RESUMO

More than 10% of births are preterm, and the long-term consequences on sensory and semantic processing of non-linguistic information remain poorly understood. 17 very preterm-born children (born at < 33 weeks gestational age) and 15 full-term controls were tested at 10 years old with an auditory object recognition task, while 64-channel auditory evoked potentials (AEPs) were recorded. Sounds consisted of living (animal and human vocalizations) and manmade objects (e.g. household objects, instruments, and tools). Despite similar recognition behavior, AEPs strikingly differed between full-term and preterm children. Starting at 50ms post-stimulus onset, AEPs from preterm children differed topographically from their full-term counterparts. Over the 108-224ms post-stimulus period, full-term children showed stronger AEPs in response to living objects, whereas preterm born children showed the reverse pattern; i.e. stronger AEPs in response to manmade objects. Differential brain activity between semantic categories could reliably classify children according to their preterm status. Moreover, this opposing pattern of differential responses to semantic categories of sounds was also observed in source estimations within a network of occipital, temporal and frontal regions. This study highlights how early life experience in terms of preterm birth shapes sensory and object processing later on in life.

RESUMO

The aim of this study was to examine associations between maternal mentalization, interactive behavior, and child symptoms in families in which mothers suffer from interpersonal violence-related posttraumatic stress disorder (IPV-PTSD). Fifty-six mothers and children (aged 12-42 months) including mothers with a diagnosis of IPV-PTSD were studied. Mentalization was measured by the Parental Reflective Functioning (PRF) Scale. Interactive behavior during free-play was measured via the CARE-Index. Child symptoms were measured by the Infant-Toddler Social and Emotional Assessment (ITSEA). Data analyses included non-parametric correlations and multiple linear regression. Results showed that lower IPV-PTSD and higher Maternal Reflective Functioning (MRF) were related to greater maternal sensitivity. Lower MRF and greater controlling behavior were related to child dysregulation. MRF was found to be lower in the subgroup of IPV-PTSD when the child's father was the perpetrator of IPV. Both MRF and interactive behavior are thus likely to be important targets for intervention during sensitive periods of early social-emotional development.

RESUMO

OBJECTIVE: To investigate the evolution of maternal representations (ie, the way parents perceive their child in term of temperament, character, behaviors, etc) of children with a cleft at 3 major milestones: before/after reconstructive surgeries and at school age. Parenting style was also analyzed and compared with parents of children born without a cleft. DESIGN AND PARTICIPANTS: The sample was composed of 30 mothers of children with an orofacial cleft and 14 mothers of children without a cleft. Maternal representations were assessed when the child was 2 months (before surgery), 12 months (after surgery), and 5 years of age (when starting school) using semistructured interviews that were transcribed and coded according to the subscales of the Working Model of the Child Interview and the Parental Development Interview. At the 5-year appointment, mothers also completed a questionnaire about parenting style. RESULTS: Results showed no difference across groups (cleft/noncleft) in maternal representations at the 2-month, 12-month, and 5-year assessments. In the cleft group, significant differences were shown between 2 and 12 months in caregiving sensitivity, perceived infant difficulty, fear for the infant's safety, and parental pride, all factors being higher at 12 months. Those differences in parental representations over time were not found in the noncleft group. Additionally, mothers of the cleft group were significantly more authoritarian than mothers of children without a cleft. CONCLUSION: The absence of differences across cleft and noncleft groups suggests that having a child with a cleft does not affect maternal representations and emotions between 2 months and 5 years of the child's age. However, parenting style seems to be influenced by the presence of a cleft in the present sample.

