RESUMO
Noise is a global occupational and environmental health hazard with considerable social and physiological impact and, therefore, there is a need for regular measurements to boost monitoring and regulations of environmental noise levels in our communities. This necessitates a readily available, inexpensive, and easy to use noise measuring device. We aimed to test the sensitivity and validity of mobile "smart" phones for this purpose. This was a comparative analysis of a cross sectional study done between January 2014 and February 2015. Noise levels were measured simultaneously at different locations within Abuja Nigeria at day and night hours in real time environments. A sound level meter (SLM) (Extech407730 Digital Soundmeter, serial no.: 2310135, calibration no: 91037) and three smartphones (Samsung Galaxy note3, Nokia S, and Techno Phantom Z running on Android "Apps" Androidboy1) were used. Statistical calculations were done with Pearson correlation, T-test and Consistency within American National Standards Institute acceptable standard errors. Noise level readings for both daytime and night with the SLM and the mobile phones showed equivalent values. All noise level meters measured were <100dB. The daytime readings were nearly identical in six locations and the maximum difference in values between the SLM and Smartphone instruments was 3db, noted in two locations. Readings in dBA showed strong correlation (r = 0.9) within acceptable error limits for Type 2 SLM devices and no significant difference in the values (p = 0.12 & 0.58) for both day and night. Sensitivity of the instrument yielded 92.9%. The androidboy1 "app" performance in this study showed a good correlation and comparative high sensitivity to the Standard SLM (type 2 SLM device). However there is the need for further studies.

Delivery of health services to people with hearing impairment is poorly understood in Nigeria and limited research has been done to throw more light on the process involved. This study described experiences of 167 girls with hearing impairment in accessing reproductive health services in Ibadan using a validated questionnaire. Descriptive statistics and binary logistic regression were used to analyze the data. Almost 95.0% of respondents had ever visited health facility for reproductive health issues. Of these 6.2% and 4.6% went for treatment of STIs and pregnancy termination respectively; 36.7% were embarrassed to ask questions in the presence of an interpreter, communication (40.5%) and cost (10.8%) were key barriers to access and 85.6% would use facility if hearing impairment-friendly services are provided. Respondents who were currently working were 20 times more likely to receive services they wanted (OR = 20.29, CI = 1.05-392.16). Availability of certified interpreters and ensuring confidentiality are key to effective service delivery for the hearing impaired.

