Trauma cerrado de aorta torácica, desde el servicio de urgencias hasta el quirófano: revisión narrativa / Blunt trauma of the thoracic aorta, from the emergency department to the operating room: narrative review / Trauma contuso da aorta torácica: do pronto-socorro ao centro cirúrgico, uma revisão narrativa

El trauma es la principal causa de muerte de la población en edad productiva. El abordaje del trauma torácico cerrado todavía es un desafío para el médico de urgencias. Aunque no es una entidad frecuente, se asocia con una alta mortalidad y resultados adversos. El diagnóstico del trauma cerrado de aorta torácica (LCAT) requiere un alto índice de sospecha, dado que los signos y síntomas no son específicos de esta enfermedad (dolor torácico, dolor interescapular, disnea, disfagia, estridor, disfonía). Es importante resaltar que la ausencia de inestabilidad hemodinámica no debe descartar una lesión aórtica. Para su diagnóstico imagenológico se debe tener en cuenta que los rayos X de tórax no tienen el rendimiento adecuado, el patrón de referencia es la angiotomografía y el ecocardiograma transesofágico (ETE) constituye una opción diagnóstica. El manejo incluye líquidos endovenosos y antihipertensivos como medida transitoria, manejo quirúrgico definitivo y, en algunos casos, manejo expectante o diferido. Los pacientes inestables o con signos de ruptura inminente deben ser llevados de manera inmediata a cirugía. El manejo quirúrgico temprano ha impactado en la mortalidad. A pesar de los avances en las técnicas quirúrgicas, la técnica quirúrgica abierta documenta mayor tasa de mortalidad que el manejo endovascular, el cual tiene numerosas ventajas al ser poco invasivo. Esta es una revisión narrativa que destaca algunos aspectos clave sobre los mecanismos de lesión, diagnóstico y manejo inicial del trauma cerrado aorta torácica. Por último, se propone un algoritmo de abordaje de trauma de aorta.

Trauma is the leading cause of death in the productive-age population. Addressing blunt chest trauma is still a challenge for the emergency physician. Although it is not a common entity, it is associated with high mortality and adverse outcomes. The diagnosis of blunt thoracic aortic trauma (LCAT) requires a high index of suspicion, given that the signs and symptoms are not specific to this disease (chest pain, interscapular pain, dyspnea, dysphagia, stridor, dysphonia). It is important to highlight that the absence of hemodynamic instability should not rule out aortic injury. For its imaging diagnosis, it must be taken into account that chest X-rays do not have adequate performance; the reference standard is angiotomography and transesophageal echocardiography (TEE) is a diagnostic option. Management includes intravenous fluids and antihypertensives as a temporary measure, definitive surgical management and, in some cases, expectant or deferred management. Unstable patients or patients with signs of imminent ruptura should be taken immediately to surgery. Early surgical management has impacted mortality. Despite advances in surgical techniques, the open surgical technique documents a higher mortality rate than endovascular management, which has numerous advantages as it is minimally invasive. This is a narrative review that highlights some key aspects about the mechanisms of injury, diagnosis and initial management of blunt thoracic aortic trauma. Finally, an algorithm for addressing aortic trauma is proposed.

O trauma é a principal causa de morte na população em idade produtiva. Abordar o trauma torácico contuso ainda é um desafio para o médico emergencista. Embora não seja uma entidade comum, está associada a alta mortalidade e resultados adversos. O diagnóstico de trauma fechado de aorta torácica (TACE) requer alto índice de suspeição, visto que os sinais e sintomas não são específicos desta doença (dor torácica, dor interescapular, dispneia, disfagia, estridor, disfonia). É importante ressaltar que a ausência de instabilidade hemodinâmica não deve descartar lesão aórtica. Para seu diagnóstico por imagem deve-se levar em consideração que a radiografia de tórax não apresenta desempenho adequado; o padrão de referência é a angiotomografia e a ecocardiografia transesofágica (ETE) é uma opção diagnóstica. O manejo inclui fluidos intravenosos e anti-hipertensivos como medida temporária, manejo cirúrgico definitivo e, em alguns casos, manejo expectante ou diferido. Pacientes instáveis ou com sinais de ruptura iminente devem ser encaminhados imediatamente para cirurgia. O manejo cirúrgico precoce impactou a mortalidade. Apesar dos avanços nas técnicas cirúrgicas, a técnica cirúrgica aberta documenta maior taxa de mortalidade do que o manejo endovascular, que apresenta inúmeras vantagens por ser minimamente invasivo. Esta é uma revisão narrativa que destaca alguns aspectos-chave sobre os mecanismos de lesão, diagnóstico e manejo inicial do trauma contuso da aorta torácica.

