Quels sont les bienfaits de la recherche médicale?

Le 20eme siècle a connu des progrès considérables dans le secteur de la recherche médicale et scientifique. Les efforts soutenus des scientifiques ont aboutis à de nombreux succès dans la bataille contre les maladies autrefois dites incurables et ils ont beaucoup contribués à améliorer la santé à travers le monde.

Grâce aux recherches dans le milieu médical, l’espérance de vie chez les êtres humains est passée de 40 ans à 70 ans au 20eme siècle. La mort infantile a nettement diminué car il existe, de nos jours, des vaccins contre les maladies mortelles pour les nouveaux nées. Il est même possible de suivre le développement d’un fétus et de le soigner au cas ou il aurait des complications prénatales. Cependant, la longévité de la vie humaine peut progressivement entraîner une surpopulation accrue.

Des maladies qui affligent un grand nombre de personnes, telles les maladies cardio-vasculaires et les maladies respiratoires, sont beaucoup plus faciles à traiter aujourd’hui et causent moins de décès grâce à la recherche. Les maladies transmissibles qui ravageaient les pays pauvres sont aussi en déclin. Grâce à l’apport des nouveaux médicaments, la variole a été éradiquée en 1977. Depuis vingt ans, les infections de polio ont aussi été réduites de 99%. La prédominance de la lèpre a baissé de 90% depuis 1990.

Aussi, le progrès médical permet désormais de transplanter des organes, tel que le rein, d’un donneur vivant ou mort à un receveur. Une transplantation semble être un miracle médical. Réaliser une telle opération constitue le plus souvent le moyen de sauver une vie, c’est l’unique chance pour le patient de survivre. Dans certains cas, la transplantation peut également être utilisée pour améliorer la qualité de vie du patient. La vie du patient n’est alors pas menacée par la maladie dont il souffre.

Autre trouvaille dans la médecine reste la découverte sur les cellules souches

    The patient will receive doses of antiviral prophylaxis either orally or by injection consistently for several months. As the patient shows progress and recovery the dosage is steadily decreased until the body becomes completely self-sufficient. Putting the disease concern to rest another opposition of organ transplants can come in the form of broken or fractured bones. When an individual receives a transplant the bone structure around the area can become under pressure from the swelling organ trying to recover. A study was conducted in 1994 and scientists were shocked to find “fracture incidence was 13 times higher than expected in male heart recipients age 45–64 years; nearly 5 times higher in male kidney recipients age 25–44 and age 45–64 years; and 18 times and 34 times higher in female kidney recipients age 25–44 years and 45–64 years compared with NHIS data” (Department of Medicine, 1999). The study was taken from six hundred patients and out of those six hundred fifty six individuals had fractures during their recoveries. Another aspect in the recovery process is the fact that the patient’s body will be weak and low on nutrients due to the lack of food intake and nutrients. The longer a person’s recovery period the more likely he or she could develop weak muscle tissue, and bone structure leading to more incidents. The care programs developed in this day and age not only surpass any rehabilitation abilities from 1994. Now…

    Abstract Organ transplant saves many lives, but there are many ethical and moral issues involved in organ transplant. Some of the issues ethical issues involved in transplantation include who gets the organs, how many organs each patient gets, and how patients move up on the transplant list. There is a shortage of organs available for transplant in regard to the number of patients that need organ transplantation. Would compensation for the organs donated increase the number of people willing to donate? Compensation or incentives for donating organs is an ethical dilemma itself. Many of them will always exist.…

    The layout Ivan Illich is making in the article called, “Medical Nemesis,” is focused on medical practices and how iatrogenic effects are caused by the diagnosis and manner of treatment by a physician. Throughout the years, iatrogenic effects have caused more suffering, “Than all accidents from traffic or industry.”(Illich) The effects listed in the article include: “Infection, depression, dysfunction, disability, and their specific diseases which fall under the iatrogenic effects category.”(Illich) In the article, Illich is stating an argument; most of the suffering caused in modern society is man-made. When trying to prolong life, it is almost like cheating death. History is a record of how the meaning of the word “Life” has evolved. Through the years, many treatments and practices of modern medicine have changed. A then, life threatening illness; is today a commonly treated infection. Illich’s argument is then stated in the way medical practice and industrialization have created negative effects on human life.…

    Why Is Death Important

    • 1085 Words

    Elective Ventilation is the procedure of putting a dying person on life support to keep their organs preserved for longer, in short, prolonging a donor’s inevitable death, in order to increase the chances of success of transplantation, as all organs deteriorate the longer they are out of a body, and some organs such as the heart, can be substantially damaged in the time between removal and transplantation. This poses a problem for donation and transplantation as under ‘body death’ the donor is still alive, as their heart is still beating, which to many, implies the doctor is killing the patient by taking away life support in order to donate, therefore not upholding the principle of Primum non nocere. This whole issue raises the question previously raised by Jonathan Glover of whether we believe ‘being alive is intrinsically valuable’ or whether ‘being conscious is intrinsically valuable’ as under the latter, Elective Ventilation is acceptable, allowing a higher chance of saving life, unlike the first, an opinion held by many religions under the premise of “sanctity of life”. Therefore the definition of death is an important question for the issue of donation and…

    The medieval period is normally not associated with advances in technology, nor with contributions that benefit society. Yet, our medicine today owes much of its development to physicians of that time. Medicine of that era was strongly influenced by superstition and the doctrine of the Christian church, and did not have much foundation for practical application.…
