Background. Orthotopic heart transplantation (OHT) is a major surgical intervention inducing distress and anxiety. Psychiatric evaluation of organ transplant candidates is now routinely proposed. This study purposed to assess the psychological evolution in patients having received psychological and/or psychiatric assistance before and during 1–6 postoperative months. Methods. Twenty-two consecutive transplant candidates were psychically evaluated as part of the preoperative protocol. In the waiting period, 1 and 6 months after OHT, they were asked to fill out the following questionnaires: the General Health Questionnaire, the Spielberger’s State-Trait Anxiety Inventory, the Beck Depression Inventory, the Perceived Social Support Scale, the Toronto Alexithymia Scale and the Personal Reaction Inventory. Results. A DSM-IV Axis I diagnosis was found in nine patients (41%); four patients (18%) presented with an Axis II diagnosis. One month after OHT, scores of depression, anxiety and general health significantly improved, while scores of social support, alexithymia and social desirability did not differ. In the sixth postoperative month, all psychological scores remained stable. Conclusions. A high prevalence of preoperative psychopathology was reported in 22 candidates who received OHT. Surgical intervention obviously improved the quality of life after cardiac transplantation. If the impact of psychological and/or psychiatric aid remains difficult to appraise, these results emphasize the positive impact of surgery on psychological status and the appropriateness of the psychosomatician’s social support intervention on patients facing the transplant process.

The aim of this study is to describe the situation of Spanish obsessive-compulsive disorder (OCD) patients and compare it to that of the general population and other patient groups.

There is a tension between the need for scientifically valid trials of new psychotropic drugs and concern about conducting placebo-controlled trials, the trials psychopharmacologists consider the gold standard trial, when this requires that some patients be denied existing effective therapy. This paper will review the scientific principles supporting the need for placebo-controlled trials in depression and schizophrenia, and will provide preliminary data on failure rates of placebo-controlled trials for these disorders, as illustrations of the application of these principles. Next, the ethical issues pertinent to the conduct of placebo-controlled trials for these two serious psychiatric disorders will be reviewed. Preliminary data on suicides in placebo-controlled depression and schizophrenia trials will be presented to argue for the ethical acceptability of the conduct of placebo-controlled trials in these two conditions.

Animal models are often used for preclinical research on the neurobiology of psychiatric disorders. Whereas many are employed to screen new therapeutic agents, few of them are used to study the genetic bases of psychiatric diseases, probably because of the complex genetic determinism underlying quantitative behavioral traits such as mood, personality or intelligence. The present article presents a short review introducing an analysis model using mi the marker strains model. Using this model it is possible both to display genetic determinism data and to locate some of the chromosomal fragments involved in the regulation of anxiogenic processes. At present it cannot accurately determine the position of one or more genes, but it does provide a valuable means of ‘scanning’ the genome for an approximation. Through genetic analysis, using the model, an attempt will be made to identify autosomal fragments which may be involved in two behavioural traits: anxiety and chemical-induced seizures. In this paper, after reviewing theoretical aspects of looking for genes involved in behaviour, we will successively introduce studies in genetic topics in psychiatric human studies as well as appropriated behavioural animal studies. Then we will present a genetic model in mice which allows us to locate chromosomal fragments associated with a behavioural trait: multiple marker strains.

Studies on the enhancing effects of nicotine on performance are usually pharmacological challenges using deprived male smokers. However, gender may be a factor that influences nicotine/smoking effects upon information processing. We investigated gender differences in contingent negative variation (CNV) amplitude in non-deprived dependent smokers performing a go-no go reaction time paradigm. Female smokers did not differ from female non-smokers in both early and late CNV, whereas male smokers presented greater early and late CNV compared to male non-smokers and an alteration in inhibiting processes responsible for CNV development in the no go condition. Consistent with the evidence of gender differences in nicotine/smoking sensitivity, these preliminary results emphasize the need for taking into account gender in psychophysiological research of nicotine/smoking effects.

Sexual function following 3,4-Methylenedioxymethamphetamine (MDMA, or ‘Ecstasy’) consumption was subjectively evaluated in 35 healthy recreational users (20 men and 15 women, aged 21–48 years) with regard to four major domains of sexual activity: desire, erection (lubrication in women), orgasm and satisfaction. Desire and satisfaction were moderately to profoundly increased by MDMA in more than 90% of subjects. Orgasm was delayed but perceived as more intense. Erection was impaired in 40% of the men. It seems that MDMA impairs sexual performance, in spite of enhancement of sexual desire and the perception of greater satisfaction.

