El conflicto armado en Colombia se presenta en zonas rurales y urbanas; sin embargo, en municipios y territorios distantes, el fenómeno del desplazamiento forzado incide en la vida de la población civil, planteando nuevos escenarios a nivel social. Por esta razón, hay impactos a nivel humanitario, social, económico, político, cultural y psicológico en las poblaciones más vulnerables, como lo son los niños desplazados; con importantes incidencias en salud pública, específicamente en salud mental. El propósito de este artículo de revisión es describir la situación actual de las condiciones de salud mental, desarrollar el concepto de resiliencia y describir la interacción que existe entre el trastorno de estrés postraumático de la primera infancia en condiciones de desplazamiento y la atención psicosocial en las políticas públicas para éste grupo poblacional. Teniendo en cuenta que en éste hecho social han intervenido organizaciones civiles, religiosas, no gubernamentales y estatales, se resalta la importancia de desarrollar un trabajo vinculante y cohesionado entre estas organizaciones.

El dolor es un problema importante para los pacientes hospitalizados en las UCI porque genera malestar y distrés. Además, la investigación ha demostrado que en algunos pacientes críticos el dolor agudo puede persistir después de alta y convertirse en crónico. La gestión eficaz del dolor en pacientes críticos requiere un enfoque interdisciplinario, que incorpore la visión y trabajo de expertos que representan una amplia variedad de especialidades clínicas. Así, la utilización de la intervención psicológica en el tratamiento del dolor es una parte integral de un enfoque global. Basado en una revisión de la evidencia científica, se identifican y señalan: (1) los tipos de dolor más comunes; (2) las características del dolor; (3) las patologías más frecuentes asociadas con la presencia de dolor; (4) los procedimientos que generan dolor en la UCI; (5) los métodos de evaluación del dolor; (6) la intervención del mismo y; (7) la contribución del psicólogo en la evaluación y manejo del dolor con el paciente, los familiares y los profesionales de la salud. La revisión realizada indica que los procesos psicológicos influyen tanto en la experiencia del dolor como en los resultados del tratamiento, por lo tanto la integración de los principios psicológicos en el tratamiento del dolor parecen tener potencial mejora de los resultados beneficiando la salud del paciente.

El trasplante de órganos y/o tejidos es considerado como una opción terapéutica viable para el tratamiento tanto de enfermedades crónicas o en estadios terminales, como de afectaciones no vitales, pero que generen una disminución en la calidad de vida percibida por el paciente. Este procedimiento, de carácter multidimensional, está compuesto por 3 actores principales: el donante, el órgano/tejido, y el receptor. Si bien un porcentaje significativo de investigaciones y planes de intervención han girado en torno a la dimensión biológica del trasplante, y a la promoción de la donación; el interés por la experiencia psicosocial y la calidad de vida de los receptores en este proceso ha aumentado durante la última década. En relación con esto, la presente monografía se plantea como objetivo general la exploración de la experiencia y los significados construidos por los pacientes trasplantados, a través de una revisión sistemática de la literatura sobre esta temática. Para ello, se plantearon unos objetivos específicos derivados del general, se seleccionaron términos o palabras claves por cada uno de estos, y se realizó una búsqueda en 5 bases de datos para revistas indexadas: Ebsco Host (Academic Search; y Psychology and Behavioral Sciences Collection); Proquest; Pubmed; y Science Direct. A partir de los resultados, se establece que si bien la vivencia de los receptores ha comenzado a ser investigada, aún es necesaria una mayor exploración sobre la experiencia de estos pacientes; exploración que carecería de objetivo si no se hiciera a través de las narrativas o testimonios de los mismos receptores

Introducción: Ingresar a la UCI no es una experiencia exclusiva del paciente; implica e involucra directamente a la familia, en aspectos generadores de estrés, estrategias de afrontamiento, temores, actitudes y expectativas, la participación de la familia en el cuidado y el rol del psicólogo. Objetivo: Revisar de los antecedentes teóricos y empíricos sobre la experiencia de la familia en UCI. Metodología: Se revisaron 62 artículos indexados en bases de datos. Resultados: la UCI es algo desconocido tanto para el paciente como para la familia, por esto este entorno acentúa la aparición de síntomas ansiosos, depresivos y en algunos casos estrés post traumático. La muerte es uno de los principales temores que debe enfrentar la familia. Con el propósito de ajustarse a las demandas de la UCI, los familiares exhiben estrategias de afrontamiento enfocadas principalmente en la comunicación, el soporte espiritual y religioso y la toma de decisiones. El cuidado centrado en la familia permite una mejor comunicación, relación con el paciente y personal médico. El papel del psicólogo es poco explorado en el espacio de la UCI, pero este puede promover estrategias de prevención y de rehabilitación en el paciente y su grupo familiar. Discusión: es importante tener en cuenta que la muerte en UCI es una posibilidad, algunos síntomas como ansiedad, depresión pueden aparecer y mantenerse en el tiempo, centrar el cuidado en la familia permite tomar las decisiones basados en el diagnóstico y pronóstico y promueve expectativas realistas. Conclusiones: temores, expectativas, actitudes, estrategias de afrontamiento, factores generadores de estrés permiten explicar y comprender la experiencia de la familia del paciente en UCI.

