    Description / Table of Contents: Zusammenfassung Bei 17 Patienten mit angeborenen Immunmangelkrankheiten wurden die T- und B-Lymphocyten quantitativ untersucht. Gleichzeitig wurden zur funktionellen Beurteilung der beiden Zellpopulationen die Antwort auf Stimulation mittels Phytohämagglutinin und die Serumkonzentration der Immunglobuline untersucht. In einer vorbereitenden Studie wurde die Zuverlässigkeit der verwendeten Methoden kontrolliert; dafür wurden die Zellmarker (Rosettenbildung mit Schafserythrocyten für T-Zellen, Membranimmunfluorescenz für B-Zellen) anhand von zwei unterschiedlichen Lymphoidzellpopulationen genauer definiert: als nahezu reine T-Zellen wurden frisch zubereitete Suspensionen aus Thymusbiopsien von drei jungen Kindern verwendet, als B-zellreiche Präparate die isolierten Lymphocyten von drei Patienten mit chronisch lymphatischer Leukämie. Zur Klassifizierung der angeborenen Immunmangelsyndrome wurden die Vorschläge eines Expertenkomitees der Weltgesundheitsorganisation befolgt [12, 13]: 2 Patienten mit Agammaglobulinämie, 5 mit variablem Immunmangel, 4 mit Ataxia telcangiectatica, 3 mit schwerem kombiniertem Immunmangel und 3 mit Wiskott-Aldrich-Syndrom konnten ausführlich untersucht werden (Ergebnisse s. Tabelle 2). Die kritische Beurteilung der Resultate trägt zum besseren Verständnis der normalen Differenzierung lymphoider Zellen und der zur Immunmangelkrankheit führenden Störungen bei (vgl. dazu Abb. 1).
    Notes: Summary The T- and B-lymphocytes of 17 patients with immunodeficiency diseases were determined quantitatively. Simultaneously, their functional behavior, i.e. the response to stimulation by phytohemagglutinin and the immunoglobulin levels were studied. In a preliminary study devised to check the accuracy of the methods used, the cell markers (rosette formation with sheep erythrocytes for T-cells and membrane immunofluorescence for B-cells) were defined by means of two different lymphoid cell populations: as nearly pure T-cells the fresh suspensions prepared from thymic biopsies of 3 young children were used, as B-cell rich preparations the isolated lymphocytes of 3 patients with chronic lymphatic leukemia. Immunodeficiency syndromes were classified according to the recommendations of a World Health Organization expert committee [12, 13]: 2 patients with agammaglobulinemia, 5 with variable immunodeficiency, 4 with ataxia teleangiectatica, 3 with severe combined immunodeficiency and 3 with Wiskott-Aldrich syndrome were extensively studied (Table 2). The results are relevant for the better understanding of normal differentiation and its disturbances leading to the different deficiency syndromes (cf. Fig. 1).

    Notes: abstract Four months after termination of successful chemotherapy for epipharyngeal B-non-Hodgkin lymphoma, an enlarging anterior mediastinal mass was discovered in a 15-year-old boy. There was no other suspicion of tumour recurrence. A simple thymic rebound was likely and a conservative management was chosen. Follow up for more than 12 months was uneventful. The frequency of thymic hyperplasia after termination of chemotherapy is discussed. It is a benign immunological rebound phenomenon and does not require operative intervention.

    Notes: Abstract Body measurements were taken and the prevalence of major malformations and of 57 minor anomalies was determined in 106 children with malignant disease, in 81 of their sibs, and in 106 control subjects matched to the patients according to sex, age and ethnic origin. Leukaemic children had a significantly smaller head circumference than the corresponding control children, but no significant differences in height, anthropometric and syndromologic indices were found. No differences were observed in the frequency of associated major malformations including renal malformations detectable by sonography. The prevalence of minor anomalies was significantly higher in the patients with malignant disease and their sibs than in the control children: 69.2% of the patients, 63.0% of the sibs and 34.6% of the control subjects had at least one minor anomaly. When two and more minor anomalies were considered, the prevalence figures were 36.5%, 29.6% and 12.5%, respectively. Among the single minor anomalies only the Sydney line was significantly more frequent in patients with solid tumours. No specific association of an individual dysplasia or a pattern of minor anomalies with a given tumour could be established.

