[Impact of an intervention on the practice of venous thromboprophylaxis recommendations in a geriatric setting.].

The practice of prevention of venous thromboembolic disease in hospitalized elderly patients does not comply with published recommendations, in 30% of cases. The objective of this study was to evaluate the impact of recalling the recommendations on the venous thromboprophylaxis.

Efficiency of fine-needle aspiration compared with other sampling techniques for laboratory diagnosis of Buruli ulcer disease.

In accordance with recent WHO recommendations, this study evaluates the sensitivities of PCR and microscopy for fine-needle aspiration (FNA) versus techniques involving swabs and punch biopsy specimens and suggests that FNA can replace punch biopsies for nonulcerative lesions and may serve as an alternative for ulcerative lesions in cases where scarred edges prevent the collection of swabs.
