a prerequisite for the establishment of receptive endometrium. The expression of MUC1 transcript in decidualized ESCs was significantly increased following treatment with aneuploid compared to euploid embryo-secreted EVs (log2fc = 0.85, P = 0.0201). LARGE SCALE DATA Raw data have been uploaded to GEO (accession number GSE234338). LIMITATIONS REASONS FOR CAUTION The findings of the study will require validation utilizing a second cohort of EV samples. WIDER IMPLICATIONS OF THE FINDINGS The discovery that the transcriptomic profile of EVs secreted from aneuploid cleavage stage embryos differs from that of euploid embryos supports the possibility to develop a non-invasive methodology for PGT-A. The upregulation of MUC1 in dESCs following aneuploid embryo EV treatment proposes a new mechanism underlying implantation failure. STUDY FUNDING/COMPETING INTERESTS The study was supported by a Marie Skłodowska-Curie Actions fellowship awarded to SM by the European Commission (CERVINO grant agreement ID: 79620) and by a BIRTH research grant from Theramex HQ UK Ltd.

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach. J Minim Invasive Gynecol 2023; 30:616-626. [PMID: 37001691 DOI: 10.1016/j.jmig.2023.03.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 03/23/2023] [Accepted: 03/24/2023] [Indexed: 04/03/2023]
Abstract
The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice.

Minimally invasive surgery for ovarian endometriosis as a mean of improving fertility: Cystectomy vs. CO2 fiber laser ablation what do we know so far? Front Surg 2023; 10:1147877. [PMID: 37051570 PMCID: PMC10083313 DOI: 10.3389/fsurg.2023.1147877] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 03/10/2023] [Indexed: 03/29/2023] Open
Abstract
Minimally invasive surgery emerged in the 1980s as a safe and effective technique which requires smaller incisions and, usually, a shorter hospital stay compared to traditional surgery. Since then, minimally invasive surgery has expanded in many surgical specialties. One of its newest application in gynecology stands in the infertility management of young women with unexplained infertility or suspected endometriosis. In these cases, laparoscopy allows to diagnose and treat the disease aiming to increase at best the chances of spontaneous pregnancy or trough assisted reproductive technology. Nowadays, minimally invasive surgical approach of ovarian endometriosis consists of either laparoscopic cystectomy or ablative techniques such as laparoscopic CO2 fiber laser vaporization. Although cystectomy represents the gold standard according to the latest Cochrane review, some endometriosis experts are worried about its detrimental effect on healthy ovarian parenchyma and suggest preferring a less aggressive approach such as CO2 fiber laser vaporization. The aim of this review is to give an overview of the available evidences about the impact of the two surgical procedures on ovarian reserve markers and pregnancy outcome.

Abstract
BACKGROUND Infertile women carrying ovarian endometriomas can be managed either with surgery or by in vitro fertilization (IVF). The objective of this study is to compare ovarian responsiveness to controlled ovarian stimulation (COS) in assisted reproduction techniques (ART) in infertile women carrying small intact endometriomas and those managed by endometrioma cystectomy or CO2 fiber laser ablation. METHODS Retrospective case-control study of prospectively collected data including women underwent ART for endometriosis-related infertility. The study group consisted of infertile women undergoing endometriomas CO2 fiber laser vaporization before ART ('ART after laser CO2' group). Controls were infertile women with endometrioma managed by cystectomy before ART ('ART after cystectomy' group) and infertile women with small endometriomas undergoing ART as first approach ('ART only' group). RESULTS Of the 86 included patients, 27 (31.4%) belonged to 'ART after laser CO2' group, 37 (43%) to 'ART after cystectomy' group and 22 (25.6%) to 'ART only' group. Surgical groups had larger endometriomas than patients referred to 'ART only' group. No between-groups differences were observed in terms of COS protocol, gonadotropins starting and total doses and length of COS. While women belonged to 'ART after cystectomy' group had fewer recruited follicles (p = .014), oocytes (p = .042), MII oocytes (p = .042) and formed embryos (p = .004) compared to women of 'ART only' group, no significant differences were found between patients of 'ART only' group 'ART after laser CO2' group. A greater number of good-quality embryos were observed in surgical groups. No between-groups differences were found in clinical pregnancy rates. CONCLUSIONS Our results demonstrate encouraging findings on IVF/ICSI outcomes after laser CO2 endometrioma ablation in terms of both quantity and quality of developed embryos.

Fertility Sparing Procedure using Carbon Dioxide Fiber Laser Vaporization of Ovarian Endometrioma. JOURNAL OF VISUALIZED EXPERIMENTS : JOVE 2022.

