The wide world of technological telerehabilitation for pediatric neurologic and neurodevelopmental disorders - a systematic review.

Introduction: The use of Information and Communication Technology (ICT) for assessing and treating cognitive and motor disorders is promoting home-based telerehabilitation. This approach involves ongoing monitoring within a motivating context to help patients generalize their skills. It can also reduce healthcare costs and geographic barriers by minimizing hospitalization. This systematic review focuses on investigating key aspects of telerehabilitation protocols for children with neurodevelopmental or neurological disorders, including technology used, outcomes, caregiver involvement, and dosage, to guide clinical practice and future research. Method: This systematic review adhered to PRISMA guidelines and was registered in PROSPERO. The PICO framework was followed to define the search strategy for technology-based telerehabilitation interventions targeting the pediatric population (aged 0-18) with neurological or neurodevelopmental disorders. The search encompassed Medline/PubMed, EMBASE, and Web of Science databases. Independent reviewers were responsible for selecting relevant papers and extracting data, while data harmonization and analysis were conducted centrally. Results: A heterogeneous and evolving situation emerged from our data. Our findings reported that most of the technologies adopted for telerehabilitation are commercial devices; however, research prototypes and clinical software were also employed with a high potential for personalization and treatment efficacy. The efficacy of these protocols on health or health-related domains was also explored by categorizing the outcome measures according to the International Classification of Functioning, Disability, and Health (ICF). Most studies targeted motor and neuropsychological functions, while only a minority of papers explored language or multi-domain protocols. Finally, although caregivers were rarely the direct target of intervention, their role was diffusely highlighted as a critical element of the home-based rehabilitation setting. Discussion: This systematic review offers insights into the integration of technological devices into telerehabilitation programs for pediatric neurologic and neurodevelopmental disorders. It highlights factors contributing to the effectiveness of these interventions and suggests the need for further development, particularly in creating dynamic and multi-domain rehabilitation protocols. Additionally, it emphasizes the importance of promoting home-based and family-centered care, which could involve caregivers more actively in the treatment, potentially leading to improved clinical outcomes for children with neurological or neurodevelopmental conditions. Systematic review registration: PROSPERO (CRD42020210663).

Pediatric intensive bowel continence rehabilitation training: a retrospective study to evaluate feasibility, tolerance and effectiveness.

BACKGROUND: Pediatric continence dysfunction is not uncommon. It causes long-term disability, impairing quality of life, activities and relationships with pears and can affect until adulthood. A high-risk population are children with Hirschsprung's disease and congenital anorectal malformation. Conservative medical and surgical management of continence dysfunction in this population is deeply described, while the rehabilitation issues are still unexplored. Aim of this study is to preliminary verify the feasibility, tolerance and effectiveness of an intensive technological aided and individualized pelvic floor rehabilitation program for pediatric patients. METHODS: This is a single-center, retrospective observational study. The assessment was performed by collecting demographic data, general and local physical examination and scoring assessment tools (Rintala Continence Score and Wexner Score). The study was conducted in the Rehabilitation Unit of the pediatric Giannina Gaslini Institute, a tertiary care pediatric hospital in Genoa (Italy) between September 2015 to August 2019. We enrolled 31 children; 25 male (80.6%) and six females (19%), aged between 5 and 14 years (mean age 9 years) at the beginning of the training. Twenty children (65.5%) had Hirschsprung's disease, and 11 children (34.5%) had a congenital anorectal malformation. The rehabilitation training program was customized on the compromised function, the anatomic characteristics, the child's age and compliance. The training was aimed at improving tone, strength, endurance of the pelvic floor, compliance and rectal sensitivity, and also the frequency of the bowel movements. All patients enrolled in the study underwent an intensive outpatient treatment lasted 5 days for children older than 7 years; 10 days for younger. The intensive rehabilitation treatment was followed by a continuous home training program. RESULTS: Twenty-nine children (96.8%) completed the training. A global improvement is observed in continence functioning in all the cohort at T1 (P<0.0001), maintained at T3 (P<0.0001) at both Rintala Continence Score and Wexner Score. No adverse effects have been referred. CONCLUSIONS: Our specific pediatric training program for pelvic floor rehabilitation is effective and safe for children with continence dysfunctions after pelvic surgery due to Hirschsprung's disease and anorectal malformations. The continence rehabilitation multimodal program should be integrated in the care of children with continence dysfunctions. It cooperates in the prevention of the long-term health global impairment and also in the reduction of social economic effort.

Multicentric Carpo-Tarsal Osteolysis Syndrome (MCTO) and "Function Profile": a rehabilitative approach.

