Further treatment with clozapine is contraindicated in any patient who has previously experienced leucopenia or neutropenia during clozapine therapy.

To investigate the results of such a rechallenge in 53 patients.

An analysis was made of the demographic, haematological and outcome data of patients in the UK and Ireland who were rechallenged with clozapine following leucopenia or neutropenia during previous clozapine therapy.

Of 53 patients who were rechallenged, 20 (38%) experienced a further blood dyscrasia. In 17 of these 20 patients (85%) the second blood dyscrasia was more severe(P<0.001), in 12(60%) it lasted longer (P=0.0368) and in 17 (85%) it occurred more quickly on rechallenge (P<0.001). Of the original 53 patients, 55% (29 patients) are still receiving clozapine.

No clear risk factor for repeat blood dyscrasias was identified. Despite this, after risks and benefits have been considered, rechallenge may well be justified in some patients.

We set out to investigate whether community nurses could be trained in problem-solving therapy and, once trained, how effective they would be in treating emotional disorders in primary care.

Seventy patients with an emotional disorder in primary care were randomly allocated to receive either problem-solving therapy from a trained community nurse or treatment as usual from their general practitioner. Interview and self-rated assessments of clinical and economic outcome were made pre-treatment, at eight weeks and at 26 weeks after treatment.

There was no difference in clinical outcome between patients who received problem-solving treatment and patients who received the general practitioner's usual treatment. However, patients who received problem-solving treatment had fewer disability days and fewer days off work. The health care cost of problem-solving was greater than that of the general practitioner's usual treatment but this was more than offset by savings in the cost of days off work.

Problem-solving treatment can be given by trained community nurses. The clinical effectiveness and cost-benefit of the treatment will depend on the selection of appropriate patients.

Few studies have addressed the relationship between generalised anxiety disorder and cardiovascular prognosis using a diagnostic interview.

To assess the association between generalised anxiety disorder and adverse outcomes in patients with myocardial infarction.

Patients with acute myocardial infarction (n = 438) were recruited between 1997 and 2000 and were followed up until 2007. Current generalised anxiety disorder and post-myocardial infarction depression were assessed with the Composite International Diagnostic Interview. The end-point consisted of all-cause mortality and cardiovascular-related readmissions.

During the follow-up period, 198 patients had an adverse event. Generalised anxiety disorder was associated with an increased rate of adverse events after adjustment for age and gender (hazard ratio: 1.94; 95% confidence interval: 1.14–3.30; P = 0.01). Additional adjustment for measures of cardiac disease severity and depression did not change the results.

Generalised anxiety disorder was associated with an almost twofold increased risk of adverse outcomes independent demographic and clinical variables and depression.

Outcomes reflecting the social situation are widely considered as important in the treatment of people with schizophrenia

To review concepts of social outcomes in schizophrenia and the corresponding assessment instruments

Non-systematic literature review and reflection on conceptual and methodological issues

Concepts of social outcomes in schizophrenia lack agreed definitions and theoretical models. A fundamental issue is the distinction between objective and subjective indicators. More research has focused on subjective indicators, which are only weaklly correllated with objective life situation and show consistent correlations with mood. Various assessment instruments have been developed pragmatically, particularly to measure quality of life and social functioning, and the literature provides extensive data for comparison

Established instruments exist to measure social outcomes in schizophrenia. Their use requires an awareness of the specific strengths and limitations

The neurocognitive basis of auditory hallucinations is unclear, but there is increasing evidence implicating abnormalities in processing inner speech. Previous studies have shown that people with schizophrenia who were prone to auditory hallucinations demonstrated attenuated activation of brain areas during the monitoring of inner speech.

To investigate whether the same pattern of functional abnormalities would be evident as the rate of inner speech production was varied.

Eight people with schizophrenia who had a history of prominent auditory hallucinations and eight control participants were studied using functional magnetic resonance imaging while the rate of inner speech generation was varied experimentally.

When the rate of inner speech generation was increased, the participants with schizophrenia showed a relatively attenuated response in the right temporal, parietal, parahippocampal and cerebellar cortex.