RESUMO

This study examines the attachment quality and how this changed over time among infants who had cleft lip and palate (CLP), by conducting a prospective longitudinal study addressing the effects of this type of perinatal event on the parent-infant relationship and the emotional development of the infants. At 12 months of age, the Strange Situation Paradigm (SSP; M. Ainsworth, M.C. Blehar, E. Waters, & T. Wall, 1978) was administered to a sample of 38 CLP infants (born between 2003 and 2010) and 17 healthy controls. At 4 years of age, the Attachment Story Completion Task (ASCT; I. Bretherton, D. Ridgeway, & J. Cassidy, 1990) was administered to 32 individuals from the CLP sample and 14 from the control group. As reported in the literature, CLP infants display secure attachment behaviors as frequently as do control infants (55%). However, a more detailed analysis of the attachment scales revealed that CLP infants show more avoidance and less proximity seeking. In addition, a closer examination of the subcategories of attachment styles revealed that most CLP infants (71%) displayed distal attachment strategies such as the B1/B2 or A1/A2 subcategories. At 4 years old, CLP infants clearly displayed more deactivation and less security than did the control sample. Moreover, when detailing the evolution of attachment individually, almost 60% of the CLP children showing distal strategies at 12 months became deactivated or disorganized when they reached 4 years. Indeed, subtle differences in attachment behaviors at 12 months old-which can be considered marginally secure at that age-may reveal attachment vulnerabilities, which seem to be more apparent over the course of development.

RESUMO

Women who have experienced interpersonal violence (IPV) are at a higher risk to develop posttraumatic stress disorder (PTSD), with dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and impaired social behavior. Previously, we had reported impaired maternal sensitivity and increased difficulty in identifying emotions (i.e. alexithymia) among IPV-PTSD mothers. One of the aims of the present study was to examine maternal IPV-PTSD salivary cortisol levels diurnally and reactive to their child's distress in relation to maternal alexithymia. Given that mother-child interaction during infancy and early childhood has important long-term consequences on the stress response system, toddlers' cortisol levels were assessed during the day and in response to a laboratory stressor. Mothers collected their own and their 12-48month-old toddlers' salivary samples at home three times: 30min after waking up, between 2-3pm and at bedtime. Moreover, mother-child dyads participated in a 120-min laboratory session, consisting of 3 phases: baseline, stress situation (involving mother-child separation and exposure to novelty) and a 60-min regulation phase. Compared to non-PTSD controls, IPV-PTSD mothers - but not their toddlers, had lower morning cortisol and higher bedtime cortisol levels. As expected, IPV-PTSD mothers and their children showed blunted cortisol reactivity to the laboratory stressor. Maternal cortisol levels were negatively correlated to difficulty in identifying emotions. Our data highlights PTSD-IPV-related alterations in the HPA system and its relevance to maternal behavior. Toddlers of IPV-PTSD mothers also showed an altered pattern of cortisol reactivity to stress that potentially may predispose them to later psychological disorders.

RESUMO

The medical, psychological and social aspects of disorders of sex development (DSD) represent a challenge for the management of these patients. However, advances in our understanding of the etiology and genetics of this condition, novel surgical approaches and the growing influence of patient groups as well as wider recognition of ethical issues have helped improve the care of patients with a DSD. Importantly, a multidisciplinary approach involving specialists is crucial for understanding and treating such rare and complex cases. According to the recommendations of the Swiss National Ethical Commission, we shall use the term « Variation of Sex Development ¼ rather than « Disorder of Sex Development ¼ in this publication. This article addresses the care of DSD patients throughout development from the point of view of specialists in complementary fields.


La prise en charge des personnes avec une variation du développement sexuel (VDS) (disorder of sex development, DSD) est un défi tant sur le plan médical, psychologique que social. L'amélioration des connaissances étiologiques et génétiques, les nouvelles approches chirurgicales et l'influence tant des groupes de patients que de la Commission d'éthique suisse ont considérablement modifié la vision de la prise en charge de ces personnes durant ces dernières décennies. Une approche pluridisciplinaire et spécialisée est cruciale pour appréhender ces situations rares et souvent complexes. Le point de vue des différents spécialistes impliqués au long de la vie dans la prise en charge d'une VDS est abordé dans cet article.

RESUMO

Preterm infants experience intense stress during the perinatal period because they endure painful and intense medical procedures. Repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis during this period may have long-term effects on subsequent cortisol regulation. A premature delivery may also be intensely stressful for the parents, and they may develop symptoms of posttraumatic stress disorder (PTSD). Usable saliva samples were collected (4 times per day over 2 days, in the morning at awakening, at midday, in the afternoon, and in the evening before going to bed) to assess the diurnal cortisol regulation from 46 preterm infants when the infants were 12 months of corrected age (∼ 14 months after birth). Mothers reported their level of PTSD symptoms. The results showed an interaction between perinatal stress and maternal traumatic stress on the diurnal cortisol slope of preterm infants (R(2) = .32). This suggests that the HPA axis of preterm infants exposed to high perinatal stress may be more sensitive to subsequent environmental stress.