The interaction of the oxytocin receptor gene and child abuse subtypes on social cognition in euthymic patients with bipolar disorder type I.

Background: Most studies on cognitive impairment in bipolar disorder have neglected the role of early stress, despite the high frequency of childhood maltreatment in this clinical group. The aim of this study was to establish a connection between a history of emotional, physical, and sexual abuse in childhood and social cognition (SC) in patients with bipolar disorder type I (BD-I) in euthymia, and to test a possible moderating effect of the single nucleotide polymorphism rs53576 in the oxytocin receptor gene (OXTR). Methods: One hundred and one participants were included in this study. History of child abuse was evaluated using the Childhood Trauma Questionnaire-Short Form. Cognitive functioning was appraised using The Awareness of Social Inference Test (social cognition). The interaction effect between the independent variables OXTR rs53576 (AA/AG and GG) and the absence or presence of any one type of child maltreatment or a combination of types was analyzed using a generalized linear model regression. Results: BD-I patients who had been victims of physical and emotional abuse in childhood and were carriers of the GG genotype at OXTR rs53576 displayed greater SC alterations, specifically in emotion recognition. Discussion: This gene-environment interaction finding suggests a differential susceptibility model of a genetic variants that can be plausibly associated with SC functioning and might help to identify at-risk clinical subgroups within a diagnostic category. Future research aimed at testing the interlevel impact of early stress constitutes an ethical-clinical duty given the high rates of childhood maltreatment reported in BD-I patients.

The Effect of Child Trauma on the Relation between Psychological Well-Being and Depressive Symptoms in Chilean University Students.

(1) Background: There is consistent evidence of the impact of early adverse experiences on mental health in adulthood, especially as a risk factor for depression. However, their influence on positive aspects of mental health such as well-being has been less extensively studied. Therefore, this study aims to investigate the effect of traumatic childhood experiences on the relationship between depression and psychological well-being in a sample of university students. (2) Methods: The Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Beck Depression Inventory (BDI-IA), and Ryff's psychological well-being scale were administered to 700 Chilean university students. Several regression models were used to analyze the interaction between variables, with multivariate SEM being applied to hierarchize the relationships found. (3) Results: Emotional Neglect and Abuse stand out as the types of maltreatment with the greatest impact on mental health, associated first with a decrease in the self-acceptance dimension of psychological well-being and then with depressive symptomatology in adulthood. (4) Conclusions: Results provide evidence that early trauma has an important impact on mental health, increasing the risk of depression, however, its impact is greater on positive aspects of health, such as self-acceptance, a fundamental element in the construction of psychological well-being.

Potential epigenetic mechanisms in psychotherapy: a pilot study on DNA methylation and mentalization change in borderline personality disorder.

Genetic and early environmental factors are interwoven in the etiology of Borderline Personality Disorder (BPD). Epigenetic mechanisms offer the molecular machinery to adapt to environmental conditions. There are gaps in the knowledge about how epigenetic mechanisms are involved in the effects of early affective environment, development of BPD, and psychotherapy response. We reviewed the available evidence of the effects of psychotherapy on changes in DNA methylation and conducted a pilot study in a sample of 11 female adolescents diagnosed with BPD, exploring for changes in peripheral DNA methylation of FKBP5 gene, which encodes for a stress response protein, in relation to psychotherapy, on symptomatology and underlying psychological processes. For this purpose, measures of early trauma, borderline and depressive symptoms, psychotherapy outcome, mentalization, and emotional regulation were studied. A reduction in the average FKBP5 methylation levels was observed over time. Additionally, the decrease in FKBP5 methylation observed occurred only in those individuals who had early trauma and responded to psychotherapy. The results suggest an effect of psychotherapy on epigenetic mechanisms associated with the stress response. The finding that epigenetic changes were only observed in patients with early trauma suggests a specific molecular mechanism of recovery. The results should be taken with caution given the small sample size. Also, further research is needed to adjust for confounding factors and include endocrinological markers and therapeutic process variables.

The Clinical Relevance of Interdisciplinary Research on Affect Regulation in the Analytic Relationship.

