Gonorrhoeal rheumatism, like gonorrhoea, is proportionally as well as actually much more frequent in men than in women (111 men, 7 women, Nolen); and the greater proclivity of the former has been attributed to the greater delicacy, sensibility, and complexity of the structures involved in them than in women by gonorrhoea. MORBID ANATOMY.--The lesions of gonorrhoeal rheumatism in the early stage resemble closely those of acute articular rheumatism; and it is probable, for opportunities of ascertaining by actual dissection are very rare, that the synovial membrane chiefly suffers. In more advanced stages the joints contain serous fluid in which fibrinous flakes and numerous leucocytes are found; the cartilages may be eroded and softened; and in some protracted cases even the bones may participate in the inflammation, and the changes found in polyarticular rheumatoid arthritis may be developed. Ultimately fibrous adhesions, resulting in ankylosis, may occur. Suppuration very rarely takes place, and it is probable that in such cases pyæmia is added to gonorrhoeal arthritis. {104} SYMPTOMS.--Gonorrhoeal rheumatism may attack any of the joints; it most commonly invades the larger at first, more especially the knee; the ankle is next in order of frequency, and then succeeds the shoulder, closely followed by the smaller joints of the hands and feet, which are very seldom affected primarily and antecedently to the larger joints. The temporo-maxillary, the sacro-iliac, the sterno-clavicular, the intervertebral, do not escape gonorrhoeal rheumatism more than they do rheumatoid or pyæmic arthritis.[270] The disease most frequently invades several joints simultaneously or successively, but, soon declining in many of them, it finally becomes localized in a few or rarely in a single articulation. It is monoarticular from the first in about 20 per cent. of cases, especially in the knees. [Footnote 270: Vide Fournier, _Nouv. Dict. de Méd. et de Chir.
