[Bone maturation in the fetus and newborn infant].

On the basis of a study of X-ray films of the lower limbs of 994 babies (included 245 hypotrophics) a "bone age" scale of the fetus between 28 and 42 weeks of gestation has been established. The Acheson's method has been used and the bone age determined by addition of notes given to different evolutive phases of the first five ossification centers of the ankle and the knee. To more practical purpose, the results of boys and girls have been joined, although the bone age is in advance among the girls and a theorical scale established with the 10th, 50th and 90th percentiles curves.

[Double venoma (varicosity) of the neck in an 8 year old child (author's transl)].

Venous ectasia in the neck, can for esthetic reasons, justify radical surgical treatment. But as it is a benign condition, the decision to operate also depends on the topography of the ectasia. The authors present the case of a double jugular localization, internal and external, explored by the techniques of direct and retrograde phlebography.
