Background: We conducted this study to clarify the magnetic resonance imaging (MRI) characteristics of lobular endocervical glandular hyperplasia (LEGH) and Nabothian cysts., Methods: This study included 48 patients who underwent hysterectomy at our institution between 2016 and 2020 for suspected LEGH. Histopathological studies confirmed the presence of 25 Nabothian cysts and 23 cases of LEGH. We retrospectively analyzed five characteristic MRI findings: (1) located at the upper cervical canal, (2) positioned within the cervical stroma, (3) not circumscribing the cervical canal, (4) low- to iso-intensity on T1-weighted images (T1WI), and (5) "cosmos" or "microcystic" pattern. We compared the diagnostic accuracy of these findings for LEGH and Nabothian cysts using sensitivity, specificity, and predictive values. Combinations of findings were also calculated., Results: The characteristics "cosmos" or "microcystic" pattern, lesion not circumscribing the cervical canal, and low/iso-intensity on T1WI had a sensitivity and specificity greater than 50%. The sensitivity was 73.9% and specificity 84.0% when a combination of "cosmos" or "microcystic" pattern and lesion not circumscribing the cervical canal was present., Conclusion: The coexistence of a "cosmos" or "microcystic" pattern and not circumscribing the cervical canal was the most characteristic finding that distinguished LEGH from Nabothian cysts. When neither of these findings is present, Nabothian cyst can be suspected., (© 2024. The Author(s).)

Study Objective: This study aimed to develop and describe a novel surgical procedure that involves hysteroscopic fenestration with precise incision of the complete uterine septum and double cervix preservation after magnetic resonance imaging (MRI) evaluation in patients and to evaluate its efficacy., Design: A prospective consecutive clinical study., Setting: A university teaching hospital., Patients: Twenty-four patients with complete septate uterus and double cervix., Interventions: Three-dimensional reconstruction of uterus was performed with pelvic MRI and three-dimensional SPACE sequence scanning. Hysteroscopic fenestration with precise incision of the cavity septum and double cervix preservation was performed in patients. Three months after operation, follow-up pelvic MRI and second-look hysteroscopy were performed conventionally., Measurements and Main Results: Operating time, blood loss, operative complications, MRI and hysteroscopic changes of uterus, symptoms improvement, and reproductive outcomes were assessed. The surgery was successfully completed without any intraoperative complications in all patients. Operating time was 21.71 ± 8.28 minutes (range, 10-40 minutes) and blood loss was 9.92 ± 7.14 mL (range, 5-30 mL). Postoperative MRI showed the uterine anteroposterior diameter (3.66 cm vs 3.92 cm; p <.05) was increased. Postoperative MRI and the second-look hysteroscopy showed the cavity shape and uterine volume were expanded to the normal. Symptoms of dysmenorrhea, abnormal uterine bleeding, and dyspareunia were ameliorated after the surgery in 70% of patients (7 of 10), 60% of patients (3 of 5), and 1 patient, respectively. The preoperative spontaneous abortion rate was 80% (4 of 5) and the postoperative spontaneous abortion rate was 11.11% (1 of 9). After the surgery, there were 2 ongoing pregnancies and 6 pregnancies ended in term births. Two live births were delivered by cesarean section and 4 by vaginal delivery without cervical incompetence during pregnancy., Conclusions: Hysteroscopic fenestration with precise incision of the uterine septum and double cervix preservation is an effective surgical procedure., (Copyright © 2023 AAGL.

Objective:  To evaluate whether colposcopy-directed biopsy is necessary to increase the accuracy of diagnosing cervical intraepithelial lesions in relation to colposcopy., Methods:  We performed a retrospective, observational study by analyzing medical records obtained from Hospital de Clínicas do Paraná from February 2008 to February 2018. Patients with results of Pap tests, colposcopy, colposcopy-directed biopsy, and surgical procedures (high-frequency surgery or cold conization) were included. Data such as quadrants involved during colposcopy and age differences were also analyzed., Results:  A total of 299 women were included. Colposcopy was found to have an accuracy rate of 76.25% (95% confidence interval [CI], 71.4-81.1). Among the highest-grade lesions, the accuracy rate was 80.5% (95% CI, 75.7-85.3). The accuracy rates for biopsy were 79.6% (95% CI, 75-84.2) and 84.6% (95% CI, 80-89.1) for the highest-grade lesions. High-grade lesions were accurately confirmed in 76.9% and 85% of patients with 1 and 2 or more affected quadrants, respectively. For women younger than 40 years, the accuracy rates were 77.6% and 80.8% for colposcopy and biopsy, respectively. For women 40 years or older, the accuracy rates were 72.5% and 76.3% for colposcopy and biopsy, respectively., Conclusion:  There is no difference between the accuracy of colposcopy and that of biopsy in diagnosing cervical intraepithelial lesions in relation with the result of conization. The patients who received the greatest benefit when biopsy was not performed were those with high-grade lesions at colposcopy, a lesion involving 2 or more quadrants, and those younger than 40 years., Competing Interests: The authors have no conflict of interests to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

Objective: Preoperative short cervical length (CL) remains a major risk factor for preterm birth after laser surgery for twin-twin transfusion syndrome (TTTS), but the optimal intervention to prolong pregnancy remains elusive. The objective of this study was to compare secondary methods for the prevention of preterm birth in twin pregnancies with TTTS undergoing fetoscopic laser photocoagulation (FLP), in the setting of a short cervix at the time of FLP, in five North American Fetal Treatment Network (NAFTNet) centers., Methods: This was a secondary analysis of data collected prospectively at five NAFTNet centers, conducted from January 2013 to March 2020. Inclusion criteria were a monochorionic diamniotic twin pregnancy complicated by TTTS, undergoing FLP, with preoperative CL < 30 mm. Management options for a short cervix included expectant management, vaginal progesterone, pessary (Arabin, incontinence or Bioteque cup), cervical cerclage or a combination of two or more treatments. Patients were not included if the intervention was initiated solely on the basis of having a twin gestation rather than at the diagnosis of a short cervix. Demographics, ultrasound characteristics, operative data and outcomes were compared. The primary outcome was FLP-to-delivery interval. Propensity-score matching was performed, with each treatment group matched (1:1) to the expectant-management group for CL, in order to estimate the effect of each treatment on the FLP-to-delivery interval., Results: A total of 255 women with a twin pregnancy complicated by TTTS and a short cervix undergoing FLP were included in the study. Of these, 151 (59%) were managed expectantly, 32 (13%) had vaginal progesterone only, 21 (8%) had pessary only, 21 (8%) had cervical cerclage only and 30 (12%) had a combination of treatments. A greater proportion of patients in the combined-treatment group had had a prior preterm birth compared with those in the expectant-management group (33% vs 9%; P = 0.01). Mean preoperative CL was shorter in the pessary, cervical-cerclage and combined-treatment groups (14-16 mm) than in the expectant-management and vaginal-progesterone groups (22 mm for both) (P < 0.001). There was no significant difference in FLP-to-delivery interval between the groups, nor in gestational age at delivery or the rate of live birth or neonatal survival. Vaginal progesterone was associated with a decrease in the risk of delivery before 28 weeks' gestation compared with cervical cerclage and combined treatment (P = 0.03). Using propensity-score matching for CL, cervical cerclage was associated with a reduction in FLP-to-delivery interval of 13 days, as compared with expectant management., Conclusions: A large proportion of pregnancies with TTTS and a short maternal cervix undergoing FLP were managed expectantly for a short cervix, establishing a high (62%) risk of delivery before 32 weeks in this condition. No treatment that significantly improved outcome was identified; however, there were significant differences in potential confounders and there were also likely to be unmeasured confounders. Cervical cerclage should not be offered as a secondary prevention for preterm birth in twin pregnancies with TTTS and a short cervix undergoing FLP. A large randomized controlled trial is urgently needed to determine the effects of treatments for the prevention of preterm birth in these pregnancies. © 2021 International Society of Ultrasound in Obstetrics and Gynecology., (© 2021 International Society of Ultrasound in Obstetrics and Gynecology.)

