Les données de surveillance disponibles ne permettent pas de suivre l'incidence des infections génitales à Chlamydia trachomatis(Ct). Leurs complications (infections génitales hautes, grossesses extra-utérines) pourraient être plus facilement repérables dans le Système national des données de santé (SNDS). Ceci nécessite de développer des algorithmes d'identification de ces complications.

Glow discharge optical emission spectrometry (GDOES) is a technique widely used for depth profile analysis but there are two significant limitations: samples must have planar surfaces and profile analysis generally cannot go beyond a depth of 100 µm. A new method of sample preparation has been developed to overcome both of these limitations, consisting of plastic deformation of the curved sample by pressing it until a planar surface is obtained. Furthermore, after profile analysis, the surface surrounding the glow‐discharged zone of the sample is ground to obtain a uniform layer levelled down to the bottom of the crater. Repeated grinding operations and profile analyses allow analysis of samples with practically unlimited thickness. An application of this method to determine the entity of the decarburized layer on a carbon steel rod sample is described in this paper. Copyright © 2001 John Wiley & Sons, Ltd.
