Since their introduction, genetic tests have been carefully considered, with special attention to the release of information about the test and test results, the confidentiality of genetic information, the request and its motivation, and the psychological impact of the test. Careful consideration is needed when family members at risk are asymptomatic children or adolescents. Cautious reflection is warranted on whether and under which conditions genetic testing should be performed.

T cells play a central role in the development of immune responses. Patients lacking T cells because of genetic defects such as DiGeorge or Nezelof syndromes and patients infected with the human immunodeficiency virus are highly susceptible to infections and cancers. The lack of adequate in vivo models of T cell neogenesis have hindered the development and clinical implementation of effective therapeutic modalities aimed at treating these and other clinically important maladies.

Pathologists and pediatric hematologist/ oncologists of the World Health Organization's Committee on Histiocytic/Reticulum Cell Proliferations and the Reclassification Working Group of the Histiocyte Society present a classification of the histiocytic disorders that primarily affect children. Nosology, based on the lineage of lesional cells and biological behavior, is related to the ontogeny of histiocytes (macrophages and dendritic cells of the immune system). Dendritic cell-related disorders of varied biological behavior are dominated by Langerhans cell histiocytosis, but separate secondary proliferations of dendritic cells must be differentiated.

We report two male sibs, born to non-consanguineous healthy parents, who showed arthrogryposis, cholestatic jaundice and tubular renal insufficiency. The liver biopsy of the first case showed scanty hypoplastic biliary ducts. This association, first reported by Lutz and Richner in 1973, is a distinct syndrome, characterized by intra-extrahepatic biliary hypoplasia, and described in McKusick's catalogue under the number 210550.