Abstract
The surgical management of endometrioma is still a matter of debate. Cystectomy, which is recognized as the standard technique, seems to be associated with a potential reduction in the ovarian reserve due to the inadvertent removal and thermal damage of healthy ovarian tissue. New ablative techniques with reduced tissue penetration depth and less thermal spread to the surrounding parenchyma may represent a viable alternative to cystectomy. For these reasons, the aim of this manuscript is to demonstrate the ablation of the endometrioma capsule using a CO2 fiber laser technique and discuss the clinical outcomes. Once the cyst has been drained and washed, a biopsy is taken. After cyst eversion, vaporization of the inner surface of the cyst is performed using a CO2 fiber laser. The technique is simple and reproducible as even young surgeons without any surgical experience were more confident in performing laser CO2 vaporization instead of cystectomy. The positive effects of CO2 technology are reported in a randomized controlled trial, where the postoperative changes in the antral follicular count (AFC) and antimullerian hormone (AMH) levels were compared between patients who had their endometrioma excised (cystectomy) and those who had undergone endometrioma vaporization with CO2 laser. The patients treated with CO2 laser showed significantly increased AFC without a reduction in serum AMH levels as compared to the cystectomy group, in which both parameters were significantly reduced. The postoperative pregnancy rate was also assessed, and comparable pregnancy rates were found after both treatments. On the contrary, patients treated with the CO2 fiber laser technique had more favorable in-vitro fertilization (IVF) outcomes compared to cystectomy. In conclusion, the CO2 fiber laser technique may represent a viable alternative to cystectomy in the surgical treatment of endometrioma in terms of ovarian preservation, pregnancy rates, and IVF outcomes. Moreover, it has the advantage of being independent of the surgeon's skills and personal experience.

Abstract
Abstract
Study question
Could EVs secreted by aneuploid embryos a) serve for development of RNA biomarkers for PGT-A and b) elicit a relevant transcriptomic response in decidualised ESCs?
Summary answer
Aneuploid embryo EVs a) contain PPM1J, LINC00561, ANKRD34C and TMED10 in differential abundance from euploid EVs and b) induce up-regulation of MUC1 in decidualised ESCs.
What is known already
Embryo aneuploidy accounts for approximately 50% of all recurrent implantation failures in women >35 years old. PGT-A identifies euploid embryos to increase implantation probability but the technology is controversial as it requires an invasive embryo biopsy with an elusive long-term biosafety. The development of non-invasive methods to screen out aneuploid embryos is paramount. It is also critical to decode the embryo-endometrial dialog underlying implantation failure. We have previously reported that IVF embryos secrete EVs that can be internalised by ESCs, conceptualising that successful implantation to the endometrium is facilitated by EVs, which may additionally serve as biomarkers of ploidy status.
Study design, size, duration
Embryos destined for biopsy on days 5-7 for PGT-A were grown under standard conditions. Spent media (30μl) were collected from euploid (n = 175) and aneuploid embryos (n = 145) at both cleavage (days 1-3) and blastocyst (days 3-5) stage. Media samples from n = 35 cleavage embryos were pooled in order to obtain five euploid and four aneuploidy pools. Blastocyst media were pooled to create one euploid and one aneuploid pool. ESCs were obtained from five women undergoing diagnostic laparoscopy.
Participants/materials, setting, methods
The study was realised at a research hospital. EVs were isolated from euploid and aneuploid Day3 pools with differential ultracentrifugation and EV-RNA sequencing was performed following the SMARTer Stranded Total RNA-Seq approach. ESCs were decidualised (E2:10nM, P4:1uM, cAMP:0.5 mM twice every 48 hours) and treated for 24 hours with 50 ng/ml euploid or aneuploid EVs extracted from blastocyst media. RNA sequencing was performed on ESCs following the Truseq RNAseq protocol.
Main results and the role of chance
Aneuploid cleavage stage embryos (n = 4) secreted EVs that were less abundant in RNA fragments originating from the genes PPM1J (log2fc=-5.13, p = 0.011), LINC00561 (log2fc=-7.87, p = 0.010) and ANKRD34C (log2fc=-7.30, p = 0.017) and more abundant in TMED10 (log2fc=1.63 p = 0.025) compared to EVs (n = 5) from euploid embryos. Decidualisation per se induced downregulation of MUC1 (log2FC=-0.54, p = 0.0028) in ESCs as prerequisite for the establishment of receptive endometrium. The expression of MUC1 transcript in decidualised ESCs was significantly increased following treatment with aneuploid compared to euploid embryo-secreted EVs (log2FC=0.85, p = 0.0201).
Limitations, reasons for caution
The findings of the study may require validation utilising a second cohort of EVs samples.
Wider implications of the findings
This discovery that the RNA cargo of EVs secreted from aneuploid cleavage stage embryos is diverse from that of euploid embryos potentiates the development of non-invasive methodology for PGT-A. The upregulation of MUC1 in decidualised ESCs following aneuploid embryo EV treatment proposes a new mechanism underlying implantation failure.

P–606 A second stimulation in the same ovarian cycle rescues advanced-maternal-age patients obtaining ≤ 3 blastocysts after the conventional approach by preventing treatment-discontinuation. Hum Reprod 2021.

