    Description / Table of Contents: Summary Dysmorphophobia as a new psychiatric syndrome was described by the italian psychiatrist Morselli in 1891. Dysmorphophobic symptoms are associated with several other psychiatric disorders. The term of dysmorphophobia will be discussed along a theoretical review. We present the case of a 20-year-old patient with dysmorphophobic symptoms. In the scope of ICD 10, DSM-III-R/DSM IV diagnostical criteria we outline problems of the diagnostical classification of dysmorphophobic signs.
    Notes: Zusammenfassung Die von Morselli 1891 als neues klinisches Syndrom beschriebene Dysmorphophobie findet sich bei verschiedenen psychiatrischen Krankheitsbildern. Anhand einer theoretischen Übersicht wird der Begriff der Dysmorphophobie skizziert. Dysmorphophobe Symptome bei verschiedenen psychiatrischen Erkrankungen werden erläutert. Anhand einer kasuistischen Darstellung werden Probleme der diagnostischen Zuordnung dysmorphophober Symptome in den modernen Klassifikationssystemen diskutiert.

    Description / Table of Contents: Summary The construct Quality of Life (QoL) is investigated by metaanalysis of eight (inter)nationally validated questionnaires in a multicenter study. Data have been collected in a mentally healthy (n=479), a depressed (n=171) and a schizophrenic (n=139) sample. Conventional psychometric criteria and a facet analytical methodology have been applied. The resulting questionnaire „Modular System for Quality of Life” (MSQoL) consists of a core module with 47 items (one „G-factor” and six subdimensions), which is sufficiently valid for all three samples. Additionally, there are four specific modules (demography, family, partnership, profession). No specific modules can be identified for the psychopathological subgroups. The validated radex structure for subjective QoL offers the opportunity for a cumulative research design and for adaptations to the actual setting.
    Notes: Zusammenfassung In einer von der Arbeitsgruppe „Lebensqualität (LQ)” der „Arbeitsgemeinschaft für Methodik und Dokumentation in der Psychiatrie” (AMDP) unterstützten multizentrischen Studie wird das Konstrukt Lebensqualität (LQ) anhand von acht (inter)national validierten Erhebungsinstrumenten sowie einer gesunden (n=479), einer depressiven (n=171) und einer schizophrenen (n=139) Stichprobe metaanalytisch untersucht. Neben herkömmlichen psychometrischen Kriterien liegt der methodische Schwerpunkt dabei auf einem facettenanalytischen Vorgehen. Der resultierende Fragebogen „Modulares System zur Lebensqualität” (MSLQ) besteht aus einem für alle 3 Stichproben hinreichend validen Kernmodul mit 47 Items (ein „G-Faktor” und 6 Subdimensionen) sowie 4 spezifischen Modulen (Demographie, Familie, Partnerschaft, Beruf). Für die psychopathologischen Subgruppen lassen sich keine spezifischen Module etablieren. Die validierte Struktur der subjektiv eingeschätzten Lebensqualität (in Form einer facettenanalytischen Radexkonstellation) bietet die Möglichkeit zu einer kumulativ angelegten Forschung und einer untersuchungsspezifischen Anpassung des MSLQ.

    Description / Table of Contents: Summary Delusion as a phenomenon was always in the focus of psychiatric interest. Explanations for its origin reach from disturbed perception or affect to deficits in cognition. In our study we investigated 20 deluded, 20 depressive and 20 healthy subjects in order to find out differences in decision making, while a neutral test situation. Our hypothesis was that deluded subjects need less information for decision making and tend less to change their decision, made before, than both control groups will do this. For examination our hypothesis a modified version of “Probabilistic Inference Task” by Philips and Edwards was performed. In summary we found that deluded subjects need less information for decisions making than the control groups. Furthermore, decision making of deluded subjects seems more impulsive and less referring to formal logical criteria than it was found in depressed and healthy volunteers.
    Notes: Zusammenfassung Das Phänomen Wahn steht seit jeher im Zentrum des psychiatrischen Interesses. Die in der Vielzahl von Hypothesen zur Wahnentstehung diskutierten Ursachen reichen von Störungen der Wahrnehmung oder des Affektes bis hin zu kognitiven Störungen. In unserer Untersuchung mit 20 wahnhaften, 20 depressiven und 20 gesunden Probanden gingen wir der Frage nach, ob sich zwischen den drei genannten Gruppen Unterschiede im Urteilsverhalten während einer neutralen Testsituation aufzeigen lassen. Unsere Hypothese dabei war, daß wahnhafte Probanden zur Urteilsbildung deutlich weniger Information heranziehen und an ihren einmal gefällten Urteilen rigider festhalten, als dies bei einer gesunden und depressiven Kontrollgruppe der Fall ist. Zur Überprüfung der Hypothesen wurde eine modifizierte Version des “Probabilistic Inference Task” von Philips and Edwards eingesetzt. Zusammenfassend zeigte sich, daß die Gruppe der wahnhaften Probanden zur Entscheidungsfindung signifikant weniger Informationen als die beiden Kontrollgruppen benötigte. Das Urteilsverhalten insgesamt erschien bei den wahnhaften Probanden deutlich impulsiver und weniger auf formallogisch nachvollziehbaren Kriterien beruhend als dies in den beiden anderen Probandengruppen der Fall war.

