Menopause (New York, N.Y.) Aug 2023Ospemifene is a novel selective estrogen receptor modulator developed for the treatment of moderate to severe postmenopausal vulvovaginal atrophy (VVA). (Meta-Analysis)
Meta-Analysis
Efficacy, tolerability, and endometrial safety of ospemifene compared with current therapies for the treatment of vulvovaginal atrophy: a systematic literature review and network meta-analysis.
IMPORTANCE
Ospemifene is a novel selective estrogen receptor modulator developed for the treatment of moderate to severe postmenopausal vulvovaginal atrophy (VVA).
OBJECTIVE
The aim of the study is to perform a systematic literature review (SLR) and network meta-analysis (NMA) to assess the efficacy and safety of ospemifene compared with other therapies used in the treatment of VVA in North America and Europe.
EVIDENCE REVIEW
Electronic database searches were conducted in November 2021 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized or nonrandomized controlled trials targeting postmenopausal women with moderate to severe dyspareunia and/or vaginal dryness and involving ospemifene or at least one VVA local treatment were considered. Efficacy data included changes from baseline in superficial and parabasal cells, vaginal pH, and the most bothersome symptom of vaginal dryness or dyspareunia, as required for regulatory approval. Endometrial outcomes were endometrial thickness and histologic classifications, including endometrial polyp, hyperplasia, and cancer. For efficacy and safety outcomes, a Bayesian NMA was performed. Endometrial outcomes were compared in descriptive analyses.
FINDINGS
A total of 44 controlled trials met the eligibility criteria ( N = 12,637 participants). Network meta-analysis results showed that ospemifene was not statistically different from other active therapies in most efficacy and safety results. For all treatments, including ospemifene, the posttreatment endometrial thickness values (up to 52 wk of treatment) were under the recognized clinical threshold value of 4 mm for significant risk of endometrial pathology. Specifically, for women treated with ospemifene, endometrial thickness ranged between 2.1 and 2.3 mm at baseline and 2.5 and 3.2 mm after treatment. No cases of endometrial carcinoma or hyperplasia were observed in ospemifene trials, nor polyps with atypical hyperplasia or cancer after up to 52 weeks of treatment.
CONCLUSIONS AND RELEVANCE
Ospemifene is an efficacious, well-tolerated, and safe therapeutic option for postmenopausal women with moderate to severe symptoms of VVA. Efficacy and safety outcomes with ospemifene are similar to other VVA therapies in North America and Europe.

OBJECTIVES
In this retrospective observational study, cases from our institution were included and the published literature reviewed to investigate the diagnosis and prognosis of cervical rhabdomyosarcoma, a rare group of tumours.
MATERIAL AND METHODS
The clinicopathological data of 12 patients with cervical rhabdomyosarcoma (RMS) treated at the West China Second University Hospital of Sichuan University from January 2006 to May 2023 were collected, and their clinicopathological characteristics, diagnoses, treatments, prognoses and pregnancy outcomes were retrospectively analysed.
RESULTS
(1) Clinical characteristics: The ages of the 12 RMS patients ranged from 15 to 50 years, with a median age of 17 years. Five of the patients were adults, and seven were adolescents. The initial symptoms were vaginal bleeding in 5 patients, vaginal tissue prolapse in 6 patients, and abdominal pain and urinary frequency in 1 patient. Two patients were considered to have "cervical polyps" and underwent polypectomy at the other hospitals, but the cervical mass recurred soon thereafter. (2) Pathological features: The maximum tumour diameter ranged from 3 to 25 cm. The twelve cases of cervical RMS consisted of embryonal rhabdomyosarcoma (ERMS) in 7 adolescents, ERMS in 3 adults, and pleomorphic rhabdomyosarcoma (PRMS) in 2 adults. Immunohistochemical results showed the expression of one or more characteristic markers of RMS. We reclassified tumour stage according to the Intergroup Rhabdomyosarcoma Study (IRS) clinical group and tumour node metastasis (TNM) classification. (3) Treatment: Eight patients underwent radical surgery (66.7%, 8/12), including all 5 of the included adults and 3 of the adolescents, 2 of whom were treated 10 years ago. Conservative surgical resection was performed on four patients (33.3%, 4/12), all of whom were adolescents. Postoperative chemotherapy was given to all patients except one, but one patient who underwent radical surgery discontinued chemotherapy on her own without receiving a full course. Two of the ERMS patients underwent preoperative chemotherapy, and the lesions were significantly reduced. (4) Prognosis: One of the 12 patients with cervical RMS was lost to follow-up. Of the remaining 11 patients, 10 (including seven adolescents and three adults) survived tumour free (90.9%, 10/11), and 1 adult patient with existing pulmonary multiple metastases (IRS stage IV, T2N0M1) at the initial diagnosis survived 9 months with progression-free disease (9.1%, 1/11). The median survival time was 91 months (5 to 213 months). Among 4 patients receiving fertility-sparing management, 1 conceived and delivered successfully (25%).
CONCLUSIONS
The treatment of cervical RMS must take the patient's age and reproductive intent into account. The overall prognosis for cervical RMS in children and adolescents is good, and conservative surgical resection combined with chemotherapy is recommended to preserve fertility. The pregnancy outcome is also worth anticipating. For patients who have completed childbirth, radical surgery is preferred. Approaches to accurately assessing the patient's condition, grasping the indications and scope of surgery, and developing chemoradiotherapy regimens deserve further exploration.

