Splinter hemorrhages are tiny spots of blood seen underneath the fingernails or toenails. They are caused when tiny blood vessels (capillaries) in the nail bed rupture or burst. The name comes from the fact that the dark reddish-brown spot of blood often resembles a streak that looks like a splinter. The main cause of splinter hemorrhages is trauma or injury, but nail diseases or other diseases or conditions that affect the blood vessels can also cause them. Sometime taking certain medications, including nonsteroidal anti-inflammatory drugs (NSAIDs), warfarin (Coumadin), tetracycline, or ganciclovir (Cytovene), can cause splinter hemorrhages.

Causes of Splinter Hemorrhage
Antiphospholipid syndrome (phospholipid antibody syndrome or Hughes syndrome) is an immune system disorder with symptoms that include: excessive blood clotting, miscarriages unexplained fetal death, or premature birth. In antiphospholipid syndrome, these symptoms are accompanied by the presence of antiphospholipid antibodies (cardiolipin or lupus anticoagulant antibodies) in the blood. Treatment focuses on preventing clotting by thinning the blood with the use of anticoagulants and aspirin.
Diabetes (Type 1 and Type 2)
Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Drug addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Endocarditis, a serious infection of one of the four heart valves is caused by growth of bacteria on one of the heart valves; leading to an infected massed called a "vegetation." The infection can be caused by having bacteria in the bloodstream after dental work, colonoscopy, or other similar procedures. Endocarditis symptoms include: fever, fatigue, weakness, chills, aching muscles and joints, night sweats, edema in the legs, feet, or abdomen, malaise, shortness of breath and small skin lesions. Treatment for endocarditis is generally aggressive antibiotic treatment.
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include: Smoking High blood pressure High cholesterol Diabetes Family history Obesity Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.
Lupus (Systemic Lupus Erythematosus or SLE)
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).

Occurring as a result of spasm of blood vessels, the cause is unknown. Symptoms of Raynaud's phenomenon depend on the severity, frequency, and duration of the blood vessel spasm.

Vasculitis (Symptoms, Causes, Diagnosis, Treatment, Types)
Vasculitis (arteritis, angiitis) is a general term for a group of uncommon diseases which feature inflammation of the blood vessels. Each form of vasculitis has its own characteristic pattern of symptoms. The diagnosis of vasculitis is definitively established after a biopsy of involved tissue demonstrates the pattern of blood vessel inflammation. Treatment is directed toward decreasing the inflammation of the arteries and improving the function of affected organs.