After more than a century of existence, theoretical development, research, and clinical practice within the psychoanalytic movement have consistently demonstrated that psychoanalysis is not a unitary and autonomous discipline. This has been evidenced by the various ways in which psychoanalytic thought and practice have been informed by and have established a dialogue-more or less fruitful-with related disciplines (neurosciences, developmental psychology, psychotherapy research, attachment theory and research, feminism, philosophy). This dialogue has contributed to a better understanding of the functioning of the human psyche, and therefore of the analytic process, informing clinical interventions. In turn, it has enriched research on psychoanalytic practice and process, underlining the fact that research in psychoanalysis is fundamentally about clinical practice. Since its origins, psychoanalysis has made explicit the work on the patient-analyst relationship as the terrain in which the analytic process unfolds. For its part, research in psychotherapy has demonstrated the relevance of the therapeutic relationship for the good development and outcome of any psychotherapeutic process. This supports the argument that research in clinical psychoanalysis should be research on the impact of the analyst interventions on the analyst-patient relationship. In this context, a central element of what happens in the analytic relationship refers to affect communication and therefore, affect regulation, which is manifested in the transferential and counter-transferential processes, as well as in the therapeutic bond. On the other hand, affective regulation is found at the crossroads of etiopathogenesis, complex personality models and psychopathology, allowing the understanding of human functioning and the staging of these configurations in the patient-analyst relationship. In this way, research on affective regulation in the analytic process is proposed as a path that exemplifies interdisciplinary research and scientific pluralism from which psychoanalysis enriches and progresses as a discipline. The case of a line of research on affective regulation in psychoanalytic psychotherapy is illustrated. The need to resort to other disciplines, as well as the translational value of our research and its clinical usefulness, is discussed.

[History of child abuse among patients with bipolar disorders]. / El maltrato infantil y su rol en el curso clínico de pacientes con trastorno bipolar.

BACKGROUND: A history of child abuse is common and has a significant impact in the clinical course of patients diagnosed with bipolar disorders (BD). AIMS: To assess the frequency of child abuse experiences in patients BD type I and to evaluate its association with clinical course and cognitive functioning variables. MATERIAL AND METHODS: 117 patients with BD aged 45 ± 14 years (66% women) answered the Childhood Trauma Questionnaire (CTQ). The clinical course (illness onset, history of suicide attempts and number of hospitalizations) was obtained from medical records. Cognitive functioning was evaluated through social and non-social cognition tasks. RESULTS: 64% of participants reported some type of child abuse. This variable was associated with an early onset of the disease (Odds ratio (OR) = 3.3; p < 0.02), increased risk of suicide attempts (OR = 2.4; p < 0.04) and specific disturbances in social cognitive tasks. CONCLUSIONS: Our study supports evidence of a common history of child abuse in patients with BD. Although child abuse predicts a worse clinical course, major clinical practice guidelines, as well as research designs, do not highlight this evidence.

Walking the middle ground between hermeneutics and science: A research proposal on psychoanalytic process.

In 100 years of clinical research and 40 years of empirical research, the concept of psychoanalytic process continues to elude a consensual definition, probably because the problem and methodology must be approached in a different way. This article outlines the empirical implications of the epistemological model exposed in a previous article, by proposing a scientific, innovative, and clinically sensitive research programme for the study of psychoanalytic process. This proposal is an attempt at developing psychotherapy research that is founded on psychoanalytic hypotheses derived from a two-person psychology. The research programme focuses on the interactional nature of the analytical work, and on the relationship between the implicit (unconscious) and the explicit (conscious) levels of the analytic endeavour. The authors propose that this research programme be articulated around three methodological approaches: (1) the use of systematic case studies; (2) the adoption of the events paradigm for accessing the salient phenomena of the psychoanalytic process; and (3) a micro-analytic approach to the specific phenomena occurring within relevant sequences of interaction. These ideas are illustrated with a description of the micro-analysis of a clinical case. This article is intended to contribute to a constructive dialogue between psychoanalytic practice and psychotherapy research.

[Depressive symptomatology and psychological well-being among Chilean university students]. / Sintomatologia depresiva y bienestar psicológico en estudiantes universitarios chilenos.

