Investing in the stock market has never been an easy task. This paper develops a stock recommendation and trade assistance that uses the past performance of the stock to predict its future performance using linear regression model. Linear regression model has given an accuracy of 99.8% as compared to support vector machine (SVM) which resulted into an accuracy of 94.6%. Data set used under the study was extracted from the historic stock data of reliance industries limited (RIL). To analyze whether to buy or sell the stock, four financial algorithms, namely Bollinger bands, moving average convergence/divergence indicator (MACD), money flow index (MFI), and relative strength index (RSI) are employed to find the composite result. Moreover, sentiment analysis of the news depending upon the earning calls and the annual general meetings is done to provide an overall stock and market sentiment analysis. In-depth balance sheet analysis of the company is also done using various instruments to make the trade assistance more accurate. The values for WACC, D/E ratio, and NPV obtained are 14.99, 0.76, and 8.9 lakh crores for RIL.

A 31-year female, G4P2L2A1 with two previous cesarean deliveries and one dilatation and curettage, was diagnosed with cervical ectopic pregnancy of 8 weeks and two days without any cardiac activity. She had a complaint of slight pain in the abdomen without any bleeding per vagina. She was initially managed with multi-dose systemic methotrexate therapy. The value of beta-HCG decreased by about 70%. She then underwent bilateral uterine artery embolization followed by ultrasound-guided suction evacuation with descending cervical artery ligation with cervical balloon tamponade. The patient was asymptomatic throughout her hospital stay. Her beta-HCG value dropped to 10 IU/ml and usg showed empty endocervical canal on weekly follow-up.: Conservation methods like systemic methotrexate or potassium chloride, along with minimally invasive techniques like bilateral uterine artery embolization, are among the most effective and safe fertility-sparing modalities in managing cervical ectopic pregnancy. Proper case selection and availability of required infrastructure at tertiary care centers are mandatory.

Yolk sac tumors (YST) are rare and rapidly developing neoplasm presenting in young females. They are second most common germ cell tumor after dysgerminomas. Fertility preservation is an important concern in treatment of patients of YST. We present a case of 22 years nulliparous female with rapidly evolving abdominal mass. The patient underwent fertility preserving surgery with four cycles of post operative bleomycin etoposide and paclitaxel (BEP) chemotherapy and is fairly doing well. BEP chemotherapy has successfully improved the treatment outcomes of YST patients.

Nowadays, big data is available in every field due to the advent of computers and electronic devices and the advancement of technology. However, analysis of this data requires new technology as the earlier designed traditional tools and techniques are not sufficient. There is an urgent need for innovative methods and technologies to resolve issues and challenges. Soft computing approaches have proved successful in handling voluminous data and generating solutions for them. This chapter focuses on basic concepts of big data along with the fundamental of various soft computing approaches that give a basic understanding of three major soft computing paradigms to students. It further gives a combination of these approaches namely hybrid soft computing approaches. Moreover, it also poses different applications dealing with big data where soft computing approaches are being successfully used. Further, it comes out with research challenges faced by the community of researchers.

Agriculture plays a significant role in the economy of India. This makes crop yield prediction an important task to help boost India's growth. Crops are sensitive to various weather phenomena such as temperature and rainfall. Therefore, it becomes crucial to include these features when predicting the yield of a crop. Weather forecasting is a complicated process. In this work, three methods are used to forecast- ARMA (Auto Regressive Moving Average), SARIMA (Seasonal Auto Regressive Integrated Moving Average) and ARMAX (ARMA with exogenous variables). The performance of the three is compared and the best model is used to predict rainfall and temperature which are in turn used to predict the crop yield based on a fuzzy logic model.

