[A syndrome of congenital diabetes with disordered epiphyseal growth with autosomal recessive inheritance (author's transl)].

A child is described with insulin dependent diabetes of neonatal onset and a disorder of endochondral growth. Radiological and histological bone appearances differ from those observed in other types of chondrodysplasia. The association of diabetes and chondrodysplasia is not likely to occur by chance but is probably a genuine clinical entity.

[The prognostic value of factor XIII in Schönlein-Henoch purpura in childhood (author's transl)].

In a prospective study of 19 cases of Schönlein-Henoch purpura, the factor XIII level was compared with 32 normal controls. The study demonstrates that factor XIII levels are of value both in making the diagnosis of Schönlein-Henoch purpura and predicting the outcome. If the factor XIII level is greater than 80% the diagnosis of Schönlein-Henoch purpura is unlikely and if factor XIII level is less than 60% of normal, the risk of complications is high.

[Partial trisomy 18 (pter leads to q122) of maternal origin (author's transl)].

Partial trisomy of chromosome 18 (pter leads to q122) due to a maternal t(9;18) is described. The proband's phenotype which includes many features of Edward's syndrome, is compared to other cases of partial trisomy 18 already reported.
