Lymphocyte subsets and the role of Th1/Th2 balance in stressed chronic pain patients
Background: The complex regional pain syndrome (CRPS) and fibromyalgia (FM) are chronic pain syndromes occurring in highly stressed individuals. Despite the known connection between the nervous system and immune cells, information on distribution of lymphocyte subsets under stress and pain conditions is limited. Methods: We performed a comparative study in 15 patients with CRPS type I, 22 patients with FM and 37 age- and sex-matched healthy controls and investigated the influence of pain and stress on lymphocyte number, subpopulations and the Th1/Th2 cytokine ratio in T lymphocytes. Results: Lymphocyte numbers did not differ between groups. Quantitative analyses of lymphocyte subpopulations showed a significant reduction of cytotoxic CD8+ lymphocytes in both CRPS (p < 0.01) and FM (p < 0.05) patients as compared with healthy controls. Additionally, CRPS patients were characterized by a lower percentage of IL-2-producing T cell subpopulations reflecting a diminished Th1 response in contrast to no changes in the Th2 cytokine profile. Conclusions: Future studies are warranted to answer whether such immunological changes play a pathogenetic role in CRPS and FM or merely reflect the consequences of a pain-induced neurohumoral stress response, and whether they contribute to immunosuppression in stressed chronic pain patients.

Ethical dilemmas in pain management
The purpose of this study was to survey the membership of the American Pain Society and the American Academy of Pain Medicine to determine their beliefs about ethical dilemmas in pain management practice. Respondents rated ethical dilemmas for their importance as well as their own competence in dealing with these ethical issues. The survey also included an open-ended question that asked respondents to describe clinical situations in which they had encountered ethical dilemmas. A total of 1,105 surveys were analyzed, with physicians (N = 612), nurses (N = 189), and psychologists (N = 166) representing the professions with the greatest response. Management of pain at the end of life, general undertreatment of pain, and undertreatment of pain in the elderly were the most frequently encountered dilemmas. Qualitative data were analyzed to identify ethical issues in the case examples provided by the respondents. Major themes included inappropriate pain management, barriers to care, interactions and conflicts with others, regulatory/legal issues, euthanasia, assisted suicide, and research issues. We conclude that ethical dilemmas are common in pain management practice and that resolution of these dilemmas requires commitment by individual professionals as well as health systems. © 2001 by the American Pain Societ
