Meta-Analysis Review
We conducted a meta-analysis of IOTA (international ovarian tumor analysis) ADNEX (Assessment of Different NEoplasias in the adneXa) as ultrasound system and MRI (magnetic resonance imaging) ADNEX scoring systems as MR system to assess their diagnostic test accuracy for differentiating benign from malignant adnexal masses of the ovary. We performed an electronic search for relevant publications in the English language up to February 2021 using PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Web of Science, and Google scholar databases and search engines. We computed the pooled sensitivity, pooled specificity, and summary receiver operating characteristics curve (SROC) using the statistical software STATA (Version 13, College Station, TX, StataCorp LP). Based on 11 studies using IOTA-ADNEX, we observed pooled sensitivity, specificity, area under curve, and diagnostic odds ratio were 96% (95% CI, 94% to 97%), 79% (95% CI, 70% to 86 %), 97% (95% CI, 95% to 98%), and 88 (95% CI, 43 to 180). Based on five studies using MR-ADNEX scoring system the pooled sensitivity, specificity, area under curve and diagnostic odds ratio were 91 % (95% CI, 87% to 94 %), 95% (95% CI, 92% to 97 %), 98% (95% CI, 96% to 99%), and 189 (95% CI, 90 to 396) respectively. Our meta-analysis results demonstrate that the MR-ADNEX scoring system had higher specificity however bit lower sensitivity compared to the IOTA-ADNEX scoring system for discriminating benign from malignant ovarian tumors.

Meta-Analysis Review
INTRODUCTION
Many national guidelines concerning the management of ovarian cancer currently advocate the risk of malignancy index (RMI) to characterise ovarian pathology. However, other methods, such as subjective assessment, International Ovarian Tumour Analysis (IOTA) simple ultrasound-based rules (simple rules) and IOTA logistic regression model 2 (LR2) seem to be superior to the RMI. Our objective was to compare the diagnostic accuracy of subjective assessment, simple rules, LR2 and RMI for differentiating benign from malignant adnexal masses prior to surgery.
MATERIALS AND METHODS
MEDLINE, EMBASE and CENTRAL were searched (January 1990-August 2015). Eligibility criteria were prospective diagnostic studies designed to preoperatively predict ovarian cancer in women with an adnexal mass.
RESULTS
We analysed 47 articles, enrolling 19,674 adnexal tumours; 13,953 (70.9%) benign and 5721 (29.1%) malignant. Subjective assessment by experts performed best with a pooled sensitivity of 0.93 (95% confidence interval [CI] 0.92-0.95) and specificity of 0.89 (95% CI 0.86-0.92). Simple rules (classifying inconclusives as malignant) (sensitivity 0.93 [95% CI 0.91-0.95] and specificity 0.80 [95% CI 0.77-0.82]) and LR2 (sensitivity 0.93 [95% CI 0.89-0.95] and specificity 0.84 [95% CI 0.78-0.89]) outperformed RMI (sensitivity 0.75 [95% CI 0.72-0.79], specificity 0.92 [95% CI 0.88-0.94]). A two-step strategy using simple rules, when inconclusive added by subjective assessment, matched test performance of subjective assessment by expert examiners (sensitivity 0.91 [95% CI 0.89-0.93] and specificity 0.91 [95% CI 0.87-0.94]).
CONCLUSIONS
A two-step strategy of simple rules with subjective assessment for inconclusive tumours yielded best results and matched test performance of expert ultrasound examiners. The LR2 model can be used as an alternative if an expert is not available.

Review
BACKGROUND
Pelvic masses are a common gynecologic problem, and majority of them are diagnosed as ovarian tumors finally. Sometimes, it is hard to distinguish the origin of these pelvic masses. The following case is a solitary neurofibroma arising from the right-side obturator nerve, which was impressed as a right-side ovarian tumor initially. We reported this case, and also performed a PRISMA-driven systematic review to summary the similar cases in the literature. This review includes image, molecular and pathological findings and outcome of neurofibroma.
CASE PRESENTATION
A 33-year-old woman with a regular menstrual period denied any symptoms or signs. During her physical check-up, image examination revealed a right-side heterogeneous pelvic mass; it was suggestive of a complex of right-side ovarian tumor. A provisional diagnosis of retroperitoneal pelvic mass, probably a benign ovarian tumor, was made. Excision of the right-side pelvic mass was performed. We sent the specimens for frozen pathology, which indicated neurofibroma and lipomatous tumor and that the possibility of liposarcoma cannot be excluded. A segment of the obturator nerve was attached to the tumor and was severed. A right-side obturator nerve tear during tumor excision was observed, and a neurosurgeon was consulted for obturator nerve grafting and repair. The patient complained of mild weakness and paresthesia affecting the right leg, and we consulted a rehabilitation doctor for neuron injury. The patient's recovery was uneventful, and she was discharged eight days after the drain was removed. Further rehabilitation treatment was arranged.
CONCLUSION
A neurofibroma is an uncommon pelvic retroperitoneal tumor, and it can be misdiagnosed as an adnexal mass. To our knowledge, this is a rare case of a solitary neurofibroma arising from the obturator nerve. It usually does not have any neurological deficit. We present this case to demonstrate that pelvic neurofibroma can be mistaken for an adnexal mass. This fact should be borne in mind during the diagnosis process.