Abstract
Abstract
Study question
Is double stimulation in the same ovarian cycle (DuoStim) a valuable strategy to rescue advanced-maternal-age patients obtaining ≤ 3 blastocysts for chromosomal-testing after conventional stimulation?
Summary answer
DuoStim is effective to prevent treatment discontinuation thereby increasing the 1-year cumulative-live-birth-rate among advanced-maternal-age patients obtaining 0–3 blastocysts after a first conventional stimulation.
What is known already
Folliculogenesis is characterized by continuous waves of follicular growth. DuoStim approach exploits these dynamics to conduct two stimulations in a single ovarian cycle and improve the prognosis of advanced-maternal-age and/or reduced-ovarian-reserve women. Independent groups worldwide successfully adopted DuoStim with various regimens reporting similar oocyte/embryo competence after both stimulations. Recently, we have demonstrated the fruitful adoption of DuoStim in patients fulfilling the Bologna criteria, especially because of the prevention of treatment discontinuation. Here we aimed at investigating whether DuoStim can be adopted to rescue poor prognosis patients obtaining 0–3 blastocysts after the conventional approach.
Study design, size, duration
Proof-of-concept matched case-control study. All patients obtaining 0–3 blastocysts after conventional-stimulation between 2015–2018 were proposed DuoStim. The 143 couples who accepted were matched for maternal age, sperm factor, cumulus-oocyte-complexes and blastocysts obtained after the first stimulation to 143 couples who did not. The primary outcome was the 1-year cumulative-live-birth-rate. If not delivering, the control group had 1 year to undergo a second attempt with conventional-stimulation. All treatments were concluded (live-birth achieved or no euploid left).
Participants/materials, setting, methods
Only GnRH-antagonist with recombinant-gonadotrophins and agonist trigger stimulation protocols were adopted. All cycles entailed ICSI with ejaculated sperm, blastocyst culture, trophectoderm biopsy, comprehensive-chromosome-testing and vitrified-warmed euploid single-embryo-transfer(s). Cumulative-live-birth-rate was calculated per patient considering both stimulations in the same ovarian cycle (DuoStim group) or up to two stimulations in 1 year (control group). Treatment discontinuation rate in the control group was calculated as patients who did not return for a second stimulation among non-pregnant ones.
Main results and the role of chance
Among the 286 couples included (41.0±2.9yr;4.9±3.1 cumulus-oocytes-complexes and 0.8±0.9 blastocysts), 126 (63 per group), 98 (49 per group), 52 (26 per group) and 10 (5 per group) obtained 0,1,2 and 3 blastocysts after the first stimulation, respectively. The cumulative-live-birth-rate was 9% in the control group after the first attempt (N = 13/143). Among the 130 non-pregnant patients, only 12 returned within 1-year (165±95days later;discontinuation rate=118/130,91%), and 3 delivered. Thus, the cumulative-live-birth-rate from two stimulations in 1-year was 11% (N = 16/143). In the DuoStim group, the cumulative-live-birth-rate was 24% (N = 35/143; Fisher’s-exact-test< 0.01,power=80%). The odds-ratio of delivering in the DuoStim versus the control group adjusted for all matching criteria was 3.3,95%CI:1.6–7.0,p<0.01. This difference (0%,22%,15% and 20% in the control versus 10%,31%,46% and 40% in the DuoStim group among patients obtaining 0,1,2 and 3 blastocysts at the first stimulation, respectively) is mainly due to treatment discontinuation in the control group (98%,65%,77% and 80% among patients obtaining 0,1,2 and 3 blastocysts at the first stimulation, respectively) and the further increased maternal age at the time of second retrieval (∼6 months). Notably, 2 patients delivered 2 live-births after DuoStim (none in the control) and 14 patients with a live-birth have euploid blastocysts left (2 in the control).
Limitations, reasons for caution
Randomized-controlled-trials and cost-effectiveness analyses are desirable to confirm these data. Moreover, 75% of the patients included were >39yr and 44% obtained no blastocyst after the first stimulation. Therefore future studies among younger women and/or more women obtaining ≥1 blastocyst are advisable to set reasonable cut-off values to apply this strategy.
Wider implications of the findings: A second stimulation in the same ovarian cycle might be envisioned as a rescue strategy for poor IVF outcomes after a first stimulation, so to prevent treatment discontinuation and increase the cumulative-live-birth-rate. This is feasible since 6–7 days span the first and the second stimulation in the DuoStim protocol.

Endometriosis and Phytoestrogens: Friends or Foes? A Systematic Review. Nutrients 2021; 13:nu13082532. [PMID: 34444692 PMCID: PMC8398277 DOI: 10.3390/nu13082532] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 07/21/2021] [Accepted: 07/23/2021] [Indexed: 12/17/2022] Open
Abstract
The aim of this systematic review was to provide comprehensive and available data on the possible role of phytoestrogens (PE) for the treatment of endometriosis. We conducted an advanced, systematic search of online medical databases PubMed and Medline. Only full-length manuscripts written in English up to September 2020 were considered. A total of 60 studies were included in the systematic review. According to in vitro findings, 19 out of 22 studies reported the ability of PE in inducing anti-proliferative, anti-inflammatory and proapoptotic effects on cultured cells. Various mechanisms have been proposed to explain this in vitro action including the alteration of cell cycle proteins, the activation/inactivation of regulatory pathways, and modification of radical oxidative species levels. Thirty-eight articles on the effects of phytoestrogens on the development of endometriotic lesions in in vivo experimental animal models of endometriosis have been included. In line with in vitro findings, results also derived from animal models of endometriosis generally supported a beneficial effect of the compounds in reducing lesion growth and development. Finally, only seven studies investigated the effects of phytoestrogens intake on endometriosis in humans. The huge amount of in vitro and in vivo animal findings did not correspond to a consistent literature in the women affected. Therefore, whether the experimental findings can be translated in women is currently unknown.

