In vivo corrosion and in vitro microleakage of a gallium based and a high copper amalgam alloys were evaluated. Twenty-five primary molars each were restored with Galloy and DPI alloy respectively and evaluated, over a period of three months, for various aspects of corrosion in the oral cavity. Additionally ten primary molars were utilized for evaluation of microleakage by dye penetration after having them restored with the two materials. Gallium alloy restorations showed better marginal adaptation, clinically when compared to amalgam restorations. No significant difference was observed for the degree of microleakage around gallium alloy and amalgam restorations.

The main focus of the paper is on the development of a unified analytical model for predicting the rate of uniform corrosion for commonly used engineering metals exposed to the atmosphere. A cumulative damage function model is proposed on the presumption that the corrosion is primarily due to the presence of critical corrosive agents in the atmosphere. The model incorporates sensitivity factors to account for the corrosion sensitivity of the metal with respect to the critical corrosive agents and the presence of other corrosive agents. Predictions of the uniform corrosion rate of metallic structures made of iron, mild steel, carbon steel, and zinc are presented. Results predicted using the model are compared with the values expected for mild steel using the data available in the Corrosion Map of India.CEST/2153

Aim: Lip prints are unique for any individual. The potential of lip prints as one of the biometric records to determine the identity has been well-recognized. However, studies focused on their reliability by comparing the developed latent lip prints were scarce. This study focused on the reliability of the lip prints for the personal identification by comparing the registered lip prints with the developed latent lip prints made on the porcelain cups. Materials and methods: Samples of 102 subjects (52 males and 50 females) within the age group of 18-30 years were included. Latent and superimposed lip impressions were made on a standard porcelain cup. The latent prints were developed with the fingerprint powder. Then, the lip prints with lip rouge were registered on a transparent adhesive tape. Both the developed latent lip prints and the registered lip prints were photographed with a standard ruler using the digital camera and were compared. The lip prints were classified with the scheme proposed by Tsuchihashi. The statistical analysis was done using the Pearson Chi-square test (IBM SPSS version 20) with a p value of 0.05. Results: The lip prints were unique to any individual irrespective of the gender variation. Their interpretation of comparing the digital pictures confirmed the presence of unique patterns and the possibility of the feature extraction similar to the fingerprints. Type III was the most frequent pattern observed in the study group. Conclusion:We conclude that the lip prints are highly reliable as a biometric record due to their uniqueness. The lip prints have demonstrated enough evidence that is intentionally registered and the developed latent prints were compared, which can be applied as one of the easiest and simplest methods for comparison. Yet, the authenticity of the lip print is in the preliminary level and need more systematic studies to be accepted for the legal disputes. Clinical significance: The study result can strengthen the reliability of the lip prints as an identification tool and discusses the future possibilities of lip print application.

Background: In1951, India became the 1st country in the world to launch family planning programme. Since then approaches for reducing population growth have taken a variety of forms but with a little success. According to National Population policy2000 the TFR to be achieved by 2010 was 2.1.Objectives: To study the knowledge, attitude and practices regarding family planning among the married women attending the urban health training centre of Narayana medical college, Nellore. Methodology: The study is conducted over a period of 3 months from Oct.2016 -Dec.2016 on 170 married women attending UHTC, NMC, Nellore and who were willing to be interviewed. The study tool is a pre-designed, semi-structured questionnaire. Data collected will be entered in MS-Excel and analysed using SPSS version 22.0. Results: Among the 170 married women the results were as follows: 50% were in the age group of 20 -29 years, 22.4% were illiterates. 75.3%women were home makers. 38.8% were married below the age of 18 years. While 67% of the women completed their families, 51.2% had 1 living son. 69% were aware of family planning. Almost 52% said decisions regarding family planning were made by husband & in-laws. There was significant association between awareness regarding family planning with age of the women, caste, education and occupation of the women, and also age at marriage and age at 1st delivery. Conclusion: awareness regarding family planning should be improved. Women should be given free hand regarding decisions concerning family planning.

Introduction Respect for patients' privacy and dignity and the maintenance of confidentiality are long-established principles of medical practice. General Medical Council has emphasised that patients have a right to expect that information about them will be held in confidence by their doctors and staff involved in their care. Confidentiality is central to the preservation of trust between doctors and their patients. Without assurances about confidentiality, patients may be reluctant to give information to the doctors, which they need in order to provide good care to the patients. The aim of this research study was to assess the patient impression on the confidentiality and privacy, maintained in maternity wards at tertiaryreferral centre of St Mary's Hospital for women and children. Materials and methods Using a structured questionnaire, patients were interviewed about privacy, dignity and confidentiality experienced during their stay in the hospital. The questionnaire did not have any questions, which would reveal the identity of the patient and was conducted in confidentiality, after their consent. Results Sixty patients returned the completed questionnaire. The survey group mainly consisted of postnatal mothers (80%) staying in the bays shared by four patients (70%). There were eight patients in the teenage group. Number of days for the stay varied from 1-20 days, with mean of 7.5 days. Conclusion Our research study focused on women's responses to their recent experience on maternity wards regarding privacy and confidentiality. It sought to gain insight into the service features the women associated with negative and positive reactions.
