Pain has become the most common accompanying symptom in patients seeking medical advice, and it is one of the main issues in public health. In Spain, there are no reliable data about the impact of pain in general population. The aim of the study was to estimate the prevalence of acute and chronic pain in the Spanish general population. ⋯ Regarding treatment, 61.7% of people complaining of pain said they were taking drugs. Source of drug treatment advice was a physician or a nurse in 66.4% of cases and self-prescription in 29%. It is concluded that pain, particularly chronic pain, has a high prevalence in the Spanish general population and a significant impact on occupational and social relationships.

The aim of this study is to estimate the prevalence and diagnostic pattern of pain at the primary care level during one year in a group practice. This practice serves the patients of a geographically defined area with approximately 14,000 inhabitants. ⋯ Painful states of the musculoskeletal system constitute more than 2/3 of painful states in primary care. Viewed from a primary care perspective, pain has a great impact on GPs' day-to-day activities and on health economy in general.

Randomized Controlled Trial Comparative Study Clinical Trial
Differential effectiveness of psychological interventions for reducing osteoarthritis pain: a comparison of Erikson [correction of Erickson] hypnosis and Jacobson relaxation.
The present study investigates the effectiveness of Erikson hypnosis and Jacobson relaxation for the reduction of osteoarthritis pain. Participants reporting pain from hip or knee osteoarthritis were randomly assigned to one of the following conditions: (a) hypnosis (i.e. standardized eight-session hypnosis treatment); (b) relaxation (i.e. standardized eight sessions of Jacobson's relaxation treatment); (c) control (i.e. waiting list). Overall, results show that the two experimental groups had a lower level of subjective pain than the control group and that the level of subjective pain decreased with time. ⋯ Results also show that hypnosis and relaxation are effective in reducing the amount of analgesic medication taken by participants. Finally, the present results suggest that individual differences in imagery moderate the effect of the psychological treatment at the 6 month follow-up but not at previous times of measurement (i.e. after 4 weeks of treatment, after 8 weeks of treatment and at the 3 month follow-up). The results are interpreted in terms of psychological processes underlying hypnosis, and their implications for the psychological treatment of pain are discussed.

Spinal cord stimulation (SCS) is an effective tool in alleviating neuropathic pain. However, a number of well-selected patients fail to obtain satisfactory pain relief. Previous studies have demonstrated that i.t. baclofen and/or adenosine can enhance the SCS effect, but this combined therapy has been shown to be useful in less than half of the cases and more effective substances are therefore needed. ⋯ In subsequent acute experiments, extracellular recordings from wide dynamic range neurones in the dorsal horn showed prominent hyperexcitability. The combination of SCS and gabapentin, at the same subeffective dose, clearly enhanced suppression of this hyperexcitability. In conclusion, electrical therapy and pharmacological therapy in neuropathic pain can, when they are inefficient individually, become effective when combined.
