Incidence of central nervous system tumors in Gironde, France.

The incidence of CNS tumors is subject to geographical and temporal variations which are poorly understood. The incidence of these tumors was studied in Gironde, a department of southwestern France with 1,058,911 inhabitants older than 16 years. We recorded any malignant or benign central nervous system (CNS) tumor diagnosed between May 1999 and April 2001 in adults living in Gironde.

Tuberculosis is a highly contagious infectious disease in recrudescence whose epidemiologic monitoring is reinforced by molecular biology. In this context, we were particularly interested in the cases of tuberculosis of French West Indies and French Guiana (FWI-FG). This study covered a period of two years (1997 and 1998) and focused on the demographical and epidemiological characteristics of the cases diagnosed by an analysis of their genotypes.

Background: Over the past few years, epidemiologic surveys of tuberculosis have been strengthened by new biologic technology, in particularly using RFLP (Restriction Fragment Length Polymorphism). This technique, which identifies Mycobacterium tuberculosis patterns, has allowed to study thoroughly tuberculosis bacilli transmission and pathogenesis. First applied on tuberculosis epidemics in at risk groups, RFLP has now an interest in the epidemiologic molecular survey of urbans populations.