Cervical cytology has remained a diagnostically challenging area despite its long and widespread use. At least part of this challenge has stemmed from the cytomorphologic overlap between benign and neoplastic processes. The present review has highlighted select benign processes that present diagnostic pitfalls. For each of these, we have discussed the pertinent cytologic features and emphasized the morphologic clues that will aid in distinguishing the benign entities from the neoplastic processes they mimic., (Copyright © 2020 American Society of Cytopathology.

Objective: Hysteroscopy is considered the gold standard technique for the diagnosis and management of intrauterine pathology allowing to "see and treat" patients in 1 session if desired [1-3]. Pain and the inability to enter the uterine cavity are the most common limitations of hysteroscopy, especially when performed in an office setting [4-7]. Cervical stenosis is a common hysteroscopic finding frequently encountered in postmenopausal women, especially in patients with a history of cervical procedures such as cone biopsy [8]. It represents a challenge even for the most expert hysteroscopist. Overcoming the stenosis of the external cervical os is technically more demanding than facing the obliteration of the internal os. The aim of this video article is to illustrate the use of simple techniques that allow the hysteroscopist to safely identify the location of the external cervical os and to overcome the difficulties in entering the uterine cavity during in-office hysteroscopy in patients with severe cervical stenosis including those with complete obliteration of the external cervical os. These techniques are easy to adopt and can be used in different clinical situations in which the hysteroscopic evaluation of the uterine cavity is needed in women with severe cervical stenosis., Design: A series of videos of challenging cases with severe cervical stenosis with complete obliteration of the external cervical os are presented that demonstrate maneuvers to properly identify and enter the cervical canal, unfolding key aspects of the procedure. Tips and tricks to facilitate the adoption of these useful maneuvers into clinical practice are highlighted., Setting: In-office diagnostic hysteroscopy was performed using a 5-mm rigid continuous flow operative hysteroscope. Patients were placed in a dorsal lithotomy position. The vaginoscopy "no touch" technique was used [9]. No anesthesia or sedation was administered to any of the patients. Normal saline was used as distention media., Interventions: Taking advantage of the magnification provided by the hysteroscope, the location of the external cervical os was determined. In cases in which the external cervical os was not clearly recognized, the cervix was gently probed with the use of the uterine palpator, grasper, or scissors (Fig. 1). Recognition of the landmarks of the cervical canal provides reassurance of the adequate identification of the external cervical os and facilitates the use of the correct plane of dissection that leads into the uterine cavity (Fig. 2). Additional maneuvers that are useful to navigate the endocervical canal to overcome stenosis of the internal cervical os are also illustrated., Conclusion: The combination of a delicate technique and operator experience aids in overcoming the challenge of cervical stenosis in an office setting. Adopting the presented tips and tricks to enter the uterine cavity in the presence of severe cervical stenosis will reduce the rate of failed hysteroscopic procedures, decreasing the need to take patients to the operating room and the use of general anesthesia., (Copyright © 2020 AAGL.

Prostatic-type differentiation in the lower female genital tract is encountered rarely and its causes and clinical associations are not well established. Within the vagina, reports to date have invariably described ectopic prostatic-type differentiation as restricted to the lamina propria. We recently encountered a patient receiving testosterone for gender dysphoria whose vaginectomy specimen showed a prostatic glandular proliferation within the surface epithelium. To elucidate its potential association with androgen exposure, we sought similar lesions, resected over a 26-year period, from patients with exogenous or endogenous androgen excess. Thirteen cases were identified, involving the vagina (n=12) and exocervix (n=1). The most common clinical context was gender dysphoria with long-term testosterone therapy; the lesion was present in 7 of 8 gender-dysphoric patients examined. Four other patients had congenital disorders of sexual development associated with endogenous androgen excess (congenital adrenal hyperplasia, 46,XY disorder of sexual development, and ovotesticular disorder of sexual development). Two had no known exposure to androgen excess. Immunohistochemically, glands stained for NKX3.1 (100% of cases), androgen receptor (100%), CK7 (92%), and prostate-specific antigen (69%). Follow-up (median duration, 11 mo) showed no masses or neoplasia. We propose the designation "androgen-associated prostatic metaplasia" for this form of prostate tissue with distinctive clinical, histologic and immunohistochemical features. It is novel and previously unrecognized within the vagina. It is strikingly prevalent among patients undergoing gender-affirming surgery, an increasingly common procedure. Recognition is important to distinguish it from other potentially neoplastic glandular lesions and facilitate accrual of more follow-up data to better understand its natural history.

Trichomonas vaginalis is the most common nonviral sexually transmitted infection. According to the 2019 WHO cancer report, cervical cancer is the fourth most frequent cancer in women. However, previous research, which has not included a large-scale study to date, has revealed that Trichomonas vaginalis increases cervical cancer risk. In this study, we investigated a group of Asian females in Taiwan to determine the association between trichomoniasis and the risk of developing cervical lesions, including cancer, neoplasm, and dysplasia. We conducted a nested case-control study by using the National Health Insurance (NHI) program database in Taiwan. The International Classification of Diseases, 9th Revision classifications (ICD-9-CM) was used to categorize all of the medical conditions for each patient in the case and control groups. The adjusted odds ratio (AOR) and 95% confidence interval (CI) for the association between trichomoniasis and cervical lesions were estimated using multivariable conditional logistic regression to adjust for all comorbidities and variables. In total, 54,003 individuals were enrolled in the case group and 216,012 were enrolled in the control group. Trichomonas vaginalis exposure had a significant association with cervical lesions (AOR 2.656, 95% CI = 1.411-5.353, p = 0.003), especially cervical cancer (AOR 3.684, 95% CI = 1.622-6.094, p = 0.001). In patients with both trichomoniasis and depression, the relative risk increased 7.480-fold compared to those without trichomoniasis or depression. In conclusion, female patients with Trichomonas vaginalis exposure had a significantly higher risk of developing cervical lesions (especially cervical cancer) than those without exposure.

Objective: Additional risk factors for preterm delivery in pregnant women with cervical shortening are not fully understood; however, mid-trimester cervical shortening is accepted as a risk factor for preterm delivery. This study aimed to identify risk factors associated with subsequent preterm delivery among patients with short cervix detected after late mid-trimester., Materials and Methods: This was a retrospective study of medical data from a single perinatal tertiary facility. We identified 134 asymptomatic women with singleton pregnancies where cervical shortening (≤25 mm) was detected during routine universal screening at 22-33 weeks. Statistical analyses were conducted to identify causal relationships between the incidence of preterm delivery and known risk factors for preterm delivery., Results: Incidence of preterm delivery was 27.6% (37/134) and preterm premature rupture of membrane was preceded in 46.0% (17/37) of the women with preterm delivery. Using logistic regression analysis, we identified uterine contractions [aOR 4.25, 95% confidence intervals (CI):1.68-12.1] and increased C-reactive protein (CRP) and increased white blood cell (WBC) in blood test (CRP: aOR 3.45, 95% CI:1.50-9.71; WBC: aOR 1.28, 95% CI: 1.08-1.55) as risk factors which significantly increased the risk of preterm delivery among women diagnosed with short cervix. Preterm delivery occurred in 91% of women positive for both uterine contractions and CRP >0.5 mg/dl., Conclusions: Uterine contraction and elevated CRP were additional risk factors for preterm delivery among women with short cervix. These results might be clinically useful to evaluate subsequent risk for preterm delivery in asymptomatic pregnant women presenting with short cervix in mid-pregnancy., (Copyright © 2020.