Abstract
BACKGROUND Data about endometrioma ablation using energies with little thermal spread reported good results in terms of ovarian reserve and postoperative pregnancy rates. The aim of the present study was to assess the impact of one step CO<inf>2</inf> fiber laser vaporization for endometrioma on subsequent controlled ovarian stimulation. METHODS This prospective observational cohort study included a consecutive series of infertile patients who have undergone CO<inf>2</inf> fibre laser vaporization for endometrioma treatment. The primary endpoint was to assess the number of follicles per ovary growing during controlled ovarian stimulation. The secondary endpoints included the number of oocytes retrieved, the total number of embryos obtained and the cumulative clinical pregnancy rate per patient treated. RESULTS Twenty-six patients underwent assisted reproductive technology after surgery for endometriosis-related infertility. In unilateral operated ovaries at the end of controlled ovarian stimulation no significant differences emerged from comparison of total recruited follicles in the operated ovary and in the contralateral ovary (P=0.55). If considering only bilateral endometriomas, the number of recruited follicles at the end of controlled ovarian stimulation was similar in both operated ovaries (P=0.79). The number of cumulative clinical pregnancies was 15 (57.7%; 95% CI: 38.5-76.9%). When comparing women aged ≤35 years to those aged >35 years, controlled ovarian stimulation outcomes were significantly higher in the younger patients. Age at the time of assisted reproductive technology was the only independent predictor for follicular growth during ovarian hyperstimulation (95% CI: -1.27 to -0.116, P=0.027). CONCLUSIONS CO2 laser-treated endometrioma is associated with favorable reproductive assisted reproductive technology outcomes.

Early-life factors, in-utero exposures and endometriosis risk: a meta-analysis. Reprod Biomed Online 2020; 41:279-289. [PMID: 32532666 DOI: 10.1016/j.rbmo.2020.04.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 03/25/2020] [Accepted: 04/07/2020] [Indexed: 02/07/2023]
Abstract
This meta-analysis aimed to offer a general picture of the available data on the effects of early-life factors on the risk of developing endometriosis in adult life. An advanced, systematic search of the online medical databases PubMed, EMBASE and CINAHL was limited to full-length manuscripts published in English in peer-reviewed journals up to February 2019. Log of relative risk (RR) was employed to calculate the pooled effect sizes using both fixed and random effects modelling and I-squared tests to assess heterogeneity. Funnel plots were used to investigation publication bias. The meta-analysis was registered in PROSPERO (ID CRD42019138668). Six studies that included a total of 2360 women affected by endometriosis were analysed. The pooled results showed that the risk of developing endometriosis in adult life was significantly increased by being born prematurely (logRR 0.21, 95% CI -0.03 to 0.40), having a low birthweight (logRR 0.35, 95% CI -0.15 to 0.54), being formula-fed (logRR 0.65, 95% CI -0.35 to 0.95) and having been exposed to diethylstilbestrol (DES) in utero (logRR 0.65, 95% CI 0.26 to 1.04. Among intrauterine and early neonatal exposures, prematurity, birthweight, formula feeding and DES were risk factors for the development of endometriosis in adult life.

Cellular Components Contributing to Fibrosis in Endometriosis: A Literature Review. J Minim Invasive Gynecol 2019; 27:287-295.

Abstract
Endometriosis-related fibrosis represents a complex phenomenon with underlying mechanisms yet to be clarified. Fibrosis is consistently present in all disease forms and contributes to classic endometriosis-related symptoms of pain and infertility. The purpose of this literature review was to examine the role of various cellular populations and biologic mechanisms and signaling pathways in inducing fibrogenesis of endometriotic lesions. A search was performed through PubMed and MEDLINE for animal and human studies published in English in the last 23 years that examined fibrosis in superficial, ovarian, and deep infiltrating endometriosis. The main cell types found to be involved in the development of fibrosis were platelets, macrophages, ectopic endometrial cells, and sensory nerve fibers. Interactions among each of the cell types contribute to the production of fibrosis through the production of soluble factors, mostly transforming growth factor-β but also other cytokines and neuropeptides. Cell types known to be critical to the pathophysiology of endometriosis also contribute to fibrogenesis, thus supporting the theory that fibrosis is an inherent part of endometriosis.