Meta-Analysis
BACKGROUND
Ileal-pouch anal anastomosis is used for treatment of different conditions, including mucosal ulcerative colitis and familial adenomatous polyposis. The present systematic review aimed to assess the literature for studies that compared the outcome of ileal-pouch anal anastomosis in patients with obesity versus patients with ideal weight.
METHODS
A systematic literature search of electronic databases including PubMed, Scopus, Web of Science, and Cochrane library was performed and reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The main outcome measures were pouch failure, pouch complications, overall complications, operation time, blood loss, and hospital stay.
RESULTS
This systematic review included 6 retrospective studies (3,460 patients). Out of the total number of patients, 19.8% had obesity or overweight. Patients with obesity were significantly less likely to have laparoscopic ileal-pouch anal anastomosis compared with patients with ideal body mass index (odds ratio = 0.436; P = .017). The weighted mean operation time and blood loss were significantly longer in the obesity group than the ideal weight group (weighted mean difference = 22.84; P = .006) and (weighted mean difference = 85.8; P < .001). The obesity group was associated with significantly higher odds of total complications (odds ratio = 2.27; P < .001), leak (odds ratio = 1.81; P = .036), and incisional hernia (odds ratio = 4.56; P < .001). The 2 groups had comparable rates of pouch failure, pouchitis, stricture, pelvic sepsis, wound infection, bowel obstruction, ileus, and venous thromboembolism. Male sex, longer operation time, and including inflammatory bowel disease patients only were significantly associated with higher complications in the obesity group.
CONCLUSION
Patients with obesity who undergo ileal-pouch anal anastomosis are more likely to have laparotomy rather than a laparoscopic procedure, have longer operation time, greater blood loss, higher overall complications, leak and incisional hernia, and longer hospital stay.

IMPORTANCE
The 2014 US Preventive Services Task Force (USPSTF) recommendation statement supported the effectiveness of screening for chlamydia and gonorrhea in asymptomatic, sexually active women 24 years or younger and in older women at increased risk for infection, although evidence for screening in men was insufficient.
OBJECTIVE
To update the 2014 USPSTF review on screening for chlamydial and gonococcal infection in adults and adolescents, including those who are pregnant.
DATA SOURCES
Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Ovid MEDLINE (January 1, 2014, through May 28, 2020) with surveillance through May 21, 2021.
STUDY SELECTION
Randomized clinical trials and observational studies of screening effectiveness, accuracy of risk stratification and alternative screening methods, accuracy of tests, and screening harms.
DATA EXTRACTION AND SYNTHESIS
One investigator abstracted data; a second checked accuracy. Two investigators independently assessed study quality.
MAIN OUTCOMES AND MEASURES
Complications of infection; infection transmission or acquisition; diagnostic accuracy of anatomical site-specific testing and collection methods; screening harms.
RESULTS
Twenty-seven studies were included (N = 179 515). Chlamydia screening compared with no screening was significantly associated with reduced risk of pelvic inflammatory disease (PID) in 2 of 4 trials and with reduced hospital-diagnosed PID (0.24% vs 0.38%); relative risk, 0.6 [95% CI, 0.4-1.0]), but not clinic-diagnosed PID or epididymitis, in the largest trial. In studies of risk prediction instruments in asymptomatic women, age younger than 22 years demonstrated comparable accuracy to extensive criteria. Sensitivity of chlamydial testing was similar at endocervical (89%-100%) and self- and clinician-collected vaginal (90%-100%) sites for women and at meatal (100%), urethral (99%), and rectal (92%) sites for men but lower at pharyngeal sites (69.2%) for men who have sex with men. Sensitivity of gonococcal testing was 89% or greater for all anatomical samples. False-positive and false-negative testing rates were low across anatomical sites and collection methods.
CONCLUSIONS AND RELEVANCE
Screening for chlamydial infection was significantly associated with a lower risk of PID in young women. Risk prediction criteria demonstrated limited accuracy beyond age. Testing for asymptomatic chlamydial and gonococcal infections was highly accurate at most anatomical sites, including urine and self-collected specimens. Effectiveness of screening in men and during pregnancy, optimal screening intervals, and adverse effects of screening require further evaluation.