Female genital tract tuberculosis (FGTB) is a chronic disease with varied presentation. The diagnosis of FGTB for early institution of treatment remains a clinical challenge. Its laboratory diagnosis is difficult because of paucibacillary nature of the condition and limitation of available diagnostic tests. In view of the intricate problems in diagnosis of FGTB, physicians tend to over treat with empirical anti-tuberculosis drugs. Apart from concerns of drug toxicity, this may be a contributing factor in the increasing incidence of multidrug-resistant TB reported in India. The main goal for advances in TB diagnostics is to reduce delay in diagnosis and treatment. In addition, there should be reduced complexity, improving robustness, and improving accuracy of the laboratory test for diagnosis of Female genital tuberculosis., Objective: This narrative review is written with the following objectives. 1) To get a comprehensive overview as well as recent advances in diagnostic test used in the detection of FGTB. 2) To understand the limitations as well as advantages of these laboratory diagnostic test. 3) To provide clinical guidance regarding the detection in susceptible women., Method: The literature search was performed using electronic database of Pubmed, Medline, Embase and Google Scholar. Grey literature search was also done. Studies published in English were included. Following keywords were used for search - Tuberculosis, extra pulmonary tuberculosis, female genital tuberculosis, diagnosis of female genital tract tuberculosis. The personal knowledge and experience of authors in the field, helped in archiving the relevant articles., Result: Studies suggest that though culture is an invaluable contributor in the diagnosis of FGTB, molecular tests like PCR, LAMP, Xpert MTB/RIF and line probe assays have shown potential and are now being explored to strengthen the diagnostic algorithm of FGTB., Conclusion: The use of algorithm approach with combination of both rapid culture and newer molecular techniques will facilitate the accurate and timely diagnosis of FGTB., Competing Interests: Declaration of Competing Interest There are no conflicts of interest., (Copyright © 2020 Tuberculosis Association of India.

Background: To examine differences in the plasma levels of miRNA-21, - 214, -34a, and -200a in patients with persistent high-risk human papillomavirus (hr-HPV) infection or with cervical lesions of different grades., Methods: Venous blood was collected from 232 individuals to measure the plasma expression levels of miRNA-21, - 214, -34a, and -200a. The subjects included normal controls and patients with persistent hr-HPV infection, CIN1, CIN2, CIN3, or cervical cancer (n = 42, 31, 19, 54, 71, and 15 patients, respectively). Cervical conization specimens were collected from all the women. To ensure the accuracy of histopathology, three consecutive tissue sections with an identical diagnosis were selected, and dissection samples were taken from them for miRNA detection. Eligible cases met the inclusion criteria based on sample observation using the middle slice of sandwich tissue sections from the pathological tissue in accordance with the diagnosis of CIN1, CIN2 and CIN3 in 8, 29, and 26 cases, respectively. The miRNA-21, - 214, -34a, and -200a expression levels in the paraffin-embedded tissue samples were determined. The percentage of patients with a CIN2+ diagnosis at 30-49 years old was significantly different from that of those diagnosed with CIN1. The incidence of CIN2+ patients exposed to passive smoking was significantly different from that of CIN1- patients. The percentage of CIN2+ patients with three pregnancies was significantly different from that of those with CIN1, and the percentage of CIN2+ subjects with ≥4 pregnancies was significantly different from that of CIN1- patients. The number of CIN2+ patients with two or more induced abortions was significantly different from that of patients with CIN1. The percentage of CIN2+ patients who underwent a caesarean section was significantly different from that of patients with CIN. The percentage of CIN2+ patients with first-degree relatives with cancer was significantly different from that of those with CIN1. Among CIN2+ patients, the percentage with a first sexual encounter at ≤20 years old was significantly different from that of those with CIN1. The percentage of CIN2+ patients with ≥2 sexual partners was significantly different from that of CIN1- patients., Results: The plasma miRNA-214, -34a, and -200a expression levels were decreased in patients with more severe cervical lesions. Plasma miRNA levels in CIN1- patients were significantly different from those in CIN2+ patients. The kappa values for miRNA-21, - 214, -34a and -200a in tissue versus plasma were 0.7122, 0.9998, 0.8986 and 0.7458, respectively. The sensitivity of each biomarker for detecting CIN2 was calculated, and ROC curves of the four miRNA biomarkers were drawn. The AUC of the four plasma miRNAs was greater than 0.5, with the AUC of miRNA-21 being the largest at 0.703. The plasma miRNA expression levels exhibited at least one tie between CIN1 and CIN2. The AUCs for miRNA-21, -34a, -200a and - 214 were 0.613, 0.508, 0.615 and 0.505, respectively., Conclusions: Changes in plasma miRNA-21, - 214, -34a and -200a levels were associated with cervical lesion severity. The plasma miRNA levels in CIN1- subjects were significantly different from those in CIN2+ subjects. This analysis may help in detection of high-grade cervical lesions.

Aim: To evaluate and identify the risk factors for abnormal menstruation after radical trachelectomy., Methods: This study included 58 patients who underwent radical trachelectomy at our hospital between April 2005 and January 2018. Patients were divided into groups of those with no change in postoperative menstruation (regular [R] group; n = 46) and those with abnormal menstruation such as amenorrhea or hypomenorrhea (irregular [I] group; n = 12). The perioperative characteristics and fertility of the groups were compared retrospectively. The data were statistically analyzed using Student's t-test, Fisher's exact test and Mann-Whitney U test for univariate analysis and logistic regression analysis for multivariate analysis, with the level of statistical significance set at P < 0.05., Results: Based on Federation of Gynecology and Obstetrics staging, 54 patients had stage IB1, 2 had stage IB2 and 2 had stage IIA1 cervical cancer. Eight patients received neoadjuvant chemotherapy. Pretreatment tumor size, residual uterine cavity length and neoadjuvant and postoperative chemotherapy use were not significantly different between the groups. Abnormal menstruation was significantly more common in patients with postoperative pelvic infection (R group, 13.0%; I group, 58.3%) and cervical stenosis (R group, 15.2%; I group, 58.3%)., Conclusion: To maintain healthy menstruation even after radical trachelectomy, it is important to prevent postoperative pelvic infection and cervical stenosis., (© 2019 Japan Society of Obstetrics and Gynecology.)

Recent large-scale genomics studies of human papillomaviruses (HPVs) have shown a high level of genomic variability of HPV16, the most prevalent genotype in HPV-associated malignancies, and provided new insights into the biological and clinical relevance of its genetic variations in cervical cancer development. Here, we performed deep sequencing analyses of the viral genome to explore genetic variations of HPV16 that are prevalent in Japan. A total of 100 complete genome sequences of HPV16 were determined from cervical specimens collected from Japanese women with cervical intraepithelial neoplasia and invasive cervical cancer, or without cervical malignancies. Phylogenetic analyses revealed the variant distribution in the Japanese HPV16 isolates; overall, lineage A was the most prevalent (94.0%), in which sublineage A4 was dominant (52.0%), followed by sublineage A1 (21.0%). The relative risk of sublineage A4 for cervical cancer development was significantly higher compared to sublineages A1/A2/A3 (odds ratio = 6.72, 95% confidence interval = 1.78-28.9). Interestingly, a novel cluster of variants that branched from A1/A2/A3 was observed for the Japanese HPV16 isolates, indicating that unique HPV16 variants are prevalent among Japanese women.

Less than 10 deliveries via cervicovaginal fistula (CVF) with closed cervical os were reported so far. In the majority of cases, the patients had a history of induced abortions. The CVF was usually recognized due to postpartum hemorrhage. The facilitating role of prostaglandins used for labor induction was supposed. In all cases, the babies remained unaffected by the delivery route. We report a new case of a 37-year-old gravida 2, para 0, with a history of a paracervical tear following a first trimester abortion 11 years ago. The abortion and the laceration were not reported in the current obstetrical documentation. After labor induction using oral misoprostol in the 41 + 5 weeks of pregnancy, the patient delivered a healthy baby through a left-sided CVF, which imposed as bleeding paracervical laceration, 6 cm in diameter, extending to the vaginal fornix in the 3 o'clock position. The cervical os was only 1-1.5 cm dilated and imposed as an inelastic band ("squid ring") in the 9 o'clock position. The laceration was sutured under spinal anesthesia. The patient recovered quickly, and the postpartum hemoglobin drop was 2.8 g/dl. In conclusion, the possibility of CVF should be considered in women with a history of induced abortion.