BACKGROUND: Multicentric Carpo-Tarsal Osteolysis Syndrome (MCTO) is an autosomal dominant disease with increased bone reabsorption in the carpus and tarsus and the elbows, knees and spine. The disease is extremely heterogeneous and secondary and tertiary injuries vary widely and can lead to progressive disability and severe functional limitations. In addition to the available and upcoming drug therapies, physical medicine and rehabilitation are important treatment options. Currently, the indication and plan are overlooked, nonspecific and reported only for one patient. METHODS: We describe a case series of MCTO patients diagnosed and followed by a centre to identify functional deficit as a potential clinical marker of disease progression for future etiological therapies. In addition, we define a symptomatic treatment approach and specific clinical management, including a patient-centred rehabilitation approach. Functional assessments are performed independently by a multidisciplinary group to establish the functional abilities of patients and the relationship between residual motor skills and their degree of autonomy and participation. We suggest a way to identify a rehabilitation plan based on a specific disease using the International Classification of Functioning, Disability and Health Children and Youth (ICF-CY). RESULTS: To define a reliable and reproducible "Function Profile", through age and over time, we used to value the disease status according to the ICF-CY domains. It could be used to determine the complexity of the illness, its overall impact on the complexity of the person and the burden on the caregiver, and an eventual short- and long-term rehabilitation plan for MCTO and other ultra-rare diseases. CONCLUSION: Based on the MCTO experience, we suggest a way to determine a rehabilitation plan based on a specific disease and patient needs, keeping in mind that often the final point is not recovering the full function but improving or maintaining the starting point. In all cases, each patient at the time of diagnosis requires a functional assessment that must be repeated over time to adjust the course of rehabilitation. The evaluations revealed the importance of early rehabilitation management in enhancing independence, participation and control of stress deconditioning, shrinking of muscle tendons and loss of movement to immobility.

[Formula: see text] Executive functions and psychosocial impairment in children following arterial ischemic stroke.

This study examined the executive function (EF) of children with a history of arterial ischemic stroke (AIS) and preserved intellectual abilities, with reference to age at stroke onset, lesion characteristics, language, and motor functioning. In addition, the associations between EF and emotional and behavioral functioning were investigated. A battery of standardized neuropsychological tests was administered to children with previous AIS aged 7-12 in order to assess EF, including inhibition, working memory, cognitive flexibility, and attention. Parents rated questionnaires regarding real-life emotional and behavioral functioning. Finally, clinical and neuroradiological data were also gathered. Thirty patients were enrolled. Eight children fall in the lower end of the normative range or below in more than half of the EF measures, with working memory, inhibition and cognitive flexibility equally impaired, and attention relatively better preserved. Larger lesion size and language deficits were significantly associated with higher EF impairment. Emotional and behavioral functioning was lower in children with weaker EF. Children with a history of AIS, even those with preserved intellectual functioning, have a high risk of showing poor EF, mostly regardless of clinical features or functional impairment. EF difficulties are in turn associated with emotional and behavioral problems. Therefore, a standardized evaluation of EF in this population is mandatory as part of the follow-up, in order to ensure an early intervention and prevent related difficulties.

Emotional and social functioning after stroke in childhood: a systematic review.

PURPOSE: To provide an overview of the effects of pediatric stroke on emotional and social functioning in childhood. METHODS: A literature review was completed in accordance with the Preferred Reporting Items for Systematic Reviews. A systematic search of studies on internalizing problems and social functioning after pediatric stroke in PsycInfo, PsycArticles, and PubMed databases was conducted from inception to November 2021. A total of 583 studies were identified, and 32 met the inclusion criteria. RESULTS: The review suggests that children after stroke are at risk of developing internalizing problems and a wide range of social difficulties. Internalizing problems are often associated with environmental factors such as family functioning and parents' mental health. In addition, a higher risk of developing psychosocial problems is associated with lower cognitive functioning and severe neurological impairment. CONCLUSIONS: The assessment of psychological well-being and social functioning after pediatric stroke is helpful to provide adequate support to children and their families. Future studies are needed to better investigate these domains and to develop adequate methodologies for specific interventions.Implication for rehabilitationThis paper reviews research concerning emotional and social functioning following pediatric stroke in order to provide helpful information to clinicians and families and to improve rehabilitation pathways.Emotional and social functioning should be addressed during post-stroke evaluation and follow-up, even when physical and cognitive recovery is progressing well.Care in pediatric stroke should include volitional treatment and address emotional and social issues.

The Genetic Landscape of Ischemic Stroke in Children - Current Knowledge and Future Perspectives.

