[Pleading for a double approach (author's transl)]

The writer criticizes the unifying models such as the classical, nineteenth century Psychiatry which makes of Psychiatry a mere branch of Medicine or Psychosomatic Medicine which imposes a "psychodynamic" pattern for the whole Medicine. He therefore recommends a dual and simultaneous approach destined to decipher two series of different signals and to meet somewhat different situations and decisions. This dual approach supposes a double training; it applies to the patient seen for the first time, but also to the patient in treatment who can either unveil significant symptoms of an underlying somatic disease or become somatically ill, with no relation with his psychiatric symptoms. Finally, a similar attitude of vigilance should be observed as far as supervision of chemotherapy is concerned.
