It has now been established that sleep deprivation or fragmentation causes hyperalgesia which cannot be explained by a general change in somatosensory perception. However, it has not yet been clarified which of the sleep stages are most relevant for this effect. The seemingly paradoxical effects of sleep deprivation on pain-evoked brain potentials on the one hand and the subjective pain report on the other hand suggest complex changes in gating mechanisms. ⋯ Together with results from animal research the finding that endogenous pain modulation (CPM) is impaired by sleep deprivation suggests that the serotoninergic system mediates the effect of sleep deprivation on pain perception. However, other neurotransmitters and neuromodulators still have to be considered. The clinically relevant question arises why sleep deprivation induces hyperalgesia more easily in certain individuals than in others and why this effect then has a longer duration?

Controlled Clinical Trial
[Evaluation of the German new back school : Muscular physiological characteristics.]
According to the biopsychosocial approach of the German new back school the core objectives are sustainable improvement of physical and psychosocial health resources. Subjects with non-specific low back pain were investigated to evaluate the desired physical effects. ⋯ The adjustment effects at 12 months follow-up indicate a delayed positive influence of the new back school program on muscular physiological parameters. Individuals with chronic non-specific back pain showed a long-term profit from participation in the new back school program due to the initiated orientation to a modified more active lifestyle.

Practice Guideline
[Consensus paper of the German Migraine and Headache Society on the structure of headache care facilities in Germany].
This consensus paper introduces a classification of headache care facilities on behalf of the German Migraine and Headache Society. This classification is based on the recommendations of the International Association for the Study of Pain (IASP) and the European Headache Federation (EHF) and was adapted to reflect the specific situation of headache care in Germany. It defines three levels of headache care: headache practitioner (level 1), headache outpatient clinic (level 2) and headache centers (level 3). The objective of the publication is to define and establish reliable criteria in the field of headache care in Germany.

In 2007, the German national guidelines on "Treatment of acute perioperative and post-traumatic pain" were published. The aim of this study was to describe current structure and process data for acute pain management in German hospitals and to compare how the guidelines and other initiatives such as benchmarking or certification changed the healthcare landscape in the last decade. ⋯ The survey was representative by evaluating 20 % of all German hospitals. The organizational requirements for appropriate pain management recommended by the German guidelines for acute pain recommended have been established in the hospital sector in recent years. However, the organizational enforcement for acute pain management in nonsurgical areas is not adequate yet, compared to the perioperative care. In all hospitals modern medication and invasive techniques are widely available.

The diagnosis of medication-overuse headache (MOH) is of central importance because this secondary headache disorder can be treated very effectively and patients do not usually respond to headache prophylaxis as long as MOH persists. The article describes important changes in the diagnostic criteria of different MOH subtypes after publication of the International Classification of Headache Disorders (ICHD-3beta) in 2013. The new classification has a crucial and direct impact on prevention and treatment of MOH. ⋯ In uncomplicated cases, the results of these three treatment settings do not differ. From a cost-effectiveness standpoint, the outpatient treatment should be given priority. In complicated cases, a fully inpatient withdrawal treatment using a multimodal treatment concept is significantly superior.