BACKGROUND: Quality of life and psychological well-being are readily hampered by depression. The changes that students face during college life impact their psychological health and well-being, including the emergence of mental health problems like depression Aim: To determine the relationship between depressive symptoms, sociodemographic parameters and psychological well-being in undergraduate university students. MATERIAL AND METHODS: Five hundred eighty university students of both sexes, from the Metropolitan and IX Regions of Chile answered the Beck Depression Inventory (BDI-IA) and the Ryff's psychological well-being scale. RESULTS: Twenty eight percent of respondents had clinically significant depressive symptoms, and these were more frequent in women. There was an inverse and statistically significant relationship between psychological well-being and depressive symptoms. This fact was especially marked in dimensions of autonomy, positive relationships with others and purpose in life. CONCLUSIONS: There is a high frequency of depressive symptoms among these students. We discuss whether psychological well-being and depressive symptomatology represent two extremes within a continuum or they are two independent dimensions that can account for differential causal mechanisms linked to mental health and illness.

Síndrome opsoclonus-mioclonus-ataxia asociado con un teratoma ovárico maduro en un paciente pediátrico / Opsoclonus-mioclonus-ataxia syndrome associated with a mature ovarian teratoma in a pediatric patient

Resumen El síndrome de opsoclonus-mioclonus-ataxia es una entidad rara que cursa con síntomas motores, neurocognitivos y psiquiátricos, con frecuencia marcadamente debilitantes. El síndrome se reporta con mayor frecuencia en adultos que en niños, la etiología es variada, pero en pediatría se presenta en la mayoría de los casos como un síndrome paraneoplásico. En este contexto la neoplasia más frecuentemente asociada es el neuroblastoma. La evidencia actual apoya la tesis de que este es un síndrome mediado inmunológicamente al haberse identificado una serie de auto-anticuerpos en los pacientes afectados, y a que muchos de ellos responden a terapia inmunosupresora. La importancia del reconocimiento de este síndrome radica en que existe tratamiento médico y quirúrgico que podría mejorar el pronóstico neurológico y psiquiátrico. Presentamos el caso de una paciente que se presentó con este síndrome en nuestra institución.

Abstract The opsoclonus-myoclonus-ataxia syndrome is a rare entity that presents with motor, neurocognitive and psychiatric symptoms, often markedly de bilitating. The syndrome is reported more frequently in adults than in chil dren, the etiology is varied, but in pediatrics it occurs in most cases as a paraneoplastic syndrome. In this context, the most frequently associated neoplasm is neuroblastoma followed by gynecological tumors. The current evidence supports the thesis that this is an immune-mediated syndrome because a series of circulating autoantibodies has been described in the affected patients, in addition to many of them responding to immuno suppressive therapy. The importance of recognizing this syndrome is that there is medical/surgical treatment available that could improve the neu rological and psychiatric prognosis. Next, we present the case of a patient who presented with this syndrome in our institution.

Beyond the hermeneutic/scientific controversy: A case for a clinically sensitive empirical research paradigm in psychoanalysis.

This article is devoted to the topic of the conditions for a constructive interdisciplinary dialogue between psychoanalytic theory and practice and research in mind disciplines neighbouring psychoanalysis applied to the concept of psychoanalytic process. The first section reviews the contemporary controversy about psychoanalysis and research and the contributions that different disciplines-such as empirical research in progress in psychotherapy and psychoanalysis, in attachment and the early mother-infant relationship, and neurosciences-propose for the construction of theory in psychoanalysis. The gaps in the scientific investigation of central aspects of the psychoanalytic conception are highlighted, such as the dyadic nature of the construction of the experience in therapy and the relationship between the implicit and explicit levels of the analytic relationship. The article concludes by laying the foundations for a novel research programme for psychoanalysis that addresses the outstanding gaps.

Carcinoma escamocelular cutáneo del tronco y las extremidades: utilidad del ganglio centinela en su estadificación / Skin Squamous Cell Carcinoma of the trunk and limbs: Role of Sentinel Node Biopsy in its staging

Resumen El carcinoma escamocelular (CEC) tiene un comportamiento biológico más agresivo cuando exhibe factores de riesgo. En este grupo, se comprometen los ganglios linfáticos hasta en 21% de los casos lo que disminuye la supervivenciaa5años. El examen clínico de las cadenas ganglionares puede tener una tasa de falsos negativos cercana a 39%, determinando la necesidad de una herramienta que permita evaluar el compromiso ganglionar de un modo más preciso. La biopsia del ganglio centinela ha sido documentada en la estadificación del CEC de cabeza y cuello, y el CEC de origen anogenital, pero en estas series de casos hay un escaso número de pacientes correspondientes a CEC cutáneo del tronco y las extremidades. El objetivo de esta revisión es describir las indicaciones y la plausibilidad de estadificar la extensión ganglionar usando la biopsia de ganglio centinela en pacientes con CEC cutáneo del tronco y extremidades. © 2017 Instituto Nacional de Cancerologia.

