[Profile of the fungal flora isolated from intensive care services]

The fungal infections are more and more frequent among the patients hospitalized in intensive care services and their diagnosis remained difficult. To return the profile of the fungal flora isolated of withdrawals coming from patients hospitalized in the services of medical and surgical intensive care of the hospital Ibn Sina of Rabat between the years 2001 and 2004. It is a retrospective survey that concerned all cases of mycosis collected in the services concerned by the investigation for every patient included, the following information are noted: sex, service of hospitalization, nature and number of withdrawals results of the direct exam and the culture and finally the identification of the infectious agent. The number of addressed withdrawals to the laboratory by the services of resuscitation tripled between the years 2001 and 2004 and the difference was statistically meaningful [p=0.01]. The observed fungal infections are almost represented by the levuroses [98.6%] and more especially the candidoses [94.3%]. More of the two third [71.8%] some urinary withdrawals were positive, has the inverse of the hemocultures with 4.4% of positivity. The urinary infections were caused mainly by Candida albicans [45.5%], C. tropicalis [15.6%] and C. glabrata [6.5%]. For what is other withdrawals, flora is dominated from afar by C. albicans [84.7%]. The fungal flora isolated by the patients hospitalized in resuscitation is essentially represented by the kind Candida with the three main cash: C. albicans that remains predominant consistent of C. tropicalis and C. glabrata

Hydatid cyst of lung confrontation surgery-serology

Because the serology keep's a place in the diagnosis of hydatid cyst of lung with radiology, different techniques are used: Complement fixation technique; electrosyneresis, agglutination, indirect immunofluorescence, Elisa, Immunoblot assay. However, their specificity and their sensitivity are not identical, and can lead to discordant results. In this study, we have compared the serological techniques results with surgical results. 44 patients were tested between 63, observed in pneumology service during 4 years [1997-2000]. For the sensitivity, Elisa[IgG] and immunofluorescence are positive in 23 patients [65%], and negative in 12 patients [34%] [the doorstep of sensitivity for Elisa[IgG] is fixed from DO=0.3]. The Elisa[IgA] is positive in 12 patients [34%], and negative in 23 patients [65%] [The doorstep of sensitivity is fixed from DO=0.2]. The electrosyneresis is positive in 16 patients [46%], and negative in 19 patients [54%]. We have the same results with literature knowing that in hydatid cyst of lung the sensitivity is low. For specificite, only Elisa[IgG] has a false positivity in two case: Thymoma and carcinoma with a low level [400-200]. This results show that the serological techniques keep's their place for the diagnosis of hydatid cyst of lung in spite of the lack of sensitivity and specificity. This lack can be compensed by using Immunoblot assay
