Caseous lymphadenitis (CLA) is an infectious disease caused by the bacterium Corynebacterium pseudotuberculosis, that affects the lymphatic system, resulting in abscesses in the lymph nodes and internal organs.
As clotting factors and platelets are used up, bleeding may occur. [1] This may include blood in the urine, blood in the stool, or bleeding into the skin. [1] Complications may include organ failure. [2] Relatively common causes include sepsis, surgery, major trauma, cancer, and complications of pregnancy. [1]
Traumatic bleeding is caused by some type of injury. There are different types of wounds which may cause traumatic bleeding. These include: Abrasion — Also called a graze, this is caused by transverse action of a foreign object against the skin, and usually does not penetrate below the epidermis.
While the exact cause of CLL is unknown, having a family member with CLL increases one's risk of developing the disease. [10] [4] Environmental risk factors include exposure to Agent Orange, ionizing radiation, and certain insecticides. [12] [4] The use of tobacco has also associated with an increased risk of having CLL. [10]
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
Splinter hemorrhages (or haemorrhages) are tiny blood clots that tend to run vertically under the nails.Splinter hemorrhages are not specific to any particular condition, and can be associated with subacute infective endocarditis, scleroderma, trichinosis, systemic lupus erythematosus (SLE), rheumatoid arthritis, psoriatic nails, [1] antiphospholipid syndrome, [2]: 659 haematological ...
Other causes of splenomegaly (for example, Gaucher disease or hemoglobinopathies) can also predispose to infarction. Splenic infarction can also result from a sickle cell crisis in patients with sickle cell anemia. Both splenomegaly and a tendency towards clot formation feature in this condition.
The condition therefore may cause pathological bleeding and/or thrombosis. [2] [3] [4] Acquired dysfibrinogenemia is a non-hereditary disorder in which fibrinogen is dysfunctional due to the presence of liver disease, autoimmune disease, a plasma cell dyscrasias, or certain cancers. It is associated primarily with pathological bleeding. [5]
