Abstract

Present 3-D stereology techniques use fixed grid sampling where the sampling grid of test points is randomly placed in 3-D. In order to increase randomness of sampling, in this paper we propose random grid sampling scheme where grid sections are placed randomly over 2-D cross-sections. A random grid sampler has superior efficiency and accuracy compared with fixed grid sampling. Using MR head scans we demonstrate the use of random grid sampling in volumetry of structures in 3-D biomedical images.

Comparison of intracranial pressure measured simultaneously within the brain parenchyma and cerebral ventricles.

We report a 48-year-old man treated for acute subarachnoid hemorrhage (SAH) wherein intracranial pressure (ICP) was measured simultaneously within the ventricular cerebrospinal fluid (CSF) and the brain parenchyma (PAR). Single pressure waves within the continuous pressure signal were identified with determination of the single wave parameters pulse amplitude (i.e. pressure difference between diastolic minimum pressure and systolic maximum pressure), mean pressure (i.e. mean pressure from beginning to ending minimum diastolic minimum pressure), and latency (i.e. rise time from diastolic minimum pressure to systolic maximum pressure). A total of 218,589 CSF/PAR single pressure wave pairs were analyzed. For these CSF/PAR wave pairs the mean difference in pulse pressure amplitude was -0.13 mmHg [95% confidence interval (CI) -0.13 to -0.12 mmHg], mean difference in mean single wave pressure -0.71 mmHg (95% CI -0.74 to -0.68 mmHg), and mean difference in latency -0.01 seconds (95% CI -0.01 to -0.01 seconds). Hence, in this patient monitoring ICP within the ventricular CSF or brain parenchyma gave similar results. Moreover, the comparisons of single CSF/PAR wave pulse pressure amplitudes gave no evidence of a pressure gradient from brain parenchyma to the ventricular CSF in this patient.

Periventricular nodular heterotopia and Williams syndrome.

We report here on the first case of a child with bilateral periventricular nodular heterotopia (PNH) and Williams syndrome. Fluorescent in situ hybridization (FISH) analyses demonstrated a deletion of the elastin gene in the Williams syndrome critical region (WSCR). Further mapping by loss of heterozygosity analysis both by microsatellite marker and SNP profiling demonstrated a 1.5 Mb deletion beyond the telomeric end of the typical WSCR. No mutations were identified in the X-linked filamin-A gene (the most common cause of PNH). These findings suggest another dominant PNH disorder along chromosome 7q11.23.
