The aims of this study were: (1) to compare two groups of patients with chronic pain conditions (work-related muscular pain, mainly low back pain, and fibromyalgia) in general coping and pain-specific coping; (2) to examine the relationship between general and pain-specific coping and, (3) to examine the influence of state-trait anxiety on general and pain-specific coping. The sample included 80 individuals (range=19-70 years; mean=47; SD=9.9), who were patients at two pain management clinics for examination of their physical and psychosocial health conditions and consideration on disability pension. The patients were asked to respond to theStrategies to Handle Stress Questionnaire, theCoping Strategies Questionnaireand theState-Trait Anxiety Inventory. ⋯ Anxiety-prone patients with fibromyalgia might benefit from psychological support in the process of coping with pain.

Injured sensory axons trapped in a neuroma or freely regenerating in the distal nerve stump, frequently display ectopic mechanosensitivity, spontaneous impulse discharge or both. This abnormal neural activity is thought to contribute to spontaneous and movement-evoked neuropathic paraesthesias, dysaesthesias and pain, as well as to allodynia and hyperalgesia. ⋯ This suggests that mechanosensitivity and spontaneous firing are aspects of a single underlying pathophysiological process.

Tramadol is a widely-used analgesic for pre- and post-operative pain which has a different pharmacological profile to that of classical opioids, since it does not induce respiratory depression, constipation, sedation, tolerance or dependence. However, tramadol frequently produces nausea and vomiting as side-effects. In the present study, the interactions between tramadol and several adrenergic and serotonergic compounds with antinociceptive activity were studied by isobolographic analysis. ⋯ The synergies observed with these combinations suggest a complex modulation of the descending noradrenergic and serotonergic systems that exert inhibitory influences on the transmission of nociceptive information, probably in addition to effects on receptors in the primary neurons of the spinal cord. The co-administration of analgesic drugs that produce superadditive effects constitutes a significant new avenue for the treatment of pain, since a similar level of antinociception can be obtained with considerable reductions in the dose of each analgesic.
