ABSTRACT

The authors present two elderly patients with chronic subdural haematomas following minor trauma. The difficulty associated with making the diagnosis is discussed. A high index of suspicion and routine follow-up of such patients is recommended in order to promote early diagnosis and prompt treatment of this reversible cause of dementia.

INTRODUCTION

Myelinated retinal nerve fibres have been associated with various conditions such as myopia, amblyopia, retinal vascular anomalies and vitreomacular traction syndrome (1, 2, 3). We present two patients with extensive macular myelination associated with retinal detachment and one of them posed a diagnostic challenge.

ABSTRACT

We present a case of a 50-year old man who developed mutism and a flaccid quadriparesis within 48 hours of presentation to hospital with severe hyponatraemia. A diagnosis of central pontine myelinolysis was made based on the clinical features and typical appearances on magnetic resonance imaging.

ABSTRACT

Human infection caused by Chromobacterium violaceum is rare but when it occurs, it is associated with a high mortality rate. This is a report of a young adult male who presented as a surgical emergency and succumbed soon after. The most common feature of this infection is sepsis, followed by cutaneous involvement and liver abscesses. Chromobacterium infection as a differential in a case of sepsis is important for clinicians to suspect, especially in tropical countries.
