    Patient-related benefits for adults with cochlear implantation : a multicultural longitudinal observational study
    (S. Karger AG, Basel, 2017-07-19) Lenarz, Thomas; Muller, Lida; Czerniejewska-Wolska, Hanna; Varela, Hector Valles; Dotu, Cesar Orus; Durko, Marcin; Irujo, Alicia Huarte; Piszczatowski, Bartosz; Zadrożniak, Marek; Irwin, Colin; Graham, Petra L.; Wyss, Josie
    ENGLISH ABSTRACT: To assess subjectively perceived, real-world benefits longitudinally for unilateral cochlear implant (CI) recipients in a multinational population treated routinely. To identify possible predictors of self-reported benefits. Design: This was a prospective, multicenter, repeated-measures study. Self-assessment of performance at preimplantation and postimplantation at 1, 2, and 3 years using standardized, validated, local language versions of the Speech, Spatial, and Qualities of Hearing Scale (SSQ), and the Health Utilities Index Mark 3 (HUI3) was performed. Outcomes were analyzed using a longitudinal mixed-effects model incorporating country effect. Patient demographics were explored for associations with change over time. Subjects: Two hundred ninety-one routinely treated, unilateral CI recipients, aged 13-81 years, from 9 clinics across 4 countries. Results: Highly significant improvements were observed for all outcome measures (p < 0.0001). Postimplantation, mean outcome scores remained stable beyond 1 year, with notable individual variability. A significant association for one or more outcomes with preimplantation contralateral hearing aid use, telephone use, age at implantation, implantation side, preimplantation comorbidities, dizziness, and tinnitus was observed (p < 0.004). Conclusions: Longitudinal benefits of CI treatment can be measured using clinically standardized self-assessment tools to provide a holistic view of patient-related benefits in routine clinical practice for aggregated data from multinational populations. Self-reported outcomes can provide medical-based evidence regarding CI treatment to support decision-making by health service providers.

    The simple bread tag – a menace to society?
    (Health and Medical Publishing Group, 2015) Karro, Ryan; Goussard, Pierre; Loock, James; Gie, Robert
    ENGLISH ABSTRACT: Foreign bodies (FBs) are potentially life-threatening when inhaled by a child, depending on where they lodge. Symptoms can range from acute upper airway obstruction to mild, vague respiratory complaints. Between 80% and 90% of inhaled FBs occlude the bronchi, while the larynx is a less common site. The commonest inhaled paediatric FBs are organic, e.g. seeds or nuts. Plastic FBs are less common and more difficult to diagnose. They are generally radiolucent on lateral neck radiographs and are often clear and thin. We report three cases of an unusual plastic laryngeal FB, the bread tag. Plastic bread tags were first reported in the medical literature as an ingested gastrointestinal FB in 1975. Since then, over 20 cases of gastrointestinal complications have been described. We report what is to our knowledge the first paediatric case of an inhaled bread tag, and also the first case series, briefly discuss the symptoms and options for removal of laryngeal FBs, and highlight the dangers of the apparently harmless bread tag. Images of the bread tags in situ and after their removal are included.

    Treatment of laryngeal lipoid proteinosis using CO2 laser
    (Health and Medical Publishing Group (HMPG), 2007-02) Kroukamp, Gary; Lehmann, Karen
    Lipoid proteinosis (Urbach-Wiethe disease, hyalinosis cutis et mucosae) is an autosomal-recessive condition with variable penetrance. It is characterised by distinctive skin and mucous membrane lesions, particularly on the eyelids, on the extensor surface of large joints and in the mouth. Laryngeal involvement is typical and causes hoarseness due to lesions on and around the vocal cords and occurs in 75% of patients with the condition. Patients are normally hoarse from infancy, and a chronic and benign course is usual.

    The effect of fequency tolerance on audiometer accuracy
    (Health & Medical Publishing Group, 1977) Guelke, R. W.; Floyd, J. D.; Van Zyl, F. J.
    Investigations into the methods used to calibrate audiometers reveal that the 6000 Hz frequency is particularly liable to yield inconsistent results when calibrated in the usual way. It is shown that the TDH39 telephone receiver which is usually calibrated on a 9A coupler in accordance with the International Standards Organization recommendation R389 will depend to a considerable extent on the precise frequency used and may differ by as much as 7 db when the frequency is varied but still retained within the specified tolerance limits. A new telephone receiver, the TDH50, is much less sensitive to frequency variation. It is shown that this receiver should be calibrated with the same threshold figures as the TDH39.