RESUMO

Objective : The main objective of this study was to assess mother-child patterns of interaction in relation to later quality of attachment in a group of children with an orofacial cleft compared with children without cleft. Design : Families were contacted when the child was 2 months old for a direct assessment of mother-child interaction and then at 12 months for a direct assessment of the child's attachment. Data concerning socioeconomical information and posttraumatic stress symptoms in mothers were collected at the first appointment. Participants : Forty families of children with a cleft and 45 families of children without cleft were included in the study. Families were recruited at birth in the University Hospital of Lausanne. Results : Results showed that children with a cleft were more difficult and less cooperative during interaction at 2 months of age with their mother compared with children without a cleft. No significant differences were found in mothers or in dyadic interactive styles. Concerning the child's attachment at 12 months old, no differences were found in attachment security. However, secure children with a cleft were significantly more avoidant with their mother during the reunion episodes than secure children without cleft. Conclusion : Despite the facial disfigurement and the stress engendered by treatment during the first months of the infant's life, children with cleft and their mothers are doing as well as families without cleft with regard to the mothers' mental health, mother-child relationships, and later quality of attachment. A potential contribution for this absence of difference may be the pluridisciplinary support that families of children with cleft benefit from in Lausanne.

RESUMO

BACKGROUND: Although long-term implications of cancer in childhood or adolescence with regard to medical conditions are well documented, the impact on mental health and on response to stress, which may be an indicator of psychological vulnerability, is not yet well understood. In this study, psychological and physiological responses to stress were examined. PROCEDURE: Fifty-three participants aged 18-39 years (n = 25 survivors of childhood or adolescence cancer, n = 28 controls) underwent an experimental stress test, the Trier Social Stress Test (TSST). Participants were asked to provide repeated evaluations of perceived stress on visual-analogical scales and blood samples were collected before and after the TSST to measure plasma cortisol. RESULTS: The psychological perception of stress was not different between the two groups. However, the cancer survivors group showed a higher global plasma cortisol level as well as higher amplitude in the response to the TSST. The global cortisol level in cancer survivors was increased when depression symptoms were present. The subjective perception of stress and the plasma cortisol levels were only marginally correlated in both groups. CONCLUSIONS: It is suggested that the exposure to a life-threatening experience in childhood/adolescence increases the endocrine response to stress, and that the presence of depressive symptoms is associated with an elevation of plasma cortisol levels. A better knowledge of these mechanisms is important given that the dysregulations of the stress responses may cause psychological vulnerability.

RESUMO

There are many factors contributing to individual variations in the response to stressful experiences. The present study evaluated the patterns of stress responses according to attachment representations in 28 adults from a community sample, plus 46 subjects expected to be particularly sensitive to stress, having been exposed during childhood and/or adolescence to traumatizing events such as abuse or potentially lethal illnesses. Subjects were given the Adult Attachment Interview, which provides attachment classifications, and the Trier Social Stress Test (TSST), involving an experimental psychosocial challenge. Subjective responses to the TSST, as well as saliva samples (assayed for cortisol) and blood plasma samples (assayed for ACTH and oxytocin) were collected before, during and after the stress procedure. The stress responses presented specific patterns according to attachment classifications. Subjects with an autonomous attachment classification reported relatively low subjective stress, they presented a moderate response of the hypothalamic-pituitary-adrenal (HPA) axis (ACTH and cortisol), and a high level of oxytocin. Subjects with a dismissing classification reported a moderate subjective stress, they presented an elevated response of the HPA axis, and moderate levels of oxytocin. Subjects with a preoccupied classification presented moderate levels of subjective stress, and of HPA response, and a relatively low level of oxytocin. Finally, subjects with an unresolved classification reported elevated subjective stress; they presented a suppressed HPA response, and moderate levels of oxytocin. These data support the notion that attachment representations may affect stress responses, and suggest a specific role of oxytocin in both the attachment system and the stress system.

