Prevalence and clinical characteristics of otitis externa among patients attending Otorhinolaryngology Department at Muhimbili National Hospital, Tanzania

Abstract

<p class="abstract"><strong>Background:</strong> Otitis externa is among the otological diseases with significant impact on the quality of life of sufferers. Little is known in Sub Saharan countries despite being the focus of such disease. The study aimed to determine the prevalence and clinical characteristics of otitis externa at Muhimbili National Hospital, Tanzania’s largest tertiary hospital.</p><p class="abstract"><strong>Methods:</strong> This was a hospital based descriptive cross sectional study where 1200 participants were recruited from June 2016 to January 2017. Data was analyzed using SPSS program version 20. </p><p class="abstract"><strong>Results:</strong> A total of 1200 patients were recruited in this study and majority 601(50.1%) were females. Majority 672(56%) were in age group 0–10 years. Among 1200 patients, 138 (11.5%) were diagnosed to have otitis externa and male predominance (55.1%) was found. Majority 120 (87%) had diffuse otitis externa and with 0-10 years (25.83%) being the commonly affected age group by variant. The commonest risk factor was self-ear cleansing 87(53.7%) and only 2.9% were found to have complications of otitis externa.</p><p class="abstract"><strong>Conclusions:</strong> Otitis externa was found to be prevalent and with male predominance. Self-ear cleansing was the commonest risk factor. Complications of otitis externa were found to be rare. Public awareness on otitis externa should be advocated in our country.</p>

Prevalence of antimicrobial resistance and its clinical implications in Ethiopia: a systematic review

“…In other African countries, Streptococci species showed higher rate of resistance (40%) to ceftriaxone [ 22 ]. However, a report in Tanzania indicated a resistance rate to ceftriaxone (4.4%), penicillin (38.3%) and amoxicillin/clavulanic acid (40.4%) [ 23 ]. The possible explanation for these discrepancies might be due to differences in the study population, methods used, geographical variations in disease burden, practice of antimicrobials use and presence, and implementation of national antimicrobials use policy.…”

Otitis externa in a tertiary hospital in the South-South region of Nigeria: a three year review

“…6,15 The prevalence was also noted to decrease after age 60 years similar to the finding in a study in Enugu, but differing from that of Abraham et al where age >65 years were found to be more affected. 22,25 In contrast some other researcher found the peak age to be in 7-12 years age group. 26 In the present study, chronic otitis externa was found to be the commonest form encountered.…”

“…19 In the present study, there was no statistical significant difference in distribution noted for sex, age and types of otitis externa similar to what was depicted in the study from Tanzania however; there was a statistically significant difference in the distribution of treatment duration and types of otitis. 25 Otitis externa therefore was found to be a common otologic condition seen in the ORL clinic and chronic type was the commonest form encountered in our environment.…”
