Chronic pain may have a significant impact on health-related quality of life and can be difficult to manage. In carefully selected patients, and as part of a comprehensive pain management strategy, opioid analgesia may help to achieve long-term pain control with a manageable side-effect profile and a low risk of serious adverse effects. However, appropriate evaluation, including biopsychosocial screening and risk screening is essential before initiating an opioid and during continued therapy. This guideline aims to assist practitioners in screening and selecting appropriate patients with chronic non-cancer pain to initiate, monitor and continue pain management with opioid therapy.

The workforce of 'physician--scientists' is ageing and decreasing in numbers. The responsibility to combat this trend rests on future generations of healthcare professionals and it is therefore valuable to evaluate medical students' attitudes towards research. ⋯ Students believed that research was important and had a positive attitude towards it. However, few had been involved in voluntary research and produced work worthy of presentation and/or publication. Addressing identified barriers and improving students' attitudes may begin to reverse the trend in declining numbers of physician--scientists.

The development of novel oral anticoagulants that are effective alternatives to warfarin in non-valvular atrial fibrillation (AF) is a welcome advance. However, a variety of unresolved problems with their use, and not least with their cost, make it important to re-evaluate the use of warfarin as it will likely remain the anticoagulant of choice in South African patients with non-valvular AF for the foreseeable future. ⋯ Guidance is provided on commencing warfarin treatment, maintenance dosing, the recommended steps when temporary withdrawal of treatment is necessary, the management of bleeding, and the use of warfarin in chronic kidney disease. Techniques for changing from warfarin to one of the new oral anticoagulants and vice versa are included.
