[Pseudoseptic arthritis with foreign body synovitis in a patient with gout]. / Artritis seudoséptica presenta sinovitis por cuerpo extraño en un paciente con gota.

Monoarthritis is a diagnostic challenge for the clinician, as the list of associated conditions is quite long. It is accepted that in patients with a diagnosis of inflammatory joint disease monoarthritis represents exacerbation of the underlying disease. However, ignoring the systematized approach to monoarthritides may lead to omissions and mistaken diagnostic implications. This report describes the approach to a case of pseudoseptic arthritis that mimicked an acute episode of recurrent arthritis due to monosodium urate in a patient with retention of an intraarticular foreign body.

Leptospiral antibodies in captive lion tamarins (Leontopithecus sp) in Brazil.

Serum samples from 73 lion tamarins of three species living at the Centro de Primatologia do Rio de Janeiro were tested for antibodies against serovars of Leptospira interrogans by microscopic agglutination test. Antibodies were detected in serum samples of 15% of tested samples. Seroreactivity prevalence was lower than that described in other non-human primates and could be explained by the arboreal behaviour of these animals. Icterohaemorrhagiae was the most common serogroup.