STUDY OBJECTIVE
To investigate the feasibility of operative hysteroscopy by a hysteroscopic tissue removal system (HTRS) without anesthesia in women with endometrial polyps (EP) or retained products of conception (RPOC).
DESIGN
Prospective observational cohort study.
SETTING
University-affiliated Department of Obstetrics and Gynecology.
PATIENTS
Consenting women aged >18 years diagnosed with EP or RPOC from 9/2022 to 8/2023 confirmed by a prior office hysteroscopy.
INTERVENTIONS
Office-based vaginoscopic operative hysteroscopy without anesthesia using the Mini-Elite Truclear HTRS. Oral misoprostol was prescribed for cervical ripening. The patients rated intraoperative and 5-minute postoperative pain levels on a visual analog scale, with mild pain defined as a score of 0 to 4, moderate as 5 to 7, and severe as 8 to 10. A successful procedure was defined as complete removal of the pathology.
MEASUREMENTS AND MAIN RESULTS
Fifty patients were included in this pilot study, and 47 (94.0%) procedures were completed successfully, including 21/24 (87.5%) cases of EP and all cases of RPOC (26/26, p = .06). No intra- or postoperative complications occurred. The intraoperative pain levels were rated as mild, moderate, and severe by 26 (52.0%), 16 (32.0%) and 8 (16.0%) patients, respectively. Severe intraoperative pain was more common in nulliparous women and those >10 years from their last vaginal delivery and was not associated with patient age, menopausal status, presence of abnormal uterine bleeding, or pathology size. Severe postoperative pain, reported by 5 (10.0%) patients, was significantly associated with removal of EP compared with RPOC, longer operative time, and nulliparity or >10 years from the last vaginal delivery. The procedure was considered acceptable by 46 (92.0%) patients, and 45 (90.0%) would recommend it to a friend/relative.
CONCLUSIONS
Office-based operative hysteroscopy by the HTRS is successful and well tolerated by most women, especially for RPOC removal.

OBJECTIVE
To describe the clinical presentation, diagnostic imaging findings, surgical technique, histopathological diagnosis, and postoperative outcome in 3 cats with extensive vaginal masses.
ANIMALS
Medical records of cats diagnosed with vaginal masses that had a bilateral pubic and ischial osteotomy and vaginectomy between 2004 and 2022 were retrospectively reviewed. Three cats met the inclusion criteria.
CLINICAL PRESENTATION
Histopathological diagnosis included T-cell-rich B-cell lymphoma (n = 1), mycetoma (1), and vaginal polyp (1). Diagnostic imaging included CT (n = 2) and MRI (1), and tumor length/width/height percentages in relation to the pelvic dimensions were 53% X 62% X 63% (case 1), 50% X 100% X 60% (case 2), and 150% X 120% X 120% (case 3). A bilateral pubic and ischial osteotomy was performed in all 3 cases.
RESULTS
All 3 cases developed mild pelvic-limb splaying postoperatively; all resolved within 8 weeks, and 2 cases fully resolved within 14 days. Two of the 3 cases presented with mild stranguria postoperatively, which resolved fully in both cases.
CLINICAL RELEVANCE
Vaginal neoplasia, either malignant or benign, is infrequently reported in cats in the veterinary literature. Bilateral pubic and ischial osteotomy for resection of vaginal masses in cats is a successful surgical approach, offering good exposure for resection of large vaginal masses, with minimal postoperative complications.

Reproductive Biomedicine Online Feb 2024What are the different characteristics of vaginal microbial composition between patients with endometrial polypoid lesions and controls?
RESEARCH QUESTION
What are the different characteristics of vaginal microbial composition between patients with endometrial polypoid lesions and controls?
DESIGN
This cohort study compared the pre-operative microbial compositions of vaginal samples in a cohort of 703 women with endometrial polypoid lesions [293 and 410 women diagnosed and not diagnosed with polyps pathologically (polyps group and not-polyps group, respectively] and 703 women in the control group. Bacterial abundance, diversity, differential taxa and microbial network structure were assessed using 16S rRNA gene sequencing. Predictive algorithms were used to determine the functional pathways of vaginal microbiota within the cohort.
RESULTS
The control group exhibited higher relative abundance of Lactobacillus crispatus in comparison with the polypoid lesions group (P = 0.0427). Beta diversity of vaginal microbiota differed significantly between the groups (P < 0.05). Comparing the polyps group with the not-polyps group, Leptotrichia spp. and Cutibacterium spp. were more abundant in the polyps group, and Fannyhessea spp., Acinetobacter spp. and Achromobacter spp. were more abundant in the not-polyps group. The control group exhibited higher abundance of Bifidobacterium spp., Achromobacter spp. and Escherichia/Shigella spp. (false discovery rate < 0.05). Furthermore, the polyps group and not-polyps group displayed more complex co-occurrence networks compared with the control group.
CONCLUSIONS
The results of this study provide compelling evidence supporting associations between vaginal microbiota and endometrial polypoid lesions, highlighting the potential relationship between a well-balanced vaginal microbial ecosystem and a healthy intrauterine environment.

