We assessed the importance of Streptococcus pneumoniae and immunologic response to 14-valent pneumococcal vaccine in a randomized (saline placebo or vaccine) double-blind pilot study involving 103 patients with chronic obstructive pulmonary disease (COPD). Antibody titers, the flora of the sputum, respiratory infections or pneumonias, and deaths were(More)
BACKGROUND CONTEXT Degenerative changes in the lumbar spine may result in a loss of spinal stability and subluxation of one vertebra relative to another. Cadaveric studies and clinical case series have suggested that listhesis may be much more common in African Americans than in whites. PURPOSE To determine the prevalence of lumbar spine listhesis(More)
STUDY DESIGN A study of agreement between different measures of kyphosis, a clinical standing measure (Debrunner kyphometer; Protek AG, Bern, Switzerland) versus a supine radiologic measure (Cobb angle). OBJECTIVES To determine whether a supine radiologic measure of kyphosis in older women is a reasonable estimate of clinical kyphosis determined in the(More)
Pulmonary blood volume was determined by the radiocardiographic technique in 49 patients coming to cardiac catheterization. Since this method has not been directly compared with the more commonly used double injection of dye. 25 comparisons were carried out in 13 patients of the series. Agreement was good over a range of 4.5-21.1 heart cycles since there(More)
An analysis of the patterns and amplitudes of the precordial movements is presented. Normal young adult subjects had three types of patterns. Type I occurred in 78 per cent, type II in 14 per cent, and type III in 8 per cent of the subjects studied. The variations of the kinetocardiogram from apex cardiograms and pneumocardiograms are discussed.
Pulmonary blood volume (PBV), flow, and pressures were measured in 15 cardiopulmonary normal subjects, while supine and at 60 degrees head-up passive tilt. PBV, cardiac index (CI), right ventricular diastolic volume (VDVR), and mean pulmonary arterial (Ppa), venous (Pv), and mean right atrial (Pra) pressures all decreased during the first 4 min of tilting,(More)
