BACKGROUNDIn view of the almost certain mortality of the acquired immune deficiency syndrome (AIDS) patient, controversy may arise as to how to treat those individuals with concomitant aneurysmal disease.METHODSWe conducted a retrospective case review of six patients seen in a 1-year period, who had a history of either being positive for human immunodeficiency virus (HIV) or prior opportunistic pneumonias...
The story of treatment of patello-femoral instability is one of failure rather than success. Insall has pointed out that 30% have had more than one procedure.80% good results30% second operation6-40% redislocation43% persistent maltracking35% P/F crepitus22% +ve apprehensionThe reasons for this are clear. There is confusion and lack of uniformity about the classification of these conditions. There...
There is growing evidence to support some form of light-activated phosphoinositide signal transduction pathway in the mammalian retina. Although this pathway plays no obvious role in mammalian phototransduction, mutations in this pathway cause retinal degenerations in Drosophila. These include the retinal degeneration A mutant, which is caused by an alteration in an eye-specific diacylglycerol kinase...
This communication describes a real-time data acquisition system for the visualisation and analysis of cardiac activation sequences. The system uses digital signal processing and graphics workstation technology to support three-dimensional visualisation of cardiac activation in real-time. A high speed data acquisition interface for Unix workstations is described. Use of this interface results in no...
Seventy patients surviving a myocardial infarction complicated by heart failure or arrhythmias, or both, were studied 7 to 20 days after the infarction. Twenty-four hour electrocardiographic ambulatory monitoring and intracardiac electrophysiologic studies were performed in each patient. Electrophysiologic studies included introduction of single right ventricular premature stimuli during sinus rhythm...