Stroke in childhood has multiple etiologies, which are mostly distinct from those in adults. Genetic discoveries over the last decade pointed to monogenic disorders as a rare but significant cause of ischemic stroke in children and young adults, including small vessel and arterial ischemic stroke. These discoveries contributed to the understanding that stroke in children may be a sign of an underlying genetic disease. The identification of these diseases requires a detailed medical and family history collection, a careful clinical evaluation for the detection of systemic symptoms and signs, and neuroimaging assessment. Establishing an accurate etiological diagnosis and understanding the genetic risk factors for stroke are essential steps to decipher the underlying mechanisms, optimize the design of tailored prevention strategies, and facilitate the identification of novel therapeutic targets in some cases. Despite the increasing recognition of monogenic causes of stroke, genetic disorders remain understudied and therefore under-recognized in children with stroke. Increased awareness among healthcare providers is essential to facilitate accurate diagnosis in a timely manner. In this review, we provide a summary of the main single-gene disorders which may present as ischemic stroke in childhood and describe their clinical manifestations. We provide a set of practical suggestions for the diagnostic work up of these uncommon causes of stroke, based upon the stroke subtype and imaging characteristics that may suggest a monogenic diagnosis of ischemic stroke in children. Current hurdles in the genetic analyses of children with ischemic stroke as well as future prospectives are discussed.

An Atypical Case of Aphasia: Transitory Ischemic Attack in a 13-Year-Old Patient with Asymptomatic SARS-CoV-2 Infection.

We report the case of a 13-year-old patient, female, born in Northern Italy, who presented with an acute episode of aphasia, lasting about 15 min, accompanied by left arm dysesthesia. The state of consciousness remained preserved throughout the episode. After a first clinical evaluation at second-level hospital, the patient was sent to our institute for further investigations. Brain MRI performed at admission showed no noteworthy structural alterations. Electroencephalogram was not significant, as was the echocardiographic examination. ECG was normal, except for a corrected-QT at the upper limits of the normal range for age and gender. The neurological examination was substantially normal for the entire duration of the hospital stay. The symptomatology initially described has never reappeared. Blood tests were substantially negative, in particular thrombophilic screening excluded hereditary-familial thrombophilic diseases. Color doppler ultrasound of the supra-aortic trunks, splanchnic vessels and lower limbs were also normal. Only positivity to SARS-CoV-2 serology is reported. In the recent clinical history there were no symptoms attributable to symptomatic coronavirus infection.

Genotype-Phenotype Correlation and Functional Insights for Two Monoallelic TREX1 Missense Variants Affecting the Catalytic Core.

The TREX1 exonuclease degrades DNA to prevent aberrant nucleic-acid sensing through the cGAS-STING pathway, and dominant Aicardi-Goutières Syndrome type 1 (AGS1) represents one of numerous TREX1-related autoimmune diseases. Monoallelic TREX1 mutations were identified in patients showing early-onset cerebrovascular disease, ascribable to small vessel disease, and CADASIL-like neuroimaging. We report the clinical-neuroradiological features of two patients with AGS-like (Patient A) and CADASIL-like (Patient B) phenotypes carrying the heterozygous p.A136V and p.R174G TREX1 variants, respectively. Genetic findings, obtained by a customized panel including 183 genes associated with monogenic stroke, were combined with interferon signature testing and biochemical assays to determine the mutations' effects in vitro. Our results for the p.A136V variant are inconsistent with prior biochemistry-pathology correlates for dominant AGS-causing TREX1 mutants. The p.R174G variant modestly altered exonuclease activity in a manner consistent with perturbation of substrate interaction rather than catalysis, which represents the first robust enzymological data for a TREX1 variant identified in a CADASIL-like patient. In conclusion, functional analysis allowed us to interpret the impact of TREX1 variants on patients' phenotypes. While the p.A136V variant is unlikely to be causative for AGS in Patient A, Patient B's phenotype is potentially related to the p.R174G variant. Therefore, further functional investigations of TREX1 variants found in CADASIL-like patients are warranted to determine any causal link and interrogate the molecular disease mechanism(s).

Combined medical therapy and neurosurgical revascularization preventing stroke in post-varicella angiopathy: Case report and review of literature.

