Background: Preterm labour and delivery cause major health burden to the society due to high perinatal morbidities and mortality and long-term health implications and also affects maternal. An effective and objective way for predicting preterm delivery is measurement of cervical length by transvaginal sonography as it allows better quality and accurate visualization of uterine cervix. Cervical length (<25 mm) is good and accurate cervical biometry for prediction of preterm birth. The objective of this study was to measure cervical length by transvaginal sonography for predicting preterm labour and fetal outcome.Methods: This prospective observational study was conducted in department of obstetrics and gynaecology, at SVPIMSR hospital, Ahmedabad from July 2018 to December 2019 in 150 antenatal women to assess cervical changes (cervical length, dilatation of internal OS, funnelling etc.) between 16 to 24 weeks of gestation and these cases followed till delivery and results were analysed.Results:150 antenatal women who fulfilled the selection criteria were studied using transvaginal ultrasound between 16-24 weeks of gestation, out of them 36 (24%) women delivered preterm babies. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) recorded in this study were 80.5%, 94.73%, 82.85% and 93.91% respectively.Conclusion: Transvaginal sonography is the most useful and better, safe, accurate, most effective, less expensive, objective and acceptable technique for assessing cervical length in all antenatal women and predicting the preterm labour when assessed between 16 -24 weeks of gestational age.

Background: Preterm labour and delivery contributes significantly to perinatal morbidity and mortality in twin gestation. Measurement of cervical length during antenatal period and subsequent follow up may identify women at risk for preterm labour.  The purpose of this study was to determine if measurement of cervical length at 22 to 26 weeks can be used as a predictor of preterm labour in twin pregnancy.Methods: This prospective observational study was carried out in 50 women with twin gestation in a tertiary care teaching hospital. Cervical length was measured using transvaginal sonography and repeated every four weeks till delivery. Cervical length of ≤30 mm was taken as short cervix and delivery before 37 weeks was taken as preterm delivery.Results: Total of 18 out of 50 women (36%) delivered between 32 to 34 weeks, 14 out of 50 (28%) delivered between 34 to 37 weeks, 7 out of 50 (14%) delivered at less than 32 weeks. Therefore, total preterm deliveries at less than 37 weeks were 78%. Total 11 out of 50 (22%) delivered at term i.e. at more than 37weeks. In women, who had short cervical length (≤ 30 mm) at the time of presentation, 14 out of 37 (38 %) delivered between 30 to 34 weeks, 12 out of 37 (32 %) women delivered between 34 to 37 weeks, 5 out of 37 (14%) delivered at ≤ 30 weeks. Rest 6 out of 37 (16 %) delivered after 37 weeks.Conclusions: Short cervical length of ≤30 mm on transvaginal sonography at 22-26 weeks of gestation in twin pregnancy may be used as a screening tool in prediction of preterm labour in asymptomatic twin pregnancy.

Transvagival sonography is superior to transabdominal sonography in most cases of pelvic pathology. Objective of this study is to evaluate the clinical usefulness of transvaginal ultrasonography (TVS) in pre, peri and post menopausal women suspected to have endometrial carcinoma. This cross sectional study was done with 40 patients who are clinically suspected having thickened endometrium. The study was carried out January 2007 to November 2008 for a period of two years. The patients having endometrial carcinoma diagnosed by TVS was correlated with histopathological diagnosis following collection of the report from the respective cases. Of total 40 cases, 2(5.0%) cases were endometrial carcinoma and 38(95.0%) were negative for endometrial carcinoma respectively in TVS findings. On the other hand 3(7.5%) cases were endometrial carcinoma and 37 (92.5%) cases were negative for endometrial carcinoma in histopathological findings. The validity of TVS in diagnosis of endometrial carcinoma were studied by calculating sensitivity, specificity, accuracy, positive predictive value and negative predictive value, which were 67 percent, 100 percent, 98 percent, 100 percent and 97 percent respectively. As the TVS findings of the present study correlated well with the histopathology findings and the validity test values were higher than observed by others, it can be concluded that TVS is sensitive and accurate modality in the evaluation of endometrial carcinoma.

