Intervenção precoce em psicose: um mapa das iniciativas clínicas e de pesquisa na América Latina

OBJECTIVE: This article aims to review Latin America's early intervention services in psychosis and to shed light into their challenges and particularities. METHOD: An internet-based search comprising medical societies' websites, published articles, and major universities' websites was conducted and the results were critically discussed. RESULTS: Latin American countries are profoundly deficient in specialized early intervention services. Our search found seven target services, four of which are based in urban areas of Brazil, inside tertiary hospitals or universities. Among the initiatives advanced by these centers, there are partnerships with the public educational system and other community-based efforts toward knowledge transfer. On the other hand, several challenges remain to be overcome, especially in relation to their expansion, which is necessary to match the existing demand.OBJETIVO: Este artigo tem o objetivo de revisar os serviços de intervenção precoce em psicose na América Latina e lançar luz sobre seus desafios e particularidades.

New Insights in the Management of Antipsychotics in the Treatment of Schizophrenia in a Patient with Prolactinoma: A Case Report and Review of the Literature

Prolactinomas are the commonest pituitary adenomas and the major pathological cause of hyperprolactinaemia. Symptomatic prolactinomas are treated mainly by dopamine agonists; surgery and radiotherapy are options for nonresponders. Schizophrenia treatment is based on antipsychotics, which acts mainly at serotonergic and dopaminergic systems. We report a case of a 39-year-old schizophrenic male patient that was diagnosed with a macroprolactinoma 8 years after his first psychotic episode. The association of Schizophrenia and prolactinoma represents a clinical challenge once the treatment of one disease can exacerbate the symptoms of the other

Evaluating the effectiveness of a training program that builds teachers' capability to identify and appropriately refer middle and high school students with mental health problems in Brazil: an exploratory study

Background: in Brazil, like many countries, there has been a failure to identify mental health problems (MHP) in young people and refer them to appropriate care and support. the school environment provides an ideal setting to do this. Therefore, effective programs need to be developed to train teachers to identify and appropriately refer children with possible MHP. We aimed to evaluate teachers' ability to identify and appropriately refer students with possible MHP, and the effectiveness of a psychoeducational strategy to build teachers' capability in this area.Methods: To meet the first objective, we conducted a case-control study using a student sample. To meet the second, we employed longitudinal design with repeated measures before and after introducing the psychoeducational strategy using a teacher sample. in the case control study, the Youth Self-Report was used to investigate internalizing and externalizing problems. Before training, teachers selected 26 students who they thought were likely to have MHP. Twenty-six non-selected students acted as controls and were matched by gender, age and grade. the underlying principle was that if teachers could identify abnormal behaviors among their actual students, those with some MHP would likely be among the case group and those without among the control group. in the longitudinal study, 32 teachers were asked to evaluate six vignettes that highlighted behaviors indicating a high risk for psychosis, depression, conduct disorder, hyperactivity, mania, and normal adolescent behavior. We calculated the rates of correct answers for identifying the existence of some MHP and the need for referral before and after training; teachers were not asked to identify the individual conditions.Results: Teachers were already able to identify the most symptomatic students, who had both internalizing and externalizing problems, as possibly having MHP, but teachers had difficulty in identifying students with internalizing problems alone. At least 50.0% of teachers learned to identify hypothetical cases as problematic and to make the appropriate referral, and 60.0% of teachers who before training could not identify normal adolescence learned to do so.Conclusions: the strategy was partially effective but could be improved mainly by extending its duration, and including discussion of actual cases.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Federal de São Paulo UNIFESP, Dept Psychiat, BR-04038030 São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Psychiat, LINC, BR-04038030 São Paulo, BrazilNatl Inst Dev Psychiat Children & Adolescents INP, São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Psychiat, BR-04038030 São Paulo, BrazilUniversidade Federal de São Paulo UNIFESP, Dept Psychiat, LINC, BR-04038030 São Paulo, BrazilWeb of Scienc

Is disorganized schizophrenia a predictor of treatment resistance? Evidence from an observational study

Objective: To investigate whether inpatients with disorganized schizophrenia are more resistant to treatment. Method: Eighty-five inpatients were assessed at admission and at discharge for schizophrenia subtype, symptom severity, and treatment resistance criteria. Results: Disorganized patients were significantly more treatment-resistant than paranoid patients (60%, p = 0.001), and presented worse scores on the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression Scale (CGI-S), and the Global Assessment of Functioning Scale (GAF) (p < 0.001). Although the difference was not significant, 80% of treatment-resistant patients with disorganized schizophrenia responded to clozapine. Conclusion: Patients with the disorganized subtype of schizophrenia should benefit from clozapine as a second-line agent.Universidade Federal de São Paulo (UNIFESP) Schizophrenia ProgramAssociação Paulista para o Desenvolvimento da Medicina (SPDM) Hospital das Clínicas Luzia de Pinho Melo Department of PsychiatryUNIFESP Interdisciplinary Laboratory of Clinical NeurosciencesSão José do Rio Preto Medical School Department of Psychiatry and Medical PsychologyUNIFESP, Schizophrenia ProgramUNIFESP, Interdisciplinary Laboratory of Clinical NeurosciencesSciEL

