RESUMEN
BACKGROUND: Accumulating evidence suggests beneficial effects of media stories featuring individuals mastering their suicidal crises, but effects have not been assessed for psychiatric patients. METHODS: We randomized n = 172 adult psychiatric patients (n = 172, 97.1% inpatients) to read an educative article featuring a person mastering a suicidal crisis (n = 92) or an unrelated article (n = 80) in a single-blind randomized controlled trial. Questionnaire data were collected before (T1) and after exposure (T2) as well as 1 week later (study end-point, T3). The primary outcome was suicidal ideation as assessed with the Reasons for Living Inventory; secondary outcomes were help-seeking intentions, mood, hopelessness, and stigmatization. Differences between patients with affective versus other diagnoses were explored based on interaction tests. RESULTS: We found that patients with affective disorders (n = 99) experienced a small-sized reduction of suicidal ideation at 1-week follow up (mean difference to control group [MD] at T3 = -0.17 [95% CI -0.33, -0.03], d = -0.15), whereas patients with nonaffective diagnoses (n = 73) experienced a small-sized increase (T2: MD = 0.24 [95% CI 0.06, 0.42], d = 0.19). Intervention group participants further experienced a nonsustained increase of help-seeking intentions (T2: MD = 0.53 [95% CI 0.11, 0.95], d = 0.19) and a nonsustained deterioration of mood (T2: MD = -0.14 [95% CI -0.27, -0.02], d = -0.17). CONCLUSIONS: This study suggests that patients with affective disorders appear to benefit from media materials featuring mastery of suicidal crises. More research is needed to better understand which patient groups are at possible risk of unintended effects.

INTRODUCTION: From a clinical point of view, additional consumption of cocaine by methadone maintained patients seems to have increased during the last few years. In order to verify this clinical impression, we carried out a retrospective analysis about cocaine abuse by opioid-dependent patients undergoing methadone maintenance therapy at the drug addiction clinic, Department of Psychiatry, University of Vienna. METHODS: Supervised urinalysis was performed on a frequent basis in 160 patients during the investigational time frame of 1997 and 1999. Concomitant consumption of opioids, cocaine and benzodiazepines in urine toxicology results (n = 2242) was compared in a post hoc analysis. RESULTS: In 1997, 45% of urine toxicology tests were positive for opioids, 14.1% for cocaine and 22.1% for benzodiazepines. In 1999, however, 33.1% urine toxicology tests showed positive results for opioids, 22.2% for cocaine and 24% for benzodiazepines. It could be shown that the number of cocaine positive toxicology results increased significantly (p < 0.05) over the course of two years, and that the number of opioid positive tests decreased significantly (p < 0.05), whereas benzodiazepine consumption did not change. Age, and the duration of opioid dependence showed a significant influence on cocaine positive urinalysis. DISCUSSION: The significant increase of additional cocaine consumption in methadone maintained patients reflects the enhanced availability of the substance in Austria, as it has been shown in other European countries and the USA. In addition, evidence based treatment trials are needed to prove the efficacy of alternative opioid maintenance therapy and to evaluate whether cocaine consumption is less of a problem.

Based on recent quantitative EEG findings of increased slow activity in negative schizophrenia indicating organicity, it was hypothesized that neuroleptics decreasing delta/theta activity should be beneficial for schizophrenics with predominantly negative symptoms. Thus, a double-blind, clinical, psychometric and neurophysiological study was carried out in 40 hospitalized patients with unproductive schizophrenia (mean age: 31 years; ICD diagnoses: 295.0, 295.1 and 295.6) who were treated randomly either with the benzamide amisulpride (AMI; n = 19) or low doses of fluphenazine (FLU; n = 21). In the first 2 weeks the daily doses were 50 mg AMI or 2 mg FLU, respectively, from the third week on up to the sixth week 100 mg AMI and 4 mg FLU. Clinical evaluations, psychometry and EEG mapping were performed on day 1 (hours 0 and 4--acute effect), on day 14 (hour 0--subacute effect) and on day 42 (hours 0 and 4--chronic and superimposed effects). Three AMI patients discontinued therapy prematurely because of productive symptoms (days 14, 28 and 35), while in the FLU group 2 patients dropped out due to depressive symptoms (days 21, 28), 1 due to productive symptoms (day 35), 1 due to ineffectiveness (day 28), and 1 because of an akinetic crisis (day 6). Statistical evaluation demonstrated a significant improvement in the AMDP apathy and Andreasen SANS score in both groups with the patients remaining severely ill as rated by the CGI. FLU-treated patients needed significantly more anticholinergic medication than the AMI-treated group. Psychometric evaluation showed in regard to the noopsyche significant improvement after subacute, chronic and superimposed AMI, while FLU-treated patients showed significant improvement only after subacute treatment. AMI was significantly superior to FLU at the hours 0 and 4 of day 42. The thymopsyche improved after subacute, chronic and superimposed administration of both compounds with a significant superiority of AMI on days 14 and 42 (4 h postdrug). EEG mapping showed a decrease of delta/theta and increase of beta activity as well as an acceleration of the centroid after acute and superimposed AMI on day 42 as compared with baseline; FLU patients exhibited a decrease of delta/theta activity and an acceleration of the total centroid too, while alpha activity was augmented and beta activity tended to be reduced. Our study demonstrated that, in addition to the new benzamide AMI, FLU in low doses may also be regarded as a neuroleptic with activating properties and may be utilized in the treatment of schizophrenics with predominantly negative symptoms.

