A novel KCNQ3 mutation in familial epilepsy with focal seizures and intellectual disability
2015
Mutations in the KCNQ2 gene encoding for voltage-gated potassium channel subunits have been found in patients affected with early onset epilepsies with wide phenotypic heterogeneity, ranging from benign familial neonatal seizures (BFNS) to epileptic encephalopathy with cognitive impairment, drug resistance, and characteristic electroencephalography (EEG) and neuroradiologic features. By contrast, only few KCNQ3 mutations have been rarely described, mostly in patients with typical BFNS. We report clinical, genetic, and functional data from a family in which early onset epilepsy and neurocognitive deficits segregated with a novel mutation in KCNQ3 (c.989G>T; p.R330L). Electrophysiological stu…
Primary nocturnal enuresis and learning disability
2011
"AIM: Primary nocturnal enuresis (PNE) is the most common sleep disorder in developmental age, with a prevalence of 6-10% between 5 and 16 years of age, impacting on normal emotional and relational developing. Assessing the prevalence of mild learning disorders in enuretic children and the role of enuresis as risk factor to develop them.. . METHODS: Twenty-five patients (14 males) aged 7.59 referred for primary nocturnal enuresis to Sleep Disorder Center for developmental age and Nocturnal Enuresis of Second University of Naples (frequency ≥3\/week), were enrolled in study. Reading abilities were evaluated using MT (Memory and Learning Transfer) and cognitive performance was assessed using …
Metabolomics Study of Urine in Autism Spectrum Disorders Using a Multiplatform Analytical Methodology
2015
International audience; Autism spectrum disorder (ASD) is a neurodevelopmental disorder with no clinical biomarker. The aims of this study were to characterize a metabolic signature of ASD and to evaluate multiplatform analytical methodologies in order to develop predictive tools for diagnosis and disease follow-up. Urine samples were analyzed using (1)H and (1)H-(13)C NMR-based approaches and LC-HRMS-based approaches (ESI+ and ESI- on HILIC and C18 chromatography columns). Data tables obtained from the six analytical modalities on a training set of 46 urine samples (22 autistic children and 24 controls) were processed by multivariate analysis (orthogonal partial least-squares discriminant …
Meconial peritonitis in a rare association of partial ileal apple-peel atresia with small abdominal wall defect.
2014
Intestinal atresia type III B (apple peel) and gastroschisis are both congenital malformations who require early surgical correction in neonatal age. Their association is very rare. We present the case of a full term infant with partial apple peel ileal atresia and a small defect of the anterior abdominal wall, complicated by in utero intestinal perforation and subsequent meconial peritonitis. We observed a partial atresia of small intestine, with involvement of terminal ileus savings of jejunum and a large part of the proximal ileum, small anterior abdominal wall defect with herniation of few bowel loops, intestinal malrotation. Paralytic ileus and infections are the main causes of morbidi…
Emotional–Behavioral Disorders in Healthy Siblings of Children with Neurodevelopmental Disorders
2020
Background and Objectives: Siblings of disabled children are more at risk of developing mental illnesses. More than 50 international studies show that about 8% of children and adolescents suffer from a mental disorder, which is almost always a source of difficulties both at the interpersonal level (in the family and with peers) and at school. Healthy siblings of children with disabilities are one of the groups most at risk for consequences in psychological health and well-being. As some authors suggest, siblings build their idea of &ldquo
Recurrent missense variant in the nuclear export signal of FMR1 associated with FXS-like phenotype including intellectual disability, ASD, facial abn…
2021
Fragile X syndrome (FXS; MIM 300624) is an X-linked genetic disorder characterized by physical abnormalities associated with intellectual disability and a wide spectrum of neurological and psychiatric impairments. FXS occurs more frequently in males, 1 in 5000 males and 1 in 8000 females accounting for 1-2% of overall intellectual disability (ID). In more than 99% of patients, FXS results from expansions of a CGG triplet repeat (>200 in male) of the FMR1 gene. In the last years an increasing number, albeit still limited, of FXS subjects carrying FMR1 mutations including deletions, splicing errors, missense, and nonsense variants was reported. Nevertheless, the studies concerning the func…
Axonal pathology of the skin in infantile neuroaxonal dystrophy.
1987
Ultrastructural studies on the skin of two patients affected by infantile neuroaxonal dystrophy (INAD) were performed to evaluate its diagnostic value and to discuss the etiology of INAD. While the majority of terminal axons around intradermal glands were dystophic consisting of tubulomembranous and tubulovesicular profiles sometimes accompanied by synaptic vesicles, there were only few dystophic axons inside intradermal nerve bundles. These observations suggest that the primary lesion of INAD is located in terminal and presynaptic axons. Therefore, terminal axons have to be investigated when a diagnostic skin biopsy is performed in INAD.
Prenatal diagnosis of infantile neuronal ceroid-lipofuscinosis: a combined electron microscopic and molecular genetic approach.
1995
Based on two unrelated index patients afflicted with INCL, fetal chorion tissues were studied from subsequent pregnancies of the two respective mothers resulting in the prenatal diagnosis of INCL in two of the three pregnancies. Documentation of INCL was based on electron microscopy and DNA studies of the biopsied chorion tissue, later confirmed in the two affected fetuses after termination of their pregnancies by demonstrating INCL-specific lipopigments in post-mortem tissues, in the liver of both aborted fetuses and, additionally, in spleen and skeletal muscle of one of the affected fetuses. The autolysis of the aborted tissues, however, precluded a systematic documentation of all affecte…
Electron microscopic observation of tonsillar tissue as a diagnostic aid in early juvenile neuronal ceroid-lipofuscinosis.
1987
An electron microscopic observation in a tonsil of a patient with early juvenile neuronal ceroid-lipofuscinosis (NCL) demonstrated characteristic lipopigments in lymphocytes, i.e., fingerprint profiles (FPP) and granular matrixes. While numerous FPP, curvilinear profiles (CLP) and granular matrixes were found in reticulo-endothelial and plasma cells, tonsillar lymphocytes contained only FPP and granular matrixes as seen in circulating lymphocytes. These findings suggest that a tonsil biopsy, an easy and simple technique, may provide more reliable information than a skin biopsy not only for the diagnosis of but also for differentiating the clinical forms of childhood NCL.
Infantile neuroaxonal dystrophy: Diagnosis by skin biopsy
1991
A child who shows progressive motor and mental deterioration after the first year of life, who has pyramidal signs, marked muscle hypotonia, but no seizures, suggests to have infantile neuroaxonal dystrophy (INAD). Beyond the age of two years, the EEG also entails characteristic findings. Diagnosis may be obtained by an ultrastructural examination of biopsied skin. The respective clinical and morphological findings are recorded and illustrated from four patients in this report.
