Spinal cord injury

Introduction Spinal cord traverse damage The spinal cord dysfunction caused by infection or infection-induced spinal cord dysfunction leads to nerve impulse blockade of all or most of the nerve bundles, limited to several segments of acute transverse spinal cord inflammation. Most are ill after acute infection or vaccination. It is characterized by paralysis of the limbs below the level of spinal cord lesions, loss of sensation and dysfunction of the bladder, rectum and autonomic nerves. It is one of the common spinal diseases. The onset can be seen in any season, but it is more common in late winter and early spring and late autumn and early winter.

Cause

1. Infection 20% to 40% caused by viral infection. Most common in herpes simplex virus type 2, varicella-zoster virus and enterovirus. In recent years, myelopathy associated with HIV-1 and human (tropic) T lymphocyte virus type I (HTLV-1) has begun to receive attention.

2. Vascular disease Myelitis caused by spinal cord blood supply disorders is also known as acute necrotizing myelitis. Vascular lesions secondary to connective tissue diseases, sarcoidosis, malignant tumors, infections, etc. are common.

3. Demyelinating diseases such as multiple sclerosis (MS) and acute disseminated encephalomyelitis associated with demyelinating diseases may be the first symptom of acute transverse spinal cord injury.

4. Primary refers to non-specific acute spinal cord injury of unknown cause, which may be induced by overwork and spinal trauma. Some patients have upper respiratory tract infection, diarrhea or vaccination history 1 to 2 weeks before the disease.

(1) More common in young and middle-aged, scattered disease.

(2) First symptoms of infection, followed by acute onset.

(3) Rapid development of transverse spinal cord damage.

(4) Examination of cerebrospinal fluid: normal pressure, colorless and transparent appearance, slight increase in cell number and protein, normal sugar and chloride. Individual acute phase may have vertebral management obstruction.

Differential diagnosis

(1) According to the history of the disease, paraplegia, early dysfunction of the two stools, and the disease has nothing to do with the meal, and differentiated from periodic paralysis.

(2) According to the symptoms of the pioneer, the onset of the disease, the signs of the nervous system and laboratory tests, and the identification of acute infectious polyneuritis.

(3) According to whether it is accompanied by symptoms of optic nerve or central nervous system damage and recurrent characteristics, it is differentiated from multiple sclerosis.

(4) should also pay attention to the differentiation of spinal cord compression, such as spinal hemorrhage, spinal tuberculosis, cancer metastasis, and epidural abscess.
