What is myelitis What is myelitis?

Who knows, I guess not.

Myelitis refers to an inflammatory lesion of the gray or white matter of the spinal cord caused by infection by infection with a pathogen such as a virus, bacteria, etc. The main clinical manifestations are bilateral or unilateral numbness and weakness of the lower limbs, pain in the corresponding parts, movement disorders and sensory loss, and even urinary retention, paralysis and other manifestations, which can be accompanied by fever and other systemic symptoms. **Mainly anti-infection and enhance immunity, strengthen nutritional support**.

After the condition is stabilized, if there is a limb mobility disorder, ** training can be carried out to promote the recovery of limb function.

Myelitis is caused by infection with viruses, bacteria, spirochetes, rickettsia, parasites, protozoa, mycoplasma, or inflammatory lesions of gray matter and/or white matter caused by infection, with paralysis of the lower limbs, sensory deficits, and autonomic dysfunction as its clinical features. Common myelitis include purulent myelitis, acute myelitis, acute disseminated encephalomyelitis, subacute necrotizing myelitis, acute necrotizing hemorrhagic encephalomyelitis, pediatric acute disseminated encephalomyelitis, tuberculous myelitis, etc.

Myelitis refers to inflammatory lesions of gray matter and/or white matter caused by infection with viruses, bacteria, spirochetes, rickettsia, parasites, protozoa, mycoplasma, etc., or by infection, with paralysis of the lower limbs, sensory impairment, and autonomic dysfunction as its clinical features.

Common myelitis include suppurative myelitis, acute myelitis, pediatric acute disseminated encephalomyelitis, tuberculous myelitis, etc. Pediatric acute disseminated encephalomyelitis is a dangerous condition, with acute onset 1 2 weeks after infection or vaccination, mostly sporadic, non-seasonal, common 2 to 4 days after rash, patients often have sudden high fever, seizures, lethargy and deep coma when the rash is subsiding and the symptoms are improving. Therefore, children with myelitis should be actively seen by the doctor.

What are the symptoms of myelitis?

1.Dyskinesias: spinal shock is common in the early stages, presenting as paraplegia.

Limb and tone are low, tendon reflexes are absent, and pathological signs are absent. The shock period is usually 2-4 weeks or longer, and the spinal cord injury is severe. Longer in patients with complications of pulmonary urinary tract infections and bedsores.

During the recovery period, muscle tone gradually increases, tendon reflexes become hyperreflexes, pathological signs appear, and limb muscle strength gradually recovers from the distal end.

2.Sensory disturbances: loss of all sensation below the lesion ganglia. There may be hyperesthesia or banded paresthesias at the upper border of the sensory loss level. As the condition recovers, the sensory plane gradually decreases, but the recovery is slower than motor function.

3.Autonomic dysfunction: early urinary retention, no feeling of bladder fullness, no tension neurogenic bladder, overfilling of the bladder, filling incontinence; As spinal cord function is restored, the bladder capacity decreases, and when the urine fills to 300-400 ml, it urins spontaneously, which is called reflex neurogenic bladder.

No or little sweating below the level of injury. **Desquamation and edema. The stent is fragile and hyperkeratinized.

4.Acute ascending myelitis: the lesion rises rapidly within a few hours or 1-2 days, and the lower extremities rapidly affect the upper extremities or bulbar innervating muscles, resulting in dysphagia, dysarthria, paralysis of the respiratory muscles, and even death.

5.Demyelinating myelitis is more likely to be acute multiple sclerosis (MS) spinal type: the clinical presentation is similar to that of post-infectious myelitis, but progression is slow, often peaking within 1 to 3 weeks. Anterior infection is not obvious, and it is usually incomplete transverse lesions, which manifests.

1. Weakness or paralysis of the lower limbs on both sides, accompanied by numbness, the level of sensory impairment is not obvious or there are two planes, and urine and fecal disorders. Induced potentials and MRI may reveal lesions elsewhere in the CNS.

Myelitis is an inflammatory lesion of the spinal cord caused by infection or immune response, including bacterial, viral, fungal and other infections, as well as immune responses to nerve tissues.

Analysis: The typical clinical symptoms of myelitis are movement disorders, sensory disorders and autonomic dysfunction. If you do not actively accept regular ** in time, the injury and inflammation of the spinal cord may be aggravated and spread, leaving sequelae and even paralysis.

