Between 1972 and 1989, the incidence of viridans streptococcal bacteremia at the University of Texas M. D. Anderson Cancer Center in Houston increased from one case per 10,000 admissions to 47 cases per 10,000 admissions (P less than .0001). A shock syndrome characterized by hypotension, rash, palmar desquamation, adult respiratory distress syndrome, and(More)
A retrospective review of the transvaginal sonograms of 50 women with laparoscopically confirmed ectopic pregnancy was performed to determine whether certain sonographic findings can be detected to confirm the diagnosis. Forty-seven of the 50 pregnancies were tubal. A tubal ring (a 1-3-cm mass consisting of a 2-4-mm concentric, echogenic rim of tissue(More)
Diverticula of the female urethra can be difficult to diagnose. Invasive contrast studies (voiding cystourethrography or double-balloon urethrography) or urethroscopy are frequently required for definitive diagnosis. Although transabdominal sonography has been able to visualize large diverticula, this technique has not proved useful in routine screening. In(More)
Accurate preoperative staging is important for proper selection of patients for radical retropubic prostatectomy. Preoperative staging by digital rectal examination, transrectal ultrasound, magnetic resonance imaging (MRI), Gleason grade and prostate specific antigen was compared to pathological stage for 25 patients who underwent radical retropubic(More)
An ergonomically simple prototype workstation with two 900×1,100-pixel monitors capable of displaying eight full-resolution computed tomography (CT) images in 0.2 seconds, was compared with film for interpretation of computed tomographic images of the chest and abdomen. The hardware platform for this workstation cost less than $11,500 in 1993. A(More)
RATIONALE AND OBJECTIVES A radiologist practicing remote ultrasound occasionally needs to review a case in real time before releasing the patient. The authors conducted a pilot study to evaluate one solution in which the radiologist views real-time images on a video monitor while conversing with the technologist via a headset telephone. METHODS Two(More)
A series of 25 patients with biopsy proven adenocarcinoma of the prostate underwent preoperative staging evaluation with a digital rectal examination, endorectal ultrasound, and body coil magnetic resonance imaging (MRI) before their radical retropubic prostatectomy. The sensitivity and specificity of the digital rectal examination for the detection of(More)
Hemispheric specialization for linguistic material was compared for normal and dyslexic subjects under dichotic listening (Experiment 1) and hemi-retinal presentation (Experiment 2) conditions. In both experiments, group data indicated that dyslexic subjects were, overall, less accurate in their performance than normals but that both groups showed similar(More)
In a prospective study, 32 consecutive patients underwent endovaginal pelvic scanning in the first post-operative week following hysterectomy. Twenty-four attended for a further scan at clinical follow up. Vaginal vault fluid collections were identified in 19 women (59%) on the first post-operative scan. Fifteen of the 19 with collections had no significant(More)
