Completion of the nucleotide sequence of the central region of Tn5 confirms the presence of three resistance genes.

The DNA sequence of the region located downstream from the kanamycin resistance gene of Tn5 up to the right inverted repeat IS50R has been determined. This completes the determination of the sequence of Tn5 which is 5818 bp long. The 2.7 Kb central region contains three resistance genes: the kanamycin-neomycin resistance gene, a gene coding for resistance to CL990 an antimitotic-antibiotic compound of the bleomycin family and a third gene that confers streptomycin resistance in some bacterial species but is cryptic in E. coli. A Tn5* mutant able to express streptomycin resistance in E. coli was isolated. With this mutant, it was demonstrated that in E. coli the expression of the three resistance genes is coordinated in a single operon.

[Thoracic opacity in a newborn infant disclosing an adenomatoid cyst of the lung. Radio-echographic case].

In a preterm infant (28 week gestation), the chest film performed at 1 hour of life because of mild respiratory insufficiency showed a massive opacity of the right hemithorax. Congenital cystic adenomatoid malformation was suspected on the basis of ultrasonographic findings of multiple cysts. It was confirmed by further X ray examination and pathologic findings. This unusual case shows the ultrasonographic pattern and X ray evolution of this rare malformation.

[Distinctive nature of mountain sport maxillo-facial injuries (author's transl)].

Mountain sports were the cause of 400 facial injuries treated in he Maxillo-facial Surgical Unit in Grenoble over a period of 5 years. Deltaplane injuries are becoming more frequent. Isolated facial injuries represent 57 p. cent of the cases treated. The various types of lesions encountered are described, and the distinction drawn between those treated as emergencies, and those for which urgent treatment could be delayed.
