Observational Study
Using a graphical risk tool to examine willingness to take migraine prophylactic medications.
Many migraine sufferers use daily prophylactic therapy to reduce the frequency of their headache attacks. The Food and Drug Administration has approved several different medications for migraine prophylaxis, but it is not clear whether sufferers perceive these treatments to provide clinically significant benefits given their side effect profiles. Three hundred headache sufferers were recruited from the community and local headache clinics using print and television advertising. ⋯ However, <60% of participants reported willingness to take any of these medications even if they provided a 50% reduction in headache frequency. Several general predictors of willingness to take were observed including high headache-related disability, depressive symptoms, and pain medication concerns including fear of tolerance. These findings suggest that if properly informed of the side effect profiles of these medications, many patients might opt for other treatments.

Diabetic polyneuropathy (DPN) is a major cause of neuropathic pain and a frequent target condition in analgesic treatment trials. Differences in the clinical symptoms and signs associated with DPN suggest distinct pathophysiological mechanisms underlying nerve damage and dysfunction that are likely to have therapeutic relevance. The aim of this study was to develop a tool for the bedside assessment of painful neuropathies such as DPN that captures the diversity of phenotypes. ⋯ We combined interview questions and physical tests identifying these differences in a shortened assessment protocol that we named Standardized Evaluation of Pain and Somatosensory Function (StEPS). The protocol StEPS generates a phenotypic profile of patients with neuropathy. Separate intensity ratings for spontaneous painful symptoms and pain evoked by standard stimuli support a detailed documentation of neuropathic pain and its response to analgesic treatment.

Complex regional pain syndrome type I (CRPS-I) highly affects patients' ability to perform daily life activities. Pain-related fear might be a key target to reduce disability in chronic pain. Current treatments aiming at reducing pain show little improvements on pain and disability, whereas novel exposure-based treatments targeting pain-related fears have shown to be promising. ⋯ EXP was superior in reducing lower extremity disability from pretreatment to 6-month follow-up (3.624; 95% CI, 0.467-6.781; P = 0.02), but not from pretreatment to posttreatment (3.055; 95% CI, -0.018 to 6.128; P = 0.054). All secondary outcomes significantly favored EXP pretreatment to posttreatment, as well as pretreatment to 6-month follow-up. Exposure to daily activities shows to be more effective than a protective pain-contingent TAU in reducing self-reported disability in daily life of CRPS-I patients with at least moderate levels of pain-related fear.
