[Herpes simplex keratitis following laser in situ keratomileusis]

CASE REPORT

A 40-year-old woman underwent bilateral Laser In Situ Keratomileusis (LASIK) for the correction of myopia and astigmatism. The day after, four dendritic ulcers appeared in her left eye. She was treated with topical antiviral agents until complete recovery. She had a history of recurrent labial herpetic infection.

DISCUSSION

Reactivation of herpes simplex virus type 1 can occur, even without any previous history of corneal infection. Although this does not contraindicate surgery, all patients with a history of herpetic infection should be made aware of the complications related to this technique.

Susceptibility of Helicobacter pylori to mupirocin, oxazolidinones, quinupristin/dalfopristin and new quinolones

The in vitro activities of mupirocin, quinupristin/dalfopristin, linezolid, eperezolid, sitafloxacin, clinafloxacin, moxifloxacin, amoxycillin, metronidazole and clarithromycin were tested at pH 7.4 against 57 strains of Helicobacter pylori. The most active agents (mupirocin, sitafloxacin and clinafloxacin) were also tested for activity at pH 5.4 against the same strains. Mupirocin was very active at pH 7.4 and 5.4 (MIC90 0.25 and 0.12 mg/L, respectively). Quinupristin/dalfopristin, linezolid and eperezolid had low activity (MIC90 4, 8 and 4 mg/L, respectively). Sitafloxacin (MIC90 </= 0.008 mg/L) was the most active fluoroquinolone, while clinafloxacin (MIC90 0.12 mg/L) and moxifloxacin (MIC90 2 mg/L) were least active.
