Prevalence of papillomaviruses, polyomaviruses, and herpesviruses in triple-negative and inflammatory breast tumors from algeria compared with other types of breast cancer tumors.

Background: The possible role of viruses in breast cancer etiology remains an unresolved question. We hypothesized that if some viruses are involved, it may be in a subgroup of breast cancers only. Epidemiological arguments drove our interest in breast cancer subgroups that are more frequent in Africa, namely inflammatory breast cancer (IBC) and triple-negative breast cancer.

Features of breast cancer in developing countries, examples from North-Africa.

Epidemiological features of breast cancer appear to be different in developing countries compared to Western countries, with notably large proportions of young patients, male patients and aggressive forms of the disease. Using North-Africa (Morocco, Algeria, Tunisia, Libya and Egypt) as an example, we document the magnitude and explore possible explanations for such patterns. Articles and reports published since the seventies were reviewed.

[Seroprevalence of toxoplasmosis in pregnant women in Annaba, Algeria].

Background: The aim of the study was to estimate the seroprevalence and risk factors of toxoplasmosis in pregnant women in the department of Annaba, Algeria.

Methods: We performed a cross-sectional study with analytical purposes. The study was collaboration between the laboratory of Parasitology-Mycology, Faculty of Medicine of Annaba and Parasite Biology Department at the Pasteur Institute of Algeria.

Automated detection of nosocomial infections: evaluation of different strategies in an intensive care unit 2000-2006.

The aim of this study was to evaluate seven different strategies for the automated detection of nosocomial infections (NIs) in an intensive care unit (ICU) by using different hospital information systems: microbiology database, antibiotic prescriptions, medico-administrative database, and textual hospital discharge summaries. The study involved 1,499 patients admitted to an ICU of the University Hospital of Lyon (France) between 2000 and 2006. The data were extracted from the microbiology laboratory information system, the clinical information system on the ward and the medico-administrative database.

[Use of the French medico-administrative database (PMSI) to detect nosocomial infections in the University hospital of Lyon].

Background: Surveillance is an effective element in the fight against nosocomial infections, but the monitoring methods are often cumbersome and time consuming. The detection of infection in computerized databases is a means to alleviate the workload of health care teams. The objective of this study was to evaluate the performance of using discharge summaries in medico-administrative databases (PMSI) for the identification of nosocomial infections in surgery, intensive care and obstetrics.
