[Mosaic trisomy 14 due to an iso dicentric chromosome (author's transl)].

Mosaic trisomy 14 due to a de novo formation of an iso dicentric chromosome 14 was observed in a male negro infant who died at the age of one week. Together with three previous reports in the literature of mosaic trisomy 14, this observation allows the delineation of a syndrome characterized by intrauterine growth retardation ; craniofacial dysmorphism with frontal bossing ; hypertelorism ; microretrognathia, small, lowset, abnormally folded ears ; a translucent film over the eyes ; and congenital heart disease.

[The average degree of parasitosis, a criterion for evaluation of the geohelminthic contamination of a population, and for application of santiary measures].

The severity of ascaridiasis in a region depends first of all on the degree of pollution by ascaris ova of the environemtn and consquently on the per diem output of ascaris ova in the stools. Therefore, the importance of ascaridiasis as an endemic disease, depends of course upon the number of positive cases, their prevalence, but still more, it depends upon the intensity of the infection of the diseased population (global parasitic discharge). Practically, this concept of global parasitic discharge is expressed by the number of ascaris ova expelled per gram and per day by a sample of the considered population.
