Changes in the clinical management of 5α-reductase type 2 and 17ß-hydroxysteroid dehydrogenase type 3 deficiencies in France.

Objectives: To examine the changes in diagnostic practices and clinical management of patients with 5α-reductase type 2 (SRD5A2) or 17ß-hydroxysteroid dehydrogenase type 3 (HSD17B3) deficiency since molecular diagnoses became available. Methods: Clinical, laboratory, and therapeutic data were retrieved from the medical records of 52 patients with a molecular diagnosis of SRD5A2 (n = 31) or HSD17B3 (n = 21) deficiency. Temporal trends regarding age at assessment and initial sex assignment over 1994-2020 were qualitatively analyzed. Age at molecular diagnosis was compared between two subgroups of patients according to their year of birth. Results: Fifty-eight percent (n = 30) patients were diagnosed during the perinatal period, 33% (n = 17) during infancy, and 9% (n = 5) during adolescence or adulthood. Over the studied period, the patients' age at initial assessment and diagnosis frankly decreased. The median (range) age at diagnostic confirmation was 10.5 (0-53.2) years for patients born before 2007 and 0.4 (0-9.3) years for those born in 2007 or later (P = 0.029). Genetic testing identified 27 different variants for the SRD5A2 gene (30% novel, n = 8) and 18 for the HSD17B3 gene (44% novel, n = 8). Before 2002, most patients were initially assigned as females (95%, n = 19), but this proportion dropped for those born later (44%, n = 14; P < 0.001). The influence of initial genital appearance on these decisions seemingly decreased in the most recent years. Therapeutic interventions differed according to the sex of rearing. Ten percent (n = 2) patients requested female-to-male reassignment during adulthood. Conclusion: This study showed, over the past two decades, a clear trend toward earlier diagnosis and assignment of affected newborns as males.

[Gender identity, between natural facts and constructed facts, an integrative and developmental approach]. / L'identité de genre, entre faits naturels et faits construits, une approche intégrative et développementale.

Title: L'identité de genre, entre faits naturels et faits construits, une approche intégrative et développementale. Abstract: À partir des années 1950, l'identité de genre, en ce qu'elle définit la conviction de l'individu d'appartenir à un genre ou à un autre, devient un objet de recherche médicale et scientifique. Partant des premiers travaux de John Money et de Robert Stoller, qui posent la possibilité d'une dimension polyfactorielle de la construction de l'identité de genre, les recherches les plus récentes portant sur les facteurs génétiques, neuroanatomiques, socio-cognitifs et psychodynamiques, réactualisent l'intérêt de pouvoir envisager un modèle polyfactoriel. Le paradigme clinique des variations du développement génital et des troubles du spectre de l'autisme entrouvre des hypothèses quant à l'articulation possible de ces facteurs de différentes natures. Pour appuyer tant ces éléments historiques que les données issues de la recherche actuelle, nous développerons en quoi les pratiques médicales actuelles vis-à-vis du genre s'inscrivent, sur le plan déontologique, dans une approche nécessairement individualisée soutenant un modèle polyfactoriel développemental.

Onset of psychiatric signs and impaired neurocognitive domains in inherited metabolic disorders: A case series.

Inherited metabolic disorders (IMDs) can present with psychiatric signs that vary widely from one disease to another. This picture is further complicated by the fact that these features occur at very different illness time points, which may further delay appropriate diagnosis and treatment. In this case series of 62 children and adolescents suffering from IMDs, we clustered psychiatric signs (on the basis of the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders classification) as well as impaired cognitive domains (on the basis of the Research Domain Criteriamatrix) according to their mean age of onset (5.7 ± 4 years). We observed consistent patterns of occurrence across disorders. Externalizing symptoms, sleep problems, and cross-domain self-regulation deficits were found to precede the IMD diagnosis. Repetitive thoughts and behaviors as well as emotional dysregulation were found to occur around the disease onset. Finally, late-onset features included dissociative or eating disorders, together with impaired emotion knowledge. Clinicians should specifically look for the co-occurrence of age-specific atypical signs, such as treatment resistance or worsening with psychotropic medication in the earliest stages and symptom fluctuation, confusion, catatonia, or isolated visual hallucinations. We believe that the combined characterizations of psychiatric signs and impaired neurocognitive domains may enable the earliest detection of IMDs and the appropriate care of these particular manifestations. KEY POINTS: Psychiatric signs are common in inherited metabolic disorders (IMDs) and may occur in the same age-range as other clinical manifestations.Three clusters of psychiatric signs and two clusters of neurocognitive domains can be defined according to their mean age of onset.Warning signs to be used in liaison psychiatry should include age-specific cognitive impairments.