Introduction: Several types of photosensitizers such as 5-aminolevulinic acid are progenitors of protoporphyrin IX (PpIX). PpIX accumulates in cancer cells and has photosensitivity. Based on these characteristics, they are used in photodynamic diagnosis (PDD) and photodynamic therapy (PDT). These methods have recently been applied to gynecologic malignant diseases. Here, we review articles on clinical applications of PDD and PDT for these diseases., Materials and Methods: A systematic literature search in Pubmed was performed with a combination of keywords to collect the articles., Result: There were eight articles on PDT for uterine cervical diseases, including one study that included patients with cervical cancer. The disease remission rate ranged from 31.6% to 100%. PDD under hysteroscopy had positive effects on endometrial cancer, endometrial hyperplasia and secretory endometrial tissue, and 7 of 11 patients were able to become pregnant after PDT for endometrial cancer. For ovarian cancer, the sensitivity and specificity of clinical PDD were high., Discussion: There is a need to improve the disease remission rate in uterine cervical diseases, and application of PDT for cervical cancer should be considered. For endometrial cancer, the risks and benefits of PDD that should be compared with those of hysteroscopy using narrow band imaging, which already has been shown to have high efficacy and few side effects. For ovarian cancer, it will be necessary to collect more data to evaluate the effect of PDD on overall survival., Conclusion: PDD and PDT can contribute to diagnosis and therapy in clinical practice for gynecologic malignant diseases., (Copyright © 2018 Elsevier B.V.

Importance: Cervical stenosis is a challenging clinical entity that requires prompt identification and management in order to avoid iatrogenic injury at the time of endocervical canal cannulation., Objective: The aim of this study was to identify cervical stenosis and discuss associated etiologies, risk factors, and review medical and surgical approaches for overcoming cervical stenosis., Evidence Acquisition: Computerized searches of MEDLINE and PubMed were conducted using the key words "cervix", "cervical stenosis," "embryo transfer," "hysteroscopy complications," "misoprostol," and "ultrasound." References from identified sources were manually searched to allow for a thorough review. Data from relevant sources were compiled to create this review., Results: Transcervical access to the uterine cavity is frequently required for procedures such as hysteroscopy, dilation and curettage, endometrial biopsy, sonohysterogram, hysterosalpingogram, intrauterine insemination, embryo transfer in those undergoing in vitro fertilization, and insertion of intrauterine devices. These procedures can become complicated when difficult cannulation of the endocervical canal is encountered. Management strategies include preprocedural use of cervical-ripening agents or osmotic dilators, ultrasound guidance, no-touch vaginoscopy, manual dilatation, and hysteroscopic resection of the obstructed endocervical canal., Conclusions and Relevance: Cervical stenosis is associated with iatrogenic complications that can result in significant patient morbidity. In patients undergoing in vitro fertilization, difficult embryo transfer is associated with lower pregnancy rates. The clinician should carefully consider the patient's menopausal status, risk factors, and symptoms in order to anticipate difficult navigation of the endocervical canal. Various medical and surgical management strategies, including hysteroscopic resection, can be used to overcome the stenotic cervix.

Introduction: To evaluate the internal quality control indicators and quality management programme in a university cytopathology laboratory., Methods: All results of conventional cervical smears tests (taken from the SISCAN, the Brazilian cervical cancer screening system) of women aged ≥15 years at the time of Papanicolaou smear specimen collection during January 2007-December 2014 were included. The final results of the cytopathology were classified in accordance with the Bethesda System. The variables included in the database were the woman's name, date of birth, and age at the time of sampling (15-30, 31-40 and older than 40 years)., Results: In this period, 50 286 cytopathology examinations were carried out. Of these, 44 386 (91.34%) were negative for malignancy or unsatisfactory and 4209 (8.66%) presented epithelial abnormalities. The percentage of the tests consistent with atypical squamous cells (ASC) between satisfactory examinations was 4.12%; the percentage of tests compatible with ASC among abnormal examinations was 47.87%; the ASC/squamous intraepithelial lesion) ratio was 0.97 and the percentage of high-grade squamous intraepithelial lesion among satisfactory tests was 2.21%, and the 5-year retrospective review identified 4.97% of false-negative results., Conclusion: All rates obtained were consistent over the years and within the recommended values by Federal Regulation of Brazil. This demonstrates the efficacy of our established internal quality monitoring and continuing education, reflecting the commitment of the team involved in the release of smear reports., (© 2018 John Wiley & Sons Ltd.)

Objective: To compare the quality of tissue from punch biopsy forceps (PB group) with round loop electrode (LE group) in colposcopically directed biopsy along with the evaluation of pain associated with each procedure., Methods: Patients with abnormal cervical cytologic results and abnormal colposcopic findings were enrolled into a randomized trial into either a PB group or LE group. The quality of tissue was evaluated in regards to the size of tissue, site of tissue, and tissue damage. Each quality had 1 to 3 points and the sum of each quality contributed to the total tissue score that ranged from 3 to 9. Pain associated with each procedure was assessed by a visual analog scale (VAS). This was a clinical trial study and was registered at www.clinicaltrials.in.th (Identifier: TCTR20160404001)., Results: Ninety-six women who met all eligibility requirements were enrolled in the study. Forty-eight patients were randomly assigned to the PB group and 48 patients were randomized into the LE group. The characteristics of the patients were similar between the 2 groups with the exception of the median age. The median total tissue score was 8 points in the LE group which was more than the median of 7 points in the PB group with a statistically significant difference (p=0.014). However, the median VAS pain score in both groups was 3.4 (p=0.82)., Conclusion: The quality of cervical tissues obtained from biopsy with a round loop electrode was better than the punch biopsy forceps with no difference in the level of pain., Competing Interests: No potential conflict of interest relevant to this article was reported., (Copyright © 2018.

Despite being a commonly encountered infection, the clinical diagnosis of tuberculosis of the uterine cervix is elusive. Though a straightforward diagnosis on tissue sections, identification of typical features of tubercular infection on cervical Pap samples is challenging. In our experience, the infrequent pale staining collections of epithelioid cells are difficult to pick up on Pap stained smears, particularly LBC samples. In this series, 2 of the three samples were reported as atypical squamous cells of undetermined significance while 1 was reported as inflammatory at the initial diagnosis. Scattered Langhans' type giant cells may be seen as a subtle clue which should prompt the search for epithelioid cell granulomas. These cases may have a mass lesion clinically while no obvious signs of malignancy on the cervical samples., (© 2017 Wiley Periodicals, Inc.)

Adenocarcinoma of the cervix is less common than squamous cell carcinoma, although its relative prevalence is increasing. Oncogenic (high-risk) human papillomavirus (HPV) infection is implicated in the development of approximately 90% of all cervical adenocarcinomas. Of the remaining non-HPV associated tumours, the most frequent is gastric-type adenocarcinoma (GAS), which is recognised by the World Health Organization as a form of mucinous adenocarcinoma of the cervix. Minimal deviation adenocarcinoma (MDA) of mucinous type (adenoma malignum) is considered an extremely well differentiated variant of GAS and is encompassed within the category of GAS. The concept of gastric-type cervical glandular lesions has emerged over recent decades and our understanding of the full spectrum of benign, premalignant and malignant lesions is still evolving. Established benign lesions, which are rare, include simple gastric metaplasia and lobular endocervical glandular hyperplasia (LEGH) (complex gastric metaplasia). Postulated premalignant lesions comprise atypical LEGH and gastric-type adenocarcinoma in situ (gAIS); these are probably related lesions for which the umbrella term 'gAIS' has been proposed. The term 'gastric-type' derives from the morphological resemblance of the glandular epithelium to that seen in the stomach and pancreaticobiliary tree; intestinal metaplasia with goblet cells and neuroendocrine cells are present in some cases. A gastric immunophenotype has been demonstrated using markers of pyloric gland mucin, MUC6 and HIK1083. Uncommonly, gastric-type cervical glandular lesions involve multiple sites in the female genital tract and it may be problematic to discern whether these represent independent synchronous or metastatic lesions. There is also an association between gastric-type cervical lesions and Peutz-Jeghers syndrome. Awareness of the spectrum of gastric-type lesions is important, as the diagnostic features of both gAIS and GAS, particularly well differentiated examples, may be subtle, and p16 immunohistochemistry is usually negative. GAS has a much poorer prognosis than HPV-associated cervical adenocarcinoma, with propensity for presentation at advanced stage and wide dissemination to unusual sites such as the ovary, omentum and peritoneum. Although uncommon, GAS is likely to increase in relative prevalence with the introduction of HPV vaccination and precursor lesions will not be detected by primary HPV-based screening programs., (Copyright © 2017 Royal College of Pathologists of Australasia.

