[Suicidal ideation of prisoners : Influence of duration of imprisonment, personality traits and disorders]. / Suizidalität von Inhaftierten : Einfluss von Haftdauer, Persönlichkeitsauffälligkeiten und Persönlichkeitsstörungen.

BACKGROUND: Although in recent years many efforts have been made in suicide prevention, suicidal ideation in prison is still a major problem. The present study is part of a project being carried out in Saxony, Germany on the investigation and prevention of suicide in prisons. OBJECTIVE: The aim of this study was to determine whether the duration of imprisonment, personality traits and personality disorders have an influence on the suicidal ideation of prisoners. MATERIAL AND METHODS: In this study 113 volunteers among prisoners from 6 prisons in Saxony participated in a structured interview and filled out several questionnaires on sociodemographic details, personality using the personality style and disorder inventory (PSSI) and the assessment of DSM-IV personality disorders (ADP-IV) questionnaire as well as attitudes towards suicide using the questionnaire on stressful social experiences (FBS) and the Viennese instrument for suicidality on correctional institutions (VISCI). RESULTS: Significant correlations were found between personality traits and personality disorders and suicidal ideation and suicide attempts. A positive correlation was also found between personality disorders and scores in the VISCI. High scores in the PSSI were correlated with all aspects of suicidal ideation; however, length of time spent in prison and total duration of imprisonment appeared to have little impact on suicide parameters and were only correlated with the self-declared current suicidal ideation. DISCUSSION: Although there were some limitations, this study could confirm data in the literature that personality disorders are associated with an increased risk of suicidal ideation in prisoners. The lack of association of suicidal thoughts as measured in this study with the total time spent in prison and duration of imprisonment is in contradiction to the results of other studies and warrants further investigation.

Does lithium reduce acute suicidal ideation and behavior? A protocol for a randomized, placebo-controlled multicenter trial of lithium plus Treatment As Usual (TAU) in patients with suicidal major depressive episode.

BACKGROUND: Lithium has proven suicide preventing effects in the long-term treatment of patients with affective disorders. Clinical evidence from case reports indicate that this effect may occur early on at the beginning of lithium treatment. The impact of lithium treatment on acute suicidal thoughts and/or behavior has not been systematically studied in a controlled trial. The primary objective of this confirmatory study is to determine the association between lithium therapy and acute suicidal ideation and/or suicidal behavior in inpatients with a major depressive episode (MDE, unipolar and bipolar disorder according to DSM IV criteria). The specific aim is to test the hypothesis that lithium plus treatment as usual (TAU), compared to placebo plus TAU, results in a significantly greater decrease in suicidal ideation and/or behavior over 5 weeks in inpatients with MDE. METHODS/DESIGN: We initiated a randomized, placebo-controlled multicenter trial. Patients with the diagnosis of a moderate to severe depressive episode and suicidal thoughts and/or suicidal behavior measured with the Sheehan-Suicidality-Tracking Scale (S-STS) will be randomly allocated to add lithium or placebo to their treatment as usual. Change in the clinician administered S-STS from the initial to the final visit will be the primary outcome. DISCUSSION: There is an urgent need to identify treatments that will acutely decrease suicidal ideation and/or suicidal behavior. The results of this study will demonstrate whether lithium reduces suicidal ideation and behavior within the first 5 weeks of treatment. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02039479.

[Non-cardiac and non-pulmonary causes of dyspnea]. / Nichtkardiale und nichtpulmonale Ursachen der Dyspnoe.

In addition to cardiac and pulmonary diseases there is a broad variety of different underlying causes of dyspnea. The spectrum includes the different forms of anemia, all causes of upper airway obstructions, neuromuscular diseases and psychopathological disorders. This article gives a brief review of the entire spectrum by providing information about differential diagnostics as well as the main therapeutic principles. A field of growing interest is dyspnea in the context of palliative care.

The effect of age, sex, smoking and co-medication on serum levels of venlafaxine and O-desmethylvenlafaxine under naturalistic conditions.

