RESUMEN

BACKGROUND: Gamification of behavioral intervention for tic disorders (TDs) potentially enhances compliance and offers key clinical advantages. By delivering immediate positive feedback upon tic-suppression, games may counteract negative reinforcement, which presumably contribute to tic consolidation by relieving uncomfortable premonitory urges. OBJECTIVES: We developed a gamified protocol (XTics), which leverages this potential by combining gamified tic-triggering with immediate feedback, and evaluated its clinical value in enhancing tic suppression. METHODS: XTics encompasses two conditions: Immediate and Contingent Reward (ICR), where game progression is contingent upon successful tic suppression, and Delayed Reward (DR), where game events' outcomes are random. Employing a randomized crossover design, 35 participants (aged 7-15 years) underwent daily gaming sessions over a week per condition. Improvements in our primary measures, including the inter-tic interval (ITI) and tic severity assessment by blinded evaluators (Yale Global Tic Severity-Total Tic Score [YGTSS-TTS], Rush), and parents (Parent Tic Questionnaire [PTQ]), were compared between ICR and DR, and assessed across conditions for the 4-week protocol. RESULTS: No participant voluntarily left the study before completing its two-phase protocol. As expected, ITI showed significantly larger improvement (Z = 4.19, P = 2.85 × 10-5) after ICR (1442 ± 2250%) versus DR (242 ± 493%) training, increasing at a higher pace (t(67) = 3.15, P = 0.0025). Similarly, Rush tic severity scores reduced more post-ICR versus DR (t(47) = 3.47, P = 0.002). We observed a clinically significant reduction of 25.69 ± 23.39% in YGTSS-TTS following a f4-week protocol including both conditions. Parent-reported tic severity decreased by 42.99 ± 31.69% from baseline to 3 months post-treatment. CONCLUSIONS: The combination of gamified tic-triggering with immediate and contingent rewards demonstrates a promising approach for enhancing treatment efficacy in TDs, boosting traditional therapeutic methods. © 2024 The Author(s).

RESUMEN

BACKGROUND AND PURPOSE: Children in developed countries spend a significant portion of their waking hours engaging with audiovisual content and video games. The impact of media consumption on children's health and well-being has been widely studied, including its effects on tic disorders. Previous studies have shown that tic frequency can both increase and decrease during activities like gaming and television watching, resulting in mixed findings. METHODS: To better understand the impact of audiovisual media on tics, we conducted a fine-grained tic manifestation analysis. We focused on the effects of the impact of a movie scene with suspensful elements and a video game designed to heighten anticipation, thought to stimulate phasic and striatal dopamine release. We closely monitored tic frequency throuhghout these experiences based on moment-to-moment tic annotation. The study included 20 participants (19 males aged 7-16) diagnosed with tic disorders (Yale Global Tic Severity Scale≥8), and we tested the replicability of our findings with an independent group of 36 children (15 females, aged 7-15) with tic disorders. RESULTS: During film viewing, we observed significant synchronization in the temporal tic patterns of various individuals despite diversity in their tic profiles. Furthermore, employing a video game developed for our study, we found that tic frequency increases during anticipation of a pending reward. This finding was replicated in a second experiment with an independent cohort. CONCLUSIONS: Our results indicate that tic frequency is affected by media elements in the short-term, and call for further investigation of the long-term impacts of exposure to such tic triggers.

RESUMEN

Epilepsy and attention-deficit/hyperactivity disorder (ADHD) are closely connected and commonly seen in both children and adults. Each of the disorders has major psychosocial and quality of life (QOL) effects, and their co-occurrence makes coping even more challenging for both the patients and their families. Moreover, an adverse effect of some anti-seizure medications can potentially induce or exacerbate symptoms of ADHD on the one hand, while some ADHD medications may increase seizure risk on the other. The combination of proper diagnosis and appropriate treatment may improve or even prevent many of the complications associated with these conditions. The objectives of this review are to present the complex relationship between epilepsy and ADHD, looking into the pathophysiological, anatomical, and functional perspectives along with the psychosocial and QOL influences and the recommended treatment approaches in accordance with the latest literature.

