Comparative Study
A comparison of chronic pain prevalence in Japan, Thailand, and myanmar.
Pain has been regarded as important in the improvement of quality of life (QOL). In the advanced countries of Europe and the North America, a number of large-scale epidemiological surveys on pain, particularly chronic pain, have thus been performed in general populations. However, few epidemiological surveys of chronic pain have been reported from developing countries, and no surveys appear to have examined chronic pain in the least developed countries. ⋯ The prevalence of chronic pain was significantly lower in Myanmar than in Japan or Thailand. With regard to the site and treatment of chronic pain, no clear tendencies were observed between countries, suggesting that frequency and the character of chronic pain differ from country to country around the world.

In more and more countries, a specific pain education curriculum is provided to instruct pain physicians. However, there is little literature on pain education and in particularly how to evaluate their knowledge. One of the modules interesting to assess is the use of clinical practice guidelines (CPGs) by pain physicians. ⋯ Case vignette is an interesting instrument for pain education because it is cheap, easy to use, and can be repeated. However, training before using this instrument is needed for pain physicians, in particular during their pain education.

Spinal cord stimulation (SCS) is an established treatment option for chronic pain. Prior to permanent implantation, temporary trials are performed to evaluate the SCS treatment. During the trial period, it is common for the patients to experience changes in paresthesias. However, it is unclear what the role of lead migration is, if any, in the changes in paresthesia. ⋯ This case series demonstrates continued support for the role of the width of the cerebral spinal fluid space as the significant factor on paresthesia changes in SCS with respect to postural changes, even during the trial period.

Review Meta Analysis
Prevalence of pain among nonmedical prescription opioid users in substance use treatment populations: systematic review and meta-analyses.
Prescription opioid analgesics (POA) are widely used in the pharmacotherapeutic treatment of acute and chronic pain in North America, where nonmedical prescription opioid use (NMPOU) has become a substantial public health concern in recent years. Existing epidemiological data suggest an association between NMPOU and pain problem symptoms in different populations, including samples in substance use treatment, although the extent of these correlations has not been systematically assessed. ⋯ Pain symptoms are disproportionately elevated in substance use treatment samples reporting NMPOU. Effective measures to prevent and treat NMPOU are urgently needed, although a substantive extent of NMPOU observed in this specific context may relate directly or indirectly to the presence of pain, e.g., either as an expression of ineffective pain care or as a consequence of previous POA-based interventions. At the same time, effective ways to treat and address ongoing pain issues in NMPOU samples need to be implemented, which may require ongoing opioid-based pharmacotherapeutic care aimed at both pain and dependence.
