    Aims: This study aimed to make a comparison of the mental health status between Japanese-Brazilian children in Japan and in Brazil. Methods: A total of 331 Japanese-Brazilian children at five Brazilian schools in Japan (Japanese Group), and 172 Japanese-Brazilian children at one private school in Sao Paulo (Brazilian Group) were enrolled in statistical analyses. The Strength and Difficulties Questionnaire was applied for parents, teachers, and students who were aged over 11 years old. Results: The total comparison of the Strength and Difficulties Questionnaire scores between the two groups demonstrated that all the average symptom scores except prosocial behavior were significantly higher in the Japanese Group by parent report. By teacher report, the average symptom scores of conduct problems, hyperactivity, peer problems and total difficulties were significantly higher in the Japanese Group, while that of the prosocial behavior was significantly higher in the Brazilian Group. Dividing parent and teacher reports into two age ranges, similar results to the total comparison were seen in the parent report in the age range of 4-10-year-olds and both parent and teacher reports in that of 11-16-year-olds, while in the teacher report for 4-10-year-olds, only conduct problems and total difficulties score showed significantly higher average scores in the Japanese Group. By self-report, the average symptom scores of emotional symptoms, peer problems and total difficulties score were significantly higher in the Japanese Group. Conclusion: The results indicate poorer mental health status in the Japanese Group than the Brazilian Group, and suggest the adverse circumstances of the former group both at their homes and schools.

    Few studies have investigated the long-term course of patients with acute polymorphic psychotic disorder, despite the clinical relevance. The present study focused on the frequency of acute polymorphic psychotic disorder without symptoms of schizophrenia (F23.0) and the prognosis of patients with the disorder over a long period. A total of 388 inpatients with nonaffective psychosis were examined and cases with F23.0 were retrospectively investigated regarding clinical course over 12 years with reference to clinical charts. A total of 16 cases were diagnosed with F23.0 according to first episode. After 12 years, five cases were rediagnosed with schizophrenia, and one case with borderline-type emotionally unstable personality disorder, although the diagnosis of F23.0 was not changed in 10 older patients. Of the four cases with > 2 repeated episodes of F23.0, the same clinical picture as in the first episode was observed in three, while one case showed continuous residual symptoms. F23.0 does not represent a homogeneous clinical entity. In some cases, diagnosis changes to schizophrenia, but others display repeated episodes of F23.0.

    The aim of the present study was to assess the mental health status of Japanese-Brazilians living in Kiyoharadai, Japan and compare the findings with the Japanese-Brazilians living in Bauru, Brazil. A comparative community-based mental health survey was conducted from November 1997 to April 1999 on a randomly selected sample of Brazilians of Japanese descent living in Bauru, Brazil (n=213) and on the entire Brazilian community of Kiyoharadai, Utsunomiya, Japan (n=158), using the self-reporting questionnaire (SRQ-20). Analysis was done by chi(2) Fisher and multiple logistic regression. Scores indicating probable cases of minor psychiatric disorders, were found in 3.2% of the community in Bauru city and 17.8% (OR=7.01) of the community in Kiyoharadai. The sociodemographic data indicated that those with high SRQ-20 scores were most likely to be female (OR=2.98), smokers (OR=2.76). and those whose former occupation was student when living in Brazil (OR=9.57). The mental health status of the Japanese-Brazilians living in Kiyoharadai, Japan is significantly worse than that of the community living in Bauru, Brazil, particularly among women, smokers and those who were students when living in Brazil. Further research concerning the mental health of this community is necessary and assistance provided.