RESUMEN

Despite increasing awareness for diagnosing autism spectrum disorder (ASD) and initiating treatments early in life, many children and adolescents continue to be diagnosed at a relatively older age. Focusing on children who first received an ASD diagnosis at age six or older, this study aimed to describe the symptoms that parents reported when ASD was diagnosed, follow the patients' clinical trajectory prior to receiving the diagnosis, and describe differences in symptoms and prior diagnoses between males and females cases. We included 258 children (205 males and 53 females) who were first diagnosed with autism at age 6-18 in 2017-2018. We retrieved demographic information, neurologic and developmental symptoms, diagnoses, and medications dispensing history from the children's electronic medical charts. The data indicated that prior diagnoses of language delays and attention deficit hyperactivity disorder were common among children with a late ASD diagnosis. Two thirds of the children were prescribed one or more medications to treat psychosocial and behavioral conditions before receiving a late ASD diagnosis. Difficulties in social relationships with peers were the leading reported symptoms by parents at the time of ASD diagnosis. Across these different domains, some differences were found between males and females, including a somewhat higher cognitive level in males, who were also more likely to present aggressive behavior.

RESUMEN

Objective: To evaluate the short-term effect of dexmethylphenidate (D-MPH) on visual acuity (VA), pupil size, anterior chamber depth, and accommodation-convergence reflex in children treated with D-MPH for attention-deficit/hyperactivity disorder (ADHD). Method: Prospective cohort study including 15 patients aged 8-16 (11.58 ± 2.39) treated with D-MPH for ADHD. Patients were questioned for subjective complaints such as blurred vision and photosensitivity. An ophthalmic evaluation was performed twice; before and 1.5 hours after D-MPH administration. The examination included evaluation of best corrected visual acuity at distance and near, accommodation range, convergence range, 3D vision test (stereopsis), and anterior segment optical coherence tomography. Results: A significant association between change in pupil diameter and D-MPH treatment dose was demonstrated (p = 0.01). In addition, a positive correlation between complaints about blurred vision and pupil's size change was found (p < 0.05). There were no significant changes in VA, convergence range, stereopsis, accommodation range, or anterior chamber measures. Conclusions: Our findings provide support for the effect of stimulants on pupil diameter in a dose-dependent manner. No clinically significant differences in visual functions were found 1.5 hours after consumption of D-MPH. Institutional review board clinical trial refference no. 0122-17-TLV.

RESUMEN

We examined group differences between parents, both mothers and fathers, of premature and full-term infants to determine whether they differed in their reports of subjective parenting stress and in their level of parental reflective functioning (PRF). We also tested whether each parent's reflective functioning moderated the links between birth status (prematurity vs. full-term) and parenting stress. A sample of 73 cohabiting, heterosexual Israeli families with a premature (28-36th week gestational age, N = 34) or full-term infant (37th week and above gestational age, N = 39) participated, comprising the two parents' groups. Infants' age averaged 7.07 months (SD = 1.28). Each parent completed the Parent Stress Inventory (PSI) individually to determine his/her subjective personal and childrearing stress levels. The Parent Development Interview (PDI-R2-S) was used to obtain each parent's PRF (self and child/relation-focused) level. Findings showed that the premature and full-term parents did not differ in their PSI scores or PRF levels. However, mothers' self-focused PRF moderated the link between prematurity and personal parenting stress, whereas fathers' self-focused PRF moderated the link between prematurity and childrearing parenting stress. Furthermore, fathers' and mothers' PRF operated differently in the premature and full-term parents' groups. The findings highlight the importance of mothers' and fathers' PRF in predicting parents' subjective stress in general and particularly in the case of infant prematurity. We discuss these findings and their relevance for preventive and therapeutic perinatal interventions.

RESUMEN

BACKGROUND: There is an increasing prevalence of developmental difficulties among Israeli children. We aimed to assess whether pediatricians are equipped to diagnose and manage them. METHODS: We assessed the knowledge of basic child development issues and availability of services and content of special education systems among a randomly selected national sample of residents and senior Israeli pediatricians. This was done via an 70-itemed survey developed especially for this study which consisted of seven main subjects: developmental milestones, global developmental delay, autism spectrum disorder, attention deficit hyperactivity disorder, protocol for referring to a child development institute, availability and facilities of special education systems, and medical conditions associated with developmental delay. RESULTS: A total of 310 pediatricians (an 86 % usable response rate) participated. The total median knowledge score was 32.1 % (IQR 17.8-53.5 %). Knowledge was significantly better among senior pediatricians (p < .001), those working in an office-based setting (p < .001), and those who were parents (p < .001) or had a family history of a developmental condition (p = .003). Most responders (94 %) felt that their resident training in child development was inadequate, and that they do not have sufficient access to resources and guidelines about child development and special education systems (80 %). CONCLUSIONS: The gap in knowledge on topics of child development and special education systems among Israeli pediatricians stems from inadequacies in the current curricula of pediatric residencies. The alarmingly low scores of our survey on these issues call for prompt revamping of the syllabus to include them.

