The number of people with dementia will rise dramatically over the next 20 years. Currently, one in three people over the age of 65 will die with dementia. A PubMed search using MeSH headings for 'dementia' AND 'palliative care' and for specific areas, i.e. enteral feeding. ⋯ People with dementia have poor access to good quality end-of-life care. Interventions such as antibiotics, fever management policies and enteral tube feeding remain in use despite little evidence that they improve quality of life or other outcomes. Research is required on the effectiveness of 'holistic' palliative care, outcome measures and the impact on carers and families.

Multiple sclerosis (MS) is the commonest disabling neurological condition to afflict young adults and therefore has a high social burden. Over several decades, there has been a considerable progress in the understanding of the disease pathogenesis as well as in the clinical management of MS patients. The emphasis in managing MS patients has shifted to multidisciplinary teams working in specialist groups. ⋯ This is an attractive concept that is not widely accepted. The observation that MS progresses despite immunosuppressive therapy suggests that MS may be a neurodegenerative disease with overlapping immune activation possibly in response to the release of central nervous system auto-antigens. The development of neuroprotective therapies for MS is required to prevent the devastating effects of long-term disability as a result of progressive disease.

During the past decades several rating scales have been developed to assess the functional status of patients with low back pain. ⋯ Further studies are required to evaluate the reliability, validity and sensitivity of the low back pain scoring systems used in the common clinical practice.

ReviewA 100 year update on diagnosis of tuberculosis infection.
Diagnosis and treatment of latent tuberculosis infection (LTBI) is a cornerstone of tuberculosis (TB) control in the developed world. In the last century, the tuberculin skin test (TST) was the only means of diagnosing LTBI. ELISpot and whole-blood ELISA, collectively known as interferon-gamma release assays (IGRAs), are promising new tools. ⋯ Current IGRAs are being improved and next-generation tests, with improved sensitivity, could enable the reliable exclusion of LTBI in immunocompromised individuals.

Assessing the causes of death across all regions of the world requires a framework for integrating, and analysing, the fragmentary information that is available on numbers of deaths and their cause distributions. This paper provides an overview of the met and methods used by the World Health Organization to develop global-, regional- and country-level estimates of mortality for a comprehensive set of causes, and provides an overview of global and regional levels and patterns of causes of death for the year 2004. The paper also examines some of the data gaps, uncertainties and limitations in the resulting mortality estimates. ⋯ Innovative methods involving sample registration, and the use of verbal autopsy questionnaires in surveys, are needed to address these gaps. Research on strategies to improve comparability of cause-of-death certification and coding practices across countries is also a high priority.
