Use of Indocyanine Green to Evaluate Ovarian Perfusion After Laparoscopic Detorsion. A Step-By-Step Demonstration Video.

OBJECTIVE: Demonstrate the usefulness of using indocyanine green after laparoscopic ovarian detorsion to save the ovary. DESIGN: A step-by-step video demonstration of a surgical technique. SETTING: Ovarian torsion is one of the most common gynecological emergencies, mainly affecting patients younger than 20 years of age [1], and causes 2% to 7% of acute abdomens [2]. It is not advisable to routinely perform ovariectomy even with a necrotic ovary appearance [1]. Furthermore only in a small percentage of cases (16%) necrosis has been confirmed histologically [2]. Some studies have demonstrated that using indocyanine green to evaluate ovarian perfusion is inexpensive, low risk, and easily reproducible [3-5]. INTERVENTIONS: A 17-year-old patient was referred to our hospital for acute abdominal pain. Ultrasound revealed ovarian torsion; therefore, the patient underwent surgical treatment. During laparoscopy, the presence of a right ovarian torsion was confirmed. A lesion compatible with a hemorrhagic corpus luteum of 6 cm was present on the ovary affected. Before ovarian detorsion, indocyanine green was administered intravenously at a 0.5 mg/kg dose. The first aspect noted was the total lack of ovarian vascularization; then ovarian detorsion was performed. At this point, using technology of Rubina (KARL STORZ SE & Co. KG, Tuttlingen, Germany), it was possible to highlight the progressive ovarian revascularization. Ovarian reperfusion occurred starting from the ovarian hilum and ending at the periphery. We proceeded with enucleation of the hemorrhagic corpus luteum by stripping technique, with subsequent ovarian reconstruction with continuous 2-0 monofilament suture. Finally, we fixed the ovary to the stump of the right round ligament. The final view highlights good ovarian vascularization. No complications occurred; the patient was discharged on the first postoperative day. A 6-month follow-up ultrasound confirmed the recovery of the vascularization of ovary. CONCLUSION: Using indocyanine green represents a valid option to evaluate ovarian perfusion after detorsion. It could help the surgeon decide to save the ovary and thus allow fertility-sparing surgery in more cases.

The Deep Proteomics Approach Identified Extracellular Vesicular Proteins Correlated to Extracellular Matrix in Type One and Two Endometrial Cancer.

Among gynecological cancers, endometrial cancer is the most common in developed countries. Extracellular vesicles (EVs) are cell-derived membrane-surrounded vesicles that contain proteins involved in immune response and apoptosis. A deep proteomic approach can help to identify dysregulated extracellular matrix (ECM) proteins in EVs correlated to key pathways for tumor development. In this study, we used a proteomics approach correlating the two acquisitions-data-dependent acquisition (DDA) and data-independent acquisition (DIA)-on EVs from the conditioned medium of four cell lines identifying 428 ECM proteins. After protein quantification and statistical analysis, we found significant changes in the abundance (p < 0.05) of 67 proteins. Our bioinformatic analysis identified 26 pathways associated with the ECM. Western blotting analysis on 13 patients with type 1 and type 2 EC and 13 endometrial samples confirmed an altered abundance of MMP2. Our proteomics analysis identified the dysregulated ECM proteins involved in cancer growth. Our data can open the path to other studies for understanding the interaction among cancer cells and the rearrangement of the ECM.

Phospho-DIGE Identified Phosphoproteins Involved in Pathways Related to Tumour Growth in Endometrial Cancer.

Endometrial cancer (EC) is the most common gynecologic malignancy of the endometrium. This study focuses on EC and normal endometrium phosphoproteome to identify differentially phosphorylated proteins involved in tumorigenic signalling pathways which induce cancer growth. We obtained tissue samples from 8 types I EC at tumour stage 1 and 8 normal endometria. We analyzed the phosphoproteome by two-dimensional differential gel electrophoresis (2D-DIGE), combined with immobilized metal affinity chromatography (IMAC) and mass spectrometry for protein and phosphopeptide identification. Quantities of 34 phosphoproteins enriched by the IMAC approach were significantly different in the EC compared to the endometrium. Validation using Western blotting analysis on 13 patients with type I EC at tumour stage 1 and 13 endometria samples confirmed the altered abundance of HBB, CKB, LDHB, and HSPB1. Three EC samples were used for in-depth identification of phosphoproteins by LC-MS/MS analysis. Bioinformatic analysis revealed several tumorigenic signalling pathways. Our study highlights the involvement of the phosphoproteome in EC tumour growth. Further studies are needed to understand the role of phosphorylation in EC. Our data shed light on mechanisms that still need to be ascertained but could open the path to a new class of drugs that could hinder EC growth.

