What are the diagnostic criteria for myositis? What should I pay attention to?

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.

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 also known as neurological muscle inflammation, this inflammation will appear in many parts of the human body, when myositis occurs in the body, it will be manifested as pain, and there is a clear burning sensation. When this happens, the patient will experience weakness and even pain in the limbs, and their strength will be weakened. This condition usually occurs on the face, but also appears in the limbs, etc., and sometimes there is muscle atrophy, manifested as myasthenia gravis, difficulty going upstairs, slow movement, and the need for your own arms to relieve the situation.

In the early stage of neuromyositis, muscle lesions generally do not occur, and a small number of patients in the advanced stage will have symptoms of low tendon reflexes. When the patient suffers from myositis, he should pay attention to it in time, because at the beginning, he can only feel his muscle strength weakened, and sometimes there will be a certain amount of pain in the limbs, but most of the cases are not very common, and a small number of people will have this obvious pain. In the early stage, you should go to the hospital in time**, otherwise, there may be atrophy in the late stage of myositis, and more serious things will happen.

Patients with myositis should be treated in time to ensure that they can recover their health before, once the muscles atrophy, then it will cause great inconvenience in their own lives, and it will also cause difficulties in taking care of themselves, and family members are needed to help patients to live. Patients in the early stage of myositis should never ignore its importance, so as not to cause serious problems that will lead to the patient's inability to move freely in later life. During the examination in the hospital, the doctor usually needs to ask the patient to take a blood test to see what symptoms the patient's myositis has, and through the examination, it can be seen that the patient with myositis has significantly increased muscle enzymes.

Therefore, when carrying out the first time, it is necessary to follow the doctor's advice, eat reasonably, and at the same time, it is necessary to conduct a review every period to prevent some muscle atrophy. Patients must pay more attention to rest at ordinary times, this kind of patients with myositis are generally in a state of overwork, to eat some high-protein food, muscle replenishment is of great help to the condition.

There will be pain, which will affect the movement of the muscles, there will be weakness in the limbs, it will be very difficult to comb the hair, and the arms will not be able to lift up. Be sure to pay attention to your diet, see a doctor in time, find the root cause of the problem, and pay attention to rest, not too tired.

The early symptoms of myositis are muscle weakness, muscle pain, joint pain, Raynaud's phenomenon, and difficulty swallowing.

Proximal muscle weakness is the most obvious and typical symptom in the early stages of myositis, and patients have sudden muscle weakness that lasts for a long time.

Some patients have weakness in the shoulder girdle or pelvic girdle muscles, manifested by difficulty lifting their hands above their shoulders or climbing stairs, and patients are advised to stay in bed or use a wheelchair; If the throat muscles are affected, symptoms such as difficulty swallowing and breathing may occur.

The onset of myositis is relatively insidious, and patients mostly present with proximal muscle weakness, which is symmetrical, and painful when pressed; Other patients have atypical symptoms such as squatting, standing up suddenly, difficulty climbing stairs, fever, and joint pain.

1 Symmetrical proximal muscle weakness indicates: i.e., symmetrical weakness of the limb girdle and anterior cervical extensor muscles that persist for weeks to months, with or without esophageal or respiratory muscle involvement. , 2 Muscle Tests are very is:

Pathological examination of skeletal muscle muscle reminds of degeneration and necrosis of muscle fibers, cell phagocytosis, regeneration, basophilia, enlargement of the nuclear membrane, comparison of nucleoli, atrophy of the surrounding structure of the fascia, different sizes of fibers, and inflammatory exudation. , 3.Elevated serum muscle enzymes:

Serum skeletal muscle muscle enzymes such as creatine phosphokinase, aldolase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase are elevated. , 4 EMG showing myo-enforcing lesions: no triad changes on EMG:

Immediate limit of short, small multiphase hook potential; fibrillation potential, anti-sine wave; Insertional provocation and bizarre high-frequency discharges. , 5 Typical **Damages: Inclusive:

Positive rash: lilac eyelids, periorbital edema; Gottron's sign: erythematous squamous rash on the dorsum of the metacarpophalangeal joints and proximal interphalangeal joints.

An erythematous rash that presents on both knees, elbows, ankles, face, neck, and upper body. , Criteria:, Polymyositis:
