Hydrocortisone as an intervention for dexamethasone-induced adverse effects in pediatric patients with acute lymphoblastic leukemia: results of a double-blind, randomized controlled trial
Purpose Dexamethasone is a key component in the treatment of pediatric acute lymphoblastic leukemia (ALL), but can induce serious adverse effects. Recent studies have led to the hypothesis that neuropsychological adverse effects may be a result of cortisol depletion of the cerebral mineralocorticoid receptors. We examined whether including a physiologic dose of hydrocortisone in dexamethasone treatment can reduce neuropsychologic and metabolic adverse effects in children with ALL. Patients and Methods We performed a multicenter, double-blind, randomized controlled trial with a crossover design. Of 116 potentially eligible patients (age 3 to 16 years), 50 were enrolled and were treated with two consecutive courses of dexamethas
Fatigue mediates the relationship between emotional and cognitive functioning in children post-cancer treatment
Background/objectives: Children treated for cancer are at risk to develop cognitive problems. Insight in underlying associations with emotional functioning and fatigue can be used to optimize interventions. We therefore aim to study emotional functioning, fatigue, and cognitive functioning in children postcancer treatment and investigate whether fatigue mediates the relationship between emotional and cognitive functioning. Design/methods: Emotional functioning, fatigue, and cognitive functioning were assessed in children post-cancer treatment using subscales of the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales, Multidimensional Fatigue Scale and Cognitive Functioning Scale. A one sample t-test was used to compare outcomes with general population peers and mediation analysis was used to address the effect of fatigue on the relationship between emotional and cognitive functioning. Results: A total of 137 children (mean age: 13.6, SD ± 3.3 years; mean time since end of treatment: 7.1 months, SD ± 5.9) participated. Lower scores on emotional functioning (Cohen's d [D]: 0.4), fatigue (D: 0.8) and cognitive functioning (D: 0.6) were found (p <.001) in children post-cancer treatment than in peers. A medium association was found between emotional and cognitive functioning (standardized regression coefficient [β]: 0.27, p <.001), which was mediated by fatigue (β = 0.16). Conclusions: Outcomes on emotional and cognitive functioning are decreased and fatigue is increased in children postcancer treatment. Fatigue mediates the relationship between emotional and cognitive functioning. Our results show the importance to focus on fatigue amongst stress as a target for intervention to improve cognitive functioning
Motor Learning in Children with Neurofibromatosis Type I
The aim of this study was to quantify the frequently observed problems in motor control in Neurofibromatosis type 1 (NF1) using three tasks on motor performance and motor learning. A group of 70 children with NF1 was compared to age-matched controls. As expected, NF1 children showed substantial problems in visuo-motor integration (Beery VMI). Prism-induced hand movement adaptation seemed to be mildly affected. However, no significant impairments in the accuracy of simple eye or hand movements were observed. Also, saccadic eye movement adaptation, a cerebellum dependent task, appeared normal. These results suggest that the motor problems of children with NF1 in daily life are unlikely to originate solely from impairments in motor learning. Our findings, therefore, do not support a general dysfunction of the cerebellum in children with NF1
Long-term follow-up and treatment in nine boys with X-linked creatine transporter defect
The creatine transporter (CRTR) defect is a recently discovered cause of X-linked intellectual disability for which treatment options have been explored. Creatine monotherapy has not proved effective, and the effect of treatment with L-arginine is still controversial. Nine boys between 8 months and 10 years old with molecularly confirmed CRTR defect were followed with repeated 1H-MRS and neuropsychological assessments during 4–6 years of combination treatment with creatine monohydrate, L-arginine, and glycine. Treatment did not lead to a significant increase in cerebral creatine content as observed with H1-MRS. After an initial improvement in locomotor and personal-social IQ subscales, no lasting clinical improvement was recorded. Additionally, we noticed an age-related decline in IQ subscales in boys affected with the CRTR defect

Transient cerebellar eye closure and mutism after cerebellar tumor surgery: long-term clinical follow-up of neurologic and behavioral disturbances in a 14-year-old girl.
Transient cerebellar eye closure (TCES) is a complication of cerebellar tumor surgery in children and is almost exclusively observed in the context of the syndrome of mutism and subsequent dysarthria. As knowledge about the course of transient cerebellar eye closure is absent, we describe in detail the clinical picture in a 14-year-old girl. The process of improvement of TCES is characterized by four distinct phases, can last more than 1 month and may be associated with severe persistent cerebellar dysfunction.Case ReportsJournal Articleinfo:eu-repo/semantics/publishe