RESUMO

Through research into the molecular and cellular mechanisms that occur during critical periods, recent experimental neurobiological data have brought to light the importance of early childhood. These have demonstrated that childhood and early environmental stimuli play a part not only in our subjective construction, but also in brain development; thus, confirming Freud's intuition regarding the central role of childhood and early experiences of the environment in our psychological development and our subjective outcomes. "Critical periods" of cerebral development represent temporal windows that mark favorable, but also circumscribed, moments in developmental cerebral plasticity. They also vary between different cortical areas. There are, therefore, strictly defined temporal periods for learning language, music, etc., after which this learning becomes more difficult, or even impossible, to acquire. Now, research into these critical periods can be seen as having a significant part to play in the interdisciplinary dialog between psychoanalysis and neurosciences with regard to the role of early experiences in the etiology of some psychopathological conditions. Research into the cellular and molecular mechanisms controlling the onset and end of these critical periods, notably controlled by the maturation of parvalbumin-expressing basket cells, have brought to light the presence of anomalies in the maturation of these neurons in patients with schizophrenia. Starting from these findings we propose revisiting the psychoanalytic theories on the etiology of psychosis from an interdisciplinary perspective. Our study works from the observation, common to both psychoanalysis and neurosciences, that experience leaves a trace; be it a "psychic" or a "synaptic" trace. Thus, we develop a hypothesis for an "absence of trace" in psychosis; reexamining psychosis through the prism of the biological theory of critical periods in plasticity.

RESUMO

The economic conceptualization of Freudian metapsychology, based on an energetics model of the psyche's workings, offers remarkable commonalities with some recent discoveries in neuroscience, notably in the field of neuroenergetics. The pattern of cerebral activity at resting state and the identification of a default mode network (DMN), a network of areas whose activity is detectable at baseline conditions by neuroimaging techniques, offers a promising field of research in the dialogue between psychoanalysis and neuroscience. In this article we study one significant clinical application of this interdisciplinary dialogue by looking at the role of the DMN in the psychopathology of schizophrenia. Anomalies in the functioning of the DMN have been observed in schizophrenia. Studies have evidenced the existence of hyperactivity in this network in schizophrenia patients, particularly among those for whom a positive symptomatology is dominant. These data are particularly interesting when considered from the perspective of the psychoanalytic understanding of the positive symptoms of psychosis, most notably the Freudian hypothesis of delusions as an "attempt at recovery." Combining the data from research in neuroimaging of schizophrenia patients with the Freudian hypothesis, we propose considering the hyperactivity of the DMN as a consequence of a process of massive reassociation of traces occurring in schizophrenia. This is a process that may constitute an attempt at minimizing the excess of free energy present in psychosis. Modern models of active inference and the free energy principle (FEP) may shed some light on these processes.

RESUMO

OBJECTIVE: The announcement, prenatally or at birth, of a cleft lip and/or palate represents a challenge for the parents. The purpose of this study is to identify parental working internal models of the child (parental representations of the child and relationship in the context of attachment theory) and posttraumatic stress disorder symptoms in mothers of infants born with a cleft. METHOD: The study compares mothers with a child born with a cleft (n  =  22) and mothers with a healthy infant (n  =  36). RESULTS: The study shows that mothers of infants with a cleft more often experience insecure parental working internal models of the child and more posttraumatic stress symptoms than mothers of the control group. It is interesting that the severity or complexity of the cleft is not related to parental representations and posttraumatic stress disorder symptoms. The maternal emotional involvement, as expressed in maternal attachment representations, is higher in mothers of children with a cleft who had especially high posttraumatic stress disorder symptoms, as compared with mothers of children with a cleft having fewer posttraumatic stress disorder symptoms. DISCUSSION: Mothers of children with a cleft may benefit from supportive therapy regarding parent-child attachment, even when they express low posttraumatic stress disorder symptoms.

RESUMO

Thirty-three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow-up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991). At 4 months, mother-infant play interaction was observed and coded according to the CARE-index (P.M. Crittenden, 2003); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long-term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants.

