- Tobacco smoking is common among psychiatric patients, especially among those with schizophrenia, where the prevalence is extremely high, 74% to 88%, compared with 45% to 70% in patients with other psychiatric diagnoses. Patients with anxiety disorders are less well investigated in this respect, particularly obsessive-compulsive disorder (OCD) patients. Eighty-three psychiatric outpatients with OCD and 110 members of the Swedish OCD Association responded to questions concerning their smoking habits. Among OCD patients, 14% were current smokers (compared with 25% in the general population of Sweden), 72% had never smoked, and 11 previous smokers had stopped, mostly without any difficulties. Since a decreased smoking rate among OCD subjects was confirmed, the smoking prevalences in schizophrenia and OCD, respectively, seem to represent either end of a continuum, and OCD may also differ significantly from other anxiety disorders in this respect. Possible implications of this finding for the purported frontal lobe dysregulation in OCD are discussed.

- The Temperament and Character Inventory (TCI) is a self-report personality questionnaire based on Cloninger's psychobiological model of personality, which accounts for both normal and abnormal variation in the two major components of personality, temperament and character. Normative data for the Swedish TCI based on a representative Swedish sample of 1,300 adults are presented, and the psychometric properties of the questionnaire are discussed. The structure of the Swedish version replicates the American version well for the means, distribution of scores, and relationships within the between scales and subscales. Further, the Swedish inventory had a reliable factor structure and test-retest performance. The results of this study confirm the theory of temperament and character as a seven-factor model of personality.

- BACKGROUND: Various approaches have been made over the years to classify psychotic patients according to inadequate treatment response, using terms such as treatment resistant or treatment refractory. Existing classifications have been criticized for overestimating positive symptoms; underestimating residual symptoms, negative symptoms, and side effects; or being to open for individual interpretation. The aim of this study was to present and evaluate a new method of classification according to treatment response and, thus, to identify patients in functional remission. METHOD: A naturalistic, cross-sectional study was performed using patient interviews and information from patient files. The new classification method CANSEPT, which combines the Camberwell Assessment of Need rating scale, the Udvalg for Kliniske Undersøgelser side effect rating scale (SE), and the patient's previous treatment history (PT), was used to group the patients according to treatment response. CANSEPT was evaluated by comparison of expected and observed results. RESULTS: In the patient population (n = 123), the patients in functional remission, as defined by CANSEPT, had higher quality of life, fewer hospitalizations, fewer psychotic symptoms, and higher rate of workers than those with the worst treatment outcome. CONCLUSION: In the evaluation, CANSEPT showed validity in discriminating the patients of interest and was well tolerated by the patients. CANSEPT could secure inclusion of correct patients in the clinic or in research.

Tidskriftsartikel (refereegranskat)abstract
- Background: Depressed suicide attempters are, according to some earlier studies, treated more often with antipsychotics than depressive non-suicide attempters. Cluster B personality disorders, especially borderline personality disorder, are associated with a high suicide risk, and antipsychotics are commonly used for the reduction of symptoms. However, no previous study has taken comorbid personality disorders into account when assessing the use of antipsychotics in patients with unipolar depression. Therefore, the aim of this study was to investigate the clinical selection of pharmacotherapy in unipolar depression with and without a previous suicide attempt, taking into account potential confounders such as cluster B personality disorders. Methods: The study sample consisted of 247 patients with unipolar depression. The study was approved by the Regional Ethical Review Board in Lund, Sweden. Study participants were recruited from 4 different secondary psychiatric care clinics in Sweden and were diagnosed according to the DSM-IV-TR with the MINI and SCID II. Previous and ongoing psychiatric treatments were investigated in detail and medical records were assessed. Results: Thirty percent of the patients had made previous suicide attempts. Depressed suicide attempters underwent both lifetime treatment with antipsychotics and an ongoing antipsychotic treatment significantly more often than non-attempters. Significances remained after a regression analysis, adjusting for cluster B personality disorders, symptom severity, age at the onset of depression, and lifetime psychotic symptoms. Conclusions: This is the first study to consider the effect of comorbidity with cluster B personality disorders when comparing treatment of depressive suicide and non-suicide attempters. Our findings suggest that suicide attempters are more frequently treated with antipsychotics compared to non-suicide attempters, regardless of cluster B personality disorder comorbidity. These findings are important for clinicians to consider and would also be relevant to future studies evaluating reduction of suicide risk with antipsychotics in patients with psychiatric comorbidity and a history of attempted suicide.

