What is dermatomyosis? How this disease develops, what is its symptoms? The author of this article knows the answers to these questions.
Content
Dermatomiositis (polyimiosit) is a systemic disease of the skeletal and smooth muscles and skin. Presumable cause of disease - viral.
Provoke the disease following factors:
- cooling,
- Long stay in the sun,
- pregnancy,
- Rembossing drugs.
In 20-30% of cases, dermatomyositis is observed in patients with various tumors.
Mechanism for the development of the disease - violations in immune status. Women are 2 times more often than men, with two age peaks (transitional age, period of clicks). Perfect family-genetic predisposition.
Signs of dermatomyositis
The disease begins more or less acute with muscle lesion (muscle weakness, muscle pain), joint pain, body temperature, skin lesions (diverse rash, itching, spotted redness, increased energization, reinforced or sharply reduced pigmentation, calcium deposition in thicker skin or subcutaneous fluid), dense common swelling.
In the future, the disease acquires a recurrent flow. The defeat of skeletal muscles is progressing - they are painful when moving and alone, pain is enhanced by pressing on them, muscle weakness increases. The muscles of the shoulder and pelvic belt are compacted, increase in volume, their active movements are disturbed, patients can not sit on their own, lift the head from the pillow.
The defeat of the mimic muscles leads to the masca of the face, pharynses and respiratoryness - to the disorders of swallowing and respiration, which is also complicated by frequent pneumonia. If the eye muscles are affected, there are two-sided twinings in the eyes, strabismus, bilateral ptosis (upper eyelid).
Involvement in the muscle process of the heart (myocarditis or myocardidididium) is manifested by the resistant increase in the pulse, a decrease in pressure, the appearance of systolic noise, can lead to the development of heart failure. In a third of the patients - Riino syndrome (whitewashing and the formation of the fingers of the hands during cooling). Reduced or no appetite, there are abdominal pain, gastrointestinal bleeding, intestinal obstruction can develop.
Select 3 forms of dermatomyositis flow:
- acute with the rapid development of symptoms (can end with death after 36 months. due to severe loss and cardiovascular system);
- subacute;
- Chronic.
Recognition is carried out on the basis of biochemical analysis of blood and urine, but the main role belongs to the detection of specific changes in the biopic muscle.
