December' s CME focuses on musculoskeletal (MSK) disorders, which represent a major disease burden and challenges in the developing world, mainly because of lack of resources and poor training in diagnosis and management. Many patients with diseases such as systemic lupus erythematosus and rheumatoid arthritis have reduced life expectancy and face a lifetime of pain and other problems. The advent of the synthetic disease-modifying anti-rheumatic drugs has significantly improved outcomes, but the challenge of early diagnosis and initiation of treatment remains in the developing world-and these drugs are expensive. MSK disorders still rank highest in prevalence as causes of chronic ill health, long-term disability and consultation with health professionals, as was shown in the Burden of Global Disease 2010 Study. This is against the background of MSK disorders contributing only 3.4% and 1.7% of the total disease burden in the developed and developing world, respectively. Osteoarthritis and low back pain remain the largest contributors to the global disability burden. The Bone and Joint Decade 2000-2010, endorsed by many organisations including the World Health Organization and many governments, has acknowledged the rising burden of MSK disorders. Dr Ayanda Gcelu and Prof. Asgar Kalla have put together an excellent issue of CME that will provide generalists in all spheres with a greater understanding of these important diseases.
