Pediatrician and parental evaluation of child neurodevelopment at 2 years of age.

BACKGROUND: The early identification of infants with a risk for neurodevelopmental disorders in the first few years of life is essential for better developmental outcomes. Screenings should be carried out by combining the family pediatricians' and parents' perspectives, the two fundamental sources of information on children's health. The present study has three aims: (a) to test the feasibility of parent-report instruments to detect warning signs in their children's development; (b) to ascertain whether there is an agreement between the family pediatricians' (FP) clinical judgments of warning signs and the parental perceptions; (c) to determine whether there is a link between parents' distress and child development. METHODS: Within the NASCITA birth cohort, in addition to the family pediatrician's clinical evaluation with routine tools, the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) was completed by parents to assess the child's language, social skills, behavior, and sensory areas. Parents were also asked to complete the Parenting Stress Index, Short Form (PSI-SF) to verify the magnitude of stress in the parent-child system. Univariate and multivariate analyses were performed to evaluate the association between child and parental characteristics and the presence of warning signs. RESULTS: The follow-up assessment was completed for 435 infants: 69 (15.8%) presented warning signs: 43 in the pediatrician's assessment and 36 in the M-CHAT-R (10 in both). A total of 16 children (14 with warning signs) received a diagnosis after a specialist evaluation. Being male (OR 2.46, 95%CI: 1.23-4.91) and having sleep disorders (OR 2.43, 95% CI 1.17-5.04) was associated with a greater likelihood of warning signs in the multivariate analysis, while reading aloud was a protective factor (not exposed versus exposed (OR = 3.14; 95% CI 1.60-6.17). For 73 children (18.4%), at least one parent tested positive for PSI-SF. An increased prevalence of parental distress was observed in children with warning signs (OR 2.36, 95% CI 1.27-4.37). CONCLUSIONS: Integrating physician and parental perspectives during well-child visits and in clinical practice appears feasible and can improve the identification of children at risk of developmental disorders.

Distance Learning in Children with and without ADHD: A Case-control Study during the COVID-19 Pandemic.

OBJECTIVE: This research involved the parents of ADHD students to explore how their children coped with online distance learning during COVID-19 pandemic and what implications this schooling method had on their emotional and behavioral well-being. METHOD: Data were collected during lockdown using an online questionnaire addressed to 100 mothers and were compared with 184 matched controls from a national survey launched in the same period. RESULTS: Attention span, spontaneous commitment, and autonomy in distance learning was found to be more limited in ADHD group. Compared to controls, 21.7% of ADHD students were not assessed and 40.9% did not receive grades. Behavioral changes were reported in both groups (64.2%), represented mainly by restlessness, aggressiveness, and anxiety. CONCLUSION: Distance education increases academic difficulties, especially in ADHD pupils. The effects of lockdown should be adequately evaluated upon school reopening and appropriate recovery interventions should be planned.

Being adults with cerebral palsy: results of a multicenter Italian study on quality of life and participation.

Cerebral palsy (CP) is still the most common cause of disability developing in infancy. How such a complex disorder affects adult life raises important questions on the critical issues to consider and the most appropriate care pathway right from early childhood. We conducted a multicenter study on a sample of 109 individuals with CP followed up from infancy and recalled for an assessment at ages ranging between 18 and 50 years (mean age 26 years). Semi-structured interviews and specific questionnaires (SF36, LIFE-H and Hollingshead Index) were conducted to assess general psychological state, quality of life, and socio-economic conditions. Our findings showed a globally positive perception of quality of life, albeit with lower scores for physical than for mental health. Our cases generally showed good scores on participation scales, though those with more severe forms scored lower on parameters such as mobility, autonomy, and self-care. These findings were investigated in more depth in interviews, in which our participants painted a picture showing that gradual improvements have been made in several aspects over the years, in the academic attainment and employment, for instance. On the downside, our sample reported persistent limitations on autonomy in daily life. As for the more profound psychological domain, there was evidence of suffering due to isolation and relational difficulties in most cases that had not emerged from the questionnaires. Our data have possible implications for the management of CP during childhood, suggesting the need to avoid an exclusive focus on motor function goals, and to promote strategies to facilitate communication, participation, autonomy, and social relations.

Heterozygous KIF1A variants underlie a wide spectrum of neurodevelopmental and neurodegenerative disorders.

BACKGROUND: Dominant and recessive variants in the KIF1A gene on chromosome 2q37.3 are associated with several phenotypes, although only three syndromes are currently listed in the OMIM classification: hereditary sensory and autonomic neuropathy type 2 and spastic paraplegia type 30, both recessively inherited, and mental retardation type 9 with dominant inheritance. METHODS: In this retrospective multicentre study, we describe the clinical, neuroradiological and genetic features of 19 Caucasian patients (aged 3-65 years) harbouring heterozygous KIF1A variants, and extensively review the available literature to improve current classification of KIF1A-related disorders. RESULTS: Patients were divided into two groups. Group 1 comprised patients with a complex phenotype with prominent pyramidal signs, variably associated in all but one case with additional features (ie, epilepsy, ataxia, peripheral neuropathy, optic nerve atrophy); conversely, patients in group 2 presented an early onset or congenital ataxic phenotype. Fourteen different heterozygous missense variants were detected by next-generation sequencing screening, including three novel variants, most falling within the kinesin motor domain. CONCLUSION: The present study further enlarges the clinical and mutational spectrum of KIF1A-related disorders by describing a large series of patients with dominantly inherited KIF1A pathogenic variants ranging from pure to complex forms of hereditary spastic paraparesis/paraplegias (HSP) and ataxic phenotypes in a lower proportion of cases. A comprehensive review of the literature indicates that KIF1A screening should be implemented in HSP regardless of its mode of inheritance or presentations as well as in other complex neurodegenerative or neurodevelopmental disorders showing congenital or early onset ataxia.

A Case of Severe Early-Onset Neuropathy Caused by a Compound Heterozygous Deletion of the PMP22 Gene: Clinical and Neurographic Aspects.

Heterozygous deletions of the gene PMP22 are associated to hereditary neuropathy with liability to pressure palsies (HNPP), a demyelinating neuromuscular disease causing variable transitory focal muscles weakness. Deletions involving both copies of PMP22 cause more severe phenotypes, with early-onset neuropathy and impairment in motor development. We report a patient with a severe early-onset demyelinating neuropathy, caused by two different inherited deletions of PMP22, whose parents had an HNPP. The patient showed neurological signs and delay in motor development but normal intellective abilities. A motor and sensitive conduction study showed severe signs of demyelination, suggestive for Dejerine Sottas Syndrome (DSS). The patient's father had a typical HNPP caused by a heterozygous 17p11.2 deletion, encompassing PMP22. The patient's mother reported no neuropathic symptoms, but in a nerve conduction studies, parents and several relatives showed signs of sensory-motor deficit with focal slowing of conduction at common sites of entrapment. Quantitative analysis of PMP22, performed in our patient by multiplex ligation-dependent probe amplification, revealed a compound heterozygous status with the same deletion of the father and a deletion of PMP22 exon 5, after proved to be inherited from the mother. Therefore, when we face an early-onset, severe form of neuropathy, we have to consider rare forms of hereditary neuropathy caused by homozygous or compound heterozygous mutations in PMP22, even if parents are asymptomatic; an exhaustive family history and an electrodiagnostic study are essential to guide genetic tests and to make a diagnosis.
