In the era of coronavirus disease 2019 (COVID-19), many healthcare professionals are being faced with the question of what is considered to be an essential service. This opinion paper has attempted to answer this complex question by understanding the potential relationship between dysphagia and COVID-19 and how speech-language therapists (SLTs) in South Africa should tackle this. It also aims to answer the question through the lens of a risk-benefit discussion based around practices and decision-making. Important gaps in the field relating to how SLT practices need to move forward during this challenging time have also been highlighted. Reflective questions that can assist SLTs when seeing dysphagia cases have been provided.

Background: South Africans have an increasing burden of hearing loss, especially in low-income rural areas. Limited information is available regarding caregivers' knowledge and views regarding infant hearing loss, which is essential for the successful implementation of early hearing detection and intervention (EHDI) programmes.
Objectives: The main aim of the study was to describe the knowledge and views of mothers with children aged between 0 and 5 years old regarding hearing screening, risk factors, symptoms of hearing loss, and intervention options for hearing loss.
Method: A survey was employed at a primary care clinic to gain insight into the maternal views on hearing loss and early intervention services for children aged 0-5 years old.
Results: The majority (83.2%) of the mothers believed that hearing can be tested at birth, 90.7% believed in the biomedical model of intervention which is based on cure, prevention, and pathology as opposed to traditional or alternative medicinal beliefs, and 95.3% indicated that they would seek medical attention if they noticed symptoms of hearing loss. Consequences of hearing loss, such as academic, communication and social problems, were indicated by 65.4% of mothers.
Conclusion: The findings demonstrated that although cultural beliefs regarding superstitious causes of hearing loss and use of traditional medicine exist, satisfactory maternal knowledge regarding detection and intervention for hearing loss is present. Maternal views are favourable and a general willingness to participate in EHDI programmes was present. This study advocates for the implementation of EHDI programmes at all primary healthcare clinics across South Africa.

Background: Augmentative and alternative communication (AAC) can enable individuals with little or no functional speech to communicate functionally in a variety of communication contexts. AAC systems for individuals who are not (yet) fully literate often require that the vocabulary for the system be preselected. By including the most commonly- and most frequently-used words (core vocabulary) in an AAC system, access to novel utterance generation can arguably be facilitated. At present, no Afrikaans core vocabulary list based on children's speech samples exists.
Objectives: This study aimed to identify the most frequently- and commonly-used words of South African Afrikaans-speaking Grade R learners without disabilities.
Method: Spontaneous speech samples were collected from 12 Afrikaans-speaking Grade R learners during regular preschool activities. Samples were transcribed and analysed to determine the number of different words used, the frequency with which each word was used, as well as the commonality of word use across the 12 participants.
Results: A total of 239 words met the criteria for inclusion in the core vocabulary (words used with a frequency of more than 0.05% in the sample, and used by at least half of the participants). These words accounted for 79.4% of words used in the entire speech sample.
Conclusion: The established core vocabulary consists of a relatively small set of words that was found to represent a large proportion of speech. AAC team members may consider including these words on Afrikaans AAC systems that are intended to give access to a measure of novel utterance generation.

Background: Evidence suggests that educators of deaf-blind students in the South African context have specific challenges in the educational setting because of their lack of adequate knowledge on deaf-blindness and a lack of sufficient training on communication, teaching and learning strategies.
Objectives: The aim of this study was to describe the challenges experienced by educators and assistant educators of children with deaf-blindness.
Method: Ten educators and assistant educators were selected purposively to participate in the study (Male = 3; Female = 7; age range 31-49 years). Participants were recruited from a school for the deaf-blind in Johannesburg. Participants completed semi-structured interviews on the challenges that they experienced when educating learners who are deaf-blind.
Results: Findings from the data after inductive thematic analysis suggested the following: (1) under-preparedness of educators and assistant educators, (2) communication challenges, (3) challenges related to the diversity of deaf-blind learners and (4) lack of support structures for educators and assistant educators.
Conclusion: There is a need for ongoing educator training on communication strategies, cultural diversity and inclusive strategies. A collaborative model of delivering training and inclusive education that will encompass educators and therapists as a means of supporting both the educator and the learner who is deaf and blind is needed. Such a collaboration may result in positive outcomes for both the educator and the deaf-blind learner.

