Developments in diagnostic approaches for acutely dizzy patients

The acutely dizzy patient can be a diagnostic and management dilemma for emergency departments and general practitioners, with many patients consequently having delayed access to specialised assessment and treatment. David Jay tells us about HINTS, a bedside test that can...

The European School of Interdisciplinary Tinnitus

Scientific careers in tinnitus are expanding beyond any single discipline to embrace interdisciplinary collaboration and knowledge exchange. Natalia Trpchevska and Christopher R Cederroth present an overview of an innovative EU-funded training programme called the ‘European School of Interdisciplinary Tinnitus’, and...

Physiological mechanisms of hyperacusis: an update

Hyperacusis is a heterogeneous and complex clinical entity, and proposals about physiological mechanisms should reflect these issues. Ben Auerbach helps us navigate through present knowledge in this area, and proposes future directions for research. Hyperacusis is a debilitating hearing disorder...

Psychogenic vestibular disorders: understanding and management

‘Psychogenic vestibular disorders’, also known as ‘functional vertigo and dizziness’, are common causes of dizziness and balance difficulty. Although our understanding of their underlying pathophysiology remains incomplete, Drs Diego Kaski and Amy Edwards outline how early identification and positive diagnosis...

Pocket Atlas of Sectional Anatomy, Volume I: Head and Neck: Computed Tomography and Magnetic Resonance Imaging

Pocket Atlas of Sectional Anatomy, Volume I: Head and Neck, currently in its 4th edition, gives a thorough account of imaging of the head and neck in this single volume. Across its 792 illustrations, this edition has revised and expanded...

Hearing loss and cognition: something to think about

Irace, Chern and Golub propose causal and non-causal mechanisms for the links between hearing loss and dementia, concluding with a discussion of several proactive measures available to help preserve neurocognitive health in older adults with hearing loss. What is age-related...

New MRI technique assesses treatment response in skull base osteomyelitis

This paper describes another useful imaging technique to monitor Necrotising Otitis Externa (NOE). Echoplanar diffusion weighted magnetic resonance (DW MR) shows high signal on the ‘ADC map’ with active disease and this reduces in signal intensity as symptoms improve. This...

Consider PCR testing in culture negative necrotising otitis externa

Necrotising otitis externa (NOE) often does not yield identification of a causative organism to treat although in 90% of cases it is a member of the pseudomonas species. The incidence of fungal NOE is not to be forgotten and this...

How has management and outcomes of necrotising otitis externa changed over the past decade?

Necrotising otitis externa (NOE) remains a challenging condition for ENT departments, particularly with the increased prevalence of diabetes mellitus (DM) in the general population. There is no international consensus on treatment, although many institutions now have local guidelines drawn up...

A diagnosis-based scoring system to predict outcomes in necrotising otitis externa

Patients admitted with necrotising otitis externa have increased six-fold in the last 10 years. The prognosis is variable and dependent on co-existing morbidities. Charlston Comorbidity Index (CCI) is a weighted comorbidity scoring method, based on the presence or absence of...

Management of necrotising otitis externa

Although uncommon, necrotising (previously malignant) otitis externa (nOE) can be very aggressive, particularly if not managed appropriately. In this study the authors perform a retrospective review of 25 patients admitted with nOE over a four year period at a tertiary...

Indication and timing of electrodiagnostic tests in facial palsy

This excellent review describes the benefits and limitations of electrodiagnostic testing for patients with facial paralysis. Tests such as Schirmer, stapedial reflex and electrogustometry have been largely replaced by neurophysiologic tests like nerve excitability test (NET), electroneuronography (ENoG), surface electromyography...
