The most frequently isolated organism in chronic suppurative otitis media from different parts of the world is Pseudomonas aeruginosa. The pattern from this bacteriological study from our region is different. This study was carried out on 97 patients presenting to the outpatient clinic of the National Ear Care Center, Kaduna. Nigeria from May 2008 to April 2009. The patients were aged between 1 year and 75 years comprising 50) males and 47 females giving a male to female ratio of 1:1. Most of the patients (n=40, 41.2%) were in the age group 1-10) years. Seventy-five (77.3%) patients had a positive culture while in 22 (22.7%) patients there was no growth. Gram-negative bacteria comprised 80% of the isolates. The predominant organisms cultured were Klebsiella sp (n=31, 41.3%), Escherichia coli (n=22, 29.3%) and Pseudomonas aeruginosa (n=6, 8%). The gram-positive isolates were Streptococcus sp (n=8, 10.8%) and Staphylococcus aureus (n=7, 9.3%). In-vitro drug sensitivity pattern of all isolates shows that they were more sensitive to Ofloxacin, ciprofloxacin and Perfloxacin. Klebsiella sp. Escherichia coli and Streptococcus sp. are the leading pathogenic organisms in chronic suppurative otitis media in our region and their ensitivity rates are highest to the quinolone antibiotics, which are relatively cheap, readily available as ototopic agents and lack ototoxic effects.

No therapy is currently available to reverse the serious damage that can be caused by ototoxic drugs, such as permanent hearing loss and balance disorders. Otolaryngologists in various regions of the world have developed strategies aimed at curtailing drug-induced ototoxicity, but similar efforts in most developing nations have yet to be well established. We conducted a study to document our experience in Nigeria. Our study population was made up of 156 patients-66 males and 90 females, aged 5 to 85 years (mean: 32.1 ± 30.7)-who were diagnosed with drug-induced ototoxicity over a 3-year period. Tinnitus was the first and the predominant symptom in 140 patients (89.7%). The most common cause of drug-induced ototoxicity among the 156 patients was injection of an unknown agent (n = 55 [35.3%]); among the known agents, the most common were chloramphenicol (n = 25 [16.0%]), chloroquine (n = 22 [14.1%]), and gentamicin (n = 20 [12.8%]). One pregnant woman experienced a miscarriage at 4 months after receiving intramuscular chloroquine, and another woman fell into a coma after receiving intramuscular streptomycin. Two agents that have not been linked to ototoxicity-oxytocin and thiopentone sodium-were found to be ototoxic in our study (1 case each). Of the 312 ears, 31 (9.9%) showed normal audiometric patterns; on the other end of the spectrum, 155 ears (49.7%) had profound sensorineural hearing loss (SNHL). Mixed hearing loss was seen in 90 ears (28.8%). Hearing loss was bilaterally symmetrical in 127 patients (81.4%), bilaterally asymmetrical in 15 patients (9.6%), and unilateral in 14 patients (9.0%). Treatment was primarily medical; hearing aids were fitted for 7 patients (4.5%). Only 41 patients (26.3%) kept as many as 3 scheduled follow-up appointments. Ototoxicity remains prevalent in the developing countries of Africa. Numerous drugs and other agents are responsible, and management outcomes are difficult to ascertain. Thus, our emphasis must be placed on prevention if we are to minimize the potentially devastating effects of ototoxicity. © 2015 Vendome Group, LLC.