Background: South African speech-language therapists are the only health professionals charged with dysphagia rehabilitation. However, registered nurses and doctors are often initial healthcare contact points for post-stroke dysphagia. Notwithstanding service concerns, they do indeed identify and manage post-stroke dysphagia. However, little is known about specifically what they do during these initial clinical encounters.
Objective: To explore how doctors and registered nurses, on initial clinical contact, identify and manage post-stroke dysphagia.
Method: A quantitative descriptive survey design, with non-probability, purposive sampling, was used. Twenty-one registered nurses and four doctors at a private South African hospital self-administered a questionnaire. Univariate analyses were completed by calculating frequency distributions of nurses' and doctors' identification and management practices.
Results: Most (86%) did not use a formal screening tool. Indicators screened informally included: presence of drooling (84%) or gag reflex (76%), level of alertness (80%) and spontaneous saliva swallow (80%). Participants neglected important indicators like voluntary cough and vocal quality. Management provided included head of bed elevation (96%), speech-language therapist referrals (92%), nasogastric tube insertions (88%), intravenous fluids (84%) and positional adjustments (76%). Alternative management included total parenteral nutrition (52%), syringe feeding (48%), swallow muscle strengthening exercises (56%) and swallow manoeuvres (52%).
Conclusion: Results indicated that doctors and registered nurses under-utilised important dysphagia indicators and used potentially harmful management practices like syringe feeding. Management practices further included out-of-scope methods like dysphagia rehabilitation exercises or manoeuvres. Recommendations include peer dysphagia screening training using formal tools and basic dysphagia management methods to better equip doctors and registered nurses when they clinically engage post-stroke patients.

Background: Treatment of cancer with cisplatin can result in hearing loss. Given the increasing burden of cancer in Africa, appropriate and timely identification, intervention and management of hearing loss in affected patients is of paramount importance.
Objectives: This study describes the perspectives and practices of healthcare professionals in relation to cisplatin-associated ototoxicity at an institution treating patients diagnosed with cancer.
Method: A concurrent triangulation study design was used to collect quantitative data from seven oncologists, nine nurses and 13 pharmacists using self-administered questionnaires, and qualitative data from four audiologists through semi-structured interviews for this hospital-based study, conducted in South Africa.
Results: Levels of awareness of cisplatin-associated ototoxicity varied with only 33% of the nursing personnel being aware in comparison to the oncologists and pharmacists. Oncologists were identified as the main custodians for providing information to patients. Whilst 82% of the participants considered the audiologist to be part of the oncology team, there was no provision for ototoxicity monitoring in the chemotherapy protocols, nor any ototoxicity-monitoring programme in place. There was no evidence that knowledge of cisplatin-associated ototoxicity translated into an appropriate management strategy for such patients.
Conclusion: Healthcare personnel overseeing the care and management of cancer patients need to improve their awareness of ototoxicity and refer timeously for audiological evaluation. Audiologists require greater awareness of monitoring programmes to appropriately implement and manage such programmes within a cancer platform and be part of a multidisciplinary team.

Background: For effective client outcomes, stuttering assessment and intervention approaches need to be aligned. This encompasses using assessment and intervention approaches that address the three multidimensional constructs of stuttering, namely core behaviours, secondary behaviours and negative feelings and attitudes.
Objective: The study aimed to explore whether multiple assessment measures could be used to describe the effectiveness of a comprehensive stuttering intervention approach, undergirded by the International Classification of Functioning, Disability and Health (ICF) framework.
Method: A single-subject case design was employed with one male adult who stutters. Data was collected by administering the Stuttering Severity Instrument-Fourth Edition (SSI-4) and Overall Assessment of the Speaker's Experience of Stuttering-Adults (OASES-A) at three testing periods (pre-intervention, immediately post-intervention and 7 months post-intervention), and a semi-structured interview schedule immediately post-intervention. Descriptive statistics was used to analyse the SSI-4 and OASES-A, and thematic analysis was conducted to evaluate the participant's interview schedule responses.
Results: The participant's total scores, impact scores and severity ratings of both the SSI-4 and OASES decreased across the three testing periods. The main theme of effectiveness of the comprehensive stuttering intervention to reduce aspects of disability emerged from the participant's responses.
Conclusion: Evaluation of the results from the assessment measures revealed that the comprehensive stuttering intervention approach was effective in reducing the participant's core behaviours, secondary behaviours and negative feelings and attitudes. Assessment and management of fluency disorders should promote a client-specific multidimensional approach that extends beyond the core behaviours and secondary behaviours, by addressing the underlying social and emotional facets of fluency disorders.

Background: Occupational activities performed by sound engineers are associated with hearing loss. However, there is a dearth of research on the hearing functions and the related hearing loss for sound engineers.
Objectives: To determine the hearing function and early effects of noise on the hearing ability of sound engineers, and to establish whether there are hearing conservation programmes (HCPs) available for sound engineer participants in Johannesburg.
Methods: A quantitative cross-sectional design was used. Eight sound engineers from the Academy of Sound Engineering (ASE) participated in the study. The following data were collected from the participants: case history data, ear-related symptoms and hearing conservation data. Hearing screening followed by full diagnostic audiological assessments was conducted for each participant. Descriptive statistics and one-sample t-test were used to analyse the data (confidence interval [CI] = 95%).
Results: Participants reported tinnitus and aural fullness as common complaints. Only one participant had a unilateral impacted cerumen. All the participants presented with hearing within normal limits bilaterally, with a percentage loss of hearing (PLH) of 1.1% for all the participants. However, five participants presented with a notched configuration that was ≥ 10 decibel (dB), in the high frequency region at 3000 Hz and 6000 Hz bilaterally. One-sample t-test (p = 0.001) inferred that at a mean age of 27.6 years (standard deviation [SD] = 3.85), a notch at 3000 Hz and 6000 Hz was associated with an early sign of a hearing loss for the study participants. An HCP was not in place at the study site.
Conclusion: The study indicated a younger age as an associated early sign of noise-induced hearing loss (NIHL) for the study participants, and that audiologists' clinical practice needs to explore HCP strategies specific for the sound engineers in order to prevent hearing loss.

