Objectives The aim of this study was to develop age-specific nomograms for antral follicle count (AFC) in fertile and infertile Indian women and (2) to compare the influence of age on AFC in both groups. Setting and Design It is a prospective cross-sectional study in a tertiary-care hospital in north-central India. Methods and Material One-thousand four-hundred seventy-eight fertile and 1,447 infertile women (primary infertility) of reproductive age (18-49 years) were recruited. One-thousand one-hundred eighty-one fertile and 1,083 infertile women fulfilled the selection criteria for the study. Transvaginal ultrasonography was done on the second or third day of the menstrual cycle. Statistical Analysis Age-specific nomograms for AFC were built for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles in both groups. Correlation and regression analysis was done to estimate the relationship between the study variables. Statistical analysis was done by using IBM SPSS Statistics for Windows, version 20. Results At every age, each percentile value of AFC was lower in infertile than in fertile women. The decline of AFC with increasing age was linear in both fertile ( r = - 0.431, p < 0.001) and infertile ( r = - 0.520, p < 0.001) women; however, the rate was higher in the latter (0.50 follicle/year) than in former (0.44 follicle/year) group. The variation in AFC explained by age was 16.3% in fertile and 22.7% in infertile women. Conclusion AFC decreased linearly with advancing age in both fertile and infertile women, but more rapidly in the latter. The age only modestly explained the decline of AFC. The age-specific percentile thresholds for AFC should be used instead of age-independent constant thresholds in infertility counselling.

Background and Objective: The prevalence of adenomyosis of the uterus varies from 5% to 70%, and there is no clear consensus on its imaging diagnostic criteria. The objective of this study was to evaluate the role of transvaginal sonography (TVS), combined TVS and color Doppler (TVS-CD), and magnetic resonance imaging (MRI) in the diagnosis of adenomyosis. Materials and Methods: This was a tertiary care hospital-based prospective study, in which 365 clinically suspected cases of adenomyosis were enrolled. All three types of imaging (TVS, TVS-CD, and MRI) were done in 233/365 patients, followed by hysterectomy in 50. Imaging features were correlated with the histopathological examination (HPE), which was taken as the gold standard for the diagnosis. The diagnostic performance of each imaging modality was assessed. Results: Among patients who underwent hysterectomy, 36/50 (72%) had adenomyosis on HPE, with or without associated benign gynecological abnormalities. Sensitivity, specificity, positive predictive value (PPV), negative PV (NPV), and diagnostic accuracy (DA) of MRI were higher than that of TVS-CD (91.67% vs. 77.78%, 85.71% vs. 78.57%, 94.29% vs. 90.32%, 80% vs. 57.89%, and 90% vs. 78%, respectively). TVS alone had lower diagnostic performance (specificity: 64.29%, PPV 84.85%, NPV 52.94%, and DA74%) than TVS-CD, but equal sensitivity (77.78%). Heterogeneous myometrium was the most sensitive (80.56%), while myometrial cyst was the most specific (92.86%) TVS feature. The maximum junctional zone thickness ≥12 mm was the most sensitive (97.22%), while the hyperintense myometrial focus was the most specific (100%) MRI feature. Conclusion: TVS-CD should be used as an initial diagnostic imaging modality in clinically suspected cases of adenomyosis; however, MRI due to better diagnostic efficacy should be the imaging modality of choice before subjecting such patients to hysterectomy.

Low birth weight (LBW) is a leading cause of newborn's mortality however the underlying defects in cellular immunity and immune mechanisms leading to severe neonatal infections in term LBW (tLBW) newborns are not well understood. Neutrophil extracellular traps (NETs), or NETosis, is an innate immune defense mechanism of neutrophils involved in trapping and killing of microbes. The efficiency of NET formation in cord blood derived neutrophils of tLBW and normal birth weight (NBW) newborns in the presence of toll like receptor (TLR) agonist inductions was evaluated. The NET formation was observed to be substantially impaired in tLBW newborns along with NET proteins expression, extracellular deoxyribonucleic acid (DNA) release and reactive oxygen species generation. The placental tissues from tLBW newborns delivery also showed minimal NETosis. These findings suggest impaired NET formation to be an important factor underlying the deficient immune status of tLBW newborns making them susceptible to life- threatening infections.

