Numerous studies support the theory that pregabalin causes an antihyperalgesic effect, which could be potentially beneficial in a perioperative setting. By binding to calcium channels pregabalin reduces the release of excitatory neurotransmitters and therefore inhibits central sensitization. ⋯ Although strongly supported by theoretical considerations the routine preoperative application of pregabalin for the prevention of hyperalgesia cannot be recommended due to the lack of clinical studies. Future studies should incorporate secondary hyperalgesia and allodynia as primary parameters.

Glossopharyngeal neuralgia is a rare condition and the origin is mostly idiopathic. Causes of symptomatic glossopharyngeal neuralgia can be tumors, infarction or trauma. ⋯ This improvement was maintained at 1-year follow-up. This is the first report of development of glossopharyngeal neuralgia after resection of a glossopharyngeal schwannoma.

Randomized Controlled Trial Comparative Study
[Levobupivacaine vs. ropivacaine for continuous femoral analgesia after anterior cruciate ligament reconstruction].
Levobupivacaine and ropivacaine are both used for continuous femoral analgesia after anterior cruciate ligament reconstruction; however it is unknown whether both drugs are equally effective regarding pain control, preservation of mobility and patient satisfaction. ⋯ Postoperative analgesia for ACL reconstruction during the first 48 h using femoral block with a continuous infusion of levobupivacaine 0.125% or ropivacaine 0.2% in combination with an IVPCA is similarly effective and better than a placebo. Both studied drugs seem to be equally appropriate for this purpose.

Multicenter Study
[Success of treatment in higher stages of pain chronification as well? An evaluation of the Mainz pain staging system based on the QUAST-analysis sample].
More than 10 years ago Gerbershagen gave a pessimistic prognosis for treatment success in patients with higher stages of pain chronification. To date only few studies concerning this statement exist and the results are inconsistent. The objective of this study was to evaluate the prognostic validity of the Mainz pain staging system (MPSS) in a large multicenter sample. It was assessed whether effects of treatment in patients with higher stages of pain chronification are less than those in other patients. Of further interest was whether treatment success is related to different outcome measures. ⋯ According to the view of the patients, treatment in specialized pain centres is successful even in the highest stage of pain chronification. This notwithstanding, success of treatment must not be confounded with the efficacy of an intervention. It has to be noted that the results of the current study do not allow conclusions regarding efficacy of treatment.
