In the last 40 years, the emergence of bone marrow transplants as a therapeutic modality for fatal disease and as a curative option for individuals born with inherited disorders that carry limited life expectancy and poor quality of life (G). Over 4,500 hematopoietic stem cell [bone marrow] transplants performed on patients in the United States annually (H). Bone marrow transplants originally developed to allow the use of very high doses of cytotoxic drug treatments for malignancies, such as leukemia (B). Two types of possible donors: mismatched related donors [mmRD] and matched sibling donors [MSD] (E). Although bone marrow transplants seem promising, there can be drawbacks to this procedure. Graft-versus-host disease, where the body attacks itself, being the major obstacle. The purpose of this paper is to inform one about transplants and to see if this is a high-quality study to cure malignancy diseases.
Physicians since ancient times had the idea of removing damaged parts of the body and replacing them with healthy organs to cure the patient with a disease. World War II brought research in tissue transplantation to the forefront: skin grafts for burn victims, blood transfusions required careful AOB blood typing and monitoring of blood group antibodies; and high doses of radiation lead to bone marrow failure and death. Massive radiation exposures provided an opportunity for advancement therapies for bone marrow failure syndrome and leukemia. The concept of the bone marrow transplants to treat humans with inherited disease of the immune system, marrow failure syndrome, and leukemia met with much doubt, enthusiasm, and also many disappointments. Transferring what the physicians knew from experimental trails with animal models t...

... it, which destroys all healthy bone marrow in the body. As a result of this, the patient will have to undergo a process to replace all deteriorated or damaged bone marrow. This process involves taking the stem cells from a donor and transplanting them into the patient’s body, so that the patient will transform these stem cells into bone marrow. Bone marrow can also be a complication for the body if it escapes into the blood stream. If the bone marrow enters the blood stream, it can travel throughout the body, and cause serious complications. This is a condition referred to as fat embolism, and mainly occurs after serious trauma or surgery to lower limbs. There is not a specific diagnosis or treatment for this; it is mostly based on the patient’s condition or symptoms. Bone marrow can be a very dangerous thing if it has any type of complications within the body.
Specific Purpose: After listening to my speech, my audience will know the history of organ transplants/transplantation and its medical advances over the years.
Disease can damage blood marrow and tissue. In order to repair this damage, doctors can transplant the stem cells described above into the patient in need. There are a few different names for this kind of transplant procedure. They are: bone marrow transplant, a peripheral blood stem cell transplant, and a cord blood transplant (American Cancer Society, 2013). The process of transplanting these hematopoietic stem cells involves a number of complex steps. The first step involves the patient receiving chemotherapy and/or radiation, which kill the diseased cells. This “conditions” the area (Dana-Farber Cancer Institute, 2014). Next, healthy stem cells are infused into this conditioned area. “These transplanted stem cells will begin to grow and produce healthy red and white blood cells and platelets” (Dana-Farber Can...

Currently more than 118,617 men, women, and children are waiting for a transplant. With this high demand of organ transplants there is a need of supply. According to the OPTN Annual report of 2008, the median national waiting time for a heart transplant is 113 days, 141 days for lungs, 361 days for livers, 1219 days for kidneys, 260 days for pancreas, 159 days for any part of the intestine. With this world of diseases and conditions, we are in desperate desideratum of organs. Organ transplants followed by blood into a donating organ transfusions, are ways medical procedures are helping better the lives of the patients.

