[Molecular diagnosis of a fatal primary amoebic meningoencephalitis in Guadeloupe (French West Indies)]. / Diagnostic moléculaire d'une méningoencéphalite amibienne primitive à l'occasion d'un cas fatal en Guadeloupe.

We report the first case of primary amoebic meningoencephalitis in a 9-year-old boy in Guadeloupe. The outcome was rapidly fatal in 7 days. The patient presumably acquired the infection by swimming and diving in a basin supplied by natural thermal water 1 week before onset of the disease. The possibility of a free-living amoeba infection was suspected both on the negativity of all bacterial and viral initial tests and on the observation of peculiar cells in stained cerebrospinal fluid samples. Although the amoeba was not isolated, Naegleria fowleri could be identified by polymerase chain reaction with specific primers on DNA extracted from frozen cerebrospinal fluid samples. Furthermore, as the internal transcribed spacer (ITS1) region of DNA is variable in length between the different strains of N. fowleri, sequencing of the amplified ITS1 demonstrated that the responsible N. fowleri strain belongs to a common genotype present in the American and European continent.

Dermatoses associated with travel to Burkina Faso and diagnosed by means of teledermatology.

BACKGROUND: The pattern of dermatoses occurring in travellers to tropical areas is poorly documented. OBJECTIVES: To diagnose skin diseases in travellers to Burkina Faso by means of teledermatology; to assess the educational value of teledermatology for the local general practitioner (GP). METHODS: Patients (Westerners and Burkinabese nationals) were included in the study if they presented with a cutaneous disease to the GP based in Ouagadougou, Burkina Faso. Images of the skin lesions were acquired with a point-and-shoot digital camera and sent via the Internet, together with the clinical history. Diagnostic concordance between dermatologists in France and the GP in Ouagadougou was analysed as a simple proportion of agreement and 95% confidence interval. RESULTS: One hundred and twenty-four patients (M/F ratio 1.17; 80.6% Westerners) were included in the study. One hundred and thirty dermatoses were identified: 73 (56%) were of infectious origin, and 19 (15%) were related to eczematous dermatitis. The skin infections were mainly due to bacteria (18%), fungi (14%) or arthropods (13%). Parasitic dermatoses were observed only in Burkinabese nationals. Among Westerners, fungal dermatoses were observed only in long-term residents. The diagnostic agreement between the local GP and the remote dermatologists was 49% overall (95% confidence interval 41-58). Agreement between the GP and the dermatologists on the dermatological category improved significantly over time (P<0.05). CONCLUSIONS: Telemedecine can improve the management of cutaneous diseases among Western travellers. Most dermatoses observed in Western travellers to Burkina Faso are of infectious origin. Teledermatology has educational value for local GPs.
