To determine if infection with herpes simplex virus (HSV) type 2 is associated with human immunodeficiency virus (HIV) type 1 infection among patients attending sexually transmitted diseases clinics, a case-control study was done on coded sera from 179 HIV-1-infected patients and 367 age-, race-, and gender-matched HIV-1-seronegative patients. Although only(More)
PURPOSE To determine the relative time required for a technologist to perform a computed tomographic (CT) examination in a "filmless" versus a film-based environment. MATERIALS AND METHODS Time-motion studies were performed in 204 consecutive CT examinations. Images from 96 examinations were electronically transferred to a picture archiving and(More)
Highlights ► We modify OPLS force field to describe mixture. ► We calculated Gibbs free energy by thermodynamic integration method. ► We investigate the stability of mixture. ► We predict mutual solubility by double tangent method. The liquid–liquid equilibria for low pH aqueous acid solution + tri-octylamine (or tri-butylphosphate) + 1-decane and the(More)
BACKGROUND AND OBJECTIVE Because patients with diabetes mellitus may visit their primary care physician regularly but not their ophthalmologist, a retinal risk assessment in the primary care setting could improve the screening rate for diabetic retinopathy. An imaging system for use in the primary care setting to identify diabetic retinopathy requiring(More)
A serologic survey of 4863 patients attending two inner-city sexually transmitted disease clinics was conducted in 1988 1 year after an initial survey to reassess the prevalence and associated risk factors for human immunodeficiency virus (HIV) infection. The HIV seroprevalence rates had not changed significantly (5.2% in 1987, 4.9% in 1988), and remained(More)
BACKGROUND The prevalence of erectile dysfunction (ED) among patients with end-stage renal disease (ESRD) is not known. METHODS A cross-sectional study was conducted to determine the prevalence of ED among a community-based hemodialysis (HD) population using a two-stage cluster random sampling design. The presence and severity of ED were assessed among(More)
Knowing which method parameters may be mutated during a method's executionis useful for many software engineering tasks. We present an approach todiscovering parameter reference immutability, in which several lightweight, scalable analyses are combined in stages, with each stage refining the overall result. The resulting analysis is scalable and combines(More)
Since January 25, 1988, the Baltimore City Health Department has offered routine, confidential, human immunodeficiency virus (HIV) testing to clients of the city's two sexually transmitted disease (STD) clinics. During the first 11 months of the program, testing was offered at 20,843 patient visits and was accepted at 15,181 (73%) of these; 612 (4%)(More)