Abstract Introduction Thrombospondin 1, desmoplakin and stratifin are putative biomarkers for the prediction of preterm birth. This study aimed to validate the predictive capability of these biomarkers in patients at risk of preterm birth. Materials and Methods We included 109 women with symptoms of threatened spontaneous preterm birth between weeks 20 0/7 and 31 6/7 of gestation. Inclusion criteria were uterine contractions, cervical length of less than 25 mm, or a personal history of spontaneous preterm birth. Multiple gestations were also included. Samples of cervicovaginal fluid were taken before performing a digital examination and transvaginal ultrasound. Levels of cervicovaginal thrombospondin 1, desmoplakin and stratifin were quantified by enzyme-linked immunosorbent assays. The primary endpoint was spontaneous preterm birth before 34 + 0 weeks of gestation. Results Sixteen women (14.7%) delivered before 34 + 0 weeks. Median levels of thrombospondin 1 were higher in samples where birth occurred before 34 weeks vs. ≥ 34 weeks of gestation (4904 vs. 469 pg/mL, p < 0.001). Receiver operator characteristics analysis resulted in an area under the curve of 0.86 (p < 0.0001). At an optimal cut-off value of 2163 pg/mL, sensitivity, specificity, positive predictive value and negative predictive value were 0.94, 0.77, 0.42 and 0.99, respectively, with an adjusted odds ratio of 32.9 (95% CI: 3.1 – 345, p = 0.004). Multiple gestation, cervical length, and preterm labor had no impact on the results. Survival analysis revealed a predictive period of more than eight weeks. Levels of desmoplakin and stratifin did not differ between groups. Conclusion Thrombospondin 1 allowed long-term risk estimation of spontaneous preterm birth.

Aims: This study aims to find out the role of colposcopy and its correlation with cervical biopsy in detection of pre malignant cervical lesion. Methodology: This is hospital based prospective observational study on 60 cases with abnormal cervical cytology reports conducted in the Department of Obstetrics and Gynecology, PMWH, Thapathali, Kathmandu. Colposcopy guided biopsies were done and findings noted. Results: Among 60 cases enrolled in the study the most common cervical cytology finding was ASCUS, LSIL, HSIL and ASC-H present in 46.6%, 31.6%, 15% and 6.6% respectively.  The colposcopy finding among these cases was normal, CIN1, CIN 2 and CIN 3 in 45%, 23.3%, 16.7% and 9% respectively. Among these cases the most common biopsy finding was normal, CIN 1, CIN 2, CIN 3 and squamous cell carcinoma in 55%, 18.3%, 8.3%, 15% and 3.3% respectively. The sensitivity, specificity, positive predictive value and negative predictive value of colposcopy with CIN 1 as disease threshold was calculated to be 80.6%, 93.1%, 81.8% and 92.6% respectively. While evaluating the validity of colposcopy with histopathology, colposcopy seems to make an accurate diagnosis in 75% of cases, overestimating in 15% and underestimating in 8% of cases. Conclusions: There is a good correlation of colposcopy with histopathological diagnosis of cervical cancer. Keywords: colposcopy, cytology, diagnosis, premalignant

