HTLV-III: should testing ever be routine?
The authors--who are researchers, physicians, and psychologists at a London teaching hospital--reject routine, indiscriminate screening for HTLV-III antibodies as of limited use in the diagnosis of acquired immunodeficiency syndrome (AIDS); as an ineffective public health measure; and as psychologically, socially, and economically damaging to persons with positive results. They are in favor of...
متن کاملShould Static Search Trees Ever Be Unbalanced?
In this paper we study the question of whether or not a static search tree should ever be unbalanced. We present several methods to restructure an unbalanced k-ary search tree T into a new tree R that preserves many of the properties of T while having a height of log k n+1 which is one unit off of the optimal height. More specifically, we show that it is possible to ensure that the depth of the...
متن کاملShould routine platelet testing be done on all patients undergoing percutaneous coronary intervention? Routine Platelet Testing Should Not Be Performed on All Patients Undergoing Percutaneous Coronary Intervention
We all know that clopidogrel reduces thrombotic complications during and after a percutaneous coronary intervention (PCI) procedure. Because clopidogrel is a prodrug and only 2% of ingested clopidogrel is ultimately bound to platelets, it is entirely possible, even likely, that small differences in metabolism that lead to a reduction in the formation of the active metabolite could potentially h...
متن کاملIntensive monitoring should not be the routine.
The main objective of acute stroke care should be to reduce death and disability, and the objective of monitoring should be the same. Treatment in stroke units (without intensive monitoring) is the only treatment option proven to reduce death in acute stroke patients, and also the only treatment that has shown beneficial long-term effects on survival and disability.1 All acute stroke patients s...
متن کاملRoutine tests should be challenged in cardiology.
The need for routine diagnostic tests and procedures needs to be challenged in medical practice, because of continuous pressure to reduce the costs of health care systems. If costs can be minimized by avoidance of routine tests, more sources can perhaps be directed to new advanced diagnostic and therapeutic procedures. This challenge is important particularly in cardiology, because while new di...
