Abstract:
The authors describe a 54 year-old male patient, admitted after presenting in the emergency room with acute oligoarthritis affecting the shoulders and right tibiotarsal and sternoclavicular joints, with a week's duration. He was non-febrile and related a purulent discharge from the stump of a traumatic amputation of the left thumb, starting a few days prior to the presenting complaints. There was a previous history of gouty arthritis and moderate alcoholism. Lab work revealed an elevation of the acute phase markers, with marked neutrophilia. Upon admittance, the patient underwent arthrocentesis, revealing a purulent discharge with sodium monourate crystals, which cultured positively for meticillin-sensitive Staphylococcus aureus. Besides antibiotherapy, on Day 5 the patient presented with a cervical abscess with extension to mediastinum; the abscess was drained by a cardiothoracic surgeon, and the right sternoclavicular and first costochondral articulations were found to be destroyed. The authors note that, although it is a rare occurrence septic arthritis can coexist with gout, while discussing the possible mecanisms of this association, as well as particular details of the clinical case presented.
