ACUTE ARTICULAR GOUT.—A typical attack of acute gout is usually sudden. It seizes its victim without warning, and often rouses him from sleep with a vicious agonizing pain in the joint assailed. Examination will reveal a slight redness, heat, and puffiness of the part affected altogether disproportioned to the intensity of the pain; the tenderness is exquisite, and the torture is often aggravated by the occurrence of reflex spasms of neighboring muscles. There is usually moderate fever, and if the surface be exposed there may be a chill. Sleep is impossible and the restlessness uncontrollable. As the morning advances slight perspiration occurs, and sleep may become possible. With the abatement of pain there is coincident increase in the signs of inflammation: the joint swells, the skin becomes red and oedematous around the joint, and the superficial veins are distended. But, though the pain subsides with the occurrence of swelling, and usually in proportion to its degree, the tenderness and pain on any attempt to move the joint continue to be extreme. The day is passed in comparative ease, but the evening generally brings an exacerbation of pain and fever, and the night another paroxysm of agony—not as severe as the first, but severe enough to make the daylight a benison. The progress of the disease after the second day, provided it is confined to one joint, is usually marked by a steady and regular decline in the severity of the symptoms. If the attack is confined to a single joint, a week may elapse before the inflammatory signs subside, and it may be a fortnight before pressure can be borne or the mobility of the joint is restored. Occasionally the sufferings of an acute attack of gout may be protracted by successive seizures for several weeks. The fever during the attack is distinctly remittent, the evening exacerbation rarely exceeding 103° F.
The urinary symptoms before, during, and after an acute paroxysm of gout are interesting and important in their bearing upon the uric-acid theory of the disease. Garrod's statements upon this point are generally accepted, and have been confirmed by other observers. He says that previous to the attack the amount of uric acid in the urine is below the average—that during the paroxysm the proportion grows smaller, and only rises to the normal standard with the termination of the seizure. The reaction of the urine is strongly acid during the paroxysm. This is due probably to the increased excretion of acid phosphates. The quantity of the urine is generally diminished, the specific gravity increased, and the color deepened.
Attacks of acute gout are generally followed by improved health and capacity for physical and mental work and enjoyment. The blood seems to be purified, the processes of digestion and assimilation are once more normally performed, the equilibrium of the nervous centres is restored, and the evolution of all the vital energies proceeds with ease and vigor. This state of well-being may continue for a year or two years, or even a longer period, after the first attack, the immunity varying according to the intensity of the inheritance or the habits of life. The subsequent attacks are apt to occur at increasingly shorter intervals, and, as a rule, the acuteness of them tends to diminish. Gradually the dyscrasia becomes more profound, and the constitutional symptoms and structural changes which belong to the atonic and irregular forms of the disease are developed.
ATONIC GOUT.—Though subacute, irregular, or atonic gout is often the sequence of repeated attacks of the acute disease, it is not necessarily preceded by them, nor is acute gout invariably followed by a marked gouty dyscrasia. It is not uncommon for a well-characterized gouty habit to exist, manifesting itself by many and varied gouty phenomena, without the occurrence of any acute lesions, and repeated attacks of acute articular gout may occur without the development of the progressive impairment of health and the tissue-changes which distinguish the chronic malady. The recognition of this fact is important, inasmuch as the occurrence of acute gout is commonly regarded as an essential element in the diagnosis of the gouty dyscrasia. Acute articular attacks, as already noted, are very rare in women, in whom the subacute and irregular forms of the disease are by no means infrequent. So far as acute articular gout is of value in the diagnosis of the constitutional vice, it is perhaps as significant if established in the history of a near relative as in the individual in whom the disease is suspected.
The general symptoms of atonic gout—or, as it may more properly be called, the gouty dyscrasia—are similar to those which sometimes precede the development of the acute form. The difference lies in their persistence, in the subacute character of the local lesions, and in the absence of the relief to the constitutional symptoms which follows acute attacks.
The dyspeptic symptoms are perhaps the most pronounced and uniform in the history of the evolution of chronic gout. These symptoms have been already described, but the fact which seems especially to distinguish them is that they are chiefly provoked by the acid fermentation of the carbohydric elements of the food, the sugar and starches, and especially by the fermented preparations of alcohol; the ability to digest these articles of diet appears to be deficient in the gouty dyspeptic.
The changes in the urine in the gouty dyscrasia are especially important. In the formative stages of the gouty vice the amount of urine may not vary much from the normal quantity, but the proportion of solid constituents, especially of the urea, is increased, so that the specific gravity may rise to 1.030 or 1.035. The acid reaction is intensified by the excess of the acid urates and phosphates upon which the normal acidity depends. Sometimes crystalline deposits of uric acid, urates, and oxalates take place in the tubuli of the kidney and in the bladder, and lead to the nephritic and vesical irritations which are often the source of much inconvenience and pain. Where the urine is free from these crystalline constituents as it comes from the bladder it may deposit them within a few hours after its passage. At a later stage in the development of the gouty dyscrasia the quantity and quality of the urine undergo marked changes. The quantity is increased; the color is pale, partly in consequence of dilution and partly through a diminution in the amount of coloring-matter. The quantity may be so considerable as to constitute a polyuria. The reaction is neutral or only feebly acid; crystalline sediments of uric acid and calcium oxalate may occasionally appear, and the specific gravity may be so low as to indicate not only a relative but an absolute diminution in the daily excretion of urinary solids. Traces of albumen and of sugar are not infrequently observed.
The articular symptoms of chronic gout are subacute. They affect the joints, as a rule, which are most exposed to strain and injury, and hence are most common in the hands and feet, but they may involve the knee and the hips, the elbow and the shoulder, and even the intervertebral joints. The pain is less severe, because the tension is never so considerable; the tenderness is often a source of great discomfort; the swelling varies with the acuteness of the inflammatory process, the joints being more or less permanently enlarged by hypertrophic changes affecting the articular structures and by tophous deposits. The deformities are increased by ankylosis, by contractions, by absorption of the cartilages, by partial luxations, and by the atrophy of disused muscles. Crepitations are often observed in the affected joints. Exacerbations of the local symptoms are often provoked by movements, by imprudence in diet, by changes in temperature or in barometric and hygrometric conditions, and not infrequently by psychical disturbances.
The frequency with which tegumentary affections, mucous as well as cutaneous, are observed as correlative phenomena of arthritic lesions in gouty persons and in gouty families justifies the inference that the same lithæmic vice which determines articular inflammations is often responsible for derangements of nutrition in the skin and mucous membranes. The French school of dermatology, which has always maintained the humoral origin of many cutaneous diseases, has long recognized the arthritic nature of a large class of affections of the skin. Bazin7 has given the most precise description of the arthritides, as he terms them. He insists upon certain functional derangements of the skin as characteristic of the gouty diathesis, such as excessive perspiration, especially in certain regions, as the head, the axillæ, the hands and feet, and the sexual organs, and also affections of the sebaceous glands, causing the different forms of seborrhoea and the premature falling of the hair. He notes the liability in gouty persons to certain neurotic affections, such as pruritus, general or localized, about the arms and genital organs. Erythematous affections, especially urticaria, erythema nodosum, and the fugitive erythema which occurs about the face, causing sudden and evanescent swelling of the eyelids, cheeks, lips, and even the tongue and soft palate, are recognized by him and other observers as arthritic in their origin. Among the erythemata which are observed in gouty persons the peliosis rheumatica should be mentioned.