Psychiatric autoimmune conditions in children and adolescents: Is catatonia a severity marker?

OBJECTIVES: Patients with autoimmune encephalitis (AE) are likely to exhibit an acute onset of severe psychiatric features, including psychosis and/or catatonia. Based on the high prevalence of catatonia in AE and our clinical experience, we hypothesized that catatonia might be a marker of severity requiring more aggressive treatment approaches. METHODS: To reach a sufficient number of cases with brain-autoimmune conditions, we pooled two samples (N = 58): the first from the French National Network of Rare Psychiatric diseases and the second from the largest Italian neuro-pediatrics center for encephalopathies. Autoimmune conditions were diagnosed using a multidisciplinary approach and numerous paraclinical investigations. We retrospectively compared patients with and without catatonia for psychiatric and non-psychiatric clinical features, biological and imaging assessments, type of immunotherapy used and outcomes. RESULTS: The sample included 25 patients (43%) with catatonia and 33 (57%) without catatonia. Forty-two patients (72.4%) had a definite AE (including 27 anti-NMDA receptor encephalitis) and 16 (27.6%) suspected autoimmune encephalitis. Patients with catatonia showed significantly more psychotic features [18 (72%) vs 9 (27.3%), p < 0.001)] and more movement disorders [25 (100%) vs 20 (60.6%), p < 0.001] than patients without catatonia. First line (corticoids, immunoglobulin and plasma exchanges) and second line (e.g., rituximab) therapies were more effective in patients with catatonia, with 24 (96%) vs 22 (66.7%) (p = 0.006) and 17 (68%) vs 9 (27.3%) (p = 0.002), respectively. However, those with catatonia received more combinations of first and second line treatments and had more relapses during outcomes. CONCLUSION: Despite its exploratory design, the study supports the idea that autoimmune catatonia may be a marker of severity and morbidity in terms of initial presentation and relapses, requiring the need for early and aggressive treatment.

Transgender fathering: Children's psychological and family outcomes.

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.

The Developmental Implications of the Use of Reproductive Technologies for Transgender People: A Comparative Cross-Section Protocol.

BACKGROUND: Today, individuals and couples with fertility issues can use advances in biomedical technologies to conceive. Transgender persons also benefit from these advances and can not only actualize their self-identified gender identities but also experience parenthood. These strategies for persons to self-actualize and to access parenthood have improved the condition of transgender persons. However, some may question the welfare of the offspring because such transfamily forms are often confusing to many. The sparse research on the psychological well-being of children of transgender people is reassuring. However, the limited empirical research justifies more studies to be conducted with an evidence-based methodology to assess whether these new methods of parenting have any adverse impact on children. AIMS: The current report details the protocol we built to compare cognitive development, mental health, gender identity, quality of life, and family dynamics in children of transgender fathers and donor sperm insemination (DSI) and two control groups matched for age and gende typically developing (TD) children and children from cisgender parents and DSI. HYPOTHESIS: To calculate sample sizes, we hypothesize no significant difference between groups. SUBJECTS AND METHODS: Since 2008, married couples that include a transgender father have been able to access DSI and have started conceiving children in France. They are always invited to participate in research to assess their children's well-being. To date, the cohort includes 53 children in 37 families. We propose to carry out a cross-sectional comparative study exploring cognitive development with the Brunet-Lézine Psychomotor Development Scale or Wechsler's Intelligence Scales according to age; mental health with the Child Behaviour Checklist; gender identity with the Gender Identity Interview for Children; quality of life with the KIDSCREEN and the Adolescent Coping Questionnaire; and family dynamics with the Parental Bonding Instrument, the Inventory of Parent and Peer Attachment, the Five-Minute Speech Sample, and Corman's Family Drawing Test. To assess possible subtle differences between children's family drawings, we will use a generalization of the "lady-tasting-tea" procedure to link qualitative and quantitative approaches in psychiatric research. Twenty raters [four child and family psychoanalysts (CHILDPSY), four adult psychiatrists (ADUPSY), four biologists working in assistive reproduction technology (BIOL), four endocrinologists working with transgender individuals (ENDOC), and four students (STUD)] will be randomly shown the drawings and asked to blindly classify them using a Likert scale according to whether the child has a transgender father. STATISTICAL ANALYSIS: After testing normality, comparisons between the three groups will be performed with appropriate statistical tests (Kruskal-Wallis, ANOVA, Chi2 or Fisher's exact test). For the "lady-tasting-tea" procedure, we will use a permutation test. ETHICS: The study protocol has been approved by the CERES (Comité d'Ethique de Recherche en Santé) of Paris 5 University. Registration number is 2015/31.

