Epileptic encephalopathies are a devastating group of severe childhood epilepsy disorders for which the cause is often unknown. Here we report a screen for de novo mutations in patients with two classical epileptic encephalopathies: infantile spasms (n = 149) and Lennox-Gastaut syndrome (n = 115). We sequenced the exomes of 264 probands, and their parents,(More)
Trypanolytic variants in APOL1, which encodes apolipoprotein L1, associate with kidney disease in African Americans, but whether APOL1-associated glomerular disease has a distinct clinical phenotype is unknown. Here we determined APOL1 genotypes for 271 African American cases, 168 European American cases, and 939 control subjects. In a recessive model,(More)
OBJECTIVE To demonstrate the safety and effectiveness of responsive stimulation at the seizure focus as an adjunctive therapy to reduce the frequency of seizures in adults with medically intractable partial onset seizures arising from one or two seizure foci. METHODS Randomized multicenter double-blinded controlled trial of responsive focal cortical(More)
OBJECTIVES To identify the neurologic complications of critical medical illnesses, and to assess their effect on mortality rates and on medical ICU and hospital lengths of stay. DESIGN Prospective clinical evaluation of all medical ICU admissions for 2 yrs. SETTING A 14-bed, general medical intensive and coronary care unit in a large university(More)
The pharmacokinetics and dosimetry of 86Y-DOTA0-d-Phe1-Tyr3-octreotide (86Y-SMT487) were evaluated in a phase I positron emission tomography (PET) study of 24 patients with somatostatin receptor-positive neuroendocrine tumours. The effect of amino acid (AA) co-infusion on renal and tumour uptake was assessed in a cross-over randomised setting. Five(More)
Epithelioid hemangioendothelioma is an unusual vascular neoplasm with prominent cytoplasmic vacuolization representing primitive lumen formation. A case is presented of this unique vascular neoplasm in a woman with a seizure disorder who had cardiac, hepatic, and recurrent nervous system lesions. To our knowledge, this is the third known case of(More)
Clinical observations are presented on the sensory effects of lesions of different afferent pathways of the spinal cord, correlated whenever possible with histological evidence of the location and extent of the lesions. They are based on personal cases and on significant cases in the literature, including posterior column section, other causes of damage to(More)
The course, location and relations of the corticospinal tracts within the spinal cord of man are demonstrated on the basis of cases with lesions above the spinal cord restricted to the corticospinal tracts, of motor neuron disease, and of anterolateral cordotomies; control cases were of normal spinal cords. The following features of the lateral(More)