HPV and Chlamydia trachomatis are the most common causes of sexually transmitted diseases worldwide. Most infections are asymptomatic and left untreated lead to severe reproductive tract sequelae such as cervical cancer and infertility. Interestingly, C. trachomatis may also increase the susceptibility to HPV infection as well as contribute to viral persistence. Recently, a growing body of evidence has suggested that the composition of the cervico-vaginal microbiota plays a key role in the susceptibility and outcome of genital infections caused by several pathogens, including HPV and C. trachomatis. The aim of our study was to undertake a metagenomic analysis of sequenced 16s rRNA gene amplicons to characterize the cervical microbiota from asymptomatic women with HPV/C. trachomatis co-infection. The composition of the cervical microbiota from HPV-positive or C. trachomatis-positive women was also analysed. The main finding of our study showed that the cervical microbiota in HPV/C. trachomatis co-infected women had a higher microbial diversity than the cervical microbiota in healthy controls (p<0.05). In addition, Aerococcus christensenii was associated with C. trachomatis infection. In conclusion, the increased cervical microbial diversity observed in HPV/C. trachomatis co-infected women and the detection of potential microbiological biomarkers of C. trachomatis infection will open the way to innovative approaches that may be helpful to identify women at risk of co-infection.

Mullerian duct anomalies (MDAs) are congenital defects of the female genital system that arise from abnormal embryological development of the Mullerian ducts. Septate uterus is the most common, resulting from incomplete resorption of the medial septum after fusion of the Mullerian ducts. Two main types of septate uterus exist, including septa that extend completely or partially from the uterine fundus to the cervical os. The combination of a uterine septum with a double cervix has been previously described; however, in most cases the septum was complete. We present a case of a 23-year-old female with a partial uterine septum and a double cervix. We refer to this atypical MDA as "uterus septus subtotalis bicollis". The description, characterization, and diagnosis of rare MDAs is important as they imply distinct therapeutic modalities., (© 2018 by the Association of Clinical Scientists, Inc.)

Purpose: Cost-effectiveness analyses (CEAs) of screening can be highly sensitive to the health-related quality of life (HRQoL) effects of screen tests and subsequent treatment. Accordingly, accurate assessment of HRQoL is essential. We reviewed the literature regarding HRQoL in cervical prevention and management in order to appraise the current evidence regarding this important input to CEA., Methods: We searched the MEDLINE, Scopus and EconLit databases for studies that estimated HRQoL in cervical cancer prevention and management published January 1995-December 2015. The primary inclusion criterion was for studies that assess HRQoL using the EQ-5D. Data were abstracted from eligible studies on setting, elicitation group, sample size, elicitation instruments, health state valuations, study design and follow-up. We assessed the quality and comparability of the studies with a particular focus on the HRQoL reported across states and groups., Results: Fifteen papers met the inclusion criteria. Most used patient elicitation groups (n = 11), 2 used the general public and 2 used a mix of both. Eight studies were cross-sectional and seven were longitudinal. Six studies used both the EQ-5D-3L and the EQ-VAS together with other measures of overall HRQoL or condition-specific instruments. Extensive heterogeneity was observed across study characteristics., Conclusions: Our results reveal the challenges of sourcing reliable estimates of HRQoL for use in CEAs of cervical cancer prevention and treatment. The EQ-5D appears insufficiently sensitive for some health states. A more general problem is the paucity of HRQoL estimates for many health states and their change over time.

Background: Preterm birth is in quantity and in severity the most important topic in obstetric care in the developed world. Progestogens and cervical pessaries have been studied as potential preventive treatments with conflicting results. So far, no study has compared both treatments., Methods/design: The Quadruple P study aims to compare the efficacy of vaginal progesterone and cervical pessary in the prevention of adverse perinatal outcome associated with preterm birth in asymptomatic women with a short cervix, in singleton and multiple pregnancies separately. It is a nationwide open-label multicentre randomized clinical trial (RCT) with a superiority design and will be accompanied by an economic analysis. Pregnant women undergoing the routine anomaly scan will be offered cervical length measurement between 18 and 22 weeks in a singleton and at 16-22 weeks in a multiple pregnancy. Women with a short cervix, defined as less than, or equal to 35 mm in a singleton and less than 38 mm in a multiple pregnancy, will be invited to participate in the study. Eligible women will be randomly allocated to receive either progesterone or a cervical pessary. Following randomization, the silicone cervical pessary will be placed during vaginal examination or 200 mg progesterone capsules will be daily self-administered vaginally. Both interventions will be continued until 36 weeks gestation or until delivery, whichever comes first. Primary outcome will be composite adverse perinatal outcome of perinatal mortality and perinatal morbidity including bronchopulmonary dysplasia, intraventricular haemorrhage grade III and IV, periventricular leukomalacia higher than grade I, necrotizing enterocolitis higher than stage I, Retinopathy of prematurity (ROP) or culture proven sepsis. These outcomes will be measured up until 10 weeks after the expected due date. Secondary outcomes will be, among others, time to delivery, preterm birth rate before 28, 32, 34 and 37 weeks, admission to neonatal intensive care unit, maternal morbidity, maternal admission days for threatened preterm labour and costs., Discussion: This trial will provide evidence on whether vaginal progesterone or a cervical pessary is more effective in decreasing adverse perinatal outcome in both singletons and multiples., Trial Registration: Trial registration number: NTR 4414 . Date of registration January 29th 2014.

Papillomavirus infection is one of the most common sexually transmitted infections. The aim of the study was to study the etiologic significance of the papillomavirus infection in the development of background diseases of the cervix and neoplasia. Under observation were 62 patients aged 18 to 55 years infected with human papillomavirus. All patients underwent complex clinical and anamnestic, laboratory and instrumental examination. Also, a review and advanced colposcopy was performed. As a result of the study, 53 (85.4%) women under observation were found to have various pathologies of the cervix. Dysplasia of mild degree (CIN 1 degree) was found in 12 (57.1%), moderate dysplasia (CIN 2 degree) - in 9 (42.9%) women. With further examination, it was found that patients along with dysplasia of varying severity had concomitant pathology of the cervix uteri. Cervical dysplasia was most often diagnosed in combination with another pathology of the cervix, which accounted for 85.7% of cases. It has been established that squamous epithelial lesion of the cervix is most often a consequence of late diagnosis and an untreated background process. At the same time, modern diagnostics requires a whole range of diagnostic measures to establish a diagnosis in the early stages of development and conduct differential diagnosis of a benign or malignant process.

Objective: To demonstrate an approach to the hysteroscopic management of a stenotic cervix., Design: Step-by-step explanation of the techniques using video and animation (educational video)., Setting: Academic tertiary level referral center., Patient(s): Patients with cervical stenosis, inclusive of both reproductive age and postmenopausal women. Gynecologists require intrauterine access for many procedures, but a stenotic cervix can obstruct surgery. Blind dilation of a stenotic cervix can lead to a cervical laceration or uterine perforation, with concomitant complications., Intervention(s): The hysteroscopic management of a stenotic cervix includes optimizing the surgical environment, performing vaginoscopy and "no-touch" hysteroscopy, and revision of the cervical canal. Revision can be performed using microscissors, micrograspers, or a cutting loop electrode. Partial cervical canal excision to aid in hysteroscopy access should be reserved in women who are not interested in future pregnancy or those who are postmenopausal. Outpatient hysteroscopy uses smaller instruments and shows operative success with patient satisfaction. Although these techniques are demonstrated in an outpatient hysteroscopy setting, they can be adapted for use in an operating theater., Main Outcome Measure(s): The individual steps and approach are emphasized., Result(s): Intrauterine access can be achieved with various techniques., Conclusion(s): The "see-and-treat" approach demonstrated in this video can allow access into the uterine cavity despite a stenotic cervix., (Copyright © 2017 American Society for Reproductive Medicine.