RESUMEN

LAY ABSTRACT: The lockdown and home isolation due to the COVID-19 pandemic led to significant transformation in lifestyles. Being a parent in this situation was not easy for anyone, much less for parents of children with special needs. The shutting down of special education systems meant that parents lost a vital support network and had to be the sole full-time caregivers despite often lacking the skills to cope with this new and daunting situation. We interviewed parents and learned that the main difficulties faced by homebound autistic children stemmed from the change in routine, lack of special education services, limited physical space, and food- and sleep-related issues. Some children experienced worsening in behavioral, social, and developmental domains, yet others seemed to not only overcome the challenges of changing conditions but even benefit from them. The children's success or failure was directly related to how their parents coped. The key factors that enabled successful coping were the parents' ability to accommodate to the child's needs, their own creativeness and resourcefulness, and a generally positive outlook. The results of this analysis revealed that the best way to benefit autistic children caught up in drastic changes in their routine lifestyle is to invest in a strong support system for their parents.

RESUMEN

PURPOSE: The craniometrics of head circumference (HC) and ventricular size are part of the clinical assessment of infants with hydrocephalus and are often utilized in conjunction with other clinical and radiological parameters to determine the success of treatment. We aimed to assess the effect of endoscopic third ventriculostomy (ETV) and shunting on craniometric measurements during the follow-up of a cohort of infants with symptomatic triventricular hydrocephalus secondary to aqueductal stenosis. METHODS: We performed a post hoc analysis of data from the International Infant Hydrocephalus Study (IIHS)-a prospective, multicenter study of infants (< 24 months old) with hydrocephalus from aqueductal stenosis who were treated with either an ETV or shunt. During various stages of a 5-year follow-up period, the following craniometrics were measured: HC, HC centile, HC z-score, and frontal-occipital horn ratio (FOR). Data were compared in an analysis of covariance, adjusting for baseline variables including age at surgery and sex. RESULTS: Of 158 enrolled patients, 115 underwent an ETV, while 43 received a shunt. Both procedures led to improvements in the mean HC centile position and z-score, a trend which continued until the 5-year assessment point. A similar trend was noted for FOR which was measured at 12 months and 3 years following initial treatment. Although the values were consistently higher for ETV compared with shunt, the differences in HC value, centile, and z-score were not significant. ETV was associated with a significantly higher FOR compared with shunting at 12 months (0.52 vs 0.44; p = 0.002) and 3 years (0.46 vs 0.38; p = 0.03) of follow-up. CONCLUSION: ETV and shunting led to improvements in HC centile, z-score, and FOR measurements during long-term follow-up of infants with hydrocephalus secondary to aqueductal stenosis. Head size did not significantly differ between the treatment groups during follow-up, however ventricle size was greater in those undergoing ETV when measured at 1 and 3 years following treatment.

RESUMEN

Purpose: To examine the feasibility and efficacy of a combined motor-cognitive training using virtual reality to enhance behavior, cognitive function and dual-tasking in children with Attention-Deficit/Hyperactivity Disorder (ADHD). Methods: Fourteen non-medicated school-aged children with ADHD, received 18 training sessions during 6 weeks. Training included walking on a treadmill while negotiating virtual obstacles. Behavioral symptoms, cognition and gait were tested before and after the training and at 6-weeks follow-up. Results: Based on parental report, there was a significant improvement in children's social problems and psychosomatic behavior after the training. Executive function and memory were improved post-training while attention was unchanged. Gait regularity significantly increased during dual-task walking. Long-term training effects were maintained in memory and executive function. Conclusion: Treadmill-training augmented with virtual-reality is feasible and may be an effective treatment to enhance behavior, cognitive function and dual-tasking in children with ADHD.