A Multi-Omics Approach Revealed Common Dysregulated Pathways in Type One and Type Two Endometrial Cancers.

Endometrial cancer (EC) is the most frequent gynecologic cancer in postmenopausal women. Pathogenetic mechanisms that are related to the onset and progression of the disease are largely still unknown. A multi-omics strategy can help identify altered pathways that could be targeted for improving therapeutical approaches. In this study we used a multi-omics approach on four EC cell lines for the identification of common dysregulated pathways in type 1 and 2 ECs. We analyzed proteomics and metabolomics of AN3CA, HEC1A, KLE and ISHIKAWA cell lines by mass spectrometry. The bioinformatic analysis identified 22 common pathways that are in common with both types of EC. In addition, we identified five proteins and 13 metabolites common to both types of EC. Western blotting analysis on 10 patients with type 1 and type 2 EC and 10 endometria samples confirmed the altered abundance of NPEPPS. Our multi-omics analysis identified dysregulated proteins and metabolites involved in EC tumor growth. Further studies are needed to understand the role of these molecules in EC. Our data can shed light on common pathways to better understand the mechanisms involved in the development and growth of EC, especially for the development of new therapies.

Hysteroscopic removal of intrauterine device in early pregnancy.

BACKGROUND: Intrauterine devices (IUDs) are commonly used as contraceptives worldwide. However, pregnancies in patients carrying this kind of device may occur. IUD removal when the woman wishes to continue their pregnancy may be very challenging. Only 9 manuscripts in literature reported such similar procedure. CASE PRESENTATION: We report the case of an hysteroscopic removal of IUD in a young woman at 6 weeks of gestation. DISCUSSION: The case reported highlights safety and efficacy of operative hysteroscopy as a method of IUD removal in early pregnancy, although other different methods have been reported in literature. In our opinion, maintaining a low infusion pressure during the procedure may help avoiding potential gestational sac damage and IUD displacement for better grasping.

Hysteroscopic Treatment of Cervical Pregnancy: A Scoping Review of the Literature.

OBJECTIVE: Many therapies have been proposed for cervical pregnancy (CP) treatment; however, there is no consensus on the best practice to adopt, mainly owing to the rarity of this condition and the lack of randomized controlled trials. Therefore, there are no clinical practice guidelines for the management of this patient set. We presented an English literature review about the hysteroscopic management of CP. DATA SOURCES: The literature review was performed according to the Preferred Reporting Items for Scoping Reviews. The search strategy aimed at identifying cases from the first patients tracked down to those diagnosed in May of 2021. We searched in PubMed, Scopus, Google Scholar, and MEDLINE databases. Mesh terms used included "Cervical Pregnancy," "Hysteroscopy," "Ectopic pregnancy," and "Resectoscopy." METHOD OF STUDY SELECTION: Case reports of randomized controlled trials, prospective controlled studies, prospective cohort studies, retrospective studies, case series, and case reports were considered eligible. Review, Letters to the Editor, and abstracts accepted at conferences were ruled out. TABULATION, INTEGRATION, AND RESULTS: We found a total of 3572 articles in all analyzed databases. A total of 2480 articles viewed were duplicated and therefore ruled out. After screening and excluding nonpertinent articles, 109 were assessed for eligibility, and 19 were included in the analysis. All articles were single case reports, small case series with no criteria selection, randomization, or study planning. We classified them as follows: cases treated with 10 mm resectoscope, with or without pretreatments of previous CP hysteroscopic approach, and cases resolved with 5 mm hysteroscopy, with or without pretreatments of previous CP hysteroscopic approach. CONCLUSION: The hysteroscopic method represents a feasible and safe approach to the CP treatment, although there are still some aspects to be clarified, such as the pretreatment need and the instruments' type and sizes based on the beta-subunit of human chorionic gonadotropin, pregnancy age, and dimension.

