Abstract

[automatically translated] Introduction. In recent years there has been a general increase and to an ever wider diffusion, both in hospital and community, of multiresistant microorganisms. In the absence and waiting for higher effective pharmacological treatments attention must be used to the realization of targeted surveillance strategies. The first isolation of a strain of Staphylococcus aureus meticillinoresistente (MRSA) dates back to 1961 and was followed by a sudden and dramatic spread in hospitals around the world. To date MRSA is recognized as one of the main causative agents of nosocomial infections and isolation percentages vary from country to country in a remarkable fashion. In Europe, the prevalence of MRSA essentially increases from north to south, reaching values between 40% and 50% in Italy. Around 1990 he recorded the first isolation of MRSA in the community and has since spread and in community insulations are increasingly common. Within a few years, MRSA strains have shown a remarkable evolutionary and adaptive capacity that raises many concerns. Today it is customary to distinguish between HA-MRSA and CA-MRSA used to groped a more rapid and targeted approach to the problem but in our reality is not always so clear. Methods. The study that we carried out at the Department of Sciences for the Promotion of Health and Maternal-Infantile 'G. D'Alessandro 'has as its objective the evaluation of the epidemiology of MRSA in both hospital and community by comparing the movement of MRSA within dell'UTIN (Neonatal Intensive Care Unit) of the Hospital' Paolo Giaccone ' and that the municipal nursery schools Palermo. We have collected a total of about 1,000 nasal swabs from the children of kindergartens and newborns admitted to NICU. All were analyzed for the presence of MRSA. Results. The MRSA isolation rate is about 10% of the swabs from dall'UTIN compared to 2% of the swabs taken in kindergartens. The isolation frequency of MSSA strains is higher but very similar in both contexts and equal to 12% and 15%. The activity in the NICU is part of a surveillance program started in June 2009 and to date has been very positive by reducing the frequency of colonization by MRSA from 27% (2009) to 10% (2013). Conclusions. Care facilities represent a context particularly at risk for the movement of multi-resistant micro-organisms and as such they must always be kept under close observation. Active surveillance of colonization allows in a simple, inexpensive and timely monitor the main agents responsible for care-associated infections. The comparison with the situation in the community has been able to understand more accurately the epidemiology of MRSA. Surveillance is necessary to achieve prevention and control interventions targeted and effective.
