Abstract

Andrews' method of plotting n-dimensional data in 2 dimensions allows one to summarize all the data on one patient using a single curve. Comparisons have been made between different diagnostic groups on the basis of the 12 scales from the In-patient Multidimensional Psychiatric Scale (IMPS) using data from a sample of 787 newly admitted in-patients. For each diagnostic group, a figure was produced containing the Andrews' curves from all the patients in the group. Those groups that were particularly homogeneous or heterogeneous were noted. The main features of the different groups could be discerned.

[Management dialogue within multi-professional teams: contribution of psychoanalysis to integrated therapy of psychotic patients].

By means of case studies and experiences in supervising multiprofessional teams in psychiatric wards it is pointed out that the institutional frame of psychiatry is dynamically connected with the intrapsychic conflicts of the psychotic patients and their interpersonal defence. The understanding of the teammembers' countertransference prevents collusive patterns of relationship. This symbolizing process which is permanently endangered by the psychotic splitting mechanisms of the patients as well as by the institutional defence contributes to develop a "common language" in the multiprofessional teams. Furthermore psychoanalytic supervision enables the multiprofessional staff to understand the intrapsychic and the interactional dimension of the behaviour of the psychotic patient and to maintain their empathy even under difficult conditions.

Role of serotonin in the pathophysiology of depression: focus on the serotonin transporter.

Considerable evidence has accrued in the last two decades to support the hypothesis that alterations in serotonergic neuronal function in the central nervous system occur in patients with major depression. These findings include the following: (a) reduced cerebrospinal fluid (CSF) concentrations of 5-hydroxyindoleacetic acid (5-HIAA), the major metabolite of serotonin (5-HT) in drug-free depressed patients; (b) reduced concentrations of 5-HT and 5-HIAA in postmortem brain tissue of depressed and (or) suicidal patients; (c) decreased plasma tryptophan concentrations in depressed patients and a profound relapse in remitted depressed patients who have responded to a serotonergic antidepressant when brain tryptophan availability is reduced; (d) in general, all clinically efficacious antidepressants augment 5-HT neurotransmission following chronic treatment; (e) clinically efficacious antidepressant action by all inhibitors of 5-HT uptake; (f) increases in the density of 5-HT2 binding sites in postmortem brain tissue of depressed patients and suicide victims, as well as in platelets of drug-free depressed patients; (g) decreased number of 5-HT transporter (determined with [3H]imipramine or [3H]paroxetine) binding sites in postmortem brain tissue of suicide victims and depressed patients and in platelets of drug-free depressed patients. In our studies, this reduction in platelet 5-HT transporter binding is not due to prior antidepressant treatment of hypercortisolemia and is not observed in mania, Alzheimer disease, schizophrenia, panic disorder, fibromyalgia, or atypical depression. In a pilot study, this deficit predicted treatment response to an experimental antidepressant. These findings support the hypothesis that alterations in 5-HT neurons play a role in the pathophysiology of depression.
