What is the difference between Hemophilia A and Hemophilia B?
There are two types of hemophilia: hemophilia A (sometimes called classical hemophilia) and hemophilia B (sometimes called Christmas disease). Both are caused by a low level or absence of one of the proteins in the blood (called factors) that control bleeding. Hemophilia A is caused by a deficiency of factor VIII, and hemophilia B is caused by a deficiency of factor IX. There is no difference between the two types of hemophilia, except that hemophilia B is about five times less common than hemophilia A.
What is a group of hereditary bleeding disorders in which a blood-clotting factor is missing?
Hemophilia is a group of hereditary bleeding disorders characterized by a deficiency in clotting factors, specifically factor VIII (hemophilia A) or factor IX (hemophilia B). These deficiencies result in prolonged bleeding episodes, especially in response to injury or trauma. Treatment typically involves replacement therapy to restore the missing clotting factor.
Where are clotting factors made in the body?
All are made in the liver except for Factor VIII (made by the vascular endothelium) and vonWillebrand's factor which is made in the endothelium (in the Weibel-Palade bodies), megakaryocytes (α-granules of platelets), and subendothelial connective tissue.
Why is haemophilia a lethal gene in its homozygous state?
Heamophilia A is caused by an impairment of a protein (clotting factor VIII deficiency) which is used to prevent clots. It is also used to produce fibrin, which is used in platelet activation. Without platelets, cellular differentiation is severely limited, leading to pre-natal death.
What is von Willebrand's disease?
The von Willebrand disease creates the tendency to bleed and bruise easily. It is an inherited clotting disorder that is usually less severe but more common. Those affected lack a plasma protein. Von Willebrand factor enables platelets to adhere to damaged blood vessel walls.
What is the cpt code for clotting factor XII (Hageman factor) for excessive bleeding menopausal onset?
627.0
Heamophilia is an example of what?
Hemophilia is an example of a genetic disorder that affects the body's ability to form blood clots, leading to excessive bleeding and bruising. It is caused by a deficiency in clotting factors, most commonly factor VIII or IX.
Is an x-linked recessive bleeding disorder caused by a missing coagulation factor?
Yes, the disorder you are referring to is hemophilia A, which is caused by a deficiency or missing factor VIII in the blood. This results in impaired blood clotting and leads to prolonged bleeding after injury or surgery. It is inherited in an X-linked recessive pattern, meaning it predominantly affects males.
What is the meaning of the word hemophilia?
any of several X-linked genetic disorders, symptomatic chiefly in males, in which excessive bleeding occurs owing to the absence or abnormality of a clotting factor in the blood.
Which clotting factor is deficient in Hemophilia A?
Hemophilia A is an X-linked, hereditary bleeding disorder caused by the absence or defect of a blood clotting protein, Factor VIII. As a result, when a person with hemophilia A has a bleeding episode, the bleeding may be prolonged due to the body's inability to form blood clots. Patients who are affected with hemophilia A experience frequent spontaneous bleeding, most commonly into their joints and soft tissues, with bleeding into vital organs that may ... be life-threatening. Bleeding episodes may be painful, and over time, recurrent joint bleeding may result in debilitating destruction of the joints. Currently, patients with hemophilia A are dependent on injections of Factor VIII produced by genetic engineering or purified from human plasma, to help control a bleeding episode. It is estimated that approximately 50,000 individuals worldwide are affected with hemophilia A. Hemophilia A - Clotting Factor VIII Hemophilia B - Clotting Factor IX Hemophilia C - Clotting Factor XI
What are three common deformities of the vertebral and at least one causative factor for each?
Three common deformities of the vertebral column include scoliosis, kyphosis, and lordosis. Scoliosis, characterized by an abnormal lateral curvature, can be caused by congenital factors or neuromuscular conditions. Kyphosis, which involves an exaggerated forward curve of the spine, may result from osteoporosis or degenerative diseases. Lordosis, marked by an excessive inward curve of the lower back, can be caused by obesity or muscular imbalances.
What condition caused by the absence of clotting factors resulting to uncontrolled bleeding?
The medical term - is Haemophilia. Sufferers cannot manufacture their own platelets (the cells that form blood clots). This means that they are at riskc of bleeding to death. However - they can be treated medically with injections of 'Factor 8'. Factor 8 is made from donations of platelets by blood donors.
What is the difference between Hemophilia A and Hemophilia B?
There are two types of hemophilia: hemophilia A (sometimes called classical hemophilia) and hemophilia B (sometimes called Christmas disease). Both are caused by a low level or absence of one of the proteins in the blood (called factors) that control bleeding. Hemophilia A is caused by a deficiency of factor VIII, and hemophilia B is caused by a deficiency of factor IX. There is no difference between the two types of hemophilia, except that hemophilia B is about five times less common than hemophilia A.
What Inherited lack of one blood-clotting factor?
An inherited lack of one blood-clotting factor typically refers to hemophilia, a genetic disorder that impairs the body's ability to make blood clots. This condition is usually caused by a deficiency in either factor VIII (hemophilia A) or factor IX (hemophilia B). Individuals with hemophilia may experience prolonged bleeding after injury, spontaneous bleeding, and joint pain due to internal bleeding. It's an X-linked recessive disorder, meaning it primarily affects males, while females can be carriers.
The absence of Factor VIII is indicative of which condition?
The absence of Factor VIII is indicative of hemophilia A, a genetic bleeding disorder where the blood does not clot properly. This can lead to prolonged bleeding episodes and difficulty stopping bleeding after injury or surgery.
What is the environmental factor that causes a predispostion to malignant melanoma?
The environmental factor is excessive sun exposure.
The most critical factor affecting safe privately owned vehicle operation is?
Excessive speed.
