    Notes: Summary We examined 56 patients with latent or clinically manifest hypothyroidism and 18 patients with acute athyreosis as a control group. We were especially interested in the localization and extent of hearing abnormalities. 45% of the patients with chronic hypothyroidism showed a hearing loss. Of these, two patients had a pure conductive loss, seven a combined hearing loss and 16 a sensori-neural hearing loss. We demonstrated hair cell damage in 13 of the patients with chronic hypothyroidism. The hearing loss was mild to moderate in over 90% of the cases. Although several patients had a basocochlear hearing loss, no characteristic audiogram was found. There was a correlation between the conductive loss and the severity of the hypothyroidism. 50% of the patients showed a significant improvement in hearing after substitution therapy. The results of our examinations are discussed in detail.

    Description / Table of Contents: Summary A new diagnostic method for cytochemical detection of nonhaemiron in blood cells is reported. A final, magnification from 100.000 and more may be expected in normal light microscopy by this method. It was possible to demonstrate that the method is of significant diagnostic aid in the following haematological diseases in childhood: 1. The differential diagnosis of hyposideraemic anaemia. 2. The diagnosis of haemosiderosis. 3. The diagnosis of a sideroachrestic anaemia. The findings are demonstrated in cases with iron deficiency anaemia, anaemia due to infections and malignant diseases, haemosiderosis, haemolytic anaemia, thalassaemia major, vitamin B 12 deficiency, aplastic anaemia and leukaemia.
    Notes: Zusammenfassung Es wird über die diagnostischen Möglichkeiten einer neuen cytochemischen Methode (der Sulfid-Silber-Reaktion) zum Nachweis des Nichthämoglobineisens in Blutzellen berichtet. In vergleichenden cyto- und mikrochemischen Eisenstoffwechsel-untersuchungen konnte nachgewiesen werden, daß die Methode bei nachfolgend aufgeführten hämatologischen Erkrankungen des Kindesalters eine diagnostische Bedeutung hat. 1. Der Nachweis des Nichthämoglobineisens in den einzelnen Zellformen der Erythropoese ist entscheidend für die Differentialdiagnose der hyposiderämischen Anämien. Ein negativer Ausfall der Reaktion in nur einem Teil der basophilen Erythroblasten ist beweisend für eine echte Eisenmangelanämie. Ein positiver Befund in nur ganz vereinzelten Erythrocyten spricht für eine Pseudoeisenmangelanämie. 2. Cytochemisch nachweisbares Nichthämoglobineisen in den Lymphocyten ist eines der ersten Zeichen einer Hämosiderose und kann daher bei der Diagnose der Eisenüberladung eine entscheidende Hilfe sein. Das Ausmaß der Hämosiderose und ihre Behandlungsmöglichkeit ist mit Hilfe des Desferaltestes abzuschätzen. 3. Neben den Zeichen der Eisenüberladung läßt sich die Eisenverwertungsstörung durch den Nachweis von feinstkörnig verteiltem Eisen in den Erythrocyten nachweisen.

    Description / Table of Contents: Zusammenfassung Die spezifische gegen eine akute Leukämie gerichtete Wirksamkeit einer hochdosierten Prednisolon-Behandlung ist 24–48 Std nach Therapiebeginn an einem Aktivitätsabfall der bei der DNS-Synthese beteiligten Enzyme Thymidin-Kinase und DNS-Polymerase sowie der Einbauraten von DNS-Vorstufen — Thymidin und Desoxyuridin — nachweisbar. Entsprechende Stoffwechseluntersuchungen an leukämischen Blasten bei akuten Leukämien im Erwachsenen- und Kindesalter zeigen, daß sich die antileukämische Wirksamkeit der Corticosteroide auf die akuten Lymphoblasten- und undifferenzierten Leukämien beschränkt. Diese Ergebnisse werden durch klinische Verlaufsbeobachtungen und Angaben in der Literatur bestätigt. Es ergibt sich daraus, daß nur bei der akuten Lymphoblasten- und undifferenzierten Leukämie eine Indikation zur Behandlung mit Corticosteroiden in therapeutisch wirksamen Dosen besteht.
    Notes: Summary The specific action of high dose prednisolone treatment against acute leukemia is detected 24–48 hours after the initiation of treatment by decrease of enzyme activities involved in DNA-synthesis—thymidine-kinase and DNA-poly-merase—and of the incorporation rates of DNA-precursors—thymidine and deoxyuridine. Biochemical investigations of leukemic blast cells of acute leukemias in adults and children show, that the antileukemic effects of corticosteroids are limited to the acute lymphoblastic and undifferentiated leukemia. These results are confirmed by clinical observations and by different reports in the literature. Therefore high doses of corticosteroids are only valuable for the treatment of acute lymphoblastic and undifferentiated leukemia.

    Description / Table of Contents: Summary The results of cytologic and cytochemical investigations of blood cells in reactive (congenital infantil agranulocytosis) and leucemic (promyelocyticmonocytic-leucosis) monocytosis are presented. On the basis of cytochemical criteria the blood monocytes seem to be of myelocytic genesis in these diseases.
    Notes: Zusammenfassung Es werden vergleichende cytologische und cytochemische Untersuchungen an Blutzellen bei reaktiver Monocytose (kongenitale infantile Agranulocytose) und leukämischer Monocytose (Promyelocyten-Monocyten-Leukose) mitgeteilt. Aufgrund der cytochemischen Kriterien erscheint die myeloische Genese der Blutmonocyten bei diesen Erkrankungen wahrscheinlich.
