Four human cases of localized cutaneous leishmaniasis caused by Leishmania naiffi are reported. Two of the cases were infected in French Guiana, one in French Guiana or Martinique, and the other in Ecuador or Peru. The geographical distribution of L. naiffi is clearly larger than that initially reported. Three zymodemes were represented by the four(More)
BACKGROUND Sublingual immunotherapy (SLIT) is a relatively new form of treatment for type I allergies and a good safety profile is rapidly being established. Evidence on the efficacy of SLIT is increasing, and the present study provides further supportive data. We describe the results of treatment with a SLIT vaccine formulated with a range of allergen(More)
It has been proposed that polymorphisms of the Merozoite Surface Protein 1 and 2 (MSP1 and MSP2) and the Glutamate Rich Protein (GLURP) genes can be considered as genetic markers for the genotyping of field populations of Plasmodium falciparum. During a field study on in vivo drug resistance against chloroquine, sulphadoxine/pyrimethamine (S/P) and(More)
In order to determine the influence of rheumatoid factor in serum specimens on the specificity of an immunochromatographic test for the detection of antibodies against dengue virus, 50 clinical specimens containing rheumatoid factor were evaluated for cross reactivity with a commercially available assay. While specificity for the detection of immunoglobulin(More)
The in vitro growth of Plasmodium falciparum was reduced by 35 and 43% through high concentrations (5 mmole/liter) of magnesium in RPMI medium and magnesium-free medium, respectively, after 48 hr, whereas no significant inhibition could be observed under these conditions after 24 hr cultivation in the respective medium. Levels of magnesium between 0.5 and 3(More)

Hepatitis A and B continue to represent a risk for travelers. Those traveling to tropical countries are usually aware of this risk, while those visiting a Mediterranean country often are not. This investigation presents a destination-related risk assessment and vaccination recommendations for travellers, on the basis of incidences and prevalences of(More)
BACKGROUND A short-term immunotherapy vaccine for the treatment of pollen allergy has been developed utilising L-tyrosine adsorbed allergoids. The reduced number of injections could provide advantages over long-term therapy schedules. This would improve compliance and support application of specific immunotherapy (SIT) to a greater extent. We report a(More)
The history, clinical features, laboratory tests and admission circumstances were analysed retrospectively in 14 patients, aged 60 to 87 years, who were found to have a chronic subdural haematoma. Typical clinical features consisted of dominant psychiatric disorders, slow progression and frequently only traces of neurological signs. In only four patients(More)