Purpose  To evaluate the effect of mesenchymal stem cells (MSCs) on fertility in experimental retrocervical endometriosis. Methods  A total of 27 New Zealand rabbits were divided into three groups: endometriosis, in which endometrial implants were created; mesenchymal, in which MSCs were applied in addition to the creation of endometrial implants; and control, the group without endometriosis. Fisher's exact test was performed to compare the dichotomous qualitative variables among the groups. The quantitative variables were compared by the nonparametric Mann-Whitney and Kruskal-Wallis tests. The Mann-Whitney test was used for post-hoc multiple comparison with Boniferroni correction. Results  Regarding the beginning of the fertile period, the three groups had medians of 14 ± 12.7, 40 ± 5, and 33 ± 8.9 days respectively ( p  = 0.005). With regard to fertility (number of pregnancies), the endometriosis and control groups showed a rate of 77.78%, whereas the mesenchymal group showed a rate of 11.20% ( p  = 0.015). No differences in Keenan's histological classification were observed among the groups ( p  = 0.730). With regard to the macroscopic appearance of the lesions, the mesenchymal group showed the most pelvic adhesions. Conclusion  The use of MSCs in endometriosis negatively contributed to fertility, suggesting the role of these cells in the development of this disease., Competing Interests: Declaration of Conflicting Interests: The Authors have no conflicts of interest to declare., (Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.)

Purpose: Most of the existing studies on postcoital bleeding (PCB) in Western countries. To date, no study has focused on the various PCB-related comorbidities in Taiwan women. This work aims to analyze and compare the presence or absence of PCB among Taiwanese women with gynecological comorbidity., Methods: This study is a population-based retrospective cohort investigation. Outpatients with PCB after the index date were considered. A total of 2377 female patients with PCB (ICD-9 626.7) were identified using a nationwide outpatient sample from 2001 to 2010. For comparison, 7131 cases were randomly matched with the study group in terms of gender and age., Results: The PCB incidence rate was 39-59 cases/100,000 Taiwanese women, with mean age (±SD) of 36.74 ± 10.79 years, median age of 36 years, and mode age of 29 years. Women with PCB exhibited 1.47-fold risk of cervical dysplasia and 1.59-fold risk for malignant neoplasm of cervix. Young women with PCB showed high risk of cervical cancer. The most common benign diseases among PCB- related comorbidities were cervical erosion and ectropion (20.66%), followed by vaginitis and vulvovaginitis (19.18%). Comparison between PCB and non-PCB groups indicated several significant high-risk comorbidities including cervical polyps, cervical erosion, leukoplakia of cervix, intrauterine contraceptive device, cervicitis, vaginitis, menopause, dyspareunia, and vulvodynia., Conclusions: This study provides evidence that PCB-related comorbidities manifested benign diseases (51.58%), lower genital tract infection (46.11%), and cervical cancer (2.31%). Thus, healthcare providers must ensure that appropriate routine screening tests and counseling are given to women with PCB.

Object: Degenerative cervical myelopathy [DCM] is a disabling and increasingly prevalent condition. Variable reporting in interventional trials of study design and sample characteristics limits the interpretation of pooled outcomes. This is pertinent in DCM where baseline characteristics are known to influence outcome. The present study aims to assess the reporting of the study design and baseline characteristics in DCM as the premise for the development of a standardised reporting set., Methods: A systematic review of MEDLINE and EMBASE databases, registered with PROSPERO (CRD42015025497) was conducted in accordance with PRISMA guidelines. Full text articles in English, with >50 patients (prospective) or >200 patients (retrospective), reporting outcomes of DCM were deemed to be eligible., Results: A total of 108 studies involving 23,876 patients, conducted world-wide, were identified. 33 (31%) specified a clear primary objective. Study populations often included radiculopathy (51, 47%) but excluded patients who had undergone previous surgery (42, 39%). Diagnositic criteria for myelopathy were often uncertain; MRI assessment was specified in only 67 (62%) of studies. Patient comorbidities were referenced by 37 (34%) studies. Symptom duration was reported by 46 (43%) studies. Multivariate analysis was used to control for baseline characteristics in 33 (31%) of studies., Conclusions: The reporting of study design and sample characteristics is variable. The development of a consensus minimum dataset for (CODE-DCM) will facilitate future research synthesis in the future.

The authors describe a rare case of a giant nabothian cyst in a 52-year-old woman. The patient had a history of massive abnormal uterine bleeding after heavy physical work. A giant cystic mass, originating from the cervix, was found completely filling the upper third of the vagina. The authors combined hysteroscopy examination with ultrasound to assess the cystic mass' localization, origin, and relationship with other organs. With the tentative diagnosis of a giant nabothian cyst, the patient was treated with a simple cervical incision and local drainage. The patient recovered well postoperatively and the diagnosis was confirmed through pathological examination.

Endocervical polyps are common benign lesions which rarely result in diagnostic problems, although a variety of alterations occasionally complicate histologic interpretation. We report an unusual, and not previously described, finding of florid "epidermal" metaplasia with keratinization and extensive formation of skin appendages structures (sebaceous and sweat glands and hair follicles) within an endocervical polyp. The features closely resembled an epidermal inclusion cyst. We speculate on the possible pathogenesis of this rare phenomenon and review unusual findings in endocervical polyps.

Cervical amoebiasis is an extremely rare diagnosis with only a small number of published case reports. This disease may present as cervical growth mimicking cervical carcinoma. Owing to the similarity of the clinical presentation of bleeding per vagina and per speculum examination showing growth or ulcers, definitive diagnosis is made on microscopic examination only. We present a rare case of cervical amoebiasis in a 28-year-old, multiparous female who presented with a history of vaginal bleeding. The patient was treated with metronidazole and diloxanide furate, after which she recovered. Awareness of this rare entity is important for clinical suspicion and for the pathologist to identify trophozoites and make a diagnosis, preventing unwarranted investigations. Accurate diagnosis also facilitates quick management of a patient; as this disease is an infective pathology that can easily be treated by antibiotics., (Copyright © 2015 King Saud Bin Abdulaziz University for Health Sciences.

Background: Cervical dilation in the second trimester is associated with a greater than 90% rate of spontaneous preterm birth and a poor perinatal prognosis., Objective: To compare the perinatal outcomes of twin pregnancies with dilated cervix in women who underwent either cerclage or expectant management., Study Design: Retrospective cohort study of asymptomatic twin pregnancies identified with cervical dilation of ≥1 cm at 16-24 weeks (1997-2014) at 7 institutions. Exclusion criteria were genetic or major fetal anomaly, multifetal reduction at >14 weeks, prior cerclage placement, monochorionic-monoamniotic placentation, active vaginal bleeding, labor, chorioamnionitis, elective termination of pregnancy, or medically indicated preterm birth. The primary outcome was incidence of spontaneous preterm birth at <34 weeks. Secondary outcomes were incidence of spontaneous preterm birth at <32 weeks, <28 weeks, and <24 weeks; perinatal mortality; and composite adverse neonatal outcome (respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and sepsis)., Results: A total of 76 women with twin pregnancy with dilated cervix of 1.0-4.5 cm were managed with either cerclage (n = 38) or expectant management (n = 38). Demographic characteristics were not significantly different. Analysis was adjusted for amniocentesis and vaginal progesterone use. In the cerclage group, 29 women (76%) received prophylactic indomethacin and 36 (94%) received prophylactic antibiotics, whereas the expectant management group did not. Interval from time at diagnosis of open cervix to delivery in the cerclage group was 10.46 ± 5.6 weeks vs 3.7 ± 3.2 weeks in the expectant management group, with a mean difference of 6.76 weeks (95% confidence interval [CI], 4.71-8.81). There were significant decreases in spontaneous preterm birth at <34 weeks (52.6% vs 94.7%; adjusted odds ratio [aOR], 0.06; 95% CI, 0.03-0.34), at <32 weeks (44.7% vs 89.4%; aOR, 0.08; 95% CI, 0.03-0.34); at <28 weeks (31.6% vs 89.4%; aOR, 0.05; 95% CI, 0.01-0.2); and at <24 weeks (13.1% vs 47.3%; aOR, 0.17; 95% CI, 0.05-0.54). There were also significant reductions in perinatal mortality (27.6% vs 59.2%; aOR, 0.24; 95% CI, 0.11-0.5), neonatal intensive care unit admission (75.9% vs 97.6%; aOR, 0.07; 95% CI, 0.01-0.66), and composite adverse neonatal outcome (33.9% vs 90.5%; aOR, 0.05; 95% CI, 0.01-0.21)., Conclusion: Cerclage, indomethacin, and antibiotics in twin pregnancies with dilated cervix ≥1 cm before 24 weeks were associated with significant longer latency period from diagnosis to delivery (6.7 weeks), decreased incidence of spontaneous preterm birth at any given gestational age, and improved perinatal outcome when compared with expectant management., (Copyright © 2016 Elsevier Inc.

