Symptoms.—These depend upon the location of the inflammation and the severity. The onset may be sudden or gradual—when it is sudden, there may be a chill followed by a fever of 101 to 103 degrees—general feeling of illness, loss of appetite, with coated tongue and constipation. There may be over-sensitiveness to pain and touch. Pain may radiate from the back into the limbs, with numbing and tingling of the limbs. The urine may be retained or may dribble away. Usually there is obstinate constipation. There is frequently the feeling of a band around the body. Paralysis may follow in the lower extremities and higher up, sometimes, depending upon how high up in the cord the inflammation exists. This paralysis may cause no motion of the limbs or produce an exaggerated contracting of the affected muscles, the knees being drawn up on the abdomen and the heels touching the buttocks.
[NERVOUS DISEASES 305]
Recovery.—Chances for recovery depend upon the cause. Most cases are chronic and may last for years.
Treatment.—Treatment depends also upon the cause. Rest in bed; counter-irritation, wet cupping, with care on account of bed sores. A water-bed from the first may prevent bed-sores. The urine must be drawn if it is retained. The medical treatment must be carefully given and a physician of experience should be obtained.
LOCOMOTOR ATAXIA. Tabes dorsalis. Posterior Spinal Sclerosis).—A hardening (sclerosis) affecting the posterior parts of the spinal cord and characterized by incoordination, which means a condition where a person is unable to produce voluntary muscular movements; for instance, of the legs, etc., loss of deep reflexes to bend them back; disturbances of nutrition and sensation, and various affections of sight.
Causes.—This is a disease of adult life, persons under twenty-five being rarely affected, and is more common in men than women (ten to one). Sometimes children suffering from hereditary syphilis have it. The chief predisposing cause is syphilis which precedes it in from seventy to eighty-five of the cases according to various authorities. Exposure to cold and wet, sexual and alcoholic excesses, mineral poisoning, and great physical exertion also exciting causes.
Symptoms.—These are numerous. They appear in succession and with the same regularity.
Stages.—Stages of pain; the stage of ataxia, peculiar gait; and the state of paralysis.
1. Prodromal or forerunning; the stage of pain.—This consists of lightning-like pains in the lower extremities, numbness, formication (feeling of ants, etc., crawling), sensation of dead extremities; pins and needles in the soles of the feet and fingers, coldness, itching of arms and scrotum or other parts, a sensation of constriction around the chest, headache, pain in the small of the back and loins of an aching character may occur. These symptoms may constitute the only evidence of locomotor ataxia and last for years; but sooner or later there are added absence of knee cap bone reflex (knee jerk), and immobility of the pupil. The loss of the knee jerk is always observed in time. The pupil fails to respond to light while it still accommodates for distance, called Argyll Roberston pupil. There may be imperfect control of the bladder with slow, dripping or hasty urination. Later the control is not imperfect, but it may be painful. Inflammation of the bladder may occur which is dangerous. There is usually obstinate constipation and loss of sexual power. These symptoms may last for several months and years, and then the second stage symptoms appear.
