Prevalence of Age-Related Sensorineural Hearing Loss and Related Factors in Elderly Patients Attending Tertiary Hospital in Tanzania.

PURPOSE: Age-related sensorineural hearing loss (SNHL), is a progressive, usually bilateral hearing loss that occurs in elderly. It is correctable using rehabilitative hearing devices, which can vastly improve the older person's quality of life. This study aimed to find out the prevalence and related factors of age-related sensorineural hearing loss among elderly patients in Tanzania. METHODS: A total of 380 elderly patients who received Otorhinolaryngology (ORL) services at Muhimbili tertiary hospital were enrolled. Participants were screened for hearing loss and interviewed by the structured questionnaire followed by otoscopic examination and Pure tone Audiometry (PTA). RESULTS: This study included 182(47.9%) males, and 198 (52.1%) females. The prevalence of SNHL was 27.6%, males were mostly affected 57(31.3%) p = 0.574. Bilateral SNHL was found 90 (85.7%) p = 0.026, and the severity of age-related SNHL was found to increase as age increases. CONCLUSION: Sensorineural hearing loss among the elderly was prevalent, mostly bilateral, and the severity increases with age. Confounding factors such as hypertension, diabetes mellitus (DM), cigarette smoking, and ototoxic medication may have contributed. Elderly should be screened for hearing loss especially on the individuals with other co-morbidities for early diagnosis and management in order to improve the quality of life of the elderly.

Prevalence of middle ear effusion among children with adenoid hypertrophy at a national referral hospital in Tanzania

Introduction: Middle ear effusion (MEE) is a common childhood disorder that causes hearing impairment due to the presence of fluid in the middle ear which reduces the middle ear's ability to conduct sound. Temporary or persistent hearing loss as a result of MEE causes speech, language and learning delays in children. There are few studies on MEE in Tanzania despite the huge burden of hearing loss among children with adenoid hypertrophy which is a known risk factor for MEE. Method: A cross-sectional study was conducted among 420 children aged nine years and below having adenoid hypertrophy with or without MEE. The diagnosis of adenoid hypertrophy was confirmed with a lateral view x-ray of the nasopharynx and tympanometry for cases with MEE. The primary objective of the study was to assess the prevalence of MEE among children with adenoid hypertrophy. Results: The prevalence of MEE among children with adenoid hypertrophy was 61.7%, with 218 (51.9%) males and 202 (48.1%) females. The most affected age group was 2-4 years with an incidence 193 (46%) and in this age group, males (53.9%) were more affected than females (46.1%). Generally, males, 134 (51.7%) were more affected by MEE than females, 125 (48.3%) of all 259 children with MEE. In terms of age group predominance by MEE, children aged 3-4 years, 107(41.3%) were more affected than all other age groups. Additionally, 4 (1.5%) children with MEE presented with hearing loss. Conclusion: There is a high prevalence of MEE among children with adenoid hypertrophy but no significant association with hearing loss.

Spontaneous expulsion of an intrabronchial sharp metallic foreign body and migration to the gastrointestinal tract at Muhimbili National Hospital: Case report and literature review.

INTRODUCTION: Aspirated foreign bodies continue to pose challenges to Otorhinolaryngologists and are potentially life threatening thus an otorhinolaryngological emergency. The main stay of treatment of foreign bodies (FBs) in the tracheobronchial tree remains to be bronchoscopy while bearing in mind earlier and safer removal of such foreign bodies. Spontaneous expulsion of an Intrabronchial foreign body is a rare entity with few cases reported in the available literatures. PRESENTATION OF CASE: We are reporting a rare case of a 3-year old male child who presented to otorhinolaryngology department with a 2-days history of foreign body inhalation (sharp metallic pin) prior admission which undergone spontaneous migration and went to be excreted in feaces after passing through the gastrointestinal tract. DISCUSSION: It is unwise, dangerous and inadvisable to wait for spontaneous expulsion in cases of intrabronchial foreign body but while preparing for endoscopy, a constant watch should be kept over the patient and every forceful bout of cough should be looked with suspicion of spontaneous expulsion and a danger of foreign body lodgment into subglottis during such rare but possible occurrence should be kept in mind. CONCLUSION: It's always worth to rule out the possibility of foreign body inhalation in children with sudden onset of difficulty in breathing to avoid diagnostic delays.

Prevalence and etiological agents for chronic suppurative otitis media in a tertiary hospital in Tanzania.

OBJECTIVE: Chronic suppurative otitis media is among the most common otological condition reported in otorhinolaryngology practice commonly attributing to preventable hearing loss. The aim of this study was to determine the prevalence and etiological agents for chronic suppurative otitis media in our department. RESULTS: A total of 5591 patients were recruited in this study and only 79 (1.4%) had chronic suppurative otitis media. A male preponderance 43 (54.4%) was noted in this study and the left ear (58.2%) was more commonly affected compared to the right ear. Central perforation was the commonest pattern of presentation and was reported in 53% of cases though none had attic perforation. Of the 81 processed ear swabs, microbial growth was seen in majority 80 (98.8%) whilst one sample showed no microbial growth whereas 52.5% had polymicrobial growth. Among the isolates, most were gram negative species accounting for 59.7% while gram positive bacteria accounted for 25.6% and fungi accounted for 14.7%. Most of these isolates were facultative anaerobes. Klebsiella pneumoniae (20.2%) was the commonest isolates while Escherichia coli and Pseudomonas aeruginosa were equally least isolated (10.9%). Tested isolates were most sensitive to Ciprofloxacin, Gentamycin, Ceftriaxone and Amikacin and least sensitive to Amoxicillin/clavulanic acid and Ampicillin.

Pattern and causes of tympanic membraneperforation at a private hospital in Dar es Salaam, Tanzania

Introduction: There is variation in the size, shape and position of tympanic membrane perforations; the degree of conductive hearing loss depends on the size and position of perforation.Objective: To determine the pattern and causes of tympanic membrane perforation at a private health facility in TanzaniaMethod: A hospital-based cross-sectional study in the ENT clinic at Ekenywa Specialised Hospital was conducted from January to May 2019. Ears were examined thoroughly by an Otorhinolaryngologist. Data were analysed using SPSS Version 21Results: Two hundred and fifty patients were examined and 50 (20%) were found to have tympanic membrane perforations. Thirty (60%) were new patients while twenty (40%) were under review. Most 35(70%) were males. Central perforation predominated in 30 (60%), followed by subtotal in 10 (20%), total in 8 (16%) and marginal perforations in 2 (4%). The left ear was more affected in (60%) than the right ear. Bilateral perforations accounted for 5 (10%) of cases. Chronic suppurative otitis media was found in 35 (70%); other causes were acute suppurative otitis media in 13 (26%) and trauma in 2 (4%) patientsConclusions: The clinical picture depicted in this study is similar to that found elsewhere. There is a need for prompt diagnosis of tympanic membrane perforation. Proper education on ear care in patients with perforated tympanic membrane is of paramount importance
