A 48 year old lady presented with a 7-week history of progressive generalised myalgia and muscle weakness resulting in recurrent falls. Her past medical history included bipolar affective disorder and a previous stroke. Her medications included clopidogrel 75mg, atorvastatin 80mg, and quetiapine 400mg twice daily.
Abstract
Proximal muscle weakness can present acutely or subacutely to the Acute Medical Unit. Early diagnosis of the underlying pathology is essential due to life threatening complications such as respiratory failure and cardiac disturbances as well as causing significant levels of disability. The diagnosis requires thorough history-taking and examination to discern evidence of true weakness, assess its onset, distribution and severity followed by extensive investigations including a CK level, which if high should raise suspicion of rhabdomyolysis. Assessment of respiratory function should be done promptly to identify patients with associated respiratory muscle weakness and treatment should not be delayed waiting for definitive and confirmatory investigations. Poor response to treatment is unusual when diagnosis is correct; this raises the possibility of an alternative diagnosis.

Every acute physician has come across elderly patients presenting with muscle weakness and falls. Distinction between normal age related muscle wasting and pathological muscle atrophy can be difficult. It is important for acute physicians to be aware of the differential diagnosis of such a presentation. Inclusion body myositis(IBM) is the most common type of acquired myopathy above the age of 50.1 This article aims to highlight the diagnosis and management of this chronic illness. It is frequently misdiagnosed as polymyositis and wrongly treated with steroids.3 The typical symptoms and signs are illustrated by a recent case which presented to our department (see box 1).
