Os comportamentos autolesivos sem intenção suicida devem ser vistos como um modo de expressão de um conflito ou dificuldade vivencial do adolescente e, por isso, carecem de uma "descodificação" atenta. O presente estudo qualitativo teve como principal objetivo conhecer os significados e funções subjacentes a estes comportamentos numa amostra clínica de adolescentes. A amostra foi constituída por 25 participantes, recrutados na consulta externa do Serviço de Adolescência do Departamento de Psiquiatria da infância e da adolescência do Centro Hospitalar do Porto. A análise de conteúdo revelou a existência de funções intrapsíquicas e interpessoais, estando os comportamentos ao serviço de mais do que uma função, na maioria dos casos. Estas enquadraram-se em diferentes modelos explicativos teóricos, sendo possível identificar o predomínio de funções de alívio da tensão emocional e tentativa de fuga/retirada, ambas pertencentes ao modelo de Regulação emocional, e de funções interpessoais, enquadradas no modelo Ambiental. Embora exploratórios, estes resultados tendem a apoiar a investigação existente, apontando, contudo, para algumas especificidades. Evidenciam, ainda, a importância da avaliação atenta e compreensiva destes comportamentos de forma a aprimorar o seu tratamento.

IntroduçãoDiante das mudanças que se operam no seu corpo, o adolescente vive um período particularmente vulnerável, no qual existe uma potencialidade acentuada de mudança mas também de desequilíbrio. Carecendo de possibilidades de simbolização e de representatividade do caos interno, numa tendência à passagem ao ato como forma de dispensar a mentalização, a autolesão surge como uma alternativa em situação de conflito.Existem algumas divergências na comunidade científica relativas à definição dos comportamentos autolesivos. No presente trabalho, utilizamos a definição correspondente à definição anglo-saxónica de "non suicidal self-injury" para nos referirmos aos comportamentos autolesivos sem intenção suicida na adolescência como os atos de autodestruição direta do corpo sem intenção suicida associada que se refere apenas à destruição do tecido corporal do próprio na ausência de intencionalidade de morrer, incluindo apenas cortes (self-cutting) e comportamentos associados (p. ex., queimaduras, arranhões, etc.) (Nock, Joiner Jr., Gordon, Lloyd-Richardson, & Prinstein, 2006). 207A correspondência relativa a este artigo deverá ser enviada para:

IntroductionParental schizophrenia will potentially cause dysfunction in mother-child relationships, and it will also cause difficulty in adapting to motherhood.ObjectivesWe aim to study the implications of the relationship between mothers with schizophrenia and their children. The psychosocial environment and the impact of dysfunctional relationship in social skills development may cause behavioral disorders in children and further development of severe mental illness taking into account genetic factors and biopsychosocial factors.MethodsNon systematic literature review, through the Pubmed and Medline database, with time constraints.ResultsThe development of schizophrenia is related to genetic and environmental factors. Children of parents with schizophrenia are at increased risk of developing psychiatric disorder compared to the general population. It was found early behavioral disorders, starting between 5 and 8 years old and the difficulties in social interaction may arise at this age and remain until adulthood.ConclusionsIt is important to assess the level of acquisition of social skills in children and families when there is a direct relationship with schizophrenia. It may be important in the future, monitorize the development of these children, as well as be aware of the surrounding social and family environment, to identify and manage early in the presence of behavioral disorders and possible development of serious mental illness. An early intervention at the level of social deficits in children can be a preventive intervention of later schizophrenia development.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Several studies indicate that over 25% of child and adolescent inpatients were readmitted within one year of discharge. Several risk factors for psychiatric readmissions have been reported in the literature, but the history of repeated readmissions is the most consistent risk factor. Our aim is to calculate the readmission rates at 30 days and 12 months after discharge and to identify associated risk factors. Material and Methods:The authors consulted the clinical files of patients admitted to the Inpatient Unit between 2010 and 2013, in order to calculate the readmission rates at 30 days and at 12 months. The demographic and clinical characteristics of the readmitted patients were analyzed and compared with a second group of patients with no hospital readmissions, in order to investigate possible predictors of readmission. Results: A total of 445 patients were admitted to our inpatient unit between 2010 and 2013. Six adolescents were readmitted in a 30 days period (1.3%) and 52 were readmitted in a 12 month period after discharge (11.5%). Duration of the hospitalization and the previous number of mental health admissions were significant predictors of future hospital readmissions (p = 0.04 e p = 0.014). Discussion: The low readmission rates may reflect the positive clinical and sociofamilial support being provided after discharge. Conclusion: Rehospitalisation is considered a fundamental target for intervention concerning prevention and intervention in mental healthcare. Thus, knowledge regarding their minimisation is crucial.

Background: The present article aims to illustrate the overlap between anxiety disorders and a first cannabis use in adolescents. Although investigation in teenagers, comparatively to adults is sparse, the limited existent evidence showed a link between anxiety disorders and cannabis substance use. Methods: The authors present 3 case reports illustrating this association in adolescents, followed by a systematic review targeting panic episodes triggered by cannabis use. Results and Conclusions: Six studies examined the association between cannabis use and panic attacks. Current findings collectively suggest that cannabis use may be a risk factor for panic psychopathology in predisposed adolescents. The anxious symptoms in these cases lead to several attendances to the Emergency Department, commitment of the school attendance, and abandonment of physical activity, which is highly disabling for teens and their relatives.