The problem of computing the reversal distance and determining a sequence of reversals to transform a genome in molecular biology is a powerful tool to derive relationships between genes. Given two signed permutations, we need to find the shortest sequence of reversals to transform one into another. The foremost polynomial-time algorithm to calculate the reversal distance used an overlap graph formed from the permutation to find connected components and then identified graph structures like hurdles. Previous researchers have used a Union-Find structure, an $\mathbf{O}(\mathbf{n}\alpha(\mathbf{n}))$ algorithm ( $\alpha$ ->inverse Ackerman function) to determine the connected components. A linear time algorithm for finding the connected components, which was a faster implementation of the existing works was proposed later. This algorithm is applied to an unsigned extension of the signed permutation. In the first scan, cycles in a breakpoint graph were located. Then in a second scan, an overlap forest is formed which gave all the connected components of the permutation. In this paper, we optimize the existing algorithm to construct the overlap forest by reducing a scan of the unsigned permutation.

Background: Induction of labour is an indispensable part of modern obstetrics and certainly one of the most frequently performed obstetric procedure in the world. Oxytocin, being the most common inducing agent with multiple protocols being practiced, further research is required for the establishment of better protocol with optimal maternal and neonatal outcomes.Methods: Randomized comparative study including 100 term nulliparous women (randomized into high dose, group-I and low dose, group-II with 50 patients in each group) was done. High dose regimen was started with 4mu/min with increment of 4mu/min up to a maximum of 32mu/min and low dose regimen was started with 2mu/min with increment of 2mu/min up to a maximum of 32mu/min. Induction to delivery interval was the primary outcome. Secondary outcomes noted were rate of caesarean section, tachysytole with or without fetal distress, failed induction, maternal outcomes like need for instrumental vaginal delivery, PPH and choriamnionitis, neonatal outcomes like NICU admission, umbilical cord pH and apgar score.Results: There was significant reduction seen in induction to delivery interval among those induced with high dose oxytocin regimen. It was found to be 6.96±3.77 hours in group-I and 9.05±4.65 hours in group-II (p value 0.034). Though incidence of tachysystole was more in high dose regimen, it was not statistically significant. No significant difference was seen in secondary outcomes.Conclusions: On the basis of present study, high dose oxytocin regimen can be considered for induction of labour as it has same effects as that of low dose regimen with lesser induction to delivery interval.

COVID-19 is an infectious disease caused by newly discovered single stranded RNA virus of Coronaviridae family. A retrospective study conducted in ABVIMS and RML hospital, Delhi in antenatal patients with COVID-19 infection detected by RT-PCR in nasopharyngeal and oral swab. It was found that patients with mean age of 27.2 years and mean gestational age of 39 weeks, mostly asymptomatic. Three patients undergone c section for obstetrical indications, while rest delivered vaginally. COVID-19 in pregnancy in small group of cases had good feto-maternal outcome but warrants further study.

Background: Hysteroscopy a minimally invasive approach for evaluating uterine cavity, and has become an indispensable diagnostic and therapeutic procedure. The main limiting factor while performing office hysteroscopy is the level of pain or discomfort encountered during the procedure. The pain is attributed mainly to the difficulty in entering the internal cervical os with the hysteroscope and while distending uterine cavity. It could be reduced if cervix is ripened before the procedure. The purpose of this prospective observational study was to compare the effectiveness, adverse effects and surgery-related complications associated with two different doses of sublingual Misoprostol (100 and 200 µg) given 2-4 hours before hysteroscopy.Methods: A randomised comparative study was conducted in the department of Obstetrics and Gynaecology of ABVIMS and Dr. RML hospital New Delhi, from 1st November, 2018 to 31st March, 2020. One hundred and twenty women, fulfilling inclusion criteria were subjected to hysteroscopy. Women received either 100 µg (Group I) or 200 µg (Group II) of sublingual Misoprostol 2-4 hours prior to hysteroscopy. The primary outcome of the study was cervical dilatation as measured by the largest number of Hegar dilator that could be inserted without resistance at the beginning of procedure. The largest dilator that negotiated cervical canal without resistance at the beginning of procedure was recorded as the baseline cervical width. The secondary outcomes were subjective assessment of the surgeon of the ease of dilatation of cervix and adverse effects of drug (i.e. vaginal bleeding, shivering, fever and pain as measured on visual analog scale).Results: The mean baseline cervical width as measured by first Hegar dilator that could be passed through the cervical canal without resistance was 6.6±0.62 mm in group I and 6.94±1.21 mm in group II respectively (p value=0.016). Adverse effects like vaginal bleeding, shivering was more in group II compared to group I. No statistically significant difference was found between group I and II with regards to visual analog scale.Conclusions: 100 µg Misoprostol can be used for cervical ripening prior to hysteroscopy with minimal adverse effects.

