The aim of this study was to determine the ability of the central sensitization inventory (CSI), a new screening instrument, to assist clinicians in identifying patients with central sensitivity syndromes (CSSs). ⋯ The CSI is a useful and valid instrument for screening patients for the possibility of a CSS, although the chances of false positives are relatively high when evaluating patients with complex pain and psychophysiological disorders.

Chronic pain is a major characteristic feature of sickle cell disease (SCD). The refractory nature of pain and the development of chronic pain syndromes in many patients with SCD suggest that central neural mechanisms contribute to pain in this disease. We used HbSS-BERK sickle mice, which show chronic features of pain similar to those observed in SCD, and determined whether sensitization of nociceptive neurons in the spinal cord contributes to pain and hyperalgesia in SCD. ⋯ Compared with control HbAA-BERK mice, nociceptive dorsal horn neurons in sickle mice exhibited enhanced excitability as evidenced by enlarged receptive fields, increased rate of spontaneous activity, lower mechanical thresholds, enhanced responses to mechanical stimuli, and prolonged afterdischarges following mechanical stimulation. These changes were accompanied by increased phosphorylation of mitogen-activated protein kinases (MAPKs) in the spinal cord that are known to contribute to neuronal hyperexcitability, including c-Jun N-terminal kinase (JNK), p44/p42 extracellular signaling-regulated kinase (ERK), and p38. These findings demonstrate that central sensitization contributes to pain in SCD.

The prevalence of chronic pain has been estimated to be 19% in the European population and criteria for disabling chronic pain were found in approximately 7% of the German population. Clinical care for these patients is provided in ambulant and hospital-associated facilities. In this context, invasive interventions are part of the diagnosis and treatment of several specific diseases. Current data on the structure of clinical care based regional anesthesia for chronic pain patients in Germany are not available. ⋯ This survey describes the current structures of specialized pain facilities for regional anesthesia in Germany including responses from predominantly anesthesiologists in a hospital-associated setting. In light of the limited evidence in the literature there is no consensus on the interventional therapeutic management of chronic pain. Especially the application of a series of blocks and the frequency as well as criteria to support continuing or terminating a series of regional anesthesia interventions are not sufficiently evaluated. This survey also gives an incentive for a possible revision of the existing practice in regional anesthesia in the context of multimodal therapy and currently existing guidelines in future clinical studies.

Randomized Controlled TrialMagnesium sulfate with lidocaine for preventing propofol injection pain: a randomized, double-blind, placebo-controlled trial.
Pre-treatment with IV lignocaine and magnesium does not have an additive effect on reducing the pain of propofol injection compared with lignocaine alone.

ReviewLiver transplantation in the context of organ shortage: toward extension and restriction of indications considering recent clinical data and ethical framework.
The scarcity of liver grafts requires to optimize the results of transplantation. Extensions and alternatives of liver transplantation have to be regularly evaluated. ⋯ Before implementation of these potential changes into decisional algorithms for listing and organ allocation, their consequences, either for patient's individual benefit or for global transplant outcomes, should be closely evaluated using objective long-term end points and taking into account the ethical recommendations for organ transplantation.
