The ORL-1 receptor is expressed by human leukocytes. Limited knowledge exists about the function and interaction between the nervous and immune systems. The aim of our study was to investigate the expression of the nociceptin-ORL-1 receptor system on different leukocyte subsets and the influence of the ORL-1 receptor on the intracellular production of cytokines. ⋯ The ORL-1 receptor is expressed by all subtypes of leukocytes. The function of this receptor is not the modulation of cytokine production and requires further studies.

Each individual is entitled to an adequate and sufficient pain therapy. However, only a few studies have examined the peculiarities of pain management in drug-dependent or formerly addicted patients. Any addiction is disadvantageous for a successful pain therapy, since some of the prescribed drugs may themselves cause addiction. ⋯ There are adequate pain therapies for addicted patients. The best results are achieved by taking into account the physiological and psychological peculiarities of drug-dependent patients. Importantly, this should be combined with a variety of different, optimized, multimodal therapeutic regimes, as well as with an interdisciplinary approach.

Case Reports Comparative Study
[Deep brain stimulation in the posterior hypothalamus for chronic cluster headache. Case report and review of the literature].
Primary chronic cluster headache (CCH) is a rare but severe pain syndrome and pathophysiological explanations are still missing. PET studies revealed activation in the hypothalamus and therefore it became a target for therapeutic deep brain stimulation (DBS). A case of a 39-year-old woman and a literature review are presented. ⋯ After 7 days the stimulation device was implanted subcutaneously. DBS with implantation of a lead in the ipsilateral inferior posterior hypothalamus is an experimental treatment option and should be offered to selected patients in a prospective controlled clinical trial. Data concerning the long-term follow-up need to be collected.

Comparative Study
[Acupuncture for chronic pain patients. Treatment outcomes--the role of the acupuncturist].
These results are relevant to the choice of appropriate criteria for quality assessment of acupuncture and emphasize the role of patient satisfaction within quality assurance. Pre- and post-treatment differences in a set of pain related measurements were determined using a combination of data from an observational study and a survey of physicians. The following features of the physicians' study were investigated: specialisation, qualification in acupuncture, rate at which patients received acupuncture, use of further, complementary methods in the practice. ⋯ However, these differences had disappeared 6 months after the onset of acupuncture. These longer term effects were more pronounced for physicians offering additional complementary methods in their practice. Improvement after acupuncture and patient satisfaction were positively correlated.
