The majority of efficient market research to date has focused on developed markets like United States and European securities market. Not much research has been done on strong form of the efficient market hypothesis in developing countries markets like India. The efficient market hypothesis suggests that stock markets are "information efficient", i.e., any new information relevant to the market is spontaneously reflected in the stock prices, so nobody can use such information to consistently earn abnormally high returns. This paper shows that the Indian market is strong form efficient to the extent that mutual fund managers could not out perform randomly constructed portfolios of index stocks for the period 2003-2007. This implies that an investor can build his/her own portfolio without any expert guidance and still earn returns comparable to professionally managed funds.

Introduction: Ultrasound (US) elastography is an emerging technique that can be used during breast US examination. Guidelines recommend mammographic screening and US for diagnosis of breast cancer. The specificity of these techniques is not high enough to prevent unnecessary biopsies. Hence there is need for a more specific technique to overcome this problem. This study aimed to evaluate the value of strain elastography (SE) for breast lesions. Materials and Methods: In this cross sectional observational study over 18 months, 60 women with palpable breast lumps were evaluated with conventional US and SE. Results obtained were correlated with histopathological findings for statistical analysis. Result: A statistically significant correlation was found between SE and histopathological outcome with a p value of 0.03(<0.05). The positive predictive value (PPV) was 76.92% and the negative predictive value (NPV) was 76.47% with Chi square= 8.4. Conclusion: Ultrasound with SE can substantially improve the possibility of differentiating benign from malignant breast lesions thereby limiting recourse to biopsy and considerably reducing the number of benign breast biopsy diagnoses.

Congenital malformations of the female genital tract occur in about 8-10% of all women. The unicornuate uterus is a result of partial or complete agenesis of one of the paired Mullerian ducts. It could be a true unicornuate uterus or along with a rudimentary horn, which may be functional. When the rudimentary functional horn is non-communicating, most patients become symptomatic after menarche or present with pregnancy related problems. Three clinical presentations of unicornuate uterus with non-communicating rudimentary horn encountered in last one year are described. The first case was of unruptured rudimentary horn pregnancy of 11-12 weeks. Second case had rudimentary horn removed as an adolescent due to intractable pain, but later main uterus harboured an uneventful pregnancy. Case three had two early abortions, followed by term caesarean section for fetal distress. With advent of ultrasonography and other imaging techniques, the diagnosis and management of unicornuate uterus and its variations is possible. The functional rudimentary horn if symptomatic must be removed along with ipsilateral tube. A unicornuate uterus is associated with obstetric problems and such women should be considered as high risk pregnancy.
