Case ReportsConcurrent peripheral pathologies and complex regional pain syndrome type 1 as contributors to acute post-stroke shoulder pain: a case report.
Post-stroke shoulder pain is associated with either a peripheral or central pathology. However, most of the time, it is challenging to establish a cause-and-effect relationship between the suggested pathology and shoulder pain reported. ⋯ Pharmacological and non-pharmacological treatment did not improve his shoulder pain. Later he developed complex regional pain syndrome (CRPS) of the right hand and the initial shoulder pain subsequently relieved following resolution of the CRPS.

About 30% of the population of the United States suffers from acute or chronic pain, often of unknown cause. Among this group might be included patients with symptoms claimed to be caused by a poorly defined condition called "chronic Lyme disease" in which chronic pain is a major contributor. Since there is no evidence to indicate that chronic Lyme disease is due to a persistent infection and that extended antibiotic therapy is beneficial and safe, this condition should not be viewed solely as an infectious disease problem. Rather, it should be considered within the context of a broad-based, multidisciplinary approach to determining the cause of chronic pain per se and developing more effective strategies for its treatment as outlined in a recent report on pain issued by the Institute of Medicine.

Comparative Study
Synergistic interaction of pregabalin with the synthetic cannabinoid WIN 55,212-2 mesylate in the hot-plate test in mice: an isobolographic analysis.
The aim of the study was to determine the type of interaction between pregabalin (a 3(rd)-generation antiepileptic drug) and WIN 55,212-2 mesylate (WIN - a highly potent non-selective cannabinoid CB1 and CB2 receptor agonist) administered in combination at a fixed ratio of 1:1, in the acute thermal pain model (hot-plate test) in mice. ⋯ Isobolographic analysis demonstrated that the combination of WIN with pregabalin at a fixed ratio of 1:1 exerted synergistic interaction in the mouse model of acute thermal pain. If the results from this study could be adapted to clinical settings, the combination of WIN with pregabalin might be beneficial for pain relief in humans.

A prospective cohort study. ⋯ Outcome definitions that combine ratings from perceived recovery scales with pain and disability measures provide the highest accuracy in discriminating recovered patients from nonrecovered patients.

We examined the analgesic effect of the selective kappa opioid receptor agonist SA14867 and the balance of its antinociceptive and sedative effects. The ED(50) values of SA14867 after oral administration for acetic acid-induced writhing, first and second phases of the formalin test, and rotarod test in mice were 6.1, 9.3, 2.7, and 19.5mg/kg, respectively. These values were smaller than those of the conventional kappa receptor agonists asimadoline and U-50488H. ⋯ Subcutaneously administered morphine (0.1-1mg/kg) improved the decreased pain threshold in a SART-stressed model; on the contrary, morphine did not inhibit the arthritis-induced decrease in the pain threshold. Moreover, orally administered SA14867 (0.1-1mg/kg) strongly attenuated mechanical allodynia and thermal hyperalgesia in a sciatic nerve ligation model. These results suggest that SA14867 has analgesic effects on chronic pain and may serve as a new therapeutic agent for pain treatment.
