[A survey of the social and health conditions of immigrants living in the city of Messina (Italy)].

From december 2002 to May 2003 a questionnaire was administered to a sample of the immigrant population living in Messina (Italy), in order to evaluate their social and health conditions. Of great interest are data revealing that nearly all immigrants, despite being regularly enrolled in the Italian National Health Service (INHS), do not utilize available services when ill. The survey identified one of the reasons for this to be insufficient visibility and accessibility of the INHS in that time period.

[Retrospective survey on epidemiologic monitoring of accidents due to professional exposure to biological agents in A.O.U. "G. Martino" of Messina, Italy)].

The management of healthcare professionals exposed to biological material which may potentially be contaminated with HIV HBVand HCV viruses, is of vital importance in acquiring precise epidemiological data regarding the type and means of exposure, and the efficacy or failure to apply recommended preventive measures. This will make it possible to assess over time which measures need to be implemented or improved. For these reasons we decided to analyze cases of occupational exposure to biological risk occurring in the University Hospital in Messina between 1998 and 2002.

[Knowledge of disinfection practices and behaviour of the nursing staff at a hospital].

The authors have carried a study on the knowledge of disinfection practices and the behaviour in operating room in order to control and prevent nosocomial infections. It is necessary for high percent of head nurses and nurses to have guidelines for the disinfection/sterilization procedures with the aim to avoid infections, but a large number of subjects don't know the correct procedures. The knowledge of a correct behaviour in the operating room is greater, although many of nursing staff don't wear the overshoes and the protective glasses.
