This longitudinal study describes the growth of syntactic abilities and vocabulary size in nine children with unilateral antepartum or perinatal brain injury. Five children with left hemisphere damage (LHD) and four with right hemisphere damage (RHD), ages 15 to 48 months, were evaluated on three or more occasions. Language samples generated from(More)
MR imaging was performed on three formaldehyde-fixed brainstem specimens that were sectioned in the axial plane and myelin stained. The histologic sections were used to identify and label the structures demonstrated on short TR/TE axial MR images. Fiber tracts and nuclei that cannot be resolved on in vivo scans were well delineated by in vitro MR. Improved(More)
The pattern and the focal electroretinogram (ERG) are both non-invasive, electrophysiological responses recorded from circumscribed retinal areas and are most easily recorded from the macula. This paper describes how our department has incorporated these tests into our clinical protocol, shows how the recording technique and the method of electrode(More)
Fifteen children, 8 months of age or older, from a neonatal follow-up program underwent magnetic resonance imaging and neurologic, cognitive, and language evaluations. Magnetic resonance imaging findings in all children included increased white matter signal on T2-weighted images and ventricular enlargement adjacent to regions of abnormal white matter. The(More)
Heuristics describe the multiple small steps required for successful surgery, which are often taken for granted, enabling key manoeuvres, their correct order and their timely performance. Successful hemithyroidectomy is dependent on correct siting of the incision; tension to allow elevation of sub-platysmal flaps without damaging anterior jugular veins;(More)
Leptomeningeal (LM) cancer spread from either a primary brain tumor or a systemic cancer is rapidly fatal. Current therapies are ineffective and highly toxic to normal nervous system tissues. A xenograft model of LM neoplasia in nude rats using a diversity of tumor cell types was established in order to evaluate new treatment strategies and to study the(More)
Fast low-angle multiecho (FLAME) imaging uses partial flip angles of less than 90 degrees with 180 degrees radiofrequency refocusing pulses. The partial flip angle permits imaging with shorter repetition time (TR) values on the order of 750-1,000 ms for 30 degrees angles with image contrast characteristics identical to those obtained with conventional(More)
1.5 Tesla MRI examinations were evaluated for aqueductal configuration, hydrocephalus and flow-related signal void in 70 patients with juxtaaqueductal pathology and in 20 normal controls. In the 70 cases with pathology, the aqueduct was obliterated or distorted in 34, dilated in 3, normal in 29 and not evaluable in 4. A definite flow-related signal void(More)
