[French general practitioners and electromagnetic fields].

Objective: To assess the perception of risk of general practitioners (GPs) about electromagnetic fields (EMF), their sources of information, as well as their patients' level of concern.

Methods: Six hundred French GPs were selected according to the quotas method. They were asked to answer 24 items via an electronic questionnaire using the Computer-Assisted Web Interviewing (CAWI) method.

[Is the clinical profile of women treated with tibolone similar to that of women receiving a classical estrogen-progestogen therapy? Data from a nationwide survey in France].

Objectives: To compare the pre-existing risk profiles for breast or endometrial cancer of menopaused women receiving tibolone or another hormone replacement therapy in France, with a view to examining the possibility of biases of selection of patients and of detection of these cancers in the Million Women Study.

Patients And Methods: Nationwide survey conducted in France among a representative sample of 153 gynaecologists. The particulars of the last two consulting menopaused women treated with tibolone (N = 306) and of the last two treated with a classical estrogen-progestogen therapy (N = 306) were collated then analysed.

[A new approach to arterial rigidity: ultrasonic tissue mode imaging].

Vascular stiffness is a major contributory factor of cardiovascular morbidity and mortality. Tissue Doppler imaging (TDI) could make it possible to evaluate vascular rigidity in a site by the measurement of the arterial wall velocity. The objective of this work is to validate the use of tissue Doppler imaging in the assessment of carotid rigidity.