Gel-Based Proteomic Identification of Suprabasin as a Potential New Candidate Biomarker in Endometrial Cancer.

Endometrial cancer (EC) is the most frequent gynaecologic cancer in postmenopausal women. We used 2D-DIGE and mass spectrometry to identify candidate biomarkers in endometrial cancer, analysing the serum protein contents of 10 patients versus 10 control subjects. Using gel-based proteomics, we identified 24 candidate biomarkers, considering only spots with a fold change in volume percentage ≥ 1.5 or intensity change ≤ 0.6, which were significantly different between cases and controls (p < 0.05). We used Western blotting analysis both in the serum and tissue of 43 patients for data validation. Among the identified proteins, we selected Suprabasin (SBSN), an oncogene previously associated with poor prognosis in different cancers. SBSN principal isoforms were subjected to Western blotting analysis in serum and surgery-excised tissue: both isoforms were downregulated in the tissue. However, in serum, isoform 1 was upregulated, while isoform 2 was downregulated. Data-mining on the TCGA and GTEx projects, using the GEPIA2.0 interface, indicated a diminished SBSN expression in the Uterine Corpus Endometrial Cancer (UCEC) database compared to normal tissue, confirming proteomic results. These results suggest that SBSN, specifically isoform 2, in tissue or serum, could be a potential novel biomarker in endometrial cancer.

Laparoscopic sacrocolpopexy versus pelvic organ prolapse suspension for surgical management of pelvic organ prolapse: a retrospective study.

This retrospective surgical clinical study compares clinical and functional effects of laparoscopic sacrocolpopexy (LSC) and laparoscopic pelvic organ prolapse suspension (L-POPS) for anterior and central prolapse correction. Thirty patients enrolled were affected by a symptomatic vaginal central compartment stage 2-3 prolapse and vaginal anterior compartment stage 1-3 prolapse without vaginal posterior compartment prolapse. A successful correction of anterior and central compartments prolapse without relapses were observed in both groups (LSC group versus L-POPS group). In patients who underwent L-POPS, a de novo posterior compartment prolapse was recorded. In this group, 7/15 patients complained more bowel symptoms and underwent vaginal colpoperineoplasty. In 20% (group LSC) and in 13.3% (group L-POPS) of cases, a condition of de novo urinary stress incontinence was described. LSC seems to remain the gold standard for pelvic organ prolapse correction, while further preventive strategies should be carried out in L-POPS to avoid a de novo posterior compartment prolapse.Impact StatementWhat is already known on this subject? Laparoscopic sacrocolpopexy is the gold standard technique for the correction of pelvic organ prolapse; however, laparoscopic pelvic organ prolapse suspension, based on the surgical technique of lateral suspension, is an innovative surgical method for the treatment of POP.What do the results of this study add? L-POPS could be considered a valid alternative to LSC for women with multiple comorbidities because of less operative time and reduced surgical risks. However, in the long follow-up period, some patients underwent L-POPS complained rectal discomfort and dysfunction on quality of life questionnaire and on clinical evaluation from six to twelve months after surgery probably due to the post-operative appearance of posterior compartment prolapse.What are the implications of these findings for clinical practice and/or further research? Considering the retrospective design and the small sample size the major limits of this study, larger, prospective, randomized studies could be encouraged to better compare a modified technique of L-POPS with posterior mesh apposition (preventing the post-operative appearance of posterior compartment prolapse) with the gold standard LSC for the correction of multi-compartment POP.

Characteristics of Submucous Myomas and the Risk of Anemia.