Meta-Analysis
OBJECTIVE
To quantify the absolute risks of adverse fetal outcomes and maternal mortality following nonobstetric abdominopelvic surgery in pregnancy.
SUMMARY BACKGROUND DATA
Surgery is often necessary in pregnancy, but absolute measures of risk required to guide perioperative management are lacking.
METHODS
We systematically searched MEDLINE, EMBASE, and EvidenceBased Medicine Reviews from January 1, 2000, to December 9, 2020, for observational studies and randomized trials of pregnant patients undergoing nonobstetric abdominopelvic surgery. We determined the pooled proportions of fetal loss, preterm birth, and maternal mortality using a generalized linear random/mixed effects model with a logit link.
RESULTS
We identified 114 observational studies (52 [46%] appendectomy, 34 [30%] adnexal, 8 [7%] cholecystectomy, 20 [17%] mixed types) reporting on 67,111 pregnant patients. Overall pooled proportions of fetal loss, preterm birth, and maternal mortality were 2.8% (95% CI 2.2-3.6), 9.7% (95% CI 8.3-11.4), and 0.04% (95% CI 0.02-0.09; 4/10,000), respectively. Rates of fetal loss and preterm birth were higher for pelvic inflammatory conditions (eg, appendectomy, adnexal torsion) than for abdominal or nonurgent conditions (eg, cholecystectomy, adnexal mass). Surgery in the second and third trimesters was associated with lower rates of fetal loss (0.1%) and higher rates of preterm birth (13.5%) than surgery in the first and second trimesters (fetal loss 2.9%, preterm birth 5.6%).
CONCLUSIONS
Absolute risks of adverse fetal outcomes after nonobstetric abdom- inopelvic surgery vary with gestational age, indication, and acuity. Pooled estimates derived here identify high-risk clinical scenarios, and can inform implementation of mitigation strategies and improve preoperative counselling.

Ultrasound in Obstetrics & Gynecology :... Jan 2016To determine the accuracy of ultrasound in the diagnosis of a tubal ectopic pregnancy in the absence of an obvious extrauterine embryo. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
To determine the accuracy of ultrasound in the diagnosis of a tubal ectopic pregnancy in the absence of an obvious extrauterine embryo.
METHODS
This was a systematic review conducted in accordance with the PRISMA statement and registered with PROSPERO. We searched MEDLINE, EMBASE and The Cochrane Library for relevant citations from database inception to July 2014. Studies were selected in a two-stage process and their data extracted by two reviewers. Accuracy measures were calculated for each ultrasound sign, i.e. empty uterus, pseudosac, adnexal mass and free fluid in the pouch of Douglas, alone and in various combinations. Individual study estimates were plotted in summary receiver-operating characteristics curves and forest plots for examination of heterogeneity. The quality of included studies was assessed.
RESULTS
Thirty-one studies including 5858 women were selected from 19,959 citations. Following meta-analysis, an empty uterus on ultrasound was found to predict an ectopic pregnancy with a sensitivity of 81.1% (95% CI, 42.1-96.2%) and specificity of 79.5% (95% CI, 68.9-87.1%). The corresponding performance of the pseudosac, adnexal mass and free fluid were: 5.5% (95% CI, 3.3-9.0%) and 94.2% (95% CI, 75.9-98.8%); 63.5% (95% CI, 48.5-76.3%) and 91.4% (95% CI, 83.6-95.7%); and 47.2% (95% CI, 33.2-61.7%) and 92.3% (95% CI, 85.6-96.0%), respectively.
CONCLUSION
Visualization of an empty uterus, adnexal mass, free fluid or a pseudosac has poor sensitivity for the diagnosis of a tubal pregnancy when an obvious extrauterine embryo is absent, but it has good specificity. We can therefore infer that ultrasound is more useful for 'ruling in' a tubal pregnancy than 'ruling out' one. However, the findings were limited by the poor quality of some included studies and heterogeneity in the index test and reference standard.

