Sickle Cell Anemia
Sickle cell disease (SCD) is a group of blood disorders typically inherited from a person's parents. The most common type is known as sickle cell anaemia. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances. Problems in sickle cell disease typically begin around 5 to 6 months of age. A number of health problems may develop, such as attacks of pain (known as a sickle cell crisis), anemia, swelling in the hands and feet, bacterial infections and stroke. Long-term pain may develop as people get older. The average life expectancy in the developed world is 40 to 60 years. Sickle cell disease occurs when a person inherits two abnormal copies of the β-globin gene (''HBB'') that makes haemoglobin, one from each parent. This gene occurs in chromosome 11. Several subtypes exist, depending on the exact mutation in each haemoglobin gene. An attack can be set off by tempera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congenital Hemolytic Anemia
Congenital hemolytic anemia refers to hemolytic anemia which is primarily due to congenital disorders. Types Basically classified by causative mechanism, types of congenital hemolytic anemia include: * Genetic conditions of RBC Membrane ** Hereditary spherocytosis ** Hereditary elliptocytosis * Genetic conditions of RBC metabolism (enzyme defects). This group is sometimes called ''congenital nonspherocytic (hemolytic) anemia'', which is a term for a congenital hemolytic anemia without spherocytosis, and usually excluding hemoglobin abnormalities as well, but rather encompassing defects of glycolysis in the erythrocyte.medconditions.net > Hemolytic Congenital, Nonspherocytic Anemia Definition Retrieved April 15, 2011 ** Glucose-6-phosphate dehydrogenase deficiency (G6PD or favism) ** Pyruvate kinase deficiency ** Aldolase A deficiency * Hemoglobinopathies/genetic conditions of hemoglobin ** Sickle cell anemia ** Congenital dyserythropoietic anemia ** Thalassemia See also * Hemat ...

Polycythemia Vera
Polycythemia vera is an uncommon myeloproliferative neoplasm (a type of chronic leukemia) in which the bone marrow makes too many red blood cells. It may also result in the overproduction of white blood cells and platelets. Most of the health concerns associated with polycythemia vera are caused by the blood being thicker as a result of the increased red blood cells. It is more common in the elderly and may be symptomatic or asymptomatic. Common signs and symptoms include itching (pruritus), and severe burning pain in the hands or feet that is usually accompanied by a reddish or bluish coloration of the skin. Patients with polycythemia vera are more likely to have gouty arthritis. Treatment consists primarily of phlebotomy. Signs and symptoms People with polycythemia vera can be asymptomatic. A classic symptom of polycythemia vera is pruritus or itching, particularly after exposure to warm water (such as when taking a bath), which may be due to abnormal histamine release o ...

Thrombocytopenic Purpura
Thrombocytopenic purpura are purpura associated with a reduction in circulating blood platelets which can result from a variety of causes, such as kaposi sarcoma. Types By tradition, the term idiopathic thrombocytopenic purpura is used when the cause is idiopathic. However, most cases are now considered to be immune-mediated. Another form is thrombotic thrombocytopenic purpura. Diagnosis Diagnosis is done by the help of symptoms and only blood count abnormality is thrombocytopenia. Treatment See also * Aspirin * Hematopoietic ulcer * Thrombocyte Platelets, also called thrombocytes (from Greek θρόμβος, "clot" and κύτος, "cell"), are a component of blood whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby ini ...

Macroglobulinemia
Macroglobulinemia is the presence of increased levels of macroglobulins in the circulating blood. It is a plasma cell dyscrasia, resembling leukemia, with cells of lymphocytic, plasmacytic, or intermediate morphology, which secrete a monoclonal immunoglobulin M component. There is diffuse infiltration by the malignant cells of the bone marrow and also, in many cases, of the spleen, liver, or lymph nodes. The circulating macroglobulin can produce symptoms of hyperviscosity syndrome: weakness, fatigue, bleeding disorders, and visual disturbances. Peak incidence of macroglobulinemia is in the sixth and seventh decades of life. (Dorland, 28th ed) See also * Waldenström macroglobulinemia Waldenström macroglobulinemia () is a type of cancer affecting two types of B cells: lymphoplasmacytoid cells and plasma cells. Both cell types are white blood cells. It is characterized by having high levels of a circulating antibody, immunoglo ... * Hematopoietic ulcer References External li ...

Cryoglobulinemia
Cryoglobulinemia is a medical condition in which the blood contains large amounts of pathological cold sensitive antibodies called cryoglobulins – proteins (mostly immunoglobulins themselves) that become insoluble at reduced temperatures. This should be contrasted with cold agglutinins, which cause agglutination of red blood cells. Cryoglobulins typically precipitate (clumps together) at temperatures below normal body temperatureand will dissolve again if the blood is heated. The precipitated clump can block blood vessels and cause toes and fingers to become gangrenous. While this disease is commonly referred to as cryoglobulinemia in the medical literature, it is better termed cryoglobulinemic disease for two reasons: 1) cryoglobulinemia is also used to indicate the circulation of (usually low levels of) cryoglobulins in the absence of any symptoms or disease and 2) healthy individuals can develop transient asymptomatic cryoglobulinemia following certain infections.

Skin Lesion
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions resul ...
