Association between personality disorder and violent behavior pattern

Personality disorders are associated with criminality and antisocial and borderline personalities as strong predictors of violence. Nevertheless antisocial patients show more instrumental violence, while borderline patients more emotional violence. We surveilled medical records of a personality disorder facility, searching data of aggression and crimes against property among 11 patients with antisocial personality disorder and 19 borderline personality disorder. We found that there are differences regarding engagement in violence and lawbreaking according to the personality disorder: antisocial patients statistically engage more in crimes against property than the borderline patients, and more in this kind of crime than in aggression, whilst borderline patients show a tendency to engage more in episodes of aggression and physical violence than antisocial patients, and less in crimes against property. We conclude that the distinct personality leads to a distinct pattern of crimes and violence: antisocial patients are c old and get more involved in crimes requiring more detailed planning, whilst borderline patients are impulsive and engage in explosive episodes of physical violence. Further studies on the association among personality disorder, behavior pattern and violence type may be useful for both treatment and criminal profiling. (C) 2008 Elsevier Ireland Ltd.

Incidence of violent behavior among patients in Psychiatric Intensive Care Units

Background and Objectives: Both psychiatric acute units and psychiatric intensive care units (PICUs) focus on acute treatment of behavioral disturbances such as violence and aggressive threats and acts. The aim of the present study is to describe the frequency of violent behavior; such as verbal or physical threats and physical attacks, among patients admitted to psychiatric intensive care unit (PICU). In addition the relationship between the episodes of threats and/or attacks in relation to time of the day, days of the week, and their seasonal variations was explored. Methods: All violent behavior was continuously assessed at the psychiatric emergency department. Data were collected during the period from May 2010 to May 2012. Results: Patients with only one hospitalization were less violent than those who have had two hospitalizations. There was a statistically significant difference in violence among patients without formal secondary education and those who have not formal education. Violent behavior showed two peaks during the day; the first occurring at 1 pm and the second at 8 pm. In regard to seasonality, summer had a higher incidence of violence. The most peaceful seasons of the year were spring and autumn. Conclusions: Violent behavior shows variation in daytime, days of the week and season in acute psychiatric intensive care. Daytime variation shows two peaks of violence at 1 pm and 8 pm, Sundays and Wednesdays being the quietest days regarding violence both in winter and summer. Patient's level of education and hospitalization status partially explain the variation.

Atypical antipsychotics in the treatment of pathological aggression in children and adolescents: literature review and clinical recommendations

Objective: To review the literature about the use of atypical antipsychotics in the treatment of pathological aggression in children and adolescents. Method: The databases MEDLINE, SciELO, and LILACS were searched for publications in Portuguese or English from 1992 to August 2011 using the following keywords: mental disease, child, adolescent, treatment, atypical antipsychotic, aggressive behavior, aggression, and violent behavior. Results: Sixty-seven studies of good methodological quality and clinical interest and relevance were identified. Studies including children and adolescents were relatively limited, because few atypical antipsychotics have been approved by the Food and Drug Administration (FDA). All the medications included in this review (risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole and clozapine) have some effectiveness in treating aggression in children and adolescents, and choices should be based on clinical indications and side effects. Conclusions: There are few studies about the effectiveness and safety of atypical antipsychotics for the pediatric population, and further randomized controlled studies with larger groups of patients and more diagnostic categories, such as severe conduct disorder and oppositional defiant disorder, should be conducted to confirm the results reported up to date and to evaluate the impact of long-term use.

Anorectal transplantation

Anorectal transplantation is a valid procedure for the treatment of anorectal dysfunction; however, the lack of a suitable animal model has hampered the development of this method. We describe a simple technique for anorectal transplantation in the rat and compare this procedure with colostomy. The anorectal segment including the skin surrounding the anus were freed by abdominal and perineal dissection. In a heterotopically transplanted group the segment was exteriorized by the formation of an anus through an abdominal incision. In an orthotopically transplanted group the segment was replaced in its original position and reimplanted by suturing. In another group a distal colostomy was performed. A sham-treated control group (simulated surgical procedure) was also included. Changes in behavior, characteristics of the stool, body weight and survival rate were assessed by daily clinical examination. Moribund animals, those with a weight loss of more than 30%, and those surviving at 1 month were killed by an overdose of anesthetic. The results were analyzed using the Mann Whitney, Student`s t and chi-squared tests, and p < 0.05 was considered significant. Within 4 days after the operation, animals submitted to orthotopic or heterotopic transplantation had achieved normal defecation, body weight gain and clinical evolution similar to the sham-treated group. The overall mortality in these groups was 4.16%. In contrast, colostomized animals showed a high incidence of diarrhea, intestinal obstruction, stress posture and violent behavior (pa parts per thousand currency sign0.05), and a mortality rate of 58.33%. Autotransplantation in the rat is a simple technique, achieves a high rate of success and better clinical evolution than colostomy. This model may ultimately lead to research into anorectal transplantation.