This study aims to: 1) assess the proportion of General Practioners (GPs) who are aware of or who have read the National Institute for Health and Clinical Excellence (NICE; 2005a) guidelines for Obsessive Compulsive Disorder (OCD), 2) compare this with the proportion of other mental health disorders found by previous research and 3) establish the prevalence of OCD in primary care. Questionnaires were sent to all GPs (n = 795) and practice managers (n = 157) in Berkshire and Buckinghamshire, South East England. These contained 19 questions and took 5 min to complete. After the first set of responses, larger practices were visited and telephoned to encourage further responses. The response rates were 10.1% from GPs and 19.1% from practice managers. In all, 48.7% of the GPs were aware of the NICE guidelines for OCD and 30.3% reported that they had read them – higher than for Post-Traumatic Stress Disorder, but lower than for depression. Of registered patients, 0.2% were diagnosed with OCD, lower than the 1.1% found in epidemiological studies.

Extinction following positively reinforced operant conditioning reduces response frequency, at least in part through the aversive or frustrative effects of non-reinforcement. According to J.A. Gray's theory, non-reinforcement activates the behavioural inhibition system which in turn causes anxiety. As predicted, anxiolytic drugs including benzodiazepines affect the operant extinction process. Recent studies have shown that reducing GABA-mediated neurotransmission retards extinction of aversive conditioning. We have shown in a series of studies that anxiolytic compounds that potentiate GABA facilitate extinction of positively reinforced fixed-ratio operant behaviour in C57B1/6 male mice. This effect does not occur in the early stages of extinction, nor is it dependent on cumulative effects of the compound administered. Potentiation of GABA at later stages has the effect of increasing sensitivity to the extinction contingency and facilitates the inhibition of the behaviour that is no longer required. The GABAergic hypnotic, zolpidem, has the same selective effects on operant extinction in this procedure. The effects of zolpidem are not due to sedative action. There is evidence across our series of experiments that different GABA-A subtype receptors are involved in extinction facilitation and anxiolysis. Consequently, this procedure may not be an appropriate model for anxiolytic drug action, but it may be a useful technique for analysing the neural bases of extinction and designing therapeutic interventions in humans where failure to extinguish inappropriate behaviours can lead to pathological conditions such as post-traumatic stress disorder.

Social anxiety disorder is one of the most persistent and common of the anxiety disorders, with lifetime prevalence rates in Europe of 6.7% (range 3.9-13.7%).1 It often coexists with depression, substance use disorder, generalised anxiety disorder, panic disorder, and post-traumatic stress disorder.2 It can severely impair a person’s daily functioning by impeding the formation of relationships, reducing quality of life, and negatively affecting performance at work or school. Despite this, and the fact that effective treatments exist, only about half of people with this condition seek treatment, many after waiting 10-15 years.3 Although about 40% of those who develop the condition in childhood or adolescence recover before adulthood,4 for many the disorder persists into adulthood, with the chance of spontaneous recovery then limited compared with other mental health problems. This article summarises the most recent recommendations from the National Institute for Health and Care Excellence (NICE) on recognising, assessing, and treating social anxiety disorder in children, young people, and adults.5

The relationship between hallucinations and life events is a topic of significant clinical importance. This review discusses the extent to which auditory and visual hallucinations may be directly related to traumatic events. Evidence suggests that intrusive images occur frequently within individuals who also report hallucinatory experiences. However, there has been limited research specifically investigating the extent to which hallucinations are the re-experiencing of a traumatic event. Our current theoretical understanding of these relationships, along with methodological difficulties associated with research in this area, are considered. Recent clinical studies, which adopt interventions aimed at the symptoms of post-traumatic stress disorder in people diagnosed with a psychotic disorder, are reviewed. There is a need for the development of evidence-based interventions in this area.

