Targeting the reconsolidation of traumatic memories with a brief 2-session imaginal exposure intervention in post-traumatic stress disorder.

Background: Evidence suggests that extinction during memory reconsolidation diminishes the return of defensive responses. In order to translate these effects to the clinical setting, we tested whether retrieving a traumatic memory and delivering a brief two-sessions imaginal exposure intervention during its reconsolidation would produce stronger decreases in reactivity to these memories than standard imaginal exposure method.

Methods: Participants with Post-Traumatic Stress Disorder (PTSD) had either their traumatic (n = 21) or a neutral (n = 21) memory retrieved 1 h before an imaginal exposure session for two consecutive days.

[Transitory hepatic peliosis in a child].

A case of hepatic peliosis in a 4 year old child is reported. The exceptional character of such a presentation in a child, along with its reversibility, are emphasized. The hepatogram performed during splenoportography showed numerous little granular pictures, which probably corresponded to the opacification of "peliotic" cavities.
