[Differential diagnosis of first episode psychosis: importance of optimal approach in psychiatric emergencies]. / Diagnóstico diferencial de primeiro episódio psicótico: importância da abordagem otimizada nas emergências psiquiátricas.

OBJECTIVE: To review the literature regarding the diagnosis of first episode psychosis in the context of emergency psychiatry. METHOD: Review of empirical and review articles selected by electronic search in the database PubMed. RESULTS: Specific features of emergency care--single, brief and cross section assessment, and with little information--may jeopardize the diagnostic process. These limitations can be circumvented by application of operational diagnostic criteria, the use of scales and structured interviews and a short period of observation, between 24-72 hours. Diagnoses of bipolar disorder, schizophrenia, psychotic depression and delusional disorder developed in the context of emergency have good stability, but not the diagnoses of brief psychotic disorder, schizophreniform disorder and schizoaffective disorder. First episode psychosis can occur in the course of the use of psychoactive substances, with relatively frequent maintenance of psychotic symptoms even after cessation of the use of the substance. The rational use of subsidiary tests may help the differential diagnosis of psychotic episodes due to general medical conditions. CONCLUSION: Diagnoses of first psychotic episode can be adequately performed during psychiatric emergencies, if routines are implemented based on scientific evidence.

Stability of the diagnosis of first-episode psychosis made in an emergency setting.

OBJECTIVE: This study aimed at evaluating the stability of the first psychotic episode diagnosis in the emergency context. METHODS: Fifty-nine patients were selected during a 15-month period and were followed for an average of 19.35 +/- 6.12 months. The admission and discharge emergency diagnosis were compared with the longitudinal diagnosis, obtained by the application of Structured Clinical Interview for DSM-IV Axis I Disorders--clinical version at the end of the follow-up. Severity rating scales (Brief Psychiatric Rating Scale, Young Mania Rating Scale and Hamilton Rating Scale for Depression) were applied in the emergency assessment. RESULTS: Agreement between admission emergency diagnosis and longitudinal diagnosis was unsatisfactory (k=0.25), whereas that between emergency discharge and longitudinal diagnosis was satisfactory (k=0.57). Brief psychotic disorder diagnosis presented higher sensitivity rates but low specificity, comprising several false positives. Bipolar disorder had the highest rates of specificity. CONCLUSION: Brief psychotic disorder may not be a useful concept in the emergency assessment. A short period of observation can improve emergency psychiatric diagnosis.

[A comparison of consultative psychiatric services in two Brazilian university hospitals using a standardized protocol for recording liaison consultations]. / Comparação entre solicitações psiquiátricas de dois hospitais gerais universitários brasileiros: uso do protocolo de registro de interconsulta em saúde mental.

The objective of the present report was to compare consultative psychiatric services in two Brazilian university hospitals and to evaluate the applicability of a standardized protocol (PRISMe) for recording psychiatric liaison consultations. Analyses of psychiatric consultations and the attached protocol were performed. 541 consecutive liaison consultations were included in the final sample (438 consecutive consultations from the Federal university hospital in São Paulo and 103 from the Federal university hospital in Santa Catarina). In both hospitals, the majority of patients were female, married, white, and 31 to 60 years of age. Depression and adjustment and personality disorders were the most common psychiatric diagnoses, which could explain the higher referral of female patients. The results are consistent with the Brazilian and international literature, and the differences between the two hospitals could be related to both logistical differences between the consultative psychiatric services and the socioeconomic contexts. The findings confirm the applicability of the PRISMe and suggest that systematization of clinical and demographic information is important for future comparative studies.

Psychiatric disorders and traumatic brain injury.

Psychiatric disorders after traumatic brain injury (TBI) are frequent. Researches in this area are important for the patients' care and they may provide hints for the comprehension of primary psychiatric disorders. Here we approach epidemiology, diagnosis, associated factors and treatment of the main psychiatric disorders after TBI. Finally, the present situation of the knowledge in this field is discussed.

Diagnóstico diferencial de primeiro episódio psicótico: importância da abordagem otimizada nas emergências psiquiátricas / Differential diagnosis of first episode psychosis: importance of optimal approach in psychiatric emergencies

OBJETIVO: Revisar dados da literatura relativos ao diagnóstico de primeiro episódio psicótico no contexto das emergências psiquiátricas. MÉTODO: Revisão de artigos empíricos e de revisão selecionados por meio de busca eletrônica no indexador PubMed. RESULTADOS: Características específicas de atendimento de emergência - avaliação única e breve, em corte transversal e com poucas informações disponíveis - podem dificultar o processo diagnóstico. Essas limitações podem ser contornadas por meio da aplicação adequada de critérios diagnósticos operacionais, do uso de escalas e entrevistas diagnósticas padronizadas e de um tempo mínimo de observação de 24 a 72 horas. Diagnósticosdetranstornobipolar,esquizofrenia,depressãopsicóticaetranstorno delirante elaborados em contexto de emergência apresentam boa estabilidade temporal, não ocorrendo o mesmo com diagnósticos de transtorno psicótico breve, transtorno esquizofreniforme e transtorno esquizoafetivo. Primeiro episódio psicótico pode ocorrer na vigência do uso de substâncias psicoativas, sendo relativamente frequente a manutenção do quadro psicótico mesmo após cessação do uso. A utilização racional de exames complementares pode ajudar no diagnóstico diferencial com episódios psicóticos devido a condições médicas gerais. CONCLUSÃO: Diagnósticos de primeiro episódio psicótico podem ser adequadamente realizados durante emergências psiquiátricas, desde que sejam implementadas rotinas baseadas em evidências científicas.

Comparação entre solicitações psiquiátricas de dois hospitais gerais universitários brasileiros: uso do protocolo de registro de interconsulta em saúde mental / A comparison of consultative psychiatric services in two Brazilian university hospitals using a standardized protocol for recording liaison consultations

O objetivo do presente estudo foi comparar pedidos de interconsulta psiquiátrica realizados para dois hospitais gerais universitários brasileiros e avaliar a aplicabilidade de um protocolo de registro de interconsulta psiquiátrica (PRISMe). Foi realizada análise dos pedidos de interconsulta, do PRISMe anexado a eles e o número total de pedidos de interconsulta incluídos na amostra foi 541 (438 pedidos de interconsulta do HCFMRP-USP e 103 pedidos de interconsulta do HU-UFSC). Observou-se maior freqüência de solicitação para pacientes do sexo feminino, caucasianos, entre 31 a 60 anos e casados. Os diagnósticos psiquiátricos mais freqüentes foram depressão, transtornos de adaptação e de personalidade. Os resultados estão de acordo com a literatura nacional e internacional e as diferenças encontradas podem ser atribuídas às diferenças na infra-estrutura das instituições e nos contextos sócio-econômicos nos quais estão inseridas. Achados do presente estudo demonstram a aplicabilidade do PRISMe e sugerem que podem facilitar a sistematização da obtenção de achados clínico-demográficos e a comparabilidade entre as diferenças.(AU)
