If adopted without adequate cause, the lifestyle of an invalid is a grave misfortune for the patient and for its reflection on current social attitudes that foster such states. Psychological illnesses are frequently invoked and are often a genuine source of suffering and disability. However, patients who may be rewarded by large financial settlements in courts, may also on occasion exaggerate their claims. ⋯ It is wrong to blame everything on society and to deny the free choice of the individual. Nevertheless, the pressures of society can be difficult to withstand for those not gifted with resilience. We should also recognise and try to eliminate the contribution made by doctors and health workers who mistakenly aid and abet a 'culture' that promotes this state of chronic disability

Editorial Comparative Study
The ABCs of research on pulsatile versus nonpulsatile perfusion during cardiopulmonary bypass.
The literature suggests that pulsatile flow should be routinely used during cardiopulmonary bypass (CPB) in moderate- to high-risk cardiac surgery patients, especially those who must undergo more than 45 minutes of aortic crossclamping. Nevertheless, the use of pulsatile versus nonpulsatile perfusion remains controversial, mainly owing to a lack of precise, complete quantification of pressure-flow waveforms. This editorial briefly summarizes the major factors, or 'basic ABCs, ' that affect the validity of research in this area. ⋯ C. In conducting clinical trials of the perfusion modes, researchers must use appropriate patient-selection criteria, use pulsatile flow continuously during CPB, and choose extracorporeal-circuit components carefully. By following these basic ABCs, researchers will produce more valid and meaningful results that will translate into better outcomes for CPB patients.
