BACKGROUND: Few population-based surveys of childhood arterial ischemic stroke (AIS) have been conducted in Asian countries. The aim of this study was to investigate the clinical features, time to diagnosis, and prognosis of childhood AIS in a population-based cohort in Japan. METHODS: Children aged 29 days-15 years 11 months old, residing in the Aichi Prefecture of Japan with radiologically confirmed AIS during 2010-2014, were identified retrospectively through questionnaires. We analyzed 40 children (23 boys, 17 girls; median age, 7 years 3 months), and collected time interval information of 26 patients. The time from clinical onset to first physician assessment and the time to AIS diagnosis were calculated. RESULTS: The most common presentation was paralysis or paresis in 27 patients (71%). No underlying disorders or possible trigger factors were identified in 14 patients (35%). The median time from symptom onset to first physician assessment was 2.9 h. The median time from symptom onset to the confirmed AIS diagnosis was 27.0 h. The diagnosis of AIS was made in the first 6 h after onset of symptoms in 27% of patients for whom the time was available. Radiological diagnosis took longer than 24 h in 54% of these patients. CONCLUSIONS: Long in-hospital delays exist in the diagnosis of AIS in children, likely due to lack of awareness of stroke by doctors. Further efforts to increase public and physician awareness of childhood stroke are needed to ensure early diagnosis and treatment.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Many small for gestational age (SGA) infants have catch-up growth during the first 2 years of life, but approximately 10% have no catch-up growth, and short stature continues into adulthood. Identification of risk factors for absence of catch-up growth at an early age may be useful for earlier diagnosis and earlier treatment. METHODS: This was a retrospective multicenter study. The subjects were SGA infants with very low-birthweight (VLBW), who were followed up until the age of 3 years. The risk factors for absence of catch-up growth were identified on statistical analysis. RESULTS: Of the 217 SGA infants in this study, 181 were in the catch-up group and 36 were in the no catch-up group. The catch-up rate was 83%. On multivariate analysis adjusted for gestational age, birthweight, birth height, and birth head circumference, multipara, Z and ΔZ scores of length at 12 months of corrected age, and the Z score of height at 24 months of corrected age were risk factors for lack of catch-up at 3 years. CONCLUSIONS: The length Z and ΔZ scores at 12 months of corrected age may be useful for an earlier diagnosis and earlier initiation of growth hormone treatment in VLBW infants.

Language：English Publishing type：Research paper (scientific journal)

There have been increasing number of reports of SZT2-related neurological diseases, the main symptoms of which are epilepsy, developmental delay, macrocephaly and a dysmorphic corpus callosum. SZT2 functions as a regulator of mechanistic target of rapamycin complex 1 (mTORC1) signaling in cultured human cell lines and mouse tissues. However, it remains to be determined whether mutations in SZT2 in human patients alter mTORC1 signaling. In this study, we aimed to investigate the functional consequence of biallelic SZT2 variants in Epstein-Barr virus-induced lymphoblastoid cell lines (LCLs) established from two patients with a typical SZT2-related neurodevelopmental disease. Increased phosphorylation of S6 kinase and S6 was identified in patient-derived cell lines under amino acid-starved condition, suggestive of constitutive hyperactivation of mTORC1 signaling. This result was validated by constitutive lysosomal localization of mTOR in patients' LCLs. Furthermore, patients' LCLs display an excessive response to slight amino acid stimulation. Our data suggest the loss-of-function nature of SZT2 mutations in the patients, and consequent hyperactivation of mTORC1 signaling in response to both amino acid starvation and stimulation in their LCLs. By these functional analyses, the pathogenicity of newly identified SZT2 variants can be determined, allowing for more detailed characterization of genotype-phenotype correlations.

