RESUMO
We report the case of a patient with a gunshot wound in the chest with a multiple small-caliber intrathoracic projectiles. The different noninvasive techniques employed to evaluate the anatomical location of these projectiles are discussed, together with their cardiac structural repercussions. The data provided by a simple chest X-ray, Computed Tomography (CT) and transthoracic echocardiography are commented on. A simple chest X-ray was unable to discern the location of the projectiles, in contrast to CT, which was able to identify both the number of projectiles and their location. The information provided was enhanced by transthoracic echocardiography, particularly in relation to those projectiles situated in anterior cardiac regions.

In order to document the incidence of hepatitis delta virus (HDV) replication markers and their relationship to HBV replication, 91 HBsAg chronic carriers were studied. Of these, 51 were anti-HD-positive (19 HBeAg-positive and 32 anti-HBe-positive). Liver HDAg was found in 75% of anti-HD-positive patients. Of the 19 patients who had anti-HD and HBeAg, 13 were HBV-DNA-positive. None of the anti-HBe patients were HBV-DNA-positive. No differences with respect to HBV-DNA concentration were observed between anti-HD-positive and -negative patients. Liver HDAg was detected with similar frequency in patients who were HBeAg- and HBV-DNA-positive (63.6%) and in those who were anti-HBe-positive (78.5%), with no statistically significant difference. HBcAg and HDAg were simultaneously detected in 36% of the anti-HD cases. Patients with anti-HD and HBV-DNA had the highest levels of transaminases (SGPT). Our results suggest that in certain patients HDV and HBV replication coexists without mutual inhibition.
