How can you delete a work item that won't load?

We have a couple work items that looks like they may have become corrupted.  There were some socket errors reporting in the jazz.log, and database insert errors due to constraint (record already exists I think) in the jts.log.  Now a couple records won't load in either the eclipse nor web client, but others do.  Eclipse times out and web just says loading forever.  I'd like to delete the work items and recreate them, but not sure how that can be done when neither interface can pull them up.  Queries that would include these troublesome records are also never coming back until they error