Reduced-intensity conditioning is widely used with hematopoietic stem cell transplantation for non-malignant diseases: however, the optimal conditioning to ensure stable engraftment has not been established. In this study, we retrospectively compared the impact of low-dose (1-6 Gy) irradiation and in vivo T-cell depletion on the clinical outcome of 523 patients with non-malignant disease who underwent a first allogeneic hematopoietic stem cell transplantation using fludarabine-based reduced-intensity conditioning. Use of low-dose irradiation, but not of anti-thymocyte globulin/anti-lymphocyte globulin, showed a beneficial effect on overall survival (adjusted hazard ratio: 0.56; 95% confidence interval: 0.35-0.91, P = 0.018). Furthermore, use of low-dose irradiation was strongly associated with lower transplant-related mortality (adjusted hazard ratio: 0.55; 95% confidence interval: 0.32-0.96, P = 0.034). The addition of low-dose irradiation to the conditioning regimen was beneficial, at least to the short-term clinical outcome. A large prospective study with long-term follow-up is now required to extend these findings and establish the optimal hematopoietic stem cell transplant conditioning for patients with at least some subgroups of non-malignant diseases.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: The role of local radiotherapy in the treatment of metastatic rhabdomyosarcoma is important. However, with peritoneal dissemination, the application of local therapy is challenging. Although there are few reports addressing the efficacy of the whole abdominopelvic irradiation to peritoneal disseminated rhabdomyosarcoma patients, no precise curse of treatment nor the follow up result is explained in paper nor in the text. CASE PRESENTATION: Six years old rhabdomyosarcoma boy with peritoneal dissemination was treated at our facility under COG D9803 protocol (vincristine, dactinomycin, and cyclophosphamide (VAC)). He underwent tumor resection on the 14th week according to the protocol. During surgery, the 2-cm residual tumor was completely resected, but in the pelvis, numerous nodules that were suspected as peritoneal disseminated tumors were observed. We administered 30 Gy/20fr whole abdominopelvic radiotherapy using volumetric modulated arc therapy (VMAT) technique and a 6 Gy sequential boost to pelvis after the surgery and completed the protocol treatment. During the course of treatment, the patient experienced G4 hematological toxicity and received multiple transfusions, particularly after whole abdominopelvic irradiation. He has achieved complete remission and is alive without evidence of recurrence and severe late adverse effect for 3 years. In terms of growth, his height and weight are within the average values for Japanese boys at the same age. CONCLUSION: By using the VMAT technique, a patient with peritoneal disseminated rhabdomyosarcoma can be treated, and a dose of 30 Gy to the whole abdominopelvis with concurrent chemotherapy may be tolerable.

Language：English Publishing type：Research paper (scientific journal)

Human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) are the leading causes of acute respiratory tract infection in children, and clinical manifestations of these virus infections are considered similar. To investigate the differences in clinical characteristics between HMPV and RSV infections in young children, we prospectively enrolled children ＜ 3 years old who required hospitalization with acute respiratory tract infection due to HMPV or RSV at 10 hospitals in Japan. We enrolled 48 children with HMPV infection and 141 with RSV infection. Patients with HMPV infection were older than those with RSV infection. High-grade fever was more frequently observed in patients with HMPV infection, whereas no significant differences in respiratory symptoms were apparent. Abnormal serum lactate dehydrogenase values and consolidation shadows on chest X-ray were more frequently observed in patients with HMPV infection. During hospitalization, nasal mucus suction was more frequently required in patients with RSV infection. On the other hand, β2-adrenergic agonists, corticosteroids, and leukotriene receptor antagonists were more frequently used in patients with HMPV infection. These findings suggest that HMPV and RSV infections show similar respiratory symptoms, but HMPV infection is more likely to lead to the development of pneumonia, at least among hospitalized young children.

BACKGROUND: In this study, we aimed to identify the gene abnormality responsible for pathogenicity in an individual with an undiagnosed neurodevelopmental disorder with megalencephaly, ventriculomegaly, hypoplastic corpus callosum, intellectual disability, polydactyly and neuroblastoma. We then explored the underlying molecular mechanism. METHODS: Trio-based, whole-exome sequencing was performed to identify disease-causing gene mutation. Biochemical and cell biological analyses were carried out to elucidate the pathophysiological significance of the identified gene mutation. RESULTS: We identified a heterozygous missense mutation (c.173C>T; p.Thr58Met) in the MYCN gene, at the Thr58 phosphorylation site essential for ubiquitination and subsequent MYCN degradation. The mutant MYCN (MYCN-T58M) was non-phosphorylatable at Thr58 and subsequently accumulated in cells and appeared to induce CCND1 and CCND2 expression in neuronal progenitor and stem cells in vitro. Overexpression of Mycn mimicking the p.Thr58Met mutation also promoted neuronal cell proliferation, and affected neuronal cell migration during corticogenesis in mouse embryos. CONCLUSIONS: We identified a de novo c.173C>T mutation in MYCN which leads to stabilisation and accumulation of the MYCN protein, leading to prolonged CCND1 and CCND2 expression. This may promote neurogenesis in the developing cerebral cortex, leading to megalencephaly. While loss-of-function mutations in MYCN are known to cause Feingold syndrome, this is the first report of a germline gain-of-function mutation in MYCN identified in a patient with a novel megalencephaly syndrome similar to, but distinct from, CCND2-related megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome. The data obtained here provide new insight into the critical role of MYCN in brain development, as well as the consequences of MYCN defects.
