Opioid Overdose and Serotonin Syndrome due to Gastric Bezoar in a Woman with Autism and Pica Behaviour.

We are presenting the case of a 38-year-old woman with nonverbal autism and intellectual disability, hospitalized in a neurobehavioural unit because of a pica behaviour for 3 years. During the hospitalization, the patient presented an episode of pain, agitation, restlessness, rhabdomyolysis, coma, tachycardia, hyperthermia, shivering, and diarrhoea. The main hypothesis raised was tramadol overdose because of the immediate antidote response to the injection of naloxone 0,4 mg/mL.

Autism and COVID-19: A Case Series in a Neurodevelopmental Unit.

Background: COVID-19 has become pandemic and can impact individuals with autism as well. Here, we report a case series admitted to a neurobehavioral unit dedicated to challenging behaviors in patients with autism.

Methods: We describe 16 patients (mean age 20.

Developmental and symptom profiles in early-onset psychosis.

Psychotic disorders in children are more heterogeneous than is captured by categorical diagnoses. In a new cohort of children and adolescents, we evaluated the relationships among age at onset (AAO), clinical symptoms and developmental impairments. Patients with schizophrenia and other "spectrum" psychotic diagnoses (N = 88; AAO 6-17, mean 12.

Incidence of adverse events in antipsychotic-naïve children and adolescents treated with antipsychotic drugs: Results of a multicenter naturalistic study (ETAPE).

The main objective of ETAPE study was to determine the incidence of adverse events (AEs) potentially related to antipsychotic (AP) during a 12-months observational study of naturalistic treatment. ETAPE is a naturalistic prospective multicenter study conducted between April 2013 and May 2016. 200 patients were included.

Hormonal Risk Factors for Osteoporosis: Different Profile Among Antipsychotics.

Osteoporosis is a major risk factor for fracture and treatment is mainly preventive. Patients with severe psychiatric condition and treated with antipsychotics are at risk for vitamin D deficiency and iatrogenic hyperprolactinemia, two serious risk factors of osteoporosis. We aim to determine whether all antipsychotics are similar regarding the risk of osteoporosis in young patients.

Catatonia in Children and Adolescents: A High Rate of Genetic Conditions.

Pediatric catatonia is a rare and severe neuropsychiatric syndrome. We previously reported, in 58 children and adolescents with catatonia, a high prevalence (up to 20%) of medical conditions, some of which have specific treatments. Here we extend the cohort inclusion and report the first systematic molecular genetic data for this syndrome.

Disentangling Tourette syndrome heterogeneity through hierarchical ascendant clustering.

Aim: To explore the heterogeneity of Tourette syndrome as part of a neurodevelopmental spectrum.

Method: Using hierarchical ascendant clustering based on tic symptoms, developmental milestones, and neurodevelopmental comorbidities, we analyzed the heterogeneity of Tourette syndrome phenotypes in a sample of 174 children and adolescents with Tourette syndrome referred to a tertiary university clinic.

Results: The model yielded three distinct clusters characterized as follows.

Tourette syndrome and other neurodevelopmental disorders: a comprehensive review.

Gilles de la Tourette syndrome (TS) is a complex developmental neuropsychiatric condition in which motor manifestations are often accompanied by comorbid conditions that impact the patient's quality of life. In the DSM-5, TS belongs to the "neurodevelopmental disorders" group, together with other neurodevelopmental conditions, frequently co-occurring. In this study, we searched the PubMed database using a combination of keywords associating TS and all neurodevelopmental diagnoses.

An overview of medical risk factors for childhood psychosis: Implications for research and treatment.

Objective: Psychotic disorders in childhood and early adolescence often progress to chronic schizophrenia, but in many cases there are diagnosable medical and genetic causes or risk factors. We reviewed our clinical experience and the relevant literature to identify these factors and to define their clinical features, appropriate work-up and treatment.

Method: We reviewed the results of comprehensive medical evaluations of 160 psychotic children and adolescents in our center.

Incidence of adverse events in antipsychotic-naïve children and adolescents treated with antipsychotic drugs: a French multicentre naturalistic study protocol (ETAPE).

Introduction: In France, over recent years, the prescription rate of antipsychotic (AP) remained stable in children and adolescents. Prescription of second-generation antipsychotics increased, whereas prescription of first-generation antipsychotics decreased. Off-label prescriptions are very frequent in this population.

Facial, vocal and cross-modal emotion processing in early-onset schizophrenia spectrum disorders.

Recognition of emotional expressions plays an essential role in children's healthy development. Anomalies in these skills may result in empathy deficits, social interaction difficulties and premorbid emotional problems in children and adolescents with schizophrenia. Twenty-six subjects with early onset schizophrenia spectrum (EOSS) disorders and twenty-eight matched healthy controls (HC) were instructed to identify five basic emotions and a neutral expression.