Vaginal fibroepithelial polyps are rare benign tumors of the mucosa of the anterior vaginal wall. In extremely rare cases, they may originate from the posterior vaginal wall or be complicated by torsion. Our case concerns a 63-year-old patient who presented to the gynecology outpatient clinic of the General Hospital of Trikala with minor vaginal bleeding. On vaginal examination, a large pedunculated painless hemorrhagic polypoid mass was noticed, originating from the posterior vaginal wall. A torsion of the pedunculated vaginal tumor was suspected, leading to its surgical excision with clear resection margins. Due to extensive tissue necrosis, accurate histological identification of the vaginal neoplasm was not possible. Histological examination excluded vaginal malignancy. Based predominantly on the clinical and morphological features of the vaginal lesion, a diagnosis of vaginal fibroepithelial polyp with torsion was made, acknowledging its limitations. The patient was discharged from the clinic the same afternoon following the surgery. Three months later, no recurrence of the lesion in the vaginal wall was noted. Following the case presentation, this paper provides a brief literature review of this rare entity, focusing on the diagnostic and therapeutic approaches.

Journal of Lower Genital Tract Disease Jan 2024We aimed to examine the diagnostic value of colposcopy in a large cohort of pregnant women with unexplained vaginal bleeding during the second or third trimester.
OBJECTIVES
We aimed to examine the diagnostic value of colposcopy in a large cohort of pregnant women with unexplained vaginal bleeding during the second or third trimester.
MATERIALS AND METHODS
This retrospective study included women who underwent colposcopy due to vaginal bleeding in the second and third trimesters during 2012-2022 at a tertiary care hospital. Demographics, obstetric data, bleeding characteristics, colposcopy results, cervical cytology testing, a sonogram directed at the placenta, and birth details were collected.
RESULTS
In total, 364 women were included. The mean maternal age was 29.7 years and the mean gestational age at examination was 30.7 weeks. Vaginal bleeding was mild in 80.8%, moderate in 14.6%, and severe in 4.7%. Only 3.3% had been vaccinated against human papilloma virus and 25.5% underwent a Pap smear study before pregnancy. Colposcopy diagnosed the bleeding source in 83 women (22.8%). The colposcopic examination revealed vaginal bleeding due to contact bleeding from ectropion in 46 (12.6%), a decidual/cervical polyp in 37 (10.2%), acetowhite epithelium in 12 (3.3%), herpes genetalis in 2 (0.5%), and bleeding from vaginal varices in 2 (0.5%). Of those who were recommended a follow-up examination after the postpartum period, only 49.1% completed such.Among women with compared to without postcoital bleeding ( N = 72), the risk of abnormal colposcopic findings was higher (24 [33.3%] vs 54 [19.7%], p = .017) and the rate of abnormal Pap smear was higher (7 [13.2%] vs 7 [3.2%], p = .008).
CONCLUSIONS
Colposcopy can be a valuable diagnostic tool for women with unexplained vaginal bleeding in the second or third trimester.

BACKGROUND
Insulin resistance (IR) induces hyperinsulinemia, which activates downstream signaling pathways such as the phosphatidylinositol-3-kinase/protein kinase B (PI3K/AKT) pathway, ultimately leading to abnormal proliferation and apoptosis of endometrial cells. This is thought to be a key pathogenic mechanism underlying the development of endometrial polyps (EP). This study aims to investigate the relationship between IR and the development of EP, the expression levels of downstream signaling molecules, including PI3K and AKT, and related laboratory parameters were examined.
METHODS
A total of 100 patients who visited the gynecology outpatient clinic of Zhongda Hospital affiliated with Southeast University from May 2021 to March 2023 and were diagnosed with abnormal endometrial echoes by vaginal ultrasound and underwent hysteroscopic diagnostic curettage were enrolled in this study. General data and relevant hematological indicators were compared, and intraoperative specimens were obtained for pathological examination. Possible factors influencing the development of endometrial polyps were analyzed using Pearson correlation analysis and logistic regression analysis.
RESULTS
In terms of body mass index, waist circumference, fasting insulin, insulin resistance index, serum total testosterone, and free testosterone index, women of childbearing age in the endometrial polyp group had higher values than those in the non-polyp group, while sex hormone-binding globulin in the endometrial polyp group was lower than that in the non-polyp group, and the differences were statistically significant (P < 0.05). The expression scores and mRNA expression levels of PI3K and AKT proteins were higher in the EP group than in the non-EP group (p < 0.05). Pearson correlation analysis showed a positive correlation between HOMA-IR and the expression scores of PI3K and AKT proteins (p < 0.01).
CONCLUSIONS
Insulin resistance and abnormal activation of the phosphatidylinositol 3-kinase/protein kinase B signaling pathway may be potential pathogenic mechanisms for the development of endometrial polyps.
