Evaluation of HSG and SIS Diagnostic Value in Comparison to Hysteroscopy to Detect Intrauterine Abnormalities in Infertile Women in Iran

Objective: Hysteroscopy is the gold standard in evaluation of uterine cavity. However, being invasive and its possible adverse effects have reduced popularity of hysteroscopy and clinicians have always been looking for a valid alternative for hysteroscopy. In the current study, we aimed to compare diagnostic value of Saline induced Sonography with HSG in diagnosis of intrauterine abnormalities. Material and Method: We performed a retrospective study on 81 infertile women who underwent hysteroscopy, SIS, and HSG at Taleghani infertility center during their IVF treatment course. Polyp, fibroids, adhesion and septate uterus were considered as abnormality. We reported agreement percent, Kappa, sensitivity, specificity, Area Under Curve, Diagnostic Odds Ratio, Positive Predictive Value, and Negative Predictive value for both SIS and HSG. Results: Total agreement between SIS and hysteroscopy was 85.1, while it was 23.4 for HSG. We also observed considerably higher Kappa for SIS (80.1%) than HSG (15.5%). Overall sensitivity and specificity of SIS for diagnosis of all type of anomaly including both uterine abnormalities and Acquired uterine pathologies was 90.1% (95% CI= 80.7, 95.9) and 90.0% (95% CI= 55.5, 99.7). Meanwhile overall sensitivity and specificity of Hysterosalpingography where hysteroscopy was considered as the gold standard was 54.9 (42.7, 66.8) and 50.0 (18.7, 81.3). Conclusion: SIS is more sensitive tools than HSG for diagnosis of intrauterine abnormalities and could be considered one of the best alternative of hysteroscopy. It provides more accurate detail diagnostic information with high sensitivity and specificity.

ObjectiveThe aim of this study was to evaluate the diagnostic accuracy of hysteroscopic chromopertubation (HCT) in the assessment of tubal patency by comparing its results with laparoscopic chromopertubation (LCT).Study DesignThe population of this prospective cohort study consisted of both fertile and infertile women. Sixty-four women were included to the study. HCT was assessed by the observation of the transport of highly concentrated methylene blue from uterine cavity to tubal ostia. The results of HCT were compared with the results of LCT as a gold standard. The accuracy of HCT, sensitivity, specificity, positive and negative predictive values in diagnosing tubal patency were calculated.ResultsThe results of HCT and LCT were evaluated for right and left tubes, separately. One hundred and twenty-eight tubes were determined. Sensitivity, specificity, positive and negative predictive values for HCT were; 85.85%, 59.09%, 91% and 46.43%, respectively.Conclusion This study’s result showed that HCT had high sensitivity and moderate specificity values in the assessment of tubal patency. HCT during office hysteroscopy could give the chance to practitioners to assess tubal patency without subjecting the patient to multiple procedures.

ABSTRACT Introduction Two of the most frequent procedures performed on infertile women are two-dimensional ultrasound (2DUS) and three-dimensional ultrasound (3DUS). Hysteroscopy is considered as the gold standard for evaluation of acquired endometrial lesions in infertile women; however, 3DUS is used as a noninvasive, less expensive, and reliable assessment method for evaluation of the intrauterine lesions in infertile women. We aimed to compare the diagnostic efficiency between 3DUS and hysteroscopy in the detection of lesions (polyps, submucous leiomyoma, and synechiae) in infertile women. Materials and methods In this prospective observational study, infertile women (n = 155) with indication of hysteroscopy were scheduled to undergo 3DUS prior to hysteroscopy from September 2010 to 2011. Women with suspected congenital uterine anomalies were excluded. The sensitivity and specificity values of 3DUS were compared with those of hysteroscopy. Hysteroscopy was used as the gold standard for diagnosis of intrauterine lesions in infertile women. Results Of the 155 women, 50 were found to have an intracavitary abnormality, 36 had polyps, 12 had myomas, and 7 had synechiae on hysteroscopic findings. Examination with 3DUS in the diagnosis of intrauterine lesions reached an accuracy of 94%, and 92.15 and 96.9% of sensitivity and specificity respectively. Positive predictive value (PPV) was 83.9%, and a negative predictive value (NPV) was 91.3% (LR+ = 10.75, LR+ = 0.065). Conclusion According to our results, 3DUS has a reliable diagnostic accuracy for intrauterine lesions, and it may limit unnecessary hysteroscopy in patients with normal results.

