As raízes do trauma: uma revisão sobre a história do psicotraumatismo / The roots of trauma: a review of the history of psychotrauma

Resumo A percepção do papel do trauma psicológico na origem de problemas psiquiátricos aumentou e diminuiu ao longo da história da psiquiatria. Com a concepção do transtorno de estresse pós-traumático (TEPT), entretanto, as sociedades ocidentais presenciaram uma profunda expansão do discurso do traumatismo na interpretação de experiências humanas devastadoras, como catástrofes, genocídios, desastres e epidemias. A partir de revisão bibliográfica integrativa, este artigo analisa alguns dos determinantes históricos e epistemológicos que fundamentam o surgimento da memória traumática e o estabelecimento do trauma como campo semântico que orienta respostas clínicas e estratégias políticas no campo das ciências humanas e da saúde.

Abstract Perceptions of the importance of the role of psychological trauma in the origins of psychiatric problems have oscillated throughout the history of psychiatry. However, since the conception of post-traumatic stress disorder (PTSD), western societies have witnessed a marked expansion of the discourse of trauma in the interpretation of devastating human experiences like catastrophes, genocides, disasters, and epidemics. Through an integrative literature review, this article analyzes some of the historical and epistemological determinants behind the emergence of traumatic memory and the establishment of trauma as a semantic field that orients clinical responses and political strategies in the field of the humanities and the health sciences.

Evidence for the beneficial effect of ketamine in the treatment of patients with post-traumatic stress disorder: A systematic review and meta-analysis.

Post-traumatic stress disorder (PTSD) is an anxiety disorder with manifestations somatic resulting from reliving the trauma. The therapy for the treatment of PTSD has limitations, between reduced efficacy and "PTSD pharmacotherapeutic crisis". Scientific evidence has shown that the use of ketamine has benefits for the treatment of depressive disorders and other symptoms present in PTSD compared to other conventional therapies. Therefore, this study aims to analyze the available evidence on the effect of ketamine in the treatment of post-traumatic stress. The systematic review and the meta-analysis were conducted following PRISMA guidelines and RevManager software, using randomized controlled trials and eligible studies of quality criteria for data extraction and analysis. The sample design evaluated included the last ten years, whose search resulted in 594 articles. After applying the exclusion criteria, 35 articles were selected, of which 14 articles were part of the sample, however, only six articles were selected the meta-analysis. The results showed that the ketamine is a promising drug in the management of PTSD with effect more evident performed after 24 h evaluated by MADRS scale. However, the main limitations of the present review demonstrate that more high-quality studies are needed to investigate the influence of therapy, safety, and efficacy.

The effect of trauma type on the severity of Post-Traumatic Stress Disorder (PTSD) symptoms

Abstract Objective: The high prevalence of trauma exposure calls for detailed research on how trauma type affects the development of Post-Traumatic Stress Disorder (PTSD). Therefore, the aim of our study was to investigate the effects of the type of trauma on the severity of symptoms, anxiety, depression, and dissociative experiences in the PTSD patient population. Method: The sample of the study consists of 80 volunteer PTSD patients (20 sexual trauma, 20 work accidents, 20 traffic accidents and 20 combat related trauma). Once the severity of symptoms was determined in all subjects by the Clinician-Administered PTSD Scale (CAPS), Beck Depression Inventory, Beck Anxiety Inventory and Dissociative Experiences Scale (DES) were applied. Results: A statistically significant difference were found between trauma types with regard to age, time without treatment, and the total and subscale scores obtained in DES and CAPS. It was found that in the group that has PTSD diagnosis related to sexual trauma, the length of the time without treatment, DES and CAPS scores. Conclusion: The study we conducted showed that PTSD continued more severe and resistant after a sexual trauma. Moreover, specific type of trauma was significant in PTSD patients.

Estrés postraumático en escolares a 8 meses del 27F / Post-traumatic stress disorder in children eight months after february 27, 2010

Introduction: there are several epidemiological studies regarding the incidence of post-traumatic stress disorder (PTSD) in children exposed to natural disasters. Objective: to describe the prevalence of PTSD in a school-age population in a coastal town from the Maule Region, 8 months after the earthquake/tsunami in february 2010, and to compare differences among PTSD groups of symptom (re-experiencing, avoidance and activation) according to demographic variables such as age, grade, gender and family type. Methodology: the Child PTSD Symptom Scale (CPSS), validated in Chile in 2009, was used in 89 children between 3rd and 6th grade, corresponding to 94.7 percent of the children enrolled in the local school in such classes. Data are analyzed by gender, age, grade and type of family. 89 surveys were applied, 59.6 percent were male and 40.4 percent female aged 8-13. Results: 40.4 percent of children had symptoms consistent with PTSD, with higher incidence in women and younger children; the most significant association among women was age. Both groups (women and young children) presented the highest scores on all group of symptoms. There were no differences by type of family. Conclusions: the incidence of PTSD measured by CPSS scale in the study population was 40.4 percent, considered to be among the highest percentages reported in the international literature.

Introducción: existen diversos datos epidemiológicos respecto a la incidencia de Trastorno por Estrés Pos-traumático (TEPT) en niños expuestos a desastres naturales. Objetivo: describir la prevalencia de TEPT en una población infantil escolarizada de una localidad costera de la Región del Maule después de 8 meses de ocurrido el terremoto/maremoto de febrero/2010, y comparar las diferencias entre grupos de síntomas del TEPT (reexperimentación, evitación y activación) según variables demográficas, como edad, curso, sexo y tipo de familia.

Resultados: el 40,4 por ciento del total de niños tuvo una evaluación compatible con TEPT, con mayor incidencia en mujeres y niños de menor edad, siendo la edad un factor de asociación significativa en las mujeres. Ambos grupos (mujeres y niños más pequeños) presentaron mayores puntajes en todos los grupos sintomáticos. No se encontraron diferencias según el tipo de familia. Conclusiones: la incidencia de TEPT medida a través de la escala CPSS en la población estudiada fue de 40.4 por ciento, encontrándose entre las más altas reportadas en la bibliografía internacional.
