Pain clinicians have always been challenged by the variability of response to pain treatment. Differences in the degree of pain stimulation and pain sensitivity, weight and age differences, prior opioid use and tolerance, as well as the differences in bioavailability of various opioid formulations have been cited as causes for the wide variability in analgesia seen with opioids. Genetics may explain the variability of responses and help to predict more effective (or less dangerous) medication choices and doses. Genetics may also help to predict the response to specific opioids and antidepressants. ⋯ Genetic testing may explain and predict many of the clinical responses seen with opioids and adjuvant medications, and may help the clinician identify those patients at genetic risk of opioid misuse and addiction.

Review Comparative Study
Chronic opioid therapy for chronic non-cancer pain: a review and comparison of treatment guidelines.
Long-term opioid use for chronic non-cancer pain has increased substantially in recent years despite the paucity of strong supporting scientific data and concerns regarding adverse effects and potential misuse. ⋯ There is a growing body of scientific evidence to support opioid use in chronic pain. Future work should focus on continuing to generate good-quality evidence on the long-term benefits of opioid therapy, as well as scientific data to guide drug choice and dosing for specific conditions, populations, and situations.

Chronic low back pain is considered as a high-impact condition that affects the working population of Latin America, with long reaching social and economic repercussions. Its true frequency is unknown due to the absence of well-designed clinical trials that use standardized definitions and criteria. ⋯ Despite the sparse information and the methodological heterogeneity of the studies, pooled results allowed for an indirect estimation of the prevalence of low back pain in the region that was pretty consistent with the published results obtained from other settings. New studies need to be carried out to supplement and overcome the methodological weaknesses of those previously conducted.