Hearing loss among people in developing countries has been recognized as a major source of disability. Many of its causes are preventable, and others are curable. We reviewed the records of 5,485 patients who had presented during a 4-year period to the National Ear Care Centre in Kaduna, Nigeria. Of these, we identified 1,435 patients-812 males and 623 females, aged 9 months to 90 years (mean: 29.2 yr)-who had been diagnosed with hearing loss (26.2%). In addition to demographic data, we compiled information on each patient's type and degree of hearing loss, the affected side, and the predisposing factors. Sex and age cross-tabulations revealed that the greatest proportion of hearing loss according to sex occurred between the ages of 11 and 20 years for males and 21 and 30 years for females. The most common type of hearing loss was sensorineural, which was seen in 78.9% of patients; conductive hearing loss was seen in 17.7% and mixed in 3.4%. More than three-quarters of hearing losses were either moderate, moderately severe, or severe. Bilateral losses were far more common than unilateral losses; among the latter, the left side was affected slightly more often than the right. Predisposing factors were not documented in the vast majority of cases (87.6%), but when they were, the most common were chronic suppurative otitis media, meningitis, febrile convulsion, measles, and trauma. We present these findings to highlight the burden of hearing loss in our part of the world. © 2012 Vendome Group, LLC.

Objective: To report the commencement of cochlear implantation (CI) in children in Northern Nigeria and review the challenges encountered with a view to establishing CI programme. Cases: Two children with post-meningitic sensorineural hearing loss had standard pre-implantation assessment and cochlear implantation surgery in Nigeria in conjunction with surgeons from another developing country. Post-implantation meningitis was encountered and managed in one of the patients. Post-CI rehabilitation started in a foreign country and continued in our centre after training of our speech therapist. Both patients had improvement in their hearing. Conclusion: These showcase successful CI in patients from Sub-Saharan Africa, the challenges included need for development of surgical and post-CI rehabilitation personnel and affordability of the cost of the implant. The support of all the stakeholders needed for commencement of a CI programme was noted. © 2013 Elsevier Ireland Ltd.

Introduction: Otitis externa (OE) is an inflammation or infection of the external auditory canal (EAC), the auricle, or both this condition has been reported to be found in all age groups. The aims and objectives were, study/determine the prevalence of Otitis externa in the specialist otolaryngology clinic in National Ear Care Center Kaduna, study the pattern of presentation among patients with otitis externa in the specialist otolaryngology clinic in National Ear Care Center Kaduna, and evaluate the choice of drug treatment for otitis externa in the specialist otolaryngology clinic in National Ear Care Center Kaduna. Methods: Data of patients diagnosed with otitis externa between January 2009 and March 2013 were extracted from the recorded cases of ear disease seen within the same period. The ages, sex/ gender, complains(symptoms), duration of symptoms, clinical examination findings, diagnosis, mode of drug treatment, number of visits and complication records were extracted from the case notes of the patients and analyzed descriptively using SPSS (Statistical package for Social Sciences) version. Results: Out of 13,328 cases of ear diseases seen within the period under review, 133 cases were diagnosed with otitis externa across all age groups. Hospital prevalence stands at 1.0%. There were 81(60.9%) males and 52(39.1%) females in ratio 1.5:1. Children age 0-15 constitute 55(41.3%) while young adults and adults were 78(58.6%). The minimum age at presentation was one year, while maximum age was 64 years. Mean age was 24 years with a standard deviation of ± 1.12 Years. Ear pain as only presenting symptom was the major complain found in this study accounting for 68(51.1%). Acute diffuse otitis externa was the commonest diagnosis accounting for 101(75.9%) and associated clinical findings ranging from tragal tenderness, hyperaemia and oedema of ear canal in 57 (54.9%). Ear swab was not routinely done and only 6(15.8%) of the discharging ears had microscopy done and the organisms were Pseudomonas spp and klebsiella. Empirical treatment was the commonest treatment modality and about 91% of the patients had complete symptom resolution by second visit. Complication was observed in only one case of necrotizing otitis externa who was retro-viral positive. Conclusion: Otitis externa accounted for small fraction of cases seen in our clinic (1%). Acute diffuse otitis externa is the commonest diagnosis made with symptoms ranging from ear pain, ear discharge, hearing loss and itchiness. Most patients were treated empirically with significant success within first two visits. No major complication was recorded within the period under study. © Thomas Samdi Musa et al.