Diagnostic operationalization and phenomenological heterogeneity in psychiatry : the case of attention deficit hyperactivity disorder

Introduction. We assessed the impact of polythetic conceptualizations of mental disorders on the validity and reliability of psychiatric diagnosis, with a specific focus on two levels of heterogeneity: phenomenological and pathophysiological. Objective. We investigated this issue using attention deficit hyperactivity disorder (ADHD) as an example. Method. We examined individuals from two samples enriched for psychopathology (n = 1 255 children in Porto Alegre and 1 257 children in São Paulo, Brazil). We conducted a series of data analyses to investigate phenomenological heterogeneity, including confirmatory factor analysis. We also investigated pathophysiological heterogeneity using symptom-level regressions between ADHD symptoms and four neurocognitive processes consistently linked to ADHD (working memory, inhibitory control, intra-subject variability in reaction times, and temporal processing). Lastly, we assessed the performance of polythetic systems for reliability testing inter-rater and test-rest reliability of two well-known symptomatic scales. Results. Among the 116 200 possible combinations of symptoms to achieve DSM symptomatic threshold for categorical ADHD diagnosis, we found 173 combinations in the two independent samples, and only four were replicated in both samples (2.3%). We also found that the number of ADHD symptoms is a poor indicator of variation in the general ADHD latent trait. Overall, symptoms did not have specific profiles of associations with any of the neurocognitive processes. Reliability analyses revealed that increasing the number of items augments overall reliability of measurements. Discussion and conclusion. Our findings illustrate both potential benefits and problems inherent to the polythetic system for ADHD. Implications for the search of mechanisms underlying psychiatric disorders are discussed.Antecedentes. Evaluamos el impacto de las conceptualizaciones politécnicas de los trastornos mentales en la validez y la fiabilidad del diagnóstico psiquiátrico, con un enfoque específico en dos niveles de heterogeneidad: fenomenológico y fisiopatológico. Objetivos. Investigamos este problema utilizando el trastorno por déficit de atención e hiperactividad (TDAH) como ejemplo. Método. Examinamos individuos de dos muestras enriquecidas por psicopatología (n = 1 255 niños en Porto Alegre y 1 257 niños en São Paulo, Brasil). Llevamos a cabo una serie de análisis de datos para investigar la heterogeneidad fenomenológica, incluido el análisis factorial confirmatorio. También investigamos la heterogeneidad fisiopatológica utilizando regresiones al nivel de síntomas entre los síntomas del TDAH y cuatro procesos neurocognitivos consistentemente vinculados al TDAH (memoria de trabajo, control inhibitorio, variabilidad intrasujeto en tiempos de reacción y procesamiento temporal). Por último, evaluamos el rendimiento de los sistemas politéticos para la prueba de confiabilidad interevaluador y la confiabilidad test-rest de dos escalas sintomáticas bien conocidas. Resultados. Entre las 116 200 posibles combinaciones de síntomas para alcanzar el umbral sintomático del DSM para el diagnóstico categórico de TDAH, encontramos 173 combinaciones en las dos muestras independientes y sólo cuatro se replicaron en ambas muestras (2.3%). También encontramos que la cantidad de síntomas de TDAH no es un buen indicador de la variación en el rasgo latente general del TDAH. En general, los síntomas no tenían perfiles específicos de asociaciones con ninguno de los procesos neurocognitivos. Los análisis de confiabilidad revelaron que aumentar el número de artículos aumenta la confiabilidad general de las mediciones. Discusión y conclusión. Nuestros hallazgos ilustran tanto los beneficios potenciales como los problemas inherentes al sistema politécnico para el TDAH. Se discuten las implicaciones para la búsqueda de mecanismos subyacentes a los trastornos psiquiátricos