Meta-Analysis
INTRODUCTION
Pregnant women with a body mass index (BMI) ≥40 kg/m are at an increased risk of requiring planned- and unplanned cesarean deliveries (CD). The aim of this systematic review is to compare outcomes in women with BMI ≥ 40 kg/m based on planned and actual mode of birth.
MATERIAL AND METHODS
Five databases were searched for English and French-language publications until February 2019, and all studies reporting on delivery outcomes in women with BMI ≥ 40 kg/m , stratified by planned and actual mode of birth, were included. Risk-of-bias was assessed using the Newcastle-Ottawa Scale. Relative risks (RR) and 95% confidence intervals were calculated using random-effects meta-analysis.
RESULTS
Ten observational studies were included. Anticipated vaginal birth vs planned CD (5 studies, n = 2216) was associated with higher risk for postpartum hemorrhage (13.0% vs 4.1%, P < .001, numbers needed to harm (NNH = 11), I = 0%) but lower risk for wound complications (7.6% vs 14.5%, P < .001, numbers needed to treat (NNT = 15), I = 58.3%). Planned trial of labor vs repeat CD (3 studies, n = 4144) was associated with higher risk for uterine dehiscence (0.94% vs 0.42%, P = .04, NNH = 200, I = 0%), endometritis (5.1% vs 2.2%, P < .001, NNH = 35, I = 0%), prolonged hospitalization (one study, 30.3% vs 26.0%, P = .003, NNH = 23), low five-minute Apgar scores (4.9% vs 1.7%, RR 2.95 (2.03, 4.28), NNH = 30, I = 0%) and birth trauma (1.1% vs 0.2%, P < .001, NNH = 111, I = 0%). Successful vaginal birth vs intrapartum CD (n = 3625) was associated with lower risk of postpartum hemorrhage (15.1% vs 70%, P < .001, NNT = 2, I = 0%), wound complications (one study, 0% vs 4.4%, P = .007, NNT = 23), prolonged hospitalization (one study, 1.9% vs 6.7%, 0.04, NNT = 21) and low five-minute Apgar scores (one study, 1.0% vs 5.6%, P = .03, NNT = 22), but more birth trauma (5.9% vs 0.6%, P = .005, NNH = 19, I = 0%). Compared groups had dissimilar demographic characteristics. Although studies scored 6-7/9 on risk-of-bias assessment, they were at high-risk for confounding by indication.
CONCLUSIONS
Evidence from observational studies suggests clinical equipoise regarding the optimal mode of delivery in women with BMI ≥ 40 kg/m and no prior CD. This question is best answered by a randomized trial. Based on an unplanned subgroup analysis, for women with BMI ≥ 40 kg/m and prior CD, repeat CD may be associated with better clinical outcomes.

Review
To identify clinical presentations, main causes, and prognosis of ophthalmic involvement in chronic lymphocytic leukemia (CLL), we performed a systematic review of articles describing CLL ophthalmic involvement in January 2019, using the PubMed database. We found 86 articles describing 123 cases of patients with ophthalmic involvement associated with CLL. Ophthalmic symptoms were CLL's first manifestation in 25.6% of patients and revealed Richter transformation in 11.0%. There were three main causes of ophthalmic features: CLL-infiltration (52.0%), lymphoma (26.0%), and infection (15.4%), with specific clinical and radiological characteristics. CLL-infiltration was mostly bilateral, whereas lymphoma was usually unilateral (P = 0.02). Optic neuropathy was always secondary to CLL-infiltration, and in those cases, cerebrospinal fluid immunophenotyping was a potential alternative to invasive biopsy as it confirmed the diagnosis in 4 patients (36.4%). On the contrary, lymphoma usually presented as adnexal involvement (P = 0.04), particularly as an orbital mass (P = 0.004). Infections concerned mostly patients previously treated for CLL (P < 0.0001), and main presentations included posterior uveitis (P = 0.0002) and retinal infiltrates (P < 0.0001). Overall, the prognosis was poor, as 29.3% of the patients died within 36 months of follow-up, and 26.1% had a partial or total visual loss. Eye infections were associated with the poorest prognosis as 47% of patients died, with a 6-month-median survival.

Meta-Analysis
PURPOSE
To perform a systematic review and meta-analysis of studies comparing the diagnostic accuracy of Risk of Ovarian Malignancy Algorithm (ROMA) and risk of malignancy index (RMI) for detecting ovarian cancer.
METHODS
A systematic review and meta-analysis was performed according to PRISMA statement. A search for studies evaluating the diagnostic performance of ROMA and RMI-I indices for detecting ovarian malignancy from January 2010 to October 2018 was performed in the PubMed/MEDLINE and Web of Science databases. The quality of the studies was evaluated by the Quality Assessment of Diagnostic Accuracy Studies 2.
RESULTS
Sixty-six citations were identified. After exclusions, 8 papers comprising 2,662 women (1,319 premenopausal and 1,343 postmenopausal) were ultimately included. The mean prevalence of ovarian malignancy was 29.0% in premenopausal women and 51.0% in postmenopausal women. High risk of bias for patient selection was observed for most studies. ROMA and RMI-I had a similar diagnostic performance in postmenopausal women (pooled sensitivity [87 vs. 77%] and specificity [75 vs. 85%], respectively. p = 0.29). In premenopausal women, RMI-I showed better specificity than ROMA (89 vs. 78%, p = 0.022) with similar sensitivity (73 vs. 80%, p= 0.27). Significant heterogeneity was found for sensitivity and specificity in comparisons of both groups.
CONCLUSIONS
ROMA and RMI-I have similar diagnostic performance for detecting ovarian cancer in women presenting with an adnexal mass. However, RMI-I showed a higher specificity than ROMA in premenopausal women. Notwithstanding, as the risk of bias is high in most studies, our results should be interpreted with caution.