Recurrence Rate after "One-Step" CO 2 Fiber Laser Vaporization versus Cystectomy for Ovarian Endometrioma: A 3-Year Follow-up Study. J Minim Invasive Gynecol 2019; 27:901-908. [PMID: 31377455 DOI: 10.1016/j.jmig.2019.07.027] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2019] [Revised: 07/17/2019] [Accepted: 07/30/2019] [Indexed: 11/28/2022]
Abstract
STUDY OBJECTIVE To assess postoperative recurrence rates in patients with endometriomas managed by either "one-step" CO2 fiber laser vaporization or cystectomy. DESIGN Retrospective study with prospective recording of data. SETTING University hospital. PATIENTS One hundred twenty-five patients with symptomatic endometriomas. INTERVENTIONS Patients underwent a standardized laparoscopic stripping technique (group 1) or cyst vaporization with CO2 fiber laser (group 2). After surgery, patients were incorporated in a prolonged surveillance program with periodic clinical follow-up to check for recurrence of the cyst and/or recurrence of symptoms. Endometrioma recurrence was defined as an ovarian cyst (>10 mm) with a typical aspect arising on the operated ovary identified by transvaginal ultrasound. MEASUREMENTS AND MAIN RESULTS The primary endpoint was the comparison of recurrence rates between the 2 groups. The secondary endpoint was the evaluation of endometriosis-related pain recurrence in the 2 groups. Other endpoints selected for analysis included the identification of risk factors for the recurrence of endometrioma and of endometriosis-related symptoms. The mean follow-up was 29 ± 13 months (range, 13-49). Recurrence of ovarian endometriosis was recorded in 6.3% of patients (n = 4) treated with cystectomy and in 4.9% of patients (n = 3) managed with CO2 fiber laser (p = .74). Recurrence of endometriosis-related pain was observed in 5 patients (7.8%) in group 1 and in 6 patients (9.8%) in group 2 (p = .67). Mean endometrioma diameter > 5 cm at the time of surgery was identified as the only independent poor prognostic indicator for cyst recurrence (p = .008; odds ratio [OR], 2.21; 95% confidence interval [CI], 1.19-3.32). Moreover, the presence of deep endometriosis at surgery (p = .032; OR, 4.60; 95% CI, 1.14-18.57) and discontinuation of hormonal treatment (p = .015; OR, 3.18; 95% CI, 1.25-8.06) were independent poor prognostic indicators for pain recurrence. CONCLUSION This study suggests that one-step CO2 fiber laser vaporization may be effective for endometrioma treatment because it is associated with recurrence rates comparable with those occurring after cystectomy, with the advantage of being an ovarian tissue-sparing technique.

Abstract
Endometriosis is an inflammatory disease affecting 7-10% of women throughout their reproductive life. Few data are available regarding the age at menopause of women affected by this disease. Most of the available evidence, although scanty, would indicate that both ovarian surgery for endometriomas and endometriosis per se appear to influence age at menopause. Other factors might interfere with the age at menopause of women affected by endometriosis. The purpose of this review was to examine the age at menopause in women with a history of endometriosis and to identify factors that might affect the timing of menopause.

Obstetrical complications of endometriosis, particularly deep endometriosis. Fertil Steril 2017; 108:895-912.

Abstract
Over the past few years, a new topic in the field of endometriosis has emerged: the potential impact of the disease on pregnancy outcomes. This review aims to summarize in detail the available evidence on the relationship between endometriosis, particularly deep endometriosis (DE), and obstetrical outcomes. Acute complications of DE, such as spontaneous hemoperitoneum, bowel perforation, and uterine rupture, may occur during pregnancy. Although these events represent life-threatening conditions, they are rare and unpredictable. Therefore, the current literature does not support any kind of prophylactic surgery before pregnancy to prevent such complications. Results on the impact of DE on obstetrical outcomes are debatable and characterized by several limitations, including small sample size, lack of adjustment for confounders, lack of adequate control subjects, and other methodologic flaws. For these reasons, it is not possible to draw conclusions on this topic. The strongest evidence shows that DE is associated with higher rates of placenta previa; for other obstetrical outcomes, such as miscarriage, intrauterine growth restriction, preterm birth and hypertensive disorders, results are controversial. Although it is unlikely that surgery of DE may modify the impact of the disease on the course of pregnancy, no study has yet investigated this issue.

Abstract
Uterine fibroids are the most common gynecologic benign tumors. Studies supporting a strong pregnancy-related growth of leiomyomas generally claimed a crucial role of sex steroid hormones. However, sex steroids are unlikely the unique actors involved as estrogen and progesterone achieve a pick serum concentration in the last trimester while leiomyomas show a typical increase during the first trimester. Given the rapid exponential raise in serum human Chorionic Gonadotrophin (hCG) at the beginning of gestation, we conducted a review to assess the potential role of hCG in the striking growth of leiomyomas during initial pregnancy. Fibroid growth during initial pregnancy seems to correlate to the similar increase of serum hCG levels until 12 weeks of gestation. The presence of functional Luteinizing Hormone/human Chorionic Gonadotropin (LH/hCG) receptors was demonstrated on leiomyomas. In vitro treatment of leiomyoma cells with hCG determines an up to 500% increase in cell number after three days. Expression of cyclin E and cyclin-dependent kinase 1 was significantly increased in leiomyoma cells by hCG treatment. Moreover, upon binding to the receptor, hCG stimulates prolactin secretion in leiomyoma cells, promoting cell proliferation via the mitogen-activated protein kinase cascade. Fibroid enlargement during initial pregnancy may be regulated by serum hCG.

