The Organization of Diagnosis, Care and Funding for Specific Learning and Developmental Disorders (SLDD): A French Regional Experimental Protocol.

Access in France to early diagnosis and care for the most severe, but infrequent, Neurodevelopmental Disorders (NDD), autism spectrum disorder and global developmental delay, in children aged 0-7 was improved through measures implemented in 2019. However, there are no such measures for specific learning disorders (SLD), attention, motricity and language disorders (SLDD), despite their annual incidence of between 5 and 8%. We describe the design of a new type of organization and financing of care for SLDD including evaluation procedure, as well as other factors, mainly at the prevention level that will contribute to local and national policy for this frequent health problem.

Introduction: Despite a similar health insurance coverage and access to contraception, Martinique F.W.I.

Topiramate in childhood epileptic encephalopathy with continuous spike-waves during sleep: A retrospective study of 21 cases.

Objective: Encephalopathy with continuous spike-wave during sleep (CSWS) is a particularly difficult-to-treat childhood epileptic syndrome. This study sought to present the EEG improvement and clinical efficacy of topiramate (TPM), a broad spectrum antiepileptic drug (AED), in a series of 21 children with CSWS encephalopathy.

Methods: We retrospectively reviewed the EEG results and clinical data of children with CSWS followed-up in our institution and treated with TPM.

Ring Opening Reactions through C-O Bond Cleavage Uniquely Adding Chemical Functionality to Boron Subphthalocyanine.

We are reporting the unexpected reaction between bromo-boron subphthalocyanine (Br-BsubPc) and THF, 1,4-dioxane or γ-butyrolactone that results in the ring opening of the solvent and its addition into the BsubPc moiety. Under heating, the endocyclic C-O bond of the solvent is cleaved and the corresponding bromoalkoxy-BsubPc derivative is obtained. These novel alkoxy-BsubPc derivatives have remaining alkyl-bromides suitable for further functionalization.

The effect of donor-modification in organic light-harvesting motifs: triphenylamine donors appended with polymerisable thienyl subunits.

A family of seven organic triphenylamine-based dyes suitable for dye-sensitized solar cell (DSSC) applications is reported. The donor portion of these dyes has been systematically modified using polymerisable thienyl subunits. The physicochemical properties and device performance are discussed with device efficiencies ranging from 5.

Manipulating non-innocent π-spacers: the challenges of using 2,6-disubstituted BODIPY cores within donor-acceptor light-harvesting motifs.

The syntheses and physicochemical properties for a series of 2,6-disubstituted-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dyes are reported. The use of chromophores or redox active species as π-spacers, such as BODIPY, requires the inclusion of a sufficiently conjugated donor in order to achieve appropriate charge separation upon photoexcitation. The information derived from this study offers guiding principles for incorporating strongly absorbing, non-innocent π-spacers in organic dye design.

Language impairment associated with arachnoid cysts: recovery after surgical treatment.

Supporting data from the literature, we observe that large arachnoid cysts may affect cognitive function. Neuropsychologic assessment plus magnetic resonance imaging allowed for documentation of associations between left temporal arachnoid cysts, language impairment, and other cognitive dysfunctions. Significant cognitive improvements were evident soon after cysto-peritoneal shunting.

Early bifrontal brain injury: disturbances in cognitive function development.

We describe six psychomotor, language, and neuropsychological sequential developmental evaluations in a boy who sustained a severe bifrontal traumatic brain injury (TBI) at 19 months of age. Visuospatial, drawing, and writing skills failed to develop normally. Gradually increasing difficulties were noted in language leading to reading and spontaneous speech difficulties.

Borenium cations derived from BODIPY dyes.

Fluoride abstraction from a BODIPY dye gives a well defined borenium ion which can be converted to a borenium hydride via treatment with DIBAL-H.

Evaluation of early stimulation programs for enhancing brain development.

Unlabelled: The term 'early intervention' designates educational and neuroprotection strategies aimed at enhancing brain development. Early educational strategies seek to take advantage of cerebral plasticity. Neuroprotection, a term initially used to characterize substances capable of preventing cell death, now encompasses all interventions that promote normal development and prevent disabilities, including organisational, therapeutic and environment-modifying measures, such as early stimulation programs.

[<< Early stimulation >> programs evaluation].

Early intervention include educational and neuroprotection strategies. Early educational strategies are based on the cerebral plasticity concept. Neuroprotection, initially reserved for molecules preventing cell death phenomena, can be extended now to all actions promoting harmonious development and preventing handicaps, and include organisational, therapeutic and environmental aspects.

Neurodevelopmental outcome after severe traumatic brain injury in very young children: role for subcortical lesions.