Background and Objectives: Uterine fibroids still represent the most common indication for hysterectomy for benign pathologies. In the United States, more than 479,000 hysterectomies are performed annually, 46.6% for myomas and 47.7% in women aged from 18 to 44 years. By applying appropriateness criteria to this procedure, it has been estimated that overuse ranges from 16 to 70%. One of the main reasons that induce patients and gynecologists to consider hysterectomy is represented by severe anemia. Materials and Methods: This is a retrospective cohort study of 202 patients with uterine fibroids diagnosed by transvaginal ultrasound who underwent a hysteroscopic procedure. Myoma grade, size, location, and number were assessed by transvaginal scan and office hysteroscopy and correlated to the pre-treatment hemoglobin level. Results: Univariate analysis showed that anemia does not have a statistically significant association with myoma number and with age considered as a numerical predictor. In the patients with myoma type 0, there is a possibility of 81% having anemia regardless of menorrhagia. On the contrary, in patients with myoma type 1 or type 2, the possibility of having anemia varies according to the presence or absence of menorrhagia. If there is menorrhagia, the risk of moderate anemia is only present for myomas >60 mm. Conclusions: The results of this study may contribute to defining objective criteria for the management of submucous myomas and anemia. Our data suggest that submucosal myomas type 0 >10 mm should always be treated, putting patients at risk for anemia. Myomas type 2 and 3 should be treated for the risk of anemia in the presence of menorrhagia episodes or if > of 60 mm. Adequate management of anemia and myomas could reduce the rate of unnecessary hysterectomies.

Cotyledonoid Leiomyoma Clinical Characteristics, Imaging Features, and Review of the Literature.

Cotyledonoid leiomyoma of the uterus is a rare variant of benign uterine leiomyoma. It has a favorable attitude, despite some ultrasound presentations. A bulky uterus with a heterogeneous mass with irregular margins, high vascularity, and infiltration of the myometrium can induce the suspicion of a malignant mesenchymal tumor and lead to a radical surgical treatment. If present, some imaging features may suggest this rare type of leiomyoma, thus avoiding extensive surgery, especially in young nulliparous women. We report 13 cases of cotyledonoid leiomyoma with clinical characteristics, imaging features, and a literature review.

Scanning Probe Microscopies: Imaging and Biomechanics in Reproductive Medicine Research.

Basic and translational research in reproductive medicine can provide new insights with the application of scanning probe microscopies, such as atomic force microscopy (AFM) and scanning near-field optical microscopy (SNOM). These microscopies, which provide images with spatial resolution well beyond the optical resolution limit, enable users to achieve detailed descriptions of cell topography, inner cellular structure organization, and arrangements of single or cluster membrane proteins. A peculiar characteristic of AFM operating in force spectroscopy mode is its inherent ability to measure the interaction forces between single proteins or cells, and to quantify the mechanical properties (i.e., elasticity, viscoelasticity, and viscosity) of cells and tissues. The knowledge of the cell ultrastructure, the macromolecule organization, the protein dynamics, the investigation of biological interaction forces, and the quantification of biomechanical features can be essential clues for identifying the molecular mechanisms that govern responses in living cells. This review highlights the main findings achieved by the use of AFM and SNOM in assisted reproductive research, such as the description of gamete morphology; the quantification of mechanical properties of gametes; the role of forces in embryo development; the significance of investigating single-molecule interaction forces; the characterization of disorders of the reproductive system; and the visualization of molecular organization. New perspectives of analysis opened up by applying these techniques and the translational impacts on reproductive medicine are discussed.

CD133 Expression in Placenta Chorioangioma Presenting as a Giant Asymptomatic Mass.

Background: Placental chorioangioma is the most common benign non-trophoblastic neoplasm of the placenta. Its clinical relevance lies in the size of the tumor since larger masses cause pregnancy complications, including an unfavorable neonatal outcome. Case presentation: We report the case of a 34-year-old second gravida and nullipara at the 35th week of gestation, admitted to the gynecological department for antibiotic-resistant fever. The cardiotocography performed during hospitalization showed an abnormal fetal pattern. A 2250 g newborn was delivered by cesarean section. No complications were observed during childbirth and postpartum was insignificant. On gross inspection a white fleshy intraparenchymal mass blooming on the maternal surface was noted; routinely stained sections revealed features consistent with chorioangioma with vascular channels lined by inconspicuous endothelial cells immunoreactive for CD31 and CD133. Focal expression of CD133 was also observed in placental villi. Discussion: CD133 expression indicated the presence of stem cells in chorioangioma, suggesting their possible role in the development of mesenchymal lesions including chorioangioma.

Pelvic mass, ascites, hydrothorax: a malignant or benign condition? Meigs syndrome with high levels of CA 125.