The patient presented in this paper is Ms. H an 83 year old African American woman that appears younger than stated age with a history of Multiple Myeloma. The patient chart was reviewed and an interview conducted. Interestingly the patient had retained every note, lab, hospital H&P and discharge summary in a file folder in her possession. Ms. H was diagnosed with Multiple Myeloma in April of 2008 when she was being worked up at her dentist for a toothache. X-rays performed revealed she had bone lesions in her zygomatic process and in her skull above her right eye. She was referred to Oncology Hematology Care for further work-up. A bone marrow biopsy revealed she had Multiple Myeloma. During the course of treatment the patient received Thalidomide, Revlimid, Velcade, Aredia, Zometa, and Decadron. Remission was achieved and the patient underwent stem cell transplant in February of 2009. The transplant was successful and the patient was cancer free until August of 2012 when she received news that her cancer had recurred.
Many doctors are trying to find cures for this disease by trying the solution on patients. Doctors at Emory University and University of Mississippi Medical Center in Jackson, Chicago. Doctors in Emory University in Atlanta credited an experimental stem cell transplant that for the first time is not from a related donor. This transplant cured the inherited disease from Keone Penn who is 13 years old from Georgia. He suffered a stroke at 5 years old and had a fever of 106 degrees, "I almost died" (Ferraro, Newspaper Article) What the doctors did was replaced the boy's bone marrow with stem cells taken from the umbilical cord blood of an infant not related to him. Dr. Ruby Bellevue of New York Methodist Hospital in Brooklyn has patient that he wants to do the transplant procedure on, but he is waiting for more studies to come out to see what the long-term effects are. Some effects could be rejection, complications, and/or death.
Although there are many arguments against embryonic stem cell research, there have already been many success stories because of stem cells. Through bone marrow transplants and stem cell transplants many people survived illnesses against the odds. A bone marrow transplant is when bone marrow from a

...matopoietic compartment using integrating vectors particularly need to understand genotoxicity risks in relation to the risks of conventional bone marrow transplantation. A QPL could direct them to ask questions about risk, benefits and survival rates following transplantation at local centres; the prognosis of patients in the different haematopoietic gene therapy trials; the number and status of patients that developed leukaemia in the SCID-X1 gene therapy trials; and whether there are any differences between the proposed vector and the vector used in the SCID-X1 trial and any possible safety developments. This kind of guidance may help patients understand both what is known and unknown about specific applications of gene therapy.

One of the most beneficial aspects to cloning is the ability to duplicate organs. Many patients in hospitals are waiting for transplants and many of them are dying because they are not receiving a needed organ. To solve this problem, scientists have been using embryonic stem cells to produce organs or tissues to repair or replace damaged ones (Human Cloning). Skin for burn victims, brain cells for the brain damaged, hearts, lungs, livers, and kidneys can all be produced. By combining the technology of stem cell research and human cloning, it will be possible to produce the needed tissues and organs for patients in desperate need for a transplant (Human Cloning). The waiting list for transplants will become a lot shorter and a lot less people will have to suff...
The first successful case of stem cell therapy in human was reported in 1959. Bone marrow restorations were observed in leukemia patients who received total body irradiation subsequent by intravenous injection of their twins’ bone marrow (Thomas et al, 1957). Nevertheless, that effect was transient and the following bone marrow transplantation attempts in non-twin patients and donors can eventually lead to patient’s death from graft-versus-host disease (Mathé et al, 1965). During that time, the safety of hematopoietic cells transplantation was not guaranteed because of the limited knowledge in human histocompatibility and immunosuppression. However, the turning point came after the discovery of human leucocyte antigen (HLA) groups (Dausset, 1958; van Rood et al, 1958), HLA typing and compatibility testing were performed prior to the transplantation. In addition, the improvement of immunosuppressive protocol also helps bringing the bone marrow transplantation to become more and more successful (Donnall and Hutchinson, 1999).
Organ transplants have been done in the United States since the 1950; Organ donations takes healthy organs and tissues from a human body, from a living or a dead person for transplantation into another. Transplanted organs and tissues replace diseased, damaged, or destroyed body parts. They can help restore the health of a person who might otherwise die or be seriously disabled .doctor first assesses whether the person is medically eligible for a transplant. If so, the doctor then refers the individual to a local transplant center. The transplant center evaluates the patient’s health and mental status as well as the level of social support to see if the person is a viable candidate for an organ transplant. once a person is accepted as a transplant candidate, the patient must wait until suitable donor organs are found, Organs and tissues that can be donated and used for transplants include kidneys, lungs, heart,...
