PURPOSE To evaluate single-agent activity of bevacizumab in patients with recurrent glioblastoma. PATIENTS AND METHODS Patients with recurrent glioblastoma were treated with bevacizumab 10 mg/kg every 2 weeks. After tumor progression, patients were immediately treated with bevacizumab in combination with irinotecan 340 mg/m(2) or 125 mg/m(2) every 2(More)
OBJECT In the course of their lives most patients with von Hippel-Lindau (VHL) disease require treatment for several symptom-producing hemangioblastomas of the cerebellum, brainstem, or spinal cord. However, many tumors never produce symptoms and do not require treatment. Detection at an early stage of lesions that will later produce symptoms and ultimately(More)
BACKGROUND Autoinflammatory diseases manifest inflammation without evidence of infection, high-titer autoantibodies, or autoreactive T cells. We report a disorder caused by mutations of IL1RN, which encodes the interleukin-1-receptor antagonist, with prominent involvement of skin and bone. METHODS We studied nine children from six families who had(More)
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder characterized by cortical and spinal motor neuron dysfunction. Routine magnetic resonance imaging (MRI) studies have previously shown hypointense signal in the motor cortex on T(2)-weighted images in some ALS patients, however, the cause of this finding is unknown. To(More)
von Hippel-Lindau disease (VHL) is an autosomal-dominant neoplasia syndrome that is the result of a germline mutation of the VHL tumor suppressor gene on the short arm of chromosome 3. Patients with VHL are predisposed to develop lesions of the central nervous system and viscera. Central nervous system lesions include hemangioblastomas (the most common(More)
In the mustached bat, Pteronotus parnellii, neurons in the primary auditory cortex (AI) have been thought to respond primarily to single frequencies, as in other mammals. However, neurons in the Doppler-shifted constant-frequency (DSCF) area, a part of the mustached bat's AI that contains an overrepresentation of the prominent CF2 component of the biosonar(More)
BACKGROUND AND PURPOSE Fabry disease is a multisystem X-linked disorder characterized clinically by angiokeratoma, corneal and lenticular abnormalities, acroparesthesia, and renal and cardiac dysfunction and stroke. We sought to describe novel neuroimaging characteristics of Fabry disease. METHODS Neuroradiologic records of 104 hemizygous patients with(More)
Neurocysticercosis is responsible for increased rates of seizures and epilepsy in endemic regions. The most common form of the disease, chronic calcific neurocysticercosis, is the end result of the host's inflammatory response to the larval cysticercus of Taenia solium. There is increasing evidence indicating that calcific cysticercosis is not clinically(More)
