    Notes: Summary Ribosomes isolated from fibroblasts, muscle tissues, and blood cells of a patient with congenital non-progressive myopathy were used for in vitro measurement of protein synthesis in a heterologous poly(U)-directed polyphenylalanine synthesis system. The activity of ribosomes obtained from the patient was 35% lower than that in normal controls.

    Notes: Abstract l-Selectin, a leukocyte surface glycoprotein involved in white blood cell extravasation, is rapidly down-regulated after leukocyte activation. We prospectively determined lymphocytel-selectin expression in freshly obtained cord blood samples of 98 neonates (gestational age 25–42 weeks). In eight infants with bacterial infection, the mean percentage ofl-selectinhigh lymphocytes was 32.5% (SD 20.1%), compared to 60.1% (SD 18.7%) in the control group (P〈0.01). A percentage ofl-selectinhigh lymphocytes of less than 42% had a sensitivity of 75% and a specificity of 82% in identifying infected newborns. Cord blood lymphocytel-selectin expression was independent of gestational age, birth weight, umbilical artery pH, hematocrit, white blood cell count, absolute neutrophil count, C-reactive protein level, or maternal fever before delivery while there was a weak correlation with the newborn's immature/total ratio and platelet count. To our knowledge, this is the first report demonstrating downregulation of human lymphocytel-selectin expression following activation of the immune system in vivo.

    Notes: Summary Ten new cases of accessory bisatellited marker chromosomes examined in different laboratories are reported. As a basis for genetic counselling in the context of prenatal diagnosis a cytogenetic categorization of such marker chromosomes is proposed and an estimation of the genetic risk associated with each category is carried out. The results are as follows: 1. There is no increased risk for offspring with abnormal phenotype born to a healthy carrier of an accessory bisatellited marker chromosome with either a single or two closely adjacent C-bands (Category AI or AII). 2. The unbiased sample of cases with de novo accessory bisatellited marker chromosomes of categories AI and AII is too small to allow a satisfactory estimation of the actual risk that, in case of such a prenatal finding, the foetus may not show a normal phenotype as a consequence of the marker chromosome. There is, however, evidence that this risk may be lower than 10%. 3. Accessory bisatellited marker chromosomes showing a discrete pattern of G- or R-bands situated between two distant C-bands (Category AIII) usually indicate a chromosomal imbalance giving rise to an abnormal phenotype. Mosaic carriers of such dicentric marker chromosomes may, however, present a normal phenotype.

    Description / Table of Contents: Summary We report on a female preterm infant of 29 weeks' gestation with severe hydrops fetalis who died 3 days post natum as a result of disseminated intravascular coagulation. Autopsy findings included anasarca, bilateral pleural effusions, ascites and hepatosplenomegaly as well as multiple, up to pinhead sized, white granulomas on the surface of liver, spleen and lungs. Microscopy revealed storage macrophages of the reticuloendothelial system, especially in liver, spleen and bone marrow, the lymphatic organs, the salivary glands, the thyroid gland and the suprarenal medulla. Cerebrum, heart, kidneys, intestines and placenta were not afflicted. Atrophy of the lymphatic compartments in the spleen, lymph nodes and thymus, as well as disorder of the liver texture, are presumably a secondary result. The diagnosis of Farber's disease was established biochemically by the demonstration of ceramide depositions in the spleen, and in fibroblast cultures in situ by the accumulation of ceramide released from loaded radioactive glucosylceramide. Ultrastructurally, corresponding storage lysosomes were found in macrophages. To our knowledge this is the first account of Farber's disease in a preterm infant with hydrops fetalis.
    Notes: Zusammenfassung Wir berichten von einem weiblichen Frühgeborenen der 29. Schwangerschaftswoche mit schwerem Hydrops fetalis, das 3 Tage nach Geburt an den Folgen einer disseminierten intravasalen Gerinnung (DIC) verstarb. Autoptisch imponierten Anasarka, bilaterale Pleuraergüsse, Aszites und eine Hepatosplenomegalie, wobei makroskopisch stecknadelkopfgroße weiße Granulome an der Oberfläche von Leber, Milz und Lungen auffielen. Lichtmikroskopisch fanden sich Speichermakrophagen des RHS besonders in Leber, Milz, Knochenmark, den lymphatischen Organen, den Kopfspeicheldrüsen, der Schilddrüse und im Nebennierenmark. Großhirn, Herz, Nieren, Intestinum und Plazenta waren nicht betroffen. Eine Atrophie der lymphatischen Kompartimente in Milz, Lymphknoten und Thymus sowie ein schwerer Leberschaden sind vermutlich sekundäre Folgen der Erkrankung. Die Diagnose M. Farber wurde biochemisch durch den Nachweis von Ceramidablagerungen in der Milz gesichert wie auch durch die Anreicherung von radioaktivem Ceramid in Fibroblastenkulturen nach Zusatz von markiertem Glucosylceramid. Ultrastrukturell wurden entsprechende Speicherorganellen in Histiozyten wie auch in Endothelzellen und Gallengangsepithelien der Leber gefunden. Unseres Wissens ist dies die erste Beschreibung eines M. Farber bei einem Frühgeborenen mit Hydrops fetalis.
