Interleukin-1 (IL-1) is markedly overexpressed in Alzheimer's disease. We found the IL-1A 2,2 genotype in 12.9% of 232 neuropathologically confirmed Alzheimer's disease patients and 6.6% of 167 controls from four centers in the United Kingdom and United States (odds ratio, 3.0; controlled for age and for ApoE [apolipoprotein E] genotype). Homozygosity for(More)
BACKGROUND The role of chemotherapy in the treatment of patients with primary central nervous system lymphoma (PCL) remains unclear, with no randomized trials available to aid in the interpretation of the current data. The Medical Research Council therefore conducted the current randomized trial to assess the impact on survival of postradiotherapy(More)
Astroblastoma is a rare type of glial tumor, usually occurring in older children and young adults. It has a distinctive histological appearance that is characterized by a radiating arrangement of tumor cells that form perivascular pseudorosettes. The authors report only the second case of astroblastoma presenting in congenital form. Following subtotal tumor(More)
BACKGROUND AND PURPOSE White matter (WM) hyperintensities on MRI or leukoaraiosis is characteristic of stroke syndromes. Increased MRI signals in the anterior temporal pole are suggested to be diagnostic for cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), with 90% sensitivity and 100% specificity. The(More)
The authors report two cases of Teflon-induced granuloma occurring as a result of microvascular decompression using Teflon wool for the treatment of trigeminal neuralgia (TN). Teflon, which is used to separate a compressing vessel from the root entry zone (REZ) of the trigeminal nerve at the brainstem, is presumed to be an inert material. In the two cases(More)
Following unilateral sciatic nerve crush in mice, changes in the neurofilament content of neuronal perikarya were studied, using a monoclonal antibody to neurofilament protein (RT97). In the spinal cord, anterior horn motor neurones, normally unstained, showed a positive staining reaction with immunoperoxidase on the operated side. This reaction was short(More)
Diffuse axonal injury (DAI) is an important cause of morbidity and mortality after traumatic brain injury (TBI), and its severity is therefore a major determinant of outcome. There have been suggestions that the extent of DAI may be reflected in quantitative measures of cerebral function, including the electroencephalogram (EEG) and brain-stem auditory(More)
Several hereditary small vessel diseases (SVDs) of the brain have been reported in recent years. In 1977, Sourander and Wålinder described hereditary multi-infarct dementia (MID) in a Swedish family. In the same year, Stevens and colleagues reported chronic familial vascular encephalopathy in an English family bearing a similar phenotype. These disorders(More)
The authors report the case of a 45-year-old man who presented with a short duration of a painful ophthalmoparesis. Initial magnetic resonance imaging revealed an extraaxial petroclival mass characteristic of an epidermoid cyst, with the exception of a contiguous contrast-enhancing lobule. A subtotal resection was performed with the histopathological(More)
Pituitary carcinoma with metastatic endocrine secreting tissue is rare. Eight cases of malignant, growth hormone-secreting tumours, all metastatic within the central nervous system have been previously described. Complete surgical resection was not possible and the patients died within 4 years of presentation with distant spread. Here we describe the first(More)
