[A case of meningococcal sepsis].

We describe a 7-years boy by with a meningococcal sepsis due to Neisseria Meningitidis, with very serious evolution of cutaneous necrosis, initial D.I.C.

[Hypothesis for a pre- and post-natal relationship between mother and child].

The increasing interest in prenatal life triggered this study of the hypothetical possibilities of communication between mother and foetus. In this context, sound in the general sense is of capital importance since it permits the creation of an affective-cognitive bond between mother and child. The possibility of assessing this echographically adds extra interest to a problem that is already stimulating and open to a variety of horizons.

[A case of severe combined immunodeficiency].

The case described presented notable problems of diagnosis and treatment. The rapid onset of a massive tumoral syndrome in an infant with bronchiolitis dramatically worsened the clinical picture and led to the infant's death, posing the problem of the forms of congenital immune deficiency that may be associated with various aplastic and dysplastic haemopoietic alterations. The possibilities of treating such early hyperacute cases are limited given the lack of knowledge about the effects of drugs in such young children and the rapid deterioration of the patient's condition.

[Usefulness of plasmapheresis in the treatment of Blackfan-Diamond erythroid aplasia. Presentation of a case].

Plasmapheresis was attempted in a case where all other treatment had failed. As widely reported in the literature plasmapheresis is outstandingly effective in cases where antibodies are suspected and even in the absence of any such suspicion, its use is justified by the good results obtained. It is suggested that plasmapheresis is essential in the treatment of the particular pathology considered.
