Social network is a social structure made of individuals or organizations associated with one or more types of interdependence (friendship, common interests, work, knowledge, prestige, etc.) which are the “nodes” of the network. Networks can be organized to exchange information, knowledge or financial assistance under the various interest groups in universities, workplaces and associations of citizens. Today the most popular and widely used networks are based on application of the Internet as the main ICT. Depending on the method of connection, their field of activity and expertise of those who participate in certain networks, the network can be classified into the following groups: a) Social Networks with personal physical connectivity (the citizens’ associations, transplant networks, etc.), b) Global social internet network (Facebook, Twitter, Skype), c) specific health internet social network (forums, Health Care Forums, Healthcare Industry Forum), d) The health community internet network of non professionals (DailyStrength, CaringBridge, CarePages, MyFamilyHealth), e) Scientific social internet network (BiomedExperts, ResearchGate, iMedExchange), f) Social internet network which supported professionals (HealthBoards, Spas and Hope Association of Disabled and diabetic Enurgi), g) Scientific medical internet network databases in the system of scientific and technical information (CC, Pubmed/Medline, Excerpta Medica/EMBASE, ISI Web Knowledge, EBSCO, Index Copernicus, Social Science Index, etc.). The information in the network are exchanged in real time and in a way that has until recently been impossible in real life of people in the community. Networks allow tens of thousands of specific groups of people performing a series of social, professional and educational activities in the place of living and housing, place of work or other locations where individuals are. Network provides access to information related to education, health, nutrition, drugs, procedures, etc., which gives a special emphasis on public health aspects of information, especially in the field of medicine and health care. The authors of this paper discuss the role and practical importance of social networks in improving the health and solving of health problems without the physical entrance into the health care system. Social networks have their advantages and disadvantages, benefits and costs, especially when it comes to information which within the network set unprofessional people from unreliable sources, without an adequate selection. The ethical aspect of the norms in this segment is still not adequately regulated, so any sanctions for the unauthorized and malicious use of social networks in private and other purposes in order to obtain personal gain at the expense of individuals or groups (sick or healthy, owners of certain businesses and companies, health organizations and pharmaceutical manufacturers, etc.), for which there is still no global or European codes and standards of conduct. Cyber crime is now one of the mostly present types of crime in modern times, as evidenced by numerous scandals that are happening both globally and locally.

Advances in medicine in recent decades are in significant correlation with the advances in the information technology. Modern information technologies (IT) have enabled faster, more reliable and comprehensive data collection. These technologies have started to create a large number of irrelevant information, which represents a limiting factor and a real growing gap, between the medical knowledge on one hand, and the ability of doctors to follow its growth on the other. Furthermore, in our environment, the term technology is generally reserved for its technical component. Education means, learning, teaching, or the process of acquiring skills or behavior modification through various exercises. Traditionally, medical education meant the oral, practical and more passive transferring of knowledge and skills from the educators to students and health professionals. For the clinical disciplines, of special importance are the principles, such as, “learning at bedside,” aided by the medical literature. In doing so, these techniques enable students to contact with their teachers, and to refer to the appropriate literature. The disadvantage of these educational methods is in the fact, that teachers often do not have enough time. Additionally they are not very convenient to the horizontal and vertical integration of teaching, create weak or almost no self education, as well as, low skill levels and poor integration of education with a real social environment. In this paper authors describe application of modern IT in medical education – their advantages and disadvantages comparing with traditional ways of education.

Introduction: Coronary heart disease and its etiology are complex socio-medical and clinical problem in this century. World Health Organization defined coronary artery disease as acute and chronic heart ailments due to disruption of flow and myocardial blood supply. Diseases of the cardiovascular system in spite of preventable risk factors are responsible for approximately 50% of all deaths in the developed world, and this ratio is higher in developing countries. Risk factors: Coronary heart disease risk factors can be divided in those which are not preventable such as: personal and family history of cardiovascular diseases, age and gender and preventable risk factors including: high blood pressure, elevated blood cholesterol, smoking, reduced physical activity, elevated blood sugar, increased body weight, alcohol use, psychosocial factors and nutrition. There are also newly emerging risk factors which includes increased homocysteine, thrombogenic and inflammatory factors. Prevention of coronary heart disease risk factors: The concept of risk assessment factors, their reduction, initially begun in the Framingham Heart Study and refined in other models. Primary prevention relates to changing lifestyle and influencing preventable risk factors. Numerous studies and meta-analysis showed that lifestyle modification, risk reduction factors, particularly by changing diet, stopping smoking, increasing physical activity, blood pressure control can be effective in the prevention and reduction of coronary heart disease. Primary health care physicians i.e. family physicians need to take an active role in assessment of risk factors for coronary heart disease. Conclusion: The data in this paper, based on the findings from other studies, suggest the importance of using a modified algorithm in order to estimates the overall risk of coronary disease in high-risk groups among the patients in the primary health care settings.

Summary Public health is a broad field that touches several different medical disciplines such as epidemiology, public health informatics, health statistics, environmental protection (ecology), sociology, health promotion, disease prevention and organization of health care for nosological groups of the population. In Europe and the world today is developed a fairly extensive network of scientific and professional institutions engaged in research projects, studies, organization of scientific conferences and publishing scientific and professional articles from the field of public health. Their goal is to promote scientific advances in the field of public health through the exchange of experiences of public-health professionals, training, demonstration of appropriate research models, simulation and application in medical practice.

Summary Computer technology is a reality of our modern world. It gives us a tool which can be used to help us cope with the complexity and efficiency which is often required in many areas of work. It is an erroneous assumption that it robs a situation of its human qualities. No one would deny that the use of a word processor denies the possibility of highly creative writing being produced or that computerized checkouts make the interaction skills of the checkout person irrelevant to the process of struggling with the week’s shopping once more. In many ways, the use of the computer frees the person from the drudgery of repetitive labour to allow more time and effort to be available for the more personal skills to find expression. Recording assessment data using a computer keyboard allows just as much caring communication between nurse and clients as writing it down on a form. The critical factor is not the method of recording but the interpersonal skills and motivation of the nurse. The nursing profession is at last beginning to appreciate the role which the new technology can have in improving the service provided to patients. Only by taking an active role now in the implementation of computers to clinical practice can nurses maintain control of their own professional contribution to the large complex systems at present being implemented in many health care settings. Knowledge based systems are set to become a major component in the nurse’s ability to take on this role.

CONFLICT OF INTEREST: NONE DECLARED Introduction The International classification of diseases (ICD) is the most important classification in medicine. It is used by all medical professionals. Concept The basic concept of ICD is founded on the standardization of the nomenclature for the names of diseases and their basic systematization in the hierarchically structured category. Advantages and disadvantages The health care provider institutions such as hospitals are subjects that should facilitate implementation of medical applications that follows the patient medical condition and facts connected with him. The definitive diagnosis that can be coded using ICD can be achieved after several visits of patient and rarely during the first visit. Conclusion The ICD classification is one of the oldest and most important classifications in medicine. In the scope of ICD are all fields of medicine. It is used in statistical purpose and as a coding system in medical databases.