Deviations in early hippocampus development contribute to visual hallucinations in schizophrenia.

Auditory hallucinations (AHs) are certainly the most emblematic experiences in schizophrenia, but visual hallucinations (VHs) are also commonly observed in this developmental psychiatric disorder. Notably, several studies have suggested a possible relationship between the clinical variability in hallucinations' phenomenology and differences in brain development/maturation. In schizophrenia, impairments of the hippocampus, a medial temporal structure involved in mnesic and neuroplastic processes, have been repeatedly associated with hallucinations, particularly in the visual modality. However, the possible neurodevelopmental origin of hippocampal impairments in VHs has never been directly investigated. A classic marker of early atypical hippocampal development is incomplete hippocampal inversion (IHI). In this study, we compared IHI patterns in healthy volunteers, and two subgroups of carefully selected schizophrenia patients experiencing frequent hallucinations: (a) those with pure AHs and (b) those with audio-visual hallucinations (A+VH). We found that VHs were associated with a specific IHI pattern. Schizophrenia patients with A+VH exhibited flatter left hippocampi than patients with pure AHs or healthy controls. This result first confirms that the greater clinical impairment observed in A+VH patients may relate to an increased neurodevelopmental weight in this subpopulation. More importantly, these findings bring crucial hints to better specify the sensitivity period of A+VH-related IHI during early brain development.

Association between childhood trauma and multimodal early-onset hallucinations.

Previous reports suggest that adverse events during childhood could be related to an array of psychiatric problems. Here, we question the relationship between childhood traumatic experiences and the sensory complexity of hallucinations in a cohort of 75 children and adolescents. We evidence a positive link between the number of sensory modalities involved in hallucinations and history of childhood trauma, even after controlling for the co-occurrence of suicidal ideation or the number of ICD-10 diagnoses. These findings support initiatives in which a routine exploration of traumatic events in childhood is performed when multimodal hallucinations are present.

Construction and Validation of an Analytical Grid about Video Representations of Suicide ("MoVIES").

Background. Exposure to fictional suicide scenes raises concerns about the risk of suicide contagion. However, researchers and clinicians still lack empirical evidence to estimate this risk. Here, we propose a theory-grounded tool that measures properties related to aberrant identification and suicidal contagion of potentially harmful suicide scenes. Methods. The items of the Movies and Video: Identification and Emotions in reaction to Suicide (MoVIES) operationalize the World Health Organization's recommendations for media coverage of suicide, and were adapted and completed with identification theory principles and cinematographic evidence. Inter-rater reliability (Cohen's kappa) and internal consistency (Cronbach's alpha) were estimated and optimized for two series of 19 and 30 randomly selected movies depicting a suicide scene. The validity of the scale in predicting identification with the suicidal character was tested in nine unknowledgeable participants who watched seven suicide movie scenes each. Results. The MoVIES indicated satisfying psychometric properties with kappas measured at 0.7 or more for every item and a global internal consistency of [α = 0.05]. The MoVIES score significantly predicted participants' strength of identification independently from their baseline empathy ((ß = 0.20), p < 0.05). Conclusions. The MoVIES is available to scholars as a valid, reliable, and useful tool to estimate the amount of at-risk components of fictional suicidal behavior depicted in films, series, or television shows.

Catatonia Associated With a SCN2A-Related Disorder in a 4-Year-Old Child.

Catatonia is a rare, underdiagnosed syndrome in children. We report the case of a 4-year-old child admitted for recent social withdrawal alternating with psychomotor excitement, verbigeration, and a loss of toilet readiness. He had a history of neonatal seizures, had been stabilized with vigabatrin, and was seizure free without treatment for several months. The pediatric and psychiatric examination revealed motor stereotypes, mannerism, bilateral mydriasis, and visual hallucinations. Laboratory and brain imaging explorations were initially negative. Catatonic symptoms, as measured with the Pediatric Catatonia Rating Scale, significantly decreased after introducing lorazepam, the first-line recommended treatment of this condition. On the basis of the neonatal seizure history, complementary genetic investigations were performed and revealed a mutation in the SCN2A gene, which encodes the voltage-gated sodium channel Nav1.2. Catatonic symptoms progressively disappeared after reintroducing vigabatrin. At the syndromic level, catatonia in young children appears responsive to high-dose lorazepam and is well monitored by using the Pediatric Catatonia Rating Scale. This case reveals the need for wide-ranging explorations in early-onset catatonia because specific targeted treatments might be available.