Abstract Squamous Cell Carcinoma (SCC) is associated with a more aggressive biological behaviour in the presence of risk factors. High risk SCC may present with lymph node metastasis in 21% of patients, with the consequent reduction in overall survival. The physical examination lymph nodes can have a false-negative rate between 15% and 39%, thus requiring the need to find a new diagnostic tool that allows a more precise evaluation of lymph node involvement. Sentinel lymph node biopsy has been reported in case series of patients with head and neck SCC, and genital SCC, but there are few case reports about skin SCC of the trunk and extremities. The aim of this review is to describe the indications and feasibility of using sentinel lymph node biopsy to assess lymph node status in patients with skin SCC of trunk and limbs. © 2017 Instituto Nacional de Cancerologia.

Identification of distinct nanoparticles and subsets of extracellular vesicles by asymmetric flow field-flow fractionation.

The heterogeneity of exosomal populations has hindered our understanding of their biogenesis, molecular composition, biodistribution and functions. By employing asymmetric flow field-flow fractionation (AF4), we identified two exosome subpopulations (large exosome vesicles, Exo-L, 90-120 nm; small exosome vesicles, Exo-S, 60-80 nm) and discovered an abundant population of non-membranous nanoparticles termed 'exomeres' (~35 nm). Exomere proteomic profiling revealed an enrichment in metabolic enzymes and hypoxia, microtubule and coagulation proteins as well as specific pathways, such as glycolysis and mTOR signalling. Exo-S and Exo-L contained proteins involved in endosomal function and secretion pathways, and mitotic spindle and IL-2/STAT5 signalling pathways, respectively. Exo-S, Exo-L and exomeres each had unique N-glycosylation, protein, lipid, DNA and RNA profiles and biophysical properties. These three nanoparticle subsets demonstrated diverse organ biodistribution patterns, suggesting distinct biological functions. This study demonstrates that AF4 can serve as an improved analytical tool for isolating extracellular vesicles and addressing the complexities of heterogeneous nanoparticle subpopulations.

Vulnerability or Sensitivity to the Environment? Methodological Issues, Trends, and Recommendations in Gene-Environment Interactions Research in Human Behavior.

Research on the potential role of gene-environment interactions (GxE) in explaining vulnerability to psychopathology in humans has witnessed a shift from a diathesis-stress perspective to differential susceptibility approaches. This paper critically reviews methodological issues and trends in this body of research. Databases were screened for studies of GxE in the prediction of personality traits, behavior, and mental health disorders in humans published between January 2002 and January 2015. In total, 315 papers were included. Results showed that 34 candidate genes have been included in GxE studies. Independent of the type of environment studied (early or recent life events, positive or negative environments), about 67-83% of studies have reported significant GxE interactions, which is consistent with a social susceptibility model. The percentage of positive results does not seem to differ depending on the gene studied, although publication bias might be involved. However, the number of positive findings differs depending on the population studied (i.e., young adults vs. older adults). Methodological considerations limit the ability to draw strong conclusions, particularly as almost 90% (n = 283/315) of published papers are based on samples from North America and Europe, and about 70% of published studies (219/315) are based on samples that were also used in other reports. At the same time, there are clear indications of methodological improvements over time, as is shown by a significant increase in longitudinal and experimental studies as well as in improved minimum genotyping. Recommendations for future research, such as minimum quality assessment of genes and environmental factors, specifying theoretical models guiding the study, and taking into account of cultural, ethnic, and lifetime perspectives, are formulated.

[Clinical skills of Chilean general practitioners for the management of depressive disorders]. / Habilidades clínicas para el manejo de trastornos depresivos en médicos generales en Santiago de Chile.