INTRODUCTION: Abdominal-pelvic mass, ascites and pleural effusion are suggestive of malignant metastatic ovarian cancer. This triad is also present in a rare benign condition called Meigs syndrome. Rarely this condition is associated with an increased CA 125 level. CASE REPORT: A 62-year-old woman with a history of abdominal pain underwent an ultrasound (US) examination and a chest X-ray. The imaging revealed the presence of a large pelvic mass and ascites with a monolateral pleural effusion and a high level of the tumor marker CA 125. The patient underwent a total abdominal hysterectomy, salpingoophorectomy, removal of the pelvic mass, pelvic lymphadenectomy and peritoneal biopsies. The histology showed an ovarian fibrothecoma. DISCUSSION: The US analysis according to international ovarian tumor analysis simple rules revealed "inconclusive results"; the logistic regression model LR2 and Adnex suggested a high risk of malignancy. The presence of ascites and the size of the lesion associated with a high level of CA 125 affected the correct assessment of the risk of malignancy, exposing the patient to overtreatment. CONCLUSIONS: Meigs syndrome is characterized by the resolution of symptoms after surgical removal of the pelvic mass. However, it mimics the clinical picture of a malignant metastatic ovarian cancer. Clinicians have to exclude ovarian cancer and recognize the syndrome to reduce inappropriate procedures.

Laparoscopic monolateral suspension for vaginal vault prolapse: a report of an exit surgical strategy during sacralcolpopexy.

BACKGROUND: Vaginal vault prolapse is the most frequent long-term complication in patients undergoing hysterectomy and sacralcolpopexy is considered the gold standard. We report our surgical strategy maintaining single-arm mesh when the sacral promontory is not accessible to fix the mesh for an unknown sacral osteophytosis during a laparoscopic sacralcolpopexy. This is significant because, to our knowledge, the bone variant as a procedure limiting factor has never been described before. This opens new horizons for the sacralcolpopexy surgery, because it becomes necessary to know of a valid surgical alternative with mesh maintenance if this complication occurs again or to perform an assessment of the accessibility of the sacral promontory immediately after its dissection. CASE PRESENTATION: We present a case of a 75-year-old woman with recurrence of vaginal vault prolapse. A laparoscopic sacralcolpopexy was recommended. During surgery, we found that the procedure was not feasible due to the presence of an unknown osteophytosis of the sacrum which prevented the fixing of the mesh to the sacral promontory. We decided to proceed with a single-arm lateral suspension by using a modified approach of the original technique, maintaining the mesh originally shaped for the sacral colpopexy. At follow-up, the vaginal vault is well suspended. CONCLUSION: This exit strategy may represent a valid surgical alternative when laparoscopic sacral colpopexy is not possible for anatomical variants, allowing to keep the laparoscopic approach using mesh. To our knowledge, cases in which the anatomical bone variant prevented access to the sacral promontory have never been described in the literature, as bone evaluation has never been considered a limiting element of this procedure.

Ectopic Cervical Pregnancy: Treatment Route.

Background and objectives: Cervical pregnancy (CP) is a rare form of ectopic pregnancy (EP) in which the embryo implants and grows inside the endocervical canal. Early diagnosis is essential in order to allow conservative medical and surgical treatments. Although many treatment approaches are disponible, the most effective is still unclear. The aim of this study is to evaluate the efficacy of hysteroscopic management in early CP in order to preserve future fertility. Materials and Methods: This is a retrospective observational case series. Five patients with a diagnosis of CP, hemodynamically stables and managed conservatively between 2014 and 2019 at the Institute of Child and Maternal Health Burlo Garofolo in Trieste, Italy, were included. Four patients, with ßhCG levels >5000 mUi/mL were managed by hysteroscopy, with or without a previous systemic Methotrexate (MTX). One case with ßhCG levels <5000 mUi/mL was treated using MTX combined to Mifepristone and Misoprostol. Results: In one patient treated by hysteroscopy alone it occurred a profuse vaginal bleeding with necessity for blood transfusion. Haemorrhage was controlled by a second hysteroscopic procedure. No complications, such as vaginal bleeding, were recorded in the other cases. Serum ß-hCG levels become undetectable in a range of 15-40 days after hysteroscopic management; after medical treatment it become undetectable after 35 days. Serum ßhCG levels had a faster drop the day after hysteroscopy than post medical management. The onset of a spontaneous pregnancy at the normal implantation site occurred after five months in one case treated by hysteroscopy. Conclusions: Many therapeutic approaches are effective for CP treatment. Hysteroscopy, alone or in combination with MTX, may provide a greater effect on the descent of ßhCG, leading to a reduction of the hospitalization stay, decreasing costs and period for attempt pregnancy. Further prospective studies on larger samples are needed to define therapeutic protocols for CP management.

