Myeloproliferative and myelodysplastic syndromes, two diverse groups of bone marrow disorders, are respectively characterized by an overproliferation or ineffective production of various blood cells. The clinical laboratory plays a prominent role in the diagnosis and classification of myeloproliferative and myelodysplastic disorders, each of which presents a unique set of morphologic, pathophysiologic, and genetic traits. The contemporary diagnosis and categorization of these syndromes emphasizes a combination of hematologic bone marrow characterization and gene mutation studies.
HEMATOLOGIC CHARACTERISTICS OF MYELOPROLIFERATIVE NEOPLASMS
Myeloproliferative neoplasms (MPNs) are characterized by the proliferation of one or more cell types of the myeloid lineage, including erythroid, granulocytic, monocytic, or megakaryocytic lineages. These disorders are clonal and originate from a single pluripotent hemapoietic stem cell (Hubbard, 2011). MPNs have a slow onset and are mainly diagnosed in adults between 45 and 55 years of age. Clinical symptoms include anemia, weight loss, lack of energy, spleen enlargement, fever, and bruising (Hubbard, 2011).
The major diagnostic criterion for chronic myelogenous leukemia (CML) is the presence of the Philadelphia chromosome (Ph+), a reciprocal translocation between chromosomes 9 and 22, and the presence of the BCR/ABL1 fusion gene. Peripheral blood shows leukocytosis (>100×109 WBC/L), a predominance of myelocytes and segmented neutrophils
Mr. Jacobs is a very pleasant, 69-year-old gentleman who presents to the oncology clinic for evaluation and treatment of a myelodysplastic syndrome with excess blasts in transformation RAEB-2. Patient states he was in a normal state of health until 01/2017 when he was evaluated to have anemia and leukopenia. He was referred to a hematologist/oncologist and underwent a bone marrow biopsy. The results revealed a mild dysplastic syndrome with excess blasts in transformation RAEB-2. Flow cytometry showed 11% myeloblasts. He was subsequently given one unit of packed red blood cells and started on erythropoietin every three weeks
DK is a 51-year old male patient presenting with Acute Myeloid Leukemia AML. Two weeks ago while vacationing in Ocean City with his family, DK visited the local hospital with the symptoms of swollen leg, difficulty walking, pain, and fever. Bloodwork was performed at the local clinic and revealed anemia and low cell counts indicating possible leukemia. Patient returned to Baltimore and was admitted to Johns Hopkins Hospital 1 week ago. His current symptoms are swelling of lower legs, fever, low blood Oxygen level, anemia.
Multiple myeloma (also plasma cell myeloma also known as MM, myeloma, plasma cell myeloma, or as Kahler's disease) is a progressive hematologic (blood) disease. It is a cancer of the plasma cell, an important part of the immune system that produces immunoglobulins (antibodies) to help fight infection and disease.

It takes about 15 days for lab results to be complete once samples are received. The FADL emails lab results to the requestor and will CC you in the email. It is important that you keep track of the lab results; you will need to make a deposition for all lab positive or failed lab results. Notify CW5 Finch or APHC representative when samples contain pathogens. AR 40_657.pdf Chapter 5 section 5-6 give detailed instruction for nonconforming lab samples. When you receive a positive sample lab result that is non-pathogenic, you will make the decision on the which course of action to take. Recently I received lab results for product that had a high SPC counts. I contacted the facility management address the issue, issued the manager
People who have Myelodysplastic Syndrome may not experience symptoms at the beginning of the disease. However, there are three main signs that can develop and alert healthcare providers that something is wrong. One of these is a low red blood cell count, or Anemia. Most patients that have myelodysplastic syndromes exhibit this indicator when first diagnosed. A normal red blood count can vary between 4.0 and 6.1 million red blood cells per microliter of blood in the body, depending on the age and sex of the patient. A red blood cell count lower than normal is characteristic of Anemia (Cafasso, Jacquelyn, and Gotter). Not only is Anemia shown by constantly low hematocrit, but it can also be characterized by constantly low hemoglobin. A normal hemoglobin count is between 12.0 and 15.5 grams per deciliter of blood for females, and 13.5 to 17.5 grams per deciliter of blood for males. Levels lower than these show a low hemoglobin level (Mayo Clinic, Hemoglobin Test). Hemoglobin is the protein in blood that carries oxygen to the different tissues in the body.
