In September 2009 a new legislation for advance care planning was introduced in Germany with the important characteristics of bindingness and unlimited validity for individual directives. Knowledge regarding this act and the attitude towards its characteristics among patients is unclear. ⋯ The proportion of patients with a directive regarding advance care planning is only slowly increasing. Many patients are not well-informed, do not want to deal with dying or would like to delegate decisions to relatives and physicians. The present characteristics of the German legislation are controversially assessed and often do not represent the wishes of the patients.

Palliative care is an approach that improves the quality of life of patients with incurable and progressive illnesses; therefore, in these situations physiotherapy can play an important role. ⋯ Despite its significant potential to relieve symptoms, physiotherapy is not systematically integrated into palliative care practice in Germany.

Voltage-gated sodium channels (Navs) are crucial for the generation and propagation of action potentials in all excitable cells, and therefore for the function of sensory neurons as well. Preclinical research over the past 20 years identified three Nav-isoforms in sensory neurons, namely Nav1.7, Nav1.8 and Nav1.9. A specific role for the function of nociceptive neurons was postulated for each. ⋯ Recently, several gain-of-function mutations in Nav1.8 and Nav1.9 have been identified in patients suffering from painful peripheral neuropathies. However, another gain-of-function Nav1.9 mutation is associated with congenital insensitivity to pain. This review offers an overview of published work on painful Nav mutations with clinical relevance, and proposes possible consequences for the therapy of different pain symptoms resulting from these findings.

There is preliminary evidence that phantom pain is associated with disturbed organization of the sensory cortex and that this organization can be normalized with two-point discrimination (TPD) training. In this case study, a reduction in phantom pain and painful phantom sensation during a test period of 19 days, was achieved using an automated TPD procedure. In a patient with a transtibial amputation, pain levels decreased from a mean of 2.3/10 on the visual analog scale (VAS) to 1.3/10 (VAS) and the painful phantom sensation level decreased from a mean 3.7/10 (VAS) to 2.0/10 (VAS). These results show a positive trend, but are (except of the nocturnal pain attacks) rather of limited clinical relevance.
