In the presence of extraosseous activity seen in the late phase of the bone scintigraphy (BS) localized in the distal femur of patients prior to radiation synovectomy, we decided to review the frequency of this finding in 20 patients (24 joints) and its relationship with scintigraphic and clinical parameters. Mild soft tissue accumulation was seen in the late phase of the BS in 14 out of 24 joints, without association between this finding and knee uptake in vascular blood pool and late phases of the BS. However, a significant association with synovial effusion was found, and patients with higher degree of effusion presented extraosseous activity more frequently. In conclusion, we think that soft tissue accumulation in the late phase of the BS is a sign of synovial effusion.

Ante la observación de actividad extraósea alrededor del tercio distal del fémur durante la fase tardía en algunos pacientes a los que se realizó una gammagrafía ósea (GO) y posterior radiosinoviortesis, revisamos en 20 pacientes (24 articulaciones) la frecuencia con la que apareció este hallazgo y su relación con parámetros gammagráficos o clínicos. Hemos encontrado una leve captación extraósea en la imagen tardía de la GO en 14 de 24 articulaciones, sin que haya existido asociación entre ésta y la intensidad de captación de la rodilla en las fases de pool vascular y tardía de la GO, pero sí con la presencia de derrame articular siendo más frecuente en aquellos con derrame más severo. En conclusión, pensamos que la presencia de captación (AU)

BACKGROUND: To study the seroprevalence of hepatitis C virus in a cohort of six patients with a diagnosis of polyarteritis nodosa (PAN). METHODS: There have been included six patients with a diagnosis of PAN, carrying out a serodiagnosis of hepatitis B virus (VHB) and C (VHC) this last one by means of the following methods: ELISA, RIBA-II and PCR. RESULTS: These cases (50%) showed exclusive positivity to VHC by means of the three ways of diagnosis, two cases showed positivity to VHB (33.3%), one case (16.6%) showed positivity to both virus (VHB and (VHC) and one case didn't show positivity virus. CONCLUSIONS: It is probable a ethipatogenic relation between hepatitis C virus and polyarteritis nodosa, our sample doesn't show any difference from that written in the literature. The positive rheumatoid factors can give false positive for VHC by means of the technique ELISA because of this it is necessary to confirm the positive by means of the techniques RIBA-II and PCR.