INTRODUCTION: Venlafaxine (VEN) is a modern antidepressant which exerts both serotonin and norepinephrine reuptake inhibition. In this study we examined the influence of age, sex, smoking, and co-medication on serum levels of VEN and its metabolite O-desmethylvenlafaxine (ODVEN) in patients treated with VEN under naturalistic conditions. METHODS: We retrospectively evaluated 478 TDM analyses of VEN requested in the Pychiatric University Hospitals of Mainz, Regensburg, and Würzburg. The determination of serum levels was performed by virtually identical chromatographic methods in the TDM laboratories of the participating hospitals. RESULTS: Serum levels varied widely on each dose level. Women had about 30% higher dose-corrected serum levels of VEN and ODVEN than men (p<0.01), and patients older than 60 years showed about 46% higher levels of both compounds than younger ones (p<0.01). In smokers, mean serum levels of ODVEN were 21% lower than in non-smokers. Combining these variables a considerable increase of the differences between the subgroups was found indicating an additive effect. ANOVA over the 8 different groups was significant for ODVEN (p<0.01) and sum (p<0.01), but not for VEN (n.s.). Co-medication with other psychotropic drugs was associated with a decreasing ODVEN/VEN ratio indicating a reduced metabolism in patients receiving polypharmacy. DISCUSSION: These findings show that TDM is useful to identify factors affecting the pharmacokinetic properties of VEN. It is concluded that sex, age and smoking should be considered for optimal dosing of patients with VEN.

["My disease is one of the mind and difficult to define": Robert Walser (1879-1956) and his mental illness]. / "Meine Krankheit ist eine Kopfkrankheit, die schwer zu definieren ist" : Robert Walser (1878-1956) in seiner psychischen Erkrankung.

Robert Walser (1878-1956) is among the most prominent German-speaking writers born in Switzerland. His early writings are fascinating due to his intensive affectivity and oneiric experiences; his late work impresses through his idiosyncratic use of language and his micrographs. Due to a psychotic disease he stayed in Swiss Mental State Hospitals (Waldau and Herisau) throughout the final 27 years of his life. According to his case records Robert Walser suffered from a schizophrenic disorder (ICD-10) and from a combined sluggish/manneristic catatonia according to K. Leonhard. Walser's psychotic disorder was characterized by a chronic course with sharp-cut symptomatology with stiff postures, repetitive behaviour, movement mannerisms and omissions (manneristic component) complemented by loss of incentive, severe autism and persistent verbal hallucinations (speech-sluggish component). In the late stages his psychopathology affected the process of thinking and writing in a specific manner: his handwriting became illegibly small, and his train of thoughts did not get to the point. At age 54 he stopped writing when transferred from Waldau to Herisau, and subsequently, due to manneristic omission, he was never again able to restart literary writing. The analysis of Robert Walser's psychotic disease may contribute to a deeper understanding of his literary production, which influenced such classical German authors like Franz Kafka, Hermann Hesse and Robert Musil.

Comparison of combined psycho- and pharmacotherapy with monotherapy in anxiety disorders: controversial viewpoints and clinical perspectives.

Anxiety disorders are among the most frequent psychiatric disorders. Experimental evidence supports both psychotherapy as well as pharmacotherapy as effective treatments. There is, however, a controversy concerning the efficacy of a combination of both approaches. While some studies suggest that combined treatment enhances efficacy, others report conflicting results. This article traces the positions in this debate. We present the results from two recent meta-analyses and discuss implications for clinical practice and further research. We suggest that a research strategy that strives to establish differential indications based on patient characteristics should be preferred over attempts to reach a global judgement of the question, which appears too simplistic given the complexity of the issue.

Therapeutic drug monitoring of tricyclic antidepressants in everyday clinical practice.