Hard and soft X-ray imaging to resolve human ovarian cortical structures.

Laboratory and synchrotron X-ray tomography are powerful tools for non-invasive studies of biological samples at micrometric resolution. In particular, the development of phase contrast imaging is enabling the visualization of sample details with a small range of attenuation coefficients, thus allowing in-depth analyses of anatomical and histological structures. Reproductive medicine is starting to profit from these techniques, mainly applied to animal models. This study reports the first imaging of human ovarian tissue where the samples consisted of surgically obtained millimetre fragments, properly fixed, stained with osmium tetroxide and included in epoxydic resin. Samples were imaged by the use of propagation phase contrast synchrotron radiation micro-computed tomography (microCT), obtained at the SYRMEP beamline of Elettra light source (Trieste, Italy), and X-ray absorption microCT at the Theoretical Biology MicroCT Imaging Laboratory in Vienna, Austria. The reconstructed microCT images were compared with the soft X-ray absorption and phase contrast images acquired at the TwinMic beamline of Elettra in order to help with the identification of structures. The resulting images allow the regions of the cortex and medulla of the ovary to be distinguished, identifying early-stage follicles and visualizing the distribution of blood vessels. The study opens to further application of micro-resolved 3D imaging to improve the understanding of human ovary's structure and support diagnostics as well as advances in reproductive technologies.

Study of the mechanical properties of fresh and cryopreserved individual human oocytes.

In assisted reproduction technologies, the cryopreservation of oocytes is a common procedure used to circumvent female infertility. However, some morphological and functional alterations of oocytes have been observed depending on the protocol applied. In this work, the mechanical response of individual human oocytes before and after a freeze-thawing procedure was characterised. Oocytes, immediately after retrieval, were morphologically evaluated by bright-field optical microscopy and their elasticity measured by indentation measurements using atomic force microscopy. Oocytes were then frozen according to the open-vitrification protocol and stored in liquid nitrogen. Afterwards, the same oocytes were thawed and the indentation measurements repeated. Using this approach, we can follow the elasticity of a set of single oocytes from retrieval up to the freeze-thawing procedure. The analysis of the resulting data shows that the retrieved healthy oocytes, which preserve their healthy morphological features after cryopreservation, maintain unchanged also in stiffness values. In contrast, oocytes having dysmorphic characteristics, before and/or after freeze-thawing, show significant variations in their mechanical response. In addition, the dysmorphic oocytes are generally observed to be softer than the healthy oocytes. Our results indicate that stiffness of healthy oocytes is not considerably affected by the open-vitrification-thawing procedure, and that distinct elasticity ranges can be identified for healthy and dysmorphic oocytes. These findings indicate that the mechanical characterization of oocytes represents an opportunity to detect cellular defects, and assess the quality and bio-viability of processes such as cryopreservation.

Total Hysteroscopic Treatment of Cervical Pregnancy: The 2-step Technique.

