[Grippe and pregnancy. Relation of birth weight to placenta weight].

The different results that have been published concerning the problem of the final outcome for patients who have had influenza during pregnancy reported in numerous works might be explained by differences in methodology used by the different authors. A study was carried out in the Haguenau Maternity Hospital (Bas-Rhin) when an epidemic of influenza occurred in 1972-173. The virological diagnosis was made by carrying out separate serological estimations on 1940 pregnant women.

[Sero-epidemiology of infections due to cytomegalovirus by indirect hemagglutination technic].

Applied to cytomegalovirus, the technique of indirect hemagglutination offers a good sensitivity and reliable specificity for serological testings. Improvements in the standardization are however still required. Sero-epidemiological studies performed in different groups of children and carried out with this method led to the following results: mother-child contagium, early infection in young infants, and influence of socio-economical and ethnical factors.