The objective of this investigation is to provide framework to construct a threefold mixture model and its shifted version using Weibull, lognormal, and gamma distributions. The proposed models are examined by establishing the statistical and reliability indices. The parameter estimation using the maximum likelihood estimation method (MLE) and expectation-maximization has been proposed. The usefulness of the shifted mixture models by fitting them into the actual data set has revealed. The goodness-of-fit tests are used to compare the mixture models for the real-life data. Based on statistical testing, it is established that for small data set, shifted mixture model is the best fitted model in comparison with other single and mixed mixture distributions.

Maintaining a high-level reliability and efficiency without interruption are the key concerns for many real-time machining systems. Using the redundancy and repair facility features, we develop a double retrial orbit queueing model for the fault-tolerant machining system (FTMS) operating under the restriction of admission of repair jobs based on threshold policy and working vacation. The provision of primary and secondary orbits is made so that the failed units can wait there based on the facility available in case the repairman is occupied. From the orbits, the failed units retry to get the repairman free so that the repair job can be accomplished. Chapman-Kolmogorov equations for the system states of FTMS have been constructed to evaluate the transient reliability and queueing indices using the spectral technique. The sensitivity along with the relative sensitivity analysis of crucial system parameters, have facilitated. The impacts of parameter variability on the system metrics and total expected cost are examined for illustrative examples.

Purpose: To correlate the clinical, hormonal, biochemical and ultrasound parameters in adolescent patients with polycystic ovarian syndrome (PCOS) and to compare them with adult patients. Methods: This was a prospective, correlational study. 50 adult (20-35 years) and 50 adolescent patients (15-19 years) who had features of PCOS (Rotterdam Criteria, 2003) were selected. The control group comprised of 50 women of same age in each group with normal parameters. Pelvic ultrasound was done in early follicular phase (3-5th day of menstrual cycle). Assessment of hormonal and biochemical parameters (LH/FSH ratio, free testosterone level, lipid profile and fasting glucose/insulin ratio) and grey-scale ultrasound was done. Results: No significant difference was observed in menstrual pattern in adults and adolescents with PCOS. The mean values of serum LH/FSH ratio and free testosterone were significantly higher in both adult and adolescent PCOS patients as compared to their controls (p < 0.001). The mean value of serum insulin was significantly higher (p < 0.001) with positive correlation (adult: r = 0.655, p < 0.01; adolescent: r = 0.451, p < 0.01) of serum insulin with free testosterone. Hyperandrogenemia without hyperinsulinemia was found in 56% adolescent and 60% adult PCOS patients. 82% adolescent and 88% adult PCOS patients showed multiple follicles (> 5) on ultrasound. The ovarian morphology had positive correlation with serum LH and free testosterone. The mean ovarian volume was significantly higher in adult (10.48 ± 4.38 vs. 4.17 ± 0.91) and adolescent (11.08 ± 5.82 vs. 4.23 ± 0.89) PCOS patients, when compared with controls, respectively. Conclusion: No statistically significant difference was noted in PCOS between adults and adolescents.

Female genital tuberculosis (FGTB) can be asymptomatic or even masquerade as other gynecological conditions. Conventional methods of FGTB diagnosis include various imaging, bacteriological, molecular, and pathological techniques that are only positive in a small percentage of patients, leaving many cases with undiagnosed condition. In the absence of a perfect diagnostic method, composite reference standards (CRSs) have been advocated in this diagnostic study. This study assesses the agreement between traditional diagnostic modalities using CRS and prevalent TB groups among different fallopian tube infertility manifestations. A total of 86 women with primary and secondary infertility were included in the study and subjected to bacteriological, pathological, and radiological examination for the diagnosis of FGTB. Results were evaluated statistically for concordance of the diagnostic tests to the CRS by sensitivity and specificity, while PPV and NPV were calculated for the performance of diagnostic tests of FGTB. We observed that 11.2% of women were found to be true positives by means of CRS. The positive findings by CRS were as follows: ultrasonography (13.9%), laparoscopy (14%), hysteroscopy (12%), GeneXpert (4.8%), culture (4.8%), polymerase chain reaction (4.8%), and histopathology (6.4%). GeneXpert and culture were found to have a perfect agreement with CRS. Hysterosalpingography, laparoscopy, and hysteroscopy have a fair agreement with CRS. Out of 43 women with tubal factor infertility, 6 women were found in the definitive TB group with mixed conditions of tubal manifestations. This study evaluates and demonstrates the reliability of the collective assessment of various diagnostic methods with CRS findings that help in identifying different TB groups of genital tuberculosis patients from all infertile patients by applying the criteria of CRS.

