title: [Intestinal parasitosis prevalence in outpatients and inpatients of Cã Granda IRCCS Foundation - Ospedale Maggiore Policlinico of Milan: data comparison between 1984-1985 and 2007-2009].
abstract: This paper evaluates the prevalence of intestinal parasitosis in a specific population over three years (2007-2009). The results were compared with published data collected from the same population in 1984-1985. During a survey from January 1st 2007 to December 31(st) 2009 a total of 2962 inpatients and outpatients were evaluated in our facility (IRCCS Foundation - Ospedale Maggiore Policlinico) for ova and protozoa stool examination (OPE) over three specimens collected alternatively for three days. 614 inpatients and outpatients were evaluated for the Graham Test (GT) over three slides collected for three days (day by day). Sixty inpatients and outpatients were also sampled for agar culture for detecting Strongyloides larvae in faeces. OPE revealed 13.26% of the patients positive for parasites; TG revealed 8.14% were positive. Overall, 16.66% of the patients were positive for Strongyloides larvae agar culture. Of the OPE trial group, only 4.2% were positive for real pathogen parasites. 1.78% of the total was affected by several parasites. Apart from the prevalence of Entamoeba histolytica/dispar and Taenia spp, which was unchanged, all other levels fell compared with the 1984 - 1985 results. New pathogens, namely Hymenolepis nana and Schistosoma mansoni, were detected during 2007-2009 period. Strongyloides stercoralis was the most frequently diagnosed helminth in 2007-2009 as in the previous time period.
