The programming of CIs is essential for good performance. However, no Good Clinical Practice guidelines exist. This paper reports on the results of an inventory of the current practice worldwide. A questionnaire was distributed to 47 CI centers. They follow 47600 recipients in 17 countries and 5 continents. The results were discussed during a debate. Sixty-two percent of the results were verified through individual interviews during the following months. Most centers (72%) participated in a cross-sectional study logging 5 consecutive fitting sessions in 5 different recipients. Data indicate that general practice starts with a single switch-on session, followed by three monthly sessions, three quarterly sessions, and then annual sessions, all containing one hour of programming and testing. The main focus lies on setting maximum and, to a lesser extent, minimum current levels per electrode. These levels are often determined on a few electrodes and then extrapolated. They are mainly based on subjective loudness perception by the CI user and, to a lesser extent, on pure tone and speech audiometry. Objective measures play a small role as indication of the global MAP profile. Other MAP parameters are rarely modified. Measurable targets are only defined for pure tone audiometry. Huge variation exists between centers on all aspects of the fitting practice.

Purpose The aim of this study was to assess the proportion of patients seen in a tinnitus and hyperacusis therapy clinic for whom presentation levels based on the British Society of Audiology (BSA)–recommended procedures for pure-tone audiometry and determination of uncomfortable loudness levels (ULLs) exceed ULLs, leading to discomfort during administration of these procedures. Method This was a retrospective cross-sectional study of 362 consecutive patients who attended a National Health Service audiology clinic for tinnitus and/or hyperacusis rehabilitation. Results For 21% of the patients, presentation levels based on the BSA procedure for pure-tone audiometry exceeded the ULL for at least 1 of the measured frequencies (excluding the first frequency tested, 1 kHz): 0.25, 0.5, 2, 3, 4, 6, and 8 kHz. For 24% of patients, the starting presentation level of 60 dB hearing level recommended for determination of ULLs exceeded the ULL for at least 1 frequency. Conclusion The starting presentation levels used for pure-tone audiometry and measurement of ULLs should be lower than those recommended by the BSA for people with tinnitus and hyperacusis.

Introduction: The Hum Test is used by some otolaryngologists as an alternative to the Weber Test to detect the presence and type of acute hearing change; however, its use has not yet been formally validated. Objective: To compare the diagnostic performance of Hum test with Weber test to detect hearing loss taking pure tone audiometry as the gold standard. Methodology: A prospective, cross-sectional study was conducted in the department of Otorhinolaryngology and Head and Neck surgery, Dhulikhel Hospital- Kathmandu University Hospital, from June 2018 to February 2019. Total of 257 patients were enrolled in the study and were subjected to 3 tests: Weber test, Hum test, and pure tone audiometry. Results: When examining patients with hearing loss, sensitivity of Hum test and weber test were 60.3% and 93.8 % respectively. In patients with CHL, sensitivity of Hum test was 55.7% while Weber test was 94.8%. In SNHL, it was 74.6% for Hum test and 90.5% for Weber test. Likewise, according to laterality of disease, sensitivity of Hum test was 58.6% for unilateral hearing loss and 65.2% for bilateral hearing loss. For Weber test it was 96.3% for unilateral and 86.4% for bilateral disease. Conclusion: Hum test is not as sensitive as Weber test in diagnosis of hearing loss both for conductive and sensorineural hearing loss.

Epidemiological Characteristics

ObjectiveTo evaluate the self-reported history of concussion in athletes of both Brazilian Jiu-Jitsu (BJJ) and Muay Thai.BackgroundCombat sports are widely practiced around the world. They include modalities that involves punches or kicks directed at the opponent's head (Striking sports) or that consists of grabbing an opponent and taking him to the ground (Grappling sports). Due to the objectives and close contact in combat sports, the risk of concussion is significant.Design/MethodsThis was a cross-sectional study involving a Brazilian sample of BJJ athletes (n-18) and Muay Thai athletes (n-22). The sample was consisted of both professional and amateur athletes (Women constituted 20% of sample). Through individual interviews with a researcher the following data were collected: self-report of concussion and the moment of the injury (whether in practice or in the fight). The Post-Concussion Symptoms Scale (PCSS) was also applied. In the present study, a concussion was considered as a direct impact on the head followed by symptoms. This study was approved by a local Ethics Committee.ResultsAmong BJJ athletes, 61% reported a history of concussion, while among Muay Thai athletes the percentage was more higher (86%). The main mechanisms of head impact were the throw/takedown and elbow-hits to the head in BJJ and punches and knee-hits to the head in Muay Thai. There was no difference in the symptom score between BJJ and Muay Thai concussed athletes (average of 11 vs 10.7, respectively). The most common symptoms were dizziness, headache and nausea in BJJ athletes, and headache, nausea, drowsiness and brain fogginess in Muay Thai ones.ConclusionsThe results presented herein suggest that concussions in Muay Thai and BJJ occur through different mechanisms. The clinical profile of post-concussion symptoms appears to be different between BJJ and Muay Thai athletes.

