RESUMEN
Objective: To determine the prevalence of the Stafne´s bone cavity in a Venezuelan population and to characterize it radiographically. Method: Descriptive and cross-sectional study. Of 500 panoramic radiographs, those that had radiolucent images in the mandible, circumscribed and not associated with any dental organ, as well as those that could correspond to the mandibular fossa, were selected. Results were collated and discrepancies resolved by consensus. The selected ones were characterized radiographically. The variables were compared using the student's t test for equality of means, applying the Levene test, values of p <0.05 were considered statistically significant. Results: Of the 500 radiographs evaluated, 22 presented images corresponding to deep mandibular fossa or Stafne bone cavities, which represented 4.4%. Of which 5 presented bilaterally (22.7%) and 17 (77, 3%) unilocularly. Among the radiographic characteristics studied, images located in the posterior area (81.81%), without sclerosis (54.54%), continuous to the basal mandibular area, round shape (59.09%) and partial radiolucency (72%) were presented with a higher prevalence). They were more common in male patients with 63.63%. Conclusions: Our results show a higher prevalence of Stafne's bone cavity in a Venezuelan population than that reported in other studies in other populations.
RESUMEN
Septic thrombophlebitis of the portal vein is an unusual and serious complication of abdominal infection. We present a patient with thrombophlebitis of the portal vein of unknown origin, suffering from fever, abdominal pain, jaundice, abnormal liver test function and bacteremia related to Bacteroides fragilis. Ultrasonography, with doppler of the portal vein, was performed which showed thrombosis of the portal vein together with signs of portal hypertension. The patient underwent six weeks of antibiotic treatment. The evolution was favourable, the infection was overcome and the portal vein was de-obstructed as a consequence of which the signs of portal hypertension disappeared. (Au)
