Neurological deterioration in the tethered cord syndrome has been postulated to result from a compromise of blood flow in the distal spinal cord. In order to evaluate vascular perfusion in human subjects, a new technique of laser-Doppler flowmetry was used to monitor continuously the microcirculation of the distal spinal cord during surgery for tethered(More)
The long-term outcome of 75 children who underwent methyl methacrylate cranioplasty over a 15-year period is presented. Forty-two patients underwent cranioplasty for posttraumatic skull defects and 33 for nontraumatic causes. Within 8 years following initial cranioplasty procedure, a total of 17 (23%) complications occurred. Several factors correlated with(More)
Within 3 months, a 13-year-old girl had two thoracotomies performed for resection of pulmonary primary and metastatic malignant fibrous histiocytoma (MFH). Seven months following the second operation, a right frontal cerebral metastasis was diagnosed as responsible for the sudden onset of a left hemiparesis. Although she recovered from the craniotomy, and(More)
Congenital inclusion cysts of the subgaleal space in 23 white children are reported. Twenty-two cysts were dermoid and one was epidermoid in nature. The lesions were extracranial and had no intracranial extension. Their location in the subgaleal space was median or paramedian. Their clinical, radiologic, biochemical, and histologic characteristics are(More)
We study the response of magnetic nanoparticle suspensions (ferrofluids) to uniform rotating magnetic fields generated by a two-pole three-phase magnetic induction motor stator winding. Measurements of the torque required to rotate a polycarbonate spindle submerged in ferrofluid subjected to co-rotating and counter-rotating fields yield experimental(More)
Five patients with typical cervical myeloradiculopathy caused by focal cervical spinal stenosis are presented. Dorsal intrusions into the spinal canal by hypertrophied apophyseal joints and thickened laminae resulted in cord and nerve root compression. Minor spondylotic changes were present in the floor of the spinal canal. Laminar decompression with(More)
The optimal management of patients with myelomeningocele and hydrocephalus is facilitated by a constant review of the patients with the aid of the sonogram and CT scan. Six infants treated with simultaneous shunt placement and myelomeningocele repair were compared with six other neonates treated with conventional sequential myelomeningocele repairs(More)
Using a data set of 1217 patients with multiple myeloma enrolled in Total Therapies, we have examined the impact of novel therapies on molecular and risk subgroups and the clinical value of molecular classification. Bortezomib significantly improved the progression-free survival (PFS) and overall survival (OS) of the MMSET (MS) subgroup. Thalidomide and(More)
Measurements of magnetic-field-induced torque in applied uniform rotating magnetic fields are presented and compared to theoretical analyses for water-and oil-based ferrof-luids. These experiments measure the viscous torque on the inner wall of a stationary hollow polycarbonate spindle that is completely filled with ferrofluid and attached to a viscometer(More)
The authors report five patients with spinal stenosis who had a total myelographic block at the level of the obliterated subarachnoid space. Arachnoiditis had not been considered as a primary diagnosis until laminectomy revealed a non-pulsating, thickened dural sac that conformed to the internal configuration of the involved spinal canal. Two patients had(More)
