Sickle Cell Disease

Sickle Cell Disease is an illness that affects people all across the globe. This paper will give a description of the sickness through the discussion of the causes, symptoms, and possible cures. Sickle Cell Disease (SCD) is a "group of inherited red blood cell disorders."(1) These disorders can have various afflictions, such as pain, damage and a low blood count--Sickle Cell Anemia. The overall incidence of SCD is eight out of 100,000 people. However, it is much more widespread in some people....

Sickle Cell Disease

Sickle-Cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin. These hemoglobin molecules tend to aggregate after unloading oxygen forming long, rod-like structures that force the red cells to assume a sickle shape. Unlike normal red cells, which are usually smooth and malleable, the sickle red cells cannot squeeze through small blood vessels. When the sickle cells block small blood vessels, the organs are deprived of blood and oxygen. This leads to periodic...

Sickle Cell Disease

Sickle Cell Disease Physical-Adult • Eye problems. The retina, the "film" at the back of the eye that receives and processes visual images, can deteriorate when it does not get enough nourishment from circulating red blood cells. Damage to the retina can be serious enough to cause blindness. • Jaundice, or yellowing of the skin, eyes, and mouth. Yellowing of skin and eyes. These are signs of jaundice, resulting from rapid breakdown of red blood cells. • Delayed growth and puberty in children...

Sickle Cell Disease

09/08/2012 Sickle Cell Disease Blood has been considered the essence of life for centuries, and our blood is a living tissue made up of liquid and solids. There are many diseases related to blood such as anemia which is the decrease in oxygen supply to tissue and causes hypoxia, thalassemia is the mutation in one or more globin gene of hemoglobin, etc. Therefore, one of blood disorders is the most common symptomatic hemoglobinopathy with the greatest prevalence in worldwide which is called sickle cell...

sickle cell disease

‘How could natural selection increase the number of children born with sickle-cell disease in certain regions when these individuals are unlikely to survive and produce offspring?’ Darwin’s theory proposes that 3 conditions are a requisite for natural selection to occur. They are a struggle for existence of the offspring as they are competing for limited resources, variation within species which gives some individuals advantage over others hence better chance of survival and lastly inheritance...

Sickle Cell Disease

TREATMENT OPTIONS There is NO cure for sickle cell disease, although new stem cell research is promising. Bone marrow transplant is a potential cure, however finding a matched sibling donor is difficult. Therefore treatment is primarily focused on management of symptoms and prevention of pain episodes. Hydroxyurea (a chemotherapeutic medication) is the only recognized treatment option for the prevention of vaso-occlusive crisis in SCD. It is a prescribed drug for adult patients...

Evolution of Disease Sickle Cell Anemia

Evolution of Disease Sickle Cell Anemia Sickle Cell Anemia is a disease that which the red blood cells form an abnormal sickle or crescents shape. Red blood cells are very important to the human body because they carry oxygen throughout the body. The main causes of Sickle cell is when the cells in the body mutate into abnormal cell called haemoglobin S. Haemoglobin S causes the red blood cells to become sickle shaped, rigid. This causes to make it more difficult for the cells to flow the vein...

Case Study Sickle Cell Disease

Case Study 97 1. Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape. SCD affects millions of people worldwide, particularly those with African, Spanish, Mediterranean, and Indian ancestry. Some 120,000 infants are born with SCD every year worldwide...

Sickle Cell

Sickle Cell Anemia is a hereditary disease that changes the smallest and most important components of the body. A gene causes the bone marrow in the body to make sickled shapes, when this happens; it causes the red blood cell to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may experience a few complications, or have a pattern of ongoing problems that shorten their lives. The most common and serious complications of sickle cell disease are anemia...

Sickle Cell

Sickle cell disease is present usually in those of African or Mediterranean descent (Saladin 2007). About 1.3% of African Americans have sickle cell (Saladin, 2007). Sickle cell was originated in Africa where malaria was killing a vast number of people (Saladin, 2007). The sickle cell hemoglobin is not able to be digested by the parasites that cause malaria, making those with sickle cell resistant to malaria (Saladin, 2007). This paper will discuss a normal erythrocyte compared to an erythrocyte...