" (...) mais gosto de ti??? Diferenças entre homens e mulheres nas crenças e comportamentos sobre violência conjugal

O presente trabalho tem como objectivo analisar as diferenças de género nas crenças e comportamentos relacionados com a violência conjugal, fazendo uma avaliação de condutas e atitudes face ao fenómeno. Participaram no estudo 50 casais, que preencheram o Inventário de Violência Conjugal e a Escala de Crenças sobre Violência Conjugal. Os resultados apontam para a não existência de diferenças entre homens e mulheres na perpetração e vitimação de violência em relações íntimas. São os homens os que mais facilmente legitimam os comportamentos violentos, embora a tendência atitudinal flua no sentido de não a aprovar. ABSTRACT:This study aims to examine gender differences in beliefs and behaviors related to domestic violence, by making an assessment of behaviors and attitudes addressing the phenomenon. 50 couples supported the study by filling Inventário de Violência Conjugal and Escala de Crenças sobre Violência Conjugal. The results indicate that there are no substancial differences between men and women in the perpetration and victimization of violence in intimate relationships. Men are more easily prone to accredit violent behavior, although the sight tendency is not to approve.

Evolução do DSM quanto ao critério categorial de diagnóstico para o distúrbio da personalidade antissocial

OBJETIVO: Realizar um breve percurso sobre o desenvolvimento conceitual de um dos construtos psicológicos de maior evidência nos dias atuais, a saber: o transtorno de personalidade antissocial (TPAS). Especificamente, esse percurso se realiza no sistema categórico proposto pela Associação Americana de Psiquiatria (APA), o Manual Diagnóstico e Estatístico de Distúrbios Mentais (DSM). MÉTODO: Utilizou-se a revisão literária sobre a evolução e a avaliação do construto associada a pesquisas empíricas consultadas nos principais livros e periódicos de reconhecimento internacional na área, tais como: Personality and Individual Differences, Psychological Medicine, Annual Review of Clinical Psychology, Psychological Bulletin, Journal of Abnormal Psychology, Journal of Personality Assessment, International Journal of Offender Therapy and Comparative Criminology, Aggression and Violent Behavior, Handbook of Psychopathy, entre outros. RESULTADO: Observa-se que o diagnóstico do TPAS é baseado nos critérios categóricos e não dimensionais. Isso significa que o sistema não consegue predizer a priori a variabilidade (intensidade) dos traços desse transtorno por ser o DSM desenvolvido no reconhecimento de sintomas e síndromes. CONCLUSÃO: Apesar de o TPAS ter passado por diversas revisões e de apresentar insuficiência taxonômica, ele ainda é amplamente utilizado no diagnóstico e no prognóstico clínico de condições relacionadas ao comportamento social desviante.

Étude exploratoire des profils motivationnels de jeunes adultes violents au sein de leur couple

Les jeunes adultes commettent plus souvent des conduites violentes au sein de leur couple que les adultes plus âgés. Le but de cette étude est de proposer une classification de jeunes adultes violents au sein de leur couple à l’aide de variables motivationnelles et d’évaluer la validité discriminante des profils au niveau de variables liées à la violence psychologique et physique et de comparer les profils motivationnels à un groupe de jeunes adultes non violent. Les 457 participants de cette étude sont des jeunes adultes de la population générale provenant de la région de Québec et de Montréal. L’analyse de classification two-step cluster à permis de trouver trois profils distincts : (1) le réactif (2) le commun et (3) l’hostile. Les analyses comparatives démontrent que les réactifs sont ceux qui commettent le plus d’actes de violence physique différents, que les communs sont les moins violents, les moins en détresse et perçoivent l’impact de leur violence moins négativement et que les hostiles sont ceux qui sont les plus violents, les plus en détresse et perçoivent l’impact de leur violence plus négativement. Les individus non violents sont significativement moins en détresse et consomment moins d’alcool que tous les profils violents. Les résultats serviront à obtenir une meilleure compréhension des individus violents, à améliorer le dépistage des individus les plus à risque de recourir à la violence au sein de leur couple et d’effectuer de la prévention en les sensibilisant aux caractéristiques des individus violents.