Impact of training in autism for primary care providers: a pilot study

Objective: To evaluate the impact of a training program on autism spectrum disorder (ASD) identification offered to Brazilian health professionals. Methods: Twenty-two primary care providers participated in five 3-hour weekly training sessions. Results: The trained providers significantly improved their ASD knowledge after training in comparison with pre-training (mean score, 6.73 vs. 9.18, p < 0.01). Clinical practice also changed: 4 months after the training program, the providers had referred six times as many suspected cases of ASD to a specialized mental health service in comparison with the previous 4 months. Conclusion: This pilot training model seems a promising, feasible, and inexpensive way to improve early identification of ASD in the primary care system.Universidade Federal de São Paulo (UNIFESP) Department of Psychiatry Child and Adolescent Psychiatry Unit (UPIA)Santa Casa de Misericórdia de São Paulo School of Medical Sciences Unit of Excellence in Autism Spectrum DisorderUniversidade Federal de São Paulo (UNIFESP) Department of PsychiatryFaculdade de Medicina de São José do Rio Preto Department of Psychiatry and Medical PsychologyUniversity of London King's College Institute of PsychiatryUniversidade Presbiteriana Mackenzie Graduate Program in Developmental DisordersUNIFESP, Department of Psychiatry Child and Adolescent Psychiatry Unit (UPIA)UNIFESP, Department of PsychiatrySciEL

Fisiopatologia da esquizofrenia: aspectos atuais

BACKGROUND: Schizophrenia is one of the most intriguing and studied psychiatric diseases and its physiopathology has advanced a lot in the last century. OBJECTIVE: To review the most important advances in the physiopathology of schizophrenia. METHOD: Review of the literature of each proposed topic by articles searched in Medline and/or chosen accordingly the authors experience. RESULTS: The dopaminergic hypothesis was one of the first ethiological theories and until today is among the ones that presents the most consistent evidences. However, it fails to explain important features found in schizophrenia, such as the natural history, the cognitive impairments and the structural abnormalities. Evidences provided by epidemiological studies of genetic and environmental risk factors, associated with the findings of neuropathological and neuroimaging studies, suggest an interactive model with several factors acting together to create a global alteration of the brain development. CONCLUSION: The physiophatology of schizophrenia has advanced a lot in the last century, evolving from unicausal theories towards more complex models that consider the interaction among several genetic and environmental factors.CONTEXTO: A esquizofrenia é uma das mais intrigantes doenças psiquiátricas e, talvez por isso, a mais pesquisada, com grandes avanços sobre sua fisiopatologia no último século. OBJETIVO: Revisar os principais avanços na compreensão fisiopatológica da esquizofrenia. MÉTODO: Revisão da literatura para cada tópico proposto a partir de artigos levantados no Medline e/ou considerados importantes a partir da experiência dos autores. RESULTADOS: A hipótese dopaminérgica representa uma das primeiras teorias etiológicas e permanece até os dias atuais como uma das que apresenta evidências mais consistentes. No entanto, essa teoria falha em explicar a história natural, os prejuízos cognitivos e as alterações estruturais encontradas na esquizofrenia. A demonstração de estudos epidemiológicos de fatores de risco genéticos e ambientais, somados aos estudos neuropatológicos e de neuroimagem, sugerem um modelo interativo em que inúmeros fatores atuam conjuntamente para alterações mais globais do desenvolvimento cerebral. CONCLUSÃO: A compreensão fisiopatológica da esquizofrenia avançou bastante no último século, evoluindo de teorias etiológicas unicausais para modelos mais complexos que consideram a interação de inúmeros fatores genéticos e ambientais

The role of the CNR1 gene in schizophrenia: a systematic review including unpublished data

Objective: Schizophrenia is a multifactorial disorder. It is known that a combination of extensive multiple common alleles may be involved in its etiology, each contributing with a small to moderate effect, and, possibly, some rare alleles with a much larger effect size. We aimed to perform a systematic review of association studies between schizophrenia (and its subphenotypes) and polymorphisms in the CNR1 gene, which encodes cannabinoid receptors classically implicated in schizophrenia pathophysiology, as well as to present unpublished results of an association study in a Brazilian population. Methods: Two reviewers independently searched for eligible studies and extracted outcome data using a structured form. Papers were retrieved from PubMed and ISI Web of Knowledge using the search term schizophrenia in combination with CNR1 or CB1 or cannabinoid receptor. Twenty-four articles met our inclusion criteria. We additionally present data from a study of our own comparing 182 patients with schizophrenia and 244 healthy controls. Results: No consistent evidence is demonstrated. Conclusion: Some seemingly positive association studies stress the need for further investigations of the possible role of endocannabinoid genetics in schizophrenia.Fundacao de Amparo e Pesquisa do Estado de Sao Paulo (FAPESP) [2010/08968-6, 2011/50740-5, 2011/00030-1]Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)FAPESPCNPqCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Fundacao SafraFundacao ABADSUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Lab Interdisciplinar Neurociencias Clin LiNC, Sao Paulo, SP, BrazilIrmandade Santa Casa Misericordia Sao Paulo, Dept Psiquiatria, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Dept Morfol & Genet, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Lab Interdisciplinar Neurociencias Clin LiNC, Sao Paulo, SP, BraziWeb of Scienc
