    Input: OBJECTIVE The authors examined the efficacy of intramuscular flunitrazepam compared with intramuscular haloperidol for the immediate control of agitated or aggressive behavior in acutely psychotic patients . METHOD Twenty-eight actively psychotic in patients , aged 20 - 60 years , who were under treatment with neuroleptic agents were selected for the study . Each was r and omly assigned on a double-blind basis to receive either 5 mg i.m . of haloperidol ( N=13 ) or 1 mg i.m . of flunitrazepam ( N=15 ) during an aggressive event . Verbal and physical aggression was measured over time with the Overt Aggression Scale . Patients were also rated with the Brief Psychiatric Rating Scale and the Clinical Global Impression scale . RESULTS Both flunitrazepam and haloperidol exhibited acute antiaggressive activity . This beneficial effect , as assessed by the Overt Aggression Scale , was obtained within 30 minutes . CONCLUSIONS Intramuscular flunitrazepam may serve as a convenient , rapid , safe , and effective adjunct to neuroleptics in reducing aggressive behavior in emergency psychiatric setting Background Recent electroconvulsive therapy ( ECT ) efficacy studies of right unilateral ( RUL ) ECT may not apply to real life clinics with a wide range of patients with major depressive episodes . Methods The study included two groups of patients . In addition to a homogeneous group of patients with major depression according to DSM-IV criteria with severity of the major depressive episode > 16 scores on 17-item Hamilton Rating Scale for Depression ( HDRS ) ( Group 1 , n = 16 ) , we included a heterogeneous group of patients with less severe major depressive episodes or with a variety of comorbid conditions ( Group 2 , n = 24 ) . We r and omly assigned the patients to an RUL ECT treatment dosed at 5 or 2.5 times seizure threshold with an intent-to-treat design . The outcomes measured blindly were HDRS , number of treatments , and Mini-Mental State Examination ( MMSE ) . The patients were considered to have responded to treatment if the improvement in HDRS score was at least 60 % and they had a total score of less than ten . Results The Group 2 patients responded poorer ( 8 % vs. 63 % ) , and had more often simultaneous worsening in their MMSE scores than Group 1 patients . The differences in the outcomes between the two different doses of RUL ECT treatment were not statistically significant . Conclusions ECT effectiveness seems to be lower in real-life heterogeneous patient groups than in homogeneous patient sample s used in experimental efficacy trials Background Agitated or violent patients constitute 10 % of all emergency psychiatric treatment . Management guidelines , the preferred treatment of clinicians and clinical practice all differ . Systematic review s show that all relevant studies are small and none are likely to have adequate power to show true differences between treatments . Worldwide , current treatment is not based on evidence from r and omised trials . In Brazil , the combination haloperidol-promethazine is frequently used , but no studies involving this mix exist . Methods TREC-Rio ( Tranquilização Rápida-Ensaio Clínico [ Translation : Rapid Tranquillisation- Clinical Trial ] ) will compare midazolam with haloperidol-promethazine mix for treatment of agitated patients in emergency psychiatric rooms of Rio de Janeiro , Brazil . TREC-Rio is a r and omised , controlled , pragmatic and open study . Primary measure of outcome is tranquillisation at 20 minutes but effects on other measures of morbidity will also be assessed . TREC-Rio will involve the collaboration of as many health care professionals based in four psychiatric emergency rooms of Rio as possible . Because the design of this trial does not substantially complicate clinical management , and in several aspects simplifies it , the study can be large , and treatments used in everyday practice can be evaluated OBJECTIVE To determine the incidence and causes of agitation states in patients presenting at the Rouen University Hospital emergency room and to analyze the management scheme . PATIENTS AND METHOD A prospect i ve study was conducted over a 9 month period in 100 consecutive patients presenting a state of agitation assessed using the Overt Aggression Scale . A pre-planned management protocol was applied . RESULTS The incidence of states of agitation was 0.56 % . There were 43 women and 57 men , mean age 33 years . Most of the agitated patients were admitted between 6 p.m. and 4 a.m. ( 69 % ) . Over the 9 month period , 2 patients were admitted twice for agitation and 2 absconded . Low glucose level was the