Background: Infertility is defined as one year of unprotected intercourse without pregnancy. Female factor is responsible for 40-50% of cases of infertility. Uterine pathologies are the cause of infertility in as many as 15% of couples seeking treatment. The objective of this study was to evaluate the accuracy of trans-vaginal sonography (TVS) and saline infusion sonography (SIS) for detection of uterine cavity abnormalities in patients of infertility taking hysteroscopy as gold standard. Methods: A prospective comparative study was done in 60 patients of infertility. Patients were selected from gynaecology OPD of a tertiary care hospital. Patient selected underwent TVS and SIS followed by hysteroscopy for presence of uterine cavity abnormalities. The presence of uterine cavity abnormality and its type (endometrial polyp, submucous myoma, intrauterine synechiae or any other) was noted. The results of TVS and SIS were compared with hysteroscopy. Results: In 60 infertile patients, hysteroscopy revealed intrauterine pathology in 22 patients (36.7%). Among them eight had endometrial polyp and another eight patients had intrauterine synechiae. Submucous myoma was detected in five patients and one patient had thin endometrium. SIS detected eight out of 22 uterine cavity abnormalities indicating sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 36.4%, 100%, 100% and 73.1% respectively. In comparison TVS showed abnormalities in six patients only and thus had sensitivity, specificity, PPV and NPV of 27.35%, 100%, 100% and 70.4 % respectively. Sensitivity of SIS for specific lesion was least for intrauterine synechiae (12.5%) and maximum for submucous myoma (60%). Conclusions: The sensitivity of both TVS and SIS for detection of uterine cavity abnormalities in patients of infertility was low in the present study and they cannot be recommended as replacement for hysteroscopy.

Background: Ectopic pregnancy means pregnancy outside the normal uterine cavity. It is the leading cause of maternal morbidity and mortality in first trimester. Early diagnosis and timely intervention can significantly improve the outcomes.Methods: Retrospective observational study done in the department of obstetrics and gynecology ABVIMS and Dr. RML hospital, New Delhi from January 2016 to March 2019. Case records of 76 patients of confirmed ectopic pregnancy were retrieved and studied from the medical record section. The main aims were to see the clinical presentation, mode of diagnosis, predisposing risk factors; treatments offered and associated morbidity and mortality.Results: The incidence of ectopic pregnancy in present study was 1.7%, highest in 21 to 30 years age multiparous patients. 85.1% presented as acute emergencies, 75% patients had classic triad of amenorrhea, pain and bleeding. Pain was the commonest symptom in 96.1%. The commonest clinical sign was adnexal mass and tenderness. Ultrasound findings had adnexal mass in 98.7% and free fluid in 84.7% cases with empty uterus in 100%. 90.7 % case were tubal ectopic and 69.73 % were ruptured. Surgery was the main treatment modality in 96.0% cases. Salpingectomy was the commonest surgery in 80.25%. There was 0% mortality and 78.9% cases required blood transfusions, 44.7% patients had no known risk factors whereas some of the common identifiable risk factors were history of previous abortion, previous pelvic surgeries and pelvic inflammatory disease.Conclusions: ABVIMS and Dr. RML hospital is a tertiary care center so majority of patients with ectopic pregnancies presented late, as such surgery was the main treatment modality but there was 0% mortality in our study. Conservative treatments such as laparoscopy and medical management can also be offered to hemodynamically stable patients.

