Acute Myelitis

Overview of acute myelitis of the spinal cord is a non-specific inflammatory disease, the infection occurred after the Inflammation often involving several segments of the pulp stages in and around the meninges. and spinal cord involvement and the most vulnerable to cross-cutting have symptoms of spinal cord damage. After the onset of some patients, paralysis and sensory dysfunction of the average water rising eventually even affect the upper cervical spine caused paralysis of the limbs and respiratory muscle paralysis, with high fever may endanger lives and safety of patients, called ascending myelitis, on the following major acute transverse myelitis. Etiopathologic etiology remains unclear, as some may be caused by infection, or an infection after the body's own immune reaction. Some occurred after vaccination. Inflammation can affect different parts of the spinal cord, but above the spinal cord up to see. Lesions in the spinal cord swelling and hyperemia, soften, soft congestive meningocele, turbidity, spinal plane stages boundaries unclear. Visibility point bleeding. Endoscopic see soft congestive meningocele and inflammatory cell infiltration. Serious spinal softening, necrosis, the late spinal cord can atrophy and scar formation. Clinical manifestations in adults styles. Disease or a few days before a two-week may have a fever, general malaise, or upper respiratory tract infection history. Rapid onset, often first back pain or chest waist band flu, followed by numbness and weakness and other symptoms. more than a few hours to several days to develop symptoms peak, there transverse spinal cord damage symptoms. 1, movement disorders : a spinal cord injury after paraplegia caused by the most common, such as spinal cord damage occurs tetraplegic. may accompanied by paralysis of respiratory muscles. Spinal shock early stage disease was below flaccid paralysis, muscular tension reduction, deep reflection disappeared, pathological reflex may also cited disagree. Usually in two-three weeks, a gradual transition to spastic paralysis, muscular tension gradually increased, particularly over extensor Tension increased significantly, Deep reflection then there hyperthyroidism, pathological reflex obvious, sometimes muscle strength may also have begun to resume, resume ordinary needs for weeks, months, but eventually some signs often residues. If the lesion heavy, with a wide range of merger or a urinary tract infection and other complications, spinal shock phase may be extended, Some of the long-term performance of flaccid paralysis, or spinal shock after the passage of spastic paralysis buckling limbs, At this point limb flexor tension increased, a slight stimulation, legs buckling cramps, with sweating, Vertical hair automatic responses and urine discharge and other symptoms, as a whole spinal reflex. Standing above indicate a poor prognosis, some patients can be paralyzed for life maimed. 2, sensory dysfunction : Plane damage following limbs and torso are feeling the various obstacles, severe completely disappeared, Double-thalamus and spinal cord after cable damage caused. The perceived lack geopolitical zones have a feeling with allergies. 3, autonomic obstacle : spinal shock, spinal cord and central voiding reflex function to be restrained voiding dysfunction, urinary retention and urinary bladder filling right without any feeling of detrusor relaxation and tension was lost bladder, Urine capacity of up to 1000 ml or more. When overactive bladder filling, was involuntary urine to leak out, filling is called urinary incontinence. When the spinal cord after a period of shock, spinal cord micturition center lost brain inhibitory control, voiding hyperreflexia, Few within the bladder urine can be caused detrusor contraction and involuntary urination, to be called the reflex incontinence. If lesions continuing improvement can be gradual recovery arbitrarily voiding ability. In addition, spinal shock still Constipation, the following physical damage to plane without Khan or less Khan, dry skin, pale and cold, Li Mao could not muscle contraction; After the shock, skin sweating and skin temperature can be improved, Li Mao may also enhance reflection. If cervical lesions affecting the spinal center ciliary offal may arise Horner levy. 4, laboratory examinations : acute phase of the total peripheral blood leukocytes may be slightly higher. CSF pressure normal, with the exception of severe swelling of the spinal cord, spinal without obstruction general phenomenon. CSF total cells, especially of lymphocytes and protein content can be increased to varying degrees, it can be normal. CSF immunoglobulin content can also be abnormal.