1. Sensory impairment: all the depth and shallowness of sensation below the lesion segment are lost, and there may be a sensory hypersensitivity area or band-like abnormality at the upper edge of the sensory loss, and with the recovery of the disease, the sensory plane gradually decreases, but the recovery of sensation is slower than that of movement, and it is not obvious. In some patients, sensory and motor symptoms gradually increase after the onset of the disease, even affecting the medulla oblongata, which is called ascending myelitis.

2. Movement disorders:

1) Acute onset, rapid progression, early spinal shock, manifested as quadriplegia or flaccid paralysis of both lower limbs, hypotonia, loss of tendon reflexes, negative pathological signs, patients often complain of inability to complete certain movements, such as upper limb weakness can not hold objects firmly, weakness of arms and difficulty in buttoning clothes.

2) Weakness of the lower limbs manifests as toe mopping, difficulty in going up and down stairs and sitting up. The spinal shock phase can last for 3-4 weeks.

3) After the spinal shock period, muscle strength begins to recover from the distal end, the pyramidal tract sign below the injured segment is positive, muscle tone and tendon reflexes gradually recover, and patients often complain of fatigue, stiffness of the lower limbs or clumsiness of movement when walking. Severe spinal cord injury often results in increased flexor muscle tone.

3. Autonomic dysfunction: urinary and fecal dysfunction, manifested as urinary retention, overfilling of the bladder, and filling incontinence; Fecal incontinence or constipation. Below the level of the lesion ** dry, no sweat, brittle nails.

Generally speaking, myelitis is an autoimmune reaction caused by infection, and the autoimmune response is dysfunctional after infection, producing some abnormal inflammatory cells and antibodies, thereby destroying the spinal cord and leading to the clinical manifestations of myelitis. So, essentially, it's a non-specific inflammatory response.

The onset of the disease is acute, and there may be a history of diarrhea or upper respiratory tract infections before the onset of the disease. The patient rapidly develops paralysis of the limbs, and paraplegia of both lower limbs is more common, and bilateral paralysis is more symmetrical. There is also usually marked sensory deficits, loss of sensation below the lesion segment, autonomic dysfunction, urinary retention, and even intestinal obstruction.

Most patients respond to glucocorticoids**.

It's a terrible disease, it's a terrible disease, and this thing can't be a**.

Osteomyelitis is a serious disease. It can cause multi-organ failure, which must be early**.

Myelitis is a condition caused by infection or toxins that invade the spinal cord. Acute myelitis caused by viral infection usually occurs in young adults. The exact shape of myelitis is not yet known.

Myelitis is mostly an autoimmune reaction caused by a viral infection, or an inflammation of the spinal cord caused by poisoning, allergies, etc. Its pathogens mainly include influenza virus, herpes zoster virus, rabies virus, poliovirus, etc.

Myelitis may be caused by a viral infection, or by a bacterial or parasitic infection, which may cause numbness in the legs, weakness, difficulty eating, slurred speech, and severe fever.

What are the specific harms of myelitis to the body?

First, myelitis can cause paralysis, usually paraplegia, which is usually a common manifestation of weakness in both lower limbs. In severe cases, patients need to be bedridden and unable to stand or walk on their own. If the myelitis involves a relatively upward segment that affects the cervical spinal cord, the patient may even develop quadriplegia and respiratory dysfunction, which can be life-threatening due to respiratory failure.

Second, patients with myelitis usually have significant sensory disturbances, unable to feel pain below the level of spinal cord injury, and unable to feel temperature sensation.

Third, there will be bowel and urine dysfunction, such as intestinal obstruction, urinary retention, etc. In addition, if patients with myelitis are bedridden, they will also have complications such as lung infection, urinary tract infection, and deep vein thrombosis of the lower limbs.

The more common ones are transverse myelitis, which is more common in adolescents and is caused by a viral infection. Symptoms of myelitis are often mild, such as low-grade fever, general malaise, or upper respiratory tract infection.

Myelitis mostly occurs after infection, such as infection with viruses, bacteria, spirochetes, rickettsia, parasites, protozoa, mycoplasma and other pathogens, and mycoplasma is mostly an autoimmune reaction caused by viral infection, which is still unclear.

The clinical manifestations are acute onset, with low-grade fever, radicular pain at the lesion site, numbness and weakness of the limbs, and a sense of banding at the lesion segment. Paralysis can also occur without any other symptoms. Most of them appear within a few hours or days of movement impairment below the level of involvement, sensory loss, and bladder and rectal sphincter dysfunction, and the early stage of movement disorder is a manifestation of spinal cord shock, which generally lasts for 2 to 4 weeks, and the muscle tone gradually increases, the tendon reflex is active, and pathological reflexes appear.
