    Notes: Abstract We describe a 30-year-old acute myelomonocytic leukemia patient with abnormal bone marrow eosinophils (AML FAB subtype M4Eo) with extensive extramedullary involvement and, in the absence of an aberration involving chromosome 16, clonal trisomy 21 in the leukemic blast cells.

    Description / Table of Contents: Summary We report on a 6-year-old Romanian girl with recently diagnosed hyper-IgD-syndrome. The leading symptome of this rare disease are periodic pyrexia, joint involvements (arthralgias/arthritis) and swollen lymph nodes. A permanent increase of α1-acid glycoprotein fucosylation indicates persisting inflammation. Most important in differential diagnosis in familial Mediterranean fever. Therapy is merely supportive as yet, the long-term outlook seems good despite duration of the illness. Conclusion: the hyper-IgD-syndrome must be considered in cases of otherwise unexplained periodic fever.
    Notes: Zusammenfassung Das Auftreten von periodischem Fieber bei einem Kind stellt oft hohe diagnostische Anforderungen, und nicht selten erfordert die Erkennung der Ursache eine längere Zeit. Es wird ein jetzt 6jähriges Mädchen beschrieben bei dem erst nach 4jähriger Krankheitsdauer die Diagnose eines Hyper-IgD-Syndroms gestellt wurde. Diese seltene Erkrankung, deren Leitsymptom periodisches Fieber von 3 bis 5 Tagen Dauer, Arthralgien bzw. nicht erosive Arthritiden und submandibuläre Lymphknotenschwellungen sind, zeigt auch in Remissionsphasen eine Erhöhung der Fucosylation von sauren α1-Glykoprotein, was auf eine persistierende Entzündung hinweist. Differentialdiagnostisch muß vor allem das familiäre Mittelmeerfieber in Betracht gezogen werden. Die Therapie ist supportiv, die Prognose gut, obwohl die Erkrankung lebenslang bestehen bleibt. Schlußfolgerung: Bei periodischem Fieber unklarer Ursache muß auch ein Hyper-IgD-Syndrom in die differentialdiagnostischen Überlegungen einbezogen werden.

    Notes: Summary A case of acute lymphoblastic leukaemia of null cell type in infancy showed the specific reciprocal translocation t(4; 11) (q21; q23) reported 16 times so far in the world literature. The proportions of abnormal and normal metaphases throughout the course of the illness correlated well with the clinical picture, but even during the short term remission metaphases expressing the translocation were still identifiable in appreciable numbers. Comparison between cytogenetic analyses of cultured and native bone marrow, PHA-stimulated and non-stimulated peripheral blood demonstrated the gradual conquest of the periphery by the abnormal clone. The importance of chromosomal changes and their interpretation for diagnosis, classification and prognostic judgment in haemotologic neoplasms is discussed in the light of the reported case.

    Notes: Abstract The proportions of Gγ and Aγ globins in hemoglobin F were determined in fetuses around the 20th week of gestation, newborns, and children 3 weeks to 5 months of age. In the last group, the Gγ/Gγ + Aγ ratio decreased continously; there was a good correlation between the decline of Gγ with respect to total γ and the decline of Hb F (r=0.88). In contrast, there was virtually no difference in the γ globin composition of Hb F between the fetuses and the newborns, i.e. in late pregnancy, the decrease in the synthesis of both γ globins appears to be proportionate. The Gγ and Aγ globin genes may be inactivated in a sigmoidal fashion with time, thus producing a Gγ/Gγ + Aγ ratio which at first changes only slightly and then declines linearily.

    Notes: Abstract We have analyzed the phospholipid composition of various organs of patients with the cerebro-hepato-renal (Zellweger) syndrome. The phospholipid composition of tissues from controls and patients was very similar except for their plasmalogen contents. In controls about 50% of the phosphatidylethanolamine fraction of brain, heart, kidney and skeletal muscle and about 10% of that fraction in control liver tissue was found to consist of plasmalogen. In control heart muscle, but not in other control tissues about 25% of the phosphatidylcholine fraction consist of plasmalogens. In contrast, plasmalogens were nearly absent in the corresponding tissues of Zellweger patients. The amount of phosphatidylethanolamine plasmalogens in both erythrocytes and fibroblasts of Zellweger patients is lowered significantly compared to control erythrocytes and control fibroblasts respectively, although this reduction is not as dramatic as in brain, heart, kidney, skeletal muscle and liver of patients. Phosphatidylcholine-plasmalogens are only present in low amounts in both controls, heterozygotes and patients. In recent years considerable evidence has accumulated to show that peroxisomes are involved in cellular lipid metabolism. Notably, the key enzymes of ether lipid (plasmalogen) biosynthesis in rodents were recently found to be located in peroxisomes. Since electronmicroscopic studies have shown that peroxisomes are absent in liver and kidney of patients with the cerebro-hepato-renal syndrome, our results suggest that an inability to integrate these key enzymes in a functional peroxisome leads to a severe disturbance in plasmalogen biosynthesis. We propose that the multiple clinical and biochemical defects in Zellweger patients are secondary to a deficiency in peroxisomal function.