Introduction: Disabling hearing loss as a sequela of bacterial meningitis results from damage to the auditory system. This study was designed to ascertain the hearing thresholds in survivors of bacterial meningitis and the risk factors of hearing loss in childhood bacterial meningitis. Methodology: One hundred and two children admitted and treated for bacterial meningitis were recruited prospectively along with 102 age- and sex-matched controls who had auditory evaluation using otoacoustic emission and auditory brain stem response tests 48 h prior to hospital discharge. This was also repeated at the follow-up clinic at 1 month after hospital discharge, irrespective of the initial hearing assessment results. Result: There were 57 (55.9%) males and 45 (44.1%) females among the cases (mean age, 5.34 ± 4.40 years) and 55 (53.9%) males and 47 (46.1%) females among the controls (mean age, 5.31 ± 3.15 years). The prevalence of hearing loss was 30.4% among the cases, while it was 6.9% among the controls. The risk factors of hearing impairment in this study were the presence of anemia, leukocytosis, and hypoglycorrhachia. Conclusion: Hearing impairment with varying degrees of severity is a frequent complication of bacterial meningitis in children.
RESUMO
BACKGROUND: It is recognized that the size of tympanic membrane perforation is proportional to the magnitude of hearing loss, however, there is no clear consensus on the effect of the location (site) of the perforation on the hearing loss. Hence the study is set to investigate the relationship between the location of perforation on TM and hearing loss. METHODS: A cross-sectional prospective study of consecutive adult patients with perforated TM conducted in the ENT clinic of University College Hospital Ibadan between January 1st 2005 and July 31st 2006. Instruments used for data collection/processing include questionnaires, video and micro-otoscopy, Pure tone audiometer, image J and SPSS packages. RESULTS: Sixty-two patients (22-males, 40-females), aged 16-75 years (mean = 35.4 +/- 4) with 77 perforated ear drums were studied and 15(24.2%) had bilateral TM perforations, 21 (33.9%) right unilateral and 26(41.9%) left unilateral. The locations of the TM perforations were 60(77.9%) central, 6(9.6%) antero-inferior, 4(5.2%) postero-inferior, 4(5.2%) antero-superior and 3(3.9%) postero-superior respectively with sizes ranging from 1.51%-89.05%, and corresponding hearing levels 30 dB - 80 dB (59% conductive and 41% mixed). Fifty-nine percent had pure conductive hearing loss and the rest mixed. Hearing losses (dBHL) increased with the size of perforations (P = 0.01, r = 0.05). Correlation of location of perforations with magnitude of hearing loss in acute TM perorations was (P = 0.244, r = 0.273) and for chronic perforations (p = 0.047 & r = 0.31). CONCLUSION: The location of perforation on the tympanic membrane (TM) has no effect on the magnitude of hearing loss in acute TM perforations while it is significant in chronic ones.
RESUMO
BACKGROUND: Some variants of migraine could be indistinguishable from Meniere's disease, and this has prompted suggestions of possible association between the two disease entities. AIM AND OBJECTIVES: This study aims at determining the prevalence of migraine among Meniere's patients and a possible linkage between the two diseases in our environment. METHODOLOGY: A 10-year retrospective study of patients diagnosed with Meniere's disease using American Academy of Otorhinolaryngology criteria, including those that had associated migranous symptoms in accordance with the International Headache Society (IHS) diagnostic criteria for migraine, between 1996 and 2005. The prevalence of migraine in the Meniere's patients was also compared with lifetime prevalence recorded from a previous population-based study within the same setting. The statistical difference was tested with a Z nonparametric test (significance at P < 0.05). Epicalc2000 and SPSS 11 were used for the statistical analysis. RESULT: A total of 25 patients representing 0.22% of the 11,463 ear, nose and throat outpatients seen within the study period met the diagnostic criteria for Meniere's disease. There were nine (36%) males and 16 (94%) females. Their ages ranged 27-65 years, mean 45.25 years +/- 11.05. Eight (32%) met IHS criteria for migraine. There is a statistically significant difference between the prevalence of migraine in Meniere's patients and migraine in the overall population (32% vs. 5.3%, P = 0.000). CONCLUSION: The significant preponderance in the prevalence of migraine in Meniere's disease suggests a link between the two diseases. However, more molecular or genetic studies are needed to unveil this phenomenon.

CONTEXT: The knowledge of variations of the tympanic membrane (TM) perforations with the climatic changes in the West African subregion would help clinicians in its prevention and management. OBJECTIVE: To analyze the pattern of clinical presentations and associated features of TM perforation in adults in West Africa. DESIGN: A prospective study. SETTING: Tertiary referral centre, University hospital. PATIENTS OR OTHER PARTICIPANTS: Thirty-five (35) consecutive adults with TM perforations during a 1-year period had clinical evaluation of each TM using head mirror, video otoscopy, and micro-otoscopy. MAIN OUTCOME MEASURES: Clinical presentations and associated features of TM perforations. RESULTS: Thirty-five patients, 20 (57%) men and 15 (43%) women, with 42 perforated TMs were examined. Twenty-eight (80%) patients had unilateral perforations. Infection was responsible for 90.5% of cases, and trauma was responsible for the rest. Locations of perforations were central (29; 69.1%), anteroinferior (4; 9.5%), posteroinferior (4; 9.5%), anterosuperior (3; 7.1%), and posterosuperior (2; 4.8%). The sizes of the perforations ranged from 1.2 to 83.2%. Large sizes of 25% and more were found to occur in humid and wet seasons, and also, clinical presentations of otorrhea (65.6%), otalgia (51.5%), tinnitus (37.1%), and ear itching (34.4%) seemed to worsen. CONCLUSION: Most TM perforations result from infection and are preventable via appropriate health education. Posterosuperior perforation is rare, and this is probably one of the factors making choleasteatoma uncommon in West Africa. Approximately 83.3% of TM perforations measure more than 25% in size and appear during the wet humid season of the year. These findings are important for both local and foreign otolaryngologists who may be practicing in this subregion of the world.

