It is often very difficult to say whether a given case is one of chronic rheumatoid arthritis or of chronic gout; and there is no doubt that in England, where gout prevails, it is not unfrequently associated with rheumatoid arthritis, sometimes preceding and even causing it, much more often following it, for the one does not exclude the other.
While rheumatoid arthritis most frequently begins in the hand, and is usually symmetrical and bilateral, gout commonly begins in the lower extremities, and especially in the metatarsal joint of the great toe, and of one foot only. Chronic gout is far more frequently preceded by attacks of acute gout than chronic rheumatoid arthritis is by the acute form of that affection; a history of inherited predisposition, of indulgence in the use of wine, ale, porter, and of animal food, of deficient bodily exercise, with perhaps great mental occupation or anxiety, of recurring gouty dyspepsia or of a tendency to lithiasis, would indicate gout, while the absence of these and a history of frequent exposure to cold and wet, of injury to the joint, of previous exhausting disease or drain, of impaired health, debility, or poverty, would strongly imply rheumatoid arthritis. Gout is especially observed in males over thirty, and very rarely in children; general rheumatoid arthritis is chiefly a disease of females during menstrual life, and occasionally occurs in children of either sex.
The partial form is, like gout, chiefly a disease of men, but occurs generally at a more advanced age than gout. Even chronic gout is more or less paroxysmal, with distinct intermissions; chronic rheumatoid arthritis is more or less abiding and progressive, with only remissions in its course and severity; the former is frequently associated with chronic renal disease, the latter is not. The urate-of-soda deposits about the articulations in gout appear as more or less round or ovoid swellings in the close vicinity of the joints, but not observing their exact level or their general form; softish when recent, they never acquire a bony hardness, and are nearly always capable of slight lateral movement. The skin covering them is frequently stretched and glossy, and may exhibit white spots of urate of soda. The articular nodosities in chronic rheumatoid arthritis are actual osseous enlargements of, or outgrowths from, the articular surfaces, forming part of them, immovable and conserving more or less their form. The integument covering the nodosities is not glossy or dotted with chalk-like specks. The several types of deformity of the fingers previously described, and mainly produced in rheumatoid arthritis by muscular contractions and altered shape of the articular surfaces, are not seen in gout. Finally, if chalk-like concretions are visible in the ears, joints, or finger-ends, or if the blood contain uric acid, gout is present. While rheumatoid arthritis and chronic gout occasionally coexist in the same patient in England, in Canada, where the latter disease is comparatively rare and the former quite common, the writer does not remember to have observed such coexistence.
Besides the acute syphilitic disease of the joints already alluded to as occurring in children (inherited), a chronic arthritis is observed in the adult amongst the very late lesions of syphilis. It is usually monoarticular, affects the larger joints, especially the knee, and may originate either in the synovial membrane or in the bone and periosteum. In syphilitic synovitis the history of the case, the existence occasionally of soft gummy tumors in the periarticular tissues and of hydrarthrosis, the trivial degree of pain and tenderness, the insidious invasion and chronic course of the affection, and its prompt relief by antisyphilitic remedies, will indicate the nature of the case.
When it originates in the bone and periosteum, although the invasion may be prompt and the pain at first severe, the latter usually moderates greatly and becomes nocturnal, and the articular surfaces present localized rather than general enlargement (hyperostosis); nodes often coexist; effusion is moderate, unless the synovial membrane is also involved, and full doses of iodide of potassium will soon afford relief.
PROGNOSIS.—In the polyarticular form the course varies much more than is commonly believed, and the disease must not be regarded as necessarily progressive and incurable. When it occurs in young persons, and in children more especially, although it may suffer exacerbations and remissions for a few years, yet arrest of the disease and recovery of the functions of the joints, sometimes with very little deformity, now and then take place under suitable management. Quite recently a man of thirty-two consulted me about a vesical affection who from the age of eight had suffered every winter for twenty years from rheumatoid arthritis in his hands and feet, and finally in the knees. Yet when seen by me he had been free from pain in his joints for three years, and, although they were somewhat deformed, their movements were remarkably free and painless.
Several of my younger patients while bearing children rapidly and nursing them have had the disease in their hands or hands and wrists; exacerbations have recurred during subsequent lactations, and yet the disease has either become arrested or progressed very slowly and at long intervals. It is admitted, however, that these are all exceptional cases, and that the tendency both of polyarticular and of the monoarticular forms is to progress, and, either steadily or at intervals and by recurring attacks, to permanently deform the joints and impair their movements. Even under these circumstances, however, the patients may suffer little pain unless when forcible movements of the articulations are attempted.
On the other hand, while the disease cannot be regarded as curable under the employment of drugs, very much can frequently be done, especially in the polyarticular form, to relieve the suffering and to retard, if not arrest, the progress of the disease, and even to restore sometimes very considerably the functions of the joints. Neither of these forms of rheumatoid arthritis can be said to be dangerous to life, and they often exist ten or twenty years and more without seriously injuring the general health. Heberden's nodosities are incurable, but they are little more than deformities.
TREATMENT.—The treatment of rheumatoid arthritis is, as a rule, disappointing, and perhaps no affection requires more perseverence and self-reliance on the part of the physician or more hopeful resolution on that of the patient. Our first duty is to make an exhaustive search as to the probable cause of the disease, as its removal is an important step in the treatment of the affection, although such search is frequently futile, and many of the alleged causes may, after all, be mere antecedents or coincidences. However, inasmuch as the pathology of the disease is very obscure, any abnormal condition of organ or function that may be discovered should receive strict and prompt attention, lest it should, either through disturbed innervation or malassimilation or impaired nutrition or defective excretion, be the predisposing or exciting cause of the disease. In women the most careful inquiry should be made into the state of the ovario-uterine organs and functions, and the least departure from their norm should be at once treated. Deficient, excessive, or painful menstruation, leucorrhoea, ovarian irritations, or pain, even displacements of the uterus or ovary, should be corrected as soon as possible. Repeated pregnancy and prolonged lactation, recurring mental anxiety and physical fatigue, defects of diet, want of food, of sunlight, and of good air, residence in damp dwellings, occupations involving exposure to cold and wet, are conditions supplying important indications which too often are beyond the control of the physician, although they peremptorily require his attention. The general form is often met with in anæmic persons and in those of impaired health and vigor, and probably very rarely occurs under opposite circumstances; and there is a consensus of opinion that a lowering system of treatment is contraindicated in rheumatoid arthritis.