RESUMEN

INTRODUCTION: One of the most important unanswered questions in pediatric hydrocephalus is determining whether treatment with endoscopic third ventriculostomy (ETV) versus shunt results in improved health status and quality of life (QOL). To answer this, the International Infant Hydrocephalus Study (IIHS) was started in 2005 as a prospective, multicenter study to compare ETV and shunt in infants (< 24 months old) with symptomatic triventricular hydrocephalus from aqueductal stenosis. Herein, we present the 5-year primary outcome results. METHODS: IIHS utilized a prospective comprehensive cohort design, in which patients received ETV or shunt, based on either randomization or parental preference. For this analysis, we pooled the randomized arm and the parental preference arm, analyzing them together. At 5 years of age, children were assessed with the Health Utilities Index Mark 2 (HUI-2) (primary outcome) and the Hydrocephalus Outcome Questionnaire (HOQ), a measure of QOL. Results were compared in an analysis of covariance, adjusting for baseline variables including age at surgery and baseline development status. RESULTS: From a total of 158 patients who met eligibility criteria, complete 5-year outcomes were available on 78 (19 treated initially with shunt, 61 treated initially with ETV), assessed at a mean age of 62.1 months (SD 6.3). The mean 5-year HUI-2 utility score was 0.90 (SD 0.19) for ETV and 0.94 (SD 0.10) for shunt (p = 0.21). The mean 5-year HOQ overall score was 0.81 (SD 0.15) for ETV and 0.85 (SD 0.12) for shunt (p = 0.42). Similarly, there were no significant differences noted between 5-year HOQ subscores (cognitive, social-emotional, physical) or developmental measures at 1, 2, and 3 years. CONCLUSIONS: This is the first prospective direct comparison of long-term outcomes of ETV and shunt for infant hydrocephalus. These results suggest that overall health status and quality of life in this cohort of infants treated for aqueductal stenosis are high, with no significant difference between those treated initially with ETV or shunt.

RESUMEN

Knowledge regarding the association between functional connectivity and white-matter (WM) maturation of motor and visual networks in preterm infants at term equivalent age (TEA) and their association with behavioral outcome is currently limited. Thirty-two preterm infants born <34 weeks gestational-age without major brain abnormalities were included in this study, underwent resting-state fMRI at TEA. Thirteen infants also underwent diffusion tensor imaging (DTI). Neurobehavioral assessments were performed at one and two years corrected age using the Griffiths Mental Developmental Scales. Functional connectivity between homolog motor and visual regions were detected, which may reflect that a level of organization in these domains is present already at TEA. DTI parameters of WM tracts at TEA demonstrated spatial-temporal variability, with the splenium of the corpus-callosum (CC) found to be the most mature fiber bundle. Correlations between DTI parameters, functional connectivity and behavioral outcome were detected, yet did not show the same pattern of diffusivity changes in the different networks. Visual functional connectivity was negatively correlated with radial-diffusivity (RD) in the optic radiation, while motor functional connectivity was positively correlated with RD in the splenium. In addition, axial-diffusivity (AD) and RD in the genu and midbody of the CC were positively correlated with neurobehavioral outcome at one and 2 years of age. This study highlights the importance of understanding the spatial-temporal changes occurring during this sensitive period of development and the potential effect of extrauterine exposure on the microstructural changes as measured by DTI; their correlation with functional connectivity; and their long term relationship with neuro-behavioral development.

RESUMEN

BACKGROUND: Six medical disciplines are responsible for assessment, diagnosis and treatment of people with attention deficiency hyperactivity disorder (ADHD) in Israel: family doctors, pediatricians, adult and child neurologists, adult and child psychiatrists. OBJECTIVES: To investigate differences in ADHD diagnostic practices between three different pediatric subspecialties in the clinical setting in order to establish a common ground for a future unified approach. METHODS: An anonymous web-based questionnaire was administered to child psychiatrists, pediatric neurologists and general pediatricians who are actively involved in ADHD diagnosis (n=104). RESULTS: Neurologists and pediatricians rarely use the mental status examination, while psychiatrists rarely perform a neurological or physical examination (P < 0.0001). A general clinical impression of learning abilities and/or neurodevelopmental skills was implemented more often by pediatric neurologists (P < 0.04). CONCLUSIONS: The significant differences found between the three medical specialties with regard to the clinical evaluation of ADHD could be attributed, at least in part, to the ambiguity of available guidelines concerning the clinical examination, and to the adherence of each specialty to its own "skills." Larger surveys in other countries should be considered and an effort made to create a common, "inter-disciplinary" ground on this important part of ADHD evaluation, differential diagnosis, and research.