In this study, fuzzy modeling and service control based on optimal N-policy for fault tolerance system have been investigated. The impacts of failures and recovery along with the reboot process are taken into account for the assessment of performance indices of the system operating under redundancy and provision of maintainability. The non-Markovian M/G/1 model of the fault-tolerant system with vacationing server is developed by using the supplementary variable to represent the remaining time to repair and further employing recursive approach. The parametric non-linear programming is used to derive fuzzy performance metrics. The sensitiveness of parameters concerning system indices is done. The cost function is framed to obtain the optimal descriptors and minimal cost using harmony search.

Speech recognition is a subjective occurrence. This work proposes a novel stochastic deep resilient network(SDRN) for speech recognition. It uses a deep neural network (DNN) for classification to predict the input speech signal. The hidden layers of DNN and its neurons are additionally optimized to reduce the computation time by using a neural-based opposition whale optimization algorithm (NOWOA). The novelty of the SDRN network is in using NOWOA to recognize large vocabulary isolated and continuous speech signals. The trained DNN features are then utilized for predicting isolated and continuous speech signals. The standard database is used for training and testing. The real-time data (recorded in ambient condition) for isolated words and continuous speech signals are additionally used for validation to increase the accuracy of the SDRN network. The proposed methodology unveils an accuracy of 99.6% and 98.1% for isolated words (standard and real-time) database and 98.7% for continuous speech signal (real-time). The obtained results exhibit the supremacy of SDRN over other techniques.

BACKGROUND: The critically ill obstetric patient represents a challenge that usually requires a multidisciplinary approach. Lack of awareness and the absence of regular antenatal care make the critically ill patients to be referred late and sometimes in moribund conditions. The objective of the present study is to determine the incidence, predictors and outcome of obstetric ICU admissions. METHODS: This retrospective study was conducted over a period of 2 year from July 2015 to June 2017 in Department of Obstetrics and Gynecology at Institute of Medical Sciences, BHU, Varanasi, India. RESULTS: Out of a total of 4986 deliveries, 756 patients underwent HDU admission, while 92 obstetric patients were admitted to ICU during this study period. Maximum number of patients (73.91%) were in the age-group of 20-35 years, 64.13% of patients constitute lower socioeconomic status group, 68.47% of patients reside in rural area and there was inadequacy in receiving antenatal care in case of 60.86% of patients. Maximum number of patients were admitted for a period of 4-7 days. Blood transfusion (64.1%), the use of inotropic drugs (45.6%), central line placement (44.5%) and mechanical ventilation (26.08%) were the major interventions performed in ICU. Obstetric hemorrhage was found to be the most frequent clinical diagnosis leading to ICU admission (31.5%) followed by hypertensive disorders (25%). CONCLUSION: In addition to timely referral, health education and training of health professionals may improve clinical outcome and better obstetric practice, especially in countries like India. Obstetric ICU dedicated for the management of only obstetric patients should be constructed in order to compensate for heavy burden critically ill women.

BACKGROUND: Polycystic ovarian syndrome (PCOS), a commonly prevalent endocrinopathy among reproductive age group women, is most often associated with obesity. Increased insulin resistance appears to be the central pathophysiologic mechanism responsible for various complications of PCOS. This makes 'weight loss' as the first-line treatment approach in PCOS. So various trials have tried to compare metformin (an insulin-sensitizing agent) and orlistat (an anti-obesity drug) aiming to achieve weight loss and hence higher ovulation rate for the group of obese PCOS patients. Keeping an eye on all these background facts, we designed this systematic review and metaanalysis to compare the effects of metformin and orlistat on various aspects of PCOS and to pick the better among the two drugs. MATERIALS AND METHODS: This is a systemic review of randomized control trials that studied the effectiveness of orlistat versus metformin in terms of improvement in ovulation rate, weight loss, lipid profile, etc. Systematic literature search over the period January 2000-December 2016 was performed in the following electronic databases: Medline, embase, google scholar, pubmed and The Cochrane Library and only randomized controlled clinical trials were included in our study. All authors carefully went through all sources of information independently. RESULTS: According to this study, weight loss, testosterone level after 4 weeks of treatment, total serum cholesterol and triglyceride level showed significant fall in orlistat-treated group. CONCLUSION: Our review shows that orlistat is a more effective drug than metformin and should be the preferred drug in obese PCOS in combination with weight loss.