BACKGROUND: Teratoma is a rare developmental neoplasm that arises from totipotential tumor stem cells. Head and neck teratomas constitute about 10% of all cases. Only two cases of mature teratoma of the nasal septum have previously been documented in the world literature. CASE PRESENTATION: We present a case of histologically confirmed mature teratoma arising from the nasal septum in an eighteen month old Nigerian female who presented with a history of noisy breathing associated with recurrent rhinorrhea since birth. Physical examination revealed obstruction of the right nasal cavity by a pale fleshy mass. She underwent a total surgical excision and to date, after thirty one months follow-up, she is free from recurrence. CONCLUSION: The prognosis for benign teratoma of the nasal septum is good following total surgical excision.

OBJECTIVE: The aim was to assess the psychosocial effects on the quality of life (QOL) of adults with head and neck cancer (HNC) and any gender variations with predictive factors that may influence QOL. PATIENTS AND METHODS: This was a three-month descriptive and prospective evaluation of QOL in 50 adult patients with HNC who were still on treatment but had spent a period of at least four weeks from commencement in a tertiary hospital. MAIN OUTCOME RESULTS: There were 32 males and 18 females with a mean age of 47.74 years. Females had higher mean scores than males in all domains except pain domain, global and general questions. There was no significant difference in the mean score between the genders in all the domains: overall bother, overall satisfaction, response to treatment, site with QOL and health-related QOL (HRQOL). Pain domain correlated significantly with eating and emotion but weakly with stage of the disease. The predictive factor for overall bother was mainly emotion domain, while site of lesion with QOL was for overall satisfaction, response to treatment and HRQOL. CONCLUSIONS: Pain, which is a major problem experienced by these patients with HNC, requires more attention by the caregiver in order to improve their QOL.

OBJECTIVES: This study aims to highlight the problems associated with impacted acrylic dentures and proffers advice to check them. PATIENTS AND METHODS: Retrospective review of all cases of impacted acrylic dentures over a 16-year period. RESULTS: Twenty-two adults had impacted esophageal acrylic dentures of which 16 (72.7%) and six (27.3%) were males and females, respectively (M:F ratio = 2.7:1) with age range 23-77 years. Fourteen patients (63.6%) had worn their dentures for more than 10 years without check-up, and 54.5% presented within 48 hours of impaction. The common symptoms in all the patients were difficulty with swallowing, throat pain and discomfort, followed by tenderness in the neck in 15 (68.2%). Dentures were extracted through esophagoscopy (17 cases) and cervical (three cases) esophagotomy, respectively. Observed complications included pulmonary edema in one and esophageal perforation in five patients. CONCLUSION: Endoscopic extraction of dentures carries a high risk of perforation. Extraction of an impacted denture via esophagoscopy can be undertaken under direct vision and in an ideal situation with judicious use of the Shears forceps. In the absence of these, the safest option is an esophagotomy. Proper treatment planning in the fabrication of dentures with incorporation of radiopaque materials in the dental resins and adequate postdenture delivery instructions are necessary as preventive measures.

