Background: Ovarian cancer possesses a challenge to screening tests due to its anatomical location, poor natural history, lack of specific lesion, symptoms and signs and low prevalence. Authors shall be considering RMI 2 and RMI 4 (forms of RMI) and comparing them with histopathology report to derive the sensitivity, specificity and other parameters of these tests.Methods: A prospective   study was conducted from September 2016- September 2017 at Mazumdar Shaw Hospital, Narayana Hrudayalaya, Bangalore.73 patients met the inclusion criteria. RMI 2   and RMI4 were calculated for all the patients and these scores were compared to the final histopathology reports.Results: In present study of 73 patients RMI2 showed a sensitivity of 86.6%, specificity of 86.5 %, Positive predictive value of 81.25% and negative predictive value of 90.24 %. Whereas RMI4 showed a sensitivity of 86.6%, specificity of 86.5 %, Positive predictive value of 83.87 and negative predictive value of 90.48 %. These results are comparable to other studies conducted.  The risk of malignancy index 2 and 4 are also almost comparable with each other and so either can be used for determining the risk of malignancy in patients with adnexal masses. These results were derived in an Indian population across all age groups showing that authors can apply this low-cost method even in resource limited settings.Conclusions: Authors found that Risk of malignancy index is a simple and affordable method to determine the likelihood of a patient having adnexal mass to be malignant. This can thus help save the resources and make the services available at grass root level.

Background: Adnexal masses present a diagnostic and therapeutic dilemma across age-groups. This study aimed to evaluate the performance of cancer antigen-125 (CA-125) in distinguishing between benign and malignant adnexal masses.Methods: This was a prospective, observational, single tertiary-care center study, done in North India from January, 2011 till December, 2012. Serum CA-125 levels was obtained preoperatively in consecutive patients presenting with ultrasonography confirmed adnexal masses. The cut-off value between benign and malignant was taken as 35 IU/ml. Histopathological diagnosis was obtained in all patients.Results: A total of 126 patients presented with adnexal masses, of which 100 were enrolled (mean age: 37.5±14.4 years, range: 18-80 years). Most of the masses were benign 81% (malignant=19%). Dermoid cyst (25.9%) and endometriomas (21%) were the most common benign masses. Serous (21%) and mucinous cystadeno-carcinoma (15.8%) were the most common malignant masses, more often seen in elderly, married, parous and post-menopausal patients. Mean CA-125 levels were significantly higher in malignant masses (257.30 [105.68-408.92] versus 19.26 [16.53-22.00], p<0.001). Overall sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CA-125 for diagnosing malignant adnexal mass was 94.7%, 87.65%, 64.28%, 98.6%, and 88.91% respectively. The same was 100%, 85.1%, 54.5%, 100%, 87.3% in premenopausal and 85.7%, 100%, 100%, 93.3%, 95.2% in postmenopausal women respectively.Conclusion: Benign masses form the bulk of the adnexal masses in all age groups. CA-125 levels has high sensitivity and negative predictive value in premenopausal patients while as high specificity and positive predictive value in postmenopausal patients.

Abstract Context The positive predictive value of newborn screening for CAH in New Zealand is approximately 10%. The use of a second tier liquid chromatography tandem mass spectrometry bloodspot steroid profile test with birthweight or gestational age adjusted screening cut-offs may result in further screening improvements. Methods Three years of newborn screening data with additional second tier steroid metabolites was evaluated (n=167672 births). Data from babies with a negative screening test and confirmed CAH cases were compared. First and second-tier steroid measurements were correlated with both birthweight and with gestational age. Analysis of variance was used to determine birthweight and gestational age groups. Screening cut-offs were determined and applied retrospectively to model screening performance. Results First tier immunoassay data correlated better with gestational age than with birthweight but there was no difference with second tier steroid measurements. Four distinct birthweight and gestational age groups were established for 17-hydroxyprogesterone and a steroid ratio measurement. Application of 97.5 th percentile second tier birthweight or gestational age adjusted cut-offs would result in 10 positive tests over the period of the study with 8 true positive screens and 2 false positive tests. The positive predictive value of screening would be increased from 10.8% to 80%. Conclusions The use of either birthweight or gestational age adjusted cut-offs for second tier screening tests can significantly reduce the false positive rate of newborn screening for congenital adrenal hyperplasia in New Zealand without loss in screening sensitivity.

Background: Several biomarkers, such as C-reactive protein (CRP) and Procalcitonin have been used to indicate bacterial infection in sepsis. They have limited sensitivity and specificity with high cost, placing them practically out of reach for poor patients in developing countries like India. Hence the need to evaluate eosinophil count and neutrophil-lymphocyte count ratio (NLCR) as an indicator of sepsis considering their lower cost and easier accessibility. The present study was done to establish that eosinopenia and the neutrophil-lymphocyte count are simple and effective tools as prognostic biomarkers for sepsis.Methods: A prospective observational study consisting of 50 patients with SIRS and sepsis on admission were studied. Neutrophil and lymphocyte count for first 4 consecutive days and then on alternate days up to one week was done. Absolute eosinophil count for first 2 consecutive days and then on alternate days up to one week was done.Results: Eosinopenia was noted to have 79.3% sensitivity, 76.2% specificity, positive predictive value 82.2% and negative predictive value 95.4% in predicting diagnosis and prognosis of sepsis. Neutrophil-lymphocyte ratio was found to have 86.2% sensitivity, 85.7% specificity, positive predictive value of 89.2%, negative predictive value of 81.1% in predicting diagnosis and prognosis of sepsis.Conclusions: Eosinophil count and neutrophil - lymphocyte count ratio are simple and effective prognostic markers of sepsis with low cost.