Abstract
OBJECTIVE To compare obstetrical and neonatal outcomes of twin pregnancies conceived via assisted reproductive technology (ART) with those of naturally conceived ones and to investigate the influence of the ART procedure type on these parameters. PATIENTS AND METHODS This observational study included 450 ART and 647 spontaneous twin pregnancies delivered over 15 years at a single university-based hospital of Rome, Italy. Logistic and linear regression models adjusted for confounding factors were used to evaluate the effect of ART and the type of assisted conception (IVF/ICSI, ovulation induction ± intrauterine insemination, egg/embryo donation) on maternal and perinatal outcomes. RESULTS The mean gestational age was significantly lower in pregnancies conceived via ART. The occurrence rates of gestational diabetes, antenatal admission, prophylactic administration of corticosteroid, very preterm delivery and neonatal intensive care unit admission were higher in the ART group. Twin pregnancies achieved via egg/embryo donation had a lower risk of maternal thrombocytopenia and cervical incompetence and were at greater risk of receiving corticosteroid prophylaxis and patent ductus arteriosus than pregnancies obtained by IVF/ICSI. Conception by ovulation induction was associated with reduced risk of hyperemesis gravidarum and longer neonatal hospitalization compared to pregnancies obtained by IVF/ICSI. CONCLUSIONS Assisted conception was associated with adverse obstetrical outcomes and lower gestational age, but after adjustment for gestational age neonatal immediate outcomes were similar to those observed in the spontaneous group. There were no many important differences in the outcomes of twin pregnancies obtained by a different type of conception.

Abstract
OBJECTIVE The incidence of abnormal cervical cytology in pregnancy is similar to that reported for non-pregnant women. Furthermore, 1% of pregnant women annually screened for cervical cancer will be diagnosed with cervical intraepithelial neoplasia (CIN) of various degrees. For this reason, Pap smear should be performed in the first trimester of pregnancy. The persistence of HR-HPV infection is related to the development of CIN. However, the relationship between CIN and HR-HPV infection during pregnancy and postpartum can hardly be found. The aim of this work was to assess the proper management of abnormal cytology during and after pregnancy evaluating regression rate, persistence rate and risk of progression and the predictive role of HPV molecular tests. PATIENTS AND METHODS Patients with abnormal cervical cytology were followed-up using colposcopy and colposcopy-directed biopsies every 12 weeks. Molecular tests were performed at the moment of the cytological diagnosis. Patients not treated in pregnancy were re-evaluated with cytology, colposcopy, biopsies, HPV-DNA test and HPV-mRNA test for a final diagnosis 8 weeks postpartum. Women with a persistent CIN 2-3 lesion at this follow-up check, underwent an excisional procedure by LEEP and then re-evaluated every 6 months for a year. RESULTS HPV-DNA test showed a sensitivity of 90.5% and a negative predictive value of 96.4%. Specificity and positive predictive values were 67.9% and 43.2%, respectively. For HPV-mRNA test, a sensitivity of 76.2% and a NPV of 93.9% were found; specificity and PPV were 98.7% and 94.1% respectively. CONCLUSIONS An observational management based on the use of molecular test and particularly HPV-mRNA test for its higher specificity, is a reasonable possibility in the follow-up of CIN2/3 lesions during pregnancy.

Abstract
OBJECTIVE Poor responders represent a frustrating condition for couples undergoing IVF and clinicians, and their treatment remains disputed. To assess the efficacy and the most suitable protocol, we conducted a randomized controlled trial comparing three different protocols of ovarian stimulation in poor responder women: clomiphene citrate (CC) plus a high dose of gonadotropins and GnRH antagonist, flexible GnRH antagonist protocol and a short GnRH agonist protocol. PATIENTS AND METHODS Between July 2014 and December 2015 we enrolled 250 poor responders in a previous IVF cycle at least 3 months before. We divided into three groups: group A, 68 women treated with clomiphene citrate and FSH plus antagonist; Group B, 71 patients treated with FSH plus antagonist; Group C, 75 patients treated with FSH plus GnRH agonist. RESULTS The GnRH agonist protocol showed a significantly higher pregnancy rate (29.3% vs. 5.9% vs. 14.1% respectively) than the clomiphene and the GnRH antagonist protocol, number of mature oocytes collected, estradiol levels and endometrial thickness. The cost of medications for each baby born was lower for the GnRH agonist protocol than for the others; the implantation rate was significantly lower in the clomiphene group (4.8%) than in the GnRH antagonist group (9.3%) and the GnRH agonist groups (19.2%). No significant differences emerged for total FSH administered, days of stimulation, numbers of oocytes retrieved and embryos transferred. CONCLUSIONS This study demonstrates that short GnRH agonist protocol should be the first choice in poor responders; instead, clomiphene citrate should be avoided due to its very low success rate and high costs.

Abstract
OBJECTIVE The increased use of the intrauterine contraception (IUC) in female population and its probable relationship with cervical squamous intraepithelial lesions and cervical cancer make necessary clarify the possible interaction between the device and the pre-neoplastic lesions. PATIENTS AND METHODS Seven hundred and eighty-nine patients users of IUC and 1491 patients ever users of IUC were followed every 6 months for 3 years. Each clinical control included Papanicolau test, colposcopy, HPV-DNA test and HPV-mRNA test. Also, in patients IUC users we analyzed the type of device, years of use and average age. RESULTS Cytological sampling, histological examination, HPV-DNA test and HPV-mRNA test showed that there are not significantly differences between patients with or without IUC. CONCLUSIONS None difference arose regarding persistence and progression between patients IUC users and IUC no users, for this reason, intrauterine contraception does not seem to be a co-causal factor in the possible development of cervical cancer.

