    Notes: Summary The brains have been examined of 24 children with thymic alymphoplasia who suffered from severe humoral and cellular immunological deficiencies. In 11 of them there was extensive gliosis of the brain stem, and in 5, a subacute polioencephalitis restricted to this region. The appearances suggested a chronic viral infection of the brain, and electron microscopy of one case has revealed rounded intra-nuclear probable virions 18–22 nm in diameter. The chronic scarring and sparse inflammatory lesions resemble a ‘degeneration’ rather than a typical inflammatory disorder, and mimic viral encephalitis in immunosuppressed animals. The possibility is discussed that other degenerative disorders of the nervous system in man might be due to virus infections associated with impaired immunity.

    Description / Table of Contents: Zusammenfassung Das auftreten nichtchromaffiner Paragangliome im Kindesalter ist relativ selten und nur wenig bekannt. Da eine Fehldeutung dieser Tumoren zu ernsten therapeutischen Schwierigkeiten führen kann, werden an Hand von zwei Eigenbeobachtungen und 34 Fällen aus der Literatur (1919–1969) klinische und morphologische Besonderheiten der verschiedenen lokalisierten Paragangliome erörtert. Mit steigendem Lebensalter treten die Tumoren häufiger auf. Eine geschlechtliche Disposition im Kindesalter besteht nicht. Ebenso wie im Erwachsenenalter werden auch bei Kindern neben hormonal inaktiven auch hormonal aktive Tumoren beobachtet, die Katecholamine produzieren und von den Phäochromocytomen klinisch abgegrenzt werden müssen. Die Metastasierungs- und Rezidivneigung im Kindesalter ist wesentlich höher als bei erwachsenen Patienten. Differentialdiagnostisch können durch histologische Spezialfärbungen Hämangiome und Hämangioendotheliome sowie die Glomustumoren des Typ Masson von den nichtchromaffinen Paragangliomen abgegrenzt werden. Auch die Abrikossoff-Tumoren und die alveolären Weichteilsarkome lassen sich in der Regel histologisch und histochemisch von nichtchromaffinen Paragangliomen unterscheiden. Die Therapie der Wahl besteht trotz einer relativ hohen postoperativen Mortalität zur Zeit in der operativen Entfernung der nichtchromaffinen Paragangliome.
    Notes: Abstract The incidence of non-chromaffin paragangliomas in children is rare and therefore hardly ever thought of. However, a false diagnosis of these tumours can lead to severe therapeutical difficulties. For this reason the clinical and morphological features of paragangliomas of varying localisation are discussed, on the basis of 2 own cases and 34 cases reviewed in the literature (1919–1969). The rate of tumour growth increases with increasing age. A sex dependence was not observed. As in adults, hormone-active and inactive tumours are also observed in children. These tumours produce catecholamines and must therefore be distinguished clinically from phaeochromocytomas. Metastases and recurrences are more frequent in children than in adults. Haemangioma, haemangioendothelioma, and the Masson glomus-tumour must be considered in the differential diagnosis; they can be histologically excluded by special staining methods. In most cases Abricossoff-tumour and alveolar soft part sarcomas can also be distinguished by histological and histochemical methods from non-chromaffin paragangliomas. At present the therapy of choice is the surgical removal of non-chromaffin paragangliomas, although there is a high frequence of post-operative mortality.

    Notes: Abstract Two studies are reported in which stimulant drugs (Methylphenidate and Dextroamphetamine) are administered to children with minimal brain dysfunction. The drugs produce highly significant improvement in one study in the total raw scores of the figure drawings, compared with placebo. Scores presumed to measure social maturity or social interest were not affected by the drug treatments. It is suggested that the drugs probably change figure drawings by means of their influence on attention span or the child's need to perform well in the drawing task. Inconsistencies between results of different studies are accounted for by sample heterogeneity which becomes apparent when cluster analysis is employed to refine diagnosis.

    Notes: Abstract Coffeine, meprobamate, and a placebo were investigated for their effects upon the critical flicker fusion (FVF) at two groups of persons of different age (group A=23 [20–25] and group B=10 [8–16] years old). Coffeine blocked always the decrease of the FVF, whereas the FVF came down after meprobamate muche more than after placebo. A different reaction between the members of the two groups A and B was seen after placebo.