Background: The screening tests used for pre-operative evaluation of airway to predict difficult laryngoscopy and intubation have variable diagnostic accuracy. The unanticipated poor laryngeal view is gold standard for defining difficult intubation. We aimed to find out the prevalence of difficult laryngoscopy and intubation, which airway parameter better predicts difficult intubation and whether difficult laryngoscopy is associated with difficult intubation or not.Methods: This analytic cross sectional study was conducted in 665 ASA I/II adult patients, aged 18-65, without obvious airway pathology undergoing elective surgery under general anesthesia. The pre-operative screening tests included mouth opening, modified mallampatti, ratio of height to thyromental distance, sternomentaldistance and upper lip bite test. Cormack-Lehane grade III/ IV was defined as difficult laryngoscopy and potentially difficult intubation. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy and area under curve at 95% confidence interval was calculated for all five screening tests. Results: The prevalence of difficult laryngoscopy and intubation was 6.6% (44 cases). The upper lip bite test because of its highest specificity, positive predictive value, negative predictive value, accuracy and area under curve (99.7%; 93.9%; 99.7%; 95.2%; 85.1% respectively) with moderate level of sensitivity (70.5%) was better predictor of difficult intubation than other tests. The difficult laryngoscopy was associated with difficult intubation (p=0.00).Conclusions: The prevalence of difficult laryngoscopy and intubation was 6.6%.The upper lip bite test was a better predictor of difficult intubation and there was a significant association of difficult laryngoscopy with difficult intubation.Keywords: Difficult laryngoscopy and intubation; screening tests; upper lip bite test.

Background: Objective of the study was to evaluate ovarian crescent sign (OCS) as a sonographic parameter for prediction of ovarian cancer in adnexal masses suspicious of ovarian malignancy and to compare it with risk of malignancy index (RMI).Methods: Presence of OCS and calculation of RMI was done for 50 cases of adnexal masses scheduled to undergo surgery taking histopathology as gold standard.Results: 18% (9/50) of adnexal masses were malignant. OCS was absent in all malignant lesions, giving a sensitivity and negative predictive value of 100%. OCS was present in 33/41 of benign masses (specificity 80.4%). Relation of OCS to mass size<10 cm and menopausal status was significant (p<0.001). RMI≥200 could not diagnose malignancy in 4/9 cases (sensitivity 55.5%). RMI had specificity and negative predictive value of 95.1% and 90.7% respectively. Combining OCS and RMI had a lower specificity. Sequential application using OCS as first node and RMI as second node failed to diagnose 44.4% (4/9) cases as malignant.Conclusions: OCS is cheaper, easy to perform and appears to be a better test than RMI to differentiate between benign and early-stage malignant ovarian tumors. It can be used for triaging patient for referral.

Abstract Objectives To evaluate the value of liquid-based cell examination combined with human papillomavirus (HPV) genotypes in the detection of cervical intraepithelial neoplasia. Methods A total of 21,155 patients who had undergone cytology, HPV genotypes and colposcopy-guided biopsy were grouped into three groups. Sensitivity, specificity, positive predictive value, and negative predictive value of the test methods of the three groups were compared. Results In the age group of less than 50 years, the sensitivity of HPV genotype testing was significantly higher than that of liquid-based cytology. The specificity of liquid-based cytology was significantly higher in all age groups than that of HPV genotype testing. The positive predictive value of each test index was higher in the age group less than 30 years, and the negative predictive value was higher in the 30–50-year age groups. In different age groups, liquid-based cytology and HPV genotype combined method can improve the sensitivity of detection and negative predictive values. Conclusions The HPV test has higher sensitivity and negative predictive value, and the cytology method is relatively specific and less sensitive. The combined method has better sensitivity and negative predictive value.

Objectives: Cervical cancer is a very common and lethal condition; however, owing to longstanding premalignant lesions, it is possible to prevent morbidity and mortality by screening tests. Pap smear, colposcopy, and biopsy are among the main modalities in this regard, however there is no consensus on the diagnostic utility of the first 2 methods. This study sought to examine the diagnostic utility of Pap smear, colposcopy, and cytology in evaluating the non-benign cervical lesions. Materials and Methods: A cross-sectional study was carried out between 2014 and 2016 in an out-patient setting at Alzahra teaching hospital of Tabriz University of Medical Sciences. After obtaining informed consent, all 315 participants with abnormal Pap test underwent colposcopy and biopsy from the abnormal areas. Cervical biopsy was considered as a gold standard and the diagnostic values of Pap smear and colposcopy were individually compared by calculating sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio. Results: The mean age of patients was 38.49±10.31 years (17-68 years). On the basis of biopsy findings, non-benign cervical lesions were present in 31 cases (9.8%). Accordingly, the sensitivity, specificity, positive predictive value, negative predictive value, and positive likelihood ratio of Pap smear in revealing non-benign cervical lesions were 77.4%, 69.7%, 21.8%, 95.6%, 70.7%, and 2.55%, and for colposcopy, were 90.3%, 90.9%, 51.9%, 98.9%, 90.8%, and 99.2%, respectively. Conclusions: Based on our results, the colposcopy is a sensitive and specific method in differentiating benign cervical lesions from non-benign cervical lesions. The accuracy of Pap smear is intermediate in this regard, and the utility is limited. Therefore, this method should not be considered as the main criterion for decision making.