BACKGROUND: Post varicella angiopathy (PVA) is an underdiagnosed but potentially severe disease in both pediatric and adult settings. No guidelines are available for the medical and neurosurgical management of this condition. We report the first pediatric case with headache and PVA who was treated with surgical revascularization before the onset of ischemic events. METHODS: This case report was conducted via retrospective chart review. A literature review was also completed, in order to identify previously described PVA undergone to revascularization. RESULTS: We report on a 9-year-old boy presenting with a long history of headache and PVA involving the distal left middle cerebral artery. The arterial lesion rapidly worsened over a 10 months' period with formation of focal moyamoya-like collaterals, despite an adequate intravenous antiviral treatment. The pattern of headaches significantly changed with a clear left-side lateralization and a "re-build-up" phenomenon on EEG. The patient was treated with left superficial temporal artery - middle cerebral artery (STA-MCA) bypass and encephalo-duro-arterio-myo-pericranial-synangiosis. This combined treatment resulted in an immediate and persistent improvement of brain perfusion, accompanied by prompt resolution of neurological symptoms. Two cases who presented with Suzuki stage III (unilateral or bilateral) moyamoya PVA and recurrent strokes or transient ischemic attacks despite adequate pharmacological prophylaxis have been surgically treated using both indirect and direct revascularization technique. The outcome was good in both cases. CONCLUSION: Surgical revascularization may have a role in the treatment of PVA and may prevent stroke. Given the lack of standardized treatment algorithms, individualized regimens should be formulated on a case-specific basis.

Expanding the clinical and neuroimaging features of post-varicella arteriopathy of childhood.

OBJECTIVE: Post-varicella arterial ischemic stroke (AIS) is considered an uncommon cause of pediatric stroke that is considered a self-limiting, monophasic disease. However, in a subset of patients, disease recurs; the prevalence of vasculopathy or AIS recurrence, severity of clinical outcomes, and standardized therapies have not been well characterized. Herein, we determined the clinical-neuroradiological features, long-term evolution, and relationship between acute phase treatment and vasculopathy recurrence in a pediatric population with post-varicella AIS. METHODS: Clinical, laboratory, and neuroradiological features of 22 children with post-varicella AIS between 2010 and 2019 (16 males, mean age at stroke 4 years, range 1.7-10) were reviewed. Statistical analyses were performed using χ2 and Fisher exact tests. RESULTS: Of the 22 cases, mean time from varicella to stroke was 4.5 months with 3 cases presenting more than 12 months after rash; 21 (95%) were not vaccinated for varicella; 3 (13.6%) had posterior circulation involvement; and 5 (22.7%) had AIS or vasculopathy recurrence, of which 4 recurred 6.1 months to 2.8 years after initial clinical onset. Recurrence was associated with lack of antiviral treatment during the first episode (p = 0.02). CONCLUSIONS: Post-varicella AIS can occur months after rash making diagnosis challenging. Because recurrent vasculopathy was seen predominantly in cases not treated with antiviral therapy during initial presentation, it is important to rapidly diagnose post-varicella AIS through clinical criteria and/or virological testing then treat with antivirals to prevent recurrence.

A prediction rule for polyarticular extension in oligoarticular-onset juvenile idiopathic arthritis.

OBJECTIVES: To search for predictors of polyarticular extension in children with oligoarticular-onset juvenile idiopathic arthritis (JIA) and to develop a prediction model for an extended course. METHODS: The clinical charts of consecutive patients with oligoarticular-onset JIA and ≥2 years of disease duration were reviewed. Predictor variables included demographic data, number and type of affected joints, presence of iridocyclitis, laboratory tests including antinuclear antibodies, and therapeutic interventions in the first 6 months. Joint examinations were evaluated to establish whether after the first 6 months of disease patients had persistent or extended course (i.e. involvement of 4 or less, or 5 or more joints). Statistics included univariable and multivariable analyses. Regression coefficients (ß) of variables that entered the best-fitting logistic regression model were converted and summed to obtain a "prediction score" for an extended course. RESULTS: A total of 480 patients with a median disease duration of 7.4 years were included. 61.2% had persistent oligoarthritis, whereas 38.8% experienced polyarticular extension. On multivariable analysis, independent correlations with extended course were identified for the presence of ≥2 involved joints and a CRP >0.8 mg/dl in the first 6 months. The prediction score ranged from 0 to 6 and its cut-off that discriminated best between patients who had or did not have polyarticular extension was >1. Sensitivity and specificity were 59.6 and 79.8, respectively. CONCLUSIONS: The number of affected joints and the CRP level in the first 6 months were the strongest predictors of polyarticular extension in our children with oligoarticular-onset JIA.

Spontaneous movements in the newborns: a tool of quantitative video analysis of preterm babies.

