Two sisters, aged 6 and 2 1/2 years, presented with macrocephaly and delayed motor development and were found on computerized tomography to have bilateral arachnoid cysts of the sylvian region. Cystoperitoneal shunting of the larger cysts resulted in considerable neurological improvement in both children. Subsequent screening of the patients' urine for organic acids showed that the two sisters ...

The behavior of complex interfacial systems is central to an ever-increasing number of applications. Vibrational sum frequency (VSF) spectroscopy is a powerful technique for obtaining surface specific structural information. The coherent nature of VSF that provides surface specificity, however, also creates difficulty in spectral interpretation especially as the system complexity increases. Com...

Glutaric aciduria type 1 (GA1) is an autosomal recessive neurometabolic disorder caused by mutations in the glutaryl-CoA dehydrogenase gene (GCDH), leading to an accumulation and high excretion of glutaric acid and 3-hydroxyglutaric acid. Considerable variation in severity of the clinical phenotype is observed with no correlation to the genotype. We report here for the first time on expression ...

BACKGROUND Glutaric Aciduria type 1 (GA1) is a metabolic inborn error and is characterized by increasing excursion of glutaric acid and its derivates, presented in microcephaly and dystonia. The disease is resulted from mutational inactivation in the GCDH gene encoding the glutaryl-CoA dehydrogenase. The defective enzyme causes the accumulation of an excessive level of intermediate breakdown pr...

A one-year-old girl visited the hospital due to limb torsion and developmental regression for one month after hand, foot and mouth disease. At the age of 11 months, she visited a local hospital due to fever for 5 days and skin rash with frequent convulsions for 2 days and was diagnosed with severe hand, foot and mouth disease, viral encephalitis, and status epilepticus. Brain MRI revealed symme...
