Bone mineral density (BMD) was evaluated in the proximal femora (femoral neck, Ward's triangle, and greater trochanter) and lumbar spines of 25 black children and young adults with sickle cell anemia using dual-photon absorptiometry. Compared with normal subjects from the general population, the patients with sickle cell anemia exhibited lower bone mineral(More)
A hospital-based computer system was used to compare the inpatient costs of performing bilateral simultaneous sequential, staged, and unilateral total hip and knee arthroplasties. Bilateral simultaneous sequential total knee arthroplasty was 36% less costly than 2 unilateral total knee arthroplasties. Bilateral simultaneous sequential total hip arthroplasty(More)
The financial and medical records of 98 patients undergoing either primary total hip or total knee arthroplasty were analyzed to determine the inpatient cost of their surgery. Eleven patients were excluded, leaving a total of 87 patients available for analysis who underwent 50 primary total hip and 37 primary total knee arthroplasties. Ten separate cost(More)

Significant neurological research using liquid crystal thermography (LCT) has been performed; however, its acceptance as a practical and useful modality has been slow. Reviewing the method together with some of the most current research should help clarify its role and reveal its potential. This paper defines thermography, describes how infrared patterns(More)
Rupture of the urinary tract during pregnancy is uncommonly reported. Nevertheless, pregnancy-induced changes in the urinary tract predispose to tears and leaks in the renal parenchyma or collecting system. Pyelonephritis, painful overdistension, and rupture are consequences of the effects of pregnancy on the urinary tract. Thirteen cases of urinary tract(More)
African Americans have a higher prevalence of elevated blood pressure and a higher prevalence of increased intraocular pressure (IOP). The blood pressure of African Americans has been found to be related to skin color. This study evaluated whether IOP was related to skin color. We measured IOP using a Tonopen and skin darkness using a spectrocolorimeter in(More)
Algorithms for sensor deployment and adaptive sampling form the basis for multisensor fusion of spatio-temporal data from a wireless environmental network of deployed sensors. Derivation of sampling algorithms based on parametric methods are described. These algorithms form the basis for deployment of an array of wireless CTD (conductivity, temperature,(More)
