Naturally, the implication of so many varied structures casts its impress on the clinical picture, inasmuch as the physical characters vary with the different textures involved, their capacity for inflammatory distension, etc. On the dorsum of the hand and foot redness and œdema will be prominent, and Scudamore noted that the flush might be widely diffused, simulating erysipelas, with here and there small ecchymoses.

When structures more deeply placed, i.e., tendon sheaths at ankle, knee, and wrist, are singled out for attack, swelling is less marked and redness of the skin more patchy in distribution. The bursæ at the elbow or back of the knee may swell with extraordinary rapidity. The parts become exquisitely tender and painful, while the overlying skin takes on an angry blush. They may subside, but more often continue permanently enlarged, defiant of reduction.

Involvement of the olecranon bursa is very typical of gout. Pratt, of Boston (1916), tells of a case in which the subject had during twenty-seven years suffered from recurring attacks of acute gouty polyarthritis. The eight or ten physicians who had treated him had all regarded the disease as rheumatic fever. Pratt himself observes: “I did not feel sure of the diagnosis until I saw the swelling on his elbow, which presented the typical picture of a chronic gouty olecranon bursitis.”[34] Occasionally the bursæ when filled with uratic deposit undergo suppuration following injuries. The bursa in connection with the great toe frequently becomes acutely inflamed, and Scudamore in a gouty hand saw an old ganglion take on the same inflammatory reaction.

The tendon sheaths when involved lead to great disablement, as even the most tentative attempts at movement give rise to sudden and agonising cramp. The tendo Achillis is a favourite site, or the tendons of the wrist, or the ligament of the patella. The same is true of the aponeuroses, the predilection being for the lumbar or gluteal fascia, in which instance it may extend to the sheath of the sciatic nerve. These extensions of gout to tendon and nerve sheaths frequently outlast the articular lesions, and may become the dominant element in the clinical picture.

Naturally, when not only joints, but bursæ and other structures, are involved and implicate both upper and lower limbs, the victim presents a pitiful spectacle, one of almost complete helplessness. Œdema and general venous turgescence may be very pronounced in one or more members, giving a subjective sensation of almost overwhelming weight in the limb.

Reverting to the constitutional symptoms, the outstanding feature is that, notwithstanding the widespread involvement of joints with manifest local inflammatory reaction, the pyrexia is of moderate grade, and so frequently, indeed, is it afebrile that this peculiarity is of diagnostic significance.

Changes in the Blood.—The findings are extremely interesting in view of the high grades of leucocytosis to be met with both in pyrexial and apyrexial examples.

In a case of acute gouty polyarthritis under my care the blood picture was a very striking one. The patient had suffered from gout for some eleven years, with recurrent acute exacerbations. There was widespread involvement of the joints both in upper and lower limbs. On the dorsum of the mid-phalangeal joints small semi-solid swellings were present, the exact nature of which was somewhat puzzling. But inasmuch as the pinna in both ears was studded with tophi, this seemed to provide a clue. The auricular tophi were verified microscopically. The extra-articular phalangeal swellings were then aspirated with a hypodermic syringe. A turbid straw-coloured fluid issued, which microscopically was found to contain biurate crystals. His temperature rose nightly from 101° up to 102° F., with morning remissions. The left knee and wrist were the seat of effusion, and some of the small finger joints were inflamed.
