Protracted fever of unknown origin as the presenting symptom of Behçet's disease. Report of a case.

We report a case of Behçet's disease that presented as protracted fever of unknown origin. The diagnosis was established when a thromboembolic event and ora3l aphthous ulcers occurred simultaneously. Antibiotics had no effect on the fever, which resolved when glucocorticoid and anticoagulant therapy was given. Among causes of protracted fever of unknown origin, Behçet's disease is exceedingly rare but should be considered together with the other vasculitides. Above all, the presence of a fever should prompt a search for a thromboembolic complication.

Multifocal pyomyositis in an immunocompetent patient.

Pyomyositis is defined as suppurative infection of the skeletal muscle and usually occurs in immunocompromized patients. We managed a 23-year-old man admitted for myalgia and evidence of infection, with onset after a strenuous physical activity. Numerous muscles were involved. Multiple abscesses were visualized by ultrasonography and computed tomography, with predominant involvement of the pelvic muscles. Examination of the aspirate from a forearm abscess recovered Staphylococcus aureus. No factors associated with immunodeficiency were found. Appropriate antimicrobial therapy ensured complete resolution of the infection. Pyomyositis is rare in immunocompetent individuals. Myalgia, fever, and rhabdomyolysis should suggest pyomyositis. Computed tomography and magnetic resonance imaging are the best investigations for confirming the diagnosis.

Osteoid osteoma multifocally located and recurrent in the carpus.

The authors report a case of osteoid osteoma located simultaneously at the right carpitate and at the proximal part of the right third metacarpian. A 31-year-old man presented in 1997 an osteoid osteoma involving the right capitate. One year after the surgical excision of the tumor, a second osteoid osteoma reappears to the same place requiring a 2nd intervention. A 3rd osteoid osteoma was discovered 16 months later at the proximal part of the right third metacarpian. After every excision, the pathological aspect was compatible with a nidus of osteoid osteoma. Osteoid osteoma of capitate are very rare. Multifocal forms are exceptional. If relapses of the tumor are sometimes explained by the incomplete excision of the nidus, the pathogenesis of the true recurrence remains unclear.

Lead-related gout. A case report.

Gout secondary to lead-induced nephropathy is a long-term complication of occupational lead exposure. We report a case of this now-rare condition. The patient was a 63-year-old man who had been a miner from 1950 to 1970. Thirty years after cessation of his exposure to lead, he experienced onset of inflammatory symmetric polyarthritis with joint deformities. Hyperuricemia, moderately severe renal failure, and tubular acidosis were found, indicating gouty polyarthritis. Blood lead levels were high, establishing that the cause was lead poisoning. EDTA chelation therapy was effective. Lead poisoning is frequently under-recognized because the clinical manifestations are often minimal and the diagnosis difficult to establish. We suggest that lead bound to bone may result in continued exposure to lead after cessation of industrial or environmental exposure. Chelating agents are valuable for the diagnosis and can ensure a full recovery.
