[Multiple erythema migrans and facial nerve paralysis: clinical manifestations of early disseminated Lyme borreliosis]. / Multilokuläre Erythemata migrantia und Fazialisparese : Klinische Manifestationsformen der disseminierten Frühinfektion der Lyme-Borreliose.

Lyme borreliosis is a common vector-borne disease in Europe. The infection follows different stages with a broad variability of clinical symptoms and manifestations in different organs. A 49-year-old man presented with flu-like symptoms, facial nerve paralysis and multiple erythematous macular on his trunk and extremities. We diagnosed Lyme disease (stage II) with facial nerve paralysis and multiple erythema migrans. Intravenous ceftriaxone led to complete healing of hissymptoms within 2 weeks.

Estimated incidence of erythema migrans in five regions of France and ecological correlations with environmental characteristics.

BACKGROUND: While several studies conducted on Lyme borreliosis (LB) risk in the United States showed an association with environmental characteristics, most of European studies considered solely the effect of climate characteristics. OBJECTIVES: The aims of this study were to estimate incidence of erythema migrans (EM) in five regions of France and to analyze associations with several environmental characteristics of the place of residence. METHODS: LB surveillance networks of general practitioners (GPs) were set up for a period of 2 years in five regions of France. Participating GPs reported all patients with EM during the study period. Data were pooled according to a standardized EM case definition. For each area with a participating GP, age-standardized incidence rates and ratios were estimated. Associations with altitude, indicators of landscape composition, and indicators of landscape configuration were tested with multivariate Poisson regression. RESULTS: Standardized estimated incidence rates of EM per 10(5) person-years were 8.8 [95% confidence interval (CI)=7.9-9.7] in Aquitaine, 40.0 (95% CI 36.4-43.6) in Limousin, 76.0 (95% CI 72.9-79.1) in the three participating départements of Rhône-Alpes, 46.1 (95% CI 43.0-49.2) in Franche-Comté, and 87.7 (95% CI 84.6-90.8) in Alsace. In multivariate analysis, age-adjusted incidence rates increased with the altitude (p<0.0001) and decreased with forest patch density (p<0.0001). CONCLUSION: The marked variations in EM risk among the five regions were partly related to differences in landscape and environmental characteristics. The latter may point out potential risk areas and provide information for targeting preventive actions.