cause of agitation in 4 cases . Alcohol and /or drug use concerned 73 % of the agitated patients and was the most frequently observed triggering factor ( 17 % ) . Only 6 % of the patients had a regular employment . Physical restraining measures and sedation were required in 86 % and 84 % of the cases respectively . Among 67 patients given loxapine for sedation , 2 developed acute dyskinesia and 9 low blood pressure . One out of 4 patients were referred to a psychiatric unit . CONCLUSION Patients in a state of agitation are young , often female , and in a difficult socio-economic situation . Hypoglycemia is the main differential diagnosis . A triggering factor can often be identified . A state of agitation is not a repetitive condition but occurs as a short-lived episode in the patientís history . Such patients need rapid care to avoid further aggravation and disruption of the emergency room activity , and to prevent the patient from fleeing . Loxapine provides effective sedation but requires regular monitoring of blood pressure and can provoke acute dyskinesia in young subjects The authors estimated components of variance and intraclass correlation coefficients ( ICCs ) to aid in the design of complex surveys and community intervention studies by analyzing data from the Health Survey for Engl and 1994 . This cross-sectional survey of English adults included data on a range of lifestyle risk factors and health outcomes . For the survey , households were sample d in 720 postal code sectors nested within 177 district health authorities and 14 regional health authorities . Study subjects were adults aged 16 years or more .  ICCs and components of variance were estimated from a nested r and om-effects analysis of variance . Results are presented at the district health authority , postal code sector , and household levels . Between-cluster variation was evident at each level of clustering . In these data , ICCs were inversely related to cluster size , but design effects could be substantial when the cluster size was large . Most ICCs were below 0.01 at the district health authority level , and they were mostly below 0.05 at the postal code sector level . At the household level , many ICCs were in the range of 0.0 - 0.3 . These data may provide useful information for the design of epidemiologic studies in which the units sample d or allocated range in size from households to large administrative areas Background The medical management of aggressive and violent behaviour is a critical situation for which there is little evidence . In order to prepare for a r and omised trial , due to start in the psychiatric emergency rooms of Rio de Janeiro in 2001 , a survey of current practice was necessary . Methods A seven day survey of pharmacological management of aggressive people with psychosis in the emergency rooms of all four public psychiatric hospitals in Rio de Janeiro , Brazil . Results In one hospital data were not available . Of the 764 people with psychosis attending these ERs , 74 were given IM medication for rapid tranquillisation ( 9.7 % , 2.1/week/100,000 ) . A haloperidol-promethazine mix ( with or without other drugs ) was used for the majority of patients ( 83 % ) . Conclusion The haloperidol-promethazine mix , given intramuscularly for rapid tranquilization , is prevalent in Rio , where it is considered both safe and efficient . However , scientific evaluation of all pharmacological approaches to rapid tranquilization of psychotic people is inadequate or incomplete and a r and omized trial of IM haloperidol-promethazine is overdue Controlled clinical trials of the treatment of acute myocardial infa rct ion offer a unique opportunity for the study of the potential influence on outcome of bias in treatment assignment . A group of 145 papers was divided into those in which the r and omization process was blinded ( 57 papers ) , those in which it may have been unblinded ( 45 papers ) , and those in which the controls were selected by a nonr and om process ( 43 papers ) . At least one prognostic variable was maldistributed ( P less than 0.05 ) in 14.0 per cent of the blinded-r and omization studies , in 26.7 per cent of the unblinded-r and omization studies , and in 58.1 per cent of the nonr and omized studies . Differences in case-fatality rates between treatment and control groups ( P less than 0.05 ) were found in 8.8 per cent of the blinded-r and omization studies , 24.4 per cent of the unblinded-r and omization studies , and 58.1 per cent of the nonr and omized studies . These data emphasize the importance of keeping those who recruit patients for clinical trials from suspecting