Sorge and AJ Bombers both have a distinct personality and brand. Because of this, they each use social media in different ways. AJ Bombers is a case study in how to use social media events to drive business results. Events have long been an important part of retail and hospitality marketing, but Sorge has scaled them to a new level using social media

Question 1 What is favism? Question 2 What is the haemoglobin content of reticulocytes and how can this be measured or determined? Question 3 We are told that an erythrocyte sedimentation rate (ESR) above 100 mm/h has a limited differential diagnosis, mainly vasculitis, malignancy and granulomatous diseases. Could you explain whether that applies to an ESR after one hour or two? Question 4 What causes a raised erythrocyte sedimentation rate (ESR)? Question 5 What are the causes of very raised erythrocyte sedimentation rate (ESR)? I mean an ESR 100 mm/h. Is this test diagnostic in any disease besides polymyalgia rheumatica and giant cell arteritis? Question 6 1. Does the erythrocyte sedimentation rate (ESR) rise with age? 2. Can an ESR of 50 mm/h in an 80-year-old female with no evidence of systemic disease be considered normal? Question 7 1. What is a 'normal' erythrocyte sedimentation rate (ESR)? Is the equation of a normal ESR age

10, correct? 2. Would a normal ESR exclude a vasculitic cause in the case of stroke? Question 8 In which conditions is C-reactive protein (CRP) more informative than the erythrocyte sedimentation rate (ESR)? Question 9 What is the management of an isolated high ferritin (without any signs, symptoms or changes in the other blood investigations)? Question 10 Is the mean corpuscular volume (MCV) useful? What is the RDW and when is it used?
