To compare the rates of cure of septic abortion and pelvic inflammatory disease using a daily dose of clindamycin with gentamicin versus divided doses, we conducted a retrospective cohort study, where the electronic records of 661 patients who used clindamycin 1 × , 3 × or 4 ×/day (groups 1, 3 and 4, respectively) between September 2002 and August 2010 were analysed. Major outcomes included rates of cure and failure according to the clinical records. Secondary endpoints were percentage of adverse effects related to medication regimen and the prevalence of positive VDRL and HIV. Similar conditions were observed in all groups - septic abortion: 167/116/123; pelvic inflammatory disease: 73/95/87 (groups 1, 3 and 4, respectively). No significant difference was found among groups for age or for rate of cure. Rates of cure (cure/total [rate (95%CI)]) in groups 1, 3 and 4 were 236/240 [0.983 (0.957-0.993)], 205/211 [0.971 (0.939-0.986)], 203/210 [0.966 (0.932-0.983)], respectively. Days of use of clindamycin was significantly reduced in group 1, compared to groups 3 and 4 (2.6 ± 1.3 vs. 3.5 ± 2.5 vs. 3.3 ± 1.9-mean ± SD; p < 0.0001 - ANOVA), but this may be due to differences in how length of therapy was measured and not the effect on clinical cure.

P229Results: Varying degrees of EH were observed in 14 of the 16 ears. Episodes of acute sensorineural hearing loss or vertigo occurred in 4 ears with severe EH in the cochlea and 3 ears with severe EH in the vestibules. Overall, 12 of 14 ears with EH did not undergo stapes surgery. Ears without EH showed no postoperative complications, but one ear with mild EH in the vestibule showed severe vertigo following the surgery. Conclusions:The presence of EH in cases with otosclerosis was clearly visualized, and the degree of EH was correlated with the clinical findings in most patients. Such preoperative MRI evaluation could provide useful information to prevent complications following stapes surgery.