    Description / Table of Contents: Abstract After surgical operations delirium can occur as a serious and possible lethal complication in about 5–15% of patients. Additionally, risk factors such as old age, polymedication, organic and psychiatric diseases raise the incidence. After open-heart- and orthopedic surgery more than half of the patients are affected. Delirium has negative effects on postoperative mobilization and reconvalescence and prolongs treatment on the ward. It is discussed in the literature that delirium may induce dementia in older patients. The correction of metabolic- and electrolyte imbalances, as well as the therapy of neurologic and psychiatric diseases, belongs to prophylactic treatment. Environmental conditions which facilitate reorientation of the patient after operation have beneficial effects. Some success has been achieved by using the nootropic substance piracetam as a prophylactic. In acute treatment, the butyrophenon-neuroleptic haloperidol is the drug of choice. In delirium caused by intoxication with anticholinergic agents, physostigmin is indicated. Benzodiazepines, clonidine and clomethiazole are used in particular for the treatment of withdrawal delirium.
    Notes: Zusammenfassung Nach operativen Eingriffen kommt es bei 5 bis 15% der Patienten zu einem Delir, welches eine ernste und potentiell tödliche Komplikation darstellt. Bei zusätzlich bestehenden Risikofaktoren wie hohem Alter, medikamentöser Mehrfachtherapie, somatischen und psychiatrischen Störungen findet sich eine noch wesentlich höhere Inzidenz. Bei Operationen am offenen Herzen und orthopädischen Eingriffen sind über die Hälfte der Patienten betroffen. Das Delir beeinträchtigt die postoperative Mobilisierung und Rekonvaleszenz der Patienten und führt zur Verlängerung des stationären Aufenthalts. Die Gefahr einer dementiellen Entwicklung als Spätfolge des Delir bei älteren Patienten wird in der Literatur diskutiert. Zu den Maßnahmen der Prophylaxe zählen die Behandlung von metabolischen Entgleisungen, Ausgleich von Elektrolytstörungen und Therapie von neurologischen und psychiatrischen Erkrankungen. Verhaltensmaßnahmen, die die Orientierung des Patienten nach der Operation erleichtern, haben eine günstige Wirkung. Erfolge wurden durch die prophylaktische Verabreichung des Nootropikums Piracetam berichtet. In der Akutbehandlung ist das Butyrophenon-Neuroleptikum Haloperidol Mittel der Wahl zur Sedierung. Bei Delirien auf der Grundlage einer Intoxikation mit anticholinerg wirkenden Pharmaka ist Physostigmin indiziert. Benzodiazepine, Clonidin und Clomethiazol kommen v.a. bei der Behandlung des Entzugsdelir zum Einsatz.

    Description / Table of Contents: Summary A potential impact of tricyclic antidepressants on oral anticoagulation is controversial. Phenprocoumon – the most commonly used anticoagulant in Germany – is rarely considered in clinical trials. In the present study, a potential drug-drug interaction between phenprocoumon and tricyclics, causing an alteration in prothrombinemic effects, has been investigated. In eleven patients simultaneously receiving tricyclic antidepressants and phenprocoumon the course of Quick values and the phenprocoumon dosages were compared to a control group of eleven phenprocoumon treated patients not receiving tricyclics. Quick value deviations from the individually required therapeutic ranges 〉25%, as well as frequent changes in the phenprocoumon dosages were indicators of an inconstant oral anticoagulation and a possible interaction. The results showed unstable prothrombinemic effects throughout tricyclic antidepressant therapy. The average Quick value deviation amounted to 68.7% in the patients group and to 13.1% in the control group. Additionally, there was an average change in phenprocoumon dosage of 0.6 in the patients group and of 0.2 in the control group. Further controlled studies are certainly warranted to specifically answer the question of a clinically relevant drug-drug interaction.
    Notes: Zusammenfassung Eine mögliche Beeinflussung der Antikoagulanzientherapie durch trizyklische Antidepressiva wird bislang unterschiedlich bewertet. Vor allem das in Deutschland therapeutisch eingesetzte Antikoagulanz Phenprocoumon bleibt bei Untersuchungen nahezu unberücksichtigt. Die vorliegende retrospektive Studie wurde unter der Fragestellung einer potentiellen Arzneimittelinteraktion zwischen Phenprocoumon und Trizyklika durchgeführt. Bei 11 gleichzeitig mit Trizyklika und Phenprocoumon behandelten Patienten und 11 antikoagulierten Kontrollen ohne antidepressive Therapie erfolgte eine Gegenüberstellung von Quickwertverlauf und Phenprocoumondosis während und außerhalb trizyklischer Therapie. Quickwertabweichungen vom therapeutischen Bereich 〉25% und häufige Phenprocoumon-Dosiswechsel galten als Zeichen einer instabilen Antikoagulation und einer zugrundeliegenden Interaktion. Sowohl im intraindividuellen Patientenvergleich wie auch in der Gegenüberstellung von Patienten- und Kontrollkollektiv wurde eine instabile Phenprocoumonwirkung unter Trizyklikatherapie gezeigt. Die mittlere Quickwertabweichung [mQWA] betrug im Patientenkollektiv 68,7%, im Kontrollkollektiv 13,1%. Für das Patientenkollektiv wurde eine mittlere Dosiswechselzahl [mDWZ] von 0,6 errechnet. Im Kontrollkollektiv lag die mDWZ bei 0,2. Inwiefern unsere Beobachtungen als Indikator einer potentiellen Arzneimittelinteraktion gelten können, ist in diesem Rahmen nicht abschließend zu beurteilen. Zur endgültigen Abklärung der Fragestellung erscheint die Durchführung prospektiver Studien angezeigt.

