Hearing impairment among chronic kidney disease patients on haemodialysis at a tertiary hospital in Ghana

Background: Chronic kidney disease is a major public health challenge, globally. Inadequate excretion of metabolic waste products by the kidneys results in circulation of these toxic materials in the body. This can cause damage to tissues and organ systems including the auditory system which can lead to hearing loss.Aim: The study was aimed at determining the prevalence, degrees and types of hearing impairment among Chronic kidney disease patients on haemodialysis in Ghana.Methods: A case-control study involving 50 Chronic Kidney disease patients and 50 age and gender-matched control group was carried out at the Korle Bu Teaching Hospital (KBTH). A structured questionnaire was administered to obtain basic socio-demographic data and case history of the participants. Audiological assessment was performed using a test battery comprising otoscopy, tympanometry and pure tone audiometry in a soundproof booth.Results: Higher hearing thresholds were recorded across all the frequencies tested among the case group than the control group (p < 0.05) in both ears. Only sensorineural hearing loss was identified among the cases. The prevalence of hearing loss was 32% among the case group and 12% among the control group. No significant association was observed between hearing loss and duration of Chronic kidney disease (p = 0.16), gender of Chronic kidney disease patient and hearing loss (p = 0.88), and duration of Chronic kidney disease and degree of hearing loss (p=0.31).Conclusion: Our study showed that Chronic Kidney disease patients on haemodialysis are at higher risk of experiencing hearing loss.Keywords: Hearing loss, chronic kidney disease, prevalence, haemodialysis, hearing thresholdFunding: None declare

An assessment of indoor radon level in a suburb of Ghana

Abstract Radiation and radioactive isotopes form part of our natural environment. Elevated levels of these radioactive isotopes in the environment can pose a threat to our health. A greater proportion of the natural radiation is from the radioactive gas radon. Although it cannot be detected by human senses, radon and its progenies are of health concern as it can cause lung cancer when inhaled over a period of time. This study sought to provide baseline indoor radon data, the life time risk of lung cancer and its interpretation within a suburb of Ghana. Solid State Nuclear Track Detector (LR-115 type II) was deployed in 82 homes within a suburb for a period of three months (September 2017- January 2018). Indoor radon concentration (IRC) for the suburb was within the range of 4.1�176.3 Bq m?3. With mean 57 ± 39 Bq m?3. The mean radon exposure to the dwellers was recorded as 0.12 ± 0.08 WLMy?1 resulting in 0.7 ± 0.5 mSvy?1 effective dose to the lung with an excess lifetime cancer risk of 0.39 ± 0.26%. There was a positive correlation between indoor radon concentration and the building type and the association was significant with a P value of 0.047.</jats:p