BACKGROUND: Invasive placental disorders are potentially life-threatening. Its diagnosis and evaluation of degree of invasiveness is vital in surgical and treatment planning. PURPOSE: To compare the role of various imaging modalities used in current practice for evaluation of invasive placental disorders, and evaluate the validity of certain imaging signs for prediction of invasive placenta. MATERIAL AND METHODS: Twenty-two patients, which were clinically stratified as a risk group for underlying invasive placental abnormality, underwent Doppler sonography and magnetic resonance imaging (MRI). Abnormal placental invasiveness was assessed using various Doppler sonography and MRI signs described in the existing literature. We systematically evaluated the utility of each of these modalities and signs, and compared the roles played by them separately and in combination. All the cases were correlated with surgical and pathological findings. RESULTS: Nine patients had surgical and pathological confirmation of placental adhesive disorders, of which eight were predicted correctly by MRI (true positive) while one was misdiagnosed as normal placenta (false negative). All the nine cases were correctly identified by Doppler sonography. MRI was more accurate in predicting bladder invasion, identifying 5/6 cases. CONCLUSION: Both MRI and Doppler sonography are useful for detection of invasive placental disorders. However, MRI is a better predictor of bladder invasion.

Neoplastic lesions of the fallopian tube are rarely seen by surgical pathologists. Haemangioma of the fallopian tube is an extremely rare benign neoplasm. A 30-year-old lady with polymenorrhea and dysmenorrhea underwent hysterectomy and bilateral salpingo-oophorectomy. Her left fallopian tube showed a 2mm sized solid nodule in the wall. Histopathological examination revealed a well-defined vascular lesion in the left fallopian tube, consistent with capillary haemangioma. The vascular endothelium was highlighted by CD34 immunostaining. Our literature review has identified 10 cases of cavernous haemangioma of the fallopian tube. To the best of our knowledge, we report the first ever case of capillary haemangioma of the fallopian tube. This is also the smallest detected haemangioma in the fallopian tube.

BACKGROUND: Antenatal diagnosis of the invasiveness of a placenta percreta helps in planning the surgical approach, reducing blood loss and morbidity. Doppler sonography is the mainstay diagnostic modality with a sensitivity of 80-95 %. With the advent of high magnetic field MRI techniques, there has been recent interest in evaluation of placenta by MRI. On an extensive PUBMED search, we could not find any citations describing imaging, ultrasound, or MRI features to evaluate vesical wall invasion by placenta percreta. PURPOSE: We attempt to evaluate transmyometrial vesical wall invasion by placenta percreta using chemical shift artifact as a marker of intact bladder-myometrial interface on steady-state MRI sequences. MATERIALS AND METHODS: This is a prospective observational study, conducted at a university hospital. We have compiled clinico-radiological criteria for diagnosis of invasive placentae based on the existing body of evidences, in four patients. We further go on to analyze a specific proposed sign on a newly introduced MR imaging sequence i.e., loss of chemical shift artifact (India ink line) on steady-state GRE sequence (TrueFISP), to diagnose transmyometrial vesical invasion in placenta percreta. RESULTS: Though the sample size is small, the sensitivity, specificity, positive, and negative predictive value of the proposed sign for the purpose was 100 %. CONCLUSIONSS: Loss of chemical shift artifact (India ink line) on steady-state GRE sequences at the vesico-myometrial junction in case of invasive placentae confirms vesical wall invasion, a prospective diagnoses of which can help in planning the surgical protocol and preventing potentially fatal blood loss.

A surgical swab retained in the body after surgery is known as 'Gossypiboma'. The purpose of this report is to highlight an intramural vesical gossypiboma mimicking an invasive adnexal malignancy. A 28-year-old multiparous, with open-tubal ligation three years ago, presented with painless hematuria and a nontender mass on vaginal examination. USG suggested 'pelvic endometriosis' infiltrating into the bladder and cystoscopy showed no intraluminal extension of the mass. Contrast-enhanced computed tomography (CECT) and magnetic resonance imaging (MRI) misdiagnosed it as invasive malignancy of the fallopian tube. Exploratory laparotomy found it to be an intramural vesical gossypiboma. A pelvic gossypiboma infiltrating into the wall of the urinary bladder may easily be misinterpreted as an invasive pelvic malignancy on imaging and may make one consider unwarranted radical surgery.

