The purpose of his double-blind, randomized trial was to compare ear drops containing either trimethoprim and polymyxin B (TP) or trimethoprim, sulphacetamide and polymyxin B (TSP) from the points of view of effectiveness and safety. The 68 patients treated had otitis externa or recurrent otitis media with perforated ear-drum, or mastoid cavity with post-tympanoplasty infection. Satisfactory results were obtained in 60.6% of the cases with TP and in 88.6% with TSP. When evaluated by the Chi-square method with Yates' correction, the difference was statistically significant. There was no evidence of ototoxicity, fungal infection or local hypersensitivity with either preparation. The trial demonstrated that both ear drops were active and that TSP was much more effective than TP in the treatment of otorrhea.

One patient with an exposed scleral buckling element in the left eye was initially followed conservatively. Soon after exposure, he developed a retinal detachment in the fellow eye, resulting in loss of useful vision. Because of concern over possible redetachment and loss of vision in the remaining eye, the patient has been followed with the exposed element for more than 11 years. Treatment has consisted solely of prophylactic topical antibiotics.
Four antimicrobial agents (triple sulfa cream, doxycycline, ampicillin, and metronidazole) were studied by double-blind techniques to determine their effectiveness in the treatment of Hemophilus vaginalis vaginitis, documented by vaginal culture in 96 patients. Cure was confirmed by negative vaginal cultures 7 weeks after the start of therapy. Metronidazole proved to be effective in 20 of 22 couples (90.9%) treated. Sulfa cream, doxycycline, and ampicillin were effective in 47.8 to 63.6% of patients treated.
