Nontuberculous mycobacterium (NTM) is an infrequent cause of prosthetic knee joint infections. Simultaneous infection with different NTM species in a prosthetic knee joint has not been previously reported. A case of prosthetic knee joint infection caused by Mycobacterium abscessus and M. fortuitum is described in this report. The patient was successfully treated with adequate antibiotics and su...

Patient-prosthetic aortic valve mismatch (PPM) is a clinical diagnosis in which an aortic prosthetic valve is normal structurally, but hemodynamically functions as aortic stenosis, with higher prosthetic valve gradients than would be expected for that particular valve.1,2 The prosthetic valve functions as designed but hemodynamics are less than ideal compared with a native valve. The predominan...

INTRODUCTION AND OBJECTIVES There have been no studies conducted in the past that focus on the significance of congestive heart failure in patients with prosthetic valve endocarditis. We studied the incidence of congestive heart failure in patients with prosthetic valve endocarditis and analyzed its profile. In this study, we addressed the prognostic significance of heart failure in patients wi...

The electron transport particle prepared from beef heart mitochondria contains two flavoprotein enzymes in approximately equal amounts: (a) the succinic dehydrogenase and (a) the reduced diphosphopyridine nucleotide dehydrogenase (1). When the electron transport particle is exposed to 9 per cent ethanol and pH 5 at 38’, the DPNH dehydrogenase is liberated from the particle almost quantitatively...

OBJECTIVE To determine whether any common maternal-fetal variable has prenatal predictive value of prosthetic repair in congenital diaphragmatic hernia. METHODS This was a 5-year single-center retrospective review of fetal congenital diaphragmatic hernia referrals. Multiple prenatal variables were correlated with the need for a prosthetic repair. Statistical analyses were by Fisher's exact an...

The prosthetic sockets of 14 independent persons with unilateral trans-tibial (BK) amputation were mounted on an adjustable alignment pylon. Vertical ground reaction forces were recorded in neutral prosthetic alignment and in 10 degrees of prosthetic socket varus, valgus, flexion, and extension. Stance phase time, peak vertical ground reaction force, and impulse were all found to be increased o...
