[Sexually transmitted diseases, AIDS and prostitution: a case study in Guinea-Conakry]. / Maladies sexuellement transmissibles, sida et prostitution: une étude de cas en Guinée-Conakry.

In Africa, many public health interventions related to the fight against HIV/AIDS are aimed at women commercial sex workers. The practices of sexual labour and prostitution are not universal, and considering them within their specific cultural context is vital to understanding these women's needs and the prevention of HIV/AIDS. An exploratory qualitative study inspired by well-rooted theory was conducted with 14 women working within formally renowned prostitution sites in Guinea-Conakry. It aimed at identifying the context and general preoccupations of these women, within which are embedded sanitary concerns. The study showed that their sexual behaviours are mostly influenced by collective, relational and economic aspects which are in turn evaluated by the women within the framework of their continuous and changing life cycle.

Analysis of amphoteric surfactants of the alkylaminopropylglycine type by gas chromatography.

A procedure was developed for gas chromatographic analysis of glycine-type amphoteric surfactants. The commercial samples contained N-alkylaminopropylglycines, N-alkylamines and N-alkylaminopropylamines. Some di- and triacids were also detected. The method proposed allows a good separation according to both the carbon number and the chemical function.
