in children is most common hemorrhagic vasculitis Vasculitis - when blood vessels refuse to work (kapillyarotoksikoz's disease, Henoch - Schonlein purpura).In addition, they can d
sometimes found in children and other vasculitis: Wegener's granulomatosis, Chardjui-Strauss syndrome, Behcet's syndrome.
Kawasaki syndrome in children
Kawasaki syndrome or mucous - kozhnozhelezisty syndrome - a disease peculiar to young children.This affects the walls of medium-sized blood vessels.Specific manifestations of this disease are a rash, fever and inflammation of the lymph nodes.Kawasaki syndrome may be complicated by inflammation of the joints and the heart.
Why is this disease begins in children.Today, no one knows.It is possible that a precipitating factor is a viral disease.More common in boys aged from a few months to four or five years, but the disease is found in teens and adults.There are family history of the disease, suggesting a hereditary factor.

polyarteritis nodosa in children
polyarteritis nodosa (knotty periarteritis) - a disease in which the inflammatory process is developing in the walls of the small and medium-sized arteries.In the affected artery aneurysm formation (expansion thinning of the arterial wall).The aneurysms there is stagnation of blood to form clots that clog the vessel lumen, disrupting the blood supply to an organ.
believed that the starting point for the onset of the disease can be vaccinated, drugs, viruses causing chronic hepatitis Hepatitis - the scourge of our time , as well as other viral infections.Also, it matters that a child of any allergies.
disease begins acutely with high fever, muscle-joint pain (pain and swelling of the joints, pain in the calf muscles), rash.The temperature then rises to very high numbers, then falls, which is accompanied by drenching sweat.Very fast depletion occurs, the child loses a significant body weight.The skin appears bluish rash characteristic of marbling or tree branches.They can be very bright, but then gradually fade.Furthermore, there nodular rash.
thrombosis occurs when blood vessels in the skin and mucous membranes, which may be accompanied by the emergence of areas of necrosis (tissue necrosis) with subsequent ulceration.
central nervous system causing severe headaches, vomiting, and sometimes convulsions, visual disturbances.With the defeat of the gastrointestinal tract nausea, vomiting, severe abdominal pain paroxysmal Abdominal pain: Types and Symptoms .Such lesions may be complicated by rupture of the intestinal wall and peritonitis.It is also possible kidney damage in the form of glomerulonephritis and cardiac complications.
nonspecific aortoarteriit children
nonspecific aortoarteriit (Takayasu's disease, pulseless disease) - manifested in defeat large blood vessel - the aorta and its branches, which results in impaired blood supply to various organs, including the absence of a pulse.This disease is more common in girls aged 10 to 15 years, but it also occurs in preschool children, and the case for its more severe.
Takayasu's disease can be complicated by aneurysm thoracic and abdominal aorta and coronary vessels of the heart to slow its progressive occlusion (decrease in lumen) that gives rise to attacks of angina and myocardial infarction.
Vasculitis in children is more severe and require timely and appropriate medical care.