Background: Chronic kidney disease is a heterogeneous group of renal dysfunctions with complex and varied presentations in pregnancy. With a long asymptomatic course, timely diagnosis and management is crucial for fetomaternal wellbeing.Methods: A retrospective cohort study over a period of 3 years and 4 months included all obstetric in patients with known or newly diagnosed renal disorders. Maternal outcome was measured with regard to biochemical parameters presence /absence of proteinuria, hypertension, mode of pregnancy termination and complications. Fetal outcome was noted with respect to antenatal complications, weight, Apgar, NICU stay. Computation of results was done using percentages, mean and proportions.Results: Out of 13 women studied, 53.8% were pre-diagnosed cases of renal dysfunction and 46.2% were diagnosed during pregnancy. 38% had proteinuria at first visit and 50% remained so even after delivery. 60% had history of pregnancy induced hypertension in their previous pregnancies. Secondary hypertension and superimposed preeclampsia were seen in 30% and 38% cases respectively, with only one patient requiring magnesium sulphate prophylaxis in post-partum. Cardiac dysfunction was found to be coexisting in 15.3% cases with pre-existing renal leision. Intrauterine growth restriction was seen in 61.5% cases Average fetal weight was 2. 26kg with 30% having NICU stay. 30.6% had preterm delivery. Mode of delivery was caesarean section in 46% cases.Conclusions: Pregnancy with CKD is a high-risk pregnancy with adverse fetomaternal outcomes. For optimal pregnancy outcomes, an expert multidisciplinary team is required. With limited studies in south Asian population, there needs to be an upgradation in registry system.

For the past few decades we have seen the evolution of user interfaces from CLI (Command Line Interface) to GUI (Graphical User Interface) to the most recent NUI (Natural User Interfaces). One such example is Surface Computing. Surface computing is a new way of working with computers that moves beyond the traditional mouse-and-keyboard experience. It is a natural user interface that allows people to interact with digital content with their hands, with gestures and by putting real-world objects on the surface. Though very convenient and simple to use, the cost of this technology is one of the major hindrances in making it accessible to common users. Microsoft PixelSense is an excellent example of this technology. For making this technology cost efficient and more accessible, we have designed an interactive table. It allows two mobile phones to interact with each other, i.e. one can share mobile content just by placing two phones on the table and dragging the content from one phone to another using their fingers. Instead of the usual resistive and capacitive touchscreens used these days, it uses an imaging touch screen, i.e. image processing is used to determine the fingertip coordinates and handle data according to these coordinates thereby decreasing the cost of this technology sharply.

Background: The World Health Organization (WHO) estimates that, of 536,000 maternal deaths occurring globally each year, 136,000 take places in India. Maternal death has serious implications to the family, the society and the nation. It deprives the surviving infant of mother's care. This study was done to assess maternal mortality in a tertiary care centre in north India where large numbers of patients are referred from the peripheral centers and the rural parts. This study was done to assess the causes of maternal mortality and suggest remedial measures to reduce the same. Objective of present study was to assess the causes of maternal death over a period of one year at G.M.C Amritsar, India.Methods: A retrospective hospital based study of 22 maternal deaths over a period of 1 year from June 2012 to June 2013. The information regarding demographic profile and reproductive parameters were collected and results were analyzed.Results: Over the study period, there were 22 deaths and 7272 live births (Majority were referral from other districts all over Punjab). Most common direct cause of maternal mortality was haemorrhage and anemia was the most common indirect cause. Most maternal deaths were seen in patients from rural areas, unbooked, illiterate patients and patients from low socioeconomic status.Conclusions: Proper health education should be given to the women; early registration of antenatal cases should be done which allows for rapid diagnosis and treatment of high risk cases. Also constructing a well equipped health care facility with trained staff and prompt transport facilities for early referral can bring down the maternal mortality rate in our country.

