Update on first African clinical trial on earpopper for the treatment of otitis media with effusion [FCT/UATH/HREC/PR/330].

Background: Otitis media with effusion (OME) is a middle ear condition characterized by the accumulation of serous fluid. It is common, though not exclusive; among children with its attendant developmental consequence if missed or untreated in early life. OME could be managed surgically, pharmacologically, or physiologically. EarPopper is a medical device developed for physiologic management of OME, Eustachian tube dysfunction, and related problems. We aim to ascertain the suitability/efficiency of EarPopper® device for the treatment of OME in our setting. Methodology: This is a prospective interventional study of volunteers diagnosed with OME from four (4) medical centers in Abuja. Pneumatic otoscopy, video-otoscopy, tympanometry, and pure-tone audiometry were done to confirm the diagnosis. Serial EarPopper sessions were performed twice weekly for 2-12 weeks, and outcome was assessed using patients' reports. The reports include the EarPopper scoring system (ESS) and audiometric parameters (before and after therapy). Results: Forty-five patients (17 males and 28 females) aged between 3-56 years were enrolled. Thirty-five were diagnosed with bilateral OME and 10 unilateral. All patients had Type-B tympanometry tracing with mild-to-moderate conductive hearing losses and ESS of between 2.45% and 84%. Out of the 45 participants, 32 (71.1%) completed the treatment, whereas 13 (28.9%) were lost to follow-up. Duration of EarPopper treatment ranged from 2 to 12 weeks. The outcome revealed improvement in 26/32 (81.3%) with significant reduction in ESS (1% to 9.8%). Six patients 6/32 (18.9%) had persistence symptoms. These 18.9% had the propensity to progress to chronic OME. Conclusion: This study highly suggests good prospect in using EarPopper for the management of OME among Africans.

Résumé Contexte: L'otite séreuse est une affection de l'oreille moyenne caractérisée par l'accumulation de liquide séreux. Cette condition est courante chez les enfants (mais pas exclusivement) avec des conséquences développementales qui s'élabore si la diagnostique est manquées ou non traitées pendant les premières années de vie. L'otite séreuse peut être prise en charge chirurgicalement, pharmacologiquement ou physiologiquement. " EarPopper " est un appareil médical développé pour la gestion physiologique de l'otite séreuse, du dysfonctionnement de la trompe d'Eustache et des problèmes associés. Nous visons à déterminer la convenance/l'efficacité de l'appareil EarPopper® pour le traitement de l'otite séreuse dans notre environnement. Méthodologie: Il s'agit d'une étude interventionnelle prospective sur des volontaires ayant reçu un diagnostic de l'otite séreuse dans quatre (4) centres médicaux à Abuja. Une otoscopie pneumatique, une vidéo-otoscopie, une tympanométrie et une audiométrie tonale ont été réalisées pour confirmer le diagnostic. Des sessions EarPopper® en série ont été effectuées deux fois par semaine pendant 2 à 12 semaines, et les résultats ont été évalués à l'aide des rapports des patients. Les rapports incluent le système de notation EarPopper® (ESS) et les paramètres audiométriques (avant et après la thérapie). Résultats: Quarante-cinq patients (17 hommes et 28 femmes) âgés de 3 à 56 ans ont été inclus. Trente-cinq ont reçu un diagnostic de l'otite séreuse bilatérale et 10 unilatérales. Tous les patients avaient un tracé tympanométrique de type B avec des pertes auditives de transmission légères à modérées et une ESS comprise entre 2,45 % et 84 %. Sur les 45 participants, 32 (71,1 %) ont terminé le traitement, tandis que 13 (28,9 %) ont été perdus de vue. La durée du traitement EarPopper® variait de 2 à 12 semaines. Les résultats ont révélé une amélioration dans 26/32 patients (81,3%) avec une réduction significative de l'ESS (1% à 9,8%). Six patients (6/32 ; 18,9 %) on présentaient avec des symptômes persistants. Ces 18,9% avaient une propension à évoluer vers une otite séreuse chronique. Conclusion: Cette étude suggère fortement de bonnes perspectives d'utilisation d'EarPopper® pour la gestion de l'otite séreuse chez les Africains. Mots-clés: EarPopper®, l'otite séreuse, tympanométrie.

Hearing Thresholds among Individuals with Dependence on Psychoactive Substances: A Comparative Cross Sectional Pilot Study.

Background: Globally, the use of multiple psychoactive substances (MPS), either together or at different times, is on the rise. It is associated with a significant public health burden, including an increased risk for hearing impairment. This study aimed to determine the hearing thresholds among individuals with dependence on multiple psychoactive substances. Methodology: It was a comparative cross-sectional study of 41 subjects with dependence on multiple substances and an equal number of age and sex-matched comparison groups. The test group further had three subgroups, based on their predominant substances of dependence; Group I: Cigarettes, Cannabis, and Codeine; Group II: Group I substances and intravenous Pentazocine. Group III: Group II substances and intravenous Ketamine. Specific Substance Involvement scores for each of the psychoactive substances and their associated level of risk were determined, based on the ASSIST V3 questionnaire. All participants had tympanometry and pure tone audiometry. A Pure Tone Average (PTAv) was calculated. Data were analysed using SPSS 25 and statistical significance was set at a p-value 0.05. Results: There were 36 (87.8%) males and 5 (12.2%) females. The mean age of the test and comparison groups was 27.93 5.47 years and 27.98 5.70 years (p = 0.969). The mean PTAv of the test and comparison groups were 16.07 ± 5.53 dBHL and 11.01± 3.52 dBHL: (p 0.001). The p-value for the difference in the mean PTAv between sub-groups of the test group was 0.173, 0.037, and 0.719, respectively, between Group I and II, Group I and III, and Group II and III, respectively. Conclusion: Hearing thresholds were higher among individuals with dependence on MPS and statistically significant in those that were dependent on cigarettes, cannabis, and codeine. Further studies are needed on the relationship between PS and hearing loss.

Tympanometric findings among Nigerian prison inmates: A cross-sectional survey.

BACKGROUND: Prisoners, due to confinement, are isolated from contact with society and access to many of the facilities, including medical care. There is paucity of data on the middle ear function of prison inmates in the English literature globally. We aimed to assess the middle ear function of prison inmates in Kaduna, Nigeria. PARTICIPANTS AND METHODS: This was a cross-sectional comparative study of prison inmates at the Kaduna convict prison. Ethical approval was obtained from the Kaduna State Ministry of Health and the Nigerian Prison Service. Prison inmates aged 18-55 years in the Kaduna convict prison with an equal number of age and sex-matched controls from the community were enrolled. Consent was obtained from the participants. Data were collected using a structured pre-tested questionnaire. Participants had a thorough physical examination of the ears. Tympanometry was conducted on suitable participants to assess the middle ear function. Statistical Product and Service Solutions version 20.0 was used to analyse the data. RESULTS: Four hundred and thirty inmates with an equal number of controls were enrolled for the study. The mean age for the inmates and controls was 30.2 ± 7.51 and 30.4 ± 8.02 years, respectively. There were 47 female and 383 males, with a female: male of 1:8.1. Forty-six (46/397, 11.6%) of the inmates and 15 (15/423, 3.5%) of the controls had abnormal tympanograms on the right while on the left, it was 12.4% and 3.8%, respectively. The difference between the two groups was statistically significant (χ2 = 40.071, P = 0.0001). CONCLUSION: : Middle ear abnormalities are more prevalent among prison inmates than the general population. Middle ear effusion and ossicular chain disruption were the most common middle ear abnormalities affecting the prison inmates.
