IntroductionAcute otitis externa (AOE) is a common but preventable ear condition. Tenderness with movement of the tragus or pinna is a classic feature of otitis Externa. Polymyxin B, neomycin, hydrocortisone preparations are the choice for first-line therapy when the tympanic membrane is intact. This study atiempted to compare the efficacy of polymyxin B, neomycin and polymyxin B, neomycin, hydrocortisone in the treatment of otitis Externa.ObjectiveTo compare the efficacy of polymyxin B, neomycin and polymyxin B, neomycin, hydrocortisone in the treatment of otitis Externa.MethodologyTo evaluate the efficacy of polymyxin B, neomycin and polymyxin B, neomycin, hydrocortisone in the treatment of otitis Externa, a hospital based, randomized, prospective study was conducted in Nepal Medical College and Teaching Hospital (NMCTH), Atiarkhel, Kathmandu from August 2012 to May 2014. 70 outpatients suffering from otitis Externa who met the inclusion and exclusion criteria were included. Patients were randomized into group A and group B with lotiery system. Odd number patients were included in group A and even number patients in group B. Group A patients received pack soaked with ribbon gauge in polymyxin B, neomycin ointment and Group B patients received pack soaked with ribbon gauge in polymyxin B, neomycin, hydrocortisone ointment. The patients were called for follow up after 48 hours and 96 hours to assess the improvement on the basis of tragal and circumduction tenderness either present or absent (present 1 or absent 2). A decrease in the clinical signs and symptoms (i.e. tragal and circumduc_on tenderness) was noted. Absence of pain was considered as clinically cured.ResultsIn comparison to polymyxin B, neomycin group, hydrocortisone group exhibited statistically significant effectiveness after 48 hours of treatment (p<0.05), but in cure rates after 96 hours, no statistical significant difference was observed between two groups (p>0.05).ConclusionPolymyxin B, neomycin, hydrocortisone group showed higher and faster cure rates than polymyxin B, neomycin group in the treatment of otitis Externa at 48 hours follow up. Birat Journal of Health SciencesVol.2/No.1/Issue 2/ Jan - April 2017, Page: 162-167

Microbial Agents

In this study, a total of 277 unmedicated dogs with otitis externa were used. Overall, 413 agents were isolated from 277 ear swab samples; 52.7% of the cases were mono-infections (146 cases), and 37.1% of the cases were poly-infections (103 cases). In 10.1% (28) of the cases, neither bacteria nor yeasts were isolated. Coagulase-positive Staphylococcus spp. were the most frequently isolated bacteria and were found in 90 (21.8%) of the samples. Fifty-eight samples, (14%) were positive for Staphylococcus aureus, 51 (12.3%) for Pseudomonas aeruginosa, 27 (6.5%) for Proteus mirabilis, 27 (6.5%) for Malassezia pachydermatis, 21 (5%) for Corynebacterium spp., 21 (5%) for β-haemolytic Streptococcus spp., 15 (3.6%) for Staphylococcus pseudointermedius, 12 (2.9%) for Proteus spp., 12 (2.9%) for Escherichia coli, 9 (2.1%) for Acinetobacter calcoaceticus, 7 (1.6%) for Trichophyton mentagrophytes, 5 (1.2%) for Staphylococcus auricularis, and 46 (11.1%) for different bacteria and yeasts. A total of 14 different bacteria and yeasts were isolated and identified. Kirby-Bauer antibiotic susceptibility testing was carried out for 10 different antibiotics. The bacterial isolates were found to be resistant to amoxicillin-clavulanic acid (45%), gentamycin (28%), ampicillin/cloxacillin (69%), tobramycin (28%), amikacin (23%), enrofloxacin (47%), chloramphenicol (58%), doxycycline (65%), lincomycin/spectinomycin (58%) and polymyxin B (62%). In conclusion, it is important to test the antimicrobial sensitivity of aetiological agents of otitis externa before treatment so as to prevent the development of antibiotic resistance in bacteria and yeasts.

Key Points Otitis externa most commonly caused by Pseudomonas aeruginosa or Staphylococcus aureus bacteria.Examination noted to have swelling of ear canal, possible discharge, pain on movement of pinna or tragus.TreatmentFor intact tympanic membrane, can use neomycin, polymyxin B, or trimethoprim sulfate.For non-intact tympanic membrane or tympanostomy tube–associated otorrhea, use fluoroquinolones (eg, ciprofloxacin, ofloxacin).Malignant otitis externa (ie, rapid soft tissue and bone involvement) is characterized by severe pain, copious discharge, and possible facial paralysis and requires admission with imaging and intravenous antibiotics.
