Leukodystrophies are genetic diseases affecting the white matter and leading to early death. Our objective was to determine leukodystrophy incidence, using genomics sequencing databases allele frequencies of disease-causing variants.

From 49 genes, representing the standardly defined group of leukodystrophies, we identified potential disease-causing variants from publications in the Human Genetic Mutation Database and from predictions in the Genome Aggregation Database. Allele frequencies were estimated from Genome Aggregation Database. Allele frequencies for each gene were summed to generate a super allele frequency and we used the Hardy-Weinberg equation to calculate overall expected live birth incidence associated with the gene in question.

We identified 4564 pathogenic variants for 25 discrete leukodystrophies. The largest effect was from GALC variants (Krabbe disease), which had a predicted incidence of one in 12,080 live births, 8.3 times higher than published estimates. The second most frequently predicted leukodystrophy was the RNA polymerase III-related disorders, which had an incidence of 126,160. Overall, we found a leukodystrophy incidence of 1 in 4733 live births, significantly higher than previous estimates.

Our data are consistent with a significant underdiagnosis of leukodystrophy patients. Tamoxifen An intriguing additional consideration is that there may be genetic modifiers that lead to weaker, absent, or adult-onset disease phenotypes.

The prevalence of cancer among children with stroke is unknown. This study sought to evaluate cancer- and tumor-associated childhood ischemic stroke in a multinational pediatric stroke registry.

Children aged 29days to less than 19years with arterial ischemic stroke or cerebral sinovenous thrombosis enrolled in the International Pediatric Stroke Study between January 2003 and June 2019 were included. Data including stroke treatment and recurrence were compared between subjects with and without cancer using Wilcoxon rank sum and chi-square tests.

Cancer or tumor was present in 99 of 2968 children (3.3%) with arterial ischemic stroke and 64 of 596 children (10.7%) with cerebral sinovenous thrombosis. Among children in whom cancer type was identified, 42 of 88 arterial ischemic stroke cases (48%) had brain tumors and 35 (40%) had hematologic malignancies; 45 of 58 cerebral sinovenous thrombosis cases (78%) had hematologic malignancies and eight (14%) had brain tumors. Of 54 cancer-associated arterial ischemic stroke cases with a known cause, 34 (63%) were due to arteriopathy and nine (17%) were due to cardioembolism. Of 46 cancer-associated cerebral sinovenous thrombosis cases with a known cause, 41 (89%) were related to chemotherapy-induced or other prothrombotic states. Children with cancer were less likely than children without cancer to receive antithrombotic therapy for arterial ischemic stroke (58% vs 80%, P=0.007) and anticoagulation for cerebral sinovenous thrombosis (71% vs 87%, P=0.046). Recurrent arterial ischemic stroke (5% vs 2%, P=0.04) and cerebral sinovenous thrombosis (5% vs 1%, P=0.006) were more common among children with cancer.

Cancer is an important risk factor for incident and recurrent childhood stroke. Stroke prevention strategies for children with cancer are needed.

Immune effector cell-associated neurotoxicity syndrome (ICANS) is frequently encountered in the postinfusion period of CD19-targeted chimeric antigen receptor-T cell therapy and in some cases may be fatal. Knowledge related to the spectrum of imaging findings of CD19-targeted CAR-T cell therapy-related ICANS is, however, still very much lacking, underscoring the need for continued research in this area. In this review, we hope to provide an overview of current knowledge and provide an in-depth literature review related to this topic. A brief discussion of possible imaging differential diagnoses, specifically in children with acute lymphoblastic leukemia, will also be included. Illustrative cases for each imaging phenotype will be provided to facilitate a better understanding. A greater level of insight of the spectrum of imaging findings related to ICANS will improve patients' management and enhance efforts to safely deliver CAR-T cell immunotherapy. It will also facilitate further studies to derive mechanistic insights of ICANS and potentially assist in the testing and monitoring of therapeutic interventions.
Alternating hemiplegia of childhood often manifests severe or extreme behavioral problems, the nature of which remains to be fully characterized.

We analyzed 39 consecutive patients with alternating hemiplegia of childhood for occurrence of behavioral problems and categorized those by severity mild (not requiring intervention), moderate (requiring intervention but no risk), severe (minor risk to self, others, or both), and extreme (major risk). We then analyzed behavioral manifestations, concurrent morbidity, and medication responses in patients with severe or extreme symptoms.

Two patients had mild behavioral problems, five moderate, 10 severe, six extreme, and 16 none. Extreme cases exhibited disruptive behaviors escalating to assaults. Triggers, when present, included peer-provocation, low frustration tolerance, limits set by others, and sleep disruption. Reversible psychotic symptoms occurred in two patients in one triggered by infection and trihexyphenidyl, and in another triggered by sertraline. Of the 16 patients with severe or extreme symptoms, 13 had concurrent neuropsychiatric diagnoses.