Traumatic brain injury is a major cause of mortality and morbidity in children younger than 15 years of age. To evaluate the role of subcortical lesions on neurodevelopmental outcomes, long-term outcomes of 50 children with severe traumatic brain injury before 4 years of age (accidental injury, n = 21, nonaccidental injury, n = 29) were reviewed retrospectively and compared with late magnetic resonance imaging (MRI) findings: no visible lesions, cortical lesions, or subcortical lesions. Subcortical lesions occurred in both accidental and nonaccidental traumatic brain injuries.

The association between developmental handicaps and traumatic brain injury during pregnancy: an issue that deserves more systematic evaluation.

Aims: Trauma during pregnancy is commonly viewed as benign for the foetus when the delivery occurs normally. This study revisits that point of view.

Method: We included eighteen patients having a neurological handicap with an anamnesis of an accident during pregnancy and a follow-up sufficient to determine a definite outcome.

Levetiracetam in a neonate with malignant migrating partial seizures.

This report describes the first neonatal case of "malignant migrating partial seizures in infancy" with a positive therapeutic response to levetiracetam. This patient is the youngest reported infant with this rare syndrome, and the report provides the first documentation on levetiracetam treatment in a neonatal patient. Treatment with levetiracetam improved both ictal and interictal status.

Use of segmented CT transmission map to avoid metal artifacts in PET images by a PET-CT device.

BACKGROUND: Attenuation correction is generally used to PET images to achieve count rate values independent from tissue densities. The goal of this study was to provide a qualitative comparison of attenuation corrected PET images produced by a PET-CT device (CT, 120 kV, 40 mAs, FOV 600 mm) with and without segmentation of transmission data (ACseg+ and ACseg-respectively). Methods: The reconstructed images were compared to attenuation corrected images obtained with a high-energy transmission source (Cs-137 - 662 keV).

Animal models of shaken baby syndrome: revisiting the pathophysiology of this devastating injury.

To better understand outcomes after early brain injuries, studies must address multiple variables including age at injury, the mechanisms and severity of injury, environmental factors (before and after injury) and developmental factors. Animal models are helpful for elucidating these different aspects. First, this paper describes a new model of shaken baby syndrome (SBS) in mice, without impact or hypoxia.

Does in utero exposure to heavy maternal smoking induce nicotine withdrawal symptoms in neonates?

Maternal drug use during pregnancy is associated with fetal passive addiction and neonatal withdrawal syndrome. Cigarette smoking-highly prevalent during pregnancy-is associated with addiction and withdrawal syndrome in adults. We conducted a prospective, two-group parallel study on 17 consecutive newborns of heavy-smoking mothers and 16 newborns of nonsmoking, unexposed mothers (controls).

Neuroimaging of intraparenchymal lesions predicts outcome in shaken baby syndrome.

Objective: Studies of long-term outcome on nonaccidental head injury (NAHI) in young children have shown severe neurodevelopmental sequelae in most cases. For improving the knowledge of outcome and for identifying prognostic factors, additional clinical and cerebral imaging data are needed. The aim of this study was to describe clinical and imaging features over time and to consider their value for predicting neurodevelopmental outcome.

Delayed white matter injury in a murine model of shaken baby syndrome.

Shaken baby syndrome, a rotational acceleration injury, is most common between 3 and 6 months of age and causes death in about 10 to 40% of cases and permanent neurological abnormalities in survivors. We developed a mouse model of shaken baby syndrome to investigate the pathophysiological mechanisms underlying the brain damage. Eight-day-old mouse pups were shaken for 15 seconds on a rotating shaker.

Adenylosuccinase deficiency: an unusual cause of early-onset epilepsy associated with acquired microcephaly.

Adenylosuccinase deficiency, an autosomal recessive inborn error of purine synthesis, was first described in 1984 by Jaeken and Van den Berghe (reviewed in J Inher Metab Dis 20;1997:193). The cardinal features are variable psychomotor delay often accompanied by epilepsy and autistic features. Diagnosis is made by detection of abnormal purine metabolites in body fluids.

Glycine antagonist and NO synthase inhibitor protect the developing mouse brain against neonatal excitotoxic lesions.

The prevention of cerebral palsy and neuroprotection of the immature brain continue to be health care priorities. The pathophysiology of perinatal brain lesions associated with cerebral palsy seems to be multifactorial and includes pre- and perinatal factors such as preconceptional events, hormone and growth factors deficiencies, maternal infections with production of cytokines, and hypoxic/ischemic perfusion failures. Excitotoxic cascade could represent a common pathway that leads to neural cell death and subsequent brain damage.
