Mesenteric panniculitis is a rare entity of benign features that affects the intestinal mesenteric fat tissue and can progress in different ways, from spontaneous resolution to fibrosis. The etiology is still uncertain, probably caused by trauma, infection or surgery. We report a case of a 64-year-old male patient who suddenly began with abdominal pain and leukocytosis. Diagnosis of mesenteric ...

The authors describe a low-cost CT scanner integrated with a radiotherapy simulator and designed for treatment planning. The standard rotational gantry and x-ray tube of the simulator are used with a multiwire xenon lonization chamber and simple current-proportional readout system to measure patient attenuation, avoiding problems associated with diagnostic CT scanners in treatment planning. Al...

We introduce BrainPrint, a compact and discriminative representation of brain morphology. BrainPrint captures shape information of an ensemble of cortical and subcortical structures by solving the eigenvalue problem of the 2D and 3D Laplace-Beltrami operator on triangular (boundary) and tetrahedral (volumetric) meshes. This discriminative characterization enables new ways to study the similarit...

We recovered Bartonella quintana DNA from dental pulp of a domestic cat. This study, the first to detect B. quintana in a nonhuman mammal, changes our understanding of the epidemiology of this infection and proposes that cats may be an emerging source of human infection.

INTRODUCTION This report describes a 24 year old man with a posterior fossa medulloblastoma. His postoperative course was instructive because of the discrepancies that developed between the CT scan interpretations and the operative findings. His case history wi...

We address the asymptotic and approximate distributions of a large class of test statistics with quadratic forms used in association studies. The statistics of interest take the general form D=X(T)A X, where A is a general similarity matrix which may or may not be positive semi-definite, and X follows the multivariate normal distribution with mean mu and variance matrix Sigma, where Sigma may o...

A virtual-reality setup was used to investigate the relationship between perceived body ownership and subjective anxiety, as assessed by an anxiety inventory (SA-I). A pilot study confirmed that synchrony between the participant's real hand movements and the movements of a virtual effector induced perceived ownership illusions. The illusions were comparable for virtual human hands and virtual c...