STUDY OBJECTIVE: To evaluate the efficacy of total surgical treatment of ectopic cervical pregnancy [1] with a minimally invasive approach performed by hysteroscopy [2]. DESIGN: Step-by-step video demonstration of the surgical technique using 5 mm hysteroscopy followed by 10 mm resectoscopy. SETTING: A research and university hospital (IRCCS Burlo Garofolo, Trieste, Italy). PATIENTS: A 41-year-old woman with an ultrasound diagnosis of ectopic cervical pregnancy at 6 + 6 weeks of gestation with a beta human chorionic gonadotropin serum level of 55.951 mUI/mL. INTERVENTIONS: We performed a 2-step technique using 5- and 10-mm hysteroscopy (Video 1). During the first step, a 5-mm Bettocchi hysteroscope (Karl Storz, Tuttlingen, Germany) with a 5F bipolar electrode Versapoint Twizzle (Gynecare, Menlo Park, CA) was used. In this phase, the gestational sac was identified in order to confirm the diagnosis and its site of implantation. Later, the gestational sac was opened, and the pregnancy was terminated by cord section under an embryoscopic view (Fig. 1). Finally, a partial vessel coagulation was performed. Afterward, the cervix was dilated, and a resectoscopy was performed. During the second step, a 10-mm Gynecare resectoscope with the bipolar Gynecare Versapoint was used and the gestational sac with the embryo was removed; subsequently, a complete chorial villi resection was achieved. At last, a coagulation of bleeding vessels on the implantation site in order to control the hemostasis was performed (Fig. 2). MEASUREMENTS AND MAIN RESULTS: The study was approved by the institutional review board. The patient was discharged 24 hours after the procedure with an uneventful postoperative course, and the beta human chorionic gonadotropin serum level became negative in 20 days. After 40 days, the ultrasound cervical findings were regular, whereas office hysteroscopy showed the implantation site scar. After 5 months, the patient was pregnant with regular intrauterine implantation (Fig. 3). CONCLUSION: The total hysteroscopic approach with a 2-step technique offers an effective, safe, and minimally invasive surgical treatment to ectopic cervical pregnancy. Considering that our method, in contrast with the recent literature [3-5], is performed without any medical treatment, we reported for the first time an approach, that deserve more clinical data to confirm its effectiveness.

Human ß-defensin 1 in follicular fluid and semen: impact on fertility.

PURPOSE: ß-defensins are antimicrobial peptides expressed at mucosal level of male and female genito-urinary tract, where they exert protective functions against infections, possibly preserving human health and fertility. In our study, we investigated the possible involvement of ß-defensins in female and male infertility in Italian infertile couples (i) evaluating the presence of human ß-defensin 1 (hBD-1) in follicular fluid (FF) and its correlation with in vitro fertilization (IVF) outcomes; (ii) investigating the relationship between hBD-1 levels in semen and IVF outcomes (comprising correlation with sperm parameters); and (iii) exploring the effect of hBD-1 peptide on spermatozoa motility in vitro. METHODS: A perspective observational analytic pilot study was conducted. hBD-1 concentration was measured with ELISA assay in FF and semen from 50 couples that underwent assisted procreation technique procedures due to infertility status. Moreover, hBD-1 exogenous peptide was administered to 29 normozoospermic semen and their motility was recorded. RESULTS: hBD-1 was detected in FF and its levels were significantly higher in women with good fertilization rate (≥ 75%), respect to those with a poor fertilization rate (< 75%). The hBD-1 semen concentrations in oligo-asthenozoospermic subjects were significantly lower than that in normozoospermic men. Instead, hBD-1 level in sperm and FF not correlated with pregnancy rate. Finally, incubation of sperm with exogenous hBD-1 significantly increased progressive motility after 1 h and 24 h. CONCLUSIONS: Being aware of the relatively small sample size and medium power, our results possibly suggest that hBD-1 could influence oocyte and sperm quality, and could improve, when exogenously added, sperm motility.

Emotional abuse moderates efficacy of an ecological momentary stress management intervention for college students.

Web-based stress management interventions are effective for college students, particularly those with interpersonal trauma histories. However, these interventions have not been assessed among those reporting childhood emotional abuse, a group with the most distress. Ecological momentary interventions (EMIs), which use mobile phones to deliver near-real-time psychosocial interventions in daily life, offer the possibility of increasing intervention efficacy. This randomized controlled trial examined the feasibility and efficacy of an EMI for reducing psychological distress among students with and without an emotional abuse history. Undergraduate students (N = 382) were randomly assigned to receive (a) an EMI that taught stress management skills, or (b) an ecological momentary assessment (EMA) with self-monitoring of stressors and mood. Both the EMI and EMA lasted for 14 days. Participants completed outcome measures (e.g., depression, anxiety, stress symptoms) at pretest, posttest, and 3-week follow-up. Overall, the EMI appeared feasible, acceptable, and usable, with 80% to 91% completion rates. Linear mixed models indicated that there were no significant Condition × Time interaction effects in the total sample, with decreases in perceived stress and increases in positive affect over time regardless of condition (EMI vs. EMA). Moderation analyses indicated that the EMI was generally more effective for those with a history of emotional abuse and that the EMA was more effective for those without such a history. Post hoc analyses demonstrated that participants wrote less in the EMI than in a web-based version of the intervention. Future interventions could target at-risk groups based on trauma history or baseline distress. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