Data about therapeutic drug monitoring (TDM) of psychotropic medications are often obtained from samples of highly selected individuals, who may not be representative for the average psychiatric patient. These data therefore may have limitations with regard to their transferability to everyday clinical practice. Therefore studies under naturalistic conditions are important to clarify the full clinical relevance of TDM. We retrospectively evaluated all TDM-analyses of the tricyclic antidepressants (TCA) amitriptyline and clomipramine during a 12-month period in an unselected sample of patients in a standard clinical setting. We especially examined the relationship between serum levels on one hand and clinical response and adverse effects on the other hand. In patients with amitriptyline, responders showed a significantly higher serum level than non-responders, whereas in patients with clomipramine a serum level within the recommended therapeutic range was associated with clinical response. We also found significantly higher serum concentrations in patients with adverse effects compared to patients without adverse effects in the clomipramine group. No such relationship could be shown in patients treated with amitriptyline. Our results suggest that therapeutic ranges in naturalistic settings in some ways differ from those obtained in controlled clinical settings and that TDM studies in everyday clinical practice are necessary and beneficial.

Strong seduction: impulsivity and the impact of contextual cues on instrumental behavior in alcohol dependence.

Alcohol-related cues acquire incentive salience through Pavlovian conditioning and then can markedly affect instrumental behavior of alcohol-dependent patients to promote relapse. However, it is unclear whether similar effects occur with alcohol-unrelated cues. We tested 116 early-abstinent alcohol-dependent patients and 91 healthy controls who completed a delay discounting task to assess choice impulsivity, and a Pavlovian-to-instrumental transfer (PIT) paradigm employing both alcohol-unrelated and alcohol-related stimuli. To modify instrumental choice behavior, we tiled the background of the computer screen either with conditioned stimuli (CS) previously generated by pairing abstract pictures with pictures indicating monetary gains or losses, or with pictures displaying alcohol or water beverages. CS paired to money gains and losses affected instrumental choices differently. This PIT effect was significantly more pronounced in patients compared to controls, and the group difference was mainly driven by highly impulsive patients. The PIT effect was particularly strong in trials in which the instrumental stimulus required inhibition of instrumental response behavior and the background CS was associated to monetary gains. Under that condition, patients performed inappropriate approach behavior, contrary to their previously formed behavioral intention. Surprisingly, the effect of alcohol and water pictures as background stimuli resembled that of aversive and appetitive CS, respectively. These findings suggest that positively valenced background CS can provoke dysfunctional instrumental approach behavior in impulsive alcohol-dependent patients. Consequently, in real life they might be easily seduced by environmental cues to engage in actions thwarting their long-term goals. Such behaviors may include, but are not limited to, approaching alcohol.

Echogenicity of substantia nigra determined by transcranial ultrasound correlates with severity of parkinsonian symptoms induced by neuroleptic therapy.

BACKGROUND: Increased echogenicity of the substantia nigra (SN) detected by transcranial sonography is a characteristic ultrasound feature of Parkinson's disease. This ultrasound feature can also be detected in a subgroup of healthy adults. In recent studies, healthy subjects with this ultrasound feature showed a reduced [(18)F]-Dopa uptake on positron emission tomography (PET), indicating a subclinical alteration of the nigrostriatal system. This study was designed to evaluate whether the severity of neuroleptic side effects is related to the echo-feature of the SN. METHODS: In the retrospective part of the study, 93 psychiatric patients with either definite and severe parkinsonism after neuroleptic treatment (n = 52) or with no or minimal parkinsonian symptoms (n = 41) were included and underwent transcranial sonography to measure the extension of hyperechogenic areas at the SN. In addition, in the prospective part 11 patients with an acute psychotic episode requiring first-ever neuroleptic treatment underwent ultrasound examination. Subsequently, neuroleptic-induced parkinsonian signs were assessed prospectively. RESULTS: In the retrospective part of the study, patients with severe neuroleptic-induced parkinsonism had more extended echogenic signals at the SN than those with low echogenic SN (U-test; p <.01). The prospective part of the study showed that the severity of parkinsonian symptoms correlated with the echogenicity of the substantia nigra (Spearman's rank: p <.01). CONCLUSIONS: Increased echogenicity of the substantia nigra is associated with impaired function of the nigrostriatal system that can be disclosed by neuroleptic drugs.