BACKGROUND: Stress urinary incontinence (SUI) is a prevalent problem within the female population with associated high psycho-social impact. Transobturator tape procedure is a well-established procedure to treat the same, but the results may be influenced by various preoperative demographic and clinical factors. PATIENTS AND METHODS: The study group comprised of 50 female patients with genuine SUI, who were then divided into subgroups based on demographic and clinical factors. Outcomes were compared between these subgroups at 6 and 12 months using self-reported questionnaires and provocative stress test. RESULTS: Our results show positive correlation with statistically significant better surgical outcomes in premenopausal patients, patients aged <50 years and those having urethral mobility > 30 degrees. Statistically significant poor outcomes were seen in those having undergone hysterectomy or Caesarean section. No correlation was found with history of smoking or the patient's body mass index. CONCLUSIONS: In conclusion, the transobturator tape procedure appears to be more effective in premenopausal women, women aged < 50 years, women without history of hysterectomy/lower section Caesarean section, and presence of urethral hypermobility > 30 degrees. On the other hand, outcomes do not appear to be influenced by the patient's body mass index or smoking status.

PURPOSE: Urodynamic studies are commonly performed as part of the preoperative work-up of patients undergoing surgery for stress urinary incontinence (SUI). We aimed to assess the extent to which these urodynamic parameters influence patient selection and postoperative outcomes. MATERIALS AND METHODS: Patients presenting with SUI were randomly assigned to two groups: one undergoing office evaluation only and the other with a preoperative urodynamic work-up. Patients with unfavorable urodynamic parameters (detrusor overactivity [DO] and/or Valsalva leak point pressure [VLPP]<60 cm H2O and/or maximum urethral closure pressure [MUCP]<20 cm H2O) were excluded from the urodynamic testing group. All patients in both groups underwent the transobturator midurethral sling procedure. Evaluation for treatment success (reductions in urogenital distress inventory and incontinence impact questionnaire scoring along with absent positive stress test) was done at 6 months and 1 year postoperatively. RESULTS: A total of 72 patients were evaluated. After 12 patients with any one or more of the abnormal urodynamic parameters were excluded, 30 patients were finally recruited in each of the "urodynamic testing" and "office evaluation only" groups. At both the 6- and the 12-month follow-ups, treatment outcomes (reduction in scores and positive provocative stress test) were significantly better in the urodynamic testing group than in the office evaluation only group (p-values significant for all outcomes). CONCLUSIONS: Our findings showed statistically significantly better treatment outcomes in the urodynamic group (after excluding those with poor prognostic indicators such as DO, low VLPP, and MUCP) than in the office evaluation only group. We recommend exploiting the prognostic value of these urodynamic parameters for patient counseling and treatment decisions.

BACKGROUND: Antral follicle count (AFC) has been labeled as the most accurate biomarker to assess female fecundity. Unfortunately, no baseline Indian data exists, and we continue using surrogate values from the Western literature (inferred from studies on women, grossly different than Indian women in morphology and genetic makeup). AIMS: (1) To establish the role of AFC as a function of ovarian reserve in fertility-proven and in subfertile Indian women. (2) To establish baseline cut-off AFC values for Indian women. SETTINGS AND DESIGN: Prospective observational case-control study. MATERIALS AND METHODS: Thirty patients undergoing workup for infertility were included and compared to equal number of controls (women with proven fertility). The basal ovarian volume and AFC were measured by endovaginal. USG the relevant clinical data and hormonal assays were charted for every patient. STATISTICAL ANALYSIS USED: SPSS platform was used to perform the Student's t-test and Mann-Whitney U-test for intergroup comparisons. Correlations were determined by Pearson's ranked correlation coefficient. RESULTS: Regression analysis revealed the highest correlation of AFC and age in fertile and infertile patients with difference in mean AFC of both the groups. Comparison of the data recorded for cases and controls showed no significant difference in the mean ovarian volume. CONCLUSIONS: AFC has the closest association with chronological age in normal and infertile Indian women. The same is lower in infertile women than in matched controls. Baseline and cut-off values in Indian women are lower than that mentioned in the Western literature.
