220 Figs. 12 to 18 and 22 in Adams's Treatise on Rheumatic Gout are nice illustrations of these deformities.
The general condition in this chronic form varies in different individuals, and there is no characteristic disturbance of the functions, such as obtains in chronic gout. There is no elevation of temperature, unless to a slight degree during an active crisis of the disease; the tongue may be clean, the pulse tranquil, the appetite and digestion satisfactory, and the urine normal or perhaps pale and of low density. Fuller, however, says that "more generally the complexion is sallow and the skin sluggish, and evidence of mischief is furnished by yellowishness of the conjunctivæ, constipation of the bowels, a pale and unhealthy character of the dejections, excessive flatulence after meals, turbidity of the urine, and fulness of the pulse." My own experience hardly harmonizes with this, and I have seen many persons suffering for years from the general and partial form in the enjoyment of excellent general health. Should, however, the disease develop in a person the subject of menorrhagia or other uterine disorder, or of repeated child-bearing, or after prolonged mental anxiety, some disturbance of the general health fairly referable to such disturbing conditions may be certainly looked for. In the advanced stages the prolonged suffering and confinement often induce anæmia, dyspepsia, and failing health.
More numerous and exhaustive analyses of the perspiration, urine, and blood in the disease are needed. There is no uniform condition of the skin; general perspirations, chiefly at night, often obtain, but I know of no authoritative report as to the chemical reaction of the sweat in this disease; Garrod221 and Charcot222 vouch for an absence of uric acid in the blood, while Marrot223 found both this acid and the urea below the normal quantity in the urine, although the acid increased notably under baths of high temperature.

Certain affections other than the articular have been occasionally observed in persons suffering from rheumatoid arthritis, but many even of those authors who regard the disease as a form of rheumatism speak of these affections as coincidences, and not as essential manifestations of the disease. Charcot and Besnier, however, maintain the latter to be their true relation to the articular affection which they regard as chronic rheumatism. The two authors just named allege that all the visceral localizations that occur in acute articular rheumatism may obtain in the nodular form, but that such localizations are infinitely less frequent and serious than in the acute, subacute, or simple chronic forms of articular rheumatism—that endo- and pericarditis undoubtedly do occur in nodular rheumatism, and appear especially where there is an exacerbation of the disease and where there is some approach to the acute state.224 As Charcot has adduced these cardiac affections in proof of the rheumatic nature of rheumatoid arthritis, it is deserving of mention that he had personally met with but two instances of endocarditis and five of pericarditis, four of the latter having been discovered not during life, but in nine autopsies, and that he cites only eight other cases of endo- or pericarditis which had been either published or reported to him. He admits too that there had generally been in these cases, at some former period, an attack of acute rheumatism. Besnier, Homolle, Malherbe, Vidal, and Colombel, in their articles upon the disease under consideration, do not cite a single case in which they have seen cardiac disease in rheumatoid arthritis. On the other hand, McLeod, Garrod, Fuller, Flint, Senator, and Pye-Smith either deny or ignore the occurrence of cardiac disease as a manifestation or complication of this disease. My personal experience coincides with that of those authorities last cited, except in one instance, and that is open to the objection that the patient's father had had acute articular rheumatism, the mother was the subject of chronic deforming arthritis, and the patient had experienced during many winters an affection which began in the smaller joints and permanently damaged them; when first seen by me he had chronic disease of the aortic valves. He may have had true articular rheumatism as well as rheumatoid arthritis. His father had experienced the one, his mother the other. If those instances be excluded in which a former attack of acute rheumatism might be adduced in explanation of the supervention of cardiac disease, but few cases will remain to suggest that rheumatoid arthritis may develop endo- or pericarditis; and when it is borne in mind that in several ways the cardiac affections may have arisen as mere coincidences of the rheumatoid affection, it is well to wait for further evidence before accepting as proved the occurrence of cardiac affections as local manifestations of rheumatoid arthritis. Garrod's observation is still pertinent: "The form of the disease in which acute cardiac inflammation has occurred may be rather that of true articular rheumatism of a very subacute character."

Nor is the evidence at all satisfactory in favor of any special tendency to the following affections, much less of their being local manifestations of rheumatoid arthritis: viz. pleuritis (McLeod, Fuller), asthma (Charcot), chronic laryngitis (Garrod), grave cerebral or spinal disturbances (McLeod, Fuller, Vidal), paralysis agitans, locomotor ataxia, sciatica, trifacial neuralgia, and albuminous nephritis.225
225 To mention only some of the many sources of cardiac disease other than rheumatism may be adduced scarlet and other fevers, extension of inflammation from the pleura or lung and other sources of local irritation, powerful or oft-repeated muscular efforts, Bright's disease, senile degeneration, etc.