Abstract
BACKGROUND The purpose of this study is to compare laparoscopy (LPS) and laparotomy (LPT), in terms of surgical outcomes, in elderly patients (>65 years) with adnexal masses. METHODS We retrospectively reviewed a series of women older than 65 who had a diagnosis of adnexal masses. Then, all patients were divided into two different groups according to the type of surgery: 27 who underwent LPS (LPS group) and 24 who underwent LPT (LPT group). We took into consideration: age, comorbidity, histological diagnosis, surgery approach, and surgical outcome. Then, we calculated the percentages of all of these data and then χ (2) test and t-Student test were used to calculate the p value, to compare the two surgical techniques. A p value lower than 0.05 was considered to be statistically significant. RESULTS At first, we evaluated the relation between the diagnosis and the surgery approach, and we obtained statistically significant results for serous cyst, adenocarcinoma serous/mucinous, and others, and the table highlights that some of the benign masses were mostly treated with LPS, while borderline and malignant masses were treated with LPT. Then, we evaluated the comorbidities of the patients, and we found that those cases had a significantly higher prevalence of cardiovascular disease and metabolic diseases. Finally, we compared the surgery outcome of LPS versus LPT surgeries for adnexal masses in elderly women, and there were statistically significant results for postoperative complications, number of patients who needed drainage, and number of days of hospitalization after surgery. CONCLUSIONS Our results demonstrated that the patients who underwent LPS, compared to the patients who underwent LPT, have better outcomes in terms of postoperative complications (7.4 % with LPS and 37 % with LPT), number of patients who needed drainage (11.1 % with LPS and 62.5 % with LPT), and number of days of hospitalization after surgery, in term of mean (5 for LPS and 10.9 in term of LPT).

Abstract
OBJECTIVE Ovarian transposition is a highly effective surgical procedure used to preserve ovarian function in premenopausal patients with cancers requiring postoperative or primary pelvic radiotherapy. Pelvic irradiation determines severe damage of ovarian DNA and iatrogenic ovarian failure with premature menopause, necessity of long-term hormone replacement therapy and infertility. MATERIALS AND METHODS We conducted an extensive research of the literature in Medline between January 2000 and April 2015 using the key-words "ovarian transposition radiotherapy", "radiotherapy gonadal function", radiotherapy fertility sparing". The population included young women with normal ovarian function affected by cancers that required pelvic radiotherapy. We have examined 32 articles reporting on 1189 women undergoing ovarian transposition. Median age was 32.5 years, follow up was median 48 months. The procedure has been performed in patients less than 40 years of age. Surgery has been achieved by laparotomy or laparoscoy. We have analyzed effects of radiotherapy on ovarian function. RESULTS The proportion of women treated by ovarian transposition preserved ovarian function was 70%. About 86% of patients did not develop ovarian cysts and in 98-99% of cases did not occur any metastatic disease. CONCLUSIONS Ovarian transposition is associated with significant preservation of ovarian function and a low frequency of complications as cysts and metastasis. In 31% of cases the procedure can fail. Further studies are needed to evaluate the efficacy of ovarian transposition and the follow up. Ovarian transposition should be discussed at the time of cancer diagnosis in every premenopausal woman requiring pelvic radiotherapy.

Abstract
OBJECTIVE To compare diagnostic accuracy of sonohysterography vs hysteroscopy in patients with benign uterine endocavitary findings. PATIENTS AND METHODS This retrospective study evaluated 202 patients submitted to sonohysterography after transvaginal ultrasound examination suspicious for uterine endocavitary findings. Cytological sample was taken and analyzed from the fluid used to distend the uterine cavity. Of 202 patients enrolled for this study, 86 patients underwent gynaecological surgery, of whom 77 were treated with operative hysteroscopy and 9 with other gynaecological surgical techniques. Statistical analysis was performed to evaluate diagnostic agreement between sonohysterography vs hysteroscopy and cytology vs histology. RESULTS Diagnostic concordance between sonohysterography and hysteroscopy was significant (k value 0.87). The correlation between cytological and histological findings had a moderate level of concordance (k value 0.49). CONCLUSIONS Sonohysterography provides a diagnostic accuracy as well as hysteroscopy, therefore, it could be considered an alternative procedure in the diagnosis of benign uterine endocavitary findings.

Abstract
OBJECTIVE Vulvar intraepithelial neoplasia (VIN) is a premalignant lesion of the vulva. The incidence of VIN is increasing. The surgery is currently the gold standard therapy for VIN, but Imiquimod could be a completion to surgery. The aim of this study is to compare the overall complete response, the recurrence rate and the risk factors for recurrence among two groups of patients: women with high grade VIN underwent surgery and patients treated with surgery plus Imiquimod. PATIENTS AND METHODS 80 patients with histologically diagnosed VIN 2/3 were enrolled in this prospective study. Our patients were divided into two groups: 40 women underwent surgery (A) and 40 patients were treated with surgery plus Imiquimod (B). All women had a 5-year follow-up. Recurrence rate and complete response were evaluated. The following patients' characteristics were analyzed: smoke, multifocal disease, multicentric disease, degree of the lesion. RESULTS In the group A recurrence rate was 44.8%, in the group B it was 48.4%. In both groups the presence of multifocal lesions (p = 0.02) and VIN 3 (p = 0.006) before treatment was associated with a higher risk of recurrence. CONCLUSIONS This study found that surgery remains the principal approach for VIN with regard to relapse and complete response since the treatment with Imiquimod associated with surgery didn't show a lower recurrence rate. Although the surgical treatments remain the best therapeutic option for VIN with regard to recurrence and overall complete response, the combined therapy seems to be an interesting modality, but further studies are needed.

