1.Diabetes control- the legacy of a memory
Journal of University of Malaya Medical Centre 2009;12(2):47-56
Achieving and maintaining good glycaemic control remains an important goal in the management
of this common and prevalent disorder. Recent evidence from important megatrials, ACCORD,
ADVANCE, VADT, UKPDS-10 year follow-up as well as the STENO-2 follow-up study, have cleared
doubts concerning the benefits of targeting good glycaemic control. For the first time, we have
the reassurance that macrovascular benefits can be realised from good glycaemic control. The
legacy effect of prior good glucose control from the UKPDS-10 year follow-up, reinforces the
results seen from the DCCT-EDIC (for Type 1 diabetes). The Intervention Phase of the UKPDS
revealed benefits for reduction of microvascular complications, while it was only at the end of
the Post-Trial Monitoring Phase where significant improvements in both micro and macrovascular
outcomes were seen.
The other three Trials assessing the effect of glycaemic control on cardiovascular outcomes,
although largely negative for CV benefit, give valuable insight towards appropriate patient
characteristics for which aggressive glucose control can and should be instituted. Individualising
glycaemic targets, which has been the approach that many clinicians have been practising, has
received new impetus albeit with clearer details.
Getting to glycaemic goal early in the course of T2DM and Doing to Safely (Avoiding hypoglycaemia)
are the key ingredients to successful management. The legacy of the memory of initial good
metabolic/glycaemic control is investment in good health with benefits of reductions in both
micro and more importantly, macrovascular disease, years later.
Multifactorial interventions that include blood pressure, lipid lowering in addition to glucose
control in these individuals with the Metabolic Syndrome result in more immediate beneficial
additive effects on cardiovascular outcomes.

2.Oncogenic osteomalacia, you say? better start looking then - a case report

Tumour-induced or oncogenic osteomalacia (OOM) is a rare paraneoplastic syndrome characterized
by bone pain and muscle weakness. A biochemical profile consisting of normocalcaemia,
hypophosphataemia, phosphaturia, increased serum alkaline phosphatase and inappropriately
low serum levels of 1, 25-dihydroxyvitamin-D is diagnostic. OOM is usually caused by an osseous
or soft-tissue tumour of mesenchymal origin that secretes phosphaturic substances leading to
increased urinary phosphate wasting. These tumours are small and slow growing. The diagnosis
continues to be easily missed and when eventually made, localization of the tumour can be
difficult. We describe the case of a young man who presented with severe generalized pain
associated with muscle weakness. He was extensively investigated and eventually diagnosed to
have OOM 3 years after initial presentation. Specialized investigations were necessary to localize
the offending tumour.
3.Carbimazole-induced aplastic anaemia - a case report

Antithyroid drugs have been used for more than 50 years for the management of hyperthyroidism.
Most patients tolerate treatment well, but some may develop rare life threatening side effects such
as agranulocytosis and aplastic anaemia. Clinical experience with the latter condition is extremely
limited. We report on a case of carbimazole-induced aplastic anaemia caused by hypocellular bone
marrow and associated plasmacytosis in a thyrotoxic patient chronically treated with carbimazole.
This resolved after substitution with propylthiouracil. The clinical course was complicated by
neutropaenic septicaemia and atrial fibrillation.
