OBJECTIVE Ketogenic diets tend to cause trace mineral deficiencies. Ketonformula is a foumula for a ketogenic diet developed by Meiji Co Ltd in Japan. No reports are available on the trace mineral deficiencies associated with a use of Ketonformula. METHODS We monitored the serum levels of selenium, zinc and copper as well as the amount of the daily intake(More)
OBJECTIVE Recently, de novo mutations in GRIN1 have been identified in patients with nonsyndromic intellectual disability and epileptic encephalopathy. Whole exome sequencing (WES) analysis of patients with genetically unsolved epileptic encephalopathies identified four patients with GRIN1 mutations, allowing us to investigate the phenotypic spectrum of(More)
Toothbrushing-induced seizures are rare reflex seizures triggered by the brushing of one's own teeth. We encountered an 11-year-old girl with severe mental retardation, hypotonic cerebral palsy and epilepsy who presented with toothbrushing-induced seizures. She had had spontaneous brief tonic seizures several times a day since the age of 1 year and 2 months(More)
BACKGROUND Disorders of oxidative phosphorylation (OXPHOS) cause an increase in the NADH/NAD(+) ratio, which impairs the glycolysis pathway. Treatment with pyruvate is expected to decrease the ratio and thereby restore glycolysis. There are some case reports on the efficacy of pyruvate treatment for mitochondrial diseases. However, few of these reports(More)
Grisel syndrome is a non-traumatic atlantoaxial subluxation and a rare complication of any inflammatory condition of the upper neck and otolaryngological procedures. Delayed diagnosis causes neurological impairment, ranging from radiculopathy to paralysis and death. Kawasaki disease is a very frequent and important acute febrile vasculitis of childhood that(More)
BACKGROUND Valproate-induced Fanconi syndrome is a rare adverse effect of valproate. Severely disabled patients who require tube feeding are reported to be susceptible to valproate-induced Fanconi syndrome. Although most patients with valproate-induced Fanconi syndrome are asymptomatic and detected incidentally with findings such as hypophosphatemia,(More)
We introduced a low glycemic index treatment using Japanese ethnic foods to a 13-year-old girl with Lennox-Gastaut syndrome caused by tuberous sclerosis complex. She had previously refused the modified Atkins diet within 2 weeks of diet treatment because of its restrictiveness. The low glycemic index treatment was implemented by limiting the daily(More)
Cutis laxa (CL) syndromes are connective tissue disorders characterized by redundant, sagging, inelastic and wrinkled skin, with organ involvement. Here, we describe a patient with ALDH18A1-related CL who developed cyclic vomiting. The patient was a 12-year-old boy who presented with poor postnatal growth, hypotonia, short stature, joint hyperlaxity,(More)
OBJECTIVE Severe muscle hypertonia in patients with the mixed type of tetraplegia may be associated with significant deterioration in the quality of life of the patients. Intermittent use of oral muscle relaxant drugs, for example, Tizanidine (Ternelin), which is a fast-acting muscle relaxant, can provide relief from the severe hypertonia in these patients,(More)
Creatine transporter deficiency (CRTR-D) is an X-linked disorder characterized by hypotonia, developmental delay, and seizures. We report the third Japanese family with CRTR-D. The proband was an 8-year-old boy who presented with hypotonia, severe intellectual disability and two episodes of seizures associated with/without fever. Among 7 siblings (4 males,(More)