Abstract
In order to evaluate the impact of atmospheric pollutants emitted by the industrial settlement of Milazzo (Italy) on agriculture, sulphur dioxide and ozone levels in air were monitored and the data were used to estimate yield losses of the most widespread cultures. Trace element concentrations in crops and soils were also detected and metabolic profiles of soil microbial communities were considered. Vibrio fischeri test was used to appraise airborne pollutant ecotoxicity and epidemiological studies on causes of death distribution were carried out to characterize health state of people living in the area. All the sampling points were selected in farms on the basis of a theoretical meteo-diffusive model of industrial air pollutants. Experimental SO2 and O3 values mainly exceeded the threshold established by Italian and EU regulations to protect vegetation and they correspond to estimated significant crop losses. Conversely toxic element residues in soils and in agroalimentary products were generally lower than the fixed values. SO2 and O3 concentrations, toxic element contents and ecotoxicity levels of airborne pollutants were not related only to industrial site emissions, while the fluctuations on metabolic profiles of soil microbial communities seem to agree with the predicted deposition of xenobiotic compounds from the industrial plants. The epidemiological study evidenced a better health state of populations living in the investigated area than in the Messina province and the Sicily region but, inside the area, males living in the municipalities closest to the industrial settlement exhibited a worst health state than those in the very far ones.

Abstract
A rare case of primary ovarian pregnancy is reported. The multiple diagnostic problems and the unclear symptomatology delayed the time of the definitive diagnosis more than seventy five days. All the histological criteria for the classification of an ovarian pregnancy are faced in this case. The finding of a well conserved gestational sac and embryo inside the ovarian tissue makes this case even more rare and interesting. When there is a suspicion of ectopic or ovarian pregnancy the Authors strongly suggest an early laparoscopy to make a reliable and precocious diagnosis, avoid the risk of the hemoperitoneum, perform a conservative therapy and preserve the ovarian function with the patient's reproductive potential.

Reproducibility of the indirect immunobead assay for detecting sperm antibodies in serum. THE JOURNAL OF REPRODUCTIVE MEDICINE 1989; 34:259-63.

Abstract
Although an immunobead assay (IBA) for the detection of antisperm antibodies was developed several years ago and has been used for the study of immunologic infertility, no data regarding its variability and reproducibility are yet available. We evaluated the intraassay reproducibility of the indirect IBA by testing aliquots of antisperm-antibody-positive sera from two patients against the same donor sperm sample. The interassay reproducibility was evaluated by testing a positive serum sample first with different sperm samples from the same donor and second with sperm samples from different donors. The results of those experiments showed that the indirect IBA has very low intraassay variation and greater interassay variability.

An immunobead assay for antibodies to spermatozoa in serum. Comparison with traditional agglutination and immobilization tests. THE JOURNAL OF REPRODUCTIVE MEDICINE 1987; 32:188-90.

Abstract
Circulating sperm antibodies have been traditionally quantified by measuring sperm agglutination (SAT) and immobilization (SIT) in serum. Recently an indirect immunobead assay (IBA) for detecting these antibodies in serum has been reported. Immunobeads coated with rabbit antibody to one of the three major immunoglobulins (IgG, IgM and IgA) are used. The procedure involves mixing a Hepes washed sample of normal donor sperm with the individual sera followed by centrifugation and incubation with each type of immunobead preparation and observed for evidence of binding. Sera from 40 patients previously tested with SAT and SIT were compared in four groups. There was a good correlation between IgG-IBA and SIT and a poor correlation between IgG-IBA and SAT. The class of immunoglobulin detected most frequently was IgG.

Abstract
59 patients affected by amenorrhea or anovulation, 37 of whom also with galactorrhea, and with hyperprolactinemia of unknown origin (idiopathic hyperprolactinemia, 24 patients) or due to a pituitary microadenoma (tumoral hyperprolactinemia, 35 patients) were treated with metergoline (4-12 mg/day) or with bromocriptine (2.5 to 10 mg/day) for 90 days. The effectiveness of the two treatments was assessed on clinical grounds and by evaluating at monthly intervals serum progesterone levels, during the presumed luteal phase, and serum prolactin levels. The success rate with the two drugs was superimposable in terms of disappearance of galactorrhea and return of menses, normalization of prolactin levels and induction of ovulation. Also the number of pregnancies obtained (7 with metergoline, 9 with bromocriptine) was similar. With both drugs, the majority of patients responded to the treatment within the first month.

Abstract
Forty patients with hyperprolactinaemia were treated with metergoline (8 to 12 mg/day) for periods up to 5 years. Analysis of the results of clinical and biological tolerability showed that treatment was generally well tolerated and although 28 patients complained of drug-related side-effects of various kinds, principally nausea, these were usually mild, present at the beginning of treatment and disappeared spontaneously in spite of continued metergoline administration over a prolonged period. No patient stopped treatment because of side-effects. Laboratory parameters also stayed within normal levels and there was no evidence of any alterations in the ECG. It is concluded, therefore, that metergoline is a well-tolerated as well as an effective ergolinic compound for use in those patients in whom prolonged treatment with a prolactin-lowering drug is considered necessary.