Background: This prospective observational study was conducted to evaluate the anterior cervical angle (ACA) of the uterus by transvaginal sonography (TVS) and to determine the feasibility to predict spontaneous preterm birth (PTB). The duration of the study was from December 2014-December 2016.The participants included 100 pregnant women with singleton pregnancy who were asymptomatic. They were enrolled after excluding all known risk factors of preterm birth.Methods: The ACA and cervical length were measured in all cases by transvaginal sonography either in the 1st trimester or 2nd trimester. All cases were followed and well documented with respect to the gestational age at delivery.Results: There was a significant risk of preterm labour in women with cervical length <2.5cm in the 2nd trimester with Odds Ratio 3.625, P value=0.001, sensitivity 75% and specificity 79.31%. The positive predictive value was 33.33% and negative predictive value 95.83%. The false positive rate was 20.65% and false negative rate 25%. The difference of mean cervical angle in women who delivered preterm and that of those who delivered at term, in the 1st    trimester (preterm group 114.2°Vs term group 93.0°, P<0.001) and in the 2nd trimester (preterm group 127.66° Vs term group 103.65°, P <0.001) was significant. An ACA of 114.2° in the 1st trimester was associated with a risk of spontaneous preterm birth (P value 0.0065, sensitivity 90% and specificity 80%). An ACA of 127.66° in 2nd trimester was associated with a risk of spontaneous preterm birth (P value 0.0004, sensitivity 80%and specificity 88.23%).Conclusions: Despite the limitations of a small sample size, the results suggest that the anterior cervical angle has potential as a new predictor of spontaneous preterm birth especially when measured in the 1st trimester.

BackgroundThe aim of the study was to compare the accuracy of hydrosonography with that of transvaginal ultrasonography in detection of intracavitary pathologies in patients with history of abnormal uterine bleeding.Study designProspective, randomized, and unblinded study.Material and methodsA total of 197 women (n = 130 premenopausal and n = 67 postmenopausal) aged between 23 and 71 years (mean age 45.7 ± 8.9) presenting with a history of abnormal uterine bleeding were included into the study. Hydrosonography was carried out by experienced gynecologists, on the same setting in an outpatient clinic immediately after the performance of transvaginal sonography. The finally obtained surgical-pathologic findings were compared with the results obtained from transvaginal sonography and hydrosonography. Sensitivity, specificity, positive, and negative predictive values were calculated for each procedure.ResultsThe surgical-pathologic examination confirmed normal physiologic endometrium in 50 (48%) of 104 women who were said to have normal endometrium on transvaginal sonography. Seventy (75%) of 93 women diagnosed of intracavitary pathologies on transvaginal sonography were confirmed by surgical-pathologic findings. The sensitivity, specificity, positive predictive value, and negative predictive value of transvaginal sonography in the detection of intracavitary pathology were 56, 68, 75, and 48%, respectively. Surgical-pathologic results revealed intracavitary pathologies in 23 (30%) of 76 women who were said to have normal endometrium on hydrosonography. Among 121 women diagnosed of intracavitary pathologies on hydrosonography, 101 (81%) women were confirmed after histological evaluation of the surgical specimens. The sensitivity, specificity, positive predictive value, and negative predictive value of hydrosonography in the detection of intracavitary pathology were 81, 73, 83, and 70%, respectively. Sensitivity and negative predictive value were significantly higher with hydrosonography. There were five cases of endometrial malignancy in which one of the case of malignancy was on polyp and two cases of endometrial hyperplasia with atypia which were not stated on sonographic results.ConclusionHydrosonography is more accurate than transvaginal ultrasography in the detection of intracavitary pathologies in women with abnormal uterine bleeding.

Background: The aim of the study was to find out pre-induction cervical length by TV Sonography, determine Bishops score and to co-relate the obstetric outcome with these two variables.Methods: A study was done on 100 women with singleton pregnancies at 37-42 weeks of gestation, admitted for induction of labour in the Department of Obstetrics and Gynaecology at SGRDIMSR, Vallah, Amritsar, Punjab, India. All women underwent cervical assessment by both transvaginal ultrasound and Bishop Score and the outcome of labour induction was determined.Results: Of the 100 women, 53 women had vaginal delivery and 47 landed into LSCS. Bishop score < 6 and cervical length > 3 cm are cut off values of cervical unfavourablity. Successful induction was achieved among 87.5% and 78% women with favorable cervix according to Bishop Score and Cervical length respectively .Among the 92 and 50 women with unfavourable cervix according to Bishop score and cervical length, 48 (52.17%) and 14 (28%) had vaginal delivery respectively.Conclusions: Hence, cervical length by transvaginal ultrasound is a better predictor for the success of induction of labour as compared with assessment by Bishop Score alone.
