[Psychic and psychosomatic symptom in pediatrics (author's transl)]

From the intimate relationship between somatic and psychic aspects, certain characteristics of the psychic or psychosomatic symptom in the child are sketched and the evolution from the psychic conflict to the elaboration of an specific symptom. The meaning of the symptom as a language or a means of expression of the child is pointed out, as well as the individual significance of the symptom in each clinical case, avoiding mechanical and reducing schemes. The importance of the "language of the body" in the infant and the symptom as a sign, signifies or symbol or as a unconscious fantasy related to the organ function in the school child. The importance of the first affective contacts in the child as etiopathogenic formations. Some anamnestic guidelines and practical evaluations are developed in each infantile functional disorder. Finally, the need for a deep study of the psychosomatic sphere is emphasized, looking for a balance between an attitude of underevaluation and one of hypertrophy, goal attainable by means of the integration of pediatrician infantile psychiatrists in an interdisciplinary team.
