[Increase in the percentage of female authors in the international psychiatric literature since 1970]. / Toename van het percentage vrouwelijke auteurs in de internationale psychiatrische vakliteratuur sinds 1970.

BACKGROUND: The participation of women in medicine and psychiatry is increasing. AIM: To find out whether this trend is also reflected in the international psychiatric literature. METHOD: We took steps to discover the gender of the first and the last author as listed below the title of 290 articles sampled at random from three leading psychiatric journals published between 1970 and 2007. results Women turned out to be underrepresented as the first or last author of these psychiatric articles; this conclusion was also found to apply to the first and last authors who were medical authors. Whereas the proportion of female first authors had increased significantly since 1970 and had reached almost 50% in 2007, there had been no such increase as far as last authors were concerned. CONCLUSION: In the psychiatric literature studied, the proportion of female first authors rose to almost 50%.

[Change test with DHEA-S in vivo and in vitro. Hypotrophy and utero-placental blood flow (author's transl)]. / Test de charge au DHEA-S in vivo et in vitro. Hypotrophie et débit sanguin utéroplacentaire.

Using the method of Cedard and al., we perfused 18 placentas of women in which DHEA-S loading test has been performed during pregnancy. For each placenta, we measured the increase of estrogens in the perfusate (E1 + E2) 15 minutes after the injection of 10 mg of DHEA-S, and we calculated the half-life of the precursor in the system in well-standardized conditions. The comparison between: 1. Placentas of small for date babies and normal ones. 2. The increase of estrogens and the half-life of DHEA-S measured during pregnancy on the one hand and the same data obtained from the perfusion on the other, leads us to conclude that the capacity of the placenta to metabolize DHEA-S into estrogens is not diminished in small-for-date babies. The factor which modifies the response of the DHEA-S loading test in poor intrauterine growth seems to be due to a reduction of utero-placental blood flow.