Low blood counts are a key feature of myelodysplastic syndrome which is the reason for the many symptoms these patients experience. The three types of cytopenia that people with Myelodysplastic Syndrome experience are anemia, neutropenia, and thrombocytopenia which are all low blood cell counts of the three blood cells. Cytopenias can cause anemia, the inability to fight off infections, easy bruising, and spontaneous bleeding. This can be due to the lack of blood cells in the blood stream, but also from dysplasia of the blood cells from the disease. If the cell is deformed, it may not be able to provide the same function as a healthy cell, resulting in the same effect as having cytopenia. Myelodysplastic syndrome is a gradual process and is
Multiple myeloma (MM) is a rare life-threatening cancer that affects the white blood cells known as plasma cells that are found in the soft, spongy tissue at the center of the bones, called bone marrow. The plasma cells are useful in fighting infections by producing antibodies that recognize and attack germs. The plasma cells are transformed into malignant myeloma cells when there are high levels of M proteins or better known as the production of abnormal antibodies from a result of myeloma cells. These M proteins multiple and block out normally functioning antibodies and the end results are bone damage or kidney problems. An individual can have blood tests or urine tests done to determine if they have multiple myeloma. In the article, “The work of living with a rare cancer: multiple myeloma” the authors explain how this type of cancer still remains incurable, but treatable that patients can expect to live longer, approximately five to seven years than what two decades ago. This was not expected for patients diagnosed with multiple myeloma during the 1990s, since patients were expected to only live about two and a half years after being diagnosed. Treatment for multiple myeloma throughout the years has advanced greatly yet a cure is still to be discovered. This essay will focus of the causes, the sign and symptoms, how multiple myeloma is detected and diagnosed, and how multiple myeloma is treated.
Acute Lymphoblastic Leukemia, is the disease that affects children the most and because of the abnormal cells that are immature white blood cells which cannot help the body fight infections cause children with the disease to often get infections and have fevers (National Cancer Institute, 2002, p. 1). The symptoms that the patient with ALL may have depend on the number of abnormal cells of the patient where exactly the cells collect. Children patients with ALL have low amounts of healthy red blood cells and platelets, which cause less oxygen to be carried through the body because of the lack of red blood cells. Patients at times may look pale, feel weak, and tired causing bleeding and bruising very easily because of their lack of enough platelets. This condition is called anemia. Anemia is very much common in patients with acute lymphoblastic leukemia. Fever, fatigue, bone or joint pain, tiny red spots under the skin called petechiae are a couple of symptoms that the disease ALL has. Headaches with, or without vomiting also may occur if patient happens to have abnormal cells collecting in the brain or spinal cord (National Cancer Institute, 2002 para. 2).
Multiple Myeloma is a form of cancer which affects the plasma cells of the body, which are white blood cells. Multiple Myeloma, first described in 1848, is a disease “characterized by a proliferation of malignant plasma cells and a subsequent overabundance of monoclonal paraprotein.” To understand how Multiple Myeloma affects an infected person’s plasma cells, it helps to have a general understanding of how normal blood cells are formed and how they act. Most blood cells develop from stem cells, which can be found in bone marrow (soft material inside our bones – the “filling”). Stem cells mature into white blood cells, red blood cells, or platelets.2 The purpose of white blood cells is to fight off infection, while
Leukemia is a cancer that affects the bone marrow. The bon marrow is the soft spongy center of the bone that produces blood cells. Leukemia is found in white blood cells or leukocytes. The white blood cells help to fight ff infections and other diseases. Normally, cells produce in an orderly way, but people that have leukemia the cell production gets out of control. The marrow produces too many immature white blood cells called blasts. They are differently shaped and can’t carry out their usual duties.
Myeloma is a cancerous disease whose cause is plasma cells, which are one of the four major components that make up blood in a human body. Manufacture of the plasma takes place in the bone marrow and the main function of the plasma is help the body fight infections. Multiple myeloma is another name for myeloma in fact it is the more recognized name. The plasma of a healthy human body is responsible for the production of antibodies, which fight disease-causing infections. The plasma of a diseased human body with myeloma causes the uncontrollable multiplication of these plasma cells. The myeloma affects these plasma cells to extent that they start to produce one antibody, which is nonfunctioning
Multiple Myeloma is a neoplastic disease that involves the plasma cells within bone marrow. Plasma cells are a type of white blood cell that helps make up our immune system. They work within our immune system by generating antibodies that guard us from microorganisms and other unsafe materials. Although multiple myeloma forms in the immune system, the abnormal antibodies decrease the effectiveness of the body ability to fight infection. Since multiple myeloma is an uncommon cancer, the etiology is idiopathic, unknown. When plasma cells start to divide rapidly they become abnormal, and this is when myeloma starts. Healthy patients have a 5%
• A bone marrow sample helps find signs of cancer that could be affecting blood production.
The Death Penalty is, undeniably, one of the most controversial issues of our day. Emotional tensions are high between those who hold human life above justice and those who hold justice above all human life. The Death Penalty, along with all other forms of criminal punishment, is barbaric. This form of punishment, indeed all forms of criminal justice, truly shows the level to which society has sunk. When people stand outside prisons and cheer as prisoners are murdered, there is a problem. When personal bloodlust is held above moral ideologies, there is a problem. When human life is assigned a value and weighed against other alternatives, there is a problem. The state speaks of Justice, but this word is only a reflection of the confusion,
