Reliability of modified Dix-Hallpike test
Modifications of the Dix-Hallpike (DH) are sometimes necessary when the traditional DH is not feasible. The absence of any formal studies on modified DH was the idea behind this multicentre (three academic centres), prospective, randomised, single blinded and controlled clinical...
Vestibular screening in occupational medicine
Occupational vestibular disorders carry a high medico legal and economic burden. The occupational medicine physician must rely on rapid, non-invasive, economical and reproducible screening tests. This article compares the simplified caloric test of Veits (CTV) with the skull vibration-induced nystagmus...
Salivary pepsin – a simple test for LPR?
A diagnosis of laryngopharyngeal reflux (LPR) can be made on the basis of characteristic symptoms and nasendoscopy findings. Objective tests exist for this condition; for example, 24-hour dual-channel pH-metry which is considered to be the gold standard. Such tests are,...
Horizontal nystagmus: vestibular neuritis or lateral canal BPPV?
A horizontal nystagmus due to lateral canal (LSC) BPPV that is present in the upright position, that changes direction with head turn in the horizontal plane has been termed ‘pseudo-spontaneous nystagmus’ (PSN) because it mimics that of vestibular neuritis. The...
Listening effort and speech perception performance
Capturing speech perception performance in noisy listening environments is a key part in validating any hearing instrument. Traditionally audiologists have always measured this performance in noisy environments by looking at thresholds, i.e. speech reception thresholds or signal to noise ratios....Introduction to speech testing
Let’s get back to basics: Dr Schoepflin introduces the concepts behind speech testing for hearing care professionals. While pure tone threshold testing is considered the ‘gold standard’ for assessing auditory sensitivity, the results of pure tone testing provide only limited...
Allergy testing in children with beta-lactam hypersensitivity
The beta-lactam antibiotic is commonly used in treating ENT infections in childhood. However, its use can be limited by reported hypersensitivity or allergy to the antibiotic. This is largely attributed to the previous development of skin rashes while being on...
The vestibular system is not immune to chronic otitis media
It is well recognised that chronic otitis media (COM) is a risk factor for sensorineural hearing loss. Studies on the effect of COM on vestibular function have been beset by design biases. The authors designed a case control study to...Cognition and hearing – you can’t test one with the other!
Cognitive Psychologist, Boaz M Ben-David, provides insights into the import of considering cognitive factors when assessing speech perception ability to maximise intervention success. Failing to do so, he suggests, is “ageist”, a predisposition healthcare professionals must avoid. Cognitive performance is...100,000 Genomes Project: in conversation with Tess Lopez
For Jul/Aug 2021, ENT & Audiology News features several contributions from the 100,000 Genomes Project, and Tess Lopez very kindly agreed to talk to me about her involvement with the project, as well as sharing her personal experiences of having...
Diagnostic Audiology Pocket Guide: Evaluation of Hearing, Tinnitus, and Middle Ear Function
The Diagnostic Audiology Pocket Guide, as advertised, fits into a pocket. Albeit a larger one. This textbook takes the reader on a brief journey through routine diagnostic audiology testing procedures, including some less performed tests such as wide-band acoustic immittance...
