We report a 18 weeks old fetus with the typical limb reduction anomalies of SC phocomelia syndrome, associated with exencephaly and unilateral anophthalmia, a feature previously reported in only 2 cases of severe Roberts syndrome. This observation brings another argument for lumping both diseases in a unique Roberts-SC phocomelia syndrome. Diagnosis was settled by the observation of premature centromeric splitting.
The Coffin-Lowry syndrome is an inherited syndrome of mental retardation, characteristic facies and skeletal anomalies. The occurrence of severe manifestations in males, with no instance of male-to-male transmission, suggests an X-linked inheritance. The paper describes seven families from five European Centers.
We report two children with a common pattern of birth defects. Both have very sparse, curly hair, nystagmus and mental retardation. The first one has Noonan syndrome habitus associated with keratosis plantaris and nystagmus; the second one has a slightly Noonan-like face, macrocephaly, keratosis pilaris, and hypertrophic cardiomyopathy. They represent the extreme of a spectrum of congenital defects recently reported independently as CFC syndrome by Reynolds and as "Noonan-like short stature syndrome with sparse hair" by Baraitser and Patton. The clinical features are reviewed and the autonomy of the syndrome with regards to Noonan syndrome, is disputed, since every sign seems to occur independently in Noonan syndrome. The father of the second case probably has a minor syndrome expression, pointing to probable autosomal dominant inheritance.
We report a family in which Opitz-Frias G syndrome is expressed across 4 generations. The propositus displays hypertelorism, low grade hypospadias, cleft palate and lips and cleft larynx, making the diagnosis of G syndrome very likely. A cousin of his mother discloses similar clefts, vulviform hypospadias, anal imperforation and mental retardation. His clinical appearance fits perfectly the diagnosis of BBB syndrome. A nephew shows ambiguous genitalia and hypertelorism. Authors suggest the lumping of the BBB and the G syndrome.

We report about two sibs showing a common pattern of birth defects, with a pedigree suggestive of autosomal recessive heredity. The main features are intrauterine growth failure with very low birthweight; disproportionate dwarfism with predominantly distal shortening of limbs; small cubitally inclined clenched hands; microcephaly with Seckel-like facies and delayed psychomotor development. X-ray findings include metaphyseal flare, V-shaped femoral metaphyses and bowing of forearms. Primordial microcephalic osteodysplastic dwarfism Type II is discussed. Metabolic and nutritional data are presented and discussed.
We report a case of Nager acrofacial dysostosis, whose clinical examination disclosed some undescribed features, as a contribution to a better delineation of this syndrome. Previously unreported features include lobulated tongue, cleft lip and mental retardation. Fetal alcohol syndrome is discussed. We propose to reunificate Richieri-Costa syndrome and Nager syndrome.
A slightly dysmorphic and mentally defective child with mosaic monosomy 22 is reported. Chromosome 22 is absent in 10.5% of lymphocytes and 8.3% of fibroblasts. This is the second case report of that kind.

Animal experiments and clinical data indicate that prolactin (PRL) induces hyperinsulinemia and even diabetes. The effects of PRL on carbohydrate metabolism may be explained by at least two different mechanisms. Either PRL induces an insulin resistance at the peripheral tissue level, or PRL has a direct cytotropic effect on the pancreatic islets. Obviously, both mechanisms inducing hyperinsulinemia may coexist. We report here immunocytochemical evidence that PRL is localized in the endocrine pancreas of the normal adult rat. More precisely, the immunoreactive PRL is distributed in the cytoplasm of insulin-secreting B cells. These findings support a direct action of PRL on the endocrine pancreas.

A newborn boy is described with semilobar holoprosencephaly, cebocephaly with single nostril, median pseudocleft of upper lip, postaxial polydactyly, hypogenitalism, Hischsprung's disease and survival till the age of 13 weeks. Chromosomal analysis on lymphocytes was normal. Up to now, three other patients with this malformation complex have been described. Together with the present patient, they are apparently the first examples of a new malformation syndrome.