In people with schizophrenia who are prone to auditory hallucinations, increasing the demands on the processing of inner speech is associated with attenuated engagement of the brain areas implicated in verbal self-monitoring.

Stereotactic subcaudate tractotomy (SST) is the only type of psychosurgery performed at the Geoffrey Knight Unit, London, where nearly 1300 operations have been done since 1961. Statistically reliable data are not available to prove the effectiveness of SST. A detailed statement about contemporary psychosurgery is given.

Relevant publications from the Unit and via Medline are discussed. The outcome figures are reviewed. The outcome is assessed at the Unit in global and clinical terms, associated with results of self-completed questionnaires.

ST allows 40–60% of patients to live normal or near-normal lives, perhaps with continuation of medication. A reduction in suicide rate to 1% postoperatively, from 15% in cases of uncontrolled affective disorders is seen.

As a treatment of last resort, no controlled trial against a comparable treatment is possible. It appears reasonable to offer SST to patients with suicidal and deluded depression or with frequently swinging moods, not responding to other treatments.

The safety of antidepressants in children and adolescents is being questioned and the efficacy of these drugs in juvenile depression remains uncertain

To assess antidepressant efficacy in juvenile depression

Systematic review and meta-analysis of randomised controlled trials (RCTs) comparing responses to antidepressants, overall and by type, v. placebo in young people with depression

Thirty drug-placebo contrasts in RCTs lasting 8 weeks (median) involved 3069 participants (512 person-years) of average age 13.5 years. Meta-analysis yielded a modest pooled drug/placebo response rate ratio (RR=1.22, 95% CI 1.15–1.31), with little separation between antidepressant types. Findings were similar for response rate differences and corresponding number needed to treat (NNT): overall NNT=9; tricyclic antidepressants NNT=14 > serotonin reuptake inhibitors NNT=9 > other antidepressants NNT=8. Numbers needed to treat decreased with increasing age: children (NNT=21) > mixed ages (NNT=10) > adolescents (NNT=8)

Antidepressants of all types showed limited efficacy in juvenile depression, but fluoxetine might be more effective, especially in adolescents. Studies in children and in severely depressed, hospitalised or suicidal juvenile patients are needed, and effective, safe and readily accessible treatments for juvenile depression are urgently required

123I-FP-CIT SPECT (single photon emission computed tomography) can help in the differential diagnosis of probable dementia with Lewy bodies (Lewy body dementia) and Alzheimer's disease.

Our aim was to determine the accuracy of 123I-FP-CIT SPECT in diagnosing people with possible dementia with Lewy bodies.

We undertook a 12-month follow-up of 325 individuals with probable or possible Lewy body or non-Lewy body dementia who had previously undergone 123I-FP-CIT SPECT. A consensus panel masked to SPECT findings, established diagnosis at 12 months in 264 people.

Of 44 people with possible dementia with Lewy bodies at baseline, at follow-up the diagnosis for 19 people was probable dementia with Lewy bodies (43%), in 7 people non-Lewy body dementia (16%) and for 18 individuals it remained possible dementia with Lewy bodies (41%). Of the 19 who at follow-up were diagnosed with probable dementia with Lewy bodies, 12 had abnormal scans at baseline (sensitivity 63%); all 7 individuals with a possible diagnosis who were diagnosed as having Alzheimer's disease at follow-up had normal scans (specificity 100%).

Our findings confirm the diagnostic accuracy of 123I-FP-CIT SPECT in distinguishing Lewy body from non-Lewy body dementia and also suggest a clinically useful role in diagnostically uncertain cases, as an abnormal scan in a person with possible dementia with Lewy bodies is strongly suggestive of dementia with Lewy bodies.

Self-management is intended to empower individuals in their recovery by providing the skills and confidence they need to take active steps in recognising and managing their own health problems. Evidence supports such interventions in a range of long-term physical health conditions, but a recent systematic synthesis is not available for people with severe mental health problems.

To evaluate the effectiveness of self-management interventions for adults with severe mental illness (SMI).

