AIMS AND METHODWe aimed to determine, using clinical audit, the effect of implementing national guidelines on the quality of responsible medical officers' (RMOs’) reports to the mental health review tribunal (MHRT). We blindly assessed the quality of 50 consecutive reports concerning patients detained under Sections 3 and 37. Twenty-five reports were written before guidelines were circulated; a further 25 were written following the distribution of guidelines and a checklist with every request for a report.RESULTSThe quality of reports, as measured by our checklist, significantly improved following the circulation of guidelines.CLINICAL IMPLICATIONSIncreasing the awareness of guidelines by widespread circulation and the audit process is an effective way of improving the quality of RMOs' reports to the MHRT.

Difficulty with social interactions is a characteristic of schizophrenia. The authors used functional magnetic resonance imaging (fMRI) to investigate brain activation changes during a social cognition paradigm in patients with schizophrenia during and after an acute episode and their association with social and executive function.In a longitudinal study design, 14 patients with schizophrenia experiencing an acute episode had an fMRI scan. They returned for a follow-up scan after clinical improvement. Fourteen healthy comparison subjects were also scanned twice with approximately the same time interval between scans as in the patient group. The authors employed a social cognition fMRI paradigm involving empathic and forgivability judgments. Schizophrenia symptoms, social functioning and illness insight scales, and the Wisconsin Card Sorting Test were used to examine whether improvement on these measures was associated with recovery of brain activation in response to the social cognition paradigm.After recovery from the acute episode, patients exhibited increased activation in the left medial prefrontal cortex, which was, in turn, significantly correlated with improved insight and social functioning. Decreased symptom severity and improved performance on the Wisconsin Card Sorting Test were not significantly associated with increased left medial prefrontal cortex activation.This is the first study to the authors' knowledge to use a social cognition paradigm to reveal improved left medial prefrontal cortex activation in schizophrenia after recovery from an acute episode. These results suggest that restored left medial prefrontal cortex activation may mediate improvement of insight and social functioning in patients with schizophrenia.

We aimed to investigate cerebellar structural abnormalities and their functional significance in patients with schizophrenia. Forty right-handed men with schizophrenia and 40 sex, age and handedness matched controls underwent a volumetric magnetic resonance scan with 1 mm3 isotropic spatial resolution. Cerebellar grey- and white-matter volumes were analysed using voxel-based morphometry. Patients with schizophrenia completed a battery of neuropsychological tests assessing sustained attention (continuous performance test), memory (Hopkins memory test) and executive function (verbal fluency and Wisconsin card sorting tests). Patients with schizophrenia exhibited significantly increased cerebellar vermis white-matter volume compared with controls. By contrast, total cerebellar volume, and grey- and white-matter volumes of cerebellar hemispheres were not significantly different between groups. Increased vermis white-matter volume in patients was associated with poor verbal fluency performance. We concluded that increased white-matter in the cerebellar vermis, possibly suggesting anomalous connectivity, may be associated with verbal executive dysfunction in men with chronic schizophrenia.