BACKGROUND AND OBJECTIVES: The number of preterm babies is steadily growing world-wide and these neonates are at risk of neuro-motor-cognitive deficits. The observation of spontaneous movements in the first three months of age is known to predict such risk. However, the analysis by specifically trained physiotherapists is not suited for the clinical routine, motivating the development of simple computerized video analysis systems, integrated with a well-structured Biobank to make available for preterm babies a growing service with diagnostic, prognostic and epidemiological purposes. METHODS: MIMAS (Markerless Infant Movement Analysis System) is a simple, low-cost system of video analysis of spontaneous movements of newborns in their natural environment, based on a single standard RGB camera, without markers attached to the body. The original videos are transformed into binarized sequences highlighting the silhouette of the baby, in order to minimize the illumination effects and increase the robustness of the analysis; such sequences are then coded by a large set of parameters (39) related to the spatial and spectral changes of the silhouette. The parameter vectors of each baby were stored in the Biobank together with related clinical information. RESULTS: The preliminary test of the system was carried out at the Gaslini Pediatric Hospital in Genoa, where 46 preterm (PT) and 21 full-term (FT) babies (as controls) were recorded at birth (T0) and 8-12 weeks thereafter (T1). A simple statistical analysis of the data showed that the coded parameters are sensitive to the degree of maturation of the newborns (comparing T0 with T1, for both PT and FT babies), and to the conditions at birth (PT vs. FT at T0), whereas this difference tends to vanish at T1. Moreover, the coding method seems also able to detect the few 'abnormal' preterm babies in the PT populations that were analyzed as specific case studies. CONCLUSIONS: Preliminary results motivate the adoption of this tool in clinical practice allowing for a systematic accumulation of cases in the Biobank, thus for improving the accuracy of data analysis performed by MIMAS and ultimately allowing the adoption of data mining techniques.

Analysis of arthritis flares after achievement of inactive disease with methotrexate monotherapy in juvenile idiopathic arthritis.

OBJECTIVES: To investigate the frequency of arthritis flare and factors affecting occurrence of flare in children with juvenile idiopathic arthritis (JIA) who achieved inactive disease (ID) with methotrexate (MTX) monotherapy. METHODS: A total of 217 patients were included. The modality of treatment discontinuation, time of MTX withdrawal, and disease course were examined retrospectively. For each patient, the first episode of ID after MTX start was evaluated. Patient follow-up was censored at occurrence of flare or at last visit with persistent ID. RESULTS: 170 patients (78.3%) had arthritis flare after a median of 1.6 years, whereas 47 (21.7%) maintained ID until last visit, after a median of 3 years. 54.2% of patients had discontinued MTX after ID, whereas 45.8% were still receiving MTX at the time of study censoring. Among patients who had MTX withdrawn, the median interval between ID and MTX stop was 1.5 years. Occurrence of flare was more common in patients who were still receiving MTX at study censoring than in those who had discontinued MTX (p<0.001). Most patients (78.8%) had MTX tapered over time by increasing the interval between doses. Tapering modality was comparable between patients with flare and persistent ID. Only 7.7% of the patients had a biologic DMARD started at the time of flare. CONCLUSIONS: Our results confirm that children with JIA who achieve ID with MTX monotherapy have a high risk of arthritis flare. The risk of flare was independent of withdrawal strategy. Most flare episodes were not treated with biologic therapy.

Targeted re-sequencing in pediatric and perinatal stroke.

Pediatric and perinatal stroke can present as an early symptom in undiagnosed syndromes characterized by simple Mendelian inheritance. In order to diagnose those patients affected with a monogenic disorder in which an arterial cerebrovascular event or arteriopathy may have preceded any other specific symptom, we aimed to establish and validate a targeted gene panel, and to determine its diagnostic yield and clinical utility. To this end, thirty-eight patients were selected with heterogeneous cryptogenic stroke phenotypes, mostly including multiple and recurrent ischemic or hemorrhagic arterial strokes and porencephalies, variably associated with calcifications, intracranial or systemic steno-occlusive arteriopathies, positive family history, and syndromic conditions. Clinical and neuroradiological data were collected for every patient enrolled in the study, and DNA samples were tested by means of a customized gene panel including 15 genes associated with known genetic diseases related to pediatric stroke. In four patients (10.5%) the analyses unraveled pathogenetic variants in ABCC6 and COL4A1 genes, leading to a definite genetic diagnosis with a great beneficial impact on patients management, while results were null in the remaining patients. These findings suggest a high complexity and variability of the included stroke phenotypes, that could not be fully accounted for by the genes tested in the present study. A wider gene panel or an unbiased genomic approach may be better suited and advisable to explain a greater proportion of pediatric and perinatal stroke events.