    Notes: Summary 3 families with congenital inactivity of the enzyme adenosine deaminase (ADA) observed in this hospital, were reinvestigated with an attempt at correlating the phenotypes of different probands with their isoprotein pattern. The latter was visualized after electrophoretic separation on cellulose acetate membranes (CAF) by a stain incorporated in agar gel. Isoprotein patterns and total enzyme activity were estimated by simple inspection and by scanning photometry. The results of both methods were unequivocal and concordant. In the 3 families 48 members were investigated. ADA activity was normal in 28 (normal homozygotes), decreased to about one half of the normal activity in 19 (heterozygote individuals), and not detectable in one person (deficient homozygote,—this individual died of severe combined immunodeficiency = SCID). Of the same people 46 showed the phenotype ADA-1, one ADA-2-1, and the phenotype of the girl lacking ADA activity could not be determined. 2 of the 6 obligatory heterozygous carriers (parents) exhibited ADA activity in the normal range. This is in keeping with the demonstration of geneticists that heterozygotes may be detected with a reliability of 90 to 95%.—Additional anomalies in the genetic transmission of phenotypic expression as described by other authors were not detected in these 3 families. Advantages and drawbacks of the electrophoretic method used in this study compared with the purely biochemical photometric method are discussed.

    Description / Table of Contents: Zusammenfassung Ein Zusammenhang zwischen dem Enzym Adenosindeaminase (ADA) und Immunfunktionen ist gesichert: Patienten mit kongenitalem Mangel der ADA weisen einen schweren kombinierten Immundefekt auf. Bei Patienten, die mit immunsuppressiven Mitteln behandelt wurden, fanden wir im Gegenteil erhöhte ADA-Enzymaktivität. Zu den bisherigen kontroversen Befunden über ADA bei akuten Leukämien trägt unser Material folgendes bei: Kinder mit akuter lymphatischer Leukämie (ALL) und akuter myeloischer Leukämie (AML) in Remission weisen normale bis erhöhte ADA-Aktivität auf, solange sie unter zytostatischer Therapie stehen. Nach Heilung der Leukämie (d. h. in Dauerremission ohne Therapie) normalisieren sich die ADA-Aktivitäten. Eine Heterogeneität innerhalb der Leukämie-Gruppen ist aber nicht ausgeschlossen. — Die zelluläre Immundefizienz bei akuter Leukämie erklärt sich aus diesen Befunden nicht.
    Notes: Summary A causal relation between the enzyme, adenosine deaminase (ADA), and immune dysfunction is well known: patients with congenital inactivity of ADA invariably suffer of severe combined immunodeficiency. In contrast, we found in patients treated with immunosuppressive drugs increased ADA enzyme activity. Previous findings on ADA activity in acute leukemias are until now controversial. We found normal to increased ADA activity in children with acute lymphatic leukemia (ALL) and acute myeloid leukemia (AML) in remission as long as they were treated with cytostatic drugs. In the group of cured leukemics (in continuous remission after suspension of the therapeutic regimen) the ADA activities were normal. These findings do not exclude a heterogeneity within the leukemia group. They do not explain the signs of cellular immunodeficiencies well known in patients with acute leukemias.

    Notes: Abstract Background:Information on long-term follow-up of children andadolescents treated for intracerebral germ-cell tumour is scant. We report onthe results of a small series of patients treated at a single institution. Patients and methods:Hospital records from 15 patients treatedbetween 1980 and 1998 were reviewed. An attempt was made to correlate sequelaeto tumour location and treatment modalities. Results:This cohort constitutes 5.5% of all brain tumoursdiagnosed at our institution. Histology: 10 germinomas, 2 benign teratomas,2 malignant teratomas, and one mixed germ-cell tumour. Overall survival was87%, with a mean follow-up time of 7 years and 8 months. The majorityof patients have long-term sequelae involving one or several organ systems.In 66% endocrine, in 47% ophthalmologic, in 60%neuropsychological defects were observed. Endocrine and ophthalmologicsequelae show a correlation to tumour location. Neuropsychological long-termabnormalities are frequent and are associated with cranial irradiation inparticular at young age, but less with tumour location, irradiation dose orsurgery. Conclusions:Our preliminary data suggest that today intracerebralgerminomas and mature teratomas have a good prognosis even when a relapseoccurs. The outcome for mixed germ-cell tumours and malignant teratomas isless favourable. Although long-term sequelae are present in the majority ofpatients, there is some evidence that patients treated after 1990 suffer fewersevere long-term defects, thereby indicating that recent treatment protocolsmay result in a reduction of sequelae.
