[Influence of nutrition on the cellular defence mechanism (phagocytosis) of preterm and underweight babies during the first six weeks of life (author's transl)].

The phagocytic and NBT reduction indices of 94 preterm and underweight babies, divided into 7 groups and two weight classes, were observed over a period of six weeks while they were observed over a period of six weeks while they were given four commercial baby foods (Humana 0, Meb, Multival, Pomil). In all groups the mean values of both parameters were always within the standard range with only slight differences. In all test subjects, phagocytic activity decreased continuously during the first five weeks, and NBT reducing capacity during the first six weeks. Correlations could not be established between phagocytic or NBT reduction rate and birth weight or gestational age. As compared with the other groups there was a distinct lowering of the phagocytic indices in both Meb groups, which we think is nutrition-dependent and can be interpreted as the result of interaction between nutrition and immunological parameters.

[Principles of treatment and nursing of children with diphtheria (author's transl)].

The principles of treatment of diphtheria are discussed: in the present epidemic situation, diphtheritic children must be admitted to a pediatric hospital. The children need at least 3 to 4 weeks, to a large extent strict, bed rest. The basic concepts of the treatment of both peripheral circulatory weaknesses and of myocardial damage are communicated. Glucocorticoids have proved their value in myocarditis. Prophylactic digitalization is to be rejected. Confirmed heart failure is a binding indication for digitalization. A causal therapy for para- and metadiphtheritic paralysis does not exist. All forms must be treated with antibiotics nowadays. In croup, tracheotomy must not be delayed too long. The nursing must be left the best staff only and requires, in addition to a fundamental knowledge of the disease picture, an exceptional empathy in the particular, especially psychic, situation of the sick children.

Phagocyte dysfunction in common variable immune deficiency.

The history of a 13-year old boy is reported who suffered from frequent bacterial, enteroviral, and protozoal infections since late infancy. A decrease in the serum levels of IgG2, IgG3, IgA, a neutrophil dysfunction, and a partial cellular immune deficiency could be demonstrated. A deficiency of folic acid produced a pancytopenia which enhanced the patient's susceptibility to infections. The combined substitution of gammaglobulins and folic acid only was able to break this vicious cycle.

[Studies on the antimicrobial effect of vitamin D (author's transl)].

In in vitro studies vitamin D3 proved inhibitory on strains of Staphylococcus aureus, Streptococcus pyogenes, Klebsiella pneumoniae. Escherichia coli, and Candida albicans. In the presence of 5x10(4)-9x10(4) IU/ml vitamin D3 the organisms were killed or reacted with a marked growth inhibition.

On the influence of age on immunity in Down's syndrome.

In 23 subjects of different ages with Down's syndrome a number of parameters of non-specific defense of humoral and cellular immunity were investigated. While in all age groups complement factors C3, C4 and C5 as well as phagocytosis and NBT indices were in the normal range, a dysgammaglobulinaemia increasing with age with a hyperglobulinaemia of the IgG, IgA and IgD types was found, sparing immunoglobulins IgM and IgE. In addition the transformation capacity of peripheral blood lymphocytes decreased with age. This is understood as the consequence of premature aging of the thymus-dependent immune system.

[Basic features of diphtheria (author's transl)].

The basic features of diphtheria, especially clinical aspects, differential diagnosis and therapy are set out insofar as they are important for the general practitioner. The doctor, not the bacteriologist, must make the diagnosis. Serotherapy must be begun as rapidly as possible, and in adequate dosage. The patients must be carefully watched over in the interests of early detection of possible complications. Rest in bed is required in every case for at least 3 to 4 weeks, longer if possible. Even mild "localized" forms can lead to toxic damage during the course or subsequently. In infants, diphtheria may run its course as the well-defined clinical picture of "diphtheria intoxication" of infants.

Immunologic defense in bacterial and viral meningitis in children.

The investigation of a number of parameters of nonspecific and specific defense in 13 purulent and 18 mumps meningitides gave no indication of underlying primary immunodeficiencies. Only in the acute phase of mumps meningitis did we find a temporary suppression of cellular immune reactions measured as diminished rate of incorporation of thymidine by phytohemagglutinin-stimulated peripheral blood lymphocytes.

Defects in granulocyte function in various chromosome abnormalities (Down's-, Edwards'-, Cri-du-chat syndrome).

In five infants with autosomal aberrations and diminished resistance to infection (in spite of intact humoral and cellular immune mechanisms) several granulocyte functions (chemotaxis, phagocytosis, intracellular killing and metabolism of killing) were measured. A serum-dependent or a cell-dependent disturbance of phagocytosis of Candida albicans was found in two infants with cat-cry syndrome and one with trisomy 18. In one of these children there was an additional serum dependent defect of the killing of Candida albicans and of Staphylococcus aureus, serum levels of opsonins (IgG, IgM, CH50 and C3) being within normal range. An infant with trisomy 21 showed, in addition to a cellular defect of chemotaxis, a reduced cellular ability of the killing of Staphylococcus aureus and of Escherichia coli in autologous and AB-pool-serum. Phagocytosis of these bacteria remained normal.

Morphological and morphometric studies of the skeletal muscles of rachitic rats.

The question of "myopathia rachitica" was pursued in a disease progress study using rachitic rats. The length of the study was 18 weeks. During this time a discrete dystrophic myopathy formed. The morphometric examination showed muscle fibre diameters 8--24 mu less than those of healthy control rats in correlation with the degree of rachitis. The absence of fiber growth in the C fibres was conspicuous. The question of the relation of these findings to the inactivity, osteomalacia and changes in metabolism in rachitis was discussed. The myopathic changes can not be solely interpreted as a result of inactivity, but the cause of myopathia rachitica remains unclear.
