Background: Otitis media (OM) is a major health problem in both developed and developing countries. Objective: To determine the pattern of bacterial isolates in patients with chronic suppurative otitis media(CSOM) in Ilorin, Nigeria. Methods: A prospective study carried out in University of Ilorin Teaching Hospital, Nigeria among consenting patients with CSOM attending the ENT clinic over a period of 7months. Informed consent was obtained from the patients or caregivers and approval for the study obtained from ethical committee. Structured questionnaire was administered and microbiological analysis done, data obtained was entered into SPSS statistical software and results presented in tables and figures. Results: A total of 134 patients aged 5-64yrs with chronic suppurative otitis media were interviewed with a mean age of 17.0 (S.D. =15.1±1.30). About 55.2% of the respondents were under 10yrs. Seventy-two (53.7%) of the respondents were males with M:F=1.2:1. The gram stain showed predominantly gram negative organisms (71.6%). Pseudomonas aeruginosa was the commonest middle ear pathogenic organism identified and the sensitivity pattern highly favoured ciprofloxacin Conclusion: CSOM is still a childhood problem among the under tens' more prevalent among males and the commonest agent is Pseudomonas aeruginosa. Ciprofloxacin is still the most sensitive antibiotics in vitro.

Eighty-nine cases of head and neck cancers were studied over a 5-year period (1997--2001) at the University of Ilorin Teaching Hospital, Nigeria. The most common cancer affecting the head and neck region was carcinoma which constituted 70.8% of all the cases studied. It was followed by the lymphomas and blastomas which accounted for 20.2% and 9%, respectively. The nose/paranasal sinuses were the most common site of primary cancer (18%) followed by thyroid (12.4%), nasopharynx (11.3%) and larynx (4.5%). Other sites include a hypopharynx (3.4%), eye (2.2%), palate (2.2%), tongue (2.2%), skin (1.1%), lip (1.1%), salivary gland (1.1%), oropharynx (1.1%). Cervical lymph node metastasis with unknown primary lesion was seen in 10.1%. The peak age incidence was in the fifth decade of life. The improvement in locoregional control of head and neck cancers over the last decades does not appear to modify the final survival of these patients. It is crucial to understand as accurately as possible the risk factors for these malignancies in order to improve primary prevention.

Hearing loss is one of the most common chronic health conditions and has important implications for the patient's quality of life. However, hearing loss is substantially underestimated and under treated. The purpose of this study was to determine the prevalence of sensorineural hearing loss among the workers in a steel rolling mill in Nigeria. Each of the 150 randomly selected subjects had a structured questionnaire administered to them, followed by a full otological examination. Of these, 116 had tympanometry and pure-tone audiometry. Also a noise mapping of their respective work units was done. The workers were exposed to noise levels varying from 49 to 93 dBA. About 28.2% of the 103 who had their audiogram analysed had mild to moderate sensorineural hearing loss in their better ear and 56.8% of them had mild to moderate sensorineural hearing loss in their worse ear. The pure-tone average and the average hearing thresholds at 4 kHz for the groups significantly increased with an increasing noise exposure level. The prevalence of sensorineural hearing loss among the study population is high; and noise exposure is at least contributory. Pre-employment and regular audiometry while on the job is highly recommended.

The prevalence of allergic rhinitis using SFAR was 31.6%. The study shows that SFAR can be used as a simple, valid diagnostic tool in allergic rhinitis. This is important in rural settings where access to laboratory investigations might not be readily available.

Deafness, profound hearing loss, is a global problem. However, the causes of, attitudes toward, and management options for deafness differ considerably from region to region. This study seeks to identify the present causes of profound sensorineural hearing loss in Nigeria, which in our environment is almost synonymous to a life sentence of silence and isolation. This is a retrospective survey of children 15 years and below (M = 6.7 years, SD = 3.2). Of the 115 children included in this study, 64 (55.7%) were males, giving a male:female ratio of 5:4. Age group 1-3 years had the highest proportion of hearing loss, 33 (28.7%), and there was a progressive decline in frequency with advancing age. In about a third (34.8%) of patients, causes were unknown, probably congenital. The main acquired causes were febrile illness (18.3%), measles (13.9%), meningitis (8.7%), mumps (6.9%), or severe birth asphyxia (4.3%). Compared to the findings of two decades ago, we conclude that there is no significant shift yet in the etiology of profound sensorineural hearing loss in our environment.
