Continue of : 20th-Century Medicine In 1929 the medicine community has proved that heart rate disorders can be regulated by defibrillation.(*) Treatment of psychosis by lobotomy and electroconvulsive therapy began in the 1930s, although these are now seldom used. Drug therapy for mental illness became possible in the 1950s. The first drugs widely used to treat schizophrenia, the phenothiazines, have since been joined by lithium for manic depressive disease and tricyclic antidepressants for depression. Despite these successes, physicians now realize that some patients are not helped by drugs, and that supportive psychological therapy must be provided as well. Heart disease, the number one killer in Western countries, has declined dramatically because of recent medical advances such as cardiac catheterization, angiography, nerve-blocking drugs, heart valve replacement, arterial bypass surgery, and heart transplants. The first pre-hospital successful CPR (Cardio-Pulmonary Resuscitation) was on Jan , 6 , 1960. The Resuscitation procedures were according to the guide-lines and techniques methods of Johns Hopkins Hospital , Baltimore , Maryland. (*) |

Increased awareness of the risks of smoking, stress, obesity, high blood pressure, and elevated blood cholesterol have also helped reduce heart disease. Cancer has become more prevalent in the 20th century. Research has linked some cancers with exposure to certain chemicals; smoking is known to cause lung cancer and other cancers. Surgery and radiation were primary means of treatment until the 1960s, when drug therapy also became effective against cancer. The discovery of vitamins and their importance to the body produced important advances in nutritional medicine. An example is the discovery of vitamin B12 and its use to treat pernicious anemia. Similarly, improved understanding of the hormones led to better control of conditions such as hypothyroidism or cretinism, treated with thyroid extract (see Thyroid Gland), diabetes mellitus, treated with insulin, and various reproductive disorders, treated with synthetic testosterone and estrogen. Advances have been made in birth control with the improvement of interuterine devices and the development of oral contraceptives. Solutions to some fertility problems have been provided by in vitro fertilization ("test-tube" babies) and transplantation of fertilized ova from one womb to another. Diagnosis of some birth defects can now be made through amniocentesis. In 1965 , external chest compression has proven as an efficient treatment due to cardiac arrest. (*) In 1967 , epidemiological statistics have shown that most death occurred within the first hours due to myocardial infarction .(*) Complex medical ethics problems have gained increasing attention, especially the question of abortion and the decision whether to remove life support systems from terminally ill patients. Medical treatments became increasingly expensive in the 20th century, and many people came to distrust the orthodox medical establishment. This situation led in the United States to the consumer medical movement, in which people attempted to take control of their own health, largely through preventive medical practices, and to understand more about normal and diseased bodily function. Outgrowths of the movement included many popular medical reference books and development of the field of holistic medicine, which promotes good nutrition, physical exercise, and "self-regulation" techniques, such as biofeedback and relaxation. |
