Abstract
Psychiatric acute units use different levels of segregation to satisfy needs for containment and decrease in sensory input for behaviourally disturbed patients. Controlled studies evaluating the effects of the procedure are lacking. The aim of the present study was to compare effects in acutely admitted patients with the use of a psychiatric intensive care unit (PICU) and not in a psychiatric acute department. In a naturalistic study, one group of consecutively referred patients had access only to the PICU, the other group to the whole acute unit. Data were obtained for 56 and 62 patients using several scales. There were significant differences in reduction of behaviour associated with imminent, threatening incidents (Broset Violence Checklist), and actual number of such incidents (Staff Observation Aggression Scale-Revised) in favour of the group that was treated in a PICU. The principles of patient segregation in PICUs have favourable effects on behaviours associated with and the actual numbers of violent and threatening incidents.

Abstract
To identify risk factors associated with cycle acceleration (CA), that is, progressive decrease in duration of syndrome-free intervals between affective episodes, in acutely admitted patients with bipolar disorder (BD).
All patients (n = 210) with BD I (67%) and BD II (33%) (DSM-IV) acutely admitted to a hospital serving a catchment area were compared in retrospect with regard to a positive or negative history of CA. Putative risk factors of CA with a P-value

Abstract
OBJECTIVE: Seasonal variations of violence have been the subject of some controversy. Norway, situated between latitudes 58 degrees and 72 degrees N, has considerable seasonal variations of light and provides a good opportunity for studies of seasonality. METHOD: The monthly numbers of police reports of violent incidents in 1991-1997 were obtained for the entire Norwegian population of 4,450,000 inhabitants and separately for each of seven Norwegian cities at different latitudes. RESULTS: A total of 82,537 episodes of violence were recorded. There was a significant variation in violent incidents between months, with a minimum daily frequency of 28.7 in March and a maximum daily frequency of 35.1 in June. The frequency curve had one significant peak in May through June and another significant peak in October through November. The monthly frequency of violence correlated with the absolute value of monthly change in length of day from the previous month. In the seven cities the highest monthly ratio of observed to expected frequencies increased with latitude. With increasing latitude, the months with the largest increase in violence came later both in the spring and in the fall. CONCLUSIONS: There is a distinct pattern of seasonal variation in the frequency of violence that varies systematically with latitude. This pattern resembles the seasonal pattern of some forms of suicide, hospitalization for affective disorders, and mood and activity in the general population.

Sleep problems in bipolar disorders: more than just insomnia.

Abstract
Sleep problems in bipolar disorder (BD) are common, but reported rates vary from 10% to 80%, depending on definitions, methodologies and management of potential confounding factors. This multicenter study seeks to address these issues and also compares BD cases with Hypersomnia as well as the more commonly investigated Insomnia and No Sleep Problem groups.
A cross-sectional comparison of sleep profiles in 563 BD I and II individuals who participated in a structured assessment of demographic, clinical, illness history and treatment variables.
Over 40% cases met criteria for Insomnia and 29% for Hypersomnia. In univariate analysis, Insomnia was associated with BD II depression whilst Hypersomnia was associated with BD I depression or euthymia. After controlling for confounders and covariates, it was demonstrated that Hypersomnia cases were significantly more likely to be younger, have BD I and be prescribed antidepressants whilst Insomnia cases had longer illness durations and were more likely to be prescribed benzodiazepines and hypnotics.
Whilst Insomnia symptoms are common in BD, Hypersomnia is a significant, frequently underexplored problem. Detailed analyses of large representative clinical samples are critical to extending our knowledge of differences between subgroups defined by sleep profile.
