ABSTRACT
PURPOSE: To evaluate the intraoperative contamination of the anterior chamber in eyes undergoing phacoemulsification in a university teaching hospital. DESIGN: Prospective, non-randomized clinical trial. METHODS: This study included 113 eyes of 113 consecutive patients undergoing cataract surgery performed by experienced surgeons and residents. Phacoemulsification was conducted through a scleral tunnel incision or through a corneal incision. The intraocular lens was implanted with an injector. Aqueous fluid was obtained at the end of surgery before viscoelastic removal, with a cannula through the corneal paracentesis. Povidone-iodine 10% solution was used to prepare the eyebrow and eyelids and povidone-iodine 5% to disinfect the ocular surface. All patients were given a single oral dose of 400mg ofloxacin 2h before surgery. No preoperative antibiotics were administered locally. RESULTS: Anterior chamber fluid aspirates were positive for bacteria in two eyes (1.8%). No eye developed endophthalmitis during the follow-up period. DISCUSSION AND CONCLUSION: Low anterior chamber bacterial contamination rates may be achieved under routine phacoemulsification in a teaching hospital practicing careful antisepsis measures.

We report on a 11-year-old boy who had 2 acute hemiparesis episodes over a period of 1 month. He suffered from headache and fatigue since 1 year. He could not remember neither a tick bite nor a local erythematous skin lesion. The diagnosis of neuroborreliosis was based on intrathecal production of specifics antibodies. Furthermore, the CSF/blood glucose ratio was decreased (0.14), which was rarely described. Cranial MRI showed left capsulothalamic inflammation and a vasculitis. The patient was successfully treated by ceftriaxone. Neuroborreliosis should be considered in all children with stroke-like episode, even in the absence of a history of a tick bite.
