Inflammation of the spinal cord. M. may be Acute or Chronic. It is called Transverse when it affects the whole thickness of the cord through a moderate part of its length; Diffuse when it affects a considerable extent of the cord vertically; Focal when it attacks a single small spot; Disseminated when it attacks several scattered spots; Central when it affects the gray matter about the central canal; Cornual when it affects the horns (especially the anterior horns) of gray matter (Cf. Poliomyelitis). When the inflammation begins or is most pronounced in the nervous substance, the m. is called Parenchymatous; when the neuroglia is primarily attacked, so that there is great increase of the interstitial substance and consequent atrophy of the nervous tissue, the m. is called Interstitial or Sclerosing (see Sclerosis). The m. is said to be Ascending or Descending according as the inflammation progresses upward or downward from the original point of attack. M. is also named according to its CAUSATION, as Compression m., Concussion m., Traumatic m., etc.; and according to the ATTENDANT PATHOLOGICAL PHENOMENA, as Haemorrhagic m. (m. accompanied by haemorrhage into the substance of the cord) and Cavitary m. (m. with the formation of cavities in the cord due to disintegration of the inflammatory products). The SYMPTOMS of m. depend upon the site and extent of the lesion, and comprise sensory disturbances (pain in the back, a girdle feeling or sensation of a cord being tied about the body at the site of the lesion, hyperaesthesia, formication and other dysaesthesiae, and anaesthesia in the parts of the body supplied by the portion of the cord below the lesion); motor disturbances (paraplegia); alteration (usually exaltation) of the reflexes; paralysis of the sphincters, producing incontinence of feces and retention and afterward incontinence of urine, with resulting cystitis; trophic disturbances, especially bed-sores; and in the later stages spastic contraction of the paralyzed limbs. TREATMENT: dry or wet cups, counter-irritation, and cold over spine; ergot, mercury, and potassium iodide internally; protection of the skin from pressure and irritation; regular catheterism of the bladder, and in case of cystitis irrigation with antiseptic solutions.