Cycloid psychoses are not part of a bipolar affective spectrum: results of a controlled family study.

BACKGROUND: Whereas a growing body of evidence suggests that cycloid psychoses have to be separated from schizophrenic psychoses, their relations to bipolar affective disorder are less clear. To further clarify this issue a controlled family study was undertaken. METHODS: All living and traceable adult first-degree relatives of 45 cycloid psychotic, 32 manic-depressive and 27 control probands were personally examined by an experienced psychiatrist blind to the diagnosis of the index proband. Data about not traceable relatives were collected by the "Family-History"-Method. A catamnestic diagnosis was established for each of the 431 relatives blind to family data. Age-corrected morbidity risks were calculated using the life-table method. RESULTS: Relatives of cycloid psychotic patients showed a significantly lower morbidity risk for endogenous psychoses in general and manic-depressive illness compared to relatives of patients with manic-depressive illness. The familial morbidity risk for cycloid psychoses was low and did not differ significantly in both proband groups. Relatives of cycloid psychotic patients however did not differ significantly from relatives of controls regarding familial morbidity. LIMITATIONS: Our time-consuming methodical procedure implicated a relatively small number of participants due to restricted personnel resources. The restriction to hospitalised probands could possibly cause a limited representativity of the study sample. CONCLUSIONS: Our results suggest that cycloid psychoses are aetiologically different from manic-depressive illness and could not be integrated into a spectrum of bipolar affective disorders. The findings provide further evidence for a nosological independence of cycloid psychoses.

[Folie à deux - mental infection or individual psychosis]. / Die Folie à deux - Psychische Ansteckung oder eigenständige Psychoseerkrankungen?

The phenomenon of folie à deux has been a topical issue in psychiatry for more than a century. Mainly, genetic and psychodynamic factors are discussed controversially in terms of their relevance to the etiology of folie à deux. In this paper, effort is taken to reconceive the topic applying the criteria of a differentiated psychopathological classification. Based on the literature and on two own cases, we try to elaborate characteristical psychopathological features of folie à deux patients. We hypothesize that at least a substantial fraction could be classified as "folie simultanée" when Leonhard's criteria of the affect-laden paraphrenia are considered.

[Cycloid psychoses as atypical manic-depressive disorders. Results of a family study]. / Sind zykloide Psychosen atypische manisch-depressive Erkrankungen? Ergebnisse einer Familienuntersuchung.

BACKGROUND: Whereas a growing body of evidence suggests that cycloid psychoses have to be separated from schizophrenic psychoses, their relations to bipolar affective disorder are less clear. PATIENTS AND METHODS: In a controlled family study, we recruited 46 patients with cycloid psychosis (CP), 33 with manic-depressive illness (MDI), and 27 controls. Three hundred fifty-six of 389 living first-degree relatives were personally examined by experienced psychiatrists blinded to the diagnosis of the index proband. RESULTS: The relatives of CP patients showed significantly lower morbidity risk of functional psychoses than relatives of patients with MDI in Kaplan-Meier life table calculation. The morbidity risk for functional psychoses in relatives of patients with CP did not differ significantly from that in relatives of controls. CONCLUSION: These results suggest that CP are etiologically different from bipolar affective psychoses and cannot be integrated into the spectrum of bipolar affective disorders. The findings provide further evidence for a nosological independence of CP.

[Kleptomania: clinical and legal aspects]. / Kleptomanie: klinische und forensische Aspekte.

Kleptomania is characterized by repetitive and irresistible impulses to steal objects, with growing excitement before, and relief after the incidents. The thefts are not planned, carried out without confidants and regarded as illegal by the offenders who often feel guilty for it. The objects are stolen not for monetary gain or personal use, but are mostly discarded, given away or hoarded. Though there is a debate going on for more than 100 years, the nosological position of kleptomania remains unclear. On the one hand the clinical picture is observed as an isolated disorder in otherwise healthy persons, on the other hand it may also occur as an accompanying symptom of various other psychiatric disorders, e. g. impulse control disorders, acute psychoses, affective, or organic psychic disorders. The present article gives an overview of the most important aetiopathogenetic viewpoints about kleptomania and discusses their nosological, therapeutical and legal implications.

