RESUMEN
Proper nutritional management is important for the growth and development of children with motor or intellectual disabilities; however, few studies have investigated the nutrient intake of children with disabilities. This study aimed to investigate the nutrient intake and food groups that are the main sources of nutrients for children with disabilities. This cross-sectional observational study included twenty-five children (mean age, 11â 8 years) from five hospitals in Japan. Using a 3-d weighed dietary record, we estimated the daily nutrient intake and food and beverage sources that contributed to nutrient intake. The mean values of calcium, magnesium, iron, vitamin A, thiamine, riboflavin, and vitamin C intake were below the recommended dietary allowance, and those of dietary fiber and potassium were below the levels recommended by the Tentative Dietary Goal for Preventing Lifestyle-related Diseases (DG). In contrast, the mean intake values of fat, saturated fatty acids, and sodium were above the DG levels. Dairy products, meat, vegetables, and cereals were found to be the major contributors of nutrients. Increased intake of vegetables may help alleviate insufficient micronutrient intake in children with disabilities.

UNLABELLED: Glucose transporter 1 deficiency syndrome (GLUT1DS) is an autosomal dominant disorder of brain energy metabolism caused by impaired GLUT1-mediated glucose transport across the blood-brain barrier. Although the clinical spectrum of this disorder is expanding rapidly, the growth patterns and endocrine status of these patients are not well known. We report the case of a boy aged 12 years and 7 months who has GLUT1DS complicated by growth failure. His failure to grow had progressed since birth, and his body height was 125 cm (-3.6 SDS). Growth hormone stimulation tests showed severe growth hormone deficiency (GHD), and we initiated GH replacement therapy. After 2 years of treatment, the boy's growth rate recovered from 1.7 cm/year before treatment, to 7.5 cm/year and 4.3 cm/year after treatment with no adverse effects. We speculate that GHD is a possible complication of GLUT1DS and discuss the underlying causative mechanism. CONCLUSION: GHD may be a possible complication of GLUT1DS.

De novo GNAO1 variants have been found in four patients including three patients with Ohtahara syndrome and one patient with childhood epilepsy. In addition, two patients showed involuntary movements, suggesting that GNAO1 variants can cause various neurological phenotypes. Here we report an additional four patients with de novo missense GNAO1 variants, one of which was identical to that of the previously reported. All the three novel variants were predicted to impair Gαo function by structural evaluation. Two patients showed early-onset epileptic encephalopathy, presenting with migrating or multifocal partial seizures in their clinical course, but the remaining two patients showed no or a few seizures. All the four patients showed severe intellectual disability, motor developmental delay, and involuntary movements. Progressive cerebral atrophy and thin corpus callosum were common features in brain images. Our study demonstrated that GNAO1 variants can cause involuntary movements and severe developmental delay with/without seizures, including various types of early-onset epileptic encephalopathy.
