Help The case study method enables specifically to work on these two axes. Marketing is a complex yet fluid field: multiple factors must be taken into accounting any decision. Unfortunately, it may be difficult to quantify many of these factors, and this makes the case method particularly suitable for education in marketing. The case study method, more than any other, requires judgement and intellectual rigour, analytical and decision-making skills: all these are essential in the field of business.

Question 11 I am a third-year student nurse and am currently researching a case study based on the biopsychosocial history of a patient who suffers from chronic hepatitis C, which initially occurred as a result of injecting drugs. I am confused about the biological effect of hepatitis: how exactly does it affect the liver? Question 12 What are the admission criteria for a case of acute viral hepatitis? Question 13 I would like to know where I can find details on hepatitis B virus (HBV) infection: chronic carrier, asymptomatic [normal liver function tests, HBV DNA/real-time polymerase chain reaction (PCR) 240 copies/mL, core less than 0.1]. Does a patient with such a profile need therapy or fine needle aspiration (FNA) biopsy? What is the possibility of hepatocellular carcinoma (HCC) in such a patient? Question 14 In chronic hepatitis B virus (HBV) infection, when anti-hepatitis B e antibody (anti-HBe) develops (seroconversion), the antigen disappears and there is a rise in alanine transferase (ALT). However, the graph in your book (K&C 7e, p. 337, Fig. 7.16) seems to show a fall in ALT at this point. Which is correct? Question 15 Interferon can be used in prophylaxis from hepatitis C after exposure. Could you explain how this can be used, and what degree of success can be expected as a result? Question 16 What is the latest recommended drug treatment for hepatitis C? Question 17 Can hepatitis C disease be treated in a carrier state completely by giving interferon? Question 18 I am a carrier of hepatitis C (HCV) and am going to have antiviral treatment soon. Are the side-effects of antiviral treatment for HCV bound to occur? I am very worried. Question 19 Besides needle-pricks, how else is it possible to contract hepatitis C from a hepatitis C (HCV)-positive patient? Are the patient's skin/sweat (or other bodily secretions) infectious? Question 20 What is the risk of infection with hepatitis C from blood splashed into the eyes?
