Along chiefly with the third form of gonorrhoeal rheumatism, or independently, the various muscles and nerves may be the seat of myalgia and neuralgia. The sciatic nerve is specially liable. In the same form are often met those ocular affections observed not infrequently in rheumatoid arthritis and very rarely in acute articular rheumatism--viz. conjunctivitis and iritis. Aqua capsulitis is more common than the others, according to Fournier. The ocular affections may precede, accompany, or alternate with the articular, and, not being due to direct introduction of the urethral contagium into the eye, are regarded as manifestations or localizations of gonorrhoeal rheumatism. The varieties of erythema sometimes present in primary acute articular rheumatism have been observed in gonorrhoeal rheumatism.
Much difference of opinion obtains as to whether inflammations of the heart, lungs, and serous membranes occur as manifestations or localizations of true gonorrhoeal rheumatism. Even those who, like Besnier, contend for the rheumatic nature of gonorrhoeal rheumatism admit that they are quite exceptional in that affection. Endocarditis is probably more frequent than pericarditis, and the aortic are more liable than the other valves to suffer. Gonorrhoeal endocarditis has been observed without the articular affection, although it is especially when several joints are involved and the pyrexia is well marked in gonorrhoeal rheumatism that the above visceral complications occur. While admitting that Morel,[273] Marty,[274] Pfuhl,[275] and others have reported what appear to have been authentic cases of gonorrhoeal endocarditis, I would remark that it must be almost impossible at times to distinguish a polyarticular acute gonorrhoeal rheumatism from ordinary acute articular rheumatism, and that in other instances the possibility of pyæmia developing in gonorrhoea, and producing both the articular and the visceral lesions, or the latter only, cannot be denied. And the same remarks are applicable to the cerebral and spinal disturbances that Vidart and others have recorded as occurring in gonorrhoeal rheumatism.
