1/342. Gouty os trigonum tarsi: case report. Os trigonum tarsi is found in 7% of the world adult population. However, it rarely causes symptoms. The majority of patients with os trigonum tarsi are found incidentally. This condition is often found in ballet dancers, javelin throwers and soccer players. It rarely produces symptoms in normally active adults. The etiology of os trigonum syndrome is impingement of an unfused ossicle or a fractured posterior lateral tubercle of talus over the posterior rim of tibial plafond. We present a case of os trigonum syndrome in a young man. His posterior heel pain was due to tophaceous gout around the os trigonum tarsi, instead of the common pathogenesis of repeated hyperflexion of the ankle joint. Pictures of the specimen showed marked giant cell reaction which resulted in pseudotumor formation. We reviewed the clinical characteristics of os trigonum tarsi and gout and present the treatment of our patient. ( info) |
2/342. Multicentric reticulohistiocytosis: a mimic of gout and rheumatoid arthritis. Multicentric reticulohistiocytosis is a rare cutaneous-articular disease that may mimic more common disorders such as rheumatoid arthritis or tophaceous gout. In one fourth of patients, it is a paraneoplastic process. This brief overview is aimed at physicians who care for patients with polyarthritis, to alert them to distinctive features that differentiate multicentric reticulohistiocytosis from the common arthritides.

3/342. Sparing effect of hemiplegia on tophaceous gout. The sparing effect of hemiplegia on the development of tophaceous gout is described. The useless upper limb had no tophaceous deposits and the partially paralysed lower limb had only limited urate deposits. Disuse was presumably the major contributor to the limited deposition of urates on the paralysed side. ( info) |
4/342. gout and secondary amyloid. A case of gout and secondary amyloid is described. This rare association is described and the literature is reviewed. ( info) |
| The existence of gout in a total knee arthroplasty (TKA) may be more common than is currently recognized. We report 2 cases of acute recurrence of gout in knees after TKA, 1 with coexistent infection. ( info) |
6/342. Patellar stress fracture: a complication of knee joint arthroplasty without patellar resurfacing. A case of patellar stress fracture after total knee arthroplasty in a man with gout and previous osteonecrosis of the tali is reported. The combination of fat pad excision and lateral release causing disruption to the patellar blood supply during primary total knee arthroplasty resulted in the development of a patellar fracture. Avascular necrosis, caused by gout, may form part of the pathogenesis. ( info) |
7/342. Occurrence of gouty tophi following acitretin therapy. acitretin (Ro 10-1670 or Neotigason), a free acid and the main metabolite of etretinate (Ro 10-9359 or Tigason), is the most recent of the retinoids used orally in the treatment of psoriasis and numerous other dermatoses exhibiting disorders of keratinization. In the majority of cases, its side-effects are similar to those of hypervitaminosis a. ( info) |
8/342. Case report. Initial manifestation of gout after carpal tunnel release. A carpal tunnel release was performed on a patient with recurrent carpal tunnel syndrome and asymptomatic hyperuricaemia with no prior history of gouty arthritis. Intraoperatively, the patient was found to have tenosynovitis without crystals or tophaceous deposits in the carpal tunnel. Postoperatively, the patient developed an acutely inflamed hand, which responded dramatically to anti-gout medications. We report this patient as an initial attack of gout after a carpal tunnel release. ( info) |
9/342. gout: beyond the stereotype. Not all gout presents with involvement of the big toe, and not all gout patients are middle-aged men. Chronic gout may mimic rheumatoid arthritis; hyperuricemia may develop in postmenopausal women and in organ transplant recipients who are being treated with immunosuppressive agents. Both classic and nonclassic cases may benefit from new therapeutic agents. ( info) |
10/342. Kienbock's disease and gout. A relationship between gout and Kienbock's disease has been proposed on the basis of a previously published case report. A review of patients at our institution identified a single case with the combination of both Kienbock's disease and gout. We believe that the association is coincidental. ( info) |