The hemoglobin (Hb) SC genotype is seen in persons who have inherited the gene for hemoglobin S from one parent and the gene for hemoglobin C from the other. Some people with this genotype develop Hb SC disease, a variant of sickle cell disease. Hb SC disease, a compound heterozygous condition, is the most common of the hemoglobinopathies and the least severe, although it is still serious. One of the documented complications of the presence of the Hb SC genotype is sensorineural hearing loss (SNHL). We conducted a prospective case-control study of 43 subjects, aged 15 to 65 years, who had the Hb SC genotype to determine the incidence of SNHL and to determine if the hearing loss in these subjects was correlated with sex or age. Our control group was made up of 100 generally healthy, sex- and age-matched subjects with the normal Hb AA genotype. SNHL was defined as a loss of more than 25 dB HL at two or more frequencies in the same ear or at one or more frequencies in both ears. We found that SNHL was present in 12 of the 43 subjects (27.9%) in the Hb SC group (17 of 86 ears [19.8%]) and in 17 of the 100 subjects (17.0%) in the Hb AA group (21 of 200 ears [10.5%]; the difference between the two groups was not statistically significant (chi(2) = 1.589; p = 0.105). We found that in the Hb SC group, SNHL was more common among females than males (38.5 vs. 11.8%), although the difference was not quite significant statistically (chi(2) = 2.435; p = 0.056); in the Hb AA group, the incidence was fairly equal-15.4 and 18.8%, respectively (chi(2) = 0.033; p = 0.427). Therefore, we conclude that the hearing loss in the subjects of this study was not correlated with the presence of the Hb SC genotype in either sex. In terms of age, SNHL was significantly more common in subjects aged 41 to 65 years than in those aged 15 to 40 years in both genotype groups. In the Hb SC group, SNHL was present in 4 of the 33 younger subjects (12.1%) and in 8 of the 10 older subjects (80.0%) (chi(2) = 14.354; p < 0.001). In the Hb AA group, the corresponding figures were 7 of 85 (8.2%) and 10 of 15 (66.7%) (chi(2) = 26.840; p < 0.001). Therefore, we conclude that the hearing loss in the subjects of this study was a function of age and was not associated with the presence of the Hb SC genotype.

Most ingested foreign bodies in the aero-digestive tracts in both children and adults are not radio-opaque, and as a result, a preoperative plain radiograph may not be helpful. However, incorporating radio-opaque markers into such potential foreign bodies like toys, beads, and dentures during manufacture (as illustrated in this case of a 6-year-old boy who ingested a piece of glass mirror which was easily seen on X-ray) would obviate this problem. While this may constitute some financial burden on manufacturers, the cost effectiveness on health management is non-negotiable. We suggest that appropriate authorities and regulatory bodies should enforce this through legislation.

We conducted a study to determine how accurate various ENT specialists were in estimating the size of 100 tympanic membrane (TM) perforations with standard otoscopy. The specialists included, in descending order of rank, 2 Consultant Surgeons, 2 Senior Registrars, and 2 Registrars, all of whom had confirmed good vision. We compared their estimates, which were made independently and expressed as a percentage of the total area of the TM, with exact measurements calculated with computer-based video-otoscopy. We found that the video-otoscopic calculations were far superior to the estimates of the specialists, even the most experienced Consultants (p < 0.01). We recommend that video-otoscopy be used whenever possible.

OBJECTIVE: To highlight the importance of a high index of suspicion and meticulous evaluation of a patient with bleeding sinonasal mass in the diagnosis of sinonasal paraganglioma. METHOD: Case report of a 39-year-old female who presented with a bleeding lobulated left nasal mass necessitating multiple blood transfusions is presented. RESULT: Diagnostic investigations revealed that the patient was HIV-positive (ELISA and Western blot) and a tumour histology of paraganglioma. She had a CD4+ count of 487 cells/mm3. The urinary vanillylmandelic acid assay and echocardiography were normal. Subsequently, she had complete tumour excision through a medial maxillectomy and has remained without a recurrence 12 months after. CONCLUSION: To our knowledge, this is the first report in the world literature of sinonasal paraganglioma in a HIV-positive patient and the first reported case of sinonasal paraganglioma in Africa. It is, however, not clear from this report if the patient's HIV status preceded her development of the paraganglioma or not.
