Successful Retrieval (successful + retrieval)
Selected AbstractsDifferential contributions of the anterior temporal and medial temporal lobe to the retrieval of memory for person identity informationHUMAN BRAIN MAPPING, Issue 12 2008Takashi Tsukiura Abstract Although previous studies have suggested the importance of the bilateral anterior temporal (ATL) and medial temporal lobes (MTL) in the retrieval of person identity information, there is little evidence concerning how these regions differentially contribute to the process. Here we investigated this question using functional magnetic resonance imaging (fMRI). Before scanning, subjects learned associations among faces (F), names (N), and job titles (as a form of person-related semantics, S). During retrieval with fMRI, subjects were presented with previously learned and new S stimuli, and judged whether the stimuli were old or new. Successful retrieval (H) trials were divided into three conditions: retrieval of S and associated F and N (HSFN); retrieval of S and associated F (HSF); and retrieval of S only (HS). The left ATL was significantly activated in HSFN, compared to HSF or HS, whereas the right ATL and MTL were significantly activated in HSFN and HSF relative to HS. In addition, activity in bilateral ATL was significantly correlated with reaction time for HSFN, whereas we found no significant correlation between activity in the right MTL and reaction time in any condition. The present findings suggest that the left ATL may mediate associations between names and person-related semantic information, whereas the right ATL mediates the association between faces and person-related semantic information in memory for person identity information. In addition, activation of the right MTL region implies that this area may contribute to a more general relational processing of associative components, including memory for person identity information.

We report a case of left atrial thrombus that formed around the circular mapping catheter before the delivery of RF. Successful retrieval of the clot was obtained by withdrawing the catheters while protecting the anterior cerebral circulation by positioning temporary carotid artery filters.

Casserly Abstract In adults, paradoxical embolization of catheters or guidewire fragments related to central venous catheterization is a rare phenomenon. Reports of successful percutaneous retrieval of foreign bodies from the left atrium is also rare. We describe the successful percutaneous retrieval of a fractured guidewire that had undergone paradoxical embolization to the left atrium in an adult patient.

Prabhakar Abstract Aim, To describe the successful retrieval of a foreign object located in the apical portion of an immature root canal by simple orthograde techniques, avoiding the need for surgery or intentional reimplantation. Summary, A radio-opaque foreign object lodged in the apical portion of an immature root canal was discovered on radiographic examination of a patient with a complicated crown fracture. Attempts to retrieve it resulted in displacement into the periapical area. Eventually, the object was retrieved by a simple technique, followed by successful apexification, root canal filling and jacket crown placement. Key learning points ,,Foreign bodies in root canals should be carefully evaluated to determine their nature, position, size and the degree of difficulty that may be encountered during retrieval. ,,Patience, care and appropriate techniques may be helpful in retrieving foreign bodies and avoiding periapical surgery. ,,Complicated crown fractures should be managed promptly, and prolonged open drainage avoided in children if the risks of foreign body impaction are to be minimized.