The adult uterine cervix may exhibit a wide variety of pathologic conditions that include benign entities (eg, cervicitis, hyperplasia, nabothian cysts, cervical polyps, leiomyomas, endometriosis, and congenital abnormalities) as well as malignant lesions, particularly cervical carcinoma. In addition, lesions that arise in the uterine body may secondarily involve the cervix, such as endometrial carcinoma and prolapsed intracavitary masses. Many of these conditions can be identified and characterized at ultrasonography (US), which is considered the first-line imaging examination for the female pelvis. However, examination of the cervix is often cursory during pelvic US, such that cervical disease may be overlooked or misdiagnosed. Transabdominal US of the cervix may not afford sufficient spatial resolution to depict cervical disease in many patients; therefore, endovaginal US is considered the optimal technique. Use of supplemental imaging techniques, particularly the application of transducer pressure on the cervix, may be helpful. This review describes the normal appearance of the cervix at US, the appearance of cervical lesions and conditions that mimic abnormalities at US, and optimal US techniques for evaluation of the cervix. This information will help radiologists detect and diagnose cervical abnormalities more confidently at pelvic US. Online supplemental material is available for this article., ((©)RSNA, 2016.)

Study Objective: To report the combined hysteroscopic and laparoscopic treatment of a complete septate uterus with unilateral cervical aplasia (class U2bC3V0/ESHRE/ESGE classification) and isolated mullerian remnants., Design: Step-by-step presentation of the surgical treatment (Canadian Task Force classification 4)., Setting: Complete septate uterus with unilateral cervical aplasia (formally Robert's uterus) is characterized by the presence of a uterine septum completely dividing the endometrial cavity into an obstructed hemicavity and a contralateral nonobstructing hemicavity connected normally to the existing cervix. It has always been described as isolated without any associated anomaly., Patient: A 30-year-old woman was referred to our department for dysmenorrhea and primary infertility. Hysterosalpingography showed the presence of a right (RT) hemiuterus with a patent fallopian tube; further evaluation with 2- and 3-dimensional ultrasound and magnetic resonance imaging showed an externally normal-appearing uterus, a right normal hemicavity connected normally with the existed cervix and, a left hemicavity fully divided from the right one by a complete septum and not connected with the cervix. Interestingly, a peculiar complex mass with cystic areas, attached posterolaterally from the left side to the uterine wall at the level of the isthmus and the upper cervix, was also diagnosed., Interventions: The study protocol was approved by our local institutional review board. During outpatient hysteroscopy, a right uterine hemicavity with a single ostium was identified without any communication with the left hemicavity. The patient was then scheduled for combined laparoscopic and hysteroscopic treatment. During laparoscopy, a normal uterine body with multiple myomas and a pseudocystic lesion attached posteriorly and left laterally to the uterus at the level of the isthmus and the upper cervix were shown; no communication between the cystic part of that lesion and the isthmus or the cervicovaginal canal was observed. During hysteroscopy, a longitudinal incision of the septum with a 5F bipolar electrode was performed; the left hemicavity was opened, and the corresponding tubal ostium was identified. The pseudocystic lesion was then excised after opening and sent for pathological analysis; the defect was closed with interrupted intracorporeal knots., Measurements and Main Results: A single normal endometrial cavity with both tubal ostia was obtained, thus restoring obstruction by unification of the uterine cavity. A histologic report of the removed pseudocystic lesion was compatible with the diagnosis of mullerian remnants. A follow-up hysteroscopy 3 months after showed a normal uterine cavity without postsurgical adhesions., Conclusion: The use of 3-dimensional ultrasound and magnetic resonance imaging in combination with the new ESHRE/ESGE classification system gives the opportunity to obtain a precise representation of the female genital anatomy even in the presence of complex anomalies. Although a septate uterus with unilateral cervical aplasia has been already described, the presence of mullerian remnants is a rare entity associated with cyclic pelvic pain, thus needing adequate recognition and treatment. The combined hysteroscopic and laparoscopic approach offers a unique opportunity for the treatment of complex anomalies., (Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.)

Introduction: a tendency of increasing incidence of the cervix uteri precancer and cancer in women of reproductive age is noticed recently being related to the growth of number of the sexually-transmitted infections. The cervix uteri pathology incidence in women of fertile age is 20-25%., Aim: to study the specific features of the cytological and colposcopical pattern in pregnant patients with benign cervix uteri pathology in the anamnesis and the character of its change post partum., Material and Methods: we have examined 195 women during their pregnancy and 3-5 months post partum. All pregnant women, alongside with generally accepted clinical and laboratory examinations, were subjected to the simple and extended colposcopy, cytology of the targeted smears and, according to indications, the histological studies of bioptate., Results: according to the results of the colcoscopical studies and the signs of the cervix uteri pathology found, the patients were divided into several groups. A control group included 49 pregnant women. The clinical and instrumental examination of 146 women with cervix uteri pathology has been carried out both during pregnancy and post partum., Conclusions: the structure of the clinical forms of benign and premalignant changes in the cervix uteri epithelium in pregnant patients has been found. Specific features of the cytological and colposcopical pattern in pregnant patients with benign cervix uteri pathology in anamnesis have been studied. The relationship between the parity of pregnancy, delivery, route of delivery and regress of both benign and premalignant changes in the cervix uteri epithelium 3-5 months post partum has been determined.

Introduction: A placental site nodule (PSN) is a remnant of intermediate trophoblast (extravillous trophoblast, EVT) from a previous pregnancy. Usually, this a benign lesion, which once removed, does not require any treatment and does not recur. Although this lesion is related to pregnancy, it may be detected many months or several years after the pregnancy from which it resulted. The lesion represents a degenerative process of EVT. Especially in tissue obtained from curettage, can microscopically mimic aggressive lesions of intermediate trophoblast, such as placental site trophoblastic tumor (PSTT) and epithelioid trophoblastic tumor (ETT), and in an unusual location can pose problems in differential diagnosis with other malignancies, as in the present cervical example., Case Report: A 36-year-old female, gravida 2, para 1, with a history of early spontaneous abortion two years prior, was submitted to a cervical smear for abnormal uterine bleeding, which showed a cervical high squamous intraepithelial lesion (HSIL) with extension to the endocervical cells. Histologic examination of the endocervical curettage revealed haphazardly distributed fragments of tissue, showing extensive hyalinization and cells of different size with indistinct outlines, organized in small groups, singly, or in cords. Mitotic figures were absent. Immunohistochemical analysis revealed focal positivity to cytokeratin 8 (CK8) and placental alkaline phosphatase and negativity to high molecular weight cytokeratin. The Ki-67 index was low. As a result, the morphological and immunohistochemical findings led to the diagnosis of a PSN., Conclusion: Diagnosis of a PSN in an unusual location also can pose problems in differential diagnosis with other malignancies, as in the present cervical example. In the present case, the cervical location and the association with HSIL might suggest an erroneous diagnosis of cervical invasive squamous carcinoma. Clinical and pathological data, with immunohistochemical study, are mandatory for a correct diagnosis of this lesion.

