Review Meta Analysis
The impact of genetic variation on sensitivity to opioid analgesics in patients with postoperative pain: a systematic review and meta-analysis.
Individual response to opioid analgesics varies among patients. ⋯ The results indicate that among the genetic SNPs we studied which include those affecting analgesic drug metabolism, transport of analgesic agents across the blood-brain barrier, and their activity at target receptors and ion channels and in the modulation of neurotransmitter pathways, the A118G allele variant of OPRM1 has the most potent influence on pain management of postoperative patients. Opioid receptor gene information may provide valuable information for clinicians to properly manage the analgesic use of opioids individually for better pain management.

In summary, the SGR continues to hang like Damocles sword over physicians. To understand health care needs, we need to separate basic health care needs from economic mandates, and health insurance from health care coverage. The SGR flux represents another meaningful uncertainty to this health care conundrum.

Cervicogenic headache is a secondary headache that has a source in the upper cervical spine. There is a small but growing body of evidence to establish effectiveness of radiofrequency (RF) neurotomy, and the pulsed RF (PRF) procedure for management of cervicogenic headache. ⋯ There is limited evidence to support RF ablation for management of CHA as there are no high quality RCTs and/ or multiple consistent non-RCTs without methodological flaws. There is poor evidence to support PRF for CHA as there are no high quality RCTs or Non-RCTs.

Blood testing is quickly becoming a useful laboratory tool for opioid prescribers who wish to document and assess patient tolerance, more objectively monitor patient safety, and evaluate patient compliance using information that is not available with traditional urine drug testing (UDT). Blood testing does not need to be performed as frequently as UDT but provides extremely valuable information which can be used to more accurately evaluate patient compliance and assist with interpreting blood toxicology results commonly used in impairment or overdose cases. This narrative review presents the current evidence supporting the use of blood testing within the chronic pain management setting. ⋯ Prescribers must also be aware that this type of laboratory testing need only be administered to chronic pain patients receiving daily opioid therapy. Patients taking infrequent, low dose, or as needed medications are not anticipated to benefit from this type of test. Based on the complexity of both achieving acceptable outcomes with opioid treatment and the legal and societal issues at hand, we feel that the addition of blood concentration levels will become the standard of care in the near future.