RESUMEN

This case series assesses white matter microstructure of the cerebellar peduncles in 4 adolescents born preterm with enlarged ventricles and reduced white matter volume in the cerebrum but no apparent injury to the cerebellum. Subjects (ages 12-17 years, gestational age 26-32 weeks, birth weight 825-2211 g) were compared to a normative sample of 19 full-term controls (9-17 years, mean gestational age 39 weeks, mean birth weight 3154 g). Tract profiles for each of the cerebellar peduncles were generated by calculating fractional anisotropy at 30 points along the central portion of each tract. One or more case subjects exhibited higher fractional anisotropy beyond the 90th percentile in the inferior, middle, and superior cerebellar peduncles. Findings demonstrate that differences in cerebellar white matter microstructure can be detected in the absence of macrostructural cerebellar abnormalities.

RESUMEN

Intact development of cerebellar connectivity is essential for healthy neuromotor and neurocognitive development. To date, limited knowledge about the microstructural properties of the cerebellar peduncles, the major white matter tracts of the cerebellum, is available for children and adolescents. Such information would be useful as a comparison for studies of normal development, clinical conditions, or associations of cerebellar structures with cognitive and motor functions. The goal of the present study was to evaluate the variability in diffusion measures of the cerebellar peduncles within individuals and within a normative sample of healthy children. Participants were 19 healthy children and adolescents, aged 9-17 years, mean age 13.0 ± 2.3. We analyzed diffusion magnetic resonance imaging (dMRI) data with deterministic tractography. We generated tract profiles for each of the cerebellar peduncles by extracting four diffusion properties (fractional anisotropy (FA) and mean, radial, and axial diffusivity) at 30 equidistant points along each tract. We were able to identify the middle cerebellar peduncle and the bilateral inferior and superior cerebellar peduncles in all participants. The results showed that within each of the peduncles, the diffusion properties varied along the trajectory of the tracts. However, the tracts showed consistent patterns of variation across individuals; the coefficient of variation for FA across individual profiles was low (≤20%) for each tract. We observed no systematic variation of the diffusion properties with age. These cerebellar tract profiles of the cerebellar peduncles can serve as a reference for future studies of children across the age range and for children and adolescents with clinical conditions that affect the cerebellum.

RESUMEN

Small for gestational age newborns can later suffer from eating difficulties and slow growth. Nutritional preferences can be influenced by changes in sensory perception of smell and taste. To determine whether these could be detected at birth, the authors examined the different recognition pattern of smell and taste in small for gestational age newborns compared to appropriate for gestational age controls, as expressed by gusto-facial and naso-facial reflexes. The authors performed video analysis of facial expressions of 10 small for gestational age and 12 control newborns exposed to various tastes and smells. No difference in the facial recognition patterns for taste or smell was demonstrated between small for gestational age and controls, except for perception of distilled water. Newborns show recognizable patterns of facial expression in response to taste and smell stimuli. Perception of taste and smell in small for gestational age newborns is not different from controls, as measured by the method of facial recognition.

RESUMEN

Children with autism spectrum disorder (ASD) are at risk of developing nutritional deviations. Three to six year old children with ASD were compared to their typically developing siblings and to a typically developing age and gender matched control group, in order to evaluate their intake and body mass index. Nutrient intake was compared to the Dietary Reference Intake using three-day diet diaries completed by the parents. The sum percentage of nutritional deficiencies in the ASD group compared to the typical development group was 342.5% (±122.9%) vs. 275.9% (±106.8%), respectively (P=0.026). A trend toward higher deficiency in the ASD group was observed as compared to the sibling group 363% (±122.9%) vs. 283.2% (±94.7%) (P=0.071). A higher body mass index was found in the ASD group compared to their counterparts, despite their nutritional deficiencies. In conclusion, children with ASD are more likely to suffer from nutritional deficiencies despite higher body mass index.
