Inspite of high incidences of exposures to HIV or Hepatitis B positive source, good efficacy of PEP was observed with no sero-conversion. PEP for HIV was well tolerated; female HCWs were less tolerant. Study emphasized the need for creating awareness about timely reporting of incidence, achieving maximum vaccination against Hepatitis B for all HCWs and need for anti-HBS antibody titre.

IntrOductIOnImportance of Vitamin B12 in the production of DNA and RNA is been well established. Deficiency of Vitamin B12 causes macrocytic anaemia, peripheral neuropathy, dementia, weight loss, neural tube birth defects and various other adverse health effects. Recently increased prevalence of Vitamin B12 deficiency is been identified in various studies across different parts of India [1][2][3]. Easy availability of diagnostic facility to identify B12 deficient individuals, who were otherwise unidentified earlier as well as increased awareness among public causing voluntary testing of B12 levels may be some of the reasons for recently increased prevalence. Pure vegetarian diet lacking in milk or dairy product is one of the most commonly identified risk factors for development of Vitamin B12 deficiency, yet there is possibility that some newly developing but unidentified risk factors to be responsible for its recently increasing prevalence.Along with life style changes, changes have kept on occurring in people's dietary habits and type of drinking water over period of time; there is a possibility that some of these changes may be associated with recently increasing Vitamin B12 deficiency. One of the frequently questioned such factors is use of drinking water processed by Reverse Osmosis (RO) technology. With population growth and exploitation of available water sources causing scarcity of safe drinking water, mainly in developing countries, public based RO plants and home based RO units are being increasingly used. RO system very effectively removes dissolved solids as well as many microorganisms making water palatable and relatively safe to use [4][5][6]. With increased use of RO processed demineralised water, many adverse health effects are also been increasing identified. Increased cardiovascular morbidity and mortality is now been well established due to use of demineralised water low in calcium

This paper gives the idea about autocomplete predictive text search coupled with using graph database for storing various nodes. Firstly, the paper focuses on the search bar developed using web technologies that is platform independent and can be deployed on any system. It deals with the Jquery and AJAX mechanisms to give the user immediate autocomplete results before he or she has finished typing. Secondly, the paper discusses the role of a graph database technology used named Neo4j that stores nodes and orders relationships between them. The use of Cypher queries has been explained to retrieve the data from the graph database and JSON encode it on the screen where the user's current focus remains.