Background: Early detection of abnormal progress and prevention of prolonged labour can significantly improve the outcome of labour. Partograph is an inexpensive tool which can provide a continuous pictorial overview of labour and is essential to monitor and manage labour. The objectives were to study the course of normal and abnormal labour and to evaluate the maternal and perinatal outcome using simple and composite WHO partogram.Methods: This was a randomized study conducted at Department of Obstetrics and Gynaecology, Government Medical College, Amritsar, a tertiary care centre in North India. 200 women with term, singleton, vertex gestation, in spontaneous labor were included in the study. In 100 cases composite partograph was plotted and in rest 100 cases simple partograph was plotted. The following outcomes were compared: labor crossing the alert and action line, augmentation of labor, rate of cesarean section, perinatal and maternal outcome.Results: The partogram crossed the alert line (p 0.008) and action lines (p 0.017), causing increased need for augmentation (p 0.034) in the composite partogram which was statistically significant. The numbers of vaginal deliveries were high (p

Background: In view of high rate of unintended pregnancy in our country, particularly in post-partum women, there is a need for reliable, effective and long-term contraception such as intrauterine device (IUCD) in post-partum women. This study was done to determine the efficacy and safety of Post-Partum Intrauterine Device (PPIUCD) and to compare the outcomes of PPIUCD insertion after vaginal delivery and caesarean section.Methods: This follow up study was carried out in the department of Obstetrics and Gynecology, Dr. R.M.L Hospital, PGIMER, New Delhi over a period of 7 month from January 2016 to July 2016. PPIUCD (cu T- 380 A) insertions were done in 136 women who fulfilled the inclusion criteria. Women having haemoglobin less than 8 gm%, rupture of membranes more than 18 hours, obstructed labour, Uterine anomalies, distorted uterine cavity by fibroid, significant postpartum haemorrhage, coagulation disorders, fever or clinical symptoms of infection during labour were excluded from the study. Post insertion counselling was done, and these women were advised to follow up at 6 weeks and then after 6 months postpartum in the family planning O.P.D. At the follow-up visit, the women were asked for any symptoms of unusual vaginal discharge, irregular or heavy bleeding per vagina, and any expulsions if noticed.Results: Total number of cases that reported for follow up in family planning OPD was 118. Therefore, 18 patients were lost in the follow up. In 58.47% women, there was no complaint. Heavy menstrual bleeding was found in 17.79% women and pelvic pain in 16.10% women. The expulsion rate was 5.08% and IUCD removal was done in 12.71% women. Though, the incidence of expulsion and removal rate was more in vaginal insertions than in caesarean insertions but this difference was not statistically significant, while the incidence of missing threads were found more in intra caesarean insertion (28% vs. 11.76% with p value

Background: Uterine leiomyoma is a common indication for hysterectomy in India. An effective medical treatment option may reduce hysterectomy associated morbidity. This study was undertaken to evaluate the effect of the Letrozole on patients with symptomatic leiomyoma in the reproductive age women.Methods: Prospective interventional study was conducted on 50 women between 30-45 years of age with menstrual or pressure symptoms on the bowel or urinary system, and having no. Of myoma ≤4 and size of single myoma ≥2 cms in diameter. They received tablet letrozole 5mg/day for 3 month, and effect of the drug on myoma volume and symptomatology were studied. Beside these, effects on uterine volume, ovarian volume, endometrial thickness and side effects of letrozole of any were also studied.Results: Average reduction of myoma volume by 47.68% and uterine volume by 19.58% was seen. Haemoglobin concentration was significantly higher at the end of study. It increased from 9.56g/dl to 10.76g/dl and overall improvement in symptomatology score was observed. Ovarian volume increased significantly from baseline mean volume of 8.18±0.51cm³ to 19.3±0.84cm³ and no significant change in endometrial thickness was observed at the end of 3 month. Sweating, hot flushes, nausea and vomiting were the main adverse effects observed and were self limiting.Conclusions: Letrozole, the aromatase inhibitor resulted in significant volume reduction of the uterus-leiomyoma structure and was effective in controlling the more frequent symptoms of this disorder with fewer side effects.

