Stigma and higher rates of psychiatric re-hospitalization: Sao Paulo public mental health system

Objective: The aim of this study was to assess re-hospitalization rates of individuals with psychosis and bipolar disorder and to study determinants of readmission. Methods: Prospective observational study, conducted in Sao Paulo, Brazil. One hundred-sixty-nine individuals with bipolar and psychotic disorder in need of hospitalization in the public mental health system were followed for 12 months after discharge. Their families were contacted by telephone and interviews were conducted at 1, 2, 6 and 12 months post-discharge to evaluate readmission rates and factors related. Results: One-year re-hospitalization rate was of 42.6%. Physical restraint during hospital stay was a risk factor (OR = 5.4-10.5) for readmission in most models. Not attending consultations after discharge was related to the 12-month point readmission (OR = 8.5, 95% CI 2.3-31.2) and to the survival model (OR = 3.2, 95% CI 1.5-7.2). Number of previous admissions was a risk factor for the survival model (OR = 6.6-11.9). Family's agreement with permanent hospitalization of individuals with mental illness was the predictor associated to readmission in all models (OR = 3.5-10.9) and resulted in shorter survival time to readmission; those readmitted were stereotyped as dangerous and unhealthy. Conclusions: Family's stigma towards mental illness might contribute to the increase in readmission rates of their relatives with psychiatric disorders. More studies should be conducted to depict mechanisms by which stigma increases re-hospitalization rates.

Shear strength of reinforced concrete circular cross-section beams

A proposed adequation of NBR 6118, Item 7.4, related to shear strength of reinforced concrete beams is presented with aims to application on circular cross-section. The actual expressions are most suitable to rectangular cross-section and some misleading occurs when applied to circular sections at determination of VRd2, Vc and Vsw, as consequence of bw (beam width) and d (effective depth) definitions as well as the real effectiveness of circular stirrups. The proposed adequation is based on extensive bibliographic review and practical experience with a great number of infrastructure elements, such as anchored retaining pile walls, where the use of circular reinforced concrete members is frequent.

Irrupção dentária estimulada pelo enxerto ósseo alveolar na região da fissura

Introdução: Esse trabalho tem como objetivo relatar um caso clínico de irrupção dentária estimulada após a realização de enxerto ósseo alveolar num paciente com fissura transforame unilateral. Relato clínico: Paciente DMS de 8 anos de idade compareceu ao setor de Ortodontia para dar início ao tratamento. Verificou-se a presença de fissura transforame unilateral direita, padrão esquelético Classe I, mordida cruzada posterior unilateral direita e presença de dentes supranumerários na região da fissura. Após o planejamento, foi realizada a Expansão Rápida da Maxila com HAAS borboleta seguida da instalação de contenção fixa. O Enxerto Ósseo Alveolar foi realizado posteriormente, a fim de corrigir o defeito ósseo causado pela fissura e favorecer a irrupção dos dentes adjacentes a essa região, possibilitando uma adequada finalização ortodôntica. Resultados obtidos: Após a realização do Enxerto Ósseo Alveolar e reanatomização dos dentes satisfatoriamente irrompidos na região da fissura, verificou-se uma adequada harmonia funcional e estética, também favorecida pela ortodontia corretiva. Conclusões: A presença de dentes na região da fissura constitui um fator que ocorre comumente e deve ser ponderado a fim de possibilitar melhores resultados no tratamento destes pacientes.