Differences in substantia nigra echogenicity of nosological subtypes within the schizophrenic spectrum. A preliminary transcranial ultrasound study.

OBJECTIVE: Schizophrenic patients treated with neuroleptic drugs often develop neuroleptic-induced parkinsonism (NIP). Here, transcranial sonography (TCS) was used to test for differences in the susceptibility to NIP related to the echogenicity of the substantia nigra (SN) in different schizophrenic subforms. METHODS: 79 patients with schizophrenic spectrum psychoses treated by neuroleptic drugs and diagnosed according to ICD-10 and Leonhard's nosology were examined independently by TCS and, clinically, for NIP. RESULTS: Patients with larger echogenic SN had more severe NIP (p < 0.05). Diagnostic categories according to ICD-10 did not differ significantly in SN echogenicity (p > 0.2), whereas Leonhard's did (p < 0.05). CONCLUSIONS: These findings suggest altered SN echogenicity in subtypes of the schizophrenic spectrum. The putative role of the nigrostriatal system in the etiology of schizophrenic subtypes is discussed.

Cycloid psychoses -- from clinical concepts to biological foundations.

The modern concept of cycloid psychoses is primarily based upon the clinical delineation of their phenotypes according to Leonhard. By settling the dilemma of Kraepelinean "atypical psychoses", their description may be considered one of the major achievements of clinical psychiatry in the last century. In particular, this had been facilitated by the work of Wernicke and Kleist. Albeit not yet generally recognized, cycloid psychoses have already stimulated great efforts of research yielding remarkable results. In this article, we elucidate the concept of cycloid psychoses and present recent findings pertaining to their putative biological foundations. Finally, future perspectives for the field of biological psychiatry are proposed fostering the heuristics of Leonhard's nosology.

[Hypochondriacal euphoria as a special form of monopolar affective psychosis]. / Die hypochondrische Euphorie als Sonderform einer monopolaren affektiven Psychose.

BACKGROUND: In contemporary concepts of affective psychoses the existence of monopolar manias is widely questioned. Nevertheless, cases of manias with monomorphous symptomatology are reported repeatedly from all over the world. Based upon subtle observation of signs and course over many years, Karl Leonhard developed a concept of affective psychoses that permits a distinction of monopolar from bipolar forms, e.g. monopolar manias and euphoric euphorias. METHODS: As an example for the pure forms of euphorias we present two cases of hypochondriacal euphoria. CONCLUSION: We discuss some of the literature relevant to the issue and propose the application of a differentiated psychopathological analysis for the discrimination of monopolar from bipolar manias.

[Comparative study of life quality in patients with cycloid and schizophrenic psychoses]. / Vergleichsuntersuchung zur Lebensqualität bei Probanden mit zykloiden und schizophrenen Psychosen.

BACKGROUND: Cycloid psychoses represent a nosological entity not adequately recognised by contemporary psychiatry. They show full recovery after each episode and thus have a favourable prognosis. METHODS: Course, psychiatric status, social function, and quality of life (QoL) of 33 patients with cycloid psychosis and 44 schizophrenics were compared (CGI, PANSS, GAF, Strauss-Carpenter,WHOQOL-BREF).Also, 48 controls were asked to rate their QoL. RESULTS: The schizophrenics developed symptoms earlier in life (P=0.009) and were hospitalized longer (P=0.001) and more frequently(P=0.01) than patients with cycloid psychosis. The latter showed better scores in the applied scales (P<0.0001). In QoL measures, cycloid psychotic patients were more satisfied than schizophrenic patients in three of four domains(P<0.01). Only in one domain did they differ from controls (P<0.01). CONCLUSION: Cycloid psychoses display better course, outcome, and QoL than schizophrenia.Thus, they appear to present a useful concept deserving more clinical and scientific attention.