Focusing on The Act of Killing, this chapter examines how an “ethics of realism” operates on three key cinematic arenas: genre, authorship and spectatorship. As far as genre is concerned, the film’s realist commitment emerges from where it is least expected, namely from Hollywood genres, such as the musical, the film noir and the western, which are used as documentary, that is to say, as a fantasy realm where perpetrators can confess to their crimes without restraints or fear of punishment, but which nonetheless retains the evidentiary weight of the audiovisual medium. Authorship, in turn, translates as Oppenheimer’s unmistakable auteur signature through his role of self-confessed “infiltrator” who disguises as a sympathiser of the criminals in order to gain first-hand access to the full picture of their acts. One of them, the protagonist Anwar Congo, is clearly affected by post-traumatic stress disorder, and his repetitive reliving of his killings is made to flare up in front of the camera so as to bring back the dead to the present time in their material reality, through his own body, including a harrowing scene of the actor’s unpredictable and uncontrollable retching as he re-enacts the killing of his victims through strangulation. Finally, in the realm of spectatorship, the usual process of illusionistic identification on the part of the spectator is turned onto its head by means of disguising these criminals as amateur filmmakers, led to shoot, act within, and then watch their own film within the film so as to force them to experience beyond any illusion the suffering they had caused.

Syftet med denna litteraturstudie var att belysa ämnet barn och katastrofer, som hur barn reagerar efter traumatiska händelser, hur de utvecklar Post- Traumatic Stress Disorder (PTSD), hur PTSD behandlas samt hur vårdpersonal kan hjälpa barn på bästa sätt. Studien var en systematisk litteraturstudie. Litteraturen söktes via Elin@dalarna, Pub Med och DOAJ. Sökord som användes för att få fram relevanta artiklar var: ”adaption”, ”care”, ”catastrophe”, ”children”, ”child”, ”disasters”, ”help”, ”natural disaster”, ”PTSD”, ”react”, ”trauma”. Dessa ord användes ett och ett samt i kombination med varandra. De vetenskapliga artiklarna som användes kvalitetsbedömdes med en kombinerad granskningsmall av Forsberg och Wengström (2003) samt Willman och Stoltz (2002) granskningsmallar för kvalitativa och kvantitativa studier. Denna granskning resulterade i ett urval av 16 vetenskapliga artiklar som var publicerade mellan1990 och 2006 och var skrivna på svenska eller engelska. Sökorden fanns med i artikelns titel eller abstract, samt att dess innehåll skulle besvara frågeställningarna som fanns. De studier som granskades i denna uppsats visade att barn reagerar väldigt olika beroende på deras sociala liv och levnadsstandard, samt hur svårt drabbade de blivit av naturkatastrofen. Barns första reaktioner efter en naturkatastrof var ofta ilska och aggressioner över det inträffade, barnen anklagade ofta sig själva för det inträffade. Barn som levde under sociala missförhållande, utan föräldrar, hem och vänner löpte högre risk att få symtom på PTSD, och det var vanligare att flickor fick symtom än pojkar. De vanligaste behandlingsmetoderna för symtom av PTSD var kognitiv beteendeterapi och läkemedel. Den viktigaste hjälpen för barn som upplevt en naturkatastrof var att hjälpa dem tillbaka till det vardagliga livet.

Several lines of evidence converge to the idea that rapid eye movement sleep (REMS) is a good model to foster our understanding of psychosis. Both REMS and psychosis course with internally generated perceptions and lack of rational judgment, which is attributed to a hyperlimbic activity along with hypofrontality. Interestingly, some individuals can become aware of dreaming during REMS, a particular experience known as lucid dreaming (LD), whose neurobiological basis is still controversial. Since the frontal lobe plays a role in self-consciousness, working memory and attention, here we hypothesize that LD is associated with increased frontal activity during REMS. A possible way to test this hypothesis is to check whether transcranial magnetic or electric stimulation of the frontal region during REMS triggers LD. We further suggest that psychosis and LD are opposite phenomena: LD as a physiological awakening while dreaming due to frontal activity, and psychosis as a pathological intrusion of dream features during wake state due to hypofrontality. We further suggest that LD research may have three main clinical implications. First, LD could be important to the study of consciousness, including its pathologies and other altered states. Second, LD could be used as a therapy for recurrent nightmares, a common symptom of depression and post-traumatic stress disorder. Finally, LD may allow for motor imagery during dreaming with possible improvement of physical rehabilitation. In all, we believe that LD research may clarify multiple aspects of brain functioning in its physiological, altered and pathological states.

Obsessive-compulsive disorder (OCD) has clinical features that overlap in various degrees with many other mental disorders. As a result, the differential diagnosis sometimes can be difficult. This review briefly summarizes the phenomenologic similarities and differences between OCD and the following disorders: depression, phobias, hypochondriasis and body dysmorphic disorder, Tourette syndrome and tic disorder, obsessive-compulsive personality disorder, impulse control and eating disorders, generalized anxiety, panic and post-traumatic stress disorders, and delusional and schizophrenic disorders. The accurate diagnosis is essential for adequate treatment planning and management.