RESUMO

The existence of disturbances in the perception of somatic states and in the representation of the body with the presence of cœnesthetic hallucinations, of delusional hypochondriac ideas or of dysmorphophobias is a recognized fact in the psychopathology of schizophrenia. Freudian psychoanalytic theory had accorded a privileged place to the alteration of the perception of the body in schizophrenia. Freud had attributed to these phenomena a primary and prodromal role in the psychopathology of psychosis. We propose to look at this theory in a new way, starting from the perspective of recent studies about the role of the insula in the perception and representation of somatic states, since this structure has been identified as underpinning the sense of interoception. The data in the neurobiological literature about abnormalities in the insular cortex in schizophrenia has shown that insula dysfunction could constitute one of the biological substrates of disorders of body perception in schizophrenia, and could be a source of the alteration of the sense of self that is characteristic of this psychiatric pathology. Moreover, this alteration could thus be involved in the positive symptomatology of schizophrenia.

RESUMO

We report the case of a 34-year-old female resulting from a father-daughter sexual abuse and presenting a phenotype of mild intellectual disability with minor dysmorphic features. Karyotyping showed a normal 46, XX constitution. Array-based comparative genomic hybridization (array-CGH) revealed a heterozygote 320kb 6p22.3 microdeletion in the proband, encompassing only one known gene, and therefore unlikely to be the cause of the phenotype. However, the role of other genetic factors, such as a recessive condition, could not be ruled out as a putative cause for the phenotype. On the other hand, the role played by a heavily detrimental familial situation on the development and outcome, and possibly leading or contributing to a mild intellectual disability, should be taken into account.

RESUMO

In the Freudian theory of the psychical apparatus, the introduction from the 1920s onward of the second drive dualism appears as a major turning point. The idea of a "death drive," first expressed in Beyond the Pleasure Principle (Freud, 1920), is generally considered to be a new concept, one that represents a break with Freud's previous thinking. It has often surprised the scholars because it seemed, at first sight, difficult to reconcile with the idea of the singularity of living organisms within which the psychical functions form an integral part. Our research aims to demonstrate that the theory of the death drive does not represent a complete change in direction for Freud. It is present, in essence, in his earliest work, to the extent that the "principle of inertia" described in 1895 in A Project for a Scientific Psychology (Freud, 1895) can be seen as a precursor to the death drive. Based on a reading of Freud's early formulations of his ideas, we aim to bring to light how certain aporias that seem inherent to the concept of the death drive can be overcome if we consider them in the context of an epistemological model that draws on the paradigms of physics which were conveyed by the Helmholtz School. Namely, we can consider the idea of death drive in reference to the principle of entropy and the laws of thermodynamics.

RESUMO

Medical advances in assisted reproductive technology have created new ways for transgender persons to become parents outside the context of adoption. The limited empirical data does not support the idea that trans-parenthood negatively impacts children's development. However, the question has led to lively societal debates making the need for evidence-based studies urgent. We aimed to compare cognitive development, mental health, gender identity, quality of life and family dynamics using standardized instruments and experimental protocols in 32 children who were conceived by donor sperm insemination (DSI) in French couples with a cisgender woman and a transgender man, the transition occurring before conception. We constituted two control groups matched for age, gender and family status. We found no significant difference between groups regarding cognitive development, mental health, and gender identity, meaning that neither the transgender fatherhood nor the use of DSI had any impact on these characteristics. The results of the descriptive analysis showed positive psycho-emotional development. Additionally, when we asked raters to differentiate the family drawings of the group of children of trans-fathers from those who were naturally conceived, no rater was able to differentiate the groups above chance levels, meaning that what children expressed through family drawing did not indicate cues related to trans-fatherhood. However, when we assessed mothers and fathers with the Five-Minute Speech Sample, we found that the emotions expressed by transgender fathers were higher than those of cisgender fathers who conceived by sex or by DSI. We conclude that the first empirical data regarding child development in the context of trans-parenthood are reassuring. We believe that this research will also improve transgender couple care and that of their children in a society where access to care remains difficult in this population. However, further research is needed with adolescents and young adults.
