Serotonin metabolism and other biochemical parameters in infantile autism. A controlled study of 22 autistic children.

The serotonin metabolism was extensively studied in 22 couples of autistic children and age- and sex-matched controls. Histamine, calcium, and uric acid were also measured in urine and whole blood or plasma. Autistics and controls did not differ in histamine, and only minor changes were noticed in calcium content. According to previous reports, serotonin levels were often, but not always, elevated in the blood of autistic children. Based on data including urinary serotonin and 5-hydroxyindoleacetic acid, platelet serotonin uptake and efflux, platelet monoamine oxidase and glutathione peroxidase activities, and uric acid and plasma tryptophan, the origin(s) of such hyperserotonemia in autism appear(s) to be of metabolic origin, i.e., a decreased catabolism and/or an increased biosynthesis of serotonin.

Catecholamines metabolism in infantile autism: a controlled study of 22 autistic children.

In a group of 22 autistic children aged 5 to 16 years and a group of normal controls matched for age and sex, catecholamines metabolism was investigated in plasma, platelets, and urine. This investigation was part of a research project in which several biological parameters (including serotonin) were explored simultaneously in the same children. In the autistic group, epinephrine and norepinephrine were significantly elevated in plasma, while epinephrin, norepinephrine, and dopamine were significantly lower in isolated platelets. No significant difference was found between the two groups for the urinary excretion of epinephrine, norepinephrine, dopamine, DOPAC, and MHPG. Other differences between the two groups in the statistical correlations of several biochemical parameters also suggest abnormalities of bioamine metabolism in the platelets of autistic children.

[New tympanomastoid repair in open technics: Galea's flap].

After an anatomical review, the authors describe the method for obtaining the temporo-parietal facial flap and its particularities in the rehabilitation of the canal down technic. The main indications of this flap are: the rehabilitation of unstable cavities, a Palva's flap alternation, a solution to the filling up after petrectomy or enlarged canal down technic.

[A "condemned" child. Case of borderline personality disorder].

The import of this observation resides in the significance of the patient's destiny and in the poor organization of his personality, indicating that defense mechanisms may have been prevented from building up as a result of the bearing of real and phantasmic events on his mental working. We speculate that a mechanism as essential as interiorization could not develop, as a direct result of the continuous confrontation of conflicts with a disrupted reality and the recollection of this last. The limits constituted by death and incest could not be normally interiorized and integrated within the psychic organization of this young boy, "doomed" at the age of four, and perhaps even earlier.

[Psychoanalytic therapy in adolescence].

Psychoanalytic therapies in adolescence can be classified into four groups: the analytic cure or "standard cure", psychoanalytic psychotherapy (PP), psychoanalytic psychodrama and psychoanalytic relaxation psychotherapy. In other instances, the psychoanalyst works with the adolescent's family or with the staff working in an institution for adolescents, but this does not involve a direct relationship between the psychoanalyst and the adolescent. In adolescence, PP and psychodrama seem to be the most readily used psychoanalytical methods.

[Psychiatry of adolescence. Prevention of mental diseases in adults].

Several impediments to the recognition of psychological disorders in adolescents are analyzed. In spite of the difficulties, it is worthwhile to overcome these obstacles. Indeed, it must be pointed out that the therapy of psychological disturbances during adolescence has a preventive effect upon longstanding psychiatric disorders in adulthood. Psychological manifestations in adolescence can be classed into four groups: the normal process of transformation, transient psychopathological reactions to transformation, conflictual organizations and severe impediments to the process of transformation. To these four clinical groups answer different consultation settings.

[Depression in adolescents].

After having believed that depression is a normal feature of adolescence, most practitioners discriminate between the moderate, transient, depressive feelings, which are indeed part of the normal process of adolescence, and the various forms of true depression that may occur at this age. The problem of "depressive equivalents" is probably the most studied. Our opinion, based on a clinical and psychodynamic viewpoint, is that four types of depression can be distinguished in adolescence: anxious-depressive reactions, inferiority depression, abandonment depression and melancholic depression. These four conditions share a basic depressive reaction typified by a psychomotor slowness and "freezing" of feelings, ideas and motions.

[Partial deletion of the short arm of chromosome 3. Report of a case (author's transl)].

A patient with partial deletion 3p is reported. Only one other patient has been previously reported in the literature. Features the two share include microcephaly, failure to thrive, ptosis, symophrys, a broad and flat nose, a prominent maxilla, an over developed chin, and an increased number of loops on the finger tips. These observations are compared in type and countertype with known observations of trisomy 3p and of 3q duplication/3p deletion.

[Adolescents and drug-addiction (author's transl)].

Drug-addiction is one of the most common psychopathologic behavior in adolescents. Three questions were considered in this study: how does the adolescent meet drug? What does drug-addiction mean? Which practical attitudes could be proposed? An answer to these three fundamental questions is drawn through three cases.