Background: Even though there are many programs run by Government to tackle the problem of malnutrition in India, problem of malnutrition is still there. Malnutrition leads to infections and even can lead to death of child in severe cases. The mortality rate is very high compared to other countries. The objective of the study to study validity of age independent various nutritional status indices in comparison to gold standard of weight for ageMethods: Present study was institution based cross sectional study carried out at SDA high school, from January 2019 to July 2019 among 58 school children aged 34-92 months of age. Anthropometric measurements like weight, height, head circumference, chest circumference, mid arm circumference were recorded as per the standard guidelines. Weight for height, weight of age, Kanawati Index, Jeliffe’s ratio, Rao index, and Dugdales index was calculated. Gold standard used was weight for age. Sensitivity, specificity, positive predictive value and negative predictive value were calculated for these indices.Results: Majority of the children belonged to 48-60 months and 61-72 months i.e. 29.3% each. Males were more than females. Prevalence of malnutrition was 60.3%, 48.3%, 51.7%, 91.4%, and 56.8% based on weight for age, Kanawati index, Rao index, Jeliffe’s ratio and Dugdale’s index respectively. Dugdale’s index was found to have high sensitivity (85.7%) and specificity (86.9%) compared to all other indices.Conclusions: Among age independent indices of nutritional status available, Dugdales index can be used as it has been found that it has remarkably higher sensitivity and specificity compared to other age independent indices of nutritional status.

Introduction. Leptospirosis is an acute febrile illness, known for its protean clinical manifestations and the challenge in differentiating from other infectious diseases. Standardized confirmatory test is antibody dependent and not accessible by the suburban community. This study measures efficiency of an immune-chromatographic assay, Leptocheck WB, in detecting acute leptospirosis. Methods. A total of 142 sera were used for kit evaluation. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated by comparing rapid kit results with gold standard laboratory, microscopic agglutination test (MAT). Results. We found this rapid kit to have a sensitivity and specificity of 66.6% and 78.9%, respectively, whereas the PPV and NPV of the kit appeared to be 73.3% and 73.2%, respectively. Discussion. Test efficiency of this rapid kit is reasonable. It is specific in detecting leptospiral antibody and assures clinician of accurate diagnosis by having higher PPV and NPV. It is prompt and efficient in comparison with conventional methods in assisting differential diagnosis. High sensitivity and specificity leptospirosis rapid test is indeed a crucial measure to assist the diagnosis of acute undifferentiated febrile illnesses.

Although the arcus corneae (AC) has long been used as an age indicator for forensic purposes, its diagnostic value has not been evaluated. To evaluate the AC as a predictor of chronological age, the author has studied the correlation of AC with respect to age of the deceased. A cross-sectional study was conducted of 342 Thai corpses at the Maharat Nakhon Ratchasima Hospital, Thailand. AC was graded into three levels: no AC, incomplete ring, and complete ring. One-way analysis of variance, chi-square test, binomial logistic regression, sensitivity, specificity, predictive values, and likelihood ratios were used for analysis. The Cohen’s kappa was used to determine the intraobserver and interobserver reliability. The prevalence of AC and the probability of complete AC were significant higher in corpses aged 60 years and above than in those under 60 years. Consequently, this study confirmed that the prevalence of AC was significantly correlated with the age of Thai individuals. If the complete AC is used as an indicator of age of 60 years and above, complete AC has high sensitivity (92.56%) but low specificity (72.85%), low positive predictive value (65.12%), but high negative predictive value (94.71%). For diagnostic value, the presence of AC can be used for age screening but not for absolute confirmation. The absence of AC indicates young age, incomplete AC indicates middle age, and complete AC indicates old age. The high intraobserver and interobserver reliability provides assurance of the value of AC as a means to estimate personal age.

Background: Uterine cavity abnormalities are seen as a cause of infertility in around 10%-15% and can go up to 50% in women with recurrent implantation failure. Saline infusion sonohysterography (SIS) is a minimally invasive diagnostic modality in the evaluation but hysteroscopy remains the gold standard in the assessment of intra uterine cavity. The aim of this study was to compare the diagnostic accuracy of saline infusion sonography (SIS) considering hysteroscopy (HS) as the gold standard to evaluate uterine cavity pathologies in infertile women at CHRACERH.Methods: Authors carried out a cross-sectional, retrospective study, over 2 years, from the 1st January 2016 to the 31st December 2017, with retrospective data collection in 110 records of infertile patients subjected to an ultrasound assessment of uterine cavity using saline as the contrast medium with a 6.5-MHz transvaginal transducer. When SIS found intra uterine abnormality, HS was done on a later date, using a 5 mm Bettocchi hysteroscope. Sensitivity, specificity, accuracy, positive and negative predictive values of SIS and HS were compared using the SPSS 20 software.Results: The mean age and body mass index were respectively 39.3±7.8 years and 28.7±4.1 kg/m². The main findings both in SIS and Hysteroscopy were respectively polyps (n=61; 55.5% vs 52.7%; n=58), myomas (n=43; 39.1% vs 31.8%; n=35), intrauterine adhesions (n=18; 16.4% vs 21.8%; n=24). The overall sensitivity, specificity and accuracy of SIS were 81.2%, 86.9% and 86.5% respectively.Conclusions: SIS as a diagnostic tool in the evaluation of intrauterine lesions has a good accuracy and can therefore replace HS when this later is not available, especially in our African setting.

