Realismo e pragmatismo em psiquiatria: um debate / Realism and pragmatism in Psychiatry: a debate / Réalisme et pragmatisme em Psychiatrie: un débat / Realismo y pragmatismo en Psiquiatría: un debate / Realismus und Pragmatismus in der Psychiatrie: eine Debatte

O artigo apresenta um debate sobre a natureza do objeto da psiquiatria. Apresentam-se duas perspectivas de abordagem da questão — o realismo e o pragmatismo. Segundo o realismo, as condições denominadas transtornos mentais existiriam de forma autônoma, a despeito da conceitualização humana. Já as perspectivas pragmáticas pressuporiam que transtornos mentais não são suficientemente explicados como tipos naturais, porque normas e interesses humanos sempre estariam presentes em classificações psiquiátricas. São descritas as características, diferenças e pontos de limitação dessas abordagens.

This paper presents a debate on the nature of the object of Psychiatry. Two approaches to the issue are discussed: realism and pragmatism. According to realism, would exist autonomously the conditions known as mental disorders regardless of human conceptualization. Pragmatist perspectives assume that mental disorders are not sufficiently explained as natural types, since human norms and interests are always at stake in the making of psychiatric classifications. The specific features, differences, and limitations of both approaches are described.

Les auteurs présentent une réflexion critique à propos de la nature de l’objet de la psychiatrie. D’emblée, ils postulent deux voies [approches] majeures permettant d’explorer cette question fondamentale: le réalisme et le pragmatisme. Selon le réalisme, les troubles mentaux existent comme des entites autonomes, de facon independant d’une structuration conceptuelle. D’autre part, l’approche pragmatique met en avant les enjeux sociaux ce qui permet d’en déduire et d’affirmer que les troubles mentaux ne sont pas réductible à de types naturels. Enfin, les auteurs examinent brièvement et mettent en évidence les caractéristiques et limites de ces différentes approches dans la clinique psychiatrique.

Para el realismo, los trastornos mentales existen autónomamente, a pesar de la conceptua-lización humana. Las perspectivas pragmáticas suponen que los trastornos mentales no pueden ser explicados suficientemente como tipos naturales, pues las clasificaciones psiquiátricas son siempre atravesadas por normas e intereses humanos. Son descritas las características, diferencias y límites de ambos enfoques.

In diesem Artikel präsentieren wir eine Debatte über die Natur des Objektes in der Psychiatrie. Wir bieten somit zwei perspektiven bezüglich dieser Problematik- den Realismus einerseits, und den Pragmatismus als gegen Stellung. Für den Realismus würden die sogenannten Bedingungen der Psychiatrischen Störungen auf autonomer Weise vorhanden sein, und dies trotz menschlicher Konstruktionen. Pragmatische Perspektiven setzten voraus das Psychische Störungen nicht genügend durch ‘natural kinds’ erklärt werden können, weil menschliche Normen und sonstige Interessen sonst immer in Psychiatrischen Klassifikationen zu finden sind. Die Charakteristiken, Unterschiede und Einschränkungen werden dieser Perspektiven werden hier beschrieben.

Cognitive and behavioral heterogeneity in genetic syndromes / Heterogeneidade cognitiva e comportamental em síndromes genéticas

OBJECTIVE: this study aimed to investigate the cognitive and behavioral profiles, as well as the psychiatric symptoms and disorders in children with three different genetic syndromes with similar sociocultural and socioeconomic backgrounds. METHODS: thirty-four children aged 6 to 16 years, with Williams-Beuren syndrome (n = 10), Prader-Willi syndrome (n = 11), and Fragile X syndrome (n = 13) from the outpatient clinics of Child Psychiatry and Medical Genetics Department were cognitively assessed through the Wechsler Intelligence Scale for Children (WISC-III). Afterwards, a full-scale intelligence quotient (IQ), verbal IQ, performance IQ, standard subtest scores, as well as frequency of psychiatric symptoms and disorders were compared among the three syndromes. RESULTS: significant differences were found among the syndromes concerning verbal IQ and verbal and performance subtests. Post-hoc analysis demonstrated that vocabulary and comprehension subtest scores were significantly higher in Williams-Beuren syndrome in comparison with Prader-Willi and Fragile X syndromes, and block design and object assembly scores were significantly higher in Prader-Willi syndrome compared with Williams-Beuren and Fragile X syndromes. Additionally, there were significant differences between the syndromes concerning behavioral features and psychiatric symptoms. The Prader-Willi syndrome group presented a higher frequency of hyperphagia and self-injurious behaviors. The Fragile X syndrome group showed a higher frequency of social interaction deficits; such difference nearly reached statistical significance. CONCLUSION: the three genetic syndromes exhibited distinctive cognitive, behavioral, and psychiatric patterns. .