    Notes: Abstract The primary objective of this study was to test hypotheses about the relationship between HMPAO-SPECT findings and probable Alzheimer’s disease (DAT) in a relatively large sample of patients diagnosed according to DSM-III-R. SPECT patterns of 20 controls and 116 DAT patients were investigated. Left and right frontal, temporal, parietal and occipital regions of the brain were rated as showing a hypoperfusion or not. A wide variety of patterns were found and these are described in detail below. In DAT patients, temporal and/or parietal regions were affected significantly more often (88%, p 〉 0.001) than frontal and/or occipital regions (70%). A bilateral temporoparietal pattern, which has been repeatedly reported as typical for DAT, was observed in 48% of DAT patients, but also in 25% of controls, and did not differentiate significantly between these two groups (p 〉 0.05). Conversely, more than three regions with hypoperfusion were observed significantly more often in DAT patients (48%, p 〈 0.01) than in controls (10%). In DAT patients, the number of regions with hypoperfusion correlated significantly with the score of the Mini Mental State Examination (MMSE, r = 0.33, p 〈 0.001). The frequency of at least one hypoperfusion was approximately equal in left and right hemispheres (77% vs. 73%, p = 0.2). The hypothesis that cognitive decline in DAT starts in the temporal regions was tested in 14 SPECT patterns showing only one region with hypoperfusion. In 12 of these patterns, a temporal region was in fact affected (p 〈 0.001). Whereas hypoperfusion in frontal areas was not accompanied by a significantly lower MMSE than when only temporoparietal regions were affected, MMSE scores were significantly lower when occipital regions were affected in addition to temporoparietal regions (p 〈 0.05). The clinical use of SPECT findings was tested in discriminating analyses with the MMSE and a delayed recall test as additional predictors of DAT. Whereas the MMSE and the delayed recall test differentiated significantly between DAT patients and controls, SPECT findings yielded no further differentiation. In conclusion, the theoretical and clinical implications of SPECT findings and their relationships to other physiological and psychological variables deserve further investigation.

    Notes: Abstract Previous MRI studies have shown differences in corpus callosum size between schizophrenic patients and controls. The corpus callosum (CC), as the main interhemispheric fiber tract, plays an important role in interhemispheric integration and communication. Though MRI studies suggest smaller CC in schizophrenia, there are still conflicting findings. Using in vivo magnetic resonance imaging, it was investigated whether the midsagittal area of CC differs between twenty-three right-handed male schizophrenic patients and twenty-three matched controls. Total CC area, five subregions of CC, total brain volume, gray and white matter were measured. No differences between schizophrenic patients and controls were found regarding all CC measurements, total brain volume, and gray matter tissue. However, a significant reduction of white matter tissue in the patient group emerged. There was no correlation between CC morphology and clinical variables such as age of onset, length of illness or symptom severity. Interestingly, five schizophrenic patients with a positive family history of schizophrenia showed significant reduction of the subregion C3, associated with a reduced total brain and gray and white matter volume. Significant reduction in the CC and its subregions was not confirmed in this group of patients with schizophrenia. In the subgroup of schizophrenic patients with a positive family history of schizophrenia, a significant reduction of the subregion corresponding to a part of the trunk of the CC was found.

    Notes: Abstract It has been reported recently that the prophylactic efficacy of lithium is a transient phenomenon in many patients. Other studies suggest sustained efficacy against affective recurrences for many years. As this issue is of major therapeutic relevance, published literature considering changes in lithium efficacy over time has been reviewed. The present review includes a critical evaluation of the data and the methodology which yielded these controversial results. Considering the published data discussed in this review, the balance of evidence does not indicate a general loss of lithium efficacy in the prophylaxis of major affective disorders. A supposed persistence of the prophylactic effects in general does not, however, exclude the reappearance of affective recurrences after years of successful treatment in individual cases. Possible reasons for this phenomenon are discussed.
