The danger of the case is usually proportionate to the youth of the patient, the degree of the pyrexia, the number of the joints involved, and the number and the character of the complications, the habits, and previous health of the patient. A fatal issue is most frequently observed in connection with hyperpyrexia alone, or in combination with delirium or coma. A rapid rise of temperature and a temperature over 105°, especially if cerebral disturbance coexist, indicate danger; and so does arrested perspiration while the temperature is high. In a much smaller number of cases death is due to some other complication, especially to purulent pericarditis or to that combined with pleuritis or pneumonia; in not a few cases the prior existence of chronic valvular disease, with fibroid induration of liver and kidneys, renders a fresh rheumatic endo- or pericarditis, occurring as part of acute articular rheumatism, fatal. There is good if not conclusive evidence that rather sudden death in acute articular rheumatism is occasionally due either to diffuse myocarditis or to fatty degeneration of the muscle of the heart. In Greenhow's 2 deaths out of 50 cases treated by sodium salicylate the pericardium was universally adherent and the heart's fibre fatty in one and pale and flabby in the other. Sudden death in this disease is very rarely due to embolism of the pulmonary artery or of the cerebral vessels, while ulcerative endocarditis is very exceptionally one of the sources of a fatal issue.127 But although acute articular rheumatism rarely kills directly, it frequently lays the foundation of subsequent ill-health, and ultimately proves fatal through organic disease of the heart and its many consequences. However, it is an interesting circumstance that while acute rheumatic inflammation is prone to damage the heart permanently, it very rarely, quite exceptionally, impairs the structure or functions of the articulations. It is almost solely the subacute form that now and then becomes chronic or renders a joint for a long time painful, swollen, and crippled in its movements. Whether acute rheumatism, however intense per se, ever ends in destructive suppuration and ulceration of a joint is doubted by some authorities, notwithstanding the cases published by Fuller and others. No doubt some of the cases were really pyæmic, or perhaps gonorrhoeal; and it must be borne in mind that acute articular rheumatism occasionally develops pyæmia, and then an arthritis might be considered rheumatic when truly pyæmic. The question of acute rheumatic arthritis exciting a chronic rheumatoid affection will arise hereafter.

TREATMENT.—Owing to our imperfect knowledge of the real nature of acute articular rheumatism, its treatment is still largely either empirical or intended to combat certain prominent symptoms or complications of the disease. Of the various methods of treatment which have been employed space will not permit a description; even of those advocated by authorities of the present hour only very few will be considered.
The method which is now unquestionably the favorite one in both Europe and America, and which in its power of promptly relieving the articular and muscular pains and reducing the fever of acute rheumatic polyarthritis may without exaggeration be compared to that exercised by quinia over the paroxysms of ague, is that in which salicylic acid or salicylate of sodium is given in repeated and full doses. It was in July, 1875,128 that Buss first asserted that salicylic acid was a specific for rheumatism, and in March, 1876,129 Maclagan, after having employed salicine from 1874, published his experience of it as a valuable remedy in the treatment of acute rheumatism, its beneficial action being "generally apparent within twenty-four, always within forty-eight, hours of its administration in sufficient dose." Perhaps a sufficient time has now elapsed to permit of a just opinion of the power of these new remedies, the salicyl compounds, over acute articular rheumatism. The facts presented at the discussion recently held at the Medical Society of London130 are sufficiently numerous and authoritative to justify, at least provisionally, some definite conclusions as to the remedial relations of the salicylates to acute articular rheumatism.
