Also, the person will often need to take larger amounts of the drug to produce the familiar dopamine high—an effect known as tolerance.

To look at only one piece and try to understand the benefits and risks is like standing an inch away from an elephant and trying to describe everything about it generic minocycline 50mg amex antibiotics for acne south africa. Each specialty discount minocycline 50 mg on-line infection control training, each division of medicine keeps its own records and data on morbidity and mortality. We have now completed the painstaking work of reviewing thousands of studies and putting pieces of the puzzle together. Because of the extraordinarily narrow, technologically driven context in which contemporary medicine examines the human condition, we are completely missing the larger picture. Medicine is not taking into consideration the following critically important aspects of a healthy human organism: (a) stress and how it adversely affects the immune system and life processes; (b) insufficient exercise; (c) excessive caloric intake; (d) highly processed and denatured foods grown in denatured and chemically damaged soil; and (e) exposure to tens of thousands of environmental toxins. Instead of minimizing these disease-causing factors, we cause more illness through medical technology, diagnostic testing, overuse of medical and surgical procedures, and overuse of pharmaceutical drugs. The huge disservice of this therapeutic strategy is the result of little effort or money being spent on preventing disease. Underreporting of Iatrogenic Events As few as 5% and no more than 20% of iatrogenic acts are ever reported. In 1994, Leape said his figure of 180,000 medical mistakes resulting in death annually was equivalent to three jumbo-jet crashes every two days. What we must deduce from this report is that medicine is in need of complete and total reform—from the curriculum in medical schools to protecting patients from excessive medical intervention. It is obvious that we cannot change anything if we are not honest about what needs to be changed. We are fully aware of what stands in the way of change: powerful pharmaceutical and medical technology companies, along with other powerful groups with enormous vested interests in the business of medicine. They fund medical research, support medical schools and hospitals, and advertise in medical journals. Such funding can sway the balance of opinion from professional caution to uncritical acceptance of new therapies and drugs. You have only to look at the people who make up the hospital, medical, and government health advisory boards to see conflicts of interest. Erik Campbell, the lead author, said, "Our previous research with faculty has shown us that ties to industry can affect scientific behavior, leading to such things as trade secrecy and delays in publishing research. Marcia Angell struggled to bring greater attention to the problem of commercializing scientific research. In June 2002, the New England Journal of Medicine announced that it would accept journalists who accept money from drug companies because it was too difficult to find ones who have no ties. Jerome Kassirer, said that was not the case and that plenty of researchers are available who do not work for drug companies. Cynthia Crossen, a staffer for the Wall Street Journal, i n 1996 published Tainted Truth : The Manipulation of Fact in America , a book about the widespread practice of lying with statistics. In 1981 Steel reported that 36% of hospitalized patients experienced iatrogenesis with a 25% fatality rate, and adverse drug reactions were involved in 50% of the injuries. In 1991, Bedell reported that 64% of acute heart attacks in one hospital were preventable and were mostly due to adverse drug reactions. Leape focused on the “Harvard Medical Practice Study” published in 1991, (16a) which found a 4% iatrogenic injury rate for patients, with a 14% fatality rate, in 1984 in New York State. From the 98,609 patients injured and the 14% fatality rate, he estimated that in the entire U. Why Leape chose to use the much lower figure of 4% injury for his analysis remains in question. Using instead the average of the rates found in the three studies he cites (36%, 20%, and 4%) would have produced a 20% medical error rate. The number of iatrogenic deaths using an average rate of injury and his 14% fatality rate would be 1,189,576. Leape acknowledged that the literature on medical errors is sparse and represents only the tip of the iceberg, noting that when errors are specifically sought out, reported rates are “distressingly high. First, he found that each patient had an average of 178 “activities” (staff/procedure/medical interactions) a day, of which 1. This may not seem like much, but Leape cited industry standards showing that in aviation, a 0.
