Upper gastrointestinal (GI) bleeds are a common presentation to emergency departments in the UK. The Glasgow Blatchford score (GBS) predicts the outcome of patients at presentation. Current UK and European guidelines recommend outpatient management for a GBS of 0. ⋯ The NPV of GBS in excluding any diagnosis at 0 was 43.55%. Two patients died as a result of GI bleeding, with a GBS score of 3. Therefore, we can conclude that, for non-variceal bleeds, the GBS can be extended to 2 for safe outpatient management, thereby reducing the number of bed days and pressure for urgent endoscopies.

Case Reports
Dilated cardiomyopathy as the first presentation of coeliac disease: association or causation?
Global ventricular impairment is a frequent presentation in clinical practice, but dissection of causative mechanisms from clinical associations is challenging. We present the case of a 19-year-old man who presented with dilated cardiomyopathy as the first presentation of coeliac disease. The manifestation of iron deficiency anaemia prompted gastroenterology input and enabled accurate diagnosis. ⋯ Mechanisms may relate to nutritional deficiencies or autoimmune myocarditis arising from cross-reactivity. We advocate early multidisciplinary involvement in such contexts to aid with management strategy. Despite adherence to a gluten-free diet, ventricular dysfunction persisted and he has been referred to a cardiac transplant centre.

Case Reports
Lesson of the month 2: A rare presentation of stroke: diagnosis made on magnetic resonance imaging.
Bilateral thalamic infarcts are uncommon posterior circulation strokes. The artery of Percheron (AOP) is a rare anatomical variant involving a singular arterial supply to both thalami and occlusion leads to bilateral thalamic infarction. We report the case of a 71-year-old man who presented with decreased consciousness (fluctuating Glasgow Coma Scale score of 5-7). ⋯ Computed tomography (CT) scan showed a mildly reduced attenuation in the region of the left thamalus. Subsequent diffusion-weighted magnetic resonance imaging (MRI) showed acute brainstem infarction, extending into the thalamus bilaterally, likely due to AOP occlusion. Bilateral thalamic infarcts due to AOP occlusion may not be recognised on initial CT scan and are more readily seen using diffusion-weighted MRI, which is the most beneficial imaging modality to aid in early diagnosis and treatment.