- Background: Body dysmorphic disorder (BDD) is characterized by a highly distressing and impairing preoccupation with nonexistent or slight defects in appearance. Patients with BDD present to both psychiatric and non-psychiatric physicians. A few studies have assessed BDD prevalence in representative samples of the general population and have demonstrated that this disorder is relatively common. Our primary objective was to assess the prevalence of BDD in the Swedish population because no data are currently available. Methods: In the current cross-sectional study, 2891 randomly selected Swedish women aged 18-60 years participated. The occurrence of BDD was assessed using the Body Dysmorphic Disorder Questionnaire (BDDQ), which is a validated self-report measure derived from the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria for BDD. In addition, symptoms of depression and anxiety were measured using the Hospital Anxiety and Depression Scale (HADS). Results: The prevalence of BDD among Swedish women was 2.1%. The women with BDD had significantly more symptoms of depression and anxiety than the women without BDD. Depression (HADS depression score greater than= 8) and anxiety (HADS anxiety score greater than= 8) were reported by 42% and 72% of the women with BDD, respectively. Conclusions: The results of the present study indicate that BDD is relatively common among Swedish women (2.1%) and that it is associated with significant morbidity.

- OBJECTIVE: Earlier general population studies have shown that novelty seeking (NS) of the Temperament and Character Inventory (TCI) of personality is lower for persons born in winter compared to those born in summer, particularly for women. Here, we investigate if this result can be replicated in another population. METHOD: The Northern Finland 1966 Birth Cohort, comprising 4968 subjects (2725 women, 2243 men), was investigated with regard to the temperament dimensions of the TCI and the season of birth. RESULTS: Novelty seeking and reward dependence (RD) showed significant variations according to the month of birth. We found that women born during winter have significantly lower levels of NS compared to women born during summer, with a minimum for the birth month November and maximum for May. These results are similar to those found in a previous Swedish study. Furthermore, our study showed that men born during spring had significantly lower mean scores of RD compared to men born during autumn, with a minimum for birth month March. This was in contrast to the Swedish study, where the minimum of RD was obtained for the birth month December. CONCLUSION: Women born in winter have lower NS as adults compared to women born in summer. Because NS is modulated by dopamine, this study gives further support to the studies in the literature that show that dopamine turnover for those born in winter is higher than for those born in summer.

- Background: Of interest to women's mental health, a wealth of studies suggests sex differences in nicotine addiction and treatment response, but their psychoneuroendocrine underpinnings remain largely unknown. A pathway involving sex steroids could indeed be involved in the behavioural effects of nicotine, as it was found to inhibit aromatase in vitro and in vivo in rodents and non-human primates, respectively. Aromatase regulates the synthesis of oestrogens and, of relevance to addiction, is highly expressed in the limbic brain.Methods: The present study sought to investigate in vivo aromatase availability in relation to exposure to nicotine in healthy women. Structural magnetic resonance imaging and two [11C]cetrozole positron emission tomography (PET) scans were performed to assess the availability of aromatase before and after administration of nicotine. Gonadal hormones and cotinine levels were measured. Given the region-specific expression of aromatase, a ROI -based approach was employed to assess changes in [11C]cetrozole non-displaceable binding potential.Results: The highest availability of aromatase was found in the right and left thalamus. Upon nicotine exposure, [11C]cetrozole binding in the thalamus was acutely decreased bilaterally (Cohen's d =-0.99). In line, cotinine levels were negatively associated with aromatase availability in the thalamus, although as non-significant trend.Conclusions: These findings indicate acute blocking of aromatase availability by nicotine in the thalamic area. This suggests a new putative mechanism mediating the effects of nicotine on human behaviour, particularly relevant to sex differences in nicotine addiction.

- OBJECTIVE: To investigate the recently defined Positive and Negative Syndrome Scale for Schizophrenia remission criteria in a naturalistic setting of psychotic patients; to identify causal factors that change remission status; and to validate the criteria against global indices of illness, cognitive functions, and social outcome. METHODS: This was a longitudinal naturalistic study of 162 patients, diagnosed with schizophrenia or schizophrenia-related psychotic disorders (mean illness duration, 11 years) and treated with risperidone at study entry. Symptoms, drug treatment, cognitive function, and social outcome were measured at baseline and annually for 5 years. Remission was constructed retrospectively with only indirect data on stability over time. RESULTS: At study entry, 40% of the patients with schizophrenia were in symptomatic remission, stabilizing between 55% and 60% after a few years. The need for hospitalization became less frequent over time; initially 31%, dropping to 7% by years 4 and 5. Many patients went in and out of remission. Remission was strongly associated with global indices of illness, with intact insight and with social outcome (except work/studies) but not with cognition or medication. CONCLUSIONS: In spite of certain weaknesses of the study, we may conclude that current definition of remission is primarily a symptomatic measure, covering a subset of symptoms, some of which are not schizophrenia-specific. Although the definition may be clinically relevant, we must be aware of the risk that the connotation of the word could induce too much focus on symptom control.