Background: Recent estimates reveal that there are approximately 280 000 children between the ages of birth and 14 years who are living with the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) in South Africa. These children are living with a compromised immune system, are vulnerable to opportunistic infections and subsequent hearing loss. However, there is limited research on the nature and extent of this sensory impairment amongst school-aged children.
Objective: This study aimed to determine an audiological profile of a cohort of school-aged children attending an antiretroviral (ARV) clinic, describing the occurrence of hearing loss and nature in terms of degree, type, configuration and symmetry.
Methods: A non-experimental descriptive exploratory study was conducted, where 30 children aged between 6 and 12 years underwent diagnostic audiological assessments. Audiological procedures included case history, medical record review, otoscopic examination, immittance audiometry, pure-tone audiometry, speech audiometry, distortion product otoacoustic emissions (DPOAEs) and neurological auditory brainstem response (ABR) testing. The results were analysed descriptively using SPSS version 22 software.
Results: The results indicated abnormal otoscopic findings in half the participants, and consequently type C tympanograms were the most common. Of the 28 participants who could be assessed with pure-tone audiometry, 15 (54%) showed a hearing loss. A bilateral rising mild, conductive hearing loss was predominant. Thirteen (43%) of the participants could not be tested using DPOAE because of outer and middle-ear pathology. Neurological ABR testing revealed an abnormality in 18 (60%) of the participants suggesting the sensitivity of the ABR to detect subtle neurological changes.
Conclusion: Half the children in this study showed hearing loss, which has serious implications for the holistic management of the children within the health and educational contexts. Therefore, there is a need for audiological monitoring of children with HIV and AIDS.
背景:据最新估计,南非约有 28 万名出生至 14 岁的儿童感染了人类免疫缺陷病毒(HIV)和获得性免疫缺陷综合症(艾滋病)。这些儿童的免疫系统受损,很容易受到机会性感染,进而导致听力损失。然而,有关学龄儿童感官损伤的性质和程度的研究却十分有限:本研究旨在确定在抗逆转录病毒(ARV)诊所就诊的学龄儿童的听力概况,从程度、类型、结构和对称性等方面描述听力损失的发生情况和性质:我们进行了一项非实验性的描述性探索研究,对 30 名 6 至 12 岁的儿童进行了听力诊断评估。听力检查程序包括病史、病历审查、耳镜检查、沉降测听、纯音测听、言语测听、失真产物耳声发射(DPOAEs)和神经听觉脑干反应(ABR)测试。结果采用 SPSS 22 版软件进行描述性分析:结果显示,半数参与者的耳镜检查结果异常,因此 C 型鼓室造影最为常见。在 28 名可以进行纯音测听的参与者中,有 15 人(54%)出现听力损失。主要表现为双侧上升的轻度传导性听力损失。由于外耳和中耳病变,13 名参与者(43%)无法进行 DPOAE 测试。神经系统 ABR 测试显示,18 名参与者(60%)的听力出现异常,这表明 ABR 能够敏感地检测到细微的神经系统变化:结论:本研究中有一半儿童出现听力损失,这对儿童在健康和教育方面的全面管理产生了严重影响。因此,有必要对感染艾滋病毒和艾滋病的儿童进行听力监测。

Background: This article presents the details and findings of a practical implementation of a preliminary model for use in hearing conservation programmes (HCPs) in the mining sector in South Africa.
Objectives: The implementation is based on a previously published model, called feedback-based noise monitoring model (FBNMM), and represents its implementation as a tool of predicting occupational noise-induced hearing loss (ONIHL), as well as monitoring and managing HCPs in the mining sector within the South African context.
Method: The article, utilising real miners' data, demonstrates this basic static feedback model with its practical applications such as estimating, monitoring and providing quantitative information to aid miners, mining administrators and policymakers in decision-making around HCPs, as recommended in the previous 2019 publication by Moroe et al. This study was conducted in a South African platinum mine. Evidence on the model's sensitivity and practicability in early identification, intervention and management of ONIHL in the workplace is presented.
Results: Findings show how the use of the model within an HCP viewed as a complex intervention can allow for early prediction of ONIHL, consequently affording more accurate early intervention as part of preventive audiology within the health and safety goals of mines.
Conclusion: The feedback-based model should be a useful tool for successful implementation and monitoring of HCPs within South African mines.
