[The concept of psychotic crisis and its psychoanalytic treatment].

With regard to psychoses, the notions of crisis, crisis intervention and crisis centres are somewhat ill-defined. The author emphasizes that, contrary to the psychiatric field which aims to reduce symptoms, psychoanalysis does not attempt to examine the phenomenology of a psychosis, but rather focus on the structure that underlies it. The author goes on to show in what way the psychoanalytic viewpoint can help to define the notion of crisis and suggests an intervention method designed specifically for crisis situations.

[Hyperthyroidism and atrioventricular heart block (author's transl)].

Two cases of thyrotoxicosis including a first-degree heart block are reported; a study of action potentials of the bundle of His was achieved in the second case. The association atrioventricular block-hyperthyroidism is unusual but does not seem to be a pure coincidence. The direct effect of thyroid hormon on the myocardium is supposed to be responsible for the conduction disturbance; its disappearance with the cure of the thyrotoxicosis is a favourable argument for a relation of causality.