Background and Objective: Hyperprolactinemia affects the reproductive endocrine axis; however, the degree of dysfunction may vary depending on etiology. The aim of the present study was to analyze menstrual cyclicity in patients with prolactinoma and drug-induced hyperprolactinemia (DIH). Methodology: Patients with prolactinoma and DIH were retrospectively analyzed for menstrual cyclicity at presentation and response to therapy. Results: Of 128 females with hyperprolactinemia, 58 had prolactinoma (41 microadenoma and 17 macroadenoma) and 39 had DIH. Patients with prolactinoma had higher prolactin levels and increased frequency of oligomenorrhea (77.5% vs. 46%) as compared to DIH. Patients with macroprolactinoma had more severe menstrual disturbances compared to microprolactinoma. A higher percentage of patients with microprolactinoma and DIH achieved regular menstrual cycles compared to macroprolactinoma postcabergoline treatment (85% and 90% vs. 65%). There was no correlation between time to regularization of menstrual cycles with age, menstrual cycle length, duration of menstrual irregularity, or initial prolactin level in patients with prolactinoma. Linear regression analysis showed a significant association between time to regularization of menstrual cycles with time to normalization of prolactin levels (P = 0.001). Conclusion: There is a prompt restoration of menstrual cycles in patients with microprolactinoma and DIH. Patients with macroprolactinoma have more severe menstrual disturbances and lesser frequency of cycle restoration postcabergoline treatment compared to microprolactinoma and DIH.

Various studies conducted on bug repositories utilise issue reports labelled as 'bug'. Research conducted on a number of bug repositories have shown that not all issue reports labelled as 'bug' are actually bugs but can also be a request for additional feature, improvement or documentation. This not only threatens the validity of studies that have used mislabelled data but may also give wrong prediction results in future. This has necessitated need for correct labelling of issue reports. The proposed work using fuzzy logic classifier suggests improvement and also reduces the complexity. Validation of this work is done using five open source projects. Experimental results have shown that our approach gives better F-measure scores. The study also elaborated on use of issue reports from other similar projects for training a model; the impact of frequent terms from the training data and applicability of our approach to fine grained categorisation of issues.

To evaluate the accuracy of transvaginal sonography (TVS) and saline infusion sonohysterography (SIS) for detection of uterine cavity abnormalities in patients with abnormal uterine bleeding (AUB) taking hysteroscopy as the gold standard.This was a prospective study done in the department of Obstetrics and Gynecology of a tertiary care academic hospital. Sixty premenopausal and postmenopausal women who presented with AUB underwent TVS, SIS, and hysteroscopy. The presence of focal abnormality and the type of abnormality, i.e., polyp, submucous myoma, and endometrial hyperplasia, were noted. The results of TVS and SIS were compared with hysteroscopy.On hysteroscopy, 76.67 % (n = 46) patients were diagnosed with intra cavity abnormalities. SIS showed sensitivity, specificity, PPV, and NPV of 89.1, 100, 100, and 73.7 %, respectively. In comparison, TVS showed sensitivity, specificity, PPV, and NPV of 43.48, 78.57, 86.96, and 29.73 %, respectively.SIS was found to be more sensitive and specific than TVS in detection of intra cavity abnormalities.

We aimed to evaluate the predictive value of amniotic fluid index (AFI) (5) for adverse perinatal outcome in terms of cesarean section for fetal distress, birth weight, meconium staining, Apgar scores, and cord pH at birth.This was a prospective study of 200 antenatal women booked at Ram Manohar Lohia (RML) Hospital during the years 2009-2011 with gestational age between 34 and 41 weeks. The women's history, clinical examination recorded, and AFI were measured and the perinatal outcome was compared between two groups, i.e., AFI 5 and5.The cesarean section rate for fetal distress and low birth weight babies,2.5 kg, was higher in patients with oligohydramnios (p = 0.048, 0.001, respectively). There was no significant difference in meconium staining, Apgar score at 5 min7, and cord pH at birth between the two groups (p = 0.881, 0.884, 0.764, respectively).Oligohydramnios has a significant correlation with cesarean section for fetal distress and low birth weight babies.

