21 In the chapter on diabetes you wrote that you should avoid tablets before age of 40 years in non-insulin-dependent diabetes mellitus (NIDDM). Why is this, because in our country most doctors are prescribing this?

22 1. Should a patient poorly controlled on glibenclamide 15 mg a day and metformin 1500 mg a day be moved onto insulin? 2. What are the indications for insulin in type 2 diabetics?

23 What happens to the insulin-secreting capacity of a type 2 diabetic placed on insulin therapy earlier than recommended? Can the external supply of insulin improve the functional capacity of the insulin-secreting cells, to some extent by providing some rest to these cells?

24 1. Is inhaled insulin a suitable substitute for injectable insulin? 2. Is there, or will there soon be, insulin in the form of a tablet?

30 What is the urinary concentration or 24-hour urine albumin content above which angiotensin-converting enzyme (ACE) inhibitors should be started in diabetic patients? Does an albumin (in microgram)/creatinine (in milligrams) ratio above 30 in the morning sample indicate a need for this?
