BACKGROUND Genomic imbalances constitute a major cause of congenital and developmental abnormalities. GLUT1 deficiency syndrome is caused by various de novo mutations in the facilitated human glucose transporter 1 gene (1p34.2) and patients with this syndrome have been diagnosed with hypoglycorrhachia, mental and developmental delay, microcephaly and(More)
Twenty-four Turkish children who had had neonatal tetanus were evaluated by means of physical and neurological examinations and psychometric tests at four to 15 years of age. Enuresis, mental retardation and growth retardation were frequent findings. The prevention of neonatal tetanus is important not only because of the high mortality rate but also because(More)
A total of 72 EEGs from 57 patients with SSPE were studied. The EEG studies in SSPE revealed periodic high amplitude complexes in all except one. Besides periodic complexes, we found several atypical EEG findings including frontal rhythmic delta activity in intervals between periodic complexes, electrodecremental periods following EEG complexes, diffuse(More)
We treated 22 patients with subacute sclerosing panencephalitis (SSPE) with intraventricular alpha-interferon (IFN) and inosiplex PO and followed them for 2 to 54 months. Three deaths occurred. Clinical improvement, demonstrated by decreasing scores on the Neurological Disability Index, occurred in 11/22 (50%); five patients became stable, and the(More)
Subacute sclerosing panencephalitis (SSPE) is associated with inflammatory infiltration, neuronal loss, and demyelination. The pathogenesis of these changes is unclear. We examined DNA fragmentation and Bcl-2 expression in brain biopsies of nineteen SSPE patients to investigate the role of apoptosis in tissue damage. DNA fragmentation was present in(More)
The pattern of inflammatory infiltration was studied in the frontal brain biopsies of 28 cases with subacute sclerosing panencephalitis (SSPE) by immunohistochemistry. Lymphocytic infiltration and gliosis were common pathologic findings. CD4+ T lymphocytes were often observed in perivascular areas and CD8+ lymphocytes in the parenchyma. B lymphocytes were(More)
PURPOSE To define various cranial MR appearances in Wilson's disease (WD). MATERIAL AND METHODS MR examinations of 30 patients (9-44 years old) with WD were retrospectively reviewed. Six patients were asymptomatic siblings. Three other patients had isolated hepatic involvement, one with no symptoms. The remaining 21 patients had neurological involvement,(More)
The neurologic manifestations of patients with phenylketonuria treated at different ages are illustrated in this series of 146 cases, including 9 sib pairs. In addition to well-known findings such as mental retardation, autistic features, microcephaly, and tremor, motor retardation was common and responded promptly to dietary treatment. Hypotonia and(More)
Thirty-four MRI studies of 26 patients with subacute sclerosing panencephalitis are reported. Lesions of high signal intensity on T2-weighted images are the most common finding; they frequently involve the periventricular or subcortical white matter. Lesions tend to start in the cortex-subcortical white matter and progress with periventricular white matter(More)