which treatment will be assigned to the patient under consideration This double-blind clinical trial studied 16 acutely agitated psychotic patients with manic or manic-like symptoms who needed rapid tranquilization and were therefore on maintenance treatment . They were r and omized to receive intramuscular preparations of clonazepam ( 1 to 2 mg ) or haloperidol ( 5 to 10 mg ) at 0 , 0.5 , and 1.0 hours . Both medications produced significant reduction of manic symptoms within two hours of initial treatment ; however , haloperidol produced beneficial results more rapidly than clonazepam . All patients completed the study , with the exception of one haloperidol-treated patient who developed severe parkinsonism . It was concluded that I.M. clonazepam is an effective , safe , but slower-acting alternative to I.M. haloperidol in the treatment of agitated psychiatric patients in need of rapid tranquilization Abstract Objective To compare two widely used drug treatments for people with aggression or agitation due to mental illness . Design Pragmatic , r and omised clinical trial . Setting Three psychiatric emergency rooms in Rio de Janeiro , Brazil . Subjects 301 aggressive or agitated people . Interventions Open treatment with intramuscular midazolam or intramuscular haloperidol plus promethazine . Main outcome measures Patients tranquil or se date d at 20 minutes . Secondary outcomes : patients tranquil or asleep by 40 , 60 , and 120 minutes ; restrained or given extra drugs within 2 hours ; severe adverse events ; another episode of agitation or aggression ; needing extra visits from doctor during first 24 hours ; overall antipsychotic load in first 24 hours ; and not discharged by two weeks . Results 151 patients were r and omised to midazolam , and 150 to haloperidol-promethazine mix . Follow up for the primary outcome was available for 298 ( 99 % ) : 134/151 ( 89 % ) of patients given midazolam were tranquil or asleep after 20 minutes compared with 101/150 ( 67 % ) of those given haloperidol plus promethazine ( relative risk 1.32 ( 95 % confidence interval 1.16 to 1.49 ) ) . By 40 minutes , midazolam still had a statistically and clinical ly significant 13 % relative advantage ( 1.13 ( 1.01 to 1.26 ) ) . After 1 hour , about 90 % of both groups were tranquil or asleep . One important adverse event occurred in each group : a patient given midazolam had transient respiratory depression , and one given haloperidol-promethazine had a gr and e mal seizure . Conclusions Both treatments were effective . Midazolam was more rapidly sedating than haloperidol-promethazine , reducing the time people are exposed to aggression . Adverse effects and re sources to deal with them should be considered in the choice of the treatment OBJECTIVE The purpose of the study was to examine the quantitative risk of criminal behavior associated with specific mental disorders . METHOD An unselected 1966 birth cohort ( N = 12,058 ) in Northern Finl and was prospect ively studied until the end of 1992 . The investigation started during the mothers ' pregnancy , and the data on the subjects ' family characteristics , mental and physical development , living habits , psychiatric morbidity , and criminal records were gathered at various times . RESULTS The prevalence of offenses was the highest among males with alcohol-induced psychoses and male schizophrenic subjects with coexisting alcohol abuse , and more than half of the schizophrenic offenders also had problems with alcohol . Eleven ( 7 % ) of the 165 subjects who committed violent crimes were diagnosed as psychotic . Male schizophrenic subjects had a moderately high risk for violent offenses , but the risk for other types of crimes was not elevated significantly . Odds ratios for criminal behavior were adjusted according to the socioeconomic status of the childhood family and were the same as or slightly lower than the crude odds ratios for all disorders except schizophrenia and mood disorders with psychotic features . CONCLUSIONS The results indicate that the risk of criminal behavior was significantly higher among subjects with psychotic disorders , even though the socioeconomic status of the childhood family was controlled . The higher risk for violent behavior was associated especially with alcohol-induced psychoses and with schizophrenia with coexisting substances abuse . The results suggest that schizophrenia without substance abuse may also be associated with a higher risk of offenses , but this finding is tentative and requires further investigation A modification of an earlier rating scale for extrapyramidal system disturbance is described , and