We conducted a systematic review and meta-analysis to assess the safety and effectiveness of robotic vs laparoscopic hysterectomy in women with benign uterine disease, as determined by randomized studies. We searched MEDLINE, EMBASE, the Cochrane Library, ClinicalTrials.gov, and Controlled-Trials.com from study inception to October 9, 2014, using the intersection of the themes "robotic" and "hysterectomy." We included only randomized and quasi-randomized controlled trials of robotic vs laparoscopic hysterectomy in women for benign disease. Four trials met our inclusion criteria and were included in the analyses. We extracted data, and assessed the studies for methodological quality in duplicate. For meta-analysis, we used random effects to calculate pooled risk ratios (RRs) and weighted mean differences. For our primary outcome, we used a modified version of the Expanded Accordion Severity Grading System to classify perioperative complications. We identified 41 complications among 326 patients. Comparing robotic and laparoscopic hysterectomy, revealed no statistically significant differences in the rate of class 1 and 2 complications (RR, 0.66; 95% confidence interval [CI], 0.23-1.89) or in the rate of class 3 and 4 complications (RR, 0.99; 95% CI, 0.22-4.40). Analyses of secondary outcomes were limited owing to heterogeneity, but showed no significant benefit of the robotic technique over the laparoscopic technique in terms of length of hospital stay (weighted mean difference, -0.39 day; 95% CI, -0.92 to 0.14 day), total operating time (weighted mean difference, 9.0 minutes; 95% CI, -31.27 to 47.26 minutes), conversions to laparotomy, or blood loss. Outcomes of cost, pain, and quality of life were reported inconsistently and were not amenable to pooling. Current evidence demonstrates neither statistically significant nor clinically meaningful differences in surgical outcomes between robotic and laparoscopic hysterectomy for benign disease. The role of robotic surgery in benign gynecology remains unclear., (Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.)

Objective: To estimate the combined value of fetal cerebral Doppler examination and Bishop score for predicting perinatal outcome after labor induction for small-for-gestational-age (SGA) fetuses in the presence of normal umbilical artery Doppler recordings., Methods: We conducted a cohort study in two tertiary centers, including 164 women with normal umbilical artery Doppler recordings who underwent induction of labor because of an estimated fetal weight < 10(th) percentile. The fetal middle cerebral artery pulsatility index and cerebroplacental ratio (CPR) were obtained in all cases within 24 h before induction. Cervical condition was assessed at admission using the Bishop score. A predictive model for perinatal outcomes was constructed using a decision-tree analysis algorithm., Results: Both a very unfavorable cervix, defined as a Bishop score < 2, (odds ratio (OR), 3.18; 95% CI, 1.28-7.86) and an abnormal CPR (OR, 2.54; 95% CI, 1.18-5.61) were associated with an increased likelihood of emergency Cesarean section for fetal distress, but only the latter was significantly associated with the need for neonatal admission (OR, 2.43; 95% CI, 1.28-4.59). In the decision-tree analysis, both criteria significantly predicted the likelihood of Cesarean section for fetal distress., Conclusion: Combined use of the Bishop score and CPR improves the ability to predict overall Cesarean section (for any indication), emergency Cesarean section for fetal distress, and neonatal admission after labor induction for late-onset SGA in the presence of normal umbilical artery Doppler recordings., (Copyright © 2015 ISUOG.

Purpose: The aim of this study is to evaluate the treatment and efficacy of Badushengjigao, a traditional Chinese medicine (TCM) formula, for symptomatic cervical ectopy., Method: A patient self-selected two group comparison study was performed. One hundred patients with symptomatic cervical ectopy admitted to the Central Hospital of E-Zhou (Hubei, China) between July 2013 and July 2014 were enrolled in the study. The patients treated with Badushengjigao were the study group and the patients treated with policresulen suppository were the control group. The medicine was administered through vagina. Patients received a three-month follow-up (once a month). The treatment results were evaluated and analyzed by variance analysis and X(2) test., Results: The curative rates of the two groups with symptomatic cervical ectopy grade 1 shows no statistical significance. As for grade 2 and grade 3, the curative rates of the study group (phase 2: 72.0%; phase 3: 62.5%) are higher than that of the control group (phase 2: 44.4%; grade 3: 54.5%) with statistical difference (P < 0.05). The study group has less adverse effects (2.5 ± 1.3 days of vagina bleeding, 6 cases of abdominal pain and 2 cases of increased discharge) than the control group (12.5 ± 1.1 days of vagina bleeding, 15 cases of abdominal pain and 42 cases of increased discharge) with distinctive statistical difference (P < 0.01)., Conclusion: The TCM formula, Badushengjigao, seems to be more effective than policresulen suppositories in treating symptomatic cervical ectopy phase 2 and phase 3. We suggest that it could be used as an alternative method for symptomatic cervical ectopy treatment, but further study is needed., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Objective: To study the role of cervicovaginal infections in women with cytological reports of atypical squamous cells of undetermined significance (ASC-US)., Materials and Methods: The study included 220 women admitted to the Clinic of Microscopy, Cervicovaginal and Vulvar Pathology of the Department of Gynecology and Obstetrics of the Tor Vergata University Hospital, Rome, Italy, enrolled between October 2012 and July 2013., Results: Among the enrolled women, 105 women (47.7%) had ASC-US cytology, whereas 115 women (52.3%) had negative cytology. Microscopy showed infections more frequently in women with ASC-US than in those with negative cytology: 70.5% (74/105) vs 36% (41/115); p < .001. Cocci were present in 73.3% (77/105) of the women with ASC-US and in 43.5% (50/115) of those with negative cytology; p < .001. According to Ison score, 84% (88/105) of ASC-US was grade 0 vs 22% (25/115) of negative cytology, p < .001. Human papillomavirus was detected in 35% of the women with ASC-US. A statistically significant correlation between high pH and vaginal infections was found in women aged 20 to 29 (p = .003) and those 50 years or older in both cytological report groups; p < .001., Conclusions: Cervicovaginal infections are associated with a cytological report of ASC-US. Direct microscopy of vaginal specimens allowing immediate evaluation of the vaginal microflora and infectious agents may be a useful tool in managing women with cytological reports of ASC-US.

A 32-year-old lady came for a routine gynecological check up. Her cervical cytologic smear was reported as low grade squamous intraepithelial lesion. As a part of basic routine investigation, cervical punch biopsy was done. Astonishingly it revealed multiple rhabditiform larvae of Strongyloides stercoralis. These were curved thick with pointed end and a short buccal cavity. She did not have any history of immunosuppression including steroid therapy and was otherwise normal. Extensive review of the literature on parasites encountered in cervix yielded few case reports on strongyloides in cytologic smears, but failed to reveal any report till date on S. stercoralis found in histopathology section. Our case is probably the first in the world and the first reported from India to the best of our knowledge. We describe this case of strongyloidiasis of cervix with review of the literature on various parasites encountered in the cervix because of its rarity and also to keep this parasitic infestation as a differential diagnosis of cervical lesions.

Objective: To clarify which types of cervical polyp removed during the first and second trimester are associated with the risk of spontaneous abortion and preterm delivery., Methods: Pregnant females who underwent attempted polypectomy of cervical polyps during pregnancy and delivered singleton infants between 2005 and 2011 were evaluated. The clinical courses and outcomes of preterm delivery after polypectomy stratified according to the pathologic diagnosis of the polyps were retrospectively reviewed. The removed polyps were classified into decidual polyps and endocervical polyps., Results: The pathological diagnoses included 41 decidual polyps and 42 endocervical polyps. No malignant polyps were found. The removal of decidual polyps during pregnancy carried a higher risk of spontaneous abortion (12.2% versus 0%, p = 0.026) and preterm delivery (34.2% versus 4.8%, p = 0.001) than that of endocervical polyps. According to the multivariate logistic regression analysis, risk factors for preterm delivery before 37 weeks' gestation were the presence of decidual polyps and a history of preterm delivery., Conclusions: The risk of abortion and preterm delivery associated with polypectomy during pregnancy is greater in patients with decidual polyps. It might be safer not to remove cervical polyps during pregnancy, except in cases in which the polyps are suspected to be malignant.