Therapeutic body wraps (TBW) for treatment of severe injurious behaviour in children with autism spectrum disorder (ASD): A 3-month randomized controlled feasibility study.

INTRODUCTION: The use of therapeutic body wraps (TBW) has been reported in small series or case reports, but has become controversial. OBJECTIVES: This is a feasibility, multicentre, randomized, controlled, open-label trial with blinded outcome assessment (PROBE design). SETTING: Children with autism and severe-injurious behaviours (SIB) were enrolled from 13 specialized clinics. INTERVENTIONS: Dry-sheet TBW (DRY group) vs. wet-sheet TBW (WET group). PRIMARY OUTCOME MEASURES: 3-month change in the Aberrant Behaviour Checklist irritability score (ABC-irritability) within per-protocol (PP) sample. RESULTS: From January 2008 to January 2015, we recruited 48 children (age range: 5.9 to 9.9 years, 78.1% male). Seven patients (4 in the DRY group, 3 in the WET group) were dropped from the study early and were excluded from PP analysis. At endpoint, ABC-irritability significantly improved in both groups (means (standard deviation) = -11.15 (8.05) in the DRY group and -10.57 (9.29) in the WET group), as did the other ABC scores and the Children Autism Rating scale score. However, there was no significant difference between groups. All but 5 patients were rated as much or very much improved. A repeated-measures analysis confirmed the significant improvement in ABC-irritability scores according to time (p < .0001), with no significant difference between the two groups (group effect: p = .55; interaction time x group: p = .27). Pooling both groups together, the mean 3-month change from baseline in ABC-irritability score was -10.90 (effect size = 1.59, p < .0001). CONCLUSIONS: We found that feasibility was overall satisfactory with a slow recruitment rate and a rather good attrition rate. TBW was a safe complementary therapy in this population. There was no difference between wet and dry TBW at 3 months, and ABC-irritability significantly decreased with both wet and dry sheet TBW. To assess whether TBW may constitute an alternative to medication or behavioural intervention for treating SIB in ASD patients, a larger randomized comparative trial (e.g. TBW vs. antipsychotics) is warranted. TRIAL REGISTRATION: ClinicalTrials.gov NCT03164746.

Very early hallucinatory experiences: a school-based study.

BACKGROUND: The prevalence and clinical significance of hallucinatory experiences among children below 7 years of age remain unknown. We aimed to determine the independent influences of sensory deficits, the presence of an imaginary companion and metacognition on hallucinatory experiences. We assumed that hallucinatory experiences were associated with (a) sensory deficits, (b) the presence of an imaginary companion (IC) and (c) metacognition defaults (i.e. first- and second-order theory of mind default). METHODS: All children in the third year of preschool from a region of Northern France underwent medical screening. We compared the prevalence rates of visual, auditory and audio-visual hallucinatory experiences based on (a) the presence of visual or auditory deficits, (b) the actual presence of an IC and (c) metacognition. The analyses were adjusted for age. RESULTS: A total of 1,087 children aged between 5 and 7 years were included. The prevalence rates of auditory, visual and audio-visual hallucinatory experiences were 15.8%, 12.5% and 5.8%, respectively. The prevalences of different types of hallucinatory experiences were not significantly different according to sensory deficit. The prevalences of all types of hallucinatory experiences were significantly higher among children with an IC and among children with metacognition defaults. CONCLUSIONS: The association between hallucinatory experiences and sensory deficits might concern only long-lasting deficits. The association with the presence of an IC confirms experimental findings of the likelihood of perceiving words among meaningless auditory stimuli. Relations between hallucinatory experiences and theory of mind need to be addressed in longitudinal studies.

[Mental illness and pregnancy]. / Pathologie psychiatrique et grossesse.

Pregnancy was once thought a period of bliss devoid of mental illness. We now know this is not so. It is well documented that pregnancy and the peripartum are not only a time when preexisting mental illness will persist but that it is also a high-risk period for renewed episodes of mental illness, whether de novo or relapse. In this paper, we will describe the three main axis of management of maternal mental illness during the peripartum: maternal psychiatric illness, fetal, neonatal and infant development and future mother-infant relationship. We will give an overview of how to organize care for mothers with schizophrenia and bipolar disorder. Good practice management of psychotropic medication during this period will be described. Finally the importance of networking and multidisciplinary management of these situations will be underlined.
