Major investments in highway or transit infrastructure often require a decade or more to move from planning to completion. Therefore, a solid understanding of California's future transportation infrastructure needs implies a critical evaluation of the projections of the state's total population, what this population will look like, where they will live and(More)
Ten members of a large family who showed manifestations of either von Hippel-Lindau disease or von Recklinghausen's neurofibromatosis were examined. Three of 10 members were found to have retinal angiomas which had not been present on fundus examination 3 years previously. These angiomas were associated with ocular and systemic signs of neurofibromatosis.(More)
Our mission is to lead in developing transportation data and information of high quality and to advance their effective use in both public and private transportation decisionmaking. Our vision for the future: Data and information of high quality will support every significant transportation policy decision, thus advancing the quality of life and the(More)
The increased use of axial imaging in various fields of medicine has led to an increased frequency of incidental findings, specifically incidental cancer lesions. Hence, as the use of multiparametric magnetic resonance imaging (MP-MRI) for prostate cancer detection, staging, and management becomes more widespread, the potential for additional incidental(More)
Unicentric Castleman disease (UCD) is a relatively rare lymphoproliferative disease, which commonly presents as a mediastinal mass and less frequently involves abdomen, pelvis, and retroperitoneum. We report a case of a 64-year-old man with newly diagnosed low-volume, Gleason 3 + 3 = 6 prostate adenocarcinoma, who in considering active surveillance versus(More)
PURPOSE Evaluate Gadoxetate Disodium enhanced dual-energy CT for visualization of perihilar cholangiocarcinoma by exploiting the hepatobiliary uptake of Gadoxetate Disodium and viewing images at the k-edge of gadolinium on the spectrum of simulated monoenergetic energies available with Dual Energy CT. MATERIAL AND METHODS In this prospective, IRB-approved(More)
The outcomes and costs of 6 different methods of motivating therapists to meet service delivery goals at a community mental health center for children and adolescents were evaluated over a 5-year period. The costs and cost-savings benefits of each motivational method were compared with each other and with two baselines. Four incentive interventions(More)
A 24-year-old woman had bilateral pendular nystagmus, foveal hypoplasia, 360-degree peripheral retinal rosettes, and hypoplastic ora serrata of nongenetic origin. Kinetic perimetry revealed a generalized constriction of the field. Flicker perimetry revealed general depression of the critical flicker frequencies in the entire field. A slight increase of the(More)