A systematic review of randomised controlled trials was conducted. A meta-analysis of symptomatic, relapse, recovery, functioning and quality of life outcomes was conducted, using RevMan.

A total of 37 trials were included with 5790 participants. From the meta-analysis, self-management interventions conferred benefits in terms of reducing symptoms and length of admission, and improving functioning and quality of life both at the end of treatment and at follow-up. Overall the effect size was small to medium. The evidence for self-management interventions on readmissions was mixed. However, self-management did have a significant effect compared with control on subjective measures of recovery such as hope and empowerment at follow-up, and self-rated recovery and self-efficacy at both time points.

There is evidence that the provision of self-management interventions alongside standard care improves outcomes for people with SMI. Self-management interventions should form part of the standard package of care provided to people with SMI and should be prioritised in guidelines: research on best methods of implementing such interventions in routine practice is needed.

Neuroanatomical abnormalities are a well-established feature of schizophrenia. However, the timing of their emergence and the extent to which they are related to vulnerability to the disorder as opposed to psychotic illness itself is unclear

To assess regional grey matter volume in the at-risk individuals who subsequently developed psychosis

Magnetic resonance imaging data from at-risk individuals who developed psychosis (n = 12) within the following 25 months were compared with data from healthy volunteers (n=22) and people with first-episode psychosis (n=25)

Compared with healthy volunteers, individuals who subsequently developed psychosis had smaller grey matter volume in the posterior cingulate gyrus, precuneus, and paracentral lobule bilaterally and in the left superior parietal lobule, and greater grey matter volume in a left parietal/posterior temporal region. Compared with first-episode patients, they had relatively greater grey matter volume in the temporal gyrus bilaterally and smaller grey matter volume in the right lentiform nucleus

Some of the structural brain abnormalities in individuals with an at-risk mental state may be related to an increased vulnerability to psychosis, while others are associated with the development of a psychotic illness

The relationships between personality disorders and suicide were investigated among two aboriginal groups and the Han Chinese in East Taiwan.

Biographical reconstructive interviews were conducted for consecutive suicides from each of the three ethnic groups (116 suicides in total), 113 of whom were matched with two controls for age, gender, and area of residence.

In all three groups, a high proportion of suicides suffered from ICD-10 personality disorder before suicide (46.7–76.7%), and the most prevalent category was emotionally unstable personality disorder (F60.3) (26.7–56.7%). The risk for suicide was mainly significantly associated with F60.3, comorbidity among personality disorders, and comorbidity of personality disorder with other psychiatric disorders, particularly severe depression.

The main category of personality disorder significantly associated with the risk of suicide is F60.3 in ICD-10. The risk is highest for a comorbidity of this category and severe depression.

Past episodes of depressive or anxiety disorders and subthreshold symptoms have both been reported to predict the occurrence of depressive or anxiety disorders. It is unclear to what extent the two factors interact or predict these disorders independently.

To examine the extent to which history, subthreshold symptoms and their combination predict the occurrence of depressive (major depressive disorder, dysthymia) or anxiety disorders (social phobia, panic disorder, agoraphobia, generalised anxiety disorder) over a 2-year period.

This was a prospective cohort study with 1167 participants: the Netherlands Study of Depression and Anxiety. Anxiety and depressive disorders were determined with the Composite International Diagnostic Interview, subthreshold symptoms were determined with the Inventory of Depressive Symptomatology–Self Report and the Beck Anxiety Inventory.

Occurrence of depressive disorder was best predicted by a combination of a history of depression and subthreshold symptoms, followed by either one alone. Occurrence of anxiety disorder was best predicted by both a combination of a history of anxiety disorder and subthreshold symptoms and a combination of a history of depression and subthreshold symptoms, followed by any subthreshold symptoms or a history of any disorder alone.

A history and subthreshold symptoms independently predicted the subsequent occurrence of depressive or anxiety disorder. Together these two characteristics provide reasonable discriminative value. Whereas anxiety predicted the occurrence of an anxiety disorder only, depression predicted the occurrence of both depressive and anxiety disorders.
