Managerial case study, Since the late 1990s, the Internet has been widely used as a channel for communication and e-commerce by individuals and businesses. The use of Internet involves several cyber risks such as hacking, systems getting infected by viruses and worms, identity and credit card frauds and breach of network security.

These cyber risks were not covered by regular insurance policies. The US-based AIG, a leading insurance and financial services provider in the world, launched AIG e-business Risk Solutions (AIG eBRS) in 2000 exclusively to address these cyber risks.

The case explains how AIG eBRS made the e-insurance policies flexible and brought down their costs through technological alliances, thus facilitating even small and medium size companies to avail such insurance. It describes the product portfolio and the strategies of AIG eBRS, which enabled it to emerge as the largest provider of e-business risk insurance worldwide with over 70 per cent market share.

1 I would like to know the exact mechanism of entry of potassium into cells under the influence of insulin.

2 I am seeing an increasing number of diabetic patients in primary care who have elevated fasting blood glucose readings but postprandial measurements that are normal or only slightly high. Does this indicate insulin resistance in these patients? What is the reason for this trend?

3 What are the latest diagnostic criteria for the diagnosis of diabetes mellitus?

4 What test is recommended for diabetes and can the same be used to diagnose diabetes in a child?

5 What is the value of glycosylated haemoglobin (HbA1C) in diabetes mellitus?

6 I read in a book that in diabetics the random blood sugar is more important than the fasting; on a medical website I noted that, for a patient with type 2 diabetes, the fasting blood sugar level is more important. What do you say? Is it acceptable to let the fasting blood sugar remain at approximately 1.5 mmol/L above the upper limit in a patient of60 years with type 2 and presently on oral therapy?

7 In type 2 diabetes, which blood sugar - fasting or random - is more revealing prognostically? Question 8 Why are the fasting and 2-hour blood glucose levels needed in a diabetic patient being treated with oral antidiabetic drugs?

9 Is it sufficient to use a fasting blood sugar and glycosylated haemoglobin (HbA1C) level as a guide to modify the insulin or oral antidiabetic dose without considering the 1 and 2 hour postprandial values?

10 What is the value of the 2-hour postprandial blood sugar level above which the dose of an oral antidiabetic should be increased if this value is exceeded several times despite dietary modification?
