Polymyositis.

is an inflammatory myopathy, which is a group of muscle diseases that involve inflammation of the muscles or related tissues, such as the blood vessels of the muscles. In most cases, polymyositis is not clear that for some reason the body's immune system.

It reverses its own muscles and damages muscle tissue during autoimmune processes.

In polymyositis, inflammatory cells of the immune system directly attack muscle fibers.

The diagnostic criteria for polymyositis are simple, i.e., three out of four, and polymyositis is often accompanied by dermatomyositis.

So let's also talk about the diagnostic criteria for dermatomyositis. First of all, the diagnostic criteria for dermatomyositis are four three, that is, three of the four diagnostic bases need to occupy three to confirm the diagnosis. The details are as follows:

1. The clinical manifestations are symmetrical proximal muscle weakness and pain; Clause.

2. Elevated kinase profile. Clause.

3. Do electromyography.

After the examination and electromyography are detected, it is myogenic injury; Clause.

Fourth, the patient's weakest muscles are taken down for pathology, which is the striated muscle.

of injuries. If you have three of these four criteria, you can diagnose polymyositis.

The diagnosis of dermatomyositis is that if the patient has ** changes, plus three of the previous four, it is diagnosed as dermatomyositis. The longer the clinical work, the more you will understand the diagnosis. For example, there was a farmer who had a history of recent weight loss, symmetrical muscle weakness and pain, and high kinases, and his performance was atypical when he did electromyography, and he needed to do pathology, but this patient was more afraid after hearing about pathology, so he did not do it.

Later, he was given hormones and slow-acting drugs to him**, but the patient came back half a year later with a pale face, considering that the patient must have some other problems. At that time, the tumor was excluded and no tumor was found, but when he came back for treatment half a year later, the patient had a lung mass. Therefore, when diagnosing polymyositis, there are three out of four, and one cannot be missing.

If it is examined to belong to multiple myositis injuries, this still needs to be actively hospitalized**, this disease, this period of time will be very poor, if not timely ** and control the condition, it is very likely to lead to because of respiratory muscles.

Paralysis in turn causes a serious risk of breathing, difficulty and suffocation. and, if necessary, may also require tracheostomy salvage**.

There will be difficulty swallowing, and the respiratory muscles will be very weak, there will be problems with the muscle biopsy, the muscle enzyme profile will be elevated, and so on.

The criterion for diagnosis is to report accordingly, and the second is to look at your symptoms. If there is some muscle weakness or some muscles are particularly painful, there will also be some necrosis and degeneration. Then it means that it is this disease.

The criterion is that there is muscle weakness, very soreness, and all indicators are low, such as the upper limbs are difficult to lift, or the lower limbs are unable to move, which is the standard, and it can be judged as myositis.

Myositis is judged by blood tests that show abnormally high levels of muscle enzymes; Myositis is an inflammatory muscle disease that causes muscle weakness, if there is muscle soreness and muscle weakness, you need to go to the hospital immediately for a specific examination and timely examination.

Doctors may diagnose myositis based on symptoms of muscle weakness or other symptoms of myositis. Tests for myositis include: blood tests:

High levels of muscle enzymes, such as creatine kinase, can mean inflammation in the muscles. Other blood tests can detect autoimmune diseases by checking for abnormal antibodies.

Diagnostic criteria for polymyositis and dermatomyositis include:

First, ** symptoms. Purplish-red edematous erythema appears on the face, especially on the eyelids, chest, and extensor extremities, often accompanied by telangiectasia, hyperpigmentation, or atrophy.

Second, muscle symptoms. Pain and tenderness in the proximal limbs and other muscles, weakness or atrophy, difficulty in moving, irregular fever and arthralgia in the limit period.

Third, urine creatine, phosphocreatine kinase, and aldolase are elevated.

Fourth, myogenic changes in electromyography.

Fifth, histopathological changes such as hyaline changes, collagen fiber hyperplasia, muscle fiber atrophy and degeneration, transverse striation disappearance, and inflammatory cell infiltration in the interstitium.

The assessment criterion is that any of the first two of the five items on appeal plus the last three can be confirmed. Possession of the first and any other is suspicious.
