A meta-analysis of six double-blinded clinical trials was undertaken to identify risk factors associated with bacteriologic outcome in 3,108 women with acute cystitis. Eleven antibiotic regimens were used, including ciprofloxacin, ofloxacin, norfloxacin, trimethoprim-sulfamethoxazole, and nitrofurantoin. Entry criteria for all studies were identical. Among 2,409 patients who were defined to be ...

Purpose: To review the occurrence of macular retinal folds following retinal detachment surgery. Method: Review of the literature. Results: Macular folds have been reported in up to 3% of cases postoperatively. Risk factors are tamponading gas bubble, large exoplants, detachments with bullous configuration or running through the fovea, and incomplete drainage of subretinal fluid. Preventive mea...

OBJECTIVE Twin studies suggest that heritability of moderate-severe bronchopulmonary dysplasia (BPD) is 53% to 79%, we conducted a genome-wide association study (GWAS) to identify genetic variants associated with the risk for BPD. METHODS The discovery GWAS was completed on 1726 very low birth weight infants (gestational age = 25(0)-29(6/7) weeks) who had a minimum of 3 days of intermittent p...

It is proved in this note that all Hurwitz polynomials of ordernot less than n form two simply connected Bore1 cones in the polynomialparameter space. Based on this result, edge theoremsfor Hurwitz sta-bility of general polyhedrons of polynomials and boundary theorems forHurwitz stability of compact sets of polynomials are obtained. Both casesof families of polynomials w...

This paper deals with Exploratory Procedures for Computer Vision. The assumptions are that we have a mobile camera system with controllable focus, close/open aperture, and ability of recording its position, orientation and movement. Furthermore we assume an unknown and unstructured environment. For our analysis we consider two types of illumination sources: the point source and the extended sky...

Published by the IEEE Computer Society 0018-9162/10/$26.00 © 2010 IEEE In the past, developers used additional capacity to develop superscalar CPUs with replicated execution units and deep pipelines to exploit instruction-level parallelism. However, they only harvested about 25 percent of the additional chip space that became available per year by adding new architectural features.2 Moreover, t...

Spur cell anemia is a hemolytic anemia seen in severe alcoholic cirrhosis that is characterized by unusual morphology and a decreased ratio of phospholipids to cholesterol in the erythrocyte membrane. We hypothesized that defective phospholipid repair may contribute to the red blood cell (RBC) phospholipid abnormalities of spur cell anemia. Therefore, we compared RBCs from normal control subjec...

PURPOSE To characterize the optical coherence tomography angiography (OCTA) appearance of the perifoveal macular microvasculature in visually asymptomatic patients with sickle cell disease, and to compare these findings with those of fluorescein angiography (FA). DESIGN Retrospective observational case series. METHODS Eighteen eyes of 9 consecutive patients with a median age of 41 years (ra...

We examine color constancy algorithms based on finite-dimensional linear models of surface reflectance and illumination from a computational point of view. It is shown that, within finite dimensional models, formulation and solution of color constancy are determined by the choice of basis functions, the number of spectral receptors and the spatial constraints. We analyze some algorithms with ex...
