Lacrimal sac compression by an anterior ethmoidal mucocele presenting as a late complication of dacryocystorhinostomy.

This was an unusual case of lacrimal sac compression by an anterior ethmoidal mucocele presenting as a late complication of a dacryocystorhinostomy (DCR) that was jointly managed by ophthalmic and ENT surgeons via an endoscopic approach. A 22-year-old lady presented with a 12-month history of a painless lump in her left medial canthus area and a 6-month history of left intermittent epiphora. She had a DCR when she was 15 years old with initial symptom control until recent recurrence.

The role of feedback in improving the effectiveness of workplace based assessments: a systematic review.

Background: With recent emphasis placed on workplace based assessment (WBA) as a method of formative performance assessment, there is limited evidence in the current literature regarding the role of feedback in improving the effectiveness of WBA. The aim of this systematic review was to elucidate the impact of feedback on the effectiveness of WBA in postgraduate medical training.

Methods: Searches were conducted using the following bibliographic databases to identify original published studies related to WBA and the role of feedback: Medline (1950-December 2010), Embase (1980-December 2010) and Journals@Ovid (English language only, 1996-December 2010).