ABSTRACT Objective To assess central auditory function in Friedreich's ataxia. Methods A cross-sectional, retrospective study was carried out. Thirty patients underwent the anamnesis, otorhinolaryngology examination, pure tone audiometry, acoustic immittance measures and brainstem auditory evoked potential (BAEP) assessments. Results The observed alterations were: 43.3% in the pure tone audiometry, bilateral in 36.7%; 56.6% in the BAEP test, bilateral in 50%; and 46.6% in the acoustic immittance test. There was a significant difference (p < 0.05) in the comparison between the tests performed. Conclusion In the audiological screening, there was a prevalence of the descending audiometric configuration at the frequency of 4kHz, and absence of the acoustic reflex at the same frequency. In the BAEP test, there was a prevalence of an increase of the latencies in waves I, III and V, and in the intervals of interpeaks I-III, I-V and III-V. In 13.3% of the patients, wave V was absent, and all waves were absent in 3.3% of patients.

To examine the incidence of contamination and current practice of decontamination of nebulisers after use within a ventilator circuit, in public- and private sector intensive care units (ICUs) in Johannesburg; to assess the presence of and adherence to a decontamination protocol in these ICUs and to identify which practices were associated with lower or no bacterial growth. Methods: A cross-sectional study design was used which included a semi-structured interview with the ICU manager and an audit of current nebuliser practice. Nebulisers that were identified in the interview were swabbed and streaked on blood agar plates (BAPs). BAPs were incubated and assessed for bacterial colonisation, number of colony forming units (CFUs) and number of different species of CFUs present. Results: Two hundred and sixty-nine ICU beds were surveyed over a two-month period resulting in 45 nebulisers used within a ventilator circuit that could be tested. The majority (93%) were single-use jet nebulisers, all were being re-used and 52% presented with contamination. None of the ICUs had a nebuliser decontamination protocol in place. Contaminated nebulisers that were stored in a sterile drape had significantly higher concentrations of bacterial growth (p=0.03). Conclusion: The rate of colonisation of re-used jet nebulisers is high. Nebuliser decontamination protocols are urgently needed.

Background Sudden sensorineural hearing loss (SSNHL) is an otologic emergency that warrants urgent management. Pure-tone audiometry remains the gold standard for definitively diagnosing SSNHL. However, in clinical settings such as primary care practices and urgent care facilities, conventional pure-tone audiometry is often unavailable. Objective This study aimed to determine the correlation between hearing outcomes measured by conventional pure-tone audiometry and those measured by the proposed smartphone-based Ear Scale app and determine the diagnostic validity of the hearing scale differences between the two ears as obtained by the Ear Scale app for SSNHL. Methods This cross-sectional study included a cohort of 88 participants with possible SSNHL who were referred to an otolaryngology clinic or emergency department at a tertiary medical center in Taipei, Taiwan, between January 2018 and June 2019. All participants underwent hearing assessments with conventional pure-tone audiometry and the proposed smartphone-based Ear Scale app consecutively. The gold standard for diagnosing SSNHL was defined as the pure-tone average (PTA) difference between the two ears being ≥30 dB HL. The hearing results measured by the Ear Scale app were presented as 20 stratified hearing scales. The hearing scale difference between the two ears was estimated to detect SSNHL. Results The study sample comprised 88 adults with a mean age of 46 years, and 50% (44/88) were females. PTA measured by conventional pure-tone audiometry was strongly correlated with the hearing scale assessed by the Ear Scale app, with a Pearson correlation coefficient of .88 (95% CI .82-.92). The sensitivity of the 5–hearing scale difference (25 dB HL difference) between the impaired ear and the contralateral ear in diagnosing SSNHL was 95.5% (95% CI 87.5%-99.1%), with a specificity of 66.7% (95% CI 43.0%-85.4%). Conclusions Our findings suggest that the proposed smartphone-based Ear Scale app can be useful in the evaluation of SSNHL in clinical settings where conventional pure-tone audiometry is not available.