The premorbid psychosocial adjustment of 28 schizophrenic criminal offenders, 23 non-criminal-offender schizophrenics (ICD-9) and 14 nonpsychotic criminals was compared by means of the Premorbid Adjustment Scale (PAS). The schizophrenic groups did not differ regarding age, marital status, diagnostic subgroup or length of illness. PAS scores showed highly significant differences between the schizophrenic groups and the controls on every subscale and on average scores. Yet, aside from 2 items (sociability/withdrawal in adulthood and education), no differences could be found between offender and non-offender schizophrenics. Furthermore, the PAS scores showed a markedly better premorbid psychosocial adjustment in schizophrenics with offending behaviour (and convictions) before the onset of the psychosis than in schizophrenics without previous convictions, who committed one rather severe crime that was closely connected to psychosis itself.

The purpose of the present study is to visualize and quantify dopamine D2 receptors in the living human brain using an 123I-labeled ligand and the single photon emission computerized tomography (SPECT) technique. S-(-)-Iodobenzamide [S-(-)-IBZM] has been shown to be a highly selective ligand with high affinity for D2 receptors in experimental studies. Five millicuries (185 MBq) of 123I-labeled S-(-)-IBZM was administered intravenously to 12 control subjects, 22 parkinsonian patients under L-Dopa therapy, 12 parkinsonian patients without L-Dopa, 10 unmedicated patients with Huntington's disease, and 12 patients under different neuroleptics. Data collection with a rotating double-head scintillation camera started 1 h after injection and lasted for 50 min. In a semiquantitative approach, a ratio was calculated between mean counts per pixel in the striatum and a region in the lateral frontal cortex, which was 1.74 +/- 0.10 in the control group. A marked reduction of this ratio was found in patients with Huntington's disease (1.38 +/- 0.12; p = 0.0001), no significant changes in untreated parkinsonian patients (1.67 +/- 0.14), but a reduction in L-Dopa-treated cases (1.59 +/- 0.13; p = 0.0014). A curvilinear relationship was found between total daily dose of neuroleptics and the reduction of this ratio. Estimated receptor blockade under full neuroleptic treatment was 75-80%. S-(-)-IBZM binding was reduced with increasing age (p less than 0.01). Specific binding was reduced markedly when the racemic mixture of IBZM was used, and no specific binding was seen with the R-(+)-isomer, demonstrating the stereoselectivity of IBZM binding.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors investigated smooth pursuit eye movements (SPEMs) in 66 schizophrenic and 40 major affective patients and 39 healthy controls. The results showed significant differences of both patient groups as compared to the controls. Schizophrenics with neuroleptic treatment in the preceding 2 years were significantly more disturbed than the controls, the affective patients and the untreated schizophrenics. Acute neuroleptic medication and neuroleptic treatment of a duration of 4-6 weeks appear not to significantly influence the quality of SPEMs.

To follow up the status and further outcome of patients with recurrent affective and schizoaffective disorders treated in a lithium/prophylactic treatment outpatient (LOP) clinic the authors have developed a documentation system based on a database, which ASCII files. This system should be useful as a basis for optimal treatment and is helpful for special research purposes regarding prophylactic treatment (lithium salts, carbamazepine, antidepressants, etc.). The documentation system consists of two parts, one for routine documentation system consists of two parts, one for routine monitoring including basic data, global course, and routine form with side-effects, and another one for research purposes with documentation of laboratory findings, EEG, and documentation of every cycle which can be added easily. Moreover, with this documentation system it will be possible to compare results from different research centres.

This study is based on 20 healthy volunteers (10 males and 10 females). Between 675 and 1,225 mg lithium carbonate per day was applied for 10 days. EEG was recorded before (day 0) and after lithium intake (day 10) with 19 electrodes and quantified by spectrum analyses. Absolute power and coherence values, between adjacent electrodes and between electrodes on homologous sites of both hemispheres, were computed for five frequency bands. For the evaluation of differences of the EEG parameters obtained on days 0 and 10, a nonparametric paired permutation test was applied. The obtained descriptive error probabilities were presented in topographic maps. Under lithium, the absolute power increased in the entire frequency range, but most distinct in the theta and beta 1 band. The local coherence analyses revealed a clear lateralization: increase in the left hemisphere and decrease in the right. The interhemispheric coherence decreased occipitally and frontally. A comparison of the EEG changes under lithium in males and females showed clear differences in the topographic distribution of power as well as coherence changes.
