Evaluation of the Performance of Rapid Diagnostic Tests for Malaria Diagnosis and Mapping of Different Species in Mali.

Background: The first-line diagnosis of malaria in Mali is based on the use of rapid diagnostic tests (RDT) that detect the Histidin Rich Protein 2 (HRP2) antigen specific to . Our study, based on a real-time polymerase chain reaction (qPCR) gold standard, aimed to describe the distribution of the species in each administrative region of Mali and to assess the performance of RDTs.

Methods: We randomly selected 150 malaria-negative and up to 30 malaria-positive RDTs in 41 sites distributed in 9 regions of Mali.

Schistosomiasis and Recurrent Arthritis: A Systematic Review of the Literature.

Background: Schistosomiasis is an endemic parasitic infection found in many tropical countries and is highly prevalent in sub-Saharan Africa. It can follow different and atypical clinical patterns. In these unusual cases, diagnosis may be difficult, as symptoms are unspecific.

[Burkitt's lymphoma-Epstein-Barr virus association in western Algeria. Clinical, cytological and serological aspects apropos of 34 pediatric cases].

Burkitt's lymphoma (BL) and naso-pharyngeal carcinoma (NPC) are tumors generally believed to be associated with Epstein-Barr virus (EBV). Algerian population could be considered at high risk for BL-EBV association. In a series of 34 BL patients observed by us between 1982 and 1984 characteristics were: 70% of children were under 5 years age, abdominal location in 90% of cases (n = 30), 13% only isolated, massive tumor burden (70% stage III after Murphy, 30% stage IV after Murphy and Duque-Hammershaimb), EBV serology titers above or equal to 640 in 60% of cases (anti-EBNA and anti-VCA) and 50% (anti-EA) respectively, presence of EBNA antigen in tumor cells found in 63% of cases, no complete correlation between serology positivity and EBNA presence.
