The study aims to examine predictors associated with duloxetine adherence and its association with healthcare costs among fibromyalgia patients. ⋯ Fibromyalgia patients with higher duloxetine ADD were more likely to adhere to the therapy. High duloxetine adherence was associated with lower (Commercial) or similar (Medicare supplemental) healthcare costs.

Herpes zoster pain and postherpetic neuralgia (PHN) particularly affect older persons. This literature review presents how quality of life is evaluated and the consequences of shingles and PHN on the quality of life of older persons. Although more than 150 articles have been published on herpes zoster and its consequences, specific studies focusing on the older population are needed, in several domains like epidemiology, preventive medicine, neuropsychology, and pharmacology.

One indirect line of evidence for opioid-induced hyperalgesia (OIH) in humans is decreased pain thresholds (PTREs) and tolerances (PTOLs) in opioid addicts on opioids. There are a number of such studies in opioid maintained addicts, but no such studies in chronic pain patients (CPPs) with current opioid addiction. The objective of this study was to determine if this group demonstrates hyperalgesia. ⋯ This study contributes to the human OIH literature. However, because of the potential confounders in this study, the issue of OIH in humans remains unresolved.

Pain, motor, and sensory deficits characterize patients with a traumatic lesion of the brachial plexus. Frequently, more severe injuries co-exist that require immediate surgical attention. Early rehabilitation and physical therapy are the cornerstones of treatment. ⋯ Surgical reconstruction is frequently advised when nerves are disrupted. The results, mostly from small historical reports, vary greatly. Neurostimulation may have an additional beneficial effect, especially if the pathophysiology of nociception and neuropathic pain becomes evident in these complex patients.