To compare the efficacy and safety profile of two methods of labor induction i.e., intracervical dinoprostone gel (0.5 mg 8 h) and misoprostol (50 μg 4 h) for induction of labor in women with a poor Bishop’s score. Observational study. January 1st, 2009 to December 31st, 2010. A total of 329 women with unfavorable cervices induced at or near term. Two cervical ripening agent study arms were used: dinoprostone gel (193 women) and misoprostol (137 women). Induction to delivery interval, cesarean section, incidence of meconium stained liquor, FHR pattern, incidence of uterine hyperstimulation, and neonatal outcomes. The induction to delivery interval was significantly shorter in the misoprostol group as compared to the dinoprostone group (p

Developing software involves many phases such as designing, coding and testing. Once the software is released, a separate team is responsible for maintaining the software. Nowadays many researchers and users work on Open Source Software to enhance its functionalities and to mould it according to their needs. Most of the time, a user or developer wants to locate a specific feature in software for the purpose of enhancement or removing a fault, which is known as concept localization. Automatic concept localization gives relevant files to the users as per the requirement. We have implemented n-gram, an Information Retrieval model to retrieve the names of the relevant files from the source code and incorporated Control Flow Graph (CFG) which helped us to determine the files encapsulating the functionality, in the correct order. We conducted tests on numerous grounds such as different threshold values (0.4, 0.6 and 0.8), N value (2 and 3) and varying query length. On examination, we obtained recall of 74% and precision of 65% on threshold value of 0.6 using trigram (i.e. n=3). Control Flow Graph significantly contributed in improving the ranking of relevant files.

Web services technology is widely used as a solution of information by all users. Now a days, the user rely on web for the information need but the currently available search engines though using sophisticated document indexing algorithms, quite often gives a long list of results, much of which are not always relevant to the user's requirement. Since a user has a specific goal when searching for information, personalized search may provide the results that accurately satisfy user's specific goal and intent for the search. Personalization of web search is to retrieve information according to user's interests which may be inferred from user's actions, browsed documents or past query history etc. This paper conducts a survey of how personalization (if applied) can give useful knowledge to the user. Several user personalization approaches and techniques developed for the information retrieval domain are illustrated in this paper.

A 42-year-old para 2 women underwent laparotomy with a preoperative diagnosis of leiomyoma uterus and ovarian endometrioma. At laparotomy, uterus was 12-week size and bilateral tubes and ovaries were normal. There was a large friable reddish-brown mass dissecting the leaves of broad ligament with extension into pelvic cavity and retroperitoneal spaces. Total abdominal hysterectomy with bilateral salpingo-oophorectomy with resection of tumour was performed as there was concern about the possibility of malignancy. Histopathological examination revealed a cotyledonoid leiomyoma epithelioid variant. These tumours, though benign, raise the possibility of malignancy at the time of surgery due to their bizarre and sarcoma-like appearance. It is important for the pathologist and gynaecologist to be aware of this rare variant of leiomyoma to avoid an overtreatment.

Context: Maternal mortality ratio (MMR) is an indicator of effectiveness of health care facilities for women of child bearing age group. Andaman and Nicobar (A&N) group of islands are unique as they are situated 1200 km from the mainland India. Healthcare delivery for the these islands is exclusively provided and controlled by only one authority, Directorate of Health Services, A&N Islands. GB Pant Hospital, Port Blair is the only referral hospital with round the clock specialists and surgical services. Aims: To estimate the MMR in A&N islands from 2001 to 2010, and study the causes of maternal mortality. Settings and Design: Retrospective. Materials and Methods: Data for the estimation of MMR were collected from office of Registrar of Births and Deaths, Hospital and Peripheral Health Centres. Case records of maternal deaths in GB Pant Hospital were reviewed to study the causes of death. Statistical analysis used: Proportions and Ratios. Results: Ten years average MMR for the entire island was 85.42. Analysis of 30 maternal deaths in GB Pant Hospital showed that 63.3% were due to direct obstetric causes (eclampsia 30%, hemorrhage 23.33%, sepsis 6.66%, and 3.33% amniotic fluid embolism). Of the indirect causes, anemia was the commonest (16.66%). Conclusions: The MMR of A&N islands is much lower than the national average of 250. Direct obstetric causes accounted for more than half of maternal deaths 63.33%.