BACKGROUND: Diverse and sustained efforts have been developed to improve the management of depression by general practitioners (GPs), but they have not improved treatment coverage and quality of services. AIM: To explore the level of knowledge and clinical skills to diagnose and treat depression by GPs in Primary Health Care (PHC) in the Metropolitan Area of Santiago de Chile (RM). MATERIAL AND METHODS: Theoretical knowledge (TK), diagnostic skills (DS) and treatment skills (TS) were evaluated in 56 GPs of the RM with a battery of specially designed instruments. RESULTS: In TK there were significant differences between GPs aged 31 years or less and their older counterparts and between Chilean and foreign doctors. Five percent of observed differences in TK were explained by age and nationality, respectively. Chilean GPs achieved higher scores in recognition of symptoms (RS), one of the dimensions of DS. No significant differences by age or nationality were observed for DS and TS. CONCLUSIONS: Achievement of GPs on tests measuring TK, DS, and TS was generally below 50%. This deficiency should be improved.

Changing Communities and Increases in the Prevalence of Depression: is there a Relationship? / Cambios en las comunidades y el aumento en la prevalencia de la depresión: ¿hay una relación?

The article analyses the impact of individualization processes on community-level determinants of health in postmodern societies, taking depression as an example. The analysis shows how the evolution of the broader social context towards forms of organization focused on the individual and on competition in a market economy implies the vanishing of traditional communities and there -fore of their health-supportive functions, thus endangering their ability to fulfill the needs of belonging, mutual support, and identity. The analysis also relates this evolution to cultural phenomena and to recent studies about culture -gene coevolution, implying that the effects of community decline are expected to be even greater in collectivist societies. Through its multidimensional conceptual analysis, this paper aims to contribute to further uncovering the interactions of psychological, psychosocial, and biological factors in mental health.

El artículo analiza el impacto que los procesos de individualización en las sociedades postmodernas tienen sobre los determinantes de salud de nivel comunitario, tomando como ejemplo la depresión. El análisis muestra cómo la evolución del contexto social más amplio hacia formas de organización enfocadas en el individuo y en la competencia de las economías de mercado, implican el desvanecimiento de las comunidades tradicionales y por lo tanto de sus funciones de apoyo a la salud. Es así que ponen en peligro su capacidad para satisfacer las necesidades de pertenencia, apoyo mutuo e identidad. El artículo también relaciona esta evolución con fenómenos culturales y con estudios recientes sobre la coevolución cultura-gen, implicando que los efectos de declinación de la comunidad deberían ser aún mayores en las sociedades colectivistas. A través de su análisis conceptual multidimensional, el artículo busca contribuir a profundizar sobre las interacciones de factores psicológicos, psicosociales y biológicos en salud mental.

[Qualitative impact of a training program on depressive disorders for primary care physicians]. / Impacto de una capacitación en trastornos depresivos para médicos generales de atención primaria en salud: resultados cualitativos.

BACKGROUND: There are suggestions that, despite training efforts for Primary Health Care physicians, difficulties in making accurate diagnoses and timely treatments persist. AIM: To evaluate the impact of a new training model in Depressive disorders integrated with Mindful Practice, on the diagnostic and therapeutic skills of primary care general physicians. MATERIAL AND METHODS: A voluntary sample of 56 general physicians was studied. The design of this study was experimental and randomized, with two groups attending theoretical sessions followed by differing workshops that were carried out in a parallel fashion. The Quantitative phase of this study considered measuring the impact of training in physician's skills. The Qualitative phase included nine semi-structured interviews and Qualitative Content Analysis. This paper reports the results of the interviews. RESULTS: As a consequence of training sessions, physicians learned that above the mental health problems, other issues such as self-efficacy and self-confidence are important for the management of depressive patients. CONCLUSIONS: This qualitative study shows that physicians are obtaining significant benefits from their training sessions.

Unconscious phantasy and its conceptualizations: An attempt at conceptual integration.

That there is a lack of consensus as to how to decide between competing, at times even contradictory theories, and about how to integrate divergent concepts and theories is well known. In view of this situation, the IPA Committee on Conceptual Integration (2009-2013) developed a method for comparing the different versions of any given concept, together with the underlying theories and fundamental assumptions on which they are based. Only when situated in the same frame of reference do similarities and differences begin to appear in a methodically comprehensible and reproducible form. After having studied the concept of enactment followed by the publication of a paper in this Journal in 2013, we proceeded to analyze the concept of unconscious phantasy while at the same time continuing to improve our method. Unconscious phantasy counts among the central concepts in psychoanalysis. We identified a wide range of definitions along with their various theoretical backgrounds. Our primary concern in the present paper addresses the dimensional analysis of the semantic space occupied by the various conceptualizations. By way of deconstructing the concepts we endeavoured to establish the extent to which the integration of the different conceptualizations of unconscious phantasy might be achieved.
