Diabetes mellitus is common in our increasingly affluent and ageing population. Although it is an old friend of practising family physicians, there is a need to be familiar with and up to date about the disease. As patients become more informed and receptive to current medical information, family physicians also need to stay current. This article highlights the evidences that have shaped our current treatment targets for type 2 diabetes mellitus.

Internationally, the United States (U.S.) cites the highest cost burden of low back pain (LBP). The cost continues to rise, faster than the rate of inflation and overall growth of health expenditures. We performed a comprehensive literature review of peer-reviewed and non– peer-reviewed literature from PubMed, Scopus, and Google Scholar for contemporary data on prevalence, cost, and projected future costs. Policymakers in the U.S. have long attempted to address the high-cost burden of LBP through limiting low-value services and early imaging. Despite these efforts, costs (~$40 billion; ~$2,000/patient/yr) continue to rise with increasing rates of unindicated imaging, high rates of surgery, and subsequent revision surgery without proper trial of non-pharmacologic measures and no corresponding reduction in LBP prevalence. Globally, the overall prevalence of LBP continues to rise largely secondary to a growing aging population. Cost containment methods should focus on careful and comprehensive clinical assessment of patients to better understand when more resource-intensive interventions are indicated.

BACKGROUND/AIMS: Recent studies reveal that acute gastroenteritis can precipitate irritable bowel syndrome (IBS) symptoms leading to the concept of post-infectious IBS. However, the overall contribution of gastroenteritis to the total IBS prevalence is unknown. In this exercise we try to estimate the contribution of gastroenteritis in IBS using the published literature and a longitudinal approach. METHODS: Existing literature was reviewed to determine the incidence of IBS after gastroenteritis, the rate of remission over time, data on rates of gastroenteritis in a given population and any patterns of resistance to these effects in human populations. This produced 3 models. The first assumed all humans were susceptible to gastroenteritis and its ability to produce IBS. The second assumed (using meta-analysis data) that 90% of humans in a given outbreak would be resistant to this effect. The third model used a high gastroenteritis exposure rate as might be seen in military deployment. RESULTS: In model 1, the prevalence was unrealistically high with an eventual steady state of 43.6% of the population affected by IBS. In a very conservative approach (model 2), steady state was achieved after 10 years to an overall prevalence of 8.9%. Interestingly, based on a high 1 year exposure rate such as military deployment, the maximum prevalence (steady state) was reached before 1 year suggesting high risk. CONCLUSIONS: Although hypothetical in approach, based on conservative estimates in existing literature the contribution of gastroenteritis to the overall prevalence of IBS is substantial.

10.Beyond low-density lipoprotein cholesterol: why, who and when.

Cardiovascular disease due to atherosclerosis is a leading cause of death around the world, including Singapore. Current treatment strategies primarily target low-density lipoprotein (LDL) cholesterol levels. Low levels of high-density lipoprotein (HDL) cholesterol and high triglyceride (TG) levels have been shown to increase the risk of coronary heart disease, but the clinical benefits of raising low HDL cholesterol have only been proven in a limited number of studies. This guide provides an approach on managing low HDL cholesterol levels in terms of lifestyle modifications and pharmacotherapy.