OBJETIVO: investigar o perfil cognitivo e comportamental, sintomas e transtornos psiquiátricos em crianças com três diferentes síndromes genéticas, com antecedentes socioculturais e socioeconômicos semelhantes. MÉTODOS: trinta e quatro crianças, entre 6 e 16 anos, com as síndromes de Williams-Beuren (n = 10), de Prader-Willi (n = 11) e do X-Frágil (n = 13), dos ambulatórios de Psiquiatria Infantil e Genética Médica, foram avaliadas cognitivamente pela Escala Wechsler de Inteligência para Crianças (WISC-III). Posteriormente, o QI total, o QI Verbal, o QI de Execução, os escores ponderados dos subtestes e a frequência de sintomas e transtornos psiquiátricos foram comparados entre as síndromes. RESULTADOS: diferenças significativas foram encontradas entre as síndromes quanto ao QI Verbal e os subtestes verbais e de execução. A análise Post-hoc demonstrou que os escores dos subtestes vocabulário e compreensão foram significativamente superiores na síndrome de Williams-Beuren em relação às síndromes de Prader-Willi e do X-Frágil, e os escores dos subtestes cubos e armar objetos foram significativamente superiores na síndrome de Prader-Willi em relação às síndromes de Williams-Beuren e do X-Frágil. Além disso, houve diferença significativa entre as síndromes quanto às características comportamentais e os sintomas psiquiátricos. O grupo com síndrome de Prader-Willi apresentou maior frequência de hiperfagia e comportamentos autolesivos. Já o grupo com síndrome do X-Frágil apresentou maior frequência do déficit da interação social. Esta diferença quase alcançou a significância estatística. CONCLUSÃO: as três síndromes genéticas ...

Assessment of Response to Lithium Maintenance Treatment in Bipolar Disorder: A Consortium on Lithium Genetics (ConLiGen) Report.

OBJECTIVE: The assessment of response to lithium maintenance treatment in bipolar disorder (BD) is complicated by variable length of treatment, unpredictable clinical course, and often inconsistent compliance. Prospective and retrospective methods of assessment of lithium response have been proposed in the literature. In this study we report the key phenotypic measures of the "Retrospective Criteria of Long-Term Treatment Response in Research Subjects with Bipolar Disorder" scale currently used in the Consortium on Lithium Genetics (ConLiGen) study. MATERIALS AND METHODS: Twenty-nine ConLiGen sites took part in a two-stage case-vignette rating procedure to examine inter-rater agreement [Kappa (κ)] and reliability [intra-class correlation coefficient (ICC)] of lithium response. Annotated first-round vignettes and rating guidelines were circulated to expert research clinicians for training purposes between the two stages. Further, we analyzed the distributional properties of the treatment response scores available for 1,308 patients using mixture modeling. RESULTS: Substantial and moderate agreement was shown across sites in the first and second sets of vignettes (κ = 0.66 and κ = 0.54, respectively), without significant improvement from training. However, definition of response using the A score as a quantitative trait and selecting cases with B criteria of 4 or less showed an improvement between the two stages (ICC1 = 0.71 and ICC2 = 0.75, respectively). Mixture modeling of score distribution indicated three subpopulations (full responders, partial responders, non responders). CONCLUSIONS: We identified two definitions of lithium response, one dichotomous and the other continuous, with moderate to substantial inter-rater agreement and reliability. Accurate phenotypic measurement of lithium response is crucial for the ongoing ConLiGen pharmacogenomic study.

God‘s eyes and the schizophrenic hands: listening to a psychiatric patient

This article describes the intriguing case of a young female patientfirst seen in the emergency room and then followed up at the psychiatricoutpatient facility of the General Hospital at UNICAMP, Brazil. Thecooperation that ensued between psychiatrists and a psychoanalyst toreach a psychopathological diagnosis is also presented here. Thedifferential diagnosis is discussed within a psychiatric framework andthen contributions from listening to the patient’s free associations relatedto the clarification of her psychopathology are described. The clinicalcollaboration between psychiatry and psychoanalysis proved effective inthis case as a clinical method for approaching the patient.AU

Anorexia nervosa and Wernicke-Korsakoff syndrome: a case report.

INTRODUCTION: Wernicke's encephalopathy is an acute, potentially fatal, neuropsychiatric syndrome resulting from thiamine deficiency. The disorder is still greatly under-diagnosed, and failure to promptly identify and adequately treat the condition can lead to death or to the chronic form of the encephalopathy - Korsakoff's syndrome. Wernicke's encephalopathy has traditionally been associated with alcoholism but, in recent years, there has been an increase in the number of clinical settings in which the disorder is observed. CASE PRESENTATION: We report the case of a 45-year-old Caucasian woman who arrived at the emergency room presenting signs of marked malnutrition and mental confusion, ataxic gait and ophthalmoplegia. Main laboratory test findings included low serum magnesium and megaloblastic anemia. Brain magnetic resonance imaging revealed increased T2 signal in the supratentorial paraventricular region, the medial regions of the thalamus and the central and periaqueductal midbrain. The diagnosis of Wernicke's encephalopathy was made at once and immediate reposition of thiamine and magnesium was started. The patient had a long history of recurrent thoughts of being overweight, severe self-imposed diet restrictions and self-induced vomiting. She had also been drinking gin on a daily basis for the last eight years. One day after admittance the acute global confusional state resolved, but she presented severe memory deficits and confabulation. After six months of outpatient follow-up, memory deficits remained unaltered. CONCLUSION: In this case, self-imposed long-lasting nutritional deprivation is thought to be the main cause of thiamine deficiency and subsequent encephalopathy, but adjunct factors, such as magnesium depletion and chronic alcohol misuse, might have played an important role, especially in the development of Korsakoff's syndrome. The co-morbidity between eating disorders and substance abuse disorders has emerged as a significant health issue for women, and the subgroup of patients with anorexia nervosa who also misuse alcohol is probably at a particular risk of developing Wernicke-Korsakoff syndrome. The present case report highlights this relevant issue.
