Disseminated Intravascular Coagulation (DIC)

Definition of Disseminated Intravascular Coagulation and Treatment Disseminated intravascular coagulation (DIC) – a secondary coagulation disorder arising from an imbalance among the clotting factors in the blood. DIC occurs as a result of a significant underlying health condition such as HIV/AIDS, overwhelming infections, or cancer, and as a serious complication in pregnancy. DIC is a symptom rather than a condition. Indications of its […]

Sickle Cell Disease – Definition, Symptoms and Treatment

Definition of Sickle Cell Disease An inherited genetic disorder of defective hemoglobin, a protein compound erythrocytes (red blood cells) contain that binds with oxygen. Though the primary effect of sickle cell disease, also called sickle cell anemia, is anemia (insufficient oxygen in the blood), the condition also causes significant pain and damage to organs throughout the […]

Hematoma – Definition and Treatment

Definition of Hematoma Hematoma – Bleeding into the tissues that forms a contained mass. Most superficial hematomas are benign, such as the common hematoma auris, involving the auricle (outer ear) and black eye, involving the orbital tissues surrounding the eye. Such hematomas typically occur as the consequence of blows to the tissues that cause blood vessels to break. As […]

Thalassemia (alpha/beta) Disease – Symptoms and Treatment

Definition of Thalassemia alpha/beta Disease A genetic disorder of the blood in which the body fails to produce one or more of the proteins necessary for the synthesis of hemoglobin, the protein that enables erythrocytes (red blood cells) to carry oxygen. The consequence is anemia (inadequate oxygen to the cells throughout the body). There are two basic […]

Hemolysis – Definition and Conditions

Definition of Hemolysis The destruction and disassembly of erythrocytes (red blood cells). Erythrocytes live in the blood for about 120 days after their release from the bone marrow. At the end of this time they either die or the spleen culls them from circulation. The spleen partially dismantles the erythrocytes, reducing toxic heme into bilirubin […]

Thrombocythemia – Definition, Symptoms and Treatment

Definition of Thrombocythemia A condition of the blood in which the body overproduces platelets (also called thrombocytes), resulting in dysfunctional coagulation. Thrombocythemia, also called thrombocytosis, is a myeloproliferative disorder that can be primary (an independently occurring disorder, also called essential or idiopathic thrombocythemia) or secondary (a consequence of other health conditions or splenectomy). Doctors do not […]

Hemophilia Disease – Symptoms and Treatment

Definition of Hemophilia A group of inherited genetic disorders in which certain clotting factors are deficient or absent, resulting in clotting dysfunction. People who have hemophilia tend to bleed easily and longer than normal. Some forms of hemophilia carry substantial risk for life-threatening hemorrhage (bleeding). Types of Hemophilia Doctors classify hemophilia according to the deficient clotting factor, which may […]

Von Willebrand’s Disease – Symptoms and Treatment

Definition of Von Willebrand’s Disease A hereditary, genetic bleeding disorder resulting from a deficiency or molecular abnormality of clotting factor VIII. Unlike hemophilia A, which also results from clotting factor VIII deficiency, von Willebrand’s disease affects both men and women equally. Its inheritance pattern is autosomal dominant, meaning a child can acquire the condition when […]

Leukopenia – Symptoms, Causes and Treatment

Causes of Leukopenia, Symptoms and Treatment A decline in the number of leukocytes (white blood cells) circulating in the blood to fewer than 4,000 leukocytes per microliter of whole blood. The most common manifestation of leukopenia is neutropenia, a shortage of granulocytes called neutrophils. Most leukopenia is secondary to other health conditions a person may have, […]

Lymphadenitis – Definition and Symptoms

Definition of Lymphadenitis Lymphadenitis – inflammation or infection of lymph nodes. Lymphadenitis characterizes systemic infections such as infectious mononucleosis and regional infections such as sexually transmitted diseases (STDS). It may affect any lymph nodes in the body though is most noticeable when it affects lymph node clusters near the surface of the skin, such as in the neck, axillae (underarms), and […]