Several data are available about the implication of the dopaminergic system in the control of inward-directed aggression. Previously, we suggested an involvement of D2-dopaminergic function in the expression of suicidal behavior by demonstrating a smaller growth hormone (GH) response to apomorphine, a dopaminergic agonist, in depressed patients with a history of suicide attempts in comparison to non-attempters. In the present study, in order to test this hypothesis, GH responses to intravenous apomorphine were measured in non-depressed patients with a history of suicide attempts. The study was performed in 17 non-depressed male patients with a score less than 12 on the 17-item HAMD. The patients were subgrouped into suicide attempters (N = 7) and non-attempters (N = 10). Mean GH peak responses to apomorphine differed significantly between suicide attempters and non-attempters: (mean ± SD) for GH peak, 10.4 ± 8.2 ng/mL vs 27.3 ± 13.1 ng/ml, F = 9.0, P = 0.009. In conclusion, dopaminergic disturbances seem to play a role in the biology of inward-directed aggression in non-depressed patients.

Topiramate is an antiepileptic agent, which is being investigated as a mood-stabilizer. Three obese individuals with DSM-IV bipolar I disorder and type II diabetes mellitus received topiramate treatment in combination with antipsychotics and valproate or carbamazepine. In addition to improved mood stability, these individuals lost between 16 to 20.5% of their pre-topiramate body weight and also achieved significant glycemic control.

Twenty-four chronic schizophrenic outpatients with a mean age of 37.21 years ± 9.96 SD were treated with risperidone (RSP) at the dosage of 2–9 mg/die (mean 4.46 mg/die ± 1.30 SD, mean 0.06 mg/kg ± 0.01 SD) for a year.

Clinical evaluation was assessed with the Brief Psychiatric Rating Scale (BPRS), Positive and Negative Symptoms Scale (PANSS), Extrapyramidal Side Effects Rating Scale (EPSE) and a checklist for Anticholinergic Side Effects (ACS) at T0, then after 1 (T1), 2 (T2), 3 (T3), 6 (T6), 9 (T9) and 12 (T12) months. RSP and 9-hydroxy-risperidone (9OH-RSP) plasma levels were determined at T12 by the HPLC method. BPRS and PANSS mean values showed a significant improvement during the study. No correlation between RSP dosage (mg/kg) and RSP, 9OH-RSP plasma levels or active moiety resulted. A positive correlation between age and active moiety was observed. A positive correlation between RSP and 9OH-RSP plasma levels was observed. A curvilinear relationship between active moiety and PANSS improvement (%) was observed. Patients with the higher PANSS amelioration showed RSP + 9OH-RSP plasma levels ranging from 15 to 30 ng/mL. RSP seems to be quite an effective drug. It seems, however, difficult to devise appropriate dose schedules and plasma level determination seems to be necessary in some cases.

We assessed whether cytokine production–interleukin (IL)-1β, IL-6 and tumour necrosis factor-α (TNFα)–is affected in depressed patients, dysthymia (Dt) and major depression (MD), and its association with various parameters of severity and clinical course. We found a possible different pattern of interleukin production between Dt and MD.

The suicide attempts were assessed in 32 schizophrenic patients on whom the dexamethasone suppression test (DST) was done twice in the course of illness: in the years 1985–91 and 1996–97. In the 1985–91 period, both baseline and post-dexamethasone cortisol levels were significantly higher in the patients with previous suicide attempts and baseline cortisol was higher in the patients who were to make a future attempt. In 1996–97, DST non-suppression was shown in more than half of the patients with a history of suicide attempt and in none of those without such history: all cortisol levels were significantly higher in the patients with a history of suicide attempt. Although the mean intensity of depression was higher in the patients with a history of suicide attempt, no association between the intensity of depression and present or previous DST non-suppression status was found. It is suggested that the hyperactivity of the hypothalamic-pituitary-adrenal axis may constitute an element of diathesis for suicidal behavior in schizophrenic patients.

A case is presented in which severe urinary retention (UR) occurred during an acute psychotic exacerbation of paranoid schizophrenia. The voiding dysfunction was apparent during continuous treatment with unchanged doses of haloperidol, and it completely resolved with the remission of the psychotic symptoms. A clear temporal correlation was evident between the patient’s mental status, the Brief Psychiatric Rating Scale (BPRS) score and the degree of the UR as assessed by quantitatively measuring the total daily postvoiding urine residues. We could not relate the UR to any apparent general medical condition or to the haloperidol treatment. The presented data suggests that UR in schizophrenic patients might be the end-result of various psychosis-related mechanisms.

Twenty-two female psychiatric outpatients with experiences of childhood sexual abuse took part in a two-year group therapy. All completed therapy. At the end of therapy the women’s psychiatric symptoms were reduced and their social interaction and adjustment were improved. They evaluated relationships to their children, partners and friends to be improved.

A client satisfaction survey was undertaken in two adult psychiatric outpatient clinics. The anonymous self-report questionnaire covering demographic, setting and satisfaction with service variables was endorsed by 203 participants. The mean age of the subjects was 42.5 ± 19 years, with a small majority (58.6%) of females. Overall satisfaction with psychiatric care was high (79.8%). None of the demographic or setting variables correlated significantly with satisfaction. Psychoeducation was significantly correlated with level of satisfaction with services. These findings further emphasize the importance of psychoeducation by service providers in mental health.