Abstract Objectives To systematically review studies on the diagnostic accuracy of spleen stiffness measurement (SSM) for the detection of clinical significant portal hypertension (CSPH), severe portal hypertension (SPH), esophageal varices (EV), and high-risk esophageal varices (HREV) in patients with chronic liver diseases (CLD). Methods Through a systematic search, we identified 32 studies reporting the accuracy of SSM for the diagnosis of portal hypertension (PH) and/or EV in adults with CLD. A bivariate random-effects model was performed to estimate pooled sensitivity, specificity, likelihood ratio, positive predictive value (PPV), negative predictive value (NPV), and diagnostic odds ratios (DOR). The clinical utility of SSM was evaluated by Fagan plot. Results A total of 32 studies assessing 3952 patients were included in this meta-analysis. The pooled sensitivities of SSM were 0.85 (95% confidence interval (CI), 0.69–0.93) for CSPH; 0.84 (95% CI, 0.75–0.90) for SPH; 0.90 (95% CI, 0.83–0.94) for any EV; and 0.87 (95% CI, 0.77–0.93) for HREV. The pooled specificities of SSM were 0.86 (95% CI, 0.74–0.93) for CSPH; 0.84 (95% CI, 0.72–0.91) for SPH; 0.73 (95% CI, 0.66–0.79) for EV; and 0.66 (95% CI, 0.53–0.77) for HREV. Summary PPV and NPV of SSM for detecting HREV were 0.54 (95% CI, 0.47–0.62) and 0.88 (95% CI, 0.81–0.95), respectively. Conclusions Our meta-analysis suggests that SSM could be used as a helpful surveillance tool in management of CLD patients and was quite useful for ruling out the presence of HREV thereby avoiding unnecessary endoscopy. Key Points • SSM could be used to rule out the presence of HREV in patients with CLD thereby avoiding unnecessary endoscopy. • SSM has significant diagnostic value for CSPH and SPH with high sensitivity and specificity in patients with CLD. • SSM could be used as a helpful surveillance tool for clinicians managing CLD patients.

ABSTRACT Context. Coronavirus infectious disease-19 (COVID-19) diagnostics require understanding of how predictive values depend on sensitivity, specificity, and especially, low prevalence. Clear expectations, high sensitivity and specificity, and manufacturer disclosure will facilitate excellence of tests. Objectives. To derive mathematical equations for designing and interpreting COVID-19 tests, assess Food and Drug Administration (FDA) Emergency Use Authorization and Health Canada minimum requirements, establish sensitivity and specificity tiers, and enhance clinical performance in low prevalence settings. Design. PubMed and other sources generated articles on COVID-19 testing and prevalence. EndNote X9.1 consolidated references. Mathematica and open access software helped prove equations, perform recursive calculations, graph multivariate relationships, and visualize patterns, including a new relationship, predictive value geometric mean-squared. Results. Derived equations were used to illustrate shortcomings of COVID-19 diagnostics in low prevalence. Visual logistics helped establish sensitivity/specificity tiers. FDA/Canada's 90% sensitivity, 95% specificity minimum requirements generate excessive false positives at low prevalence. False positives exceed true positives at <5.3% prevalence, or if sensitivity is improved to 100% and specificity to 98%, at <2% prevalence. Recursive testing improves predictive value. Three tiers emerged from these results. With 100% sensitivity, physicians can select desired predictive values, then input local prevalence, to determine suitable specificity. Conclusions. Understanding low prevalence impact will help healthcare providers meet COVID-19 needs for effective testing. Laypersons should receive clinical performance disclosure when submitting specimens. Home testing needs to meet the same high standards as other tests. In the long run, it will be more cost-effective to improve COVID-19 POC tests rather than repeat testing multiple times.
